In connection therewith, the following replaces the information in the section of the Fund’s Prospectus entitled “Fund summary — What are the Fund’s principal investment strategies?”: The Fund invests primarily in investments of small companies whose stock prices, in the portfolio managers’ opinion, appear low relative to their underlying value or future potential. Among other factors, the Fund’s investment manager, Delaware Management Company (Manager), considers the financial strength of a company, its management, the prospects for its industry, and any anticipated changes within the company that might suggest a more favorable outlook going forward. The Manager focuses on free cash flow in its individual stock selection, seeking companies that it believes have a sustainable ability to buy back shares, lower debt, and/or increase or initiate dividends. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be in investments of small-capitalization companies (80% policy). The Fund considers small-capitalization companies to be companies with a market capitalization generally less than 3.5 times the dollar-weighted, median market capitalization of the Russell 2000® Index at the time of purchase. The Fund may invest up to 15% of its net assets in real estate investment trusts (REITs). The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited, to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL. The Fund’s 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days’ notice prior to any such change. The following information is added into the section of the Fund’s Prospectus entitled “Fund summary — Who manages the Fund?”: Sub-advisors Macquarie Investment Management Global Limited Macquarie Funds Management Hong Kong Limited The following replaces the information in the section of the Fund's Prospectus entitled "How we manage the Fund — Our principal investment strategies”: The Manager researches individual companies and analyzes economic and market conditions, seeking to identify the securities or market sectors that it believes are the best investments for the Fund. The following are descriptions of how the portfolio management team pursues the Fund’s investment objective. The Manager strives to identify small companies that it believes offer above-average opportunities for long-term price appreciation because their current stock prices do not appear to accurately reflect the companies’ underlying value or future earnings potential. The Manager’s focus will be on value stocks, defined as stocks whose prices are historically low based on a given financial measure such as profit, book value, or cash flow. Companies may be undervalued for many reasons. They may be unknown to stock analysts, they may have experienced poor earnings, or their industry may be in the midst of a period of weak growth. The Manager will carefully evaluate the financial strength of a company, the nature of its management, any developments affecting the company or its industry, anticipated new products or services, possible management changes, projected takeovers, or technological breakthroughs. Using this extensive analysis, the Manager’s goal is to pinpoint the companies within the universe of undervalued stocks, whose true value is likely to be recognized and rewarded with a rising stock price in the future. Because there is added risk when investing in smaller companies, which may still be in their early developmental stages, the portfolio managers seek to maintain a well-diversified portfolio, typically holding a mix of different stocks, representing a wide array of industries. The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited, to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL. The Fund’s investment objective is nonfundamental. This means that the Fund’s Board of Trustees (Board) may change the objective without obtaining shareholder approval. If the objective were changed, the Fund would notify shareholders at least 60 days before the change became effective.
