Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or&#160;instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index. Because the Fund is in its most conservative phase, its allocation generally does&#160;not become more conservative over time, although its allocation may change to maintain the Fund&#x2019;s risk profile.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk &lt;/span&gt;&#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk &lt;/span&gt;&#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Finally, BFA may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund&#x2019;s derivatives positions to lose value.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Counterparty Risk&lt;/span&gt; &#x2014; Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated exposure to such a counterparty.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Illiquidity Risk&lt;/span&gt; &#x2014; The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Operational Risk&lt;/span&gt; &#x2014; The use of derivatives includes the risk of potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Legal Risk&lt;/span&gt; &#x2014; The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Volatility and Correlation Risk&lt;/span&gt; &#x2014; Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund&#x2019;s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Valuation Risk &lt;/span&gt;&#x2014; Valuation for derivatives may not be readily available in the market.

The use of hedging may result in certain adverse tax consequences.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Tax Risk &lt;/span&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations.

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Neither the Fund nor its investment manager will independently review the bases for those tax opinions, which may ultimately be determined to be incorrect and subject the Fund and its shareholders to substantial tax liabilities.&lt;/div&gt; </oef:RiskTextBlock>

Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates.

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Institutional Shares of the Fund for each of the last ten calendar years. The average annual total returns table compares the performance of the Fund to that of the Bloomberg U.S. Aggregate Bond Index, the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and the LifePath Dynamic Retirement Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure IndexTM (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic Retirement Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic Retirement Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic Retirement Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and the LifePath Dynamic Retirement Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic Retirement Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure IndexTM (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic Retirement Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;have been lower.

Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2030. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;+/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non&#x2011;investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk &lt;/span&gt;&#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Relatively small market movements may result in large changes in the value of a derivatives position and can result in losses that greatly exceed the amount originally invested.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Market Risk&lt;/span&gt; &#x2014; Some derivatives are more sensitive to interest rate changes and market price fluctuations than other securities. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. Finally, BFA may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund&#x2019;s derivatives positions to lose value.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Counterparty Risk&lt;/span&gt; &#x2014; Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated exposure to such a counterparty.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Illiquidity Risk&lt;/span&gt; &#x2014; The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Operational Risk&lt;/span&gt; &#x2014; The use of derivatives includes the risk of potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Legal Risk&lt;/span&gt; &#x2014; The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Volatility and Correlation Risk&lt;/span&gt; &#x2014; Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund&#x2019;s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Valuation Risk &lt;/span&gt;&#x2014; Valuation for derivatives may not be readily available in the market. Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Hedging Risk&lt;/span&gt; &#x2014; Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund&#x2019;s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Tax Risk &lt;/span&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations.

The Fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. In addition, distressed securities involve the substantial risk that principal will not be repaid. These securities may present a substantial risk of default or may be in default at the time of investment. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in an exchange for such securities may be subject to restrictions on resale.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company&#x2019;s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it could suffer losses in excess of the value of its TOB Residuals.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Thus, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Institutional Shares of the Fund for each of the last ten calendar years. The average annual total returns table compares the performance of the Fund to that of the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2030 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0&#x2011;5&#160;Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2030 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2030 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2030 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2030 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2030 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2030 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover rate was 13% of the average value of its portfolio.&lt;/div&gt; </oef:PortfolioTurnoverTextBlock>

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2035. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a greater&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non&#x2011;investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations.

Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts. While depositary receipts provide an alternative to directly purchasing underlying foreign securities in their respective markets and currencies, they continue to be subject to many of the risks associated with investing directly in foreign securities, including political, economic, and currency risk.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

In addition, distressed securities involve the substantial risk that principal will not be repaid. These securities may present a substantial risk of default or may be in default at the time of investment. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in an exchange for such securities may be subject to restrictions on resale.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Neither an Underlying Fund nor BFA can offer assurances that the index provider&#x2019;s methodology or sources of information will provide an accurate assessment of included components. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the index provider may not identify or correct them promptly or at all, which may have an adverse impact on an Underlying Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the index provider or a third-party data provider and could cause the index provider to postpone a scheduled rebalance. This could cause an underlying index to vary from its normal or expected composition.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

The market price of pay-in-kind bonds is affected by interest rate changes to a greater extent, and therefore tends to be more volatile, than that of securities which pay interest in cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it could suffer losses in excess of the value of its TOB Residuals.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

These risks may be heightened during times of increased market volatility or other unusual market conditions.

A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Thus, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Institutional Shares of the Fund for each of the last ten calendar years. The average annual total returns table compares the performance of the Fund to that of the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2035 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2035 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2035 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2035 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2035 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2035 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July&#160;29, 2022, the LifePath Dynamic 2035 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March&#160;31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March&#160;31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii)&#160;increase the flexibility of its equity allocations and (iii)&#160;diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt; </oef:PortfolioTurnoverTextBlock>

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2040. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non&#x2011;investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations.

In addition, distressed securities involve the substantial risk that principal will not be repaid.

The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment.

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

&lt;td style="vertical-align: top;"&gt; &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-family: arial; font-size: 10pt;"&gt;market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis.

Mortgage-related securities guaranteed by the Government National Mortgage Association (&#x201c;GNMA&#x201d; or &#x201c;Ginnie Mae&#x201d;) are guaranteed as to the timely payment of principal and interest by GNMA and such guarantee is backed by the full faith and credit of the United States. GNMA securities also are supported by the right of GNMA to borrow funds from the U.S. Treasury to make payments under its guarantee. Mortgage-related securities issued by Fannie Mae or Freddie Mac are solely the obligations of Fannie Mae or Freddie Mac, as the case may be, and are not backed by or entitled to the full faith and credit of the United States but are supported by the right of the issuer to borrow from the Treasury.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2040 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2040 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2040 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2040 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2040 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0&#x2011;5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#x2122;&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index.

Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii)&#160;increase the flexibility of its equity allocations and (iii)&#160;diversify its fixed-income strategies.

These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#x2019;s performance.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2045. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non&#x2011;investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

For example, the Fund indirectly pays a portion of the expenses (including operating expenses and management fees) incurred by the Underlying Funds.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non-payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non-recourse or recourse basis.

GNMA securities also are supported by the right of GNMA to borrow funds from the U.S. Treasury to make payments under its guarantee.

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2045 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2045 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2045 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2045 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2045 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#x2122;&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2045 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii)&#160;increase the flexibility of its equity allocations and (iii)&#160;diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2050. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non-investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments.

If an underlying fund or ETF holds interests in an affiliated fund, the Fund may be prohibited from purchasing shares of that underlying fund or ETF.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis.

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2050 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2050 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2050 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2050 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2050 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#x2122;&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2050 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March&#160;31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii)&#160;diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5%&#160;return each year and that the Fund&#x2019;s operating expenses remain the same.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2055. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non-investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments.

As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis.

Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts. While depositary receipts provide an alternative to directly purchasing underlying foreign securities in their respective markets and currencies, they continue to be subject to many of the risks associated with investing directly in foreign securities, including political, economic, and currency risk.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2055 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2055 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2055 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2055 Fund Custom Benchmark are relevant to the Fund because they&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2055 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#x2122;&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2055 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March&#160;31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March&#160;31, 2018 is based on the prior target asset allocation. Effective November&#160;7, 2016, the Fund changed its investment strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii)&#160;increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November&#160;7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated&#160;open&#x2011;end&#160;funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2060. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality&#160;(including&#160;non-investment&#160;grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest, principal or dividends when due, and their market value may change based on changes in the issuer&#x2019;s credit rating or the market&#x2019;s perception of the issuer&#x2019;s creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock, including the potential for increased volatility in the price of the convertible security.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts.

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Reverse repurchase agreements involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and the value of the collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of the securities. These events could also trigger adverse tax consequences for the Fund. In addition, reverse repurchase agreements involve the risk that the interest income earned in the investment of the proceeds will be less than the interest expense.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security&#x2019;s price.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Institutional Shares of the Fund for its eight complete calendar years of operations. The average annual total returns table compares the performance of the Fund to that of the Russell 1000&#xae; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2060 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&#xae; Index and Russell 2000&#xae; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2060 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2060 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2060 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2060 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November&#160;1, 2024, the&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;LifePath Dynamic 2060 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM &lt;/sup&gt;(Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July&#160;29, 2022, the LifePath Dynamic 2060 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March&#160;31, 2018 is based on the prior target asset allocation. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in&#160;affiliated&#160;open&#x2011;end&#160;funds&#160;and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2065. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

In general, the adjustments will be limited to +/- 10% relative to the target allocations.&lt;/div&gt; &lt;/td&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/&#x2011;&#160;10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including&#160;non&#x2011;investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The market price of pay-in-kind bonds is affected by interest rate changes to a greater extent, and therefore tends to be more volatile, than that of securities which pay interest in cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company&#x2019;s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The average annual total returns table compares the performance of the Fund to that of the Russell 1000&#xae; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2065 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&#xae; Index and Russell 2000&#xae; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2065 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2065 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2065 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2065 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy.

These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#x2019;s performance.

Under normal circumstances, the Fund intends to invest primarily in affiliated open&#x2011;end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2070. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

In general, the adjustments will be limited to +/- 10% relative to the target allocations.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The table shown above depicts only the asset allocation between equity and fixed income investments. The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investment in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non&#x2011;investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies.

Relatively small market movements may result in large changes in the value of a derivatives position and can result in losses that greatly exceed the amount originally invested.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Market Risk &lt;/span&gt;&#x2014; Some derivatives are more sensitive to interest rate changes and market price fluctuations than other securities. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. Finally, BFA may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund&#x2019;s derivatives positions to lose value.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Counterparty Risk &lt;/span&gt;&#x2014; Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated exposure to such a counterparty.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Illiquidity Risk &lt;/span&gt;&#x2014; The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Operational Risk &lt;/span&gt;&#x2014; The use of derivatives includes the risk of potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Legal Risk &lt;/span&gt;&#x2014; The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Volatility and Correlation Risk &lt;/span&gt;&#x2014; Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund&#x2019;s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Valuation Risk &lt;/span&gt;&#x2014; Valuation for derivatives may not be readily available in the market. Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Hedging Risk &lt;/span&gt;&#x2014; Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund&#x2019;s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Tax Risk &lt;/span&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations.

For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid&#x2011;ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The average annual total returns table compares the performance of the Fund to that of the Russell 1000&#xae; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2070 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&#xae; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure IndexTM (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&#xae; Index and Russell 2000&#xae; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2070 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2070 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2070 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2070 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy.

To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees and sales charges. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index. Because the Fund is in its most conservative phase, its allocation generally does not become more conservative over time, although its allocation may change to maintain the Fund&#x2019;s risk profile.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type.

The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index.

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The purchase of structured notes exposes the Fund to the credit risk of the issuer of the structured product. Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it could suffer losses in excess of the value of its TOB Residuals.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions.

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Class K Shares of the Fund for each of the last ten calendar years, except as described below. The average annual total returns table compares the performance of the Fund to that of the Bloomberg U.S. Aggregate Bond Index, the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and the LifePath Dynamic Retirement Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure IndexTM (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic Retirement Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic Retirement Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic Retirement Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and the LifePath Dynamic Retirement Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy.

Effective July 29, 2022, the LifePath Dynamic Retirement Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2030. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk &lt;/span&gt;&#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk &lt;/span&gt;&#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

In addition, many emerging financial markets have far lower trading volumes and less liquidity than developed markets.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Neither the Fund nor its investment manager will independently review the bases for those tax opinions, which may ultimately be determined to be incorrect and subject the Fund and its shareholders to substantial tax liabilities.&lt;/div&gt; </oef:RiskTextBlock>

Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The purchase of structured notes exposes the Fund to the credit risk of the issuer of the structured product. Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it could suffer losses in excess of the value of its TOB Residuals.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The average annual total returns table compares the performance of the Fund to that of the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2030 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2030 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2030 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2030 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2030 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2030 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July&#160;29, 2022, the LifePath Dynamic 2030 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March&#160;31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November&#160;7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the&#160;flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November&#160;7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2035. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Mortgage- and asset-backed securities are subject to credit, interest rate, prepayment and extension risks. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its full faith, credit and taxing power for repayment.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Moral Obligation Bonds Risks &lt;/span&gt;&#x2014; Moral obligation bonds are generally issued by special purpose public authorities of a state or municipality. If the issuer is unable to meet its obligations, repayment of these bonds becomes a moral commitment, but not a legal obligation, of the state or municipality.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Municipal Notes Risks &lt;/span&gt;&#x2014; Municipal notes are shorter term municipal debt obligations.

Although the issuer does not pledge its unlimited taxing power for payment of the lease obligation, the lease obligation is secured by the leased property.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Tax&#x2011;Exempt Status Risk &lt;/span&gt;&#x2014; The Fund and its investment manager will rely on the opinion of issuers&#x2019; bond counsel and, in the case of derivative securities, sponsors&#x2019; counsel, on the tax&#x2011;exempt status of interest on municipal bonds and payments under derivative securities. Neither the Fund nor its investment manager will independently review the bases for those tax opinions, which may ultimately be determined to be incorrect and subject the Fund and its shareholders to substantial tax liabilities.&lt;/div&gt; </oef:RiskTextBlock>

Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company&#x2019;s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index.

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set&#x2011;off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis.

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2035 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath&#160;Dynamic 2035 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2035 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2035 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2035 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index.

Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November&#160;7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii)&#160;diversify its fixed-income strategies. Performance for the periods shown prior to November&#160;7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s portfolio turnover rate was 16% of the average value of its portfolio.&lt;/div&gt; </oef:PortfolioTurnoverTextBlock>

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2040. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts.

In addition, distressed securities involve the substantial risk that principal will not be repaid. These securities may present a substantial risk of default or may be in default at the time of investment. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment.

Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the index provider may not identify or correct them promptly or at all, which may have an adverse impact on an Underlying Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the index provider or a third-party data provider and could cause the index provider to postpone a scheduled rebalance.

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

In addition, a company&#x2019;s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set&#x2011;off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation.

An economic downturn generally leads to a higher non&#x2011;payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non&#x2011;payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The purchase of structured notes exposes the Fund to the credit risk of the issuer of the structured product. Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non&#x2011;recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it could suffer losses in excess of the value of its TOB Residuals.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Thus, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Class K Shares of the Fund for each of the last ten calendar years, except as described below. The average annual total returns table compares the performance of the Fund to that of the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2040 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure IndexTM (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2040 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2040 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2040 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2040 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2040 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure IndexTM (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2040 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2045. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of historically low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Prepayment Risk&lt;/span&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/div&gt; </oef:RiskTextBlock>

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.&lt;/div&gt; </oef:RiskTextBlock>

Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities.

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non-payment rate, and a senior loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund may have the right to receive payments only from the structured security, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may decline in value or default; and the possibility that the structured securities are subordinate to other classes. The Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement transactions, and there currently is no active trading market for structured securities. Structured securities are based upon the movement of one or more factors, including currency exchange rates, interest rates, reference bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on residual inverse floating rate interest tender option bonds (&#x201c;TOB Residuals&#x201d; will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. TOB Residuals generally will underperform the market for fixed rate municipal securities in a rising interest rate environment. The Fund may invest in beneficial interests in a special purpose trust formed for the purpose of holding municipal bonds or other municipal securities contributed by one or more funds (a &#x201c;TOB Trust&#x201d;) on either a non-recourse or recourse basis. If the Fund invests in a TOB Trust on a recourse basis, it could suffer losses in excess of the value of its TOB Residuals.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. These securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from variable and floating rate securities held by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

The weightings of the indices in the LifePath Dynamic 2045 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2045 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2045 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2045 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2045 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&#xae; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure IndexTM (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2045 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November 7, 2016, the Fund changed its investment strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower. Updated information on the Fund&#x2019;s performance, including its current net asset value, can be obtained by visiting http://www.blackrock.com or can be obtained by phone at (800) 882-0052.&lt;/div&gt; </oef:PerformanceNarrativeTextBlock>

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2050. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments.

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

In addition to investment risks associated with the underlying issuer, depositary receipts expose the Fund to additional risks associated with the non&#x2011;uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and the risk of an illiquid market for depositary receipts.&#160;The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material. Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts. While depositary receipts provide an alternative to directly purchasing underlying foreign securities in their respective markets and currencies, they continue to be subject to many of the risks associated with investing directly in foreign securities, including political, economic, and currency risk.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2050 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2050 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2050 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2050 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2050 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2050 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November&#160;7, 2016, the Fund changed its investment strategy to (i)&#160;incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii)&#160;diversify its fixed-income strategies. Performance for the periods shown prior to November 7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund&#x2019;s operating expenses remain the same.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#x2019;s performance.

Under normal circumstances, the Fund intends to invest primarily in affiliated open-end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2055. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments.

The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. Finally, BFA may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund&#x2019;s derivatives positions to lose value.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Counterparty Risk&lt;/span&gt; &#x2014; Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated exposure to such a counterparty.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Illiquidity Risk&lt;/span&gt; &#x2014; The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Operational Risk&lt;/span&gt; &#x2014; The use of derivatives includes the risk of potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Legal Risk&lt;/span&gt; &#x2014; The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Volatility and Correlation Risk&lt;/span&gt; &#x2014; Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund&#x2019;s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Valuation Risk &lt;/span&gt;&#x2014; Valuation for derivatives may not be readily available in the market. Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Hedging Risk&lt;/span&gt; &#x2014; Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund&#x2019;s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Tax Risk &lt;/span&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations.

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The Fund could lose money if it is unable to recover the securities and the value of the collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of the securities.

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds,&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The purchase of structured notes exposes the Fund to the credit risk of the issuer of the structured product. Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

In addition, notwithstanding that U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal, such as reaching the legislative &#x201c;debt ceiling.&#x201d; Such non-payment could result in losses to the Fund and substantial negative consequences for the U.S. economy and the global financial system.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The weightings of the indices in the LifePath Dynamic 2055 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2055 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2055 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2055 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2055 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2055 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. Effective November&#160;7, 2016, the Fund changed its investment strategy to (i) incorporate a Global Tactical Asset Allocation into its glidepath, (ii) increase the flexibility of its equity allocations and (iii) diversify its fixed-income strategies. Performance for the periods shown prior to November&#160;7, 2016 is based on the prior investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated&#160;open&#x2011;end&#160;funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2060. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non-investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments.

Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Hedging Risk&lt;/span&gt; &#x2014; Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund&#x2019;s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; margin-left: 3%; font-size: 10pt; font-family: arial;"&gt;&lt;span style="font-style: italic;"&gt;Tax Risk &lt;/span&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units,&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The purchase of structured notes exposes the Fund to the credit risk of the issuer of the structured product. Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund. In addition, notwithstanding that U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal, such as reaching the legislative &#x201c;debt ceiling.&#x201d; Such non-payment could result in losses to the Fund and substantial negative consequences for the U.S. economy and the global financial system.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Class K Shares of the Fund for its eight complete calendar years of operations. The average annual total returns table compares the performance of the Fund to that of the Russell 1000&#xae; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2060 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&#xae; U.S. Treasury 0-5&#160;Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&#xae; Index and Russell 2000&#xae; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2060 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2060 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2060 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2060 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2060 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&#xae; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2060 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. Effective March 31, 2018, the investment adviser determined not to allocate any of the Fund&#x2019;s assets to underlying funds that invest primarily in commodities. Performance for the periods shown prior to March 31, 2018 is based on the prior target asset allocation. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Updated information on the Fund&#x2019;s performance, including its current net asset value, can be obtained by visiting http://www.blackrock.com or can be obtained by phone at (800) 882-0052.&lt;/div&gt; </oef:PerformanceNarrativeTextBlock>

Under normal circumstances, the Fund intends to invest primarily in&#160;affiliated&#160;open&#x2011;end&#160;funds&#160;and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2065. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non&#x2011;investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.&lt;/div&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The market price of pay-in-kind bonds is affected by interest rate changes to a greater extent, and therefore tends to be more volatile, than that of securities which pay interest in cash.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company&#x2019;s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The per share net asset value of an ETF is calculated at the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Tracking error may occur because of differences between the securities (including shares of the Underlying Funds) and other assets held in an Underlying Fund&#x2019;s portfolio and those included in its underlying index, pricing differences including, as applicable, differences between a security&#x2019;s price at the local market close and an Underlying Fund&#x2019;s valuation of a security at the time of calculation of an Underlying Fund&#x2019;s net asset value, differences in the timing and methodologies used to value securities and other assets, transaction costs and other expenses incurred by an Underlying Fund that the Underlying Index does not incur, an Underlying Fund&#x2019;s holding of uninvested cash, differences in the timing of the accrual of or the valuation of dividends or interest received by an Underlying Fund or distributions paid to an Underlying Fund shareholders, tax gains or losses, differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from an Underlying Fund&#x2019;s obligation, if any, for foreign withholding taxes, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, the acceptance of custom baskets, changes to an underlying index and the cost to an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. These risks may be heightened during times of increased market volatility or other unusual market conditions. In addition, tracking error may result because a fund incurs fees and expenses, while the Underlying Index does not.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

In addition, notwithstanding that U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal, such as reaching the legislative &#x201c;debt ceiling.&#x201d; Such non-payment could result in losses to the Fund and substantial negative consequences for the U.S. economy and the global financial system.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The average annual total returns table compares the performance of the Fund to that of the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2065 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0&#x2011;5&#160;Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter-end. The weightings of the indices in the LifePath Dynamic 2065 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2065 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2065 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2065 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November 1, 2024, the LifePath Dynamic 2065 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0-5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and FTSE EPRA Nareit Developed Index. Effective July 29, 2022, the LifePath Dynamic 2065 Fund Custom Benchmark against which the Fund measures its performance was changed to remove Bloomberg U.S. Aggregate Bond Index and to add Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index and Bloomberg U.S. Securitized: MBS, ABS and CMBS Index. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Under normal circumstances, the Fund intends to invest primarily in affiliated open&#x2011;end funds and affiliated exchange-traded funds (&#x201c;ETFs&#x201d;), some of which may be index funds.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may, when consistent with its investment goal, buy or sell options or futures, or enter into total return swaps and foreign currency transactions (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may use derivatives as a substitute for taking a position in an Underlying Fund and/or as part of a strategy to reduce exposure to certain risks. The Fund may also use derivatives to enhance return, in which case their use may involve leveraging risk. Derivatives generally will increase or decrease the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path by the notional amount of such derivatives, except that derivatives used to manage currency exposure will not be allocated to the Fund&#x2019;s equity or fixed income allocations for purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund may invest up to 10% of its net assets in Underlying Funds that are multi-asset funds designed to have a lower correlation to traditional assets such as equities or fixed income (such Underlying Funds, &#x201c;Tactical Allocation Underlying Funds&#x201d;). The allocation to such Tactical Allocation Underlying Funds is designed to seek to improve overall portfolio diversification and enhance returns. Allocations to such Tactical Allocation Underlying Funds will not be allocated to the Fund&#x2019;s equity or fixed income allocations for the purposes of the glide path.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The Fund is designed for investors expecting to retire or to begin withdrawing assets around the year 2070. The Fund seeks to provide for retirement outcomes based on quantitatively measured risk. BFA employs a multi-dimensional approach to assess risk for the Fund and to determine the Fund&#x2019;s allocation across asset classes. As part of this multi-dimensional approach, BFA aims to quantify risk using proprietary risk measurement tools that, among other things, analyze historical and forward-looking securities market data, including risk, asset class correlations, and expected returns. Certain Underlying Funds may invest in equity securities of issuers that are primarily engaged in or related to the real estate industry, real estate investment trusts (&#x201c;REITs&#x201d;), infrastructure companies, foreign securities, emerging market securities, below investment-grade bonds, commodity-related instruments and derivative securities or instruments, such as options and futures, the value of which is derived from another security, a commodity, a currency or an index.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Under normal circumstances, the asset allocation between equity and fixed income assets will change over time according to a &#x201c;glide path&#x201d; as the Fund approaches its target date. The glide path below represents the shifting of these two asset classes over time. As the glide path shows, the Fund&#x2019;s asset mix between equity and fixed income assets becomes more conservative &#x2014; prior to retirement &#x2014; as time elapses. This reflects the need for reduced investment risks as retirement approaches and the need for lower volatility of the Fund, which may be a primary source of income after retirement.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The following chart illustrates the glide path &#x2014; the target allocation to the equity asset class as the Fund approaches its target date.&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; text-align: center;"&gt;

The Fund may also invest in Tactical Allocation Underlying Funds, which will not be allocated towards the equity and fixed income percentages listed for the glide path. The Fund&#x2019;s investments in money market funds also will not be allocated towards the equity and fixed income percentages listed for the glide path. This means that in considering the glide path, you should understand that it is not a complete representation of the Fund&#x2019;s portfolio. It shows only how the Fund generally allocates assets between equity and fixed income investments as a percentage of the Fund&#x2019;s net assets, and notwithstanding that it shows figures that add up to 100%, it does not account for the Fund&#x2019;s investments in other asset classes (which can include Tactical Allocation Underlying Funds, currency exposure or money market funds).&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;The asset allocation targets are established by the portfolio managers. The investment team, including the portfolio managers, meets regularly to assess market conditions, review the asset allocation targets of the Fund, and determine whether any changes are required to enable the Fund to achieve its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Although the asset allocation targets among equity and fixed income assets listed for the glide path (each as a percentage of the Fund&#x2019;s net assets) are general, long-term targets, BFA may adjust the allocation to equity and fixed income in the Fund, based on an assessment of the current market conditions and the potential contribution of each asset class to the expected risk and return characteristics of the Fund. In general, the adjustments will be limited to +/- 10% relative to the target allocations. At notional value after such adjustments, the Fund&#x2019;s equity allocation could exceed 100%. BFA may determine, in light of market conditions or other factors, that a greater variation is warranted to protect the Fund or achieve its investment objective. Investments in equity and fixed income Underlying Funds will be allocated towards the equity and fixed income percentages based on their classification.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;BFA&#x2019;s second step in the structuring of the Fund is the selection of the Underlying Funds and derivatives. Factors such as fund classifications, historical risk and performance, and the relationship to other Underlying Funds in the Fund are considered when selecting Underlying Funds. The specific Underlying Funds selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective. See the &#x201c;Details About the Funds &#x2014; Information About the Underlying Funds&#x201d; section of the prospectus for a list of the Underlying Funds, their classification into equity, fixed income, Tactical Allocation or money market funds and a brief description of their investment objectives and primary investment strategies. The specific derivatives selected for the Fund are determined at BFA&#x2019;s discretion and may change as deemed appropriate to allow the Fund to meet its investment objective.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"&gt;Within the prescribed percentage allocations to equity and fixed income, BFA seeks to diversify the Fund. The equity allocation may be further diversified by style (including both value and growth funds and issuers), market capitalization (including large cap, mid cap, small cap and emerging growth funds and issuers), region (including domestic and international (including emerging market) funds and issuers) or other factors. The fixed income allocation may be further diversified by sector (including government, corporate, agency, and other sectors), duration (a calculation of the average life of a bond which measures its price risk), credit quality (including non&#x2011;investment grade debt or junk bonds), geographic location (including U.S. and foreign-issued securities), or other factors. Though BFA seeks to diversify the Fund, certain Underlying Funds may concentrate their investments in specific sectors or geographic regions or countries. The percentage allocation to the various styles of equity and fixed income are determined at the discretion of the investment team and can be changed to reflect the current market environment.&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, or other events could have a significant impact on the Fund and its investments.

In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest, principal or dividends when due, and their market value may change based on changes in the issuer&#x2019;s credit rating or the market&#x2019;s perception of the issuer&#x2019;s creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock, including the potential for increased volatility in the price of the convertible security.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material. Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts.

If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

An ETF may or may not hold every security in the index. When an ETF deviates from a full replication indexing strategy to utilize a representative sampling strategy, the ETF is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the ETF may not have an investment profile similar to those of its index.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s shares trading at a premium or discount to net asset value. However, because shares can be created and redeemed in creation units, which are aggregated blocks of shares that authorized participants who have entered into agreements with the ETF&#x2019;s distributor can purchase or redeem directly from the ETF, at net asset value (unlike shares of many closed&#x2011;end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset values), large discounts or premiums to the net asset value of an ETF are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a time when the market price is at a premium to the net asset value or sells at a time when the market price is at a discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions may also cause the ETFs&#x2019; shares to trade in the market at greater bid&#x2011;ask spreads or greater premiums or discounts to the ETFs&#x2019; net asset value.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </oef:RiskTextBlock>

The bar chart shows the returns for Class&#160;K Shares of the Fund for its first full calendar year of operations. The average annual total returns table compares the performance of the Fund to that of the Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, the Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2070 Fund Custom Benchmark, a customized weighted index comprised of the Bloomberg U.S. Long Credit Bond Index, Bloomberg U.S. Intermediate Credit Bond Index, Bloomberg U.S. Long Government Bond Index, Bloomberg U.S. Intermediate Government Bond Index, Bloomberg U.S. Securitized: MBS, ABS and CMBS Index, ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0&#x2011;5&#160;Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index, S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net), MSCI&#160;ACWI ex USA IMI Index (Net), Russell 1000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index and Russell 2000&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; Index, which are representative of the asset classes in which the Fund invests according to their weightings as of the most recent quarter&#x2011;end. The weightings of the indices in the LifePath Dynamic 2070 Fund Custom Benchmark are adjusted periodically to reflect the investment adviser&#x2019;s evaluation and adjustment of the Fund&#x2019;s asset allocation strategy. The returns of the LifePath Dynamic 2070 Fund Custom Benchmark shown in the average annual total returns table are not recalculated or restated when they are adjusted to reflect the Fund&#x2019;s asset allocation strategy but rather reflect the LifePath Dynamic 2070 Fund Custom Benchmark&#x2019;s actual allocation over time, which may be different from the current allocation. The Bloomberg U.S. Aggregate Bond Index and the LifePath Dynamic 2070 Fund Custom Benchmark are relevant to the Fund because they have characteristics similar to the Fund&#x2019;s investment strategy. Effective November&#160;1, 2024, the LifePath Dynamic 2070 Fund Custom Benchmark against which the Fund measures its performance was changed to add ICE&lt;sup style="font-size: 75%; vertical-align: top;"&gt;&#xae;&lt;/sup&gt; U.S. Treasury 0&#x2011;5 Year Inflation Linked Bond Index, FTSE Nareit All Equity REIT Index and S&amp;amp;P Global Infrastructure Index&lt;sup style="font-size: 75%; vertical-align: top;"&gt;TM&lt;/sup&gt; (Net) and to gradually remove Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series&#x2011;L) and FTSE EPRA Nareit Developed Index. To the extent that dividends and distributions have been paid by the Fund, the performance information of the Fund in the chart and table assumes reinvestment of the dividends and distributions. The table includes all applicable fees. How the Fund performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. If BFA, BAL and their affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</xhtml:div></link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</xhtml:div></link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</xhtml:div></link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>
