The investment seeks to track the performance of a benchmark index. The fund employs an indexing investment approach designed to track the performance of the S&P Global ex-U.S. Property Index, a float-adjusted, market-capitalization-weighted index that measures the equity market performance of international real estate stocks in both developed and emerging markets. The index is composed of stocks of publicly traded equity real estate investment trusts (known as REITs) and certain real estate management and development companies (REMDs).
