Optimum Large Cap Growth Fund

Objective

Optimum Large Cap Growth Fund seeks long-term growth of capital.

Strategy

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of large market capitalization companies (80% policy). This policy may be changed only upon 60 days’ prior notice to shareholders. For purposes of this Fund, large market capitalization companies are those companies whose market capitalization is similar to the market capitalization of companies in the Russell 1000® Growth Index. As of June 30, 2017, the Russell 1000 Growth Index had a market capitalization range between $1.8 billion and $749.7 billion. The market capitalization range for this index will change on a periodic basis. A company’s market capitalization is based on its current market capitalization or its market capitalization at the time of the Fund’s investment. Companies whose market capitalization no longer meets this definition after purchase continue to be considered to have a large capitalization for purposes of this 80% policy. Russell Investment Group is the source and owner of the trademarks, service marks, and copyrights related to the Russell Indexes. Russell® is a trademark of the Russell Investment Group.

The Fund intends to invest primarily in common stocks of US companies, but it may also invest in other securities that a sub-advisor believes provide opportunities for capital growth, 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 foreign securities, including American depositary receipts (ADRs) and other depositary receipts and shares; 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 T. Rowe Price Associates, Inc. (T. Rowe Price) and ClearBridge Investments LLC (ClearBridge) 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, T. Rowe Price normally invests in common stocks of a diversified group of growth companies. While it may invest in companies of any market capitalization, T. Rowe Price generally seeks investments in stocks of large-capitalization companies with one or more of the following characteristics: strong cash flow and an above-average rate of earnings growth; the ability to sustain earnings momentum during economic downturns; and occupation of a lucrative niche in the economy and ability to expand even during times of slow economic growth. T. Rowe Price believes that when a company increases its earnings faster than both inflation and the overall growth rate of the economy, the market will eventually reward it with a higher stock price. T. Rowe Price's portion of the Fund may at times invest significantly in technology stocks.

In pursuing its investment strategy, T. Rowe Price has the discretion to deviate from its normal investment criteria, as described above, and purchase securities that T. Rowe Price believes will provide an opportunity for substantial appreciation. These situations might arise when T. Rowe Price’s management believes a security could increase in value for a variety of reasons, including a change in management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive development. T. Rowe Price may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

In managing its portion of the Fund’s assets, ClearBridge normally invests in equity securities (or other instruments with similar economic characteristics) of US companies with large market capitalizations. ClearBridge’s core holdings are large capitalization companies that it believes to be dominant in their industries due to product, distribution or service strength.

ClearBridge emphasizes individual security selection while diversifying investments across industries, which may help to reduce risk. ClearBridge attempts to identify established, large capitalization companies with the highest growth potential. ClearBridge then analyzes each company in detail, ranking its management, strategy and competitive market position. Finally, ClearBridge attempts to identify the best values available among the growth companies identified. ClearBridge may sell a security if it no longer meets the Fund’s investment criteria or for other reasons, including to meet redemptions or to redeploy assets to better investment opportunities.

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 may be changed without shareholder approval. However, the Fund’s Board of Trustees 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.

Investing involves risk, including the possible loss of principal.

REIT investments are subject to many of the risks associated with direct real estate ownership, including changes in economic conditions, credit risk, and interest rate fluctuations. A REIT fund’s tax status as a regulated investment company could be jeopardized if it holds real estate directly, as a result of defaults, or receives rental income from real estate holdings.
