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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 73% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading What are the Fund’s main investment strategies?
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund primarily invests in the securities of companies in the Asia Pacific region.

Under normal circumstances, the Fund will invest at least 80% of its Assets in securities of foreign companies located throughout the Asia Pacific region, except Japan. “Asia Pacific region” includes, among others, Australia, China, Hong Kong, India, Indonesia, South Korea, Malaysia, New Zealand, Pakistan, Philippines, Singapore, Taiwan, Thailand and Vietnam. “Assets” means net assets, plus the amount of borrowings for investment purposes. A company “located in the Asia Pacific region” is any company: that is organized under the laws of, or has a principal office in a country in the Asia Pacific region (other than Japan); the principal securities market for which is in the Asia Pacific region (other than Japan); that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in the Asia Pacific region (other than Japan); or at least 50% of the assets of which are located in the Asia Pacific region (other than Japan). The Fund may invest a substantial part of its assets in just one country. For purposes of the policy above, the Fund may invest in securities of foreign companies by purchasing participatory or participation notes.

The Fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark at the time of investment, the Fund may invest up to 35% of its total assets in that industry.

The securities purchased by the Fund may include, but are not limited to, common stocks, preferred stock, convertible securities, depositary receipts, real estate investment trusts, warrants and rights, trust or partnership interests, and other instruments that have similar economic characteristics to equity securities, such as participatory or participation notes.

The Fund may utilize exchange-traded futures for the efficient management of cash flows.

The Fund will invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to invest in companies the sub-adviser believes are undervalued and/or have strong momentum. In identifying securities that have strong momentum, the sub-adviser looks for securities which have prices that have been increasing and that the sub-adviser believes will continue to increase.

The Fund may invest in securities denominated in U.S. dollars, other major reserve currencies, such as the euro, yen and pound sterling, and currencies of other countries in which it can invest. The sub-adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. It may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

The Fund will sell securities if the sub-adviser believes the issuer of such securities no longer meets certain growth and value criteria, if certain political and economic events occur or if it believes that more attractive opportunities are available.
Risk [Heading] rr_RiskHeading The Fund’s Main Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met. The Sub-Adviser has great flexibility in selecting investments because the Fund is unconstrained by capitalization, sector and style. This increased flexibility may present greater investment risk than a fund with more rigid investment restrictions because the success of the Sub-Adviser’s portfolio selections is dependent upon a greater number of variables.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.


Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less-established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers.

Asia Pacific Market Risk. The small size of securities markets and the low trading volume in some countries in the Asia Pacific region may lead to a lack of liquidity. The share prices of companies in the region tend to be volatile and there is a significant possibility of loss. Many of the countries in the region are developing, both politically and economically, and as a result companies in the region may be subject to risks like nationalization or other forms of government interference, and/or may be heavily reliant on only a few industries or commodities. Investments in the region may also be subject to currency risks, such as restrictions on the flow of money in and out of the country, extreme volatility relative to the U.S. dollar, and devaluation, all of which could decrease the value of the Fund.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Asian Pacific securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

China Region Risk. In additional to the risks listed under “Foreign Securities and Emerging Markets Risks” and “Asia Pacific Market Risks,” investments in China, Hong Kong and Taiwan are subject to legal, regulatory, monetary and economic risks. Investments involve political and legal uncertainties, currency fluctuations and currency controls, the risk of confiscatory taxation, and nationalization or expropriation of assets. The Chinese securities markets are emerging markets characterized by greater price volatility. China is dominated by the one-party rule of the Communist Party, and the Chinese government exercises significant control over China’s economic growth. Though Taiwan is not dominated by one-party rule and employs a free market economy, Taiwan’s political and economic relationship with China, particularly the continuing disagreement as to Taiwan’s sovereignty, could adversely impact investments in Taiwan.

At times, there may be a high correlation among the Chinese and Taiwanese markets. Accordingly, because the Fund may invest a significant portion of its assets in these markets, it is subject to greater risks of adverse events that occur in those markets and may experience greater volatility than a fund that is more broadly diversified geographically.

Industry Concentration Risk. The Fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark at the time of investment, the Fund may invest up to 35% of its total assets in that industry. Concentrating Fund investments in companies conducting business in the same industry will subject the Fund to a greater risk of loss as a result of adverse economic, business, political, regulatory or other developments affecting that industry than if its investments were not so concentrated.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty.

Volcker Rule Risk. As of the commencement of the Fund’s operations, the adviser and/or its affiliates owned 25% or more of the Fund’s outstanding ownership interests. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder known as the Volcker Rule, if the adviser and/or its affiliates own 25% or more of the outstanding ownership interests of the Fund after one year from the implementation of the Fund’s investment strategy (or such longer period as may be permitted by the Federal Reserve), the Fund could be subject to restrictions on trading that would adversely impact the Fund’s ability to execute its investment strategy. As a result, the adviser and/or its affiliates may be required to reduce their ownership interests in the Fund at a time that is sooner than would otherwise be desirable, which may result in the Fund’s liquidation or, if the Fund is able to continue operating, may result in losses, increased transaction costs and adverse tax consequences as a result of the sale of portfolio securities.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also may have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets. To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this strategy for its currency exposure.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Structured Instrument Risk. Instruments that have similar economic characteristics to equity securities, such as participation notes or other structured instruments (“structured instruments”) are structured, synthetic instruments that generally attempt to replicate the performance of a particular equity or market (“reference assets”). There can be no assurance that structured instruments will trade at the same price or have the same value as the reference assets. In addition, structured instruments may be subject to transfer restrictions and may be illiquid or thinly traded and less liquid than other types of securities, which may also expose the Fund to risks of mispricing or improper valuation. Structured instruments typically are not secured by the reference assets and are therefore dependent solely upon the counterparty for repayment. Structured instruments also have the same risks associated with a direct investment in the reference assets.

Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.
