Optimum International Fund

Objective

Optimum International Fund seeks long-term growth of capital. The Fund may also seek income.

Strategy

The Fund invests primarily in non-U.S. securities, including securities of issuers located in emerging markets, but, in any event, will invest at least 65% of its net assets in non-U.S. securities. The Fund considers non-U.S. securities to include those securities issued by companies: (i) whose principal securities trading markets are outside the U.S.; (ii) that derive 50% or more of their total revenue from either goods or services produced or sales made in markets outside the U.S.; (iii) that have 50% or more of their assets outside the U.S.; (iv) that are linked to non-U.S. dollar currencies; or (v) that are organized under the laws of, or with principal offices in, a country other than the U.S. The Fund does not limit its investments to issuers within a specific market capitalization range.

The Fund intends to invest primarily in common stocks, but it may also invest in other securities that the sub-advisors believe provide opportunities for capital growth and income, such as preferred stocks, warrants, and securities convertible into common stocks. In keeping with the Fund's investment objective, the Fund may also invest in futures, options, and other derivatives; and fixed income securities, including those rated below investment grade.

The Fund's manager, Delaware Management Company (Manager), has selected EARNEST Partners LLC (EARNEST) and Acadian Asset Management LLC (Acadian) to serve as the Fund's sub-advisors. Each sub-advisor is responsible for the day-to-day investment management of the portion of the Fund's assets that the Manager allocates to the sub-advisor. The Manager may change the allocation at any time. The relative values of each sub-advisor's share of the Fund's assets also may change over time. Each sub-advisor selects investments for its portion of the Fund based on the sub-advisor's own investment style and strategy.

In managing its portion of the Fund's assets, EARNEST normally employs a fundamental, bottom-up investment process. The first step in EARNEST’s investment process is to screen the relevant universe to identify stocks that it believes are likely to outperform based on their financial characteristics and the current environment. Using an approach called Return Pattern Recognition, EARNEST seeks to identify the financial and market characteristics that have been in place when an individual company has produced outstanding performance. These characteristics include valuation measures, market trends, operating trends, growth measures, and profitability measures. EARNEST screens companies and selects for an in-depth fundamental review those exhibiting the set of characteristics that it believes indicate outperformance. The screening process allows EARNEST to review the relative universe of companies and focus on those it considers the best prospects.

In managing its portion of the Fund's assets, Acadian utilizes a disciplined quantitative strategy to actively invest in non-U.S. developed and emerging markets equity strategies. All stocks in the non-U.S. equity universe are evaluated across multiple quantitative factors. Acadian’s quantitative investment process builds portfolios from the bottom up, using proprietary valuation models that measure approximately 20 stock factors, focusing on those that have proven most effective in predicting returns. The result is a rating of all securities in the Acadian database in terms of each stock’s expected return. A portfolio optimization program is used to balance the expected return on the stocks with factors such as company, country, or industry weightings of the Fund’s benchmark index; desired level of risk; estimated transaction costs; available liquidity; and other requirements.

In response to market, economic, political, or other conditions, a sub-advisor may temporarily use a different investment strategy for defensive purposes. If a sub-advisor does so, different factors could affect the Fund's performance and the Fund may not achieve its investment objective. The Fund's investment objective is nonfundamental and can be changed without shareholder approval. However, the Fund's Board of Trustees (Board) must approve any changes to nonfundamental investment objectives, and the Fund's shareholders would be given at least 60 days' notice prior to any such change.

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 and, if available, its summary prospectus, which may be obtained by visiting the fund literature page 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 U.S. 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.

Fixed income securities and bond funds can lose value, and investors can lose principal, as interest rates rise. They also may be affected by economic conditions that hinder an issuer’s ability to make interest and principal payments on its debt.

The Fund may also be subject to prepayment risk, the risk that the principal of a fixed income security that is held by the Fund may be prepaid prior to maturity, potentially forcing the Fund to reinvest that money at a lower interest rate.

High yielding, noninvestment grade bonds (junk bonds) involve higher risk than investment grade bonds.

The high yield secondary market is particularly susceptible to liquidity problems when institutional investors, such as mutual funds and certain other financial institutions, temporarily stop buying bonds for regulatory, financial, or other reasons. In addition, a less liquid secondary market makes it more difficult for the Fund to obtain precise valuations of the high yield securities in its portfolio.

The Funds 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 derivative transaction depends upon the counterparties’ ability to fulfill their contractual obligations.

Liquidity risk is the possibility that securities cannot be readily sold within seven days at approximately the price at which a fund has valued them.
