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. 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 Emerging Markets Equity Fund | T. Rowe Price Institutional Emerging Markets Equity Fund | USD ($)	112	350	606	1,340

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 20.9% of the average value of its portfolio.

Investments, Risks, and Performance Principal Investment Strategies

The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in emerging market companies. For purposes of determining whether the fund invests at least 80% of its net assets in emerging market companies, the fund relies on MSCI Inc. to determine which countries are considered emerging markets and relies on the country assigned to a security by MSCI Inc. or another unaffiliated data provider. The fund considers frontier markets to be a subset of emerging markets and any investments in frontier markets will be counted toward the fund’s 80% investment policy. The fund expects to primarily invest in common stocks of companies located (or with primary operations) in emerging markets in Latin America, Asia, Europe, Africa, and the Middle East. The countries in which the fund normally invests include, but are not limited to, the following:

• Asia: China, India, Indonesia, Malaysia, Pakistan, Philippines, South Korea, Sri Lanka, Taiwan, Thailand, and Vietnam.

• Latin America: Argentina, Belize, Brazil, Chile, Colombia, Mexico, Panama, Peru, and Venezuela.

• Europe: Croatia, Czech Republic, Estonia, Greece, Hungary, Kazakhstan, Latvia, Lithuania, Poland, Romania, Russia, Slovakia, Slovenia, Turkey, and Ukraine.

• Africa and the Middle East: Bahrain, Botswana, Egypt, Jordan, Kenya, Kuwait, Lebanon, Mauritius, Morocco, Nigeria, Oman, Qatar, Saudi Arabia, South Africa, Tunisia, United Arab Emirates, and Zimbabwe.

The fund may purchase the stocks of companies of any size. 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 at times invest significantly in China.

Security selection reflects a growth style. The adviser relies on a global team of investment analysts dedicated to in-depth fundamental research in an effort to identify companies capable of achieving and sustaining above-average, long-term earnings growth. The adviser seeks to purchase stocks of companies at reasonable prices in relation to present or anticipated earnings, cash flow, or book value.

In selecting investments, the adviser generally favors companies with one or more of the following characteristics:

• leading or improving market position;

• attractive business niche;

• attractive or improving franchise or industry position;

• seasoned management;

• stable or improving earnings and/or cash flow; and

• sound or improving balance sheet.

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 fund, there is no guarantee that the fund will achieve its objective(s). 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, which may be even greater during periods of market disruption or volatility, are summarized as follows.

Emerging markets Investments in emerging market countries are subject to greater risk and overall volatility than investments in the U.S. and developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. In addition to the risks associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on the fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates.

International investing Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. Non-U.S. 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, investments outside the U.S. are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets.

Investing in China The Chinese government has historically exercised significant control over China’s economy and its financial markets through, among other things, its monetary policies and allocation of resources, management of currency exchange rates, preferential treatment or restrictions relating to industries deemed sensitive to national interests, and limitations on foreign ownership of Chinese securities. Although economic reforms have liberalized trade policy and reduced government control, changes in these policies or increased government intervention could adversely impact affected industries or companies. China’s currency, which historically has been managed in a tight range relative to the U.S. dollar, may in the future be subject to greater uncertainty as Chinese authorities change the policies that determine the official currency exchange rate. Additionally, the Chinese economy is highly dependent on the exportation of products and services, and could experience a significant slowdown due to a reduction in global demand for Chinese exports, contraction in spending on domestic goods by Chinese consumers, trade or political disputes with China’s major trading partners, natural disasters, or public health threats. The U.S. and China have been imposing tariffs on certain goods traded between the countries. Heightened trade tensions between the U.S. and China, and the institution of additional tariffs or trade barriers between China and any of its key trading partners, including the U.S., could have a significant adverse impact on the Chinese economy.

Investing in Asia Many Asian economies have at various times been negatively affected by inflation, currency devaluations, an over-reliance on international trade and exports, political and social instability, and less developed financial systems and securities trading markets. Trade restrictions, unexpected decreases in exports, changes in government policies, or natural disasters could have a significant impact on companies doing business in Asia. The Asian region may be significantly affected by political unrest, military conflict, economic sanctions, and less demand for Asian products and services.

Sector exposure At times, the fund may have a significant portion of its assets invested in securities of issuers conducting business in a broadly related group of industries within the same economic sector. Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly. Investments in the financials sector are susceptible to adverse developments relating to regulatory changes, interest rate movements, the availability of capital and cost to borrow, and the rate of debt defaults.

Frontier markets Frontier markets generally have smaller economies and less mature capital markets than emerging markets. As a result, the risks associated with investing in emerging market countries are magnified in frontier market countries. Frontier markets are more susceptible to abrupt changes in currency values, have less mature markets and settlement practices, and can have lower trading volumes that could lead to greater price volatility and illiquidity. Investor protections in frontier market countries may be limited and settlement procedures and custody services may prove inadequate in certain markets.

Liquidity A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit the fund’s ability to purchase or sell holdings in a timely manner at a desired price. An inability to sell a portfolio holding can adversely affect the fund’s overall value or prevent the fund from being able to take advantage of other investment opportunities. Liquidity risk may be magnified during periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund’s ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. Large redemptions may also have a negative impact on the fund’s overall liquidity.

Growth investing The fund’s growth approach to investing could cause it to underperform other stock funds that employ a different investment style. Growth stocks tend to be more volatile than certain other types of stocks and their prices may fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market.

Stock investing 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 stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry.

Active management The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

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 following bar chart illustrates how much returns can differ from year to year by showing calendar year returns and the best and worst calendar quarter returns during those years for the fund.

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, if applicable.

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.
