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. No portfolio turnover rate is disclosed because the Fund had not yet commenced operations prior to the date of this prospectus.

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 Narrative [Text Block]

The Fund generally invests in equity securities of small-capitalization domestic and foreign issuers, including securities of issuers in developing or emerging market countries (i.e., those that are in the initial stages of their industrial cycle). Equity securities are common and preferred stocks, convertible securities, rights and warrants to purchase common stock and depositary receipts.

     The Fund uses the following criteria to determine whether an issuer is a small-capitalization issuer: if it has a market capitalization, at the time of purchase, no larger than the largest capitalized issuer included in the MSCI AC World Small Cap Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. As of October 31, 2011, the capitalization of companies in the MSCI AC World Small Cap Index ranged from $5.2 million to $7.4 billion. The companies within the MSCI AC World Small Cap Index are considered representative of small-sized companies.

     The Fund may invest up to 10% of its net assets in fixed-income securities such as investment-grade debt securities and longer-term U.S. Government securities.

     The Fund is non-diversified, which means it can invest a greater percentage of its assets in any one issuer than a diversified fund can.

     In selecting securities, the portfolio managers seek to identify issuers that are both attractively priced relative to their prospective earnings and cash flow, and have strong long-term growth prospects. In evaluating issuers, the portfolio managers emphasize several factors such as the quality of the issuer’s management team, their commitment to securing a competitive advantage, and the issuer’s sustainable growth potential.

     The portfolio managers typically consider whether to sell a security in any of four circumstances: 1) a more attractive investment opportunity is identified, 2) the full value of the investment is deemed to have been realized, 3) there has been a fundamental negative change in the management strategy of the issuer, or 4) there has been a fundamental negative change in the competitive environment.

     The Fund may at times invest a significant amount of its assets in cash and cash equivalents if the portfolio managers are not able to find equity securities that meet their investment criteria. As a result, the Fund may not achieve its investment objective.

Risk [Heading]

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:

Currency/Exchange Rate Risk. The dollar value of the Fund’s foreign investments will be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded.

Debt Securities Risk. The Fund may invest in debt securities that are affected by changing interest rates and changes in their effective maturities and credit quality.

Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging 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.

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.

Non-Diversification Risk. The Fund is non-diversified and can invest a greater portion of its assets in a single issuer. A change in the value of the issuer could affect the value of the Fund more than if it was a diversified fund.

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.

U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default.
