*We guarantee that we will credit interest for the life of the contract to amounts in the Interest Accumulation Account of our General Account at a rate at least equal to the greater of (1) any contractual minimum guarantee provided by the contract or (2) the minimum rate required by applicable state law or, if no state law minimum rate is applicable to a contract, the guaranteed minimum credited interest rate will be set pursuant to National Association of Insurance Commissioners (NAIC) standard nonforfeiture law. The NAIC minimum rate is determined in accordance with a formula and cannot be less than 0.15% or more than 3.00% in any event. We determine whether the application of the formula will change the minimum guaranteed rate each November, and any change is effective the following January 1 for that calendar year. The minimum rate for 2024 has been set at 2.85% or 3.00%, depending on contract as indicated above, in accordance with this formula. In addition, Mutual of America may credit interest to your contract amounts in the Interest Accumulation Account at a higher rate that we declare from time to time and which may increase or decrease at our sole discretion, although we are not obligated to credit interest in excess of the minimum guaranteed rate. If you have an existing contract, you should refer to it before making a decision because it may have a guaranteed minimum rate in excess of the formula described above and the advertised declared rate. We compound interest daily on your contract amounts in the Interest Accumulation Account to produce an effective annual yield that is equal to the stated interest rate.
