BMO S&P 500 Index 

The fund captures the US equity large-cap space by tracking a well-known indexthe S&P 500, which covers approximately 80% of available market capitalization. The fund defines large-caps as the S&P Committee sees it, which means it includes a fairly large allocation to firms that may be considered midcaps. Stocks are market-cap-weighted, with a consideration on sector balance by comparing the weight of each GICS (Global Industry Classification Standard) sector in the underlying index to its weight in the relevant market capitalization range of the S&P Total Market Index (parent index). The index is rebalanced on a quarterly basis.
