The Parent Index measures the performance of the largest 3000 U.S. equity securities with readily available price data. The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index. In seeking to track the performance of the Index, the Fund attempts to allocate investments among stocks in approximately the same weightings as the Index, beginning with the stocks that make up the larger portion of the Indexs value.
