The availability of certain sales charge waivers and discounts may depend on whether you purchase your shares directly from the Fund or through an intermediary.

In all instances, it is the purchaser’s responsibility to notify the Fund or the purchaser’s intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares directly from the Fund or through another intermediary to receive these waivers or discounts.

Effective August 21, 2017, the following information replaces similar information found in the "Fund Services" section under the "Fund Distribution" heading.

Combined Purchase. To receive a Class A or Class M front-end sales charge reduction, if you are a new shareholder, you may combine your purchase of Class A or Class M shares with purchases of: (i) Class A, Class M, and Class C shares of any Fidelity^® fund that offers Advisor classes of shares, (ii) Advisor C Class shares of Fidelity^® Treasury Money Market Fund, and (iii) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor^® 529 Plan. Purchases may be aggregated across multiple intermediaries on the same day for the purpose of qualifying for the Combined Purchase program.

Rights of Accumulation. To receive a Class A or Class M front-end sales charge reduction, if you are an existing shareholder, you may add to your purchase of Class A or Class M shares the current value of your holdings in: (i) Class A, Class M, and Class C shares of any Fidelity^® fund that offers Advisor classes of shares, (ii) Advisor C Class shares of Fidelity^® Treasury Money Market Fund, (iii) Daily Money Class shares of a fund that offers Daily Money Class shares acquired by exchange from any Fidelity^® fund that offers Advisor classes of shares, (iv) Class O shares of Fidelity Advisor^® Diversified Stock Fund and Fidelity Advisor^® Capital Development Fund, and (v) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor^® 529 Plan. The current value of your holdings is determined at the NAV at the close of business on the day prior to your purchase of Class A or Class M shares. The current value of your holdings will be added to your purchase of Class A or Class M shares for the purpose of qualifying for the Rights of Accumulation program. Purchases and holdings may be aggregated across multiple intermediaries for the purpose of qualifying for the Rights of Accumulation program.

Letter of Intent. You may receive a Class A or Class M front-end sales charge reduction on your purchases of Class A and Class M shares made during a 13-month period by signing a Letter of Intent (Letter). File your Letter with Fidelity no later than the date of the initial purchase toward completing your Letter. Each Class A or Class M purchase you make toward completing your Letter will be entitled to the reduced front-end sales charge applicable to the total investment indicated in the Letter. Purchases of the following may be aggregated for the purpose of completing your Letter: (i) Class A and Class M shares of any Fidelity^® fund that offers Advisor classes of shares (except those acquired by exchange from Daily Money Class shares of a fund that offers Daily Money Class shares that had been previously exchanged from a Fidelity^® fund that offers Advisor classes of shares), (ii) Class C shares of any Fidelity^® fund that offers Advisor classes of shares, (iii) Advisor C Class shares of Fidelity^® Treasury Money Market Fund, and (iv) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor^® 529 Plan. Reinvested income and capital gain distributions will not be considered purchases for the purpose of completing your Letter. Purchases may be aggregated across multiple intermediaries for the purpose of qualifying for the Letter of Intent program. Your initial purchase toward completing your Letter must be at least 5% of the total investment specified in your Letter. Fidelity will register Class A or Class M shares equal to 5% of the total investment specified in your Letter in your name and will hold those shares in escrow. You will earn income, dividends and capital gain distributions on escrowed Class A and Class M shares. The escrow will be released when you complete your Letter. You are not obligated to complete your Letter. If you do not complete your Letter, you must pay the increased front-end sales charges due in accordance with the sales charge schedule in effect when your shares were originally bought. Fidelity may redeem sufficient escrowed Class A or Class M shares to pay any applicable front-end sales charges. If you purchase more than the amount specified in your Letter and qualify for additional Class A or Class M front-end sales charge reductions, the front-end sales charge will be adjusted to reflect your total purchase at the end of 13 months and the surplus amount will be applied to your purchase of additional Class A or Class M shares at the then-current offering price applicable to the total investment.
