Investing involves risk, including the possible loss of principal.

Carefully consider the Fund’s investment objectives, risk factors, charges, and expenses before investing. This and other information can be found in the Fund’s prospectus, which may be obtained by visiting optimummutualfunds.com/literature or calling 800 914-0278. Investors should read the prospectus and, if available, the summary prospectus carefully before investing.

Investments in derivatives may involve additional expenses and are subject to significant loss if they perform differently than anticipated. Derivatives are also subject to the risk that the counterparty may fail to perform its obligations.

Fixed income securities can lose value, including the possible loss of principal. Fixed income securities are subject to credit risk and interest rate risk. Credit risk is the risk that an issuer of a fixed income security may be unable to make interest payments and/or repay principal in a timely manner. Interest rate risk is the risk that prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes.

High yield securities (“junk bonds”) are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of income and principal than higher-rated securities.

Mortgage-backed securities (MBS) and asset-backed securities (ABS) are subject to credit risk and interest rate risk and may also be subject to prepayment risk and extension risk. In addition, MBS and ABS may decline in value, become more volatile, face difficulties in valuation, or experience reduced liquidity due to changes in interest rates or general economic conditions. Certain MBS, such as collateralized mortgage obligations, real estate mortgage investment conduits, and stripped MBS may be more susceptible to these risks than other MBS.

Diversification may not protect against market risk.
