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 21% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests primarily in equity securities and depositary receipts of foreign issuers. The principal types of equity securities in which the Fund invests are common and preferred stock.        The Fund invests, under normal circumstances, in securities of issuers located in at least three different countries outside of the U.S. The Fund may also invest up to 1.25 times the amount of the exposure to emerging markets countries in the MSCI ACWI ex USA Growth Index. Emerging markets countries are those countries that are in the initial stages of their industrial cycles.        The Fund invests primarily in securities of issuers that are considered by the Fund's portfolio managers to have potential for earnings or revenue growth.        The Fund invests primarily in the securities of large-capitalization issuers; however, the Fund may invest a significant amount of its net assets in the securities of mid-capitalization issuers.        The Fund can invest in derivative instruments, including forward foreign currency contracts and futures contracts.        The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.        The Fund can use futures contracts to gain exposure to the broad market in connection with managing cash balances or to hedge against downside risk.        The portfolio managers employ a disciplined investment strategy that emphasizes fundamental research to identify quality growth companies and is supported by quantitative analysis, portfolio construction and risk management techniques. Investments for the portfolio are selected bottom-up on a security-by-security basis. The focus is on the strengths of individual issuers, rather than sector or country trends. The portfolio managers' strategy primarily focuses on identifying issuers that they believe have sustainable above-average earnings growth, efficient capital allocation, and attractive prices.        The Fund's portfolio managers may consider selling a security for several reasons, including when (1) its price changes such that they believe it has become too expensive, (2) the original investment thesis for the company is no longer valid, or (3) a more compelling investment opportunity is identified.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:        Depositary Receipts Risk. Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts or to pass through to them any voting rights with respect to the deposited securities.        Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.        Developing/Emerging Markets Securities Risk. The prices of securities issued by foreign companies and governments located in developing/emerging markets countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.        Foreign Securities Risk. The Fund's foreign investments may be affected by changes in a foreign country's exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.        Geographic Focus Risk. From time to time the Fund may invest a substantial amount of its assets in securities of issuers located in a single country or a limited number of countries. If the Fund focuses its investments in this manner, it assumes the risk that economic, political and social conditions in those countries will have a significant impact on its investment performance. The Fund's investment performance may also be more volatile if it focuses its investments in certain countries, especially emerging markets countries.        Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile.        Investing in the European Union Risk. Many countries in the European Union are susceptible to high economic risks associated with high levels of debt, notably due to investments in sovereign debts of European countries such as Greece, Italy and Spain. One or more member states might exit the European Union, placing its currency and banking system in jeopardy. The European Union faces major issues involving its membership, structure, procedures and policies, including the adoption, abandonment or adjustment of the new constitutional treaty, the European Union's enlargement to the south and east, and resolution of the European Union's problematic fiscal and democratic accountability. Efforts of the member states to further unify their economic and monetary policies may increase the potential for the downward movement of one member state's market to cause a similar effect on other member states' markets. European countries that are part of the European Economic and Monetary Union may be significantly affected by the tight fiscal and monetary controls that the union seeks to impose on its members.        Management Risk. The investment techniques and risk analysis used by the Fund's portfolio managers may not produce the desired results.        Market Risk. The prices of and the income generated by the Fund's securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.        Small- and Mid-Capitalization Risks. Stocks of small- and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small- and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.
