The Morningstar Category Average is the average return for the peer group based on the returns of each individual fund within the group. It assumes reinvestment of dividends and capital gains, if any, and excludes sales charges.

Morningstar Category Average Gross Expense Ratio: This figure is calculated by Morningstar and represents the mean average of the gross expense ratio paid by each fund in the Morningstar category. Each share class of a fund is treated as a separate fund. Morningstar uses each fund's most current, publicly available prospectus at the time the average is calculated.

The performance data shown represents past performance, which does not guarantee future results. Investment return and principal value of an investment will fluctuate; therefore, you may have a gain or loss when you sell your shares. Current performance may be higher or lower than the performance stated. To learn more or to obtain the most recent month-end performance, call Fidelity at 1-800-343-3548.

Total returns are historical and include change in share value and reinvestment of dividends and capital gains, if any. Cumulative total returns are reported as of the period indicated. Life of Fund figures are reported as of the inception date to the period indicated. These figures do not include the effect of sales charges, if any, as these charges are waived for contributions made through your company's employee benefit plans. If sales charges were included, returns would have been lower.

Indices are unmanaged and you cannot invest directly in an index.

The gross expense ratio is the total annual fund or class operating expenses (before waivers or reimbursements) paid by the fund and stated as a percent of the fund's total net assets. For mutual funds, the values were drawn from their respective prospectuses.

An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. Although money market funds seek to preserve the value of your investment at $1 per share, it is possible to lose money by investing in these funds.
