International equities delivered positive returns during the six months ended April 30, 2012, amid ongoing political and economic turmoil in the eurozone and sluggish economic growth in the U.S. The U.S. presidential election, the strength of the economy, and the unfolding of events in Europe are likely to dominate global financial markets in the months ahead.

The fund returned 3.80% during the six-month period ended April 30, 2012, compared with 2.84% for the FTSE All World Developed ex North America Index. The fund gives shareholders exposure to non-U.S. stocks by seeking to match the performance of the FTSE index.

Europe foundered on the shoals of high unemployment, which rose above 10% even in some of the eurozone’s stronger economies, and contracting economic activity. All eyes—indeed, the eyes of the entire global financial and investment community—focused on two key elections on May 6 after the close of the reporting period. France commanded center stage with a polarizing runoff between French President Nicolas Sarkozy and his Socialist challenger, François Hollande. Hollande stated explicitly during the campaign that Germany should not be dictating fiscal policy to France—or to the rest of Europe, for that matter. He presented, instead, a so-called growth compact of reduced cuts in government spending and a continuation of the social welfare programs that have proven unsustainable over the long haul.

In Greece, a plethora of left- and right-wing parties challenged the establishment powers that have dominated Greek politics for decades. A measure of investors’ confidence in Greece’s ability to resolve the dilemma was the breathtaking 21% yield on Greek government bonds. It is hardly encouraging that Germany, the eurozone’s strongest economy relatively speaking, is itself tottering on the brink of recession and is unable to keep playing the role of Europe’s bank of final resort.

At the end of the day, the election results were somewhat disquieting. Hollande bested Sarkozy in France, and an unwieldy assortment of antiestablishment forces prevailed in Greece. Hollande and German Chancellor Angela Merkel seem poised to embark on a bad political and economic marriage that is likely to worsen over time with their diametrically opposed views on how to resurrect the European economy. The main question is whether the two leaders can come to terms and guarantee the survival of a united eurozone in its present form or whether its eventual dissolution is all but inevitable. Investors were less than thrilled by the results and sent both the euro and global equities markets sliding in the wake of the elections.

Japan was still reeling from the horrific shockwaves of earthquakes, tsunamis, and extensive damage to the country’s nuclear generating capacity. China, the major economic power in Asia, announced that growth has slowed significantly, which threatened to derail the developing economies in the region along with global growth in general. Through it all, most regions of the world managed to generate positive stock market returns during the past six months. France was the weakest in the developed world, while Brazil was a laggard in the emerging markets sphere.

The index’s major markets include the UK, Japan, and developed countries in Europe and the Pacific Rim. It is constructed by sorting the market in each country in the index by industry groups and targeting a significant portion of the stocks in these groups for inclusion. The fund attempts to replicate the index by investing in stocks in proportion to their index weighting.

At the end of April, Europe represented 60% of net assets, with Japan and the Pacific Rim constituting most of the balance (see the Geographic Diversification pie chart for a breakdown of regional allocations). Financial stocks were the largest sector at 21.3% of assets, followed by industrials and business services (12.5%), consumer staples (11.1%), consumer discretionary (10.9%), materials (9.9%), health care (8.5%), energy (7.9%), and other sectors making up the balance.

Information technology stocks contributed most to international equity results during the past six months, followed by reasonably good performance from financials and industrials and business services. Your fund was well represented in all three sectors, with key holdings in South Korea’s Samsung Electronics and the UK’s Vodafone; the UK’s HSBC, one of the world’s largest banking and financial services companies; and Germany’s Siemens, a global powerhouse in electronics and electrical engineering operating in the industrial, energy, and health care sectors. (Please refer to the fund’s portfolio of investments for a detailed list of holdings and the amount each represents in the portfolio.)

The weakest groups during our reporting period were energy and consumer discretionary. Our major positions in those areas included the UK’s Royal Dutch Shell and BP in energy and British American Tobacco and Japan’s Toyota Motor in the latter category. Energy stocks came under pressure late in the period as oil prices peaked and fell from their earlier highs, while weak demand from developed world consumers hampered discretionary purchases.

At the end of April, the portfolio contained a broad cross section of stocks from various sectors and countries. In addition to the companies already mentioned, other top holdings included Switzerland’s Nestle and Novartis, and Australia’s BHP Billiton. The fund is structured to mirror its benchmark index and give investors exposure to the major international markets in the developed world.

Our outlook for stocks in the developed non-U.S. markets over the rest of 2012 is clouded by concerns about events evolving in the eurozone and the potential growth rates for companies in the region. The risks in Europe have intensified in the wake of the recent elections, and stock valuations are less appealing than they were six months ago. In the U.S.—where we do not invest—we have concerns about how investor sentiment will be affected by the runup to the fall elections. The debate about the direction of U.S. fiscal policy in 2013 will only grow more heated through the summer and into the early fall of this year, and any outcomes are likely to affect international equity markets as well as those in the U.S.

Japan presents other risks, as both top-down and bottom-up issues serve as a barrier. The strength of the yen versus other major currencies is problematic for Japan’s major companies, which depend largely on exports for earnings growth. In addition, Japanese corporate culture is not often focused on adopting measures to maximize return-on-capital growth. Growth in the Pacific Rim countries outside Japan could be affected by a slowdown in China’s economic output. There is little question that growth in the region has been weakening, but inflation risks are receding and governments have begun to loosen monetary policy as a result, which should stimulate further economic growth.

As always, shareholders should be aware that we do not make investment decisions based on market forecasts or prospects for individual companies. Rather, our mission is to provide investors with low-cost exposure to non-U.S. equities through a diversified portfolio designed to replicate the performance of our benchmark index in all market conditions. It is important to maintain a long-term perspective and include an allocation to foreign securities as an integral part of a diversified investment portfolio.

The committee cochairmen have day-to-day responsibility for managing the portfolio and work with committee members in developing and executing the fund’s investment program.

Funds that invest overseas generally carry more risk than funds that invest strictly in U.S. assets. Funds investing in a single country or in a limited geographic region tend to be riskier than more diversified funds. Risks can result from varying stages of economic and political development; differing regulatory environments, trading days, and accounting standards; and higher transaction costs of non-U.S. markets. Non-U.S. investments are also subject to currency risk, or a decline in the value of a foreign currency versus the U.S. dollar, which reduces the dollar value of securities denominated in that currency.

FTSE All World Developed ex North America Index: A broadly diversified stock market index based on the investable market capitalization of more than 1,000 predominantly larger companies listed in 21 countries. The index’s major markets include the UK, Japan, and developed countries in Europe and the Pacific Rim.

Gross domestic product (GDP): The total market value of all goods and services produced in a country in a given year.

This chart shows the value of a hypothetical $10,000 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.

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.

Note: T. Rowe Price charges an account service fee that is not included in the accompanying table. The account service fee is charged on a quarterly basis, usually during the last week of a calendar quarter, and applies to accounts with balances below $10,000 on the day of the assessment. The fee is charged to accounts that fall below $10,000 for any reason, including market fluctuations, redemptions, or exchanges. When an account with less than $10,000 is closed either through redemption or exchange, the fee is charged and deducted from the proceeds. The fee applies to IRAs but not to retirement plans directly registered with T. Rowe Price Services or accounts maintained by intermediaries through NSCC^® Networking. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds.

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.

T. Rowe Price International Index Fund, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The International Equity Index Fund (the fund) is a diversified, open-end management investment company established by the corporation. The fund commenced operations on November 30, 2000. The fund seeks to match the performance of the FTSE^® International Limited (“FTSE”) All World Developed ex North America Index.

Basis of Preparation The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), which require 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 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. Distributions to shareholders are recorded on the ex-dividend date. Income distributions are declared and paid annually. Capital gain distributions, if any, are generally declared and paid by the fund annually.

Currency Translation Assets, including investments, and liabilities denominated in foreign currencies are translated into U.S. dollar values each day at the prevailing exchange rate, using the mean of the bid and asked prices of such currencies against U.S. dollars as quoted by a major bank. Purchases and sales of securities, income, and expenses are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction. The effect of changes in foreign currency exchange rates on realized and unrealized security gains and losses is reflected as a component of security gains and losses.

Credits Credits are earned on the fund’s temporarily uninvested cash balances held at the custodian and such credits reduce the amount paid by the manager for custody of the fund’s assets. In order to pass the benefit of custody credits to the fund, the manager has voluntarily reduced its investment management and administrative expense in the accompanying financial statements.

Redemption Fees A 2% fee is assessed on redemptions of fund shares held for 90 days or less to deter short-term trading and to protect the interests of long-term shareholders. Redemption fees are withheld from proceeds that shareholders receive from the sale or exchange of fund shares. The fees are paid to the fund and are recorded as an increase to paid-in capital. The fees may cause the redemption price per share to differ from the net asset value per share.

New Accounting Pronouncements In May 2011, the Financial Accounting Standards Board (FASB) issued amended guidance to align fair value measurement and disclosure requirements in U.S. GAAP with International Financial Reporting Standards. The guidance is effective for fiscal years and interim periods beginning on or after December 15, 2011. Adoption will have no effect on net assets or results of operations.

In December 2011, the FASB issued amended guidance to enhance disclosure for offsetting assets and liabilities. The guidance is effective for fiscal years and interim periods beginning on or after January 1, 2013; adoption will have no effect on the fund’s net assets or results of operations.

The fund’s financial instruments are reported at fair value as defined by GAAP. The fund determines the values of its assets and liabilities and computes its net asset value per share at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day that the NYSE is open for business.

Valuation Methods Equity securities listed or regularly traded on a securities exchange or in the over-the-counter (OTC) market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made, except for OTC Bulletin Board securities, which are valued at the mean of the latest bid and asked prices. A security that is listed or traded on more than one exchange is valued at the quotation on the exchange determined to be the primary market for such security. Listed securities not traded on a particular day are valued at the mean of the latest bid and asked prices for domestic securities and the last quoted sale price for international securities. Debt 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.

Investments in mutual funds are valued at the mutual fund’s closing net asset value per share on the day of valuation. Financial futures contracts are valued at closing settlement prices.

Other investments, including restricted securities and private placements, and those financial instruments 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 T. Rowe Price Valuation Committee, established by the fund’s Board of Directors (the Board). Subject to oversight by the Board, the Valuation Committee develops pricing-related policies and procedures and approves all fair-value determinations. The Valuation Committee regularly makes good faith judgments, using a wide variety of sources and information, to establish and adjust valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of private-equity instruments, the Valuation Committee considers a variety of factors, including the company’s business prospects, its financial performance, strategic events impacting the company, relevant valuations of similar companies, new rounds of financing, and any negotiated transactions of significant size between other investors in the company. Because any fair-value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions.

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted under the circumstances described below. If the fund determines that developments between the close of a foreign market and the close of the NYSE will, in its judgment, materially affect the value of some or all of its portfolio securities, the fund will adjust the previous closing prices to reflect what it believes to be the fair value of the securities as of the close of the NYSE. In deciding whether it is necessary to adjust closing prices to reflect fair value, the fund reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U.S. markets that represent foreign securities and baskets of foreign securities. A fund may also fair value securities in other situations, such as when a particular foreign market is closed but the fund is open. The fund uses outside pricing services to provide it with closing prices and information to evaluate and/or adjust those prices. The fund cannot predict how often it will use closing prices and how often it will determine it necessary to adjust those prices to reflect fair value. As a means of evaluating its security valuation process, the fund routinely compares closing prices, the next day’s opening prices in the same markets, and adjusted prices. Additionally, trading in the underlying securities of the fund may take place in various foreign markets on certain days when the fund is not open for business and does not calculate a net asset value. As a result, net asset values may be significantly affected on days when shareholders cannot make transactions.

Valuation Inputs Various inputs are used to determine the value of the fund’s financial instruments. These inputs are summarized in the three broad levels listed below:

Level 2 – observable inputs other than Level 1 quoted prices (including, but not limited to, quoted prices for similar financial instruments, interest rates, prepayment speeds, and credit risk)

Observable inputs are those based on market data obtained from sources independent of the fund, and unobservable inputs reflect the fund’s own assumptions based on the best information available. The input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level. For example, non-U.S. equity securities actively traded in foreign markets generally are reflected in Level 2 despite the availability of closing prices because the fund evaluates and determines whether those closing prices reflect fair value at the close of the NYSE or require adjustment, as described above. The following table summarizes the fund’s financial instruments, based on the inputs used to determine their values on April 30, 2012:

Following is a reconciliation of the fund’s Level 3 holdings for the six months ended April 30, 2012. Gain (loss) reflects both realized and change in unrealized gain (loss) on Level 3 holdings during the period, if any, and is included on the accompanying Statement of Operations. The change in unrealized gain (loss) on Level 3 instruments held at April 30, 2012, totaled $(10,000) for the six months ended April 30, 2012.

During the six months ended April 30, 2012, 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 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. Investments in derivatives can magnify returns positively or negatively; however, the fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover the settlement obligations under its open derivative contracts.

The fund values its derivatives at fair value, as described below and in Note 2, 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. The fund does not offset the fair value of derivative instruments against the right to reclaim or obligation to return collateral. As of April 30, 2012, the fund held equity futures with cumulative unrealized loss of $33,000; the value reflected on the accompanying Statement of Assets and Liabilities is the related unsettled variation margin.

Additionally, during the six months ended April 30, 2012, the fund recognized $170,000 of realized gain on Futures and a $94,000 change in unrealized loss on Futures related to its investments in equity derivatives; such amounts are included on the accompanying Statement of Operations.

Counterparty risk related to exchange-traded derivatives, including futures and options contracts, is minimal because the exchange’s clearinghouse provides protection against defaults. Additionally, for exchange-traded derivatives, each broker, in its sole discretion, may change margin requirements applicable to the fund.

Futures Contracts The fund is subject to equity price 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 as an efficient means of maintaining liquidity while being invested in the market, to facilitate trading, and/or to reduce transaction costs. A futures contract provides for the future sale by one party and purchase by another of a specified amount of a particular 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. Upon entering into a futures contract, the fund is required to deposit with the broker cash or securities in an amount equal to a certain percentage of the contract value (initial margin deposit); the margin deposit must then be maintained at the established level over the life of the contract. Subsequent 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. At its election, the fund may also hold additional U.S. dollars and foreign currencies in an account with the broker to settle future variation margin obligations. All cash and currencies held by the broker for initial margin or future settlements are reflected as deposits on futures contracts on the accompanying Statement of Assets and Liabilities. 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, if any. 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 potential losses in excess of the fund’s initial investment. During the six months ended April 30, 2012, the fund’s exposure to futures, based on underlying notional amounts, was generally less than 1% of net assets.

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.

Repurchase Agreements All repurchase agreements are fully collateralized by U.S. government securities. Collateral is in the possession of the fund’s custodian or, for tri-party agreements, the custodian designated by the agreement. Although risk is mitigated by the collateral, the fund could experience a delay in recovering its value and a possible loss of income or value if the counterparty fails to perform in accordance with the terms of the agreement.

Securities Lending The fund lends its securities to approved brokers to earn additional income. It receives as collateral cash and U.S. government securities valued at 102% to 105% of the value of the securities on loan. Collateral is maintained over the life of the loan in an amount not less than the value of loaned securities as determined at the close of fund business each day; any additional collateral required due to changes in security values is delivered to the fund the next business day. Cash collateral is invested by the fund’s lending agent(s) in accordance with investment guidelines approved by management. Although risk is mitigated by the collateral, the fund could experience a delay in recovering its securities and a possible loss of income or value if the borrower fails to return the securities or if collateral investments decline in value. Securities lending revenue recognized by the fund consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower and compensation to the lending agent. In accordance with GAAP, investments made with cash collateral are reflected in the accompanying financial statements, but collateral received in the form of securities are not. On April 30, 2012, the value of cash collateral investments was $24,971,000, and the value of loaned securities was $23,350,000.

Other Purchases and sales of portfolio securities other than short-term securities aggregated $25,576,000 and $16,664,000, respectively, for the six months ended April 30, 2012.

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 amount and character of tax-basis distributions and composition of net assets are finalized at fiscal year-end; accordingly, tax-basis balances have not been determined as of the date of this report.

As a result of the Regulated Investment Company Modernization Act of 2010, net capital losses realized on or after November 1, 2011 (effective date) may be carried forward indefinitely to offset future realized capital gains; however, post-effective losses must be used before pre-effective capital loss carryforwards with expiration dates. Accordingly, it is possible that all or a portion of the fund’s pre-effective capital loss carryforwards could expire unused. The fund intends to retain realized gains to the extent of available capital loss carryforwards. As of October 31, 2011, the fund had $67,832,000 of available capital loss carryforwards, which expire as follows: $11,710,000 in fiscal 2016, $18,272,000 in fiscal 2017, $10,857,000 in fiscal 2018, and $26,993,000 in fiscal 2019.

At April 30, 2012, the cost of investments for federal income tax purposes was $404,287,000. Net unrealized loss aggregated $12,103,000 at period-end, of which $71,732,000 related to appreciated investments and $83,835,000 related to depreciated investments.

The fund is subject to foreign income taxes imposed by certain countries in which it invests. Acquisition of certain foreign currencies related to security transactions are also subject to tax. Additionally, capital gains realized by the fund upon disposition of securities issued in or by certain foreign countries are subject to capital gains tax imposed by those countries. All taxes are computed in accordance with the applicable foreign tax law, and, to the extent permitted, capital losses are used to offset capital gains. Taxes attributable to income are accrued by the fund as a reduction of income. Taxes incurred on the purchase of foreign currencies are recorded as realized loss on foreign currency transactions. Current and deferred tax expense attributable to net capital gains is reflected as a component of realized and/or change in unrealized gain/loss on securities in the accompanying financial statements. At April 30, 2012, the fund had no deferred tax liability attributable to foreign securities and no foreign capital loss carryforwards.

The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). Price Associates has entered into a subadvisory agreement with T. Rowe Price International Ltd, a wholly owned subsidiary of Price Associates, to provide investment advisory services to the fund; the subadvisory agreement provides that Price Associates may pay the subadvisor up to 60% of the management fee that Price Associates receives from the fund. The investment management and administrative agreement between the fund and Price Associates provides for an all-inclusive annual fee equal to 0.50% 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.

Additionally, the fund is one of several mutual funds in which certain college savings plans managed by Price Associates may invest. As approved by the fund’s Board of Directors, shareholder servicing costs associated with each college savings plan are allocated to the fund in proportion to the average daily value of its shares owned by the college savings plan. Shareholder servicing costs allocated to the fund are borne by Price Associates, pursuant to the fund’s all-inclusive fee agreement. At April 30, 2012, no shares of the fund were held by college savings plans.

The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe Price Government Reserve Investment Fund (collectively, the T. Rowe Price Reserve Investment Funds), open-end management investment companies managed by Price Associates and considered affiliates of the fund. The T. Rowe Price Reserve Investment Funds are offered as cash management options to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates and are not available for direct purchase by members of the public. The T. Rowe Price Reserve Investment Funds pay no investment management fees.

On March 6, 2012, the fund’s Board of Directors (Board) unanimously approved the continuation of the investment advisory agreement (Advisory Contract) between the fund and its investment advisor, T. Rowe Price Associates, Inc. (Advisor). The Board also unanimously approved the continuation of the investment subadvisory agreement (Subadvisory Contract) that the Advisor has entered into with T. Rowe Price International Ltd (Subadvisor) on behalf of the fund. The Board considered a variety of factors in connection with its review of the Advisory Contract and Subadvisory Contract, also taking into account information provided by the Advisor during the course of the year, as discussed below:

Services Provided by the Advisor and Subadvisor
The Board considered the nature, quality, and extent of the services provided to the fund by the Advisor and Subadvisor. 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, accounting, and administrative services; maintaining the fund’s records and registrations; and shareholder communications. The Board also reviewed the background and experience of the Advisor’s and Subadvisor’s senior management teams and investment personnel involved in the management of the fund. The Board concluded that it was satisfied with the nature, quality, and extent of the services provided by the Advisor and Subadvisor.

Investment Performance of the Fund
The Board reviewed the fund’s average annual total returns over the three-month and the 1-, 3-, 5-, and 10-year periods, as well as the fund’s year-by-year returns, and compared these returns with a wide variety of previously agreed upon 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, 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, including the Subadvisor) may have realized from its relationship with the fund, including research received under “soft dollar” agreements and commission-sharing arrangements with broker-dealers. The Board considered that the Advisor and Subadvisor 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. The Board also reviewed estimates of the gross profits realized from managing the fund in particular and the Board concluded that the Advisor’s profits were reasonable in light of the services provided to the fund.

The Board also considered whether the fund or other funds benefit 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 based on the fund’s average daily net assets that includes investment management services and provides for the Advisor to pay all expenses of the fund’s operations except for interest, taxes, portfolio transaction fees, and any nonrecurring extraordinary expenses that may arise. Under the Subadvisory Contract, the Advisor may pay the Subadvisor up to 60% of the advisory fee that the Advisor receives from the fund. The Board concluded that, based on the profitability data it reviewed and consistent with this single-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 single-fee structure 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 single fee less the fund’s operating expenses. The information provided to the Board indicated that the fund’s management fee rate was below the median for comparable funds and the fund’s total expense ratio was at or below the median for comparable funds.

The Board also reviewed the fee schedules for institutional accounts 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 institutional account clients that illustrated how the requirements and economies of the institutional business are fundamentally different from those of the mutual fund business. The information showed that the Advisor’s responsibilities for its institutional account business are more limited than its responsibilities for the fund and other T. Rowe Price mutual funds that it advises, and that the Advisor performs significant additional services and assumes greater risk for the fund and other T. Rowe Price mutual funds than it does for institutional account clients. On the basis of the information provided, the Board concluded that the fees paid by the fund under the Advisory Contract were reasonable.

Approval of the Advisory Contract and Subadvisory Contract
As noted, the Board approved the continuation of the Advisory Contract and Subadvisory Contract. No single factor was considered in isolation or to be determinative to the decision. Rather, the Board was assisted by the advice of independent legal counsel and 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 and Subadvisory Contract (including the fees to be charged for services thereunder).
