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 MSCI US Investable Market Index (IMI)/Telecommunication Services 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the telecommunication services sector, as classified under the Global Industry Classification Standard. 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. The fund is non-diversified.
