Investment Goal
The Fund's primary goal is providing as high a level of current income
exempt from federal and New Mexico individual income taxes as is
consistent, in the view of the Fund's investment adviser, with preservation
of capital. Its secondary goal is to reduce fluctuations in its net asset
value relative to long-term municipal bond portfolios. No assurance can be
given that these goals will be achieved.
Principal Investment Strategy
The Fund pursues its primary goal by investing principally in a laddered
maturity portfolio of municipal obligations which are issued by the State
of New Mexico, its state agencies and local governments and their agencies
and by United States territories and possessions. The Fund invests in
obligations which are rated as investment grade or, if unrated, which are
issued by obligors which have comparable investment grade obligations
outstanding or which are deemed by the Fund's investment adviser to be
comparable to obligors with outstanding investment grade obligations. The
Fund's portfolio is "laddered" by investing so that some obligations mature
during each of the coming years. The Fund pursues its secondary goal of
reducing share price fluctuations by maintaining a dollar-weighted average
portfolio maturity of normally three to ten years.
Thornburg Investment Management, Inc. actively manages the Fund's
portfolio. Investment decisions are based upon outlooks for interest rates
and securities markets, the supply of debt securities, and analysis of
specific securities. The Fund ordinarily will acquire securities for
investment rather than for realization of gains on market fluctuations.
However, it may dispose of any security before its scheduled maturity to
enhance income or reduce loss, to change the portfolio's average maturity,
or to otherwise respond to current market conditions. The objective of
preserving capital may prevent the Fund from obtaining the highest yields
available.
Additional information about the Fund's investments is available in the
Fund's Annual and Semiannual Reports to Shareholders. In the Fund's
Prospectus you will find a discussion of the market conditions and
investment strategies which significantly affected the Fund's performance
during the last fiscal year. You may obtain copies of the Fund's most
recent Annual and Semiannual Reports and Prospectus at no cost by calling
the Fund's Distributor, Thornburg Securities Corporation, at (800)
847-0200.
Principal Risks
The value of the Fund's shares and its dividends will fluctuate in response
to changes in interest rates. When interest rates increase, the value of
the Fund's investments declines and the Fund's share value is reduced.
This effect is more pronounced for intermediate and longer term obligations
owned by the Fund. During periods of declining interest rates the Fund's
dividends decline. The value of Fund shares also could be reduced if
municipal obligations held by the Fund were downgraded by rating agencies,
or went into default, or if legislation or other government action reduces
the ability of issuers to pay principal and interest when due or changes
the tax treatment of interest on municipal obligations. Because the Fund
invests primarily in obligations originating in New Mexico, the Fund's
share value may be more sensitive to adverse political or economic
developments in that state. A portion of the Fund's dividends may be
subject to the federal alternative minimum tax. The loss of money is a
risk of investing in the Fund, and when you sell your shares they may be
worth less than what you paid for them.
An investment in the Fund is not a deposit in any bank and is not insured
or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.
The Fund is a nondiversified investment company, and means that it may
invest a greater proportion of its assets in the securities of a single
issuer. This may be riskier, because a default or other adverse condition
affecting such an issuer could cause the Fund's share price to decline to a
greater degree.
Past Performance of the Fund
The following information provides some indication of the risks of
investing in the Fund by showing how the Fund's investment results vary
from year to year. The bar chart shows how the annual total returns for
Class A shares have been different in each full year shown. The average
annual total return figures compare Class A share performance to the
Merrill Lynch Municipal (7-12 years) Bond Index, a broad measure of market
performance. No information is presented for Class D shares, which became
available on June 1, 1999. Performance in the past is not necessarily an
indication of how the Fund will perform in the future.
