C000001503 Investment Objective and Strategy
Nuveen Intermediate Duration Municipal Bond Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Nuveen Municipal Trust/ma.
Investment objective
The investment objective of the Fund is to provide you with as high a level of current interest income exempt from regular federal income taxes as is consistent with preservation of capital.
Principal investment strategy
Under normal market conditions, the Fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in municipal bonds that pay interest that is exempt from regular federal personal income tax. These municipal bonds include obligations issued by U.S. states and their subdivisions, authorities, instrumentalities and corporations, as well as obligations issued by U.S. territories (such as Puerto Rico, the U.S. Virgin Islands and Guam) that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund maintains a weighted average effective duration of between 3 and 10 years, and expects to generally maintain a weighted average effective duration of between 4.5 and 7 years.
Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade municipal bonds rated BBB/Baa or higher at the time of purchase by at least one independent rating agency, or, if unrated, judged by the Funds sub-adviser to be of comparable quality. The Fund may invest up to 20% of its net assets in below investment grade municipal bonds, commonly referred to as high yield or junk bonds. The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature. The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (inverse floaters).
Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Funds investments in inverse floaters are designed to increase the Funds income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, and to manage the effective maturity or duration of securities in the Funds portfolio. The Funds sub-adviser uses a value-oriented strategy and looks for higher-yielding and undervalued municipal bonds that offer above-average total return.
The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.
