The following information replaces the similar information found in the "Investment Policies and Limitations" section on page 13.

Loans and Other Direct Debt Instruments. Direct debt instruments are interests in amounts owed by a corporate, governmental, or other borrower to lenders or lending syndicates (loans and loan participations), to suppliers of goods or services (trade claims or other receivables), or to other parties. Direct debt instruments involve a risk of loss in case of default or insolvency of the borrower and may offer less legal protection to the purchaser in the event of fraud or misrepresentation, or there may be a requirement that a fund supply additional cash to a borrower on demand. A fund may acquire loans by buying an assignment of all or a portion of the loan from a lender or by purchasing a loan participation from a lender or other purchaser of a participation. Fidelity Advisor Intermediate Bond Fund, Fidelity Investment Grade Bond Fund, and Fidelity Total Bond Fund also may acquire loans directly at the time of the loan's closing.

Lenders and purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the borrower for payment of interest and repayment of principal. If scheduled interest or principal payments are not made, the value of the instrument may be adversely affected. Loans that are fully secured provide more protections than an unsecured loan in the event of failure to make scheduled interest or principal payments. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the borrower's obligation, or that the collateral could be liquidated. Indebtedness of borrowers whose creditworthiness is poor involves substantially greater risks and may be highly speculative. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or may pay only a small fraction of the amount owed. Direct indebtedness of developing countries also involves a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

Direct lending and investments in loans through direct assignment of a financial institution's interests with respect to a loan may involve additional risks. For example, if a loan is foreclosed, the lender/purchaser could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is conceivable that under emerging legal theories of lender liability, a purchaser could be held liable as a co-lender. Direct debt instruments may also involve a risk of insolvency of the lending bank or other intermediary.

A loan is often administered by a bank or other financial institution that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. Unless, under the terms of the loan or other indebtedness, the purchaser has direct recourse against the borrower, the purchaser may have to rely on the agent to apply appropriate credit remedies against a borrower. If assets held by the agent for the benefit of a purchaser were determined to be subject to the claims of the agent's general creditors, the purchaser might incur certain costs and delays in realizing payment on the loan or loan participation and could suffer a loss of principal or interest.

Direct indebtedness may include letters of credit, revolving credit facilities, or other standby financing commitments that obligate lenders/purchasers to make additional cash payments on demand. These commitments may have the effect of requiring a lender/purchaser to increase its investment in a borrower at a time when it would not otherwise have done so, even if the borrower's condition makes it unlikely that the amount will ever be repaid.

Each fund limits the amount of total assets that it will invest in any one issuer or in issuers within the same industry (see the fund's investment limitations). For purposes of these limitations, a fund generally will treat the borrower as the "issuer" of indebtedness held by the fund. In the case of loan participations where a bank or other lending institution serves as financial intermediary between a fund and the borrower, if the participation does not shift to the fund the direct debtor-creditor relationship with the borrower, SEC interpretations require a fund, in appropriate circumstances, to treat both the lending bank or other lending institution and the borrower as "issuers" for these purposes. Treating a financial intermediary as an issuer of indebtedness may restrict a fund's ability to invest in indebtedness related to a single financial intermediary, or a group of intermediaries engaged in the same industry, even if the underlying borrowers represent many different companies and industries.

Jeffrey Moore serves as co-manager of Fidelity Total Bond Fund. The following information supplements similar information found in the "Management Contracts" section beginning on page 40.

Jeffrey Moore is co-manager of Fidelity Total Bond Fund and receives compensation for his services. As of June 30, 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 Total Bond Fund is based on the pre-tax investment performance of the fund measured against the Barclays^® U.S. Universal Bond Index. 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.
