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 ended November 30, 2016, the Fund’s portfolio turnover rate was 168% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund invests primarily in the securities of North American energy companies or other companies that benefit from the operations of such North American energy companies (“Beneficiaries”).  North American energy companies and Beneficiaries are defined to include the following:

·
Upstream Companies that explore, develop, complete, drill or produce crude oil, condensate, natural gas and natural gas liquids;

·
Midstream Companies that transport, process, gather and store such commodities and their derivative products such as diesel, gasoline and jet fuel;

·
Downstream Companies that are providers of electric power generation (including renewable energy), transmission and distribution, as well as distributors, marketers and downstream users of energy such as refiners, industrial and petrochemical companies; and

·
North American Energy Beneficiaries that are expected to directly or indirectly benefit from North American energy development, such as companies engaged in oilfield servicing, steel production, manufacturing, engineering, and non-pipeline transportation and logistics companies, such as railroads and shipping companies.

The Adviser attempts to make investments in companies across the North American energy value chain that it believes are, or will be, in a unique position to benefit from changing dynamics, themes, catalysts and opportunities.  Examples include changing market trends, infrastructure constraints, supply/demand imbalances, price differentials, valuation and structural disparities, mergers and acquisitions, restructuring, paradigm shifts and company specific events impacting North American energy companies or their Beneficiaries. The Adviser intends to utilize a flexible strategy to seek exposure to such dynamics, themes, catalysts and opportunities in different proportions at different times. The Fund’s mix of portfolio holdings may change over time based upon the Adviser’s assessment of market and economic conditions.

The Fund seeks to achieve its investment objective by investing typically in common stocks issued by 15 to 40 companies of any capitalization that are publicly traded on an exchange or in the over-the-counter market.  The Fund is non-diversified.

In addition, the Fund may invest in master limited partnerships (“MLPs”).  The Adviser does not anticipate that the Fund will significantly invest in MLPs in all circumstances and market conditions, and the Fund often may not be invested in MLPs at all.  However, in certain circumstances, in anticipation of or response to specific changing dynamics, catalysts, and opportunities, the Fund may invest up to 25% of its total assets in MLPs that the Adviser believes will benefit from such conditions.  MLPs are publicly traded companies organized as limited partnerships or limited liability companies (“LLCs”) and treated as qualified publicly traded partnerships for federal income tax purposes.  Pursuant to tax regulations, the Fund may invest no more than 25% of its total assets in the securities of entities treated as qualified publicly traded partnerships.  The Fund may invest in equity securities issued by MLP affiliates, such as MLP I-Shares and common shares of corporations that own, directly or indirectly.  I-Shares represent an indirect ownership interest in MLP common units issued by an MLP affiliate, which is typically a publicly traded LLC.  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. Issuers of MLP I-Shares are corporations and not partnerships for tax purposes. As a result, MLP I-Shares are not subject to this limitation.

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 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 maturity or issuer, 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) 15% of its total assets in securities of any issuer. The Fund may in certain market conditions seek to hedge investments or realize additional return through the use of short sales. Short sales are transactions in which the Fund sells a security it does not own, in anticipation of a decline in the market value of the security.

The Fund may invest in derivatives which are financial contracts whose values depend on, or are derived from, the values of underlying assets, reference rates, or indices. To manage risk, seek particular portfolio exposure as a substitute for a comparable market position in the underlying exposure, and/or to enhance return (including through the use of leverage), the Fund may invest in derivatives including options, futures, swap contracts and combinations of these instruments. The Fund may invest in futures, options and swap contracts on equity and debt securities, equity and debt indices and commodities (“Commodity Interests”) (i) with aggregate net notional value of up to 100% of the Fund’s net assets, or (ii) for which the initial margin and premiums do not exceed 5% of its net assets, in each case excluding bona fide hedging transactions.

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 in securities that offer attractive total returns over the long-term. The Adviser’s investment process utilizes its unique position and expertise within the energy sector to identify dynamics, catalysts, and opportunities across the entire North American energy value chain and then allocate the Fund’s assets among those securities it believes have the most potential to be impacted by them. The Adviser evaluates selected securities using fundamental analysis and a comparison of quantitative, qualitative, and relative value factors.  In conducting this analysis, the Adviser relies primarily on proprietary models constructed and maintained by the Adviser’s in-house investment team, although it may use research provided by broker-dealers and investment firms.

Borrowing Policy.  The Fund may utilize borrowings for investment purposes and for redemption of Fund shares.  Utilization of such borrowings would generally be short term in nature and within the constraints of the 1940 Act, and will consist of a line of credit from a bank or group of banks.
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 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 North American energy companies and Beneficiaries means that the performance of the Fund will be closely tied to the performance of the energy 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 a concentrated investment focus is that the Fund may be adversely affected if a small number 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 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 MLP I-Shares and 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.  Securities of MLP I-Shares may trade at a market price below that of the MLP affiliate and may be less liquid than securities of their MLP 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).  It is likely that in the near future there will be less governmental action to maintain low interest rates.  Rate increases resulting from this policy change could have a swift and significant negative impact on fixed income securities.  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.

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, Mid-Cap and Small-Cap Companies Risk.  The Fund’s investment in larger companies is 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.  Securities of mid-cap and small-cap companies may be more volatile and less liquid than the securities of large-cap companies.

RIC Compliance Risk.  The Fund intends to elect to be treated, and to qualify each year, as a regulated investment company (“RIC”) under the Internal Revenue Code. To maintain the Fund’s qualification for federal income tax purposes as a RIC, which allows the Fund to avoid paying taxes at regular corporate rates on its income, the Fund must meet certain source-of-income, asset diversification and annual distribution requirements. If for any taxable year the Fund fails to qualify for the special federal income tax treatment afforded to RICs, all of the Fund’s taxable income will be subject to federal income tax at regular corporate rates (without any deduction for distributions to its shareholders).  The resulting increase to the Fund’s expenses would reduce its performance and its income available for distribution to shareholders.  Compliance with the asset diversification test applicable to RICs presents challenges and will require careful, ongoing monitoring. If market valuations cause asset diversification to exceed RIC limitations, incremental investment opportunities will be limited until the Fund is in compliance.  The Fund’s relatively small number of holdings, coupled with its potential investments in MLPs, may present unusual challenges in qualifying each year as a RIC.

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.

Derivatives Risk.  Derivatives can be highly volatile, illiquid and difficult to value, and changes in the value of a derivative held by the Fund may not correlate with the underlying instrument or the Fund’s other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, there are additional risks associated with derivatives trading that are possibly greater than the risks associated with investing directly in the underlying instruments. These additional risks include, but are not limited to liquidity risk, leverage risk and counterparty credit risk.

Leverage Risk. The Fund’s use of leverage through borrowing and short sales may magnify the Fund’s gains or losses.  Because many derivatives have a leverage component, adverse changes in the value or level of the underlying instrument can result in a loss substantially greater than the amount invested in the derivative itself.

Counterparty Credit Risk.  Counterparty credit risk is the risk that a counterparty may default.  If the counterparty defaults, the Fund’s risk of loss will consist of any payments that the Fund is entitled to receive from the counterparty under the agreement.

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.

Short Sale Risk.  In connection with establishing a short position in a security or index, the Fund is subject to the risk that it may not always be able to borrow a security, or to close out a short position at a particular time or at an acceptable price.  If the price of the borrowed security increases between the date of the short sale and the date on which the Fund replaces the security or closes out the position, the Fund will experience a loss.

Asset Segregation Risk.  Under applicable law, the Fund must segregate liquid assets, or engage in other measures, to “cover” open positions with respect to short sales and investments in derivatives. Segregation will not limit the Fund’s exposure to loss, and the Fund may incur investment risk with respect to the segregated assets to the extent that, but for the applicable segregation requirement, the Fund would sell the segregated assets.

Energy Industry Risk.  Companies in the energy industry and their Beneficiaries are subject to many risks that can negatively impact the revenues and viability of companies in this industry.  These risks include, but are not limited to, commodity price volatility risk, supply and demand risk, reserve and depletion risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters.

Portfolio Turnover Risk. A high portfolio turnover rate (100% or more) has the potential to result in the realization and distribution to shareholders of higher capital gains, which may subject you to a higher tax liability.

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 North American energy companies and Beneficiaries the Adviser believes are, or will be, in a unique position to benefit from changing dynamics, catalysts and opportunities across the North America energy value chain;

·
A fund offering the potential for total return;

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

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

·
Simplified tax reporting through a Form 1099.

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.

Bar Chart, Returns for Class Not Offered in Prospectus [Text] rr_BarChartReturnsForClassNotOfferedInProspectus No returns are shown for T Class Shares since T Class Shares were not offered prior to the date of this Prospectus.
[1] No returns are shown for T Class Shares since T Class Shares were not offered prior to the date of this Prospectus. Average annual total returns for T Class Shares would have been substantially similar to those for other classes offered by the Fund because each class of shares would have invested in the same portfolio of securities, and the annual returns would differ only to the extent that the classes have different expenses.
[2] No sales charge is payable at the time of purchase on investments of $1 million or more, although the Fund may impose a Contingent Deferred Sales Charge ("CDSC") of 1.00% on certain redemptions. If imposed, the CDSC applies to redemptions made within 12 months of purchase and will be assessed on an amount equal to the lesser of the initial value of the shares redeemed and the value of shares redeemed at the time of redemption.
[3] Tortoise Capital Advisors, L.L.C. (the "Adviser") has contractually agreed to reimburse the Fund for its operating expenses, in order to ensure that Total Annual Fund Operating Expenses (excluding Rule 12b-1 fees, acquired fund fees and expenses, brokerage commissions, leverage/borrowing interest, interest expense, taxes and extraordinary expenses) do not exceed 1.10% of the average daily net assets of the Fund. Expenses reimbursed by the Adviser may be recouped by the Adviser for a period of thirty-six months following the date on which such reimbursement was made if such recoupment can be achieved without exceeding the expense limit in effect at the time the expense reimbursement occurred and at the time of the recoupment. The Operating Expenses Limitation Agreement will be in effect and cannot be terminated through at least March 31, 2018.
[4] The CDSC applies to redemptions made within 12 months of purchase and will be assessed on an amount equal to the lesser of the initial value of the shares redeemed and the value of shares redeemed at the time of redemption.
