Manager’s Letter

Fellow Shareholders

International stocks advanced steadily from late 2010 through late February. Volatility returned in March, with stocks holding their ground early in the month, selling off sharply at mid-month, and then rallying impressively through the rest of the period. The unfolding tragedy in Japan, political turmoil in North Africa and the Middle East, and mixed economic signals all served to rattle investors before the market recovered. Developed markets in Europe were strong, enhanced by euro strength versus the U.S. dollar.

The fund returned 13.63% during the six-month period ended April 30, 2011, compared with 13.85% for the FTSE Developed ex North America Index. The fund gives shareholders exposure to non-U.S. stocks by seeking to match the performance of the FTSE Developed ex North America Index, a broadly diversified stock market index based on the investable market capitalization of more than 1,200 predominantly larger companies listed in over 20 countries.

MARKET REVIEW

International markets were broadly positive during the past six months, led by strong results in Europe. Headwinds emerged in late February as spreading political unrest in the Middle East and North Africa prompted investors to reduce their risk exposure. The markets were also rattled by a devastating earthquake that struck northeastern Japan on March 11, setting off a tsunami and nuclear crisis in the world’s third-largest economy. Early projections are that the Japanese economy will likely be slowed over the near term. Industrial production has suffered, and many automobile manufacturers in Japan and elsewhere will have production problems related to supply-chain issues. Rebuilding efforts are estimated to rise above $180 billion.

Results in the Pacific Rim were mixed. Japanese stocks plummeted in the aftermath of the disaster, then recovered some of their losses. Results across other Asian markets were generally strong as South Korea and Australia rallied. European stocks generated strong gains, but the debt crisis continued with several countries having their debt ratings downgraded. Portugal, Italy, Ireland, Greece, and Spain performed well despite concerns about their ability to manage their heavy debt burdens. European stock returns were enhanced by the strength of the euro versus the U.S. dollar.

Sector performance was positive across the board, with energy leading the way thanks to higher oil prices and the industrials and business services and telecommunication services sectors generating impressive results. Consumer staples and utilities lagged. Rising commodity prices weighed on the global economy. Oil prices are three times higher than they were in late 2008, and food prices hit a record high in February. As a result, inflation has become a major concern. China, India, and Europe have raised interest rates and launched other tightening measures. India’s inflation hit 8.3% in February, and the country has now lifted interest rates a total of eight times in the past year. Euro zone inflation climbed to an annualized rate of 2.4% in February, above analysts’ comfort level.

PORTFOLIO HIGHLIGHTS

The index’s major markets include the U.K., 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 weighting in the index.

At the end of April, Europe represented 62% of net assets, with Japan and the Pacific Rim constituting most of the balance (see the Geographic Diversification table for a breakdown of regional allocations). Financials was the largest sector at 23.3% of assets, followed by industrials and business services (12.8%), materials (11.0%), consumer discretionary (10.3%), consumer staples (9.5%), energy (7.9%), and health care (7.4%).

Some of the portfolio’s best-performing stocks were in the energy sector. As you can see from the Twenty-Five Largest Holdings table following this letter, the fund was well represented in the group. Our largest holding was the U.K.’s Royal Dutch Shell, with other major positions in BP of the U.K. and Total of France. Political unrest in the oil-rich Middle East and North Africa regions has pushed oil prices higher. Longer-term supply/demand dynamics also point to rising energy costs. (Please refer to the fund’s portfolio of investments for a detailed list of holdings and the amount each represents in the portfolio.)

Industrials and business services stocks also did well. One underperformer in the group, however, was Rolls-Royce. The stock lagged because of rising oil prices and flaws in its Trent 900 series engines. Initial response to a proposed acquisition with an engine manufacturer with a strong presence in marine and energy markets was lukewarm. The burgeoning cyclical upturn has made this area increasingly attractive, and the company remains a durable franchise with an attractive valuation that offers significant potential upside due to later-cycle business lines.

Among other winners over the past six months were consumer discretionary stocks that had delivered excellent returns in 2010. Switzerland-based Compagnie Financière Richemont, one of the world’s premier luxury goods companies with brands including Cartier and Van Cleef & Arpels, continued to deliver good results during the recent reporting period. Japan’s Honda and the U.K.’s Carnival also delivered strong results over the past six months.

Among our financials holdings, which represent the fund’s largest sector allocation, was Commonwealth Bank of Australia—the Australian dollar powered ahead of its U.S. counterpart in recent months, bolstering returns in currency terms. We also owned HSBC in the U.K., a major global banking and financial services company; Banco Santander of Spain; and Westpac Banking of Australia, which offers a broad array of business, financial, and investment services.

INVESTMENT OUTLOOK

We are optimistic about the medium-term prospects for international stocks, given their resiliency in the face of a highly volatile environment thus far in 2011. Despite a challenging macro environment, corporate earnings have been solid, while share buybacks and merger and acquisition activity are steadily increasing. International equities remain attractively valued in historical terms, particularly when compared with bonds, and corporate fundamentals are sound and improving. While the durability of healthy profit margins remains in question moving forward, we expect a positive economic trajectory throughout most of world.

We recognize that inflation concerns may be elevated in the near term, but we are comforted that most monetary authorities are taking the necessary actions to limit inflation. It is important to note that current inflationary pressures are the result of growing economic strength as opposed to economic turmoil. Although oil supply shocks could create a significant problem, spikes in food prices and in overall commodity prices should be manageable over the medium term, particularly if aggregate demand in the developed world remains muted, as we expect.

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.

RISKS OF INTERNATIONAL INVESTING

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.

Performance and Expenses

GROWTH OF $10,000 

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.

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 in 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 in 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 maintenance fee that is not included in the accompanying table. The account maintenance 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.

NOTES TO FINANCIAL STATEMENTS 

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), a diversified, open-end management investment company, is one portfolio established by the corporation. The fund commenced operations on November 30, 2000. The fund seeks to provide long-term capital growth, using the FTSE™ International Limited Developed ex North America Index.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

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.

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.

NOTE 2 - VALUATION

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 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. 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 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.

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.

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 1 – quoted prices in active markets for identical financial instruments

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)

Level 3 – unobservable inputs

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, 2011:

Following is a reconciliation of the fund’s Level 3 holdings for the six months ended April 30, 2011. 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, 2011, totaled $0 for the six months ended April 30, 2011.

NOTE 3 - DERIVATIVE INSTRUMENTS

During the six months ended April 30, 2011, 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, 2011, the fund held equity futures with cumulative unrealized gain of $348,000; 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, 2011, the fund recognized $55,000 of realized gain on Futures and a $238,000 change in unrealized gain 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, 2011, the fund’s exposure to futures, based on underlying notional amounts, was generally less than 1% 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.

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. Collateral is evaluated daily to ensure that its market value exceeds the delivery value of the repurchase agreements at maturity. 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. 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, 2011, the value of loaned securities was $33,312,000; and cash collateral investments totaled $35,017,000.

Other Purchases and sales of portfolio securities other than short-term securities aggregated $89,608,000 and $159,256,000, respectively, for the six months ended April 30, 2011.

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 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.

The fund intends to retain realized gains to the extent of available capital loss carryforwards. As of October 31, 2010, the fund had $41,196,000 of unused capital loss carryforwards, which expire: $357,000 in fiscal 2011, $11,710,000 in fiscal 2016, $18,272,000 in fiscal 2017 and $10,857,000 in fiscal 2018.

At April 30, 2011, the cost of investments for federal income tax purposes was $393,067,000. Net unrealized gain aggregated $55,576,000 at period-end, of which $97,415,000 related to appreciated investments and $41,839,000 related to depreciated investments.

NOTE 6 - FOREIGN TAXES

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, 2011, the fund had no deferred tax liability attributable to foreign securities and no foreign capital loss carryforwards.

NOTE 7 - 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). Price Associates has entered into a subadvisory agreement with T. Rowe Price International Ltd, a wholly owned subsidiary, 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 fund was previously managed by T. Rowe Price International, Inc. (Price International), which was merged into its parent company, Price Associates, effective at the close of business on December 31, 2010. Thereafter, Price Associates assumed responsibility for all of Price International’s existing investment management contracts, and Price International ceased all further operations. The corporate reorganization was designed to simplify Price Group’s corporate structure related to its international business and was intended to result in no material changes in the nature, quality, level, or cost of services provided to the T. Rowe Price funds.

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, 2011, 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.

Mutual funds and other accounts managed by T. Rowe Price and its affiliates (collectively, T. Rowe Price funds) may invest in the fund; however, no T. Rowe Price fund may invest for the purpose of exercising management or control over the fund. At April 30, 2011, 1% of the fund’s outstanding shares were held by T. Rowe Price funds.

APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT  

On March 9, 2011, the fund’s Board of Directors (Board) unanimously approved the continuation of the investment advisory contract (Contract) between the fund and its investment advisor, T. Rowe Price Associates, Inc. (Advisor), as well as the investment subadvisory contract (Subadvisory Contract) that the Advisor has entered into with T. Rowe Price International Ltd (Subadvisor). The Board considered a variety of factors in connection with its review of the 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
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, management of the fund’s portfolio and a variety of related activities, as well as financial and administrative services, reporting, and 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 noted that a restructuring involving the Advisor and certain of its affiliated investment advisors led to a restatement of the fund’s investment advisory contract and a new investment subadvisory contract, effective at the close of business on December 31, 2010. This restructuring, which resulted in T. Rowe Price Associates, Inc., becoming the fund’s new investment advisor and T. Rowe Price International Ltd becoming the fund’s new investment subadvisor, had been determined by the Board at a meeting in October 2010 not to diminish the nature, quality, or level of services provided to the fund or materially to change the manner in which advisory services were to be provided. 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 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 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 also received information on the estimated costs incurred and profits realized by the Advisor and its affiliates (including the Subadvisor) from advising T. Rowe Price mutual funds, as well as estimates of the gross profits realized from managing the fund in particular. 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 Contract from any economies of scale realized by the Advisor. The Board noted that, under the Contract, the fund pays the Advisor a single fee based on the fund’s assets and that the Advisor, in turn, pays all expenses of the fund, with certain exceptions. 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 Contract provided for a reasonable sharing of any benefits from economies of scale with the fund.

Fees
The Board reviewed the fund’s single-fee structure and compared it with fees and expenses of other comparable funds based on information and data supplied by Lipper. 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. (For these purposes, the Board assumed the fund’s management fee rate was equal to the single fee less the fund’s operating expenses.) The Board also reviewed the fee schedules for institutional accounts of the Advisor and its affiliates with similar mandates. Management provided the Board with information about the Advisor’s responsibilities and services provided to institutional account clients, which are more limited than its responsibilities for the fund and other T. Rowe Price mutual funds that it advises, and showing that the Advisor performs significant additional services and assumes greater risk for the fund and other T. Rowe Price mutual funds that it advises 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 Contract were reasonable.

Approval of the Contract
As noted, the Board approved the continuation of the 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 to approve the continuation of the Contract and the Subadvisory Contract (including the fees to be charged for services thereunder).
