Diversification

The fund may not with respect to 75% of the fund's total assets, purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities, or securities of other investment companies) if, as a result, (a) more than 5% of the fund's total assets would be invested in the securities of that issuer, or (b) the fund would hold more than 10% of the outstanding voting securities of that issuer.

Effective October 1, 2015, the following information has been removed from the "Investment Policies and Limitations" section on page 4.

Diversification

In order to qualify as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986, as amended, the fund currently intends to comply with certain diversification limits imposed by Subchapter M.

Subchapter M generally requires the fund to invest no more than 25% of its total assets in securities of any one issuer and to invest at least 50% of its total assets so that (a) no more than 5% of the fund's total assets are invested in securities of any one issuer, and (b) the fund does not hold more than 10% of the outstanding voting securities of that issuer. However, Subchapter M allows unlimited investments in cash, cash items, government securities (as defined in Subchapter M) and securities of other regulated investment companies. These tax requirements are generally applied at the end of each quarter of the fund's taxable year.

Effective April 1, 2015, following an internal corporate reorganization, FMR Investment Management (U.K.) Limited is carrying on the business of Fidelity Management & Research (U.K.) Inc. The following information replaces similar information found in the "Control of Investment Advisers" section beginning on page 48.

FMR LLC, as successor by merger to FMR Corp., is the ultimate parent company of FMR, FIMM, FMR Investment Management (U.K.) Limited (FMR U.K.), Fidelity Management & Research (Hong Kong) Limited (FMR H.K.), Fidelity Management & Research (Japan) Limited (FMR Japan), and FMRC. The voting common shares of FMR LLC are divided into two series. Series B is held predominantly by members of the Abigail P. Johnson family, directly or through trusts, and is entitled to 49% of the vote on any matter acted upon by the voting common shares. Series A is held predominantly by non-Johnson family member employees of FMR LLC and its affiliates and is entitled to 51% of the vote on any such matter. The Johnson family group and all other Series B shareholders have entered into a shareholders' voting agreement under which all Series B shares will be voted in accordance with the majority vote of Series B shares. Under the 1940 Act, control of a company is presumed where one individual or group of individuals owns more than 25% of the voting securities of that company. Therefore, through their ownership of voting common shares and the execution of the shareholders' voting agreement, members of the Johnson family may be deemed, under the 1940 Act, to form a controlling group with respect to FMR LLC.
