Summary 1

Investment Objective

The fund seeks long-term growth of capital through investments primarily in the common stocks of companies located (or with primary operations) in emerging markets.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

Fees and Expenses of the Fund

Shareholder fees (fees paid directly from your investment)
Redemption fee (as a percentage of amount redeemed on shares held for 90 days or less)	2.00%
Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees	1.10%
Other expenses	0.00%
Total annual fund operating expenses	1.10%

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 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:

1 year	3 years	5 years	10 years
$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 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 21.1% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in emerging market companies. The fund expects to make substantially all of its investments in common stocks of companies located (or with primary operations) in emerging markets (which include frontier markets) in Latin America, Asia, Europe, Africa, and the

T. Rowe Price 2

Middle East. The fund considers frontier markets to be a subset of emerging markets and any investments in frontier markets will be counted towards the fund’s 80% policy. The fund relies on MSCI, Inc. to determine which countries are considered emerging markets, and the fund expects to primarily invest in the countries listed below (other countries may be added or listed countries may be removed):

·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.

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. 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 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:

Summary 3

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 investments selected and strategies employed by the fund fail to produce the intended results, the fund could underperform in comparison to 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 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 risk 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 less liquid 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.

Emerging markets risk The risks of international investing are heightened for securities of issuers in emerging market countries. 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 all of the risks of investing in international developed markets, emerging markets are more susceptible to governmental interference, local taxes being imposed on international investments, restrictions on gaining access to sales proceeds, and less liquid and less efficient trading markets.

Frontier markets, considered by the fund to be a subset of emerging markets, generally have smaller economies and less mature capital markets than emerging markets. As a result, the risks of investing in emerging market countries are magnified in frontier market countries. Frontier markets are more susceptible to abrupt changes in currency values, less mature markets and settlement practices, and lower trading volumes that could lead to greater price volatility and illiquidity.

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 when compared to 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.

Market capitalization risk 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 often have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies. Larger companies may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and they may be less capable of responding quickly to competitive challenges and industry changes.

Performance The bar chart showing calendar year returns and the average annual total returns table provide some indications of the risks of investing in the fund by showing how much returns can differ from year to year and how the fund’s average annual returns for certain periods compare with the returns of a relevant broad-based market index, as well as with the returns of other comparative indexes that have investment characteristics similar to those of 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 fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

In addition, the average annual total returns 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-

Summary 5

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. In some cases, the figure shown for “returns after taxes on distributions and sale of fund shares” may be higher than the figure shown for “returns before taxes” because the calculations assume the investor received a tax deduction for any loss incurred on the sale of shares.
