The following information replaces the similar information found in the "Managment Contract" section on page 33.

Chris Sharpe and Derek Young are the lead co-managers of Fidelity Four-in-One Index Fund and do not receive compensation for their services to this fund. They receive compensation for managing other funds and accounts at FMR or its affiliates as described below. As of July 31, 2005, portfolio manager compensation generally consists of a fixed base salary determined periodically (typically annually), a bonus, and, in certain cases, participation in several types of equity-based compensation plans. A portion of a portfolio manager's compensation may be deferred based on criteria established by FMR or at the election of the portfolio manager.

A portfolio manager's base salary is determined by level of responsibility and tenure at FMR or its affiliates. A portfolio manager's bonus is based on several components calculated separately over his or her tenure over multiple measurement periods that eventually encompass periods of up to five years. The primary components of a portfolio manager's bonus are based on (i) the pre-tax investment performance of a portfolio manager's fund(s) and account(s) relative to a defined peer group and relative to a benchmark index assigned to each fund or account, and (ii) the investment performance of a broad range of other FMR equity funds and accounts. A subjective component of each portfolio manager's bonus is based on the portfolio manager's overall contribution to management of FMR. A portfolio manager also is compensated under equity-based compensation plans linked to increases or decreases in the net asset value of the stock of FMR Corp., FMR's parent company. FMR Corp. is a diverse financial services company engaged in various activities that include fund management, brokerage, retirement and employer administrative services.

A portfolio manager's compensation plan may give rise to potential conflicts of interest. A portfolio manager's base pay tends to increase with additional and more complex responsibilities that may include, but are not limited to, increased assets under management and a portion of the bonus relates to marketing efforts, which together indirectly link compensation to sales. When a portfolio manager takes over a fund or an account, the time period over which performance is measured may be adjusted to provide a transition period in which to assess the portfolio. The management of multiple funds and accounts (including proprietary accounts) may give rise to potential conflicts of interest if the funds and accounts have different objectives, benchmarks, time horizons, and fees as a portfolio manager must allocate his or her time and investment ideas across multiple funds and accounts. In addition, a fund's trade allocation policies and procedures may give rise to conflicts of interest if the fund's orders do not get fully executed due to being aggregated with those of other accounts managed by FMR. A portfolio manager may execute transactions for another fund or account that may adversely impact the value of securities held by a fund. Securities selected for funds or accounts other than a fund may outperform the securities selected for the fund. Personal accounts may give rise to potential conflicts of interest; trading in personal accounts is restricted by the fund's Code of Ethics.
