Mutual of America's annual Separate Account fees on IRA Separate Account balances have been reduced
from 1.20% to 0.90%. In addition, the underlying funds incur annual expenses (including management fees and other expenses) that range
from 0.16% to 0.99%.
The target date set forth in each Retirement Fund's name is the approximate date that the fund expects investors to retire
and begin withdrawing their account balance. The value of a Retirement Fund is not guaranteed at any time, including at and after the
target date. There is no guarantee that a Retirement Fund will correctly predict market or economic conditions, and as with other mutual
fund investments, you could lose money. In addition to a retirement date, individuals should consider their risk tolerance, time horizon,
personal circumstances and complete financial situation before investing.

Total IRA account balance is determined by aggregating all amounts in the Interest Accumulation Account of our General
Account and in the Separate Account investment funds for all IRA contracts (except SEP and SIMPLE IRAs) held by the same person.
Interest rate applies only to balances allocated to the Interest Accumulation Account.
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 1.00% 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 current minimum rate has been set at 1.00% in accordance with this formula. In
addition, Mutual of America may credit interest to your contract amounts in the General 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 General Account to produce an effective annual yield that is equal to the stated interest rate.
STAR RATING KEY
The Morningstar Rating™ for funds, or "star rating," is calculated for managed products (including mutual funds, variable
annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year
history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It
is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly
excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products
in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive
2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average
of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights
are: 100% three-year rating for 36–59 months of total returns, 60% five-year rating/40% three-year rating for 60–119
months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns.
While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year
period actually has the greatest impact because it is included in all three rating periods.
