Letter to shareholders

Dear Fellow Shareholder,
The fiscal year ending  September  30, 1999  continued a period of change in the
bond market.  After  falling to their lowest  levels in several years in October
1998, interest rates have risen steadily throughout 1999. The net asset value of
the A shares  decreased 76 cents per share to $13.00 over the year.  If you were
with us for the entire period,  you received dividends of 62 cents per share. If
you reinvest your  dividends,  you received  63.2 cents per share.  For the year
ended September 30, investors who owned C shares received  dividends of 56.5 and
57.6 cents per share,  respectively.  Your fund is a managed bond portfolio. Its
performance  over the last year is a total of all the stories of the  individual
bonds in our portfolio plus a few that we traded during the period.  One typical
story pertains to our investment in $1,880,000 of the Noblesville,  Indiana High
School Building  Corporation  bonds due 1/5/2007.  This is a AAA-rated,  insured
bond from an A-rated school district.  The graph on this page compares the price
change of  Thornburg  Intermediate  Municipal  Fund with the price change in the
Noblesville  School bond.  Note: This graph considers market price changes only,
not total return. On September 30, 1998 this bond was worth 111.46% of its $1.88
million  maturity  amount at a then market yield of 4.10%. On September 30, 1999
an increase in its market yield to 4.92% decreased the price of the bond to 105%
of its maturity  value. In general,  the price  volatility of your fund was less
than that of the single Noblesville bond.


Nothing has happened in the last several years of fluctuating  interest rates to
change the ultimate  maturity value of this bond, or most of the other bonds you
own through your investment in this fund.  What has changed?  The interim market
prices of these bonds moved lower  through  most of 1999,  with the shortest and
highest quality bonds performing best. If interest rates drop in the future, the
longest bonds in the portfolio will perform best.  Your portfolio  includes over
400 bonds  from 48 states  and 2 U.S.  territories,  85% of which are rated A or
better by one of the major  rating  agencies.  Your bond  portfolio in Thornburg
Intermediate  Municipal  Fund is  laddered  to give a  dollar  weighted  average
maturity of  approximately  8.5 years.  This is shorter than the 10 year maximum
average  maturity for your fund.  Percentages  of the portfolio  maturing in the
coming years are summarized below:

         % of portfolio    Cumulative %
         maturing within   maturing by end of
         2 years = 6%      year 2 = 6%
    2 to 4 years = 11%     year 4 = 17%
    4 to 6 years = 15%     year 6 = 32%
    6 to 8 years = 17%     year 8 = 49%
   8 to 10 years = 12%     year 10 = 61%
  10 to 12 years = 12%     year 12 = 73%
  12 to 14 years = 13%     year 14 = 86%
  14 to 16 years = 7%      year 16 = 93%
  16 to 18 years = 5%      year 18 = 98%
   Over 18 years = 2%

Over the years, our practice of laddering a diversified portfolio of short and
 intermediate maturity bonds has allowed your fund to consistently perform well
in varying interest rate environments. Your fund has earned Morningstar's
4-star overall rating* for risk adjusted performance. We would like to attribute
 this to capable execution of a sensible investment strategy over time. Thank
you for investing in Thornburg Intermediate Municipal Fund.
Sincerely,


Brian J. McMahon  George T. Strickland

Notes to financial statements
Note 1 - Organization
Thornburg  Intermediate  Municipal Fund (the "Fund"), is a diversified series of
Thornburg  Investment  Trust  (the  "Trust").   The  Trust  is  organized  as  a
Massachusetts business trust under a Declaration of Trust dated June 3, 1987 and
is registered as a diversified, open-end management investment company under the
Investment Company Act of 1940, as amended. The Trust is currently issuing seven
series  of shares  of  beneficial  interest  in  addition  to those of the Fund:
Thornburg Florida  Intermediate  Municipal Fund, Thornburg New York Intermediate
Fund,  Thornburg New Mexico Intermediate  Municipal Fund, Thornburg Limited Term
U.S. Government Fund,  Thornburg Limited Term Income Fund, Thornburg Value Fund,
and  Thornburg  Global Value Fund.  Each series is  considered  to be a separate
entity for financial reporting and tax purposes. The Fund's investment objective
is to obtain as high a level of current  income exempt from Federal income taxes
as is consistent  with the  preservation of capital.  The Fund currently  offers
three  classes  of  shares  of  beneficial  interest,   Class  A,  Class  C  and
Institutional  Class (Class I) shares. Each class of shares of a Fund represents
an interest in the same portfolio of  investments  of the Fund,  except that (i)
Class A shares are sold  subject to a front-end  sales  charge  collected at the
time the shares are  purchased  and bear a service fee,  (ii) Class C shares are
sold at net asset value without a sales charge at the time of purchase,  but are
subject to a service fee and a  distribution  fee, (iii) Class I shares are sold
at net asset value without a sales charge at the time of purchase,  and (iv) the
respective classes have different reinvestment  privileges.  Additionally,  each
Fund may allocate among its classes certain expenses, to the extent allowable to
specific classes,  including transfer agent fees, government  registration fees,
certain  printing and postage  costs,  and  administrative  and legal  expenses.
Currently, class specific expenses of the Fund are limited to distribution fees,
administrative fees and certain transfer agent expenses.

Note 2 - Significant  Accounting Policies Significant accounting policies of the
Fund are as follows:
Valuation of Investments:  In determining net asset value,  the Fund utilizes an
independent pricing service approved by the Trustees. Debt investment securities
have a primary market over the counter and are valued on the basis of valuations
furnished  by  the  pricing  service.   The  pricing  service  values  portfolio
securities  at quoted  bid prices at 4:00 pm EST or the yield  equivalents  when
quotations are not readily  available.  Securities for which  quotations are not
readily  available are valued at fair value as determined by the pricing service
using  methods  which  include  consideration  of yields or prices of  municipal
obligations of comparable quality, type of issue, coupon,  maturity, and rating;
indications  as to  value  from  dealers  and  general  market  conditions.  The
valuation  procedures used by the pricing  service and the portfolio  valuations
received by the Fund are reviewed by the officers of the Trust under the general
supervision of the Trustees.  Short-term obligations having remaining maturities
of 60 days or less are  valued at  amortized  cost,  which  approximates  market
value.  Federal  Income  Taxes:  It is the policy of the Fund to comply with the
provisions of the Internal  Revenue Code  applicable  to  "regulated  investment
companies"  and to distribute  all of its taxable (if any) and tax exempt income
to its shareholders.  Therefore no provision for Federal income tax is required.
Dividends  paid by the Fund for the year  ended  September  30,  1999  represent
exempt interest dividends which are excludable by shareholders from gross income
for Federal income tax purposes.  Net realized capital losses are caried forward
to  offset  realized   capital  gains  in  future  years.  To  the  extent  such
carryforwards are used, no capital  distributions will be made.  When-Issued and
Delayed  Delivery  Transactions:  The Fund may engage in  when-issued or delayed
delivery transactions.  To the extent the Fund engages in such transactions,  it
will do so for the purpose of acquiring portfolio securities consistent with its
investment  objectives  and not for the  purpose of  investment  leverage  or to
speculate on interest rate  changes.  At the time the Fund makes a commitment to
purchase a security on a when-issued  basis,  it will record the transaction and
reflect  the value in  determining  its net asset  value.  When  effecting  such
transactions, assets of the Fund of an amount sufficient to make payment for the
portfolio securities to be purchased will be segregated on the Fund's records at
the trade date.  Securities purchased on a when-issued or delayed delivery basis
do not earn interest until the settlement date. Dividends: Net investment income
of the Fund is  declared  daily as a  dividend  on shares for which the Fund has
received  payment.  Dividends are paid monthly and are  reinvested in additional
shares of the Fund at 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 capital
gains,  to  the  extent  available,  will  be  distributed  annually.   General:
Securities transactions are accounted for on a trade date basis. Interest income
is accrued as earned.  Premiums  and  original  issue  discounts  on  securities
purchased are amortized  over the life of the  respective  securities.  Realized
gains and losses from the sale of securities are recorded on an identified  cost
basis. Use of Estimates: The preparation of financial statements,  in conformity
with  generally  accepted  accounting  principles,  requires  management to make
estimates  and  assumptions  that  affect  the  reported  amounts  of assets and
liabilities and the disclosure of contingent  assets and liabilities at the date
of the financial  statements and the reported amounts of increases and decreases
in net assets from operations during the reporting period.  Actual results could
differ from those estimates.

Note 3 - Investment Advisory Fee and Other Transactions With Affiliates
Pursuant to an investment advisory agreement,  Thornburg Investment  Management,
Inc. (the "Adviser") serves as the investment  adviser and performs services for
which  the  fees  are  payable  at the end of each  month.  For the  year  ended
September 30, 1999,  these fees were payable at annual rates ranging from 1/2 of
1% to 11/40 of 1% of the average  daily net assets of the Fund  depending on the
Fund's asset size. The Fund also has an Administrative  Services  Agreement with
the Adviser,  whereby the Adviser will perform certain  administrative  services
for the shareholders of each class of the Fund's shares, and for which fees will
be payable at an annual rate of up to 1/8 of 1% of the average  daily net assets
attributable to each class of shares. For the year ended September 30, 1999, the
Adviser voluntarily reimbursed certain operating expenses amounting to $132,097.
The Fund has an  underwriting  agreement with Thornburg  Securities  Corporation
(the  "Distributor"),  which acts as the Distributor of the Fund shares. For the
year ended September 30, 1999, the Distributor  earned  commissions  aggregating
$55,228 from the sale of Class A shares and collected  contingent deferred sales
charges  aggregating  $11,875  from  redemptions  of Class C shares of the Fund.
Pursuant to a Service Plan,  under Rule 12b-1 of the  Investment  Company Act of
1940,  the Fund may  reimburse  to the Adviser an amount not to exceed .25 of 1%
per annum of the average net assets  attributable to each class of shares of the
Fund for payments made by the Adviser to securities  dealers and other financial
institutions to obtain various shareholder related services. The Adviser may pay
out of its own funds additional  expenses for distribution of the Fund's shares.
The Fund has also adopted a Distribution Plan pursuant to Rule 12b-1, applicable
only to the  Fund's  Class  C  shares  under  which  the  Fund  compensates  the
Distributor  for services in promoting the sale of Class C shares of the Fund at
an annual rate of up to .75% of the  average  daily net assets  attributable  to
Class C shares.  Total fees  incurred  by each class of shares of the Fund under
their respective  Service and Distribution Plans and the total amount waived for
the year ended September 30, 1999, are set forth in the statement of operations.
Certain officers and trustees of the Trust are also officers and/or directors of
the Adviser and Distributor.  The compensation of unaffiliated trustees is borne
by the Trust.

Note 4 - Shares of Beneficial Interest At September 30, 1999 there
were an  unlimited  number of  shares of  beneficial  interest  authorized,  and
capital paid in aggregated  $416,761,877.  Transactions  in shares of beneficial
interest were as follows:

Report of Independent accountants

To the Board of Trustees and  Shareholders of Thornburg  Investment Trust In our
opinion,  the accompanying  statement of assets and  liabilities,  including the
schedule of investments, and the related statements of operations and of changes
in net assets and the  financial  highlights  present  fairly,  in all  material
respects, the financial position of Thornburg Intermediate Municipal Fund series
of Thornburg Investment Trust (hereafter referred to as the "Fund") at September
30, 1999, the results of its operations,  the changes in its net assets, and the
financial  highlights  for the year then ended,  in  conformity  with  generally
accepted  accounting  principles.   These  financial  statements  and  financial
highlights   (hereafter   referred  to  as  "financial   statements")   are  the
responsibility  of the Fund's  management;  our  responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these  financial  statements in accordance with generally  accepted  auditing
standards, which require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the  amounts  and  disclosures  in  the  financial  statements,   assessing  the
accounting  principles  used and significant  estimates made by management,  and
evaluating the overall  financial  statement  presentation.  We believe that our
audit,  which  included  confirmation  of  securities  at September  30, 1999 by
correspondence  with the custodian and brokers,  provides a reasonable basis for
the  opinion  expressed  above.  The  financial  statements  for the year  ended
September  30, 1998,  including the  financial  highlights  for each of the four
years in the period then ended,  were audited by other  independent  accountants
whose report dated October 23, 1998  expressed an  unqualified  opinion on those
financial statements.  PricewaterhouseCoopers LLP New York, New York October 29,
1999

change in Independent accountants

Thornburg Investment Trust
On August 13, 1999,  McGladrey & Pullen, LLP (McGladrey) resigned as independent
auditors of the Fund  pursuant to an  agreement  by  PricewaterhouseCoopers  LLP
(PwC) to acquire McGladrey's investment company practice. The McGladrey partners
and  professionals  serving the Fund at the time of the acquisition  joined PwC.
The reports of McGladrey on the financial statements of the Fund during the past
two fiscal years contained no adverse opinion or disclaimer of opinion, and were
not  qualified  or  modified  as  to  uncertainty,  audit  scope  or  accounting
principles.  In connection  with its audits for the two most recent fiscal years
and through August 13, 1999, there were no  disagreements  with McGladrey on any
matter of accounting principle or practices,  financial statement disclosure, or
auditing  scope  or  procedure,  which  disagreements,  if not  resolved  to the
satisfaction  of McGladrey would have caused it to make reference to the subject
matter of disagreement in connection with its report. On September 22, 1999, the
Fund,  with the  approval  of its Board of  Directors  and its Audit  Committee,
engaged PwC as its independent auditor.

Y2k Update
We Are Ready for the Year 2000

Dear Shareholder,

I wish to inform you about our success with respect to being Year 2000 compliant
in the computer  systems used to manage your Thornburg  funds  investment.  Your
shareholder  records  are  kept  on a large  computer  system  belonging  to our
transfer  agent,  DST Systems.  Accounting  data  pertaining to your  investment
portfolio  reside  on  large  systems  belonging  to State  Street  Bank and its
affiliates. We have smaller computer networks at Thornburg Investment Management
to help us  organize  and  manage our  investment  activities.  I will  describe
briefly the Year 2000 status of each area.

Shareholder  records for  Thornburg  funds are kept on computers  that use a DST
software  system called "TA 2000." DST is one of the largest  mutual fund record
processors in the world,  keeping shareholder records for many large mutual fund
families.  The TA 2000 system,  as is name implies,  was built with 4-digit year
description  fields  in order to be Year 2000  compliant.  To quote  from  DST's
February 1999  newsletter,  "Internal 2000 readiness  testing of TA 2000 and TRA
2000 is complete.  Several retests of critical TA 2000 (and TRAC 2000) functions
were also completed  successfully in 1998. With the completion of these internal
tests,  the TA 2000 (and TRAC 2000)  systems  are  considered  to be Y2K ready."
There are no hedge words in the preceeding 3 sentences!  I am not  surprised.  I
first  heard DST talk about  taking  concrete  measures  to deal with Y2K issues
about 8 years ago. If you worry about  electric power  continuity,  I can inform
you that DST maintains its own diesel powered backup generating station adjacent
to its computer facility.
Both are located in geologically stable limestone caves east of Kansas City.

Asset custody and fund  accounting  records of the Thornburg funds are stored on
State Street Bank computers.  We use a variety of software  systems to carry out
all activities relating to running the funds. We are informed that this software
infrastructure has been 100% tested and corrected to be Year 2000 compliant. You
can monitor State Street  Bank's  disclosure  yourself on the internet  website,
statestreet.com.

Thornburg Investment  Management has a computer network to help us carry out our
daily  business  of managing  the assets in our mutual  funds.  Our  information
technology  director,  Stewart Kane,  has made a great effort to be certain that
our software platforms are Year 2000 compliant.

We look forward to the new year.
