The following information replaces similar information found in the "Distribution Services" section on page 37.

FDC or an affiliate may compensate, or upon direction make payments for certain retirement plan expenses to, intermediaries, including retirement plan sponsors, administrators, and service-providers (including affiliates of FDC). A number of factors are considered in determining whether to pay these additional amounts. Such factors may include, without limitation, the level or type of services provided by the intermediary, the level or expected level of assets or sales of shares, and other factors. In addition to such payments, FDC or an affiliate may offer other incentives such as sponsorship of educational or client seminars relating to current products and issues, payments or reimbursements for travel and related expenses associated with due diligence trips that an intermediary may undertake in order to explore possible business relationships with affiliates of FDC, and/or payments of costs and expenses associated with attendance at seminars, including travel, lodging, entertainment, and meals. Certain of the payments described above may be significant to an intermediary. As permitted by SEC and Financial Industry Regulatory Authority rules and other applicable laws and regulations, FDC or an affiliate may pay or allow other incentives or payments to intermediaries.

The fund's transfer agent or an affiliate may also make payments and reimbursements from its own resources to certain intermediaries (who may be affiliated with the transfer agent) for providing recordkeeping and administrative services to plan participants or for providing other services to retirement plans. Please see "Transfer and Service Agent Agreements" in this SAI for more information.

FDC or an affiliate may also make payments to banks, broker-dealers and other service-providers (who may be affiliated with FDC) for distribution-related activities and/or shareholder services. If you have purchased shares of the fund through an investment professional, please speak with your investment professional to learn more about any payments his or her firm may receive from FMR, FDC, and/or their affiliates, as well as fees and/or commissions the investment professional charges. You should also consult disclosures made by your investment professional at the time of purchase.

Any of the payments described in this section may represent a premium over payments made by other fund families. Investment professionals may have an added incentive to sell or recommend a fund over others offered by competing fund families, or retirement plan sponsors may take these payments into account when deciding whether to include a fund as a plan investment option.
