THORNBURG NEW YORK INTERMEDIATE MUNICIPAL FUND
Prospectus 
June 1, 1997

Thornburg New York Intermediate Municipal Fund is a separate investment 
portfolio ("Fund") offered through this prospectus by Thornburg Investment
Trust.

The Fund is managed by Thornburg Management Company, Inc. (TMC) and offers
Class A shares through this Prospectus, which are sold at net asset value
plus an initial sales charge imposed at the time of sale.  See "Your
Account-Buying Fund Shares," beginning on page 5.

The Fund has the objective of providing, through investment in a
professionally managed portfolio of Municipal Obligations, as high a level of
current income exempt from federal, New York State and New York City personal
income taxes as is consistent, in the view of the Fund's investment adviser,
with preservation of capital.

The Fund will invest primarily in Municipal Obligations originating in New
York State, with the objective of having interest dividends paid to
individual shareholders exempt from individual income taxes imposed by New
York State and New York City.  The Fund will maintain a portfolio having a
dollar-weighted average maturity of normally three to ten years, with the
objective of reducing fluctuations in net asset value relative to long-term
municipal bond portfolios. The Fund will expect lower yields than those
received on long term bond portfolios, while seeking higher yields and
expecting higher share price volatility than mutual funds with short term
portfolios. During temporary periods the portfolio maturity of the Fund may
be reduced for defensive purposes. There is no limitation on the maturity of
any specific security the Fund may purchase, subject to the limitation on the
average maturity of the Fund. There can be no assurance that the Fund's
objectives will be achieved. 

This Prospectus sets forth concisely the information a prospective investor
should know about the Fund before investing. It should be read and retained
for further reference. Additional information about the Fund is contained in
a Statement of Additional Information dated June 1, 1997. The Statement of
Additional Information has been filed with the Securities and Exchange
Commission and may be obtained at no charge by contacting Thornburg
Securities Corporation, 119 East Marcy Street, Suite 202, Santa Fe, New
Mexico  87501, 800-847-0200. This Prospectus incorporates by reference the
Statement of Additional Information.

EXPLANATION OF TABLES

THE INFORMATION IN THE TABLES ABOVE SHOULD NOT BE CONSIDERED A REPRESENTATION
OF PAST OR FUTURE EXPENSES, AND ACTUAL EXPENSES MAY BE GREATER OR LESS THAN
THOSE SHOWN.  The expense figures shown in the tables above are presented to
assist the investor in understanding the various costs that an investor in
the Fund will bear, directly or indirectly.  The Fund's investment adviser
may not assume Fund expenses in the future.

                                                                           1

INVESTMENT OBJECTIVES AND POLICIES  

The primary investment objective of the Fund is to obtain as high a level of
current income exempt from federal personal income tax and New York State and
New York City personal income taxes as is consistent, in the view of TMC,
with preservation of capital. The secondary objective of the Fund is  to
reduce fluctuations in net asset value relative to long-term municipal bond
portfolios, while seeking higher yields and expecting higher share price
volatility than short term portfolios of municipal obligations expect to
have. There is a risk in all investments, however, and there is no assurance
that the Fund's objectives will be achieved. Income otherwise exempt from
federal income tax may be subject to the federal alternative minimum tax, and
distributions from gains attributable to market discount are characterized as
ordinary income for federal income tax purposes. The primary and secondary
investment objectives of the Fund are fundamental policies of the Fund, and
may not be changed without a vote of the Fund's shareholders. 

The Fund will pursue its primary objective by investing in a  portfolio of
investment grade obligations and unrated obligations deemed by the Fund's
investment adviser to be of equivalent quality, which are issued primarily by
New York State and its agencies, New York local governments and agencies, and
by United States territories and possessions ("Municipal Obligations").
Municipal Obligations are discussed below under the caption "Municipal
Obligations," and investment grade ratings are discussed below under the
caption "Securities Ratings and Credit Quality."  

The Fund will seek to achieve its secondary objective of obtaining lower
share price fluctuation than a long-term portfolio and obtaining higher
yields than a short term portfolio by  maintaining a dollar-weighted average
portfolio maturity normally between three and ten years. The Fund may
maintain a portfolio maturity shorter than three years as a defensive
strategy during abnormal market conditions. If your sole objective is
preservation of capital, then the Fund may not be suitable for you because
its net asset value will vary as market interest rates fluctuate, increasing
as interest rates decline and decreasing as interest rates increase. 
Investors whose sole objective is preservation of capital may wish to
consider a high quality money market fund. 

Except to the extent the Fund is invested in temporary investments for
defensive purposes, the objective of the Fund under normal conditions is to
invest 100% of its net assets in Municipal Obligations. As a fundamental
policy which may not be changed without a vote of the Fund's shareholders,
the Fund must  normally invest at least 80% of its net assets in Municipal
Obligations. Under normal conditions the Fund will invest 100%, and as a
matter of fundamental policy, will invest at least 65% of its total assets in
Municipal Obligations which  originate in New York State.  The Fund may
purchase obligations issued by or on behalf of territories or possessions of
the United States and their agencies and instrumentalities. 

The Fund has reserved the right to invest up to 20% of its net assets in
"temporary investments" in taxable securities (of comparable quality to the
above tax-exempt investments) that would produce interest not exempt from
federal income tax. Such temporary investments, which may include repurchase
agreements with dealers, banks or recognized financial institutions that in
the opinion of TMC represent minimal credit risk, may be made due to market
conditions, pending investment of idle funds or to afford liquidity. Such
investments are, like any investment, subject to market  risks and
fluctuations in value. In addition, the Fund's temporary taxable investments
may exceed 20% of its net assets when made for defensive purposes during
periods of abnormal market conditions. The Fund does not expect to find it
necessary to make temporary investments in taxable investments.

MUNICIPAL OBLIGATIONS 

Municipal Obligations are obligations bearing interest exempt from federal
income taxes, which are issued by or on behalf of states, territories and
possessions of the United States and the District  of Columbia, and their
political subdivisions, agencies and  instrumentalities. Municipal
Obligations include notes (including tax-exempt commercial paper), bonds,
municipal leases and  participation interests in these obligations. Interest
on Municipal Obligations may be subject to the alternative minimum tax or
state income taxes. See "Federal Taxes." 

The yields on Municipal Obligations are dependent on a variety of factors,
including the condition of the general money market and the Municipal
Obligation market, the size of a particular offering, the maturity of the
obligation and the rating of the issue. The  market value of outstanding
Municipal Obligations will vary with changes in prevailing interest rate
levels and as a result of changing  evaluations of the ability of their
issuers to meet interest and  principal payments. Variations in market value
of Municipal Obligations held in the Fund's portfolio arising from these or
other factors will cause changes in the net asset value of the Fund's shares.
See "Net Asset Value."  Municipal Obligations often grant the issuer the
option to pay off the obligation prior to its final maturity. Prepayment of
Municipal Obligations may reduce the expected yield on invested
funds, the net asset value of the Fund, or both if interest rates have
declined below the level  prevailing when the obligation was purchased. If
interest rates have declined, reinvestment of the proceeds from the
prepayment of Municipal Obligations may result in a lower yield to the Fund.
In addition, the federal income tax treatment of gains from market discount
as ordinary income may increase the price volatility of Municipal
Obligations. 

Obligations of issuers of Municipal Obligations are subject to the provisions
of bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the United States Bankruptcy Code. In addition, the
obligations of such issuers may become subject to the laws enacted in the
future by Congress, state legislatures or referenda extending the time for
payment  of principal or interest, or imposing other constraints upon
enforcement of such obligations or upon municipalities to levy taxes. There
is also the possibility that, as a result of legislation or other conditions,
the power or ability of any issuer to pay, when due, the principal of and
interest on its Municipal Obligations may be materially and adversely
affected.


VARIABLE RATE SECURITIES; INVERSE FLOATERS; AND DEMAND INSTRUMENTS 

The Fund may purchase variable rate Municipal Obligations. These variable
rate securities bear rates of interest that are adjusted periodically
according to formulas intended to reflect market rates of interest, and these
may include "inverse floaters," whose rates vary inversely with changes in
market rates of interest. The values of inverse floaters will tend to be more
volatile than fixed rate municipal securities having similar credit quality,
redemption  provisions, and maturity. The Fund will not invest more than 10%
of its total assets in securities whose rates vary inversely with changes in
market rates of interest. The Fund also may purchase variable rate demand
instruments and also may purchase fixed rate municipal demand instruments
either in the public market or privately from banks, insurance companies and
other financial institutions. These instruments provide for periodic
adjustment of the interest rate paid to the holder. The "demand" feature
permits the holder to demand payment of principal and interest prior to the
final stated maturity, either from the issuer or by drawing on a bank letter
of credit, a guarantee or insurance issued with respect to the instrument.

                                                                          3
<PAGE>     4

MUNICIPAL LEASES 

The Fund may invest in Municipal Leases. These obligations are used by state
and local governments to acquire a wide variety of equipment and facilities.
Many such obligations include  "non-appropriation" clauses which provide that
the governmental issuer has no obligation to make payments unless money is 
appropriated for that purpose. If an issuer stopped making payment on a
Municipal Lease held by the Fund, the Lease would lose some or all of its
value.  Often, the Fund will not hold the obligation directly, but will
purchase a "participation interest" in the  obligation, which gives the Fund
an undivided interest in the underlying Municipal Lease. Some Municipal
Leases may be  illiquid under certain circumstances, and TMC will evaluate
the liquidity of each Municipal Lease upon its acquisition by the Fund and
periodically while it is held. 

SECURITIES RATINGS AND  CREDIT QUALITY 

The Fund's assets will normally consist of (1) Municipal Obligations
(including Municipal Leases) or participation interests therein that are
rated at the time of purchase within the four  highest grades by Moody's
Investors Service, Inc. ("Moody's"), Fitch Investors Service ("Fitch"), or
Standard & Poor's Corporation ("S&P"), (2) Municipal Obligations (including
Municipal Leases) or participation interests therein that are not rated by a
rating agency, but are issued by obligors that either have other  comparable
debt obligations that are rated within the four highest grades (Baa or BBB or
better) by Moody's or S&P or Fitch or, in the case of obligors whose
obligations are unrated, are deemed by TMC to be comparable with issuers
having such debt ratings, and (3) cash. Securities rated in the described
categories are described as "investment grade," and are regarded as having a
capacity to pay interest and repay principal that varies from "extremely
strong" to "adequate." According to S&P, for example, BBB bonds normally
exhibit adequate protection parameters, although adverse economic conditions
or other changes are more likely to lead to a weakened capacity compared to
higher rated  categories, and AAA bonds exhibit extremely strong capacity.
Securities rated Baa are regarded by Moody's as having some speculative
characteristics. Securities rated BBB by Fitch are  considered to have
adequate capacity, although adverse changes in economic conditions and
circumstances are more likely to have an adverse impact than for higher rated
categories. Please see the Statement of Additional Information for detailed
descriptions of these ratings. 

Investments in Municipal Obligations may also include (i) variable rate
demand instruments that are rated within the two highest grades of a rating
agency or, if unrated, are deemed by TMC to be of high quality and minimal
credit risk, (ii) tax-exempt commercial paper that is rated within the two
highest grades of a rating agency, and (iii) municipal notes that are rated
within the two highest grades of a rating agency or, if unrated, are deemed
by TMC to be of comparable quality to such rated municipal notes. To the
extent that unrated Municipal Obligations may be less  liquid, there may be
somewhat greater risk in purchasing unrated Municipal Obligations than in
purchasing comparable, rated Municipal Obligations. If the Fund experienced
unexpected net redemptions, it could be forced to sell such unrated Municipal
Obligations at disadvantageous prices without regard to the Obligations'
investment merits, depressing the Fund's net  asset value and possibly
reducing the Fund's overall investment performance. 

Credit ratings do not reflect the risk that market values of Municipal
Obligations will fluctuate with changes in interest rates, and credit rating
firms may fail to change credit ratings in a timely fashion to reflect events
subsequent to initial ratings. Accordingly, in addition to using credit
rating information, TMC subjects each issue under consideration for
investment to its own credit analysis in an effort to assess the issuer's
financial soundness. This analysis is performed on a continuing basis for all
issues held by the Fund, and TMC may determine to dispose of portfolio
securities upon a change in ratings or adverse events or market conditions
not reflected 

4

<PAGE>     5

in ratings. TMC evaluates the credit quality of unrated Municipal Obligations
purchased by the Fund under the general supervision of its Trustees, and
determines the equivalency of unrated obligations to rated obligations.  


WHEN-ISSUED TRANSACTIONS 

The Fund may purchase Municipal Obligations on a  "when-issued" or delayed
delivery basis, which means that the securities are not delivered until a
future date that may be as many as 45 days after the Fund has agreed to the
purchase. These  transactions may involve an element of risk because the
value of the securities is subject to market fluctuation, no interest accrues
to the purchaser before delivery of the securities, and at the time of
delivery the market value may be less than cost. When the Fund agrees to
purchase Municipal Obligations on a "when-issued" basis, it will maintain
high grade liquid debt assets equal in value to the purchase price of the
"when-issued" securities in a  segregated account with its custodian bank.  

INVESTMENT RESTRICTIONS 

The Fund is subject to the restriction that it will not  purchase any
investment or enter into any transactions if, as a result, more than 10%
of the Fund's net assets will be illiquid investments.  The Fund is subject
to other investment restrictions, which are described in the Fund's Statement
of Additional Information. 

SPECIAL CONSIDERATIONS AFFECTING THE FUND

The Fund is a  non-diversified series of Thornburg Investment Trust, and
therefore may invest more than five percent of its portfolio assets in the
securities of a single issuer, provided that it may not  purchase any
security (other than securities issued or guaranteed as to principal or
interest by the United States or its instrumentalities) if, as a result, more
than five percent of the Trust's total assets would be invested in securities
of a single issuer.  Because the Fund will purchase Municipal Obligations
originating primarily from within New York, an investment in the Fund may be
riskier than an investment in a portfolio of Municipal Obligations from
throughout the United States.  

New York State has a diverse economy, growing personal income, and strength
in consumer spending and tourism, but has not participated uniformly with
other regions in the national economic recovery of 1991 through 1997. 
Although employment growth is weak, growth in personal income has resulted in
some increase in government revenues.  The state, however, has not taken
advantage of revenue increases to reduce the state's substantial accumulated
deficits and establish reserves.  Consequently the financial stability and
credit of the state and many of its agencies and political subdivisions could
be vulnerable to consumer spending reductions, national economic weakness or
changes in federally mandated programs.  The state's chronic budget
difficulties, while helped recently by some spending reductions, also may be
aggravated by tax cuts unless further spending reductions are implemented or
the state's economy improves. 

YOUR ACCOUNT -
BUYING FUND SHARES IN GENERAL 

The Fund currently offers only one class of shares, but may offer other
classes of shares in the future.  Each of the Fund's shares represents an
equal undivided interest in the Fund's assets.  

Shares are sold subject to a sales charge which is deducted at the time you
purchase your shares.  TSC deducts the sales charge shown in the table on
page 6 and invests the balance of your investment at net asset value.

Shares of the Fund may be purchased through investment dealers, brokers or
agents ("financial advisors") who have  agreements with the Fund's
distributor, Thornburg Securities Corporation (TSC), or through TSC in those

                                                                          5
<PAGE>     6

states where TSC is registered. Shares of the Fund are or will be available
only in New York State and may be made available in certain other states
where the Fund is qualified for sale. All orders are subject to acceptance by
the Fund, and the Fund and TSC reserve the right to refuse any order in whole
or in part.

NET ASSET VALUE 

When you purchase shares, the price is based on the net asset value (NAV)
next determined after receipt of your order.  The net asset value is the
value of a share, and is computed by adding the value of investments, cash
and other assets, subtracting liabilities, and then dividing by the number of
shares outstanding.  The value of investments is determined by an independent
pricing service.  Share price is normally calculated at 4:00 p.m. Eastern
time on each day the New York Stock Exchange is open for business.

BUYING SHARES 

When you buy shares the sales charge applicable to your investment is
deducted from the price you pay and the balance is invested at NAV. The sales
charge is shown in the table below.

<F*> No sales charge will be payable at the time of purchase on investments
     of $1 million of more made by a purchaser.  A contingent deferred sales
     charge will be imposed on these investments in the event of a share
     redemption within one year following the share purchase at the rate of
     1/2 of 1%.  In determining whether such a sales charge is payable and
     the amount of any charge, it is assumed that shares not subject to the
     charge are the first redeemed followed by other shares held for the
     longest period of time.  The applicability of these charges will be
     unaffected by transfers of registration.  TSC or TMC intend to pay a
     commission of up to 1/2 of 1% to dealers who place orders of $1 million
     or more for a single purchaser. 

     At certain times, for specific periods, TSC may reallow up to the full 
     sales charge to all dealers who sell Fund shares.  These "full 
     reallowances" may be based upon the dealer reaching specified minimum 
     sales goals.  TSC will reallow the full sales charge only after
     notifying all dealers who sell Fund shares.  During such periods,
     dealers may be considered underwriters under securities laws.  TMC or
     TSC also may pay additional cash or non-cash compensation to dealer
     firms which have selling agreements with TSC.  Those firms may pay
     additional compensation to financial advisors who sell Fund shares. 
     Non-cash compensation may include travel and lodging in connection 
     with seminars or other educational programs.

</TABLE>

LETTERS OF INTENT.  If you intend to invest, over the course of 13 or fewer
months, an amount of money that would qualify for a reduced sales charge if
it were made in one investment, you can qualify for the reduced sales charge
on the entire amount of your investment by signing a "Letter of Intent"
(LOI). Each investment you make during the 13 months will be charged the
reduced sales commission applicable to the amount stated in your LOI. You do
not have to reach the goal you set. If  you don't, you will have to pay the
difference between the sales charge you would have paid and the sales charge
you did pay. You may pay this amount directly to TSC, or TSC will redeem a
sufficient number of your shares in the Fund to obtain the difference.

RIGHTS OF ACCUMULATION. Each time the value of your account plus the amount
of any new investment passes one of the breakpoints illustrated in the table
on page 6, the amount of your new investment in excess of the breakpoint
will be charged the reduced sales charge applicable to that range. 

WAIVERS. You may purchase shares of the Fund with no sales charge if
you notify TSC or the Fund's transfer agent, NFDS, at the time you purchase
shares that you belong to one of the categories below. If you do not provide
such notification at the time of purchase, your purchase will not qualify for
the waiver of sales charge.

STREET NAME OWNERSHIP OF SHARES
 
Some securities dealers offer to act as owner of record of Fund shares as a
convenience to investors who are clients of those  firms and shareholders of
the Fund. Neither the Fund nor the Transfer Agent can be responsible for
failures or delays in crediting shareholders for dividends or redemption
proceeds, or for delays in reports to shareholders if a shareholder elect s
to hold Fund shares in street-name through a brokerage firm account rather
than directly in the shareholder's own name. Further, neither the Fund nor
the Transfer Agent will be responsible to the investor for any loss to the
investor due to the brokerage firm's failure, its loss of property or funds,
or its acts or omissions. Prospective investors are urged to confer with
their financial advisor to learn about the different options available for
owning mutual fund shares. You may receive share certificates or hold shares
in your name with the Transfer Agent upon request. 

SELLING FUND SHARES 

You can withdraw money from your Fund account at any time by redeeming some
or all of your shares (by selling them back to the Fund or by selling the
shares through you r financial advisor). Your shares will be purchased by the
Fund at the next share price (NAV) calculated after your order is received in
proper form. The amount of the CDSC, if any, will be deducted and the
remaining proceeds sent to you. No CDSC is imposed on the amount by which the
value of a share may have appreciated. Similarly, no CDSC is imposed on
shares obtained through reinvestment of dividends or capital gains. Shares
not subject to a CDSC will be redeemed first. Share price is normally
calculated at 4 p.m. Eastern time. 

To sell shares in an account, you may use any of the methods described on the
following page. 

If you are selling some but not all of your shares, leave at least $1,000
worth of shares in the account to keep it open. 

CERTAIN REQUESTS MUST INCLUDE A SIGNATURE GUARANTEE. It is designed to
protect you and your Fund from fraud. Your request must be made in writing
and include a signature guarantee if any of the following situations apply: 

 * You wish to redeem more than $10,000 worth of shares, 
 * Your account registration has changed within the last 30 days, 
 * The check is being mailed to a different address than the one on your
   account (record address), 
 * The check is being made payable to someone other than the account owner,
   or 
 * The redemption proceeds are being transferred to a Thornburg account with
   a different registration. 

You should be able to obtain a signature guarantee from a bank, broker
dealer, credit union (if authorized under state law), securities exchange or
association, clearing agency, savings association or participant in the
Securities Transfer Agent Medallion Program (STAMP). A notary public cannot
provide a signature guarantee. 

TELEPHONE REDEMPTION. If you completed the telephone redemption section of
your application when you first purchased your shares, you may easily redeem
shares of the Fund by telephone simply by calling a Fund Customer Service
Representative.  Money can be wired directly to the bank account designated
by you on the application or sent to you in a check. The Fund's Transfer
Agent may charge a fee for a bank wire. This fee will be deducted from the
amount wired.

If you did not complete the telephone redemption section of your application,
you may add this feature to your account by calling the Fund for a telephone
redemption application. Once you receive it, please fill it out, have it
signature guaranteed and send it to:

The Fund, TSC, TMC and the Fund's Transfer Agent are not responsible for, and
will not be liable for, the authenticity of withdrawal instructions received
by telephone or the delivery or transmittal of the redemption proceeds if
they follow instructions communicated by telephone that they reasonably
believe to be genuine. By electing telephone redemption you are giving up a
measure of security you otherwise may have by redeeming shares only with
written instructions, and you may bear the risk of any losses resulting from
telephone redemption. The Fund's Transfer Agent will attempt to implement
reasonable procedures to prevent unauthorized transactions and the Fund or
its Transfer Agent could be liable if these procedures are not employed.
These procedures will include recording of telephone transactions, providing
written confirmation of such transactions within 5 days, and requesting
certain information to better confirm the identity of the caller at the time
of the transaction.

INVESTOR SERVICES 
 
Thornburg Funds provide a variety of services to help you manage your
account. 

Information Services 

Thornburg Funds' telephone representatives are available Monday through
Friday from 9:30 am to 6:30 pm Eastern time. Whenever you call, you can speak
with someone equipped to provide the information or service you need. 

Thornburg Funds' Audio Response system is available 24 hours a day, 365 days
a year. This computerized system gives you instant access to your account
information and up-to-date figures on all of the Thornburg Funds. 

Statements and reports that Thornburg Funds send to you include the
following: 
 * Account statements after every transaction affecting your account 
 * Monthly account statements 
 * Financial reports (every six months) 
 * Cost basis statement (at the end of any year in which you redeem shares) 

TRANSACTION SERVICES 

Automatic Investment Plan. One easy way to pursue your financial goals is to
invest money regularly. Thornburg Funds let you transfer as little as $100
from your bank account into your Fund account on a weekly, monthly or
quarterly basis, automatically. Because the Fund's Automatic Investment Plan 
has a lower minimum than a regular purchase, it is an ideal way for beginning
investors to invest in the Fund.  

While regular investment plans do not guarantee a profit and will not protect
you against loss in a declining market, they can be an excellent way to
invest for retirement, a home, educational expenses, and other long-term
financial goals. Call 1-800-847-0200 and speak to a Fund Customer Service
Representative for more information.  

Exchange Privilege. You may exchange Class A shares of any other Thornburg
Fund for shares of the Fund.  

If you are exchanging from the Fund covered by this prospectus into another
Thornburg Fund, you may (i) have to pay the difference between the front end
sales charge you paid on the Fund out of which you are exchanging and the
front end sales charge applicable to the Fund into which you are exchanging;
or (ii) you may qualify for a reduced sales charge or no sales charge on that
Fund. Please consult the exchange an d reinvestment privilege information in
the Prospectus of the other Thornburg Fund. 

Note that exchanges out of the Fund may have tax consequences for you. For
details on policies and restrictions governing exchanges, including
circumstances under which a shareholder's exchange privilege may be suspended
or revoked, see page 16.

Systematic withdrawal plans let you set up periodic redemptions from your
account. Because of the sales charge on shares of the Fund, you may
not want to set up a systematic withdrawal plan during a period when you are
buying shares on a regular basis. 

                                                                         11

SHAREHOLDER AND ACCOUNT POLICIES

Dividends, Capital Gains, and Taxes 
The Fund distributes substantially all of its net income and realized
capital gains, if any, to  shareholders each year. The Fund declares its net
investment income daily and distributes it monthly. The Fund will distribute
net realized capital gains, if any, at least annually. Capital gain
distributions normally will be declared and payable in December. 

Distribution Options 
The Fund earns interest from bonds and other investments.
These are passed along as dividend distributions. The Fund realizes capital
gains whenever it sells securities for a higher price than it paid for them.
These are passed along as capital gain distributions. 

When you open an account, specify on your application how you want to receive
your distributions. The Fund offers four options, (which you can change at
any time). 

Dividends 
1. Reinvestment Option. Your dividend distributions will be automatically
   invested in additional shares of your Fund. If you do not indicate a
   choice on your application, you will be assigned this option. You may also
   instruct the Fund to invest your dividends in the shares of any other
   Thornburg Fund. 

2. Cash Option. You will be sent a check for your dividend distributions.
   Cash distribution checks are normally mailed on the third business day
   after the month-end. 

Capital Gains
1. Reinvestment Option. Your capital gain distributions, if any, will be
   automatically reinvested in additional shares of the Fund. If you do not
   indicate a choice on your application, you will be assigned this option.
   You may also instruct the Fund to re invest your capital gain
   distributions in shares of any other Thornburg Fund. 

2. Cash Option. You will be sent a check for any capital gain distributions.

Shares of any Thornburg Fund purchased through reinvestment of dividend and
capital gain distributions are not subject to sales charges or contingent
deferred sales charges. 

Turnover and Capital Gains 

The Fund does not intend to engage in short-term trading for profits.
Nevertheless, when the Fund believes that a security will no longer
contribute towards reaching its goal, it will normally sell that security. 

When the Fund sells a security at a profit it realizes a capital gain. When
it sells a security at a loss it realizes a capital loss.  The Fund must, by
law, distribute capital gains, net of any losses, to its shareholders.
Whether you reinvest your capital gain distributions or take them in cash,
the distribution is taxable. 

To minimize taxable capital gain distributions, the Fund will realize
capital losses, if available, when, in the judgment of the portfolio manager,
the integrity and income generating aspects of the portfolio would be
unaffected by doing so.

TAXES 

Federal Taxes 

The Fund intends to qualify under Subchapter M of the Internal Revenue Code
(the "Code ") for tax treatment as a regulated investment company, and the
Fund intends to continue its qualification so long as qualification is in the
best interests of the shareholders.  This tax treatment relieves the Fund
from paying federal income tax on income which is currently distributed to
its shareholders.  The Fund also intends to satisfy conditions that will
enable it to designate distributions from the interest income generated by
its investments in Municipal Obligations, which are exempt from federal
income tax when received by the Fund, as Exempt Interest Dividends.
 
Individual shareholders receiving Exempt Interest Dividends  will not be
subject to federal income tax on the amount of such dividends, except to the
extent the alternative minimum tax may be imposed. 

The Fund's counsel, White, Koch, Kelly & McCarthy, Professional Association,
has not made and normally will not make any review of the proceedings
relating to the issuance of the Municipal Obligations or the basis for any
opinions issued in connection therewith. In the case of certain Municipal
Obligations, federal tax exemption is dependent upon the issuer (and other
users) complying with certain ongoing requirements. There can be no assurance
that the issuer (and other users) will comply with these requirements, in
which event the interest on such Municipal Obligations could be determined to
be taxable, in most cases retroactively from the date of issuance. Certain
matters under the Code, including certain exceptions to the foregoing, are
discussed more specifically below. 

Distributions by the Fund of net interest income received from certain
temporary investments (such as certificates of deposit, corporate commercial
paper and obligations of the United States government, its agencies and
instrumentalities) and net short-term capital gains realized by the Fund, if
any, will be taxable to shareholders as ordinary income whether received in
cash or additional shares. Distributions to shareholders will not qualify for
the dividends received deduction for corporations. Any net long-term capital
gains realized by the Fund, whether or not distributed, will be taxable to
shareholders as long-term capital gains regardless of the length of time
investors have held their shares, although gains attributable to market  
discount on portfolio securities will be characterized as ordinary income.
Each year the Fund will, where applicable, mail to shareholders information
on the tax status of dividends and distributions, including the respective
percentages of tax-exempt and taxable income. The exemption of interest
income for federal income tax purposes does not necessarily result in an
exemption under the income or other tax laws of any state or local taxing
authorities. (See "State Taxes," below). Shareholders are advised to consult
their own tax advisers for more detailed information concerning the federal,
state and local taxation of the Fund and the income tax consequences to its
shareholders. 

The Code treats interest on certain Municipal Obligations which are private
activity bonds under the Code as a preference item for purposes of the
alternative minimum tax on individuals and corporations. The Fund may
purchase without limitation private activity bonds the interest on which is
subject to treatment under the Code as a preference item for purposes of the
alternative minimum tax on individuals and corporations, although the
frequency and amounts of these purchases are presently uncertain. Some
portion of Exempt Interest Dividends may, as a result of these purchases, be
treated as a preference item for purposes of the alternative minimum tax on
individuals and corporations. Shareholders are advised to consult their own
tax advisers as to the extent and effect of this treatment. 

                                                                         13

New York State and New York City Personal Income Taxes 

Exempt interest dividends paid by the Fund in cash or additional shares, and
attributable to interest received by the Fund on Municipal Obligations
originating in New York, will be exempt from New York State and New York City
personal income taxes.  Capital gains distributions and dividends
attributable to market discount and interest not received on New York
Municipal Obligations will be subject to New York State and New York City
personal income taxes.  Any gain realized on redemption of Fund shares also
will be subject to these taxes. 

SERVICE PLAN

The Fund has adopted a Service Plan under which TMC makes payments to
securities dealers and other financial institutions and organizations to
obtain various shareholder related services. The Service Plan permits the
Fund to reimburse TMC for these payments at annual rates up to .25% of its
net assets. No assets of any class of the Fund will be used to reimburse
expenses attributable to any other class of the same, or any other Fund.

The Glass-Steagall Act prohibits certain banks from underwriting mutual fund
shares. The Fund does not believe that this prohibition will apply to the
commissions described beginning on page 7 or to the plan described above.
However, no assurance can be given that the Glass-Steagall Act will not be
interpreted so as to prohibit these arrangements. In that event, the ability
of the Fund to market its shares could be impaired to a small extent. In
addition, state securities laws on this issue may differ from interpretations
of federal law, and banks and financial institutions may be required to
register as dealers pursuant to state law. 
 
TRANSACTION DETAILS 

The Fund is open for business each day the New York Stock Exchange (NYSE) is
open. The Fund normally calculates its NAV (and offering price for shares) as
of the close of business of the NYSE, normally 4 p.m. Eastern time.  The
Fund's assets are valued on the basis of valuations obtained from independent
pricing services. 

When you sign your account application, you will be asked to certify that
your Social Security or taxpayer identification number is correct and that
you are not subject to 31%  backup withholding for failing to report income
to the IRS. If you violate IRS regulations, the IRS can require the Fund to
withhold 31% of your taxable distributions and redemptions. 

You may initiate many transactions by telephone. Note that he Fund will not
be responsible for any losses resulting from unauthorized transactions if it
follows reasonable procedures designed to verify the identity of the caller.
The Fund will request personalized security codes or other information, and
may  also record calls. You should verify the accuracy of your confirmation
statements immediately after you receive them. If you want the ability to
redeem and exchange by telephone, fill in the appropriate section of the
application. If you have an existing account to which you wish to add this
feature, call the Fund for a telephone redemption application. If you are
unable to reach the Fund by phone (for example, during periods of unusual
market activity), consider placing your order by mail or by using your
financial advisor. 

The Fund reserves the right to suspend the offering of shares for a period of
time. The Fund also reserves the right to reject any specific purchase
order, including certain purchases by exchange. See "Exchange Restrictions"
on page 16. Purchase orders may be refused if, in TMC's opinion, they would
disrupt management of the Fund.  

When you place an order to buy shares, your order will be processed at the
next share price calculated after your order is received. If you open or add
to your account yourself rather than through your financial advisor please
note the following:

14

<PAGE>     15

 * All of your purchases must be made in U.S. dollars and checks must be
   drawn on U.S. banks. 
 * The Fund does not accept cash. 
 * If your check does not clear, your purchase will be cancelled and you
   could be liable for any losses or fees the Fund or its Transfer Agent has
   incurred. 

When you buy shares of the Fund or sell them through your financial advisor,
you may be charged a fee for this service. Please read your financial
advisor's program materials for any additional procedures, service features
or fees that may apply. 

Certain financial institutions that have entered sales agreements with TSC
may enter confirmed purchase orders on behalf of customers by phone, with
payment to follow no later than the time when the Fund is priced on the
following business day. If payment is not received by that time, the
financial institution could be held liable for resulting fees or losses. 

When you place an order to sell shares, your shares will be sold at the next
NAV calculated after your request is received and accepted. (Except that a
CDSC of 1/2 of 1% will be deducted from redemptions of shares within one year
of purchase where no sales charge was imposed on the purchase because it
exceeded $1,000,000). Note the following: 

 * Consult your financial advisor for procedures governing redemption through
   his or her firm. 
 * If you redeem by mail the proceeds will normally be mailed to you on the
   next business day, but if making immediate payment could adversely affect
   your Fund, it may take up to 7 days to pay you. 
 * Telephone redemptions over the wire generally will be credited to your
   bank account on the business day after your phone call. 
 * The Fund may hold payment on redemptions until it is reasonably satisfied
   that investments previously made by check have been collected, which can
   take up to 15 business days. 
 * Redemptions may be suspended or payment dates postponed when the NYSE is
   closed (other than weekends or holidays), when trading on the NYSE is
   restricted, or as permitted by the SEC. 
 * To the extent consistent with state and federal law, the Fund may make
   payments of the redemption price either in cash or in kind. The Fund has
   elected to pay in cash all requests for redemption by any shareholder.
   It may, however, limit such cash in respect to each shareholder during
   any 90 day period to  the lesser of $250,000 or 1% of the net asset value
   of the Fund at the beginning of such period. This election has been made
   pursuant to Rule 18f-1 under the Investment Company Act of 1940 and is
   irrevocable while the Rule is in effect unless the Securities and Exchange
   Commission, by order, permits its withdrawal. In the case of a redemption
   in kind, securities delivered in payment for shares would be valued at the
   same value assigned to them in computing the net asset value per share of
   the Fund. A shareholder receiving such securities would incur  brokerage
   costs when selling the securities.

EXCHANGE RESTRICTIONS

As a shareholder you have the privilege of exchanging shares of the Fund for
Class A shares of other Thornburg Funds.  However, you should note the
following:

 * The Fund you are exchanging into must be registered for sale in your
   state. 
 * You may only exchange between accounts that are registered in the same
   name, address, and taxpayer identification number. 
 * Before exchanging into a Fund, read its prospectus.
 * If you exchange shares into a Fund with a higher sales charge, you may
   have to pay the percentage-point difference between that Fund's sales
   charge and any sales charge you have previously paid in connection with
   the shares you are exchanging. For example, if you had already paid a
   sales charge of 3.5% on your shares and you exchange them into a Fund with
   a 4.5% sales charge, you would pay an additional 1% sales charge.  
 * Exchanges may have tax consequences for you. 
 * Because excessive trading can hurt performance and shareholders, each
   Thornburg Fund reserves the right to temporarily or permanently terminate
   the exchange privilege of any investor who makes more than four exchanges
   out of a Fund in any calendar year. Accounts under common ownership or
   control, including accounts with the same taxpayer identification number,
   will be counted together for purposes of the four exchange limit. 
 * The Fund reserves the right to refuse exchange purchases by any person or
   group if, in TMC's judgement, the Fund would be unable to invest the money
   effectively in accordance with  its investment objective and policies, or
   would otherwise potentially be adversely affected. 
 * Your exchanges may be restricted or refused if a Fund receives or
   anticipates simultaneous orders affecting significant portions of the 
   Fund's assets. In particular, a pattern of exchanges that coincide with a
   "market timing" strategy may be disruptive to a Fund.  
 
Although the Fund will attempt to give prior notice whenever it is reasonably
able to do so, it may impose these restrictions at any time. Each of the
Thornburg Funds reserves the right to terminate or modify any exchange
privilege in the future. 
 
PERFORMANCE 
 
YIELD COMPUTATION AND TOTAL RETURN 
 
The Fund may quote its yields and returns in reports, sales literature and
advertisements.  Any return quoted should not be considered a representation
of the return in the future since return figures are based upon historical
earnings. Actual performance will vary.  
 
Current yield quotations will include a standardized calculation which
computes yield for a 30-day or one-month period by dividing the Fund's net
investment income per share during the period by the maximum offering price
on the last day of the period and annualizing the result. Provided that any
such quotation is also accompanied by the standardized calculation referred
to above, the Fund also may quote non-standardized yields for a specified
period by dividing the net investment income per share of the Fund for that
period by either the Fund's average public offering price per share for that
same period or the offering price per share on the first or last day of the
period and annualizing the result. The primary differences between the yield
calculations obtain ed using the standardized performance measure and any
non-standardized performance measure will be caused by the following factors:
(1) The non-standardized calculation may cover periods other than the 30-day
or one month period required by the standardize d calculation; (2) The
non-standardized calculation 

16

<PAGE>     17

may reflect amortization of premium based upon historical cost rather than
market value; (3) The non-standardized calculation may reflect the average
offering price per share for the period or the beginning  offering price per
share for the period, whereas the standardized calculation will always
reflect the maximum offering price per share on the last day of the period;
(4) The non-standardized calculation may reflect an offering price per share
other than  the maximum offering price, provided that any time the Fund's
return is quoted in reports, sales literature or advertisements using a
public offering price which is less than the Fund's maximum public offering
price, the return computed by using the Fund's maximum public offering price
also will be quoted in the same piece; (5) The non-standard return quotation
may include the effective return obtained by compounding the monthly
dividends. 
 
Average annual total return quotations show the average annual percentage
change in value of $1,000 for one, five and ten-year periods unless the Fund
has been in existence for a shorter period. Average annual total return
includes the effect of paying the maximum sales charge and assumes the
reinvestment of all dividends. The Fund also may furnish average annual
total return quotations for other periods, or based upon investments at
various sales charge levels or at net asset value. Total return quotations
show the total of all income and capital gain paid to shareholders, assuming
reinvestment of all distributions, plus (or minus) the change in the value of
the original investment, expressed as a percentage of the purchase price.  
 
Yields and returns described in this section may also be quoted on a
"taxable equivalent yield" basis by computing the taxable yield or return
which a hypothetical investor subject to a specified income tax rate must
realize to receive the same yield or return after taxes. When a taxable
equivalent yield is  quoted, the following additional information will be
furnished: (1) a standardized current yield; (2) the length of and the last
day of the base period used in computing the quotation; and (3) a description
of the method by which the quotation is computed. Yield and return
information may be useful in reviewing the performance of the Fund and for
providing a basis for comparison with other investment alternatives.
Comparative information about the yield or distribution rate of the shares of
the Fund and a bout average rates of return on certificates of deposit, bank
money market deposit accounts, money market mutual funds and other short-term
investments may also be included in advertisements and communications of the
Fund. Any such comparison will contain information about the differences
between the Fund and those investments. 

From time to time, in advertisements and other types of literature, the
performance of the Fund may be compared to other groups of mutual funds.
This comparative performance ma y be expressed as a ranking or a rating
prepared by Lipper Analytical Services, Inc., Donoghue Organization, Inc.,
Morningstar, Inc., Value Line or other widely recognized independent services
which monitor the performance of mutual funds.  Performance rankings and
ratings reported periodically in national financial publications such as
MONEY Magazine, FORBES, BARRON's, VALUE LINE, THE WALL STREET JOURNAL and
MORNINGSTAR, and other such publications may also be used. The Fund may
illustrate performance or the characteristics of its investment portfolio
through graphs, tabular data, or other displays which describe (i) the
average portfolio maturity of the Fund's portfolio securities relative to the
maturities of other investments, (ii) the relationship of yield and maturity
of the Fund to the yield and maturity of other investments (either as a
comparison or through use of standard benchmarks or indices such as the
Treasury yield curve), (iii) changes in the Fund's share price or net asset
value relative to changes in the value of other investments, and (iv) the
relationship over time of changes 
                                                                         17
<PAGE>     18

in the Fund's (or other investments) net asset values or prices and the
Fund's (or other investments') investment returns. The Fund also may
illustrate or refer to its respective investment portfolios, investment
techniques and strategies, and general market or economic trends in
advertising or communications to shareholders or prospective shareholders,
including reprints of interviews or articles written by or about, and
including comments by, Fund managers. These illustrations, references and
comments ordinarily will relate to topics addressed in the Fund's Prospectus
and Statement of Additional Information. 

ORGANIZATION OF THE FUND

The Fund is a nondiversified series of Thornburg Investment Trust, a
Massachusetts business trust (the "Trust") organized as a diversified,
open-end management investment company under a Declaration of Trust (the
"Declaration" ). The Fund is managed by the investment adviser, Thornburg
Management Company, Inc. under the supervision of the Trust's Trustees. The
Trust currently has 13 authorized Funds, one of which is described in this
Prospectus. The Trustees are authorized to divide the Trust's shares into
additional series and classes. 

The Fund may hold special shareholder meetings and mail proxy materials.
These meetings may be called to elect or remove Trustees, change fundamental
investment policies, or for other purposes. Shareholders not attending these
meetings are encouraged to vote by proxy. The Trust will mail proxy materials
in advance, including a voting card and information about the proposals to be
voted on. The number of votes you are entitled to is based upon the number of
shares you own.  Shares do not have cumulative voting rights or preemptive
rights. 
 
THORNBURG MANAGEMENT COMPANY, INC. & THORNBURG SECURITIES CORP.

The Fund is managed by Thornburg Management Company, Inc. (TMC).  TMC
performs investment management services for the Fund under the terms of an
Investment Advisory Agreement which specifies that TMC will select
investments for the Fund, monitor those investments and the markets
generally, and perform related services.  TMC also performs administrative
services specific to each class of shares of the Fund under an Administrative
Services Agreement which requires that TMC will supervise, administer and
perform certain administrative services necessary for the maintenance of
shareholders.  TMC's services to the Fund are supervised by the Trustees of
Thornburg Investment Trust.

For the Fund, TMC receives a management fee and an administrative services
fee, computed according to the following scales and paid monthly as a
percentage of the Fund's average daily net assets:

TMC was established in 1982. Today, the Thornburg Funds include Thornburg
Value Fund, Thornburg Limited Term U.S. Government Fund, Thornburg Limited
Term Income Fund, Thornburg Limited Term Municipal Fund National Portfolio,
Thornburg Limited Term Municipal Fund California Portfolio, Thornburg
Intermediate Municipal Fund, Thornburg New Mexico Intermediate Municipal Fund
and Thornburg Florida Intermediate Municipal Fund, in addition to the Fund
covered by this Prospectus. The Thornburg Funds total over $1.6 billion in
assets. Thornburg Management Company, Inc. is known as a provider of
conservative investment products. For more than a decade the Thornburg Funds
have been committed to preserving and increasing the real wealth of their
shareholders. The key to growing real wealth is increasing buying power after
taxes, inflation, and investment related expenses.

Brian J. McMahon and George Strickland, both of whom are Managing Directors
of TMC, have primary responsibility for the day-to-day management of the Fund
portfolio. They have held this responsibility since its commencement of
investment operations in 1997.  Mr. McMahon has managed municipal bond
portfolios for TMC since 1984 and Mr. Strickland has performed municipal bond
credit analysis and management since joining TMC in 1991.  Mr. McMahon and
Mr. Strickland are assisted by other employees of TMC in managing the Fund. 

TMC may, from time to time, agree to waive its fees or to reimburse the Fund
for expenses above a specified percentage of average daily net assets. TMC
retains the ability to be repaid by the Fund if expenses fall below the limit
prior to the end of the fiscal year. Fee waivers and expense reimbursements
will increase the Fund's yield, and repayment of waivers or reimbursements
will lower the Fund's yield.
 
In addition to TMC's fees, the Fund will pay all other costs and expenses of
its operations. The Fund will not bear any costs of sales or promotion
incurred in connection with the distribution of its shares, except as
provided for under the service plan applicable to the Fund, as described
above under "Service Plan." 

Thornburg Securities Corporation (TSC) distributes and markets the Thornburg
Funds. 

H. Garrett Thornburg, Jr. a Trustee and President of the Trust and a Director
and Chairman of the Company, is the controlling stockholder of both TMC and
TSC.

                    INVESTMENT OBJECTIVES AND POLICIES

     The primary investment objective of the Fund is to provide for its
shareholders as high a level of current income exempt from Federal, New York
State and New York City personal income taxes as is consistent, in the view
of the Fund's investment adviser, TMC, with the preservation of shareholders'
capital.  The secondary investment objective of the Fund is reducing
fluctuations in net asset value per share relative to long-term municipal
bond portfolios, by maintaining a portfolio with a dollar-weighted average
maturity of normally three to ten years.  There is a risk in all investments,
however, and there can be no assurance that the Fund's objectives will be
achieved.  The objective of preservation of capital may preclude the Fund
from obtaining the highest available yields.  The Fund was organized on March
12, 1997.

     The dollar-weighted average effective maturity of the Fund's  portfolio 
normally is three to ten years.  Price changes in the Fund's  shares
therefore can be expected to be more moderate than the per share fluctuations
of portfolios with longer-term bonds.

     The Fund will seek to achieve its objectives by investing in a portfolio
of obligations issued by New York State and the political subdivisions and
the agencies thereof.  The Fund may invest in obligations of United States
possessions and territories or their agencies and instrumentalities.  The
Fund may invest more than 5% of its portfolio assets in the securities of a
single issuer, provided that it may not purchase any security (other than
certain United States government securities) if, as a result, more than 5% of
the Trust's total assets would be invested in securities of a single issuer.

     The Fund's assets will normally consist of (1) Municipal Obligations or
participation interests therein that are rated at the time of purchase within
the four highest grades Aaa, Aa, A, Baa by Moody's Investors Service
("Moody's"), or AAA, AA, A, BBB by Standard & Poor's Corporation ("S&P"), or
Fitch Investors Service ("Fitch"), (2) Municipal Obligations or participation
interests therein that are not rated by a rating agency, but are issued by
obligors that either have other comparable debt obligations that are rated
within the four highest grades by Moody's S&P or Fitch, or, in the case of
obligors whose obligations are unrated, are deemed by TMC to be comparable
with issuers having such debt ratings, and (3) a small amount of cash or
equivalents.  In normal conditions, the Fund will hold cash pending

<PAGE>     2

investment in portfolio securities or anticipated redemption requirements. 
For an explanation of these ratings, please see "Ratings," page 6.  to the
extent that unrated Municipal Obligations may be less liquid, there may be
somewhat greater risk in purchasing unrated Municipal Obligations than in
purchasing comparable, rated Municipal Obligations.  If the Fund experienced
unexpected net redemptions, it could be forced to sell such unrated Municipal
Obligations at disadvantageous prices without regard to the Obligations'
investment merits, depressing the Fund's net asset value and possibly
reducing the Fund's overall investment performance.

     Except to the extent that the Fund is invested in temporary investments
for defensive purposes, the Fund will, under normal conditions, invest 100%
of its net assets in Municipal Obligations and normally will not invest less
than 80% of its net assets in Municipal Obligations.  This 80% policy is a
fundamental investment policy of the Fund and may be changed only with the
approval of a majority of the outstanding voting securities of the Fund. 
Under normal conditions, the Fund will attempt to invest 100%, and as a
matter of fundamental policy, will invest at least 65% of its net assets in
Municipal Obligations which originate in New York State.

     The ability of the Fund to achieve its investment objectives is
dependent upon the continuing ability of issuers of Municipal Obligations in
which the Fund invests to meet their obligations for the payment of interest
and principal when due.  In addition to using information provided by the
rating agencies, TMC will subject each issue under consideration for
investment to its own credit analysis in an effort to assess each issuer's
financial soundness.  This analysis is performed on a continuing basis for
all issues held by the Fund.  TMC subjects each issue under consideration for
investment to the same or similar credit analysis that TMC applies to rated
issues.

     Credit ratings are helpful in evaluating bonds, but are relevant
primarily to the safety of principal and interest payments under the bonds. 
These ratings do not reflect the risk that market values of bonds will
fluctuate with changes in interest rates.  Additionally, credit rating
agencies may fail to change credit ratings in a timely fashion to reflect
events subsequent to initial ratings.  The Fund's investment adviser, TMC,
reviews data respecting the issuers of the Fund's portfolio assets on an
ongoing basis, and may dispose of portfolio securities upon a change in
ratings or adverse events not reflected in ratings.

     The Fund has reserved the right to invest up to 20% of its net assets in
"temporary investments" in taxable securities (of comparable quality to the
above tax-exempt investments) that would produce interest not exempt from
Federal income tax or income taxes imposed by New York State and New York
City.  Such temporary investments, which may include repurchase agreements
with dealers, banks or recognized financial institutions that in the opinion
of TMC represent minimal credit risk, may be made due to market conditions,
pending investment of idle funds or to afford liquidity.  See "Temporary
Investments," at page 8.  Such investments are, like any investment, subject
to market risks and fluctuations in value.  In addition, the Fund's temporary
taxable investments may exceed 20% of its net assets when made for defensive
purposes during periods of abnormal market conditions.  The Fund does not
expect to find it necessary to make temporary investments in taxable
investments.

     The Fund will not purchase securities if, as a result, more than 25% of
the Fund's total assets would be invested in any one industry.  However, this
restriction will not apply to purchase of (i) securities of the United States
Government and its agencies, instrumentalities and authorities, or (ii) tax
exempt securities issued by other governments or political subdivisions,
because these issuers are not considered to be members of any industry.  This
restriction may not be changed unless approved by a majority of the
outstanding shares of the Fund.

     The Fund's investment objectives and policies, unless otherwise
specified, are not fundamental policies and may be changed by the Trustees
without shareholder approval. 

Municipal Obligations

     Municipal Obligations include debt and lease obligations issued by
states, cities and local authorities to obtain funds for various public

<PAGE>     3

purposes, including the construction of a wide range of public facilities
such as airports, bridges, highways, housing, hospitals, mass transportation,
schools, streets and water and sewer works.  Other public purposes for which
Municipal Obligations may be issued include the refunding of outstanding
obligations, the procurement of funds for general operating expenses and the
procurement of funds to lend to other public institutions and facilities.  In
addition, certain types of industrial development bonds are issued by or on
behalf of public authorities to obtain funds to provide privately-operated
housing facilities, sports facilities, convention or trade show facilities,
airport, mass transit, port or parking facilities, air or water pollution
control facilities and certain local facilities for water supply, gas,
electricity or sewage or solid waste disposal.  Municipal Obligations have
also been issued to finance single-family mortgage loans and to finance
student loans.  Such obligations are included within the term "Municipal
Obligations" if the interest paid thereon is exempt from federal income tax.

     The two principal classifications of Municipal Obligations are "general
obligation" and "revenue" bonds.  General obligation bonds are secured by the
issuer's pledge of its faith, credit and taxing power for the payment of
principal and interest.  Revenue bonds are payable only from the revenues
derived from a particular facility or class of facilities or, in some cases,
from the proceeds of a specific revenue source.  Industrial development bonds
are in most cases revenue bonds and are generally not secured by the pledge
of the credit or taxing power of the issuer of such bonds.  There are, of
course, variations in the security of Municipal Obligations, both within a
particular classification and between classifications, depending on numerous
factors.

     The Fund may invest in a variety of types of Municipal Obligations,
including but not limited to bonds, notes (such as tax anticipation and
revenue anticipation notes), commercial paper and variable rate demand
instruments.  Variable rate demand instruments are Municipal Obligations or
participations therein, either publicly underwritten and traded or privately
purchased, that provide for a periodic adjustment of the interest rate paid
on the instrument and permit the holder to demand payment of the unpaid
principal amount and accrued interest upon not more than seven days' notice
either from the issuer or by drawing on a bank letter of credit, a guarantee
or insurance issued with respect to such instrument.  Such Letters of Credit,
guarantees or insurance will be considered in determining whether a Municipal
Obligation meets the Fund's investment criteria.  See the Prospectus under
the caption "Investment Objectives and Policies - Municipal Obligations." 
The issuer of a variable rate demand instrument may have the corresponding
right to prepay the principal amount prior to maturity.

     The Fund also may purchase fixed rate municipal demand instruments
either in the public market or privately.  Such instruments may provide for
periodic adjustment of the interest rate paid to the holder.  The "demand"
feature permits the holder to demand payment of principal and interest prior
to their final stated maturity, either from the issuer or by drawing on a
bank letter of credit, a guarantee or insurance issued with respect to the
instrument.  In some cases these demand instruments may be in the form of
units, each of which consists of (i) a Municipal Obligation and (ii) a
separate put option entitling the holder to sell to the issuer of such option
the Municipal Obligation in such unit, or an equal aggregate principal amount
of another Municipal Obligation of the same issuer, issue and maturity as
such Municipal Obligation, at a fixed price on specified dates during the
term of the put option.  In those cases, each unit taken as a whole will be
considered a Municipal Obligation, based upon an accompanying opinion of
counsel.  The Fund will invest in a fixed rate municipal demand instrument

<PAGE>     4

only if the instrument or the associated letter of credit, guarantee or
insurance is rated within the three highest grades of a nationally recognized
rating agency, or, if unrated, is deemed by TMC to be of comparable quality
with issues having such debt ratings.  The credit quality of such investments
will be determined on a continuing basis by TMC under the supervision of the
Trustees.

     The Fund also may purchase and sell Municipal Obligations on a
when-issued or delayed delivery basis.  When-issued and delayed delivery
transactions arise when securities are purchased or sold with payment and
delivery beyond the regular settlement date.  (When-issued transactions
normally settle within 30-45 days.)  On such transactions the payment
obligation and the interest rate are fixed at the time the buyer enters into
the commitment.  The commitment to purchase securities on a when-issued or
delayed delivery basis may involve an element of risk because the value of
the securities is subject to market fluctuation, no interest accrues to the
purchaser prior to settlement of the transaction, and at the time of delivery
the market value may be less than cost.  At the time the Fund makes the
commitment to purchase a Municipal Obligation on a when-issued or delayed
delivery basis, it will record the transaction and reflect the value of the
security in determining its net asset value.  The Fund also will maintain
liquid assets at least equal in value to commitments for when-issued or
delayed delivery securities, such assets to be segregated by State Street
Bank & Trust Co., the Fund's custodian, specifically for the settlement of
such commitments.  The value of the segregated assets will be marked to the
market daily so that the Fund will at all times maintain assets in the
segregated account equal in value to the amount of these commitments.  The
Fund will only make commitments to purchase Municipal Obligations on a
when-issued or delayed delivery basis with the intention of actually
acquiring the securities, but the Fund reserves the right to sell these
securities before the settlement date if it is deemed advisable.  If a
when-issued security is sold before delivery any gain or loss would not be
tax-exempt.

     TMC will evaluate the liquidity of each Municipal Lease upon its
acquisition and periodically while it is held based upon factors established
by the Trustees, including (i) the frequency of trades and quotes for the
obligation, (ii) the number of dealers who will buy or sell the obligation
and the potential buyers for the obligation, (iii) the willingness of dealers
to make a market for the obligation, and (iv) the nature and timing of
marketplace trades.  An unrated Municipal Lease with non-appropriation risk
that is backed by an irrevocable bank letter of credit or an insurance
policy, issued by a bank or insurer deemed by TMC to be of high quality and
minimal credit risk, will not be deemed to be "illiquid" solely because the
underlying Municipal Lease is unrated, if TMC determines that the Municipal
Lease is readily marketable because it is backed by such letter of credit or
insurance policy.

     The Fund will seek to reduce further the special risks associated with
investment in Municipal Leases by investing in Municipal Leases only where,
in TMC's opinion, certain factors established by the Trustees have been
satisfied, including (i) the nature of the leased equipment or property is
such that its ownership or use is deemed essential to a governmental function
of the governmental issuer, (ii) the Municipal Lease has a shorter term to
maturity than the estimated useful life of the leased property and the lease
payments will commence amortization of principal at an early date,
(iii) appropriate covenants will be obtained from the governmental issuer
prohibiting the substitution or purchase of similar equipment for a specified
period (usually 60 days or more) in the event payments are not appropriated,

<PAGE>     5

(iv) the underlying equipment has elements of portability or use that enhance
its marketability in the event foreclosure on the underlying equipment was
ever required, and (v) the governmental issuer's general credit is adequate. 
The enforceability of the "non-substitution" provisions referred to in (iii)
above has not been tested by the courts.  Investments not meeting certain of
these criteria (such as the absence of a non-substitution clause) may be made
if the Municipal Lease is subject to an agreement with a responsible party
(such as the equipment vendor) providing warranties to the Fund that satisfy
such criteria.

     Municipal Leases usually grant the lessee the option to purchase the
leased property prior to maturity of the obligation by payment of the unpaid
principal amount of the obligation and, in some cases, a prepayment fee. 
Such prepayment may be required in the case of loss or destruction of the
property.  The prepayment of the obligation may reduce the expected yield on
the invested funds if interest rates have declined below the level prevailing
when the obligation was purchased.

     The Fund will not invest in illiquid securities if, as a result of the
investment, more than 10% of its net assets will be invested in illiquid
securities.  For purposes of this limitation, "illiquid securities" shall be
deemed to include (1) Municipal Leases subject to non-appropriation risk
which are not rated at the time of purchase within the four highest grades by
Moody's or S&P and not subject to remarketing agreements (or not currently
subject to remarketing, pursuant to the conditions of any such agreement then
in effect, with a responsible remarketing party, deemed by TMC to be capable
of performing its obligations), (2) repurchase agreements maturing in more
than seven days, (3) securities which the Fund is restricted from selling to
the public without registration under the Securities Act of 1933, and
(4) other securities or participations not considered readily marketable by
the Fund, provided that for purposes of the foregoing an unrated Municipal
Lease which is backed by an irrevocable bank letter of credit or an insurance
policy, issued by a bank or insurer deemed by TMC to be of high quality and
minimal credit risk, will not be deemed to be illiquid.

     From time to time, proposals have been introduced before Congress for
the purpose of restricting or eliminating the federal income tax exemption
for interest on municipal securities.  Similar proposals may be introduced in
the future.  These proposals, if enacted, may have the effect of reducing the
availability of investments for the Fund.  Moreover, the value of the Fund's
portfolio may be affected.  The Fund could be compelled to reevaluate its
investment objectives and policies and submit possible changes in the
structure of the Fund for the approval of shareholders.

     The yields on Municipal Obligations are dependent on a variety of
factors, including the condition of the general market and the Municipal
Obligation market, the size of a particular offering, the maturity of the
obligation and the rating of the issue.  The ratings of Moody's, S&P and
Fitch represent their opinions as to the quality of the Municipal Obligations
which they undertake to rate.  See "Ratings."  It should be emphasized,
however, that ratings are general and are not absolute standards of quality. 
Consequently, Municipal Obligations with the same maturity, coupon and rating
may have different yields, while Municipal Obligations of the same maturity
and coupon with different ratings may have the same yield.  The market value
of outstanding Municipal Obligations will vary with changes in prevailing
interest rate levels and as a result of changing evaluations of the ability
of their issuers to meet interest and principal payments.  Such variations in

<PAGE>     6

market value of Municipal Obligations held in the Fund's portfolio arising
from these or other factors will cause changes in the net asset value of the
Fund's shares.

Ratings

     Tax-Exempt Bonds.  The four highest ratings of Moody's for tax-exempt
bonds are Aaa, Aa, A and Baa.  Tax-exempt bonds rated Aaa are judged to be of
the "best quality."  The rating of Aa is assigned to tax-exempt bonds which
are of "high quality by all standards," but as to which margins of protection
or other elements make long-term risks appear somewhat larger than Aaa rated
tax-exempt bonds.  The Aaa and Aa rated tax-exempt bonds comprise what are
generally known as "high grade bonds."  Tax-exempt bonds which are rated A by
Moody's possess many favorable investment attributes and are considered
"upper medium grade obligations."  Factors giving security to principal and
interest of A rated tax-exempt bonds are considered adequate, but elements
may be present which suggest a susceptibility to impairment sometime in the
future.  Tax-exempt bonds rated Baa are considered  "medium grade"
obligations.  They are neither highly protected nor poorly secured.  Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable
over any great length of time.  Such tax-exempt bonds lack outstanding
investment characteristics and in fact have speculative characteristics as
well.  The foregoing ratings are sometimes presented in parentheses preceded
with "Con." indicating the bonds are rated conditionally.  Bonds for which
the security depends upon the completion of some act or the fulfillment of
some condition are rated conditionally.  These are bonds secured by (a)
earnings of projects under construction, (b) earnings of projects unseasoned
in operating experience, (c) rentals which begin when facilities are
completed, or (d) payments to which some other limiting condition attaches. 
The parenthetical rating denotes the probable credit status upon completion
of construction or elimination of the basis of the condition.

     The four highest ratings of S&P and Fitch for tax-exempt bonds are AAA,
AA, A, and BBB.  Tax-exempt bonds rated AAA bear the highest rating assigned
by S&P and Fitch to a debt obligation and indicates an extremely strong
capacity to pay principal and interest.  Tax-exempt bonds rated AA also
qualify as high-quality debt obligations.  Capacity to pay principal and
interest is very strong, and in the majority of instances they differ from
AAA issues only in small degree.  Bonds rated A have a strong capacity to pay
principal and interest, although they are somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions.  The BBB
rating, which is the lowest "investment grade" security rating by S&P or
Fitch,  indicates an adequate capacity to pay principal and interest. 
Whereas BBB rated Municipal Obligations they normally exhibit adequate
protection parameters, adverse economic conditions or changing circumstances
are more likely to lead to a weakened capacity to pay principal and interest
for bonds in this category than for bonds in the A category.  The foregoing
ratings are sometimes followed by a "p" indicating that the rating is
provisional.  A provisional rating assumes the successful completion of the
project being financed by the bonds being rated and indicates that payment of
debt service requirements is largely or entirely dependent upon the
successful and timely completion of the project.  This rating, however, while
addressing credit quality subsequent to completion of the project, makes no
comment on the likelihood of, or the risk of default upon failure of, such
completion.

<PAGE>     7

     Municipal Notes.  The ratings of Moody's for municipal notes are MIG 1,
MIG 2, MIG 3 and MIG 4.  Notes bearing the designation MIG 1 are judged to be
of the best quality, enjoying strong protection from established cash flows
of funds for their servicing or from established and broad-based access to
the market for refinancing, or both.  Notes bearing the designation MIG 2 are
judged to be of high quality, with margins of protection ample although not
so large as in the preceding group.  Notes bearing the designation of MIG 3
are judged to be of favorable quality, with all security elements accounted
for but lacking the undeniable strength of the preceding grades.  Market
access for refinancing, in particular, is likely to be less well established. 
 Notes bearing the designation MIG 4 are judged to be of adequate quality,
carrying specific risk but having protection commonly regarded as required of
an investment security and not distinctly or predominantly speculative.

     The S&P ratings for municipal notes are SP-1+, SP-1, SP-2 and SP-3. 
Notes bearing an SP-1+ rating are judged to possess overwhelming safety
characteristics, with either a strong or very strong capacity to pay
principal and interest.  Notes rated SP-1 are judged to have either a strong
or very strong capacity to pay principal and interest but lack the
overwhelming safety characteristics of notes rated SP-1+.  Notes bearing an
SP-2 rating are judged to have a satisfactory capacity to pay principal and
interest, and notes rated SP-3 are judged to have a speculative capacity to
pay principal and interest.

     Tax-Exempt Demand Bonds.  The rating agencies may assign dual ratings to
all long term debt issues that have as part of their provisions a demand or
multiple redemption feature.  The first rating addresses the likelihood of
repayment of principal and interest as due and the second rating addresses
only the demand feature.  The long term debt rating symbols are used for
bonds to denote the long term maturity and the commercial paper rating
symbols are used to denote the put option (for example, "AAA/A-1+").  For
newer "demand notes" maturing in 3 years or less, the respective note rating
symbols, combined with the commercial paper symbols, are used (for example.
"SP-1+/A-1+").

     Commercial Paper.  The ratings of Moody's for issuers of commercial
paper are Prime-1, Prime-2 and Prime-3.  Issuers rated Prime-1 are judged to
have superior ability for repayment which is normally evidenced by (i)
leading market positions in well established industries, (ii) high rates of
return on funds employed, (iii) conservative capitalization structures with
moderate reliance on debt and ample asset protection, (if) broad margins in
earnings coverage of fixed financial charges and high internal cash
generation, and (v) well established access to a range of financial markets
and assured sources of alternate liquidity.  Issuers rated Prime-2 are judged
to have a strong capacity for repayment which is normally evidenced by many
of the characteristics cited under the discussion of issuers rated Prime-1
but to a lesser degree.  Earnings trends, while sound, will be more subject
to variation.  Capitalization characteristics, while still appropriate, may
be more affected by external conditions.  Adequate liquidity is maintained. 
Issuers rated Prime-3 are judged to have an acceptable capacity for
repayment.  The effect of industry characteristics and market composition may
be more pronounced.  Variability of earnings and profitability may result in
changes in the level of debt-protection measurements and the requirement for
relatively high financial leverage.  Adequate alternate liquidity is
maintained.

<PAGE>     8

     The ratings of S&P for commercial paper are A (which is further
delineated by Categories A-1+, A-1, A-2 and A-3), B, C and D.  Commercial
paper rated A is judged to have the greatest capacity for timely payment. 
Commercial paper rated A-1+ is judged to possess overwhelming safety
characteristics.  Commercial paper rated A-1 is judged to possess an
overwhelming or very strong degree of safety.  Commercial paper rated A-2 is
judged to have a strong capacity for payment although the relative degree of
safety is not as high as for paper rated A-1.  Commercial paper rated A-3 is
judged to have a satisfactory capacity for timely payment but is deemed to be
somewhat more vulnerable to the adverse changes in circumstances than paper
carrying the higher ratings.  Commercial paper rated B is judged to have an
adequate capacity for timely payment but such capacity may be impaired by
changing conditions or short-term adversities.

Temporary Investments

     The Fund has reserved the right to invest up to 20% of its net assets in
"temporary investments" in taxable securities that would produce interest not
exempt from federal income tax.  See "Distributions and Taxes."  Such
temporary investments may be made due to market conditions, pending
investment of idle funds or to afford liquidity.  These investments are
limited to the following short-term, fixed-income securities (maturing in one
year or less from the time of purchase):  (i) obligations of the United
States government or its agencies, instrumentalities or authorities; (ii)
prime commercial paper within the two highest ratings of Moody's or S&P;
(iii) certificates of deposit of domestic banks with assets of $1 billion or
more; and (iv) repurchase agreements with respect to the foregoing types of
securities.  Repurchase agreements will be entered into only with dealers,
domestic banks or recognized financial institutions that in the opinion of
TMC represent minimal credit risk.  Investments in repurchase agreements are
limited to 5% of the Fund's net assets.  See "Repurchase Agreements."  In
addition, temporary taxable investments may exceed 20% of the Fund's net
assets when made for defensive purposes during periods of abnormal market
conditions.  The Fund does not expect to find it necessary to make such
temporary investments.

Repurchase Agreements

     The Fund may enter into repurchase agreements with respect to taxable
securities constituting "temporary investments" in its portfolio.  A
repurchase agreement is a contractual agreement whereby the seller of
securities agrees to repurchase the same security at a specified price on a
future date agreed upon by the parties.  The agreed upon repurchase price
determines the yield during the Fund's holding period.  Repurchase agreements
may be viewed as loans collateralized by the underlying security that is the
subject of the repurchase agreement.  The Fund will not enter into a
repurchase agreement if, as a result, more than 5% of the value of its net
assets would then be invested in repurchase agreements.  The Fund will enter
into repurchase agreements only with dealers, banks or recognized financial
institutions that in the opinion of TMC represent minimal credit risk.  The
risk to the Fund is limited to the ability of the seller to pay the agreed
upon repurchase price on the delivery date; however, although the value of
the underlying collateral at the time the transaction is entered into always
equals or exceeds the agreed upon repurchase price, if the value of the
collateral declines there is a risk of loss of both principal and interest if
the seller defaults.  In the event of a default, the collateral may be sold. 
The Fund might incur a loss if the value of the collateral has declined, and

<PAGE>     9

the Fund might incur disposition costs or experience delays in connection
with liquidating the collateral.  In addition, if bankruptcy proceedings are
commenced with respect to the seller of the security, realization upon the
collateral by the Fund may be delayed or limited.  The Fund's investment
adviser will monitor the value of the collateral at the time the transaction
is entered into and at all subsequent times during the term of the repurchase
agreement in an effort to determine that the value always equals or exceeds
the agreed upon repurchase price.  In the event the value of the collateral
declines below the repurchase price, the investment adviser will demand
additional collateral from the seller to increase the value of the collateral
to at least that of the repurchase price.

U.S. Government Obligations

     The Fund's temporary investments in taxable securities may include
obligations of the U.S. government.  These include bills, certificates of
indebtedness, notes and bonds issued or guaranteed as to principal or
interest by the United States or by agencies or authorities controlled or
supervised by and acting as instrumentalities of the U.S. government and
established under the authority granted by Congress, including, but not
limited to, the Government National Mortgage Association, the Tennessee
Valley Authority, the Bank for Cooperatives, the Farmers Home Administration,
Federal Home Loan Banks, Federal Intermediate Credit Banks, Federal Land
Banks, Farm Credit Banks and the Federal National Mortgage Association.  Some
obligations of U.S. government agencies, authorities and other
instrumentalities are supported by the full faith and credit of the U.S.
Treasury; others by the right of the issuer to borrow from the Treasury;
others only by the credit of the issuing agency, authority or other
instrumentality.  In the case of securities not backed by the full faith and
credit of the United States, the investor must look principally to the agency
issuing or guaranteeing the obligation for ultimate repayment, and may not be
able to assert a claim against the United States itself in the event the
agency or instrumentality does not meet its commitments.

                    NEW YORK ECONOMY AND PUBLIC FINANCE

     New York has enjoyed increased tax revenues recently from a growth in
personal income, continued strong performance in financial services, strong
consumer spending and tourism.  Current state spending estimates appear
reasonable in view of these revenue increases.  Medicaid cost containments,
slowing health care cost increases, abatement of public assistance costs and
other cost reduction measures also have permitted the state and local
governments generally to meet their obligations. 

     The current financial stability could be upset by a number of factors,
however.  Costs which are currently contained could increase if the state's
economy falters.  Public assistance costs and health care expense could
increase if unemployment increases.  Economic difficulties also could reduce
economic activity and consumer spending, reducing tax revenues in a period
when governmental costs likely would increase.

     The state also has enacted tax decreases, which will reduce revenue in
fiscal 1997 by an estimated $2.3 billion with an additional revenue loss of
$2.2 billion projected for fiscal 1998.  Additional legislation in fiscal
1997 will make additional estimated reductions in fiscal 1997 and 1998
revenue of $83 million and $178 million, respectively.  In the same regard,

<PAGE>     10

the state likely will have a natural growth in spending in coming years, and
will have to find additional revenues to cover expenditures financed with
approximately $1.3 billion in nonrecurring revenues in fiscal 1996.

     The ability of the state to respond to these challenges may be impaired
significantly, particularly if the economy weakens, because the state and
some local governments have failed to take advantage of the recent stronger
economy and increased public revenue to improve public finances.  Although
the state had an approximate $445 million cash balance at the end of fiscal
1996, the state's accumulated deficit was not reduced significantly in fiscal
1996, and amounted to approximately $2.93 billion.  In fiscal 1997 the state
continued to enjoy revenue increases, but these enhanced revenues have been
used for current spending instead of debt retirement and creation of
reserves.  Moreover, the state's undisciplined budget process continues to
rely on one time fixes and invasion of off-budget funds to achieve short-term
budget balance, at the expense of fiscally responsible long-term solutions to
the state's chronic budget deficit.

     Potential difficulties in this respect could be further aggravated by
the state's endemic inability to complete timely its annual budget process. 
The state did not enact its fiscal 1997 budget until July 13, 1996, 104 days
after the beginning of the fiscal year on April 1, 1996.  The 104 day delay
is the longest delay the state has endured in adopting a budget and the
longest delay for any state.  Budget negotiations were linked to the adoption
of other non-budget legislation, including reform of worker's compensation
laws and enactment of a new hospital rate setting scheme to replace the
existing program (NYPHRM -- the New York Prospective Hospital Reimbursement
Methodology).  Negotiations between the legislature and the governor on these
issues were deadlocked and delayed adoption of the budget.  In order to
provide for the continued functioning of state government services during the
budget delay, the governor and legislature periodically enacted special
emergency legislation with specific limited appropriations to fund state
worker payrolls, Medicaid and welfare payments, and other special needs as
they arose. 

     The state's structural budget deficit and chronic inability to adopt
timely budgets also disrupt financial planning by local governments, state
agencies, contract agencies and private vendors.  Many of these entities are
unable to plan effectively, and may incur additional interest costs for
short-term cash flow borrowings.

                          INVESTMENT LIMITATIONS

     The Fund has adopted the following fundamental investment policies which
may not be changed unless approved by a majority of the outstanding shares of
the Fund.  Under the Investment Company Act of 1940 (the "Act"), a "vote of
the majority of the outstanding voting securities" of the Fund means the
affirmative vote of the lesser of (1) more than 50% of the outstanding shares
of the Fund or (2) 67% or more of the shares of the Fund present at a
shareholders' meeting if more than 50% of the outstanding shares of such
series are represented at the meeting in person or by proxy.

<PAGE>     11

     The Fund may not:

     (1)  Invest in securities other than Municipal Obligations (including
participations therein) and temporary investments within the percentage
limitations specified in the Prospectus under the caption "Investment
Objective and Policies";

     (2)  Purchase any security (other than securities issued or guaranteed
as to principal or interest by the United States or its instrumentalities)
if, as a result, more than 5% of the Trust's total assets would be invested
in securities of a single issuer;

     (3)  Borrow money, except for temporary or emergency purposes and not
for investment purposes, and then only in an amount not exceeding 5% of the
value of the Fund's total assets at the time of borrowing;

     (4)  Pledge, mortgage or hypothecate its assets, except to secure
borrowings permitted by subparagraph (3) above;

     (5)  Issue senior securities as defined in the Investment Company Act of
1940, except insofar as the Fund may be deemed to have issued a senior
security by reason of (a) entering into any repurchase agreement; (b)
purchasing any securities on a when-issued or delayed delivery basis; or (c)
borrowing money in accordance with the restrictions described above; 

     (6)  Underwrite any issue of securities, except to the extent that, in
connection with the disposition of portfolio securities, it may be deemed to
be an underwriter under the federal securities laws;

     (7)  Purchase or sell real estate and real estate mortgage loans, but
this shall not prevent the Fund from investing in Municipal Obligations
secured by real estate or interests therein;

     (8)  Purchase or sell commodities or commodity futures contracts or oil,
gas or other mineral exploration or development programs;

     (9)  Make loans, other than by entering into repurchase agreements and
through the purchase of Municipal Obligations or temporary investments in
accordance with its investment objectives, policies and limitations;

     (10) Make short sales of securities or purchase any securities on
margin, except for such short-term credits as are necessary for the clearance
of transactions;

     (11) Write or purchase puts, calls, straddles, spreads or other
combinations thereof, except to the extent that securities subject to a
demand obligation or to a remarketing agreement may be purchased as set forth
in the Prospectus under the captions "Investment Objectives and Policies --
Municipal Obligations";

     (12) Invest more than 5% of its total assets in securities of unseasoned
issuers which, together with their predecessors, have been in operation for
less than three years excluding (i) obligations of, or guaranteed by, the
United States government, its agencies, instrumentalities and authorities and

<PAGE>     12

(ii) obligations secured by the pledge of the faith, credit and taxing power
of any entity authorized to issue Municipal Obligations;

     (13) Invest more than 5% of its total assets in securities which the
Fund is restricted from selling to the public without registration under the
Securities Act of 1933;

     (14) Purchase securities of any issuer if such purchase at the time
thereof would cause more than 10% of the voting securities of any such issuer
to be held by the Fund;

     (15) Purchase securities of other investment companies, except in
connection with a merger, consolidation, reorganization or acquisition of
assets;

     (16) Purchase securities (other than securities of the United States
government, its agencies, instrumentalities and authorities) if, as a result,
more than 25% of the Fund's total assets would be invested in any one
industry;

     (17) Purchase or retain the securities of any issuer other than the
securities issued by the Fund itself if, to the Fund's knowledge, those
officers and trustees of the Fund, or those officers and directors of TMC,
who individually own beneficially more than 1/2 of 1% of the outstanding
securities of such issuer, together own beneficially more than 5% of such
outstanding securities; or 

     (18) Purchase the securities of any issuer if as a result more than 10%
of the value of the Fund's net assets would be invested in restricted
securities, unmarketable securities and other illiquid securities (including
repurchase agreements of more than seven days maturity and other securities
which are not readily marketable).

     For the purpose of applying the limitations set forth in paragraphs (2)
and 12 above, an issuer shall be deemed a separate issuer when its assets and
revenues are separate from other governmental entities and its securities are
backed only by its assets and revenues.  Similarly, in the case of a
nongovernmental user, such as an industrial corporation or a privately owned
or operated hospital, if the security is backed only by the assets and
revenues of the nongovernmental user, then such nongovernmental user would be
deemed to be the sole issuer.  Where a security is also guaranteed by the
enforceable obligation of another entity it shall also be included in the
computation of securities owned that are issued by such other entity.  In
addition, for purposes of paragraph (2) above, a remarketing party entering
into a remarketing agreement with the Fund as described in the Prospectus
under the caption "Investment Objective and Policies -- Municipal
Obligations" shall not be deemed an "issuer" of a security or a "guarantor"
pursuant to such agreement.

     With respect to temporary investments, in addition to the foregoing
limitations the Fund will not enter into a repurchase agreement if, as a
result thereof, more than 5% of its net assets would be subject to repurchase
agreements.

     Although the Fund has the right to pledge, mortgage or hypothecate its
assets in order to comply with certain state statutes on investment
restrictions, the Fund will not, as a matter of operating policy (which
policy may be changed by the Trustees without shareholder approval), pledge,

<PAGE>     13

mortgage or hypothecate its portfolio securities to the extent that at any
time the percentage of pledged securities will exceed 10% of its total
assets.

     In the event the Fund acquires disposable assets as a result of the
exercise of a security interest relating to Municipal Obligations, it will
dispose of such assets as promptly as possible.

     Rule 18f-2 under the Act provides that any matter required to be
submitted by the provisions of the Act or applicable state law, or otherwise,
to the holder of the outstanding voting securities of series investment
companies such as the Trust shall not be deemed to have been effectively
acted upon unless approved by the holders of a majority of the outstanding
shares of each Fund or "series" affected by the matter.  Rule 18f-2 further
provides that a series shall be deemed to be affected by a such a matter
unless it is clear that the interests of each series in the matter are
substantially identical or that the matter does not affect any interest of
such series deemed not to be affected.  However, the Rule exempts the
selection of independent public accountants, the approval of principal
distribution contracts and the election of directors and trustees from the
separate voting requirements of the Rule.



                      YIELD AND RETURN COMPUTATION: 
                   Performance and Portfolio Information

Computation of Yield and Return - In General

     The return or yield of the Fund may, from time to time, be quoted in
reports, sales literature and advertisements published by the Fund, the
Fund's principal underwriter, or investment dealers offering shares issued by
the Trust.  Any such quotation must include a standardized calculation which
computes yield for a 30-day or one month period by dividing the Fund's net
investment income per share during the period by the maximum offering price
on the last day of the period.  The standardized calculation may include the
effect of semiannual compounding and will reflect amortization of premiums
for those bonds which have a market value in excess of par.  New schedules
based on market value will be computed each month for amortizing premiums. 
Provided that any such quotation also is accompanied by the standardized
calculation referred to above, the Fund also may quote non-standardized
performance data of its classes for a specified period by dividing the net
investment income per share for that period by either the Fund's average
public offering price per share for that same period or the offering price
per share on the first or last day of the period, and multiplying the result
by 365 divided by the number of days in the specified period.  For purposes
of this non-standardized calculation net investment income will include
accrued interest income plus or minus any amortized purchase discount or
premium less accrued expenses.  The primary differences between the yield
calculations obtained using the standardized performance measure and any
non-standardized performance measure will be caused by the following factors: 
(1) The non-standardized calculation may cover periods other than the 30-day
or one month period required by the standardized calculation; (2) The
non-standardized calculation may reflect amortization of premium based upon
historical cost rather than market value.  Amortization of premium based upon
historical cost is required by the Internal Revenue Service for tax reporting
purposes; (3) The non-standardized calculation may reflect the average
offering price per share for the period of the beginning offering price per
share for the period, whereas the standardized calculation will always

<PAGE>     14

reflect the maximum offering price per share on the last day of the period;
(4) the non-standardized calculation may reflect an offering price per share
other than the maximum offering price; provided that any time the Fund's
performance is quoted in reports, sales literature or advertisements using a
public offering price, the performance computed by using the Fund's maximum
public offering price also will be quoted in the same piece; and (5) The
non-standardized performance quotation may include the effective return
obtained by compounding the monthly dividends.

     Any performance computation also must include average annual total
return quotations for the 1, 5 and 10 year periods ended on the date of the
most recent balance sheet included in the registration statement, computed by
finding the average annual compounded rates of return over such periods which
would equate the initial amount invested at the maximum public offering price
to the ending redeemable value.  To the extent that a fund or a class has
been in operation less than 1, 5 and 10 years, the time period during which
the fund or the class has been in operation will be substituted for any 1, 5
or 10 year period for which a total return quotation is not obtainable.

     Yield or total return quotations described in this section also may be
quoted on a "taxable equivalent yield" basis, provided that the following
information is furnished:  (1) a standardized taxable equivalent yield based
on a 30-day or one month period ended on the date of the most recent balance
sheet included in the registration statement; (2) the length of and the last
day of the base period used in computing the quotation; and (3) a description
of the method by which the quotation is computed.

Additional Portfolio and Performance Information

     The Fund also may illustrate performance or the characteristics of its
investment portfolio or classes of the Fund through graphs, tabular data or
other displays which describe (i) the average portfolio maturity of the
Fund's portfolio securities relative to the maturities of other investments,
(ii) the relationship of yield and maturity of the Fund to the yield and
maturity of other investments (either as a comparison through use of standard
bench marks or indices such as the Treasury yield curve), (iii) changes in
the Fund's share price or net asset value relative to changes in the value of
other investments, and (iv) the relationship over time of changes in the
Fund's (or other investments') net asset value or price and the Fund's (or
other investments') investment return.

                          DISTRIBUTIONS AND TAXES

Distributions

     All of the net income of the Fund is declared daily as a dividend on
shares for which it has received payment.  Net income of the Fund consists of
all interest income accrued on portfolio assets less all expenses of the
Fund.  Expenses of the Fund are accrued each day.  Dividends are paid monthly
and are reinvested in additional shares of the Fund at the net asset value
per share at the close of business on the dividend payment date or, at the
shareholder's option, paid in cash.  Net realized capital gains, if any, will
be distributed annually and reinvested in additional shares of the Fund at
the net asset value per share at the close of business on the distribution

<PAGE>     15

date, or, at the shareholder's option, paid in cash.  See "Accounts of
Shareholders."

Federal Income Tax Matters

     The Fund intends to qualify under Subchapter M of the Internal Revenue
Code (the "Code") for tax treatment as a regulated investment company.  This
tax treatment relieves the Fund from paying federal income tax on income
which is currently distributed to its shareholders.  The Fund also intends to
satisfy conditions (including requirements as to the proportion of its assets
invested in Municipal Obligations) which will enable it to designate
distributions from the interest income generated by its investments in
Municipal Obligations, which are exempt from federal income tax when received
by the Fund, as Exempt Interest Dividends.  Individual shareholders receiving
Exempt Interest Dividends will not be subject to the federal personal income
tax on the amount of those dividends, except to the extent the alternative
minimum tax may be applicable.

     Under the Code, interest on indebtedness incurred or continued to
purchase or carry shares is not deductible.  Under rules issued by the
Department of the Treasury for determining when borrowed funds are considered
used for the purpose of purchasing or carrying particular assets, the
purchase of shares may be considered to have been made with borrowed funds
even though the borrowed funds are not directly traceable to the purchase of
shares.  Investors with questions regarding this issue should consult with
their own tax advisers.

     Shares of the Fund may not be an appropriate investment for persons who
are "substantial users" of facilities financed by industrial development
bonds (including any Municipal Lease that may be deemed to constitute an
industrial development bond) or persons related to such "substantial users." 
Such persons should consult their own tax advisers before investing in Fund
shares.

     Distributions by the Fund of net interest income received from certain
temporary investments (such as certificates of deposit, commercial paper and
obligations of the United States government, its agencies, instrumentalities
and authorities), amounts attributable to market discount on bonds and net
short-term capital gains realized by the Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional
shares.  Distributions to shareholders will not qualify for the dividends
received deduction for corporations.

     Any net long-term capital gains realized by the Fund, whether
distributed in cash or reinvested in additional shares, must be treated as
long-term capital gains by shareholders regardless of the length of time
investors have held their shares.  If the Fund should have net undistributed
capital gains in any year, the Fund would pay the tax on such gains and each
shareholder would be deemed, for federal tax purposes, to have paid his or
her pro rata share of such tax.

     If in any year the Fund should fail to qualify under Subchapter M for
tax treatment as a regulated investment company, (i) the Fund would incur a
regular corporate federal income tax upon its net interest income, other than
interest income from Municipal Obligations, for that year, and (ii)
distributions to its shareholders out of net interest income from Municipal

<PAGE>     16

Obligations or other investments, or out of net capital gains, would be
taxable to shareholders as ordinary dividend income for federal income tax
purposes to the extent of the Fund's current or accumulated earnings or
profits.  The Fund would fail to qualify under Subchapter M if, among other
requirements, in any year (i) 30% or more of its gross income were derived
from the sale or other disposition of securities held for less than three
months, (ii) less than 90% of the Fund's gross income were derived from
specified income sources such as dividends, interest and gains from the
disposition of stock or securities or (iii) the Fund fails to satisfy the
diversification of investments requirement of the Code and fails to timely
cure the failure.  Furthermore, the Fund would be unable to pay Exempt
Interest Dividends if, at the close of any quarter of its taxable year, more
than 50% of the value of that Fund's total assets consisted of assets other
than Municipal Obligations.  Additionally, if in any year the Fund qualified
as a regulated investment company but failed to distribute all of its net
income, the Fund would be taxable on the undistributed portion of its net
income.  Although the Fund intends to distribute all of its net income
currently, the Fund could have undistributed net income if, for example,
expenses of the Fund were reduced or disallowed on audit.

     If the Fund has both tax-exempt and taxable interest, it will use the
"actual earned method" for determining the designated percentage that is
taxable income and designate the use of that method within 45 days after the
end of the Fund's taxable year.  Under this method, the ratio of taxable
income earned during the period for which a distribution was made to total
income earned during the period determines the percentage of the distribution
designated taxable.  The percentages of income, if any, designated as taxable
will under this method vary from distribution to distribution.

     The Tax Reform Act of 1986 imposed a nondeductible excise tax on
regulated investment companies if they fail to satisfy certain minimum
distribution requirements.  This excise tax should not have a material
adverse effect on Fund operations, because the Fund intends to distribute all
of its net income each year.

     Although the Fund currently offers one class of shares at the date of
this Statement of Additional Information, the Fund's Trustees are authorized
to divide the shares into other separate series and classes, and to establish
additional portfolios pertaining to each series.  Each additional series of
shares would relate to a separate investment portfolio that would be
different from the Fund covered by this Statement of Additional Information. 
The Trust expects that it may create other separate state or regional
portfolios with investments concentrated in a particular state or region. 
The additional separate portfolios may be attractive for investors seeking to
concentrate their investments and to minimize their liability for state
income taxes on interest income earned by the respective portfolios or for
minimizing taxes on intangibles, depending upon the particular states. 
Separate series of the Trust will be treated under the Code as separate
corporations except with respect to the definitional requirements under
Section 851 (a) of the Code.  The legislative history of the Tax Reform Act
of 1986, which amended the Code, indicates that the term "fund" means a
segregated portfolio of assets, the beneficial interest of which is owned by
the holders of a class or series of stock of the regulated investment company
that is preferred over all other classes or series in respect of such
portfolio of assets.  The capital gains and losses of each series will belong
solely to the holders of the shares of that series and will not be aggregated
with the capital gains and losses of other series.  

<PAGE>     17

     As is the case with other types of income, including other tax-exempt
interest income, Exempt Interest Dividends received by an individual
shareholder will be added to his or her "modified adjusted gross income" in
determining what portion, if any, of the individual's Social Security
benefits will be subject to federal income taxation.  Shareholders are
advised to consult their own tax advisers as to the effect of this treatment.

     The Code treats interest on certain Municipal Obligations which are
private activity bonds under the Code issued after August 7, 1986 (in certain
cases, after September 1, 1986) as a preference item for purposes of the
alternative minimum tax on individuals and corporations.  The Fund may
purchase private activity bonds which are subject to treatment under the Code
as a preference item for purposes of the alternative minimum tax on
individuals and corporations, although the frequency and amounts of those
purchases are uncertain.  Some portion of Exempt Interest Dividends may, as
a result of such purchases, be treated as a preference item for purposes of
the alternative minimum tax on individuals and corporations.  Shareholders
are advised to consult their own tax advisers as to the extent and effect of
that treatment. 

     For taxable years beginning after 1989, the Code provides that the use
of adjusted net book income will be replaced by the use of adjusted current
earnings in computing corporate taxes.  The adjusted current earnings of a
corporation will include Exempt Interest Dividends in calculating the
alternative minimum tax on corporations to the extent that such Dividends are
not otherwise treated as a preference item for the reasons discussed above. 
Exempt Interest Dividends are included in effectively connected earnings and
profits for purposes of computing the branch profits tax on certain foreign
corporations doing business in the United States.

     Redemption or resale of shares will be a taxable transaction for federal
income tax purposes and the shareholder will recognize gain or loss in an
amount equal to the difference between the shareholder's basis in the shares
and the amount realized by the shareholder on the redemption or resale. 
Assuming that the shareholder holds the shares as a capital asset, the gain
or loss will be a capital gain or loss and will be long term if the shares
were held for more than 12 months.

     The foregoing is a general and abbreviated summary of the provisions of
the Code and Treasury Regulations presently in effect as they directly govern
the taxation of the Fund and its shareholders.  For complete provisions,
reference should be made to the pertinent Code sections and Treasury
Regulations.  The Code and Treasury Regulations are subject to change by
legislative or administrative action, and any such change may be retroactive
with respect to Fund transactions.  Shareholders are advised to consult their
own tax advisers for more detailed information concerning the federal
taxation of the Fund and the income tax consequences to shareholders of an
investment in the Fund.  In particular, prospective investors who are not
individuals are advised that the preceding discussion relates primarily to
tax consequences affecting individuals, and the tax consequences of an
investment by a person which is not an individual may be very different. 

<PAGE>     18

State and Local Tax Aspects

     Exempt Interest Dividends paid by the Fund and attributable to interest
received by the Fund on Municipal Obligations originating in New York will be
exempt from personal income taxes imposed by New York State and New York City
on individuals resident in the state and the city, respectively.  Exempt
Interest Dividends attributable to other Municipal Obligations, and dividends
attributable to interest on any taxable temporary investments and market
discount will not be exempt from those income taxes.  Net capital gains
distributions by the Fund, if any, will be subject to New York State and New
York City personal income taxes, and gains realized on share redemptions
similarly will be subject to these taxes.  Interest on indebtedness incurred
to purchase Fund shares will not be deductible in computing New York State
and New York City personal income taxes.  Prospective investors are urged to
confer with their tax advisers to determine the specific tax consequences of
their investment in Fund shares.  In particular, investors who are not
individuals should understand that the foregoing brief outline relates to
personal income taxes, and that a tax adviser should be consulted to
determine the tax consequences to those investors of holding Fund shares. 

Accounts of Shareholders

     When an investor makes an initial investment in shares of the Fund, the
Transfer Agent will open an account on the books of the Fund, and the
investor will receive a confirmation of the opening of the account. 
Thereafter, whenever a transaction, other than the reinvestment of interest
income, takes place in the account - such as a purchase of additional shares
or redemption of shares or a withdrawal of shares represented by certificates
- - the investor will receive a confirmation statement giving complete details
of the transaction.  Shareholders will also receive at least quarterly
statements setting forth all distributions of interest income and other
transactions in the account during the period and the balance of full and
fractional shares.  The final statement for the year will provide the
information for purposes described in the Prospectus under the caption
"Taxes."

     The monthly distributions of interest income, net of expenses, and the
annual distributions of net realized capital gains, if any, will be credited
to the accounts of shareholders in full and fractional shares of the Fund at
net asset value on the payment or distribution date, as the case may be.

     The issuance and delivery of certificates for shares is unnecessary, and
shareholders are thereby relieved of the responsibility of safekeeping.  Upon
written request to the Transfer Agent, a certificate will be issued for any
or all of the full shares credited to a shareholder's account.  Certificates
which have been issued to a shareholder may be returned at any time for
credit to his or her account.

        INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES AGREEMENTS

Investment Advisory Agreement

     Pursuant to the Investment Advisory Agreement for the Fund, Thornburg
Management Company, Inc., 119 East Marcy Street, Suite 202, Santa Fe, New
Mexico 87501 (TMC), will act as the investment adviser for, and will manage
the investment and reinvestment of the assets of the Fund in accordance with
its investment objectives and policies, subject to the general supervision
and control of the Fund's Trustees.

     TMC is investment adviser for Thornburg Limited Term Municipal Fund,
Inc., a series investment company with two fund series having aggregate
assets of approximately $1,030,602,000 as of June 30, 1996.  TMC also acts as
investment adviser for Thornburg Limited Term U.S. Government Fund, Thornburg
Limited Term Income Fund, Thornburg Intermediate Municipal Fund, Thornburg
New Mexico Intermediate Municipal Fund, Thornburg Florida Intermediate
Municipal Fund and Thornburg Value Fund, separate series of the Trust which
had assets of $142,299,000, $26,925,000, $254,402,000, $131,307,000,
$19,501,000 and $16,704,000, respectively, as of September 30, 1996.  TMC is
also a sub-adviser for Daily Tax-Free Income Fund, Inc., a registered
investment company.

     TMC will provide continuous professional investment supervision under
the Investment Advisory Agreement.  In addition to managing the Fund's
investments, TMC will administer the Fund's business affairs, provide office
facilities and certain related services.  Pursuant to the Investment Advisory
Agreement, the Fund will pay to TMC a monthly management fee at an annual
percentage rate displayed in the Prospectus.  All fees and expenses are
accrued daily and deducted before payment of dividends to investors.  In
addition to the investment management fee of TMC, the Fund will pay all other
costs and expenses of its operations.  The Fund also will bear the expenses
of registering and qualifying the Fund and the shares for distribution under
federal and state securities laws, including legal fees.

     The Investment Advisory Agreement was approved for the Fund on March 12, 
1997 by the Trustees of the Fund, including a majority of the Trustees who
are not "interested persons" (as defined in the 1940 Act) of the Fund or TMC,
and became effective for the Fund on June 6, 1997.  The initial term of this
Agreement is two years, with extensions for successive 12-month periods,
provided that the continuation for the Fund is approved at least annually by
a majority of the Trustees who are not "interested" within the meaning of the
Investment Company Act of 1940 or by a vote of the majority of the Fund's
shares then outstanding.  

     The Agreement may be terminated by either party, at any time without
penalty, upon 60 days' written notice, and will terminate automatically in
the event of its assignment.  Termination will not affect the right of TMC to
receive payments on any unpaid balance of the compensation earned prior to
termination.  The Agreement further provides that in the absence of willful
misfeasance, bad faith or gross negligence on the part of TMC, or of reckless
disregard of its obligations and duties under the Agreement, TMC will not be
liable for any action or failure to act in accordance with its duties
thereunder.

<PAGE>     20

Administrative Services Agreement

     Administrative services are provided to the sole class of shares issued
by the Fund under an Administrative Services Agreement which requires the
delivery of administrative functions necessary for the maintenance of the
shareholders of the class, supervision and direction of shareholder
communications, assistance and review in preparation of reports and other
communications to shareholders, administration of shareholder assistance,
supervision and review of bookkeeping, clerical, shareholder and account
administration and accounting functions, supervision or conduct of regulated
regulatory compliance and legal affairs, and review and administration of
functions delivered by outside service providers to or for shareholders, and
other related or similar functions as may from time to time be agreed.  The
Administrative Services Agreement specific to the Fund's sole class of shares
provides that the class will pay a fee calculated at an annual percentage of
 .125% of the class's average daily net assets, paid monthly, together with
any applicable sales or similar tax.  Services are currently provided under
these agreements by TMC.

     The agreement applicable to the class may be terminated by either party,
at any time without penalty, upon 60 days' written notice, and will terminate
automatically upon assignment.  Termination will not affect the service
provider's right to receive fees earned before termination.  The agreement
further provides that in the absence of willful misfeasance, bad faith or
gross negligence on the part of the service provider, or reckless disregard
of its duties thereunder, the provider will not be liable for any action or
failure to act in accordance with its duties thereunder.

     H. Garrett Thornburg, Jr., Chairman and a Trustee of the Trust, is also
a Director and controlling stockholder of TMC.

                               SERVICE PLAN

     The Fund has adopted a plan and agreement of distribution pursuant to
Rule 12b-1 under the Investment Company Act of 1940 ("Service Plan") which is
applicable to Class A shares of the Fund.  The Plan permits the Fund to pay
to TMC (in addition to the management fee and reimbursements described above)
an annual amount not exceeding .25 of 1% of the Fund's assets (plus any
applicable sales, use, gross receipts, value added or other tax) attributable
to the class of shares to reimburse TMC for specific expenses incurred by it
in connection with certain shareholder services and the distribution of that
class's shares to investors.  TMC may, but is not required to, expend
additional amounts from its own resources in excess of the currently
reimbursable amount of expenses.  Reimbursable expenses include the payment
of amounts, including incentive compensation , to securities dealers and
other financial institutions, including banks (to the extent permissible
under the Glass-Steagall Act and other federal banking laws), for
administration and shareholder services.  The nature and scope of services
provided by dealers and other entities likely will vary from entity to
entity, but may include, among other things, processing new account
applications, preparing and transmitting to the Transfer Agent computer
processable tapes of shareholder account transactions, and serving as a
source of information to customers concerning the Fund and transactions with

<PAGE>     21

the Fund.  The Service Plan does not provide for accrued but unpaid
reimbursements to be carried over and paid to TMC in later years.

     The Glass-Steagall Act prohibits certain banks from underwriting mutual
fund shares, but the Fund does not believe that this prohibition will apply
to the arrangements described in the Plan.  However, no assurance can be
given that the Glass-Steagall Act will not be interpreted so as to prohibit
these arrangements.  In that event, the Fund's ability to market its shares
could be impaired to a small extent.  The Fund does not foresee that it will
give preference to banks or other depository institutions which receive
payments from TMC when selecting investments for the Fund.

     The Plan continues in effect for periods of 12 months each unless
terminated pursuant to its terms and may be continued from year to year
thereafter, provided that the continuance is approved at lease annually by a
vote of a majority of the Trustees, including a majority of the independent
Trustees cast in person at a meeting called for the purpose of voting on such
continuance.  The Plan also may be terminated at any time, without penalty,
if a majority of the independent Trustees or shareholders of the Fund class
vote to terminate the Plan for that class.  So long as the Plan is in effect,
the selection and nomination of Trustees who are not "interested persons" of
the Fund shall be committed to the discretion of the Trustees who are not
"interested persons."  The Plan may not be amended to increase materially the
amount of the Fund's payments thereunder without approval of the shareholders
of the affected classes.  Under the Plan, the investment adviser or the
principal underwriter (as the case may be), or the Fund, by a vote of a
majority of the independent Trustees or of the holders of a majority of the
outstanding shares, may terminate the provisions retaining the services of
TMC under the Plan, without penalty.  The Trustees have the authority to
approve continuance of the Plan without similarly approving a continuance of
the provisions retaining TMC thereunder. 

     To the extent that the Plan constitutes a plan of distribution adopted
pursuant to Rule 12b-1 under the 1940 Act, it will remain in effect as such,
so as to authorize the use of the Fund's assets in the amounts and for the
purposes set forth therein, notwithstanding the occurrence of an assignment,
as defined by the 1940 Act and the rules thereunder.  To the extent it
constitutes an agreement pursuant to a plan, it will terminate automatically
in the event of an "assignment."  Upon termination, no further payments may
be made under the agreement except for amounts previously accrued by unpaid. 
The Fund may continue to make payments pursuant to the Plan of the amounts
authorized to be paid, which may or may not be to TMC or TSC, as the case may
be, or the adoption of other similar arrangements, in each case by the Fund's
Trustees, including a majority of the independent Trustees by vote cast in
person at a meeting called for that purpose.

     Information regarding the services rendered under the Plan and the
amounts paid therefor is provided to, and reviewed by, the Trustees on a
quarterly basis.

                          PORTFOLIO TRANSACTIONS

     TMC, in effecting purchases and sales of portfolio securities for the
accounts of the Fund, will place orders in such manner as, in the opinion of
TMC, will offer the best price and market for the execution of each

<PAGE>     22

transaction.  Securities normally will be purchased directly from an
underwriter or in the over-the-counter market from the principal dealers in
such securities, unless it appears that a better price or execution may be
obtained elsewhere.  Purchases from underwriters will include a commission or
concession paid by the issuer to the underwriter, and purchases from dealers
will include the spread between the bid and asked price.  Given the best
price and execution obtainable, it will be the practice of the Fund to select
dealers which, in addition, furnish research information (primarily credit
analyses of issuers) and statistical and other services to TMC.  It is not
possible to place a dollar value on information and statistical and other
services received from dealers.  Since it is only supplementary to TMC's own
research efforts, the receipt of research information is not expected
significantly to reduce TMC's expenses.  In selecting among the firms
believed to meet the criteria for handling a particular transaction, TMC may
also give consideration to those firms which have sold or are selling shares
of the Fund.  While TMC will be primarily responsible for the placement of
the Fund's business, the policies and practices of TMC in this regard must be
consistent with the foregoing and will at all times be subject to review by
the Trustees of the Fund.

     TMC reserves the right to manage other investment companies and
investment accounts for other clients which may have investment objectives
similar to those of the Fund.  Subject to applicable laws and regulations,
TMC will attempt to allocate equitably portfolio transactions among the Fund
and the portfolios of its other clients purchasing securities whenever
decisions are made to purchase or sell securities by the Fund and one or more
of such other clients simultaneously.  In making such allocations the main
factors to be considered will be the respective investment objectives of the
Fund and such other clients, the size of investment commitments generally
held by the Fund and such other clients and opinions of the persons
responsible for recommending investments to the Fund and such other clients. 
While this procedure could have a detrimental effect on the price or amount
of the securities available to the Fund from time to time, it is the opinion
of the Fund's Trustees that the benefits available from TMC's organization
will outweigh any disadvantage that may arise from exposure to simultaneous
transactions.  The Trustees will review simultaneous transactions.

                   MANAGEMENT AND HOLDERS OF SECURITIES

     The management of the Fund, including general supervision of the duties
performed by TMC under the Investment Advisory Agreement, is the
responsibility of its Trustees.  There are six Trustees, two of whom are
"interested persons."  The names of the Trustees and officers and their
principal occupations and other affiliations during the past five years are
set forth below, with the Trustees who are "interested persons" of the Fund
indicated by asterisks:

                        HOW TO PURCHASE FUND SHARES

     Procedures with respect to the manner in which shares of the Fund may be
purchased and how the offering price is determined are set forth in the
Prospectus under the caption "BUYING FUND SHARES IN GENERAL."

     The Prospectus states that certain classes of investors, specified
below, may purchase shares of the Fund at variations to the Public Scale. 
The Trust may change or eliminate these variations at any time.

     (1)   Existing shareholders of the Fund may purchase shares upon the
reinvestment of dividends and capital gains distributions with no sales
charge.  This practice is followed by many investment funds that charge sales
loads for new investments.

     (2)   Shareholders of the Fund who have redeemed all or any portion of
their investment in shares of the Fund may purchase shares with no sales
charge up to the maximum dollar amount of their shares redeemed within 24
months of the redemption date, provided that the shareholder's dealer or the
shareholder must notify TSC or the Transfer Agent at the time an order is
placed that such a purchase would qualify for this variation to the Public
Scale.  Similar notifications must be made in writing by the dealer, the
broker, or the shareholder when the order is placed by mail.  The sales
charge will not be eliminated if notification is not furnished at the time of
the order or a review of TSC's or the Transfer Agent's records fail to
confirm the investor's represented previous holdings. 

     (3)   Persons may purchase shares of the Fund at no sales charge if they
redeem shares of the Fund or Class A shares of any other series of Thornburg
Investment Trust, or of any series of Thornburg Limited Term Municipal Fund,
Inc., and reinvest some or all of the proceeds within 24 months.  The
shareholder's dealer or the shareholder must notify TSC or the Transfer Agent
at the time an order is placed that the purchase qualifies for this variation
to the Public Scale.

     The special classes of shareholders in subsections (2) and (3) above
were created as a convenience for those shareholders who invest in the Fund
and subsequently make a decision to redeem all or part of their investment
for a temporary period.  In some cases, the existence of this special class
of shareholders will act as further inducement for certain individuals to
make an initial investment in the Fund, particularly if those investors feel
that they might have a temporary need to redeem all or part of their
investment in the coming years.  Shareholders who have previously invested in
funds managed by TMC are more familiar than the general public with the Fund,
its investment objectives, and its results.  The costs to TSC of its
marketing to these individuals and maintaining the records of their prior
investment are minimal compared to the costs of marketing the Fund to the
public at large.

     (4)   Officers, Trustees, directors and employees of the Trust, TMC,
TSC, the Custodian and Transfer Agent, and counsel to the Trust, and members
of their families, including trusts for the benefit of the foregoing, may
purchase shares of the Fund with no sales charge, provided that they notify
TSC or the Transfer Agent at the time an order is placed that a purchase will

<PAGE>     26

qualify for this variation from the Public Scale.  The sales charge will not
be eliminated if the notification is not furnished at the time of the order
or a review of Fund records fails to confirm that the investor's
representation is correct.  The reduced sales charge to these persons is
based upon the Trust's view that their familiarity with and loyalty to the
Fund will require less selling effort by the Fund, such as a solicitation and
detailed explanation of the conceptual structure of the Fund, and less
sales-related expenses, such as advertising expenses, computer time, paper
work, secretarial needs, postage and telephone costs, than are required for
the sale of shares to the general public.  Inclusion of the families of these
persons is based upon the Trust's view that the same economies exist for
sales of shares to family members.

     (5)   Employees of brokerage firms who are members in good standing with
the National Association of Securities Dealers, Inc. ("NASD"), employees of
financial planning firms who place orders for the Fund placed directly with
the Transfer Agent or TSC and through a broker/dealer who is a member in good
standing with the NASD, and employees of eligible non-NASD members which
accept orders for shares of the Fund on an agency basis and clear those
orders through a broker/dealer who is a member in good standing with NASD,
and their families, including trusts for the benefit of the foregoing, may
purchase shares of the Fund for themselves with no sales charge, provided
that (i) the order must be through a NASD member firm which has entered into
an agreement with TSC to distribute shares of the Fund, and (ii) the
shareholder's broker/dealer or the shareholder must notify TSC or the
Transfer Agent at the time an order is placed that the purchase would qualify
for this variation to the Public Scale.  Similar notification must be made in
writing by the dealer, the broker, or the shareholder when such an order is
placed by mail.  The reduced sales charge will not apply if the notification
is not furnished at the time of the order or a review of TSC's, the dealer's,
the broker's or the Transfer Agent's records fails to confirm that the
investor's representation is correct.

     Because they sell the Fund's shares, these individuals tend to be much
more aware of the Fund than the general public.  Any additional costs to TSC
of marketing to these individuals are minimal.

     (6) Bank trust departments, companies with trust powers and investment
dealers and investment advisors who charge fees for service, and investment
dealers who utilize wrap fee and similar arrangements may purchase shares of
the Fund for their customers at no sales charge, provided that these persons
notify TSC or the Transfer Agent, at the time an order qualifying for this
reduced charge is placed, that such a purchase would qualify for this
variation to the Public Scale.

     (7) Purchases of shares of the Fund may be made at net asset value
provided that such purchases are placed through a broker that maintains one
or more omnibus accounts with the Fund and such purchases are made by (i)
investment advisers or financial planners who place trades for their own
accounts or the accounts of their clients and who charge a management,
consulting or other fee for their services; (ii) clients of such investment
advisers or financial planners who place trades for their own accounts if the
accounts are linked to the master account of such investment adviser or
financial planner on the books and records of the broker or agent; and (iii)
retirement and deferred compensation plans and trusts used to fund those
plans, including, but not limited to, those defined in Sections 401(a)

<PAGE>     27

through 403(b) or 457 of the Internal Revenue Code and "rabbi trusts." 
Investors may be charged a fee if they effect transactions in Fund shares
through a broker or agent.

     These organizations may charge fees to clients for whose accounts they
purchase shares of the Fund in a fiduciary capacity.  Where the reduced sales
charge applies, notification is required at the time the order is received,
and a review of TSC's or Transfer Agent's records must confirm that the
investor's representation is correct.

     (8)   No sales charge will be payable at the time of purchase on
investments of $1 million or more made by a purchaser.  A contingent deferred
sales charge ("CDSC") will be imposed on these investments in the event of a
share redemption within one year following the share purchase at the rate of
1/2 of 1% of the value of the shares redeemed.  In determining whether a CDSC
is payable and the amount of any fee, it is assumed that shares not subject
to the charge are the first redeemed, followed by other shares held for the
longest period of time.  The applicability of these fees will be unaffected
by transfers of registration.  TSC or TMC intend to pay a commission of up to
1/2 of 1% to dealers who place orders of $1 million or more for a single
purchaser.

     The investment decisions of the persons and organizations described in
the preceding paragraph tend to be made by informed advisers.  Typically,
these persons are better able than the general public to evaluate quickly the
appropriateness of the Fund's investment objectives and performance in light
of their customers' goals.  Costs of marketing to these persons and
organizations likely will be minimal.

      (9)  Such persons as are determined by the Trustees to have acquired
shares under special circumstances, not involving any sales expense to the
Fund or to TSC, may purchase shares of the Fund with no sales charge.  This
variation from the Public Scale contemplates circumstances where a relatively
large sale can be made at no distribution cost to a large investor or a
number of smaller investors who are similarly situated.  In the contemplated
circumstances, there would be no cost of distribution, or any costs would be
paid by TMC.

     (10)  Shares of the Fund may be sold at a reduced or no sales charge
pursuant to sponsored arrangements, which include programs under which an
organization makes recommendations to or permits group solicitation of its
employees, members or participants.  Information on these arrangements is
available from TSC. 


                              NET ASSET VALUE

     Procedures for determining the net asset value of the Fund's shares are
set forth in the Prospectus.

     The Fund will calculate the net asset value at least once daily on days
when the New York Stock Exchange is open for trading, and more frequently if
deemed desirable by the Trust.  Net asset value will not be calculated on New
Year's Day, Washington's Birthday (on the third Monday in February), Good
Friday, Memorial Day (on the last Monday in May), Independence Day, Labor

<PAGE>     28

Day, Thanksgiving Day, Christmas Day, on the preceding Friday if any of the
foregoing holidays falls on a Saturday, and on the following Monday if any of
the foregoing holidays falls on a Sunday.  Under the Investment Company Act
of 1940, net asset value must be computed at least once daily on each day
(i) in which there is a sufficient degree of trading in the Fund's portfolio
securities that the current net asset value of its shares might be materially
affected by changes in the value of such securities and (ii) on which an
order for purchase or redemption of its shares is received.

                           REDEMPTION OF SHARES

     Procedures with respect to redemption of Fund shares are set forth in
the Prospectus under the caption "Selling Fund Shares."

     The Fund may suspend the right of redemption or delay payment more than
seven days (a) during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), (b) when trading in the
markets the Fund normally utilize is restricted, or an emergency exists as
determined by the Securities and Exchange Commission so that disposal of the
Fund's investments or determination of its net asset value is not reasonably
practicable, or (c) for such other periods as the Securities and Exchange
Commission by order may permit for protection of the shareholders of the
Fund.

                                DISTRIBUTOR

     Pursuant to a Distribution Agreement with the Trust, Thornburg
Securities Corporation acts as the principal underwriter of Fund shares.  The
Fund does not bear selling expenses except (i) those involved in registering
shares with the Securities and Exchange Commission and qualifying them or the
Fund with state regulatory authorities, and (ii) expenses paid under the
Service Plan which might be considered selling expenses.  Terms of
continuation, termination and assignment under the Distribution Agreement are
identical to those described above with regard to the Investment Advisory
Agreement, except that termination other than upon assignment requires six
months' notice. 

     H. Garrett Thornburg, Jr. President, Treasurer and a Trustee of the
Trust, is also Director and controlling stockholder of TSC.

                           INDEPENDENT AUDITORS

     McGladrey & Pullen, LLP, 555 Fifth Avenue, New York, New York 10017, is
the independent auditor of the Fund for the fiscal year ending September 30,
1997.  Shareholders will receive semi-annual unaudited financial statements,
and annual financial statements audited by the independent auditors.
