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 may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 104% of the average value of its portfolio.

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

13D Management LLC (the “Adviser”), seeks to achieve the Fund’s investment objective by investing primarily in common stocks of U.S. companies of any market capitalization that are the target of shareholder activism. The Adviser defines an activist as an investor who holds or takes a long position in a company’s shares and either (A) has a history of activist investing and/or (B) has publicly disclosed a catalyst for change such as seeking board seats, improving operations and/or corporate governance practices, spinning-off an operating division or selling a significant amount of company assets (such an investor being referred to herein as an “activist”). The Adviser reviews all material activist situations and makes investment decisions based on its knowledge of the activist investor involved, the industry, the shareholder base, the activist’s average cost, its strategy and the Adviser’s determination of the chance of success and potential impact on share price. The Adviser only selects situations where the shareholder will be improving or participating in corporate governance or otherwise influencing management. Accordingly, approximately 75% of the Fund’s portfolio positions has historically had a shareholder representative on the board of directors who advocates for best-in-class corporate governance practices and a shareholder focused mentality. The Adviser does not only select companies with good corporate governance, because it believes there is more of a social and economic benefit in identifying poor corporate governance companies and supporting a transition to good corporate governance. Implementing best corporate governance practices can range from completely changing corporate culture to replacing entrenched, conflicted and self-dealing management teams. It is the Adviser’s experience that it is the governance element that also leads to environmental and social improvements in the business practices of the Fund’s portfolio companies. Every portfolio position contains an engaged investor and most contain a shareholder representative on the board of directors.

 

The Adviser uses the following selection guidelines to create and manage the Fund’s investment portfolio:

 

Selecting Investment Universe:   Identify companies where an activist investor is involved.
     
Weighting Investments:   Different weights will be given to each investment depending on the (i) type of activist intent stated, (ii) the activist involved, (iii) the industry involved, and (iv) the Adviser’s determination as to the chance of activist success.
     
Exiting Investments:   Exiting an investment is an integral part of the investment strategy. The Adviser will exit a position when the activist indicates that it is exiting the investment, the activist becomes a passive investor, or in the Adviser’s opinion, the activist catalyst has changed or weakened.
     

While these guidelines will define the trading horizon, this horizon may change based on other events. For example, an early exit may be warranted after the activist has attained most of its goals, there has been a sufficient return on the investment, and there are other activist opportunities that the Adviser believes offer a better return. The Fund is non-diversified, which means that it may invest in fewer issuers than a diversified fund. The Adviser may engage in frequent buying and selling of securities in managing the Fund’s portfolio.

 

Risk [Heading] rr_RiskHeading Principal Investment Risks:
Risk [Text Block] rr_RiskTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s net asset value and performance.

 

●Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as worldwide pandemic, terrorist attacks, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund. For example, COVID-19 global pandemic had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long the impacts of the significant events described above, will last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. Therefore, the Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates can have the same impact on all types of securities and instruments. In times of severe market disruptions, you could lose your entire investment. The Adviser’s specialized research helps to mitigate this risk. In the event, activists have a period of significant underperformance, the Funds may also experience a period of underperformance. The Adviser endeavors to address this risk through diversification across several activists, activist styles, and strategies.

 

●Equity Securities Risk: The prices of equity and preferred securities fluctuate based on changes in a company’s financial condition and overall market and economic conditions. The value of equity securities purchased by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate.

 

●Non-Diversification Risk: The Fund is a non-diversified investment company, which makes the value of the Fund’s shares more susceptible to certain risks than shares of a diversified investment company. The Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

 

●Small and Medium Capitalization Company Risk: The value of small or medium capitalization company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

 

●Conflicts of Interest Risk: The Adviser have conflicts of interest that could interfere with their management of the Fund. These conflicts, which are described in more detail in the Fund’s Statement of Additional Information (“SAI”). The principal owner of the Adviser also operates an institutional research firm which is under common control of the Adviser. The Adviser’s affiliate publishes reports on all material Fund filings to subscribers. The affiliate is not a registered investment adviser and the information contained in the reports is not organized or presented in a manner that suggests the holding, purchase or sale of any security. The subscribers to the reports are a variety of organizations including investment banks and law firms, many long/short hedge funds, large institutional investors, activist hedge funds, investor relations companies and proxy solicitors. Although the securities of companies described in the reports may be eligible for the Fund’s portfolio, the reports do not indicate whether or not securities of such companies will be bought or sold by the Fund. In addition, subscribers receive no nonpublic information regarding holdings of the Fund’s portfolio. However, subscribers may make their own investment decisions using information contained in the reports. If subscribers buy or sell securities that are described in the reports, this could negatively impact the price of securities bought or sold by the Fund.

 

●Management Risk: The Adviser’s dependence on its activist strategy and objective judgments about the attractiveness, value and potential appreciation of particular securities in which the Fund invests may prove to be incorrect as there is no guarantee that the Adviser’s investment strategy will produce the desired results.

 

●Regulatory Risk: Legal, tax, and regulatory developments may adversely affect the Fund. The regulatory environment for the Fund is evolving, and changes in the regulation of investment funds and other financial institutions or products, and their trading activities and capital markets, or a regulator’s disagreement with the Fund’s interpretation of the application of certain regulations, may adversely affect the ability of the Fund to pursue its investment strategy.

 

●Shareholder Concentration Risk: The Fund is used as an investment in certain model portfolios or other asset allocation programs sponsored by financial intermediaries and may have a large percentage of its shares held in such programs. The Fund may experience large redemptions or large purchases if any of these programs reduce or increase their targeted allocations to the Fund. Other large investors also may have a significant ownership stake in the Fund. Large redemption or purchase activity could have adverse effects on performance to the extent that the Fund incurs additional costs or is required to sell securities, invest cash, or hold a relatively large amount of cash at times when it would not otherwise do so.
