The investment seeks to track the investment results (before fees and expenses) of the S&P Quality Developed ex-U.S. LargeMidCap Index (the underlying index). The fund will invest at least 90% of its total assets in securities that comprise the underlying index. The index provider compiles, maintains and calculates the underlying index, which is constructed from constituents of the S&P Developed ex-U.S. LargeMidCap Index that the index provider identifies as being of the highest quality-that is, stocks of companies that seek to generate higher revenue and cash flow than their counterparts through prudent use of assets and finances.
