Supplement to the

Fidelity® Inflation-Protected Bond Fund (FINPX)

A Class of shares of Fidelity Inflation-Protected Bond Fund

A Fund of Fidelity Fixed-Income Trust

STATEMENT OF ADDITIONAL INFORMATION

May 28, 2011

Effective October 14, 2011, Fidelity Fixed-Income Trust was renamed Fidelity Salem Street Trust.

Franco Castagliuolo serves as co-manager of the fund. The following information supplements similar information found in the "Management Contract" section beginning on page 28.

Franco Castagliuolo is co-manager of Fidelity® Inflation-Protected Bond Fund and receives compensation for his services. As of March 31, 2012, portfolio manager compensation generally consists of a fixed base salary determined periodically (typically annually), a bonus, in certain cases, participation in several types of equity-based compensation plans, and, if applicable, relocation plan benefits. A portion of the portfolio manager's compensation may be deferred based on criteria established by FMR or at the election of the portfolio manager.

The portfolio manager's base salary is determined by level of responsibility and tenure at FMR or its affiliates. The primary components of the portfolio manager's bonus are based on (i) the pre-tax investment performance of the portfolio manager's fund(s) and account(s) measured against a benchmark index assigned to each fund or account, and (ii) the investment performance of other FMR taxable bond funds and accounts. The pre-tax investment performance of the portfolio manager's fund(s) and account(s) is weighted according to his tenure on those fund(s) and account(s) and the average asset size of those fund(s) and account(s) over his tenure. Each component is calculated separately over the portfolio manager's tenure on those fund(s) and account(s) over a measurement period that initially is contemporaneous with his tenure, but that eventually encompasses rolling periods of up to three years for the comparison to a benchmark index. A smaller, subjective component of the portfolio manager's bonus is based on the portfolio manager's overall contribution to management of FMR. The portion of the portfolio manager's bonus that is linked to the investment performance of Fidelity Inflation-Protected Bond Fund is based on the pre-tax investment performance of the fund measured against the Barclays® U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L). The 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 LLC, FMR's parent company. FMR LLC is a diverse financial services company engaged in various activities that include fund management, brokerage, retirement and employer administrative services. If requested to relocate their primary residence, portfolio managers also may be eligible to receive benefits, such as home sale assistance and payment of certain moving expenses, under relocation plans for most full-time employees of FMR LLC and its affiliates.

The portfolio manager's compensation plan may give rise to potential conflicts of interest. Although investors in the fund may invest through either tax-deferred accounts or taxable accounts, the portfolio manager's compensation is linked to the pre-tax performance of the fund, rather than its after-tax performance. The portfolio manager's base pay tends to increase with additional and more complex responsibilities that include 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 the portfolio manager must allocate his 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 or an affiliate. The 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 other funds or accounts may outperform the securities selected for the fund. Portfolio managers may be permitted to invest in the funds they manage, even if a fund is closed to new investors. Trading in personal accounts, which may give rise to potential conflicts of interest, is restricted by a fund's Code of Ethics.

A smaller, subjective component of the portfolio manager's bonus is based on the portfolio manager's overall contribution to management of FMR. The portion of the portfolio manager's bonus that is linked to the investment performance of Fidelity Strategic Real Return Fund is based on the pre-tax investment performance of the portion of the fund's assets he manages measured against the Barclays® U.S. TIPS Index (Series-L).

STATEMENT OF ADDITIONAL INFORMATION

November 29, 2011

Franco Castagliuolo serves as co-manager of Fidelity Strategic Real Return Fund. Mr. Castagliuolo will receive compensation for his services.

The following information supplements information found in the "Management Contract"section beginning on page 38.

Franco Castagliuolo is co-manager of Fidelity Strategic Real Return Fund and receives compensation for his services. As of March 31, 2012, portfolio manager compensation generally consists of a fixed base salary determined periodically (typically annually), a bonus, in certain cases, participation in several types of equity-based compensation plans, and, if applicable, relocation plan benefits. A portion of the portfolio manager's compensation may be deferred based on criteria established by FMR or at the election of the portfolio manager.

The portfolio manager's base salary is determined by level of responsibility and tenure at FMR or its affiliates. The primary components of the portfolio manager's bonus are based on (i) the pre-tax investment performance of the portfolio manager's fund(s) and account(s) measured against a benchmark index assigned to each fund or account, and (ii) the investment performance of other FMR taxable bond funds and accounts. The pre-tax investment performance of the portfolio manager's fund(s) and account(s) is weighted according to his tenure on those fund(s) and account(s) and the average asset size of those fund(s) and account(s) over his tenure. Each component is calculated separately over the portfolio manager's tenure on those fund(s) and account(s) over a measurement period that initially is contemporaneous with his tenure, but that eventually encompasses rolling periods of up to three years for the comparison to a benchmark index. A smaller, subjective component of the portfolio manager's bonus is based on the portfolio manager's overall contribution to management of FMR. The portion of the portfolio manager's bonus that is linked to the investment performance of Fidelity Strategic Real Return Fund is based on the pre-tax investment performance of the portion of the fund's assets he manages measured against the Barclays® U.S. TIPS Index (Series-L). The 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 LLC, FMR's parent company. FMR LLC is a diverse financial services company engaged in various activities that include fund management, brokerage, retirement and employer administrative services. If requested to relocate their primary residence, portfolio managers also may be eligible to receive benefits, such as home sale assistance and payment of certain moving expenses, under relocation plans for most full-time employees of FMR LLC and its affiliates.

The portfolio manager's compensation plan may give rise to potential conflicts of interest. Although investors in the fund may invest through either tax-deferred accounts or taxable accounts, the portfolio manager's compensation is linked to the pre-tax performance of the fund, rather than its after-tax performance. The portfolio manager's base pay tends to increase with additional and more complex responsibilities that include 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 the portfolio manager must allocate his 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 or an affiliate. The 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 other funds or accounts may outperform the securities selected for the fund. Portfolio managers may be permitted to invest in the funds they manage, even if a fund is closed to new investors. Trading in personal accounts, which may give rise to potential conflicts of interest, is restricted by a fund's Code of Ethics.
