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 63% of the average value of its portfolio.

Expense Example Narrative [Text Block]

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 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 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 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.

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.

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 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.

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 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.

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.

Bar Chart Narrative [Text Block]

rr_BarChartNarrativeTextBlock

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.

The Fund normally invests in the equity securities of issuers located in international markets. The Fund will typically invest in equity and equity related instruments of non-U.S. companies of all sizes.

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 COMPANY RISK -- Investing in foreign companies, including direct investments and through ADRs, GDRs and EDRs (collectively, "Depositary Receipts"), which are traded on 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 are generally denominated in a foreign currency. As a result, changes in the value of those currencies 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. Differences in tax and accounting standards and difficulties obtaining information about foreign companies can negatively affect investment decisions. Foreign securities may also be more difficult to value than securities of U.S. issuers. While Depositary Receipts provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in Depositary Receipts continue to be subject to many of the risks associated with investing directly in foreign securities.

GEOGRAPHIC RISK -- The Fund's investments may be focused in particular countries or 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.

EMERGING MARKETS SECURITIES RISK -- Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in foreign 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, the securities markets of emerging market countries may consist of companies with smaller market capitalizations and 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.

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 or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency hedged. In either event, the dollar value of an investment in the Fund would be adversely affected.

SMALL- AND MID-CAPITALIZATION COMPANY RISK -- The small- and mid-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small- and mid-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small- and mid-cap stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange.

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.

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.

ETF RISK -- ETFs are pooled investment vehicles, such as registered investment companies and grantor trusts, whose shares are listed and traded on U.S. stock exchanges or otherwise traded in the over-the-counter market. To the extent that the Fund invests in ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities comprising the index on which the ETF is based and the value of the Fund's investment will fluctuate in response to the performance of the underlying index.

DERIVATIVES RISK -- The Fund's use of futures, forwards, options, swaps, warrants, structured notes and P-Notes for all purposes, including speculative purposes, is subject to market risk, leverage risk, correlation risk, liquidity risk, credit risk and valuation risk. In addition, the Fund's use of derivatives for hedging purposes is subject to hedging risk. Leverage risk, liquidity risk, credit risk and hedging risk are described below. Market risk is the risk that the market value of an investment may move up and down, sometimes rapidly and unpredictably. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Valuation risk is the risk that the derivative may be difficult to value and/or valued incorrectly. Each of these risks could cause the Fund to lose more than the principal amount invested in a derivative instrument.

LEVERAGE RISK -- The use of leverage can 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.

LIQUIDITY RISK -- The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance.

CREDIT RISK -- The risk that the issuer of a security or the counterparty to a contract will default or otherwise become unable to honor a financial obligation.

HEDGING RISK -- The Fund may use derivative instruments for hedging purposes. Hedging through the use of these instruments does not eliminate fluctuations in the underlying prices of the securities that the Fund owns or intends to purchase or sell. While entering into these instruments tends to reduce the risk of loss due to a decline in the value of the hedged asset, such instruments also limit any potential gain that may result from the increase in value of the asset. There can be no assurance that any hedging strategy will be effective or that there will be a hedge in place at any given time.

GROWTH INVESTMENT STYLE RISK -- The Fund invests in equity securities of companies that the Adviser believes will increase their earnings at a certain rate that is generally higher than the rate expected for non-growth companies. If a growth company does not meet these expectations, the price of its stock may decline significantly, even if it has increased earnings. Many growth companies do not pay dividends. Companies that pay dividends often have lower stock price declines during market downturns. Over time, a growth investing style may go in and out of favor, causing the Fund to sometimes underperform other equity funds that use differing investing styles.

VALUE INVESTMENT STYLE RISK -- Value investing focuses on companies with stocks that appear undervalued in light of factors such as the company's earnings, book value, revenues or cash flow. 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" can continue to be undervalued by the market for long periods of time.

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.

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.

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.

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.

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.

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 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 may fall over short or extended periods of time. Historically, the equity market has moved in cycles, and the value of the Fund's securities may fluctuate 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.

SMALL CAPITALIZATION COMPANY RISK -- The smaller capitalization companies that the Fund invests in may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, investments in these small companies may pose additional risks, including liquidity risk, because these companies tend to 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. These securities may be traded over-the-counter or listed on an exchange. The Fund is also subject to the risk that the Adviser's particular investment style, which focuses on small capitalization stocks, may underperform other segments of the equity market or the equity market as a whole.

FOREIGN COMPANY RISK -- Investing in foreign companies, including direct investments and investments through ADRs, 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. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax 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.

EXCHANGE-TRADED FUND RISK -- ETFs are pooled investment vehicles, such as registered investment companies and grantor trusts, whose shares are listed and traded on U.S. and non-U.S. stock exchanges or otherwise traded in the over-the-counter market. To the extent that the Fund invests in ETFs, the Fund will be subject to substantially the same risks as those associated with the direct ownership of the securities comprising the index on which the ETF is based or the ETF's other holdings and the value of the Fund's investment will fluctuate in response to the performance of the underlying index or holdings. ETFs typically incur fees that are separate from those of the Fund. Accordingly, the Fund's investments in ETFs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the ETFs' operating expenses, in addition to paying Fund expenses. Because the value of ETF shares depends on the demand in the market, shares may trade at a discount or premium to their net asset value ("NAV") and the Adviser may not be able to liquidate the Fund's holdings at the most optimal time, which could adversely affect the Fund's performance.

DERIVATIVES RISK -- The Fund's use of options and futures is subject to market risk, leverage risk, correlation risk, hedging 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. Hedging risk is the risk that derivatives instruments used for hedging purposes may also limit any potential gain that may result from the increase in value of the hedged asset. To the extent that the Fund engages in hedging strategies, there can be no assurance that such strategy will be effective or that there will be a hedge in place at any given time. Liquidity risk is the risk that certain securities 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.

MANAGEMENT RISK -- The value of the Fund may decline if the Adviser's judgments about the attractiveness, relative value or potential appreciation of a particular security or strategy prove to be incorrect.

Because a portion of the Fund is selected using a proprietary screening process, the Fund is subject to the additional risk that the Adviser's judgments regarding the investment criteria underlying the screening process may prove to be incorrect.

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.
