MoA Mid Cap Equity Index Fund (Mutual of America Mid-Cap Equit) Fonds

The fund invests primarily in the 400 common stocks included in the S&P MidCap 400® Index to replicate, to the extent practicable and cost effective, the weightings of such stocks in the index. The components of the index are market capitalization weighted, adjusted for free float, which is the value of shares readily available in the market as held by public investors. Under normal circumstances, at least 80% of the fund's total assets are invested in securities included in the S&P 400® Index.
