Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as difficulties
with respect to valuation. Changes in the value of a derivative may not correlate perfectly with the
underlying asset, rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

of stocks. Value stocks also may underperform the market for long periods of time.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

|
| Small and Mid-Cap Company Risk |
Small and
Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Risks of Concentrating in the Real Estate Industry |
Risks of Concentrating in the Real Estate Industry: A fund that concentrates (i.e., invests more than 25% of its
net assets) its investments in securities of companies in the real estate industry will be exposed to
the general risks of direct real estate ownership. The value of securities in the real estate industry
can be affected by changes in real estate values and rental income, property taxes, and tax and regulatory
requirements. Also, the value of securities in the real estate industry may decline with changes in interest
rates. Investing in REITs and REIT-like entities involves certain unique risks in addition to those risks
associated with investing in the real estate industry in general. REITs and REIT-like entities are dependent
upon management skill, may not be diversified, and are subject to heavy cash flow dependency and self-liquidation.
REITs and REIT-like entities also are subject to the possibility of failing to qualify for tax free pass-through
of income. Also, because REITs and REIT-like entities typically are invested in a limited number of projects
or in a particular market segment, these entities are more susceptible to adverse developments affecting
a single project or market segment than more broadly diversified investments. The performance of a fund
may be materially different from the broad equity market.

Market Trading
Risk: Active trading markets for the ETF Class shares may not be
developed or maintained by market makers or authorized participants. Authorized participants are not
obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation
units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances.
There can be no assurance that the requirements of the listing exchange necessary to maintain the listing
of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market
for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets
for the fund’s portfolio holdings, which may cause a significant variance in the market price of
the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’
bid-ask spread.
|
| Premium/Discount Risk |
Premium/Discount Risk:
The net asset value (“NAV”) of the ETF Class shares and the value
of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s
holdings, the existence of extreme market volatility or potential lack of an active trading market for
shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to
NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when
the market price is at a discount to the NAV, the shareholder may sustain losses.

| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality. The following is a description of additional principal risks
of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a
national securities exchange.
|
| Market Trading Risk |
Market Trading Risk: Active
trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized
participants. Authorized participants are not obligated to make a market in the ETF Class shares or to
submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in
shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements
of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be
met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less
liquid in response to deteriorating liquidity in the markets for the fund’s portfolio holdings,
which may cause a significant variance in the market price of the ETF Class shares and their underlying
value as well as an increase in the ETF Class shares’ bid-ask spread.
|
| Premium/Discount Risk |
Premium/Discount Risk: The net asset value (“NAV”)
of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and
redemptions or the market price of a fund’s holdings, the existence of extreme market volatility
or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares
trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when
the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount
to the NAV, the shareholder may sustain losses.

shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements
of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be
met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less
liquid in response to deteriorating liquidity in the markets for the fund’s portfolio holdings,
which may cause a significant variance in the market price of the ETF Class shares and their underlying
value as well as an increase in the ETF Class shares’ bid-ask spread.
|
| Premium/Discount Risk |
Premium/Discount Risk: The net asset value (“NAV”)
of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and
redemptions or the market price of a fund’s holdings, the existence of extreme market volatility
or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares
trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when
the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount
to the NAV, the shareholder may sustain losses.

Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.

An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.
|
| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality. The following is a description of additional principal risks
of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a
national securities exchange.
|
| Market Trading Risk |
Market Trading
Risk: Active trading markets for the ETF Class shares may not be
developed or maintained by market makers or authorized participants. Authorized participants are not
obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation
units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances.
There can be no assurance that the requirements of the listing exchange necessary to maintain the listing
of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market
for the ETF Class shares may become less liquid in response to deteriorating
liquidity in the markets for the fund’s portfolio holdings, which may cause

|
| Small and Mid-Cap Company Risk |
Small
and Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Risks of Concentrating in the Real Estate Industry |
Risks of Concentrating
in the Real Estate Industry: A fund that concentrates
(i.e., invests more than 25% of its net assets) its investments in securities of companies in the real
estate industry will be exposed to the general risks of direct real estate ownership. The value of securities
in the real estate industry can be affected by changes in real estate values and rental income, property
taxes, and tax and regulatory requirements. Also, the value of securities in the real estate industry
may decline with changes in interest rates. Investing in REITs and REIT-like entities involves certain
unique risks in addition to those risks associated with investing in the real estate industry in general.
REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject
to heavy cash flow dependency and self-liquidation. REITs and REIT-like entities also are subject to
the possibility of failing to qualify for tax free pass-through of income. Also, because REITs and REIT-like
entities typically are invested in a limited number of projects or in a particular market segment, these
entities are more susceptible to adverse developments affecting a single project or market segment than
more broadly diversified investments. The performance of a fund may be materially different from the
broad equity market.

a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.

Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to

Risk: Even a long-term investment approach cannot guarantee a profit.
Economic, market, environmental, political, and issuer-specific conditions and events will cause the
value of equity securities, and a
fund that owns them, to rise or fall. Stock markets are volatile, with periods
of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign
Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio hedges foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Derivatives Risk |
Derivatives Risk:
Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency
forward contracts, whose value is derived from that of other assets, rates or indices. Derivatives can
be used for hedging (attempting to reduce risk by offsetting one investment position with another) or
non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that
a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate
gains or cause losses if the market moves in a manner different from that anticipated by a fund or if
the cost of the derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally
not possible to precisely match the foreign currency exposure of such foreign currency forward contracts
to the value of the securities involved due to fluctuations in the market values of such securities and
cash flows into and out of a fund between the date a foreign currency forward contract is entered into
and the date it expires. The use of derivatives for non-hedging purposes may be considered to carry more
risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed
to the risks of those derivatives. Derivative instruments are subject to a number of risks including
counterparty, settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties
with respect to valuation. Changes in the value of a derivative may not correlate perfectly with the
underlying asset, rate or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among other
reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments at opportune
prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by a
fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market developments.
Liquidity risk includes the risk that a fund will experience significant net redemptions at a time when
it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities
at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market
turmoil or in situations where ownership of shares of a fund are concentrated in one or a few investors.
Investments that are illiquid or that trade in lower volumes may be more difficult to value.

| Operational Risk |
Operational Risk: Operational risks include
human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”). Various
operational events or circumstances are outside a fund’s or its advisor’s control, including instances
at third parties. A fund and its advisor seek to reduce these operational risks through controls and
procedures. However, measures that seek to reduce these operational risks through controls and procedures
may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential risks
linked to cyber security breaches of those technological or information systems. Cyber security breaches,
amongst other things, could allow an unauthorized party to gain access to proprietary information, customer
data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose
operational functionality.

Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a
fund that owns them, to rise or fall. Stock markets are volatile, with periods
of rising prices and periods of falling prices.
|
| Value Investment Risk |
Value Investment
Risk: Value stocks may perform differently from the market as a
whole and an investment strategy purchasing these securities may cause a fund to at times underperform
equity funds that use other investment strategies. Value stocks can react differently to political, economic,
and industry developments than the market as a whole and other types of stocks. Value stocks also may
underperform the market for long periods of time.
|
| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s or
its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce
these operational risks through controls and procedures. However, measures that seek to reduce these

markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than
with respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.

|
| Small and Mid-Cap Company Risk |
Small and
Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Profitability Investment Risk |
Profitability

An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds Risk:
The investment performance of a fund of funds is affected by the investment performance
of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve
its investment objective depends on the ability of the underlying funds to meet their investment objectives
and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among
the underlying funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms
other funds or asset classes. There can be no assurance that the investment objective of a fund of funds
or any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are
principal risks of investing in the Portfolio are described below.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be
forced to convert, its currency to another currency, changing its value against the U.S. dollar). The
Underlying Funds do not hedge foreign currency risk. Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts. Depositary receipts are generally subject
to the same risks as the foreign securities that they evidence or into which they may be converted. In
addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| Small Company Risk |
Small Company Risk: Securities of small companies
are often less liquid than those of large companies and this could make it difficult to sell a small
company security at a desired time or price. As a result, small company stocks may fluctuate relatively
more in price. In general, smaller capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.

of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Series does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.
|
| Geographic Focus Risk |
Geographic
Focus Risk: If a fund focuses its investments
in securities of issuers located in a particular country or region, the fund may be subjected, to a greater
extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;
adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other
developments; or natural disasters.
|
| Japan Market Risk |
Japan Market
Risk: The performance of a fund that concentrates investments in
Japan is expected to be closely tied to the social, political and economic conditions within Japan and
to be more volatile than the performance of funds with more geographically diverse investments.
|
| Small Company Risk |
Small Company Risk: Securities of small companies
are often less liquid than those of large companies and this could make it difficult to sell a small
company security at a desired time or price. As a result, small company stocks may fluctuate relatively
more in price. In general, smaller capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as
well as difficulties with respect to valuation. Changes in the value of a derivative
may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than
the principal amount invested.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Operational Risk |
Operational Risk: Operational risks include
human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.

extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;
adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other
developments; or natural disasters.
|
| Small and Mid-Cap Company Risk |
Small and
Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Risks of Concentrating in the Real Estate Industry |
Risks of Concentrating
in the Real Estate Industry: A fund that concentrates
(i.e., invests more than 25% of its net assets) its investments in securities of companies in the real
estate industry will be exposed to the general risks of direct real estate ownership. The value of securities
in the real estate industry can be affected by changes in real estate values and rental income, property
taxes, and tax and regulatory requirements. Also, the value of securities in the real estate industry
may decline with changes in interest rates. Investing in REITs and REIT-like entities involves certain
unique risks in addition to those risks associated with investing in the real estate industry in general.
REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject
to heavy cash flow dependency and self-liquidation. REITs and REIT-like entities also are subject to
the possibility of failing to qualify for tax free pass-through of income. Also, many foreign REIT-like
entities are deemed for tax purposes as passive foreign investment companies (PFICs), which could result
in the receipt of taxable dividends to shareholders at an unfavorable tax rate. Also, because REITs and
REIT-like entities typically are invested in a limited number of projects or in a particular market segment,
these entities are more susceptible to adverse developments affecting a single project or market segment
than more broadly diversified investments. The performance of a fund may be materially different from
the broad equity market.
|
| Emerging Markets Risk |
Emerging Markets Risk:
Securities of issuers associated with emerging market countries may be subject
to higher and additional risks than securities of issuers in developed foreign markets. Numerous
emerging market countries have a history of, and continue to experience serious, and potentially continuing,
economic and political problems. Stock markets in many emerging market countries are relatively small,
expensive to trade in and generally have higher risks than those in developed markets. Securities in
emerging markets also may be less liquid than those in developed markets and foreigners are often limited
in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be
imposed under other conditions. Frontier market countries generally have smaller economies or less developed
capital markets and, as a result, the risks of investing in emerging market countries are magnified in
frontier market countries.

A fund could also lose money if it does not recover the securities and/or the value of the collateral
falls, including the value of investments made with cash collateral. Securities lending also may have
certain adverse tax consequences.

Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.

| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.

| Risk Lose Money [Member] |
Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds Risk:
The investment performance of a fund of funds is affected by the investment performance
of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve
its investment objective depends on the ability of the underlying funds to meet their investment objectives
and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among
the underlying funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms
other funds or asset classes. There can be no assurance that the investment objective of a fund of funds
or any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are
principal risks of investing in the Portfolio are described below.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Underlying Funds do not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
|
| Small and Mid-Cap Company Risk |
Small and
Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Risks of Concentrating in the Real Estate Industry |
Risks of Concentrating
in the Real Estate Industry: A fund that concentrates
(i.e., invests more than 25% of its net assets) its investments in securities of companies in the real
estate industry will be exposed to the general risks of direct real estate ownership. The value of securities
in the real estate industry can be affected by changes in real estate values and rental income, property
taxes, and tax and regulatory requirements. Also, the value of securities in the real estate industry
may decline with changes in interest rates. Investing in REITs and REIT-like entities involves certain
unique risks in addition to those risks associated with investing in the real estate industry in general.
REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject
to heavy cash flow dependency and self-liquidation. REITs and REIT-like entities also are subject to
the possibility of failing to qualify for tax free pass-through of income. Also, many foreign REIT-like
entities are deemed for tax purposes as passive foreign investment companies (PFICs), which could result
in the receipt of taxable dividends to shareholders at an unfavorable tax rate. Also, because REITs and
REIT-like entities typically are invested in a limited number of projects or in a particular market segment,
these entities are more susceptible to adverse developments affecting a single project or market segment
than more broadly diversified investments. The performance of a fund may be materially different from
the broad equity market.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities
of issuers associated with emerging market countries may be subject to higher and additional risks than
securities of issuers in developed foreign markets. Numerous emerging market
countries have a history of, and continue to experience serious, and potentially continuing, economic
and political problems. Stock markets in many emerging market countries are relatively small, expensive
to trade in and generally have higher risks than those in developed markets. Securities in emerging markets
also may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| Derivatives Risk |
Derivatives Risk:
Derivatives are instruments, such as futures contracts, and options thereon, and foreign currency forward
contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, settlement, liquidity, interest
rate, market, credit and management risks, as well as difficulties with respect to valuation. Changes
in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and
a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,

respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.
|
| Geographic Focus Risk |
Geographic
Focus Risk: If a fund focuses its investments
in securities of issuers located in a particular country or region, the fund may be subjected, to a greater
extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;
adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other
developments; or natural disasters.
|
| Value Investment Risk |
Value Investment
Risk: Value stocks may perform differently from the market as a
whole and an investment strategy purchasing these securities may cause a fund to at times underperform
equity funds that use other investment strategies. Value stocks can react differently to political, economic,
and industry developments than the market as a whole and other types of stocks. Value stocks also may
underperform the market for long periods of time.

|
| Fund of Funds Risk |
Fund of Funds Risk:
The investment performance of a fund of funds is affected by the investment performance
of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve
its investment objective depends on the ability of the underlying funds to meet their investment objectives
and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among
the underlying funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms
other funds or asset classes. There can be no assurance that the investment objective of a fund of funds
or any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are
principal risks of investing in the Portfolio are described below.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Underlying Funds do not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally subject to the same risks as the foreign securities

|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities
of small and mid-cap companies are often less liquid than those of large companies and this could make
it difficult to sell a small or mid-cap company security at a desired time or price. As a result, small
and mid-cap company stocks may fluctuate relatively more in price. In general, small and mid-capitalization
companies are also more vulnerable than larger companies to adverse business or economic developments
and they may have more limited resources.
|
| Value Investment Risk |
Value
Investment Risk: Value stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies. Value stocks can react differently
to political, economic, and industry developments than the market as a whole and other types of stocks.
Value stocks also may underperform the market for long periods of time.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.

| China Investments Risk |
China Investments Risk:
There are special risks associated with investments in China, Hong Kong, and Taiwan.
China, Hong Kong, and Taiwan are highly interconnected and interdependent, with relationships built on
trade, finance, culture, and politics. Despite prior economic and trade reforms and the prior expansion
of private ownership of companies in certain sectors, the Chinese government still exercises substantial
influence over many aspects of the private sector and may own or control many companies, including by
embedding Chinese Communist Party or People’s Armed Forces Department personnel in Chinese companies.
In addition, the Chinese government continues to maintain a major role in economic policy making and
may alter or discontinue economic or trade reforms at any time. Investing in China involves risks of
losses due to expropriation, nationalization, confiscation of assets and property, and the imposition
of restrictions on foreign investments and on repatriation of capital invested. Investments
in China, Hong Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating
relations with the U.S. as economic and strategic competition between the U.S. and China intensifies,
which could result in further tariffs, trade restrictions, sanctions, or other actions that adversely
impact the value of such investments. A reduction in spending on Chinese products and services, supply
chain diversification or the institution of additional tariffs or other trade barriers, including as
a result of heightened trade tensions between China and the United States may also have an adverse impact
on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political
and economic relationship with China. Certain securities issued by companies located or operating in
China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market
liquidity, which could pose risks to a fund investing in such securities. In addition, investments in
special structures that utilize contractual arrangements to provide exposure to certain Chinese companies,
known as variable interest entities (“VIEs”), that operate in sectors in which China restricts
and/or prohibits foreign investments may present additional risks. The Chinese government’s acceptance
of the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw
their acceptance of the structure generally, or with respect to certain industries, or whether Chinese
courts or arbitration bodies would decline to enforce the contractual rights of foreign investors, each of which
would likely have significant, detrimental, and possibly permanent losses on the value of such investments.

| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

|
Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your

| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.
|
| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry
developments than the market as a whole and other types of stocks. Value stocks also may underperform
the market for long periods of time.
|
| Small and Mid-Cap Company Risk |
Small and
Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Foreign Securities and Currencies Risk |
Foreign Securities
and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.

|
| Fund of Funds Risk |
Fund of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding
the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate
assets to an underlying fund or asset class that underperforms other funds or asset classes. There can
be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved.
Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying
funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to
a proportionate share of the expenses of those underlying funds in addition to the expenses of a fund
of funds. Certain risks of the Underlying Funds’ investments that are principal risks of investing
in the Portfolio are described below.

but the Portfolio may directly hedge the foreign currency risk it is exposed to through its investment

some or all of its foreign currency exposure unhedged. Currencies may be hedged against the U.S. dollar
or non-U.S. dollar currencies. Foreign issuers may not be subject to
uniform accounting, auditing and financial reporting standards and there may be less reliable and publicly
available financial and other information about such issuers, as compared to U.S. issuers. A fund may

| Derivatives Risk |
Derivatives Risk:
Derivatives are instruments, such as futures contracts, and options thereon, and foreign currency forward
contracts, whose value is derived from that of other assets, rates or indices. Derivatives can be used
for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging
purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy
will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause
losses if the market moves in a manner different from that anticipated by a fund or if the cost of the
derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally not possible
to precisely match the foreign currency exposure of such foreign currency forward contracts to the value
of the securities involved due to fluctuations in the market values of such securities and cash flows
into and out of a fund between the date a foreign currency forward contract is entered into and the date
it expires. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties with
respect to valuation. Changes in the value of a derivative may not correlate perfectly with the underlying

extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;
adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other
developments; or natural disasters.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| China Investments Risk |
China Investments Risk: There are special risks
associated with investments in China, Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly
interconnected and interdependent, with relationships built on trade, finance, culture, and politics.
Despite prior economic and trade reforms and the prior expansion of private ownership of companies in
certain sectors, the Chinese government still exercises substantial influence over many aspects of the
private sector and may own or control many companies, including by embedding Chinese Communist Party
or People’s Armed Forces Department personnel in Chinese companies. In addition, the Chinese government
continues to maintain a major role in economic policy making and may alter or discontinue economic or
trade reforms at any time. Investing in China involves risks of losses due to expropriation, nationalization,
confiscation of assets and property, and the imposition of restrictions on foreign investments and on
repatriation of capital invested. Investments in China, Hong
Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with
the U.S. as economic and strategic competition between the U.S. and China intensifies, which could result
in further tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of
such investments. A reduction in spending on Chinese products and services, supply
chain diversification or the institution of additional tariffs or other trade barriers, including as
a result of heightened trade tensions between China and the United States may also have an adverse impact
on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political
and economic relationship with China. Certain securities issued by companies located or operating in
China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market
liquidity, which could pose risks to a fund investing in such securities. In addition, investments in
special structures that utilize contractual arrangements to provide exposure to certain Chinese companies,
known as variable interest entities (“VIEs”), that operate in sectors in which China restricts
and/or prohibits foreign investments may present additional risks. The Chinese government’s acceptance
of the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw
their acceptance of the structure generally, or with respect to certain industries, or whether Chinese
courts or arbitration bodies would decline to enforce the contractual rights of foreign investors, each
of which would likely have significant, detrimental, and possibly permanent losses on the value of such
investments.

| Profitability Investment Risk |
Profitability Investment Risk: High
relative profitability stocks may perform differently from the market as a whole and an investment strategy
purchasing these securities may cause a fund to at times underperform equity funds that use other investment
strategies.
|
| Value Investment Risk |
Value Investment Risk:
Value stocks may perform differently from the market as a whole and an investment
strategy purchasing these securities may cause a fund to at times underperform equity funds that use
other investment strategies. Value stocks can react differently to political, economic, and industry
developments than the market as a whole and other types of stocks. Value stocks also may underperform
the market for long periods of time.
|
| Derivatives Risk |
Derivatives
Risk: Derivatives are instruments, such as futures contracts, and options thereon,
and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices.
The use of derivatives for non-hedging purposes may be considered to carry more risk than other types
of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those
derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.

An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities
and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Series does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.
|
| Geographic Focus Risk |
Geographic
Focus Risk: If a fund focuses its investments
in securities of issuers located in a particular country or region, the fund may be subjected, to a greater
extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;

bodies would decline to enforce the contractual rights of foreign investors, each of which would likely
have significant, detrimental, and possibly permanent losses on the value of such investments.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Value Investment Risk |
Value Investment
Risk: Value stocks may perform differently from the market as a
whole and an investment strategy purchasing these securities may cause a fund to at times underperform
equity funds that use other investment strategies. Value stocks can react differently to political, economic,

| Small Company Risk |
Small Company
Risk: Securities of small companies are often less liquid than those of large companies
and this could make it difficult to sell a small company security at a desired time or price. As a result,
small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they

in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability to invest
in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions.
Frontier market countries generally have smaller economies or less developed capital markets and, as
a result, the risks of investing in emerging market countries are magnified in frontier market countries.
|
| China Investments Risk |
China Investments Risk: There are special risks
associated with investments in China, Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly
interconnected and interdependent, with relationships built on trade, finance, culture, and politics.
Despite prior economic and trade reforms and the prior expansion of private ownership of companies in
certain sectors, the Chinese government still exercises substantial influence over many aspects of the
private sector and may own or control many companies, including by embedding Chinese Communist Party
or People’s Armed Forces Department personnel in Chinese companies. In addition, the Chinese government
continues to maintain a major role in economic policy making and may alter or discontinue economic or
trade reforms at any time. Investing in China involves risks of losses due to expropriation, nationalization,
confiscation of assets and property, and the imposition of restrictions on foreign investments and on
repatriation of capital invested. Investments in China, Hong
Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with
the U.S. as economic and strategic competition between the U.S. and China intensifies, which could result
in further tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of
such investments. A reduction in spending on Chinese products and services, supply chain diversification
or the institution of additional tariffs or other trade barriers, including as a result of heightened
trade tensions between China and the United States may also have an adverse impact on the Chinese economy.
In addition, investments in Taiwan could be adversely affected by its political and economic relationship
with China. Certain securities issued by companies located or operating in China, such as China A-shares,
are also subject to trading restrictions, quota limitations and less market liquidity, which could pose
risks to a fund investing in such securities. In addition, investments in special structures that utilize
contractual arrangements to provide exposure to certain Chinese companies, known as variable interest
entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign
investments may present additional risks. The Chinese government’s acceptance of the VIE structure
is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance
of the structure generally, or with respect to certain industries, or whether Chinese courts or arbitration
bodies would decline to enforce the contractual rights of foreign investors, each of which would likely
have significant, detrimental, and possibly permanent losses on the value of such investments.

Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or its service
providers to suffer data corruption or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis,
pursuing legal remedies, and obtaining judgments with respect to foreign investments in foreign courts
than with respect to domestic issuers in U.S. courts. Depositary receipts are
generally subject to the same risks as the foreign securities that they evidence or into which they may
be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored
or unregistered depositary receipts, are under no obligation to distribute shareholder communications
to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited
securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may
be less readily available public information about the issuer.
|
| Geographic Focus Risk |
Geographic
Focus Risk: If a fund focuses its investments
in securities of issuers located in a particular country or region, the fund may be subjected, to a greater
extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;
adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other
developments; or natural disasters.
|
| Small and Mid-Cap Company Risk |
Small and
Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| China Investments Risk |
China Investments Risk: There are special risks
associated with investments in China, Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly
interconnected and interdependent, with relationships built on trade, finance, culture, and politics.
Despite prior economic and trade reforms and the prior expansion of private ownership of companies in
certain sectors, the Chinese government still exercises substantial influence over many aspects of the
private sector and may own or control many companies, including by embedding Chinese Communist Party
or People’s Armed Forces Department personnel in Chinese companies. In addition, the Chinese government
continues to maintain a major role in economic policy making and may alter or discontinue economic or
trade reforms at any time. Investing in China involves risks of losses due to expropriation, nationalization,
confiscation of assets and property, and the imposition of restrictions on foreign investments and on
repatriation of capital invested. Investments in China, Hong
Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with
the U.S. as economic and strategic competition between the U.S. and China intensifies, which could result
in further tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of
such investments. A reduction in spending on Chinese products and services, supply chain diversification
or the institution of additional tariffs or other trade barriers, including as a result of heightened
trade tensions between China and the United States may also have an adverse impact on the Chinese economy.
In addition, investments in Taiwan could be adversely affected by its political and economic relationship
with China. Certain securities issued by companies located or operating in China, such as China A-shares,
are also subject to trading restrictions, quota limitations and less market liquidity, which could pose
risks to a fund investing in such securities. In addition, investments in special structures that utilize
contractual arrangements to provide exposure to certain Chinese companies, known as variable interest
entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign
investments may present additional risks. The Chinese government’s acceptance of the VIE structure
is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance
of the structure generally, or with respect to certain industries, or whether Chinese courts or arbitration
bodies would decline to enforce the contractual rights of foreign investors, each of which
would likely have significant, detrimental, and possibly permanent losses on the value of such investments.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

|
| Taiwan Investments Risk |
Taiwan Investments
Risk: There are special risks associated with investments in Taiwan. Taiwan and China
are highly interconnected and interdependent, with relationships and tensions built on trade, finance,
culture, and politics. Taiwan’s political stability and ability to sustain its economic growth
could be significantly affected by its political and economic relationship with China and Taiwan remains
vulnerable to both Chinese territorial ambitions and economic downturns. The economic success of China
will continue to have an outsized influence on the growth and prosperity of Taiwan.
|

remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Interest Rate Risk |
Interest Rate Risk:
Fixed income securities are subject to interest rate risk because the prices of
fixed income securities tend to move in the opposite direction of interest rates. When interest rates
rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund
may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security
prices rise. In general, fixed income securities with longer maturities are more sensitive to changes
in interest rates.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such
securities. Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that
are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities
sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from
the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Derivatives Risk |
Derivatives Risk: Derivatives
are instruments, such as futures contracts, and options thereon, whose value is derived from that of
other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting
one investment position with another) or non-hedging purposes. Hedging with derivatives may increase
expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate
losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different
from that anticipated by a fund or if the cost of the derivative outweighs the benefit of the hedge.
The use of derivatives for non-hedging purposes may be considered to carry more risk than other types
of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those
derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.

Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is

to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk: Securities
lending involves the risk that the borrower may fail to return the securities in a timely manner or at
all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities.
A fund could also lose money if it does not recover the securities and/or the value of the collateral
falls, including the value of investments made with cash collateral. Securities lending also may have
certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Risk [Text Block] |
| Principal Risks |
Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio may hedge the currency exposure of its foreign
securities or leave some or all of the currency exposure unhedged. Foreign issuers may not be subject to uniform accounting, auditing and financial
reporting standards and there may be less reliable and publicly available financial and other information
about such issuers, as compared to U.S. issuers. A fund may have greater difficulty voting proxies, exercising
shareholder rights, securing dividends and/or interest and obtaining information regarding corporate
actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments
in foreign courts than with respect to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government Debt Risk: The
risk that: (a) the governmental entity that controls the repayment of government debt may not be willing
or able to repay the principal and/or to pay the interest when it becomes due, due to factors such as
political considerations, the relative size of the governmental entity’s debt position in relation
to the economy, cash flow problems, insufficient foreign currency reserves, the failure to put in place
economic reforms required by the International Monetary Fund or other multilateral agencies, and/or other
national economic factors; (b) governments may default on their debt securities, which may require holders
of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy process
by which defaulted government debt may be collected in whole or in part.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.

| Liquidity Risk |
Liquidity Risk: Liquidity
risk exists when particular portfolio investments are difficult to purchase or sell. To the extent that
a fund holds illiquid investments, the fund’s performance may be reduced due to an inability to
sell the investments at opportune prices or times. Liquid portfolio investments may become illiquid or
less liquid after purchase by a fund due to low trading volume, adverse investor perceptions, credit
tightening and/or other market developments. Liquidity risk includes the risk that a fund will experience
significant net redemptions at a time when it cannot find willing buyers for its portfolio securities
or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can
be more pronounced in periods of market turmoil or in situations where ownership of shares of a fund
are concentrated in one or a few investors. Investments that are illiquid or that trade in lower volumes
may be more difficult to value.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Operational Risk |
Operational Risk: Operational risks include
human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

|
| Geographic Focus Risk |
Geographic
Focus Risk: If a fund focuses its investments
in securities of issuers located in a particular country or region, the fund may be subjected, to a greater
extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such
|
| as |
as: adverse securities markets; adverse exchange rates; adverse social, political,
regulatory, economic, business, environmental or other developments; or natural disasters.

|
| Non-Diversification Risk |
Non-Diversification Risk: The risk that a fund may
be more volatile than a diversified fund because a fund invests its assets in a smaller number of issuers.
The gains or losses on a single security, therefore, may have a greater impact on a fund’s net
asset value.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial

or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can
be more pronounced in periods of market turmoil or in situations where ownership of shares of a fund

lower-yielding securities.
|
| Liquidity Risk |
Liquidity
Risk: Liquidity risk exists when particular portfolio investments
are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund’s
performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions, credit tightening and/or other market developments. Liquidity risk
includes the risk that a fund will experience significant net redemptions at a time when it cannot find
willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss
or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations
where ownership of shares of a fund are concentrated in one or a few investors. Investments that are
illiquid or that trade in lower volumes may be more difficult to value.
|
| Derivatives Risk |
Derivatives Risk: Derivatives
are instruments, such as futures contracts, and options thereon, whose value is derived from that of
other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting
one investment position with another) or non-hedging purposes. Hedging with derivatives may increase
expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate
losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different
from that anticipated by a fund or if the cost of the derivative outweighs the benefit of the hedge.
The use of derivatives for non-hedging purposes may be considered to carry more risk than other types
of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those
derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not

|
| Market Risk |
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite

Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies
Risk: Foreign securities prices may decline or fluctuate because
of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities
markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility
that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will
convert, or be forced to convert, its currency to another currency, changing its value against the U.S.
dollar). The Portfolio hedges foreign currency risk. Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies, and/or
other national economic factors; (b) governments may default on their debt securities, which may require
holders of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy
process by which defaulted government debt may be collected in whole or in part.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with

risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when
it cannot find willing buyers for its portfolio securities or can only sell its
portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced
in periods of market turmoil or in situations where ownership of shares of a fund are concentrated in
one or a few investors. Investments that are illiquid or that trade in lower volumes may be more difficult
to value.

Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the

that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.

Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational

Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.

| Foreign Government Debt Risk |
Foreign
Government Debt Risk: The risk that: (a) the
governmental entity that controls the repayment of government debt may not be willing or able to repay
the principal and/or to pay the interest when it becomes due, due to factors such as political considerations,
the relative size of the governmental entity’s debt position in relation to the economy, cash flow

|
| Interest Rate Risk |
Interest
Rate Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security may be unable to make interest
payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived
change in an issuer’s financial strength may affect a security’s value, and thus, impact
the performance of a fund holding such securities. Government agency obligations have different levels
of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and
instrumentalities of the U.S. Government that are supported by the full faith and credit of the United
States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other
securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported
only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limitations, and
securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored
by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree
of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may
still involve a risk of non-payment of principal and/or interest.
|
| High Yield Risk |
High Yield Risk: Securities rated below
investment grade may be subject to greater credit, valuation, price volatility, and liquidity risks than
investment grade securities. Fixed income securities that are below investment grade involve high credit
risk and are considered speculative. Below investment grade fixed income securities may also fluctuate
in value more than higher quality fixed income securities and, during periods of market volatility, may
be more difficult to sell at the time and price a fund desires.
|
| Income Risk |
Income Risk: Income risk is the risk
that falling interest rates will cause a fund’s income to decline because, among other reasons,
the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate
or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value.
|
| Liquidity Risk |
Liquidity Risk:
Liquidity risk exists when particular portfolio investments are difficult to purchase
or sell. To the extent that a fund holds illiquid investments, the fund’s performance may be reduced
due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that
a fund will experience significant net redemptions at a time when it cannot find willing buyers for its
portfolio securities or can only sell its portfolio securities at a material loss or at increased costs.
Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of
shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade
in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Operational Risk |
Operational Risk: Operational risks include
human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies
Risk: Foreign securities prices may decline or fluctuate because
of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities
markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility
that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will
convert, or be forced to convert, its currency to another currency, changing its value against the U.S.
dollar). The Portfolio hedges foreign currency risk. Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Emerging Markets Risk |
Emerging Markets Risk:
Securities of issuers associated with emerging market countries may be subject
to higher and additional risks than securities of issuers in developed foreign markets. Numerous
emerging market countries have a history of, and continue to experience serious, and potentially continuing,
economic and political problems. Stock markets in many emerging market countries are relatively small,
expensive to trade in and generally have higher risks than those in developed markets. Securities in
emerging markets also may be less liquid than those in developed markets and foreigners are often limited
in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be
imposed under other conditions. Frontier market countries generally have smaller economies or less developed
capital markets and, as a result, the risks of investing in emerging market countries are magnified in
frontier market countries.
|
| China Investments Risk |
China Investments
Risk: There are special risks associated with investments in China,
Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly interconnected and interdependent, with
relationships built on trade, finance, culture, and politics. Despite prior economic and trade reforms
and the prior expansion of private ownership of companies in certain sectors, the Chinese government
still exercises substantial influence over many aspects of the private sector and may own or control
many companies, including by embedding Chinese Communist Party or People’s Armed Forces Department
personnel in Chinese companies. In addition, the Chinese government continues to maintain a major role
in economic policy making and may alter or discontinue economic or trade reforms at any time. Investing
in China involves risks of losses due to expropriation, nationalization, confiscation of assets and property,
and the imposition of restrictions on foreign investments and on repatriation of capital invested. Investments
in China, Hong Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating
relations with the U.S. as economic and strategic competition between the U.S. and China intensifies,
which could result in further tariffs, trade restrictions, sanctions, or other actions that adversely
impact the value of such investments. A reduction in spending on Chinese products and services, supply
chain diversification or the institution of additional tariffs or other trade barriers, including as
a result of heightened trade tensions between China and the United States may also have an adverse impact
on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political
and economic relationship with China.
|
| Mortgage-Backed Securities Risk |
Mortgage-Backed
Securities Risk: Mortgage-backed securities
represent interests in “pools” of mortgages and often involve risks that are different from
or potentially more significant than risks associated with other types of debt instruments. Mortgage
securities differ from typical debt securities in that principal is not paid back at maturity, but rather
periodically over the life of the security. A fund may receive unscheduled payments of principal due
to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. When interest
rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns
of a fund because it may have to reinvest that money at the lower prevailing interest rates. As a result,
mortgage securities may be less effective than some other types of debt securities as a means of securing
long-term interest rates and may have less potential for capital appreciation during periods of falling
interest rates. Conversely, in a period of rising interest rates, a fund may exhibit additional volatility
since rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making
them more sensitive to changes in interest rates. As interest rates rise mortgage borrowers are less
likely to exercise prepayment options, which may reduce the value of these securities and potentially
cause a fund to lose money. This is known as extension risk.
|
| Interest Rate Risk |
Interest
Rate Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security may be unable to make interest
payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived
change in an issuer’s financial strength may affect a security’s value, and thus, impact
the performance of a fund holding such securities. Government agency obligations have different levels
of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and
instrumentalities of the U.S. Government that are supported by the full faith and credit of the United
States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other
securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported
only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limitations, and
securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored
by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree
of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may
still involve a risk of non-payment of principal and/or interest. Credit risk is greater for fixed income
securities with ratings below investment grade (e.g., BB+ or below by S&P or Fitch or Ba1 or below
by Moody’s). Fixed income securities that are below investment grade involve high credit risk and
are considered speculative. Below investment grade fixed income securities may also fluctuate in value
more than higher quality fixed income securities and, during periods of market volatility, may be more
difficult to sell at the time and price the Portfolio desires.
|
| High Yield Risk |
High Yield Risk: Securities rated below
investment grade may be subject to greater credit, valuation, price volatility, and liquidity risks than
investment grade securities. Fixed income securities that are below investment grade involve high credit
risk and are considered speculative. Below investment grade fixed income securities may also fluctuate
in value more than higher quality fixed income securities and, during periods of market volatility, may
be more difficult to sell at the time and price a fund desires.
|
| Income Risk |
Income Risk: Income risk is the risk
that falling interest rates will cause a fund’s income to decline because, among other reasons,
the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be
used for hedging (attempting to reduce risk by offsetting one investment position
with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no
guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. In regard to currency
hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign
currency forward contracts to the value of the securities involved due to fluctuations in the market
values of such securities and cash flows into and out of a fund between the date a foreign currency forward
contract is entered into and the date it expires. The use of derivatives for non-hedging purposes may
be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund
will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number
of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested. Additional risks are associated with the use of swaps including counterparty and credit
risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations,
whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary
market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty
risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it
may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations.
Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity
Risk: Liquidity risk exists when particular portfolio investments
are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund’s
performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions, credit tightening and/or other market developments. Liquidity risk
includes the risk that a fund will experience significant net redemptions at a time when it cannot find
willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss
or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations
where ownership of shares of a fund are concentrated in one or a few investors. Investments that are
illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

|
| Fund of Funds Risk |
Fund of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding
the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate
assets to an underlying fund or asset class that underperforms other funds or asset classes. There can
be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved.
Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying
funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to
a proportionate share of the expenses of those underlying funds in addition to the expenses of a fund
of funds. Certain risks of the Underlying Funds’ investments that are principal risks of investing
in the Portfolio are described below.

portfolio securities or can only sell its portfolio securities at a material loss or at increased costs.
Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of
shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade
in lower volumes may be more difficult to value.

| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected
Securities Interest Rate Risk: Inflation-protected securities
may react differently from other fixed income securities to changes in interest rates. Because interest
rates on inflation-protected securities are adjusted for inflation, the values of these securities are
not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities
Tax Risk: Any increase in the principal amount of an inflation-protected
security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital, which could increase or decrease a fund’s ordinary income distributions
to shareholders, and may cause some of a fund’s distributed income to be classified as a return
of capital.
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection:
Because the interest and/or principal payments on an inflation-protected security
are adjusted periodically for changes in inflation, the income distributed by a fund investing in such
securities may be irregular. Although the U.S. Treasury guarantees to pay at maturity at least the original
face value of any inflation-protected securities the Treasury issues, other issuers may not offer the
same guarantee. Inflation-protected securities are not protected against deflation. As a result, in a
period of deflation, the principal and income of inflation-protected securities held by a fund will decline
and the fund may suffer a loss during such periods. While inflation-protected securities are expected
to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline
in the value of a fund holding such securities. For example, if interest rates rise due to reasons other
than inflation, a fund’s investment in these securities may not be protected to the extent that
the increase is not reflected in the securities’ inflation measures. In addition, positive adjustments
to principal generally will result in taxable income to a fund at the time of such adjustments (which
generally would be distributed by the fund as part of its taxable dividends), even though the principal
amount is not paid until maturity. The current market value of inflation-protected securities is not
guaranteed and will fluctuate.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security may be unable to make interest
payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived
change in an issuer’s financial strength may affect a security’s value, and thus, impact
the performance of a fund holding such securities. Government agency obligations have different levels
of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and
instrumentalities of the U.S. Government that are supported by the full faith and credit of the United
States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other
securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported
only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limitations, and
securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored
by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree
of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may
still involve a risk of non-payment of principal and/or interest.
|
| Income Risk |
Income Risk: Income risk is the risk
that falling interest rates will cause a fund’s income to decline because, among other reasons,
the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine
learning (“AI”). Various operational events or circumstances are outside
a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor
seek to reduce these operational risks through controls and procedures. However, measures that seek to
reduce these operational risks through controls and procedures may not address every possible risk and
may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not

|
| Market Risk |
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.

a fund’s income to decline because, among other reasons, the proceeds from maturing short-term
securities in its portfolio may be reinvested in lower-yielding securities.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio hedges foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Derivatives Risk |
Derivatives Risk:
Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency
forward contracts, whose value is derived from that of other assets, rates or indices. Derivatives can
be used for hedging (attempting to reduce risk by offsetting one investment position with another) or
non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that
a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate
gains or cause losses if the market moves in a manner different from that anticipated by a fund or if
the cost of the derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally
not possible to precisely match the foreign currency exposure of such foreign currency forward contracts
to the value of the securities involved due to fluctuations in the market values of such securities and
cash flows into and out of a fund between the date a foreign currency forward contract is entered into
and the date it expires. The use of derivatives for non-hedging purposes may be considered to carry more
risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed
to the risks of those derivatives. Derivative instruments are subject to a number of risks including
counterparty, settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties
with respect to valuation. Changes in the value of a derivative may not correlate perfectly with the
underlying asset, rate or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value.

| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.

security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital, which could increase or decrease a fund’s ordinary income distributions
to shareholders, and may cause some of a fund’s distributed income to be classified as a return
of capital.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such
securities. Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that
are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities
sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from
the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest.

| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation
Protection: Because the interest and/or principal payments on an inflation-protected
security are adjusted periodically for changes in inflation, the income distributed by a fund investing
in such securities may be irregular. Although the U.S. Treasury guarantees to pay at maturity at least
the original face value of any inflation-protected securities the Treasury issues, other issuers may
not offer the same guarantee. Inflation-protected securities are not protected against deflation. As
a result, in a period of deflation, the principal and income of inflation-protected securities held by
a fund will decline and the fund may suffer a loss during such periods. While inflation-protected securities
are expected to be protected from long-term inflationary trends, short-term increases in inflation may
lead to a decline in the value of a fund holding such securities. For example, if interest rates rise
due to reasons other than inflation, a fund’s investment in these securities may not be protected
to the extent that the increase is not reflected in the securities’ inflation measures. In addition,
positive adjustments to principal generally will result in taxable income to a fund at the time of such
adjustments (which generally would be distributed by the fund as part of its taxable dividends), even
though the principal amount is not paid until maturity. The current market value of inflation-protected
securities is not guaranteed and will fluctuate.
|
| Income Risk |
Income
Risk: Income risk is the risk that falling interest rates will cause
a fund’s income to decline because, among other reasons, the proceeds from maturing short-term
securities in its portfolio may be reinvested in lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives
are instruments, such as swaps, futures contracts, and options thereon, and foreign currency forward
contracts, whose value is derived from that of other assets, rates or indices. Derivatives can be used
for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging
purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy
will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause
losses if the market moves in a manner different from that anticipated by a fund or if the cost of the
derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally not possible
to precisely match the foreign currency exposure of such foreign currency forward contracts to the value
of the securities involved due to fluctuations in the market values of such securities and cash flows
into and out of a fund between the date a foreign currency forward contract is entered into and the date
it expires. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties with
respect to valuation. Changes in the value of a derivative may not correlate perfectly with the underlying
asset, rate or index, and a fund could lose more than the principal amount invested. Additional risks
are associated with the use of swaps including counterparty and credit risk (the risk that the other
party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value.
|
| Liquidity Risk |
Liquidity Risk:
Liquidity risk exists when particular portfolio investments are difficult to purchase
or sell. To the extent that a fund holds illiquid investments, the fund’s performance may be reduced
due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that
a fund will experience significant net redemptions at a time when it cannot find willing buyers for its
portfolio securities or can only sell its portfolio securities at a material loss or at increased costs.
Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of
shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade
in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Operational Risk |
Operational Risk: Operational risks include
human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your

|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies
Risk: Foreign securities prices may decline or fluctuate because
of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities
markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility
that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will
convert, or be forced to convert, its currency to another currency, changing its value against the U.S.
dollar). The Portfolio hedges foreign currency risk. Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Emerging Markets Risk |
Emerging Markets Risk:
Securities of issuers associated with emerging market countries may be subject
to higher and additional risks than securities of issuers in developed foreign markets. Numerous
emerging market countries have a history of, and continue to experience serious, and potentially continuing,
economic and political problems. Stock markets in many emerging market countries are relatively small,
expensive to trade in and generally have higher risks than those in developed markets. Securities in
emerging markets also may be less liquid than those in developed markets and foreigners are often limited
in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be
imposed under other conditions. Frontier market countries generally have smaller economies or less developed
capital markets and, as a result, the risks of investing in emerging market countries are magnified in
frontier market countries.
|
| China Investments Risk |
China Investments
Risk: There are special risks associated with investments in China,
Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly interconnected and interdependent, with
relationships built on trade, finance, culture, and politics. Despite prior economic and trade reforms
and the prior expansion of private ownership of companies in certain sectors, the Chinese government
still exercises substantial influence over many aspects of the private sector and may own or control
many companies, including by embedding Chinese Communist Party or People’s Armed Forces Department
personnel in Chinese companies. In addition, the Chinese government continues to maintain a major role
in economic policy making and may alter or discontinue economic or trade reforms at any time. Investing
in China involves risks of losses due to expropriation, nationalization, confiscation of assets and property,
and the imposition of restrictions on foreign investments and on repatriation of capital invested. Investments
in China, Hong Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating
relations with the U.S. as economic and strategic competition between the U.S. and China intensifies,
which could result in further tariffs, trade restrictions, sanctions, or other actions that adversely
impact the value of such investments. A reduction in spending on Chinese products and services, supply
chain diversification or the institution of additional tariffs or other trade barriers, including as
a result of heightened trade tensions between China and the United States may also have an adverse impact
on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political
and economic relationship with China.
|
| Mortgage-Backed Securities Risk |
Mortgage-Backed
Securities Risk: Mortgage-backed securities
represent interests in “pools” of mortgages and often involve risks that are different from
or potentially more significant than risks associated with other types of debt instruments. Mortgage
securities differ from typical debt securities in that principal is not paid back at maturity, but rather
periodically over the life of the security. A fund may receive unscheduled payments of principal due
to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. When interest
rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns
of a fund because it may have to reinvest that money at the lower prevailing interest rates. As a result,
mortgage securities may be less effective than some other types of debt securities as a means of securing
long-term interest rates and may have less potential for capital appreciation during periods of falling
interest rates. Conversely, in a period of rising interest rates, a fund may exhibit additional volatility
since rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making
them more sensitive to changes in interest rates. As interest rates rise mortgage borrowers are less
likely to exercise prepayment options, which may reduce the value of these securities and potentially
cause a fund to lose money. This is known as extension risk.
|
| Interest Rate Risk |
Interest
Rate Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected
Securities Interest Rate Risk: Inflation-protected securities
may react differently from other fixed income securities to changes in interest rates. Because interest
rates on inflation-protected securities are adjusted for inflation, the values of these securities are
not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities
Tax Risk: Any increase in the principal amount of an inflation-protected
security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital, which could increase or decrease a fund’s ordinary income distributions
to shareholders, and may cause some of a fund’s distributed income to be classified as a return
of capital.

be unable to make interest payments and/or repay principal when due. A downgrade to an issuer’s
credit rating or a perceived change in an issuer’s financial strength may affect a security’s value, and thus, impact the performance of a fund
holding such securities. Government agency obligations have different levels of credit support and, therefore,
different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government
that are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities

the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest. Credit risk is greater for fixed income securities with ratings below investment grade
(e.g., BB+ or below by S&P or Fitch or Ba1 or below by Moody’s). Fixed income securities that
are below investment grade involve high credit risk and are considered speculative. Below investment
grade fixed income securities may also fluctuate in value more than higher quality fixed income securities
and, during periods of market volatility, may be more difficult to sell at the time and price the Portfolio
desires.
|
| High Yield Risk |
High Yield Risk:
Securities rated below investment grade may be subject to greater credit, valuation,
price volatility, and liquidity risks than investment grade securities. Fixed income securities that
are below investment grade involve high credit risk and are considered speculative. Below investment
grade fixed income securities may also fluctuate in value more than higher quality fixed income securities
and, during periods of market volatility, may be more difficult to sell at the time and price a fund
desires.

a perceived change in an issuer’s financial strength may affect a security’s value, and thus,
impact the performance of a fund holding such securities. The ability of a municipal securities issuer
to make payments could be affected by litigation, legislation or other political events or the bankruptcy
of the issuer.

fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Tax Liability Risk |
Tax Liability Risk: Tax
liability risk is the risk that distributions by a fund become taxable to shareholders due to noncompliant
conduct by a municipal bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations
of tax laws by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations
or actions could cause interest from a security to become taxable, possibly retroactively, subjecting
shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause
the value of a security, and therefore, the value of a fund’s shares, to decline. Additionally,
if a fund's use of derivative instruments for hedging and non-hedging purposes cause the fund to invest
less than 50% of its assets in municipal securities in any quarter, which a fund does not anticipate,
the fund may fail to qualify to pay exempt-interest dividends to its shareholders, resulting in the distributions
by the fund becoming taxable to shareholders as ordinary income.
|
| Municipal Securities Risk |
Municipal Securities Risk: The risk of a municipal
security generally depends on the financial and credit status of the issuer. Municipal securities can
be significantly affected by political, regulatory or economic changes, including changes made in the
law after issuance of the securities, as well as uncertainties in the municipal market related to taxation,
legislative changes or the rights of municipal security holders, including in connection with an issuer’s
insolvency. The municipal securities market can be susceptible to increases in volatility and decreases
in liquidity. The secondary market for certain municipal securities tends to be less well developed or
liquid than many other securities markets, which may adversely affect a fund's ability to sell such municipal
securities at attractive prices. Liquidity can decline unpredictably in response to overall economic
conditions or credit tightening. In addition, there may be less publicly available information about
the financial condition of municipal security issuers than for issuers of other types of securities,
making the securities more difficult to value. The price a fund could receive upon the sale of a portfolio
investment may differ from the fund’s valuation of the investment, particularly for investments
that trade in thin or volatile markets or that are valued using a fair valuation methodology.
|
| Municipal Project-Specific Risk |
Municipal Project-Specific Risk: A fund
may be more sensitive to adverse economic, business or political developments if it invests a substantial
portion of its assets in municipal securities that finance similar types of projects in a segment of
the municipal bond market (such as education, health care, housing, education, utilities or transportation)
or industrial development bonds. A change that affects one project in a particular segment of the market,
such as proposed legislation on the financing of the project, a shortage of the materials needed for
the project, or a declining need for the project, would likely affect all similar projects, thereby increasing
market risk.
|
| Variable Rate Demand Obligations Risk |
Variable Rate Demand Obligations Risk: Certain
variable rate demand obligations (“VRDOs”) may not have an active
secondary market. These VRDOs could be difficult to dispose of if the remarketing agent defaults on its
payment obligation and/or if the fund is not entitled to exercise its demand rights, which could cause
a loss with respect to such VRDOs.
|
| Derivatives Risk |
Derivatives
Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon,
whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging
(attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes.
Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will
work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses
if the market moves in a manner different from that anticipated by a fund or if the cost of the derivative
outweighs the benefit of the hedge. The use of derivatives for non-hedging purposes may be considered
to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly
exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including
counterparty, liquidity, interest rate, market, credit and management risks, as well as difficulties
with respect to valuation. Changes in the value of a derivative may not correlate perfectly with the
underlying asset, rate or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value. Additionally, payments made or received by a fund under such derivatives may increase
the amount of distributions taxable to you as ordinary income, increase or decrease the amount of capital
gain distributions to you and/or decrease the amount available for distribution to you as exempt-interest
dividends.
|
| High Portfolio Turnover Risk |
High Portfolio Turnover Risk:
When high portfolio turnover (more than 100%) is caused by the sale of a fund’s portfolio securities
and the reinvestment by the fund in other portfolio securities, such high portfolio turnover may
result in increased transaction costs, including brokerage commissions, dealer
mark-ups and other transaction costs. Additionally, the sale of a fund’s portfolio securities may
result in the distribution of higher capital gains as compared to a fund with less active trading policies.
Alternatively, for fixed income funds, a higher portfolio turnover may be in part the result of bonds
being held to their maturity, which may have a minimal impact on transaction costs and taxes.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Operational Risk |
Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description
of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Market Risk |
Market
Risk: Even a long-term investment approach cannot guarantee a profit.
Economic, market, environmental, political, and issuer-specific conditions and events will cause the
value of securities, and a fund that owns them, to rise or fall.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security, including a governmental entity, may be unable to make
interest payments and/or repay principal when due. A downgrade to an issuer’s credit rating or
a perceived change in an issuer’s financial strength may affect a security’s value, and thus,
impact the performance of a fund holding such securities. The ability of a municipal securities issuer
to make payments could be affected by litigation, legislation or other political events or the bankruptcy
of the issuer. Credit risk is greater for fixed income securities with ratings below investment grade
(e.g., BB+ or below by S&P or Fitch or Ba1 or below by Moody’s). Fixed income securities that
are below investment grade involve high credit risk and are considered speculative. Below investment
grade fixed income securities may also fluctuate in value more than higher quality fixed income securities
and, during periods of market volatility, may be more difficult to sell at the time and price the Portfolio
desires.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities
Tax Risk: Any increase in the principal amount of an inflation-protected
security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital.
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation
Protection: Because the interest and/or principal payments on an inflation-protected
security are adjusted periodically for changes in inflation, the income distributed by a fund investing
in such securities may be irregular. Some issuers may not guarantee to pay at maturity at least the original
face value of any inflation-protected securities. Inflation-protected securities are not protected against
deflation. As a result, in a period of deflation, the principal and income of inflation-protected securities
held by a fund will decline and the fund may suffer a loss during such periods. While inflation-protected
securities are expected to be protected from long-term inflationary trends, short-term increases in inflation
may lead to a decline in the value of a fund holding such securities. For example, if interest rates
rise due to reasons other than inflation, a fund’s investment in these securities may not be protected
to the extent that the increase is not reflected in the securities’ inflation measures. In addition,
positive adjustments to principal generally will result in taxable income to a fund at the time of such
adjustments (which generally would be distributed by the fund as part of its taxable dividends), even
though the principal amount is not paid until maturity. The current market value of inflation-protected
securities is not guaranteed and will fluctuate.
|
| Income Risk |
Income
Risk: Income risk is the risk that falling interest rates will cause
a fund’s income to decline because, among other reasons, the proceeds from maturing short-term
securities in its portfolio may be reinvested in lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Tax Liability Risk |
Tax
Liability Risk: Tax liability risk is the
risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal
bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws
by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations
or actions could cause interest from a security to become taxable, possibly retroactively, subjecting
shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause
the value of a security, and therefore, the value of a fund’s shares, to decline.
|
| Municipal Securities Risk |
Municipal Securities Risk: The risk of a municipal
security generally depends on the financial and credit status of the issuer. Municipal securities can
be significantly affected by political, regulatory or economic changes, including changes made in the
law after issuance of the securities, as well as uncertainties in the municipal market related to taxation,
legislative changes or the rights of municipal security holders, including in connection with an issuer’s
insolvency. The municipal securities market can be susceptible to increases in volatility and decreases
in liquidity. The secondary market for certain municipal securities tends to be less well developed or
liquid than many other securities markets, which may adversely affect a fund's ability to sell such municipal
securities at attractive prices. Liquidity can decline unpredictably in response to overall economic
conditions or credit tightening. In addition, there may be less publicly available information about
the financial condition of municipal security issuers than for issuers of other types of securities,
making the securities more difficult to value. The price a fund could receive upon the sale of a portfolio
investment may differ from the fund’s valuation of the investment, particularly for investments
that trade in thin or volatile markets or that are valued using a fair valuation methodology.
|
| Municipal Project-Specific Risk |
Municipal Project-Specific Risk: A fund
may be more sensitive to adverse economic, business or political developments if it invests a substantial
portion of its assets in municipal securities that finance similar types of projects in a segment of
the municipal bond market (such as education, health care, housing, education, utilities or transportation)
or industrial development bonds. A change that affects one project in a particular segment of the market,
such as proposed legislation on the financing of the project, a shortage of the materials needed for
the project, or a declining need for the project, would likely affect all similar projects, thereby increasing
market risk.
|
| State-Specific Risk |
State-Specific Risk:
A fund that focuses its investments primarily in California municipal securities
will be highly sensitive to events affecting the fiscal stability of the State of California and its
agencies, municipalities, authorities and other instrumentalities that issue securities. Having a significant
percentage of its assets invested in the securities of fewer issuers, particularly obligations of government
issuers of a single state, could result in greater credit risk exposure to a smaller number of issuers
due to economic, regulatory or political problems in California. These issues may include economic or
political policy changes, tax base erosion, unfunded pension and healthcare liabilities, state constitutional
limits on tax increases, natural disasters or environmental issues (including drought and wildfires),
budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal
issuers of California. Also, to the extent that a fund makes significant investments in securities issued
to finance projects in a particular segment of the California municipal securities market such focused
investment may cause the value of the fund’s shares to change more than the value of shares of
funds that invest more broadly. These risks are disclosed in more detail in the Portfolio’s Statement
of Additional Information.
|
| Variable Rate Demand Obligations Risk |
Variable Rate Demand Obligations Risk: Certain
variable rate demand obligations (“VRDOs”) may not have an active
secondary market. These VRDOs could be difficult to dispose of if the remarketing agent defaults on its
payment obligation and/or if the fund is not entitled to exercise its demand rights, which could cause
a loss with respect to such VRDOs.
|
| Derivatives Risk |
Derivatives
Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon,
whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging
(attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes.
Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will
work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses
if the market moves in a manner different from that anticipated by a fund or if the cost of the derivative
outweighs the benefit of the hedge. The use of derivatives for non-hedging purposes may be considered
to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly
exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including
counterparty, liquidity, interest rate, market, credit and management risks, as well as
difficulties with respect to valuation. Changes in the value of a derivative may
not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the
principal amount invested. Additional risks are associated with the use of swaps including counterparty
and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations,
whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary
market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty
risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it
may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations.
Swaps may be illiquid or difficult to value. Additionally, payments made or received by a fund under
such derivatives may increase the amount of distributions taxable to you as ordinary income, increase
or decrease the amount of capital gain distributions to you and/or decrease the amount available for
distribution to you as exempt-interest dividends.
|
| High Portfolio Turnover Risk |
High
Portfolio Turnover Risk: When high portfolio turnover (more than 100%) is caused by
the sale of a fund’s portfolio securities and the reinvestment by the fund in other portfolio securities,
such high portfolio turnover may result in increased transaction costs, including brokerage commissions,
dealer mark-ups and other transaction costs. Additionally, the sale of a fund’s portfolio securities
may result in the distribution of higher capital gains as compared to a fund with less active trading
policies. Alternatively, for fixed income funds, a higher portfolio turnover may be in part the result
of bonds being held to their maturity, which may have a minimal impact on transaction costs and taxes.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Operational Risk |
Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Tax Liability Risk |
Tax
Liability Risk: Tax liability risk is the
risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal
bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws
by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations
or actions could cause interest from a security to become taxable, possibly retroactively, subjecting
shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause
the value of a security, and therefore, the value of a fund’s shares, to decline.
|
| Municipal Securities Risk |
Municipal Securities Risk: The risk of a municipal
security generally depends on the financial and credit status of the issuer. Municipal securities can
be significantly affected by political, regulatory or economic changes, including changes made in the
law after issuance of the securities, as well as uncertainties in the municipal market related to taxation,
legislative changes or the rights of municipal security holders, including in connection with an issuer’s

portion of its assets in municipal securities that finance similar types of projects in a segment of
the municipal bond market (such as education, health care, housing, education, utilities or transportation)
or industrial development bonds. A change that affects one project in a particular segment of the market,
such as proposed legislation on the financing of the project, a shortage of the materials needed for
the project, or a declining need for the project, would likely affect all similar projects, thereby increasing
market risk.

| Variable Rate Demand Obligations Risk |
Variable Rate Demand Obligations Risk: Certain
variable rate demand obligations (“VRDOs”) may not have an active
secondary market. These VRDOs could be difficult to dispose of if the remarketing agent defaults on its
payment obligation and/or if the fund is not entitled to exercise its demand rights, which could cause

While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if
the market moves in a manner different from that anticipated by a fund or if the cost of the derivative
outweighs the benefit of the hedge. The use of derivatives for non-hedging purposes may be considered
to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly
exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including
counterparty, liquidity, interest rate, market, credit and management risks, as well as difficulties
with respect to valuation. Changes in the value of a derivative may not correlate perfectly with the
underlying asset, rate or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value. Additionally, payments made or received by a fund under such derivatives may increase
the amount of distributions taxable to you as ordinary income, increase or decrease the amount of capital
gain distributions to you and/or decrease the amount available for distribution to you as exempt-interest
dividends.
|
| High Portfolio Turnover Risk |
High Portfolio Turnover Risk: When
high portfolio turnover (more than 100%) is caused by the sale of a fund’s portfolio securities
and the reinvestment by the fund in other portfolio securities, such high portfolio turnover may result
in increased transaction costs, including brokerage commissions, dealer mark-ups and other transaction
costs. Additionally, the sale of a fund’s portfolio securities may result in the distribution of
higher capital gains as compared to a fund with less active trading policies. Alternatively, for fixed
income funds, a higher portfolio turnover may be in part the result of bonds being held to their maturity,
which may have a minimal impact on transaction costs and taxes.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Operational Risk |
Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

Risk Table - Prospectus Summary - DFA Intermediate-Term Municipal Bond Portfolio
|
Risk [Text Block] |
| Principal Risks |
Principal Risks Because
the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.
An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following is a description of principal
risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because
the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency.
|
| Market Risk |
Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of securities,
and a fund that owns them, to rise or fall.
|
| Interest Rate Risk |
Interest
Rate Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security, including a governmental
entity, may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer’s
credit rating or a perceived change in an issuer’s financial strength may affect a security’s
value, and thus, impact the performance of a fund holding such securities. The ability of a municipal
securities issuer to make payments could be affected by litigation, legislation or other political events
or the bankruptcy of the issuer.
|
| Income Risk |
Income Risk:
Income risk is the risk that falling interest rates will cause a fund’s
income to decline because, among other reasons, the proceeds from maturing short-term securities in its
portfolio may be reinvested in lower-yielding securities.
|
| Call Risk |
Call
Risk: Call risk is the risk that during periods of falling interest
rates, an issuer will call or repay a higher-yielding fixed income security before its maturity date,
forcing a fund to reinvest in fixed income securities with lower interest rates than the original obligations.
|
| Tax Liability Risk |
Tax Liability Risk: Tax liability risk is the
risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal
bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws
by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations
or actions could cause interest from a security to become taxable, possibly retroactively, subjecting
shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause
the value of a security, and therefore, the value of a fund’s shares, to decline.
|
| Municipal Securities Risk |
Municipal Securities Risk: The risk of a municipal
security generally depends on the financial and credit status of the issuer. Municipal securities can
be significantly affected by political, regulatory or economic changes, including changes made in the
law after issuance of the securities, as well as uncertainties in the municipal market related to taxation,
legislative changes or the rights of municipal security holders, including in connection with an issuer’s
insolvency. The municipal securities market can be susceptible to increases in volatility and decreases
in liquidity. The secondary market for certain municipal securities tends to be less well developed or
liquid than many other securities markets, which may adversely affect a fund's ability to sell such municipal
securities at attractive prices. Liquidity can decline unpredictably in response to overall economic
conditions or credit tightening. In addition, there may be less publicly available information about
the financial condition of municipal security issuers than for issuers of other types of securities,
making the securities more difficult to value. The price a fund could receive upon
the sale of a portfolio investment may differ from the fund’s valuation
of the investment, particularly for investments that trade in thin or volatile markets or that are valued
using a fair valuation methodology.
|
| Municipal Project-Specific Risk |
Municipal
Project-Specific Risk: A fund may be more sensitive
to adverse economic, business or political developments if it invests a substantial portion of its assets
in municipal securities that finance similar types of projects in a segment of the municipal bond market
(such as education, health care, housing, education, utilities or transportation) or industrial development
bonds. A change that affects one project in a particular segment of the market, such as proposed legislation
on the financing of the project, a shortage of the materials needed for the project, or a declining need
for the project, would likely affect all similar projects, thereby increasing market risk.
|
| Variable Rate Demand Obligations Risk |
Variable
Rate Demand Obligations Risk: Certain variable
rate demand obligations (“VRDOs”) may not have an active secondary market. These VRDOs could
be difficult to dispose of if the remarketing agent defaults on its payment obligation and/or if the
fund is not entitled to exercise its demand rights, which could cause a loss with respect to such VRDOs.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, whose value is derived from that of other assets,
rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment
position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there
is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can
also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, liquidity, interest rate, market,
credit and management risks, as well as difficulties with respect to valuation. Changes in the value
of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could
lose more than the principal amount invested. Additional risks are associated with the use of swaps including
counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its
contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible
lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of
swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is
the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order
to meet payment obligations. Swaps may be illiquid or difficult to value. Additionally, payments made
or received by a fund under such derivatives may increase the amount of distributions taxable to you

Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions, credit tightening and/or other market developments. Liquidity risk
includes the risk that a fund will experience significant net redemptions at a time when it cannot find
willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss
or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations

An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency.
|
| Market Risk |
Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of securities,
and a fund that owns them, to rise or fall.
|
| Interest Rate Risk |
Interest
Rate Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security, including a governmental
entity, may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer’s
credit rating or a perceived change in an issuer’s financial strength may affect a security’s
value, and thus, impact the performance of a fund holding such securities. The ability of a municipal
securities issuer to make payments could be affected by litigation, legislation or other political events
or the bankruptcy of the issuer. Credit risk is greater for fixed income securities with ratings below
investment grade (e.g., BB+ or below by S&P or Fitch or Ba1 or below by Moody’s). Fixed income
securities that are below investment grade involve high credit risk and are considered speculative. Below
investment grade fixed income securities may also fluctuate in value more than higher quality fixed income
securities and, during periods of market volatility, may be more difficult to sell at the time and price
the Portfolio desires.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Tax Liability Risk |
Tax
Liability Risk: Tax liability risk is the
risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal
bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws
by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations
or actions could cause interest from a security to become taxable, possibly retroactively, subjecting
shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause
the value of a security, and therefore, the value of a fund’s shares, to decline.
|
| Municipal Securities Risk |
Municipal Securities Risk: The risk of a municipal
security generally depends on the financial and credit status of the issuer. Municipal securities can
be significantly affected by political, regulatory or economic changes, including changes made in the
law after issuance of the securities, as well as uncertainties in the municipal market related to taxation,
legislative changes or the rights of municipal security holders, including in connection with an issuer’s
insolvency. The municipal securities market can be susceptible to increases in volatility and decreases
in liquidity. The secondary market for certain municipal securities tends to be less well developed or
liquid than many other securities markets, which may adversely affect a fund's ability to sell such municipal
securities at attractive prices. Liquidity can decline unpredictably in response to overall economic
conditions or credit tightening. In addition, there may be less publicly available information about
the financial condition of municipal security issuers than for issuers of other types of securities,
making the securities more difficult to value. The price a fund could receive upon the sale of a portfolio
investment may differ from the fund’s valuation of the investment, particularly for investments
that trade in thin or volatile markets or that are valued using a fair valuation methodology.
|
| Municipal Project-Specific Risk |
Municipal Project-Specific Risk:
A fund may be more sensitive to adverse economic, business or political developments
if it invests a substantial portion of its assets in municipal securities that finance similar types
of projects in a segment of the municipal bond market (such as education, health care, housing, education,
utilities or transportation) or industrial development bonds. A change that affects one project in a
particular segment of the market, such as proposed legislation on the financing of the project, a shortage
of the materials needed for the project, or a declining need for the project, would likely affect all
similar projects, thereby increasing market risk.
|
| State-Specific Risk |
State-Specific
Risk: A fund that focuses its investments primarily in California
municipal securities will be highly sensitive to events affecting the fiscal stability of the State of
California and its agencies, municipalities, authorities and other instrumentalities that issue securities.
Having a significant percentage of its assets invested in the securities of fewer issuers, particularly
obligations of government issuers of a single state, could result in greater credit risk exposure to
a smaller number of issuers due to economic, regulatory or political problems in California. These issues
may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities,
state constitutional limits on tax increases, natural disasters or environmental issues (including drought
and wildfires), budget deficits and other financial difficulties, and changes in the credit ratings assigned
to municipal issuers of California. Also, to the extent that a fund makes significant investments in
securities issued to finance projects in a particular segment of the California municipal securities
market such focused investment may cause the value of the fund’s shares to change more than the
value of shares of funds that invest more broadly. These risks are disclosed in more detail in the Portfolio’s
Statement of Additional Information.
|
| Variable Rate Demand Obligations Risk |
Variable Rate Demand Obligations
Risk: Certain variable
rate demand obligations (“VRDOs”) may not have an active secondary market. These VRDOs could
be difficult to dispose of if the remarketing agent defaults on its payment obligation and/or if the
fund is not entitled to exercise its demand rights, which could cause a loss with respect to such VRDOs.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, whose value is derived from that of other assets,
rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment
position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there
is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can
also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, liquidity, interest rate, market,
credit and management risks, as well as difficulties with respect to valuation. Changes in the value
of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could
lose more than the principal amount invested. Additional risks are associated with the use of swaps including
counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its
contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible
lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of
swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is
the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order
to meet payment obligations. Swaps may be illiquid or difficult to value. Additionally, payments made
or received by a fund under such derivatives may increase the amount of distributions taxable to you
as ordinary income, increase or decrease the amount of capital gain distributions to you and/or decrease
the amount available for distribution to you as exempt-interest dividends.
|
| High Portfolio Turnover Risk |
High Portfolio Turnover Risk: When high portfolio turnover
(more than 100%) is caused by the sale of a fund’s portfolio securities and the reinvestment by
the fund in other portfolio securities, such high portfolio turnover may result in increased transaction
costs, including brokerage commissions, dealer mark-ups and other transaction costs. Additionally, the
sale of a fund’s portfolio securities may result in the distribution of higher capital gains as
compared to a fund with less active trading policies. Alternatively, for fixed income funds, a higher
portfolio turnover may be in part the result of bonds being held to their maturity, which may have a
minimal impact on transaction costs and taxes.
|
| Liquidity Risk |
Liquidity
Risk: Liquidity risk exists when particular portfolio investments
are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund’s
performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant
net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only
sell its portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced
in periods of market turmoil or in situations where ownership of shares of a fund are concentrated in
one or a few investors. Investments that are illiquid or that trade in lower volumes may be more difficult
to value.
|
| Operational Risk |
Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

invests its assets in a smaller number of issuers. The gains or losses on a single security, therefore,
may have a greater impact on a fund’s net asset value.
|
| Credit Risk |
Credit
Risk: Credit risk is the risk that the issuer of a security, including a governmental
entity, may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer’s
credit rating or a perceived change in an issuer’s financial strength may affect a security’s
value, and thus, impact the performance of a fund holding such securities.
The ability of a municipal securities issuer to make payments could be affected by litigation, legislation
or other political events or the bankruptcy of the issuer. Credit risk is greater
for fixed income securities with ratings below investment grade (e.g., BB or below by S&P or Fitch
or Ba or below by Moody’s). Fixed income securities that are below investment grade involve high
credit risk and are considered speculative. Below investment grade fixed income securities may also fluctuate
in value more than higher quality fixed income securities and, during periods of market volatility, may
be more difficult to sell at the desired time and price.
|
| Income Risk |
Income
Risk: Income risk is the risk that falling interest rates will cause
a fund’s income to decline because, among other reasons, the proceeds from maturing short-term
securities in its portfolio may be reinvested in lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Tax Liability Risk |
Tax
Liability Risk: Tax liability risk is the
risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal
bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws
by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations
or actions could cause interest from a security to become taxable, possibly retroactively, subjecting
shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause
the value of a security, and therefore, the value of a fund’s shares, to decline.
|
| Municipal Securities Risk |
Municipal Securities Risk: The risk of a municipal
security generally depends on the financial and credit status of the issuer. Municipal securities can
be significantly affected by political, regulatory or economic changes, including changes made in the
law after issuance of the securities, as well as uncertainties in the municipal market related to taxation,
legislative changes or the rights of municipal security holders, including in connection with an issuer’s
insolvency. The municipal securities market can be susceptible to increases in volatility and decreases
in liquidity. The secondary market for certain municipal securities tends to be less well developed or
liquid than many other securities markets, which may adversely affect a fund's ability to sell such municipal
securities at attractive prices. Liquidity can decline unpredictably in response to overall economic
conditions or credit tightening. In addition, there may be less publicly available information about
the financial condition of municipal security issuers than for issuers of other types of securities,
making the securities more difficult to value. The price a fund could receive upon
the sale of a portfolio investment may differ from the fund’s valuation
of the investment, particularly for investments that trade in thin or volatile markets or that are valued
using a fair valuation methodology.
|
| Municipal Project-Specific Risk |
Municipal
Project-Specific Risk: A fund may be more sensitive
to adverse economic, business or political developments if it invests a substantial portion of its assets
in municipal securities that finance similar types of projects in a segment of the municipal bond market
(such as education, health care, housing, education, utilities or transportation) or industrial development
bonds. A change that affects one project in a particular segment of the market, such as proposed legislation
on the financing of the project, a shortage of the materials needed for the project, or a declining need
for the project, would likely affect all similar projects, thereby increasing market risk.
|
| State-Specific Risk |
State-Specific Risk: A fund that focuses its
investments primarily in New York municipal securities will be highly sensitive to events affecting the
fiscal stability of the State of New York and its agencies, municipalities, authorities and other instrumentalities
that issue securities. Having a significant percentage of its assets invested in the securities of fewer
issuers, particularly obligations of government issuers of a single state, could result in greater credit
risk exposure to a smaller number of issuers due to economic, regulatory or political problems in New
York. Also, to the extent that a fund makes significant investments in securities issued to finance projects
in a particular segment of the New York municipal securities market such focused investment may cause
the value of the fund’s shares to change more than the value of shares of funds that invest more
broadly. These risks are disclosed in more detail in the Portfolio’s Statement of Additional Information.
|
| Variable Rate Demand Obligations Risk |
Variable
Rate Demand Obligations Risk: Certain variable
rate demand obligations (“VRDOs”) may not have an active secondary market. These VRDOs could
be difficult to dispose of if the remarketing agent defaults on its payment obligation and/or if the
fund is not entitled to exercise its demand rights, which could cause a loss with respect to such VRDOs.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, whose value is derived from that of other assets,
rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment
position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there
is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can
also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, liquidity, interest rate, market,
credit and management risks, as well as difficulties with respect to valuation. Changes in the value
of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could
lose more than the principal amount invested. Additional risks are associated with the use of swaps including
counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its
contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible
lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of
swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is
the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order
to meet payment obligations. Swaps may be illiquid or difficult to value. Additionally, payments made
or received by a fund under such derivatives may increase the amount of distributions taxable to you
as ordinary income, increase or decrease the amount of capital gain distributions to you and/or decrease
the amount available for distribution to you as exempt-interest dividends.
|
| High Portfolio Turnover Risk |
High Portfolio Turnover Risk: When high portfolio turnover
(more than 100%) is caused by the sale of a fund’s portfolio securities and the reinvestment by
the fund in other portfolio securities, such high portfolio turnover may result in increased transaction
costs, including brokerage commissions, dealer mark-ups and other transaction costs. Additionally, the
sale of a fund’s portfolio securities may result in the distribution of higher capital gains as
compared to a fund with less active trading policies. Alternatively, for fixed income funds, a higher
portfolio turnover may be in part the result of bonds being held to their maturity, which may have a
minimal impact on transaction costs and taxes.
|
| Liquidity Risk |
Liquidity
Risk: Liquidity risk exists when particular portfolio investments
are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund’s
performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant
net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only
sell its portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced
in periods of market turmoil or in situations where ownership of shares of a fund are concentrated in
one or a few investors. Investments that are illiquid or that trade in lower volumes may be more difficult
to value.
|
| Operational Risk |
Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control,
including instances at third parties. A fund and its advisor seek to reduce these operational risks through
controls and procedures. However, measures that seek to reduce these operational risks through controls
and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your

|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Interest Rate Risk |
Interest Rate Risk:
Fixed income securities are subject to interest rate risk because the prices of
fixed income securities tend to move in the opposite direction of interest rates. When interest rates
rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund
may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security
prices rise. In general, fixed income securities with longer maturities are more sensitive to changes
in interest rates.
|
| Non-Diversification Risk |
Non-Diversification Risk:
The risk that a fund may be more volatile than a diversified fund because a fund

Risk Table - Prospectus Summary - World ex U.S. Targeted Value Portfolio
|
Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing

|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities
and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign issuers may not be subject to uniform accounting, auditing and financial
reporting standards and there may be less reliable and publicly available financial and other information
about such issuers, as compared to U.S. issuers. A fund may have greater difficulty voting proxies, exercising
shareholder rights, securing dividends and/or interest and obtaining information regarding corporate
actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments
in foreign courts than with respect to domestic issuers in U.S. courts. Depositary
receipts are generally subject to the same risks as the foreign securities that they evidence or into
which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly
unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications
to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited
securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may
be less readily available public information about the issuer.
|
| Small and Mid-Cap Company Risk |
Small
and Mid-Cap Company Risk: Securities of small and mid-cap
companies are often less liquid than those of large companies and this could make it difficult to sell
a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company
stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are
also more vulnerable than larger companies to adverse business or economic developments and they may
have more limited resources.
|
| Value Investment Risk |
Value Investment
Risk: Value stocks may perform differently from the market as a
whole and an investment strategy purchasing these securities may cause a fund to at times underperform
equity funds that use other investment strategies. Value stocks can react differently to political, economic,
and industry developments than the market as a whole and other types of stocks. Value stocks also may
underperform the market for long periods of time.
|
| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| China Investments Risk |
China Investments Risk:
There are special risks associated with investments in China, Hong Kong, and Taiwan.
China, Hong Kong, and Taiwan are highly interconnected and interdependent, with relationships built on
trade, finance, culture, and politics. Despite prior economic and trade reforms and the prior expansion
of private ownership of companies in certain sectors, the Chinese government still exercises substantial
influence over many aspects of the private sector and may own or control many companies, including by
embedding Chinese Communist Party or People’s Armed Forces Department personnel in Chinese companies.
In addition, the Chinese government continues to maintain a major role in economic policy making and
may alter or discontinue economic or trade reforms at any time. Investing in China involves risks of
losses due to expropriation, nationalization, confiscation of assets and property, and the imposition
of restrictions on foreign investments and on repatriation of capital invested. Investments
in China, Hong Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating
relations with the U.S. as economic and strategic competition between the U.S. and China intensifies,
which could result in further tariffs, trade restrictions, sanctions, or other actions that adversely
impact the value of such investments. A reduction in spending on Chinese products and services, supply
chain diversification or the institution of additional tariffs or other trade barriers, including as
a result of heightened trade tensions between China and the United States may also have an adverse impact
on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political
and economic relationship with China. Certain securities issued by companies located or operating in
China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to a fund investing
in such securities. In addition, investments in special structures that utilize contractual arrangements
to provide exposure to certain Chinese companies, known as variable interest entities (“VIEs”), that
operate in sectors in which China restricts and/or prohibits foreign investments may present additional
risks. The Chinese government’s acceptance of the VIE structure is evolving. It is uncertain whether
Chinese officials and regulators will withdraw their acceptance of the structure generally, or with respect
to certain industries, or whether Chinese courts or arbitration bodies would decline to enforce the contractual
rights of foreign investors, each of which would likely have significant, detrimental, and possibly permanent
losses on the value of such investments.
|
| Tax Advantage Strategy Risk |
Tax Advantage
Strategy Risk: An investment strategy that
considers the tax implications of investment decisions may alter the management of a fund and affect
portfolio holdings, when compared to other mutual funds that do not take into account potential tax implications.
The Advisor anticipates that performance of such a fund may deviate from that of mutual funds that do
not take into account potential tax implications.
|
| Derivatives Risk |
Derivatives
Risk: Derivatives are instruments, such as futures contracts, and options thereon,
and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices.
The use of derivatives for non-hedging purposes may be considered to carry more risk than other types
of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those
derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s or
its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce
these operational risks through controls and procedures. However, measures that seek to reduce these
operational risks through controls and procedures may not address every possible risk and may be inadequate
to address these risks.
|
| Cyber Security Risk |
Cyber Security
Risk: A fund and its service providers’ use of internet, technology
and information systems may expose the fund to potential risks linked to cyber security breaches of those
technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized
party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or
its service providers to suffer data corruption or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies to
adverse business or economic developments and they may have more limited resources.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to
valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset,
rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and procedures. However, measures that seek to reduce
these operational risks through controls and procedures may not address every possible risk and may be
inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be
forced to convert, its currency to another currency, changing its value against the U.S. dollar). The
Portfolio does not hedge foreign currency risk. Foreign issuers may not be subject
to uniform accounting, auditing and financial reporting standards and there may be less reliable and
publicly available financial and other information about such issuers, as compared to U.S. issuers. A
fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends and/or
interest and obtaining information regarding corporate actions on a timely basis, pursuing legal remedies,
and obtaining judgments with respect to foreign investments in foreign courts than with respect to domestic
issuers in U.S. courts. Depositary receipts are generally subject to the same risks
as the foreign securities that they evidence or into which they may be converted. In addition, the underlying
issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts,
are under no obligation to distribute shareholder communications to the holders of such receipts, or
to pass through to them any voting rights with respect to the deposited securities. Depositary receipts
that are not sponsored by the issuer may be less liquid and there may be less readily available public
information about the issuer.
|
| Geographic Focus Risk |
Geographic Focus Risk:
If a fund focuses its investments in securities of issuers located in a particular
country or region, the fund may be subjected, to a greater extent than if its investments were less focused,
to the risks of volatile economic cycles and/or conditions and developments that may be particular to
that country or region, such as: adverse securities markets; adverse exchange rates; adverse social,
political, regulatory, economic, business, environmental or other developments; or natural disasters.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested.

manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the

Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Foreign Government Debt Risk |
Foreign Government Debt Risk:
The risk that: (a) the governmental entity that controls the repayment of government
debt may not be willing or able to repay the principal and/or to pay the interest when it becomes due,
due to factors such as political considerations, the relative size of the governmental entity’s
debt position in relation to the economy, cash flow problems, insufficient foreign currency reserves,
the failure to put in place economic reforms required by the International Monetary Fund or other multilateral
agencies, and/or other national economic factors; (b) governments may default on their debt securities,
which may require holders of such securities to participate in debt rescheduling; and (c) there is no
legal or bankruptcy process by which defaulted government debt may be collected in whole or in part.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Interest Rate Risk |
Interest Rate
Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security may be unable to make interest
payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived
change in an issuer’s financial strength may affect a security’s value, and thus, impact
the performance of a fund holding such securities. Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that
are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities
sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from
the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment
position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there
is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can
also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, settlement, liquidity, interest
rate, market, credit and management risks, as well as difficulties with respect to valuation. Changes
in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and
a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Liquidity Risk |
Liquidity Risk:
Liquidity risk exists when particular portfolio investments are difficult to purchase
or sell. To the extent that a fund holds illiquid investments, the fund’s performance may be reduced
due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that
a fund will experience significant net redemptions at a time when it cannot find willing buyers for its
portfolio securities or can only sell its portfolio securities at a material loss or at increased costs.
Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of
shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade
in lower volumes may be more difficult to value.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency

|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also

Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A
fund and its service providers’ use of internet, technology and information systems may expose
the fund to potential risks linked to cyber security breaches of those technological or information systems.
Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary
information, customer data, or fund assets, or cause the fund and/or its service providers to suffer
data corruption or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such
securities. Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest.
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection:
Because the interest and/or principal payments on an inflation-protected security
are adjusted periodically for changes in inflation, the income distributed by a fund investing in such
securities may be irregular. Although the U.S. Treasury guarantees to pay at maturity at least the original
face value of any inflation-protected securities the Treasury issues, other issuers may not offer the
same guarantee. Inflation-protected securities are not protected against deflation. As a result, in a
period of deflation, the principal and income of inflation-protected securities held by a fund will decline
and the fund may suffer a loss during such periods. While inflation-protected securities are expected
to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline
in the value of a fund holding such securities. For example, if interest rates rise due to reasons other
than inflation, a fund’s investment in these securities may not be protected to the extent that
the increase is not reflected in the securities’ inflation measures. In addition, positive adjustments
to principal generally will result in taxable income to a fund at the time of such adjustments (which
generally would be distributed by the fund as part of its taxable dividends), even though the principal
amount is not paid until maturity. The current market value of inflation-protected securities is not
guaranteed and will fluctuate.
|
| Income Risk |
Income Risk:
Income risk is the risk that falling interest rates will cause a fund’s
income to decline because, among other reasons, the proceeds from maturing short-term securities in its
portfolio may be reinvested in lower-yielding securities.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment
position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there
is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can
also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated
by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives
for non-hedging purposes may be considered to carry more risk than other types of investments. When a
fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative
instruments are subject to a number of risks including counterparty, settlement, liquidity, interest
rate, market, credit and management risks, as well as difficulties with respect to valuation. Changes
in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and
a fund could lose more than the principal amount invested.
|
| Liquidity Risk |
Liquidity
Risk: Liquidity risk exists when particular portfolio investments
are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund’s
performance may be reduced due to an inability to sell the investments at opportune prices or times.
Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading
volume, adverse investor perceptions, credit tightening and/or other market developments. Liquidity risk
includes the risk that a fund will experience significant net redemptions at a time when it cannot find
willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss
or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations
where ownership of shares of a fund are concentrated in one or a few investors. Investments that are
illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s
or its advisor’s control, including instances at third parties. A fund and its advisor seek to
reduce these operational risks through controls and
procedures. However, measures that seek to reduce these operational risks through
controls and procedures may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential
risks linked to cyber security breaches of those technological or information systems. Cyber security
breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information,
customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption
or lose operational functionality.

|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding
the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate
assets to an underlying fund or asset class that underperforms other funds or asset classes. There can
be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved.
Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying
funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to
a proportionate share of the expenses of those underlying funds in addition to the expenses of a fund
of funds. Certain risks of the Underlying Funds’ investments that are principal risks of investing
in the Portfolio are described below.
|
| Equity Market Risk |
Equity
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|

Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts. Depositary receipts are generally subject to the same risks as the foreign securities
that they evidence or into which they may be converted. In addition, the underlying issuers of certain
depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation
to distribute shareholder communications to the holders of such receipts, or to pass through to them
any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored
by the issuer may be less liquid and there may be less readily available public information about the
issuer.
|
| Foreign Government Debt Risk |
Foreign Government Debt Risk: The
risk that: (a) the governmental entity that controls the repayment of government debt may not be willing
or able to repay the principal and/or to pay the interest when it becomes due, due to factors such as
political considerations, the relative size of the governmental entity’s debt position in relation
to the economy, cash flow problems, insufficient foreign currency reserves, the failure to put in place
economic reforms required by the International Monetary Fund or other multilateral agencies, and/or other
national economic factors; (b) governments may default on their debt securities, which may require holders
of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy process
by which defaulted government debt may be collected in whole or in part.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.

system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.

Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Social Investment
Risk: A fund with social issue screens may limit the number of investment

lending involves the risk that the borrower may fail to return the securities in a timely manner or at
all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities.
A fund could also lose money if it does not recover the securities and/or the value of the collateral
falls, including the value of investments made with cash collateral. Securities lending also may have
certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its
advisor seek to reduce these operational risks through controls and procedures. However, measures that
seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.

|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.
|
| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to
the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid
and there may be less readily available public information about the issuer.
|
| Geographic Focus Risk |
Geographic Focus Risk: If a
fund focuses its investments in securities of issuers located in a particular country or region, the
fund may be subjected, to a greater extent than if its investments were less focused, to the risks of
volatile economic cycles and/or conditions and developments that may be particular to that country or
region, such as: adverse securities markets; adverse exchange rates; adverse social, political, regulatory,
economic, business, environmental or other developments; or natural disasters.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Social Investment Risk |
Social Investment
Risk: A fund with social issue screens may limit the number of investment
opportunities available to the fund, and as a result, at times the Portfolio may underperform funds that
are not subject to such special investment conditions. For example, a fund with social issue screens
may decline to purchase certain securities when it is otherwise advantageous to do so, or may sell certain
securities for social reasons when it is otherwise disadvantageous to do so. There is no guarantee that
a fund’s investments will reflect the social considerations of any particular investor.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.

|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| China Investments Risk |
China Investments Risk:
There are special risks associated with investments in China, Hong Kong, and Taiwan.
China, Hong Kong, and Taiwan are highly interconnected and interdependent, with relationships built on
trade, finance, culture, and politics. Despite prior economic and trade reforms and the prior expansion
of private ownership of companies in certain sectors, the Chinese government still exercises substantial
influence over many aspects of the
private sector and may own or control many companies, including by embedding Chinese
Communist Party or People’s Armed Forces Department personnel in Chinese companies. In addition, the
Chinese government continues to maintain a major role in economic policy making and may alter or discontinue
economic or trade reforms at any time. Investing in China involves risks of losses due to expropriation,
nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments
and on repatriation of capital invested. Investments in China, Hong
Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with
the U.S. as economic and strategic competition between the U.S. and China intensifies, which could result
in further tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of
such investments. A reduction in spending on Chinese products and services, supply chain diversification
or the institution of additional tariffs or other trade barriers, including as a result of heightened
trade tensions between China and the United States may also have an adverse impact on the Chinese economy.
In addition, investments in Taiwan could be adversely affected by its political and economic relationship
with China. Certain securities issued by companies located or operating in China, such as China A-shares,
are also subject to trading restrictions, quota limitations and less market liquidity, which could pose
risks to a fund investing in such securities. In addition, investments in special structures that utilize
contractual arrangements to provide exposure to certain Chinese companies, known as variable interest
entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign investments
may present additional risks. The Chinese government’s acceptance of the VIE structure is evolving.
It is uncertain whether Chinese officials and regulators will withdraw their acceptance of the structure
generally, or with respect to certain industries, or whether Chinese courts or arbitration bodies would
decline to enforce the contractual rights of foreign investors, each of which would likely have significant,
detrimental, and possibly permanent losses on the value of such investments.

| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing

|
| Fund of Funds Risk |
Fund of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding
the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate
assets to an underlying fund or asset class that underperforms other funds or asset classes. There can
be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved.
Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying
funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to a proportionate
share of the expenses of those underlying funds in addition to the expenses of a fund of funds. Certain
risks of the Underlying Funds’ investments that are principal risks of investing in the Portfolio are
described below.

Foreign Securities and Currencies
Risk: Foreign securities prices may decline or fluctuate because
of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities
markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility
that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will
convert, or be forced to convert, its currency to another currency, changing its value against the U.S.
dollar). The Portfolio and each Underlying Fund do not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing

|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Social Investment Risk |
Social Investment Risk:
A fund with social issue screens may limit the number of investment opportunities
available to the fund, and as a result, at times the Portfolio may underperform funds that are not subject
to such special investment conditions. For example, a fund with social issue screens may decline to purchase
certain securities when it is otherwise advantageous to do so, or may sell certain securities for social
reasons when it is otherwise disadvantageous to do so. There is no guarantee that a fund’s investments
will reflect the social considerations of any particular investor.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present
little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government,
that are supported only by the issuer’s right to borrow from the U.S. Treasury, subject to certain
limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government
that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject
to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit
of the agency may still involve a risk of non-payment of principal and/or interest.
|
| Income Risk |
Income Risk: Income risk is the risk
that falling interest rates will cause a fund’s income to decline because, among other reasons, the
proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Foreign Securities and Currencies Risk |
Foreign
Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio hedges foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Derivatives Risk |
Derivatives Risk:
Derivatives are instruments, such as futures contracts, and options thereon, and foreign currency forward
contracts, whose value is derived from that of other assets, rates or indices. Derivatives can be used
for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging
purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy
will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause
losses if the market moves in a manner different from that anticipated by a fund or if the cost of the
derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally not possible
to precisely match the foreign currency exposure of such foreign currency forward contracts to the value
of the securities involved due to fluctuations in the market values of such securities and cash flows
into and out of a fund between the date a foreign currency forward contract is entered into and the date
it expires. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties with
respect to valuation. Changes in the value of a derivative may not correlate perfectly with the underlying
asset, rate or index, and a fund could lose more than the principal amount invested. Additional risks
are associated with the use of swaps including counterparty and credit risk (the risk that the other
party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity
risk exists when particular portfolio investments are difficult to purchase or sell. To the extent that
a fund holds illiquid investments, the fund’s performance may be reduced due to an inability to sell
the investments at opportune prices or times. Liquid portfolio investments may become illiquid or less
liquid after purchase by a fund due to low trading volume, adverse investor perceptions, credit tightening
and/or other market developments. Liquidity risk includes the risk that a fund will experience significant
net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only
sell its portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced
in periods of market turmoil or in situations where ownership of shares of a fund are concentrated in
one or a few investors. Investments that are illiquid or that trade in lower volumes may be more difficult
to value.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its
advisor seek to reduce these operational risks through controls and procedures. However, measures that
seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Risk [Text Block] |
| Principal Risks |
Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Sustainability Consideration Investment Risk |
Sustainability Consideration
Investment Risk: A fund that takes into account sustainability considerations
may limit the number of investment opportunities available to the fund, and as a result, at times, may
underperform funds that are not subject to such sustainability considerations. For example, a fund may
decline to purchase, or underweight its investment in, certain securities due to sustainability considerations
when other investment considerations would suggest that a more significant investment in such securities
would be advantageous. A fund may also overweight its investment in certain securities due to sustainability
considerations when other investment considerations would suggest that a lesser investment in such securities
would be advantageous. In addition, a fund may sell or retain certain securities due to sustainability
considerations when it is otherwise disadvantageous to do so. The sustainability considerations may also
cause a fund’s industry allocations to deviate from those of funds without these considerations and
of conventional benchmarks. The Advisor may also not be able to assess the sustainability of each company
with securities eligible for purchase. For example, the Advisor may not be able to determine all of the
sustainability considerations for each company because the third party service providers may not have
data on the entire universe of companies with securities considered by the Advisor, or may not have information
with respect to each factor considered as a sustainability consideration. Furthermore, “sustainability”
is not uniformly defined, and there are significant differences in interpretations of what it means for
a company to meet sustainability criteria. A fund’s exposure to companies, industries and sectors of
the market may be affected by sustainability data obtained that may be inaccurate and the Advisor’s
assessment of a company’s sustainability may differ from assessments made by other funds, managers,
or investors. As a result, there is no guarantee that a fund’s investments will reflect the sustainability
considerations of any particular investor.

| Derivatives Risk |
Derivatives
Risk: Derivatives are instruments, such as futures contracts, and options thereon,
whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging
purposes may be considered to
carry more risk than other types of investments. When a fund uses derivatives,
the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject
to a number of risks including counterparty, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested.

Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.

cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational

company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Foreign Securities and Currencies Risk |
Foreign Securities
and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder
communications to the holders of such receipts, or to pass through to them any voting rights with respect
to the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid
and there may be less readily available public information about the issuer.
|
| Geographic Focus Risk |
Geographic Focus Risk: If a
fund focuses its investments in securities of issuers located in a particular country or region, the
fund may be subjected, to a greater extent than if its investments were less focused, to the risks of
volatile economic cycles and/or conditions and developments that may be particular to that country or
region, such as: adverse securities markets; adverse exchange rates; adverse social, political, regulatory,
economic, business, environmental or other developments; or natural disasters.

| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk:
Foreign securities prices may decline or fluctuate because of: (a) economic or
political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors
holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency
will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced

does not hedge foreign currency risk. Foreign issuers may not be subject

|
| Geographic Focus Risk |
Geographic Focus Risk:
If a fund focuses its investments in securities of issuers located in a particular
country or region, the fund may be subjected, to a greater extent than if its investments were less focused,
to the risks of volatile economic cycles and/or conditions and developments that may be particular to
that country or region, such as: adverse securities markets; adverse exchange rates; adverse social,
political, regulatory, economic, business, environmental or other developments; or natural disasters.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| China Investments Risk |
China Investments Risk: There are special risks
associated with investments in China, Hong Kong, and Taiwan. China, Hong Kong, and Taiwan are highly
interconnected and interdependent, with relationships built on trade, finance, culture, and politics.
Despite prior economic and trade reforms and the prior expansion of private ownership of companies in
certain sectors, the Chinese government still exercises substantial influence over many aspects of the
private sector and may own or control many companies, including by embedding Chinese Communist Party
or People’s Armed Forces Department personnel in Chinese companies. In addition, the Chinese government
continues to maintain a major role in economic policy making and may alter or discontinue economic or
trade reforms at any time. Investing in China involves risks of losses due to expropriation, nationalization,
confiscation of assets and property, and the imposition of restrictions on foreign investments and on
repatriation of capital invested. Investments in China, Hong
Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating relations with
the U.S. as economic and strategic competition between the U.S. and China intensifies, which could result
in further tariffs, trade restrictions, sanctions, or other actions that adversely impact the value of
such investments. A reduction in spending on Chinese products and services, supply chain diversification
or the institution of additional tariffs or other trade barriers, including as a result of heightened
trade tensions between China and the United States may also have an adverse impact on the Chinese economy.
In addition, investments in Taiwan could be adversely affected by its political and economic relationship
with China. Certain securities issued by companies located or operating in China, such as China A-shares,
are also subject to trading restrictions, quota limitations and less market liquidity, which could pose
risks to a fund investing in such securities. In addition, investments in special structures that utilize
contractual arrangements to provide exposure to certain Chinese companies, known as variable interest
entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign investments
may present additional risks. The Chinese government’s acceptance of the VIE structure is evolving.
It is uncertain whether Chinese officials and regulators will withdraw their acceptance of the structure
generally, or with respect to certain industries, or whether Chinese courts or arbitration bodies would
decline to enforce the contractual rights of foreign investors, each of which would likely have significant,
detrimental, and possibly permanent losses on the value of such investments.

a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.

such as futures contracts, and options thereon, whose value is derived from that of other assets, rates
or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than
other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks
of those derivatives. Derivative instruments are subject to a number of risks including counterparty,
settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties with
respect to valuation. Changes in the value of a derivative may not correlate perfectly with the underlying
asset, rate or index, and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s or
its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce
these operational risks through controls and procedures. However, measures that seek to reduce these
operational risks through controls and procedures may not address every possible risk and may be inadequate
to address these risks.
|
| Cyber Security Risk |
Cyber Security
Risk: A fund and its service providers’ use of internet, technology
and information systems may expose the fund to potential risks linked to cyber security breaches of those
technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized
party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or
its service providers to suffer data corruption or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Sustainability Consideration Investment Risk |
Sustainability
Consideration Investment Risk: A fund that takes into account
sustainability considerations may limit the number of investment opportunities available to the fund,
and as a result, at times, may underperform funds that are not subject to such sustainability considerations.
For example, a fund may decline to purchase, or underweight its investment in, certain securities due
to sustainability considerations when other investment considerations would suggest that a more significant
investment in such securities would be advantageous. A fund may also overweight its investment in certain
securities due to sustainability considerations when other investment considerations would suggest that
a lesser investment in such securities would be advantageous. In addition, a fund may sell or retain
certain securities due to sustainability considerations when it is otherwise disadvantageous to do so.
The sustainability considerations may also cause a fund’s industry allocations to deviate from those
of funds without these considerations and of conventional benchmarks. The Advisor may also not be able
to assess the sustainability of each company with securities eligible for purchase. For example, the
Advisor may not be able to determine all of the sustainability considerations for each company because
the third party service providers may not have data on the entire universe of companies with securities
considered by the Advisor, or may not have information with respect to each factor considered as a sustainability
consideration. Furthermore, “sustainability” is not uniformly defined, and there are significant
differences in interpretations of what it means for a company to meet sustainability criteria. A fund’s
exposure to companies, industries and sectors of the market may be affected by sustainability data obtained
that may be inaccurate and the Advisor’s assessment of a company’s sustainability may differ from
assessments made by other funds, managers, or investors. As a result, there is no guarantee that a fund’s
investments will reflect the sustainability considerations of any particular investor.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
Depositary receipts are generally subject to the same risks as the foreign securities
that they evidence or into which they may be converted. In addition, the underlying issuers of certain
depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation
to distribute shareholder communications to the holders of such receipts, or to pass through to them
any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored
by the issuer may be less liquid and there may be less readily available public information about the
issuer.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities
of small and mid-cap companies are often less liquid than those of large companies and this could make
it difficult to sell a small or mid-cap company security at a desired time or price. As a result, small
and mid-cap company stocks may fluctuate relatively more in price. In general, small and mid-capitalization
companies are also more vulnerable than larger companies to adverse business or economic developments
and they may have more limited resources.
|
| Value Investment Risk |
Value
Investment Risk: Value stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies. Value stocks can react differently
to political, economic, and industry developments than the market as a whole and other types of stocks.
Value stocks also may underperform the market for long periods of time.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| China Investments Risk |
China Investments Risk:
There are special risks associated with investments in China, Hong Kong, and Taiwan.
China, Hong Kong, and Taiwan are highly interconnected and interdependent, with relationships built on
trade, finance, culture, and politics. Despite prior economic and trade reforms and the prior expansion
of private ownership of companies in certain sectors, the Chinese government still exercises substantial
influence over many aspects of the private sector and may own or control many companies, including by
embedding Chinese Communist Party or People’s Armed Forces Department personnel in Chinese companies.
In addition, the Chinese government continues to maintain a major role in economic policy making and
may alter or discontinue economic or trade reforms at any time. Investing in China involves risks of
losses due to expropriation, nationalization, confiscation of assets and property, and the imposition
of restrictions on foreign investments and on repatriation of capital invested. Investments
in China, Hong Kong, and Taiwan are also subject to the risk of escalating tensions and deteriorating
relations with the U.S. as economic and strategic competition between the U.S. and China intensifies,
which could result in further tariffs, trade restrictions, sanctions, or other actions that adversely
impact the value of such investments. A reduction in spending on Chinese products and services, supply
chain diversification or the institution of additional tariffs or other trade barriers, including as
a result of heightened trade tensions between China and the United States may also have an adverse impact
on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political
and economic relationship with China. Certain securities issued by companies located or operating in
China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market
liquidity, which could pose risks to a fund investing in such securities. In addition, investments in
special structures that utilize contractual arrangements to provide exposure to certain Chinese companies,
known as variable interest entities (“VIEs”), that operate in sectors in which China restricts and/or
prohibits foreign investments may present additional risks. The Chinese government’s acceptance of
the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw
their acceptance of the structure generally, or with respect to certain industries, or whether Chinese
courts or arbitration bodies would
decline to enforce the contractual rights of foreign investors, each of which
would likely have significant, detrimental, and possibly permanent losses on the value of such investments.

| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes
may be considered to carry more risk than other types of investments. When a fund uses derivatives, the
fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to
a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management
risks, as well as difficulties with respect to valuation. Changes in the value of a derivative may not
correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal
amount invested.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its
advisor seek to reduce these operational risks through controls and procedures. However, measures that
seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.
|
| Large Shareholder Risk |
Large Shareholder Risk:
Certain shareholders, including other funds or accounts advised by the Advisor,
may from time to time own a substantial amount of a fund’s shares. In addition, a third-party investor,
the Advisor, an authorized participant, a lead market maker, or another entity may invest in a fund and
hold its investment for a limited period of time solely to facilitate commencement of a fund or to facilitate
a fund achieving a specified size or scale. There can be no assurance that any large shareholder would
not redeem its investment, that the size of a fund would be maintained at such levels or that a fund
would continue to meet applicable listing requirements. Redemptions by large shareholders could have
a significant negative impact on a fund. In addition, transactions by large shareholders may account
for a large percentage of the trading volume on the listing exchange and may, therefore, have a material
upward or downward effect on the market price of the shares.

that a fund’s investments will reflect the sustainability considerations of any particular investor.
|
| Income Risk |
Income Risk: Income risk is the risk
that falling interest rates will cause a fund’s income to decline because, among other reasons, the
proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Interest Rate Risk |
Interest
Rate Risk: Fixed income securities are subject to interest rate risk
because the prices of fixed income securities tend to move in the opposite direction of interest rates.
When interest rates rise, fixed income security prices fall. During periods of very low or negative interest
rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed
income security prices rise. In general, fixed income securities with longer maturities are more sensitive
to changes in interest rates.
|
| Credit Risk |
Credit Risk:
Credit risk is the risk that the issuer of a security may be unable to make interest
payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived change
in an issuer’s financial strength may affect a security’s value, and thus, impact the performance
of a fund holding such securities. Government agency obligations have different levels of credit support
and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities
of the U.S. Government that are supported by the full faith and credit of the United States, such as
the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued
by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer’s
right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies
and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing
agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government
agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment
of principal and/or interest.
|
| Foreign Securities and Currencies Risk |
Foreign Securities
and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio hedges foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Derivatives Risk |
Derivatives Risk:
Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency
forward contracts, whose value is derived from that of other assets, rates or indices. Derivatives can
be used for hedging (attempting to reduce risk by offsetting one investment position with another) or
non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that
a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate
gains or cause losses if the market moves in a manner different from that anticipated by a fund or if
the cost of the derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally
not possible to precisely match the foreign currency exposure of such foreign currency forward contracts
to the value of the securities involved due to fluctuations in the market values of such securities and
cash flows into and out of a fund between the date a foreign currency forward contract is entered into
and the date it expires. The use of derivatives for non-hedging purposes may be considered to carry more
risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed
to the risks of those derivatives. Derivative instruments are subject to a number of risks including
counterparty, settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties
with respect to valuation. Changes in the value of a derivative may not correlate perfectly with the
underlying asset, rate
or index, and a fund could lose more than the principal amount invested. Additional
risks are associated with the use of swaps including counterparty and credit risk (the risk that the
other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy
or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement).
Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund
is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate
portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid
or difficult to value.
|
| Liquidity Risk |
Liquidity Risk:
Liquidity risk exists when particular portfolio investments are difficult to purchase
or sell. To the extent that a fund holds illiquid investments, the fund’s performance may be reduced
due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that
a fund will experience significant net redemptions at a time when it cannot find willing buyers for its
portfolio securities or can only sell its portfolio securities at a material loss or at increased costs.
Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of
shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade
in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Operational Risk |

human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”). Various
operational events or circumstances are outside a fund’s or its advisor’s control, including instances
at third parties. A fund and its advisor seek to reduce these operational risks through controls and
procedures. However, measures that seek to reduce these operational risks through controls and procedures
may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential risks
linked to cyber security breaches of those technological or information systems. Cyber security breaches,
amongst other things, could allow an unauthorized party to gain access to proprietary information, customer
data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose
operational functionality.

An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding
the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate
assets to an underlying fund or asset class that underperforms other funds or asset classes. There can
be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved.
Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying
funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to a proportionate
share of the expenses of those underlying funds in addition to the expenses of a fund of funds. Certain
risks of the Underlying Funds’ investments that are principal risks of investing in the Portfolio are
described below.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.

shareholder rights, securing dividends and/or interest and obtaining information regarding corporate
actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments
in foreign courts than with respect to domestic issuers in U.S. courts. Depositary
receipts are generally subject to the same risks as the foreign securities that they evidence or into
which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly
unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications
to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited
securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may
be less readily available public information about the issuer.
|
| Foreign Government Debt Risk |
Foreign
Government Debt Risk: The risk that: (a) the
governmental entity that controls the repayment of government debt may not be willing or able to repay
the principal and/or to pay the interest when it becomes due, due to factors such as political considerations,
the relative size of the governmental entity’s debt position in relation to the economy, cash flow
problems, insufficient foreign currency reserves, the failure to put in place economic reforms required
by the International Monetary Fund or other multilateral agencies, and/or other national economic factors;
(b) governments may default on their debt securities, which may require holders of such securities to
participate in debt rescheduling; and (c) there is no legal or bankruptcy process by which defaulted
government debt may be collected in whole or in part.
|
| Profitability Investment Risk |
Profitability
Investment Risk: High relative profitability stocks may perform differently
from the market as a whole and an investment strategy purchasing these securities may cause a fund to
at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company Risk: Securities of small and
mid-cap companies are often less liquid than those of large companies and this could make it difficult
to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap
company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.

risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures contracts, and options thereon, and foreign currency forward contracts, whose value is
derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Liquidity Risk |
Liquidity Risk:
Liquidity risk exists when particular portfolio investments are difficult to purchase
or sell. To the extent that a fund holds illiquid investments, the fund’s performance may be reduced
due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments
may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor
perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that
a fund will experience significant net redemptions at a time when it cannot find willing buyers for its
portfolio securities or can only sell its portfolio securities at a material loss or at increased costs.
Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of
shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade
in lower volumes may be more difficult to value.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its
advisor seek to reduce these operational risks through controls and procedures. However, measures that
seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or its service
providers to suffer data corruption or lose operational functionality.

Risk [Text Block] |
| Principal Risks |
Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.
|
| Risk Lose Money [Member] |
Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money.
|
| Risk Not Insured [Member] |
An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Commodity Risk |
Commodity Risk:
The value of commodity-linked derivative instruments may be affected by changes
in overall market movements, commodity index volatility, changes in interest rates, or factors affecting
a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs,
and international economic, political, and regulatory developments.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as futures, and options thereon, foreign currency forward contracts and swaps, whose value is derived
from that of other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce
risk by offsetting one investment position with another) or non-hedging purposes. While hedging can reduce
or eliminate losses, it also can reduce or eliminate gains or cause losses if the market moves in a manner
different from that anticipated by a fund or if the cost of the derivative outweighs the benefit of
the hedge. In regard to currency hedging, it is generally not possible to precisely
match the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks, including commodity, counterparty, correlation,
interest rate, liquidity, market, credit and management risks, as well as difficulties with respect to
valuation. A fund also may use derivatives for leverage. A fund’s use of derivatives, particularly
commodity-linked derivatives, involves risks different from, or possibly greater than, the risks associated
with investing directly in securities and other traditional investments. Use of leveraged commodity-linked
derivatives creates an opportunity for increased return but, at the same time, creates the possibility
for greater loss (including the likelihood of greater volatility of a fund’s net asset value), and
there can be no assurance that a fund’s use of leverage will be successful. Changes in the value of
a derivative may not correlate perfectly with the underlying asset, rate, or index, and a fund could
lose more than the principal amount invested. For example, potential losses from commodity-linked notes
or swap agreements can be unlimited. Additional risks are associated with the use of credit default swaps,
including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill
its contractual obligations, whether because of bankruptcy or other default), and settlement risk (the
risk faced when one party to a transaction has performed its obligations under a contract but has not
yet received value from its counterparty) and liquidity risk (the possible lack of a secondary market
for the swap agreement). Also, suitable derivative transactions may not be available in all circumstances
and there can be no assurance that a fund will engage in these transactions to reduce exposure to other
risks when that would be beneficial.
|
| Focus Risk |
Focus Risk:
A fund may be exposed, from time to time, to the performance of a small number of commodity sectors (e.g.,
energy, metals or agricultural), which may represent a large portion of a fund. As a result, a fund may
be subject to greater volatility than if a fund were more broadly diversified among commodity sectors.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio hedges foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Interest Rate Risk |
Interest Rate Risk:
Fixed income securities are subject to interest rate risk because the prices of
fixed income securities tend to move in the opposite direction of interest rates. When interest rates
rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund
may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security
prices rise. In general, fixed income securities with longer maturities are more sensitive to changes
in interest rates.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security, or the counterparty to an agreement or contract, including
a derivative instrument, such as a credit default swap, may be unable or unwilling to meet its financial
obligations. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different
degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that
are supported by the full faith and credit of the United States, such as the Federal Housing Administration
and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities
sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from the
U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities
sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie
Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities
issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal
and/or interest.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments at opportune
prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by a
fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market developments.
Liquidity risk includes the risk that a fund will experience significant net redemptions at a time when
it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities
at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market
turmoil or in situations where ownership of shares of a fund are concentrated in one or a few investors.
Investments that are illiquid or that trade in lower volumes may be more difficult to value. Certain
portfolio holdings, such as commodity-linked derivative instruments and swap agreements, may be difficult
or impossible to sell at the time and the price that a fund would like. A Fund may have to lower the
price, sell other holdings instead, or forego an investment opportunity. Any of these could have a negative
effect on management of a fund or the fund's performance.
|
| Subsidiary Risk |
Subsidiary Risk: By investing in the Subsidiary,
the Portfolio is indirectly exposed to the risks associated with the Subsidiary’s investments. The
derivatives and other investments held by the Subsidiary are generally similar to those that are permitted
to be held by the Portfolio and are subject to the same risks that apply to similar investments if held
directly by the Portfolio. These risks are described elsewhere in this Prospectus. There can be no assurance
that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under
the Investment Company Act of 1940, as amended (the “1940 Act”), and, unless otherwise noted in this
Prospectus, is not subject to all of the investor protections of the 1940 Act. However, the Portfolio
wholly owns and controls the Subsidiary, and the Portfolio and the Subsidiary are both managed by the
Advisor, making it unlikely that the Subsidiary will take action contrary to the interests of the Portfolio
and its shareholders. The Board of Directors of DFA Investment Dimensions Group Inc. (the “Fund”)
has oversight responsibility for the investment activities of the Portfolio, including its investment
in the Subsidiary, and the Portfolio’s role as the sole shareholder of the Subsidiary. The Subsidiary
will be subject to investment restrictions and limitations and compliance policies and procedures substantially
similar to those imposed on the Portfolio by the 1940 Act. Changes in the laws of the United States and/or
the Cayman Islands could result in the inability of the Portfolio and/or the Subsidiary to continue to
operate as it does currently and could adversely affect the Portfolio. For example, the Cayman Islands
currently do not impose any income, corporate, or capital gains tax, estate duty, inheritance tax, gift
tax, or withholding tax on the Subsidiary. If Cayman Islands law changes, such that the Subsidiary must
pay Cayman Islands taxes, fund shareholders likely would suffer decreased investment returns.
|
| Tax Risk |
Tax Risk: The tax treatment of commodity-linked
derivative instruments may be adversely affected by changes in legislation, regulations or other legally
binding authority. If, as a result of any such adverse action, the income of a fund from certain commodity-linked
derivatives was treated as non-qualifying income, a fund might fail to qualify as a regulated investment
company and be subject to federal income tax at a fund level. As a regulated investment company, the
Portfolio must derive at least 90% of its gross income for each taxable year from sources treated as
qualifying income under the Internal Revenue Code of 1986, as amended (the “Code”). The Portfolio
has obtained private letter rulings from the Internal Revenue Service confirming that the income the
Portfolio derives from a form of commodity-linked note and the Subsidiary constitutes qualifying income
under the Code. However, the portion of such rulings regarding the treatment of commodity-linked notes
held directly by the Portfolio was revoked because of changes in the IRS’s position. Despite the rulings,
the Portfolio historically has not invested directly in commodity-linked notes. As a result, the Portfolio
may invest in commodity-linked notes only: (a) directly, to the extent that such investments constitute
securities under section 2(a)(36) of the 1940 Act (because such securities generate qualifying income
to a regulated investment company, such as the Portfolio), (b) directly, to the extent that the Portfolio
believes such investments would not prohibit the Portfolio
from qualifying as a regulated investment company regardless of the status of the investment as a security
under section 2(a)(36) of the 1940 Act, or (c) indirectly, as the Portfolio traditionally has done, through
the Subsidiary. If the Portfolio does not appropriately limit such investments or if such investments
(or the income earned on such investments) were to be recharacterized for U.S. tax purposes, the Portfolio
could fail to qualify as a regulated investment company. In lieu of potential disqualification, the Portfolio
is permitted to pay a tax for certain failures to satisfy the income requirement, which, in general,
are limited to those due to reasonable cause and not willful neglect. The Portfolio also may incur transaction
and other costs to comply with any new or additional guidance from the Internal Revenue Service. For
more information, please see the “TAXATION OF THE PORTFOLIO AND ITS SHAREHOLDERS”
section in the Portfolio’s Statement of Additional Information.
|
| Leveraging Risk |
Leveraging Risk: Certain transactions that
a fund may enter into may give rise to a form of leverage. Such transactions may include, among others,
structured notes, swap agreements, futures contracts, and loans of portfolio securities. The use of leverage
may cause a fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy
its obligations. Leverage may cause a fund to be more volatile than if the fund had not been leveraged.
This is because leverage tends to exaggerate the effect of any increase or decrease in the value of a
fund’s portfolio securities.
|
| Regulatory Risk |
Regulatory
Risk: Governments, agencies, or other regulatory bodies may adopt or change laws or
regulations that could adversely affect the issuer, the market value of the security, or a fund’s performance.
|
| Valuation Risk |
Valuation Risk: The lack of an active trading
market may make it difficult to value a security held by a fund. Many commodity-linked derivative instruments
are not actively traded.
|
| Securities Lending Risk |
Securities
Lending Risk: Securities lending involves the risk that the borrower may
fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there
may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover
the securities and/or the value of the collateral falls, including the value of investments made with
cash collateral. Securities lending also may have certain adverse tax consequences.
|
| Operational Risk |
Operational Risk: Operational risks include
human error, changes in personnel, system changes, faults in communication, and failures in systems,
technology, or processes, and the use of artificial intelligence and machine learning (“AI”). Various
operational events or circumstances are outside a fund’s or its advisor’s control, including instances
at third parties. A fund and its advisor seek to reduce these operational risks through controls and
procedures. However, measures that seek to reduce these operational risks through controls and procedures
may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential risks
linked to cyber security breaches of those technological or information systems. Cyber security breaches,
amongst other things, could allow an unauthorized party to gain access to proprietary information, customer
data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose
operational functionality.

and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|

Growth Investment Risk: Growth
stocks may perform differently from the market as a whole and an investment strategy purchasing these

Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these

|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). The Portfolio does not hedge foreign currency risk. Foreign
issuers may not be subject to uniform accounting, auditing and financial reporting standards and there
may be less reliable and publicly available financial and other information about such issuers, as compared
to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing
dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing
legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with
respect to domestic issuers in U.S. courts. Depositary receipts are generally
subject to the same risks as the foreign securities that they evidence or into which they may be converted.
In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.
|
| Geographic Focus Risk |
Geographic
Focus Risk: If a fund focuses its investments
in securities of issuers located in a particular country or region, the fund may be subjected, to a greater
extent than if its investments were less focused, to the risks of volatile economic cycles and/or conditions
and developments that may be particular to that country or region, such as: adverse securities markets;
adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other
developments; or natural disasters.

|
| Small Company Risk |
Small Company
Risk: Securities of small companies are often less liquid than those of large companies
and this could make it difficult to sell a small company security at a desired time or price. As a result,
small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies
are also more vulnerable than larger companies to adverse business or economic developments and they
may have more limited resources.

Fund of Funds
Risk: The investment performance of a fund of funds is affected
by the investment performance of the underlying funds in which the fund of funds invests. The ability
of a fund of funds to achieve its investment objective depends on the ability of the underlying funds
to meet their investment objectives and on the Advisor’s decisions regarding the allocation of a fund
of funds’ assets among the underlying funds. A fund of funds may allocate assets to an underlying fund
or asset class that underperforms other funds or asset classes. There can be no assurance that the investment
objective of a fund of funds or any underlying fund will be achieved. Through its investments in the
underlying funds, a fund of funds is subject to the risks of the underlying funds’ investments. When
a fund of funds invests in underlying funds, investors are exposed to a proportionate share of the expenses
of those underlying funds in addition to the expenses of a fund of funds. Certain risks of the Underlying
Funds’ investments that are principal risks of investing in the Portfolio are described below.
|
| Market Risk |
Market Risk: Even
a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political,
and issuer-specific conditions and events will cause the value of securities, and a fund that owns them,
to rise or fall.
|
| Equity Market Risk |
Equity Market Risk:
Even a long-term investment approach cannot guarantee a profit. Economic, market,
environmental, political, and issuer-specific conditions and events will cause the value of equity securities,
and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices
and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities
and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company
Risk: Securities of small and mid-cap companies are often less liquid
than those of large companies and this could make it difficult to sell a small or mid-cap company security
at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more
in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| Interest Rate Risk |
Interest Rate Risk:
Fixed income securities are subject to interest rate risk because the prices of
fixed income securities tend to move in the opposite direction of interest rates. When interest rates
rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund may
be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security
prices rise. In general, fixed income securities with longer maturities are more sensitive to changes
in interest rates.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P or Fitch or Ba1 or below by Moody’s).
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection: Because
the interest and/or principal payments on an inflation-protected security are adjusted periodically for
changes in inflation, the income distributed by a fund investing in such securities may be irregular.
Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected
securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities
are not protected against deflation. As a result, in a period of deflation, the principal and income
of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such
periods. While inflation-protected securities are expected to be protected from long-term inflationary
trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities.
For example, if interest rates rise due to reasons other than inflation, a fund’s investment in these
securities may not be protected to the extent that the increase is not reflected in the securities’
inflation measures. In addition, positive adjustments to principal generally will result in taxable income
to a fund at the time of such adjustments (which generally would be distributed by the fund as part of
its taxable dividends), even though the principal amount is not paid until maturity. The current market
value of inflation-protected securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent nominal
(stated) interest rates reduced by the expected impact of inflation. Generally, the value of an inflation-protected
security will fall when real interest rates rise and will rise when real interest rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities Tax Risk: Any increase in the principal
amount of an inflation-protected security may be included for tax purposes in a fund’s gross income,
even though no cash attributable to such gross income has been received by a fund. In such event, a fund
may be required to make annual gross distributions to shareholders that exceed the cash it has otherwise
received. In order to pay such distributions, a fund may be required to raise cash by selling its investments.
The sale of such investments could result in capital gains to a fund and additional capital gain distributions
to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed
bond held by a fund may cause amounts previously distributed to shareholders in the taxable year as income
to be characterized as a return of capital, which could increase or decrease a fund’s ordinary income
distributions to shareholders, and may cause some of a fund’s distributed income to be classified as
a return of capital.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among other
reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives
are instruments, such as futures contracts, and options thereon, and foreign currency forward contracts,
whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging
(attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes.
Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will
work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses
if the market moves in a manner different from that anticipated by a fund or if the cost of the derivative
outweighs the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely
match the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments at opportune
prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by a
fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market developments.
Liquidity risk includes the risk that a fund will experience significant net redemptions at a time when
it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities
at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market
turmoil or in situations where ownership of shares of a fund are concentrated in one or a few investors.
Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk:
Operational risks include human error, changes in personnel, system changes, faults
in communication, and failures in systems, technology, or processes, and the use of artificial intelligence
and machine learning (“AI”). Various operational events or circumstances are outside a fund’s or
its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce
these operational risks through controls and procedures. However, measures that seek to reduce these
operational risks through controls and procedures may not address every possible risk and may be inadequate
to address these risks.
|
| Cyber Security Risk |
Cyber Security
Risk: A fund and its service providers’ use of internet, technology
and information systems may expose the fund to potential risks linked to cyber security breaches of those
technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized
party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or
its service providers to suffer data corruption or lose operational functionality.

Fund of Funds Risk:
The investment performance of a fund of funds is affected by the investment performance
of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve
its investment objective depends on the ability of the underlying funds to meet their investment objectives
and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among the underlying
funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms other
funds or asset classes. There can be no assurance that the investment objective of a fund of funds or
any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying

| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose

Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|

entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company
Risk: Securities of small and mid-cap companies are often less liquid
than those of large companies and this could make it difficult to sell a small or mid-cap company security
at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more
in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High
relative profitability stocks may perform differently from the market as a whole and an investment strategy
purchasing these securities may cause a fund to at times underperform equity funds that use other investment
strategies.
|
| Value Investment Risk |
Value Investment Risk:
Value stocks may perform differently from the market as a whole and an investment
strategy purchasing these securities may cause a fund to at times underperform equity funds that use
other investment strategies. Value stocks can react differently to political, economic, and industry
developments than the market as a whole and other types of stocks. Value stocks also may underperform
the market for long periods of time.
|
| Emerging Markets Risk |
Emerging
Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| Interest Rate Risk |
Interest Rate Risk:
Fixed income securities are subject to interest rate risk because the prices of
fixed income securities tend to move in the opposite direction of interest rates. When interest rates
rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund
may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security
prices rise. In general, fixed income securities with longer maturities are more sensitive to changes
in interest rates.
|
| Credit Risk |
Credit Risk: Credit
risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal
when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial
strength may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P or Fitch or Ba1 or below by Moody’s).
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection: Because
the interest and/or principal payments on an inflation-protected security are adjusted periodically for
changes in inflation, the income distributed by a fund investing in such securities may be irregular.
Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected
securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities
are not protected against deflation. As a result, in a period of deflation, the principal and income
of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such
periods. While inflation-protected securities are expected to be protected from long-term inflationary
trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities.
For example, if interest rates rise due to reasons other than inflation, a fund’s investment in these
securities may not be protected to the extent that the increase is not reflected in the securities’
inflation measures. In addition, positive adjustments to principal generally will result in taxable income
to a fund at the time of such adjustments (which generally would be distributed by the fund as part of
its taxable dividends), even though the principal amount is not paid until maturity. The current market
value of inflation-protected securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation.
Generally, the value of an inflation-protected security will fall when real interest rates rise and will
rise when real interest rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected
Securities Tax Risk: Any increase in the principal
amount of an inflation-protected security may be included for tax purposes in a fund’s gross income,
even though no cash attributable to such gross income has been received by a fund. In such event, a fund
may be required to make annual gross distributions to shareholders that exceed the cash it has otherwise
received. In order to pay such distributions, a fund may be required to raise cash by selling its investments.
The sale of such investments could result in capital gains to a fund and additional capital gain distributions
to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed
bond held by a fund may cause amounts previously distributed to shareholders in the taxable year as income
to be characterized as a return of capital, which could increase or decrease a fund’s ordinary income
distributions to shareholders, and may cause some of a fund’s distributed income to be classified as
a return of capital.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among other
reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments at opportune
prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by a
fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market developments.
Liquidity risk includes the risk that a fund will experience significant net redemptions at a time when
it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities
at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market
turmoil or in situations where ownership of shares of a fund are concentrated in one or a few investors.
Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk: Securities lending involves
the risk that the borrower may fail to return the securities in a timely manner or at all. As a result,
a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also
lose money if it does not recover the securities and/or the value of the collateral falls, including
the value of investments made with cash collateral. Securities lending also may have certain adverse
tax consequences.
|
| Operational Risk |
Operational Risk: Operational
risks include human error, changes in personnel, system changes, faults in communication, and failures
in systems, technology, or processes, and the use of artificial intelligence and machine learning (“AI”).
Various operational events or circumstances are outside a fund’s or its advisor’s control, including
instances at third parties. A fund and its advisor seek to reduce these operational risks through controls
and procedures. However, measures that seek to reduce these operational risks through controls and procedures
may not address every possible risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A fund and its service
providers’ use of internet, technology and information systems may expose the fund to potential risks
linked to cyber security breaches of those technological or information systems. Cyber security breaches,
amongst other things, could allow an unauthorized party to gain access to proprietary information, customer
data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose
operational functionality.

Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The
following is a description of principal risks of investing in the Portfolio.

|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions
regarding the allocation of a fund of funds’ assets among the underlying funds.
A fund of funds may allocate assets to an underlying fund or asset class that underperforms other funds
or asset classes. There can be no assurance that the investment objective of a fund of funds or any
underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds is
subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are principal
risks of investing in the Portfolio are described below.
|
| Market Risk |
Market
Risk: Even a long-term investment approach cannot guarantee a profit.
Economic, market, environmental, political, and issuer-specific conditions and events will cause the
value of securities, and a fund that owns them, to rise or fall.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole

have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed
income securities are subject to interest rate risk because the prices of fixed income securities tend
to move in the opposite direction of interest rates. When interest rates rise, fixed income security
prices fall. During periods of very low or negative interest rates, a fund may be subject to a greater
risk of rising interest rates. When interest rates fall, fixed income security prices rise. In general,
fixed income securities with longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P or Fitch or Ba1 or below by Moody’s).
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection: Because
the interest and/or principal payments on an inflation-protected security are adjusted periodically for
changes in inflation, the income distributed by a fund investing in such securities may be irregular.
Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected
securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities
are not protected against deflation. As a result, in a period of deflation, the principal and income
of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such
periods. While inflation-protected securities are expected to be protected from long-term inflationary
trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities.
For example, if interest rates rise due to reasons other than inflation, a fund’s investment in
these securities may not be protected to the extent that the increase is not reflected in the securities’
inflation measures. In addition, positive adjustments to principal generally will result in taxable income
to a fund at the time of such adjustments (which generally would be distributed by the fund as part of
its taxable dividends), even though the principal amount is not paid until maturity. The current market
value of inflation-protected securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities
Tax Risk: Any increase in the principal amount of an inflation-protected
security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital, which could increase or decrease a fund’s ordinary income distributions
to shareholders, and may cause some of a fund’s distributed income to be classified as a return
of capital.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following is a description of principal
risks of investing in the Portfolio.

|
| Fund of Funds Risk |
Fund of Funds
Risk: The investment performance of a fund of funds is affected
by the investment performance of the underlying funds in which the fund of funds invests. The ability
of a fund of funds to achieve its investment objective depends on the ability of the underlying funds
to meet their investment objectives and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among the underlying
funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms other
funds or asset classes. There can be no assurance that the investment objective of a fund of funds or
any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are
principal risks of investing in the Portfolio are described below.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.

and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company
Risk: Securities of small and mid-cap companies are often less liquid
than those of large companies and this could make it difficult to sell a small or mid-cap company security
at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more
in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability

the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest.Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P Global Ratings ("S&P") or Fitch Ratings Ltd. ("Fitch") or Ba1 or below by
Moody's Ratings ("Moody's")).

| Risks of Investing for Inflation Protection |
Risks of Investing
for Inflation Protection: Because the interest and/or
principal payments on an inflation-protected security are adjusted periodically for changes in inflation,
the income distributed by a fund investing in such securities may be irregular. Although the U.S. Treasury
guarantees to pay at maturity at least the original face value of any inflation-protected securities
the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities are
not protected against deflation. As a result, in a period of deflation, the principal and income of inflation-protected
securities held by a fund will decline and the fund may suffer a loss during such periods. While inflation-protected
securities are expected to be protected from long-term inflationary trends, short-term increases in inflation
may lead to a decline in the value of a fund holding such securities. For example, if interest rates
rise due to reasons other than inflation, a fund’s investment in these securities may not be protected
to the extent that the increase is not reflected in the securities’ inflation measures. In addition,
positive adjustments to principal generally will result in taxable income to a fund at the time of such
adjustments (which generally would be distributed by the fund as part of its taxable dividends), even
though the principal amount is not paid until maturity. The current market value of inflation-protected
securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected
Securities Interest Rate Risk: Inflation-protected securities
may react differently from other fixed income securities to changes in interest rates. Because interest
rates on inflation-protected securities are adjusted for inflation, the values of these securities are
not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities
Tax Risk: Any increase in the principal amount of an inflation-protected
security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital, which could increase or decrease a fund’s ordinary income distributions
to shareholders, and may cause some of a fund’s distributed income to be classified as a return
of capital.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Principal Risks Because
the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.
An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. The following is a description of principal
risks of investing in the Portfolio.

An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds
Risk: The investment performance of a fund of funds is affected
by the investment performance of the underlying funds in which the fund of funds invests. The ability
of a fund of funds to achieve its investment objective depends on the ability of the underlying funds
to meet their investment objectives and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among the underlying
funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms other
funds or asset classes. There can be no assurance that the investment objective of a fund of funds or
any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are
principal risks of investing in the Portfolio are described below.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|

approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company
Risk: Securities of small and mid-cap companies are often less liquid
than those of large companies and this could make it difficult to sell a small or mid-cap company security
at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more
in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react
differently to political, economic, and industry developments than the market as a whole and other types
of stocks. Value stocks also may underperform the market for long periods of time.
|
| Emerging Markets Risk |
Emerging Markets Risk: Securities of issuers associated
with emerging market countries may be subject to higher and additional risks than securities of issuers
in developed foreign markets. Numerous emerging market countries
have a history of, and continue to experience serious, and potentially continuing, economic and political
problems. Stock markets in many emerging market countries are relatively small, expensive to trade in
and generally have
higher risks than those in developed markets. Securities in emerging markets also
may be less liquid than those in developed markets and foreigners are often limited in their ability
to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other
conditions. Frontier market countries generally have smaller economies or less developed capital markets
and, as a result, the risks of investing in emerging market countries are magnified in frontier market
countries.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed
income securities are subject to interest rate risk because the prices of fixed income securities tend
to move in the opposite direction of interest rates. When interest rates rise, fixed income security
prices fall. During periods of very low or negative interest rates, a fund may be subject to a greater
risk of rising interest rates. When interest rates fall, fixed income security prices rise. In general,
fixed income securities with longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P or Fitch or Ba1 or below by Moody’s).
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection: Because
the interest and/or principal payments on an inflation-protected security are adjusted periodically for
changes in inflation, the income distributed by a fund investing in such securities may be irregular.
Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected
securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities
are not protected against deflation. As a result, in a period of deflation, the principal and income
of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such
periods. While inflation-protected securities are expected to be protected from long-term inflationary
trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities.
For example, if interest rates rise due to reasons other than inflation, a fund’s investment in
these securities may not be protected to the extent that the increase is not reflected in the securities’
inflation measures. In addition, positive adjustments to principal generally will result in taxable income
to a fund at the time of such adjustments (which generally would be distributed by the fund as part of

| Derivatives Risk |
Derivatives
Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon,
and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices.
Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position
with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no
guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also

hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign
currency forward contracts to the value of the securities involved due to fluctuations in the market
values of such securities and cash flows into and out of a fund between the date a foreign currency forward

value of inflation-protected securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent
nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of
an inflation-protected security will fall when real interest rates rise and will rise when real interest
rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected Securities
Tax Risk: Any increase in the principal amount of an inflation-protected
security may be included for tax purposes in a fund’s gross income, even though no cash attributable
to such gross income has been received by a fund. In such event, a fund may be required to make annual
gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such
distributions, a fund may be required to raise cash by selling its investments. The sale of such investments
could result in capital gains to a fund and additional capital gain distributions to shareholders. In
addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund
may cause amounts previously distributed to shareholders in the taxable year as income to be characterized
as a return of capital, which could increase or decrease a fund’s ordinary income distributions
to shareholders, and may cause some of a fund’s distributed income to be classified as a return
of capital.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.

Principal
Risks Because the value of your investment in the Portfolio will fluctuate, there is
the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description
of principal risks of investing in the Portfolio.

|
| Risk Not Insured [Member] |
An investment in the Portfolio is not a deposit of a bank and is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund
of Funds Risk: The investment performance
of a fund of funds is affected by the investment performance of the underlying funds in which the fund
of funds invests. The ability of a fund of funds to achieve its investment objective depends on the ability
of the underlying funds to meet their investment objectives and on the Advisor’s decisions regarding
the allocation of a fund of funds’ assets among the underlying funds. A fund of funds may allocate
assets to an underlying fund or asset class that underperforms other funds or asset classes. There can
be no assurance that the investment objective of a fund of funds or any underlying fund will be achieved.
Through its investments in the underlying funds, a fund of funds is subject to the risks of the underlying
funds’ investments. When a fund of funds invests in underlying funds, investors are exposed to
a proportionate share of the expenses of those underlying funds in addition to the expenses of a fund
of funds. Certain risks of the Underlying Funds’ investments that are principal risks of investing
in the Portfolio are described below.
|
| Equity Market Risk |
Equity
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Market Risk |
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company
Risk: Securities of small and mid-cap companies are often less liquid
than those of large companies and this could make it difficult to sell a small or mid-cap company security
at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more
in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High relative profitability
stocks may perform differently from the market as a whole and an investment strategy purchasing these
securities may cause a fund to at times underperform equity funds that use other investment strategies.
|
| Value Investment Risk |
Value Investment Risk: Value stocks may perform
differently from the market as a whole and an investment strategy purchasing these securities may cause
a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry
developments than the market as a whole and other types of stocks. Value stocks also may underperform
the market for long periods of time.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P or Fitch or Ba1 or below by Moody’s).
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection: Because
the interest and/or principal payments on an inflation-protected security are adjusted periodically for
changes in inflation, the income distributed by a fund investing in such securities may be irregular.
Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected
securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities
are not protected against deflation. As a result, in a period of deflation, the principal and income
of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such
periods. While inflation-protected securities are expected to be protected from long-term inflationary
trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities.
For example, if interest rates rise due to reasons other than inflation, a fund’s investment in
these securities may not be protected to the extent that the increase is not reflected in the securities’
inflation measures. In addition, positive adjustments to principal generally will result in taxable income
to a fund at the time of such adjustments (which generally would be distributed by the fund as part of
its taxable dividends), even though the principal amount is not paid until maturity. The current market
value of inflation-protected securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected

that falling interest rates will cause a fund’s income to decline because, among other reasons,
the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding
securities.

risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.

Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose

hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a

use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.

|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.
|
| Derivatives Risk |
Derivatives Risk: Derivatives are instruments,
such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, whose
value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting
to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with
derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While
hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the
market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs
the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match
the foreign currency exposure of such foreign currency forward contracts to the value of the securities
involved due to fluctuations in the market values of such securities and cash flows into and out of a
fund between the date a foreign currency forward contract is entered into and the date it expires. The
use of derivatives for non-hedging purposes may be considered to carry more risk than other types of
investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives.
Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity,
interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.
|
| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk:
Securities lending involves the risk that the borrower may fail to return the securities in a timely
manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned
securities. A fund could also lose money if it does not recover the securities and/or the value of the
collateral falls, including the value of investments made with cash collateral. Securities lending also
may have certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber Security Risk: A
fund and its service providers’ use of internet, technology and information systems may expose
the fund to potential risks linked to cyber security breaches of those technological or information systems.
Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary
information, customer data, or fund assets, or cause the fund and/or its service providers to suffer
data corruption or lose operational functionality.

Principal Risks Because the value of your
investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency. The following is a description of principal risks of investing
in the Portfolio.

An investment
in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.
|
| Fund of Funds Risk |
Fund of Funds Risk:
The investment performance of a fund of funds is affected by the investment performance
of the underlying funds in which the fund of funds invests. The ability of a fund of funds to achieve
its investment objective depends on the ability of the underlying funds to meet their investment objectives
and on the Advisor’s decisions regarding the allocation of a fund of funds’ assets among
the underlying funds. A fund of funds may allocate assets to an underlying fund or asset class that underperforms
other funds or asset classes. There can be no assurance that the investment objective of a fund of funds
or any underlying fund will be achieved. Through its investments in the underlying funds, a fund of funds
is subject to the risks of the underlying funds’ investments. When a fund of funds invests in underlying
funds, investors are exposed to a proportionate share of the expenses of those underlying funds in addition
to the expenses of a fund of funds. Certain risks of the Underlying Funds’ investments that are
principal risks of investing in the Portfolio are described below.
|
| Equity Market Risk |
Equity Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock
markets are volatile, with periods of rising prices and periods of falling prices.
|
| Market Risk |
Market Risk: Even a long-term investment
approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions
and events will cause the value of securities, and a fund that owns them, to rise or fall.
|
| Foreign Securities and Currencies Risk |
Foreign Securities and Currencies Risk: Foreign securities prices
may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or
(b) less regulated or liquid securities markets. Investors holding these securities may also be exposed
to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S.
dollar or that a foreign government will convert, or be forced to convert, its currency to another currency,
changing its value against the U.S. dollar). Foreign issuers may not
be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable
and publicly available financial and other information about such issuers, as compared to U.S. issuers.
A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends
and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal
remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect
to domestic issuers in U.S. courts.
|
| Foreign Government Debt Risk |
Foreign Government
Debt Risk: The risk that: (a) the governmental entity that controls the
repayment of government debt may not be willing or able to repay the principal and/or to pay the interest
when it becomes due, due to factors such as political considerations, the relative size of the governmental
entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency
reserves, the failure to put in place economic reforms required by the International Monetary Fund or
other multilateral agencies, and/or other national economic factors; (b) governments may default on their
debt securities, which may require holders of such securities to participate in debt rescheduling; and
(c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole
or in part.
|
| Small and Mid-Cap Company Risk |
Small and Mid-Cap Company
Risk: Securities of small and mid-cap companies are often less liquid
than those of large companies and this could make it difficult to sell a small or mid-cap company security
at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more
in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies
to adverse business or economic developments and they may have more limited resources.
|
| Profitability Investment Risk |
Profitability Investment Risk: High
relative profitability stocks may perform differently from the market as a whole and an investment strategy
purchasing these securities may cause a fund to at times underperform equity funds that use other investment
strategies.
|
| Value Investment Risk |
Value Investment Risk:
Value stocks may perform differently from the market as a whole and an investment
strategy purchasing these securities may cause a fund to at times underperform equity funds that use
other investment strategies. Value stocks can react differently to political, economic, and industry
developments than the market as a whole and other types of stocks. Value stocks also may underperform
the market for long periods of time.
|
| Emerging Markets Risk |
Emerging Markets
Risk: Securities of issuers associated with emerging market countries
may be subject to higher and additional risks than securities of issuers in developed foreign markets.
Numerous emerging market countries have a history of, and continue to experience
serious, and potentially continuing, economic and political problems. Stock markets in many emerging
market countries are relatively small, expensive to trade in and generally have higher risks than those
in developed markets. Securities in emerging markets also may be less liquid than those in developed
markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these
markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally
have smaller economies or less developed capital markets and, as a result, the risks of investing in
emerging market countries are magnified in frontier market countries.
|
| Interest Rate Risk |
Interest Rate Risk: Fixed income securities
are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite
direction of interest rates. When interest rates rise, fixed income security prices fall. During periods
of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates.
When interest rates fall, fixed income security prices rise. In general, fixed income securities with
longer maturities are more sensitive to changes in interest rates.
|
| Credit Risk |
Credit Risk: Credit risk is the risk
that the issuer of a security may be unable to make interest payments and/or repay principal when due.
A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength
may affect a security’s value, and thus, impact the performance of a fund holding such securities.
Government agency obligations have different levels of credit support and, therefore, different degrees
of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported
by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie
Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored
by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury,
subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by
the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and
Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued
or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or
interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g.,
BB+ or below by S&P or Fitch or Ba1 or below by Moody’s).
|
| Risks of Investing for Inflation Protection |
Risks of Investing for Inflation Protection: Because
the interest and/or principal payments on an inflation-protected security are adjusted periodically for
changes in inflation, the income distributed by a fund investing in such securities may be irregular.
Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected
securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities
are not protected against deflation. As a result, in a period of deflation, the principal and income
of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such
periods. While inflation-protected securities are expected to be protected from long-term inflationary
trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities.
For example, if interest rates rise due to reasons other than inflation, a fund’s investment in
these securities may not be protected to the extent that the increase is not reflected in the securities’
inflation measures. In addition, positive adjustments to principal generally will result in taxable income
to a fund at the time of such adjustments (which generally would be distributed by the fund as part of
its taxable dividends), even though the principal amount is not paid until maturity. The current market
value of inflation-protected securities is not guaranteed and will fluctuate.
|
| Inflation-Protected Securities Interest Rate Risk |
Inflation-Protected Securities Interest Rate Risk: Inflation-protected
securities may react differently from other fixed income securities to changes in interest rates. Because
interest rates on inflation-protected securities are adjusted for inflation, the values of these securities
are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities
are anticipated to change in response to changes in “real” interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation.
Generally, the value of an inflation-protected security will fall when real interest rates rise and will
rise when real interest rates fall.
|
| Inflation-Protected Securities Tax Risk |
Inflation-Protected
Securities Tax Risk: Any increase in the principal
amount of an inflation-protected security may be included for tax purposes in a fund’s gross income,
even though no cash attributable to such gross income has been received by a fund. In such event, a fund
may be required to make annual gross distributions to shareholders that exceed the cash it has otherwise
received. In order to pay such distributions, a fund may be required to raise cash by selling its investments.
The sale of such investments could result in capital gains to a fund and additional capital gain distributions
to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed
bond held by a fund may cause amounts previously distributed to shareholders in the taxable year as income
to be characterized as a return of capital, which could increase or decrease a fund’s ordinary
income distributions to shareholders, and may cause some of a fund’s distributed income to be classified
as a return of capital.
|
| Income Risk |
Income Risk: Income
risk is the risk that falling interest rates will cause a fund’s income to decline because, among
other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in
lower-yielding securities.
|
| Call Risk |
Call Risk: Call
risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding
fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities
with lower interest rates than the original obligations.

to the same risks as the foreign securities that they evidence or into which they may be converted. In
addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered
depositary receipts, are under no obligation to distribute shareholder communications to the holders
of such receipts, or to pass through to them any voting rights with respect to the deposited securities.
Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily
available public information about the issuer.

interest rate, market, credit and management risks, as well as difficulties with respect to valuation.
Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index,
and a fund could lose more than the principal amount invested. Additional risks are associated with the
use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement
will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity
risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund
is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition,
where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune
times in order to meet payment obligations. Swaps may be illiquid or difficult to value.

| Liquidity Risk |
Liquidity Risk: Liquidity risk exists when
particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid
investments, the fund’s performance may be reduced due to an inability to sell the investments
at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase
by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market
developments. Liquidity risk includes the risk that a fund will experience significant net redemptions
at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio
securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods
of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few
investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.
|
| Securities Lending Risk |
Securities Lending Risk: Securities
lending involves the risk that the borrower may fail to return the securities in a timely manner or at
all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities.
A fund could also lose money if it does not recover the securities and/or the value of the collateral
falls, including the value of investments made with cash collateral. Securities lending also may have
certain adverse tax consequences.
|
| Operational Risk |
Operational
Risk: Operational risks include human error, changes in personnel,
system changes, faults in communication, and failures in systems, technology, or processes, and the use
of artificial intelligence and machine learning (“AI”). Various operational events or circumstances
are outside a fund’s or its advisor’s control, including instances at third parties. A fund
and its advisor seek to reduce these operational risks through controls and procedures. However, measures
that seek to reduce these operational risks through controls and procedures may not address every possible
risk and may be inadequate to address these risks.
|
| Cyber Security Risk |
Cyber
Security Risk: A fund and its service providers’
use of internet, technology and information systems may expose the fund to potential risks linked to
cyber security breaches of those technological or information systems. Cyber security breaches, amongst
other things, could allow an unauthorized party to gain access to proprietary information, customer data,
or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational
functionality.
