may incur losses due to declines in one or more markets in which it invests. These declines may be the 
result of, among other things, political, regulatory, market, economic or social developments affecting 
the relevant market(s). To the extent that such developments impact specific industries, market sectors, 
countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market sectors, 
countries and/or geographic regions can be expected to be particularly affected, especially if such investments 
are a significant portion of its investment portfolio. In addition, turbulence in financial markets and 
reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which 
could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, 
and conditions and events in one country, region or financial market may adversely impact issuers worldwide. 
As a result, local, regional or global events such as war or military conflict, acts of terrorism, the 
spread of infectious illness or other public health issues, social unrest, natural disasters, extreme 
weather, other geological events, man-made disasters, supply chain disruptions, deflation, inflation, 
government defaults, government shutdowns, the imposition of sanctions or other similar measures, recessions 
or other events could have a significant negative impact on global economic and market conditions. For 
example, a public health or other emergency and aggressive responses taken by many governments or voluntarily 
imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines 
or similar restrictions, as well as the closure of, or operational changes to, many retail and other 
businesses, may have severe negative impacts on markets worldwide. Additionally, general market conditions 
may affect the value of a Portfolio&#x2019;s securities, including changes in interest rates, currency 
rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency restrictions 
or similar actions (or retaliatory measures taken in response to such actions), or the threat or potential 
of one or more such events and developments, could lead to price volatility and overall declines in the 
US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic structures that are less diverse and mature, and political systems that are less stable, than 
those of developed countries. The economies of countries with emerging markets may be based predominantly 
on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and 
may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities 
of issuers located in certain emerging countries involve the risk of loss resulting from problems in 
share registration, settlement or custody, substantial economic, political and social disruptions and 
the imposition of sanctions or exchange controls (including repatriation restrictions). The securities 
markets of emerging market countries have historically been extremely volatile and less liquid than more 
developed markets. These market conditions may continue or worsen. Investments in these countries may 
be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging 
market currencies against the US dollar may occur subsequent to acquisition of investments denominated

Manager utilizes a flexible, core investment approach and engages in bottom-up, fundamental security 
analysis and selection. The Portfolio may invest in securities across the capitalization spectrum, although 
it typically invests in securities of companies with a market capitalization of $300 million or more. 
Implementation of the Portfolio&#x2019;s investment strategy may, during certain periods, result in the 
investment of a significant portion of the Portfolio&#x2019;s assets in a particular market sector and/or 
a particular country.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The allocation of the Portfolio&#x2019;s assets among countries and regions may 
vary from time to time based on the Investment Manager&#x2019;s judgment and its analysis of market conditions. 
Emerging market countries include all countries not represented by the MSCI World Index. Under normal 
circumstances, the Portfolio invests at least 80% of its assets in equity securities of companies that 
are economically tied to emerging market countries. In addition to common stocks, such equity securities 
also may include American Depositary Receipts (&#x201c;ADRs&#x201d;), Global Depositary Receipts and European 
Depositary Receipts.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

may incur losses due to declines in one or more markets in which it invests. These declines may be the 
result of, among other things, political, regulatory, market, economic or social developments affecting 
the relevant market(s). To the extent that such developments impact specific industries, market sectors, 
countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market sectors, 
countries and/or geographic regions can be expected to be particularly affected, especially if such investments 
are a significant portion of its investment portfolio. In addition, turbulence in financial markets and 
reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which 
could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, 
and conditions and events in one country, region or financial market may adversely impact issuers worldwide. 
As a result, local, regional or global events such as war or military conflict, acts of terrorism, the 
spread of infectious illness or other public health issues, social unrest, natural disasters, extreme 
weather, other geological events, man-made disasters, supply chain disruptions, deflation, inflation, 
government defaults, government shutdowns, the imposition of sanctions or other similar measures, recessions 
or other events could have a significant negative impact on global economic and market conditions. For 
example, a public health or other emergency and aggressive responses taken by many governments or voluntarily 
imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines 
or similar restrictions, as well as the closure of, or operational changes to, many retail and other 
businesses, may have severe negative impacts on markets worldwide. Additionally, general market conditions 
may affect the value of a Portfolio&#x2019;s securities, including changes in interest rates, currency 
rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency restrictions 
or similar actions (or retaliatory measures taken in response to such actions), or the threat or potential 
of one or more such events and developments, could lead to price volatility and overall declines in the 
US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries 
and companies in which the Portfolio invests. Non-US securities carry special risks, such as less developed 
or less efficient trading markets, political instability, a lack of company information, differing auditing 
and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;settlement 
or asset&#160;custody, which could, among other things, effectively restrict or eliminate the Portfolio&#x2019;s 
ability to purchase or sell certain foreign securities. To the extent the Portfolio holds securities 
subject to such actions, the securities may become difficult to value and/or less liquid (or illiquid). 
In some cases, the securities may become worthless.  &lt;/p&gt;</rr:RiskTextBlock>

countries generally have economic structures that are less diverse and mature, and political systems 
that are less stable, than those of developed countries. The economies of countries with emerging markets 
may be based predominantly on only a few industries, may be highly vulnerable to changes in local or 
global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to political, economic, legal, market and currency risks. Significant devaluation 
of emerging market currencies against the US dollar may occur subsequent to acquisition of investments 
denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may incur losses due to declines in one or more markets in which it invests. These declines may be the 
result of, among other things, political, regulatory, market, economic or social developments affecting 
the relevant market(s). To the extent that such developments impact specific industries, market sectors, 
countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market sectors, 
countries and/or geographic regions can be expected to be particularly affected, especially if such investments 
are a significant portion of its investment portfolio. In addition, turbulence in financial markets and 
reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which 
could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, 
and conditions and events in one country, region or financial market may adversely impact issuers worldwide. 
As a result, local, regional or global events such as war or military conflict, acts of terrorism, the 
spread of infectious illness or other public health issues, social unrest, natural disasters, extreme 
weather, other geological events, man-made disasters, supply chain disruptions, deflation, inflation, 
government defaults, government shutdowns, the imposition of sanctions or other similar measures, recessions 
or other events could have a significant negative impact on global economic and market conditions. For 
example, a public health or other emergency and aggressive responses taken by many governments or voluntarily 
imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines 
or similar restrictions, as well as the closure of, or operational changes to, many retail and other 
businesses, may have severe negative impacts on markets worldwide. Additionally, general &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;market 
conditions may affect the value of a Portfolio&#x2019;s securities, including changes in interest rates, 
currency rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency 
restrictions or similar actions (or retaliatory measures taken in response to such actions), or the threat 
or potential of one or more such events and developments, could lead to price volatility and overall 
declines in the US and global investment markets.&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries 
and companies in which the Portfolio invests. Non-US securities carry special risks, such as less developed 
or less efficient trading markets, political instability, a lack of company information, differing auditing 
and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Emerging market countries generally have economic structures that are less diverse and mature, and political 
systems that are less stable, than those of developed countries. The economies of countries with emerging 
markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local 
or global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to political, economic, legal, market and currency risks. Significant devaluation 
of emerging market currencies against the US dollar may occur subsequent to acquisition of investments 
denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

of the Portfolio&#x2019;s investment strategy may, during certain periods, result in the investment of 
a significant portion of the Portfolio&#x2019;s assets in a particular country, such as China, and the 
Portfolio would be expected to be affected by political, regulatory, market, economic and social developments 
affecting that country. There are special risks associated with investments in China, including currency 
fluctuations, less liquidity, expropriation, confiscatory taxation, nationalization, exchange control 
regulations (including currency blockage), trading halts, limitations on repatriation and differing legal 
standards. Strained relations between the United States and China have heightened concerns of increased 
tariffs and restrictions on trade between the two countries, such as the potential for an escalation 
in trade tensions. An increase in tariffs or trade restrictions (and threats thereof) could lead to a 
significant reduction in international trade, which could have a negative impact on China&#x2019;s export 
industry, Chinese issuers, the liquidity or price of the Portfolio&#x2019;s direct or indirect investments 
in China and, therefore, the Portfolio.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The economy of China differs, often unfavorably, 
from the US economy in such respects as structure, general development, government involvement, wealth 
distribution, rate of inflation, growth rate, interest rates, allocation of resources and capital reinvestment, 
among others. The Chinese central government has historically exercised&#160;substantial control over 
virtually every sector of the Chinese&#160;economy through administrative regulation and/or state ownership 
or other involvement and actions of the Chinese central and local government authorities continue to 
have a substantial effect on economic conditions in China. In addition, the Chinese government has from 
time to time actively intervened in Chinese companies&#x2019; operations and structures and taken actions 
that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate 
in particular industries, induce mergers between companies in certain industries and induce private companies 
to publicly offer their securities to increase or continue the rate of economic growth, control the rate 
of inflation or otherwise regulate economic expansion. The Chinese government may do so in the future 
as well, potentially having a significant adverse effect on economic conditions in China. Moreover, strained 
relations, border disputes or other conflict between China and neighboring countries could adversely 
affect the Chinese economy.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may obtain exposure to companies based or operated in China by investing 
through legal structures known as variable interest entities (&#x201c;VIEs&#x201d;). Instead of directly 
owning the equity securities of a Chinese company, a VIE enters into service and other contracts with 
the Chinese company. Although the VIE has no equity ownership of the Chinese company, the contractual 
arrangements permit the VIE to consolidate the Chinese company into its financial statements. VIE investments 
are subject to the risk that any breach of these contractual arrangements will be subject to Chinese 
law and jurisdiction, that Chinese law may be interpreted or change in a way that affects the enforceability 
of the VIE&#x2019;s arrangements, or that contracts between the Chinese company and the VIE may otherwise 
not be enforceable under Chinese law. VIE structures also could face delisting or other ramifications 
for failure to meet the requirements of the Securities and Exchange Commission, the Public Company Accounting 
Oversight Board or other United States regulators. If any of these or similar risks or &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;developments 
materialize, the value of investments in VIEs could be adversely affected and the Portfolios could incur 
significant losses with no recourse available. A decline or worsening in diplomatic or other relations 
between the US and China could increase the risks associated with the VIE structure.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may 
invest in eligible renminbi-denominated class A shares of equity securities that are listed and traded 
on certain Chinese stock exchanges (&#x201c;China A-Shares&#x201d;) through Hong Kong Stock Connect Program 
(&#x201c;Stock Connect&#x201d;). While Stock Connect is not subject to individual investment quotas, daily 
and aggregate investment quotas apply to all Stock Connect participants, which may restrict or preclude 
the Portfolio&#x2019;s ability to invest in China A-Shares (although the Portfolio would be permitted 
to sell China A-Shares regardless of the quota balance). Stock Connect is also subject to trading, clearance, 
settlement and operational risks. &lt;/p&gt;</rr:RiskTextBlock>

securities, principally common stocks, of emerging markets companies. In managing the Portfolio, the 
Investment Manager utilizes a quantitatively driven, bottom up stock selection process. The Portfolio 
management team selects investments for the Portfolio from a broad investment universe of emerging market 
stocks and depositary receipts, including American Depositary Receipts (&#x201c;ADRs&#x201d;), Global Depositary 
Receipts and European Depositary Receipts, real estate investment trusts (&#x201c;REITs&#x201d;), warrants 
and rights. The active, quantitative approach utilized by the Portfolio management team involves initial 
screening, risk assessment and evaluation of each company relative to its global peers. The Investment 
Manager uses an objective, systematic investment process that blends both risk and stock ranking assessments 
designed to capture attractive risk-to-return characteristics. In addition to a multidimensional assessment 
of risk, each company is evaluated daily according to four independent measures: growth, value, sentiment 
and quality. The Portfolio may invest across the capitalization spectrum.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Under normal circumstances,

tied to emerging market countries. The allocation of the Portfolio&#x2019;s assets among countries and 
regions will vary from time to time based on the Investment Manager&#x2019;s judgment and its analysis 
of market conditions. Implementation of the Portfolio&#x2019;s investment strategy may, during certain

of such company are traded principally in emerging markets countries; or (iii) during the most recent 
fiscal year of the company, the company derived at least 50% of its revenues or profits from goods produced 
or sold, investments made, or services performed in emerging markets countries or that has at least 50%

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets 
are increasingly interconnected, and conditions and events in one country, region or financial market 
may adversely impact issuers worldwide. As a result, local, regional or global events such as war or 
military conflict, acts of terrorism, the spread of infectious illness or other public health issues, 
social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply 
chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of 
sanctions or other similar measures, recessions or other events could have a significant negative impact 
on global economic and market conditions. For example, a public health or other emergency and aggressive 
responses taken by many governments or voluntarily imposed by private parties, including closing borders, 
restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure 
of, or operational changes to, many retail and other businesses, may have severe negative impacts on 
markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;rates 
or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency restrictions 
or similar actions (or retaliatory measures taken in response to such actions), or the threat or potential 
of one or more such events and developments, could lead to price volatility and overall declines in the 
US and global investment markets.&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries 
and companies in which the Portfolio invests. Non-US securities carry special risks, such as less developed 
or less efficient trading markets, political instability, a lack of company information, differing auditing 
and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Emerging market countries generally have economic structures that are less diverse and mature, and political 
systems that are less stable, than those of developed countries. The economies of countries with emerging 
markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local 
or global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to political, economic, legal, market and currency risks. Significant devaluation 
of emerging market currencies against the US dollar may occur subsequent to acquisition of investments 
denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

A quantitative model, such as the risk and other &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;models 
used by the Investment Manager requires adherence to a systematic, disciplined process. The Investment 
Manager&#x2019;s ability to monitor and, if necessary, adjust its quantitative model could be adversely 
affected by various factors including incorrect or outdated market and other data inputs. Factors that 
affect a security&#x2019;s value can change over time, and these changes may not be reflected in the quantitative 
model. In addition, factors used in quantitative analysis and the weight placed on those factors may 
not be predictive of a security&#x2019;s value.&lt;/p&gt;</rr:RiskTextBlock>

Small and mid cap companies carry additional risks because their earnings tend to be less predictable, 
their share prices more volatile and their securities less liquid than larger, more established companies. 
The shares of small and mid cap companies tend to trade less frequently than those of larger companies, 
which can have an adverse effect on the pricing of these securities and on the ability to sell these 
securities when the Investment Manager deems it appropriate.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

REITs are subject to similar risks as an investment in a realty-related company. Consequently, investments 
in REITs could lead to investment results that may be significantly different from investments in the 
broader securities markets. The risks related to investments in realty-related companies include, but 
are not limited to: adverse changes in general economic and local market conditions; adverse developments 
in employment; changes in supply or demand for similar or competing properties; unfavorable changes in 
applicable taxes, governmental regulations and interest rates; operating or development expenses; and 
lack of available financing. Due to certain special considerations that apply to REITs, investments in 
REITs may carry additional risks not necessarily present in investments in other securities. REIT securities 
(including those trading on national exchanges) typically have trading volumes that are less than those 
of securities of other types of companies, which may affect the Portfolio&#x2019;s ability to trade or 
liquidate those securities. An investment in a REIT may be adversely affected if the REIT fails to comply 
with applicable laws and regulations, including failing to qualify as a REIT under the Internal Revenue 
Code of 1986, as amended. Failure to qualify with any of these requirements could jeopardize a company&#x2019;s 
status as a REIT. The Portfolio generally will have no control over the operations and policies of a 
REIT, including qualification as a REIT.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may trade at prices that vary from their net asset values, sometimes significantly. The shares of ETFs 
may trade at prices at, below or above their net asset value. In addition, the performance of an ETF 
pursuing a passive index-based strategy may diverge from the performance of the index. The Portfolio&#x2019;s 
investments in ETFs are subject to the risks of the ETFs&#x2019; investments, as well as to the general 
risks of investing in ETFs. The Portfolio will bear not only the Portfolio&#x2019;s management fees and 
operating expenses, but also the Portfolio&#x2019;s proportional share of the management fees and operating 
expenses of the ETFs in which the Portfolio invests. Although Section 12 of the Investment Company Act 
of 1940, as amended (the &#x201c;1940 Act&#x201d;) limits the amount of the Portfolio&#x2019;s assets that 
may be invested in one or more ETFs, Rule 12d1-4 under the 1940 Act allows the Portfolio to acquire the 
securities of another investment company, including ETFs, in excess of the limitations imposed by Section 
12 of the 1940 Act, subject to certain limitations and conditions. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may, during certain periods, result in the investment of a significant portion of the Portfolio&#x2019;s 
assets in a particular country, such as China, and the Portfolio would be expected to be affected by 
political, regulatory, market, economic and social developments affecting that country. There are special 
risks associated with investments in China, including currency fluctuations, less &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;liquidity, 
expropriation, confiscatory taxation, nationalization, exchange control regulations (including currency 
blockage), trading halts, limitations on repatriation and differing legal standards. Strained relations 
between the United States and China have heightened concerns of increased tariffs and restrictions on 
trade between the two countries, such as the potential for an escalation in trade tensions. An increase 
in tariffs or trade restrictions (and threats thereof) could lead to a significant reduction in international 
trade, which could have a negative impact on China&#x2019;s export industry, Chinese issuers, the liquidity 
or price of the Portfolio&#x2019;s direct or indirect investments in China and, therefore, the Portfolio.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The 
economy of China differs, often unfavorably, from the US economy in such respects as structure, general 
development, government involvement, wealth distribution, rate of inflation, growth rate, interest rates, 
allocation of resources and capital reinvestment, among others. The Chinese central government has historically 
exercised&#160;substantial control over virtually every sector of the Chinese&#160;economy through administrative 
regulation and/or state ownership or other involvement and actions of the Chinese central and local government 
authorities continue to have a substantial effect on economic conditions in China. In addition, the Chinese 
government has from time to time actively intervened in Chinese companies&#x2019; operations and structures 
and taken actions that influence the prices at which certain goods may be sold, encourage companies to 
invest or concentrate in particular industries, induce mergers between companies in certain industries 
and induce private companies to publicly offer their securities to increase or continue the rate of economic 
growth, control the rate of inflation or otherwise regulate economic expansion. The Chinese government 
may do so in the future as well, potentially having a significant adverse effect on economic conditions 
in China. Moreover, strained relations, border disputes or other conflict between China and neighboring 
countries could adversely affect the Chinese economy.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may obtain exposure to companies 
based or operated in China by investing through legal structures known as variable interest entities 
(&#x201c;VIEs&#x201d;). Instead of directly owning the equity securities of a Chinese company, a VIE enters 
into service and other contracts with the Chinese company. Although the VIE has no equity ownership of 
the Chinese company, the contractual arrangements permit the VIE to consolidate the Chinese company into 
its financial statements. VIE investments are subject to the risk that any breach of these contractual 
arrangements will be subject to Chinese law and jurisdiction, that Chinese law may be interpreted or 
change in a way that affects the enforceability of the VIE&#x2019;s arrangements, or that contracts between 
the Chinese company and the VIE may otherwise not be enforceable under Chinese law. VIE structures also 
could face delisting or other ramifications for failure to meet the requirements of the Securities and 
Exchange Commission, the Public Company Accounting Oversight Board or other United States regulators. 
If any of these or similar risks or developments materialize, the value of investments in VIEs could 
be adversely affected and the Portfolios could incur significant losses with no recourse available. A 
decline or worsening in diplomatic or other relations between the US and China could increase the risks 
associated with the VIE structure.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may invest in eligible renminbi-denominated 
class A shares of equity securities that are listed and traded on certain Chinese stock exchanges (&#x201c;China 
A-Shares&#x201d;) through Hong Kong Stock Connect Program (&#x201c;Stock Connect&#x201d;). While Stock Connect 
is not subject to individual investment quotas, daily and aggregate investment quotas apply to all Stock 
Connect participants, which may restrict or preclude the Portfolio&#x2019;s ability to invest in China 
A-Shares (although the Portfolio would be permitted to sell China A-Shares regardless of the quota balance). 
Stock Connect is also subject to trading, clearance, settlement and operational risks. &lt;/p&gt;</rr:RiskTextBlock>

Portfolio seeks to achieve its investment objective over a full market cycle through a hedged strategy 
investing primarily in convertible fixed income and preferred securities (including those rated below 
investment grade (&#x201c;junk&#x201d;)). The strategy utilizes a relative value approach, focusing on 
convertible securities that are considered to have low volatility. It is expected that the Portfolio 
will invest primarily in small and mid cap companies. The Portfolio also will utilize selective strategy 
level and position level hedges, primarily through short selling and derivatives, seeking to minimize 
macro risk (equity and credit) and interest rate risk. The Portfolio may invest in convertible debt and 
preferred securities of any maturity and any quality. Convertible securities held in the Portfolio generally 
are expected to have maturities between three and seven years at the time of investment, or between five 
and seven years if invested at issuance. Preferred securities generally are of perpetual maturities, 
callable at various points determined by the issuer. The Portfolio management team utilizes bottom up 
fundamental credit, equity and quantitative analysis in conjunction with top down macroeconomic analysis 
to identify individual securities believed to offer compelling value versus comparable risk return.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The 
Portfolio will generally have short positions through selling securities &#x201c;short&#x201d; and through 
investments in derivative instruments, principally swap agreements on individual securities, and may 
use short positions to seek to increase returns or to reduce risk. A short sale involves the sale of 
a security that the Portfolio does not own in the expectation of purchasing the same security (or a security 
exchangeable therefor) at a later date and at a lower price and profiting from the price decline. Similarly, 
when taking short positions with respect to securities through investments in derivative instruments, 
the Investment Manager is expecting the value of such securities to fall during the period of the Portfolio&#x2019;s 
investment exposure.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Although the Portfolio&#x2019;s investment focus is US companies, the Portfolio 
also may invest in non-US companies, including depositary receipts and shares. At certain times, based 
on the currently existing market environment, the Investment Manager may not believe it is able to find 
sufficient opportunities to invest in convertible fixed income and preferred securities and/or take short 
positions and may determine to tactically shift the Portfolio to invest substantially in money market 
instruments, such as short-term US Treasury securities and certificates of deposit.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may 
invest in exchange-traded open-end management investment companies (&#x201c;ETFs&#x201d;), generally those 
that pursue a passive index-based strategy.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;In addition, the Portfolio may, but is not required to (1) 
enter into futures and forward currency contracts and equity, interest rate, credit default and currency 
swap agreements; and (2) write put and call options on securities (including shares of ETFs), indexes 
and currencies, in each case for hedging purposes or to seek to increase returns.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;It is expected that 
the Portfolio will buy and sell securities, and take short positions in securities, frequently in connection 
with implementing its investment strategy.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The 
Portfolio is classified as &#x201c;non-diversified&#x201d; under the Investment Company Act of 1940, as 
amended (the &#x201c;1940 Act&#x201d;), which means that it may invest a relatively high percentage of 
its assets in a limited number of issuers, when compared to a diversified fund.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Securities Risk:&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; The market value of convertible securities may perform like that of non-convertible

that the issuer will not make interest or principal payments, or will not make payments on a timely basis.

security also is subject to the same types of market and issuer risks that apply to the underlying common

decline due to general market conditions that are not specifically related to a particular company, such 
as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes 
in interest or currency rates or adverse investor sentiment generally. The debt securities market can 
be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably 
in response to overall economic conditions or credit tightening.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Prices of bonds and 
other debt securities tend to move inversely with changes in interest rates. Interest rate risk is usually 
greater for fixed-income securities with longer maturities or durations.  A rise in interest rates (or 
the expectation of a rise in interest rates) may result in periods of volatility, decreased liquidity 
and increased &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;redemptions, 
and, as a result, the Portfolio may have to liquidate portfolio securities at disadvantageous prices. 
The Portfolio may be subject to heightened interest rate risk because the Federal Reserve has raised, 
and may continue to raise, interest rates. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio&#x2019;s investments in lower-rated, higher-yielding 
securities (&#x201c;junk bonds&#x201d;) are subject to greater credit risk than its higher rated investments. 
Credit risk is the risk that the issuer will not make interest or principal payments, or will not make 
payments on a timely basis. Non-investment grade securities tend to be more volatile, less liquid and 
are considered speculative. If there is a decline, or perceived decline, in the credit quality of a debt 
security (or any guarantor of payment on such security), the security&#x2019;s value could fall, potentially 
lowering the Portfolio&#x2019;s share price. The prices of non-investment grade securities, unlike investment 
grade debt securities, may fluctuate unpredictably and not necessarily inversely with changes in interest 
rates. The market for these securities may be less liquid and therefore these securities may be harder 
to value or sell at an acceptable price, especially during times of market volatility or decline.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Some 
debt securities may give the issuer the option to call, or redeem, the securities before their maturity, 
and, during a time of declining interest rates, the Portfolio may have to reinvest the proceeds of called 
or redeemed securities in an investment offering a lower yield (and the Portfolio may not fully benefit 
from any increase in the value of its portfolio holdings as a result of declining interest rates).&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Adjustable 
rate securities provide the Portfolio with a certain degree of protection against rises in interest rates, 
although adjustable rate securities will participate in any declines in interest rates. Certain adjustable 
rate securities, such as those with interest rates that fluctuate directly or indirectly based on multiples 
of a stated index, are designed to be highly sensitive to changes in interest rates and can subject the 
holders thereof to extreme reductions of yield and possibly loss of principal. Certain fixed-income securities 
may be issued at a discount from their face value (such as zero coupon securities) or purchased at a 
price less than their stated face amount or at a price less than their issue price plus the portion of 
&#x201c;original issue discount&#x201d; previously accrued thereon, &lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;i.e.&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, 
purchased at a &#x201c;market discount.&#x201d; The amount of original issue discount and/or market discount 
on certain obligations may be significant, and accretion of market discount together with original issue 
discount will cause the Portfolio to realize income prior to the receipt of cash payments with respect 
to these securities.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

more risk than long positions because the maximum sustainable loss on a security purchased is limited 
to the amount paid for the security plus the transaction costs. However, the Portfolio&#x2019;s potential 
loss on a short position is unlimited because, theoretically, there is no limit to the potential price 
increase of a security.  In addition, the Portfolio&#x2019;s short sales transactions are dependent on 
counterparties to its securities borrowing transactions and are subject to the risk of default by a counterparty, 
which could result in a loss of Portfolio assets used as collateral or the loss of monies owed to the

seeking to protect Portfolio investments), may increase volatility, reduce returns, limit gains or magnify 
losses, perhaps substantially, particularly since most derivatives have a leverage component that provides 
investment exposure in excess of the amount invested. Swap agreements; forward currency contracts; over-the-counter 
options on securities (including options on shares of ETFs), indexes and currencies; and other over-the-counter 
derivatives transactions are subject to the risks of the creditworthiness of and default by the counterparty 
and consequently may lose all or a portion of their value due solely to the creditworthiness of or default 
by the counterparty.  Over-the-counter derivatives frequently may be illiquid and difficult to value. 
Changes in liquidity may result in significant, rapid and unpredictable changes in the prices for derivatives. 
These derivatives transactions, as well as the exchange-traded futures and options in which the Portfolio 
may invest, are subject to many of the risks of, and can be highly sensitive to changes in the value 
of the related reference asset, index or rate. As such, a small investment could have a potentially large 
impact on the Portfolio&#x2019;s performance. In fact, many derivatives may be subject to greater risks 
than those associated with investing directly in the underlying or other reference asset. Derivatives 
transactions incur costs, either explicitly or implicitly, which reduce returns, and costs of engaging 
in such transactions may outweigh any gains or any losses averted from hedging activities. Successful 
use of derivatives, whether for hedging or for other investment purposes, is subject to the Investment 
Manager&#x2019;s ability to predict correctly movements in the direction of the relevant reference asset 
or market and, for hedging activities, correlation of the derivative instruments used with the investments 
seeking to be hedged. Use of derivatives transactions, even if entered into for hedging purposes, may 
cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. 
When the Portfolio enters into derivatives transactions, it may be required to post margin and make settlement 
payments while the positions are open, and the Portfolio may have to sell a security at a disadvantageous 
time or price to meet such obligations. Derivatives transactions are also subject to operational and 
legal risk.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

tax-deferred arrangements such as 401(k) plans or individual retirement accounts. Returns shown below 
for the Portfolio&#x2019;s R6 Shares (which were not operational as of December 31, 2024) reflect the 
performance of the Portfolio&#x2019;s Institutional Shares. R6 Shares would have had substantially similar

securities, principally common stocks, of US and non-US companies, including those in emerging markets. 
The Portfolio normally invests in equity securities listed on a national or other recognized securities 
exchange of companies that the Investment Manager considers to have an &#x201c;economic franchise,&#x201d; 
meaning companies that have historically shown an ability to generate unleveraged returns, at or above 
their cost of capital, for long periods of time. The Investment Manager considers that strong business 
franchises are often able to accomplish this performance and status because of competitive advantages 
such as an established or recognized brand, proprietary intellectual property or other intangible assets 
or industry economics such as relatively high customer switching costs. Under normal circumstances, the 
Portfolio invests at least 80% of its assets in equity securities. The Portfolio may invest in the equity 
securities of any size company.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Investment Manager may seek to hedge some or all foreign

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets 
are increasingly interconnected, and conditions and events in one country, region or financial market 
may adversely impact issuers worldwide. As a result, local, regional or global events such as war or 
military conflict, acts of terrorism, the spread of infectious illness or other public health issues, 
social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply 
chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of 
sanctions or other similar measures, recessions or other events could have a significant negative impact 
on global economic and market conditions. For example, a public health or other emergency and aggressive 
responses taken by many governments or voluntarily imposed by private parties, including closing borders, 
restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure 
of, or operational changes to, many retail and other businesses, may have severe negative impacts on 
markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless. In addition, investments denominated in currencies other than US dollars may experience 
a decline in value, in US dollar terms, due solely to fluctuations in currency exchange rates. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

of countries with emerging markets may be based predominantly on only a few industries, may be highly 
vulnerable to changes in local or global trade conditions, and may suffer from extreme debt burdens or 
volatile inflation rates. Further, investments in securities of issuers located in certain emerging countries 
involve the risk of loss resulting from problems in share registration, settlement or custody, substantial 
economic, political and social disruptions and the imposition of sanctions or exchange controls (including 
repatriation restrictions). The securities markets of emerging market countries have historically been 
extremely volatile and less liquid than more developed markets. These market conditions may continue 
or worsen. Investments in these countries may be subject to political, economic, legal, market and currency 
risks. Significant devaluation of emerging market currencies against the US dollar may occur subsequent 
to acquisition of investments denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may increase volatility, reduce returns, limit gains or magnify losses, perhaps substantially, particularly 
since forward currency contracts, like most derivative instruments, have a leverage component that provides 
investment exposure in excess of the amount invested. Forward currency contracts are subject to the risks 
of the creditworthiness of and default by the counterparty and consequently may lose all or a portion 
of their value due solely to the creditworthiness of or default by the counterparty. Forward currency 
contracts also may be illiquid. Changes in liquidity may result in significant, rapid and unpredictable 
changes in the value of such contracts. Forward currency contracts are subject to many of the risks of, 
and can be highly sensitive to changes in the value of, the related currencies. As such, a small investment 
could have a potentially large impact on the Portfolio&#x2019;s performance. Forward currency contracts 
incur costs, which reduce returns, and costs of engaging in such transactions may outweigh any gains 
or any losses averted from hedging activities. Successful use of forward currency contracts, whether 
for hedging or for other investment purposes, is subject to the Investment Manager&#x2019;s ability to 
accurately predict movements in currency exchange rates and, for hedging transactions, there may be imperfect 
correlations between movements in &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;exchange 
rates that could cause the Portfolio to incur significant losses. Use of forward currency contracts, 
even if entered into for hedging purposes, may cause the Portfolio to experience losses greater than 
if the Portfolio had not engaged in such transactions.&lt;/p&gt;</rr:RiskTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;differing

sanctions or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/p&gt;</rr:RiskTextBlock>

countries generally have economic structures that are less diverse and mature, and political systems 
that are less stable, than those of developed countries. The economies of countries with emerging markets 
may be based predominantly on only a few industries, may be highly vulnerable to changes in local or 
global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to political, economic, legal, market and currency risks. Significant devaluation 
of emerging market currencies against the US dollar may occur subsequent to acquisition of investments 
denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Portfolio invests primarily in equity securities, principally common stocks, of infrastructure companies 
and concentrates its investments in industries represented by infrastructure companies. Lazard Asset 
Management LLC (the &#x201c;Investment Manager&#x201d;) focuses on companies with a minimum market capitalization 
of $250 million that own physical infrastructure and which the Investment Manager believes are undervalued.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Under 
normal circumstances, the Portfolio invests at least 80% of its assets in equity securities of infrastructure 
companies, which consist of utilities, pipelines, toll roads, airports, railroads, ports, telecommunications 
and other infrastructure companies, with securities listed on a national or other recognized securities 
exchange.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Under normal market conditions, the Portfolio invests significantly (at least 
40%&#x2014;unless market conditions are not deemed favorable by the Investment Manager, in which case 
the Portfolio would invest at least 30%) in infrastructure companies organized or located outside the 
US or doing a substantial amount of business outside the US. The Investment Manager allocates the Portfolio&#x2019;s 
assets among various regions and countries, including the United States (but in no less than three different 
countries). The Portfolio may invest in equity securities of companies with some business activities 
located in emerging market countries.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Investment Manager generally seeks to substantially hedge 
foreign currency exposure in the Portfolio against movements relative to the US dollar by entering into 
foreign currency forward contracts, although the Portfolio&#x2019;s total foreign currency exposure may 
not be fully hedged at all times.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;As part of its investment strategy, the Portfolio may use

the Portfolio is classified as &#x201c;diversified&#x201d; under the Investment Company Act of 1940, as

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

of repurchase agreements or purchase and sale contracts. Under a repurchase agreement, the seller agrees 
to repurchase a security (typically a security issued or guaranteed by the U.S. Government) at a mutually 
agreed upon time and price. This insulates the Portfolio from changes in the market value of the security 
during the period. A purchase and sale contract is similar to a repurchase agreement, but purchase and 
sale contracts provide that the purchaser receives any interest on the security paid during the period. 
If the seller fails to repurchase the security in either situation and the market value declines, the 
Portfolio may lose money.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries

and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Emerging market countries generally have economic structures that are less diverse and mature, and political 
systems that are less stable, than those of developed countries. The economies of countries with emerging 
markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local 
or global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to political, economic, legal, market and currency risks. Significant devaluation 
of emerging market currencies against the US dollar may occur subsequent to acquisition of investments 
denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Portfolio investments), may increase volatility, reduce returns, limit gains or magnify losses, perhaps 
substantially, particularly since forward currency contracts, like most derivative instruments, have 
a leverage component that provides investment exposure in excess of the amount invested. Forward currency 
contracts are subject to the risks of the creditworthiness of and default by the counterparty and consequently 
may lose all or a portion of their value due solely to the creditworthiness of or default by the counterparty. 
Forward currency contracts also may be illiquid. Changes in liquidity may result in significant, rapid 
and unpredictable changes in the value of such contracts. Forward currency contracts are subject to many 
of the risks of, and can be highly sensitive to changes in the value of, the related currencies. As such, 
a small investment could have a potentially large impact on the Portfolio&#x2019;s performance. Forward 
currency contracts incur costs, which reduce returns, and costs of engaging in such transactions may 
outweigh any gains or any losses averted from hedging activities. Successful use of forward currency 
contracts, whether for hedging or for other investment purposes, is subject to the Investment Manager&#x2019;s 
ability to accurately predict movements in currency exchange rates and, for hedging transactions, there 
may be imperfect correlations between movements in exchange rates that could cause the Portfolio to incur 
significant losses. Use of forward currency contracts, even if entered into for hedging purposes, may 
cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

After-tax returns of the Portfolio&#x2019;s other share classes will vary. After-tax returns are calculated 
using the historical highest individual marginal income tax rates and do not reflect the impact of state

from those shown. The after-tax returns shown are not relevant to investors who hold their shares through 
tax-deferred arrangements such as 401(k) plans or individual retirement accounts. Returns shown below 
for the Portfolio&#x2019;s R6 Shares (which were not operational as of December 31, 2024) reflect the 
performance of the Portfolio&#x2019;s Institutional Shares. R6 Shares would have had substantially similar 
returns as Institutional Shares because the share classes are invested in the same portfolio of securities,

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets 
are increasingly interconnected, and conditions and events in one country, region or financial market 
may adversely impact issuers worldwide. As a result, local, regional or global events such as war or 
military conflict, acts of terrorism, the spread of infectious illness or other public health issues, 
social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply 
chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of 
sanctions or other similar measures, recessions or other events could have a significant negative impact 
on global economic and market conditions. For example, a public health or other emergency and aggressive 
responses taken by many governments or voluntarily imposed by private parties, including closing borders, 
restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure 
of, or operational changes to, many retail and other businesses, may have severe negative impacts on 
markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

of countries with emerging markets may be based predominantly on only a few industries, may be highly 
vulnerable to changes in local or global trade conditions, and may suffer from extreme debt burdens or 
volatile inflation rates. Further, investments in securities of issuers located in certain emerging countries 
involve the risk of loss resulting from problems in share registration, settlement or custody, substantial 
economic, political and social disruptions and the imposition of sanctions or exchange controls (including 
repatriation restrictions). The securities markets of emerging market countries have historically been 
extremely volatile and less liquid than more developed markets. These market conditions may continue 
or worsen. Investments in these countries may be subject to political, economic, legal, market and currency 
risks. Significant devaluation of emerging market currencies against the US dollar may occur subsequent

of US and non-US companies, including those in emerging markets. In managing the Portfolio,&#160;the 
Investment Manager&#160;utilizes a quantitatively driven, bottom up stock selection process. The Portfolio 
management team selects investments for the Portfolio from a broad investment universe of non-US stocks 
and depositary receipts, including American Depositary Receipts (&#x201c;ADRs&#x201d;), Global Depositary 
Receipts and European Depositary Receipts, real estate investment trusts (&#x201c;REITs&#x201d;), warrants 
and rights. The active, quantitative approach utilized by the Portfolio management team involves initial 
screening, risk assessment and evaluation of each company relative to its global peers. The Portfolio 
will typically invest the majority of its assets in securities of non-US developed market companies, 
using an objective, systematic investment process that blends both risk and stock ranking assessments 
designed to capture attractive risk-to-return characteristics. In addition to a multidimensional assessment 
of risk, each company is evaluated daily according to four independent measures: growth, value, sentiment 
and quality. The Portfolio may invest across the capitalization spectrum.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Under normal circumstances,

assets among countries and regions will vary from time to time based on the Investment Manager&#x2019;s 
judgment and its analysis of market conditions. Implementation of the Portfolio&#x2019;s investment strategy 
may, during certain periods, result in the investment of a significant portion of the Portfolio&#x2019;s 
assets in a particular country.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may invest in exchange-traded open-end management

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments,

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic structures that are less diverse and mature, and political systems that are less stable, than 
those of developed countries. The economies of countries with emerging markets may be based predominantly 
on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and 
may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities 
of issuers located in certain emerging countries involve the risk of loss resulting from problems in 
share registration, settlement or custody, substantial economic, political and social disruptions and 
the imposition of sanctions or exchange controls (including repatriation restrictions). The securities 
markets of emerging market countries have historically been extremely volatile and less liquid than more 
developed markets. These market conditions may continue or worsen. Investments in these countries may 
be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging 
market currencies against the US dollar may occur subsequent to acquisition of investments denominated 
in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

process. The Investment Manager&#x2019;s ability to monitor and, if necessary, adjust its quantitative 
model could be adversely affected by various factors including incorrect or outdated market and other 
data inputs. Factors that affect a security&#x2019;s value can change over time, and these changes may 
not be reflected in the quantitative model. In addition, factors used in quantitative analysis and the

realty-related company. Consequently, investments in REITs could lead to investment results that may 
be significantly different from investments in the broader securities markets. The risks related to investments 
in realty-related companies include, but are not limited to: adverse changes in general economic and 
local market conditions; adverse developments in employment; changes in supply or demand for similar 
or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest 
rates; operating or development expenses; and lack of available financing. Due to certain special considerations 
that apply to REITs, investments in REITs may carry additional risks not necessarily present in investments 
in other securities. REIT securities (including those trading on national exchanges) typically have trading 
volumes that are less than those of securities of other types of companies, which may affect the Portfolio&#x2019;s 
ability to trade or liquidate those securities. An investment in a REIT may be adversely affected if 
the REIT fails to comply with applicable laws and regulations, including failing to qualify as a REIT 
under the Internal Revenue Code of 1986, as amended. Failure to qualify with any of these requirements 
could jeopardize a company&#x2019;s status as a REIT. The Portfolio generally will have no control over 
the operations and policies of a REIT, including qualification as a REIT.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Shares of ETFs may trade at prices that vary from their net asset values, sometimes significantly. The 
shares of ETFs may trade at prices at, below or above their net asset value. In addition, the performance 
of an ETF pursuing a passive index-based strategy may diverge from the performance of the index. The 
Portfolio&#x2019;s investments in ETFs are subject to the risks of the ETFs&#x2019; investments, as well 
as to the general risks of investing in ETFs. The Portfolio will bear not only the Portfolio&#x2019;s 
management fees and operating expenses, but also the Portfolio&#x2019;s proportional share of the management 
fees and operating expenses of the ETFs in which the Portfolio invests. Although Section 12 of the Investment 
Company Act of 1940, as amended (the &#x201c;1940 Act&#x201d;) limits the amount of the Portfolio&#x2019;s 
assets that may be invested in one or more ETFs, Rule 12d1-4 under the 1940 Act allows the Portfolio 
to acquire the securities of another investment company, including ETFs, in excess of the limitations 
imposed by Section 12 of the 1940 Act, subject to certain limitations and conditions. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

those of developed countries. The economies of countries with emerging markets may be based predominantly 
on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and 
may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities 
of issuers located in certain emerging countries involve the risk of loss resulting from problems in 
share registration, settlement or custody, substantial economic, political and social disruptions and 
the imposition of sanctions or exchange controls (including repatriation restrictions). The securities 
markets of emerging market countries have historically been extremely volatile and less liquid than more 
developed markets. These market conditions may continue or worsen. Investments in these countries may 
be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging 
market currencies against the US dollar may occur subsequent to acquisition of investments denominated

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and 
may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities 
of issuers located in certain emerging countries involve the risk of loss resulting from problems in 
share registration, settlement or custody, substantial economic, political and social disruptions and 
the imposition of sanctions or exchange controls (including repatriation restrictions). The securities 
markets of emerging market countries have historically been extremely volatile and less liquid than more 
developed markets. These market conditions may continue or worsen. Investments in these countries may 
be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging 
market currencies against the US dollar may occur subsequent to acquisition of investments denominated

Small and mid cap companies carry additional risks because their earnings tend to be less predictable, 
their share prices more volatile and their securities less liquid than larger, more established companies. 
The shares of small and mid cap companies tend to trade less frequently than those of larger companies, 
which can have an adverse effect on the pricing of these securities and on the ability to sell these 
securities when the Investment Manager deems it appropriate.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

a lack of company information, &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;differing

sanctions or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/p&gt;</rr:RiskTextBlock>

periods, result in the investment of a significant portion of the Portfolio&#x2019;s assets in a particular 
country, such as Japan, and the Portfolio would be expected to be affected by political, regulatory, 
market, economic and social developments affecting that country.  Over the last few decades, Japan&#x2019;s 
economic growth rate had remained relatively low compared to that of its Asian neighbors and other major 
developed economies mainly due to deflation.  Japan has few natural resources and limited land area and 
is reliant on imports for its commodity needs.  Fluctuations or shortages in relevant commodity markets 
could have a negative impact on Japan&#x2019;s economy.  In addition, Japan is subject to the risk of 
natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, which could negatively 
affect the Portfolio. The Japanese economy also can be adversely affected by trade tariffs, other protectionist 
measures, competition from emerging economies, and the economic conditions of its trading partners.  
Japan has a growing economic relationship with China and other Southeast Asian countries, and economic, 
political or social instability in those countries could have an adverse effect on Japan&#x2019;s economy. 
 The Japanese yen has fluctuated widely at times, and any increase in the yen&#x2019;s value may cause 
a decline in Japan&#x2019;s exports. &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;economic

confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/p&gt;</rr:RiskTextBlock>

countries generally have economic structures that are less diverse and mature, and political systems 
that are less stable, than those of developed countries. The economies of countries with emerging markets 
may be based predominantly on only a few industries, may be highly vulnerable to changes in local or 
global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to political, economic, legal, market and currency risks. Significant devaluation 
of emerging market currencies against the US dollar may occur subsequent to acquisition of investments 
denominated in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

actively managed closed-end management investment companies (&#x201c;closed-end funds&#x201d;, and, together 
with ETFs, &#x201c;Underlying Funds&#x201d;). ETFs in which the Portfolio may invest include both ETFs 
designed to correlate directly with an index and ETFs designed to correlate inversely with an index and 
may include actively-managed ETFs. The Portfolio, through Underlying Funds in which it invests, may invest 
in non-US companies (including those in emerging markets), and the Portfolio also may invest directly 
in equity and debt securities in addition to its investments in Underlying Funds. The Portfolio&#x2019;s 
investment portfolio is concentrated in a relatively small number of holdings (generally 10 to 30). &lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;Investors

of a security that the Portfolio does not own in the expectation of purchasing the same security (or 
a security exchangeable therefor) at a later date and at a lower price and profiting from the price decline. 
Similarly, when taking short positions with respect to securities through investments in derivative instruments,

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets 
are increasingly interconnected, and conditions and events in one country, region or financial market 
may adversely impact issuers worldwide. As a result, local, regional or global events such as war or 
military conflict, acts of terrorism, the spread of infectious illness or other public health issues, 
social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply 
chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of 
sanctions or other similar measures, recessions or other events could have a significant negative impact 
on global economic and market conditions. For example, a public health or other emergency and aggressive 
responses taken by many governments or voluntarily imposed by private parties, including closing borders, 
restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure 
of, or operational changes to, &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;many 
retail and other businesses, may have severe negative impacts on markets worldwide. Additionally, general 
market conditions may affect the value of a Portfolio&#x2019;s securities, including changes in interest 
rates, currency rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, 
currency restrictions or similar actions (or retaliatory measures taken in response to such actions), 
or the threat or potential of one or more such events and developments, could lead to price volatility 
and overall declines in the US and global investment markets.&lt;/p&gt;</rr:RiskTextBlock>

funds and ETFs may trade at prices at, below or above their net asset value. Shares of closed-end funds, 
in particular, frequently trade at persistent discounts to their net asset value. In addition, the performance

proportional share of the management fees and operating expenses of the Underlying Funds in which the 
Portfolio invests. Rule 12d1-4 under the 1940 Act allows the Portfolio to acquire the securities of another 
investment company, including an Underlying Fund, in excess of the limitations imposed by Section 12

Short positions may involve substantial risks. If a short position appreciates in value during the period 
of the Portfolio&#x2019;s investment, there will be a loss to the Portfolio that could be substantial. 
Short positions involve more risk than long positions because the maximum sustainable loss on a security 
purchased is limited to the amount paid for the security plus the transaction costs. However, the Portfolio&#x2019;s 
potential loss on a short position is unlimited because, theoretically, there is no limit to the potential 
price increase of a security.  In addition, the Portfolio&#x2019;s short sales transactions are dependent 
on counterparties to its securities borrowing transactions and are subject to the risk of default by 
a counterparty, which could result in a loss of Portfolio assets used as collateral or the loss of monies 
owed to the Portfolio by a counterparty.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries

or less efficient trading markets, political instability, a lack of company information, differing auditing 
and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Emerging market countries generally have economic structures that are less diverse and mature, and political 
systems that are less stable, than those of developed countries. The economies of countries with emerging 
markets may be based predominantly on only a few industries, may be highly vulnerable to changes in local 
or global trade conditions, and may suffer from extreme debt burdens or volatile inflation rates. Further, 
investments in securities of issuers located in certain emerging countries involve the risk of loss resulting 
from problems in share registration, settlement or custody, substantial economic, political and social 
disruptions and the imposition of sanctions or exchange controls (including repatriation restrictions). 
The securities markets of emerging market countries have historically been extremely volatile and less 
liquid than more developed markets. These market conditions may continue or worsen. Investments in these 
countries may be subject to &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;political, 
economic, legal, market and currency risks. Significant devaluation of emerging market currencies against

Debt Securities Risk:&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; The market value of a debt security may decline due to general 
market conditions that are not specifically related to a particular company, such as real or perceived 
adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency 
rates or adverse investor sentiment generally. The debt securities market can be susceptible to increases 
in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall 
economic conditions or credit tightening.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Prices of bonds and other debt securities 
tend to move inversely with changes in interest rates. Interest rate risk is usually greater for fixed-income 
securities with longer maturities or durations.  A rise in interest rates (or the expectation of a rise 
in interest rates) may result in periods of volatility, decreased liquidity and increased redemptions, 
and, as a result, the Portfolio may have to liquidate portfolio securities at disadvantageous prices. 
The Portfolio may be subject to heightened interest rate risk because the Federal Reserve has raised, 
and may continue to raise, interest rates. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio&#x2019;s investments in lower-rated, higher-yielding 
securities (&#x201c;junk bonds&#x201d;) are subject to greater credit risk than its higher rated investments. 
Credit risk is the risk that the issuer will not make interest or principal payments, or will not make 
payments on a timely basis. Non-investment grade securities tend to be more volatile, less liquid and 
are considered speculative. If there is a decline, or perceived decline, in the credit quality of a debt 
security (or any guarantor of payment on such security), the security&#x2019;s value could fall, potentially 
lowering the Portfolio&#x2019;s share price. The prices of non-investment grade securities, unlike investment 
grade debt securities, may fluctuate unpredictably and not necessarily inversely with changes in interest 
rates. The market for these securities may be less liquid and therefore these securities may be harder 
to value or sell at an acceptable price, especially during times of market volatility or decline.&lt;/p&gt;</rr:RiskTextBlock>

volatility, reduce returns, limit gains or magnify losses, perhaps substantially, particularly since 
most derivatives have a leverage component that provides investment exposure in excess of the amount 
invested. Swap agreements; forward currency contracts; over-the-counter options on securities (including 
options on shares of ETFs), indexes and currencies; and other over-the-counter derivatives transactions 
are subject to the risks of the creditworthiness of and default by the counterparty and consequently 
may lose all or a portion of their value due solely to the creditworthiness of or default by the counterparty. 
 Over-the-counter derivatives frequently may be illiquid and difficult to value. Changes in liquidity 
may result in significant, rapid and unpredictable changes in the prices for derivatives. These derivatives 
transactions, as well as the exchange-traded futures and options in which the Portfolio may invest, are 
&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;subject 
to many of the risks of, and can be highly sensitive to changes in the value of the related reference 
asset, index or rate. As such, a small investment could have a potentially large impact on the Portfolio&#x2019;s 
performance. In fact, many derivatives may be subject to greater risks than those associated with investing 
directly in the underlying or other reference asset. Derivatives transactions incur costs, either explicitly 
or implicitly, which reduce returns, and costs of engaging in such transactions may outweigh any gains 
or any losses averted from hedging activities. Successful use of derivatives, whether for hedging or 
for other investment purposes, is subject to the Investment Manager&#x2019;s ability to predict correctly 
movements in the direction of the relevant reference asset or market and, for hedging activities, correlation 
of the derivative instruments used with the investments seeking to be hedged. Use of derivatives transactions, 
even if entered into for hedging purposes, may cause the Portfolio to experience losses greater than 
if the Portfolio had not engaged in such transactions. When the Portfolio enters into derivatives transactions, 
it may be required to post margin and make settlement payments while the positions are open, and the 
Portfolio may have to sell a security at a disadvantageous time or price to meet such obligations. Derivatives 
transactions are also subject to operational and legal risk.&lt;/p&gt;</rr:RiskTextBlock>

Exposure to the commodities markets may subject the Portfolio to greater volatility than other types 
of investments. The values of commodities and commodity-linked derivative instruments are affected by 
events that may have less impact on the values of equity and fixed income securities. Investments linked 
to the prices of commodities are considered speculative. Because the value of a commodity-linked derivative 
instrument, such as a futures contract on a physical commodity, typically is based upon the price movements 
of the underlying reference asset, index or rate, the value of these instruments will rise or fall in 
response to changes in the underlying reference asset, index or rate. Prices of commodities and commodity-linked 
investments may fluctuate significantly over short periods for a variety of factors, including: changes 
in supply and demand relationships; weather; agricultural or livestock markets; agricultural or livestock 
disease or pestilence; trade relationships; fiscal, monetary and exchange control programs; and embargoes, 
tariffs, terrorism and international economic, political, military and regulatory developments.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

by developments in that sector.  Information technology companies generally operate in intensely competitive 
markets on a worldwide basis.  Also, because technological development in many areas increases at a rapid 
rate, these companies often produce products with very short life cycles and face the risk of product 
obsolescence.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

shares of ETFs), indexes and currencies; and (3) invest in structured notes, in each case for hedging

Risk:&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; The Portfolio may incur losses due to declines in one or more markets in which 
it invests. These declines may be the result of, among other things, political, regulatory, market, economic 
or social developments affecting the relevant market(s). To the extent that such developments impact 
specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s investments 
in such industries, market sectors, countries and/or geographic regions can be expected to be particularly 
affected, especially if such investments are a significant portion of its investment portfolio. In addition, 
turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may 
negatively affect many issuers, which could adversely affect the Portfolio. Global economies and financial 
markets are increasingly interconnected, and conditions and events in one country, region or financial 
market may adversely impact issuers worldwide. As a result, local, regional or global events such as 
war or military conflict, acts of terrorism, the spread of infectious illness or other public health 
issues, social unrest, natural disasters, extreme weather, other geological events, man-made disasters, 
supply chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition 
of sanctions or other similar measures, recessions or other events could have a significant negative 
impact on global economic and market conditions. For example, a public health or other emergency and 
aggressive responses taken by many governments or voluntarily imposed by private parties, including closing 
borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the 
closure of, or operational changes to, many retail and other businesses, may have severe negative impacts 
on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Resources Risk:&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; Investments related to natural resources may be affected by numerous factors, 
including events occurring in nature, inflationary pressures and domestic and international politics. 
For example, events occurring in nature (such as earthquakes or fires in prime natural resource areas) 
and political events (such as coups or military confrontations) can affect the overall supply of a natural 
resource and the value of companies involved in such natural resource. Political risks and other risks 
to which non-US companies are subject also may affect US companies if they have significant operations 
or investments in non-US countries. In addition, interest rates, prices of raw materials and other commodities, 
international economic developments, energy conservation, tax and other government regulations (both 
US and non-US) may affect the supply of and demand for natural resources, which can affect the profitability 
and value of securities issued by companies in the natural resources category. Securities of companies 
within specific natural resources sub-categories can perform differently than the overall market. This 
may be due to changes in such things as the regulatory or competitive environment or to changes in investor 
perceptions.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Estate Investments, including REITs, could lose money due to the performance of real estate-related securities 
even if securities markets generally are experiencing positive results. The performance of Real Estate 
Investments may be determined to a great extent by the current status of the real estate industry in 
general, or by other factors that may affect the real estate industry, &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;even 
if other industries would not be so affected. Consequently, Real Estate Investments could lead to investment 
results that may be significantly different from investments in other real assets categories or investments 
in the broader securities markets. The risks related to investments in Real Estate Investments include, 
but are not limited to: adverse changes in general economic and local market conditions; adverse developments 
in employment; changes in supply or demand for similar or competing properties; unfavorable changes in 
applicable taxes, governmental regulations and interest rates; operating or development expenses; and 
lack of available financing.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Due to certain special considerations that apply to REITs, 
investments in REITs may carry additional risks not necessarily present in investments in other securities. 
REIT securities (including those trading on national exchanges) typically have trading volumes that are 
less than those of securities of other types of companies, which may affect the Portfolio&#x2019;s ability 
to trade or liquidate those securities. An investment in a REIT may be adversely affected if the REIT 
fails to comply with applicable laws and regulations, including failing to qualify as a REIT under the 
Internal Revenue Code of 1986, as amended. Failure to qualify with any of these requirements could jeopardize 
a company&#x2019;s status as a REIT. The Portfolio generally will have no control over the operations 
and policies of a REIT, including qualification as a REIT.&lt;/p&gt;</rr:RiskTextBlock>

Securities and instruments of infrastructure companies, which consist of utilities, pipelines, toll roads, 
airports, railroads, ports, telecommunications and other infrastructure companies, are more susceptible 
to adverse economic or regulatory occurrences affecting their industries. Infrastructure companies may 
be subject to a variety of factors that may adversely affect their business or operations, including 
high interest costs in connection with capital construction programs, high leverage, costs associated 
with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased 
competition from other providers of services, uncertainties concerning the availability of fuel at reasonable 
prices, the effects of energy conservation policies and other factors. Infrastructure companies also 
may be affected by or subject to, among other factors, regulation by various government authorities, 
including rate regulation, and service interruption due to environmental, operational or other mishaps.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Investments linked to the prices of commodities are considered speculative. Because the value of a commodity-linked 
derivative instrument, such as a futures contract on a physical commodity, typically is based upon the 
price movements of the underlying reference asset, index or rate, the value of these instruments will 
rise or fall in response to changes in the underlying reference asset, index or rate. Prices of commodities 
and commodity-linked investments may fluctuate significantly over short periods for a variety of factors, 
including: changes in supply and demand relationships; weather; agricultural or livestock markets; agricultural 
or livestock disease or pestilence; trade relationships; fiscal, monetary and exchange control programs; 
and embargoes, tariffs, terrorism and international economic, political, military and regulatory developments.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic conditions or credit tightening.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Prices of bonds and other debt securities 
tend to move inversely with changes in interest rates. Interest rate risk is usually greater for fixed-income 
securities with longer maturities or durations.  A rise in interest rates (or the expectation of a rise 
in interest rates) may result in periods of volatility, decreased liquidity and increased redemptions, 
and, as a result, the Portfolio may have to liquidate portfolio securities at disadvantageous prices. 
The Portfolio may be subject to heightened interest rate risk because the Federal Reserve has raised, 
and may continue to raise, interest rates. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The 
Portfolio&#x2019;s investments in lower-rated, higher-yielding securities (&#x201c;junk bonds&#x201d;) are 
subject to greater credit risk than its higher rated investments. Credit risk is the risk that the issuer 
will not make interest or principal payments, or will not make payments on a timely basis. Non-investment 
grade securities tend to be more volatile, less liquid and are considered speculative. If there is a 
decline, or perceived decline, in the credit quality of a debt security (or any guarantor of payment 
on such security), the security&#x2019;s value could fall, potentially lowering the Portfolio&#x2019;s 
share price. The prices of non-investment grade securities, unlike investment grade debt securities, 
may fluctuate unpredictably and not necessarily inversely with changes in interest rates. The market 
for these securities may be less liquid and therefore these securities may be harder to value or sell 
at an acceptable price, especially during times of market volatility or decline.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Some debt securities 
may give the issuer the option to call, or redeem, the securities before their maturity, and, during 
a time of declining interest rates, the Portfolio may have to reinvest the proceeds of called or redeemed 
securities in an investment offering a lower yield (and the Portfolio may not fully benefit from any 
increase in the value of its portfolio holdings as a result of declining interest rates).&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Structured notes 
are privately negotiated debt instruments where the principal and/or interest is determined by reference 
to a specified asset, market or rate, or the differential performance of two assets or markets. Structured 
notes can have risks of both debt securities and derivatives transactions.&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and 
may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities 
of issuers located in certain emerging countries involve the risk of loss resulting from problems in 
share registration, settlement or custody, substantial economic, political and social disruptions and 
the imposition of sanctions or exchange controls (including repatriation restrictions). The securities 
markets of emerging market countries have historically been extremely volatile and less liquid than more 
developed markets. These market conditions may continue or worsen. Investments in these countries may 
be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging 
market currencies against the US dollar may occur subsequent to acquisition of investments denominated

Portfolio investments), may increase volatility, reduce returns, limit gains or magnify losses, perhaps 
substantially, particularly since most derivatives have a leverage component that provides investment 
exposure in excess of the amount invested. Swap agreements; forward currency contracts; over-the-counter 
options on securities (including options on shares of ETFs), indexes and currencies; structured notes; 
and other over-the-counter derivatives transactions are subject to the risks of the creditworthiness 
of and default by the counterparty and consequently may lose all or a portion of their value due solely 
to the creditworthiness of or default by the counterparty.  Over-the-counter derivatives frequently may 
be illiquid and difficult to value. Changes in liquidity may result in significant, rapid and unpredictable 
changes in the prices for derivatives. These derivatives transactions, as well as the exchange-traded 
futures and options in which the Portfolio may invest, are subject to many of the risks of, and can be 
highly sensitive to changes in the value of the related reference asset, index or rate. As such, a small 
investment could have a potentially large impact on the Portfolio&#x2019;s performance. In fact, many 
derivatives may be subject to greater risks than those associated with investing directly in the underlying 
or other reference asset. Derivatives transactions incur costs, either explicitly or implicitly, which 
reduce returns, and costs of engaging in such transactions may outweigh any gains or any losses averted 
from hedging activities. Successful use of derivatives, whether for hedging or for other investment purposes, 
is subject to the Investment Manager&#x2019;s ability to predict correctly movements in the direction 
of the relevant reference asset or market and, for hedging activities, correlation of the derivative 
instruments used with the investments seeking to be hedged. Use of derivatives transactions, even if 
entered into for hedging purposes, may cause the Portfolio to experience losses greater than if the Portfolio 
had not engaged in such transactions. When the Portfolio enters into derivatives transactions, it may 
be required to post margin and make settlement payments while the positions are open, and the Portfolio 
may have to sell a security at a disadvantageous time or price to meet such obligations. Derivatives 
transactions are also subject to operational and legal risk. The same risks, as applicable, apply to 
derivatives transactions by the Subsidiary.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

the Subsidiary, the Portfolio is exposed to the risks associated with the Subsidiary&#x2019;s investments, 
which generally include the risks of investing in commodity-related derivative instruments (described 
elsewhere in this Prospectus).  Income and gains from commodities or certain commodity-linked derivative

purposes. Without such qualification, the Portfolio could fail to qualify as a RIC and be subject to 
tax. The Portfolio intends to gain exposure indirectly to commodity markets by investing in its Subsidiary, 
which invests primarily in these commodity-linked derivative instruments. The tax treatment of the Portfolio&#x2019;s 
investments in the Subsidiary may be adversely affected by future legislation, Treasury regulations, 
court decisions and/or guidance issued by the Internal Revenue Service that could affect whether income

to factors such as equity market performance, interest rates and credit spreads and its implied volatility, 
in order to assist the Investment Manager in forming a view regarding the relative value of the convertible 
security when assessed against:  (i) comparable convertible securities; (ii) its historical price-to-book 
ratios (a measure of the security&#x2019;s issuer&#x2019;s market capitalization (or valuation) to its 
book value); (iii) the creditworthiness of the issuer; and/or (iv) what the Investment Manager assesses 
to be the future growth outlook or valuation prospects of the equity into which the security is convertible;

outlook for the issuer, and the potential for improving valuations, in the underlying equity securities. 
&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The 
Portfolio may invest without limitation in securities rated below investment grade (i.e., lower than 
Baa by Moody&#x2019;s Investors Service, Inc. (&#x201c;Moody&#x2019;s&#x201d;) or lower than BBB by S&amp;amp;P 
Global Ratings (&#x201c;S&amp;amp;P&#x201d;)) (&#x201c;junk bonds&#x201d;) or equivalent unrated securities as 
determined by the Investment Manager.  Additionally, the Portfolio is not restricted to investments in 
securities of any particular maturity or duration, and there are no restrictions on the Portfolio&#x2019;s 
average maturity or duration.  Duration is an estimate of the sensitivity of the price of a fixed income 
or convertible security to a change in interest rates.  Generally, the longer the duration, the higher 
the expected volatility.  For example, the market price of a fixed income or convertible security with 
a duration of three years would be expected to decline 3% if interest rates rose 1%.  Conversely, the 
market price of the same security would be expected to increase 3% if interest rates fell 1%.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may 
invest up to 20% of its assets in securities and other assets which need not be convertible securities 
as described below and need not be economically tied to the US as described above, including securities 
of emerging markets issuers.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;&#x201c;Convertible securities&#x201d; are fixed-income and 
preferred equity securities that pay a fixed or floating rate of interest or dividends and that convert 
into: (1) underlying shares of common stock or other equity securities of the issuer of the convertible 
securities or of another issuer; (2) cash; or (3) a combination of cash and common stock or other equity 
securities of the issuer of the convertible securities or of another issuer; in each case, the form and 
amount of payment upon conversion is determined by the terms of the governing documents of the convertible 
securities. As a result, convertible securities have characteristics similar to both fixed-income and 
equity securities. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio may, but is not required to, (1) enter into interest rate, bond

put and call options on securities (including &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;shares 
of exchange-traded open-end management investment companies (&#x201c;ETFs&#x201d;)) and indexes, in each

under the Investment Company Act of 1940, as amended (the &#x201c;1940 Act&#x201d;), it may invest in a 
smaller number of issuers than other, more diversified investment portfolios.  In addition, implementation 
of the Portfolio&#x2019;s investment strategy may, during certain periods, result in the investment of 
a significant portion of the Portfolio&#x2019;s assets in a particular market sector.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

security also is subject to the same types of market and issuer risks that apply to the underlying common

decline due to general market conditions that are not specifically related to a particular company, such 
as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes 
in interest or currency rates or adverse investor sentiment generally. The debt securities market can 
be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably 
in response to overall economic conditions or credit tightening.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Prices 
of bonds and other debt securities tend to move inversely with changes in interest rates. Interest rate 
risk is usually greater for fixed-income securities with longer maturities or durations.  A rise in interest 
rates (or the expectation of a rise in interest rates) may result in periods of volatility, decreased 
liquidity and increased redemptions, and, as a result, the Portfolio may have to liquidate portfolio 
securities at disadvantageous prices. The Portfolio may be subject to heightened interest rate risk because 
the Federal Reserve has raised, and may continue to raise, interest rates. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio&#x2019;s 
investments in lower-rated, higher-yielding securities (&#x201c;junk bonds&#x201d;) are subject to greater 
credit risk than its higher rated investments. Credit risk is the risk that the issuer will not make 
interest or principal payments, or will not make payments on a timely basis. Non-investment grade securities 
tend to be more volatile, less liquid and are considered speculative. If there is a decline, or perceived 
decline, in the credit quality of a debt security (or any guarantor of payment on such security), the 
security&#x2019;s value could fall, potentially lowering the Portfolio&#x2019;s share price. The prices 
of non-investment grade securities, unlike investment grade debt securities, may fluctuate unpredictably 
and not necessarily inversely with changes in interest rates. The market for these securities may be 
less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially 
during times of market volatility or decline.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Some debt securities may give the issuer 
the option to call, or redeem, the securities before their maturity, and, during a time of declining 
interest rates, the Portfolio may have to reinvest the proceeds of called or redeemed securities in an 
investment offering a lower yield (and the Portfolio may not fully benefit from any increase in the value 
of its portfolio holdings as a result of declining interest rates).&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Adjustable rate securities provide the 
Portfolio with a certain degree of protection against rises in interest rates, although adjustable rate 
securities will participate in any declines in interest rates. Certain adjustable rate securities, such 
as those with interest rates that fluctuate directly or indirectly based on multiples of a stated index, 
are designed to be highly sensitive to changes in interest rates and can subject the holders thereof 
to extreme reductions of yield and possibly loss of principal. Certain fixed-income securities may be 
issued at a discount from their face value (such as zero coupon securities) or purchased at a price less 
than their stated face amount or at a price less than their issue price plus the portion of &#x201c;original 
issue discount&#x201d; previously accrued thereon, &lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;i.e.&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, purchased at 
a &#x201c;market discount.&#x201d; The amount of original issue discount and/or market discount on certain 
obligations may be significant, and accretion of market discount together with original issue discount 
will cause the Portfolio to realize income prior to the receipt of cash payments with respect to these 
securities.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

seeking to protect Portfolio investments), may increase volatility, reduce returns, limit gains or magnify 
losses, perhaps substantially, particularly since most derivatives have a leverage component that provides 
investment exposure in excess of the amount invested. Swap agreements and other over-the-counter derivatives 
transactions are subject to the risks of the creditworthiness of and default by the counterparty and 
consequently may lose all or a portion of their value due solely to the creditworthiness of or default 
by the counterparty. Over-the-counter derivatives frequently may be illiquid and difficult to value. 
Changes in liquidity may result in significant, rapid and unpredictable changes in the prices for derivatives. 
These derivatives transactions, as well as the exchange-traded futures and options in which the Portfolio 
may invest, are subject to many of the risks of, and can be highly sensitive to changes in the value 
of the related reference asset, index or rate. As such, a small investment could have a potentially large 
impact on the Portfolio&#x2019;s performance. In fact, many derivatives may be subject to greater risks 
than those associated with investing directly in the underlying or other reference asset. Derivatives 
transactions incur costs, either explicitly or implicitly, which reduce returns, and costs of engaging 
in such transactions may outweigh any gains or any losses averted from hedging activities. Successful 
use of derivatives, whether for hedging or for other investment purposes, is subject to the Investment 
Manager&#x2019;s ability to predict correctly movements in the direction of the relevant reference asset 
or market and, for hedging activities, correlation of the derivative instruments used with the investments 
seeking to be hedged. Use of derivatives transactions, even if entered into for hedging purposes, may 
cause the Portfolio to experience losses greater than if the Portfolio had not engaged in such transactions. 
When the Portfolio enters into derivatives transactions, it may be required to post margin and make settlement 
payments while the positions are open, and the Portfolio may have to sell a security at a disadvantageous 
time or price to meet such obligations. Derivatives transactions are also subject to operational and 
legal risk.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

After-tax returns of the Portfolio&#x2019;s other share classes will vary. After-tax returns are calculated 
using the historical highest individual marginal income tax rates and do not reflect the impact of state

from those shown. The after-tax returns shown are not relevant to investors who hold their shares through 
tax-deferred arrangements such as 401(k) plans or individual retirement accounts. Returns shown below 
for the Portfolio&#x2019;s R6 Shares (which were not operational as of December 31, 2024) reflect the 
performance of the Portfolio&#x2019;s Institutional Shares. R6 Shares would have had substantially similar 
returns as Institutional Shares because the share classes are invested in the same portfolio of securities,

The Portfolio has a concentrated number of investments, typically investing in 15 to 35 companies with

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

be influenced by political, social and economic factors affecting the non-US countries and companies 
in which the Portfolio invests. Non-US securities carry special risks, such as less developed or less 
efficient trading markets, political instability, a lack of company information, differing auditing and 
legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless. In addition, investments denominated 
in currencies other than US dollars may experience a decline in value, in US dollar terms, due solely 
to fluctuations in currency exchange rates.  Emerging market countries can generally have economic structures 
that are less diverse and mature, and political systems that are less stable, than those of developed 
countries.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets 
are increasingly interconnected, and conditions and events in one country, region or financial market 
may adversely impact issuers worldwide. As a result, local, regional or global events such as war or 
military conflict, acts of terrorism, the spread of infectious illness or other public health issues, 
social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply 
chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of 
sanctions or other similar measures, recessions or other events could have a significant negative impact 
on global economic and market conditions. For example, a public health or other emergency and aggressive 
responses taken by many governments or voluntarily imposed by private parties, including closing borders, 
restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure 
of, or operational changes to, many retail and other businesses, may have severe negative impacts on 
markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Small and mid cap companies carry additional risks because their earnings tend to be less predictable, 
their share prices more volatile and their securities less liquid than larger, more established companies. 
The shares of small and mid cap companies tend to trade less frequently than those of larger companies, 
which can have an adverse effect on the pricing of these securities and on the ability to sell these 
securities when the Investment Manager deems it appropriate.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries 
and companies in which the Portfolio invests. Non-US securities carry special risks, such as less developed 
or less efficient trading markets, political instability, a lack of company information, differing auditing 
and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless. In addition, investments denominated 
in currencies other than US dollars may experience a decline in value, in US dollar terms, due solely 
to fluctuations in currency exchange rates.  Emerging market countries can generally have economic structures 
that are less diverse and mature, and political systems that are less stable, than those of developed 
countries.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

may, during certain periods, result in the investment of a significant portion of the Portfolio&#x2019;s 
assets in a particular market sector, such as information technology companies, and the Portfolio would 
be expected to be affected by developments in that sector.  Information technology companies generally 
operate in intensely competitive markets on a worldwide basis.  Also, because technological development 
in many areas increases at a rapid rate, these companies often produce products with very short life 
cycles and face the risk of product obsolescence.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets 
are increasingly interconnected, and conditions and events in one country, region or financial market 
may adversely impact issuers worldwide. As a result, local, regional or global events such as war or 
military conflict, acts of terrorism, the spread of infectious illness or other public health issues, 
social unrest, natural disasters, extreme weather, other geological events, man-made disasters, supply 
chain disruptions, deflation, inflation, government defaults, government shutdowns, the imposition of 
sanctions or other similar measures, recessions or other events could have a significant negative impact 
on global economic and market conditions. For example, a public health or other emergency and aggressive 
responses taken by many governments or voluntarily imposed by private parties, including closing borders, 
restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure 
of, or operational changes to, many retail and other businesses, may have severe negative impacts on 
markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

The market value of a debt security may decline due to general market conditions that are not specifically 
related to a particular company, such as real or perceived adverse economic conditions, changes in the 
outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. 
The debt securities market can be susceptible to increases in volatility and decreases in liquidity. 
Liquidity can decline unpredictably in response to overall economic conditions or credit tightening.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Prices 
of bonds and other debt securities tend to move inversely with changes in interest rates. Interest rate 
risk is usually greater for fixed-income securities with longer maturities or durations.  A rise in interest 
rates (or the expectation of a rise in interest rates) may result in periods of volatility, decreased 
liquidity and increased redemptions, and, as a result, the Portfolio may have to liquidate portfolio 
securities at disadvantageous prices. The Portfolio may be subject to heightened interest rate risk because 
the Federal Reserve has raised, and may continue to raise, interest rates. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio&#x2019;s 
investments in lower-rated, higher-yielding securities (&#x201c;junk bonds&#x201d;) are subject to greater 
credit risk than its higher rated investments. Credit risk is the risk that the issuer will not make 
interest or principal payments, or will not make payments on a timely basis. Non-investment grade securities 
tend to be more volatile, less liquid and are considered speculative. If there is a decline, or perceived 
decline, in the credit quality of a debt security (or any guarantor of payment on such security), the 
security&#x2019;s value could fall, potentially lowering the Portfolio&#x2019;s share price. The prices 
of non-investment grade securities, unlike investment grade debt securities, may fluctuate unpredictably 
and not necessarily inversely with changes in interest rates. The market for these securities may be 
less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially 
during times of market volatility or decline.&lt;/p&gt;</rr:RiskTextBlock>

performance will be influenced by political, social and economic factors affecting the non-US countries 
and companies in which the Portfolio invests. Non-US securities carry special risks, such as less developed 
or less efficient trading markets, political instability, a lack of company information, differing auditing 
and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless. In addition, investments denominated 
in currencies other than US dollars may experience a decline in value, in US dollar terms, due solely 
to fluctuations in currency exchange rates.  Emerging market countries can generally have economic structures 
that are less diverse and mature, and political systems that are less stable, than those of developed 
countries.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

invests at least 80% of its assets in fixed-income securities of US issuers, including US government 
securities, corporate securities, mortgage-related and asset-backed securities, municipal securities, 
structured products, preferred stocks and inflation-indexed-securities. These securities may have any 
type of interest rate payment terms, including fixed rate, adjustable rate or zero coupon features. Under 
normal circumstances, the Portfolio&#x2019;s investment portfolio can be expected to have an average effective 
duration of three years or less. Duration is an estimate of the sensitivity of the price (the value of 
principal) of a fixed-income security to a change in interest rates. Generally, the longer the duration, 
the higher the expected volatility. For example, the market price of a fixed-income security with a duration 
of three years would be expected to decline 3% if interest rates rose 1%. Conversely, the market price 
of the same security would be expected to increase 3% if interest rates fell 1%.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio invests

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

The market value of a debt security may decline due to general market conditions that are not specifically 
related to a particular company, such as real or perceived adverse economic conditions, changes in the 
outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. 
The debt securities market can be susceptible to increases in volatility and decreases in liquidity. 
Liquidity can decline unpredictably in response to overall economic conditions or credit tightening.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Prices 
of bonds and other debt securities tend to move inversely with changes in interest rates. Interest rate 
risk is usually greater for fixed-income securities with longer maturities or durations.  A rise in interest 
rates (or the expectation of a rise in interest rates) may result in periods of volatility, decreased 
liquidity and increased redemptions, and, as a result, the Portfolio may have to liquidate portfolio 
securities at disadvantageous prices. The Portfolio may be subject to heightened interest rate risk because 
the Federal Reserve has raised, and may continue to raise, interest rates. &lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Portfolio&#x2019;s 
investments in lower-rated, higher-yielding securities (&#x201c;junk bonds&#x201d;) are subject to greater 
credit risk than its higher rated investments. Credit risk is the risk that the issuer will not make 
interest or principal payments, or will not make payments on a timely basis. Non-investment grade securities 
tend to be more volatile, less liquid and are considered speculative. If there is a decline, or perceived 
decline, in the credit quality of a debt security (or any guarantor of payment on such security), the 
security&#x2019;s value could fall, potentially lowering the Portfolio&#x2019;s share price. The prices 
of non-investment grade securities, unlike investment grade debt securities, may fluctuate unpredictably 
and not necessarily inversely with changes in interest rates. The market for these securities may be 
less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially 
during times of market volatility or decline.&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; font-style:normal;"&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;Adjustable rate securities provide the 
Portfolio with a certain degree of protection against rises in interest rates, although adjustable rate 
securities will participate in any declines in interest rates. Certain adjustable rate securities, such 
as those with interest rates that fluctuate directly or indirectly based on multiples of a stated index, 
are designed to be highly sensitive to changes in interest rates and can subject the holders thereof 
to extreme reductions of yield and possibly loss of principal. Certain fixed-income securities may be 
issued at a discount from their face value (such as zero coupon securities) or purchased at a price less 
than their stated face amount or at a price less than their issue price plus the portion of &#x201c;original 
issue discount&#x201d; previously accrued thereon, &lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:italic; font-weight:normal; text-decoration:none;"&gt;i.e.&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt;, purchased at 
a &#x201c;market discount.&#x201d; The amount of original issue discount and/or market discount on certain 
obligations may be significant, and accretion of market discount together with original issue discount 
will cause the Portfolio to realize income prior to the receipt of cash payments with respect to these 
securities.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

securities are complex instruments, subject to both credit and prepayment risk, and may be more volatile 
and less liquid, and more difficult to price accurately, than more traditional debt securities. Mortgage-related 
securities generally are subject to credit risks associated with the performance of the underlying mortgage 
properties. Prepayment risk can lead to fluctuations in value of the mortgage-related security which 
may be pronounced. As with other interest-bearing securities, the prices of certain mortgage-related 
securities are inversely affected by changes in interest rates. However, although the value of a mortgage-related 
security may decline when interest rates rise, the converse is not necessarily true, since during periods 
of declining interest rates the mortgages underlying the security are more likely to be prepaid.&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;The 
risks of asset-backed securities are similar to those of mortgage-related securities. However, asset-backed 
securities present certain risks that are not presented by mortgage-related securities. Primarily, these 
securities may provide the Portfolio with a less effective security interest in the related collateral 
than do mortgage-related securities.&lt;/p&gt;</rr:RiskTextBlock>

instruments where the principal and/or interest is determined by reference to a specified asset, market 
or rate, or the differential performance of two assets or markets. Structured products can have risks 
of both fixed-income securities and derivatives transactions. Derivatives transactions may increase volatility 
or reduce returns, perhaps substantially, particularly since most derivatives have a leverage component 
that provides investment exposure in excess of the amount invested, and they are subject to many of the 
risks of, and can be highly sensitive to changes in the value of, the related reference asset, market 
or rate. As such, a small investment could have a potentially large impact on the Portfolio&#x2019;s performance. 
Use of derivatives transactions may cause the Portfolio to experience losses greater than if the Portfolio 
had not engaged in such transactions.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

The Portfolio&#x2019;s investment strategy may involve high portfolio turnover (such as 100% or more). 
A portfolio turnover rate of 100%, for example, is equivalent to the Portfolio buying and selling all

high transaction costs and an increase in taxable capital gains distributions to the Portfolio&#x2019;s 
shareholders, which will reduce returns to shareholders.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

more markets in which it invests. These declines may be the result of, among other things, political, 
regulatory, market, economic or social developments affecting the relevant market(s). To the extent that 
such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio&#x2019;s 
investments in such industries, market sectors, countries and/or geographic regions can be expected to 
be particularly affected, especially if such investments are a significant portion of its investment 
portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or 
fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. 
Global economies and financial markets are increasingly interconnected, and conditions and events in 
one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional 
or global events such as war or military conflict, acts of terrorism, the spread of infectious illness 
or other public health issues, social unrest, natural disasters, extreme weather, other geological events, 
man-made disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

be influenced by political, social and economic factors affecting the non-US countries and companies 
in which the Portfolio invests. Non-US securities carry special risks, such as less developed or less 
efficient trading markets, political instability, a lack of company information, differing auditing and 
legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions 
or other governmental actions or developments, exchange controls (including repatriation restrictions), 
confiscations, trade restrictions (including tariffs) or problems related to share registration, trade 
settlement or asset&#160;custody, which could, among other things, effectively restrict or eliminate 
the Portfolio&#x2019;s ability to purchase or sell certain foreign securities. To the extent the Portfolio 
holds securities subject to such actions, the securities may become difficult to value and/or less liquid 
(or illiquid). In some cases, the securities may become worthless. In addition, investments denominated 
in currencies other than US dollars may experience a decline in value, in US dollar terms, due solely 
to fluctuations in currency exchange rates.  Emerging market countries can generally have economic structures 
that are less diverse and mature, and political systems that are less stable, than those of developed 
countries.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

expectations for future cash flows and profitability.  Next, the Investment Manager reduces the investable 
universe using fundamental analysis and research on the companies identified.  &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;In further narrowing 
the investable universe to select companies for investment by the Portfolio, the Investment Manager considers 
both (a) the financial sustainability of the company as a business&#x2014;a company whose financial productivity 
is likely to be supported or enhanced in the future as a result of the move toward a more sustainable 
world (such as by considering the nature of the products and/or services that the company provides, from 
the perspective of environmental and social factors that impact financial productivity)&#x2014;and (b) 
how the company counters potential risks arising as a result of environmental and social concerns that 
may be material to the particular companies or the industries or sectors in which they operate (collectively, 
&#x201c;Sustainable Companies&#x201d;).  The Investment Manager uses its proprietary sustainability analysis 
methodology to assess each company considered for investment, to the extent relevant to the company or 
its industry or sector, against the specific sustainability factors listed below (and other factors that 
may be considered relevant to the company or its industry), divided into the three categories of Human

may incur losses due to declines in one or more markets in which it invests. These declines may be the 
result of, among other things, political, regulatory, market, economic or social developments affecting 
the relevant market(s). To the extent that such developments impact specific industries, market sectors, 
countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market sectors, 
countries and/or geographic regions can be expected to be particularly affected, especially if such investments 
are a significant portion of its investment portfolio. In addition, turbulence in financial markets and 
reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which 
could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, 
and conditions and events in one country, region or financial market may adversely impact issuers worldwide. 
As a result, local, regional or global events such as war or military conflict, acts of terrorism, the 
spread of infectious illness or other public health issues, social unrest, natural disasters, extreme 
weather, other geological events, man-made disasters, supply chain disruptions, deflation, inflation, 
government defaults, government shutdowns, the imposition of sanctions or other similar measures, recessions 
or other events could have a significant negative impact on global economic and market conditions. For 
example, a public health or other emergency and aggressive responses taken by many governments or voluntarily 
imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines 
or similar restrictions, as well as the closure of, or operational changes to, many retail and other 
businesses, may have severe negative impacts on markets worldwide. Additionally, general market conditions 
may affect the value of a Portfolio&#x2019;s securities, including changes in interest rates, currency 
rates or monetary policies. Furthermore, the imposition of tariffs, trade restrictions, currency restrictions 
or similar actions (or retaliatory measures taken in response to such actions), or the threat or potential 
of one or more such events and developments, could lead to price volatility and overall declines in the 
US and global investment markets.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

those of developed countries. The economies of countries with emerging markets may be based predominantly 
on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and 
may suffer from extreme debt burdens or volatile inflation rates. Further, investments in securities 
of issuers located in certain emerging countries involve the risk of loss resulting from problems in 
share registration, settlement or custody, substantial economic, political and social disruptions and 
the imposition of sanctions or exchange controls (including repatriation restrictions). The securities 
markets of emerging market countries have historically been extremely volatile and less liquid than more 
developed markets. These market conditions may continue or worsen. Investments in these countries may 
be subject to political, economic, legal, market and currency risks. Significant devaluation of emerging 
market currencies against the US dollar may occur subsequent to acquisition of investments denominated 
in emerging market currencies.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

securities selection process to an investable universe of all publicly-traded equity securities, with 
a focus on small cap companies.  However, Automated Fundamental Analysts, which may change over time, 
may be applied to the broad market or specific to a particular sector or industry.  In addition, the 
selection process described above is not sequential, and certain criteria may be given more importance 
than others.  Target position sizes are determined at the time of investment based on the input of one 
or more Automated Fundamental Analysts and subsequently monitored on an ongoing basis.  To improve tax 
efficiency, the Portfolio may limit investments that have undesirable tax characteristics and may employ 
other tax-management techniques, such as adjusting the timing of trades, by relying in part on fundamental 
research and analytical judgements of the Investment Manager.&lt;/p&gt;</rr:StrategyNarrativeTextBlock>

The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines 
may be the result of, among other things, political, regulatory, market, economic or social developments 
affecting the relevant market(s). To the extent that such developments impact specific industries, market 
sectors, countries or geographic regions, the Portfolio&#x2019;s investments in such industries, market 
sectors, countries and/or geographic regions can be expected to be particularly affected, especially 
if such investments are a significant portion of its investment portfolio. In addition, turbulence in 
financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively 
affect many issuers, which could adversely affect the Portfolio. &lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;Global 
economies and financial markets are increasingly interconnected, and conditions and events in one country, 
region or financial market may adversely impact issuers worldwide. As a result, local, regional or global 
events such as war or military conflict, acts of terrorism, the spread of infectious illness or other 
public health issues, social unrest, natural disasters, extreme weather, other geological events, man-made 
disasters, supply chain disruptions, deflation, inflation, government defaults, government shutdowns, 
the imposition of sanctions or other similar measures, recessions or other events could have a significant 
negative impact on global economic and market conditions. For example, a public health or other emergency 
and aggressive responses taken by many governments or voluntarily imposed by private parties, including 
closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well 
as the closure of, or operational changes to, many retail and other businesses, may have severe negative 
impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio&#x2019;s 
securities, including changes in interest rates, currency rates or monetary policies. Furthermore, the 
imposition of tariffs, trade restrictions, currency restrictions or similar actions (or retaliatory measures 
taken in response to such actions), or the threat or potential of one or more such events and developments, 
could lead to price volatility and overall declines in the US and global investment markets.&lt;/p&gt;</rr:RiskTextBlock>

the effectiveness of the Investment Manager&#x2019;s quantitative model. A quantitative model, such as 
the risk and other models used by the Investment Manager requires adherence to a systematic, disciplined 
process. The Investment Manager&#x2019;s ability to monitor and, if necessary, adjust its quantitative 
model could be adversely affected by various factors including incorrect or outdated market and other 
data inputs. Factors that affect a security&#x2019;s value can change over time, and these changes may 
not be reflected in the quantitative model. In addition, factors used in quantitative analysis and the 
weight placed on those factors may not be predictive of a security&#x2019;s value.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

the risks associated with direct investments in the securities of non-US companies, because their values 
depend on the performance of the underlying non-US securities. However, currency fluctuations will impact 
investments in depositary receipts differently than direct investments in non-US dollar-denominated non-US 
securities, because a depositary receipt will not appreciate in value solely as a result of appreciation 
in the currency in which the underlying non-US dollar security is denominated.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

Risk:&lt;/span&gt;&lt;span style="font-size:10.0pt; font-family:Sans-Serif; font-style:normal; font-weight:normal; text-decoration:none;"&gt; The Portfolio&#x2019;s performance will be influenced by political, social and 
economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US 
securities carry special risks, such as less developed or less efficient trading markets, political instability, 
a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. 
Non-US securities may be subject to economic sanctions or other governmental actions or developments, 
exchange controls (including repatriation restrictions), confiscations, trade restrictions (including 
tariffs) or problems related to share registration, trade settlement or asset&#160;custody, which could, 
among other things, effectively restrict or eliminate the Portfolio&#x2019;s ability to purchase or sell 
certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the 
securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities 
may become worthless. In addition, investments denominated in currencies other than US dollars may experience 
&lt;/span&gt;&lt;/p&gt;&lt;p style="font-size:10.0pt; font-family:Sans-Serif; text-align:left; font-weight:normal; text-decoration:none;"&gt;a 
decline in value, in US dollar terms, due solely to fluctuations in currency exchange rates.  Emerging 
market countries can generally have economic structures that are less diverse and mature, and political 
systems that are less stable, than those of developed countries.&lt;/p&gt;</rr:RiskTextBlock>

of the Portfolio&#x2019;s investment strategy may, during certain periods, result in the investment of 
a significant portion of the Portfolio&#x2019;s assets in a particular market sector, such as information 
technology companies, and the Portfolio would be expected to be affected by developments in that sector. 
 Information technology companies generally operate in intensely competitive markets on a worldwide basis. 
 Also, because technological development in many areas increases at a rapid rate, these companies often 
produce products with very short life cycles and face the risk of product obsolescence.  &lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

buying and selling all of its securities once during the course of the year. A high portfolio turnover 
rate could result in high transaction costs and an increase in taxable capital gains distributions to 
the Portfolio&#x2019;s shareholders, which will reduce returns to shareholders.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>
