The Fund employs a passive management or indexing investment approach, through physical acquisition of securities, designed to track the performance of the index, a free float adjusted market capitalisation weighted index. In tracking the performance of the index, the Fund attempts to replicate the 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 index is a capitalisation weighted index of 500 U.S. stocks. The index is designed to measure performance of the broad domestic economy through changes in the aggregate market value of the 500 stocks representing all major industries.
