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.

Senior Bank Loans Risk - Senior Loans are subject to the risk that a court could subordinate a Senior Loan, which typically holds the most senior position in the issuer’s capital structure, to presently existing or future indebtedness or take other action detrimental to the holders of Senior Loans. Senior Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. In the event of a default, a Fund may have difficulty collecting on any collateral. In addition, any collateral may be found invalid or may be used to pay other outstanding obligations of the borrower. A Fund’s access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized Senior Loan may not be fully collateralized and can decline significantly in value. Transactions in many senior loans settle on a delayed basis. As a result, sale proceeds related to the sale of such loans may not be available to make additional investments or to meet a Fund’s redemption obligation until potentially a substantial period of time after the sale of the loans. No active trading market may exist for some senior loans, which may impact the ability of a Fund to realize full value in some actively traded senior loans. Senior loans also may be subject to restriction on resale, which can delay the sale and adversely impact the sale price. Difficulty in selling a loan can result in a loss. Senior loans made to finance highly leveraged corporate acquisitions may be especially vulnerable to adverse changes in economic or market conditions. The market prices of floating rate loans are generally less sensitive to interest rate changes than are the market prices for securities with fixed interest rates. Certain senior loans may not be considered “securities,” and purchasers, such as a Fund, therefore may not be entitled to rely on the strong anti-fraud protections of the federal securities laws.

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.

Risks Associated with the Discontinuation of the London Interbank Offered Rate (“LIBOR”) - The Fund invests significantly in floating rate loans that have interest rate provisions linked to LIBOR. LIBOR is used extensively in the U.S. and globally as a “benchmark” or “reference rate” for such loans. It is expected that a number of private-sector banks currently reporting information used to set LIBOR will stop doing so after 2021 when their current reporting commitment ends, which could either cause LIBOR to stop publication immediately or cause LIBOR’s regulator to determine that its quality has degraded to the degree that it is no longer representative of its underlying market. The expected discontinuation of LIBOR may impact the functioning, liquidity, and value of these investments. The extent of this impact will depend on the specific loans, as well as the terms of those loans. Many loans have interest rate provisions referencing LIBOR that, when drafted, did not contemplate the permanent discontinuation of LIBOR and, as a result, there may be uncertainty or disagreement over how the loans should be interpreted. For example, loans without fallback language, or with fallback language that does not contemplate the discontinuation of LIBOR, could become less liquid and/or change in value as the date approaches when LIBOR will no longer be updated. Further, the interest rate provisions of these loans may need to be renegotiated. Finally, there may be other risks related to the discontinuation of LIBOR, such as loan price volatility risk and technology or systems risk. Currently, the U.S. and other countries are working to replace LIBOR with alternative reference rates. The alternative reference rates may be more volatile than LIBOR and may perform erratically until widely accepted within the marketplace. The risks associated with this discontinuation and transition will persist if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely matter.

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.

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.

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.

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.

Foreign Investing Risk - Investing in foreign companies or ETFs which invest in foreign companies, may involve more risks than investing in U.S. companies. These risks can increase the potential for losses in the Fund and may include, among others, currency devaluations, currency risks (fluctuations in currency exchange rates), country risks (political, diplomatic, regional conflicts, terrorism, war, social and economic instability and policies that have the effect of limiting or restricting foreign investment or the movement of assets), different trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility. Additionally, investments in securities denominated in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar. A decline in the value of foreign currencies relative to the U.S. dollar will reduce the value of securities held by the Fund and denominated in those currencies.

Derivatives Risk - Derivatives are used to limit risk in the Fund or to enhance investment return and have a return tied to a formula based upon an interest rate, index, price of a security, currency exchange rate or other measurement. Derivatives involve special risks, including: (1) the risk that interest rates, securities prices and currency markets will not move in the direction that a portfolio manager anticipates; (2) imperfect correlation between the price of derivative instruments and movements in the prices of the securities, interest rates or currencies being hedged; (3) the fact that skills needed to use these strategies are different than those needed to select portfolio securities; (4) the possible absence of a liquid secondary market for any particular instrument and possible exchange imposed price fluctuation limits, either of which may make it difficult or impossible to close out a position when desired; (5) the risk that adverse price movements in an instrument can result in a loss substantially greater than the Fund’s initial investment in that instrument (in some cases, the potential loss is unlimited); (6) particularly in the case of privately-negotiated instruments, the risk that the counterparty will not perform its obligations, or that penalties could be incurred for positions held less than the required minimum holding period; and (7) the inability to close out certain hedged positions to avoid adverse tax consequences. In addition, the use of derivatives for non-hedging purposes (that is, to seek to increase total return) is considered a speculative practice and may present an even greater risk of loss than when used for hedging purposes. Swap agreements are two-party contracts entered into for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which can be adjusted for an interest factor. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. When a Sub-Adviser uses margin, leverage, short sales or financial derivatives, such as options, futures and forward contracts, an investment in the Fund may be more volatile than investments in other mutual funds. Derivatives may also be embedded in securities such convertibles which typically include a call option on the issuer’s common stock. Although the intention is to use such derivatives to minimize risk to the Fund, as well as for speculative purposes, there is the possibility that derivative strategies will not be used or that ineffective implementation of derivative strategies or unusual market conditions could result in significant losses to the Fund. Over the counter derivatives, such as swaps, are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.

Leveraging Risk - The Fund’s use of leverage through futures, options, short positions, or inverse ETFs will magnify the Fund’s gains or losses. Futures require relatively small cash investment to control large amounts of derivatives, which magnifies gains and losses to the Fund. Leveraging the Fund creates an opportunity for increased returns but, at the same time, creates special risk considerations. For example, leveraging may exaggerate changes in the net asset value of the Fund’s shares and in the yield on the Fund’s portfolio.

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.
