rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $100,000 in the Fund for the time periods indicated and that you sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the operating expenses of the Fund remain the same (taking into account the contractual expense limitation until its expiration). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in a non-diversified portfolio of equity and equity-related securities issued by U.S. and non-U.S. companies of any capitalization size. The Fund may invest in all types of equity and equity- related securities, including exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, participatory notes, limited partnership interests, shares of other investment companies (including exchanged-traded funds (“ETFs”)), real estate investment trusts (“REITs”) and equity participations. An equity participation is a type of loan that gives the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula.

The Fund defines non-U.S. companies as companies (i) that are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets, or that derive a significant portion of their revenue or profits from businesses, investments or sales, outside of the United States. Under normal market conditions, the Fund invests significantly (ordinarily at least 40% — unless market conditions are not deemed favorable by the Fund, in which case the Fund would invest at least 30%) in non-U.S. companies. The Fund principally will be invested in issuers located in countries with developed securities markets, but may also invest in issuers located in emerging markets. The Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries).

The Fund generally invests in the equity securities of issuers believed by a Co-Adviser to be undervalued in the marketplace, focusing on issuers that combine attractive valuations with catalysts for change. The Fund applies a bottom-up stock selection process (i.e., one that focuses primarily on issuer-specific factors) in managing the Fund, using a combination of fundamental and quantitative analysis. In selecting investments for the Fund, the Fund considers various factors such as price-to-book value, price-to-sales and earnings ratios, dividend yields, strength of management, and cash flow to identify securities that are trading at a price that appears to be lower than the issuer’s inherent value. The Fund may (but is not required to) invest in derivatives, including put and call options, futures, forward contracts and swaps, in lieu of investing directly in a security, currency or instrument, for hedging and non-hedging purposes.

The Fund may participate as a purchaser in initial public offerings of securities (“IPO”). An IPO is a company’s first offering of stock to the public. The Fund may also seek to increase its income by lending portfolio securities. The Fund may invest up to 15% of its net assets in illiquid securities, including securities that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

The Fund also seeks to diversify its overall portfolio by investing, under normal circumstances, up to 20% of its assets in the Campbell Advantage strategy, a systematic trend following program, which is diversified across global futures and forwards markets (types of derivative instruments). The Campbell Advantage strategy is designed to analyze market data to identify trends occurring within and across markets and asset classes globally. By trading four major asset classes (equity index futures, fixed income futures, commodities and foreign exchange), the portfolio composition is diverse and expected to maintain low correlation with equities over time. Additionally, portfolio risk is dynamically managed through a framework intended to maximize the Campbell Advantage strategy’s ability to complement the global long equity exposure in an attempt to limit the Fund’s downside risk during extended periods of high equity market volatility.

The Fund’s investments may include investments in registered and unregistered funds managed by Campbell or an affiliate to obtain exposure to the Campbell Advantage strategy. The Fund will invest in such affiliated funds only in accordance with the applicable restrictions of the 1940 Act, including Section 12(d)(1).

The Fund is “non-diversified” for purposes of the Investment Company Act of 1940, as amended, (the “1940 Act”) which means that the Fund may invest in fewer securities at any one time than a diversified fund. The Fund may invest up to 15% of its net assets in illiquid securities, including securities that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

The Fund’s Co-Advisers are Boston Partners and Campbell. Boston Partners is primarily responsible for managing the equity portion of the Fund’s portfolio, including equity securities and related derivative contracts. Campbell is primarily responsible for managing the Fund’s exposure to the Campbell Advantage strategy. Campbell is also primarily responsible for determining the allocation of the Fund’s portfolio between equity and other investments. Each Co-Adviser may also from time to time consult and work collaboratively with, or be informed by the decisions of or information from, one or both of the other Co-Advisers in connection with making certain investment decisions in regards to the Fund’s investment strategies and portfolio, in addition to various compliance, operational and administrative matters. While the Co-Advisers may work collaboratively in connection with the management of the Fund’s portfolio as described above, under certain circumstances, such as, for example, when certain personnel at another Co-Adviser are not available, a Co-Adviser may make decisions or otherwise act independently from the other Co-Advisers.

The Fund reserves the right to hold up to 100% of its assets, as a temporary defensive measure, in cash and eligible U.S. dollar-denominated money market instruments and make investments inconsistent with its investment objective. The Co-Advisers will determine when market conditions warrant temporary defensive measures.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

• Active Management Risk. The Co-Advisers’ judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. The Fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies if the Fund’s overall asset allocation, investment selections or strategies fail to produce the intended results.

• Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

• Counterparty Risk. The derivative contracts entered into by the Fund may be privately negotiated in the over-the-counter market. These contracts also involve exposure to credit risk, since contract performance depends in part on the financial condition of the counterparty. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. The Fund is neither restricted from dealing with any particular counterparty nor from concentrating any or all of its transactions with one counterparty. The ability of the Fund to transact business with any one or number of counterparties and the absence of a regulated market to facilitate settlement may increase the potential for losses by the Fund.

• Credit Risk. Credit risk refers to the possibility that the issuer of the security or a counterparty in respect of a derivative instrument will not be able to satisfy its payment obligations to the Fund when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value or default. In addition, the credit quality of securities may be lowered if an issuer’s financial condition changes.

• Currency Risk. Investment in foreign securities also involves currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and which may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

• Derivatives Risk. Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures, options, swap agreements and forward contracts. Derivatives typically have economic leverage inherent in their terms. Such leverage will magnify any losses. See “Leverage/Volatility Risk” below. The primary types of derivatives in which the Fund invests in are swap agreements, futures contracts and forward contracts. Futures contracts, forward contracts and swap agreements can be highly volatile, illiquid and difficult to value, and changes in the value of such instruments held directly or indirectly by the Fund may not correlate with the underlying instrument or reference assets, or the Fund’s other investments. Although the value of futures contracts, forward contracts and swap agreements depend largely upon price movements in the underlying instrument or reference asset, there are additional risks associated with futures contracts, forward contracts and swap agreements that are possibly greater than the risks associated with investing directly in the underlying instruments or reference assets, including illiquidity risk, leveraging risk and counterparty credit risk. A small position in futures contracts, forward contracts or swap agreements could have a potentially large impact on the Fund’s performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in swap agreements, futures contracts and options and forward contracts.

• Emerging Markets Risk. Investment in emerging market securities involves greater risk than that associated with investment in securities of issuers in developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers.

• Equity Securities Risk. The Fund may invest in, or have exposure to, equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities.

• Fixed Income Risk. Fixed income securities, such as U.S. Treasuries, or derivatives based on fixed income securities, are subject to credit risk and interest rate risk. Credit risk, as described more fully above, refers to the possibility that the issuer of a debt security will be unable to make interest payments or repay principal when it becomes due. Interest rate risk refers to fluctuations in the value of a debt security resulting from changes in the general level of interest rates. Prices of fixed income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed income security prices and, accordingly, the Fund’s returns and share price. In addition, the Fund may be subject to “call” risk, which is the risk that during a period of falling interest rates the issuer may redeem a security by repaying it early (which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates), and “extension” risk, which occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated (causing the value of those securities held by the Fund to fall).

• Foreign Securities Risk. International investing is subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, and differences in taxation, auditing and other financial practices. The Fund may invest in, or have exposure to, securities of foreign issuers either directly or depositary receipts. Trading on foreign exchanges is subject to the risks presented by exchange controls, expropriation, increased tax burdens and exposure to local economic declines and political instability. Depositary receipts may be available through “sponsored” or “unsponsored” facilities. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored depositary receipts may provide less information to receipt holders. Participatory notes (“P-notes”) are derivative instruments used by investors to take positions in certain foreign securities. P-notes present similar risks to investing directly in such securities and also expose investors to counterparty risk. Some foreign derivative markets are so-called principals’ markets in which performance is the responsibility only of the individual counterparty with whom the trader has entered into a commodity interest transaction and not of the exchange or clearing corporation.

• Futures and Forward Contracts and Related Risks. The successful use of forward and futures contracts draws upon an investment adviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market, and possible regulatory position limits and restrictions, for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the possibility that the counterparty will default in the performance of its obligations; and (e) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so. The use of futures contracts, forward contracts and derivative instruments will have the economic effect of financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying an investment and results in increased volatility, which means the Fund will have the potential for greater losses than if the Fund did not employ leverage in its investment activity. Leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset class and may cause the value of the Fund’s securities or related derivatives instruments to be volatile. Exposure to the commodities markets (including financial futures markets) may subject the Fund to greater volatility than investments in traditional securities.

• Government Agency Risk. Direct obligations of the U.S. Government such as Treasury bills, notes and bonds are supported by its full faith and credit. Indirect obligations issued by Federal agencies and government-sponsored entities generally are not backed by the full faith and credit of the U.S. Treasury. Accordingly, while U.S. Government agencies and instrumentalities may be chartered or sponsored by Acts of Congress, their securities are neither issued nor guaranteed by the U.S. Treasury. Some of these indirect obligations may be supported by the right of the issuer to borrow from the Treasury; others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations; still others are supported only by the credit of the instrumentality.

• Government Intervention and Regulatory Changes. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (which was passed into law in July 2010) significantly expanded the rulemaking, supervisory and enforcement authority of federal bank, securities and commodities regulators. There can be no assurance that future regulatory actions including, but not limited to, those authorized by the Dodd-Frank Act will not adversely affect the Fund. Major changes resulting from legislative or regulatory actions could materially affect the profitability of the Fund or the value of investments made by the Fund or force the Fund to revise its investment strategy or divest certain of its investments. Any of these developments could expose the Fund to additional costs, taxes, liabilities, enforcement actions and reputational risk.

In addition, the SEC has proposed new regulations regarding mutual funds’ use of derivatives and leverage. These proposed rules, if adopted in substantially the same form as proposed, could have a substantial effect on the ability of the Fund to implement fully its investment strategy as described herein, which may limit the Fund’s ability to achieve its objective.

• Illiquid Securities Risk. Investing in illiquid securities is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities.

• Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by a Co-Adviser. There will likely be less governmental action in the near future to maintain low interest rates. The negative effect on fixed income securities from the resulting rate increases for that and other reasons could be swift and significant.

• Investment Company and Exchange-Traded Fund Risk. Investing in other investment companies, including exchange-traded funds (“ETFs”), may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The risk of owning an investment company or ETF generally reflects the risks of owning the underlying investments the investment company or ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares.

• IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Co-Advisers cannot guarantee continued access to IPOs.

• Large-Cap Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform investments that focus solely on small- or medium-capitalization stocks.

• Leverage/Volatility Risk. Although the Fund will not borrow funds for trading, the Fund should be considered highly leveraged and is suitable only for investors with high tolerance for investment risk. Leverage embedded in the various derivative instruments traded may result in the Fund holding positions whose face or notional value may be many times the Fund’s net asset value (“NAV”). For example, the amount of margin funds necessary to be deposited in order to enter into a futures, forward or option contract position is typically from 2% to 10% of the total face or notional value of the contract, and even a small movement in the price of a commodity can cause a correspondingly large profit or loss. Losses incurred on leveraged investments increase in direct proportion to the degree of leverage employed. Furthermore, derivative instruments and futures contracts are highly volatile and are subject to occasional rapid and substantial fluctuations. Consequently, you could lose all or substantially all of your investment in the Fund should the Fund’s trading positions suddenly turn unprofitable.

• Market Risk. The Fund’s NAV and investment return will fluctuate based upon changes in the value of its investments. You could lose money on your investment in the Fund, or the Fund could underperform other investments.

• Mid-Cap Companies Risk. The stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

• 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.

• Non-Diversification Risk. The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

• Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The value of options can be highly volatile, and their use can result in loss if the Co-Adviser is incorrect in its expectation of price fluctuations.

• OTC Trading Risk. Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the “over-the-counter” or “OTC” market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. The Fund is subject to counterparty credit risk with respect to such derivative contracts.

• REITs Risk. REITs may be affected by economic forces and other real estate industry factors. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index.

• Securities Lending Risk. The Fund may lend portfolio securities to institutions, such as certain broker- dealers. The Fund may experience a loss or delay in the recovery of its securities, if the borrowing institution breaches its agreement with the Fund.

• Short Sales Risk. The Fund may take a short position in a derivative instrument, such as a future, forward or swap or security. A short position on a derivative instrument or security involves the risk of a theoretically unlimited increase in the value of the underlying instrument. Short sales also involve transaction and other costs that will reduce potential Fund gains and increase potential Fund losses.

• Small-Cap Companies Risk. The stocks of smaller companies may be subject to more abrupt, erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent on a small or inexperienced management group, and their securities may trade less frequently and in lower volume than securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.
