The Fund employs an indexing investment approach designed to track the performance of the CRSP US Large Cap Growth Index (the Index), a broadly diversified index predominantly made up of growth stocks of large U.S. companies. The Fund 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 may become non-diversified, as defined under the Investment Company Act of 1940, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Index.
