Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table.

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that an expense limitation arrangement currently in place is not renewed; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	1 year	3 years	5 years	10 years
T. Rowe Price Institutional International Concentrated Equity Fund | T. Rowe Price Institutional International Concentrated Equity Fund | USD ($)	77	239	413	920

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 147.0% of the average value of its portfolio.

Investments, Risks, and Performance<br/><br/>Principal Investment Strategies

The fund expects to primarily invest in stocks of companies located outside the U.S. Under normal conditions, the fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in stocks of non-U.S. companies and no more than 15% of its net assets will be invested in stocks of companies in emerging markets. For purposes of determining whether the fund invests at least 80% of its net assets in non-U.S. stocks, the fund relies on the country assigned to a security by MSCI Inc. or another unaffiliated data provider. Because the fund focuses on developed markets outside the U.S., it typically has significant exposure to companies in Europe.

The fund is “nondiversified,” meaning it may invest a greater portion of its assets in a single company and own more of the company’s voting securities than is permissible for a “diversified” fund.

While the adviser invests with an awareness of the global economic backdrop and the adviser’s outlook for certain industries, sectors, and individual countries, the adviser’s decision-making process focuses on bottom-up stock selection. Country allocation is driven largely by stock selection, though the adviser may limit investments in markets or industries that appear to have poor overall prospects.

The fund may purchase the stocks of companies of any size, but typically focuses on larger companies, and does not emphasize either a growth or value bias in selecting investments. The adviser generally selects securities for the fund that the adviser believes have the most favorable combination of company fundamentals, earnings potential, and relative valuation.

The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

Principal Risks

As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund are summarized as follows:

Active management risks The investment adviser’s judgments about the attractiveness, value, or potential appreciation of the fund’s investments may prove to be incorrect. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies if the fund’s overall investment selections or strategies fail to produce the intended results.

Risks of stock investing Common stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of a stock in which the fund invests may decline due to general weakness in the stock market or because of factors that affect a particular company or industry.

International investing risks Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. International securities tend to be more volatile and have lower overall liquidity than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, international investments are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. These risks are heightened for the fund’s investments in emerging markets, which are more susceptible to governmental interference, less efficient trading markets, and the imposition of local taxes and restrictions on gaining access to the fund’s investments.

Geographic concentration risks To the extent the fund concentrates its investments in a particular geographic region, the fund’s performance is closely tied to the social, political, and economic conditions within that region. Political developments and changes in regulatory, tax, or economic policy in particular countries within the region could significantly affect the markets in those countries as well as the entire region. As a result, the fund is likely to be more volatile than more geographically diverse international funds.

The European financial markets have been experiencing increased volatility due to concerns over rising government debt levels of several European countries, and these events may continue to significantly affect all of Europe. European economies could be significantly affected by, among other things, rising unemployment, the imposition or unexpected elimination of fiscal and monetary controls by member countries of the European Economic and Monetary Union, uncertainty surrounding the euro, the success of governmental actions to reduce budget deficits, and a disorderly exit by the United Kingdom from the European Union.

Nondiversification risks As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a comparable diversified fund.

Market capitalization risks The fund’s focus on large companies subjects the fund to the risks that larger companies may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and that they may be less capable of responding quickly to competitive challenges and industry changes. Because the fund may invest in companies of any size, its share price could be more volatile than a fund that invests only in large companies. Small and medium-sized companies typically have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund’s performance information represents only past performance (before and after taxes) and is not necessarily an indication of future results.

The performance for the periods shown reflects the performance of the fund while it was named the T. Rowe Price Institutional International Concentrated Equity Fund. Effective March 1, 2019, the T.

The following table shows the average annual total returns for the fund, and also compares the returns with the returns of a relevant broad-based market index, as well as with the returns of one or more comparative indexes that have investment characteristics similar to those of the fund.

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA.

[1] Effective April 1, 2019, the fund will no longer assess a redemption fee on any redemption from the fund (or exchange out of the fund), regardless of how long the shares were held.

[1] T. Rowe Price Associates, Inc., has agreed (through February 28, 2021) to waive its fees and/or bear any expenses (excluding interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses) that would cause the fund’s ratio of expenses to average daily net assets to exceed 0.75%. The agreement may be terminated at any time beyond February 28, 2021, with approval by the fund’s Board of Directors. Fees waived and expenses paid under this agreement (and a previous limitation of 0.75%) are subject to reimbursement to T. Rowe Price Associates, Inc., by the fund whenever the fund’s expense ratio is below 0.75%. However, no reimbursement will be made more than three years from the date such amounts were initially waived or reimbursed. The fund may only make repayments to T. Rowe Price Associates, Inc., if such repayment does not cause the fund’s expense ratio (after the repayment is taken into account) to exceed the lesser of: (1) the expense limitation in place at the time such amounts were waived; or (2) the fund’s current expense limitation.

[1] Effective July 1, 2018, the MSCI EAFE Index Net replaced the MSCI EAFE Index as the fund’s primary benchmark. The new index assumes the reinvestment of dividends after the deduction of withholding taxes applicable to the country where the dividend is paid; as such, the returns of the new benchmark are more representative of the returns experienced by investors in foreign issuers.
