Money Market Fund Investors: You could lose money by investing in the Fund. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The Fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund's liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

The total return figures for periods extending beyond a year are average rates of return and do not reflect the Funds' actual year-to-year results, which varied over the periods shown. Contributions or withdrawals made within a period would experience different rates of return based on the unit values on the dates of such transactions.

²The transfer agent and distributor for the Fidelity VIP Portfolios and the investment advisers for the PIMCO Variable Insurance Trust Real Return Portfolio, the T. Rowe Price Blue Chip Growth Portfolio, MFS^® VIT Mid Cap Value Portfolio, and the Victory RS Small Cap Grown Equity VIP Series reimburse Mutual of America Life Insurance Company for certain administrative expenses or services Mutual of America provides. We pass these reimbursements on to our contract holders, and as such, the Separate Account expenses for the corresponding Separate Account Funds are reduced to the extent Mutual of America receives such reimbursements. Without such reimbursements, the performance returns of the corresponding Separate Account Funds would have been lower. Please refer to the prospectuses of these Underlying Funds for more information on such expense reimbursements.
