Manager’s Letter
T. Rowe Price Institutional Long Duration Credit Fund
Dear Investor
In December, the U.S. Federal Reserve announced a 0.25 percentage point increase in its federal funds target rate. It was the first time since 2006 that the U.S. central bank raised rates, and since that increase, we have seen markets rise and fall in line with changing expectations for further tightening. We trimmed riskier positions in anticipation of the Fed’s move to ensure that the portfolio had a substantial allocation to high-quality bonds that could hold up well amid the volatility and shifting market expectations that followed the rate hike. Throughout the rest of the period, we continued to increase our allocation to more defensive and higher-rated credits.
Performance

During the 12-month period ended May 31, 2016, the fund returned 5.72%, compared with 5.24% for the Barclays U.S. Long Credit Bond Index. The fund’s share price rose during the 12-month reporting period to $10.44 from $10.33. Dividend income totaled $0.40 per share over the past 12 months. The fund’s 30-day SEC yield fell to 3.66%.

Market Environment

Volatility reigned over the last six months of the reporting period amid changing expectations about interest rate policy, oil price volatility, a slowing global economy, and mixed U.S. economic data. Uncertainty about the timing of future rate hikes also pressured bond prices.
Global headwinds have not bypassed the U.S. but have taken a somewhat smaller toll than in other developed markets. Weakness in commodity prices led energy and mining firms to cut back investment in plant and equipment spending. At the same time, credit spreads in the energy sector widened significantly, and Moody’s and Standard & Poor’s cut the credit ratings of many related issuers.
As the period ended, fears of a rapid economic slowdown had faded to some extent. In the U.S., generally solid employment growth continued to support consumer spending. Meanwhile, there were tentative signs of rising inflation, and import price deflation eased as the U.S. dollar fell from its January peak. The U.S. unemployment rate continued to trend lower, reaching 4.7% in May 2016. Corporate bond markets have benefited from some renewed optimism. Easing monetary policies in Europe and Japan set off a new round of bond buying by yield-hungry investors and resulted in a strong rally across the major bond sectors. A stabilization and rebound in oil prices also contributed to the positive tone toward the end of the reporting period.
Over the 12-month period, the yield on the 10-year U.S. Treasury note fell to 1.84% from 2.12%, and the U.S. Treasury yield curve continued to flatten as short-term yields increased while longer-maturity yields decreased. Fed rate hikes affect the prices of short-maturity debt more than longer-term bonds. (Bond prices and yields move in opposite directions.)
Portfolio Review

Overall, our underweight to and security selection within the energy sector boosted performance in relation to our Barclays benchmark. The sector was volatile as a result of fluctuations in commodity prices but rallied in the second half of the reporting period. Our allocation to higher-quality liquid names, such as Columbia Pipeline Group, Royal Dutch Shell, and Exxon Mobil, aided returns. (Please refer to the fund’s portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)
Security selection in the capital goods sector also helped results. Northrop Grumman debt performed well as the large aerospace and defense technology company’s stability and strong credit fundamentals led it to outperform amid the volatility. Our holdings in Harris, which makes satellite communications equipment for businesses and government, also helped returns. The company’s bonds performed well as its longer-term credit profile improved following its February acquisition of Exelis, which makes a range of technology and surveillance products. In the U.S. diversified banking segment, our holdings of U.S. banks with large, well-diversified, solid balance sheets performed well after the Basel-based Financial Stability Board lowered global requirements for the amount of money the world’s top 30 banks must raise through long-term bonds in order to cover their costs in the event that they fail.
Our allocation to quasi-sovereign emerging markets bonds contributed to relative performance, while security selection detracted. Colombia’s state-run oil company, Ecopetrol, led the decline after Moody’s lowered the company’s standalone credit rating three notches in early 2016. Our holdings of debt issued by Mexico’s state-owned oil company Petroleos Mexicanos (PEMEX) also suffered from a Moody’s downgrade. Finally, our slight overweight to the basic materials sector hurt results as the segment suffered from slowing global growth prospects and a decline in commodity prices.
We expect to continue shifting into lower-risk assets. We have moved into some well-capitalized, higher-quality financial companies that, historically, have been able to withstand market corrections. We also consolidated our energy positions, selling riskier names and adding higher-conviction positions.

We believe that investment-grade corporate bonds are in a good position given the pressure on high yield bonds and emerging markets debt. We are finding value in the BBB rated non-commodity segment, where we had the largest percentage of our investments at the end of the reporting period. We expect to see flows into this segment from higher-risk areas of the fixed income market. In an environment where global rates are very low, foreign investors have increasingly moved into U.S. investment-grade credit in their search for higher yields.
While broad market liquidity remains a concern, declining liquidity can also create opportunities for long-term fixed income investors. Less liquid bonds can be attractive when issuers are fundamentally sound and investors are adequately compensated with attractive yields.
At the end of May, 92% of the portfolio’s net assets was invested in investment-grade bonds and cash, and 3% was invested in BB rated bonds. In addition to our U.S. corporate holdings, approximately 7% of the portfolio was invested in non-U.S. credits. The remainder of the portfolio was invested in U.S. government bonds and reserves.
We have changed the fund’s rating methodology to align with that of its benchmark to better reflect the credit quality of the fund’s assets.
Outlook
We believe the U.S. is in the late stage of the credit cycle, which is characterized by increasingly leveraged balance sheets, deterioration in credit metrics, and uneven investor demand. Concerns about elevated levels of supply, global macroeconomic volatility, commodity price instability, and slowing global growth will likely persist and weigh on the corporate bond markets. Despite the recent oil rebound, commodity prices remain low relative to their averages over the last decade, and we intend to remain selective as a result. Furthermore, investor demand could face periodic challenges from widespread risk aversion if underwhelming global economic growth persists.
Even though the Fed’s pace of rate normalization is likely to be gradual and measured, we believe the general direction of the Fed’s tightening efforts will keep upward pressure on yields, particularly on the shorter-maturity segment of the yield curve.
Healthy demand for corporate bonds, potentially supported by spillover effects from the European Central Bank’s purchases of European corporate debt, should continue, while valuations still appear fair. In keeping with our long-term strategy, we believe identifying lower-rated, asset-rich companies that provide the portfolio with a notable yield and spread advantage over the benchmark can be a significant driver of positive relative returns.
As always, we will continue to search for value and seek out securities offering reasonable yields without taking on an inordinate level of risk. We remain committed to a risk-conscious, fundamentally based investment approach and long-term perspective.
Thank you for investing with T. Rowe Price.
Respectfully submitted,

Risks of Fixed Income Investing |
Bonds are subject to interest rate risk (the decline in bond prices that usually accompanies a rise in interest rates) and credit risk (the chance that any fund holding could have its credit rating downgraded or that a bond issuer will default by failing to make timely payments of interest or principal), potentially reducing the fund’s income level and share price. High yield corporate bonds could have greater price declines than funds that invest primarily in high-quality bonds. Companies issuing high yield bonds are not as strong financially as those with higher credit ratings, so the bonds are usually considered speculative investments.
Barclays U.S. Long Credit Bond Index: A measure of corporate fixed income securities that are primarily rated investment grade (Baa by Moody’s Investors Service and BBB by Standard & Poor’s).
Duration: A measure of a bond fund’s sensitivity to changes in interest rates. For example, a fund with a duration of six years would fall about 6% in price in response to a one-percentage-point rise in interest rates, and vice versa.
Fed funds rate: The interest rate charged on overnight loans of reserves by one financial institution to another in the United States. The Federal Reserve sets a target federal funds rate to affect the direction of interest rates.
Gross domestic product (GDP): The total market value of all goods and services produced in a country in a given year.
Lipper averages: The averages of available mutual fund performance returns for specified time periods in categories defined by Lipper Inc.
SEC yield (30-day): A method of calculating a fund’s yield that assumes all portfolio securities are held until maturity. Yield will vary and is not guaranteed.
Weighted average maturity: A measure of a fund’s interest rate sensitivity. In general, the longer the average maturity, the greater the fund’s sensitivity to interest rate changes. The weighted average maturity may take into account the interest rate readjustment dates for certain securities.
Yield curve: A graphic depiction of the relationship between yields and maturity dates for a set of similar securities. A security with a longer maturity usually has a higher yield. If a short-term security offers a higher yield, then the curve is said to be “inverted.” If short- and long-term bonds are offering equivalent yields, then the curve is said to be “flat.”
Performance and Expenses
T. Rowe Price Institutional Long Duration Credit Fund
This chart shows the value of a hypothetical $1 million investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The result is compared with benchmarks, which may include a broad-based market index and a peer group average or index. Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.


Fund Expense Example
As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period.
Actual Expenses
The first line of the following table (Actual) provides information about actual account values and actual expenses. You may use the information on this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.
Hypothetical Example for Comparison Purposes
The information on the second line of the table (Hypothetical) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.
You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

Notes to Financial Statements
T. Rowe Price Institutional Long Duration Credit Fund
May 31, 2016
T. Rowe Price Institutional Income Funds, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The Institutional Long Duration Credit Fund (the fund) is a diversified, open-end management investment company established by the corporation. The fund incepted on June 3, 2013. The fund seeks to provide high income.
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
Basis of Preparation The fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 (ASC 946). The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), including, but not limited to, ASC 946. GAAP requires the use of estimates made by management. Management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the accompanying financial statements may differ from the value ultimately realized upon sale or maturity.
Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions, if any, are reflected as realized gain/loss. Dividend income and capital gain distributions are recorded on the ex-dividend date. Income tax-related interest and penalties, if incurred, would be recorded as income tax expense. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Income distributions are declared daily and paid monthly. Distributions to shareholders are recorded on the ex-dividend date. Capital gain distributions, if any, are generally declared and paid by the fund annually.
New Accounting Guidance In May 2015, FASB issued ASU No. 2015-07, Fair Value Measurement (Topic 820), Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). The ASU removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient and amends certain disclosure requirements for such investments. The ASU is effective for interim and annual reporting periods beginning after December 15, 2015. Adoption will have no effect on the fund’s net assets or results of operations.
NOTE 2 - VALUATION
The fund’s financial instruments are valued and its net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business.
Fair Value The fund’s financial instruments are reported at fair value, which GAAP defines as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The T. Rowe Price Valuation Committee (the Valuation Committee) has been established by the fund’s Board of Directors (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the Board and has representation from legal, portfolio management and trading, operations, risk management, and the fund’s treasurer.
Various valuation techniques and inputs are used to determine the fair value of financial instruments. GAAP establishes the following fair value hierarchy that categorizes the inputs used to measure fair value:
Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date
Level 2 – inputs other than Level 1 quoted prices that are observable, either directly or indirectly (including, but not limited to, quoted prices for similar financial instruments in active markets, quoted prices for identical or similar financial instruments in inactive markets, interest rates and yield curves, implied volatilities, and credit spreads)
Level 3 – unobservable inputs
Observable inputs are developed using market data, such as publicly available information about actual events or transactions, and reflect the assumptions that market participants would use to price the financial instrument. Unobservable inputs are those for which market data are not available and are developed using the best information available about the assumptions that market participants would use to price the financial instrument. GAAP requires valuation techniques to maximize the use of relevant observable inputs and minimize the use of unobservable inputs. When multiple inputs are used to derive fair value, the financial instrument is assigned to the level within the fair value hierarchy based on the lowest-level input that is significant to the fair value of the financial instrument. Input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level but rather the degree of judgment used in determining those values.
Valuation Techniques Debt securities generally are traded in the over-the-counter (OTC) market. Securities with remaining maturities of one year or more at the time of acquisition are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers the yield or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Securities with remaining maturities of less than one year at the time of acquisition generally use amortized cost in local currency to approximate fair value. However, if amortized cost is deemed not to reflect fair value or the fund holds a significant amount of such securities with remaining maturities of more than 60 days, the securities are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service. Generally, debt securities are categorized in Level 2 of the fair value hierarchy; however, to the extent the valuations include significant unobservable inputs, the securities would be categorized in Level 3.
Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation and are categorized in Level 1 of the fair value hierarchy. Financial futures contracts are valued at closing settlement prices and are categorized in Level 1 of the fair value hierarchy. Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value.
Thinly traded financial instruments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Valuation Committee. The objective of any fair value pricing determination is to arrive at a price that could reasonably be expected from a current sale. Financial instruments fair valued by the Valuation Committee are primarily private placements, restricted securities, warrants, rights, and other securities that are not publicly traded.
Subject to oversight by the Board, the Valuation Committee regularly makes good faith judgments to establish and adjust the fair valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of troubled or thinly traded debt instruments, the Valuation Committee considers a variety of factors, which may include, but are not limited to, the issuer’s business prospects, its financial standing and performance, recent investment transactions in the issuer, strategic events affecting the company, market liquidity for the issuer, and general economic conditions and events. In consultation with the investment and pricing teams, the Valuation Committee will determine an appropriate valuation technique based on available information, which may include both observable and unobservable inputs. The Valuation Committee typically will afford greatest weight to actual prices in arm’s length transactions, to the extent they represent orderly transactions between market participants, transaction information can be reliably obtained, and prices are deemed representative of fair value. However, the Valuation Committee may also consider other valuation methods such as a discount or premium from market value of a similar, freely traded security of the same issuer; discounted cash flows; yield to maturity; or some combination. Fair value determinations are reviewed on a regular basis and updated as information becomes available, including actual purchase and sale transactions of the issue. Because any fair value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions, and fair value prices determined by the Valuation Committee could differ from those of other market participants. Depending on the relative significance of unobservable inputs, including the valuation technique(s) used, fair valued securities may be categorized in Level 2 or 3 of the fair value hierarchy.
Valuation Inputs The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on May 31, 2016:

NOTE 3 - DERIVATIVE INSTRUMENTS
During the year ended May 31, 2016, the fund invested in derivative instruments. As defined by GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variable; it requires little or no initial investment and permits or requires net settlement. The fund invests in derivatives only if the expected risks and rewards are consistent with its investment objectives, policies, and overall risk profile, as described in its prospectus and Statement of Additional Information. The fund may use derivatives for a variety of purposes, such as seeking to hedge against declines in principal value, increase yield, invest in an asset with greater efficiency and at a lower cost than is possible through direct investment, or to adjust portfolio duration and credit exposure. The risks associated with the use of derivatives are different from, and potentially much greater than, the risks associated with investing directly in the instruments on which the derivatives are based. The fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover its settlement obligations under open derivative contracts.
The fund values its derivatives at fair value and recognizes changes in fair value currently in its results of operations. Accordingly, the fund does not follow hedge accounting, even for derivatives employed as economic hedges. Generally, the fund accounts for its derivatives on a gross basis. It does not offset the fair value of derivative liabilities against the fair value of derivative assets on its financial statements, nor does it offset the fair value of derivative instruments against the right to reclaim or obligation to return collateral. As of May 31, 2016, the fund held interest rate futures with cumulative unrealized gain of $11,000 and cumulative unrealized loss of $5,000; the value reflected on the accompanying Statement of Assets and Liabilities is the related unsettled variation margin.
Additionally, during the year ended May 31, 2016, the fund recognized $203,000 of realized gain on Futures and a $(3,000) change in unrealized gain/loss on Futures related to its investments in interest rate derivatives; such amounts are included on the accompanying Statement of Operations.
Counterparty Risk and Collateral The fund invests in exchange-traded or centrally cleared derivative contracts, such as futures, exchange-traded options, and centrally cleared swaps. Counterparty risk on such derivatives is minimal because the clearinghouse provides protection against counterparty defaults. For futures and centrally cleared swaps, the fund is required to deposit collateral in an amount equal to a certain percentage of the contract value (margin requirement), and the margin requirement must be maintained over the life of the contract. Each clearing broker, in its sole discretion, may adjust the margin requirements applicable to the fund.
Collateral may be in the form of cash or debt securities issued by the U.S. government or related agencies. Cash and currencies posted by the fund are reflected as cash deposits in the accompanying financial statements and generally are restricted from withdrawal by the fund; securities posted by the fund are so noted in the accompanying Portfolio of Investments; both remain in the fund’s assets. As of May 31, 2016, cash of $63,000 had been posted by the fund for exchange-traded and/or centrally cleared derivatives.
Futures Contracts The fund is subject to interest rate risk in the normal course of pursuing its investment objectives and uses futures contracts to help manage such risk. The fund may enter into futures contracts to manage exposure to interest rate and yield curve movements, security prices, foreign currencies, credit quality, and mortgage prepayments; as an efficient means of adjusting exposure to all or part of a target market; to enhance income; as a cash management tool; or to adjust portfolio duration and credit exposure. A futures contract provides for the future sale by one party and purchase by another of a specified amount of a specific underlying financial instrument at an agreed-upon price, date, time, and place. The fund currently invests only in exchange-traded futures, which generally are standardized as to maturity date, underlying financial instrument, and other contract terms. Payments are made or received by the fund each day to settle daily fluctuations in the value of the contract (variation margin), which reflect changes in the value of the underlying financial instrument. Variation margin is recorded as unrealized gain or loss until the contract is closed. The value of a futures contract included in net assets is the amount of unsettled variation margin; net variation margin receivable is reflected as an asset, and net variation margin payable is reflected as a liability on the accompanying Statement of Assets and Liabilities. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values and/or interest rates, and potential losses in excess of the fund’s initial investment. During the year ended May 31, 2016, the volume of the fund’s activity in futures, based on underlying notional amounts, was generally between 8% and 12% of net assets.
NOTE 4 - OTHER INVESTMENT TRANSACTIONS
Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund’s prospectus and Statement of Additional Information.
Restricted Securities The fund may invest in securities that are subject to legal or contractual restrictions on resale. Prompt sale of such securities at an acceptable price may be difficult and may involve substantial delays and additional costs.
Other Purchases and sales of portfolio securities other than short-term and U.S. government securities aggregated $17,652,000 and $12,405,000, respectively, for the year ended May 31, 2016. Purchases and sales of U.S. government securities aggregated $5,949,000 and $5,068,000, respectively, for the year ended May 31, 2016.
NOTE 5 - FEDERAL INCOME TAXES
No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its taxable income and gains. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character but are not adjusted for temporary differences.
The fund files U.S. federal, state, and local tax returns as required. The fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.
Reclassifications between income and gain relate primarily to the recharacterization of distributions. For the year ended May 31, 2016, the following reclassifications were recorded to reflect tax character (there was no impact on results of operations or net assets):

Distributions during the years ended May 31, 2016 and May 31, 2015, were characterized for tax purposes as follows:

At May 31, 2016, the tax-basis cost of investments and components of net assets were as follows:

The difference between book-basis and tax-basis net unrealized appreciation (depreciation) is attributable to the deferral of losses from certain derivative contracts for tax purposes. The fund intends to retain realized gains to the extent of available capital loss carryforwards. Net realized capital losses may be carried forward indefinitely to offset future realized capital gains.
NOTE 6 - RELATED PARTY TRANSACTIONS
The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). The investment management and administrative agreement between the fund and Price Associates provides for an all-inclusive annual fee equal to 0.45% of the fund’s average daily net assets. The fee is computed daily and paid monthly. The all-inclusive fee covers investment management, shareholder servicing, transfer agency, accounting, and custody services provided to the fund, as well as fund directors’ fees and expenses. Interest, taxes, brokerage commissions, and extraordinary expenses are paid directly by the fund.
The fund may invest in the T. Rowe Price Reserve Investment Fund, the T. Rowe Price Government Reserve Investment Fund, or the T. Rowe Price Short-Term Reserve Fund (collectively, the Price Reserve Investment Funds), open-end management investment companies managed by Price Associates and considered affiliates of the fund. The Price Reserve Investment Funds are offered as short-term investment options to mutual funds, trusts, and other accounts managed by Price Associates or its affiliates and are not available for direct purchase by members of the public. The Price Reserve Investment Funds pay no investment management fees.
As of May 31, 2016, T. Rowe Price Group, Inc., or its wholly owned subsidiaries owned 1,500,000 shares of the fund, representing 43% of the fund’s net assets.
The fund may participate in securities purchase and sale transactions with other funds or accounts advised by Price Associates (cross trades), in accordance with procedures adopted by the fund’s Board and Securities and Exchange Commission rules, which require, among other things, that such purchase and sale cross trades be effected at the independent current market price of the security. During the year ended May 31, 2016, the fund had no purchases or sales cross trades with other funds or accounts advised by Price Associates.
Report of Independent Registered Public Accounting Firm
To the Board of Directors of T. Rowe Price Institutional Income Funds, Inc. and
Shareholders of T. Rowe Price Institutional Long Duration Credit Fund
In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the T. Rowe Price Institutional Long Duration Credit Fund (one of the portfolios comprising T. Rowe Price Institutional Income Funds, Inc., hereafter referred to as the “Fund”) at May 31, 2016, the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at May 31, 2016 by correspondence with the custodian and brokers, and confirmation of the underlying fund by correspondence with the transfer agent, provide a reasonable basis for our opinion.

Approval of Investment Management Agreement |
On March 11, 2016, the fund’s Board of Directors (Board), including a majority of the fund’s independent directors, approved the continuation of the investment management agreement (Advisory Contract) between the fund and its investment advisor, T. Rowe Price Associates, Inc. (Advisor). In connection with its deliberations, the Board requested, and the Advisor provided, such information as the Board (with advice from independent legal counsel) deemed reasonably necessary. The Board considered a variety of factors in connection with its review of the Advisory Contract, also taking into account information provided by the Advisor during the course of the year, as discussed below:
Services Provided by the Advisor
The Board considered the nature, quality, and extent of the services provided to the fund by the Advisor. These services included, but were not limited to, directing the fund’s investments in accordance with its investment program and the overall management of the fund’s portfolio, as well as a variety of related activities such as financial, investment operations, and administrative services; compliance; maintaining the fund’s records and registrations; and shareholder communications. The Board also reviewed the background and experience of the Advisor’s senior management team and investment personnel involved in the management of the fund, as well as the Advisor’s compliance record. The Board concluded that it was satisfied with the nature, quality, and extent of the services provided by the Advisor.
Investment Performance of the Fund
The Board reviewed the fund’s three-month, one-year, and annualized since-inception returns, and compared these returns with a wide variety of comparable performance measures and market data, including those supplied by Lipper and Morningstar, which are independent providers of mutual fund data.
On the basis of this evaluation and the Board’s ongoing review of investment results, and factoring in the relative market conditions during certain of the performance periods and the fund’s relatively limited operating history, the Board concluded that the fund’s performance was satisfactory.
Costs, Benefits, Profits, and Economies of Scale
The Board reviewed detailed information regarding the revenues received by the Advisor under the Advisory Contract and other benefits that the Advisor (and its affiliates) may have realized from its relationship with the fund, including any research received under “soft dollar” agreements and commission-sharing arrangements with broker-dealers. The Board considered that the Advisor may receive some benefit from soft-dollar arrangements pursuant to which research is received from broker-dealers that execute the applicable fund’s portfolio transactions. The Board received information on the estimated costs incurred and profits realized by the Advisor from managing T. Rowe Price mutual funds. While the Board did not review information regarding profits realized from managing the fund in particular because the fund had either not achieved sufficient portfolio asset size or not recognized sufficient revenues to produce meaningful profit margin percentages, the Board concluded that the Advisor’s profits were reasonable in light of the services provided to the T. Rowe Price funds.
The Board also considered whether the fund benefits under the fee levels set forth in the Advisory Contract from any economies of scale realized by the Advisor. The Board noted that, under the Advisory Contract, the fund pays the Advisor a single fee, or all-inclusive management fee, which is based on the fund’s average daily net assets. The all-inclusive management fee includes investment management services and provides for the Advisor to pay all of the fund’s ordinary, recurring operating expenses except for interest, taxes, portfolio transaction fees, and any nonrecurring extraordinary expenses that may arise. The Board concluded that, based on the profitability data it reviewed and consistent with this all-inclusive management fee structure, the Advisory Contract provided for a reasonable sharing of any benefits from economies of scale with the fund.
Fees
The Board was provided with information regarding industry trends in management fees and expenses, and the Board reviewed the fund’s management fee rate and total expense ratio in comparison with fees and expenses of other comparable funds based on information and data supplied by Lipper. For these purposes, the Board assumed that the fund’s management fee rate was equal to the all-inclusive management fee rate less the fund’s actual operating expenses, and the total expense ratio was equal to the all-inclusive management fee rate. The information provided to the Board indicated that the fund’s management fee rate and total expense ratio were below the median for comparable funds.
The Board also reviewed the fee schedules for institutional accounts (including subadvised mutual funds) and private accounts with similar mandates that are advised or subadvised by the Advisor and its affiliates. Management provided the Board with information about the Advisor’s responsibilities and services provided to subadvisory and other institutional account clients, including information about how the requirements and economics of the institutional business differ from those of the Advisor’s proprietary mutual fund business. The Board considered information showing that the Advisor’s proprietary mutual fund business is generally more complex from a business and compliance perspective than its institutional account business, and considered various other relevant factors, including the broader scope of operations and oversight, more extensive shareholder communication infrastructure, greater asset flows, heightened business risks, and differences in applicable laws and regulations associated with the Advisor’s proprietary mutual fund business. In assessing the reasonableness of the fund’s management fee rate, the Board considered the differences in the nature of the services required for the Advisor to manage its proprietary mutual fund business versus managing a discrete pool of assets as a subadvisor to another institution’s mutual fund or for another institutional account, and the degree to which the Advisor performs significant additional services and assumes greater risk in managing the fund and other T. Rowe Price mutual funds than it does for institutional account clients.
On the basis of the information provided and the factors considered, the Board concluded that the fees paid by the fund under the Advisory Contract are reasonable.
Approval of the Advisory Contract
As noted, the Board approved the continuation of the Advisory Contract. No single factor was considered in isolation or to be determinative to the decision. Rather, the Board concluded, in light of a weighting and balancing of all factors considered, that it was in the best interests of the fund and its shareholders for the Board to approve the continuation of the Advisory Contract (including the fees to be charged for services thereunder). The independent directors were advised throughout the process by independent legal counsel.

Item 2. Code of Ethics.
The registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, applicable to its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of this code of ethics is filed as an exhibit to this Form N-CSR. No substantive amendments were approved or waivers were granted to this code of ethics during the period covered by this report.
Item 3. Audit Committee Financial Expert.
The registrant’s Board of Directors/Trustees has determined that Mr. Bruce W. Duncan qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. Duncan is considered independent for purposes of Item 3 of Form N-CSR.
Item 4. Principal Accountant Fees and Services.
(a) – (d) Aggregate fees billed for the last two fiscal years for professional services rendered to, or on behalf of, the registrant by the registrant’s principal accountant were as follows:

Audit fees include amounts related to the audit of the registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements and specifically include the issuance of a report on internal controls and, if applicable, agreed-upon procedures related to fund acquisitions. Tax fees include amounts related to services for tax compliance, tax planning, and tax advice. The nature of these services specifically includes the review of distribution calculations and the preparation of Federal, state, and excise tax returns. All other fees include the registrant’s pro-rata share of amounts for agreed-upon procedures in conjunction with service contract approvals by the registrant’s Board of Directors/Trustees.
(e)(1) The registrant’s audit committee has adopted a policy whereby audit and non-audit services performed by the registrant’s principal accountant for the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant require pre-approval in advance at regularly scheduled audit committee meetings. If such a service is required between regularly scheduled audit committee meetings, pre-approval may be authorized by one audit committee member with ratification at the next scheduled audit committee meeting. Waiver of pre-approval for audit or non-audit services requiring fees of a de minimis amount is not permitted.
(2) No services included in (b) – (d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.
(f) Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees.
(g) The aggregate fees billed for the most recent fiscal year and the preceding fiscal year by the registrant’s principal accountant for non-audit services rendered to the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant were $2,409,000 and $2,554,000, respectively.
(h) All non-audit services rendered in (g) above were pre-approved by the registrant’s audit committee. Accordingly, these services were considered by the registrant’s audit committee in maintaining the principal accountant’s independence.
