A company is engaged in the development, operation, and/or management of infrastructure assets if, in the opinion of Delaware Management Company, the Funds investment adviser (Manager), the company (i) derives at least 50% of its revenue or profits, either directly or indirectly, from infrastructure assets, or (ii) commits at least 50% of its assets to activities related to infrastructure assets. The Fund will invest principally in exchange-listed equity securities of companies that are located throughout the world, including the United States. The Fund will rely on the country where the issuer is incorporated, is headquartered or has its principal place of business in determining the location of an issuer. The Fund may also invest in exchange-listed equity securities of non-U.S. companies located in emerging market countries. Emerging market countries include those currently considered to be developing by the World Bank, the United Nations, or the countries governments. The Fund will primarily invest in emerging markets securities of countries included in the MSCI Emerging Markets Index. The Fund may invest in companies of any size; however, the Manager may exclude companies below a market capitalization of $2 billion that it deems not sufficiently liquid and may exclude large capitalization companies that the Manager believes have limited free float (i.e., shares of the company available to the public). The Manager uses a research-oriented, bottom-up (researching individual issuers) investment approach to seek to identify attractive global listed infrastructure companies. The Manager considers a number of factors in selecting individual investments for the Funds portfolio, including proprietary valuation analysis, company management due diligence and a risk assessment of each potential investment . Generally, in determining whether to sell a security, the Manager uses the same type of analysis that it uses when buying securities to determine whether the security continues to be a desired investment for the Fund, including consideration of the securitys current valuation. Additionally, the Manager may sell a security to reduce the Funds holding in that security, to take advantage of what it believes are more attractive investment opportunities or to raise cash. The Manager may permit its affiliate, Macquarie Investment Management Global Limited ( MIMGL ), to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL. Quantitative support from MIMGL may include portfolio analytics and research and other quantitative analysis relating to the Funds holdings and investment strategy. The Funds 80% policy is non-fundamental and may be changed without shareholder approval. However, Fund shareholders would be given at least 60 days notice prior to any such change. Show less
