Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 15.9% of the average value of its portfolio.

Expense Example [Heading] rr_ExpenseExampleHeading Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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:
Strategy [Heading] rr_StrategyHeading Investments, Risks, and Performance

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The fund expects to invest substantially all of its assets outside the U.S. and to diversify broadly among developed and, to a lesser extent, emerging countries throughout the world. The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in non-U.S. stocks and at least 65% of its net assets in stocks of large-cap companies.

The fund takes a core approach to investing, which provides some exposure to both growth and value styles of investing. The fund relies on a global research team to search for particularly promising stocks throughout developed and, to a lesser extent, emerging markets. Securities will be selected that in our view have the most favorable combination of company fundamentals and valuation.

In selecting investments, the fund generally favors companies with one or more of the following characteristics:
  • attractive business niche with potential for earnings growth;
  • attractive valuation relative to the company’s peers or its own historical norm;
  • barriers to entry in its business;
  • seasoned management;
  • healthy balance sheet; and
  • potential to grow dividends or conduct share repurchases.
The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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 risk The 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.

International investing risk Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. companies. International 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, international investments are subject to settlement practices, and regulatory and financial reporting standards, that differ from those of the U.S.

Investment style risk Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. Because the fund holds stocks with both growth and value characteristics, it could underperform other stock funds that take a strictly growth or value approach to investing when one style is currently in favor. Growth stocks tend to be more volatile than the overall stock market and can have sharp price declines as a result of earnings disappointments. Value stocks carry the risk that the market will not recognize their intrinsic value or that they are actually appropriately priced at a low level.
Risk Lose Money [Text] rr_RiskLoseMoney The fund’s share price fluctuates, which means you could lose money by investing in the fund.

[1] T. Rowe Price Associates, Inc. has agreed (through February 28, 2015) to waive its fees and/or bear any expenses (excluding interest, expenses related to borrowings, taxes and brokerage, extraordinary expenses, and acquired fund fees) that would cause the fund's ratio of expenses to average daily net assets to exceed 0.75%.

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 after the waiver or payment, or if it would result in the expense ratio exceeding 0.75% (excluding interest, expenses related to borrowings, taxes and brokerage, extraordinary expenses, and acquired fund fees).
