The Portfolio 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 17% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes the reinvestment of all dividends and distributions in shares of the Portfolio, that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax so that they will qualify to pay “exempt-interest dividends” (“Municipal Securities”). Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg 3‑10 Year Blend (2‑12) Total Return Index, currently 3 to 33 years. The Portfolio’s actual average maturity was 6.61 years as of June 30, 2021. Municipal Securities acquired for the Portfolio will generally be rated in one of the three highest rating categories assigned by one of the major independent rating agencies (“A” or higher by Moodys, or Standard & Poor’s), or are, in the view of the Specialist Manager, deemed to be of comparable quality. The Portfolio is, however, authorized to invest up to 15% of its assets in Municipal Securities that are rated in the fourth highest category and up to 10% of its assets in high yield securities (“junk bonds”). Fixed income securities rated in the fourth highest rating category by a rating agency may have speculative characteristics. The Portfolio is also authorized to invest in securities issued by other investment companies, such as ETFs and closed‑end funds, that invest in Municipal Securities. Also, the Portfolio is authorized to invest up to 20% of its net assets in taxable instruments. The Portfolio may engage in transactions involving instruments such as option or futures contracts in order to hedge against investment risks, seek to efficiently obtain or adjust exposure to certain securities or groups of securities, or otherwise to increase returns. The Portfolio may also write (sell) call options and put options, in order to receive premiums, on individual securities, broad-based market indexes, and/or on substitutes for such indexes, which may include futures contracts or exchange-traded funds. The Portfolio normally writes covered call and put options which have an initial

maturity of up to nine months and that are “out of the money” at the time of initiation such that the call options sold generally will be above the current price level of the index when written and the exercise price of put options sold generally will be below the current price level of the index when written. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

•

Tax Risk – Changes in Federal tax laws or regulations could change the tax‑exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

•

Fixed Income Risk. Investments in fixed income securities may involve the following risks, depending on the instrument involved:

•

Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

•

Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit

price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

•

Call/Prepayment Risk – Municipal securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

•

Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

•

High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. The prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health. Change in market interest rates will also affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

•

Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

•

Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Portfolio’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

•

Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

•

Exchange-Traded Funds Risk – In addition to the risks of investing in other investment companies generally, an investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

•

Risks Associated with Investments in Derivatives

•

General Derivative Risks – Derivatives may be volatile and may involve significant risks. The Portfolio’s exposure to derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other investments. The underlying security, measure or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Normally derivatives involve leverage, which means that their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing the

Portfolio’s losses and reducing the Portfolio’s opportunities for gains. Some derivatives have the potential for unlimited loss, including a loss that may be greater than the amount invested. Derivatives also present default risks if the counterparty to a derivatives contract fails to fulfill its obligations to the Portfolio. Certain derivatives held by the Portfolio may be illiquid, including non‑exchange‑traded or over‑the‑counter derivatives that are linked to illiquid instruments or illiquid markets, making it difficult to close out an unfavorable position. Derivatives also may be more difficult to purchase, sell or value than other instruments. Derivatives risk may be more significant when derivatives are used to enhance return or as a substitute for a cash investment position, rather than solely to hedge the risk of a position held by the Portfolio.

•

Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

•

Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. These rules may: (i) affect whether gains and losses recognized by the Portfolio are treated as ordinary or capital or as short-term or long-term, (ii) accelerate the recognition of income or gains to the Portfolio, (iii) defer losses to the Portfolio, and (iv) cause adjustments in the holding periods of the Portfolio’s securities. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The

Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

•

Options Risk – purchasing and writing put and call options are highly specialized activities and entail greater-than-ordinary investment risks. Investments in options are considered speculative. An option is an agreement that, for a premium payment or fee, gives the option holder (the purchaser) the right but not the obligation to buy (a “call option”) or sell (a “put option”) the underlying security or futures contract (or settle for cash an amount based on an underlying asset, rate or index) at a specified price (the “exercise price”) during a period of time or on a specified date. When the Portfolio writes (sells) an option, it profits if the option expires unexercised, because it retains the premium the buyer of the option paid. However, if the Portfolio writes a call option, it incurs the risk that the market price of the underlying security or futures contract could increase above the option’s exercise price. If this occurs, the option could be exercised and the Portfolio would be forced to sell the underlying security or futures contract at a lower price than its current market value. If the Portfolio writes a put option, it incurs the risk that the market value of the underlying security or futures contract could decrease below the option’s exercise price. If this occurs, the option could be exercised and the Portfolio would be forced to buy the underlying security or futures contract at a higher price than its current market value. When the Portfolio purchases an option, it will lose the premium paid for the option

if the price of the underlying security or futures contract decreases or remains the same (in the case of a call option) or increases or remains the same (in the case of a put option). If an option purchased by the Portfolio were permitted to expire without being sold or exercised, its premium would represent a loss to the Portfolio.

•

Options Writing Strategy Risk – if the underlying index appreciates or depreciates sufficiently over the period to offset the new premium received from the written option on that index, a net loss will result. An index substitute reflects the underlying risks of the index and index substitute options are subject to the same risks as index options. In addition, the value of the index substitute is subject to change as the values of the component securities fluctuate. The performance of the index substitute may not exactly match the performance of the index.

•

Futures Risk – there can be no assurance that price movements in the futures markets will correlate with the prices of the underlying securities positions. Additionally, price distortions could result if investors in the futures markets opt to make or take delivery of the underlying securities rather than engage in closing transactions because such trend might result in a reduction in the liquidity of the futures market. Further, an increase in the participation of speculators in the futures market could cause temporary price distortions.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.
