Normally, the fund will also maintain a &#8220;plus&#8221; portion of its portfolio in other sectors of the bond market, including high yield, non-U.S. dollar-denominated, and emerging market securities, to seek additional value.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "> Under normal conditions, the fund expects to maintain an effective duration within +/-20% of the Barclays U.S. Aggregate Bond Index. As of July 31, 2012, the effective duration of this index was 4.9 years; however, it will change over time. The fund, in the aggregate, will seek to maintain a weighted average credit rating of A- or better, based on the weighted average credit quality of the fund&#8217;s portfolio securities. </font> <br /><br /><font style="font-family: serif; font-size: 10pt; "> Individual bond investments in the core portfolio will be investment grade, with a minimum credit quality of BBB- (or an equivalent rating). Ratings will be determined, at the time of purchase, by at least one major credit rating agency or, if not so rated, a comparable rating by T. Rowe Price. If a security is split-rated (i.e., one rating below investment grade and one at or above investment grade), the higher rating will be used. </font> <br /><br /><font style="font-family: serif; font-size: 10pt; "> The plus portion of the fund&#8217;s portfolio may consist of below investment-grade &#8220;junk&#8221; bonds issued by U.S. and other developed country companies (not to exceed 20% of net assets), below investment-grade emerging market debt securities (not to exceed 10% of net assets), non-U.S. dollar-denominated securities (not to exceed 20% of net assets), and convertible and preferred securities (not to exceed 10% of net assets), as well as other investments. The fund may hold non-U.S. currencies without holding any bonds or other securities denominated in those currencies. </font> <br /><br /><font style="font-family: serif; font-size: 10pt; "> The fund may continue to hold an investment in its core portfolio that is downgraded to below investment grade after purchase. If such rating downgrades cause high yield exposure to exceed 20% of net assets or below investment-grade emerging market securities to exceed 10% of net assets, the fund will reduce exposure within a reasonable period of time.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; ">While most assets will typically be invested in bonds, the fund also uses interest rate futures and forward currency exchange contracts in keeping with the fund&#8217;s objectives. Interest rate futures would typically be used to manage the fund&#8217;s exposure to interest rate changes or to adjust portfolio duration. Forward currency exchange contracts would be used to gain exposure to certain currencies expected to increase or decrease in value relative to other currencies or to protect the fund&#8217;s foreign bond holdings from adverse currency movements relative to the U.S. dollar.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "> The fund may sell holdings for a variety of reasons, such as to adjust the portfolio&#8217;s average maturity, duration, or credit quality or to shift assets into and out of higher-yielding or lower-yielding securities or different sectors.</font> <font style="font-family: serif; font-size: 10pt; "> As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund&#8217;s 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:</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Active management risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> The fund is subject to the risk that the investment adviser&#8217;s judgments about the attractiveness, value, or potential appreciation of the fund&#8217;s 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.</font> <br /><br /> <font style="font-family: serif; font-size: 10pt; "><b><i>Interest rate risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> 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.</font> <br /><br /> <font style="font-family: serif; font-size: 10pt; "><b><i>Credit risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> 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. The fund&#8217;s exposure to credit risk is increased to the extent the fund invests in noninvestment-grade &#8220;junk&#8221; bonds. Junk bonds should be considered speculative as they carry greater risk of default and erratic price swings due to adverse changes in the credit quality of the issuer.</font> <br /><br /> <font style="font-family: serif; font-size: 10pt; "><b><i>Liquidity risk</i></b> </font><font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.</font><br /><br /> <font style="font-family: serif; font-size: 10pt; "><b><i>Foreign investing risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> This is the risk that the fund&#8217;s 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. These risks are heightened for the fund&#8217;s investments in emerging markets. Any attempts at hedging currencies may not be successful and could cause the fund to lose money. </font><br /><br /> <font style="font-family: serif; font-size: 10pt; "><b><i>Prepayment risk and extension risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> Prepayment risk is the risk that the principal on mortgage-backed securities, other asset-backed securities or 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.

Normally, the fund will also maintain a &#8220;plus&#8221; portion of its portfolio in other sectors of the bond market, including high yield, non-U.S. dollar-denominated, and emerging market securities, to seek additional value.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">Under normal conditions, the fund expects to maintain an effective duration within +/-20% of the Barclays U.S. Aggregate Bond Index. As of July 31, 2012, the effective duration of this index was 4.9 years; however, it will change over time. The fund, in the aggregate, will seek to maintain a weighted average credit rating of A- or better, based on the weighted average credit quality of the fund&#8217;s portfolio securities.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">Individual bond investments in the core portfolio will be investment grade, with a minimum credit quality of BBB- (or an equivalent rating). Ratings will be determined, at the time of purchase, by at least one major credit rating agency or, if not so rated, a comparable rating by T. Rowe Price. If a security is split-rated (i.e., one rating below investment grade and one at or above investment grade), the higher rating will be used.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">The plus portion of the fund&#8217;s portfolio may consist of below investment-grade &#8220;junk&#8221; bonds issued by U.S. and other developed country companies (not to exceed 20% of net assets), below investment-grade emerging market debt securities (not to exceed 10% of net assets), non-U.S. dollar-denominated securities (not to exceed 20% of net assets), and convertible and preferred securities (not to exceed 10% of net assets), as well as other investments. The fund may hold non-U.S. currencies without holding any bonds or other securities denominated in those currencies.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">The fund may continue to hold an investment in its core portfolio that is downgraded to below investment grade after purchase.

Interest rate futures would typically be used to manage the fund&#8217;s exposure to interest rate changes or to adjust portfolio duration. Forward currency exchange contracts would be used to gain exposure to certain currencies expected to increase or decrease in value relative to other currencies or to protect the fund&#8217;s foreign bond holdings from adverse currency movements relative to the U.S. dollar.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">The fund may sell holdings for a variety of reasons, such as to adjust the portfolio&#8217;s average maturity, duration, or credit quality or to shift assets into and out of higher-yielding or lower-yielding securities or different sectors.</font> <font style="font-family: serif; font-size: 10pt; ">As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund&#8217;s 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:</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Active management risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> The fund is subject to the risk that the investment adviser&#8217;s judgments about the attractiveness, value, or potential appreciation of the fund&#8217;s 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.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Interest rate risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">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.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Credit risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> 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. The fund&#8217;s exposure to credit risk is increased to the extent the fund invests in noninvestment-grade &#8220;junk&#8221; bonds. Junk bonds should be considered speculative as they carry greater risk of default and erratic price swings due to adverse changes in the credit quality of the issuer.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Liquidity risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Foreign investing risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> This is the risk that the fund&#8217;s 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. These risks are heightened for the fund&#8217;s investments in emerging markets. Any attempts at hedging currencies may not be successful and could cause the fund to lose money.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Prepayment risk and extension risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">Prepayment risk is the risk that the principal on mortgage-backed securities, other asset-backed securities or 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 mortgage-backed securities, asset-backed securities, and other callable debt securities more volatile.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i> Derivatives risk</i></b></font><font style="font-family: serif; font-size: 10pt; "> To the extent the fund uses interest rate futures and forward currency exchange contracts, it is exposed to additional volatility in comparison to investing directly in bonds and other debt securities.

Most, if not all, of the loans in which the fund invests are rated below investment-grade (BB and lower, or an equivalent rating) or are not rated by a major credit rating agency. The loans in which the fund invests are often referred to as &#8220;leveraged loans&#8221; because the borrowing companies have significantly more debt than equity.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">The loans held by the fund may be senior or subordinate obligations of the borrower, although the fund normally invests the majority of its assets in senior floating rate loans. In the event of bankruptcy, holders of senior floating rate loans are typically paid (to the extent assets are available) before certain other creditors of the borrower (e.g., bondholders and stockholders). Holders of subordinate loans may be paid after more senior bondholders. Loans may or may not be secured by collateral.

The interest rates on floating rate loans are generally based on a percentage above LIBOR (the London Interbank Offered Rate), a U.S. bank&#8217;s prime or base rate, the overnight federal funds rate, or another rate. Floating rate loans may be structured and administered by a financial institution that acts as the agent of the lenders participating in the floating rate loan. The fund may acquire floating rate loans directly from a lender or through the agent, as an assignment from another lender who holds a floating rate loan, or as a participation interest in another lender&#8217;s floating rate loan or portion thereof.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">In buying and selling loans, the fund relies on its fundamental analysis of each company and the company&#8217;s ability to pay principal and interest in light of its current financial condition, its industry position, and economic and market conditions. The fund may purchase other floating rate debt instruments with credit and interest rate characteristics similar to the floating rate loans that it purchases.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">In addition to the fund&#8217;s investments in loans, the fund may invest in a variety of debt securities, such as government and agency debt obligations, and investment-grade and high yield corporate bonds. High yield bonds, also known as &#8220;junk&#8221; bonds, are rated below investment grade and should be considered speculative. They generally provide high income in an effort to compensate investors for their higher risk of default, which is the failure to make required interest or principal payments. High yield bond issuers include small or relatively new companies lacking the history or capital to merit investment-grade status, former blue chip companies downgraded because of financial problems, companies electing to borrow heavily to finance or avoid a takeover or buyout, and firms with heavy debt loads.

The fund&#8217;s share price fluctuates, which means you could lose money by investing in the fund. The fund is exposed to interest rate risk like more traditional bond funds, but credit and liquidity risks tend to be more important. The principal risks of investing in this fund are summarized as follows:</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Active management risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">The fund is subject to the risk that the investment adviser&#8217;s judgments about the attractiveness, value, or potential appreciation of the fund&#8217;s investments may prove to be incorrect.

The fund&#8217;s overall credit risk is increased to the extent it invests in loans not secured by collateral or if it purchases a participation interest in a loan.</font><br /><br /><font style="font-family: serif; font-size: 10pt; ">Because a significant portion of the fund&#8217;s investments may be rated below investment-grade (also known as &#8220;junk&#8221; securities), the fund is exposed to greater volatility than if it invested mainly in investment-grade bonds and loans. High yield bond and loan issuers are more likely to suffer an adverse change in financial condition that would result in the inability to meet a financial obligation. Accordingly, securities and loans involving such companies carry a higher risk of default and should be considered speculative.</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Impairment of collateral risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the value of collateral securing a floating rate loan could decline, be insufficient to satisfy the loan obligation, or be difficult to liquidate. The fund&#8217;s access to the collateral could be limited by bankruptcy or by the type of loan it purchases. As a result, a collateralized senior loan may not be fully collateralized and can decline significantly in value.</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Interest rate risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">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. Because interest payments on the fund&#8217;s floating rate investments are typically based on a spread over another interest rate, falling interest rates will result in less income for the fund, but will not typically result in the price volatility that a fixed rate holding could experience.</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Prepayment risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the principal on a loan or debt security will be prepaid prior to its maturity, reducing the potential for price gains. The rate of prepayments tends to increase as interest rates fall.</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Liquidity risk </i></b></font><font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price. Floating rate loans may not have an active trading market and often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price.</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Senior loans risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">Senior loans are subject to the risk that a court could subordinate a senior loan, which typically holds the most senior position in the issuer&#8217;s capital structure, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans.</font><br /><br /><font style="font-family: serif; font-size: 10pt; "><b><i>Foreign investing risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund&#8217;s 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.</font> <font style="font-family: serif; font-size: 10pt; ">The fund&#8217;s share price fluctuates, which means you could lose money by investing in the fund.</font> <font style="font-family: serif; font-size: 10pt; ">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.</font> <font style="font-family: serif; font-size: 10pt; ">After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or individual retirement account.</font> 0.0055 176 0.0168 0.0168 -0.0024 0.0122 0.0149 <div style="display:none">~ http://www.troweprice.com/role/ScheduleAverageAnnualTotalReturnsTransposedTRowePriceInstitutionalFloatingRateFund column period compact * ~</div> <font style="font-family: sans-serif; color: rgb(0, 79, 124); font-size: 9.5pt; "><b>Investment Objective</b></font> <font style="font-family: sans-serif; color: rgb(0, 79, 124); font-size: 9.5pt; "><b>Fees and Expenses </b></font> <font style="font-family: sans-serif; color: rgb(0, 79, 124); font-size: 9.5pt; "><b>Investment Objective</b></font> <font style="FONT-FAMILY: Sans-Serif; FONT-SIZE: 9.5pt; FONT-WEIGHT: bold">Portfolio Turnover</font> <font style="font-family: sans-serif; color: rgb(0, 79, 124); font-size: 9.5pt; "><b>Fees and Expenses</b></font> <font style="FONT-FAMILY: Sans-Serif; FONT-SIZE: 9.5pt;"><b>Portfolio Turnover</b></font> <font style="font-family: serif; font-size: 10pt; ">The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in a widely diversified portfolio of high yield corporate bonds, often called &#8220;junk&#8221; bonds, as well as income-producing convertible securities and preferred stocks that are rated below investment-grade or not rated by any major credit rating agency but deemed to be below investment-grade by T.

The principal risks of investing in this fund are summarized as follows:</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "><i><b>Active management risk</b></i> </font><font style="font-family: serif; font-size: 10pt; ">The fund is subject to the risk that the investment adviser&#8217;s judgments about the attractiveness, value, or potential appreciation of the fund&#8217;s 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.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "><i><b>Interest rate risk </b></i></font><font style="font-family: serif; font-size: 10pt; "> This is the risk that a rise in interest rates will cause the price of a fixed rate debt security to fall.

The fund is exposed to greater credit risk than other bond funds because companies issuing high yield bonds are usually not as strong financially and the securities they issue carry a higher risk of default.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "><i><b>Liquidity risk </b> </i></font><font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "><i><b>Foreign investing risk</b></i></font><font style="font-family: serif; font-size: 10pt; "> This is the risk that the fund&#8217;s 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.</font> <br /><br /><font style="font-family: serif; font-size: 10pt; "><i><b>Derivatives risk </b></i> </font><font style="font-family: serif; font-size: 10pt; ">To the extent the fund uses forward currency exchange contracts and credit default swaps, it is exposed to additional volatility in comparison to investing directly in bonds and other debt securities. These instruments can be illiquid and difficult to value, may involve leverage so that small changes produce disproportionate losses for the fund, and instruments not traded on an exchange are subject to the risk that a counterparty to the transaction will fail to meet its obligations under the derivatives contract. The fund&#8217;s principal use of derivatives involves the risk that anticipated changes in currency values, currency exchange rates, or the creditworthiness of an issuer will not be accurately predicted, which could significantly harm the fund&#8217;s performance.</font> <font style="font-family: serif; font-size: 10pt; ">Updated performance information is available through troweprice.com or may be obtained by calling 1-800-638-8790.</font> <font style="font-family: serif; font-size: 10pt; ">The fund&#8217;s share price fluctuates, which means you could lose money by investing in the fund.</font> <font style="font-family: serif; font-size: 10pt; ">The fund&#8217;s share price fluctuates, which means you could lose money by investing in the fund.</font> <font style="font-family: serif; font-size: 10pt; ">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. <font style="font-family: serif; font-size: 10pt; ">After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or individual retirement account.</font> <font style="font-family: serif; font-size: 10pt; ">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.</font> <font style="font-family: serif; font-size: 10pt; ">After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or individual retirement account.</font> <center><font style="font-family: sans-serif; color:#008000; font-size: 8.5pt; "><b>Institutional Floating Rate Fund &#8211; F Class</b></font><br/><font style="font-family: sans-serif; font-size: 6.5pt; font-weight: bold; "><i>Calendar Year Return</i></center></font> <font style="font-family: serif; font-size: 10pt; ">Updated performance information is available through troweprice.com or may be obtained by calling 1-800-638-8790.</font> 2009-06-30 0.1641 <font style="font-family: serif; font-size: 10pt; "><b>Worst Quarter</b></font> 2008-12-31 <div style="display:none">~ http://www.troweprice.com/role/ScheduleAverageAnnualTotalReturnsTransposedTRowePriceInstitutionalFloatingRateFundFClass column period compact * ~</div> 0.0365 -0.2119 0.0349 0.005 <font style="font-family: serif; font-size: 10pt; ">As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund&#8217;s share price fluctuates, which means you could lose money by investing in the fund. The fund is exposed to interest rate risk like more traditional bond funds, but credit and liquidity risks tend to be more important. The principal risks of investing in this fund are summarized as follows:</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Active management risk</i></b> </font><font style="font-family: serif; font-size: 10pt; ">The fund is subject to the risk that the investment adviser&#8217;s judgments about the attractiveness, value, or potential appreciation of the fund&#8217;s 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.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Credit risk</i></b> </font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that a loan borrower or issuer of a debt security could suffer an adverse change in financial condition that results in a payment default, inability to meet a financial obligation, or the downgrade of a fund holding. The fund&#8217;s overall credit risk is increased to the extent it invests in loans not secured by collateral or if it purchases a participation interest in a loan.</font><br/><br/><font style="font-family: serif; font-size: 10pt; ">Because a significant portion of the fund&#8217;s investments may be rated below investment-grade (also known as &#8220;junk&#8221; securities), the fund is exposed to greater volatility than if it invested mainly in investment-grade bonds and loans. High yield bond and loan issuers are more likely to suffer an adverse change in financial condition that would result in the inability to meet a financial obligation. Accordingly, securities and loans involving such companies carry a higher risk of default and should be considered speculative.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Impairment of collateral risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the value of collateral securing a floating rate loan could decline, be insufficient to satisfy the loan obligation, or be difficult to liquidate. The fund&#8217;s access to the collateral could be limited by bankruptcy or by the type of loan it purchases. As a result, a collateralized senior loan may not be fully collateralized and can decline significantly in value.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Interest rate risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">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. Because interest payments on the fund&#8217;s floating rate investments are typically based on a spread over another interest rate, falling interest rates will result in less income for the fund, but will not typically result in the price volatility that a fixed rate holding could experience.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Prepayment risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the principal on a loan or debt security will be prepaid prior to its maturity, reducing the potential for price gains. The rate of prepayments tends to increase as interest rates fall.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Liquidity risk</i></b> </font><font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund may not be able to sell a holding in a timely manner at a desired price. Floating rate loans may not have an active trading market and often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Senior loans risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">Senior loans are subject to the risk that a court could subordinate a senior loan, which typically holds the most senior position in the issuer&#8217;s capital structure, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans.</font><br/><br/><font style="font-family: serif; font-size: 10pt; "><b><i>Foreign investing risk</i></b></font> <font style="font-family: serif; font-size: 10pt; ">This is the risk that the fund&#8217;s 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.</font> 160 0.0349 0.0034 0.0263 0.0573 0.028 <center><font style="font-family: sans-serif; color:#008000; font-size: 8.5pt; "><b>Institutional High Yield Fund</b></font><br/> <font style="FONT-FAMILY: Sans-Serif; FONT-SIZE: 6.5pt;"><b><i>Calendar Year Returns</i></b></font></center> 2009-06-30 0.1261 <font style="font-family: serif; font-size: 10pt; "><b>Worst Quarter</b></font> 2011-09-30 <div style="display:none">~ http://www.troweprice.com/role/ScheduleAverageAnnualTotalReturnsTransposedTRowePriceInstitutionalHighYieldFund column period compact * ~</div> 0.004 0 0.0006 0.004 628 0.004 0.001 0.0006 0.005 505 0.0438 0.0638 0.1453 0.084 0.0712 0.0518 0.0498 0.065 0.0557 0.0487 <div style="display:none">~ http://www.troweprice.com/role/ScheduleExpenseExampleTransposedTRowePriceInstitutionalCorePlusFundFClass column period compact * ~</div> <font style="font-family: serif; font-size: 10pt; ">The fund seeks to maximize total return through income and capital appreciation. </font> 1.406 <font style="FONT-FAMILY: Sans-Serif; FONT-SIZE: 9.5pt; FONT-WEIGHT: bold">Principal Risks</font> <font style="FONT-FAMILY: Sans-Serif; FONT-SIZE: 9.5pt; FONT-WEIGHT: bold">Performance</font> <font style="font-family: serif; font-size: 10pt; ">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.
