Allocating assets according to a stable neutral asset allocation strategy (approximately 11% in domestic equity funds, 8% in international equity funds, 46% in investment grade bond funds, 3% in long-term treasury bond funds, 10% in inflation-protected bond funds, and 23% in 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. Allocating assets among underlying Fidelity® funds and futures according to a stable neutral asset allocation of approximately:     Domestic Equity Funds 11%     International Equity Funds 8%     Investment Grade Bond Funds 46%     Long-Term Treasury Bond Funds 3%     Inflation-Protected Bond Funds 10%     Short-Term Funds 23% * 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, international 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.
