Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).  A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account.  These costs, which are not reflected in the 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 14% of its average portfolio value.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund will invest at least 80% of its net assets plus the amount of any borrowings for investment purposes in securities of master limited partnerships (“MLPs”) and pipeline companies.  MLPs, also known as publicly traded partnerships, predominately operate, or directly or indirectly own, energy-related assets.  Pipeline companies are defined as either entities in which the largest component of their assets, cash flow or revenue is associated with the operation or ownership of energy pipelines and complementary assets or other entities operating in the energy infrastructure industry as defined by standard industrial classification (“SIC”).  For purposes of this strategy, MLP and pipeline companies include investment companies that invest primarily in MLP and/or pipeline companies.

The Fund intends to focus its investments primarily in equity securities of MLPs and pipeline companies that own and operate a network of energy infrastructure asset systems that transport, store, distribute, gather and/or process crude oil, refined petroleum products (including biodiesel and ethanol), natural gas or natural gas liquids (“NGLs”). The Fund is non-diversified.

The Fund seeks to achieve its investment objective by investing primarily in equity securities of any capitalization that are publicly traded on an exchange or in the over-the-counter market, consisting of common stock, but also including, among others, MLP and limited liability company (“LLC”) common units; the equity securities issued by MLP affiliates, such as common shares of corporations that own, directly or indirectly, MLP general partner interests; and other investment companies that invest in MLP and pipeline companies.

MLP common units represent an equity ownership interest in an MLP.  Some energy infrastructure companies in which the Fund may invest are organized as LLCs which are treated in the same manner as MLPs for federal income tax purposes.  The Fund may invest in LLC common units which represent an ownership interest in the LLC.  Interests in MLP and LLC common units entitle the holder to a share of the company’s success through distributions and/or capital appreciation.

Pursuant to tax regulations, the Fund may invest no more than 25% of its total assets in the securities of MLPs and other entities treated as qualified publicly traded partnerships.

In addition, the Fund may invest in preferred equity, and convertible securities.  The Fund may also write call options on securities, but will only do so on securities it holds in its portfolio (i.e., covered calls).

Under normal circumstances, the Fund may invest up to: (i) 30% of its total assets in securities denominated in the currency of a non-North American country, which may include securities issued by energy companies organized and/or having securities traded on an exchange outside North America and/or securities of other non-North American companies that are denominated in the currency of a non-North American country; (ii) 20% of its total assets in debt securities of any issuers, including securities which may be rated below investment grade (“junk bonds”) by a nationally recognized statistical rating organization (“NRSRO”) or judged by the Adviser to be of comparable credit quality; (iii) 15% of its net assets in illiquid securities; and (iv) 10% of its total assets in securities of any issuer.  The Fund may invest in other investment companies to the extent permitted by the Investment Company Act of 1940, as amended (the “1940 Act”).  The Fund may invest in permissible securities without regard to the market capitalization of the issuer of such security. The Fund will not have any duration or weighted average maturity restrictions.

Except for investments in illiquid securities, the above investment restrictions apply at the time of purchase, and the Fund will not be required to reduce a position due solely to market value fluctuations in order to comply with these restrictions.  To the extent that market value fluctuations cause illiquid securities held by the Fund to exceed 15% of its net assets, the Fund will take steps to bring the aggregate amount of illiquid securities back within the prescribed limitations as soon as reasonably practical.  Generally, this requirement does not obligate the Fund to liquidate a position where the Fund would incur a loss on the sale.

The Adviser seeks to invest the Fund in securities that offer a combination of yield, growth and quality, intended to result in attractive long-term total returns. The Adviser’s securities selection process includes a comparison of quantitative, qualitative, and relative value factors.  Primary emphasis will be placed on proprietary models constructed and maintained by the Adviser’s in-house investment team, although the Adviser may use research provided by broker-dealers and investment firms. To determine whether a company meets its criteria, the Adviser will generally look for long-lived energy infrastructure companies with essential assets with long economic lives (generally 20 years or more), high barriers to entry, total return potential, predictable revenue and stable operating structures, and experienced, operations-focused management teams.
Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
As with any mutual fund, there are risks to investing.  An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other governmental agency.  Remember, in addition to possibly not achieving your investment goals, you could lose all or a portion of your investment in the Fund over short or even long periods of time.  The principal risks of investing in the Fund are:

General Market Risk.  The Fund is subject to all of the business risks and uncertainties associated with any mutual fund, including the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities.  Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.

Adviser Risk.  The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar strategies if the Adviser cannot successfully implement the Fund’s investment strategies.

Concentration Risk.  The Fund’s strategy of focusing its investments in MLPs and pipeline companies means that the performance of the Fund will be closely tied to the performance of the energy infrastructure industry. The Fund’s focus in this industry presents more risk than if it were broadly diversified over numerous industries and sectors of the economy. An inherent risk associated with any investment focus is that the Fund may be adversely affected if one or two of its investments perform poorly.

Non-Diversified Fund Risk.  Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Equity Securities Risk.  Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value.  This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors, geographic markets, the equity securities of energy infrastructure companies in particular, or a particular company in which the Fund invests.

Foreign Securities Risk.  Investments in securities of foreign companies involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.

MLP Risk.  MLPs are subject to many risks, including those that differ from the risks involved in an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP.  Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. In addition, the value of the Fund’s investment in an MLP will depend largely on the MLP’s treatment as a partnership for U.S. federal income tax purposes.  Furthermore, MLP interests may not be as liquid as other more commonly traded equity securities.

MLP Affiliate Risk.  The performance of securities issued by MLP affiliates, including common shares of corporations that own general partner interests, primarily depends on the performance of an MLP.  The risks and uncertainties that affect the MLP, its operational results, financial condition, cash flows and distributions also affect the value of securities held by that MLP’s affiliate.

Debt Securities Risks.  Investments in fixed income securities will be subject to credit risk, interest rate risk and prepayment risk.  Credit risk is the risk that an issuer will default or fail to pay principal and interest when due.  Interest rate risk is the risk that the value of fixed income securities fluctuates with changes in interest rates (e.g. increases in interest rates result in a decrease in value of fixed income securities).  The Fund will be exposed to heightened interest rate risk as interest rates rise from historically low levels.  Pre-payment risk is the risk that the principal on fixed income securities will be paid off prior to maturity causing the Fund to invest in fixed income securities with lower interest rates.  Duration risk is the risk that holding long duration and long maturity investments will magnify certain other risks, including interest rate risk and credit risk.

Below Investment Grade Debt Securities Risk.  Investments in below investment grade debt securities and unrated securities of similar credit quality as determined by the Adviser (commonly known as “junk bonds”) involve a greater risk of default and are subject to greater levels of credit and liquidity risk.  Below investment grade debt securities have speculative characteristics and their value may be subject to greater fluctuation than investment grade debt securities.

Large Cap Company Risk.  The Fund’s investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.  Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors potentially resulting in lower markets for their common stock. 

Mid Cap and Small Cap Companies Risk.  The mid cap and small cap companies may not have the management experience, financial resources, product or business diversification and competitive strengths of large cap companies.  Therefore, these securities may have more price volatility and be less liquid than the securities of larger, more established companies.

Investment Company and RIC Compliance Risk. The Fund may be subject to increased expenses and reduced performance as a result of its investments in other investment companies and MLPs.  When investing in other investment companies, the Fund bears its pro rata share of the other investment company’s fees and expenses including the duplication of advisory and other fees and expenses.  The Fund’s investment in MLPs presents unusual challenges in qualifying each year as a “regulated investment company” (a “RIC”) under the Internal Revenue Code, a designation which allows the Fund to avoid paying taxes at regular corporate rates on its income.  If for any taxable year the Fund fails to qualify as a RIC, the Fund’s taxable income will be subject to federal income tax at regular corporate rates.  The resulting increase to the Fund’s expenses will reduce its performance and its income available for distribution to shareholders.

Cybersecurity Risk.  Investment advisers, including the Adviser, must rely in part on digital and network technologies (collectively “cyber networks”) to conduct their businesses.  Such cyber networks might in some circumstances be at risk of cyber attacks that could potentially seek unauthorized access to digital systems for purposes such as misappropriating sensitive information, corrupting data, or causing operational disruption.

Covered Call Option Risk.  If the Fund writes a covered call option, during the option’s life the Fund gives up the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but retains the risk of loss should the price of the underlying security decline. Moreover, the writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option.

Illiquid/Restricted Securities Risk.  The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities or close call option positions at an advantageous price or in a timely manner. Illiquid securities may include restricted securities that cannot be sold immediately because of statutory and contractual restrictions on resale.

Energy Infrastructure Industry Risk.  Companies in the energy infrastructure industry are subject to many risks that can negatively impact the revenues and viability of companies in this industry, including, but not limited to risks associated with companies owning and/or operating pipelines, gathering and processing assets, power infrastructure, propane assets, as well as capital markets, terrorism, natural disasters, climate change, operating, regulatory, environmental, supply and demand, and price volatility risks.

Energy Industry Risk.  Companies in the energy industry are subject to many business, economic, environmental, and regulatory risks that can adversely affect the costs, revenues, profits, and viability of companies in the industry. These risks include, but are not limited to, the following: volatility in commodity prices and changes in supply and demand, which may affect the volume of energy commodities transported, processed, stored and or distributed; specific risks associated with companies owning and/or operating pipelines, gathering and processing energy assets; operating risks including outages, structural and maintenance, impairment and safety problems; changes in the regulatory environment at federal, state and local levels, and in foreign markets; environmental regulation and liability risk; terrorism risk; extreme weather and other natural disasters; and capital markets risk, resulting in a higher capital costs or impacting growth and access to capital.

Convertible Securities Risk.  Convertible securities are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both debt security risks and equity risk.  Convertible securities are subject to equity risk especially when their conversion value is greater than the interest and principal value of the bond.  The prices of equity securities may rise or fall because of economic or political changes and may decline over short or extended periods of time.

Preferred Stock Risk.  A preferred stock is a blend of the characteristics of a bond and common stock.  It may offer a higher yield than common stock and has priority over common stock in equity ownership, but it does not have the seniority of a bond and, unlike common stock, its participation in the issuer’s growth may be limited.  Although the dividend on a preferred stock may be set at a fixed annual rate, in some circumstances it may be changed or passed by the issuer.  Preferred stock generally does not confer voting rights.

Who Should Invest

Before investing in the Fund, investors should consider their investment goals, time horizons and risk tolerance. The Fund may be an appropriate investment for investors who are seeking:

·
An investment vehicle for accessing a portfolio of MLP and pipeline companies;

·
A traditional flow-through mutual fund structure with daily liquidity at NAV;

·
Simplified tax reporting through a Form 1099;

·
A fund offering the potential for total return through capital appreciation and current income;

·
A fund that may be suitable for retirement and other tax exempt accounts;

·
Potential diversification of their overall investment portfolio; and

·
Professional securities selection and active management by an experienced adviser.

The Fund is designed for long-term investors and is not designed for investors who are seeking short-term gains. The Fund will take reasonable steps to identify and reject orders from market timers.  See “Shareholder Information – Buying Shares” and “– Redeeming Shares” of the Fund’s Statutory Prospectus.

Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
