Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal period ended November 30, 2017 was 11% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class P Shares of the Fund for the time periods indicated and then redeem all of your Class P Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the expense limitation arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in U.S. and non-U.S. equity or fixed income securities issued by master limited partnerships (“MLPs”) and energy companies. The Fund may invest in fixed income securities without regard to credit quality or duration. The Fund’s investments in energy companies may include: U.S. and non-U.S. companies that (i) are classified by a third party as operating within the oil and gas storage, transportation, refining, marketing, drilling, exploration or production sub-industries or (ii) have at least 50% of their assets, income, sales or profits committed to, or derived from, the exploration, development, production, gathering, transportation (including marine), transmission, terminal operation, processing, storage, refining, distribution, mining or marketing of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products, coal, electricity or other energy sources, energy-related equipment or services. The Fund’s MLP investments may include: MLPs structured as limited partnerships (“LPs”) or limited liability companies (“LLCs”); MLPs that are taxed as “C” corporations; institutional units (“I-Units”) issued by MLP affiliates; private investments in public equities (“PIPEs”) issued by MLPs; and other U.S. and non-U.S. equity and fixed income securities and derivative instruments, including pooled investment vehicles and exchange-traded notes (“ETNs”) that provide exposure to MLPs. The Fund’s investments in MLP securities taxed/structured as partnerships will not exceed 25% of the Fund’s total assets as measured at the time of investment. The Fund intends to concentrate its investments in the energy sector. The Fund will invest in investments across all energy segments (upstream, midstream, downstream), with an emphasis in midstream energy infrastructure companies and MLPs. Midstream energy infrastructure companies include companies that are engaged in the treatment, gathering, compression, processing, transportation, transmission, fractionation, storage and terminalling of natural gas, natural gas liquids, crude oil, refined products or coal. The Fund may also invest up to 20% of its Net Assets in non-energy investments, including equity and fixed income securities of U.S. and non-U.S. companies. The Fund may invest in derivatives, including options, futures, forwards, swaps, options on swaps, structured securities and other derivative instruments. While the Fund may invest in derivatives for hedging purposes, the Fund generally does not intend to hedge its exposures. Derivatives that provide exposure to MLPs or energy companies will be counted towards the Fund’s 80% policy discussed above. The Fund may also invest in privately held companies and companies that only recently began to trade publicly. THE FUND IS NON-DIVERSIFIED UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (“INVESTMENT COMPANY ACT”), AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED MUTUAL FUNDS. The Fund’s benchmark index is the Alerian MLP Index. The Alerian MLP Index is the leading gauge of energy MLPs and is a float-adjusted, capitalization-weighted index, whose constituents represent approximately 85% of total float-adjusted market capitalization.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in U.S. and non-U.S. equity or fixed income securities issued by master limited partnerships (“MLPs”) and energy companies.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Credit/Default Risk.  An issuer or guarantor of fixed income securities or instruments held by the Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. The credit quality of the Fund’s portfolio securities or instruments may meet the Fund’s credit quality requirements at the time of purchase but then deteriorate thereafter, and such a deterioration can occur rapidly. In certain instances, the downgrading or default of a single holding or guarantor of the Fund’s holding may impair the Fund’s liquidity and have the potential to cause significant deterioration in net asset value (“NAV”). These risks are more pronounced in connection with the Fund’s investments in non-investment grade fixed income securities. Derivatives Risk.  The Fund’s use of futures, swaps, options on swaps and other derivative instruments may result in losses. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other instruments, may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of the underlying instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. Energy Sector Risk.  The Fund concentrates its investments in the energy sector, and will therefore be susceptible to adverse economic, business, political, environmental, regulatory or other developments affecting that sector. The energy sector has historically experienced substantial price volatility. MLPs and other companies operating in the energy sector are subject to specific risks, including, among others: fluctuations in commodity prices and/or interest rates; increased governmental or environmental regulation; reduced availability of natural gas or other commodities for transporting, processing, storing or delivering; declines in domestic or foreign production; slowdowns in new construction; extreme weather or other natural disasters; and threats of attack by terrorists on energy assets. Energy companies can be significantly affected by the supply of, and demand for, particular energy products (such as oil and natural gas), which may result in overproduction or underproduction. Additionally, changes in the regulatory environment for energy companies may adversely impact their profitability. Over time, depletion of natural gas reserves and other energy reserves may also affect the profitability of energy companies. Recently, the price of oil, natural gas and other fossil fuels has declined significantly and experienced significant volatility, which has adversely impacted companies operating in the energy sector. There can be no assurance that the price of oil, natural gas and other fossil fuels will not decline further and have a further adverse effect. Due to the low value of oil and natural gas products, energy producers are increasingly burdened with debt and may seek bankruptcy relief. Bankruptcy laws may permit the revocation or renegotiation of contracts between energy producers and MLPs, which could have a dramatic impact on the ability of MLPs to pay distributions to its investors, including the Fund, which in turn could impact the ability of the Fund to pay dividends and dramatically impact the value of the Fund’s investments. Foreign Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States or other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Infrastructure Company Risk.  Infrastructure companies are susceptible to various factors that may negatively impact their businesses or operations, including costs associated with compliance with and changes in environmental, governmental and other regulations, rising interest costs in connection with capital construction and improvement programs, government budgetary constraints that impact publicly funded projects, the effects of general economic conditions throughout the world, surplus capacity and depletion concerns, increased competition from other providers of services, uncertainties regarding the availability of fuel and other natural resources at reasonable prices, the effects of energy conservation policies, unfavorable tax laws or accounting policies and high leverage. Infrastructure companies will also be affected by innovations in technology that could render the way in which a company delivers a product or service obsolete and natural or man-made disasters. Interest Rate Risk.  When interest rates increase, fixed income securities or instruments held by the Fund (which may include inflation protected securities) will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation and changes in general economic conditions. The risks associated with increasing rates are heightened given that interest rates are near historic lows, but may be expected to increase in the future with unpredictable effects on the markets and the Fund’s investments. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions as well as investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. The Fund intends to employ a blend of growth and value investment styles depending on market conditions, either of which may fall out of favor from time to time. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth of earnings potential. Growth companies are often expected by investors to increase their earnings at a certain rate. When these expectations are not met, investors can punish the stocks inordinately even if earnings showed an absolute increase. Also, since growth companies usually invest a high portion of earnings in their business, growth stocks may lack the dividends of some value stocks that can cushion stock prices in a falling market. Growth oriented funds will typically underperform when value investing is in favor. Value stocks are those that are undervalued in comparison to their peers due to adverse business developments or other factors. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to the Fund and shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Liquidity Risk.  The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Master Limited Partnership Risk.  Investments in securities of an MLP involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP. Certain MLP securities may trade in lower volumes due to their smaller capitalizations, and may be subject to more abrupt or erratic price movements and lower market liquidity. MLPs are generally considered interest-rate sensitive investments that generally rely on capital markets to finance capital expenditures and growth opportunities. During periods of interest rate volatility, limited capital markets access and/or low commodities pricing, these investments may not provide attractive returns. Non-Diversification Risk.  The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in fewer issuers than diversified mutual funds. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments. Private Investment in Public Equities Risk.  The Fund may make PIPE transactions. PIPE transactions typically involve the purchase of securities directly from a publicly traded company or its affiliates in a private placement transaction, typically at a discount to the market price of the company’s common stock. In a PIPE transaction, the Fund may bear the price risk from the time of pricing until the time of closing. Equity issued in this manner is often subject to transfer restrictions and is therefore less liquid than equity issued through a registered public offering. For example, the Fund may be subject to lock-up agreements that prohibit transfers for a fixed period of time. In addition, because the sale of the securities in a PIPE transaction is not registered under the Securities Act, the securities are “restricted” and cannot be immediately resold into the public markets. The Fund may enter into a registration rights agreement with the issuer pursuant to which the issuer commits to file a resale registration statement allowing the Fund to publicly resell its securities. However, the ability of the Fund to freely transfer the shares is conditioned upon, among other things, the SEC’s preparedness to declare the resale registration statement effective and the issuer’s right to suspend the Fund’s use of the resale registration statement if the issuer is pursuing a transaction or some other material non-public event is occurring. Accordingly, PIPE securities may be subject to risks associated with illiquid securities. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future. Tax Risk. Tax risks associated with investments in the Fund include but are not limited to the following: MLP Tax Risk.  MLPs are generally treated as partnerships for U.S. federal income tax purposes. Partnerships do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or a change in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in the MLP being required to pay U.S. federal income tax (as well as state and local income taxes) on its taxable income. This would have the effect of reducing the amount of cash available for distribution by the MLP and could result in a reduction in the value of the Fund’s investment in the MLP and lower income to the Fund. To the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in an amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Furthermore, any return of capital distribution received from the MLP may require the Fund to restate the character of its distributions and amend any shareholder tax reporting previously issued. Moreover, a change in current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP investment being treated as a corporation for U.S. federal income tax purposes, which could result in a reduction of the value of the Fund’s investment in the MLP and lower income to the Fund.
