Interest Rate Risks [Member]

Interest Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Changing interest rates may have unpredictable effects on the markets, may result in heightened market volatility and may detract from Portfolio performance. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates.
Duration Risk [Member]

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to the full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.
Municipal Market Risk [Member]

Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Portfolio’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Portfolio invests more of its assets in the municipal securities of a particular state or territory, the Portfolio may be vulnerable to events adversely affecting that state or territory. The Portfolio’s investments in New York municipal securities may be vulnerable to events adversely affecting its economy, including public health crises (including the occurrence of a contagious disease or illness). New York’s economy, while diverse, has a relatively large share of the nation’s financial activities. With the financial services sector contributing more than one-fifth of the state’s wages, the state’s economy is especially vulnerable to adverse events affecting the financial markets such as those that occurred in 2008-2009 and during the COVID-19 pandemic. In addition, as New York’s financial services and professional and business services sectors serve a global market, they can be highly sensitive to global trends. The Portfolio’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.
In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.
The municipal securities issued by Puerto Rico and its government agencies and municipalities may have more risks than those of other U.S. issuers of municipal securities. Puerto Rico continues to face a challenging economic and fiscal environment. If the general economic situation in Puerto Rico persists or worsens, the volatility and credit quality of Puerto Rican municipal securities could continue to be adversely affected, and the market for such securities may deteriorate further.
Inflation Risk [Member]

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Portfolio’s assets can decline as can the value of the Portfolio’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.
Credit Risks [Member]

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.
Tax Risk [Member]

Tax Risk: There is no guarantee that the income on the Portfolio’s municipal securities will be exempt from regular U.S. federal, and if applicable, state income taxes. From time to time, the U.S. Government and the U.S. Congress consider changes in U.S. federal income tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Portfolio by increasing taxes on that income. In such event, the Portfolio’s net asset value (“NAV”) could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax exempt status of municipal bonds could also result in significant shareholder redemptions of Portfolio shares as investors anticipate adverse effects on the Portfolio or seek higher yields to offset the potential loss of the tax deduction. As a result, the Portfolio would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Portfolio’s yield.
Illiquid Investments Risk [Member]

Illiquid Investments Risk: Illiquid investments risk exists when certain investments are or become difficult to purchase or sell. Difficulty in selling such investments may result in sales at disadvantageous prices affecting the value of your investment in the Portfolio. Causes of illiquid investments risk may include low trading volumes, large positions and heavy redemptions of Portfolio shares. Illiquid investments risk may be higher in a rising interest rate environment, when the value and liquidity of fixed-income securities generally decline. Municipal securities may have more illiquid investments risk than other fixed-income securities because they trade less frequently and the market for municipal securities is generally smaller than many other markets.
Derivatives Risks [Member]

Derivatives Risk: Derivatives may be difficult to price or unwind and leveraged so that small changes may produce disproportionate losses for the Portfolio. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, reference rate or index, which could cause the Portfolio to suffer a potentially unlimited loss. Derivatives, especially over-the-counter derivatives, are also subject to counterparty risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable or unwilling to honor its contractual obligations to the Portfolio.
Management Risk [Member]

Management Risk: The Portfolio is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.
Market Risk [Member]

Risk [Text Block]
 
Market Risk: The value of the Portfolio’s assets will fluctuate as the market or markets in which the Portfolio invests fluctuate. The value of the Portfolio’s investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness), terrorism, war, changing interest rate levels, imposition of new or additional tariffs, and regional and global conflicts, that affect large portions of the market.
