The Fund is an actively managed exchange-traded fund (ETF) that seeks to achieve its investment objective by investing in publicly-traded real estate investment trusts (REITs) that derive their revenue from ownership and/or management of residential properties. Under normal circumstances, the Fund will invest at least 80 percent of its net assets (plus any borrowings for investment purposes) in Residential REITs. The remainder of the Funds net assets (plus any borrowings for investment purposes) typically will be invested in U.S. real estate-related securities that are traded on a U.S. exchange (Real Estate-Related Securities). Real Estate-Related Securities may include preferred, common or convertible securities (including warrants) issued by builders or other real estate development or management companies, Residential REITs that receive less than 75 percent of their income from the categories specified to meet the definition for Residential REITs, as well as REITs with student housing, manufactured housing, self-storage, and mortgages or any debt securities from these issuers, or backed by residential real estate. The Fund may also invest in ETFs predominantly investing in Real Estate-Related Securities and other securities or derivatives related to U.S. real estate, specifically swap agreements and options.
