Rowe Price Corporate Income Fund SUMMARY Fees and Expenses of the Fund <center>Shareholder fees (fees paid directly from your investment)</center> 0 <center>Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)</center> The fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the funds performance. During the most recent fiscal year, the funds portfolio turnover rate was 72.5% of the average value of its portfolio. 0.0525 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. <div style="display:none">~ http://www.troweprice.com/role/ScheduleAnnualFundOperatingExpensesTRowePriceCorporateIncomeFundInc column period compact * ~</div> This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the funds operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 66 208 Investments, Risks, and Performance Principal Investment Strategies 0.0423 0.0768 Average Annual Total Returns<center> Periods ended December 31, 2011</center> 1-800-225-5132 485BPOS T.

Holdings will mainly consist of investment-grade bonds, although the fund has the flexibility to purchase some noninvestment-grade bonds (also called high-yield or junk bonds). The fund may invest in other securities in an effort to enhance income and achieve capital growth. These include: convertible securities, preferred stock, and equities, together limited to no more than 10% of total assets; mortgage- and asset-backed securities, including some mortgage derivatives, together limited to no more than 5% of total assets; and U.S. Treasury and agency securities. In addition, up to 10% of the funds total assets may be invested in non-U.S. dollar-denominated fixed income securities, and there is no limit on the funds investments in U.S. dollar-denominated foreign securities. The fund does not have any maturity restrictions on the securities it purchases, but normally the portfolios weighted average maturity is expected to be between four and 15 years. At least 85% of the funds net assets must have received an investment-grade rating (AAA, AA, A, or BBB, or an equivalent rating) from at least one major credit rating agency or, if not rated by any credit rating agency, deemed to be of investment-grade quality by T. Rowe Price. Such investment-grade investments could include split-rated securities, which are securities that are rated as investment-grade by at least one credit rating agency but rated below investment grade by another agency. Up to 15% of the funds net assets can be invested in noninvestment-grade securities. The fund will not purchase any individual bond that is rated below B (or equivalent) by any major credit rating agency, and the funds investments in B rated bonds will not exceed 5% of its net assets. The funds investment program provides some flexibility in seeking high income. Within the limits described, the fund can seek the most advantageous combination of securities. For example, when the difference is small between the yields of various quality levels, or the outlook warrants, the fund may concentrate investments in higher-quality issues. When the difference is large, the fund may move down the credit scale in search of higher yields. Likewise, the fund may purchase bonds issued by foreign companies, including U.S. dollar-denominated Yankee bonds, when they offer higher yields than U.S. bonds of comparable quality and maturity. The fund may sell holdings for a variety of reasons, such as to adjust the portfolios average maturity, duration, or credit quality or to shift assets into and out of higher-yielding or lower-yielding securities or different sectors. As with any mutual fund, there is no guarantee that the fund will achieve its objective. The funds share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund are summarized as follows: Active management risk The fund is subject to the risk that the investment advisers judgments about the attractiveness, value, or potential appreciation of the funds investments may prove to be incorrect. If the securities selected and strategies employed by the fund fail to produce the intended results, the fund could underperform other funds with similar objectives and investment strategies. Interest rate risk This is the risk that a rise in interest rates will cause the price of a fixed rate debt security to fall. Generally, securities with longer maturities and funds with longer weighted average maturities carry greater interest rate risk. Credit risk This is the risk that an issuer of a debt security could suffer an adverse change in financial condition that results in a payment default, security downgrade, or inability to meet a financial obligation. Liquidity risk This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price. Foreign investing risk This is the risk that the funds investments in foreign securities may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar. Prepayment risk and extension risk Prepayment risk is the risk that the principal on any debt security with an embedded call option may be prepaid at any time, which could reduce yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Extension risk may result from a rise in interest rates, which tends to make callable debt securities more volatile. 0.0252 -0.0999 <center>Corporate Income Fund Calendar Year Returns</center> 0.0559 0.0549 0.0621 0.0418 0.0413 2009-06-30 0.1028 Worst Quarter 2008-09-30 false 2012-05-31 <div style="display:none">~ http://www.troweprice.com/role/ScheduleAverageAnnualTotalReturnsTransposedTRowePriceCorporateIncomeFundInc column period compact * ~</div> 0.0815 0.0636 0.0719 0.062 After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.
