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. The example also assumes that your investment has a 5% return each year, the fund's operating expenses remain the same, and the expense limitation currently in place is not renewed. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - (USD $)	1 year	3 years	5 years	10 years
T. Rowe Price Institutional International Growth Equity Fund	77	266	527	1,273

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 fund 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 52.0% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund expects to invest substantially all of its assets in stocks outside the U.S. and to diversify broadly among developed and emerging countries throughout the world. The fund may purchase the stocks of companies of any size, but its focus will typically be on large-sized companies and, to a lesser extent, medium-sized companies. Normally, at least 80% of the fund's net assets (including any borrowings for investment purposes) will be invested in stocks.

While the fund invests with an awareness of the global economic backdrop and the outlook for industry sectors and individual countries, bottom-up stock selection is the focus of our decision-making. Country allocation is driven largely by stock selection, though we may limit investments in markets that appear to have poor overall prospects.

Security selection reflects a growth style. The fund 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. We seek to purchase stocks of such companies at reasonable prices in relation to present or anticipated earnings, cash flow, or book value.

In selecting investments, the fund 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 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 riskThe fund is subject to the risk that the investment adviser's judgments about the attractiveness, value, or potential appreciation of the fund's investments may prove to be incorrect. If the securities selected and strategies employed by the fund fail to produce the intended results, the fund could underperform other funds with similar objectives and investment strategies.

Risks of 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 prices 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 company or a particular industry.

Foreign investing risk Investing in the securities of non-U.S. companies involves special risks not typically associated with investing in U.S. companies. Foreign securities tend to be more volatile and less liquid than investments in U.S. securities, and may lose value because of adverse political, social or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, foreign 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.

Investment style risk Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. 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 usually 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.

Performance

The bar chart showing calendar year returns and the average annual total returns table indicate risk by illustrating how much returns can differ from one year to the next and how fund performance compares with that of a comparable market index. The fund's past performance (before and after taxes) is not necessarily an indication of future performance.

The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

Worst Quarter	12/31/08	-26.44%

In addition, the average annual total returns table shows hypothetical after-tax returns to suggest 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 individual retirement account.
