  • Investments in stocks and bonds are subject to risks, including stock market and interest rate fluctuations. Investments ingrowth stocks as well as small and mid-cap company stocks may be subject to volatile price swings and therefore present agreater potential for loss than other investments. Investments in non-U.S. stocks and bonds are subject to additional riskssuch as fluctuations in foreign currencies, political and economic instability, differences in securities regulation andaccounting standards, foreign tax laws, and limited availability of public information. Income seeking investment strategiesmay not be realized due to changes in dividend policies or the availability of capital resources.

    Investments that concentrate on one economic sector or geographic region are generally subject to greater volatility thanmore diverse investments. Investments in real estate investment trusts (REITs) involve risks such as refinancing, economicconditions in the real estate industry, changes in property values, dependency on real estate management, and other risksassociated with a concentration in one sector or geographic region. Investments in securities related to gold and otherprecious metals and minerals are speculative and impacted by a host of worldwide economic, financial and political factors.

    Investments in debt securities are subject to credit risk (i.e., the risk that an issuer might not pay interest when due or repayprincipal at maturity of the obligation). Investments in lower-rated bonds and “junk bonds” are considered speculative dueto the heightened risk of default and are subject to unpredictable losses as a result of changes in the issuer’s creditworthiness.

    Investments in derivatives are subject to heightened risk; gains or losses from non-hedging positions may be substantiallygreater than the cost of the position. Active trading may result in high portfolio turnover and correspondingly greatertransaction costs for the portfolio and underlying portfolios.

    There can be no assurance that the Portfolios will meet their investment objectives. A full description of the investment goals,principal strategies, and risks for each Portfolio are provided in the prospectus.

    Investments are not guaranteed or endorsed by any bank, is not a deposit or obligation of any bank, and is not federallyinsured by Federal Deposit Corporation (FDIC), the Federal Reserve Board or any other federal government agency.

  • SUNAMERICA SERIES TRUSTEXPENSE EXAMPLE January 31, 2020

    (unaudited)Disclosure of Portfolio Expenses in Shareholder Reports

    As a shareholder of a separate series (a “Portfolio”) in SunAmerica Series Trust (the “Trust”), you incurongoing costs, including management fees, or service (12b-1) fees, and other expenses. The Example is intendedto help you understand your ongoing costs (in dollars) of investing in the Portfolios and to compare these costswith the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000invested at August 1, 2019 and held until January 31, 2020. Shares of the Trust are not offered directly to thepublic. Instead, shares are currently issued and redeemed only in connection with investments in andpayments under variable annuity contracts and variable life insurance policies (“Variable Contracts”) offeredby life insurance companies affiliated with SunAmerica Asset Management, LLC, the Trust’s investmentadviser and manager. The fees and expenses associated with the Variable Contracts are not included in theseExamples, and had such fees and expenses been included your costs would have been higher. Please see yourvariable contract prospectus for more details on the fees associated with the variable contract.

    Actual Expenses

    The “Actual” section of the table provides information about your actual account values and actual expenses.You may use the information in these columns, together with the amount you invested, to estimate theexpenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600account value divided by $1,000 = 8.6), then multiply the result by the number in the column under theheading entitled “Expenses Paid During The Period Ended January 31, 2020” to estimate the expenses you paidon your account during this period. The “Expenses Paid During The Period Ended January 31, 2020” columnand the “Annualized Expense Ratio” column do not include fees and expenses that may be charged by theVariable Contracts, in which the Portfolios are offered. Had these fees and expenses been included, the“Expenses Paid During The Period Ended January 31, 2020” column would have been higher and the “EndingAccount Value” column would have been lower.

    Hypothetical Example for Comparison Purposes

    The “Hypothetical” section of the table provides information about hypothetical account values andhypothetical expenses based on the Portfolio’s actual expense ratio and an annual rate of return of 5% beforeexpenses, which is not the Portfolio’s actual return. The hypothetical account values and expenses may not beused to estimate the actual ending account balance or expenses you paid for the period. You may use thisinformation to compare the ongoing costs of investing in the Portfolios and other funds. To do so, compare this5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of otherfunds. The “Expenses Paid During The Period Ended January 31, 2020” column and the “Annualized ExpenseRatio” column do not include fees and expenses that may be charged by the Variable Contracts, in which thePortfolios are offered. Had these fees and expenses been included, the “Expenses Paid During The PeriodEnded January 31, 2020” would have been higher and the “Ending Account Value” would have been lower.

    Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do notreflect any fees and expenses that may be charged by the Variable Contracts. Please refer to your variablecontract prospectus for more information. Therefore, the “Hypothetical” example is useful in comparingongoing costs and will not help you determine the relative total costs of owning different funds. In addition, ifthese fees and expenses were included, your costs would have been higher.

    @ See Note 1 in Notes to Financial Statements* Expenses are equal to the Portfolio’s annualized expense ratio multiplied by the average account value over the period, multiplied by 184 days

    divided by 365 days (to reflect the one-half year period) except for SA Franklin U.S. Equity Smart Beta Portfolio, “Actual Return” Informationwhich were multiplied by 116 days divided by 365 days. These ratios do not reflect expenses associated with the Variable Contracts. If such feesand expenses had been included, the expenses would have been higher. Please refer to your Variable Contract prospectus for details on theexpenses that apply to the Variable Contracts of the insurance companies.

    # During the stated period, the investment adviser either waived fees or reimbursed expenses for the Portfolios or through recoupmentprovisions, recovered a portion of or all fees and expenses waived or reimbursed in the previous two fiscal years. As a result, if these fees andexpenses had not been waived, the “Actual/Hypothetical Ending Account Value” would have been lower and the “Actual/HypotheticalExpenses Paid During the Period Ended January 31, 2020” and “Annualized Expense Ratios” would have been higher. If these fees and expenseshad not been recouped, the “Actual/Hypothetical Ending Account Value” would have been higher and the “Actual/Hypothetical ExpensesPaid During the Period Ended January 31, 2020” and the “Annualized Expense Ratio” would have been lower.
