To pursue its goal, the fund generally invests in securities that are included in the Dow Jones Equity All REIT Capped Index. The index is a float-adjusted market capitalization weighted index that is subject to capping constraints at each quarterly rebalancing. The index generally includes all publicly traded equity real estate investment trusts (REITs) with a minimum float-adjusted market capitalization of $200 million and a three-month median daily value traded of at least $5 million. A security becomes ineligible if its float-adjusted market capitalization falls below $100 million for two consecutive quarters
