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 stable neutral asset allocation strategy (approximately 11% in U.S. equity funds, 8% in international equity funds, 43% in U.S. investment grade bond funds, 5% in international bond funds, 3% in long-term treasury bond funds, 20% in short-term inflation-protected bond funds, and 10% in short-term funds). 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. 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. Allocating assets among underlying Fidelity® funds and futures according to a stable neutral asset allocation of approximately: U.S. Equity Funds 11% International Equity Funds 8% International Bond Funds 5% U.S. Investment Grade Bond Funds 43% Long-Term Treasury Bond Funds 3% Long-Term Inflation-Protected Bond Funds 0% Short-Term Inflation-Protected Bond Funds 20% Short-Term Funds 10%       * 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 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 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. 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. Proposed Reorganization.
