The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted.

Total returns may reflect waivers and/or expense reimbursements by the manager and/or distributor for some or all of the periods shown. Performance would have been lower without such waivers and reimbursements.

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.

Investing involves risk, including the possible loss of principal.

International investments entail risks not ordinarily associated with US investments including fluctuation in currency values, differences in accounting principles, or economic or political instability in other nations.

Investing in emerging markets can be riskier than investing in established foreign markets due to increased volatility and lower trading volume.

The Fund may invest in derivatives, which may involve additional expenses and are subject to risk, including the risk that an underlying security or securities index moves in the opposite direction from what the portfolio manager anticipated. A derivatives transaction depends upon the counterparties’ ability to fulfill their contractual obligations.

The disruptions caused by natural disasters, pandemics, or similar events could prevent the Fund from executing advantageous investment decisions in a timely manner and could negatively impact the Fund’s ability to achieve its investment objective and the value of the Fund’s investments.
