Fidelity^® Four-in-One Index Fund

Prospectus

The following information replaces similar information found under the "Buying and Selling Shares" heading in the "Shareholder Information" section beginning on page 14.

The fund may reject for any reason, or cancel as permitted or required by law, any purchase or exchange, including transactions deemed to represent excessive trading, at any time.

Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to a fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares in cases in which fluctuations in markets are not fully priced into the fund's NAV.

The Board of Trustees has adopted policies designed to discourage excessive trading of fund shares. Excessive trading activity in the fund is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder sells fund shares (including exchanges) within 30 days of the purchase date.

Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for at least 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block. Repeat offenders may be subject to long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's control at any time. In addition to enforcing these roundtrip limitations, the fund may in its discretion restrict, reject or cancel purchases or exchanges that, in FMR's opinion, may be disruptive to the management of the fund or otherwise not be in the fund's interests.

The following transactions are exempt from the fund's excessive trading policy described above: (i) transactions of $1,000 or less, (ii) systematic withdrawal and/or contribution programs, (iii) mandatory retirement distributions, and (iv) transactions initiated by a retirement plan sponsor or sponsors of certain employee benefit plans or other related accounts. In addition, the fund's excessive trading policy does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-fund(s) or other strategy funds. A qualified fund-of-fund(s) is a mutual fund, qualified tuition program, or other strategy fund consisting of qualified plan assets that either applies the Fidelity funds' excessive trading policies to shareholders at the fund-of-fund(s) level, or demonstrates that the fund-of-fund(s) has an investment strategy coupled with policies designed to control frequent trading that are reasonably likely to be effective as determined by the Fidelity funds' Treasurer.

Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple investors, are a common form of holding shares among retirement plans and financial intermediaries such as brokers, advisers and third-party administrators. Individual trades in omnibus accounts are often not disclosed to the fund, making it difficult to determine whether a particular shareholder is engaging in excessive trading. Excessive trading in omnibus accounts is likely to go undetected by the fund and may increase costs to the fund and disrupt its portfolio management.

Under policies adopted by the Board of Trustees, intermediaries will be permitted to apply the fund's excessive trading policy (described above), or their own excessive trading policy if approved by Fidelity. In these cases, the fund will typically not request or receive individual account data but will rely on the intermediary to monitor trading activity in good faith in accordance with its or the fund's policies. Reliance on intermediaries increases the risk that excessive trading may go undetected. For other intermediaries, the fund will generally monitor trading activity at the omnibus account level to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. The fund may request transaction information, as frequently as daily, from any intermediary at any time, and may apply the fund's policy to such transactions exceeding $5,000. The fund may prohibit purchases of fund shares by an intermediary or by some or all of any intermediary's clients. Fidelity will apply these policies through a phased implementation. There is no assurance that Fidelity will request data with sufficient frequency to detect or deter excessive trading in omnibus accounts effectively.

If you purchase or sell fund shares through a financial intermediary, you may wish to contact the intermediary to determine the policies applicable to your account.

For employer-sponsored retirement plans, only participant directed exchanges count toward the roundtrip limits. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund.

The fund will monitor aggregate trading activity of adviser transactions to attempt to identify excessive trading in qualified wrap programs, as defined below. Excessive trading by an adviser will lead to fund blocks and the wrap program will lose its qualified status. Adviser transactions will not be matched with client-directed transactions unless the wrap program ceases to be a qualified wrap program (but all client-directed transactions will be subject to the fund's excessive trading policies). A qualified wrap program is: (i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, (ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and (iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.

The fund reserves the right at any time to restrict purchases or exchanges or impose conditions that are more restrictive on excessive or disruptive trading than those stated in this prospectus. The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency. The fund reserves the right to modify its policies at any time without prior notice to shareholders.

The fund does not knowingly accommodate frequent purchases and redemptions of fund shares by investors, except to the extent permitted by the policies described above.

As described above in "Valuing Shares," the fund also uses fair value pricing to help reduce arbitrage opportunities available to short-term traders.

There is no assurance that the fund's excessive trading policies will be effective, or will successfully detect or deter excessive or disruptive trading.
