Strategy Narrative [Text Block]

The fund seeks to achieve its objectives by primarily investing in municipal bonds issued by the state of New York and its agencies and municipalities. Consistent with the fund’s objectives, the fund may also invest in municipal securities that are issued by jurisdictions outside New York. Municipal bonds are debt obligations generally issued to obtain funds for various public purposes, including the construction of public facilities. The fund may also invest in bonds exempt from federal and state taxation that are used to fund private projects.

Under normal circumstances, the fund will invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from regular federal, New York state and New York City income taxes and that do not subject you to federal alternative minimum tax. Investments in derivatives may be counted toward the fund’s 80% investment policy to the extent that such derivatives provide investment exposure to the investments included within the policy or to one or more market risk factors associated with such investments. The fund may also invest up to 20% of its assets in “private activity bonds” whose interest is generally subject to the federal alternative minimum tax. The fund is intended primarily for taxable residents of New York.

The fund will invest primarily in debt securities rated BBB- or better or Baa3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser, or unrated but determined by the fund's investment adviser to be of equivalent quality. The fund may invest up to 10% of its assets in debt securities rated BB+ or below and Ba1 or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. Such securities are sometimes referred to as “junk bonds.”

The fund is nondiversified, which allows it to invest a greater percentage of its assets in any one issuer than would otherwise be the case.

The fund’s assets are managed by a team of portfolio managers. Under this approach, the fund’s portfolio managers will work together to oversee the fund’s entire portfolio.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
