Manager’s Letter
T. Rowe Price Institutional International Core Equity Fund

Dear Investor

Stocks in international developed markets posted strong overall gains in the six and 12 months ended October 31, 2017. European markets found support in a more stable political environment, improved economic growth, and stronger corporate earnings. Japanese equities advanced as the country’s economy sustained modest growth rates and corporations continued to shift toward more shareholder-friendly practices. Emerging markets rose as the global economy improved and protectionist rhetoric in the U.S. receded.

As shown in the Performance Comparison table, the Institutional International Core Equity Fund returned 13.04% and 27.35% for the 6- and 12-month periods ended October 31, 2017, respectively. The portfolio significantly outperformed the MSCI EAFE Index and its Lipper peer group average for the 6- and 12-month reporting periods.

Sector performance was uniformly positive in absolute terms for the 12-month period. Our information technology stocks led the way with exceptional gains, followed by materials and financials. Consumer discretionary and consumer staples performed roughly in line with the MSCI EAFE Index, while telecommunication services, utilities, and real estate trailed with smaller gains. Stock selection was particularly beneficial to performance versus our benchmark, while sector weightings were also helpful.

Market Environment

European stocks gained 27% for the 12-month reporting period amid positive developments on the political, economic, and corporate fronts. Early fears about the disruptive political impact of rising populism proved largely unfounded, and the environment stabilized as centrists won key elections in the Netherlands, France, and Germany. Europe’s economic recovery continued to grind forward, supported by increasing business investment, stronger loan growth, declining unemployment, and stronger global trade. Monetary policy remains broadly accommodative, although the European Central Bank (ECB) acknowledged recent economic improvements and removed its bias toward easy policy in June. European corporate earnings continued to reflect the solid economic and political backdrop and registered the best growth in three years.

Japanese equities advanced approximately 18% in U.S. dollar terms for the reporting period. Japan’s economy is showing gradual improvement, recently recording a sixth consecutive quarter of modest growth, and improvements in the global economy offer further support to Japan’s important export sector. Prime Minister Shinzo Abe has made corporate governance reform one of his primary objectives, and Japanese companies are increasing cash payouts to shareholders through dividends and share repurchases. Importantly, they have also reduced their cross-shareholdings, a practice in which Japanese corporations own shares in major clients and industry partners. Corporate profits in Japan recently reached all-time highs, and earnings growth, though starting from a lower base, recently met or exceeded many of its developed market peers.

Emerging markets stocks rose 26% in U.S. dollar terms for the reporting period, benefiting from continued growth in the global economy, relatively stable prices for energy and raw materials, and reduced concerns about protectionism and interest rate policies in key developed markets. Asian markets were among the biggest gainers, with China and India climbing 41% and 23%, respectively.

Most major currencies appreciated versus the U.S. dollar for the 12-month period. The euro and the UK pound gained 6.2% and 8.7% against the dollar, respectively, while the Japanese yen lost 7.5%.

Portfolio Highlights and Positioning

Our information technology stocks gained approximately 50% in absolute terms for the 12-month reporting period. Stock selection and an overweight allocation contributed to outperformance versus the MSCI EAFE Index. This is an area of the market where disruptive change can provide compelling investment opportunities in companies using game-changing technologies and processes to disrupt traditional industries and gain market share. Samsung Electronics (South Korea) was among our biggest contributors, benefiting from a vigorous demand cycle and improved profitability across its business lines, particularly in its memory and mobile phone areas. We are also encouraged by management’s moves toward improving shareholder value through share repurchases and dividends. Electronics and semiconductor companies Tokyo Electron (Japan) and Broadcom (Singapore) were also strong performers. Kakaku.com (Japan), which offers Web-based price comparisons and reviews for restaurants, hotels, and other retail outlets, declined amid a slowdown in growth. We established positions in Chinese social networking platform YY and Renesas Electronics (Japan), which makes semiconductors, microcontrollers, and integrated circuits. (Please refer to the fund’s portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)

Our materials stocks posted the portfolio’s second-largest absolute gains as prices stabilized for certain commodities. Positive security selection led to outperformance versus the MSCI benchmark, but an underweight allocation detracted modestly. We maintained an underweight position due to our ongoing concerns about a long-term supply/demand imbalance across much of the global commodities complex. Stora Enso (Finland) was a strong positive contributor. The company should continue to benefit as management shifts its focus from traditional lower-growth, lower-margin paper businesses toward higher-growth, higher-margin cardboard and packaging products. Japanese chemical company Asahi Kasei climbed amid strong end-market demand and a good pricing environment. Pure-play copper producer Antofagasta (Chile) and BASF (Germany), the world’s largest chemical producer, were also solid contributors. We established positions in Independence Group (Australia), a low-cost nickel miner that should benefit from increased demand for electric car batteries, and Amcor (Australia), the world’s largest packaging company.

The portfolio’s financials stocks advanced 33% in absolute terms while security selection and an overweight sector position boosted results versus the MSCI benchmark. Valuations in the sector have increased but remain favorable compared with other areas of the market, and we expect further tailwinds from higher interest rates in the U.S. and, when they come to pass, in Europe. European banks benefited from gradual improvements in European and global economic growth and received an indirect boost from rising U.S. interest rates. BNP Paribas (France), DNB (Norway), ING Groep (Netherlands), and Intesa Sanpaolo (Italy) were among the portfolio’s top contributors. Our insurance holdings also performed well, led by globally diversified composite insurer AXA (France) and life insurer Storebrand (Norway), which benefited from an increased focus on fee-based offerings versus traditional guaranteed products. We eliminated Swedish bank Swedbank and German insurer Allianz after good runs. We established positions in Erste Group Bank (Austria), a key player in growing Central and Eastern European markets, and Element Fleet Management (Canada), which facilitates financing and manages vehicle fleets for large commercial clients.

Our health care stocks climbed 17% in absolute terms, but the sector, as a whole, underperformed the broader international equities market amid concerns about regulatory pressures in the critical U.S. market. Stock selection benefited results versus the benchmark, while an overweight detracted modestly. On the plus side, global pharmaceutical giant Bayer (Germany) was a strong contributor. The company saw good results for a number of drugs, including Xarelto, a leading blood thinner with patent protection expected to last for several more years. Bayer’s pending acquisition of U.S.-based Monsanto should benefit its world-class crop science business. Pharmaceutical firm Sanofi (France) and medical equipment manufacturer Koninklijke Philips (Netherlands) were also strong performers. Astellas Pharma (Japan) declined due to disappointing results for its prostate cancer drug Xtandi, which was challenged by price cuts. Biotechnology holding Shire (UK) declined amid concerns about competitive pressures and pricing power.

From a geographic perspective, the portfolio maintains its focus on Europe. Our UK allocation stood at approximately 17% at the end of the period. Despite ongoing uncertainty surrounding the Brexit process, we continue to find high-quality companies in the UK with shareholder-friendly management operating in a business-friendly environment. Japan accounts for approximately 21% of the portfolio, and we continue to find company-specific opportunities despite the country’s challenging demographics and modest economic growth. Emerging markets account for approximately 6% of the portfolio, with China as our largest exposure.

Investment Outlook

Europe’s economic fundamentals continue to improve at a gradual pace, and the ECB’s monetary policy remains broadly supportive despite recent indications that it may begin reining in some stimulus measures. After years of disappointment, corporate earnings have improved and should continue to grow moderately over the coming quarters. Brexit negotiations and Italy’s troubled financial sector are continuing concerns, but centrist victories over populist and nationalist candidates in 2017’s elections could provide a more stable political backdrop to address these challenges. As Angela Merkel’s recent struggles to form a governing coalition in Germany suggest, however, political unity in Europe remains somewhat of a moving target, at least for the time being.

In Japan, several years of loose monetary policy and attempts at structural reform have produced mixed results. Aggressive monetary stimulus has successfully driven up prices for some imported goods, and economic growth has been modestly positive for several quarters. We are encouraged that incentives for Japanese companies to focus on profitability and shareholder returns appear to be gaining some traction among corporate management. Our overall position is tempered, however, by long-standing concerns about challenging demographics, stubbornly low inflation and wage growth, and the government’s ability to execute remaining structural reforms.

We believe selectivity is essential in emerging markets in light of mixed valuations and disparate fundamentals and governance practices. Although China faces a number of long-term risks related to its political system, outstanding debt, and other factors, its leaders have several policy options available to manage the risks and maintain economic growth. We continue to look for growth opportunities in China, focusing on innovative companies growing from the ground up and creating entirely new products and categories.

Overall, valuations for international stocks are richer than they were in the recent past, as the market has priced in the improved investor sentiment. While it has become harder for us to find attractively valued investment ideas, we will continue to rely on our global research platform to identify companies that are able to grow earnings and cash flow through superior business models and disciplined capital allocation.

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
T. Rowe Price Institutional International Core Equity Fund

Growth of $1 Million

This chart shows the value of a hypothetical $1 million investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The result is compared with benchmarks, which may include a broad-based market index and a peer group average or index. Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.

Fund Expense Example

As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period.

Actual Expenses
The first line of the following table (Actual) provides information about actual account values and actual expenses. You may use the information on this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes
The information on the second line of the table (Hypothetical) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

Notes to Financial Statements
T. Rowe Price Institutional International Core Equity Fund
October 31, 2017

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

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

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

Investment Transactions, Investment Income, and Distributions Investment transactions are accounted for on the trade date basis. Income and expenses are recorded on the accrual basis. Realized gains and losses are reported on the identified cost basis. 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, are recorded as income tax expense. Income distributions are declared and paid annually. Distributions to shareholders are recorded on the ex-dividend date. A capital gain distribution may also be 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 respective date of such transaction. The portion of the results of operations attributable to changes in foreign exchange rates on investments is not bifurcated from the portion attributable to changes in market prices. 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.

New Accounting Guidance In March 2017, the FASB issued amended guidance to shorten the amortization period for certain callable debt securities, held at a premium. The guidance is effective for fiscal years and interim periods beginning after December 15, 2018. Adoption will have no effect on the fund’s net assets or results of operations.

On August 1, 2017, the fund implemented amendments to Regulation S-X, issued by the Securities and Exchange Commission, which require standardized, enhanced disclosures, particularly related to derivatives, in investment company financial statements. Adoption had no effect on the fund’s net assets or results of operations.

Indemnification In the normal course of business, the fund may provide indemnification in connection with its officers and directors, service providers, and/or private company investments. The fund’s maximum exposure under these arrangements is unknown; however, the risk of material loss is currently considered to be remote.

NOTE 2 - VALUATION

The fund’s financial instruments are valued and its net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business. However, the NAV per share may be calculated at a time other than the normal close of the NYSE if trading on the NYSE is restricted, if the NYSE closes earlier, or as may be permitted by the SEC.

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) is an internal committee that has been delegated certain responsibilities by the fund’s Board of Directors (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the Board and has representation from legal, portfolio management and trading, operations, risk management, and the fund’s treasurer.

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

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

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

Level 3 – unobservable inputs

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

Valuation Techniques 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 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 equity securities listed on a domestic exchange 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. 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 October 31, 2017:

There were no material transfers between Levels 1 and 2 during the year ended October 31, 2017.

NOTE 3 - 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.

Securities Lending The fund may lend its securities to approved borrowers to earn additional income. Its securities lending activities are administered by a lending agent in accordance with a securities lending agreement. Security loans generally do not have stated maturity dates, and the fund may recall a security at any time. The fund 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 to the fund the next business day. Cash collateral is invested 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. Securities lending revenue consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower, compensation to the lending agent, and other administrative costs. In accordance with GAAP, investments made with cash collateral are reflected in the accompanying financial statements, but collateral received in the form of securities is not. At October 31, 2017, the value of loaned securities was $1,669,000; the value of cash collateral and related investments was $1,751,000.

Other Purchases and sales of portfolio securities other than short-term securities aggregated $36,967,000 and $17,498,000, respectively, for the year ended October 31, 2017.

NOTE 4 - FEDERAL INCOME TAXES

No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its taxable income and gains. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character but are not adjusted for temporary differences.

The fund files U.S. federal, state, and local tax returns as required. The fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

Distributions during the years ended October 31, 2017 and October 31, 2016, totaled $3,185,000 and $3,349,000, respectively, and were characterized as ordinary income for tax purposes. At October 31, 2017, the tax-basis cost of investments, including derivatives, and components of net assets were as follows:

The difference between book-basis and tax-basis net unrealized appreciation (depreciation) is attributable to the deferral of losses from wash sales for tax purposes. The fund intends to retain realized gains to the extent of available capital loss carryforwards. Because the fund is required to use capital loss carryforwards that do not expire before those with expiration dates, all or a portion of its capital loss carryforwards subject to expiration could ultimately go unused. During the year ended October 31, 2017, the fund utilized $68,000 of capital loss carryforwards. The fund’s available capital loss carryforwards as of October 31, 2017, expire as follows: $134,000 in fiscal 2019; $14,747,000 have no expiration.

NOTE 5 - FOREIGN TAXES

The fund is subject to foreign income taxes imposed by certain countries in which it invests. Additionally, certain foreign currency transactions are subject to tax, and capital gains realized 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 capital gains is reflected as a component of realized or change in unrealized gain/loss on securities in the accompanying financial statements. At October 31, 2017, the fund had no deferred tax liability attributable to foreign securities and no foreign capital loss carryforwards.

NOTE 6 - RELATED PARTY TRANSACTIONS

The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). Price Associates has entered into a sub-advisory agreement(s) with one or more of its wholly owned subsidiaries, to provide investment advisory services to the fund. The investment management agreement between the fund and Price Associates provides for an annual investment management fee equal to 0.65% of the fund’s average daily net assets. The fee is computed daily and paid monthly.

The fund is also subject to a contractual expense limitation through February 28, 2019. During the limitation period, Price Associates is required to waive its management fee and pay the fund for any expenses (excluding interest, expenses related to borrowings, taxes, brokerage, and other non-recurring expenses permitted by the investment management agreement) that would otherwise cause the fund’s ratio of annualized total expenses to average net assets (expense ratio) to exceed its expense limitation of 0.75%. The fund is required to repay Price Associates for expenses previously waived/paid to the extent its net assets grow or expenses decline sufficiently to allow repayment without causing the fund’s expense ratio (after the repayment is taken into account) to exceed both: (1) the expense limitation in place at the time such amounts were waived; and (2) the class’s current expense limitation. However, no repayment will be made more than three years after the date of a payment or waiver. Pursuant to this agreement, $127,000 of expenses were waived/paid by Price Associates during the year ended October 31, 2017. Including this amount, expenses previously waived/paid by Price Associates in the amount of $442,000 remain subject to repayment by the fund at October 31, 2017.

In addition, the fund has entered into service agreements with Price Associates and a wholly owned subsidiary of Price Associates (collectively, Price). Price Associates provides certain accounting and administrative services to the fund. T. Rowe Price Services, Inc. provides shareholder and administrative services in its capacity as the fund’s transfer and dividend-disbursing agent. For the year ended October 31, 2017, expenses incurred pursuant to these service agreements were $86,000 for Price Associates and less than $1,000 for T. Rowe Price Services, Inc. The total amount payable at period-end pursuant to these service agreements is reflected as Due to Affiliates in the accompanying financial statements.

The fund may invest in certain open-end management investment companies managed by Price Associates and considered affiliates of the fund: the T. Rowe Price Government Reserve Fund or the T. Rowe Price Treasury Reserve Fund, organized as money market funds, or the T. Rowe Price Short-Term Fund, a short-term bond fund (collectively, the Price Reserve Funds). The Price Reserve 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 Funds pay no investment management fees.

The fund may participate in securities purchase and sale transactions with other funds or accounts advised by Price Associates (cross trades), in accordance with procedures adopted by the fund’s Board and Securities and Exchange Commission rules, which require, among other things, that such purchase and sale cross trades be effected at the independent current market price of the security. During the year ended October 31, 2017, the fund had no purchases or sales cross trades with other funds or accounts advised by Price Associates.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of T. Rowe Price Institutional International Funds, Inc. and
Shareholders of T. Rowe Price Institutional International Core Equity Fund

In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the T. Rowe Price Institutional International Core Equity Fund (one of the portfolios comprising T. Rowe Price Institutional International Funds, Inc., hereafter referred to as the “Fund”) as of October 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of October 31, 2017 by correspondence with the custodian, brokers, and transfer agent, provide a reasonable basis for our opinion.

A copy of this code of ethics is filed as an exhibit to this Form N-CSR. No substantive amendments were approved or waivers were granted to this code of ethics during the period covered by this report.

Item 3. Audit Committee Financial Expert.

The registrant’s Board of Directors/Trustees has determined that Mr. Bruce W. Duncan qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. Duncan is considered independent for purposes of Item 3 of Form N-CSR.

Item 4. Principal Accountant Fees and Services.

(a) – (d) Aggregate fees billed for the last two fiscal years for professional services rendered to, or on behalf of, the registrant by the registrant’s principal accountant were as follows:

Audit fees include amounts related to the audit of the registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements and specifically include the issuance of a report on internal controls and, if applicable, agreed-upon procedures related to fund acquisitions. Tax fees include amounts related to services for tax compliance, tax planning, and tax advice. The nature of these services specifically includes the review of distribution calculations and the preparation of Federal, state, and excise tax returns. All other fees include the registrant’s pro-rata share of amounts for agreed-upon procedures in conjunction with service contract approvals by the registrant’s Board of Directors/Trustees.

(e)(1) The registrant’s audit committee has adopted a policy whereby audit and non-audit services performed by the registrant’s principal accountant for the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant require pre-approval in advance at regularly scheduled audit committee meetings. If such a service is required between regularly scheduled audit committee meetings, pre-approval may be authorized by one audit committee member with ratification at the next scheduled audit committee meeting. Waiver of pre-approval for audit or non-audit services requiring fees of a de minimis amount is not permitted.

(2) No services included in (b) – (d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees.

(g) The aggregate fees billed for the most recent fiscal year and the preceding fiscal year by the registrant’s principal accountant for non-audit services rendered to the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant were $1,432,000 and $1,890,000, respectively.

(h) All non-audit services rendered in (g) above were pre-approved by the registrant’s audit committee. Accordingly, these services were considered by the registrant’s audit committee in maintaining the principal accountant’s independence.

EX-99.CODE ETH

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND SENIOR FINANCIAL
OFFICERS OF THE PRICE FUNDS
UNDER THE SARBANES-OXLEY ACT OF 2002

I. General Statement. This Code of Ethics (the “Price Funds S-O Code”) has been designed to bring the Price Funds into compliance with the applicable requirements of the Sarbanes-Oxley Act of 2002 (the “Act”) rules promulgated by The Securities and Exchange Commission thereunder (“Regulations”). The Price Funds S-O Code applies solely to the Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller of, or persons performing similar functions for, a Price Fund (whether such persons are employed by a Price Fund or third party) (“Covered Officers”). The “Price Funds” shall include each mutual fund that is managed, sponsored and distributed by affiliates of T. Rowe Price Group, Inc. (“Group”). The investment managers to the Price Funds will be referred to as the “Price Fund Advisers.” A list of Covered Officers is attached as Exhibit A.

The Price Fund Advisers have, along with their parent, T. Rowe Price Group, Inc. (“Group”) also maintained a comprehensive Code of Ethics and Conduct (the “Group Code”) since 1972, which applies to all officers, directors and employees of the Price Funds, Group and its affiliates.

As mandated by the Act, Group has adopted a Code (the “Group S-O Code”), similar to the Price Funds S-O Code, which applies solely to its principal executive and senior financial officers. The Group S-O Code and the Price Funds S-O Code will be referred to collectively as the “S-O Codes”.

The Price Funds S-O Code has been adopted by the Price Funds in accordance with the Act and Regulations thereunder and will be administered in conformity with the disclosure requirements of Item 2 of Form N-CSR. The S-O Codes are attachments to the Group Code. In many respects the S-O Codes are supplementary to the Group Code, but the Group Code is administered separately from the S-O Codes, as the S-O Codes are from each other.

II. Purpose of the Price Funds S-O Code. The purpose of the Price Funds S-O Code, as mandated by the Act and the Regulations, is to establish standards that are reasonably designed to deter wrongdoing and to promote:

Ethical Conduct. Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships.

Disclosure. Full, fair, accurate, timely and understandable disclosure in reports and documents that the Price Funds file with, or submit to, the SEC and in other public communications made by the Price Funds.

Compliance. Compliance with applicable governmental laws, rules and regulations.

Reporting of Violations. The prompt internal reporting of violations of the Price Funds S-O Code to an appropriate person or persons identified in the Price Funds S-O Code.

Accountability. Accountability for adherence to the Price Funds S-O Code.

III. Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest.

Overview. Each Covered Officer owes a duty to the Price Funds to adhere to a high standard of honesty and business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the interests of, or his or her service to, the Price Funds. For example, a conflict of interest would arise if a Covered Officer, or a member of his or her family, receives improper personal benefits as a result of his or her position with a Price Fund.

Certain conflicts of interest covered by the Price Funds S-O Code arise out of the relationships between Covered Officers and the Price Funds and may already be subject to provisions regulating conflicts of interest in the Investment Company Act of 1940 (“Investment Company Act”), the Investment Advisers Act of 1940 (“Investment Advisers Act”) and the Group Code. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with a Price Fund because of their status as “affiliated persons” of a Price Fund. The compliance programs and procedures of the Price Funds and Price Fund Advisers are designed to prevent, or identify and correct, violations of these provisions.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between a Price Fund and its Price Fund Adviser (and its affiliates) of which the Covered Officers may also be officers or employees. As a result, the Price Funds S-O Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Price Funds or for the Price Fund Advisers, or for both), be involved in establishing policies and implementing decisions which will have different effects on these entities. The participation of the Covered Officers in such activities is inherent in the contractual relationship between each Price Fund and its respective Price Fund Adviser. Such participation is also consistent with the performance by the Covered Officers of their duties as officers of the Price Funds and, if consistent with the provisions of the Investment Company Act and the Investment Advisers Act, it will be deemed to have been handled ethically.

Other conflicts of interest are covered by the Price Funds S-O Code, even if these conflicts of interest are not addressed by or subject to provisions in the Investment Company Act and the Investment Advisers Act.

Whenever a Covered Officer is confronted with a conflict of interest situation where he or she is uncertain as to the appropriate action to be taken, he or she should discuss the matter with the Chairperson of Group’s Ethics Committee or another member of the Committee.

Handling of Specific Types of Conflicts. Each Covered Officer (and close family members) must not:

Entertainment. Accept entertainment from any company with which any Price Fund or any Price Fund Adviser has current or prospective business dealings, including portfolio companies, unless such entertainment is in full compliance with the policy on entertainment as set forth in the Group Code.

Gifts. Accept any gifts, except as permitted by the Group Code.

Improper Personal Influence. Use his or her personal influence or personal relationships improperly to influence investment decisions, brokerage allocations or financial reporting by the Price Funds to the detriment of any one or more of the Price Funds.

Taking Action at the Expense of a Price Fund. Cause a Price Fund to take action, or fail to take action, for the personal benefit of the Covered Officer rather than for the benefit of one or more of the Price Funds.

Misuse of Price Funds’ Transaction Information. Use knowledge of portfolio transactions made or contemplated for a Price Fund or any other clients of the Price Fund Advisers to trade personally or cause others to trade in order to take advantage of or avoid the market impact of such portfolio transactions.

Outside Business Activities. Engage in any outside business activity that detracts from a Covered Officer’s ability to devote appropriate time and attention to his or her responsibilities to a Price Fund.

Service Providers. Excluding Group and its affiliates, have any ownership interest in, or any consulting or employment relationship with, any of the Price Funds’ service providers, except that an ownership interest in public companies is permitted

Receipt of Payments. Have a direct or indirect financial interest in commissions, transaction charges, spreads or other payments paid by a Price Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest (such as compensation or equity ownership) arising from the Covered Officer’s employment by Group or any of its affiliates.

Service as a Director or Trustee. Serve as a director, trustee or officer of any public or private company or a non-profit organization that issues securities eligible for purchase by any of the Price Funds, unless approval is obtained as required by the Group Code.

IV. Covered Officers’ Specific Obligations and Accountabilities.

A. Disclosure Requirements and Controls. Each Covered Officer must familiarize himself or herself with the disclosure requirements (Form N-1A registration statement, proxy (Schedule 14A), shareholder reports, Forms N-SAR, N-CSR, etc.) applicable to the Price Funds and the disclosure controls and procedures of the Price Fund and the Price Fund Advisers.

B. Compliance with Applicable Law. It is the responsibility of each Covered Officer to promote compliance with all laws, rules and regulations applicable to the Price Funds and the Price Fund Advisers. Each Covered Officer should, to the extent appropriate within his or her area of responsibility, consult with other officers and employees of the Price Funds and the Price Fund Advisers and take other appropriate steps with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Price Funds file with, or submit to, the SEC, and in other public communications made by the Price Funds.

C. Fair Disclosure. Each Covered Officer must not knowingly misrepresent, or cause others to misrepresent, facts about a Price Fund to others, whether within or outside the Price organization, including to the Price Fund’s directors and auditors, and to governmental regulators and self-regulatory organizations.

D. Initial and Annual Affirmations. Each Covered Officer must:

1. Upon adoption of the Price Funds S-O Code (or thereafter, as applicable, upon becoming a Covered Officer), affirm in writing that he or she has received, read, and understands the Price Funds S-O Code.

2. Annually affirm that he or she has complied with the requirements of the Price Funds S-O Code.

E. Reporting of Material Violations of the Price Funds S-O Code. If a Covered Officer becomes aware of any material violation of the Price Funds S-O Code or laws and governmental rules and regulations applicable to the operations of the Price Funds, he or she must promptly report the violation (“Report”) to the Chief Legal Counsel of the Price Funds (“CLC”). Failure to report a material violation will be considered itself a violation of the Price Funds S-O Code. The CLC is identified in the attached Exhibit B.

It is the Price Funds policy that no retaliation or other adverse action will be taken against any Covered Officer or other employee of a Price Fund, a Price Fund Adviser or their affiliates based upon any lawful actions of the Covered Officer or employee with respect to a Report made in good faith.

F. Annual Disclosures. Each Covered Officer must report, at least annually, all affiliations or other relationships as called for in the “Annual Questionnaire for Executive Officers and/or Employee Directors/Trustees of Group and the Price Funds.”

V. Administration of the Price Funds S-O Code. The Ethics Committee is responsible for administering the Price Funds S-O Code and applying its provisions to specific situations in which questions are presented.

A. Waivers and Interpretations. The Chairperson of the Ethics Committee has the authority to interpret the Price Funds S-O Code in any particular situation and to grant waivers where justified, subject to the approval of the Joint Audit Committee of the Price Funds. All material interpretations concerning Covered Officers will be reported to the Joint Audit Committee of the Price Funds at its next meeting. Waivers, including implicit waivers, to Covered Officers will be publicly disclosed as required in the Instructions to N-CSR. Pursuant to the definition in the Regulations, an implicit waiver means a Price Fund’s failure to take action within a reasonable period of time regarding a material departure from a provision of the Price Funds S-O Code that has been made known to an “executive officer” (as defined in Rule 3b-7 under the Securities Exchange Act of 1934) of a Price Fund. An executive officer of a Price Fund includes its president and any vice-president in charge of a principal business unit, division or function.

B. Violations/Investigations. The following procedures will be followed in investigating and enforcing the Price Funds S-O Code:

1. The CLC will take or cause to be taken appropriate action to investigate any potential or actual violation reported to him or her.

2. The CLC, after consultation if deemed appropriate with Outside Counsel to the Price Funds, will make a recommendation to the appropriate Price Funds Board regarding the action to be taken with regard to each material violation. Such action could include any of the following: a letter of censure or suspension, a fine, a suspension of trading privileges or termination of officership or employment. In addition, the violator may be required to surrender any profit realized (or loss avoided) from any activity that is in violation of the Price Funds S-O Code.

VI. Amendments to the Price Funds S-O Code. Except as to the contents of Exhibit A and Exhibit B, the Price Funds S-O Code may not be materially amended except in written form, which is specifically approved or ratified by a majority vote of each Price Fund Board, including a majority of the independent directors on each Board.

VII. Confidentiality. All reports and records prepared or maintained pursuant to the Price Funds S-O Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law, the Price Funds S-O Code or as necessary in connection with regulations under the Price Funds S-O Code, such matters shall not be disclosed to anyone other than the directors of the appropriate Price Fund Board, Outside Counsel to the Price Funds, members of the Ethics Committee and the CLC and authorized persons on his or her staff.
