The investment seeks to track the performance of a benchmark index that measures the investment return of stocks of companies located in developed and emerging markets outside of the United States. The fund employs an indexing investment approach designed to track the performance of the FTSE All-World ex US Index, a free-float-adjusted, market-capitalization-weighted index designed to measure equity market performance of international markets. It attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the index, holding each stock in approximately the same proportion as its weighting in the index.
