Fund Profile

What is the fund`s objective?

The fund seeks the highest level of income consistent with the preservation of capital over time by investing primarily in marketable debt securities.

What is the fund`s principal investment strategy?

In seeking income and capital preservation, the fund pursues a total return strategy. Active management of the portfolio can result in bonds being sold at gains or losses. However, over the long term, the fund seeks to achieve its objective by investing primarily in income-producing securities that possess what we believe are favorable total return (income plus changes in principal) characteristics.

The fund will invest at least 80% of the fund`s total assets in income-producing securities, which may include U.S. government and agency obligations, mortgage- and asset-backed securities, corporate bonds, foreign securities, collateralized mortgage obligations (CMOs), and others, including, on occasion, equities.

<R>
Eighty percent of the debt securities purchased by the fund will be rated investment grade (AAA, AA, A, BBB, or equivalent) by each of the major credit rating agencies (Standard & Poor`s, Moody`s, and Fitch IBCA, Inc.) that have assigned a rating to the security. If the security is unrated, it must be deemed to be of investment-grade quality by T. Rowe Price. Up to 15% of total assets may be invested in "split-rated securities," or those rated investment grade by at least one rating agency but below investment grade by others. In addition, the fund may invest up to 5% of total assets in securities that have not received an investment grade rating by any major credit rating agency.
</R>

<R>
Investment restrictions, such as a required minimum or maximum investment in a particular type of security, are measured at the time the fund purchases a security. The status, market value, maturity, credit quality, or other characteristics of the fund`s securities may change after they are purchased, and this may cause the amount of the fund`s assets invested in such securities to exceed the stated maximum restriction or fall below the stated minimum restriction. If this occurs, it would not be considered a violation of the investment restriction.
</R>

<R>
The fund has considerable flexibility in seeking high yields. There are no maturity restrictions, so we can purchase longer-term bonds, which tend to have higher yields than shorter-term issues. However, the portfolio`s weighted average maturity is expected to be between four and 15 years. In addition, when there is a large yield difference between the various quality levels, we may move down the credit scale and purchase lower-rated bonds with higher yields. When the difference is small or the outlook warrants, we may concentrate investments in higher-rated issues.

Fund Profile

The fund may also invest in other securities, including futures, options, and swaps, in keeping with its objective.

The fund may sell holdings for a variety of reasons, such as to adjust the portfolio`s average maturity or quality or to shift assets into higher-yielding securities or different sectors.

Further information about the fund`s investments, including a review of market conditions and fund strategies and their impact on performance, is available in the annual and semiannual shareholder reports.

What are the main risks of investing in the fund?

  • Interest rate risk  This is the risk that an increase in interest rates will likely cause the fund`s share price to fall, resulting in a loss of principal. That`s because the bonds and notes in the fund`s portfolio become less attractive to other investors when securities with higher yields become available. Even GNMAs and other securities (whose principal and interest payments are guaranteed) can decline in price if rates rise. Generally speaking, the longer a bond`s maturity, the greater its potential for price declines if rates rise and for price gains if rates fall. Because the fund may invest in bonds of any maturity, it carries more interest rate risk than short-term bond funds. If the fund purchases longer-maturity bonds and interest rates rise unexpectedly, the fund`s price could decline.
  • Credit risk  This risk is the chance that any of the fund`s holdings will have their credit ratings downgraded or will default (fail to make scheduled interest or principal payments), potentially reducing the fund`s income level and share price.
  • Most investment-grade (AAA through BBB) securities have relatively low financial risk and a relatively high probability of future payment. However, securities rated BBB are more susceptible to adverse economic conditions and may have speculative characteristics. Securities rated below investment grade (junk or high-yield bonds) should be regarded as speculative because their issuers are more susceptible to financial setbacks and recession than more creditworthy companies. If the fund invests in securities whose issuers develop unexpected credit problems, the fund`s price could decline.

    The fund may continue to hold a security that has been downgraded or loses its investment-grade rating after purchase.

    <R>
  • Foreign investing risk  To the extent the fund holds foreign bonds, it will be subject to special risks, whether the bonds are denominated in U.S. dollars or foreign currencies. These risks include potentially adverse political and economic developments overseas, greater volatility, lower liquidity, and the possibility that

  • foreign currencies will decline against the dollar, lowering the value of securities denominated in those currencies and possibly the fund`s share price.
  • </R>

  • Prepayment risk and extension risk  A mortgage-backed bond, unlike most other bonds, can be hurt when interest rates fall because homeowners tend to refinance and prepay principal. Receiving increasing prepayments in a falling interest rate environment causes the average maturity of the portfolio to shorten, reducing its potential for price gains. It also requires the fund to reinvest proceeds at lower interest rates, which reduces the portfolio`s total return and yield, and may even cause certain bond prices to fall below the level the fund paid for them, resulting in a capital loss. Any of these developments could result in a decrease in the fund`s income, share price, or total return.
  • Extension risk refers to a rise in interest rates that causes a fund`s average maturity to lengthen unexpectedly due to a drop in mortgage prepayments. This would increase the fund`s sensitivity to rising rates and its potential for price declines.

  • Derivatives risk  To the extent the fund uses futures, swaps, and other derivatives, it is exposed to additional volatility and potential losses.
  • As with any mutual fund, there can be no guarantee the fund will achieve its objective.

    The share price and income level of the fund will fluctuate with changing market conditions and interest rate levels. When you sell your shares, you may lose money. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

    How can I tell if the fund is appropriate for me?

    Consider your investment goals, your time horizon for achieving them, and your tolerance for risk. The fund may be appropriate for you if you seek an attractive level of income and are willing to accept the risk of a declining share price when interest rates rise. Steadily reinvesting the fund`s income is a conservative strategy for building capital over time. If you are investing primarily for safety and liquidity, you should consider a money market fund.

    The fund can be used in both regular and tax-deferred accounts, such as IRAs.

    The fund should not represent your complete investment program or be used for short-term trading purposes.

    How has the fund performed in the past?

    The bar chart showing calendar year returns and the average annual total returns table indicate risk by illustrating how much returns can differ from one year to the next and how fund performance compares with that of a comparable market index. Fund past returns (before and after taxes) are not necessarily an indication of future performance.

    The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

    In addition, the average annual total returns table shows hypothetical after-tax returns to suggest how taxes paid by the shareholder may influence returns. Actual after-tax returns depend on each investor`s situation and may differ from those shown. After-tax returns are not relevant if the shares are held in a tax-deferred account, such as a 401(k) or IRA. During periods of fund losses, the post-liquidation after-tax return may exceed the fund`s other returns because the loss generates a tax benefit that is factored into the result.

    Returns are based on changes in principal value, reinvested dividends, and capital gain distributions, if any. Returns before taxes do not reflect effects of any income or capital gains taxes. Taxes are computed using the highest federal income tax rate. The after-tax returns reflect the rates applicable to ordinary and qualified dividends and capital gains effective in 2003. The returns do not reflect the impact of state and local taxes. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of fund shares assume the shares were sold at period-end and, therefore, are also adjusted for any capital gains or losses incurred by the shareholder. Market indexes do not include expenses, which are deducted from fund returns, or taxes.
