NOTES TO PORTFOLIO OF INVESTMENTS

T. Rowe Price Institutional International Funds, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The Institutional Emerging Markets Bond Fund (the fund), a nondiversified, open-end management investment company, is one portfolio established by the corporation. The fund seeks to provide high income and capital appreciation.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Basis of Preparation
The accompanying Portfolio of Investments was prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), which require the use of estimates made by fund management. Fund management believes that estimates and security valuations are appropriate; however, actual results may differ from those estimates, and the security valuations reflected in the Portfolio of Investments may differ from the values ultimately realized upon sale of the securities.

Investment Transactions
Investment transactions are accounted for on the trade date.

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 are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction.

New Accounting Pronouncement
On January 1, 2010, the fund adopted new accounting guidance that requires enhanced disclosures about fair value measurements in the financial statements. Adoption of this guidance had no impact on the fund’s net assets or results of operations.

NOTE 2 - VALUATION

The fund’s investments are reported at fair value as defined under GAAP. The fund values its investments 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
Debt securities are generally 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 acquisitiongenerally 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. Forward currency exchange contracts are valued using the prevailing forward exchange rate. Swaps are valued at prices furnished by independent swap dealers or by an independent pricing service.

Other investments, including restricted securities, 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 T. Rowe Price Valuation Committee, established by the fund’s Board of Directors.

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

Level 1 – quoted prices in active markets for identical securities

Level 2 – observable inputs other than Level 1 quoted prices (including, but not limited to, quoted prices for similar securities, 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 investments at that level. The following table summarizes the fund’s investments, based on the inputs used to determine their values on March 31, 2010:

NOTE 3 - DERIVATIVE INSTRUMENTS

The fund may invest 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 andcredit 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.

Forward Currency Exchange Contracts
The fund uses forward currency exchange contracts (forwards) primarily to protect its non-U.S. dollar-denominated holdings from adverse currency movements and to gain exposure to currencies for the purposes of risk management or enhanced return. A forward involves an obligation to purchase or sell a fixed amount of a specific currency on a future date at a price set at the time of the contract. Although certain forwards may be settled by exchanging only the net gain or loss on the contract, most forwards are settled with the exchange of the underlying currencies in accordance with the specified terms. Forwards are valued at the unrealized gain or loss on the contract, which reflects the net amount the fund either is entitled to receive or obligated to deliver, as measured by the difference between the forward exchange rates at the date of entry into the contract and the forward rates at the reporting date. Risks related to the use of forwards include the possible failure of counterparties to meet the terms of the agreements; that anticipated currency movements will not occur thereby reducing the fund’s total return; and the potential for losses in excess of the fund’s initial investment.

Credit Default Swaps
The fund may use swaps in an effort to manage exposure to changes in interest rates and credit quality, to adjust overall exposure to certain markets, to enhance total return or protect the value of portfolio securities, to serve as a cash management tool, and/or to adjust portfolio duration or credit exposure. Credit default swaps are agreements where one party (the protection buyer) agrees to make periodic payments to another party (the protection seller) in exchange for protection against specified credit events, such as certain defaults and bankruptcies related to an underlying credit instrument, index, or issuer thereof. Upon occurrence of a specified credit event, the protection seller is required to pay the buyer the difference between the notional amount of the swap and the value of the underlying credit, either in the form of a net cash settlement or by paying the gross notional amount and accepting delivery of the relevant underlying credit. Generally, the payment risk for the seller of protection is inversely related to the current market price of the underlying credit; therefore, the payment risk increases as the price of the relevant underlying credit declines due to market valuations of credit quality. The notional amount of protection sold by the fund reflects the maximum potential amount the fund could be required to pay under such contracts. The value of a swap included in net assets is the unrealized gain or loss on the contract. Risks related to the use of credit default swaps include the possible inability of the fund to accurately assess the current and future creditworthiness of underlying issuers, the possible failure of a counterparty to perform in accordance with the terms of the swap agreements, potential government regulation that could adversely affect the fund’s swap investments, and potential losses in excess of the fund’s initial investment.

Counterparty Risk and Collateral
The fund has entered into collateral agreements with certain counterparties to mitigate counterparty risk associated with over-the-counter (OTC) derivatives, including swaps and forward currency exchange contracts. Subject to certain minimum exposure requirements (which range from $100,000 to $500,000), collateral generally is determined based on the net aggregate unrealized gain or loss on all OTC derivative contracts with a particular counterparty. Collateral, both pledged by and for the benefit of the fund, is held in a segregated account by a third-party agent and can be in the form of cash or debt securities issued by the U.S. government or related agencies. Securities posted as collateral by the fund are so noted in the accompanying Portfolio of Investments and remain in the fund’s net assets. As of March 31, 2010, no collateral was pledged by either the fund or counterparties.

The fund’s maximum risk of loss from counterparty credit risk on OTC derivatives is the aggregate unrealized gain on appreciated contracts in excess of any collateral pledged by the counterparty for the benefit of the fund. In accordance with standard derivatives agreements, counterparties to OTC derivatives may be able to terminate derivative contracts prior to maturity in the event the fund fails to maintain sufficient asset coverage; its net assets decline by stated percentages; or it otherwise fails to meet the terms of its agreements, which would cause the fund to accelerate payment of any net liability owed to the counterparty under the contract.

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.

Emerging Markets
The fund may invest, directly or indirectly, in securities of companies located in emerging markets, issued by governments of emerging market countries,and/or denominated in or linked to the currencies of emerging market countries. Emerging market securities are often subject to greater price volatility, less liquidity, and higher rates of inflation than U.S. securities. In addition, emerging markets may be subject to greater political, economic and social uncertainty, and differing regulatory environments that may potentially impacting the fund’s ability to buy or sell certain securities or repatriate proceeds to U.S. dollars.

Noninvestment-Grade Debt Securities
The fund may invest, either directly or through its investments in T. Rowe Price institutional funds, in noninvestment-grade debt securities, commonly referred to as “high-yield” or “junk” bonds. The noninvestment-grade bond market may experience sudden and sharp price swings due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high-profile default, or a change in the market’s psychology. These events may decrease the ability of issuers to make principal and interest payments and adversely affect the liquidity or value, or both, of such securities.

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.

NOTE 5 - FEDERAL INCOME TAXES

At March 31, 2010, the cost of investments for federal income tax purposes was $153,184,000. Net unrealized gain aggregated $17,185,000 at period-end, of which $17,997,000 related to appreciated investments and $812,000 related to depreciated investments.

NOTE 6 - RELATED PARTY TRANSACTIONS

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 T. Rowe Price Associates, Inc. (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.

Risks related to the use of forwards include the possible failure of counterparties to meet the terms of the agreements; that anticipated currency movements will not occur thereby reducing the fund’s total return; and the potential for losses in excess of the fund’s initial investment.

Futures Contracts
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; and/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. 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. Variation margin is recorded as unrealized gain or loss until the contracts are closed. For a futures contract, the value 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, interest rates, and/orcurrency values, and potential losses in excess of the fund’s initial investment.

Credit Default Swaps
The fund may use swaps in an effort to manage exposure to changes in interest rates and credit quality, to adjust overall exposure to certain markets, to enhance total return or protect the value of portfolio securities, to serve as a cash management tool, and/or to adjust portfolio duration or credit exposure. Credit default swaps are agreements where one party (the protection buyer) agrees to make periodic payments to another party (the protection seller) in exchange for protection against specified credit events, such as certain defaults and bankruptcies related to an underlying credit instrument, index, or issuer thereof. Upon occurrence of a specified credit event, the protection seller is required to pay the buyer the difference between the notional amount of the swap and the value of the underlying credit, either in the form of a net cash settlement or by paying the gross notional amount and accepting delivery of the relevant underlying credit. The value of a swap included in net assets is the unrealized gain or loss on the contract. Risks related to the use of credit default swaps include the possible inability of the fund to accurately assess the current and future creditworthiness of underlying issuers, the possible failure of a counterparty to perform in accordance with the terms of the swap agreements, potential government regulation that could adversely affect the fund’s swap investments, and potential losses in excess of the fund’s initial investment.

Counterparty Risk and Collateral
The fund has entered into collateral agreements with certain counterparties to mitigate counterparty risk associated with over-the-counter (OTC) derivatives, including swaps and forward currency exchange contracts. Subject to certain minimum exposure requirements (which range from $100,000 to $500,000), collateral generally is determined based on the net aggregate unrealized gain or loss on all OTC derivative contracts with a particular counterparty. Collateral, both pledged by and for the benefit of the fund, is held in a segregated account by a third-party agent and can be in the form of cash or debt securities issued by the U.S. government or related agencies. Securities posted as collateral by the fund are so noted in the accompanying Portfolio of Investments and remain in the fund’s net assets. As of March 31, 2010, no collateral was pledged by either the fund or counterparties.

The fund’s maximum risk of loss from counterparty credit risk on OTC derivatives is the aggregate unrealized gain on appreciated contracts in excess of any collateral pledged by the counterparty for the benefit of the fund. Counterparty risk related to exchange-traded futures and options contracts is minimal because the exchange’s clearinghouse provides protection against defaults. In accordance with standard derivatives agreements, counterparties to OTC derivatives may be able to terminate derivative contracts prior to maturity in the event the fund fails to maintain sufficient asset coverage; its net assets decline by stated percentages; or it otherwise fails to meet the terms of its agreements, which would cause the fund to accelerate payment of any net liability owed to the counterparty under the contract. For exchange-traded derivatives such as futures and options, each broker in its sole discretion may change margin requirements applicable to the fund.

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.

Emerging market securities are often subject to greater price volatility, less liquidity, and higher rates of inflation than U.S. securities.

NOTE 5 - FEDERAL INCOME TAXES

At March 31, 2010, the cost of investments for federal income tax purposes was $192,819,000. Net unrealized loss aggregated $384,000 at period-end, of which $4,304,000 related to appreciated investments and $4,688,000 related to depreciated investments.

NOTE 6 - RELATED PARTY TRANSACTIONS

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 T. Rowe Price Associates, Inc. (Price Associates) and considered affiliates of the fund. The T.
