Dunham Funds are distributed by Dunham & Associates Investment Counsel, Inc., a Registered Investment Adviser and Broker/Dealer. Member FINRA / SIPC.

Returns for Class A Shares include the maximum sales charge (5.75% for equity funds and 4.50% for fixed income funds). Net Asset Value (NAV) returns exclude these charges, which would have reduced returns.

Average annual total return is the annual compound return for the indicated period. It reflects the change in share price and the reinvestment of all dividends and capital gains. Returns for periods of less than one year are cumulative total returns.

Lower-Rated Securities Risk - Securities rated below investment-grade, sometimes called “high-yield” or “junk” bonds, generally have more credit risk than higher-rated securities. Companies issuing high-yield fixed-income securities are not as strong financially as those issuing securities with higher credit ratings. These companies are more likely to encounter financial difficulties and are more vulnerable to changes in the economy, such as a recession or a sustained period of rising interest rates, which could affect their ability to make interest and principal payments. If an issuer stops making interest and/or principal payments, payments on the securities may never resume. These securities may be worthless and the Fund could lose its entire investment.

Credit Risk - Issuers of fixed-income securities may default on interest and principal payments due to the Fund. Generally, securities with lower debt ratings have speculative characteristics and have greater risk the issuer will default on its obligation. Fixed-income securities rated in the fourth classification by Moody’s (Baa) and S&P (BBB) may have some speculative characteristics and changes in economic conditions or other circumstances are more likely to lead to a weakened capacity of those issuers to make principal or interest payments, as compared to issuers of more highly rated securities. High-yield fixed-income securities (also known as “junk bonds”) are considered speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations. This means that, compared to issuers of higher rated securities, issuers of medium and lower rated securities are less likely to have the capacity to pay interest and repay principal when due in the event of adverse business, financial or economic conditions and/or may be in default or not current in the payment of interest or principal. The market values of medium- and lower-rated securities tend to be more sensitive to company-specific developments and changes in economic conditions than higher-rated securities. The companies that issue these securities often are highly leveraged, and their ability to service their debt obligations during an economic downturn or periods of rising interest rates may be impaired. In addition, these companies may not have access to more traditional methods of financing, and may be unable to repay debt at maturity by refinancing. The risk of loss due to default in payment of interest or principal by these issuers is significantly greater than with higher-rated securities because medium- and lower-rated securities generally are unsecured and subordinated to senior debt. Default, or the market’s perception that an issuer is likely to default, could reduce the value and liquidity of securities held by the Fund, thereby reducing the value of your investment in Fund shares. In addition, default may cause the Fund to incur expenses in seeking recovery of principal or interest on its portfolio holdings.

Interest Rate Risk - Debt securities have varying levels of sensitivity to changes in interest rates. In general, the price of a debt security may fall when interest rates rise. Securities with longer maturities may be more sensitive to interest rate changes. Certain corporate bonds and mortgage-backed securities may be significantly affected by changes in interest rates. Some mortgage-backed securities may have a structure that makes their reaction to interest rates and other factors difficult to predict, making their value highly volatile. Because zero coupon securities do not make interest payments, they are considered more volatile than bonds making periodic payments. When interest rates rise, zero coupon securities fall more sharply than interest paying bonds. However, zero coupon securities rise more rapidly in value when interest rates drop.

Call or Redemption Risk - As interest rates decline, issuers of high-yield bonds may exercise redemption or call provisions. This may force the Fund to redeem higher yielding securities and replace them with lower yielding securities with a similar risk profile. This could result in a decreased return.

Changing Fixed Income Market Conditions Risk - During periods of sustained rising rates, fixed income risks will be amplified. If the U.S. Federal Reserve’s Federal Open Market Committee (“FOMC”) raises the federal funds interest rate target, interest rates across the U.S. financial system may rise. However, the magnitude of rate changes across maturities and borrower sectors is uncertain. Rising rates tend to decrease liquidity, increase trading costs, and increase volatility, all of which make portfolio management more difficult and costly to the Fund and its shareholders. Additionally, default risk increases when issuers borrow at higher rates. Prolonged declines in the Fund’s share price may lead to increased redemption requests by shareholders. To meet redemption requests, the Fund may have to sell securities in times of overall market turmoil, lower liquidity and declining prices. Generally, each of these changing market conditions risks may cause the Fund’s share price to fluctuate or decline more than other types of investments.

Private Placement Risk - The Fund may invest in privately issued securities, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended. Privately issued securities are restricted securities that are not registered with the SEC. Accordingly, the liquidity of the market for specific privately issued securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Privately issued securities that the Adviser determines to be “illiquid” are subject to the Fund’s policy of not investing more than 15% of its net assets in illiquid securities.

Liquidity Risk - Liquidity Risk: The markets for high-yield, convertible and certain lightly traded equity securities (particularly small cap issues) are often not as liquid as markets for higher-rated securities or large cap equity securities. For example, relatively few market makers characterize the secondary markets for high-yield debt securities, and the trading volume for high-yield debt securities is generally lower than that for higher-rated securities. Accordingly, these secondary markets (generally or for a particular security) could contract under real or perceived adverse market or economic conditions. These factors may have an adverse effect on the Fund’s ability to dispose of particular portfolio investments and may limit the ability of the Fund to obtain accurate market quotations for purposes of valuing securities and calculating net asset value. Less liquid secondary markets also may affect the Fund’s ability to sell securities at their fair value. The Fund may invest in illiquid securities, which are more difficult to value and to sell at fair value. If the secondary markets for lightly-traded securities contract due to adverse economic conditions or for other reasons, certain liquid securities in the Fund’s portfolio may become illiquid, and the proportion of the Fund’s assets invested in illiquid securities may increase.

Management Risk - Each Fund is subject to management risk because it is an actively managed investment portfolio. The Sub-Adviser’s judgments about the attractiveness and potential appreciation of a security, whether selected under a “value”, “growth” or other investment style, may prove to be inaccurate and may not produce the desired results. The Adviser and Sub-Adviser will apply its investment techniques and risk analyses in making investment decisions for the Funds, but there is no guarantee that its decisions will produce the intended result. The successful use of hedging and risk management techniques may be adversely affected by imperfect correlation between movements in the price of the hedging vehicles and the securities being hedged.

Securities Lending Risk - Portfolio securities may be loaned to brokers, dealers and financial institutions to realize additional income under guidelines adopted by the Board of Trustees. A risk of lending portfolio securities, as with other extensions of credit, is the possible loss of rights in the collateral should the borrower fail financially. The Fund might not be able to recover the securities or their value. In determining whether to lend securities, the Adviser or its agent, will consider all relevant facts and circumstances, including the creditworthiness of the borrower.
