fund, which means it generally invests a greater portion of its assets in the securities of one or more 
issuers and invests overall in a smaller number of issuers than a diversified fund.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The Fund may invest in 
insured municipal securities. Insured municipal securities are covered by insurance policies that guarantee 
the timely payment of principal and interest. The insurance premium costs, however, are typically reflected 
in a lower yield and/or higher price for the insured bond. It is important to note that insurance does 
not guarantee the market value of an insured security, or the Fund&#x2019;s share price or distributions,

finance similar types of projects.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The investment manager selects securities that it believes 
will provide the best balance between risk and return within the Fund&#x2019;s range of allowable investments 
and typically invests with a long-term time horizon. This means it generally holds securities in the 
Fund&#x2019;s portfolio for income purposes, although the investment manager may sell a security at any 
time if it believes it could help the Fund meet its goal. With a focus on income, individual securities 
are considered for purchase or sale based on various factors and considerations, including credit profile, 
risk, structure, pricing, portfolio impact, duration management, restructuring, opportunistic trading 
and tax loss harvesting opportunities.&lt;/p&gt;</oef:StrategyNarrativeTextBlock>

 When interest rates rise, debt security prices generally fall. The opposite is also generally true: 
debt security prices rise when interest rates fall. Interest rate changes are influenced by a number 
of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, 
and supply of and demand for bonds. In general, securities with longer maturities or durations are more 
sensitive to interest rate changes. &lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

 The trading market for a particular security or type of security or other investments in which the Fund 
invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the 
Fund&#x2019;s ability to sell such securities or other investments when necessary to meet the Fund&#x2019;s 
liquidity needs, which may arise or increase in response to a specific economic event or because the 
investment manager wishes to purchase particular investments or believes that a higher level of liquidity 
would be advantageous. Reduced liquidity will also generally lower the value of such securities or other 
investments. Market prices for such securities or other investments may be relatively volatile.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

by adverse political and legislative changes or litigation at the federal or state level. The value of 
municipal bonds is closely tied to the benefits of tax-exempt income to investors. Significant revisions 
of federal income tax laws or regulations revising income tax rates or the tax-exempt character of municipal 
bonds, or even proposed changes and deliberations on this topic by the federal government, could cause 
municipal bond prices to fall. For example, lower federal income tax rates would reduce certain relative 
advantages of owning municipal bonds, and lower state income tax rates could have similar effects. In 
addition, the application of corporate minimum tax rates to financial statement income may have the effect 
of reducing demand for municipal bonds among corporate investors, which may in turn impact municipal 
bond prices.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly 
or unpredictably. The market value of a security or other investment may be reduced by market activity 
or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all 
investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more 
buyers than sellers, prices tend to rise. In addition, the value of the Fund&#x2019;s investments may 
go up or down due to general market or other conditions that are not specifically related to a particular 
issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and 
defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural 
and man-made world events, such as diseases or disasters; financial, political or social disruptions, 
including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could 
result in additional tariffs, trade barriers and/or investment restrictions in certain securities in 
those countries. Any of these conditions can adversely affect the economic prospects of many companies, 
sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert;font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;Ongoing 
or threatened armed conflicts throughout the world have caused and could continue to cause significant 
market disruptions and volatility. The hostilities and sanctions resulting from those hostilities could 
have a significant impact on certain investments of the Fund as well as the Fund&#x2019;s performance 
and liquidity.&lt;/p&gt;</oef:RiskTextBlock>

York municipal securities. Therefore, events in New York are likely to affect the Fund&#x2019;s investments 
and its performance. These events may include economic or political policy changes, tax base erosion, 
unfunded pension and healthcare liabilities, state constitutional limits on tax increases, budget deficits 
and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of 
New York. The same is true of events in other states or U.S. territories, to the extent that the Fund 
has exposure to any other state or territory at any given time.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

 The Fund may invest more than 25% of its assets in municipal securities that finance similar types of 
projects, such as utilities, hospitals, higher education and transportation. A change that affects one 
project, such as proposed legislation on the financing of the project, a shortage of the materials needed 
for the project, or a declining need for the project, would likely affect all similar projects, thereby 
increasing market risk.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

 Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's 
maturity and the Fund must reinvest the proceeds it &lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;receives, 
during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if 
a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment.

debt securities generally falls as inflation increases because the purchasing power of the future income 
and repaid principal is expected to be worth less when received by the Fund. Debt securities that pay 
a fixed rather than variable interest rate are especially vulnerable to inflation risk because variable-rate 
debt securities may be able to participate, over the long term, in rising interest rates which have historically 
corresponded with long-term inflationary trends.&lt;/span&gt;&lt;/p&gt;</oef:RiskTextBlock>

 Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond 
insurance companies. Downgrades and withdrawal of ratings from municipal bond insurers have substantially

the Fund is subject to additional risks including the risk that credit risk may be concentrated among 
fewer insurers and the risk that events involving one or more municipal bond insurers could have a significant 
adverse effect on the value of the securities insured by an insurer and on the municipal markets as a 
whole.&lt;/p&gt;</oef:RiskTextBlock>

custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data 
corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming 
or exchanging shares or receiving distributions. The investment manager has limited ability to prevent 
or mitigate cybersecurity incidents affecting third party service providers, and such third party service 
providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity 
incidents may result in financial losses to the Fund and its shareholders, and substantial costs may 
be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities 
in which the Fund invests are also subject to cybersecurity risks, and the value of these securities 
could decline if the issuers experience cybersecurity incidents.&lt;/p&gt;&lt;p style="margin-top:revert; margin-bottom:revert; font-size:9.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;Because technology is frequently changing, 
new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks 
have not been identified or prepared for, or that an attack may not be detected, which puts limitations 
on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, 
the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents
