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 36.4% 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 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:
Strategy [Heading] rr_StrategyHeading Investments, Risks, and Performance

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in emerging market companies. The fund may purchase the stocks of companies of any size. The fund expects to make substantially all of its investments in common stocks of companies located (or with primary operations) in emerging markets in Latin America, Asia, Europe, Africa, and the Middle East. The fund considers the following countries to be emerging markets (others may be added):
  • 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, 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.
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.
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.

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 efficient trading 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.
