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.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests primarily in a diversified portfolio of common stocks and other equity securities of foreign issuers. This portfolio generally does not invest in equity securities of companies based in the United States. The Fund will generally invest at least 80% of its net assets (including any borrowings for investment purposes) in equity securities. The Fund may invest in companies of any size. The Adviser employs a proprietary quantitatively-driven approach to security selection based on research and analysis of historical data. The Adviser screens securities for attractive growth and value characteristics using a factor-based model. In selecting value securities, the Adviser evaluates factors that may include, but are not limited to: market capitalization, sales over the previous twelve months, trading volume and cash flow. In selecting growth securities, the Adviser evaluates factors that may include, but are not limited to: market capitalization, trading volume, valuation metrics, earnings and price momentum over time. The Adviser may eliminate or substitute factors at its discretion. Portfolio securities may be sold generally upon periodic rebalancings of the Fund's portfolio. The Adviser considers the same factors it uses in evaluating a security for purchase and generally sells securities when it believes such securities no longer meet its investment criteria. Under normal market conditions, the Fund invests in securities of issuers from three or more non-U.S. countries, with at least 40% (and usually 100%) of the Fund's net assets invested in foreign securities. Foreign securities are determined to be "foreign" on the basis of an issuer's domicile or location of headquarters (as determined by the Adviser's data sources). The Fund may invest up to 20% of its total assets in the securities of issuers determined by the Adviser to be in developing or emerging market countries. The Fund may from time to time emphasize investment in certain sectors of the market.    The Fund invests primarily in common stocks and other equity securities, including preferred stocks, convertible securities, rights and warrants to purchase common stock and depositary receipts. The Fund may invest up to 10% of its total assets in REITs and foreign real estate companies. The Fund may invest up to 10% of its total assets in other investment companies, including ETFs. The Fund may purchase and sell certain derivative instruments, such as futures contracts and currency-related transactions involving futures contracts and forward contracts, for various portfolio management purposes, including to facilitate portfolio management and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index. The Adviser expects that the Fund's investment strategy may result in a portfolio turnover rate in excess of 100% on an annual basis.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Losing all or a portion of your investment is a risk of investing in the Fund. The following principal risks could affect the value of your investment: ·  Market Risk and Equity Risk. Market risk is the possibility that the market        value of securities owned by the Fund will decline. Investments in common          stocks and other equity securities generally are affected by changes in the        stock markets, which fluctuate substantially over time, sometimes suddenly and    sharply. The values of convertible securities tend to decline as interest rates    rise and, because of the conversion feature, tend to vary with fluctuations in    the market value of the underlying equity security.                                                                                                                ·  Management Risk. The Fund is subject to management risk because it is an           actively managed portfolio. The Adviser's management practices and investment      strategies might not work to meet the Fund's investment objective.                                                                                                 ·  Small- and Medium-Sized Companies Risk. Small- and medium-sized companies often    have less predictable earnings, more limited product lines, markets,               distribution channels or financial resources and the management of such            companies may be dependent upon one or few key people. The market movements of    equity securities of small- and medium-sized companies may be more abrupt and      volatile than the market movements of equity securities of larger, more            established companies or the stock market in general and small-sized companies    in particular, are generally less liquid than the equity securities of larger      companies.                                                                                                                                                         ·  Sector Risk. To the extent the Fund invests a significant portion of its          assets in the securities of companies in the same sector of the market, the        Fund is more susceptible to economic, political, regulatory and other              occurrences influencing those sectors.                                                                                                                             ·  Foreign Securities Risk. The risks of investing in the securities of foreign       issuers, including emerging market issuers and depositary receipts, can include    fluctuations in foreign currencies, foreign currency exchange controls,            political and economic instability, differences in securities regulation and       trading, and foreign taxation issues. These risks are greater in emerging          markets.                                                                                                                                                            ·  REITs and Foreign Real Estate Company Risk. Investing in REITs and foreign real    estate companies makes the Fund more susceptible to risks associated with the      ownership of real estate and with the real estate industry in general, as well    as tax compliance risks, and may involve duplication of management fees and        other expenses. REITs and foreign real estate companies may be less diversified    than other pools of securities, may have lower trading volumes and may be          subject to more abrupt or erratic price movements than the overall securities      markets.                                                                                                                                                           ·  Investment Company Risk. When the Fund invests in an ETF or mutual fund, it        will bear additional expenses based on its pro rata share of the ETF's or          mutual fund's operating expenses, including the potential duplication of           management fees. The risk of owning an ETF or mutual fund generally reflects       the risks of owning the underlying securities the ETF or mutual fund holds.    The Fund also will incur brokerage costs when it purchases ETFs.                                                                                                       ·  Derivative Transactions Risk. Risks of derivatives include the possible            imperfect correlation between the value of the instruments and the underlying      assets; risks of default by the other party to the transaction; risks that the    transactions may result in losses that partially or completely offset gains in    portfolio positions; and risks that the instruments may not be liquid.                                                                                              ·  Portfolio Turnover Risk. A high portfolio turnover rate (100% or more) has the    potential to result in the realization and distribution to shareholders of         higher capital gains, which may subject you to a higher tax liability. High        portfolio turnover also necessarily results in greater transaction costs which    may reduce Fund performance.                                                                                                                                       ·  New Fund Risk. The Fund is new with no operating history and there can be no       assurance that the Fund will grow to or maintain an economically viable size,      in which case the Board may determine to liquidate the Fund.
