Important Information Regarding the Mutual of America Money Market Fund

Historically low interest rates continue to adversely impact the performance of all money market funds. As a result, the fees and expenses related to the Mutual of America Investment Corporation Money Market Fund, as detailed in the most recent prospectus, together with Separate Account charges, may exceed the Fund's overall returns, resulting in negative net returns and the loss of principal over time. You should review the Separate Account charges applicable to your investments in the Separate Account to determine whether your investment in the Money Market Fund is providing a negative net return.

If you are not satisfied with your returns on your investment in the Money Market Fund, you may wish to consider Mutual of America's Interest Accumulation Account, to which we credit a fixed rate of interest (which may change at our discretion) that cannot go below the minimum guaranteed credited interest rate in effect during each calendar year. Amounts allocated to the Interest Accumulation Account, and credited interest, are not reduced by expenses and are guaranteed by Mutual of America (subject to our financial strength and claims-paying ability). Any decision regarding your investment in the Mutual of America Money Market Fund should be made based on your individual circumstances and needs.
