Investing primarily in a combination of Fidelity® U.S. equity funds, international equity funds, bond funds, and short-term funds (underlying Fidelity® funds) to seek to achieve the fund's investment objective consistent with a payment strategy to be administered through a complementary systematic withdrawal plan. Allocating assets according to a neutral asset allocation strategy shown in the glide path below that adjusts over time until it reaches an allocation similar to that of the Fidelity Simplicity RMD Income FundSM, approximately 10 to 20 years after the year 2030. Fidelity Management & Research Company LLC (FMR) (the Adviser) may modify the fund's neutral asset allocations from time to time when in the interests of shareholders. The neutral asset allocation shown in the glide path depicts the allocation to U.S. equity funds, international equity funds, bond funds (including U.S. investment grade bond, international bond, short-term inflation-protected bond, long-term inflation-protected bond, and long-term treasury bond), and short-term funds. Buying and selling futures contracts (both long and short positions) in an effort to manage cash flows efficiently, remain fully invested, or facilitate asset allocation. The Adviser, under normal market conditions, will make investments that are consistent with seeking total return for several years beyond the fund's horizon date in an effort to achieve the fund's overall investment objective. As of August 1, 2024, the fund's neutral asset allocation to underlying Fidelity® funds and futures was approximately: U.S. Equity Funds 36% International Equity Funds 24% International Bond Funds 5% U.S. Investment Grade Bond Funds 26% Long-Term Treasury Bond Funds 5% Long-Term Inflation-Protected Bond Funds 5% Short-Term Inflation-Protected Bond Funds 0% Short-Term Funds 0%       * The Adviser may change these percentages over time. As a result of the active asset allocation strategy (discussed below), actual allocations may differ from the neutral allocations above. The allocation percentages may not add to 100% due to rounding. The Adviser, under normal market conditions, will use an active asset allocation strategy to increase or decrease asset class exposures relative to the neutral asset allocations reflected above by up to 10% for equity funds, bond funds and short-term funds to reflect the Adviser's market outlook, which is primarily focused on the intermediate term. The asset allocations in the glide path and pie chart above are referred to as neutral because they do not reflect any decisions made by the Adviser to overweight or underweight an asset class. The Adviser may also make active asset allocations within other asset classes (such as commodities, high yield debt (also referred to as junk bonds), floating rate debt, real estate debt, and emerging markets debt) from 0% to 10% of the fund's total assets individually, but no more than 25% in aggregate within those other asset classes. Such asset classes are not reflected in the neutral asset allocations reflected in the glide path and pie chart above. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics. Designed for investors approaching required minimum distribution (RMD) age and above who will turn age 70 in or within a few years of 2030 (horizon date) and plan to gradually withdraw the value of their account in the fund over time (in accordance with minimum distribution requirements as mandated by the Internal Revenue Code and related regulations). The fund's investment objective is intended to support a payment strategy designed to be implemented through a shareholder's voluntary participation in a complementary systematic withdrawal plan that will enable shareholders to receive regular payments from the fund based on their expected required minimum distributions from certain types of retirement accounts as mandated by the Internal Revenue Code. However, shareholders may invest in the fund and not participate in the plan. Investors should refer to the "Features and Policies" section of the prospectus for a summary of how the payment strategy and plan are designed to operate.
