Example. The following 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 a class of shares of the Fund for the time periods indicated. 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 expenses would be as follows:

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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 the 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% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Principal Investment Strategies. The Fund mainly invests in the common stock of growth companies that are domiciled or have their primary operations outside of the United States. It may invest 100% of its assets in securities of foreign companies. The Fund may invest in emerging markets as well as in developed markets throughout the world. From time to time it may place greater emphasis on investing in one or more particular regions such as Asia, Europe or Latin America. Under normal market conditions the Fund will:

invest at least 65% of its total assets in common and preferred stocks of issuers in at least three different countries outside of the United States, and
emphasize investments in common stocks of issuers that the portfolio managers consider to be "growth" companies.

The Fund does not limit its investments to issuers within a specific market capitalization range and at times may invest a substantial portion of its assets in one or more particular capitalization ranges. The Fund can also buy securities convertible into common stock and other securities having equity features. The Fund can use hedging and certain derivative instruments to seek capital appreciation or to try to manage investment risks.

In selecting investments for the Fund's portfolio, the portfolio managers evaluate investment opportunities on a company-by-company basis. The portfolio managers look primarily for foreign companies with high growth potential using a "bottom up" investment approach, that is, by looking at the investment performance of individual stocks before considering the impact of general or industry-specific economic trends. This approach includes fundamental analysis of a company's financial statements and management structure and consideration of the company's operations, product development, and industry position.

The portfolio managers currently focus on the following factors, which may vary in particular cases and may change over time:

companies that enjoy a strong competitive position and high demand for their products or services;
companies with accelerating earnings growth and cash flow; and
diversity among companies, industries and countries to help reduce the risks of foreign investing, such as currency fluctuations and stock market volatility.

The portfolio managers also consider the effect of worldwide trends on the growth of particular business sectors and looks for companies that may benefit from those trends. The trends currently considered include: mass affluence, new technologies, restructuring and aging. The portfolio managers do not invest any fixed amount of the Fund's assets according to these criteria and the trends that are considered may change over time. The portfolio managers monitor individual issuers for changes in the factors above, which may trigger a decision to sell a security, but does not require a decision to do so.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or because of poor investment selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

Main Risks of Investing in Stock. The value of the Fund's portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company's stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company's sector or industry, or changes in government regulations affecting the company or its industry.

At times, the Fund may emphasize investments in a particular industry or economic or market sector. To the extent that the Fund increases its emphasis on investments in a particular industry or sector, the value of its investments may fluctuate more in response to events affecting that industry or sector, such as changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others.

Main Risks of Foreign Investing. Foreign securities are subject to special risks. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company's operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company's assets, or other political and economic factors. These risks may be greater for investments in developing or emerging market countries.

Special Risks of Developing and Emerging Markets. The economies of developing or emerging market countries may be more dependent on relatively few industries that may be highly vulnerable to local and global changes. The governments of developing and emerging market countries may also be more unstable than the governments of more developed countries. These countries generally have less developed securities markets or exchanges, and less developed legal and accounting systems. Securities may be more difficult to sell at an acceptable price and may be more volatile than securities in countries with more mature markets. The value of developing or emerging market currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company's assets, restrictions on foreign ownership of local companies and restrictions on withdrawing assets from the country. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Time-Zone Arbitrage. The Fund may invest in securities of foreign issuers that are traded in U.S. or foreign markets. If the Fund invests a significant amount of its assets in foreign markets, it may be exposed to "time-zone arbitrage" attempts by investors seeking to take advantage of differences in the values of foreign securities that might result from events that occur after the close of the foreign securities market on which a security is traded and before the Fund's net asset value is calculated. If such time-zone arbitrage were successful, it might dilute the interests of other shareholders. The Fund's use of "fair value pricing" to adjust certain market prices of foreign securities may help deter those activities.

Main Risks of Growth Investing. If a growth company's earnings or stock price fails to increase as anticipated, or if its business plans do not produce the expected results, its securities may decline sharply. Growth companies may be newer or smaller companies that may experience greater stock price fluctuations and risks of loss than larger, more established companies. Newer growth companies tend to retain a large part of their earnings for research, development or investments in capital assets. Therefore, they may not pay any dividends for some time. Growth investing has gone in and out of favor during past market cycles and is likely to continue to do so. During periods when growth investing is out of favor or when markets are unstable, it may be more difficult to sell growth company securities at an acceptable price. Growth stocks may also be more volatile than other securities because of investor speculation.

Who Is The Fund Designed For? The Fund is designed primarily for investors seeking capital appreciation over the long term. Those investors should be willing to assume the greater risks of share price fluctuations that are typical for an aggressive fund focusing on growth stock investments, and the special risks of investing in both developed and emerging foreign countries. The Fund does not seek current income and is not designed for investors needing income. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing in the Fund.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
