Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Hedged Equity 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 157% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Hedged Equity Fund attempts to generate enhanced risk-adjusted returns by allocating its assets among a carefully chosen group of experienced hedged equity managers who will serve as sub-advisers (“Sub-Advisers”) to the Fund and who will employ various complementary long/short equity investment strategies. The Adviser has engaged an experienced specialized alternative investment advisory firm to serve as the Lead Sub-Adviser to assist in the identification and selection of Sub-Advisers and in the portfolio construction process.

Under normal market conditions, the Hedged Equity Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities. The types of equity securities in which the Fund generally invests include common stocks, preferred stocks, rights, warrants, convertibles, partnership interests, other investment companies, including exchange-traded funds (“ETFs”), and American Depositary Receipts (“ADRs”) and other similar investments, including European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”). The Fund may invest up to 25% of its net assets in securities purchased on foreign exchanges, which does not include ADRs, EDRs and GDRs. There is no limitation on the Fund’s ability to invest in ADRs, EDRs and GDRs and therefore the Fund’s exposure to foreign securities may be greater than 25% of the Fund’s net assets. The Fund may invest up to 10% of its net assets (out of the 25% which may be invested in foreign securities) in foreign securities of issuers located in emerging markets. The Fund may also invest up to 15% of its net assets in fixed income securities, including sovereign debt, corporate bonds, exchange-traded notes (“ETNs”) and debt issued by the U.S. Government and its agencies. Such fixed income investments may include high-yield or “junk” bonds and generally range in maturity from 2 to 10 years. The Fund may invest up to 10% of its net assets in currencies and forward currency contracts and may also invest without limit in the securities of small- and medium-sized issuers. The Fund may utilize leverage of no more than 10% of the Fund’s total assets as part of the portfolio management process. From time to time, the Fund may invest a significant portion of its assets in the securities of companies in the same sector of the market. The Fund may also invest up to 20% of its net assets in derivatives including futures, options, swaps and forward foreign currency contracts. These instruments may be used to modify or hedge the Fund’s exposure to a particular investment market related risk, as well as to manage the volatility of the Fund. Derivative instruments based upon the equity securities described above are considered equity securities for the purposes of the Fund’s 80% investment restriction.

Each Sub-Adviser is allocated a portion of the Hedged Equity Fund’s assets to invest. The Sub-Advisers invest in the securities described above based upon their belief that the securities have a strong appreciation potential (long investing, or actually owning a security) or potential to decline in value (short investing, or borrowing a security from a broker and selling it, with the understanding that it must later be bought back (hopefully at a lower price) and returned to the broker). Each Sub-Adviser has complete discretion to invest its portion of the Fund’s assets as it deems appropriate, based on its particular philosophy, style, strategies and views. While each Sub-Adviser is subject to the oversight of the Adviser and Lead Sub-Adviser, neither the Adviser nor Lead Sub-Adviser attempt to coordinate or manage the day-to-day investments of the Sub-Advisers. In engaging Sub-Advisers to manage the Fund, the Adviser and Lead Sub-Adviser look to select Sub-Advisers who employ complementary long/short equity investment strategies.

The Lead Sub-Adviser, as part of its portfolio and risk management functions, may elect to directly invest a portion of the Hedged Equity Fund’s assets. These investments by the Lead Sub-Adviser are typically made in equity and fixed income securities, futures, options and other instruments to modify the Fund’s exposure to a particular investment or market related risk, to hedge the Fund against exposures created in aggregate by the Sub-Advisers, as well as to manage the beta of the Fund. (Beta is a measure of the volatility, or systematic risk, of a security or, in this case, the Fund, in comparison to the market as a whole). Under normal operating conditions, it is anticipated that on average, 15% to 20% of the Fund’s assets would be managed by the Lead Sub-Adviser in accordance with this risk management process. Overall portfolio risk controls, managed by the Lead Sub-Adviser in conjunction with the Adviser, seek to maintain a moderate beta for the Fund compared to the S&P 500® Index which, because beta is a measure of volatility, means that the Fund seeks to have less volatility than the S&P 500® Index over a full market cycle.

The Hedged Equity Fund sells (or closes a position in) a security when a Sub-Adviser determines that a particular security has achieved its investment expectations or the reasons for maintaining that position are no longer valid, including: (1) if the Sub-Adviser’s view of the business fundamentals or management of the underlying company changes; (2) if a more attractive investment opportunity is found; (3) if general market conditions trigger a change in the Sub-Adviser’s assessment criteria; or (4) for other portfolio management reasons.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Losing all or a portion of your investment is a risk of investing in the Hedged Equity Fund. The following principal risks could affect the value of your investment.

Market Risk. The value of the Hedged Equity Fund’s shares will fluctuate as a result of the movement of the overall stock market or of the value of the individual securities held by the Fund, and you could lose money.

Management Risk. The skill of the Adviser and Sub-Advisers (including the Lead Sub-Adviser) will play a significant role in the Hedged Equity Fund’s ability to achieve its investment objective. The Fund’s ability to achieve its investment objective depends on the investment skill and ability of the Adviser and Sub-Advisers (including the Lead Sub-Adviser) and on their ability to correctly identify economic trends.

Multi-Style Management Risk. Because portions of the Hedged Equity Fund’s assets are managed by different Sub-Advisers using different styles, the Fund could experience overlapping security transactions. Certain Sub-Advisers may be purchasing securities at the same time other Sub-Advisers may be selling those same securities which may lead to higher transaction expenses compared to a fund using a single investment management style.

Depositary Receipt Risk. The Hedged Equity Fund’s equity investments may take the form of depositary receipts. Depositary receipts may be purchased through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the depositary security. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts of the deposited securities. Fund investments in depositary receipts, which include ADRs, GDRs and EDRs, are not deemed to be investments in foreign securities for purposes of the Fund’s investment strategy.

Foreign and Emerging Market Securities Risk. Foreign investments may carry risks associated with investing outside the United States, such as currency fluctuation, economic or financial instability, lack of timely or reliable financial information or unfavorable political or legal developments. Those risks are increased for investments in emerging markets.

Currency Risk. Changes in foreign currency exchange rates will affect the value of what the Hedged Equity Fund owns and the Fund’s share price. Generally, when the U.S. dollar rises in value against 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 will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Small and Medium Companies Risk. Investing in securities of small and medium capitalization companies may involve greater volatility than investing in larger and more established companies because small and medium capitalization companies can be subject to more abrupt or erratic share price changes than larger, more established companies.

Derivatives Risk. The Hedged Equity Fund’s use of derivatives (which may include options, futures, swaps and forward foreign currency contracts) may reduce the Fund’s returns and/or increase volatility. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets.

ETF and Mutual Fund Risk. When the Hedged Equity 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. Inverse ETFs are subject to the risk that their performance will fall as the value of their benchmark indices rises. The Fund also will incur brokerage costs when it purchases ETFs.

Fixed Income Securities Risk. Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates. It is likely there will be less governmental action in the near future to maintain low interest rates. The negative impact on fixed income securities from the resulting rate increases for that and other reasons could be swift and significant. Credit risk is the risk that an issuer will not make timely payments of principal and interest. There is also the risk that an issuer may “call,” or repay, its high yielding bonds before their maturity dates. Fixed income securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. Limited trading opportunities for certain fixed income securities may make it more difficult to sell or buy a security at a favorable price or time.

High-Yield Securities Risk. Fixed income securities that are rated below investment grade (i.e., “junk bonds”) are subject to additional risk factors due to the speculative nature of these securities, such as increased possibility of default liquidation of the security, and changes in value based on public perception of the issuer.

Government-Sponsored Entities Risk. Securities issued by government-sponsored entities may not be backed by the full faith and credit of the United States.

Exchange-Traded Note Risk. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying securities’ markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced index. In addition, the notes issued by ETNs and held by a fund are unsecured debt of the issuer.

Leverage and Short Sales Risk. Leverage is the practice of borrowing money to purchase securities. If the securities decrease in value, the Hedged Equity Fund will suffer a greater loss than would have resulted without the use of leverage. A short sale is the sale by the Fund of a security which it does not own in anticipation of purchasing the same security in the future at a lower price to close the short position. A short sale will be successful if the price of the shorted security decreases. However, if the underlying security goes up in price during the period in which the short position is outstanding, the Fund will realize a loss. The risk on a short sale is unlimited because the Fund must buy the shorted security at the higher price to complete the transaction. Therefore, short sales may be subject to greater risks than investments in long positions.

Sector Risk. To the extent the Hedged Equity 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.

Portfolio Turnover Risk. A high portfolio turnover rate (100% or more) increases the Hedged Equity Fund’s transaction costs (including brokerage commissions and dealer costs), which would adversely impact the Fund’s performance. Higher portfolio turnover may result in the realization of more short-term capital gains than if the Fund had lower portfolio turnover.
