Investment Objective

The High Yield Bond Fund seeks to maximize long-term total return consistent with preservation of capital.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. 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’s operating expenses remain the same. The cost for the Fund reflects the net expenses of the Fund that result from the Class I-3 contractual expense limitation in the first year only (through [ ]). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 76% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in high yield bonds (commonly known as “junk bonds”), which are bonds rated below investment grade or unrated bonds determined by the Adviser to be of comparable quality. The remainder of the Fund’s net assets may be invested in investment grade securities rated by one of the nationally recognized statistical rating organizations or, if unrated, determined by the Adviser to be of comparable quality.

Under normal circumstances, the Fund’s portfolio duration is two to eight years and the Fund’s dollar-weighted average maturity ranges from two to fifteen years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security to changes in interest rates. The Fund invests in the U.S. and abroad, including emerging markets, and may purchase securities of varying maturities issued by domestic and foreign corporations and governments. The Adviser focuses the Fund’s portfolio holdings in areas of the bond market that the Adviser believes to be relatively undervalued, based on its analysis of quality, sector, coupon or maturity, and that the Adviser believes offer attractive prospective risk-adjusted returns compared to other segments of the bond market. The Fund may invest up to 25% of its assets in foreign securities that are denominated in U.S. dollars. The Fund may invest up to 15% of its assets in securities of foreign issuers that are not denominated in U.S. dollars. The Fund may invest up to 10% of its assets in emerging market securities.

The Fund’s investments include various types of bonds and debt securities, including corporate bonds, mezzanine investments, swaps (including credit default swaps), currency futures and options, bank loans, preferred stock, mortgage-related and asset-backed securities (including collateralized debt obligations, which in turn include collateralized bond obligations and collateralized loan obligations), foreign securities, U.S. Treasuries and agency securities, private placements, defaulted debt securities and restricted securities, cash and cash equivalents; and common stocks or other equity securities, such as warrants. The Fund’s fixed income investments may have interest rates that are fixed, variable or floating.

Derivatives are used in an effort to hedge investments, for risk management, or to increase income or gains for the Fund. The Fund may also seek to obtain market exposure to the securities in which it invests by entering into a series of purchase and sale contracts or by using other investment techniques such as reverse repurchase agreements. The Fund may normally borrow or short sell up to 33 1/3% of the value of its total assets. The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.

Principal Risks

Because the Fund holds securities with fluctuating market prices, the value of the Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund.

The principal risks affecting the Fund that can cause a decline in value are:

Please see “Principal Risks” and “Other Risks” for a more detailed description of the risks of investing in the Fund.

Your investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, entity, or person.

Performance Information

The following bar chart and table provide some indication of the risks of investing in the Fund. Because Class I-3 has not commenced operations as of the date of this prospectus, the bar chart shows performance for the Fund’s Class M shares and the table shows annual total returns for the Fund’s Class M and Class I shares. Class M and Class I shares would have substantially similar annual returns to Class I-3 shares because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that Class M and Class I shares do not have the same expenses as Class I-3 shares. Performance information for Class I-3 shares will be provided after such shares have one full calendar year of performance.

The bar chart shows changes in the Fund’s performance from year to year. The table compares the average annual total returns of the Fund to a broad-based securities market index and a secondary benchmark index. Total returns would have been lower if certain fees and expenses had not been waived or reimbursed. The inception dates of Class M shares and Class I shares of the Fund are September 30, 2002 and March 31, 2003, respectively. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown for only Class M Shares. After-tax returns for other classes will vary. In some cases, returns after taxes on distributions and sale of Fund shares may be higher than returns before taxes because the calculations assume that the investor received a tax deduction for any loss incurred on the sale of the shares.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 454% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its objective by investing, under normal circumstances, at least 70% of its net assets in highly rated fixed income securities or unrated securities determined by the Adviser to be of comparable quality. Up to 30% of the Fund’s net assets may be invested in securities rated below highly rated securities or unrated securities determined by the Adviser to be of comparable quality, but not more than 20% of the Fund’s net assets may be invested in securities rated below investment grade (commonly known as “junk bonds”) or unrated securities determined by the Adviser to be of comparable quality. The Fund also invests, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities it regards as bonds. A bond is a security or instrument having one or more of the following characteristics: a fixed-income security, a security issued at a discount to its face value, a security that pays interest or a security with a stated principal amount that requires repayment of some or all of that principal amount to the holder of the security. The term “bond” is interpreted broadly by the Adviser as an instrument or security evidencing a promise to pay some amount rather than evidencing the corporate ownership of equity, unless that equity represents an indirect or derivative interest in one or more bonds. Under normal circumstances, the Fund’s portfolio duration is up to three years and the Fund’s dollar-weighted average maturity ranges from one to five years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security to changes in interest rates.

The Fund invests in the U.S. and abroad, including emerging markets, and may purchase securities of varying maturities issued by domestic and foreign corporations and governments.

The Fund may invest up to 25% of its assets in foreign securities that are denominated in U.S. dollars. The Fund may invest up to 15% of its assets in securities of foreign issuers that are not denominated in U.S. dollars. The Fund may invest up to 10% of its assets in emerging market securities.

The Fund’s investments include various types of bonds and debt securities, including corporate bonds, notes, mortgage-related and asset-backed securities (including collateralized debt obligations, which in turn include collateralized bond obligations and collateralized loan obligations), bank loans, U.S. and non-U.S. money market securities, swaps (including credit default swaps), futures, options (including swaptions), municipal securities, defaulted debt securities, private placements and restricted securities. The Fund’s fixed income investments may have interest rates that are fixed, variable or floating.

Derivatives are used in an effort to hedge investments, for risk management, or to increase income or gains for the Fund. The Fund may also seek to obtain market exposure to the securities in which it invests by entering into a series of purchase and sale contracts or by using other investment techniques such as reverse repurchase agreements. The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.

The Fund may normally short sell up to 25% of the value of its total assets.

Investment Objective

The Unconstrained Bond Fund seeks to provide investors with positive long-term returns irrespective of general securities market conditions.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. 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’s operating expenses remain the same. The cost for the Fund reflects the net expenses of the Fund that result from the Class I-3 contractual expense limitation in the first year only (through [ ]). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund 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’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 188% of the average value of its portfolio.

Principal Investment Strategies

The Fund pursues its objective by utilizing a flexible investment approach that allocates investments across a range of global investment opportunities related to credit, currencies and interest rates. Satisfying the Fund’s objective would require it to achieve positive total returns over a full market cycle, i.e., a period of time generally understood to be contained between two consecutive periods of heightened default activity within the global fixed income markets. Total return includes income and capital gains.

The use of the term “unconstrained” in the Fund’s name means that it is not limited by the types of investments in a particular securities index. The Fund is not managed to be compared to any such index. The Fund also is unconstrained in the sense that it is not limited to any single type of investment strategy.

The portfolio management team evaluates each investment idea based on the team’s view of, among other factors, its potential return, its risk level and how it fits within the Fund’s overall portfolio in determining whether to buy or sell investments. The Adviser allocates the Fund’s assets in response to, among other considerations, changing market, financial, economic, and political factors and events that the Fund’s portfolio managers believe may affect the values of the Fund’s investments. The allocation of capital to sectors and securities within each sector in the Fund is driven primarily by the Adviser’s assessment of relative value offered by each sector and security, respectively.

The Adviser seeks to actively manage the Fund’s risks on an on-going basis to mitigate the risks of excessive losses by the portfolio overall. In managing portfolio risk, the Adviser takes into consideration its view of the following factors, among others: the potential relative performance of various market sectors, security selection available within a given sector, the risk/reward equation for different asset classes, liquidity conditions in various market sectors, the shape of the yield curve and projections for changes in the yield curve, potential fluctuations in the overall level of interest rates, and current monetary and fiscal policy.

The Fund invests, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in securities and instruments it regards as bonds in the U.S. and abroad, including emerging markets, and may purchase securities of varying maturities issued by domestic and foreign corporations and governments. A bond is a security or instrument having one or more of the following characteristics: a fixed-income security, a security issued at a discount to its face value, a security that pays interest or a security with a stated principal amount that requires repayment of some or all of that principal amount to the holder of the security. The term “bond” is interpreted broadly by the Adviser as an instrument or security evidencing a promise to pay some amount rather than evidencing the corporate ownership of equity, unless that equity represents an indirect or derivative interest in one or more bonds. The Fund may invest in both investment grade and high yield fixed income securities (commonly known as “junk bonds”), subject to investing no more than 50% of its total assets (measured at the time of investment) in securities rated below investment grade by Moody’s, S&P or Fitch, or, if unrated, determined by the Adviser to be of comparable quality. Under normal circumstances, the average portfolio duration of the fixed-income portion of the Fund’s portfolio will vary from negative three (-3) years to positive eight (8) years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a security to changes in interest rates. As a separate measure, there is no limit on the weighted average maturity of the Fund’s portfolio.

The Fund may invest in foreign securities, and up to 50% of the Fund’s total assets may be invested in emerging markets and instruments that are economically tied to emerging market countries. The Fund considers emerging market countries to include all of the countries in the J.P. Morgan Emerging Market Bond Index (EMBI) Global Diversified, the J.P. Morgan Corporate Emerging Market Bond Index (CEMBI) Broad Diversified, the J.P. Morgan Government Bond Index-Emerging Markets (GBI-EM), the MSCI Emerging Markets Index and the MSCI Frontier Markets Index. Instruments considered to be economically tied to emerging market countries are (i) those that are principally traded in an emerging market country, or (ii) those that are issued by: (a) an issuer organized under the laws of or maintaining a principal place of business in an emerging market country, (b) an issuer that derives or is expected to derive 50% or more of its total revenues, earnings or profits from business activity in an emerging market country, or that maintains or is expected to maintain 50% or more of its employees, assets, investments or operations in an emerging market country, or (c) a governmental or quasi-governmental entity of an emerging market country. The emerging market fixed-income securities in which the Fund may invest are not subject to any minimum credit quality standards, so long as the value of those investments does not cause the Fund to exceed its limit on investments in securities rated below investment grade.

The Fund normally limits its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 40% of its total assets. The Fund reserves the right to hedge its exposure to foreign currencies to reduce the risk of loss from fluctuations in currency exchange rates, but is under no obligation to do so under any circumstances.

The Fund may sell securities and other instruments short provided that not more than 25% of its net assets is held as collateral for those transactions. Derivatives are used in an effort to hedge investments, for risk management or to increase income or gains for the Fund. The types of derivative instruments in which the Fund will principally invest are currency and other futures, forward contracts, options, and swap agreements (typically interest rate swaps, index-linked swaps, total return swaps and credit default swaps). The Fund may invest up to 10% of its total assets in preferred stock and up to 5% in common stock of domestic and foreign companies. The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.

Principal Risks

Because the Fund holds securities with fluctuating market prices, the value of the Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund.

The principal risks affecting the Fund that can cause a decline in value are:

Please see “Principal Risks” and “Other Risks” for a more detailed description of the risks of investing in the Fund.

Your investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, entity, or person.

Performance Information

The following bar chart and table provide some indication of the risks of investing in the Fund. Because Class I-3 has not commenced operations as of the date of this prospectus, the bar chart shows performance for the Fund’s Class M shares and the table shows annual total returns for the Fund’s Class M and Class I shares. Class M and Class I shares would have substantially similar annual returns to Class I-3 shares because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that Class M and Class I shares do not have the same expenses as Class I-3 shares. Performance information for Class I-3 shares will be provided after such shares have one full calendar year of performance.

The bar chart shows changes in the Fund’s performance from year to year. The table compares the average annual total returns of the Fund to a broad-based securities market index and a secondary benchmark index. Total returns would have been lower if certain fees and expenses had not been waived or reimbursed. The inception date of Class M shares and Class I shares of the Fund is September 30, 2011. The inception date for the Plan Class shares is March 6, 2020. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

In some cases, returns after taxes on distributions and sale of Fund shares may be higher than returns before taxes because the calculations assume that the investor received a tax deduction for any loss incurred on the sale of the shares.

Purchase and Sale of Fund Shares

You may purchase or redeem shares of the Funds on any business day (normally any day that the New York Stock Exchange is open). Generally, purchase and redemption orders for shares of the Funds are processed at the net asset value next calculated after an order is received by the Fund. You may conduct transactions by mail (TCW Metropolitan West Funds, c/o BNY Mellon Investment Servicing, P.O. Box 534453, Pittsburgh, PA 15253-4453), or by telephone at (800) 241-4671. You may also purchase or redeem shares of the Funds through your dealer or financial advisor.

Purchase Minimums for Class I-3

The following table provides the minimum initial and subsequent investment requirements for Class I-3. The minimums may be reduced or waived in some cases. A broker-dealer or other financial intermediary may require a higher minimum initial investment, or may aggregate or combine accounts in order to allow its customers to apply a lower minimum investment.

Tax Information

Dividends and capital gains distributions you receive from the Fund are subject to federal income taxes and may also be subject to state and local taxes, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Such tax-deferred arrangements may be taxed later upon withdrawal from those arrangements.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or the Adviser may, directly or through the Fund’s principal underwriter, pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

General

Information about each Fund’s investment objective, principal investment strategies, investment practices and principal risk factors appears in the relevant summary section for each Fund at the beginning of the Prospectus. Each Fund’s investment objective is fundamental and cannot be changed without shareholder approval. The information below describes in greater detail the investments, investment practices and other risks pertinent to the Funds. Some of the Funds may use the investment strategies discussed below more than other Funds.

Principal Investment Strategies

Certain Funds have adopted a policy to invest at least 80% of their net assets, plus any borrowing for investment purposes, in a particular type of security. A Fund may change its 80% policy upon 60 days written notice to shareholders.

Each Fund may engage in defensive investing, which is a deliberate, temporary shift in portfolio strategy that may be undertaken when markets start behaving in volatile or unusual ways. Each Fund may, for temporary defensive purposes, invest a substantial part of its assets in bonds of U.S. or foreign governments, certificates of deposit, bankers’ acceptances, high-grade commercial paper, repurchase agreements, money market funds and cash. When a Fund has invested defensively in low risk, low return securities, it may not achieve its investment objectives. References to minimum credit ratings or quality for securities apply to the time of investment. Downgrades do not require disposition of a holding.

The Funds each invest in a diversified portfolio of fixed-income securities of varying maturities with a different portfolio “duration.” Duration is a measure of the expected life of a fixed-income security that was developed as a more precise alternative to the concept of “term to maturity.” Duration incorporates a bond’s yield, coupon interest payments, final maturity, call and put features and prepayment exposure into one measure. Traditionally, a fixed-income security’s “term to maturity” has been used to determine the sensitivity of the security’s price to changes in interest rates (which is the “interest rate risk” or “volatility” of the security). However, “term to maturity” measures only the time until a fixed-income security provides its final payment, taking no account of the pattern of the security’s payments prior to maturity. Duration is used in the management of the Funds as a tool to measure interest rate risk. For example, a Fund with a portfolio duration of 2 years would be expected to change in value 2% for every 1% move in interest rates. For a more detailed discussion of duration, see “Securities and Techniques used by the Funds — Duration” in the Statement of Additional Information.

High Yield Bond Fund

The Fund invests in a diversified portfolio of high yield fixed-income securities of varying maturities issued by domestic and foreign corporations and governments (and their agencies and instrumentalities) with a portfolio duration of two to eight years under normal circumstances. The meaning of “duration” is explained under “Additional Fund Information — Principal Investment Strategies.” The dollar-weighted average maturity of the Fund’s portfolio ranges from two to fifteen years under normal circumstances. The Fund’s portfolio investments may include corporate bonds, mezzanine investments, swaps (including credit default swaps) and other derivatives (including currency and other futures and options), bank loans, preferred stock, common stock, warrants, mortgage-related and asset-backed securities (including collateralized debt obligations, which in turn include collateralized bond obligations and collateralized loan obligations), foreign securities (including Yankees and emerging markets securities), U.S. Treasuries and agency securities, cash and cash equivalents (such as money-market securities, commercial paper, certificates of deposit and bankers acceptances), private placements, defaulted debt securities and Rule 144A Securities and unrated securities. The Fund’s fixed income investments may have interest rates that are fixed, variable or floating.

The Adviser focuses the Fund’s portfolio holdings in areas of the bond market that the Adviser believes to be relatively undervalued, based on its analysis of quality, sector, coupon or maturity, and that the Adviser believes offer attractive prospective risk-adjusted returns compared to other segments of the bond market. Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in a portfolio of high yield securities (commonly known as “junk bonds”), which are bonds rated below investment grade by at least one of the nationally recognized statistical rating organizations (i.e., debt securities rated below Baa3 by Moody’s, BBB- by S&P or BBB- by Fitch, or A2 by S&P, P-2 by Moody’s or F-2 by Fitch for short-term debt obligations), or unrated securities determined by the Adviser to be of comparable quality. The remainder of the Fund’s net assets may be invested in investment grade securities rated by one of the nationally recognized statistical rating organizations or, if unrated, of comparable quality in the opinion of the Adviser.

The Fund may invest up to 25% of its assets in foreign securities that are denominated in U.S. dollars. The Fund may invest up to 15% of its assets in securities of foreign issuers that are not denominated in U.S. dollars. The Fund may invest up to 10% of its assets in emerging market securities. The Fund may invest in securities issued by entities in any country or region. The Fund reserves the right to hedge its exposure to foreign currencies to reduce the risk of loss due to fluctuations in currency exchange rates, but normally does not do so.

The Fund may invest in futures and options and may invest up to 15% of its total assets in premiums and margins on derivative instruments such as futures and options. The Fund may borrow from banks and or other financial institutions or through reverse repurchase agreements. The Fund may also seek to obtain similar or alternative market exposure to the securities in which it directly invests by instead using other investment techniques such as derivatives, repurchase agreements, reverse repurchase agreements, and dollar rolls. Please see “Securities and Techniques Used by the Funds” in the Statement of Additional Information for additional information regarding those investment types.

The Fund may normally borrow or short sell up to 33 1/3% of the value of its total assets. The Adviser normally sells debt or equity securities “short” that the Adviser believes will underperform comparable securities, drawing on analyses of earnings, timing, pricing, or other factors.

Low Duration Bond Fund

The Fund invests in a diversified portfolio of fixed-income securities of varying maturities issued by domestic and foreign corporations and governments (and their agencies and instrumentalities) with a portfolio duration of up to three years under normal circumstances. The meaning of “duration” is explained under “Additional Fund Information — Principal Investment Strategies.” The dollar-weighted average maturity of the Fund’s portfolio ranges from one to five years under normal circumstances. The Fund’s portfolio investments may include bonds, notes, mortgage-related and asset-backed securities (including collateralized debt obligations, which in turn include collateralized bond obligations and collateralized loan obligations), bank loans, U.S. and non-U.S. money market securities, municipal securities, swaps (including credit default swaps) and other derivatives (including futures, options and swaptions), private placements, defaulted debt securities and Rule 144A Securities. The Fund’s fixed income investments may have interest rates that are fixed, variable or floating.

Under normal circumstances, the Fund invests at least 70% of its net assets in highly rated fixed income securities (i.e., debt securities rated at least A by Moody’s, S&P or Fitch, or A-2 by S&P, P-2 by Moody’s or F-2 by Fitch for short-term debt obligations), or unrated securities determined by the Adviser to be of comparable quality. Up to 30% of the Fund’s net assets may be invested in securities rated below highly rated securities by all three of the nationally recognized statistical rating organizations or unrated securities determined by the Adviser to be of comparable quality. Of that amount, not more than 20% of the Fund’s net assets may be invested in securities rated below investment grade (i.e., debt securities rated below Baa3 by Moody’s, BBB- by S&P or BBB- by Fitch, or A2 by S&P, P-2 by Moody’s or F-2 by Fitch for short-term debt obligations) or unrated securities determined by the Adviser to be of comparable quality. The Fund also invests, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities it regards as bonds.

The Fund may invest up to 25% of its assets in foreign securities that are denominated in U.S. dollars. The Fund may invest up to 15% of its assets in securities of foreign issuers that are not denominated in U.S. dollars. The Fund may invest up to 10% of its assets in emerging market securities. The Fund may invest in securities issued by entities in any country or region. The Fund reserves the right to hedge its exposure to foreign currencies to reduce the risk of loss due to fluctuations in currency exchange rates, but normally does not do so. The Fund may invest in futures and options and may invest up to 15% of its total assets in premiums and margins on derivative instruments such as futures and options. The Fund may borrow from banks and or other financial institutions or through reverse repurchase agreements. The Fund may also seek to obtain similar or alternative market exposure to the securities in which it directly invests by instead using other investment techniques such as derivatives, repurchase agreements, reverse repurchase agreements, and dollar rolls. Please see “Securities and Techniques Used by the Funds” in the Statement of Additional Information for additional information regarding those investment types.

The Fund may normally short sell up to 25% of the value of its total assets. The Adviser normally sells debt or equity securities “short” that the Adviser believes will underperform comparable securities, drawing on analyses of earnings, timing, pricing, or other factors.

Total Return Bond Fund

The Fund invests in a diversified portfolio of fixed-income securities of varying maturities issued by domestic and foreign corporations and governments (and their agencies and instrumentalities) with a portfolio duration of two to eight years under normal circumstances. The meaning of “duration” is explained under “Additional Fund Information — Principal Investment Strategies.” The dollar-weighted average maturity of the Fund’s portfolio ranges from two to fifteen years. The Fund’s portfolio investments may include bonds, notes, mortgage-related and asset-backed securities (including collateralized debt obligations, which in turn include collateralized bond obligations and collateralized loan obligations), bank loans, U.S. and non-U.S. money market securities, municipal securities, swaps (including credit default swaps) and other derivatives (including futures, options and forward contracts), private placements, defaulted debt securities and Rule 144A Securities. The Fund’s fixed income investments may have interest rates that are fixed, variable or floating.

The Adviser focuses the Fund’s portfolio holdings in areas of the bond market that the Adviser believes to be relatively undervalued, based on its analysis of quality, sector, coupon or maturity, and that the Adviser believes offer attractive prospective risk-adjusted returns compared to other segments of the bond market.

Under normal circumstances, the Fund invests at least 80% of its net assets in investment grade securities (i.e., debt securities rated at least Baa3 by Moody’s, BBB- by S&P or BBB- by Fitch, or A-2 by S&P, P-2 by Moody’s or F-2 by Fitch for short-term debt obligations, or unrated securities determined by the Adviser to be of comparable quality). Up to 20% of the Fund’s net assets may be invested in securities rated below investment grade or unrated securities determined by the Adviser to be of comparable quality. The Fund also invests, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities it regards as bonds.

The Fund may invest up to 25% of its assets in foreign securities that are denominated in U.S. dollars. The Fund may invest up to 15% of its assets in securities of foreign issuers that are not denominated in U.S. dollars. The Fund may invest up to 10% of its assets in emerging market securities. The Fund may invest in securities issued by entities in any country or region. The Fund reserves the right to hedge its exposure to foreign currencies to reduce the risk of loss due to fluctuations in currency exchange rates, but normally does not do so.

The Fund may invest in futures and options and may invest up to 15% of its total assets in premiums and margins on derivative instruments such as futures and options. The Fund may borrow from banks and or other financial institutions or through reverse repurchase agreements. The Fund may also seek to obtain similar or alternative market exposure to the securities in which it directly invests by instead using other investment techniques such as derivatives, repurchase agreements, reverse repurchase agreements, and dollar rolls. Please see “Securities and Techniques Used by the Funds” in the Statement of Additional Information for additional information regarding those investment types.

The Fund may normally short sell up to 25% of the value of its total assets. The Adviser normally sells debt or equity securities “short” that the Adviser believes will underperform comparable securities, drawing on analyses of earnings, timing, pricing, or other factors.

Unconstrained Bond Fund

In addition to the investment techniques and types of investments described in the summary section of this prospectus, the Fund may also pursue its investment objective as described below. Because this Fund is not constrained by the characteristics or performance of any particular securities index or by any specific investment strategy, there can be no assurances as to which types of investments or strategies will be emphasized at any particular time.

The Fund employs an absolute return type of investment approach. This means that the Fund typically compares its performance against short-term cash instruments, adjusting to compensate for the amount of investment risk assumed. Relative return strategies, by contrast, seek to outperform a designated stock, bond or other market index, and measure their performance primarily in relation to that type of benchmark index. The intent is that, over time, the investment performance of absolute return strategies typically should be substantially independent of longer term movements in the stock and bond market. In making investment decisions on behalf of the Fund, the Adviser uses a variety of techniques such as a fundamental asset valuation model, quantitative portfolio optimization and risk management techniques. The Adviser seeks to invest in sectors of the markets that it believes offer the best risk adjusted returns and to manage the targeted volatility of the Fund. Certain investment techniques such as buying/selling options and futures, swaps and other derivatives may also be employed in an effort to reduce the Fund’s volatility.

The Fund invests, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in securities and instruments it regards as bonds in the U.S. and abroad, including emerging markets, and may

purchase securities of varying maturities issued by domestic and foreign corporations and governments. A “bond” as used in the name of the Fund is a security or instrument having one or more of the following characteristics: a fixed-income security, a security issued at a discount to its face value, a security that pays interest or a security with a stated principal amount that requires repayment of some or all of that principal amount to the holder of the security. The term bond is interpreted broadly by the Adviser as an instrument or security evidencing a promise to pay some amount rather than evidencing the corporate ownership of equity, unless that equity represents an indirect or derivative interest in one or more bonds. Bonds for this purpose also include instruments that are intended to provide one or more of the characteristics of a direct investment in one or more bonds.

The Fund may invest up to 50% of its total assets (measured at the time of investment) in securities rated below investment grade by Moody’s, S&P or Fitch or unrated securities determined by the Adviser to be of comparable quality.

The Fund may use certain types of investments and investing techniques that are described in more detail in the Statement of Additional Information.

The Fund may invest in securities of foreign issuers. The Fund’s foreign currency exposure (from investments in securities of foreign issuers that are not denominated in U.S. dollars) is normally limited to a maximum of 40% of the Fund’s total assets. The Fund may invest up to 50% of its total assets in emerging market securities. The Fund may invest in securities issued by entities in any country or region. The emerging market fixed income securities in which the Fund may invest are not subject to any minimum credit quality standards, so long as the value of those investments does not cause the Fund to exceed its limit on investments in securities rated below investment grade.

The Fund may sell securities and other instruments short provided that not more than 25% of its net assets is held as collateral for those transactions. The Adviser normally sells debt or equity securities “short” that the Adviser believes will underperform comparable securities, drawing on analyses of earnings, timing, pricing, or other factors.

The Fund invests in a diversified portfolio of fixed-income securities of varying maturities issued by domestic and foreign corporations and governments (and their agencies and instrumentalities) with the average portfolio duration of the fixed-income portion of the Fund’s portfolio varying from negative three (-3) years to positive eight (8) years under normal circumstances. The meaning of “duration” is explained under “Additional Fund Information — Principal Investment Strategies.” There is no limit on the weighted average maturity of the Fund’s portfolio.

The Fund may enter into various types of swap agreements as noted previously. These can include, for example, credit default, interest rate, total return, index and currency exchange rate swap agreements. These transactions attempt to obtain a particular return when it is considered desirable to do so, possibly at a lower cost to a Fund than if the Fund had invested directly in an instrument that yielded that desired return. Swap agreements are two-party contracts entered into primarily by institutional investors, where there is any agreement to exchange the returns on particular investments.

Whether a Fund’s use of swap agreements will be successful in furthering its investment objectives will depend on the Adviser’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Credit default swaps involve parties effectively buying or selling protection with respect to whether an event of default by a selected entity (or entities) will occur. Interest rate swaps involve the exchange of interest payments by the Fund with another party, such as an exchange of floating rate payments for fixed interest rate payments. A total return swap is the generic name for any swap where one party agrees to pay the other the “total return” of a defined underlying asset, usually in return for receiving a stream of cash flows. Total return swaps are most commonly used with equity indices, single stocks, bonds and defined portfolios of loans and mortgages.

Asset-Backed Securities Risk

Asset-backed securities are bonds or notes backed by a discrete pool of financial assets such as credit card receivables, automobile receivables and student loans. The impairment of the value of the financial assets underlying an asset-backed security, such as the non-payment of loans, may result in a reduction in the value of such asset-backed security. Certain asset-backed securities do not have the benefit of the same security interest in the underlying financial assets as do mortgage-backed securities, nor are they provided government guarantees of repayment. Accordingly, issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the asset-backed securities, if any, may be inadequate to protect investors in the event of default. For example, credit card receivables are generally unsecured, and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. In addition, some issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. Asset-backed securities are also subject to prepayment risk in a declining interest rate environment and extension risk in a rising interest rate environment.

Certain Funds may invest in collateralized debt obligations (“CDOs”), which are debt instruments backed solely by a pool of other debt securities. CDOs include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust typically collateralized by a diversified pool of high-risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, and may include loans that are rated below investment grade or equivalent unrated loans. CDOs may charge management fees and administrative expenses.

The risks of an investment in a CBO, CLO, or other CDO depend largely on the type of the collateral securities (which would have the risks described elsewhere in this Prospectus for that type of security) and the class of the CBO, CLO or other CDO in which a Fund invests. Some CBOs, CLOs and other CDOs have credit ratings, but are typically issued in various classes with various priorities. Normally, CBOs, CLOs and other CDOs are privately offered and sold (that is, not registered under the federal securities laws) and may be characterized by a Fund as illiquid securities, but an active dealer market may exist for CBOs, CLOs and other CDOs that qualify for Rule 144A transactions. In addition to the normal interest rate, default and other risks of fixed income securities discussed elsewhere in this Prospectus, CBOs, CLOs and other CDOs carry additional risks, including the possibility that distributions from collateral securities will not be adequate to make interest or other payments, the collateral may decline in value or default, a Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes, volatility in values, and the complex structure of the security may not be fully understood at the time of investment, which may result in disputes with the issuer or produce unexpected investment results.

Bank Loan Risk

Commercial banks and other financial institutions or institutional investors make corporate loans to companies that need capital to grow or restructure. There are a number of risks associated with an investment in bank loans, including credit risk, interest rate risk, liquidity risk and prepayment risk. Lack of an active trading market, restrictions on resale, irregular trading activity, wide bid/ask spreads and extended trade settlement periods (i.e., longer than seven (7) days) may impair a Fund’s ability to sell bank loans within its desired time frame or at an acceptable price and its ability to accurately value existing and prospective investments. Extended trade settlement periods may result in cash not being immediately available to a Fund. As a result, a Fund may have to sell other investments or engage in borrowing transactions to raise cash to meet its obligations. The risk of holding bank loans is also directly tied to the risk of insolvency or bankruptcy of the issuing banks. If a Fund holds a bank loan through another financial institution, or relies on a financial institution to

administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. It is possible that any collateral securing a bank loan may be insufficient or unavailable to a Fund, and that a Fund’s rights to collateral may be limited by bankruptcy or insolvency laws. There may be limited public information available regarding a bank loan. These risks could cause a Fund to lose income or principal on a particular investment, which in turn could affect the Fund’s returns. The value of bank loans can be affected by and sensitive to changes in government regulation and to economic downturns in the U.S. and abroad. Borrowers generally pay interest on bank loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (SOFR) or the prime rates of U.S. banks. As a result, the value of bank 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. Bank loans are not registered and otherwise may not be treated as securities under the federal securities laws, meaning investors in loans have less protection against improper practices than investors in securities that are registered under or are otherwise subject to the protections of the securities laws.

Below Investment Grade Mortgage-Backed Securities Risk

The Funds may invest in residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”) that are rated below investment grade or, if unrated, determined by the Adviser to be of comparable quality. RMBS and CMBS rated below investment grade generally carry greater liquidity risk than their investment grade counterparts. Historically, the market for these securities, and for below investment grade asset-backed securities in general, has been characterized at times by less liquidity than the market for comparable investment grade securities, particularly during the financial crisis of 2007 and 2008. In the aftermath of that period, the market for such securities has improved and become more transparent, but the asset class remains complicated.

The Adviser has extensive experience analyzing, managing and trading below investment grade RMBS and CMBS. A below investment grade RMBS or CMBS may be classified as liquid only if the Adviser reasonably expects that the below investment grade RMBS or CMBS can be disposed of in current market conditions within seven (7) calendar days without the sale or disposition significantly changing the market value of the RMBS or CMBS, based on a number of factors including, but not limited to, bid and ask spreads, frequency of trades or quotes, number of dealers willing to purchase or sell the security, rating history of the security, whether there are contractual penalties for unwinding a purchase or contractual restrictions on trading, and other factors relating to the trading history of the security and corporate events of the issuer (such as bankruptcy or reorganization). The Adviser also conducts ongoing evaluations of the below investment grade RMBS and CMBS held by a Fund, including extensive risk management processes with respect to the liquidity of those investments.

While the Adviser generally intends to invest in markets that are liquid, depending on market conditions, market liquidity for lower-rated investments may be more likely to deteriorate than for higher-rated investments. Dealers in below investment grade mortgage-backed securities play an important role in providing liquidity, but are under no obligation to do so and may stop providing liquidity at any time. The impact of recent regulatory changes may further limit the ability or willingness of dealers to provide liquidity. Changing regulatory and market conditions, especially conditions in the housing market or changes to the status of the issuers of these securities, may adversely affect the liquidity of a Fund’s investments. These risks may be magnified in a rising interest rate environment or in other circumstances where investor redemptions from fixed income mutual funds may be higher than normal, causing increased supply in the market due to selling activity.

Counterparty Risk

Counterparty risk refers to the risk that the other party to a contract, such as individually negotiated or over-the-counter derivatives (e.g., swap agreements that are not centrally cleared and participations in loan obligations), will not fulfill its contractual obligations, which may cause losses or additional costs to a Fund or cause a Fund to experience delays in recovering its assets.

Credit Risk

Credit risk refers to the risk that an issuer may default in the payment of principal and/or interest on a security. Financial strength and solvency of an issuer are the primary factors influencing credit risk. In addition, lack of or inadequacy of collateral or credit enhancements for a fixed income security may affect its credit risk. Credit risk of a security may change over time, and securities which are rated by ratings agencies are often reviewed and may be subject to downgrade. However, ratings are only opinions of the agencies issuing them and are not absolute guarantees as to quality.

Debt Securities Risk

Debt securities are subject to various risks. Debt securities are subject to two primary (but not exclusive) types of risk: credit risk and interest rate risk. These risks can affect a debt security’s price volatility to varying degrees, depending upon the nature of the instrument. Other factors, such as market fluctuations and the depth and liquidity of the market for an individual or class of debt security, can also affect the value of a debt security and, hence, the market value of a Fund.

Derivatives Risk

The Funds may invest in derivatives, which are financial instruments whose performance is derived, at least in part, from the performance of an underlying instrument, such as a currency, security, commodity, interest rate or index. The Funds invest in futures, options and swaps, but may use other types of financial derivatives. The various derivative instruments that the Funds may use are described in more detail here and under “Derivative Instruments” in the Statement of Additional Information. The Funds typically use derivatives as a substitute for directly investing in an underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or currency risk. The Funds also may use derivatives for leverage, in which case their use would involve leverage risk.

The Funds’ use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to a number of risks described elsewhere in this section, such as liquidity risk, interest rate risk, market risk, credit risk and management risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. If a Fund invests in a derivative instrument it could lose more than the principal amount invested. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that a Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial.

The Funds’ participation in the options or futures markets, as well as the use of various swap instruments, involves investment risks and transaction costs to which a Fund would not be subject absent the use of these strategies. If the Adviser’s predictions of movements in the direction of the securities and interest rate markets are inaccurate, the adverse consequences to a Fund may leave the Fund in a worse position than if such strategies were not used. Risks inherent in the use of options, futures contracts and options on futures contracts include: (i) dependence on the Adviser’s ability to predict correctly movements in the direction of interest rates and securities prices; (ii) imperfect correlation between the price of options and futures contracts and options thereon and movements in the prices of the securities being hedged; (iii) the fact that skills needed to use these strategies are different from those needed to select portfolio securities; (iv) the absence of a liquid secondary market for any particular instrument at any time; (v) the possible need to defer closing out certain hedged positions to avoid adverse tax consequences; and (vi) the possible inability of a Fund to purchase or sell a portfolio security at a time that otherwise would be favorable for it to do so, or the possible need for a Fund to sell the security at a disadvantageous time. A Fund could lose the entire amount it invests in futures and other derivatives. The loss from investing in certain derivatives is potentially unlimited. There also is no assurance that a liquid secondary market will exist for futures contracts and options in which a Fund may invest. Each Fund limits its investments in futures contracts so that the notional value (meaning the stated contract value) of the futures contracts does not exceed the net assets of that Fund.

Rule 18f-4 under the 1940 Act (the “Derivatives Rule”), adopted by the SEC on October 28, 2020, replaces previous asset segregation requirements with a new framework for the use of derivatives by registered funds. For funds using a significant amount of derivatives, the Derivatives Rule mandates a fund adopt and/or implement: (i) value at risk limitations in lieu of asset segregation requirements; (ii) a written derivatives risk management program; (iii) new board oversight responsibilities; and (iv) new reporting and recordkeeping requirements. The Derivatives Rule provides an exception for funds with derivative exposure not exceeding 10% of its net assets, excluding certain currency and interest rate hedging transactions. In addition, the Derivatives Rule provides special treatment for reverse repurchase agreements and similar financing transactions and unfunded commitment agreements.

In addition, derivatives, such as swaps, forward contracts and non-deliverable forward contracts, are subject to regulation under the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and other laws or regulations in Europe and other foreign jurisdictions. Under the Dodd-Frank Act, certain derivatives have become subject to new and increased margin requirements, which in some cases has increased the costs to the Funds of trading derivatives and may reduce returns to shareholders in the Funds.

Distressed and Defaulted Securities Risk

A security held by a Fund may default, or the issuer of a security held by a Fund may become distressed, after the Fund’s investment. The High Yield Bond Fund, Low Duration Bond Fund, Total Return Bond Fund, and Unconstrained Bond Fund may invest a significant portion of their assets in fixed income securities that are distressed or defaulted at the time of investment. Repayment of defaulted securities and obligations of distressed issuers (including insolvent issuers or issuers in payment or covenant default, in workout or restructuring or in bankruptcy or solvency proceedings) is subject to significant uncertainties. A Fund will generally not receive interest payments on distressed or defaulted securities and may incur costs to protect its investment. In addition, distressed or defaulted securities involve the substantial risk that principal will not be repaid. A 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. Therefore, to the extent that a Fund is invested in distressed securities, its ability to achieve current income for its shareholders may be diminished. A Fund also is subject to significant uncertainty as to when, in what manner and for what value the obligations evidenced by the distressed securities will eventually be satisfied. In any reorganization or liquidation proceeding relating to a portfolio company, a Fund may lose its entire investment or may be required to accept cash or securities with a lower value or income potential than its original investment. Distressed or defaulted securities and any securities received in an exchange for such securities may be illiquid and subject to restrictions on resale, such that the Fund may the Fund may be restricted from disposing of those securities. Investments in defaulted securities and obligations of distressed issuers are considered speculative.

Emerging Markets Risk

The risks described under “Principal Risks — Foreign Investing Risk” also apply to emerging market securities, and the risks of investing in emerging market countries tend to be greater as compared to the risks of investing in more developed countries.

Investing in emerging and developing market countries involves substantial risk due to, among other factors, higher brokerage costs in certain countries; different accounting standards; thinner trading markets as compared to those in developed countries; the possibility of currency transfer restrictions; and the risk of expropriation, nationalization or other adverse political, economic or social developments. There may be less publicly available information about issuers in emerging markets than is available about issuers in more developed capital markets.

Political and economic structures in some emerging and developing market countries may be undergoing significant evolution and rapid development, and such countries may lack the social, political and economic stability characteristics of developed countries. Some of these countries have in the past failed to recognize private property rights and have at times nationalized or expropriated the assets of private companies. Such social, political and economic instability could disrupt the financial markets in which the Funds invest and adversely affect the value of their investment portfolios.

The securities markets of emerging and developing market countries can be substantially smaller, less developed, less liquid and more volatile than the major securities markets in the U.S. and other developed nations. The limited size of many securities markets in emerging and developing market countries and limited trading volume in issuers compared to the volume in U.S. securities or securities of issuers in other developed countries could cause prices to be erratic for reasons other than factors that affect the quality of the securities. For example, limited market size may cause prices to be unduly influenced by traders who control large positions. Adverse publicity and investors’ perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of portfolio securities, especially in these markets.

Securities markets in emerging markets may also be susceptible to manipulation or other fraudulent trade practices, which could disrupt the functioning of these markets or adversely affect the value of investments traded in these markets, including investments of the Funds. A Fund’s rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the Funds to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, emerging and developing market countries’ exchanges and broker-dealers are generally subject to less government and exchange regulation than their counterparts in developed countries. Brokerage commissions, dealer concessions, custodial expenses and other transaction costs are generally higher in emerging and developing market countries than in developed countries. As a result, funds that invest in emerging and developing market countries generally have operating expenses that are higher than funds investing in more established market regions.

Some emerging and developing market countries have a greater degree of economic, political and social instability than the U.S. and other developed countries. Such social, political and economic instability could disrupt the financial markets in which the Funds invest and adversely affect the value of their investment portfolios. Economies in emerging and

developing market countries may also be more susceptible to natural and man-made disasters, such as earthquakes, tsunamis, terrorist attacks, or adverse changes in climate or weather. In addition, many emerging and developing market countries with less established health care systems have experienced outbreaks of pandemic or contagious diseases from time to time, including, but not limited to, coronavirus, Ebola, Zika, avian flu, severe acute respiratory syndrome, and Middle East Respiratory Syndrome. The risks of such phenomena and resulting social, political, economic and environmental damage cannot be quantified. These events can exacerbate market volatility as well as impair economic activity, which can have both short- and immediate-term effects on the valuations of the companies and issuers in which the Funds invest. Risks associated political changes or diplomatic developments can negatively impact the securities markets and cause a Fund to lose value.

Currencies of emerging and developing market countries experience devaluations relative to the U.S. dollar from time to time. A devaluation of the currency in which investment portfolio securities are denominated will negatively impact the value of those securities in U.S. dollar terms. Emerging and developing market countries have and may in the future impose foreign currency controls and repatriation controls.

Among other risks of investing in emerging and developing market countries are the variable quality and reliability of financial information and related audits of companies. In some cases, financial information and related audits can be unreliable and not subject to verification. Auditing firms in some of these markets are not subject to independent inspection or oversight of audit quality. This can result in investment decisions being made based on flawed or misleading information. Additionally, investors may have substantial difficulties in bringing legal actions to enforce or protect investors’ rights, which can increase the risks of loss.

Any of these factors may adversely affect a Fund’s performance or a Fund’s ability to pursue its investment objective.

Equity Risk

Equity securities may include common stock, preferred stock or other securities representing an ownership interest or the right to acquire an ownership interest in an issuer. Equity risk is the risk that stocks and other equity securities generally fluctuate in value more than bonds and may decline in value over short or extended periods. The value of stocks and other equity securities may be affected by changes in an issuer’s financial condition, factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry, or as a result of changes in overall market, economic and political conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

Preferred Securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities may pay fixed or adjustable rates of return. In addition, a company’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’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

Extension Risk

Extension risk is the risk that in times of rising interest rates, borrowers may pay off their debt obligations more slowly, causing securities considered short- or intermediate-term to become longer-term securities that fluctuate more widely in response to changes in interest rates than shorter-term securities. This may cause the market value of such securities to decline and will also delay the Fund’s ability to reinvest proceeds at higher interest rates. Extension risk applies primarily to mortgage-related and other asset-backed securities.

Foreign Currency Risk

Funds that invest in foreign (non-U.S.) currencies or in foreign securities that are denominated, trade and/or receive revenues in foreign (non-U.S.) currencies are subject to the risk that those foreign currencies may decline in value relative to the U.S. dollar. In the case of currency hedging positions, a Fund is subject to the risk that the U.S. dollar may decline in value relative to the currency being hedged. Currency exchange rates may fluctuate significantly and unpredictably. As a result, a Fund’s investments in foreign currencies, in foreign securities that are denominated, trade, and/or receive revenues in foreign currencies, or in derivatives that provide exposure to foreign currencies may reduce the returns of the Funds.

Foreign Investing Risk

Investments in foreign securities may involve greater risks than investing in U.S. securities.

As compared to U.S. companies, foreign issuers generally disclose less financial and other information publicly and are subject to less stringent and less uniform accounting, auditing and financial reporting standards. Foreign countries typically impose less thorough regulations on brokers, dealers, stock exchanges, corporate insiders and listed companies than does the U.S., and foreign securities markets may be less liquid and more volatile than U.S. markets. Investments in foreign securities generally involve higher costs than investments in U.S. securities, including higher transaction and custody costs as well as additional taxes imposed by foreign governments. In addition, security trading practices abroad may offer less protection to investors such as the Funds. U.S. regulators may be unable to enforce a company’s regulatory obligations. Political or social instability, civil unrest, acts of terrorism, regional economic volatility, and the imposition of sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and/or other governments are other potential risks that could impact an investment in a foreign security. As one current example, the war in Ukraine has led to sanctions being levied against Russia by the United States, European Union (the “EU”) and other countries, which has adversely affected European and global energy and financial markets and thus could affect the value of a Fund’s investments. Settlement of transactions in some foreign markets may be delayed or may be less frequent than in the U.S., which could affect the liquidity of a Fund’s portfolio. In addition, European financial markets have in recent years experienced increased volatility due to concerns with some countries’ high levels of sovereign debt, budget deficits and unemployment. Markets have also been affected by the withdrawal of the United Kingdom (the “UK”) from the EU on January 31, 2020 (an event commonly known as “Brexit”). There remains uncertainty surrounding the ultimate impact of Brexit on the UK, the EU and the broader global economy. An exit by any member countries from the EU or the Economic and Monetary Union of the EU, or even the prospect of such an exit, could lead to increased volatility in European markets and negatively affect investments both in issuers in the exiting country and throughout Europe. Whether or not a Fund invests in securities of issuers located in Europe or with significant exposure to European issuers or countries, these events could negatively affect the value and liquidity of the Fund’s investments due to the interconnected nature of the global economy and capital markets.

Secessionist movements, such as the Catalan movement in Spain and the independence movement in Scotland, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. In addition, the national politics of countries in the EU have been unpredictable and subject to influence by disruptive political groups and ideologies. The governments of EU countries may be subject to change and such countries may experience social and political unrest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe could also impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Funds’ investments.

Frequent Trading Risk

Frequent trading of portfolio securities may produce capital gains, which are taxable to shareholders when distributed. As a result, frequent trading may cause higher levels of current tax liability to shareholders in a Fund. Frequent trading will lead to increased portfolio turnover and increase the total amount of commissions or mark-ups to broker-dealers that a Fund pays when it buys and sells securities, which may reduce the Fund’s performance.

Futures Contracts Risk

Investing in futures contracts involves various risks, including (1) the imperfect correlation between a futures contract and the change in market value of the underlying instrument held by the Fund; (2) a high degree of leverage because of the low collateral deposits normally involved in futures trading; (3) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (4) losses caused by unanticipated market movements, which are potentially unlimited; and (5) the inability of the Fund to execute a trade because of the maximum permissible price movements exchanges may impose on futures contracts.

Inflation Risk

Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of a Fund’s assets and distributions may decline. Inflation creates uncertainty over the future real value (after inflation) of an investment. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy, and a Fund’s investments may not keep pace with inflation, which may result in losses to Fund investors.

Interest Rate Risk

Interest rate risk is the potential for a decline in bond prices due to rising interest rates. In general, bond prices vary inversely with interest rates. The change in a bond’s price depends on several factors, including the bond’s maturity date. The degree to which a bond’s price will change as a result of changes in interest rates is measured by its “duration.” For example, the price of a bond with a 5-year duration would be expected under normal market conditions to decrease 5% for every 1% increase in interest rates. Generally, bonds with longer maturities have a greater duration and thus are subject to greater price volatility from changes in interest rates. Adjustable rate instruments also react to interest rate changes in a similar manner although generally to a lesser degree (depending, however, on the characteristics of the reset terms, including the index chosen, frequency of reset and reset caps or floors, among other things). It is possible that there will be less governmental action in the future to maintain low interest rates. The negative impact on fixed income securities from interest rate increases, regardless of the cause, could be swift and significant, which could result in significant losses by the Funds, even if anticipated by the Adviser.

Risks associated with rising interest rates are heightened given that the U.S. Federal Reserve Board (the “Fed”) has sharply raised interest rates in recent years, and they remain at their highest levels in over twenty years. Other central banks globally have implemented similar rate increases. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary policies, inflation rates, or general economic conditions).

Changing interest rates may have unpredictable effects on fixed income and related markets, may result in heightened market volatility and may detract from Fund performance to the extent that the Fund is exposed to interest rates. During periods of low interest rates, a Fund may be unable to maintain positive returns. Increases in interest rates may reduce liquidity for certain Fund investments, which could cause the value of a Fund’s investments and share price to decline. Interest rate increases may also lead to heightened Fund redemption activity, which may cause a Fund to lose value as a result of the costs that it incurs in turning over its portfolio and may lower its performance. A Fund that invests in derivatives tied to fixed income markets may be more substantially exposed to these risks than a Fund that does not invest in those derivatives.

Issuer Risk

The value of securities held by a Fund may decline for a number of reasons directly related to an issuer, such as changes in the financial condition of the issuer, management performance, financial leverage and reduced demand for the issuer’s goods or services. The amount of dividends paid with respect to equity securities, or the ability of an issuer to make payments in connection with debt securities, may decline for reasons that relate to the issuer, such as changes in an issuer’s financial condition or a decision by the issuer to pay a lower dividend, or for reasons that relate to the broader financial system. In addition, there may be limited public information available for the Adviser to evaluate foreign issuers.

Junk Bond Risk

Debt securities that are rated below investment grade are commonly known as high yield securities or “junk bonds.” Junk bonds (including low-rated and comparable unrated securities), while generally offering higher yields than investment grade securities with similar maturities, involve greater risks, including the possibility of default or bankruptcy. Junk bonds are regarded as speculative with respect to an issuer’s capacity to pay interest and to repay principal. They are usually issued by companies without long track records of sales and earnings, or by companies with questionable credit strength. They may also be issued by highly leveraged companies, which may be less able to meet their contractual obligations than a less leveraged company. These bonds have a higher degree of default risk and may be less liquid than higher-rated bonds. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, and negative perceptions of junk bonds generally. In addition, junk bonds tend to be less marketable than higher-quality debt securities because the market for them is not as broad or active. The potential lack of a liquid secondary market may have an adverse effect on the market price of, and a Fund’s ability to sell, particular securities, and may make it more difficult for the Adviser to accurately value certain high yield securities held by a Fund.

Leverage Risk

Leverage created from certain types of transactions or instruments, such as borrowing, engaging in reverse repurchase agreements, entering into futures contracts or forward currency contracts, engaging in forward commitment transactions and investing in leveraged or unleveraged commodity index-linked notes, may impair a Fund’s liquidity, cause it to liquidate positions at an unfavorable time, increase its volatility or otherwise cause it not to achieve its intended result. During periods of adverse market conditions, the use of leverage may cause a Fund to lose more money than would have been the case if leverage was not used. To the extent required by applicable law or regulation, the Funds will reduce leverage risk by either segregating an equal amount of liquid assets or “covering” the transactions that introduce such risk.

Liquidity Risk

A Fund’s investments in illiquid securities may reduce the returns of the Fund because it may not be able to sell the illiquid securities at an advantageous time or price. Investments in high yield securities, foreign securities, derivatives or other securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Certain investments in private placements and Rule 144A Securities may be considered illiquid investments.

Furthermore, reduced number and capacity of dealers and other counterparties to “make markets” in fixed income securities, in connection with the growth of the fixed income markets, may increase liquidity risk with respect to a Fund’s investments in fixed income securities. When there is no willing buyer and investments cannot be readily sold, a Fund may have to sell them at a lower price or may not be able to sell the securities at all, each of which would have a negative effect on the Fund’s performance. These securities may also be difficult to value and their values may be more volatile because of liquidity risk. Increased Fund redemption activity, which may occur in a rising interest rate environment or for other reasons, may negatively impact Fund performance and increase liquidity risk due to the need of the Fund to sell portfolio securities. Regulations such as the Volcker Rule or future regulations may further constrain the ability of market participants to create liquidity, particularly in times of increased market volatility. The liquidity of a Fund’s assets may change over time.

Below investment grade mortgage-backed securities are subject to additional liquidity risks, which are discussed above under “Principal Risks — Below Investment Grade Mortgage-Backed Securities.”

Market Risk

Various market risks can affect the price or liquidity of an issuer’s securities in which a Fund may invest. Returns from the securities in which a Fund invests may underperform returns from the various general securities markets or different asset classes. Different types of securities tend to go through cycles of outperformance and underperformance in comparison to the general securities markets. Adverse events occurring with respect to an issuer’s performance or financial position can depress the value of the issuer’s securities. The liquidity in a market for a particular security will affect its value and may be affected by factors relating to the issuer, as well as the depth of the market for that security. Other market risks that can affect value include a market’s current attitudes about types of securities, market reactions to political or economic events, including litigation, and tax and regulatory effects (including lack of adequate regulations for a market or particular type of instrument). In addition, recent failures in the banking sector have caused significant disruption and volatility in U.S. and global markets.

Federal, state, and other governments, their regulatory agencies, or self-regulatory organizations may take actions that affect the regulation of the securities in which a Fund invests or the issuers of such securities in ways that are unforeseeable. Legislation or regulation may also change the way in which the Funds are regulated. Such legislation or regulation could limit or preclude a Fund’s ability to achieve its investment objective.

Global economies are increasingly interconnected, and political, economic and other conditions and events (including, but not limited to, natural disasters, pandemics, epidemics, and social unrest) in one country or region might adversely impact a different country or region. Furthermore, the occurrence of severe weather or geological events, fires, floods, earthquakes, climate change or other natural or man-made disasters, outbreaks of disease, epidemics and pandemics, malicious acts, cyber-attacks or terrorist acts, among other events, could adversely impact the performance of a Fund. These events may result in, among other consequences, closing borders, exchange closures, health screenings, healthcare service delays, quarantines, cancellations, supply chain disruptions, lower consumer demand, market volatility and general uncertainty. These events could adversely impact issuers, markets and economies over the short- and long-term, including in ways that cannot necessarily be foreseen. A Fund could be negatively impacted if the value of a portfolio holding were harmed by political or economic conditions or events. Moreover, negative political and economic conditions and events could disrupt the processes necessary for the Funds’ operations.

Mezzanine Securities Risk

Mezzanine securities generally are rated below investment grade and frequently are unrated and present many of the same risks as senior loans, second lien loans and non-investment grade bonds. However, unlike senior loans and second lien loans, mezzanine securities are not a senior or secondary secured obligation of the related borrower. They typically are the most subordinated debt obligation in an issuer’s capital structure. Mezzanine securities also may often be

unsecured. Mezzanine securities therefore are subject to the additional risk that the cash flow of the related borrower and the property securing the loan may be insufficient to repay the scheduled payments after giving effect to any senior obligations of the related borrower. Mezzanine securities are also expected to be a highly illiquid investment. Mezzanine securities will be subject to certain additional risks to the extent that such loans may not be protected by financial covenants or limitations upon additional indebtedness. Investment in mezzanine securities is a highly specialized investment practice that depends more heavily on independent credit analysis than investments in other types of debt obligations.

Mortgage-Backed Securities Risk

Mortgage-backed securities represent participation interests in pools of mortgage loans purchased from individual lenders by a federal agency or originated and issued by private lenders. Mortgage-backed securities are subject to prepayment risk, which is the risk that in times of declining interest rates, an issuer of mortgage-backed securities or other debt securities may be able to repay principal prior to the security’s maturity, causing a Fund to have to reinvest in securities with a lower yield or higher risk of default and reducing a Fund’s income or return potential. Mortgage-backed securities are also subject to extension risk, which is the risk that in times of rising interest rates, borrowers may pay off their debt obligations more slowly, causing the market value of such securities to decline and delaying a Fund’s ability to reinvest proceeds at higher interest rates.

Because of prepayment risk and extension risk, mortgage-backed securities react differently to changes in interest rates than other bonds, and the values of some mortgage-backed securities may expose a Fund to a lower rate of return upon reinvestment of principal. When interest rates rise, the value of mortgage-related securities generally will decline; however, when interest rates are declining, the value of mortgage-related securities with prepayment features may not increase as much as other fixed income securities. The rate of prepayments on underlying mortgages will affect the price and volatility of a mortgage-related security, and may shorten or extend the effective maturity of the security beyond what was anticipated at the time of purchase. If unanticipated rates of prepayment on underlying mortgages increase the effective maturity of a mortgage-related security, the volatility of the security can be expected to increase. The value of these securities may fluctuate in response to the market’s perception of the creditworthiness of the issuers.

Additionally, although mortgages and mortgage-related securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations. Certain mortgage-backed securities are issued or guaranteed by U.S. government agencies or U.S. government-sponsored entities. While mortgage-backed securities issued by Government National Mortgage Association (Ginnie Mae) are backed by the full faith and credit of the U.S. government, mortgage-backed securities issued by various U.S. government-sponsored entities, such as Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal National Mortgage Corporation (Fannie Mae), are not backed by the full faith and credit of the U.S. government. Although the U.S. government has provided financial support to Fannie Mae and Freddie Mac, there is no assurance that the U.S. government will do so in the future.

Portfolio Management Risk

Portfolio management risk is the risk that an investment strategy may fail to produce the intended results. There can be no assurance that a Fund will achieve its investment objective. The Adviser’s judgments about the attractiveness, value and potential appreciation of particular securities may prove to be incorrect, and the Adviser may not anticipate actual market movements or the impact of economic conditions generally. No matter how well a portfolio manager evaluates market conditions, the securities a portfolio manager chooses may fail to produce the intended result, and you could lose money on your investment in a Fund.

Prepayment Risk

Prepayment risk arises when interest rates fall because 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. In periods of falling interest rates, the rate of prepayments tends to increase as borrowers are more likely to pay off debt and refinance at new lower rates. During these periods, reinvestment of the prepayment proceeds will generally be at lower rates of return than the return on the assets that were prepaid. Prepayment reduces the yield to maturity and the average life of the security.

Price Volatility Risk

The value of a Fund’s investment portfolio will change as the prices of its investments go up or down. Different parts of the market and different types of securities can react differently to developments. Issuer, political or economic developments can affect a single issuer, issuers within an industry or economic sector or geographic region or market as a whole.

Prices of most securities tend to be more volatile in the short-term. Therefore, if you trade frequently or redeem in the short-term, you are more likely to incur a loss than an investor who holds investments for the longer-term. The fewer the number of issuers in which a Fund invests, the greater the potential volatility of its portfolio.

Securities Selection Risk

The specific securities held in a Fund’s investment portfolio may underperform those held by other funds investing in the same asset class or those included in benchmarks that are representative of the same asset class because of a portfolio manager’s choice of securities.

Swap Agreements Risk

Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than a year. Swap transactions attempt to obtain a particular return when it is considered desirable to do so, possibly at a lower cost to a Fund than if the Fund had invested directly in an instrument that yielded that desired return. In a standard swap transaction, two parties agree to exchange the returns earned on specific assets, such as the return on, or increase in value of, a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. Whether a Fund’s use of swap agreements will be successful in furthering its investment objectives will depend on the Adviser’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments.

Credit default swaps involve parties effectively buying or selling protection with respect to whether an event of default by a selected entity (or entities) will occur. Interest rate swaps involve the exchange of interest payments by a Fund with another party, such as an exchange of floating rate payments for fixed interest rate payments. A total return swap is the generic name for any swap where one party agrees to pay the other the “total return” of a defined underlying asset, usually in return for receiving a stream of cash flows. Total return swaps are most commonly used with indices, single stocks, bonds and defined portfolios of loans and mortgages.

Risks inherent in the use of swaps of any kind include: (1) swap contracts may not be assigned without the consent of the counterparty; (2) potential default of the counterparty to the swap if it is not subject to centralized clearing; (3) absence of a liquid secondary market for any particular swap at any time; and (4) possible inability of a Fund to close out the swap transaction at a time that otherwise would be favorable for it to do so.

Certain types of over-the-counter (“OTC”) derivatives, such as various types of swaps, are required to be cleared through a central clearing organization that is substituted as the counterparty to each side of the transaction. Each party will be required to maintain its positions through a clearing broker. Although central clearing generally is expected to reduce counterparty risk, it creates additional risks. A clearing broker or organization may not be able to perform its obligations. Cleared derivatives transactions may be more expensive to maintain than OTC transactions, or require a Fund to deposit increased margin. A transaction may be subject to unanticipated close-out by the clearing organization or a clearing broker. A Fund may be required to indemnify a swap execution facility or a broker that executes cleared swaps against losses or costs that may be incurred as a result of the Fund’s transactions. A Fund also is subject to the risk that no clearing member is willing to clear a transaction entered into by the Fund.

The U.S. and foreign governments have adopted and implemented, or are in the process of adopting and implementing, regulations governing derivatives markets, including clearing, margin, reporting, and registration requirements. The ultimate impact of the regulations remains unclear. The effect of the regulations could be, among other things, to restrict a Fund’s ability to engage in swap transactions or increase the costs of those transactions.

Unrated Securities Risk

A Fund may purchase unrated securities (which are not rated by a rating agency) if the Adviser determines that the security is of comparable quality to a rated security that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that the Adviser may not accurately evaluate the security’s comparative credit rating. Analysis of creditworthiness of issuers of high yield securities may be more complex than for issuers of higher-quality fixed income securities. To the extent that a Fund invests in high yield and/or unrated securities, the Fund’s success in achieving its investment objective may depend more heavily on the Adviser’s creditworthiness analysis than if the Fund invested exclusively in higher-quality and rated securities.

U.S. Government Securities Risk

Some U.S. government securities, such as Treasury bills, notes, and bonds and mortgage-backed securities guaranteed by Ginnie Mae, are supported by the full faith and credit of the United States, while others are supported by the right of the issuer to borrow from the U.S. Treasury, by the discretionary authority of the U.S. government to purchase the agency’s obligations, or by the credit of the issuing agency, instrumentality, or enterprise only.

In addition, certain governmental entities have been subject to regulatory scrutiny regarding their accounting policies and practices and other concerns that may result in legislation, changes in regulatory oversight and/or other consequences that could adversely affect the credit quality, availability or investment character of securities issued or guaranteed by these entities.

In recent periods, the values of U.S. government securities have been affected substantially by increased demand for them around the world. Changes in the demand for U.S. government securities may occur at any time and may result in increased volatility in the values of those securities.

U.S. Treasury Obligations Risk

While credit risk for U.S. Treasury obligations is generally considered low, U.S. Treasury obligations are subject to interest rate risk, particularly for those with longer terms. In addition, certain political events in the U.S., such as a prolonged government shut down, may cause investors to lose confidence in the U.S. government and may cause the value of U.S. Treasury obligations to decline. A significant portion of U.S. Treasury obligations is held by foreign governments, including China, Japan, Ireland and Brazil. Strained relations with these foreign countries may result in the sale of U.S. Treasury obligations by these foreign governments, causing the value of U.S. Treasury obligations to decline.

Valuation Risk

Portfolio instruments may be sold at prices different from the values established by a Fund, particularly for investments that trade in low volume, in volatile markets or over the counter or that are fair valued. Portfolio securities may be valued using techniques other than market quotations in circumstances described under “Net Asset Value and Fair Value Pricing.” This is more likely for certain types of derivatives such as swaps. The value established for a portfolio security may be different than the value that would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. A Fund may from time to time purchase an “odd lot” or smaller quantity of a security that trades at a discount to the price of a “round lot” or larger quantity preferred for trading by institutional investors. If a Fund is able to combine an odd lot purchase with an existing holding to make a round lot or larger position in the security, the Fund may be able to immediately increase the value of the security purchased, in accordance with its valuation procedures. There is no assurance that the Fund could sell a portfolio security for the value established for it at any time and it is possible that the Fund would incur a loss because a portfolio security is sold at a discount to its established value.

Borrowing and Use of Leverage Risks

Each Fund may borrow money from banks and engage in reverse repurchase transactions for temporary or emergency purposes. A Fund may borrow from broker-dealers and other institutions to leverage a transaction, provided that the borrowing is fully collateralized. Total bank borrowings may not exceed 10% of the value of a Fund’s assets, except in the case of the High Yield Bond Fund and Unconstrained Bond Fund, for which total bank borrowings may not exceed one-third of the value of the Fund’s assets. A Fund also may leverage its portfolio through margin borrowing and other techniques in an effort to increase total return. Although leverage creates an opportunity for increased income and gain, it also creates certain risks. For example, leveraging may magnify changes in the net asset values of a Fund’s shares and in its portfolio yield. Although margin borrowing will be fully collateralized, a Fund’s assets may change in value while the borrowing is outstanding. Leveraging creates interest expenses that can exceed the income from the assets retained.

Cybersecurity Risk

The use of technology is prevalent in the course of business and, as a result, the Funds have become potentially more susceptible to operational and information security risks resulting from breaches in cybersecurity. A breach in cybersecurity could result from intentional or unintentional cyber events from outside threat actors or internal resources that may, among other matters, cause a Fund to lose proprietary information, suffer data corruption and/or destruction or lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cybersecurity breaches may involve unauthorized access to a Fund’s digital information systems (e.g., through “hacking,” malicious software coding, etc.), from multiple sources including outside attacks such as denial-of-service attacks (i.e., efforts to make network services unavailable to intended users), or cyber extortion including exfiltration of data held for ransom and/or “ransomware” attacks that renders systems inoperable until ransom is paid or insider actions. In addition, cybersecurity breaches involving a Fund’s third-party service providers (including but not limited to investment advisers, administrators, transfer agents, custodians, vendors, suppliers, distributors and other third parties), trading counterparties or issuers in which a Fund invests can also subject a Fund to many of the same risks associated with direct cybersecurity breaches or extortion of company data. Moreover, cybersecurity breaches involving trading counterparties or issuers in which a Fund invests could adversely impact these counterparties or issuers and cause the Fund’s investment to lose value. Cybersecurity failures or breaches may result in financial losses to a Fund and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with a Fund’s ability to calculate its NAV, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third-party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cybersecurity risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to seek to prevent cybersecurity incidents in the future. Like with operational risk in general, the Funds have established business continuity plans and other systems designed to reduce the risks associated with cybersecurity. However, there are inherent limitations in these plans and systems, including that certain risks may not have been identified, in large part because different or unknown threats may be unknown or emerge in the future. As such, there is no guarantee that these efforts will succeed, especially because the Funds do not directly control the cybersecurity systems of issuers in which a Fund may invest, trading counterparties or third-party service providers to the Funds. These entities may have experienced cybersecurity attacks and other attempts to gain unauthorized access to systems from time to time, and there is no guarantee that efforts to prevent or mitigate the effects of these attacks will be successful. There is also a risk that cybersecurity breaches may not be detected, or may not be detected for a meaningful period of time. The Funds and their shareholders may suffer losses as a result of a cybersecurity breach related to the Funds, their service providers, trading counterparties or the issuers in which a Fund invests.

Event Risk

Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.

Financial Services Sector Risk

Companies in the financial services sector may be affected by the overall economic conditions as well as by factors particular to the financial services sector. Financial services companies are subject to extensive government regulations, which may change frequently and may adversely affect the scope of their activities, place restrictions on the amounts and types of loans and other financial commitments they can make, limit the interest rates and fees they can charge, and

prescribe the amount of capital they must maintain. In addition, the profitability of businesses in the financial services sector depends heavily on the availability and cost of capital and may fluctuate significantly in response to changes in interest rates and may be negatively impacted by credit rating downgrades and decreased liquidity in the credit market. Businesses in the financial services sector often operate with substantial financial leverage.

Frequent Purchases and Redemptions of Fund Shares Risks

Frequent purchases and redemptions of a Fund’s shares may present certain risks for the Fund and its shareholders. These risks may include, among other things, dilution in the value of Fund shares held by long-term shareholders, interference with the efficient management of the Fund’s portfolios and increased brokerage and administrative costs. A Fund may have difficulty implementing long-term investment strategies if it is unable to anticipate what portion of its assets it should retain in cash to provide liquidity to its shareholders. Also, excessive purchases and sales or exchanges of a Fund’s shares may force a Fund to maintain a disadvantageously large cash position to accommodate short duration trading activity. Further, excessive purchases and sales or exchanges of a Fund’s shares may force the Fund to sell portfolio securities at inopportune times to raise cash to accommodate frequent trading activity, and could result in increased brokerage, tax, administrative costs or other expenses. It is anticipated that the Low Duration Bond Fund is less likely to be adversely affected under normal circumstances, and the other Funds are more likely to be significantly affected, by frequent purchases and sales.

Certain of the Funds may invest in non-U.S. securities; accordingly, there is an additional risk of undetected frequent trading in a Fund’s shares by investors who attempt to take unfair advantage of the Fund’s need to value its portfolio holdings that are traded in markets with closing times different than when the Fund calculates its net asset value, also known as time zone arbitrage. In addition, because certain of the Funds significantly invest in high yield bonds, and because these securities are often infrequently traded, investors may seek to trade Fund shares in an effort to benefit from their under- standing of the value of these securities (referred to as price arbitrage).

Investors seeking to engage in disruptive trading practices may deploy a variety of strategies to avoid detection and, despite the efforts of the Funds to prevent disruptive trading, there is no guarantee that the Funds or their agents will be able to identify such investors or curtail their trading practices. The ability of the Funds and their agents to detect and curtail excessive trading or short duration trading practices may also be limited by operational systems and technological limitations. In addition, the Funds receive purchase, exchange and redemption orders through financial intermediaries. These financial intermediaries include, but are not limited to, entities such as broker-dealers, insurance company separate accounts, and retirement plan administrators. The Funds cannot always know or reasonably detect excessive trading which may be facilitated by these intermediaries or by the use of omnibus account arrangements. Omnibus accounts are common forms of holding Fund shares. Entities utilizing such omnibus account arrangements may not identify customers’ trading activity in shares of a Fund on an individual basis. Consequently, although the Fund has procedures and agreements in place intended to detect excessive trading, it may not always be able to detect frequent or excessive trading in Fund shares attributable to a particular investor who effects purchase and/or exchange activity in Fund shares through a broker, dealer or other financial intermediary acting in an omnibus capacity. Also, there may exist multiple tiers of these entities, each utilizing an omnibus account arrangement that may further compound the difficulty to the Funds of detecting excessive or short duration trading activity in Fund shares. In seeking to prevent disruptive trading practices in the Funds, the Funds consider the information actually available to them at the time. While each of these financial intermediaries may have individual policies concerning frequent or excessive trading, each intermediary has different policies. The Funds are not able to fully assess the effectiveness of its financial intermediaries’ policies concerning frequent or excessive trading. If investing through intermediaries, investors should inquire at that intermediary what frequent purchase and redemption policies will be applied to their investments.

Geopolitical Events Risk

The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in a Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, territorial invasions and global economic sanctions implemented in response, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long-term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects. Any such event(s) could have a significant adverse impact on the

value and risk profile of a Fund’s portfolio. The novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your investment in the Funds, Therefore, the Funds could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates can have the same impact on all types of securities and instruments. In times of severe market disruptions, you could lose your entire investment.

Inside Information Risks

A Fund’s portfolio managers may seek to avoid exposure to material non-public information about the issuers of floating rate loans being considered for purchased by the Fund. Although that inside information could enhance the portfolio managers’ ability to evaluate a potential investment, it would also impair the Fund’s ability to trade that issuer’s securities in compliance with federal securities laws.

LIBOR Transition Risk

LIBOR was a leading benchmark or reference rate for various commercial and financial contracts, including corporate and municipal bonds, bank loans, asset-backed and mortgage-related securities, interest rate swaps and other derivatives. In July 2017, the United Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR, announced the gradual phase out of the LIBOR rate, with nearly all LIBOR rate publications having ceased as of June 30, 2023 (some LIBOR rates continue to be published, but only on a temporary and synthetic basis). Alternatives to LIBOR have been established and others may be developed. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, has identified the Secured Overnight Financial Rate (SOFR) as the preferred alternative rate to LIBOR. SOFR is a relatively new index calculated by short-term repurchase agreements, backed by Treasury securities. There remains uncertainty surrounding the nature of any replacement rates. The transition to a new reference rate may result in (i) increased volatility or illiquidity in markets for instruments or contracts that previously relied on or still rely on LIBOR, (ii) a reduction in the value of certain instruments or contracts held by a Fund, (iii) reduced effectiveness of related Fund transactions, such as hedging, (iv) additional tax, accounting and regulatory risks, or (v) costs incurred in connection with closing out positions and entering into new trades. Any pricing adjustments to a Fund’s investments resulting from a substitute reference rate may also adversely affect a Fund’s performance and/or NAV. There is no assurance that the composition or characteristics of any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments or contracts using an alternative rate will have the same volume or liquidity.

The Adviser

Metropolitan West Asset Management, LLC, with principal offices at 515 South Flower Street, Los Angeles, California 90071, acts as the investment adviser to the Funds and generally administers the affairs of the Trust. Subject to the direction and control of the Board of Trustees, the Adviser supervises and arranges the purchase and sale of securities and other assets held in the portfolios of the Funds. The Adviser was founded in 1996, and is a wholly-owned subsidiary of TCW Asset Management Company LLC, which is a wholly-owned subsidiary of The TCW Group, Inc. (“TCW Group”). The Adviser had approximately $[  ] billion under management as of June 30, 2025. The Adviser, together with TCW Group and its other subsidiaries, which provide a variety of investment management and investment advisory services, had approximately $[  ] billion under management or committed to management, including $[  ] billion of fixed income investments, as of June 30, 2025.

Portfolio Managers

The portfolio managers who have primary responsibility for the day-to-day management of the Funds’ portfolios are listed below, together with their biographical information for the past five years. The portfolio managers select and make investments for the Funds as a team, using a consensus approach. The Statement of Additional Information provides additional information about the portfolio managers’ compensation, other accounts managed by the portfolio managers and the portfolio managers’ ownership of securities in the Funds.

Management Fees and Other Expenses

Management Fees. Each Fund pays the Adviser a monthly fee for providing investment advisory services. The following fees were the amounts paid to the Adviser for the fiscal year ended March 31, 2025: [  ]% for the High Yield Bond Fund; [  ]% for the Low Duration Bond Fund; [  ]% for the Total Return Bond Fund; and [  ]% for the Unconstrained Bond Fund. The fees paid to the Adviser were reduced for some Funds by expense limitations as shown in the prospectus summary. A discussion of the basis for the Board of Trustees’ approval of the management agreement is available in the Funds’ Semi-Annual Report for the period ended September 30, 2024.

The Investment Management Agreement permits the Adviser to recoup fees it did not charge and Fund expenses it paid, provided that those amounts are recouped within three years of being reduced or paid. The Adviser may recoup reduced fees and expenses only within three years, provided that the recoupment does not cause the Fund’s annual expense ratio to exceed the lesser of (i) the expense limitation applicable at the time of that fee waiver and/or expense reimbursement, or (ii) the expense limitation in effect at the time of recoupment. See “Operating Expenses Agreement” below for additional information.

Operating Expenses Agreement. Pursuant to an operating expenses agreement between the Adviser and the Trust, on behalf of the Funds (the “Operating Expenses Agreement”), the Adviser has agreed to waive its investment management fee and/or reimburse the operating expenses of each Fund to the extent such Fund’s operating expenses (excluding taxes, interest, brokerage commissions, dividends on securities sold short, acquired fund fees and expenses, and extraordinary expenses) exceed, in the aggregate, the rate per annum, as set forth below. The Operating Expenses Agreement will remain in effect until [  ]. In the event that the Operating Expenses Agreement is not renewed for an additional one-year term, total annual fund operating expenses would be as disclosed in the table under “Fees and Expenses of the Fund” included in each Fund’s summary section.

There are no Rule 12b-1 fees assessable for Class I-3 shares of the Funds.

Other Shareholder Servicing Expenses Paid By the Funds. Each Fund is authorized to compensate each broker-dealer and other third-party intermediary up to 0.20% (20 basis points) of the assets serviced for that Fund by that intermediary for shareholder services to each Fund and its shareholders who have invested in the I-3 Share class. These services constitute sub-recordkeeping or similar services and are similar in scope to services provided by the transfer agent to a Fund. These amounts may be adjusted, subject to approval by the Board of Trustees. These expenses paid would remain subject to any overall expense limitations applicable to that Fund.

Compensation of Other Parties. The Adviser may, at its own expense and out of its own legitimate profits or other resources, pay additional compensation to third parties such as (but not limited to) broker-dealers, investment advisers, retirement plan administrators, or other financial intermediaries that have entered into a distribution, service or other type of arrangement with the Adviser, the distributor or the Funds (“Authorized Firms”). These are payments over and above other types of shareholder servicing and distribution payments described elsewhere in this Prospectus.

Payments may relate to selling and/or servicing activities, such as: access to an intermediary’s customers or network; recordkeeping services; aggregating, netting and transmission of orders; generation of sales and other informational materials; individual or broad-based marketing and sales activities; wholesale activity; conferences; retention of assets; new sales of Fund shares; and a wide range of other activities. Compensation amounts generally vary, and can include various initial and on-going payments. Additional compensation may also be paid to broker-dealers who offer certain Funds as part of a special preferred-list or other preferred treatment program.

The Adviser does not direct the Funds’ portfolio securities transactions, or otherwise compensate broker-dealers in connection with any Fund’s portfolio transactions, in consideration of sales of Fund shares.

The Adviser also may pay financial consultants for products and/or services such as: (i) performance analytical software, (ii) attendance at, or sponsorship of, professional conferences, (iii) product evaluations and other types of investment consulting and (iv) asset/liability studies and other types of retirement plan consulting. The Adviser may also provide non-cash compensation to financial consultants, including occasional gifts, meals, or other entertainment. These activities may create, or could be viewed as creating, an incentive for such consultants or their employees or associated persons to recommend or sell shares of the Funds to their client investors.

Authorized Firms and consultants that receive these various types of payments may have a conflict of interest in recommending or selling the Funds rather than other mutual funds to their client investors, particularly if these payments exceed the amounts paid by other mutual funds.

The Adviser also manages individual investment advisory accounts. The Adviser reduces the fees charged to individual advisory accounts by the amount of the investment advisory fee charged to that portion of the client’s assets invested in the Fund.

The Transfer Agent and Administrator

BNY Mellon Investment Servicing serves as transfer agent and administrator to the Trust and also provides accounting services pursuant to servicing agreements. The business address of BNY Mellon Investment Servicing is Attention: 534453, 500 Ross Street, 154-0520, Pittsburgh, Pennsylvania 15262.

The Underwriter

TCW Funds Distributors LLC (the “Distributor”), 515 South Flower Street, Los Angeles, CA 90071, serves as the non-exclusive distributor of each class of the Funds’ shares pursuant to a Distribution Agreement (the “Distribution Agreement”) with the Trust, which is subject to annual approval by the Board after its initial two-year term. Shares of the Funds are offered and sold on a continuous basis. The Distribution Agreement is terminable without penalty with 60 days’ notice, by the Board of Trustees, by vote of holders of a majority of the Trust’s shares, or by the Distributor. The Distributor receives no compensation from the Funds for distribution of the Funds’ shares except payments pursuant to the Trust’s distribution plan adopted pursuant to Rule 12b-1 under the 1940 Act. The Distributor is affiliated with the Adviser.

Disclosure of Portfolio Holdings

A description of the Funds’ policies regarding disclosure of portfolio holdings can be found in the Statement of Additional Information.

Regular Purchases

The following table provides the Funds’ minimum initial and subsequent investment requirements for each share class. The minimums may be reduced or waived in some cases.

The price at which the Funds’ shares are bought or sold is called the net asset value per share, or “NAV.” The NAV is computed once daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), generally 4:00 p.m. Eastern Time, on each day that the NYSE is open for trading. In addition to Saturday and Sunday, the NYSE is closed on the days that the following holidays are observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Shares cannot be purchased by wire transactions on days when banks are closed. The Funds may close early on business days that the Securities Industry and Financial Markets Association recommends that the bond markets close early.

The price for each share you buy will be the NAV calculated after your request is received in good order by the Fund. “In good order” means that payment for your purchase and all the information needed to complete your order must be received by the Fund before your order is processed. If your order is received before the close of regular trading on the NYSE (generally 4:00 p.m. Eastern Time) on a day the Funds’ NAVs are calculated, the price you pay will be that day’s NAV. If your order is received after the close of regular trading on the NYSE, the price you pay will be the next NAV calculated. Orders received by the Funds’ Transfer Agent from dealers, brokers or other service providers, which may include the Funds’ Adviser on behalf of its separate account clients, after the NAV for the day is determined will receive that same day’s NAV if the orders were received by the financial intermediary from its customers prior to 4:00 p.m. Eastern time (or the time trading closes on the NYSE, whichever is earlier). Your financial intermediary is responsible for transmitting such orders promptly.

The Trust and the Transfer Agent reserve the right to reject any order and to waive the minimum investment requirements for investments through certain fund networks or other financial intermediaries and for employees and affiliates of the Adviser or the Trust. In such cases, the minimums associated with the policies and programs of the fund network or other financial intermediary will apply. (In certain cases, the fund network or other financial intermediary also may waive its minimum investment requirements; the Adviser occasionally may be involved in the fund network or other financial intermediary’s decision to waive its minimum investment requirements, but does not control that decision.) This means that investors through various financial intermediaries may face different (or even substantially reduced) investment minimums than those affecting your investment. The Funds reserve the right to redeem accounts inadvertently opened with less than the minimum initial investment. The Funds at their sole discretion may impose an annual $25 account servicing fee for below minimum accounts; certain below minimum accounts may not be charged that servicing fee.

You may invest in any Fund by wiring the amount to be invested to TCW Metropolitan West Funds.

Bank Name: Bank of New York Mellon

Shareholder Fund/Account Number

Your bank may impose a fee for investments by wire. The Fund or the Transfer Agent will not be responsible for the consequences of delays, including delays in the banking or Federal Reserve wire systems. Wires received after the close of the NYSE will be considered received by the next business day.

To ensure proper credit, before wiring any funds you must call (800) 241-4671 to notify us of the wire and to get an account number assigned if the wire is an initial investment. Also, if the wire represents an initial investment, you must mail an application form, by regular mail, to the Transfer Agent. When sending applications, checks, or other communications to the Transfer Agent via regular mail, send to:

TCW Metropolitan West Funds

c/o BNY Mellon Investment Servicing

P.O. Box 534453

Pittsburgh, PA 15253-4453

If you are sending applications, checks or other communications to the Transfer Agent via overnight mail services, send to:

TCW Metropolitan West Funds

Pittsburgh, PA 15262

Make your check payable to TCW Metropolitan West Funds (Fund name). The Funds cannot accept third party checks, starter checks, credit cards, credit card checks, cash or cash equivalents (i.e., cashier’s check, bank draft, money order or travelers’ check).

Checks should be drawn on a U.S. bank and must be payable in U.S. dollars. Shares of a Fund will be purchased by the Transfer Agent or an authorized sub-agent for your account at the net asset value next determined after receipt of your wire or check. If a check is not honored by your bank, you will be liable for any loss sustained by the Fund, as well as a $20 service charge imposed by the Transfer Agent. Forms for additional contributions by check or change of address are provided on account statements.

The Trust may accept orders from selected brokers, dealers and other qualified institutions, with payment made to the Fund at a later time. The Adviser is responsible for insuring that such payment is made on a timely basis. You may be charged a fee if you buy or sell Fund shares through a broker or agent.

The Trust does not consider the U.S. Postal Service or other independent delivery service to be its agent. Therefore, deposit in the mail or other service does not constitute receipt by the Transfer Agent.

The Trust may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

The Trust generally does not permit non-U.S. residents to purchase shares of the Funds. The Trust may, at its sole discretion, make exceptions to this policy on a case-by-case basis.

Purchases By Payment in Kind

In certain situations, Fund shares may be purchased by tendering payment in kind in the form of securities. Any securities used to buy Fund shares must be readily marketable, their acquisition consistent with the Fund’s objective and otherwise acceptable to the Adviser. Prior to making such a purchase, you should call the Adviser to determine if the securities you wish to use to make a purchase are appropriate. The Funds reserve the right to reject the offer of any payment in kind.

Purchases Through an Investment Broker or Dealer

You may buy and sell shares of the Funds through certain brokers (and their agents) that have made arrangements with the Funds to sell their shares. When you place your order with such a broker or its authorized agent, your order is treated as if you had placed it directly with the Funds’ Transfer Agent, and you will pay or receive the next price calculated by the Funds. The broker (or agent) holds your shares in an omnibus account in the broker’s (or agent’s) name, and the broker (or agent) maintains your individual ownership records. The Funds may pay the broker or its agent for maintaining these records as well as providing other shareholder services. The broker (or its agent) may charge you a fee for handling your order. The broker (or agent) is responsible for processing your order correctly and promptly, keeping you advised regarding the status of your individual account, confirming your transactions and ensuring that you receive copies of the Funds’ prospectus.

Current and prospective investors purchasing shares of a Fund through a broker-dealer should be aware that a transaction charge may be imposed by broker-dealers that make the Fund’s shares available, and there will not be such a transaction charge if shares of the Fund are purchased directly from the Fund.

Identity Verification Procedures Notice

The USA PATRIOT Act and federal regulations require financial institutions, including mutual funds, to adopt certain policies and programs to prevent money laundering activities, including procedures to verify the identity of all investors opening new accounts. When completing the New Account Application, you will be required to supply the Funds with certain information for all persons owning or permitted to act on an account. This information includes date of birth, taxpayer identification number and street address. If you are opening the account in the name of a legal entity (e.g., partnership, limited liability company, business trust, corporation, etc.), you must also supply the identity of the beneficial owners. Until such verification is made, the Funds may temporarily limit additional share purchases. In addition, the Funds may limit additional share purchases or close an account if they are unable to verify a customer’s identity. As required by law, the Funds may employ various procedures, such as comparing the information to fraud databases or requesting additional information or documentation from you, to ensure that the information supplied by you is correct.

Net Asset Value and Fair Value Pricing

The NAV per share is the value of the Fund’s assets, less its liabilities, divided by the number of shares of the Fund outstanding. The value of a Fund’s portfolio securities is determined on the basis of the market value of such securities or, if market quotations are not readily available, at fair value as determined by the Adviser. The Adviser may determine the fair value for securities that are thinly traded, illiquid, or where the Adviser believes that the prices provided by a pricing service are not accurate or are not available. Fair value pricing is intended to be used as necessary in order to accurately value the Funds’ portfolio securities and their respective net asset values. The Statement of Additional Information further describes the most common techniques used by the Funds to fair value their securities.

The daily NAV may not reflect the closing market price for all futures contracts held by the Funds because the markets for certain futures will close shortly after the time net asset value is calculated. See “Net Asset Value” in the Statement of Additional Information for further information.

Regular Redemptions

You may redeem shares at any time by delivering instructions by regular mail to the Transfer Agent or selected brokers, dealers and other qualified institutions. If you would like to send a request to redeem shares to the Transfer Agent via regular mail, send to:

TCW Metropolitan West Funds

c/o BNY Mellon Investment Servicing

P.O. Box 534453

Pittsburgh, PA 15253-4453

If you are sending a request via overnight mail services, send to:

TCW Metropolitan West Funds

c/o BNY Mellon Investment Servicing

Attention: 534453

500 Ross Street, 154-0520

Pittsburgh, PA 15262

The redemption request should identify the Fund and the account number, specify the number of shares or dollar amount to be redeemed and be signed by all registered owners exactly as the account is registered. Your request will not be accepted unless it contains all required documents. The shares will be redeemed at NAV next determined after receipt of the request by the Transfer Agent or other agent of the Funds. A redemption of shares is a sale of shares and you may realize a taxable gain or loss.

If the proceeds of any redemption (a) exceed $50,000, (b) are paid to a person other than the owner of record, or (c) are sent to an address or bank account other than shown on the Transfer Agent’s records, the signature(s) on the redemption request must be a medallion signature guarantee. A medallion signature guarantee may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association, or other financial institution which is participating in a medallion program recognized by the Securities Transfer Association. The three recognized medallion programs are Securities Transfer Agents Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP) and New York Stock Exchange, Inc. Medallion Signature Program (NYSE MSP).

Additional documentation may be required for the redemption of shares held in corporate, partnership or fiduciary accounts. If you have any questions, please contact the Funds in advance by calling (800) 241-4671.

Redemptions will be processed only on a day during which the NYSE is open for business. If you purchase shares by check or money order and later decide to sell them, your proceeds from that redemption will be withheld until the Funds are sure that your check has cleared. This could take up to 15 calendar days after your purchase order.

Exchanges of Shares

You are permitted to exchange your shares in a Fund for shares of another Fund in the Trust, provided that the share class is the same in the two Funds involved in the exchange, the shares may legally be sold in the state of your residence and the Fund is open to new investors. You must also select the appropriate box on the Account Application. The shares you are exchanging must have a current value of at least the minimum investment requirement for that class ($[ ] for regular accounts of Class I-3). An exchange of shares is treated for Federal income tax purposes as a redemption or sale of shares and any gain or loss may be subject to income tax. Shares exchanged for shares of another Fund will be priced at their respective net asset values.

The exchange privilege is not intended as a vehicle for short-term trading. Excessive exchange activity may interfere with portfolio management and have an adverse effect on all shareholders. Administrators, trustees or sponsors of retirement plans may also impose redemption fees on such exchanges.

The Funds also reserve the right to revise or terminate the exchange privilege, limit the amount or number of exchanges or reject any exchange. The Fund into which you would like to exchange may also reject your exchange. These actions may apply to all shareholders or only to those shareholders whose exchanges the Adviser determines are likely to have a negative effect on the Funds.

Systematic Withdrawal Plan

[If you own or are purchasing shares of the Funds having a current value of at least [$10,000 for Class M and Administrative Class and $100,000 for Class I and Class I-2, you may participate in a Systematic Withdrawal Plan. The Systematic Withdrawal Plan provides for automatic redemptions of at least $100 on a monthly for Class M and Administrative Class, quarterly, semi-annual or annual basis via Automatic Clearing House (ACH).] This electronic transfer could take three to five business days to settle. You may establish a Systematic Withdrawal Plan by completing the appropriate section on the Account Application or by calling the Funds at (800) 241-4671. Notice of all changes concerning the Systematic Withdrawal Plan must be received by the Transfer Agent at least two weeks prior to the next scheduled payment. Further information regarding this Plan and its requirements can be obtained by contacting the Fund at (800) 241-4671. The Systematic Withdrawal Plan is not available for the Plan Class shares.]

Telephone Transactions

You may redeem shares by telephone and have the proceeds wired to the bank account as stated on the Transfer Agent’s records. You may also exchange shares by telephone. In order to redeem or exchange shares by telephone, you must select the appropriate box on the Account Application. In order to arrange for telephone redemptions or exchanges or change payment instructions after an account has been opened or to change the bank account or address designated to receive redemption proceeds, a written request must be sent to the Trust. The request must be signed by each shareholder of the account with the signature guarantees as described above. Once this feature has been requested, shares may be redeemed or exchanged by calling the Transfer Agent at (800) 241-4671 and giving the account name, account number, and amount of the redemption or exchange. Joint accounts require only one shareholder to call. If redemption proceeds are to be mailed or wired to the shareholder’s bank account, the bank involved must be a commercial bank located within the United States.

If you redeem your shares by telephone and request wire payment, payment of the redemption proceeds will normally be made in Federal funds on the next business day. The redemption order must be received by the Transfer Agent before the relevant Fund’s net asset value is calculated for the day. There may be a charge of up to $10 for all wire redemptions. IF YOU EFFECT TRANSACTIONS VIA WIRE TRANSFER YOU MAY BE REQUIRED TO PAY FEES, INCLUDING THE WIRE FEE AND OTHER FEES THAT WILL BE DEDUCTED DIRECTLY FROM REDEMPTION PROCEEDS.

The Funds reserve the right to reject any telephone redemption or exchange request and the redemption or exchange privilege may be modified or terminated at any time on 30-days’ notice to shareholders. In an effort to prevent unauthorized or fraudulent redemption or exchange requests by telephone, the Trust and the Transfer Agent employ reasonable procedures specified by the Funds to confirm that such instructions are genuine. Among the procedures used to determine authenticity, if you are electing to redeem or exchange by telephone you will be required to provide your account number or other identifying information. All such telephone transactions will be digitally recorded and you will receive a confirmation in writing. The Trust may implement other procedures from time to time. If reasonable procedures are not implemented, the Trust and/or the Transfer Agent may be liable for any loss due to unauthorized or fraudulent transactions. In all other cases, the shareholder is liable for any loss for unauthorized transactions. In periods of severe market or economic conditions, the telephone redemption or exchange of shares may be difficult to implement and you should redeem shares by writing to the Transfer Agent at the address listed above. If for any other reason you are unable to redeem or exchange by telephone, you should redeem or exchange shares by writing to the Transfer Agent at the address listed above.

Payments

After the Transfer Agent has received the redemption request and all proper documents, payment for shares tendered will generally be made within (i) one to three business days for redemptions made by wire, and (ii) three to five business days for ACH redemptions. Redemption payments by check will generally be issued on the business day following the redemption date; however, actual receipt of the check by the redeeming investor will be subject to postal delivery schedules and timing. Payment may be delayed under unusual circumstances, consistent with the 1940 Act, and may take up to several weeks when made partly in-kind with marketable securities.

Methods Used to Meet Redemption Requests

Under normal circumstances, each Fund typically expects to meet redemptions with other positive cash flows. When that cash is not available, each Fund seeks to maintain its portfolio weightings by selling a cross section of the Fund’s holdings to meet redemptions, while also factoring in trading costs.

Under certain circumstances, including under stressed market conditions, there are additional tools that each Fund may use in order to meet redemptions, including advancing the settlement of market trades with counterparties to match investor redemption payments or delaying settlement of an investor’s transaction to match trade settlement, within regulatory requirements. Under unusual circumstances, a Fund may also borrow money (subject to certain regulatory conditions) through a bank line of credit, including a joint committed credit facility, or inter-fund borrowing from affiliated mutual funds, in order to meet redemption requests.

If the Board of Trustees determines that it would be detrimental to the best interests of the remaining shareholders of the Fund to make payment wholly in cash, the Fund may pay the redemption price in part by a distribution in kind of readily marketable securities from the portfolio of the Fund, in lieu of cash. The Trust has elected to be governed by Rule 18f-1 under the 1940 Act, pursuant to which the Fund is obligated to redeem shares solely in cash up to the lesser of $250,000 or one percent of the net asset value of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation the Fund will have the option of redeeming the excess in cash or in kind. If shares are redeemed in kind, the redeeming shareholder would incur brokerage costs in converting the assets into cash.

Redemptions of Accounts Below Minimum Amount

The Funds may redeem all of your shares at net asset value (calculated on the preceding business day) if the balance of your account falls below a certain minimum amount as a result of a transfer or redemption (and not market fluctuations). The minimum amount is [$3,000,000 for Class I-3 shares]. The Funds will notify you in writing and you will have 60 days to increase your account balance before your shares are redeemed.

Conversion of Shares Between Classes

You are permitted to convert shares between Class M, Class I, Class I-2, [Class I-3] and Plan Class Shares, provided that your investment meets the minimum initial investment and any other requirements in the other class, and that the shares of the other class are eligible for sale in your state of residence. Further information about conversion of shares between classes may be found in the Statement of Additional Information.

Trading Limits

The Funds are not intended to serve as vehicles for frequent trading activity because such trading may disrupt management of the Funds. In addition, such trading activity can increase expenses as a result of increased trading and transaction costs, forced and unplanned portfolio turnover, lost opportunity costs, and large asset swings that decrease the Funds’ ability to provide maximum investment returns to all shareholders. In addition, certain trading activity that attempts to take advantage of inefficiencies in the valuation of the Funds’ securities holdings may dilute the interests of the remaining shareholders. This in turn can have an adverse effect on the Funds’ performance.

The Trust reserves the right to refuse any purchase or exchange request that could adversely affect a Fund or its operations, including those from any individual or group who, in the Trust’s view, is likely to engage in excessive material trading. If a purchase or exchange order into shares of a Fund is rejected, the potential investor will not benefit from any subsequent increase in the net asset value of that Fund. Future purchases into a Fund may be barred if a shareholder effects more than two round trips in shares of that Fund (meaning exchanges or redemptions following a purchase) in excess of certain de minimis limits within a 30 day period. Shareholders effecting a round trip transaction in shares of a Fund in excess of the relevant de minimis threshold more than once within the above-referenced 30-day period may receive a communication from the Fund warning that the shareholder is in danger of violating the Trust’s Frequent Trading Policy. Exceptions to these trading limits may be made only upon approval of the Funds’ Chief Compliance Officer or his designee, and such exceptions are reported to the Board of Trustees on a quarterly basis. This policy may be revised from time to time by the officers of the Trust in consultation with the Board of Trustees without prior notice.

These restrictions do not apply to certain asset allocation programs (including mutual funds that invest in other mutual funds for asset allocation purposes, and not for short-term trading), to omnibus accounts (except to the extent noted in the next paragraph) maintained by brokers and other financial intermediaries (including 401(k) or other group retirement accounts, although restrictions on Fund share transactions comparable to those set forth in the previous paragraph have been applied to the Adviser’s retirement savings program), and to involuntary transactions and automatic investment programs, such as dividend reinvestment, or transactions pursuant to the Funds’ systematic investment or withdrawal program.

In an attempt to detect and deter excessive trading in omnibus accounts, the Trust or its agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. The Funds’ ability to impose restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries. The Trust, however, cannot always identify or reasonably detect excessive trading that may be facilitated by financial intermediaries or made difficult to identify through the use of omnibus accounts by those intermediaries that transmit purchase, exchange and redemption orders to the Funds, and thus the Funds may have difficulty curtailing such activity.

In addition, the Trust reserves the right to:

Reports to Shareholders

Each Fund’s fiscal year ends on March 31. Each Fund will issue to its shareholders semi-annual and annual reports. In addition, you will receive monthly statements of the status of your account reflecting all transactions having taken place within that month. In order to reduce the Funds’ expenses, the Trust will try to identify related shareholders in a household and send only one copy of the annual or semi-annual report and prospectus per household. Information regarding the tax status of income dividends and capital gains distributions will be mailed to shareholders by the deadline established by the Internal Revenue Service (IRS). Account tax information will also be sent to the IRS.

Withholdings; Reporting

The Funds may be required to withhold Federal income tax from proceeds of redemptions if you are subject to backup withholding. Failure to provide a certified tax identification number at the time an account is opened will cause tax to be withheld. The Funds also may be required to report redemptions to the IRS.

The Funds expect to declare dividends daily and pay them monthly to shareholders. Dividends normally begin to accrue on the next business day after payment for shares.

Distributions from net realized short-term gains, if any, and distributions from any net capital gains realized through October 31st of each year and not previously paid out will be paid out after that date. Each Fund may also pay supplemental distributions after the end of the Fund’s fiscal year. Dividends and distributions are paid in full and fractional shares of each Fund based on the net asset value per share at the close of business on the ex-dividend date, unless you request, in writing to the Trust, payment in cash. Distributions are treated the same for tax purposes whether received in cash or reinvested. The Trust will notify you after the close of its fiscal year of both the dollar amount and the tax status of that year’s distributions. All dividends from net investment income (other than qualified dividend income) together with distributions of short-term capital gains will be taxable as ordinary income even if paid to you in additional shares. Any net capital gains (“capital gains distributions”) distributed are taxable as the relevant type of capital gains regardless of the length of time you have owned your shares. Distributions of investment income designated as derived from “qualified dividend income” will be taxed under federal law in the hands of individuals at the rates applicable to long term capital gain, provided certain requirements are met. State and local taxes may also apply. Dividends, interest and gains received by a Fund may be subject to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the U.S. may reduce or eliminate these foreign taxes.

Distributions will be taxable in the year in which they are received, except for certain distributions received in January, which will be taxable as if received the prior December. You will be informed annually of the amount and nature of the Fund’s distributions, including the portions, if any, that qualify for the dividends-received deduction. These distributions may be capital gain distributions and/or a return of capital.

Additional information about taxes is set forth in the Statement of Additional Information. The foregoing discussion has been prepared by the management of the Funds, and is not intended to be a complete description of all tax implications of an investment in a Fund. You should consult your own advisors concerning the application of federal, state and local tax laws to your particular situations.
