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 its most recent fiscal year, the Fund's portfolio turnover rate was 45% 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 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 (including one year of capped expenses in each period) 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 Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of small capitalization companies. The Adviser defines small capitalization companies as companies with market capitalizations, at the time of acquisition, within the range of market capitalizations of companies constituting the Russell 2000 Index. The securities in which the Fund invests are primarily common stock and real estate investment trusts ("REITs").

 

The Adviser uses a value investment strategy based on proprietary fundamental research. Value investing involves buying stocks that, in the view of the Adviser, are out of favor or undervalued relative to their peers. The Adviser emphasizes companies with the ability to generate discretionary cash flow after spending what is required to maintain the business at its current level of revenue, and to redeploy such cash flow to enhance value. The Adviser also looks for the following characteristics:

 

● Stable and predictable business model

 

● Motivated and competent management

 

● Unduly depressed valuation

 

● Catalyst for positive market revaluation

 

To manage risk, the Adviser seeks to adhere to a strong buy, hold and sell discipline. The Adviser may sell a security if (1) its expected return falls below certain levels due to price appreciation, (2) its market capitalization appreciates above the range of small capitalization securities, (3) there are, in the view of the Adviser, adverse changes in the fundamentals of the issuer, (4) the Adviser believes that the business model of the issuer becomes unpredictable, or (5) the Adviser believes better relative value exists elsewhere.

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

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Equity Market Risk — The risk that stock prices will fall over short or extended periods of time.

 

Small Capitalization Companies Risk — The risk that small capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization stocks may be more volatile than those of larger companies. Small capitalization stocks may be traded over-the-counter or listed on an exchange. The market for small capitalization companies may be less liquid than the market for larger capitalization companies.

 

Value Style Risk — If the Adviser's assessment of market conditions, or a company's value or its prospects for exceeding earnings expectations is inaccurate, the Fund could suffer losses or produce poor performance relative to other funds. In addition, "value stocks" may continue to be undervalued by the market for long periods of time.

 

REIT Risk — REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. REITs are susceptible to the risks associated with direct ownership of real estate, such as the following: declines in property values; increases in property taxes, operating expenses, interest rates or competition; overbuilding; zoning changes; and losses from casualty or condemnation. REITs typically incur fees that are separate from those of the Fund. Accordingly, the Fund's investments in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. REIT operating expenses are not reflected in the fee table and example in this Prospectus.

 

Manager Risk — The performance of the Fund is dependent upon the portfolio managers' skill in making appropriate investments. The Adviser's investment strategy may fail to produce the intended result. As a result, the Fund may underperform its benchmark or peers.

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

The Fund plans to invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of U.S. and non-U.S. companies of any size. For purposes of the Fund's 80% policy, equity securities include common and preferred stock, convertible securities, depositary receipts, and private placements. The Fund will invest at least 40% of its net assets in securities of issuers located outside the U.S. and may invest significantly in securities of issuers located in emerging or frontier markets, which the Adviser defines as countries other than those classified as developed by MSCI.

 

No more than 35% of the Fund's net assets may be invested in securities of companies located in a single country, and the Fund's net assets will be invested in securities of companies located in at least three different countries. As a result of the Adviser's investment strategy, a large portion of the portfolio may be invested in a particular country or region.

 

In addition, the Fund may seek to generate returns by purchasing put options on the S&P 500 Index when the Adviser believes that such put options are highly undervalued and have compelling risk/return profiles.

 

In pursuing the Fund's investment objective, the Adviser seeks to achieve its investment objective through an active, research-driven, fundamentals-based, value-oriented investment process. The Adviser adheres to disciplined, value-driven investment strategies that emphasize securities chosen through in-depth research and follows those securities over time to assess whether they continue to meet the purchase rationale.

 

The Adviser selects equity securities through bottom-up fundamental research. The Adviser's research analysts continually evaluate companies within their defined investable universe based upon a variety of both qualitative and quantitative criteria. Quantitative measures include price-to-earnings, price-to-book value, price-to-sales, price-to-net present value, price-to-free cash flow, sustainable dividend yield and price-to-liquidation/replacement value. The qualitative analysis assists the research team in producing an understanding of franchise quality, management strength, corporate strategy, barriers-to-entry, shareholder value orientation, operating and industry fundamentals and competitive advantage. The research-driven investment process seeks to add value through active management and by selecting securities of companies that, in the Adviser's opinion, are misperceived and undervalued by the market. The Adviser makes use of convertible securities on an opportunistic basis as an alternative to the underlying equity in addition to also considering securities across a company's capital structure, including debt.

 

The Adviser may sell a security when the Adviser believes that it has found a better alternative, the security's fundamentals have deteriorated, or the security's value has appreciated and approached the Adviser's estimated intrinsic value.

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

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Equity Risk — Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

 

Foreign/Emerging and Frontier Market Security Risk — Non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. Non-U.S. securities are also subject to risks associated with the potential imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country. These additional risks may be heightened with respect to emerging and frontier market countries since political turmoil and rapid changes in economic conditions are more likely to occur in these countries.

 

Geographic Focus Risk — To the extent that a large portion of its portfolio is invested in a particular country or region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers within that country or region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.

 

Small and Medium Capitalization Companies Risk — The risk that small and medium capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange. The market for small and medium capitalization companies may be less liquid than the market for larger capitalization companies.

 

Foreign Currency Risk — As a result of the Fund's investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to foreign currency risk. Foreign currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected.

 

Depositary Receipts Risk — Depositary receipts are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory and tax environments.

 

Convertible and Preferred Securities Risk — Convertible and preferred securities have many of the same characteristics as stocks, including many of the same risks. In addition, convertible securities may be more sensitive to changes in interest rates than stocks. Convertible securities may also have credit ratings below investment grade, meaning that they carry a higher risk of failure by the issuer to pay principal and/or interest when due.

 

Purchasing Put Options Risk — A put option gives the buyer the right, but not the obligation, to sell an underlying instrument at a specific exercise price before a specific expiration date. When the Fund purchases a put option on an index, it may lose the entire premium paid if the index does not fall below the exercise price before the expiration date.

 

Liquidity Risk — Certain securities, including privately placed securities and securities of emerging or frontier market issuers, may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance.

 

Private Placements Risk — Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded.

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 its most recent fiscal year, the Fund's portfolio turnover rate was 45% of the average value of its portfolio.

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

The Fund, under normal market conditions, will invest primarily in equity securities of companies located throughout the world. The equity securities in which the Fund plans to invest include common and preferred stock, convertible securities, depositary receipts, and private placements. The Fund generally follows a multi-capitalization approach that focuses on mid- to large-capitalization companies, but the Fund may also invest in small capitalization companies. The Fund may invest significantly in securities of issuers located in emerging or frontier markets, which the Adviser defines as countries other than those classified as developed by MSCI. No more than 35% of the Fund's net assets may be invested in securities of companies located in a single country. As a result of the Adviser's investment strategy, a large portion of the portfolio may be invested in a particular country or region. The Fund may invest up to 15% of its net assets in U.S. domiciled businesses that have significant business activities outside the United States, as determined by the Adviser.

 

In addition, the Fund may seek to generate returns by purchasing put options on the MSCI Emerging Markets Index when the Adviser believes that such put options are highly undervalued and have compelling risk/return profiles.

 

In pursuing the Fund's investment objective, the Adviser seeks to achieve its investment objective through an active, research-driven, fundamentals-based, value-oriented investment process. The Adviser adheres to disciplined, value-driven investment strategies that emphasize securities chosen through in-depth research and follows those securities over time to assess whether they continue to meet the purchase rationale.

 

The Adviser selects equity securities through bottom-up fundamental research. The Adviser's research analysts continually evaluate companies within their defined investable universe based upon a variety of both qualitative and quantitative criteria. Quantitative measures include price-to-earnings, price-to-book value, price-to-sales, price-to-net present value, price-to-free cash flow, sustainable dividend yield and price-to-liquidation/ replacement value. The qualitative analysis assists the research team in producing an understanding of franchise quality, management strength, corporate strategy, barriers-to-entry, shareholder value orientation, operating and industry fundamentals and competitive advantage. The research-driven investment process seeks to add value through active management and by selecting securities of companies that, in the Adviser's opinion, are misperceived and undervalued by the market. The Adviser makes use of convertible securities on an opportunistic basis as an alternative to the underlying equity in addition to also considering securities across a company's capital structure, including debt.

 

The Adviser may sell a security when the Adviser believes that it has found a better alternative, the security's fundamentals have deteriorated, or the security's value has appreciated and approached the Adviser's estimated intrinsic value. When the Adviser believes that market conditions are unfavorable to its style of investing, or is otherwise unable to locate attractive investment opportunities, the Fund may hold a higher level of cash or money market instruments. Due to a larger percentage of such holdings, the Fund may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested in equity securities.

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

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Equity Risk — Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

 

Foreign/Emerging and Frontier Market Security Risk — Non-U.S. securities may be subject to additional risks due to, among other things, political, social and economic developments abroad, currency movements and different legal, regulatory and tax environments. Non-U.S. securities are also subject to risks associated with the potential imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country. These additional risks may be heightened with respect to emerging and frontier market countries since political turmoil and rapid changes in economic conditions are more likely to occur in these countries.

 

Geographic Focus Risk — To the extent that a large portion of its portfolio is invested in a particular country or region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers within that country or region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.

 

Foreign Currency Risk — As a result of the Fund's investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to foreign currency risk. Foreign currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected.

 

Depositary Receipts Risk — Depositary receipts are certificates evidencing ownership of shares of a foreign issuer that are issued by depositary banks and generally trade on an established market. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities, including, among other things, political, social and economic developments abroad, currency movements, and different legal, regulatory and tax environments.

 

Convertible and Preferred Securities Risk — Convertible and preferred securities have many of the same characteristics as stocks, including many of the same risks. In addition, convertible securities may be more sensitive to changes in interest rates than stocks. Convertible securities may also have credit ratings below investment grade, meaning that they carry a higher risk of failure by the issuer to pay principal and/or interest when due.

 

Purchasing Put Options Risk — A put option gives the buyer the right, but not the obligation, to sell an underlying instrument at a specific exercise price before a specific expiration date. When the Fund purchases a put option on an index, it may lose the entire premium paid if the index does not fall below the exercise price before the expiration date.

 

Liquidity Risk — Certain securities, including privately placed securities and securities of emerging or frontier market issuers, may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on Fund management or performance.

 

Private Placements Risk — Investment in privately placed securities may be less liquid than in publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable if their securities were publicly traded.

 

Small and Medium Capitalization Companies Risk — The risk that small and medium capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange. The market for small and medium capitalization companies may be less liquid than the market for larger capitalization companies.

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 its most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio. Instruments with a maturity of one year or less at the time of acquisition are excluded from the calculation of the portfolio turnover rate. These instruments would generally include the futures contracts in which the Fund may invest since such contracts generally have remaining maturities of less than one year. If these instruments were included in the calculation, the Fund would have a higher portfolio turnover rate.

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

The Fund allocates its assets among three macro or broad asset classes (equities, fixed income and currencies) by taking long and/or short positions in futures contracts based on instruments in each asset class.

 

A futures contract is an agreement between two parties whereby one party agrees to sell and the other party agrees to buy a specified amount of an underlying instrument at an agreed upon price and time. Agreeing to buy the underlying instrument is called buying a futures contract or taking a long position in the contract. Likewise, agreeing to sell the underlying instrument is called selling a futures contract or taking a short position in the contract. As the owner of a long position in a futures contract, the Fund will benefit from an increase in the price of the underlying instrument, and, as the owner of a short position, the Fund will benefit from a decrease in the price of the underlying instrument.

 

Through its investments in futures contracts, the Fund will principally have exposure to (i) large-cap equity markets, (ii) investment-grade government securities of any maturity, (iii) interest rates and (iv) currencies.

 

Under normal conditions, the Fund will have exposure to the equity markets, government securities, interest rates or currencies of at least three countries, including the United States, and will have exposure to non-U.S. equity markets, government securities, interest rates and currencies (measured on a gross basis) equal to at least 40% (or, if conditions are not favorable, at least 30%) of its total assets. From time to time, the Fund may focus its investments in a particular geographic region, such as Europe or Asia.

 

The Fund purchases and sells futures contracts based on trading and sizing signals generated by a proprietary systematic global asset allocation ("GAA") investment model designed by the Adviser that combines various quantitative investment strategies (e.g. econometric, technical and relative value) to seek to generate returns across asset classes and investment timeframes.

 

The Fund's use of futures contracts will have the economic effect of financial leverage. Financial leverage magnifies the exposure to the swings in prices of an instrument underlying a futures contract and results in increased volatility, which means that the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund did not use futures contracts. Leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund's exposure to an instrument and may cause the Fund's net asset value ("NAV") to be volatile. A decline in the Fund's assets due to losses magnified by futures contracts may require the Fund to liquidate portfolio positions to satisfy its obligations, to meet redemption requests or to meet asset coverage requirements under the Investment Company Act of 1940, as amended (the "1940 Act"), when it may not be advantageous to do so.

 

In order to meet the 1940 Act asset coverage requirements with respect to the use of futures contracts, and earn income, the Fund may hold significant amounts of cash and cash equivalents.

 

When taking into account instruments with a maturity of one year or less at the time of acquisition, the Fund's strategy will result in frequent portfolio trading and high portfolio turnover.

 

The Fund is classified as "non-diversified," which means that it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration Under normal conditions, the Fund will have exposure to the equity markets, government securities, interest rates or currencies of at least three countries, including the United States, and will have exposure to non-U.S. equity markets, government securities, interest rates and currencies (measured on a gross basis) equal to at least 40% (or, if conditions are not favorable, at least 30%) of its total assets.

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

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Systematic or Quantitative Process Risk – There is potential for shortfall in any investment process due to a variety of factors including, but not limited to, data and system imperfections, analyst judgment, and the complex nature of designing and implementing portfolio construction systems and other quantitative models. Such shortfalls in systematic or quantitative processes in particular pose broader risk because they may be more pervasive in nature. Furthermore, the Adviser's systems may not necessarily perform in a manner in which they have historically performed or were intended to perform.

 

Derivatives Risk – The Fund's use of futures is subject to market risk, leverage risk, correlation risk and liquidity risk. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Leverage risk is the risk that the use of leverage may amplify the effects of market volatility on the Fund's share price and may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly or at all with the underlying asset, rate or index. Liquidity risk is the risk that certain derivatives may be difficult or impossible to sell at the time and the price that the Fund would like. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument.

 

The Fund's use of futures is also subject to the following risks of the underlying instruments:

 

Equity Risk – The market prices of equity securities may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

 

Fixed Income Risk – Fixed income securities are subject to a number of risks, including credit and interest rate risks. Credit risk is the risk that the issuer or obligor will not make timely payments of principal and interest. 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. Interest rate risk is the risk that the value of a fixed income security will fall when interest rates rise. In general, the longer the maturity and the lower the credit quality of a fixed income security, the more likely its value will decline.

 

Foreign Company Risk – Investing in foreign companies, either directly or through foreign futures contracts, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the "SEC") and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities.

 

Foreign Currency Risk – Foreign currency risk is the risk that changes in foreign currency exchange rates may negatively affect the value of the Fund's investments. Foreign currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad.

 

Geographic Focus Risk – The Fund's investments may be focused in particular geographic regions and, therefore, the Fund will be more susceptible to adverse market, political, regulatory, and geographic events affecting those regions than a fund that does not focus its investments in a particular region.

 

Non-U.S. Government Securities Risk – Foreign sovereign debt securities are subject to the risks that: (i) the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or interest when it becomes due, due to factors such as debt service burden, political constraints, cash flow problems and other national economic factors; (ii) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling or additional lending to defaulting governments; and (iii) there is no bankruptcy proceeding by which defaulted sovereign debt may be collected in whole or in part.

 

U.S. Government Securities Risk – U.S. Government securities are not guaranteed against price movements due to changing interest rates.

 

Non-Diversification Risk – The Fund is classified as "non-diversified," which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent that the Fund invests its assets in a smaller number of issuers, the Fund will be more susceptible to negative events affecting those issuers than a diversified fund.

 

Portfolio Turnover Risk – The Fund is subject to portfolio turnover risk since it may buy and sell investments frequently. Such a strategy often involves higher expenses, including brokerage commissions, and may increase the amount of capital gains (in particular, short term gains) realized by the Fund. Shareholders may pay tax on such capital gains.

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 its most recent fiscal year, the Fund's portfolio turnover rate was 57% of the average value of its portfolio.

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

In pursuing the Fund's objective, the Adviser strives to build a portfolio comprised of approximately 35-60 equity securities (principally common and preferred stock) the Adviser believes have above average prospects for growth. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of large-capitalization companies. This investment policy may be changed by the Fund upon 60 days' prior written notice to shareholders. The Fund considers large-capitalization companies to be companies with market capitalizations greater than $3 billion at the time of purchase. The Adviser expects investments in foreign companies, including emerging market companies and American Depositary Receipts ("ADRs"), will typically represent less than 25% of the Fund's assets.

 

In constructing the Fund's portfolio, the Adviser utilizes a bottom-up approach by first identifying companies that meet strict fundamental criteria and then performing a qualitative review on each identified company. The Adviser's research also may include initial interviews and continuing contact with company management. In selecting stocks for the Fund's portfolio, the Adviser looks for companies that it believes possess the following quantitative characteristics: (i) accelerating earnings growth; (ii) strong balance sheet; and (iii) attractive valuation as measured by price/earnings to growth ratio. In addition, the Adviser seeks to identify companies that it believes possess the following qualitative characteristics: (i) superior company management; (ii) unique market position and broad market opportunities; and (iii) solid financial controls and accounting. The Adviser may sell a security if: (i) the security reaches or falls below a predetermined price target; (ii) a change to a company's fundamentals occurs that negatively impacts the Adviser's original investment thesis; (iii) the security underperforms versus its industry peer group; or (iv) the Adviser identifies a more attractive investment opportunity.

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

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Equity Risk – Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

 

Growth Style Risk – The price of equity securities rises and falls in response to many factors, including the historical and prospective earnings of the issuer of the stock, the value of its assets, general economic conditions, interest rates, investor perceptions, and market liquidity. The Fund may invest in securities of companies that the Adviser believes have superior prospects for robust and sustainable growth of revenues and earnings. These may be companies with new, limited or cyclical product lines, markets or financial resources, and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.

 

Foreign Company Risk – Investing in foreign companies, including direct investments and through ADRs, which are traded on U.S. exchanges and represent an ownership in a foreign security, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign companies generally are denominated in a foreign currency. Changes in the value of a currency compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may occur separately from, and in response to, events that do not otherwise affect the value of the security in the issuer's home country. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the "SEC") and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publically available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which would reduce income received from the securities comprising the portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers. While ADRs provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities.

 

Emerging Market Securities Risk – Investments in emerging market securities are considered speculative and are subject to heightened risks in addition to the general risks of investing in non-U.S. securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, emerging market securities may be subject to smaller market capitalization of securities markets, which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies.

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 its most recent fiscal year, the Fund's portfolio turnover rate was 71% of the average value of its portfolio.

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

In pursuing the Fund's objective, the Adviser strives to build a portfolio comprised of approximately 30-50 publicly traded equity securities of primarily large capitalization issuers with a history or prospect of paying stable or increasing dividends. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in dividend-paying equity securities. This investment policy may be changed by the Fund upon 60 days' prior written notice to shareholders. While the Fund expects to invest primarily in common and preferred stock, it may also invest in other equity securities, including master limited partnerships ("MLPs") and American Depositary Receipts ("ADRs"). The Adviser expects that investments in foreign securities, including ADRs, will typically represent less than 35% of the Fund's assets.

 

In constructing the Fund's portfolio, the Adviser first identifies companies that it believes possess the following quantitative characteristics: (i) above average dividend growth, sales growth, earnings growth and free cash flow growth; (ii) high current dividend yield; and (iii) a strong balance sheet. In addition, the Adviser seeks to identify companies that it believes possess the following qualitative characteristics: (i) superior company management; (ii) unique market position and broad market opportunities; and (iii) solid financial controls and accounting. The Adviser then performs a fundamental, qualitative review of each identified company, which may include initial interviews and continuing contact with company management. The Adviser may sell a security if: (i) the security reaches or falls below a predetermined price target; (ii) a change to a company's fundamentals occurs that negatively impacts the Adviser's original investment thesis; (iii) there is a change in a company's dividend policy; or (iv) the Adviser identifies a more attractive investment opportunity.

 

The Fund may buy and sell investments frequently in seeking to achieve its objective.

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

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Dividend Paying Stocks Risk – The Fund's emphasis on dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the market. Also, a company may reduce or eliminate its dividend.

 

Equity Risk – Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund.

 

Foreign Company Risk – Investing in foreign companies, including direct investments and through ADRs, which are traded on U.S. exchanges and represent an ownership in a foreign security, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign companies generally are denominated in a foreign currency. Changes in the value of a currency compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may occur separately from, and in response to, events that do not otherwise affect the value of the security in the issuer's home country. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the "SEC") and foreign companies are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publically available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which would reduce income received from the securities comprising the portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers. While ADRs provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities.

 

Preferred Stock Risk – Preferred stocks are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company's assets in the event of a liquidation are generally subordinate to the rights associated with a company's debt securities.

 

MLP Risk – MLPs are limited partnerships in which the ownership units are publicly traded. MLPs often own several properties or businesses (or own interests) that are related to oil and gas industries or other natural resources, but they also may finance other projects. To the extent that an MLP's interests are all in a particular industry, the MLP will be negatively impacted by economic events adversely impacting that industry. Additional risks of investing in a MLP also include those involved in investing in a partnership as opposed to a corporation. For example, state law governing partnerships is often less restrictive than state law governing corporations. Accordingly, there may be fewer protections afforded to investors in a MLP than investors in a corporation. For example, investors in MLPs may have limited voting rights or be liable under certain circumstances for amounts greater than the amount of their investment. In addition, MLPs may be subject to state taxation in certain jurisdictions which will have the effect of reducing the amount of income paid by the MLP to its investors.

 

Foreign Currency Risk – As a result of the Fund's investments in securities or other investments denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case, the dollar value of an investment in the Fund would be adversely affected.

 

Portfolio Turnover Risk – The Fund is subject to portfolio turnover risk because it may buy and sell investments frequently. Such a strategy often involves higher expenses, including brokerage commissions, and may increase the amount of capital gains (in particular, short term gains) realized by the Fund. Shareholders may pay tax on such capital gains.

The bar chart and the performance table below illustrate the risks and volatility of an investment in the Fund by showing changes in the Fund's Institutional Class Shares' performance from year to year and by showing how the Fund's Institutional Class Shares' average annual total returns for 1 and 5 years and since inception compare with those of a broad measure of market performance. Of course, the Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available on the Fund's website at www.westfieldcapital.com or by calling 1-866-454-0738.

 

The performance shown in the bar chart and performance table for periods prior to July 26, 2013 is the performance of another investment vehicle (the "Predecessor Fund"). Institutional Class Shares of the Fund acquired substantially all of the assets of the Predecessor Fund after the close of business on July 26, 2013. The Predecessor Fund was managed by the Adviser using investment policies, objectives and guidelines that were in all material respects equivalent to the management of the Fund. However, the Predecessor Fund was not a registered mutual fund and so it was not subject to the same investment and tax restrictions as the Fund. If it had been, the Predecessor Fund's performance may have been lower. The performance information in the bar chart and table for periods prior to July 26, 2013 reflects all fees and expenses incurred by the Predecessor Fund. The performance information for periods prior to July 26, 2013 has not been adjusted to reflect Institutional Class Shares expenses. If the performance information for periods prior to July 26, 2013 had been adjusted to reflect Institutional Class Shares expenses, the performance may have been lower.

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any government agency. The principal risk factors affecting shareholders' investments in the Fund are set forth below.

 

Dividend Paying Stocks Risk – The Fund's emphasis on dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the market. Also, a company may reduce or eliminate its dividend.

Performance Table Narrative rr_PerformanceTableNarrativeTextBlock

This table compares the Fund's Investor Class Shares' average annual total returns for the periods ended December 31, 2019 to those of appropriate broad based indices.

 

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts ("IRAs"). After-tax returns cannot be calculated for periods before the Fund's registration as a mutual fund and they are, therefore, unavailable.
