The investment objective of the Campbell Systematic Macro Fund (the “Fund”) is to seek capital appreciation over the medium to long-term.

Expense [Heading] rr_ExpenseHeading Expenses and Fees
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (the “Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts if you invest at least $25,000 in Class A Shares of the Fund. More Information about these discounts is available from your financial professional, in the section of this Prospectus entitled “Shareholder Information – Sales Charges” and in the Fund’s Statement of Additional Information (“SAI”) entitled “Purchase and Redemption Information – Reducing or Eliminating the Front End Sales Charge.” Financial Intermediaries may impose different sales charge waivers for Class A Shares, and these variations are described in the section of this Prospectus entitled “Shareholder – Information – Sales Charges”.

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 Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate of the Fund was 0% of the average value of its portfolio. In accordance with industry practice, derivative instruments and instruments with a maturity of one year or less at the time of acquisition are excluded from the calculation of the portfolio turnover rate, which leads to the 0% portfolio turnover rate reported above. If those instruments were included in the calculation, the Fund would have a higher portfolio turnover rate.

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 $10,000 in Class A Shares and Class C Shares and $100,000 in Class I Shares 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 [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by (i) investing its assets pursuant to the Campbell Systematic Macro Program, (ii) allocating up to 25% of its total assets in its wholly-owned subsidiary, Campbell Systematic Macro Offshore Limited (the “Subsidiary”), which is organized under the acts of the Cayman Islands and employs the Adviser’s Campbell Systematic Macro Program (as described below), and (iii) allocating the remainder of its assets directly in a portfolio of investment grade securities (including government securities) for cash management purposes. Securities rated in the four highest categories by the ratings agencies are considered investment grade.

 

The Fund invests pursuant to the Adviser’s Campbell Systematic Macro Program, which uses quantitative modeling to develop and maintain systematic trading strategies driven by scientific analysis of financial data across global financial and commodity markets. The Campbell Systematic Macro Program seeks to systematically identify price trends and to develop macro and fundamental themes that exploit asset mispricing. As a pioneer in systematic trend following, innovating modeling techniques can be developed to extract relationships and to identify trends occurring within and across markets and asset classes globally. Other complimentary systematic strategies are incorporated, such as relative value (i.e., a trading strategy that looks for opportunities based on an asset’s value as compared to the value of similar assets. In contrast, absolute value looks only at an asset’s intrinsic value and does not compare it to other assets) and mean reversion (i.e., a trading strategy based on the concept that prices and returns eventually move back toward the mean or average. This mean or average can be the historical average of the price or return, or another relevant average such as the growth in the economy or the average return of an industry). A systematic process eliminates emotion, “key person” risk, and provides an ability to participate in trends during periods of extended momentum without any directional bias. Key person risk is the risk that results when a fund’s investment program is highly dependent on the investment skill and dedication of a small number of “key” persons at an adviser, which can result in decreased investment results if these “key” persons become unable to apply their full attention to the management of a fund’s investments for health or other reasons. In addition, a diversity of investment style and the ability to invest long and short across global asset classes and markets enables investment opportunities in a variety of economic environments. The Fund is generally intended to have a low correlation to the equity, bond and credit markets. There is no assurance, however, that the Fund will achieve its investment objective.

 

The Fund intends to trade in a broad range of instruments, including but not limited to, futures (including commodity futures, index futures, equity futures, bond futures and interest rate futures), currency forwards, options and swaps (including commodity swaps, swaps on commodity futures, equity swaps, swaps on index futures, total

return swaps and interest rate swaps), either by investing directly in the instruments or, indirectly, by investing in the Subsidiary which invests in the instruments. From time to time, the Fund can have significant exposure to non-U.S. dollar denominated currencies, including emerging markets currencies.

 

The Adviser will attempt to mitigate risk through diversification of holdings and through monitoring of the portfolio, the Fund’s counterparties, and other risk measures. Individual market positions are constrained to ensure that no one market or asset class represents an outsized portion of the Fund’s portfolio risk. The Adviser evaluates changes in signals daily, and execution is controlled by its intraday risk management and execution platform. The Fund may utilize proprietary or third party trading algorithms in order to minimize market impact and reduce trading costs.

 

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 not invest more than 15% of its net assets in illiquid investments.

 

Investments in the Subsidiary, which has the same investment objective as the Fund, are intended to provide the Fund with indirect exposure to futures contracts and commodities in a manner consistent with the limitations and requirements of the Internal Revenue Code of 1986, as amended (the “Code”) that apply to the Fund, which limit the amount of income the Fund may receive from certain sources. Applicable federal tax requirements generally limit the degree to which the Fund may invest in the Subsidiary to an amount not exceeding 25% of its total assets. To the extent they are applicable to the investment activities of the Subsidiary, the Subsidiary will be subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund. The Fund complies with Section 8 and Section 18 of the 1940 Act, governing investment policies and capital structure and leverage, respectively, on an aggregate basis with the Subsidiary. The Subsidiary also complies with Section 17 of the 1940 Act relating to affiliated transactions and custody.

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund (and, indirectly, in the Subsidiary), as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Commodities Risk: Exposure to the commodities markets (including financial futures markets) may subject the Fund through its investment in the Subsidiary to greater volatility than investments in traditional securities. Prices of commodities and related contracts may fluctuate significantly over short periods for a variety of reasons, including changes in interest rates or factors affecting a particular industry or commodity, such as weather, disease (including pandemics), tariffs, embargoes or other trade barriers, acts of war or terrorism, or political and regulatory developments.

 

 

Counterparty Risk: The derivative contracts entered into by the Fund or its Subsidiary 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. This may impair the Fund’s liquidity or cause a deterioration in the Fund’s net asset value (“NAV”). In addition, the Fund may incur expenses in an effort to protect the Fund’s interests or enforce its rights against an issuer, guarantor or counterparty or may be hindered or delayed in exercising these rights. 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: The Fund’s exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency that the Fund is short. Currency rates in foreign countries may fluctuate significantly over short periods of time for any number of reasons, including changes in interest rates and the imposition of currency controls or other political developments in the U.S. or abroad.

 

 

Cyber Security Risk: Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

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 use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The primary types of derivatives in which the Fund or its Subsidiary invest 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 depends 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 Market Risk: The Fund intends to have exposure to emerging markets due to the Fund’s investments in certain stock index futures and foreign exchange instruments. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging financial markets have far lower trading volumes and less liquidity than developed markets; are subject to greater social, economic and political instability; have less governmental supervision and regulation of securities markets; and have weaker auditing and financial reporting standards. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

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 herein, 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 Market Risk: As a general rule, there is less legal and regulatory protection for investors in foreign markets than that available domestically. Additionally, 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. 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. International trading activities are subject to foreign exchange risk. Certain foreign securities in which the Fund may invest may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Futures and Forward Contracts and Related Risks: The successful use of forward and futures contracts draws upon the 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 and forward contracts are:

 

 

Futures and forward contracts have a high degree of price variability and are subject to occasional rapid and substantial changes;

 

 

the imperfect correlation between the change in market value of the forward or futures contracts and the market value of the underlying instrument or reference assets with respect to such contracts;

 

 

possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired;

 

 

possible market disruption or other extraordinary events, including but not limited to, governmental intervention;

 

 

potentially unlimited losses caused by unanticipated market movements;

 

 

the Fund’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors;

 

 

the possibility that the counterparty will default in the performance of its obligations; and

 

 

if the Fund has insufficient cash, it may either have to sell securities from its portfolio to meet daily variation margin requirements with respect to its derivative instruments or close certain positions 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. Accordingly, the Fund’s NAV may be volatile because of its investment exposure to the Fund.

 

There is no assurance that the Fund’s investment in a derivative instrument with leveraged exposure to certain investments and markets will enable the Fund to achieve its investment objective.

 

 

General Market Risk: The Fund’s NAV and investment return will fluctuate based upon changes in the value of its portfolio securities. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. You could lose money on your investment in the Fund, or the Fund could underperform other investments.

 

 

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. The maximum potential liability of the issuers of some U.S. government securities may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future.

 

 

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 revised and 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 impact 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, in October 2020, the SEC adopted new regulations governing the use of derivatives by registered investment companies. The Fund will be required to implement and comply with new Rule 18f-4 by the third quarter of 2022. Once implemented, Rule 18f-4 will impose limits on the amount of derivatives a fund can enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation and require funds whose use of derivatives is more than a limited specified exposure to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. These rules 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.

 

 

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 the Adviser. Securities with longer maturities tend to be more sensitive to changes in interest rates, causing them to be more volatile than securities with shorter maturities. Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Recent and any future declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield and a decline in the Fund’s share price. In addition, certain countries and regulatory bodies may use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested.

 

 

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 or its Subsidiary holding positions whose face or notional value may be many times the Fund’s 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. As a result of this leveraging, 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.

 

The Fund’s NAV is expected over short-term periods to be volatile because of the significant use of direct and indirect investments that have a leveraging effect. Volatility is a statistical measurement of the magnitude of up and down asset price fluctuations over time. Rapid and dramatic price swings will result in high volatility. The Fund’s returns are expected to be volatile; however, the actual or realized volatility level for longer or shorter periods may be materially higher or lower depending on market conditions and investors may suffer a significant and possibly a complete loss on their investment in the Fund.

 

 

Liquidity Risk: The Fund is subject to liquidity risk primarily due to its investments in derivatives. Investments in derivative instruments involve the risk that the Fund may be unable to sell the derivative instrument or sell it at a reasonable price.

 

 

Management Risk: The Adviser employs systematic modeling to make investment decisions about the attractiveness, value and potential positive or negative performance of the Fund. The models employed by the Adviser may prove to be inaccurate and may not produce the desired results.

 

 

Non-Diversification Risk: The Fund is a non-diversified investment company, which means that more of the Fund’s assets may be invested in the securities of a single issuer than could be invested in the securities of a single issuer by a diversified investment company. The Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

 

 

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. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.

 

 

Portfolio Turnover Risk: The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

 

 

Regulatory Risk: Governments, agencies or other regulatory bodies may adopt or change laws or regulations that could adversely affect the issuer, or market value, of an instrument held by the Fund or its Subsidiary or that could adversely impact the Fund’s performance.

 

 

Short Sales Risk: The Fund may take a short position in a derivative instrument, such as a future, or forward, or swap or a 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.

 

 

Strategy Risk: The profitability of any Fund investment depends primarily on the ability of the Adviser to anticipate price movements in the relevant markets and underlying derivative instruments and futures contracts. Such price movements may be influenced by, among other things:

 

 

changes in interest rates;

 

 

governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies;

 

 

weather and climate conditions;

 

 

natural disasters, such as hurricanes;

 

 

changing supply and demand relationships;

 

 

changes in balances of payments and trade;

 

 

U.S. and international rates of inflation and deflation;

 

 

currency devaluations and revaluations;

 

 

U.S. and international political and economic events; and

 

 

changes in philosophies and emotions of various market participants.

 

The Fund may not take all of these factors into account.

 

 

Subsidiary Risk: By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws or acts of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund.

 

 

Tax Risk: In order to qualify as a regulated investment company (“RIC”), the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. Under the test regarding the source of a RIC’s income, at least 90% of the gross income of the RIC each year must be qualifying income, which consists of dividends, interest, gains on investment assets and other categories of investment income. In 2006, the Internal Revenue Service (“IRS”) published a ruling that income realized from swaps with respect to a commodities index would not be qualifying income. The Fund’s investment in the Subsidiary is expected to provide the Fund with exposure to the commodities markets within the limitations of the Code for qualification as a RIC, but there is a risk that the IRS could assert that the income derived from the Fund’s investment in the Subsidiary and certain commodity-linked structured notes will not be considered qualifying income for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. The IRS has finalized Treasury Regulations that provide that the income from a foreign subsidiary that is a controlled foreign corporation is qualifying income for purposes of a fund remaining qualified as a RIC for U.S. federal income tax purposes (1) to the extent the income is actually distributed by the foreign subsidiary to the RIC each year and (2) even if not distributed currently, to the extent the income is derived with respect to the fund’s business of investing in stock, securities or currencies. If the Fund were to fail to qualify as a RIC and became subject to federal income tax, shareholders of the Fund would be subject to diminished returns. Changes in the laws or acts of the United States and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiary to operate as described in this Prospectus and the Statement of Additional Information (“SAI”) and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands acts change such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in equity securities, such as common stocks, preferred stocks or securities convertible into stocks, of U.S. companies, or invest substantially all of their assets in such equity securities. The Fund will diversify its investments by investing primarily in investment companies focusing on different segments of the equity markets, including large (“large-cap”), small (“small-cap”) and micro-capitalization (“micro-cap”) equity securities that the Fund’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of long-term capital appreciation. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses.

 

Under normal market conditions, the Adviser expects substantially all of the Fund’s net assets to be invested in the securities of investment companies that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

 

U.S. Large Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of large cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Large cap companies are generally considered companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

 

U.S. Small Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

 

U.S. Large Company Asset Class: The underlying investment companies generally will purchase all of the stocks that comprise the S&P 500® Index in approximately the proportions they are represented in the S&P 500® Index. Generally, these are the U.S. stocks with the largest market capitalizations and, as a group, they represent approximately 80% of the total market capitalization of all publicly traded U.S. stocks.

 

U.S. Small Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies primarily based on market capitalization. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. small cap asset class and the U.S. micro cap asset class invest.

 

U.S. Micro Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of micro cap companies. Micro cap companies are generally considered companies whose market capitalizations are generally in the lowest 5% of total market capitalization or companies whose market capitalizations are smaller than the 1,500th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. micro cap asset class and the U.S. small cap asset class invest.

 

The underlying investment companies may use derivatives, such as futures contracts and options on futures contracts for U.S. equity securities and indices, to adjust market exposure based on actual or expected cash inflows to or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, options and swaps to help the ETF track its underlying index.

 

The Fund reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Fund employs a temporary defensive measure, the Fund may not achieve its investment objective. Periodically the Adviser will review the allocations for the Fund in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Fund in the underlying investment companies without notice to shareholders.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Stocks of large cap, small cap or micro cap companies in which the Fund’s underlying investment companies invest or in which the Fund invests directly may temporarily fall out of favor with investors or may be more volatile than the rest of the U.S. market as a whole.

 

 

The smaller the capitalization of a company, generally the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records and are more likely to fail than companies with larger market capitalizations.

 

 

Although the Fund will invest in other investment companies that follow a value oriented strategy, value stocks may perform differently from the market as a whole and such a strategy may cause the Fund at times to underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic and industry developments than the market as a whole and other types of stocks, and may underperform the market for long periods of time.

 

 

The Fund will invest in underlying investment companies that purchase stocks with high relative profitability. High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Fund to at times underperform equity funds that use other investment strategies.

 

 

Companies in which the Fund’s underlying investment companies invest may suffer unexpected losses or lower than expected earnings or their securities may become difficult or impossible to sell at the time and for the price that the underlying investment adviser(s) would like.

 

 

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Fund could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

 

 

Because under normal circumstances the Fund invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in U.S. equity securities, the net asset value (“NAV”) of the Fund will change with changes in the share prices of the investment companies in which the Fund invests.

 

 

There is a risk that large, small or micro capitalization stocks may not perform as well as other asset classes or the U.S. stock market as a whole. In the past, large, small and micro capitalization stocks have gone through cycles of doing better or worse than the stock market in general.

 

 

There is a risk that the Fund, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

 

 

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

The performance of the Fund will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

 

 

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

 

 

More information about the Fund’s investments and risks is contained under the section entitled “More About Each Fund’s Investments and Risks.”

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and that you sell 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 and returns might be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in equity securities, such as common stocks, preferred stocks or securities convertible into stocks, of foreign companies, or invest substantially all of their assets in such equity securities. The Fund will diversify its investments by investing primarily in investment companies that focus on different segments of the foreign equity markets, including emerging markets, with little or no focus on domestic equity markets. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses.

 

Under normal market conditions, the Fund’s investment adviser, Matson Money, Inc. (the “Adviser”), expects substantially all of the Fund’s net assets to be invested in the securities of investment companies that invest in the types of securities described in each asset class below, with less than 5% of the net assets invested in cash or money market instruments.

 

International Small Cap Value Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of small companies in foreign countries with developed markets that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios, as well as economic conditions and developments in the issuer’s industry. The criteria used for assessing value are subject to change from time to time. The underlying investment adviser(s) determine the maximum market capitalization of a small company with respect to each country. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

International Large Cap Value Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of large companies in foreign countries with developed markets that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios, as well as economic conditions and developments in the issuer’s industry. The criteria used for assessing value are subject to change from time to time. The underlying investment adviser(s) determine the minimum market capitalization of a large company with respect to each country or region. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

International Small Company Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of small companies in foreign countries with developed markets. The underlying investment adviser(s) determine the maximum market capitalization of a small company with respect to each country. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

International Large Cap Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of large companies in foreign countries with developed markets. The underlying investment adviser(s) determine the minimum market capitalization of a large company with respect to each country or region. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

Emerging Markets Asset Class, Emerging Markets Value Asset Class, and Emerging Markets Small Cap Asset Class (collectively, the “Emerging Markets Asset Classes”): Underlying investment companies comprising each Emerging Markets Asset Class generally will purchase stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of companies located in emerging market countries, including frontier markets (emerging market countries in an earlier stage of development). The underlying investment companies investing in securities of the Emerging Markets Asset Class and the Emerging Markets Small Cap Asset Class will generally purchase the equity securities of larger and smaller companies, respectively, within each country. The underlying investment adviser(s) determine company size primarily based on market capitalization. The thresholds will vary by country or region, and the dollar amounts will change from time to time due to market conditions.

 

The underlying investment companies in the Emerging Markets Value Asset Class generally will purchase emerging market equity securities that are deemed by the underlying investment adviser(s) to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time.

 

The underlying investment companies may use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to hedge currency exposure or to adjust market exposure based on actual or expected cash inflows or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

 

The Fund reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Fund employs a temporary defensive measure, the Fund may not achieve its investment objective. Periodically the Adviser will review the allocations for the Fund in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Fund in the underlying investment companies without notice to shareholders.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

The value of particular foreign equity securities which the Fund’s underlying investment companies may purchase or foreign stock markets on which the securities they may purchase are traded may decline in value.

 

 

Stocks of large cap or small cap foreign companies in which the Fund’s underlying investment companies may invest may temporarily fall out of favor with investors or may be more volatile than particular foreign stock markets or foreign stock markets as a whole.

 

 

The smaller the capitalization of a company, generally the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records and are more likely to fail than companies with larger market capitalizations.

 

 

Stocks of large cap or small cap foreign companies in which the Fund’s underlying investment companies may invest may suffer unexpected losses or lower than expected earnings or such securities may become difficult or impossible to sell at the time and for the price the underlying investment advisers would like.

 

 

Although the Fund will invest in other investment companies that follow a value oriented strategy, value stocks may perform differently from the market as a whole and such a strategy may cause the Fund at times to underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic and industry developments than the market as a whole and other types of stocks, and may underperform the market for long periods of time.

 

 

The Fund will invest in underlying investment companies that purchase stocks with high relative profitability. High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Fund to at times underperform equity funds that use other investment strategies.

 

 

Because the Fund owns shares of underlying investment companies that invest in foreign issuers, the Fund is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards. In addition, foreign securities in which the underlying investment companies invest may be listed on foreign exchanges that trade on weekends or other days when the underlying investment companies do not calculate their net asset value (“NAV”). As a result, the value of the underlying investment companies’ holdings, and therefore the Fund’s holdings, may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Investments in emerging market securities by underlying investment companies in which the Fund invests are subject to higher risks than those in developed market countries because there is greater uncertainty in less established markets and economics. The foregoing risks may be greater in frontier markets, which are among the smallest and least mature investment markets.

 

 

Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Fund invests are denominated will fluctuate daily. In general, the underlying investment companies do not hedge currency risk. As a result, if currencies in which foreign holdings are denominated depreciate against the U.S. Dollar, the value of your investment in the Fund may be adversely affected.

 

 

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Investments in depositary receipts by underlying investment companies in which the Fund invests are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily available public information about the issuer.

 

 

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Fund could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

 

 

Because under normal circumstances the Fund invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in equity securities of foreign companies, the NAV of the Fund will change with changes in the share prices of the investment companies in which the Fund invests.

 

 

There is a risk that the Fund, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

 

 

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

The performance of the Fund will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

 

 

Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in fixed income securities that the Fund’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of providing total return, or invest substantially all of their assets in such fixed income securities. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses.

 

Under normal market conditions, the Adviser expects substantially all of the Fund’s net assets to be invested in the securities of investment companies that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

 

One-Year Fixed Income Asset Class: The underlying investment companies generally will purchase U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the U.S.; foreign government and agency obligations, bank obligations, including the obligations of U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements, and obligations of supranational organizations such as the World Bank, the European Investment Bank, and the Inter-American Development Bank. Generally, obligations comprising this asset class will mature within one year from the date of settlement, but substantial investments may be made in obligations maturing within two years from the date of settlement when greater returns are available.

 

Two-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, and other debt obligations of domestic and foreign issuers with maturities of no more than two years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

 

Intermediate Government Fixed Income Asset Class: The underlying investment companies generally will purchase debt obligations of the U.S. government and U.S. government agencies. Generally, investment companies in the asset class will purchase securities with maturities of between five and fifteen years, however such investment companies ordinarily will have an average weighted maturity of between three and ten years. The underlying investment companies may invest a portion of their assets in the obligations of foreign governments. Those obligations at the time of purchase must be either rated in the highest rating category of a nationally recognized statistical rating organization or, in the case of any obligation that is unrated, of comparable quality.

 

Five-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. Generally, obligations comprising this asset class have a weighted average maturity not exceeding five years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

 

Short-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 1-5 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non- U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to one year and less than five years.

 

Intermediate-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 5-10 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non-U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to five years and less than ten years.

 

Inflation Protected Securities Asset Class: The underlying investment companies generally will track the investment results of the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L), which measures the performance of the inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.” TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation - a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index (“CPI”), and TIPS’ principal payments are adjusted according to changes in the CPI. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase.

 

The underlying investment companies may also use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to hedge currency exposure or to adjust market exposure based on actual or expected cash inflows or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

 

Certain underlying investment companies may concentrate their investments (invest more than 25% of its total assets) in obligations of U.S. and foreign banks and bank holding companies when the yield to maturity on eligible portfolio investments in banking securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. While the Fund will not concentrate its investments in any one industry, the Fund may be focused on banking sectors under certain circumstances.

 

The Fund reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Fund employs a temporary defensive measure, the Fund may not achieve its investment objective. Periodically the Adviser will review the allocations for the Fund in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Fund in the underlying investment companies without notice to shareholders.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Fixed income securities in which the Fund’s underlying investment companies may invest are subject to certain risks, including: interest rate risk, reinvestment risk, prepayment and extension risk, credit/default risk, and the risks associated with investing in repurchase agreements.

 

 

Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes.

 

 

Reinvestment risk involves the risk that proceeds from matured investments may be re-invested at lower interest rates.

 

 

Prepayment risk involves the risk that in declining interest rates environments prepayments of principal could increase and require the Fund to reinvest proceeds of the prepayments at lower interest rates.

 

 

Extension risk involves the risk that prepayments of principal will decrease when interest rates rise resulting in a longer effective maturity of a security.

 

 

Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. Credit risk also involves the risk that the credit rating of a security may be lowered.

 

 

Repurchase agreement risk involves the risk that the other party to a repurchase agreement will be unable to complete the transaction and the underlying investment company in which the Fund invests may suffer a loss as a result.

 

 

Because the Fund owns shares of underlying investment companies that invest in foreign issuers, the Fund is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards. In addition, foreign securities in which the underlying investment companies invest may be listed on foreign exchanges that trade on weekends or other days when the underlying investment companies do not calculate their net asset value (“NAV”). As a result, the value of the underlying investment companies’ holdings, and therefore the Fund’s holdings, may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Fund invests are denominated will fluctuate daily. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Fund than if it had not engaged in these contracts.

 

 

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Inflation protected securities, such as TIPS, generally will fluctuate in response to changes in real interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. In addition, interest payments on inflation-protected securities will generally vary up or down along with the rate of inflation. Real interest rates are generally measured as a nominal interest less an inflation rate. As such, investors should be aware that an investment in TIPS over a particular timeframe may decrease in value even in an inflationary environment. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Because of their inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

 

 

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Fund could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

 

 

Because under normal circumstances the Fund invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in fixed income securities, the NAV of the Fund will change with changes in the share prices of the investment companies in which the Fund invests.

 

 

Not all obligations of U.S. government agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed only by the credit of the issuing agency or instrumentality. Accordingly, there may be some risk of default by the issuer in such cases.

 

 

There is a risk that the Fund, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

 

 

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

The performance of the Fund will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

 

 

Banks are very sensitive to changes in money market and general economic conditions. Adverse general economic conditions can cause financial difficulties for a bank’s borrowers and the borrowers’ failure to repay their loans can adversely affect the bank’s financial situation. Banks are subject to extensive regulation and decisions by regulators may limit the loans banks make and the interest rates and fees they charge, which could reduce bank profitability.

 

 

Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

The Portfolio 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended August 31, 2021, the Portfolio’s portfolio turnover rate was 18% of the average value of its portfolio.

Had those fees and expenses been included, the costs shown below would be higher.

 

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and that you sell your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Portfolio pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in equity securities, such as common stocks, preferred stocks or securities convertible into stocks, of U.S. companies, or invest substantially all of their assets in such equity securities. The Portfolio will diversify its investments by investing primarily in investment companies focusing on different segments of the equity markets, including large (“large-cap”), small (“small-cap”) and micro-capitalization (“micro-cap”) equity securities that the Portfolio’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of long-term capital appreciation. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses.

 

Under normal market conditions, the Adviser expects substantially all of the Portfolio’s net assets to be invested in the securities of investment companies, including other investment companies funded by insurance company separate accounts, that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

 

U.S. Large Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of large cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Large cap companies are generally considered companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

 

U.S. Small Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

 

U.S. Large Company Asset Class: The underlying investment companies generally will purchase all of the stocks that comprise the S&P 500® Index in approximately the proportions they are represented in the S&P 500® Index. Generally, these are the U.S. stocks with the largest market capitalizations and, as a group, they represent approximately 80% of the total market capitalization of all publicly traded U.S. stocks.

 

U.S. Small Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies primarily based on market capitalization. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. small cap asset class and the U.S. micro cap asset class invest.

 

U.S. Micro Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of micro cap companies. Micro cap companies are generally considered companies whose market capitalizations are generally in the lowest 5% of total market capitalization or companies whose market capitalizations are smaller than the 1,500th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. micro cap asset class and the U.S. small cap asset class invest.

 

The underlying investment companies may use derivatives, such as futures contracts and options on futures contracts for U.S. equity securities and indices, to adjust market exposure based on actual or expected cash inflows to or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, options and swaps to help the ETF track its underlying index.

 

The Portfolio reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Portfolio employs a temporary defensive measure, the Portfolio may not achieve its investment objective. Periodically the Adviser will review the allocations for the Portfolio in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Portfolio in the underlying investment companies without notice to shareholders or the holders of the variable annuity or variable life insurance policies.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Portfolio, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Portfolio or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Portfolio, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Stocks of large cap, small cap or micro cap companies in which the Portfolio’s underlying investment companies invest or in which the Portfolio invests directly may temporarily fall out of favor with investors or may be more volatile than the rest of the U.S. market as a whole.

 

 

The smaller the capitalization of a company, generally the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records and are more likely to fail than companies with larger market capitalizations.

 

 

Although the Portfolio will invest in other investment companies that follow a value oriented strategy, value stocks may perform differently from the market as a whole and such a strategy may cause the Portfolio at times to underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic and industry developments than the market as a whole and other types of stocks, and may underperform the market for long periods of time.

 

 

The Portfolio will invest in underlying investment companies that purchase stocks with high relative profitability. High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio to at times underperform equity funds that use other investment strategies.

 

 

Companies in which the Portfolio’s underlying investment companies invest may suffer unexpected losses or lower than expected earnings or their securities may become difficult or impossible to sell at the time and for the price that the underlying investment adviser(s) would like.

 

 

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Portfolio could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

 

 

Because under normal circumstances the Portfolio invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in U.S. equity securities, the net asset value (“NAV”) of the Portfolio will change with changes in the share prices of the investment companies in which the Portfolio invests.

 

 

There is a risk that large, small or micro capitalization stocks may not perform as well as other asset classes or the U.S. stock market as a whole. In the past, large, small and micro capitalization stocks have gone through cycles of doing better or worse than the stock market in general.

 

 

There is a risk that the Portfolio, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

 

 

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

The performance of the Portfolio will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

 

 

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. the Portfolio may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Cyber security risk is the risk of an unauthorized breach and access to Portfolio assets, Portfolio or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Portfolio investors from purchasing, redeeming or exchanging shares or receiving distributions. The Portfolio and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Portfolio or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio or its service providers may adversely impact and cause financial losses to the Portfolio or its shareholders. Issuers of securities in which the Portfolio invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Portfolio’s investment strategies and operations.

Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. This table does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Portfolio as an investment option. Had those fees and expenses been included, overall fees and expenses would be higher.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Portfolio 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended August 31, 2021, the Portfolio’s portfolio turnover rate was 18% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. This Example does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Portfolio as an investment option. Had those fees and expenses been included, the costs shown below would be higher.

 

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and that you sell your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Portfolio pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in equity securities, such as common stocks, preferred stocks or securities convertible into stocks, of foreign companies, or invest substantially all of their assets in such equity securities. The Portfolio will diversify its investments by investing primarily in investment companies that focus on different segments of the foreign equity markets, including emerging markets, with little or no focus on domestic equity markets. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses.

 

Under normal market conditions, the Portfolio’s investment adviser, Matson Money, Inc. (the “Adviser”), expects substantially all of the Portfolio’s net assets to be invested in the securities of investment companies, including other investment companies funded by insurance company separate accounts, that invest in the types of securities described in each asset class below, with less than 5% of the net assets invested in cash or money market instruments.

 

International Small Cap Value Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of small companies in foreign countries with developed markets that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios, as well as economic conditions and developments in the issuer’s industry. The criteria used for assessing value are subject to change from time to time. The underlying investment adviser(s) determine the maximum market capitalization of a small company with respect to each country. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

International Large Cap Value Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of large companies in foreign countries with developed markets that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios, as well as economic conditions and developments in the issuer’s industry. The criteria used for assessing value are subject to change from time to time. The underlying investment adviser(s) determine the minimum market capitalization of a large company with respect to each country or region. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

International Small Company Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of small companies in foreign countries with developed markets. The underlying investment adviser(s) determine the maximum market capitalization of a small company with respect to each country. This threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

International Large Cap Asset Class: The underlying investment companies generally will purchase the stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of large companies in foreign countries with developed markets. The underlying investment adviser(s) determine the minimum market capitalization of a large company with respect to each country or region. The threshold will vary by country or region, and the dollar amount will change from time to time due to market conditions.

 

Emerging Markets Asset Class, Emerging Markets Value Asset Class, and Emerging Markets Small Cap Asset Class (collectively, the “Emerging Markets Asset Classes”): Underlying investment companies comprising each Emerging Markets Asset Class generally will purchase stocks and other equity securities, directly or through sponsored or unsponsored depositary receipts, of companies located in emerging market countries, including frontier markets (emerging market countries in an earlier stage of development). The underlying investment companies investing in securities of the Emerging Markets Asset Class and the Emerging Markets Small Cap Asset Class will generally purchase the equity securities of larger and smaller companies, respectively, within each country. The underlying investment adviser(s) determine company size primarily based on market capitalization. The thresholds will vary by country or region, and the dollar amounts will change from time to time due to market conditions.

 

The underlying investment companies in the Emerging Markets Value Asset Class generally will purchase emerging market equity securities that are deemed by the underlying investment adviser(s) to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time.

 

The underlying investment companies may use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to hedge currency exposure or to adjust market exposure based on actual or expected cash inflows or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

 

The Portfolio reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Portfolio employs a temporary defensive measure, the Portfolio may not achieve its investment objective. Periodically the Adviser will review the allocations for the Portfolio in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Portfolio in the underlying investment companies without notice to shareholders or the holders of the variable annuity or variable life insurance policies.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Portfolio, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Portfolio or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Portfolio, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

The value of particular foreign equity securities which the Portfolio’s underlying investment companies may purchase or foreign stock markets on which the securities they may purchase are traded may decline in value.

 

 

Stocks of large cap or small cap foreign companies in which the Portfolio’s underlying investment companies may invest may temporarily fall out of favor with investors or may be more volatile than particular foreign stock markets or foreign stock markets as a whole.

 

 

The smaller the capitalization of a company, generally the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records and are more likely to fail than companies with larger market capitalizations.

 

 

Stocks of large cap or small cap foreign companies in which the Portfolio’s underlying investment companies may invest may suffer unexpected losses or lower than expected earnings or such securities may become difficult or impossible to sell at the time and for the price the underlying investment advisers would like.

 

 

Although the Portfolio will invest in other investment companies that follow a value oriented strategy, value stocks may perform differently from the market as a whole and such a strategy may cause the Portfolio at times to underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic and industry developments than the market as a whole and other types of stocks, and may underperform the market for long periods of time.

 

 

The Portfolio will invest in underlying investment companies that purchase stocks with high relative profitability. High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio to at times underperform equity funds that use other investment strategies.

 

 

Because the Portfolio owns shares of underlying investment companies that invest in foreign issuers, the Portfolio is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards. In addition, foreign securities in which the underlying investment companies invest may be listed on foreign exchanges that trade on weekends or other days when the underlying investment companies do not calculate their net asset value (“NAV”). As a result, the value of the underlying investment companies’ holdings, and therefore the Portfolio’s holdings, may change on days when shareholders are not able to purchase or redeem the Portfolio’s shares.

 

 

Investments in emerging market securities by underlying investment companies in which the Portfolio invests are subject to higher risks than those in developed market countries because there is greater uncertainty in less established markets and economics. The foregoing risks may be greater in frontier markets, which are among the smallest and least mature investment markets.

 

 

Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Portfolio invests are denominated will fluctuate daily. In general, the underlying investment companies do not hedge currency risk. As a result, if currencies in which foreign holdings are denominated depreciate against the U.S. Dollar, the value of your investment in the Portfolio may be adversely affected.

 

 

Investments in depositary receipts by underlying investment companies in which the Portfolio invests are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily available public information about the issuer.

 

 

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Portfolio could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

 

 

Because under normal circumstances the Portfolio invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in equity securities of foreign companies, the NAV of the Portfolio will change with changes in the share prices of the investment companies in which the Portfolio invests.

 

 

There is a risk that the Portfolio, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

 

 

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

The performance of the Portfolio will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

 

 

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. the Portfolio may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Cyber security risk is the risk of an unauthorized breach and access to Portfolio assets, Portfolio or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Portfolio investors from purchasing, redeeming or exchanging shares or receiving distributions. The Portfolio and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Portfolio or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio or its service providers may adversely impact and cause financial losses to the Portfolio or its shareholders. Issuers of securities in which the Portfolio invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Portfolio’s investment strategies and operations.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Portfolio pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in fixed income securities that the Portfolio’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of providing total return, or invest substantially all of their assets in such fixed income securities. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses.

 

Under normal market conditions, the Adviser expects substantially all of the Portfolio’s net assets to be invested in the securities of investment companies, including other investment companies funded by insurance company separate accounts, that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

 

One-Year Fixed Income Asset Class: The underlying investment companies generally will purchase U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the U.S., foreign government and agency obligations, bank obligations, including the obligations of U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements, and obligations of supranational organizations such as the World Bank, the European Investment Bank and the Inter-American Development Bank. Generally, obligations comprising this asset class will mature within one year from the date of settlement, but substantial investments may be made in obligations maturing within two years from the date of settlement when greater returns are available.

 

Two-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, and other debt obligations of domestic and foreign issuers with maturities of no more than two years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

 

Intermediate Government Fixed Income Asset Class: The underlying investment companies generally will purchase debt obligations of the U.S. government and U.S. government agencies. Generally, investment companies in the asset class will purchase securities with maturities of between five and fifteen years, however such investment companies ordinarily will have an average weighted maturity of between three and ten years. The underlying investment companies may invest a portion of their assets in the obligations of foreign governments. Those obligations at the time of purchase must be either rated in the highest rating category of a nationally recognized statistical rating organization or, in the case of any obligation that is unrated, of comparable quality.

 

Five-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. Generally, obligations comprising this asset class have a weighted average maturity not exceeding five years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

 

Short-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 1-5 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non- U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to one year and less than five years.

 

Intermediate-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 5-10 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non-U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to five years and less than ten years.

 

Inflation Protected Securities Asset Class: The underlying investment companies generally will track the investment results of the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L), which measures the performance of the inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.” TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation - a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index (“CPI”), and TIPS’ principal payments are adjusted according to changes in the CPI. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase.

 

The underlying investment companies may also use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to hedge currency exposure or to adjust market exposure based on actual or expected cash inflows or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

 

Certain underlying investment companies may concentrate their investments (invest more than 25% of its total assets) in obligations of U.S. and foreign banks and bank holding companies when the yield to maturity on eligible portfolio investments in banking securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange (“NYSE”) is open for trading. While the Portfolio will not concentrate its investments in any one industry, the Portfolio may be focused on banking sectors under certain circumstances.

 

The Portfolio reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Portfolio employs a temporary defensive measure, the Portfolio may not achieve its investment objective. Periodically the Adviser will review the allocations for the Portfolio in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Portfolio in the underlying investment companies without notice to shareholders or the holders of the variable annuity or variable life insurance policies.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Portfolio, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Portfolio or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Portfolio, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Fixed income securities in which the Portfolio’s underlying investment companies may invest are subject to certain risks, including: interest rate risk, reinvestment risk, prepayment and extension risk, credit/default risk, and the risks associated with investing in repurchase agreements.

 

 

Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes.

 

 

Reinvestment risk involves the risk that proceeds from matured investments may be re-invested at lower interest rates.

 

 

Prepayment risk involves the risk that in declining interest rates environments prepayments of principal could increase and require the Portfolio to reinvest proceeds of the prepayments at lower interest rates.

 

 

Extension risk involves the risk that prepayments of principal will decrease when interest rates rise resulting in a longer effective maturity of a security.

 

 

Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. Credit risk also involves the risk that the credit rating of a security may be lowered.

 

 

Repurchase agreement risk involves the risk that the other party to a repurchase agreement will be unable to complete the transaction and the underlying investment company in which the Portfolio invests may suffer a loss as a result.

 

 

Because the Portfolio owns shares of underlying investment companies that invest in foreign issuers, the Portfolio is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards. In addition, foreign securities in which the underlying investment companies invest may be listed on foreign exchanges that trade on weekends or other days when the underlying investment companies do not calculate their net asset value (“NAV”). As a result, the value of the underlying investment companies’ holdings, and therefore the Portfolio’s holdings, may change on days when shareholders are not able to purchase or redeem the Portfolio’s shares.

 

 

Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Portfolio invests are denominated will fluctuate daily. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Portfolio than if it had not engaged in these contracts.

 

 

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Portfolio could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

 

 

Because under normal circumstances the Portfolio invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in fixed income securities, the NAV of the Portfolio will change with changes in the share prices of the investment companies in which the Portfolio invests.

 

 

Not all obligations of U.S. government agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed only by the credit of the issuing agency or instrumentality. Accordingly, there may be some risk of default by the issuer in such cases.

 

 

There is a risk that the Portfolio, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

 

 

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

The performance of the Portfolio will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

 

 

Banks are very sensitive to changes in money market and general economic conditions. Adverse general economic conditions can cause financial difficulties for a bank’s borrowers and the borrowers’ failure to repay their loans can adversely affect the bank’s financial situation. Banks are subject to extensive regulation and decisions by regulators may limit the loans banks make and the interest rates and fees they charge, which could reduce bank profitability.

 

 

Inflation protected securities, such as TIPS, generally will fluctuate in response to changes in real interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. In addition, interest payments on inflation-protected securities will generally vary up or down along with the rate of inflation. Real interest rates are generally measured as a nominal interest less an inflation rate. As such, investors should be aware that an investment in TIPS over a particular timeframe may decrease in value even in an inflationary environment. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Because of their inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

 

 

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Portfolio may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Cyber security risk is the risk of an unauthorized breach and access to Portfolio assets, Portfolio or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Portfolio investors from purchasing, redeeming or exchanging shares or receiving distributions. The Portfolio and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Portfolio or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio or its service providers may adversely impact and cause financial losses to the Portfolio or its shareholders. Issuers of securities in which the Portfolio invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Portfolio’s investment strategies and operations.

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may qualify for sales charge discounts on Class A Shares if you invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional, in the section of this Prospectus entitled “Shareholder Information — Sales Charges” and in the section of the Fund’s Statement of Additional Information (“SAI”) entitled “Purchase and Redemption Information — Reducing or Eliminating the Front-End Sales Charge.” Additionally, you may be required to pay commissions and/or other forms of compensation to a broker for transactions in Class I Shares of the Fund, which are not reflected in the tables or the examples below.

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 91% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities, primarily common stocks, of companies within the Russell 1000® Index and S&P 500® Index. The Fund’s investments will generally consist of securities, which may include common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock. The Fund purchases equity securities traded in the U.S. on registered exchanges or the over-the-counter market. The Fund may also invest in other registered investment companies, including exchange-traded funds (“ETFs”).

 

Summit Global Investments, LLC (the “Adviser”) attempts to lower the Fund’s market risk by investing in U.S. equity securities that lower the overall volatility of the Fund’s portfolio as compared to the S&P 500® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. The Fund invests in stocks that often exhibit less volatile stock price patterns, strengthening business metrics (i.e., earnings, debt, return on assets, competition, customers, industry, etc.) and quantitative factors such as earnings variability, leverage, volatility, price/book, price/cash flow, etc. In addition, the Adviser reviews the idiosyncratic risks associated with each stock if these risks are deemed elevated with increased downside risks, due to environmental, social and/or governance (“ESG”) issues. The Adviser selects securities for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility.

 

The Fund may sell a stock if the Adviser identifies fundamental, ESG, or legal risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Common Stock Risk. Investments in common stocks are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited

 

ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that the Fund may apply in selecting securities. The Fund seeks to screen out companies that it believes may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. The Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

 

 

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. For the last fiscal year, the annual portfolio turnover rate of the Fund was lower than 100%, but the Fund’s portfolio turnover rate is expected to vary from year to year. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

 

 

Investment Companies and ETFs Risk. The Fund’s investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including 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. Certain ETFs maybe thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

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.

 

 

Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks’ price levels. Investing in low volatility stocks may limit the Fund’s gains in rising markets.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

 

 

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.

 

 

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

 

 

Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

Objective [Heading] rr_ObjectiveHeading Investment Objective
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock

The SGI U.S. Small Cap Equity Fund (for this section only, the “Fund”) seeks to outperform the Russell 2000® Index over a market cycle while reducing overall volatility. There can be no guarantee that the Fund will achieve its investment objective.

Expense [Heading] rr_ExpenseHeading Expenses and Fees
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may qualify for sales charge discounts on Class A Shares if you invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional, in the section of this Prospectus entitled “Shareholder Information — Sales Charges” and in the section of the Fund’s Statement of Additional Information (“SAI”) entitled “Purchase and Redemption Information — Reducing or Eliminating the Front-End Sales Charge.” Additionally, you may be required to pay commissions and/or other forms of compensation to a broker for transactions in Class I Shares of the Fund, which are not reflected in the tables or the examples below.

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 135% of the average value of its portfolio.

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 $10,000 in the Class A Shares or Class C Shares or $1,000,000 in the Class I Shares of the Fund and 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 [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities, primarily common stocks of U.S. issuers with small market capitalizations. A small market capitalization issuer generally is considered to be one whose market capitalization is, at the time the Fund makes the investment, similar to the market capitalization of companies in the Russell 2000® Index. The Russell 2000® Index is a small cap stock market index measuring the performance of approximately 2,000 small cap U.S. companies. As of May 7, 2021, the minimum market capitalization of the Russell 2000® Index was $257.1 million and the largest stock was $7.3 billion. The Fund’s investments will generally consist of securities, which may include common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock. The Fund purchases equity securities traded in the U.S. on registered exchanges or the over-the-counter market. The Fund may also invest in other registered investment companies, including exchange-traded funds (“ETFs”), and may invest in real estate investment trusts (“REITs”).

 

The Adviser attempts to lower the Fund’s market risk by investing in U.S. equity securities that lower the overall volatility of the Fund’s portfolio as compared to the Russell 2000® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. The Fund invests in stocks that often exhibit less volatile stock price patterns, strengthening business metrics (i.e., earnings, debt, return on assets, competition, customers, industry, etc.) and quantitative factors such as earnings variability, leverage, volatility, price/book, price/cash flow, etc. In addition, the Adviser reviews the idiosyncratic risks associated with each stock if these risks are deemed elevated with increased downside risks, due to environmental, social and/or governance (“ESG”) issues. The Adviser selects securities for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility.

 

The Fund may sell a stock if the Adviser identifies fundamental, ESG, or legal risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Common Stock Risk. Investments in common stocks are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations.

 

 

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

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that the Fund may apply in selecting securities. The Fund seeks to screen out companies that it believes may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. The Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

 

 

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

 

 

Investment Companies and ETFs Risk. The Fund’s investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including 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. Certain ETFs may be thinly traded and experience large spreads between the “ask” price

 

quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks’ price levels. Investing in low volatility stocks may limit the Fund’s gains in rising markets.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

 

 

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

 

 

REITs Risk. The Fund’s investments in REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidating interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the securities of larger companies. 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.

 

 

Small Cap Risk. Stocks of small companies may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

 

 

Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold, and sell Fund shares. You may qualify for sales charge discounts on Class A Shares if you invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional, in the section of this Prospectus entitled “Shareholder Information — Sales Charges” and in the section of the Fund’s Statement of Additional Information (“SAI”) entitled “Purchase and Redemption Information — Reducing or Eliminating the Front-End Sales Charge.” Additionally, you may be required to pay commissions and/or other forms of compensation to a broker for transactions in Class I Shares of the Fund, which are not reflected in the tables or the examples below.

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. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. Portfolio turnover may vary from year to year, as well as within a year. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 88% of the average value of its portfolio.

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 $1,000,000 in Class I Shares or $10,000 in Class A Shares or Class C Shares of the Fund for the time periods indicated and that you sell your shares at the end of those periods. The Example also assumes that each year your investment has a 5% return and Fund operating expenses remain the same.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of the value of its net assets, plus any borrowings for investment purposes, in equity securities. The Fund invests, under normal market conditions, significantly (ordinarily at least 40% - unless market conditions are not deemed favorable by the Adviser, in which case the Fund would invest at least 30%) in non-U.S. companies. The Fund defines non-U.S. companies as companies that (i) 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 derive a significant portion of their revenue or profits from businesses, investments or sales, outside of the United States.

 

The Fund’s investments in equity securities include, without limitation, common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock.The Fund’s investments will generally consist of securities, which may include common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock. The Fund purchases equity securities traded on registered exchanges or the over-the-counter market. The Fund may invest in securities of foreign issuers either directly or through depository receipts, including American Depository Receipts (“ADRs”). The Fund may also invest in other registered investment companies, including exchange-traded funds (“ETFs”). The Fund may invest in or have exposure to companies of any size, but primarily invests in large- and mid- capitalization companies.

 

The Adviser attempts to lower the Fund’s market risk by investing in equity securities that lower the overall volatility of the Fund’s portfolio as compared to global equity benchmarks. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. The Fund invests in stocks that exhibit less volatile stock price patterns, strengthening business metrics (i.e., earnings, debt, return on assets, competition, customers, industry, etc.) and quantitative factors such as earnings variability, leverage, volatility, price/book, price/cash flow, etc. In addition, the Adviser reviews the idiosyncratic risks associated with each stock if these risks are deemed elevated with increased downside risks, due to environmental, social and/or governance (“ESG”) issues. The Adviser selects

securities for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility.

 

The Fund may sell a stock if the Adviser identifies fundamental, ESG, or legal risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Common Stock Risk. Investments in common stocks are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that the Fund may apply in selecting securities. The Fund seeks to screen out companies that it believes may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. The Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain

 

countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its net asset value (“NAV”). As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. For the last fiscal year, the annual portfolio turnover rate of the Fund was lower than 100%, but the Fund’s portfolio turnover rate is expected to vary from year to year. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

 

 

Investment Companies and ETFs Risk. The Fund’s investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including 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. Certain ETFs maybe thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

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.

 

 

Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks’ price levels. Investing in low volatility stocks may limit the Fund’s gains in rising markets.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

 

 

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.

 

 

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

 

 

Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

Bar Chart and Performance Table [Heading] rr_BarChartAndPerformanceTableHeading Performance Information
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

Returns shown were generated under the management of the Fund’s former investment adviser and reflect a previous investment strategy. The Fund operated as a series of Scotia Institutional Funds prior to the close of business on March 21, 2014 (the “Predecessor Fund”). Before the Fund commenced operations, all of the assets and liabilities of the Predecessor Fund were transferred to the Fund in a tax-free reorganization (the “Reorganization”). The Reorganization occurred on March 21, 2014. As a result of the Reorganization, the Fund assumed the performance and accounting history of the Predecessor Fund prior to the date of the Reorganization. The performance shown for periods prior to March 21, 2014 is that of the Predecessor Fund.

 

The Board approved the Adviser to serve as the Global Equity Fund’s investment adviser effective January 1, 2017. Returns shown for periods prior to January 1, 2017 were generated under the management of the Global Equity Fund’s former investment adviser.

 

The chart below illustrates the performance of the Fund’s Class I Shares. Performance for Class A Shares and Class C Shares is not shown because Class A Shares and Class C Shares had not commenced operations prior to the date of this Prospectus. The information shows you how the Fund’s performance has varied year by year and provides some indication of the risks of investing in the Fund. The chart assumes reinvestment of dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results.

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 total annual fund operating expenses or in the Example, affect the Fund's performance. Portfolio turnover may vary from year to year, as well as within a year. During the most recent fiscal year, the Fund's portfolio turnover rate was 314% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by investing under normal circumstances at least 80% of the net assets of the portfolio (including borrowings for investment purposes) in the stocks of U.S. companies with market capitalizations, at the time of purchase, that are within the trailing twelve-month range of the market capitalizations of those companies that are included in the Russell 2000® Index (“Small Cap Stocks”). For purposes of this investment policy, stocks of U.S. companies are stocks that are listed on a securities exchange or market inside the United States. Because the Russell 2000® Index (“Index”) is modified (“reconstituted”) regularly (usually each year) to replace companies that no longer qualify for inclusion in the Index due to, among other reasons, having market capitalizations that have grown too large, the Adviser uses the trailing twelve-month range of market capitalizations to mitigate the need to trade stocks in the portfolio due to Index reconstitution. Further, the Adviser will not sell from the portfolio any holdings that the Adviser believes are likely to appreciate more than the Index solely because the market capitalizations of such holdings cause the portfolio to hold less than 80% of its net assets within this range. As such, the Fund may, from time to time, hold less than 80% of its net assets within this range. The Fund attempts to achieve its objective by taking long positions in Small Cap Stocks that the Adviser believes are undervalued given their future earnings growth prospects. As part of its investment strategy, the Adviser will continue to invest in Small Cap Stocks that the Adviser believes will appreciate more than the Index. Shareholders will be notified by the Fund sixty days in advance of any change in this 80% policy. In seeking to achieve its principal investment strategies, the Fund will engage in trading of portfolio securities that will likely result in a high portfolio turnover rate.

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund's principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.  Different risks may be more significant at different times depending on market conditions or other factors.

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

Environmental, Social and Governance (“ESG”) Investing Risk. ESG investing risk is the risk stemming from the ESG factors that the Fund may apply in selecting securities. The Fund seeks to screen out companies that it believes may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s returns may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. As a result, the Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

 

Equity Stock Risk. Common stocks may decline over short or even extended periods of time. Equity markets tend to be cyclical; there are times when stock prices generally increase, and other times when they generally decrease. Therefore, you could lose money by investing in the Fund.

 

Growth Stock Risk. Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund's return may be adversely affected during a market downtown and when growth stocks are out of favor.

 

Investment Companies and Exchange-Traded Funds (“ETFs”) Risk. The Fund's investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including 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 an ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. Certain ETFs may be thinly traded and experience large spreads between the "ask" price quoted by a seller and the "bid" price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF's shares could result in such shares trading at a significant premium or discount to their NAV.

 

Market Risk. The net asset value ("NAV") of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

 

Portfolio Turnover Risk. The Fund may frequently trade its portfolio holdings. High portfolio turnover will cause the Fund to incur higher brokerage commissions and other transaction costs, which could lower the Fund's performance. In addition to lower performance, high portfolio turnover could result in higher taxable capital gains. A portfolio turnover rate of 100% is considered to be high.

 

Small Cap Risk. The Fund will invest in Small Cap Stocks that may be more volatile than investments in issuers with larger market capitalizations. Issuers of Small Cap Stocks are not as diversified in their business activities as issuers with larger market capitalizations and are more susceptible to changes in the business cycle. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

 

Value Stock Risk. Although the Fund will invest in stocks that the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market turndown and when value stocks are out of favor.

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 178% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests in securities of affiliated and unaffiliated open-end mutual funds and exchange-traded funds (“ETFs”) (collectively, “Underlying Funds”). The Fund may allocate assets across six categories of Underlying Funds: domestic equities, foreign equities (including emerging markets securities), domestic investment-grade bonds, domestic high yield bonds (also known as “junk bonds”), foreign investment-grade and high yield bonds, and money market funds.

 

Under normal circumstances, the Fund will invest primarily in Underlying Funds focusing on domestic equities and large capitalization foreign equities, a lesser amount in Underlying Funds focused on small and mid-capitalization foreign equities and emerging markets, and a small amount in Underlying Funds focused on domestic investment-grade bonds, domestic high yield bonds, foreign investment-grade and high yield bonds, and money market funds.

 

Summit Global Investments, LLC (the “Adviser”) attempts to lower the Fund’s market risk by investing in Underlying Funds that seek to lower the overall volatility of the Fund’s portfolio as compared to the S&P 500® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In addition, the Adviser reviews the idiosyncratic risks associated with each Underlying Fund and if these risks are deemed elevated with increased downside risks the Adviser may make changes to the Underlying Funds. The Adviser selects Underlying Funds for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility.

 

Some Underlying Funds may have processes that include environmental, social, and/or governance (“ESG”) considerations as part of their investment strategy. Not all Underlying Funds will include ESG as part of their investment strategy.

 

The Adviser may evaluate how an Underlying Fund uses proxy votes and access to corporate management. This process may include interviews with an Underlying Fund’s management and an examination of an Underlying Fund’s proxy voting records, prospectus and other reports. The methods that Underlying Funds use may vary.

 

The Fund may focus its investments in a particular industry or sector for the purpose of capitalizing on performance momentum in that industry or sector due to significant changes in market conditions or geopolitical conditions.

 

The Fund may sell an Underlying Fund if the Adviser identifies fundamental, ESG, legal or other risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

 

 

Currency Risk. Underlying Funds that invest in foreign securities are subject to currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and that 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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective investment advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds, or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Dividend-Paying Securities Risk. Underlying Funds that invest in dividend-paying securities may be subject to the risk that the company issuing such securities may fail and have to decrease or eliminate its dividend. In such an event, an Underlying Fund, and in turn the Fund, may not only lose the dividend payout but the stock price of the company may fall.

 

 

Emerging Markets Risk: Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of 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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that some Underlying Funds may apply in selecting securities. Some Underlying Funds may screen out particular companies that do not meet their ESG criteria. This may affect the Underlying Funds’ and the Fund’s exposure to certain companies or industries and cause the Underlying Funds to forego certain investment opportunities. The Underlying Funds’ results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. Certain Underlying Funds may screen out companies that they believe may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. As a result, the Underlying Funds may invest in companies that do not reflect the beliefs and values of any particular investor.

 

 

Equity Risk. The Underlying Funds’ investments in common stock are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

 

 

Exchange-Traded Fund Risk. In addition to risks generally associated with investments in investment company securities, ETFs are subject to the following risks that do not apply to traditional mutual funds: (i) an ETF’s shares may trade at a market price that is above or below their net asset value (“NAV”); (ii) an active trading market for an ETF’s shares may not develop or be maintained; (iii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iv) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Fixed Income Securities Risk. To the extent the Fund invests in Underlying Funds that invest in fixed income securities, the Fund will be subject to fixed income securities risks. While fixed income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.

 

Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

 

Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.

 

Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.

 

Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.

 

Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.

 

Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

 

 

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. Underlying Funds that invest in foreign securities may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Investments in emerging market securities by Underlying Funds are subject to higher risks than those in developed countries because there is greater uncertainty in less established markets and economies.

 

 

Growth Risk. If an Underlying Fund adviser’s perceptions of a company’s growth potential are wrong, the securities purchased by that Underlying Fund may not perform as expected, thereby reducing the Underlying Fund’s and the Fund’s return.

 

 

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

 

 

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

 

 

Index Management Risk. To the extent the Fund invests in an Underlying Fund that is intended to track a target index, it is subject to the risk that the Underlying Fund may track its target index less closely. For example, an adviser to the Underlying Fund may select securities that are not fully representative of the index, and the Underlying Fund’s transaction expenses, and the size and timing of its cash flows, may result in the Underlying Fund’s performance being different than that of its index. Additionally, the Underlying Fund will generally reflect the performance of its target index even when the index does not perform well.

 

 

Industry or Sector Focus Risk. To the extent the Fund invests in Underlying Funds that focus their investments in a particular industry or sector, the Fund’s shares may be more volatile and fluctuate more than shares of a fund investing in a broader range of securities.

 

 

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

 

 

Low Volatility Risk. Underlying Funds with investments in low volatility companies are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility Underlying Funds may not produce investment exposure that has lower variability to changes in market levels. Investing in low volatility Underlying Funds may limit the Fund’s gains in rising markets.

 

 

Management Risk. The Fund is subject to the risk of poor selection in Underlying Funds. The Underlying Funds may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in Underlying Funds that the Adviser believes will produce less volatility, there is no guarantee that the Underlying Funds will perform as expected. The prices of securities held by the Underlying Funds may decline in response to conditions affecting the general economy, overall market changes, local, regional or global political, social or economic instability, and currency, interest rate and commodity price fluctuations.

 

 

Mid-Capitalization Companies Risk. The stocks of mid-capitalization companies that the Underlying Funds may invest in 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 a limited 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.

 

 

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

 

 

Small-Capitalization Companies Risk. Small-cap companies that the Underlying Funds may invest in may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small-cap company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

 

 

Underlying Funds Risk. Investing in Underlying Funds may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The Fund’s investment performance and its ability to achieve its investment objective are directly related to the performance of the Underlying Funds in which it invests. The risk of owning an Underlying Fund generally reflects the risks of owning the underlying investments the Underlying Fund holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 170% of the average value of its portfolio.

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 $10,000 in Class I Shares of 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.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests in securities of affiliated and unaffiliated open-end mutual funds and exchange-traded funds (“ETFs”) (collectively, “Underlying Funds”). The Fund may allocate assets across six categories of Underlying Funds: domestic equities, foreign equities (including emerging markets securities), domestic investment-grade bonds, domestic high yield bonds (also known as “junk bonds”), foreign investment-grade and high yield bonds, and money market funds.

 

Under normal circumstances, the Fund will invest primarily in Underlying Funds focused on domestic equities, a lesser amount in Underlying Funds focused on large capitalization foreign equities, mid-capitalization foreign equities, emerging markets and domestic investment-grade bonds, and a small amount in Underlying Funds focused on small-capitalization foreign equities, domestic high yield bonds, foreign investment-grade and high yield bonds, and money market funds.

 

Summit Global Investments, LLC (the “Adviser”) attempts to lower the Fund’s market risk by investing in Underlying Funds that seek to lower the overall volatility of the Fund’s portfolio. The Fund seeks volatility between 60%-80% as compared to the S&P 500® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In addition, the Adviser reviews the idiosyncratic risks associated with each Underlying Fund and if these risks are deemed elevated with increased downside risks the Adviser may make changes to the Underlying Funds. The Adviser selects Underlying Funds for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of higher volatility.

 

Some Underlying Funds may have processes that include environmental, social, and/or governance (“ESG”) considerations as part of their investment strategy. Not all Underlying Funds will include ESG as part of their investment strategy.

 

The Adviser may evaluate how an Underlying Fund uses proxy votes and access to corporate management. This process may include interviews with an Underlying Fund’s management and an examination of an Underlying Fund’s proxy voting records, prospectus and other reports. The methods that Underlying Funds use may vary.

 

The Fund may focus its investments in a particular industry or sector for the purpose of capitalizing on performance momentum in that industry or sector due to significant changes in market conditions or geopolitical conditions.

 

The Fund may sell an Underlying Fund if the Adviser identifies fundamental, ESG, legal or other risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

 

 

Currency Risk. Underlying Funds that invest in foreign securities are subject to currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and that 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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective investment advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds, or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Dividend-Paying Securities Risk. Underlying Funds that invest in dividend-paying securities may be subject to the risk that the company issuing such securities may fail and have to decrease or eliminate its dividend. In such an event, an Underlying Fund, and in turn the Fund, may not only lose the dividend payout but the stock price of the company may fall.

 

 

Emerging Markets Risk: Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of 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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that some Underlying Funds may apply in selecting securities. Some Underlying Funds may screen out particular companies that do not meet their ESG criteria. This may affect the Underlying Funds’ and the Fund’s exposure to certain companies or industries and cause the Underlying Funds to forego certain investment opportunities. The Underlying Funds’ results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. Certain Underlying Funds may screen out companies that they believe may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. As a result, the Underlying Funds may invest in companies that do not reflect the beliefs and values of any particular investor.

 

 

Equity Risk. The Underlying Funds’ investments in common stock are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

 

 

Exchange-Traded Fund Risk. In addition to risks generally associated with investments in investment company securities, ETFs are subject to the following risks that do not apply to traditional mutual funds: (i) an ETF’s shares may trade at a market price that is above or below their net asset value (“NAV”); (ii) an active trading market for an ETF’s shares may not develop or be maintained; (iii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iv) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

 

 

Fixed Income Securities Risk. To the extent the Fund invests in Underlying Funds that invest in fixed income securities, the Fund will be subject to fixed income securities risks. While fixed income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.

 

Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

 

Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.

 

Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.

 

Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.

 

Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.

 

Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

 

 

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. Underlying Funds that invest in foreign securities may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Investments in emerging market securities by Underlying Funds are subject to higher risks than those in developed countries because there is greater uncertainty in less established markets and economies.

 

 

Growth Risk. If an Underlying Fund adviser’s perceptions of a company’s growth potential are wrong, the securities purchased by that Underlying Fund may not perform as expected, thereby reducing the Underlying Fund’s and the Fund’s return.

 

 

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

 

 

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

 

 

Index Management Risk. To the extent the Fund invests in an Underlying Fund that is intended to track a target index, it is subject to the risk that the Underlying Fund may track its target index less closely. For example, an adviser to the Underlying Fund may select securities that are not fully representative of the index, and the Underlying Fund’s transaction expenses, and the size and timing of its cash flows, may result in the Underlying Fund’s performance being different than that of its index. Additionally, the Underlying Fund will generally reflect the performance of its target index even when the index does not perform well.

 

 

Industry or Sector Focus Risk. To the extent the Fund invests in Underlying Funds that focus their investments in a particular industry or sector, the Fund’s shares may be more volatile and fluctuate more than shares of a fund investing in a broader range of securities.

 

 

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

 

 

Low Volatility Risk. Underlying Funds with investments in low volatility companies are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility Underlying Funds may not produce investment exposure that has lower variability to changes in market levels. Investing in low volatility Underlying Funds may limit the Fund’s gains in rising markets.

 

 

Management Risk. The Fund is subject to the risk of poor selection in Underlying Funds. The Underlying Funds may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in Underlying Funds that the Adviser believes will produce less volatility, there is no guarantee that the Underlying Funds will perform as expected. The prices of securities held by the Underlying Funds may decline in response to conditions affecting the general economy, overall market changes, local, regional or global political, social or economic instability, and currency, interest rate and commodity price fluctuations.

 

 

Mid-Capitalization Companies Risk. The stocks of mid-capitalization companies that the Underlying Funds may invest in 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 a limited 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.

 

 

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

 

 

Small-Capitalization Companies Risk. Small-cap companies that the Underlying Funds may invest in may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small-cap company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

 

 

Underlying Funds Risk. Investing in Underlying Funds may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The Fund’s investment performance and its ability to achieve its investment objective are directly related to the performance of the Underlying Funds in which it invests. The risk of owning an Underlying Fund generally reflects the risks of owning the underlying investments the Underlying Fund holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund was 33% of the average value of its portfolio.

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 [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in a diversified portfolio consisting primarily of equity securities, such as common stocks of issuers across the capitalization spectrum and identified by the Adviser as having value characteristics.

 

The Adviser examines various factors in determining the value characteristics of such issuers including price to book value ratios and price to earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, such as return on equity and earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

The Fund may also invest up to 20% of its total assets in non U.S. dollar-denominated securities.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

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 invest up to 10% of its net assets in securities that can be converted into common stock, such as certain debt securities and preferred stock.

 

The Fund may hedge overall portfolio exposure up to 40% of its net assets through the purchase and sale of index and individual put and call options.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

 

 

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.

 

 

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 Adviser is incorrect in its expectation of price fluctuations.

 

 

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.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in a diversified portfolio consisting primarily of equity securities, such as common stocks of issuers with small market capitalizations and identified by the Adviser as having value characteristics. A small market capitalization issuer generally is considered to be one whose market capitalization is, at the time the Fund makes the investment, similar to the market capitalization of companies in the Russell 2000® Value Index. The Russell 2000® Value Index is an unmanaged index that contains stocks from the Russell 2000® Index with less than average growth orientation. As of November 30, 2021, the median market capitalization of the Russell 2000® Value Index was $1.0 billion and the largest stock was $18.3 billion. Please note that this range is as of a particular point in time and is subject to change.

 

The Fund generally invests in the equity securities of small companies. The Adviser will seek to invest in companies it considers to be well managed and to have attractive fundamental financial characteristics. The Adviser believes greater potential for price appreciation exists among small companies since they tend to be less widely followed by other securities analysts and thus may be more likely to be undervalued by the market. The Fund may invest from time to time a portion of its assets, not to exceed 20% (under normal conditions) at the time of purchase, in companies with larger market capitalizations.

 

The Adviser examines various factors in determining the value characteristics of such issuers including price to book value ratios and price to earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

The Fund may also invest up to 25% of its total assets in non U.S. dollar-denominated securities.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

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.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Small Cap Companies Risk. The Fund will invest in smaller issuers which are more volatile and less liquid than investments in issuers with a market capitalization greater than the market capitalization of companies in the Russell 2000® Value Index. Small market capitalization issuers are not as diversified in their business activities as issuers with market capitalizations greater than the market capitalization of companies in the Russell 2000® Value Index and are more susceptible to changes in the business cycle.

 

 

The small capitalization equity securities in which the Fund invests may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

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 Total annual Fund operating expenses or in the Example, affect the Fund's performance. The Fund does not have any portfolio turnover information as the Fund had not commenced operations prior to the date of this Prospectus.

Expense Example Narrative [Text Block] 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 [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in equity securities of U.S. companies that, at the time of purchase, have a market capitalization that is within the range of the market capitalization of issuers in the Russell 2000 Small Cap Value Index. As of November 30, 2021, the median market capitalization of the companies in the Russell 2000 Small Cap Value Index is $1.0 billion and the largest stock is $17.4 billion. The Fund may invest in depositary receipts and equity securities of foreign companies. Although the Fund invests primarily in common stocks (which include both exchange-listed and over-the-counter ("OTC") securities), the Fund may invest in all types of equity and equity-related securities, including (without limitation):

 

Securities convertible into common stocks.
Shares of real estate investment trusts ("REITs").
Warrants and rights to purchase common stocks.
Preferred stocks.
Exchange-traded limited partnerships.

Special Situations: The Fund may invest in companies that may experience unusual and possibly unique developments which may create a special opportunity for significant returns. Special situations include: significant technological improvements or important discoveries; reorganizations, recapitalizations or mergers; favorable resolutions of litigation; new management or material changes in company policies; and actual or potential changes in control of a company.

 

Strategies: The Adviser uses a value approach to select the Fund's investments. Using this investment style, the Adviser seeks securities selling at substantial discounts to their underlying values and then holds these securities until the market values reflect what the Adviser believes to be their intrinsic values. The Adviser employs a bottom-up strategy, focusing on undervalued industries that the Adviser believes are experiencing positive change. The Adviser then uses both qualitative and quantitative methods to assess a security's potential value. The portfolio manager managing the Fund and the analytical team meet with a multitude of companies annually to identify companies with increasing returns on capital in their core businesses which are selling at attractive valuations.

 

Factors the Adviser looks for in selecting investments include (without limitation):

Increasing returns on invested capital.
Companies who have demonstrated an ability to generate high return on invested capital.
Companies which provide solid cash flows with appropriate capital.
Potential catalysts such as new products, cyclical upturns and changes in management.

Low market valuations relative to earnings forecast, book value, cash flow and sales.

The Fund is non-diversified and may invest in fewer securities at any one time than a diversified fund.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in equity securities of U.S. companies that, at the time of purchase, have a market capitalization that is within the range of the market capitalization of issuers in the Russell 2000 Small Cap Value Index.
Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund's principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

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.
Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.
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.
Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy.
Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund's holdings may change on days when shareholders are not able to purchase or redeem the Fund's shares.

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund's portfolio management practices do not work to achieve their desired result.
Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.
New Fund Risk. The Fund is a recently organized, diversified management investment company with a limited operating history. In addition, there can be no assurance that the Fund will grow to, or maintain, an economically viable size, in which case the Board of the Company 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.
OTC Risk. Securities traded on OTC markets are not listed and traded on an organized exchange such as the New York Stock Exchange ("NYSE"). Generally, the volume of trading in an unlisted or OTC common stock is less than the volume of trading in an exchange-listed stock. As a result, the market liquidity of some stocks in which the Fund invests may not be as great as that of exchange-listed stocks and, if the Fund were to dispose of such stocks, the Fund may have to offer the shares at a discount from recent prices or sell the shares in small lots over an extended period of time. In addition, penny stocks and pink sheet stocks can be classified as OTC stocks.
REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the Investment Company Act of 1940, as amended.
Rights and Warrants Risk. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not executed prior to the right's or warrant's expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security.
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.

Special Situations Risk. The Fund will seek to benefit from "special situations," such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the "special situation" might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer's securities and fail to produce gains or produce a loss for the Fund.

Risk Lose Money [Text] rr_RiskLoseMoney You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus 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.

Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”).

As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the price of these stocks will not move even lower.

 

 

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

Rights and Warrants Risk. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not executed prior to the right’s or warrant’s expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

 

 

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.

 

 

Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

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 Total annual Fund operating expenses or in the Example, affect the Fund's performance.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, in a 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 without limitation 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 participation. 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 Adviser, 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. The Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries).

Under normal circumstances, the Fund will invest at least 80% of its net assets, including borrowings for investment purposes, in companies that meet the Adviser’s sustainability criteria. Fund holdings must have received at least a “satisfactory” sustainability rating by the Adviser’s Sustainability and Engagement Team (the “Sustainability Team”) based on the Sustainability Team’s written research analysis. The Sustainability Team assesses each holding as either “excellent,” “good,” “satisfactory,” or “poor.” An issuer will be rated “excellent” if the issuer, in the opinion of the Sustainability Team, has a well-developed sustainability structure, well-designed goals for the future, demonstrated successful implementation of its sustainability program and shareholder friendly corporate governance. The Sustainability Team will rate an issuer as “good” if the issuer, in the opinion of the Sustainability Team, has attributes similar to those described in “excellent” but has some deficiencies that warrant improvement. The Sustainability Team will rate an issuer as “satisfactory” if the issuer, in the opinion of the Sustainability Team, has a sustainability program in place, has a sufficient level of sustainability disclosure for the Sustainability Team to assess the issuer’s sustainability program and has a commitment to improve its sustainability program and disclosure in the near term. All other holdings assessed by the Sustainability Team that are not rated either “excellent”, “good” or “satisfactory” are rated “poor”. These ratings are subjective and may vary if the issuer has products or services that inherently promote sustainability, particularly for other products or services, or has engaged in conduct that has or has the potential to lower the sustainability reputation of the issuer in the opinion of the Sustainability Team.

The Sustainability Team uses a positive screen to identify issuers it considers to have characteristics that meet the Adviser’s sustainability criteria. The Sustainability Team assesses the sustainability of the issuer’s products, services and operations through original research and focusing on key areas such as corporate governance, internal sustainability structure, workforce and management diversity, training and employee development opportunities, safety programs and injury metrics, environmental effects such as goals and metrics for greenhouse gas emissions, energy usage, renewable energy, waste and water, supplier oversight and litigation and regulatory issues. The Sustainability Team uses primarily issuer published documents such as its sustainability report, website, publicly available financial reports such as the issuer’s 10-K and the issuer’s proxy statement to prepare the Sustainability Team’s research. The Sustainability Team also undertakes an internet search for any litigation, regulatory or reputational issues. The Sustainability Team may use third party research about industry trends for background information, but it does not rely on third party data about the issuer for its assessment of the issuer. The Sustainability Team provides a sustainability assessment for all issuers held in the Fund’s portfolio. The Sustainability Team’s ratings are subjective. No industries are automatically excluded from consideration. The Adviser will vote all securities for which it has voting authority in the best interests of its clients. The Adviser’s Governance Committee votes all proxies. The Governance Committee assesses the likely effect of the proxy proposal on the value of the issuer’s stock including the effect on the management of the issuer, the importance to shareholders of the proxy proposal and the cost of the proposal.

The Sustainability Team also engages with issuers regarding sustainability deficiencies and reviews any improvements by issuers annually.

The Fund generally invests in the equity securities of issuers believed by the Adviser to be undervalued in the marketplace, focusing on issuers that combine attractive valuations with catalysts for change. The Adviser 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 Adviser 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 Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals, business momentum, or sustainability practices of a specific investment or industry. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

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 invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

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.

While the Adviser intends to fully invest the Fund's assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund's principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

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.
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.
Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.
Derivatives Risk. The Fund's investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.
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. The information available of an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.
Exchange-Traded Fund Risk. ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund's own expenses. Certain ETFs may be thinly traded and experience large spreads between the "ask" price quoted by a seller and the "bid" price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

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.
Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.
Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. 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. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund's holdings may change on days when shareholders are not able to purchase or redeem the Fund's shares.
Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund's ability to buy or sell such securities.
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 Adviser 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.
Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund's portfolio management practices do not work to achieve their desired result.
Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.
Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.
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 a recently organized, diversified management investment company with a limited operating history. In addition, there can be no assurance that the Fund will grow to, or maintain, an economically viable size, in which case the Board of the Company may determine to liquidate 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 Adviser is incorrect in its expectation of price fluctuations.
REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the Investment Company Act of 1940, as amended.

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.
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.
Sustainable Investment Risk. The sustainability criterion required for Fund investment may cause the Fund to not invest in certain industries or issuers. As a result, the Fund may be overweight or underweight in certain industries or issuers relative to its benchmark index, which may cause the Fund’s performance to be more or less sensitive to developments affecting those industries or issuers. Sustainability information provided by issuers, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing issuers to engage in sustainable practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. There is no guarantee that sustainable investments will outperform the broader market on either an absolute or relative basis.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its 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 without limitation 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 participation. 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 Adviser, 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 the Adviser to be undervalued in the marketplace, focusing on issuers that combine attractive valuations with catalysts for change.

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

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 invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

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.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. 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. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

 

 

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.

 

 

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 Adviser is incorrect in its expectation of price fluctuations.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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.

 

 

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.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund will pursue its objective through a value oriented, research-driven strategy of investing in equity securities and financial instruments with equity like characteristics designed to provide exposure to emerging markets. Securities are selected by the Adviser using its “three circles” approach which combines a quantitative screening with a fundamental bottom up selection process. This investment strategy is grounded in the following principles: (1) low valuation stocks outperform high valuation stocks; (2) companies with strong fundamentals, e.g. high and sustainable returns on invested capital, outperform companies with weak fundamentals; and (3) stocks with positive business momentum, e.g. rising earnings estimates, outperform stocks with negative business momentum. The Adviser examines various factors in determining the value characteristics of issuers, including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, such as return-on-equity and earnings growth and cash flow.

 

The Fund intends, under normal circumstances, to invest at least 80% of its net assets (including borrowings for investment purposes) in the securities of emerging market issuers, related derivative instruments and other investments that are tied economically to emerging market countries. The Adviser considers an emerging market country to include any country that is: 1) generally recognized to be an emerging market country by the international financial community, including the World Bank; 2) classified by the United Nations as a developing country; or 3) included in the MSCI Emerging Markets Index. Due to the unique relationship between China and its separately administered regions, the Adviser includes Hong Kong and Macau as emerging markets, independent of above definitions 1 through 3. The Adviser determines that an investment is tied economically to an emerging market if such investment satisfies one or more of the following conditions: 1) the issuer’s primary trading market is in an emerging market; 2) the issuer is organized under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in emerging markets; 3) the investment is included in an index representative of emerging markets; and 4) the investment is exposed to the economic risks and returns of emerging markets.

 

In managing the Fund’s portfolio, the Adviser will seek to identify mispriced publicly traded equity securities of emerging market companies and purchase securities that the Adviser believes will outperform, emphasizing low valuation, positive business momentum and high quality.

 

The Fund’s portfolio is rebalanced regularly to maintain the optimal risk/return trade-off. The Adviser assesses each stock’s changing characteristics relative to its contribution to portfolio risk. The Adviser will sell a stock that the Adviser believes no longer offers an appropriate return-to-risk tradeoff. The Fund’s investment adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

 

The equity securities in which the Fund will invest, which may include equity securities of non-U.S. issuers that are traded in the markets of the United States, include equity securities issued by large-, mid- and small- or micro-cap companies, as well as exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, 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 may invest in securities of companies operating for three years or less (“unseasoned issuers”).

 

The Fund may invest up to 20% of its net assets in high yield debt obligations (commonly known as “junk bonds”), such as bonds and debentures, used by corporations and other business organizations (e.g. trusts or limited liability companies). Such high yield debt obligations are not considered to be investment grade. Junk bonds are rated BB or lower by S&P Global, or have a comparable rating by another nationally recognized statistical rating organization (or, if unrated are determined by the Adviser to be of comparable quality at the time of investment). The Fund may invest in securities of the lowest rating category, including securities in default. The Adviser may, but is not required to, sell a bond or note held by the Fund in the event that its credit rating is downgraded. The Fund will primarily invest in fixed income instruments, including high yield debt obligations, when the Fund believes that such instruments offer a better risk/reward profile than comparable equity opportunities.

 

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

In general, the Fund’s investments will be spread over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

 

The Fund may participate as a purchaser in initial public offerings of securities (“IPOs”). An IPO is a company’s first offering of stock to the public.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

The Fund may also seek to increase its income by lending portfolio securities.

 

The Fund will invest in derivatives, including put and call options, futures, contracts for differences, forward contracts and swaps, in lieu of investing directly in a security, currency or instrument, for hedging and non-hedging purposes. Contracts for differences offer exposure to price changes in an underlying security without ownership of such security, typically by providing investors the ability to trade on margin. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

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.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in Junk Bonds, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such Junk Bonds are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser 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.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund makes may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

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.

 

 

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

 

 

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 Adviser is incorrect in its expectation of price fluctuations. Losses incurred by the Fund in writing options can be potentially unlimited.

 

 

Portfolio Turnover Risk. The Fund may frequently trade its portfolio securities, resulting in higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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.

 

 

Segregated Account Risk. The Fund’s transactions in derivative instruments may require the Fund to establish a segregated account consisting of cash or liquid securities in an amount sufficient to cover the transactions. A security held in a segregated account cannot be sold while the position it is covering is outstanding, unless it is replaced with a similar security. As a result, there is a possibility that segregation of a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

 

 

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.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund was 31% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales will be invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage. The Fund invests, both long and short, in securities principally traded in the United States markets. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Adviser will determine the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Fund seeks to construct a portfolio that has less volatility than the United States equity market generally. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Fund intends, under normal circumstances, to invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities. Under normal circumstances, the Adviser expects that the Fund’s long positions will not exceed approximately 125% of the Fund’s net assets.

 

The Fund’s long and short positions may involve (without limit) equity securities of foreign issuers that are traded in the markets of the United States. The Fund may also invest up to 20% of its total assets directly in equity securities of foreign issuers.

 

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

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 invest from time to time a significant portion of its assets in smaller issuers which are more volatile and less liquid than investments in issuers with larger market capitalizations.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry.

 

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by corporations and other business organizations. High yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investmetns 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the Adviser may not be successful in its strategy of taking long positions in stocks the manager believes to be undervalued and short positions in stocks the manager believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio may make.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

Segregated Account Risk. A security held in a segregated account cannot be sold while the position it is covering is outstanding, unless it is replaced with a similar security. As a result, there is a possibility that segregation of a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

 

 

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises.

 

 

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

The table below compares the average annual total returns for the Fund’s Institutional Class both before and after taxes for the past calendar year, past five calendar years and past ten calendar years to the average annual total returns of a broad-based securities market index for the same periods. Although the Fund compares its average total return to a broad-based securities market index, the Fund seeks returns that are not correlated to securities market returns. The Fund seeks to achieve a 12-15% return over a full market cycle; however, there can be no guarantee that such returns will be achieved.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund was 61% of the average value of its portfolio.

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 [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund uses a hedged strategy. The Fund actively invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales (i.e. sales of securities the Fund does not own) are invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage.

 

The Fund invests, both long and short, in equity securities issued by large-, mid- and small (or “micro”) cap companies, as well as other instruments that are convertible into equity securities. Selling securities short is a form of leverage. Equity securities in which the Fund may invest include exchange-traded and over-the-counter common and preferred stocks, warrants, rights, convertible securities, depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies and 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 may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Fund may also invest in depositary receipts and equity securities of foreign companies (denominated in either U.S. dollars or foreign currencies), put and call options, futures, indexed securities and fixed-income securities (including bonds, notes, asset-backed securities, convertible securities, Eurodollar and Yankee dollar instruments, preferred stocks and money market instruments) and high yield securities (commonly referred to as “junk bonds”). Fixed income securities in which the Fund invests include those rated between AAA and D by a nationally recognized statistical rating organization, or deemed of comparable quality by the Adviser. The Adviser may also temporarily invest uninvested cash in money market funds and similar collective investment vehicles. The Fund may also seek to increase its income by lending portfolio securities.

 

The Adviser determines the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Fund seeks to construct a portfolio that has less volatility than the U.S. equity market by investing less than 100% of its assets in net long positions. Selection of individual securities to be held long or sold short will be based on a mix of quantitative techniques and fundamental security analysis. The Adviser selects stocks on the basis of three criteria: value, fundamental business strength and momentum. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

Although the Fund seeks to follow a hedged strategy, there can be no assurance that the Fund’s portfolio or investments will be insulated from market moves or effectively hedged against risk.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

The principal derivative instruments in which the Fund invests are futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations (of any rating, including defaulted securities and unrated securities), including bonds and debentures, issued by corporations and business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

Indexed Securities Risk. The Fund may invest in indexed securities whose value is linked to securities indices. Most such securities have values that rise and fall according to the change in one or more specified indices and may have characteristics similar to direct investments in the underlying securities. Depending on the index, such securities may have greater volatility than the market as a whole.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. The Adviser may be incorrect in the stocks it buys and believes to be undervalued and in stocks it sells short and believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the price of these stocks will not move even lower.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 300%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; the additional costs that may be incurred; and the potential loss of investment flexibility caused by the Fund’s obligations to provide collateral to the lender and set aside assets to cover the open position. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.

 

 

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

The Fund invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales will be invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage. The Fund invests, both long and short, in securities issued by U.S. and non-U.S. companies of any capitalization size.

 

With a long position, the Fund purchases a stock outright; with a short position, the Fund sells a security that it does not own and must borrow to meet its settlement obligations. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Adviser will determine the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, including return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Fund may invest in all types of equity and equity-related securities, including without limitation exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies (including exchanged-traded funds (“ETFs”)), real estate investment trusts (“REITs”) and equity participation. 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 Adviser, 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’s portfolio is rebalanced regularly. The Adviser assesses each investment’s changing characteristics relative to its contribution to portfolio risk. The Adviser will sell an investment held long or close out a short position that the Adviser believes no longer offers an appropriate return-to-risk tradeoff.

 

Under normal circumstances, the Adviser expects to sell securities short so that the Fund’s portfolio is approximately 50% net long with an average of between 30% and 70% net long.

 

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

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 invest from time to time a significant portion of its assets in smaller issuers which are more volatile and less liquid than investments in issuers with larger market capitalizations.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry. The Fund is non-diversified, and may invest in fewer securities at any one time than a diversified fund.

 

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by U.S. and foreign corporations and other business organizations (e.g. trusts or limited liability companies). Such high yield debt obligations are not considered to be investment grade. Non-investment grade fixed income securities (commonly known as “junk bonds”) are rated BB or lower by S&P Global, or have a comparable rating by another nationally recognized statistical rating organization (or, if unrated are determined by the Adviser to be of comparable quality at the time of investment). The Fund may invest in securities of the lowest rating category, including securities in default. The Adviser may, but is not required to, sell a bond or note held by the Fund in the event that its credit rating is downgraded.

 

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.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. 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. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the Adviser may not be successful in its strategy of taking long positions in stocks the manager believes to be undervalued and short positions in stocks the manager believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio may make.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

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 Adviser is incorrect in its expectation of price fluctuations. Losses incurred by the Fund in writing options can be potentially unlimited.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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.

 

 

Segregated Account Risk. A security held in a segregated account cannot be sold while the position it is covering is outstanding, unless it is replaced with a similar security. As a result, there is a possibility that segregation of a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

 

 

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; the additional costs that may be incurred; and the potential loss of investment flexibility caused by the Fund’s obligations to provide collateral to the lender and set aside assets to cover the open position. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited. The use of short sales may cause the Fund to have higher expenses than those of other equity mutual funds because of higher transaction costs, premiums, interest or dividends payable to the lender.

 

 

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund will pursue its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in equity and equity-related securities. The Fund will invest in a non-diversified, multi-strategy long-short portfolio of equity securities and financial investments with equity like characteristics designed to provide exposure to emerging markets. Securities are selected by the Adviser using its “three circles” approach which combines a quantitative screening with a fundamental bottom up selection process. This investment strategy is grounded in the following principles: (1) low valuation stocks outperform high valuation stocks; (2) companies with strong fundamentals, e.g. high and sustainable returns on invested capital, outperform companies with weak fundamentals; and (3) stocks with positive business momentum, e.g. rising earnings estimates, outperform stocks with negative business momentum. With a long position, the Fund purchases a stock outright; with a short position, the Fund sells a security that it does not own and must borrow to meet its settlement obligations. The Adviser examines various factors in determining the value characteristics of issuers, including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, such as return-on-equity and earnings growth and cash flow.

 

The Fund intends, under normal circumstances, to invest at least 80% of its net assets (including borrowings for investment purposes) in the securities of emerging market issuers, related derivative instruments and other investments that are tied economically to emerging market countries. The Adviser considers an emerging market country to include any country that is: 1) generally recognized to be an emerging market country by the international financial community, including the World Bank; 2) classified by the United Nations as a developing country; or 3) included in the MSCI Emerging Markets Index. Due to the unique relationship between China and its separately administered regions, the Adviser includes Hong Kong and Macau as emerging markets, independent of above definitions 1 through 3. The Adviser determines that an investment is tied economically to an emerging market if such investment satisfies one or more of the following conditions: 1) the issuer’s primary trading market is in an emerging market; 2) the issuer is organized under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in emerging markets; 3) the investment is included in an index representative of emerging markets; and 4) the investment is exposed to the economic risks and returns of emerging markets.

 

In managing the Fund’s portfolio, the Adviser will seek to identify mispriced publicly traded equity securities of emerging market companies including shorting securities that the Adviser believes will underperform and purchasing securities that the Adviser believes will outperform.

 

The long portion of the portfolio will emphasize low valuation, positive business momentum and high quality securities. The short portfolio will emphasize securities with high valuation risk, high balance sheet risk and signs of slowing sales and earnings momentum.

 

The Fund’s portfolio is rebalanced regularly to maintain the optimal risk/return trade-off. The Adviser assesses each stock’s changing characteristics relative to its contribution to portfolio risk. The Adviser will sell a stock held long or close out a short position in a stock that the Adviser believes no longer offers an appropriate return-to-risk tradeoff.

 

The equity securities in which the Fund will invest include equity securities issued by large-, mid- and small- or micro-cap companies, as well as exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, 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 may invest in securities of companies operating for three years or less (“unseasoned issuers”).

 

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by corporations and other business organizations (e.g. trusts or limited liability companies). Such high yield debt obligations are not considered to be investment grade. Non-investment grade fixed income securities (commonly known as “junk bonds”) are rated BB or lower by S&P Global, or have a comparable rating by another nationally recognized statistical rating organization (or, if unrated are determined by the Adviser to be of comparable quality at the time of investment). The Fund may invest in securities of the lowest rating category, including securities in default. The Adviser may, but is not required to, sell a bond or note held by the Fund in the event that its credit rating is downgraded. The Fund will primarily invest in fixed income instruments, including high yield fixed income obligations, when the Fund believes that such instruments offer a better risk/reward profile than comparable equity opportunities.

 

Under normal circumstances, the Adviser expects that the Fund’s long positions will not exceed approximately 50% of the Fund’s net assets with a typical range of 30% to 70% net long.

 

The Fund’s long and short positions may involve (without limit) equity securities of non-U.S. issuers that are traded in the markets of the United States.

 

In addition to the short sales discussed above, the Fund may make short sales “against the box,” a transaction in which the Fund enters into a short sale of a security which the Fund owns. The proceeds of the short sale will be held by a broker until the settlement date at which time the Fund delivers the security to close the short position. The Fund receives the net proceeds from the short sale. It is currently expected that the majority of the Fund’s short sales will not be against the box.

 

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

 

The Fund is the sole shareholder of Boston Partners Emerging Markets Long/Short Offshore Ltd., a wholly-owned subsidiary organized under the laws of the Cayman Islands (the “Subsidiary”). Generally, the Subsidiary invests primarily in futures contracts traded on Indian stock exchanges. The Fund and its Subsidiary comply with the same fundamental investment restrictions on an aggregate basis, to the extent those restrictions are applicable to the investment activities of the Subsidiary. The Fund is the sole shareholder of its Subsidiary and does not expect shares of its Subsidiary to be offered or sold to other investors. An election has been made to cause the Subsidiary to be a disregarded entity for U.S. federal income tax purposes; accordingly, the assets and income of the Subsidiary will be treated for U.S. federal income tax purposes no differently from the other assets and income of the Fund.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

In general, the Fund’s investments will be spread over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

 

The Fund may participate as a purchaser in initial public offerings of securities (“IPOs”). An IPO is a company’s first offering of stock to the public.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

The Fund may also seek to increase its income by lending portfolio securities.

 

The Fund will invest in derivatives, including put and call options, futures, contracts for differences, forward contracts and swaps, in lieu of investing directly in a security, currency or instrument, for hedging and non-hedging purposes. Contracts for differences offer exposure to price changes in an underlying security without ownership of such security, typically by providing investors the ability to trade on margin. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. The Adviser may not be successful in its strategy of taking long positions in securities the Adviser believes to be undervalued and short positions in securities the Adviser believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio may make. Investments the Fund makes may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

 

 

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.

 

 

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 Adviser is incorrect in its expectation of price fluctuations. Losses incurred by the Fund in writing options can be potentially unlimited.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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.

 

 

Segregated Account Risk. A security held in a segregated account cannot be sold while the position it is covering is outstanding, unless it is replaced with a similar security. As a result, there is a possibility that segregation of a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

 

 

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling is speculative and also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; the additional costs that may be incurred; and the potential loss of investment flexibility caused by the Fund’s obligations to provide collateral to the lender and set aside assets to cover the open position. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in the value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited. The use of short sales may cause the Fund to have higher expenses than those of other equity mutual funds because of higher transaction costs, premiums, interest or dividends payable to the lender.

 

 

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.

 

 

Subsidiary Risks. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

The bar chart and table below illustrate the long-term performance of the Fund. The bar chart below shows you how the performance of the Fund’s Institutional Class has varied year by year and provides some indication of the risks of investing in the Fund. The bar chart assumes reinvestment of dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. Updated performance information is available at www.boston-partners.com or 1-888-261-4073.

 

The Fund commenced operations as a series of The RBB Fund, Inc. on December 15, 2015, when substantially all of the assets of Boston Partners Emerging Markets Long/Short Equity (the “Prior Account”) transferred to the Fund. The Fund is managed in all material respects in a manner equivalent to the management of the Prior Account. Accordingly, the performance information shown below for periods prior to December 15, 2015 is that of the Prior Account. The Fund’s objectives, policies, guidelines and restrictions are in all material respects equivalent to the Prior Account. The Fund is managed by Joseph F. Feeney, Jr. and Paul Korngiebel, the same Prior Account portfolio managers that managed the Prior Account since its inception in 2015. The Prior Account was not registered under the Investment Company Act of 1940, as amended (“1940 Act”), and thus was not subject to certain investment and operational restrictions that are imposed by the 1940 Act. If the Prior Account had been registered under the 1940 Act, its performance may have been adversely affected. Accordingly, future Fund performance may be different than the Prior Account’s restated past performance. The Prior Account’s performance has been restated to reflect estimated expenses of the Fund. After-tax performance returns are not included for the Prior Account. The Prior Account was not a regulated investment company under Subchapter M of the Internal Revenue Code and therefore did not distribute current or accumulated earnings and profits and was not subject to the diversification and source of income requirements applicable to regulated investment companies.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in a diversified portfolio consisting primarily of equity securities, such as common stocks of issuers across the capitalization spectrum and identified by the Adviser as having value characteristics.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

The Adviser examines various factors in determining the value characteristics of such issuers including price to book value ratios and price to earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, such as return on equity and earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Fund may also invest up to 20% of its total assets in non U.S. dollar denominated securities.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

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 invest up to 10% of its net assets in securities that can be converted into common stock, such as certain debt securities and preferred stock.

 

The Fund may hedge overall portfolio exposure up to 40% of its net assets through the purchase and sale of index and individual put and call options.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

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 Adviser is incorrect in its expectation of price fluctuations.

 

 

Small/Mid-Cap Companies Risk. Investing in securities of companies with micro, small or mid-sized capitalizations tends to be riskier than investing in securities of companies with large capitalizations. Securities of companies with micro, small and mid-sized capitalizations tend to be more volatile than those of large cap companies and, on occasion, may fluctuate in the opposite direction of large cap company securities or the broader stock market averages.

 

 

The small capitalization equity securities in which the Fund invests may be traded only in the over-the- counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund was 33% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in a diversified portfolio consisting primarily of equity securities, such as common stocks of issuers with small market capitalizations and identified by the Adviser as having value characteristics. A small market capitalization issuer generally is considered to be one whose market capitalization is, at the time the Fund makes the investment, similar to the market capitalization of companies in the Russell 2000® Value Index. The Russell 2000® Value Index is an unmanaged index that contains stocks from the Russell 2000® Index with less than average growth orientation. As of November 30, 2021, the median market capitalization of the Russell 2000® Value Index was $1.0 billion and the largest stock was $18.3 billion. Please note that this range is as of a particular point in time and is subject to change.

 

The Fund generally invests in the equity securities of small companies. The Adviser will seek to invest in companies it considers to be well managed and to have attractive fundamental financial characteristics. The Adviser believes greater potential for price appreciation exists among small companies since they tend to be less widely followed by other securities analysts and thus may be more likely to be undervalued by the market. The Fund may invest from time to time a portion of its assets, not to exceed 20% (under normal conditions) at the time of purchase, in companies with larger market capitalizations.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

The Adviser examines various factors in determining the value characteristics of such issuers including price to book value ratios and price to earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Fund may also invest up to 25% of its total assets in non U.S. dollar-denominated securities.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

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.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Small Cap Companies Risk. The Fund will invest in smaller issuers which are more volatile and less liquid than investments in issuers with a market capitalization greater than the market capitalization of companies in the Russell 2000® Value Index. Small market capitalization issuers are not as diversified in their business activities as issuers with market capitalizations greater than the market capitalization of companies in the Russell 2000® Value Index and are more susceptible to changes in the business cycle.

 

 

The small capitalization equity securities in which the Fund invests may be traded only in the over-the- counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund’s Institutional Class was 88% of the average value of its portfolio.

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 $10,000 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 [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund pursues its 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 without limitation 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 participation. 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 Adviser, 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 the Adviser to be undervalued in the marketplace, focusing on issuers that combine attractive valuations with catalysts for change. The Adviser 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 Adviser 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 Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

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 invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

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.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees in addition to the Fund’s own expenses.Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. 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. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

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 Adviser is incorrect in its expectation of price fluctuations.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage fund and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registrations under the 1940 Act.

 

 

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.

 

 

Small/Mid-Cap Companies Risk. Investing in securities of companies with micro, small or mid-sized capitalizations tends to be riskier than investing in securities of companies with large capitalizations. Securities of companies with micro, small and mid-sized capitalizations tend to be more volatile than those of large cap companies and, on occasion, may fluctuate in the opposite direction of large cap company securities or the broader stock market averages.

 

 

The small capitalization equity securities in which the Fund invests may be traded only in the over-the- counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. Redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

As of the date of this Prospectus, the Boston Partners Global Equity Fund’s Investor Class has not yet commenced operations. The bar chart and table below illustrate the performance of the Fund’s Institutional Class, which is offered in a separate Prospectus. Had the Investor Class been operational during the periods in the chart and table below, it would have had substantially similar annual returns as the Institutional Class because the Investor Class is invested in the same portfolio of securities. Annual returns would differ only to the extent that the Investor Class and Institutional Class do not have the same expenses. The bar chart below shows you how the performance of the Fund’s Institutional Class has varied year by year and provides some indication of the risk of investing in the Fund. The bar chart assumes reinvestment of dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. Performance reflects fee waivers in effect. If fee waivers were not in place, the Fund’s performance would be reduced.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales will be invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage. The Fund invests, both long and short, in securities principally traded in the United States markets. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Adviser will determine the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Fund seeks to construct a portfolio that has less volatility than the United States equity market generally. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

The Fund intends, under normal circumstances, to invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities.

 

Under normal circumstances, the Adviser expects that the Fund’s long positions will not exceed approximately 125% of the Fund’s net assets.

 

The Fund’s long and short positions may involve (without limit) equity securities of foreign issuers that are traded in the markets of the United States. The Fund may also invest up to 20% of its total assets directly in equity securities of foreign issuers.

 

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

 

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 invest from time to time a significant portion of its assets in smaller issuers which are more volatile and less liquid than investments in issuers with larger market capitalizations.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry.

 

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by corporations and other business organizations. High yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the Adviser may not be successful in its strategy of taking long positions in stocks the manager believes to be undervalued and short positions in stocks the manager believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio may make.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

Segregated Account Risk. A security held in a segregated account cannot be sold while the position it is covering is outstanding, unless it is replaced with a similar security. As a result, there is a possibility that segregation of a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

 

 

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises.

 

 

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

The table below compares the average annual total returns for the Fund’s Investor Class both before and after taxes for the past calendar year, past five calendar years and past ten calendar years to the average annual total returns of a broad-based securities market index for the same periods. Although the Fund compares its average total return to a broad-based securities market index, the Fund seeks returns that are not correlated to securities market returns. The Fund seeks to achieve a 12-15% return over a full market cycle; however, there can be no guarantee that such returns will be achieved.

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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund was 61% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund uses a hedged strategy. The Fund actively invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales (i.e. sales of securities the Fund does not own) are invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage.

 

The Fund invests, both long and short, in equity securities issued by large-, mid- and small (or “micro”)-cap companies, as well as other instruments that are convertible into equity securities. Equity securities in which the Fund may invest include exchange-traded and over-the-counter common and preferred stocks, warrants, rights, convertible securities, depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies and 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 may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Fund may also invest in depository receipts and equity securities of foreign companies (denominated in either U.S. dollars or foreign currencies), put and call options, futures, indexed securities and fixed-income securities (including bonds, notes, asset-backed securities, convertible securities, Eurodollar and Yankee dollar instruments, preferred stocks and money market instruments) and high yield securities (commonly referred to as “junk bonds”). Fixed income securities in which the Fund invests include those rated between AAA and D by a nationally recognized statistical rating organization (“NRSRO”), or deemed of comparable quality by the Adviser. The Adviser may also temporarily invest uninvested cash in money market funds and similar collective investment vehicles. The Fund may also seek to increase its income by lending portfolio securities.

 

The Adviser determines the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Fund seeks to construct a portfolio that has less volatility than the U.S. equity market by investing less than 100% of its assets in net long positions. Selection of individual securities to be held long or sold short will be based on a mix of quantitative techniques and fundamental security analysis. The Adviser selects stocks on the basis of three criteria: value, fundamental business strength and momentum. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

Although the Fund seeks to follow a hedged strategy, there can be no assurance that the Fund’s portfolio or investments will be insulated from market moves or effectively hedged against risk.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange-traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

The principal derivative instruments in which the Fund invests are futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an Adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations (of any rating, including defaulted securities and unrated securities), including bonds and debentures, issued by corporations and business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. Less liquid securities that the fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

Indexed Securities Risk. The Fund may invest in indexed securities whose value is linked to securities indices. Most such securities have values that rise and fall according to the change in one or more specified indices and may have characteristics similar to direct investments in the underlying securities. Depending on the index, such securities may have greater volatility than the market as a whole.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. The Adviser may be incorrect in the stocks it buys and believes to be undervalued and in stocks it sells short and believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the price of these stocks will not move even lower.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 300%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; the additional costs that may be incurred; and the potential loss of investment flexibility caused by the Fund’s obligations to provide collateral to the lender and set aside assets to cover the open position. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.

 

 

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold, and sell Investor Class shares of the Fund. You may be required to pay commissions and/or other forms of compensation to a broker for transactions in Investor Class shares, which are not reflected in the table or the example below.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
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 Total annual Fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended August 31, 2021, the portfolio turnover rate for the Fund was 102% of the average value of its portfolio.

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 $10,000 in the Fund for the time periods indicated and that you sell your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and Fund operating expenses remain the same (taking into account the contractual expense limitation until its expiration). Although your actual costs and returns might be different, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Summary of Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales will be invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage The Fund invests, both long and short, in securities issued by U.S. and non-U.S. companies of any capitalization size.

 

With a long position, the Fund purchases a stock outright; with a short position, the Fund sells a security that it does not own and must borrow to meet its settlement obligations. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Adviser will determine the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, including return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

 

The Fund may invest in all types of equity and equity-related securities, including without limitation exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies (including exchanged-traded funds (“ETFs”)), real estate investment trusts (“REITs”), and equity participation. 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 Adviser, 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’s portfolio is rebalanced regularly. The Adviser assesses each investment’s changing characteristics relative to its contribution to portfolio risk. The Adviser will sell an investment held long or close out a short position that the Adviser believes no longer offers an appropriate return-to-risk trade-off.

 

Under normal circumstances, the Adviser expects to sell securities short so that the Fund’s portfolio is approximately 50% net long with an average of between 30% and 70% net long.

 

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

 

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

 

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 invest from time to time a significant portion of its assets in smaller issuers which are more volatile and less liquid than investments in issuers with larger market capitalizations.

 

The Fund may invest up to 15% of its net assets in illiquid investments, including investements that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

 

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry. The Fund is non-diversified and may invest in fewer securities at any one time than a diversified fund.

 

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by U.S. and foreign corporations and other business organizations (e.g. trusts or limited liability companies). Such high yield debt obligations are not considered to be investment grade. Non-investment grade fixed income securities (commonly known as “junk bonds”) are rated BB or lower by S&P Global, or have a comparable rating by another nationally recognized statistical rating organization (or, if unrated are determined by the Adviser to be of comparable quality at the time of investment). The Fund may invest in securities of the lowest rating category, including securities in default. The Adviser may, but is not required to, sell a bond or note held by the Fund in the event that its credit rating is downgraded.

 

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.

 

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, 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 objectives. The Adviser will determine when market conditions warrant temporary defensive measures.

Risk [Heading] rr_RiskHeading Summary of Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

 

 

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.

 

 

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.

 

 

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

 

 

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

 

 

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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

 

 

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

 

 

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

 

 

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. 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. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

 

 

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

 

 

Illiquid Investments Risk. Investing in illiquid investments 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 investments 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. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

 

 

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 Adviser cannot guarantee continued access to IPOs.

 

 

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the Adviser may not be successful in its strategy of taking long positions in stocks the manager believes to be undervalued and short positions in stocks the manager believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio may make.

 

 

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

 

 

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 Adviser is incorrect in its expectation of price fluctuations. Losses incurred by the Fund in writing options can be potentially unlimited.

 

 

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

 

 

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. 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, engage in dilutive offerings 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. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

 

 

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. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; the additional costs that may be incurred; and the potential loss of investment flexibility caused by the Fund’s obligations to provide collateral to the lender and set aside assets to cover the open position. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited. The use of short sales may cause the Fund to have higher expenses than those of other equity mutual funds because of higher transaction costs, premiums, interest or dividends payable to the lender.

 

 

Segregated Account Risk. A security held in a segregated account cannot be sold while the position it is covering is outstanding, unless it is replaced with a similar security. As a result, there is a possibility that segregation of a large percentage of the Fund’s assets could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

 

 

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

 

 

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

Risk Lose Money [Text] rr_RiskLoseMoney You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus 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.
