T. Rowe Price Institutional International Funds, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The Institutional International Growth Equity Fund (the fund) is a diversified, open-end management investment company established by the corporation. The fund commenced operations on September 7, 1989. The fund seeks long-term growth of capital through investments primarily in the common stocks of established, non-U.S. companies.

Basis of Preparation
The fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 946 (ASC 946). The accompanying Portfolio of Investments was prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), including but not limited to ASC 946. GAAP requires the use of estimates made by management. Management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the Portfolio of Investments may differ from the values ultimately realized upon sale or maturity.

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.

The fund’s financial instruments are valued, and its net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business.

Fair Value
The fund’s financial instruments are reported at fair value, which GAAP defines as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The T. Rowe Price Valuation Committee (the Valuation Committee) has been established by the fund’s Board of Directors (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the fund’s Board; is chaired by the fund’s treasurer; and has representation from legal, portfolio management and trading, operations, and risk management.

Various valuation techniques and inputs are used to determine the fair value of financial instruments. GAAP establishes the following fair value hierarchy that categorizes the inputs used to measure fair value:

Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date

Level 2 – inputs other than Level 1 quoted prices that are observable, either directly or indirectly (including, but not limited to, quoted prices for similar financial instruments in active markets, quoted prices for identical or similar financial instruments in inactive markets, interest rates and yield curves, implied volatilities, and credit spreads)

Observable inputs are developed using market data, such as publicly available information about actual events or transactions, and reflect the assumptions that market participants would use to price the financial instrument. Unobservable inputs are those for which market data are not available and are developed using the best information available about the assumptions that market participants would use to price the financial instrument. GAAP requires valuation techniques to maximize the use of relevant observable inputs and minimize the use of unobservable inputs. When multiple inputs are used to derive fair value, the financial instrument is assigned to the level within the fair value hierarchy based on the lowest-level input that is significant to the fair value of the financial instrument. Input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level but rather the degree of judgment used in determining those values.

Valuation Techniques
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. OTC Bulletin Board securities are valued at the mean of the closing 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 closing bid and asked prices for domestic securities and the last quoted sale or closing price for international securities.

For valuation purposes, the last quoted prices of non-U.S. equity securities may be adjusted to reflect the fair value of such securities at the close of the NYSE. 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 quoted 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 quoted 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. The 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 quoted prices and information to evaluate or adjust those prices. The fund cannot predict how often it will use quoted 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 quoted prices, the next day’s opening prices in the same markets, and adjusted prices.

Actively traded domestic equity securities generally are categorized in Level 1 of the fair value hierarchy. Non-U.S. equity securities generally are categorized in Level 2 of the fair value hierarchy despite the availability of quoted prices because, as described above, the fund evaluates and determines whether those quoted prices reflect fair value at the close of the NYSE or require adjustment. OTC Bulletin Board securities, certain preferred securities, and equity securities traded in inactive markets generally are categorized in Level 2 of the fair value hierarchy.

Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation and are categorized in Level 1 of the fair value hierarchy. Forward currency exchange contracts are valued using the prevailing forward exchange rate and are categorized in Level 2 of the fair value hierarchy. Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value.

Thinly traded financial instruments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Valuation Committee. The objective of any fair value pricing determination is to arrive at a price that could reasonably be expected from a current sale. Financial instruments fair valued by the Valuation Committee are primarily private placements, restricted securities, warrants, rights, and other securities that are not publicly traded.

Subject to oversight by the Board, the Valuation Committee regularly makes good faith judgments to establish and adjust the fair valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of an equity investment with limited market activity, such as a private placement or a thinly traded public company stock, the Valuation Committee considers a variety of factors, which may include, but are not limited to, the issuer’s business prospects, its financial standing and performance, recent investment transactions in the issuer, new rounds of financing, negotiated transactions of significant size between other investors in the company, relevant market valuations of peer companies, strategic events affecting the company, market liquidity for the issuer, and general economic conditions and events. In consultation with the investment and pricing teams, the Valuation Committee will determine an appropriate valuation technique based on available information, which may include both observable and unobservable inputs. The Valuation Committee typically will afford greatest weight to actual prices in arm’s length transactions, to the extent they represent orderly transactions between market participants; transaction information can be reliably obtained; and prices are deemed representative of fair value. However, the Valuation Committee may also consider other valuation methods such as market-based valuation multiples; a discount or premium from market value of a similar, freely traded security of the same issuer; or some combination. Fair value determinations are reviewed on a regular basis and updated as information becomes available, including actual purchase and sale transactions of the issue. Because any fair value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions, and fair value prices determined by the Valuation Committee could differ from those of other market participants. Depending on the relative significance of unobservable inputs, including the valuation technique(s) used, fair valued securities may be categorized in Level 2 or 3 of the fair value hierarchy.

Valuation Inputs
The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on January 31, 2014:

Following is a reconciliation of the fund’s Level 3 holdings for the period ended January 31, 2014. Gain (loss) reflects both realized and change in unrealized gain/loss on Level 3 holdings during the period, if any. The change in unrealized gain/loss on Level 3 instruments held at January 31, 2014, totaled $8,000 for the period ended January 31, 2014.

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 credit exposure. The risks associated with the use of derivatives are different from, and potentially much greater than, the risks associated with investing directly in the instruments on which the derivatives are based. The fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover its settlement obligations under open derivative contracts. The fund values its derivatives at fair value, as described in Note 2.

Counterparty Risk and Collateral
The fund invests in derivatives, such as bilateral swaps, forward currency exchange contracts, or OTC options, that are transacted and settle directly with a counterparty (bilateral derivatives), and thereby expose the fund to counterparty risk. To mitigate this risk, the fund has entered into master netting arrangements (MNAs) with certain counterparties that permit net settlement under specified conditions and, for certain counterparties, also provide collateral agreements. MNAs may be in the form of International Swaps and Derivatives Association master agreements (ISDAs) or foreign exchange letter agreements (FX letters).

MNAs govern the ability to offset amounts the fund owes a counterparty against amounts the counterparty owes the fund (net settlement). Both ISDAs and FX letters generally allow net settlement in the event of contract termination and permit termination by either party prior to maturity upon the occurrence of certain stated events, such as failure to pay or bankruptcy. In addition, ISDAs specify other events, the occurrence of which would allow one of the parties to terminate. For example, a downgrade in credit rating of a counterparty would allow the fund to terminate while a decline in the fund’s net assets of more than a certain percentage would allow the counterparty to terminate. Upon termination, all bilateral derivatives with that counterparty would be liquidated and a net amount settled. ISDAs typically include collateral agreements whereas FX letters do not. Collateral requirements are determined based on the net aggregate unrealized gain or loss on all bilateral derivatives with each counterparty, subject to minimum transfer amounts that typically range from $100,000 to $250,000. Any additional collateral required due to changes in security values is transferred the next business day.

Collateral may be in the form of cash or debt securities issued by the U.S. government or related agencies; securities posted by the fund are so noted in the accompanying Portfolio of Investments. Collateral posted or received by the fund is held in a segregated account by the fund’s custodian. As of January 31, 2014, no collateral was pledged by either the fund or counterparties for bilateral derivatives.

Forward Currency Exchange Contracts
The fund uses forward currency exchange contracts (forwards) primarily to protect its non-U.S. dollar-denominated securities from adverse currency movements relative to the U.S. dollar. 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.

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks 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 through investments in T. Rowe Price institutional funds, in securities of companies located in emerging markets, issued by governments of emerging market countries, 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 impact the fund’s ability to buy or sell certain securities or repatriate proceeds to U.S. dollars.

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.

Securities Lending
The fund may lend its securities to approved brokers to earn additional income. Its securities lending activities are administered by a lending agent in accordance with a securities lending agreement. It receives collateral in the form of cash or 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; any additional collateral required due to changes in security values is delivered the next business day. Cash collateral is invested by the lending agent(s) in accordance with investment guidelines approved by fund management. Additionally, the lending agent indemnifies the fund against losses resulting from borrower default. Although risk is mitigated by the collateral and indemnification, 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, collateral investments decline in value, and the lending agent fails to perform. In accordance with GAAP, investments made with cash collateral are reflected in the accompanying Portfolio of Investments, but collateral received in the form of securities is not. At January 31, 2014, the value of loaned securities was $279,000; the value of cash collateral and related investments was $296,000.

When-Issued Securities
The fund may enter into when-issued purchase or sale commitments, pursuant to which it agrees to purchase or sell, respectively, an authorized but not yet issued security for a fixed unit price, with payment and delivery not due until issuance of the security on a scheduled future date. When-issued securities may be new securities or securities issued through a corporate action, such as a reorganization or restructuring. Until settlement, the fund maintains liquid assets sufficient to settle its commitment to purchase a when-issued security or, in the case of a sale commitment, the fund maintains an entitlement to the security to be sold.

At January 31, 2014, the cost of investments for federal income tax purposes was $81,560,000. Net unrealized gain aggregated $17,820,000 at period-end, of which $22,150,000 related to appreciated investments and $4,330,000 related to depreciated investments.

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

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 Equity Fund (the fund) is a diversified, open-end management investment company established by the corporation. The fund commenced operations on October 31, 2002.

Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date

Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation and are categorized in Level 1 of the fair value hierarchy. Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value.

Valuation Inputs
The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on January 31, 2014:

China A shares
The fund invests in certain Chinese equity securities (A shares) available only to local Chinese investors and Qualified Foreign Institutional Investors (QFII). The fund gains access to the A-share market through Price Associates, which serves as the registered QFII for all participating T. Rowe Price-sponsored products (each a participating account). Investment decisions related to A shares are specific to each participating account, and each account bears the resultant economic and tax consequences of its holdings and transactions in A shares. The fund is subject to certain restrictions and administrative processes relating to its ability to repatriate cash balances, investment proceeds, and earnings associated with its A shares and may incur substantial delays in gaining access to its assets or a loss of value in the event of noncompliance with applicable Chinese rules or requirements.

At January 31, 2014, the cost of investments for federal income tax purposes was $835,128,000. Net unrealized gain aggregated $119,063,000 at period-end, of which $190,051,000 related to appreciated investments and $70,988,000 related to depreciated investments.

Valuation Inputs
The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on January 31, 2014:

Participation Notes
The fund may invest in participation notes and other types of equity-linked complex instruments (collectively, participation notes), through which a counterparty provides exposure to common stock, in the form of an unsecured interest, in markets where direct investment by the fund is not possible. Participation notes provide the economic benefit of common stock ownership to the fund, while legal ownership and voting rights are retained by the counterparty. Although participation notes are usually structured with a defined maturity or termination date, early redemption may be possible. Risks associated with participation notes include the possible failure of a counterparty to perform in accordance with the terms of the agreement, inability to transfer or liquidate the notes, potential delays or an inability to redeem before maturity under certain market conditions, and limited legal recourse against the issuer of the underlying common stock.

At January 31, 2014, the cost of investments for federal income tax purposes was $143,787,000. Net unrealized gain aggregated $49,075,000 at period-end, of which $53,190,000 related to appreciated investments and $4,115,000 related to depreciated investments.
