Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions or spreads, 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 transaction costs and potentially higher taxes, 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 41.52% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing under normal market conditions at least 80% of its net assets (plus any borrowings for investment purposes) in municipal bonds and other fixed income securities that generate income exempt from regular federal income tax, including the federal alternative minimum tax (“AMT”). The Fund may invest in all types of municipal bonds, including, but not limited to, general obligation bonds and industrial development bonds. The Fund may also invest in asset-backed and mortgage-backed securities, other investment companies, exchange-traded funds (“ETFs”) and the obligations of other issuers that pay interest that is exempt from regular federal income taxes. While the Fund will invest primarily in tax exempt securities, it is possible that up to 20% of the Fund’s total assets may be invested in fixed income securities that generate income that is not exempt from regular federal income tax, including the federal AMT. The Fund invests primarily in investment grade municipal bonds and other types of fixed income securities. Investment grade securities are fixed income securities rated in the top four ratings categories by independent rating organizations such as Standard & Poor’s Ratings Group (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”) or another nationally recognized statistical rating organization (“NRSRO”), or, if unrated, deemed by Rockefeller & Co. LLC, the Fund’s investment adviser (the “Adviser”) to be of comparable quality. While the Fund may invest in securities of any duration, the Adviser anticipates the weighted average duration of the Fund’s portfolio will be more than three years but less than ten years.

The Fund’s investment philosophy is based on a combination of forecasted macro-economic conditions over a six- to twelve-month horizon and is complemented by bottom-up fundamental research. To select investments for the Fund, the Adviser applies the macro-economic analysis by considering securities of any duration which appear to offer the best relative value. The Adviser’s bottom-up research process seeks to identify and avoid issuers which could have significant negative changes in credit quality. In addition to traditional macro-economic and credit analysis, the Adviser may also consider market sentiment and behavioral factors when assessing a security’s relative value and worthiness within a portfolio seeking principal protection and income.

The Fund may also invest in fixed income securities rated below investment grade by an independent rating agency when purchased, including high-yield fixed income securities, and in unrated or split rated securities deemed by the Adviser to be of comparable quality. Such securities are also known as “junk bonds.”

The Fund may invest in securities that are illiquid, thinly traded or subject to special resale restrictions, such as those imposed by Rule 144A promulgated under the Securities Act of 1933, as amended (the “Securities Act”). The Fund’s investments may also include securities that do not produce immediate cash income, such as zero-coupon bonds. The Fund may also purchase and sell securities on a when-issued basis, which involves a commitment by the Fund to purchase or sell securities at a predetermined price or yield, but where payment for the securities is not required until the delivery date.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Before investing in the Fund, you should carefully consider your own investment goals, the amount of time you are willing to leave your money invested, and the amount of risk you are willing to take. Remember, in addition to possibly not achieving your investment goals, you could lose all or a portion of your investment in the Fund over long or even short periods of time. The principal risks of investing in the Fund are:

·	General Market Risk. The value of the Fund’s shares may fluctuate based on the performance of the Fund’s investments and other factors affecting the securities markets generally.

Management Risk. The Adviser’s judgments about the attractiveness, value and potential appreciation of the Fund’s investments may prove to be incorrect and the investment strategies employed by the Adviser in selecting investments for the Fund may not result in an increase in the value of your investment or in overall performance equal to other similar investment vehicles having similar investment strategies.

Municipal Securities Risks. The municipal market is volatile and can be significantly affected by adverse tax, legislative or political changes and the financial condition of the issuers of municipal securities. Because the Fund may invest more than 25% of its total assets in municipal obligations issued by entities located in the same state or the interest on which is paid solely from revenues of similar projects, changes in economic, business or political conditions relating to a particular state or types of projects may have a disproportionate impact on the Fund. Budgetary constraints of local, state, and federal governments upon which the issuers may be relying for funding may also impact municipal securities. In addition, changes in the financial condition of an individual municipal insurer can affect the overall municipal market, and market conditions may directly impact the liquidity and valuation of municipal securities.

Fixed Income Securities Risks. Fixed income securities are or may be subject to interest rate, credit, liquidity, prepayment and extension risks. Interest rates may go up resulting in a decrease in the value of the fixed income securities held by the Fund. Credit risk is the risk that an issuer will not make timely payments of principal and interest. There is also the risk that an issuer may “call,” or repay, its high yielding bonds before their maturity dates. Fixed income securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. Limited trading opportunities for certain fixed income securities may make it more difficult to sell or buy a security at a favorable price or time.

o	Interest Rate Risk. In times of rising interest rates, bond prices will decline. Generally, securities with longer maturities and funds with longer weighted average maturities carry greater interest rate risk.

o	Extension Risk. In times of rising interest rates, prepayments will slow causing portfolio securities considered short or intermediate term to be long-term securities, which fluctuate more widely in response to changes in interest rates than shorter term securities.

o	Liquidity Risk. There may be no willing buyer of the Fund’s portfolio securities and the Fund may have to sell those securities at a lower price or may not be able to sell the securities at all, each of which would have a negative effect on performance.

o	Prepayment Risk. In times of declining interest rates, the Fund’s higher yielding securities will be prepaid and the Fund will have to replace them with securities having a lower yield.

High-Yield Fixed Income Securities Risk. High-yield fixed income securities or “junk bonds” are fixed income securities held by the Fund that are rated below investment grade and are subject to additional risk factors such as increased possibility of default, illiquidity of the security, and changes in value based on public perception of the issuer. Such securities are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities.

Restricted Securities Risk. The Fund may invest in restricted securities (securities with limited transferability under the securities laws) acquired from the issuer in “private placement” transactions. Private placement securities are not registered under the Securities Act, and are subject to restrictions on resale. They are eligible for sale only to certain qualified institutional buyers, like the Fund, and are not sold on a trading market or exchange. While private placement securities offer attractive investment opportunities otherwise not available on an open market, because such securities are available to few buyers, they are often both difficult to sell and to value.

Asset-Backed and Mortgage-Backed Securities Risk. Asset-backed and mortgage-backed securities are subject to risk of prepayment. These types of securities may also decline in value because of mortgage foreclosures or defaults on the underlying obligations. Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.

Government-Sponsored Entities Risk. The Fund invests in securities issued or guaranteed by government-sponsored entities. However, these securities may not be guaranteed or insured by the U.S. Government and may only be supported by the credit of the issuing agency. Securities issued by U.S. Government agencies and instrumentalities have different levels of U.S. Government credit support. Some are backed by the full faith and credit of the U.S. Government, while others are supported by only the discretionary authority of the U.S. Government or only by the credit of the agency or instrumentality. No assurance can be given that the U.S. Government will provide financial support to U.S. Government-sponsored instrumentalities because they are not obligated to do so by law. Guarantees of timely prepayment of principal and interest do not assure that the market prices and yields of the securities are guaranteed nor do they guarantee the net asset value or performance of the Fund, which will vary with changes in interest rates, the Adviser’s success and other market conditions.

Tax Risk. Municipal securities may decrease in value during times when federal income tax rates are falling. The Fund’s investments are affected by changes in federal income tax rates applicable to, or the continuing federal tax-exempt status of, interest income on municipal obligations. Any proposed or actual changes in such rates or exempt status, therefore, can significantly affect the liquidity, marketability and supply and demand for municipal obligations, which would in turn affect the Fund’s ability to acquire and dispose of municipal obligations at desirable yield and price levels. If you are subject to the federal AMT, you may have to pay federal tax on a portion of your distributions from tax-exempt income. If this is the case, the Fund’s net after-tax return to you may be lower. The Fund would not be a suitable investment for investors investing through tax-exempt or tax-deferred accounts.

When‑Issued Securities Risk. The price or yield obtained in a when-issued transaction may be less favorable than the price or yield available in the market when the securities delivery takes place, or that failure of a party to a transaction to consummate the trade may result in a loss to the Fund or missing an opportunity to obtain a price considered advantageous.

·	Zero-Coupon Bond Risk. Zero-coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall.

Other Investment Companies and Exchange Traded Funds Risk. When the Fund invests in other investment companies, including ETFs, it will bear additional expenses based on its pro rata share of the other investment company’s or ETF’s operating expenses, including the potential duplication of management fees. The risk of owning an ETF generally reflects the risks of owning the underlying investments the ETF holds. The market price of an ETF’s shares may trade at a discount to their net asset value, or an active trading market for an ETF’s shares may not develop or be maintained. The Fund also will incur brokerage costs when it purchases and sells ETFs.

Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

Valuation Risk. The prices provided by the Funds’ pricing service or independent dealers or the fair value determinations made by the valuation committee of the Board of Trustees may be different from the prices used by other mutual funds or from the prices at which securities are actually bought and sold. The prices of certain securities provided by pricing services may be subject to frequent and significant change, and will vary depending on the information that is available.
