The Fund's investment advisor, TCW Investment Management Company LLC (the "Advisor"), has agreed to waive fees and/or reimburse expenses to limit the Fund's total annual operating expenses (excluding interest, brokerage, extraordinary expenses and acquired fund fees and expenses, if any) to 0.60% of average daily net assets with respect to Class I shares and 0.70% of average daily net assets with respect to Class N shares. The Advisor may recoup reduced fees and expenses within three years of the waiver or reimbursement, provided that the recoupment does not cause the Fund's annual expense ratio to exceed (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. This contractual fee waiver/expense reimbursement will remain in place through March 1, 2027 and before that date, the investment advisor may not terminate this arrangement without approval of the Board of Directors. At the conclusion of this period, the Fund's investment advisor may, in its sole discretion, terminate the contractual fee waiver/expense reimbursement or, with the Board of Directors' approval, extend or modify that arrangement.

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.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all 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 of investing in the Fund reflects the net expenses of the Fund that result from the contractual expense limitation in the first year only (through March 1, 2027). Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Share Classes

1 Year 3 Years 5 Years 10 Years

I

$ 187 $ 579 $ 995 $ 2,159

N

$ 218 $ 673 $ 1,154 $ 2,483

Portfolio Turnover

The Fund pays transaction costs 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 266.31% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of the value of its net assets, plus any borrowings for investment purposes, in debt securities. If the Fund changes this investment policy, it will notify shareholders in writing at least 60 days in advance of the change. The Fund may invest in various types of debt securities, including but not limited to securities issued or guaranteed by the United States government or its agencies, instrumentalities or sponsored corporations; corporate obligations (including convertible securities); mortgage-backed and asset-backed securities (which may be privately issued); local currency- or U.S. dollar-denominated foreign debt securities (corporate and government); money market instruments; structured notes; participation interests in loans; "zero-coupon" or "stripped" securities; and other debt obligations bearing fixed or variable

1

interest rates of any maturity. The Fund may also purchase or sell securities on a when-issued, delayed delivery or forward commitment basis.

Under normal market conditions, the Fund invests in securities of issuers located in at least three different countries (one of which may be the United States) and invests at least 30% of its net assets in securities of issuers located outside the United States. The Fund invests in corporate debt securities of issuers in a number of countries, which may include the United States. The Fund invests in securities of issuers located in developed and emerging market countries. The Fund may invest across all fixed-income sectors, including U.S. and non-U.S. government securities. The Fund's investments may be denominated in local currency or U.S. dollars. The Fund may invest in debt securities with a range of maturities from short- to long-term.

The Fund does not limit its investments to a particular credit or ratings category and may invest up to 35% of its net assets in below investment grade bonds (commonly referred to as "junk bonds"), which are bonds rated below BBB by S&P Global Ratings or below Baa by Moody's Investors Service, Inc., or, if unrated, bonds deemed by the Fund's investment advisor to be of comparable quality.

The Fund may invest in derivatives such as options, forward contracts, futures contracts and swaps (including interest rate swaps, total return swaps, and credit default swaps) for investment management (e.g., to increase or decrease the Fund's exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, to adjust its currency exposure relative to its benchmark index, or to earn income and enhance returns) or hedging purposes. The Fund's exposure to derivatives will vary.

In selecting securities or other instruments, the portfolio managers evaluate the overall investment opportunities and risks in individual national economies. The portfolio managers analyze the business cycle as well as political and macroeconomic factors that affect exchange rates and interest rates in both emerging markets and developing countries. In addition to considering broad economic factors, the portfolio managers apply a "bottom-up" approach in choosing investments for the Fund. This means that the portfolio managers conduct fundamental research on each individual security and determine whether the security is an attractive investment opportunity for the Fund based upon the risk adjusted cash flow characteristics of the security.

Portfolio securities or other instruments may be sold for a number of reasons, including when the portfolio managers believe that (i) another security or instrument may offer a better investment opportunity, (ii) there has been a deterioration in the credit fundamentals of the issuer, (iii) an individual security or instrument has reached its sell target, or (iv) the portfolio should be rebalanced for diversification or portfolio weighting purposes.

Principal Risks

Since 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 of the Fund are:

• debt securities risk: the risk that the value of a debt security may increase or decrease as a result of various factors, including changes in interest rates, actual or perceived inability or unwillingness of issuers to make principal or interest payments, market fluctuations and illiquidity in the debt securities market.
• market risk: the risk that returns from the securities in which the Fund invests may underperform returns from the general securities markets or other types of securities.
• market and geopolitical events risk: the risk that 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 the 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, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.
• interest rate risk: the risk that debt securities will decline in value because of changes in interest rates. This risk is greater during periods of rising inflation.
• credit risk: the risk that an issuer will default in the payment of principal and/or interest on a security.
• price volatility risk: the risk that the value of the Fund's investment portfolio will change as the prices of its investments go up or down.

2

• issuer risk: the risk that the value of a security may decline for reasons directly related to the issuer such as management performance, financial leverage and reduced demand for the issuer's goods or services.
• liquidity risk: the risk that lack of a ready market or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price. In addition, the Fund, by itself or together with other accounts managed by the investment advisor, may hold a position in a security that is large relative to the typical trading volume for that security, which can make it difficult for the Fund to dispose of the position at an advantageous time or price. Over recent years, the fixed-income markets have grown more than the ability of dealers to make markets, which can further constrain liquidity and increase the volatility of portfolio valuations. High levels of redemptions in bond funds in response to market conditions could cause greater losses as a result. 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 the Fund's assets may change over time.
• frequent trading risk: the risk that frequent trading will lead to increased portfolio turnover and higher transaction costs, which may reduce the Fund's performance and may cause higher levels of current tax liability to shareholders in the Fund.
• valuation risk: the risk that the portfolio instruments may be sold at prices different from the values established by the Fund, particularly for investments that trade in low volume, in volatile markets or over the counter or that are fair valued.
• foreign investing risk: the risk that Fund share prices will fluctuate with market conditions, currency exchange rates and the economic and political climates of the foreign countries in which the Fund invests or has exposure. Investments in foreign securities may involve greater risks than investing in U.S. securities due to, among other factors, less publicly available information, less stringent and less uniform accounting, auditing and financial reporting standards, less liquid and more volatile markets, higher transaction and custody costs, additional taxes, less investor protection, delayed or less frequent settlement, 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.
• foreign currency risk: the risk that foreign currencies will decline in value relative to the U.S. dollar and affect the Fund's investments in foreign currencies, in securities that are denominated, trade, and/or receive revenues in foreign currencies, or in derivatives that provide exposure to foreign currencies.
• non-U.S. sovereign debt risk: the risk that investments in debt obligations of non-U.S. sovereign governments may lose value due to the government entity's unwillingness or inability to repay principal and interest when due in accordance with the terms of the debt obligation or otherwise in a timely manner. The Fund may have limited (or no) recourse in the event of a default because bankruptcy, moratorium and other similar laws applicable to issuers of sovereign debt obligations may be substantially different from those applicable to private issuers and any recourse may be subject to the political climate in the relevant country.
• emerging market country risk: the risk of investing in emerging market countries, which is substantial due to, among other factors, different accounting standards; thinner trading markets as compared to those in developed countries; less publicly available and reliable information about issuers as compared to developed markets; the possibility of currency transfer restrictions; and the risk of expropriation, nationalization or other adverse political, economic or social developments.
• junk bond risk: the risk that junk bonds have a higher degree of default risk and may be less liquid and subject to greater price volatility than investment grade bonds.
• prepayment risk: the risk that in times of declining interest rates, the Fund's higher yielding securities may be prepaid and the Fund may have to replace them with securities having a lower yield.
• extension risk: 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.
• mortgage-backed securities risk: the risk of investing in mortgage-backed securities, including prepayment risk and extension risk. Mortgage-backed securities react differently to changes in interest rates than other bonds, and some mortgage-backed securities are not backed by the full faith and credit of the U.S. government.
•

U.S. government securities risk: the risk that debt securities issued or guaranteed by certain U.S. government agencies,

3

instrumentalities, and sponsored enterprises are not supported by the full faith and credit of the U.S. government, and as so investments in their securities or obligations issued by them involve credit risk greater than investments in other types of U.S. government securities.

• derivatives risk: the risk of investing in derivative instruments, which includes liquidity, interest rate, market, credit and management risks as well as risks related to mispricing or improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, reference rate or index, and the Fund could lose more than the principal amount invested. These investments can create investment leverage and may create additional risks that may subject the Fund to greater volatility and less liquidity than investments in more traditional securities.
• when-issued and delayed delivery securities and forward commitments risk: when-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security's price.
• leverage risk: the risk that leverage may result from certain transactions, including the use of derivatives and borrowing. This may impair the 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.
• counterparty risk: the risk that the other party to a contract, such as a derivatives contract, will not fulfill its contractual obligations.
• portfolio management risk: the risk that an investment strategy may fail to produce the intended results.
• securities selection risk: the risk that the securities held by the Fund may underperform those held by other funds investing in the same asset class or benchmarks that are representative of the asset class because of the portfolio managers' choice of securities.
• cybersecurity risk: the risk that, with the increased use of technology to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund's ability to calculate its net asset value, impediments to trading, the inability of shareholders to transact business,

violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

• large shareholder risk: the risk that certain account holders, including the Advisor or funds or accounts over which the Advisor (or related parties of the Advisor) has investment discretion, may from time to time own or control a significant percentage of the Fund's shares. The Fund is subject to the risk that a redemption by those shareholders of all or a portion of their Fund shares, including as a result of an asset allocation decision made by the Advisor (or related parties of the Advisor), will adversely affect the Fund's performance if it is forced to sell portfolio securities or invest cash when the Advisor would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund's portfolio, increase the Fund's transaction costs, and accelerate the realization of taxable income and/or gains to shareholders.

Please see "Principal Risks of the Funds" in the Fund's Prospectus 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.
