SMITH BARNEY MASSACHUSETTS MUNICIPALS FUND
================================================================================

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney
Massachusetts Municipals Fund ("Fund") for the period ended May 31, 1997. In
this report, we summarize the period's prevailing economic and market conditions
and outline our portfolio strategy. A detailed summary of the Fund's performance
can be found in the appropriate sections that follow.

For the six months ended May 31, 1997, the Class A shares of the Massachusetts
Municipals Fund had a total return of 1.78%. In comparison, the average for
Massachusetts tax-exempt funds was 1.42% for the same period according to Lipper
Analytical Services, Inc. (Lipper Analytical Services, Inc. is an independent
fund tracking organization.) During the six months covered by this report, the
Fund distributed income dividends totaling $0.34 per Class A share; based on its
net asset value (NAV) of $12.88 as of May 31, 1997 and a current dividend rate
of $0.056 per share, this equates to annualized distribution rate of 5.22%. For
a Massachusetts state resident in the combined federal and state tax bracket of
43.68%, the tax-free yield of 5.22% is equivalent to a taxable yield of 9.27%.
(This figure assumes an investor is in the federal tax bracket of 36%, which
constitutes 10% of all U.S. taxpayers according to the Internal Revenue
Service.)

Market and Economic Overview

During the past year, the U.S. economy has continued to grow steadily. Although
the U.S. unemployment rate is near a thirty-year low and consumer confidence is
the highest it has been in over twenty years, there has not been a substantial
increase in inflationary pressures. Nevertheless, lower unemployment and rising
production costs prompted the Federal Reserve Board ("Fed") to raise the federal
funds rate by 25 basis points, or 0.25%, in late March of this year. (The
federal funds rate is the interest rate banks charge each other for overnight
loans and a closely watched indicator of the direction of interest rates.) The
Fed has indicated that it prefers to head off any possible increase in inflation
with a preemptive action rather than wait for any inflationary pressures to
build.

While the Fed action was widely anticipated, the likelihood of a rise in
interest rates added to the significant market volatility that occurred during
the year. The potential tightening of Fed monetary policy raised investor
concerns over the U.S. equity market's ability to sustain the now seven-year
bull market. In

                                                                             1

our opinion, higher equity market volatility, along with continued speculation
on Fed monetary policy, led many investors to gravitate toward the relative
safety of the bond market.

At its May 20, 1997 meeting, the Fed chose not to raise interest rates further,
reflecting its view that the U.S. economy could continue to grow at its present
pace without increased inflationary pressures. Moreover, recently released
government reports revealed a dramatic decline in consumer spending in the
second quarter of this year. We believe that this economic growth with little or
no inflationary pressure should provide a positive environment for municipal
bonds over the coming months.

Massachusetts Economic Highlights

Governor William Weld believes that over the last six years his administration
has been responsible for turning the Commonwealth of Massachusetts' economy
around. When Governor Weld was first elected, Massachusetts was in very bad
shape fiscally. In July 1991, unemployment in the Commonwealth stood at nearly
9.6% and manufacturing was in a ten-year decline. Today, the state's fiscal
situation has improved dramatically. Since 1991, taxes have been cut fifteen
times and the burden on taxpayers has been reduced by more than $1 billion.
Moreover, with more than 320,000 new jobs created during the past six years, job
growth in Massachusetts remains strong. In fact, Massachusetts currently has the
lowest unemployment rate of any large industrial state. In our view, all of
these extremely positive developments underscore real progress. To his credit,
Governor Weld, has made Massachusetts a more hospitable place for both
businesses and taxpayers and the state continues to maintain relatively high
credit ratings from the major credit reporting agencies.

Looking ahead, we expect moderate economic growth in Massachusetts under
Governor Weld's administration and we remain generally positive about the
state's economic future. In recent years, the economy of Massachusetts has been
distinguished by strong growth in non-banking finance as well as continuing
strong demand for high-tech products, particularly in the communications,
software and networking industries that have historically been attracted to the
state because of its renowned research universities and educated work force.

Fund's Investment Strategy

The Smith Barney Massachusetts Municipals Fund's investment strategy continues
to emphasize higher coupon bonds in order to provide a competitive level of
income exempt from federal and Massachusetts state income taxes. In addition, we
strive to maintain a high quality portfolio. As of May 31, 1997, over 94% of the
Fund's holdings were rated investment grade or better, of

2
<PAGE>
 
which 57% were rated AAA/Aaa by either Standard & Poor's Ratings Service or
Moody's Investors Service Inc. (Standard & Poor's Ratings Service and Moody's
Investors Service Inc. are two major credit reporting and bond rating agencies.)
In addition, as of May 31, 1997, the Fund's top three sectors were: general
obligation bonds (20.8%), hospital bonds (19.4%) and education bonds (18.8%).

Municipal Bond Market Outlook

We remain positive on the prospects for Massachusetts municipal bonds in the
coming year. The U.S. economy appears to be continuing along its present path of
moderate growth without any meaningful rise in inflation. However, a substantial
pickup in economic activity in the third quarter of this year could trigger a
Fed response, prompting it to tighten the money supply once again. Moreover, the
Massachusetts economy appears to be recovering from the recession that has
plagued many Northeastern states. The ongoing efforts to streamline the state
government have resulted in a state budget surplus for the first time in years.
We expect that municipal bond issuance in Massachusetts should remain relatively
light and that should also help to support municipal bond prices.

In closing, thank you for your investment in the Smith Barney Massachusetts
Municipals Fund. We look forward to helping you achieve your investment goals.

Sincerely,

/s/ Heath B. McLendon                           /s/ Lawrence T. McDermott

+ Hypothetical illustration of $10,000 invested in Class A shares at inception
  on December 21, 1987, assuming deduction of the maximum 4.00% sales charge at
  the time of investment and reinvestment of dividends and capital gains, if
  any, at net asset value through May 31, 1997. The Lehman Municipal Bond Fund
  Index is a broad based, total return index comprised of 8,000 actual bonds
  which are all investment grade, fixed rate, long term maturities (greater than
  two years) and are selected from issues larger than $50 million dated since
  January 1984. The index is unmanaged and is not subject to the same management
  and trading expenses as a mutual fund. The Lipper Massachusetts Municipal Fund
  Average is composed of the Fund's peer group of mutual funds (50 funds as of
  May 31, 1997). The performance of the Fund's other classes may be greater or
  less than the Class A shares' performance indicated on this chart, depending
  on whether greater or lesser sales charges and fees were incurred by
  shareholders investing in the other classes.

  All figures represent past performance and are not a guarantee of future
  results. Investment returns and principal value will fluctuate, and redemption
  values may be more or less than the original cost. No adjustment has been made
  for shareholder tax liability on dividends or capital gains.

Bond Ratings
================================================================================

All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"),
except those identified by an asterisk (*) are rated by Moody's Investors
Service, Inc. ("Moody's"). The definitions of the applicable rating symbols are
set forth below:

Standard & Poor's -- Ratings from "AA" to "B" may be modified by the addition of
a plus (+) or minus (-) sign to show relative standings within the major rating
categories.
<TABLE>
<S>       <C> 
AAA      --  Bonds rated "AAA" have the highest rating assigned by Standard &
             Poor's. Capacity to pay interest and repay principal is extremely
             strong.
AA       --  Bonds rated "AA" have a very strong capacity to pay interest and
             repay principal and differs from the highest rated issue only in a
             small degree.
A        --  Bonds rated "A" have a strong capacity to pay interest and repay
             principal although it is somewhat more susceptible to the adverse
             effects of changes in circumstances and economic conditions than
             bonds in higher rated categories.
BBB      --  Bonds rated "BBB" are regarded as having an adequate capacity to
             pay interest and repay principal. Whereas they normally exhibit
             adequate protection parameters, adverse economic conditions or
             changing circumstances are more likely to lead to a weakened
             capacity to pay interest and repay principal for bonds in this
             category than in higher rated categories.
BB       --  Bonds rated "BB" have less near-term vulnerability to default than
             other speculative issues. However, they face major ongoing
             uncertainties or exposure to adverse business, financial, or
             economic conditions which could lead to inadequate capacity to meet
             timely interest and principal payments.
B        --  Bonds rated "B" have a greater vulnerability to default but
             currently have the capacity to meet interest payments and principal
             payments. Adverse business, financial, or economic conditions will
             likely impair capacity or willingness to pay interest and repay
             principal. The "B" rating category is also used for debt
             subordinated to senior debt that is assigned an actual or implied
             "BB" or "BB-" rating.

Moody's  --  Numerical modifiers 1, 2 and 3 may be applied to each generic
rating from "Aa" to "Ba," where 1 is the highest and 3 the lowest ranking within
its generic category.
Aaa      --  Bonds that are rated "Aaa" are judged to be of the best quality.
             They carry the smallest degree of investment risk and are generally
             referred to as "gilt edge." Interest payments are protected by a
             large or by an exceptionally stable margin and principal is secure.
             While the various protective elements are likely to change, such
             changes as can be visualized are most unlikely to impair the
             fundamentally strong position of such issues.
Aa       --  Bonds that are rated "Aa" are judged to be of high quality by all
             standards. Together with the "Aaa" group they comprise what are
             generally known as high grade bonds. They are rated lower than the
             best bonds because margins of protection may not be as large in Aaa
             securities or fluctuation of protective elements may be of greater
             amplitude or there may be other elements present which make the
             long-term risks appear somewhat larger than in Aaa securities.
A        --  Bonds that are rated "A" possess many favorable investment
             attributes and are to be considered as upper medium grade
             obligations. Factors giving security to principal and interest are
             considered adequate but elements may be present which suggest a
             susceptibility to impairment some time in the future.
Baa      --  Bonds that are rated "Baa" are considered as medium grade
             obligations, i.e., 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 bonds lack outstanding investment characteristics and in fact
             have speculative characteristics as well.
Ba       --  Bonds that are rated "Ba" are judged to have speculative elements;
             their future cannot be considered as well assured. Often the
             protection of interest and principal payments may be very moderate
             thereby not well safeguarded during both good and bad times over
             the future. Uncertainty of position characterizes bonds in this
             class.
NR       --  Indicates that the bond is not rated by Standard & Poor's or
             Moody's.

    1.  Significant Accounting Policies

    Smith Barney Massachusetts Municipals Fund ("Fund"), a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as a non-diversified, open-end management investment company.

    The significant accounting policies consistently followed by the Fund are:
(a) security transactions are accounted for on trade date; (b) securities are
valued at the mean between the quoted bid and ask prices by an independent
pricing service; (c) securities maturing within 60 days are valued at cost plus
accreted discount or minus amortized premium, which approximates value; (d)
gains or losses on the sale of securities are calculated by using the specific
identification method; (e) interest income, adjusted for amortization of premium
and accretion of original issue discount, is recorded on an accrual basis;
market discount is recognized upon the disposition of the security; (f) direct
expenses are charged to each class; management fees and general fund expenses
are allocated on the basis of relative net assets; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the Fund
intends to comply with the applicable provisions of the Internal Revenue Code of
1986, as amended, pertaining to regulated investment companies and to make
distributions of taxable income sufficient to relieve it from substantially all
Federal income and excise taxes; and (i) estimates and assumptions are required
to be made regarding assets, liabilities and changes in net assets resulting
from operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

    2.  Fund Concentration

    Since the Fund invests primarily in obligations of issuers within the
Commonwealth of Massachusetts, it is subject to possible concentration risks
associated with economic, political or legal developments or industrial or
regional matters specifically affecting Massachusetts.

    3.  Exempt-Interest Dividends and Other Distributions

    The Fund intends to satisfy conditions that will enable interest from
municipal securities, which is exempt from regular Federal income tax, to retain
such tax-exempt status when distributed to the shareholders of the Fund.

    Capital gains distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

                                                                              17

    4.  Investment Advisory Agreement, Administration Agreement and Other
        Transactions

    Smith Barney Mutual Funds Management Inc. ("SBMFM"), a subsidiary of Smith
Barney Holdings Inc. ("SBH"), acts as investment adviser to the Fund. The Fund
pays SBMFM a fee calculated at an annual rate of 0.30% of its average daily net
assets. This fee is calculated daily and paid monthly. For the six months ended
May 31, 1997, the Fund waived $18,313 of its investment advisory fees.

    SBMFM also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets up to $500
million and 0.18% of the average daily net assets in excess of $500 million.
This fee is calculated daily and paid monthly. For the six months ended May 31,
1997, the Fund waived $12,209 of its administration fees.

    Smith Barney Inc. ("SB"), another subsidiary of SBH, acts as distributor of
the Fund's shares. For the six months ended May 31, 1997, SB received sales
charges of approximately $28,000 on sales of the Fund's Class A shares.

    There is a contingent deferred sales charge ("CDSC") of 4.50% on Class B
shares, which applies if redemption occurs less than one year from initial
purchase. This CDSC declines by 0.50% the first year after purchase and
thereafter by 1.00% per year until no CDSC is incurred. Class C shares have a
1.00% CDSC, which applies if redemption occurs within the first year of
purchase. For the six months ended May 31, 1997, CDSCs paid to SB for Class B
shares were approximately $30,000.

    Pursuant to a Distribution Plan, the Fund pays a service fee with respect to
its Class A, B and C shares calculated at an annual rate of 0.15% of the average
daily net assets of each respective class. In addition, the Fund pays a
distribution fee with respect to its Class B and C shares calculated at an
annual rates of 0.50% and 0.55%, respectively, of the average daily net assets
of each class, respectively. For the six months ended May 31, 1997, total
Distribution Plan fees incurred were:

                                               Class A     Class B     Class C
===============================================================================
Distribution Plan Fees                         $22,541     $90,962       $971
===============================================================================

         All officers and one Trustee of the Fund are employees of SB.

    6.  Capital Loss Carryforwards

    At November 30, 1996, the Fund had, for Federal income tax purposes,
approximately $257,000 of capital loss carryforwards available to offset future
capital gains. To the extent that these carryforward losses are used to offset
capital gains, it is probable that the gains so offset will not be distributed.

    The amount and expiration of the carryforwards are indicated below.
Expiration occurs on November 30 of the year indicated:

                                                           2002            2003

    7.  Shares of Beneficial Interest

    As of May 31, 1997, the Fund had an unlimited number of shares of beneficial
interest authorized with a par value of $0.001 per share. The Fund has
the ability to issue multiple classes of shares. Each share of a class
represents an identical interest and has the same rights, except that each class
bears certain direct expenses, including those specifically related to the
distribution of its shares.

    At May 31, 1997, total paid-in capital amounted to the following for each 
class:

                                           Class A       Class B        Class C
