A Message From the Chairman
--------------------------------------------------------------------------------

The new millennium, so far, has been marked by higher volatility and concerns
that the bull market in stocks may be running out of steam. At SSB Citi Fund
Management LLC ("SSB Citi"), we have instituted many positive changes, with the
ultimate goal of offering our investors a well-rounded menu of stock and bond
funds that can be tailored to a wide range of investment objectives.

                                                                     [PHOTO]
                                                                     HEATH B.
                                                                     MCLENDON

                                                                     Chairman

We believe that your serious money demands professional management. Since 1937,
Smith Barney has managed the serious money of individuals, their families and
their businesses. Today, with over $395.5 billion in assets under management/1/,
we believe that SSB Citi offers choices and solutions, uniting the distinguished
history of Smith Barney with the unparalleled global reach of its parent,
Citigroup.

The Smith Barney family of funds represents a complex with a 60-year history of
investment expertise. In addition, Smith Barney is currently conducting an
extensive advertising campaign, highlighting a selection of the most popular
Smith Barney mutual funds and the investment professionals who manage them.

The Smith Barney Muni Funds -- Limited Term Portfolio ("Portfolio") seeks as
high a level of income exempt from federal income taxes/2/ as is consistent with
prudent investing. The Portfolio normally invests in securities that have
remaining maturities of 20 years or less and maintains an average effective
maturity of between 3 and 10 years. Peter Coffey and his investment team believe
intermediate-term municipal bonds currently offer attractive value for investors
seeking tax-exempt income because historically intermediate-term high quality
municipal bonds have offered higher yield potential than shorter-term bonds and
potentially less market volatility than longer-term maturity municipal bonds.

results. Investment returns and principal value will fluctuate, and redemption

Shareholder Letter
--------------------------------------------------------------------------------

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Muni
Funds-- Limited Term Portfolio ("Portfolio") for the period ended September 30,
2000. In this report we have summarized the period's prevailing economic and
market conditions and outlined our investment strategy. The information provided
in this letter represents the opinion of the manager and is not intended to be a
forecast of future events, a guarantee of future results nor investment advice.

                                                                 [PHOTO]
                                                                 PETER M.
                                                                 COFFEY

                                                                 Vice President

Further, there is no assurance that certain securities will remain in or out of
the Portfolio. Please refer to pages 10 through 20 for a list and percentage
breakdown of the Portfolio's holdings. Also, please note any discussion of the
Portfolio's holdings is as of September 30, 2000 and is subject to change. A
detailed summary of the Portfolio's performance can be found in the appropriate
sections that follow. We hope you find this report to be useful and informative.

Performance and Investment Strategy

For the six months ended September 30, 2000, the Portfolio's Class A shares,
without and with sales charges returned 2.76% and 0.71%, respectively. In
comparison, the Lehman Brothers Municipal Bond Index ("Lehman Index")/1/
returned 3.97%.

Because we think the bond markets are likely to remain volatile in the near
term, we continue to favor a gradual approach into the market. We tend to favor
longer and intermediate maturities, where we believe most of the benefits of the
steep positive slope of the municipal yield curve/2/ can be obtained.

During the reporting period, average credit quality remained relatively high in
the Portfolio. Although quality spreads during the period have widened due to
earnings pressure, especially in hospital- and healthcare-related sectors, the
difference in yield between the highest-quality issues and medium grade issues,
in our view, remained relatively modest. We think our proprietary research
enables us to invest in select medium-term credits for which perceived market
risk may be greater than our analysis otherwise indicates. Moreover, while no
guarantees can be made, we think our strategy may have the potential to increase
income over time.

     maturities of at least one year. Please note an investor cannot invest
     directly in an index.

     yield on bonds of the same credit quality but different maturities.

During the reporting period, we took advantage of rising interest rates to
generate additional yield in the Portfolio. We also looked to incorporate
additional call protection/3/ into the Portfolio by selling off some of our
higher coupon bonds with shorter calls/4/, and replacing them with bonds that
have a similar high coupon structure, but are not subject to early call.

One of the ways that we manage the Portfolio is to seek to create a built-in
income stream for the long term. To this end, we have generally focused on
investing in securities with high credit quality and good call protection, as we
believe these securities offer solid long-term values.

Moreover, we have a fairly long weighted-average life/5/ in the Portfolio
because we believe that the risk of higher inflation at the present time is
negligible. In addition, we think our greater emphasis on call protection may
provide our shareholders with consistent income if interest rates do in fact go
down.

Market Overview and Outlook

The municipal bond market continues to be dominated by supply and demand factors
such as lower new issue volume, strong retail demand and very limited
institutional demand. In addition, the U.S. Treasury market also appears to be
influenced from its own supply and demand factors and the market has become so
thin as a result of collapsing supply that a handful of seemingly minor factors
can have a dramatic impact on yields across the entire U.S. Treasury yield
curve.

In the overall bond market, yield spreads have narrowed and benchmark yield
levels have dropped by nearly a percentage point during the period in response
to evidence that underlying inflation risks have subsided and economic growth is
slowing down from the rapid 6% pace of the past year. We think there is a good
chance that the decline in yields has further to go. Yet, on the other hand, a
host of technical and other considerations may stall the market or cause yields
to rise temporarily, barring a dramatic new sign that the U.S. economic
expansion is slowing below an expected 3% to 4% annual pace.

We think conditions appear favorable for interest rates. First, on the
structural side, the massive federal surplus is fueling a collapse of U.S.
Treasury note and bond supply. On the cyclical side, potential sources of
inflation such as consumer growth being too strong and a tight labor market,
appear to be moderating. However, temporary concerns remain in the form of heavy
private sector issuance, soaring


------------
3    Call protection is the length of time during which a security cannot be
     redeemed by the issuer.

4    Callable bonds are redeemable by the issuer before the scheduled maturity
     under specific conditions and at a stated price, which usually begins at a
     premium to par and declines annually. Bonds are usually "called" when
     interest rates fall so significantly that the issuer can save money by
     floating new bonds at lower rates

5    Average life is the length of time before the principal of debt issues is
     scheduled to be repaid through amortization or sinking fund.

energy costs and the upcoming Presidential and Congressional elections. On the
energy front, we believe that recent price rises may act more like a tax
increase rather than as a spur to higher prices throughout the economy. That is,
as consumers spend more on gasoline and heating oil, they may moderate their
spending on discretionary items. Under this scenario, the results may be a
gradual slowing of growth rather than a spike in underlying inflation.

The spectacular productivity gains of this year have kept underlying inflation
at extremely comfortable levels, with the "core consumption deflator," a
favorite measure of Federal Reserve Board ("Fed") Chairman Alan Greenspan,
running at a miniscule 0.8% annual rate for the past six months. A second key
point, related to the first, is we think the likelihood of significant
additional Fed tightening appears to be minimal.

New issue supply in the municipal bond market continues to trail far behind
levels reached in 1998 and 1999. Through mid-September 2000, volume was 21%
lower than 1999 levels, while full-year 1999 issuance had already declined 21%
from the 1998 peak. The main reason for the decline is the lack of refunding
volume. With interest rates still higher than they were during 1998 and the
first half of 1999, issuers have had little incentive to refund previous issues.

Individual investor demand for municipals has remained extremely strong, despite
the recent easing of yields from early 2000 levels. Given the small size of the
municipal bond market relative to the stock market, even a modest shift of
assets out of stocks and into municipals can create an enormous amount of new
demand for municipal bonds. In short, we think municipal bonds appear to be
attractively priced relative to underlying inflation rates in an environment of
very light supply and muted or near-dormant institutional demand.

Thank you for investing in the Smith Barney Muni Funds - Limited Term Portfolio.
We look forward to helping you pursue your financial goals in the future.

Sincerely,

/s/ Peter M. Coffey

+    Hypothetical illustration of $10,000 invested in Class A shares on
     September 30, 1990, assuming deduction of the maximum 2.00% sales charge at
     the time of investment and reinvestment of dividends (after deduction of
     applicable sales charge through November 6, 1994, afterwards at net asset
     value) and capital gains, if any, at net asset value through September 30,
     2000. The Lehman Brothers Municipal 10-Year Bond Index (consisting of
     maturities of 10 years) is a sub-index of the Lehman Brothers Municipal
     Bond Index, a broad-based, total return index comprised of investment
     grade, fixed rate municipal bonds selected from issues larger than $50
     million issued since January 1984. Each index is unmanaged and is not
     subject to the same management and trading expenses of a mutual fund. The
     performance of the Portfolio'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 (unaudited)
--------------------------------------------------------------------------------

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service  ("Standard & Poor's") -- Ratings from "AA" to
"CCC" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

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 differ 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 they are 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 and  -- Bonds rated "BB" and "CCC" are regarded, on balance, as predominantly
CCC        speculative with respect to the issuer's capacity to pay interest and
           repay principal in accordance with the terms of the obligation. BB
           indicates the lowest degree of speculation and C the highest degree
           of speculation. While such bonds will likely have some quality and
           protective characteristics, these are outweighed by large
           uncertainties or major risk exposures to adverse conditions.

Moody's Investors Service Inc. ("Moody's") -- Numerical modifiers 1, 2 and 3 may
be applied to each generic rating from "Aa" to "Caa", where 1 is the highest and
3 the lowest ranking within its generic category.

Aaa     -- Bonds 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 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 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 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 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, and therefore
           not well safeguarded during both good and bad times over the future.
           Uncertainty of position characterizes bonds in this class.
Caa     -- Bonds that are rated "Caa" are of poor standing. Such issues may be
           in default or there may be present elements of danger with respect to
           principal or interest.

Bond Ratings (unaudited) (continued)
--------------------------------------------------------------------------------

Fitch IBCA, Inc. ("Fitch") -- Ratings may be modified by the addition of a plus
(+) or minus (-) sign to show relative standings within the major rating
categories.

A       -- Bonds rated "A" are considered to be investment grade and of high
           credit quality. The obligor's ability to pay interest and/or
           dividends and repay principal is considered to be strong, but may be
           more vulnerable to adverse changes in economic conditions and
           circumstances than securities with higher ratings.
BBB     -- Bonds rated "BBB" are considered to be investment grade and of
           satisfactory credit quality. The obligor's ability to pay interest or
           dividends and repay principal is considered to be adequate. Adverse
           changes in economic conditions and circumstances, however, are more
           likely to have adverse impact on these securities and, therefore,
           impair timely payment. The likelihood that the ratings of these bonds
           will fall below investment grade is higher than for securities with
           higher ratings.
NR      -- Indicates that the bond is not rated by Standard & Poor's, Moody's
           or Fitch.

--------------------------------------------------------------------------------
Short-Term Security Ratings (unaudited)
--------------------------------------------------------------------------------

SP-1    -- Standard & Poor's highest rating indicating very strong or strong
           capacity to pay principal and interest; those issues determined to
           possess overwhelming safety characteristics are denoted with a plus
           (+) sign.
A-1     -- Standard & Poor's highest commercial paper and variable rate demand
           obligation (VRDO) rating indicating that the degree of safety
           regarding timely payment iseither overwhelming or very strong; those
           issues determined to possess overwhelming safety characteristics are
           denoted with a plus (+) sign.
VMIG 1  -- Moody's highest rating for issues having a demand feature -- VRDO.
MIG 1   -- Moody's highest rating for short-term municipal obligations.
P-1     -- Moody's highest rating for commercial paper and for VRDO prior to the

 1.   Significant Accounting Policies

The Limited Term Portfolio ("Portfolio") is a separate, diversified investment
portfolio of the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company and consists of this
Portfolio and eight other separate investment portfolios: Florida, Georgia, New
York, Pennsylvania, National, California Money Market, New York Money Market and
Massachusetts Money Market Portfolios. The financial statements and financial
highlights for the other portfolios are presented in separate shareholder
reports.

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 provided by an independent
pricing service that are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable
securities and various relationships between securities; (c) securities for
which market quotations are not available will be valued in good faith at fair
value by or under the direction of the Board of Trustees; (d) securities for
which market quotations are not available will be valued in good faith at fair
market value by or under the direction of the Board of Trustees; (e) securities
maturing within 60 days are valued at cost plus accreted discount or minus
amortized premium, which approximates value; (f) gains or losses on the sale of
securities are calculated by using the specific identification method; (g)
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; (h) dividends and distributions to
shareholders are recorded on the ex-dividend date; (i) direct expenses are
charged to each Portfolio and each class; management fees and general fund
expenses are allocated on the basis of relative net assets by class; (j) each
Portfolio 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; (k) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles; and
(l) 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. Exempt-Interest Dividends and Other Distributions

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

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

3. Management Agreement and Transactions with Affiliated Persons

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Fund. The Portfolio pays SSBC a
management fee calculated at an annual rate of 0.50% of its average daily net
assets. This fee is calculated daily and paid monthly.

Citi Fiduciary Trust Company ("CFTC"), another subsidiary of Citigroup, acts as
the Fund's transfer agent and PFPC Global Fund Services ("PFPC") acts as the
Fund's sub-transfer agent. CFTC receives account fees and asset-based fees that
vary according to the size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder accounts
and is paid by CFTC. During the six months ended September 30, 2000, the
Portfolio paid transfer agent fees of $25,702 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Fund's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Fund's portfolio agency
transactions. Certain other broker-dealers continue to sell Portfolio shares to
the public as members of the selling group.

There are maximum initial sales charges of 2.00% and 1.00% for Class A and L
shares, respectively. There is a contingent deferred sales charge ("CDSC") of
1.00% on Class A shares, which applies if redemption occurs within one year from
purchase. This CDSC only applies to those purchases of Class A shares, which,
when combined with current holdings of Class A shares, equal or exceed $500,000
in the aggregate. These purchases do not incur an initial sales charge. Class L
shares also have a 1.00% CDSC, which applies if redemption occurs within the
first year of purchase.

       1 Smith Barney Muni Funds | 2000 Semi-Annual Report to Shareholders
<PAGE>

Dear Shareholder,

We are pleased to provide the semi-annual report for the Smith Barney Muni Funds
-- National Portfolio ("Portfolio") for the period ended September 30, 2000. In
this report we have summarized the period's prevailing economic and market
conditions and outlined our investment strategy. The information provided in
this letter represents the opinion of the manager and is not intended to be a
forecast of future events, a guarantee of future results nor investment advice.

Further, there is no assurance that certain securities will remain in or out of
the Portfolio. Please refer to pages 7 through 15 for a list and percentage
breakdown of the Portfolio's holdings. Also, please note any discussion of the
Portfolio's holdings is as of September 30, 2000 and is subject to change. A
detailed summary of the Portfolio's performance can be found in the appropriate
sections that follow. We hope you find this report to be useful and informative.

Performance Update

For the six months ended September 30, 2000, the Portfolio's Class A shares,
without and with sales charges, returned 3.67% and a negative 0.49%,
respectively. In comparison, the Lehman Brothers Municipal Bond Index ("Lehman
Index")/1/ returned 3.97%.

Investment Strategy

Because we think the bond markets are likely to remain volatile in the near
term, we continue to favor a gradual approach into the market. We tend to favor
longer and intermediate maturities, where most of the benefits of the steep
positive slope of the municipal yield curve/2/ can be obtained.

During the period, average credit quality remained relatively high in the
Portfolio. Although quality spreads during the period have widened due to
earnings pressure, especially in hospital -- and health care-related sectors,
the difference in yield between the highest-quality issues and medium grade
issues, in our view, remained relatively modest. We think our proprietary
research enables us to invest in select medium-term credits for which perceived
market risk may be greater than our analysis otherwise indicates. Moreover,
while no guarantees can be made, we think our strategy may have the potential to
increase income over time.

During the period, we took advantage of rising interest rates to generate
additional yield in the Portfolio. We also looked to incorporate additional call
protection/3/ into the Portfolio by selling off some of our higher coupon bonds
with shorter calls,/4/ and replacing them with bonds that have a similar high
coupon structure, but are not subject to early call.

One of the ways that we manage the Portfolio is to seek to create a built-in
income stream for the long-term. To this end, we have generally focused on
investing in securities with high credit quality and good call protection, as we
believe these securities offer solid long-term values. Moreover, we have a
fairly long weighted-average life/5/ in the Portfolio because we believe that
the risk of higher inflation at the present time is negligible. In addition, we
think our greater emphasis on call protection may provide our shareholders with
consistent income if interest rates do in fact go down.

----------
/1/  The Lehman Index is a broad measure of the municipal bond market with
     maturities of at least one year. Please note an investor cannot invest
     directly in an index.
/2/  The yield curve is the graphical depiction of the relationship between the
     yield on bonds of the same credit quality but different maturities.
/3/  Call protection is the length of time during which a security cannot be
     redeemed by the issuer.
/4/  Callable bonds are redeemable by the issuer before the scheduled maturity
     under specific conditions and at a stated price, which usually begins at a
     premium to par and declines annually. Bonds are usually "called" when
     interest rates fall so significantly that the issuer can save money by
     floating new bonds at lower rates.
/5/  Average life is the length of time before the principal of debt issues is
     scheduled to be repaid through amortization or sinking fund.

       2 Smith Barney Muni Funds | 2000 Semi-Annual Report to Shareholders

Market Overview and Outlook

The municipal bond market continues to be dominated by supply and demand factors
such as lower new issue volume, strong retail demand and very limited
institutional demand. In addition, the U.S. Treasury market also appears to be
influenced from its own supply and demand factors and the market has gotten so
thin as a result of collapsing supply that a handful of seemingly minor factors
can have a dramatic impact on yields across the entire U.S. Treasury yield
curve.

In the overall bond market, yield spreads have narrowed and benchmark yield
levels have dropped by nearly a percentage point during the period in response
to evidence that underlying inflation risks have subsided and economic growth is
slowing down from the rapid 6% pace of the past year. We think there is a good
chance that the decline in yields has further to go. Yet, on the other hand,
host of technical and other considerations may stall the market or cause yields
to rise temporarily, barring a dramatic new sign that the U.S. economic
expansion is slowing below an expected 3% to 4% annual pace.

We think conditions appear favorable for interest rates. First, on the
structural side, the massive federal surplus is fueling a collapse of U.S.
Treasury note and bond supply. On the cyclical side, potential sources of
inflation such as too strong consumer growth and a tight labor market, appear to
be moderating. However, temporary concerns remain in the form of heavy private
sector issuance, soaring energy costs and the upcoming Presidential and
Congressional elections.

On the energy front, we believe that the recent price rises may act more like a
tax increase rather than as a spur to higher prices throughout the economy. That
is, as consumers spend more on gasoline and heating oil, they may moderate their
spending on discretionary items. Under this scenario, the results may be a
gradual slowing of growth rather than a spike in underlying inflation.

The spectacular productivity gains of this year have kept underlying inflation
at extremely comfortable levels, with the "core consumption deflator," a
favorite measure of Federal Reserve Board ("Fed") Chairman Alan Greenspan,
running at a minis-cule 0.8% annual rate for the past six months. A second key
point, related to the first, is we think the likelihood of significant
additional Fed tightening appears to be minimal.

New issue supply in the municipal bond market continues to trail far behind
levels reached in 1998 and 1999. Through mid-September 2000, volume was 21%
lower than 1999 levels, while full-year 1999 issuance had already declined 21%
from the 1998 peak. The main reason for the decline is the lack of refunding
volume. With interest rates still higher than they were during 1998 and the
first half of 1999, issuers have had little incentive to refund previous issues.

Individual investor demand for municipals has remained extremely strong, despite
the recent easing of yields from early 2000 levels. Given the small size of the
municipal bond market relative to the stock market, even a modest shift of
assets out of stocks into municipals can create an enormous amount of new demand
for municipal bonds. In short, we think municipal bonds appear to be
attractively priced relative to underlying inflation rates in an environment of
very light supply and muted or near-dormant institutional demand.

Thank you for investing in the Smith Barney Muni Funds -- National Portfolio. We
look forward to helping you pursue your financial goals in the future.

(1)  Assumes reinvestment of all dividends and capital gain distributions at net
     asset value and does not reflect the deduction of the applicable sales
     charges with respect to Class A and L shares or the applicable contingent
     deferred sales charges ("CDSC") with respect to Class B and L shares.
(2)  Assumes reinvestment of all dividends and capital gain distributions at net
     asset value. In addition, Class A and L shares reflect the deduction of the
     maximum initial sales charge of 4.00% and 1.00%, respectively. Class B
     shares reflect the deduction of a 4.50% CDSC, which applies if shares are
     redeemed within one year from 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 L shares also reflect the deduction of a 1.00% CDSC, which
     applies if shares are redeemed within the first year of purchase.
*    Inception dates for Class A, B and L shares are August 20, 1986, November
     7, 1994 and January 5, 1993, respectively.
+    Total return is not annualized, as it may not be representative of the

+    Hypothetical illustration of $10,000 invested in Class A shares on
     September 30, 1990, assuming deduction of the maximum 4.00% sales charge at
     the time of investment and reinvestment of dividends (after deduction of
     applicable sales charges through November 6, 1994, and thereafter at net
     asset value) and capital gains (at net asset value) through September 30,
     2000. The Lehman Brothers Municipal Bond Index is a broad-based, total
     return index comprised of investment grade, fixed-rate municipal bonds
     selected from issues larger than $50 million issued since January 1984.
     This index is unmanaged and is not subject to the same management and
     trading expenses as a mutual fund. An investor may not invest directly in
     an index. The performance of the Portfolio'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 (unaudited)
--------------------------------------------------------------------------------
The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("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.

AAA                     -- Bonds rated "AAA" have the highest rating assigned
                           by Standard & Poor's to a debt obligation. 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 differ from the
                           highest rated issues only in a small degree.
A                       -- Bonds rated "A" have a strong capacity to pay
                           interest and repay principal although they are some-
                           what more susceptible to the adverse effects of
                           changes in circumstances and economic conditions than
                           debt 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 for bonds in higher
                           rated categories.

BB and B                -- Bonds rated "BB" and "B" are regarded, on balance, as
                           predominantly speculative with respect to the
                           issuer's capacity to pay interest and repay principal
                           in accordance with the terms of the obligation. "BB"
                           indicates the lowest degree of speculation and "B"
                           the highest degree of speculation. While such bonds
                           will likely have some quality and protective
                           characteristics, these are outweighed by large
                           uncertainties or major risk exposures to adverse
                           conditions.

Moody's Investors Service, Inc. ("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 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 posi-
                           tion of such issues.
Aa                      -- Bonds 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 ele-
                           ments 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 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 rated "Baa" are considered to be medium grade
                           obligations, i.e., they are neither highly pro-
                           tected 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 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 and thereby
                           not well safeguarded during both good and bad times
                           over the future. Uncertainty of position charac-
                           terizes bonds in this class.

  Bond Ratings (unaudited) (continued)
--------------------------------------------------------------------------------

Fitch IBCA, Inc. ("Fitch") -- Rating may be modified by the addition of a plus
(+) or minus (-) sign to show relative standings with the major ratings
categories.

A                       --     Bonds rated "A" are considered to be investment
                               grade and of high credit quality. The obligor's
                               ability to pay interest and/or dividends and
                               repay principal is considered to be strong, but
                               may be more vulnerable to adverse changes in
                               economic conditions and circumstances than debt
                               securities with higher ratings.

NR                      --     Indicates that the bond is not rated by Standard
                               & Poor's, Moody's or Fitch.

--------------------------------------------------------------------------------
Short-Term Ratings (unaudited)
--------------------------------------------------------------------------------

SP-1             --     Standard & Poor's highest rating indicating very strong
                        or strong capacity to pay principal and interest; those
                        issues determined to possess overwhelming safety
                        characteristics are denoted with a plus (+) sign.

A-1              --     Standard & Poor's highest commercial paper and variable-
                        rate demand obligation (VRDO) rating indicating that the
                        degree of safety regarding timely payment is either
                        overwhelming or very strong; those issues determined to
                        possess overwhelming safety characteristics are denoted
                        with a plus (+) sign.

VMIG 1           --     Moody's highest rating for issues having a demand
                        feature -- VRDO.

P-1              --     Moody's highest rating for commercial paper and for
                        VRDO prior to the advent of the VMIG 1 rating.

  Notes to Financial Statements (unaudited)
--------------------------------------------------------------------------------

1. Significant Accounting Policies

The National Portfolio ("Portfolio") is a separate diversified investment
portfolio of the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company and consists of this
Portfolio and eight other separate investment portfolios: Florida, Georgia,
Limited Term, New York, Pennsylvania, California Money Market, Massachusetts
Money Market and New York Money Market Portfolios. The financial statements and
financial highlights for the other portfolios are presented in separate
shareholder reports.

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 bid and ask prices provided by an independent pricing
service which are based on transactions in municipal obligations, quotations
from municipal bond dealers, market transactions in comparable securities and
various relationships between securities; (c) securities for which market
quotations are not available will be valued in good faith at fair value by or
under the direction of the Board of Trustees; (d) securities maturing within 60
days are valued at cost plus accreted discount or minus amortized premium, if
any, which approximates value; (e) gains or losses on the sale of securities are
calculated by using the specific identification method; (f) 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; (g) dividends and distributions to shareholders are
recorded on the ex-dividend date; (h) direct expenses are charged to each
Portfolio and each class; management fees and general fund expenses are
allocated on the basis of relative net assets by class; (i) the character of
income and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles; (j)
the Portfolio 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 (k) 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. Exempt-Interest Dividends and Other Distributions

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

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

3. Management Agreement and Other Transactions

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Portfolio. The Portfolio pays
SSBC a management fee calculated at the annual rate of 0.45% of the average
daily net assets. This fee is calculated daily and paid monthly.

Citi Fiduciary Trust Company ("CFTC"), another subsidiary of Citigroup, acts as
the Portfolio's transfer agent and PFPC Global Fund Services ("PFPC") acts as
the Portfolio's sub-transfer agent. CFTC receives account fees and asset-based
fees that vary according to the account size and type of account. PFPC is
responsible for shareholder recordkeeping and financial processing for all
shareholder accounts and is paid by CFTC. For the six months ended September 30,
2000, the Portfolio paid transfer agent fees of $45,475 to CFTC.

--------------------------------------------------------------------------------

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, acts as the Portfolio's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Portfolio's agency
transactions. Certain other broker-dealers, continue to sell Portfolio shares to
the public as members of the selling group.

There are maximum initial sales charges of 4.00% and 1.00% for Class A and L
shares, respectively. There is a contingent deferred sales charge ("CDSC") of
4.50% on Class B shares, which applies if redemption occurs within one year from
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 L shares also have
a 1.00% CDSC, which applies if redemption occurs within the first year of
purchase. In certain cases, Class A shares have a 1.00% CDSC, which applies if
redemption occurs within the first year of purchase. This CDSC only applies to
those purchases of Class A shares, which when combined with current holdings of
Class A shares, equal or exceed $500,000 in the aggregate. These purchases do
not incur an initial sales charge.

For the six months ended September 30, 2000, SSB and CFBDS received sales
charges of $4,302,000 and $1,250,000 on sales of the Portfolio's Class A and L
shares, respectively. In addition, CDSCs paid to SSB were approximately:

                            Class A       Class B         Class L
==================================================================
CDSCs                       $4,000        $226,000        $26,000
==================================================================

Pursuant to a Distribution Plan, the Portfolio pays a service fee with respect
to Class A, B and L shares calculated at the annual rate of 0.15% of the average
daily net assets of each respective class. In addition, the Portfolio pays a
distribution fee with respect to Class B and L shares calculated at the annual
rates of 0.50% and 0.55% of the average daily net assets of each class,
respectively. For the six months ended September 30, 2000, total Distribution
Plan fees incurred were:

                            Class A       Class B         Class L
==================================================================
Distribution Plan Fees     $273,874      $135,468         $66,007
==================================================================

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

4. Investments

During the six months ended September 30, 2000, the aggregate cost of purchases
and proceeds from sales of investments (including maturities, but excluding
short-term securities) were as follows:

==================================================================
Purchases                                             $137,258,606
------------------------------------------------------------------
Sales                                                  139,505,545
==================================================================

At September 30, 2000, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

==================================================================
Gross unrealized appreciation                          $15,914,439
Gross unrealized depreciation                           (6,946,330)
------------------------------------------------------------------
Net unrealized appreciation                             $8,968,109
==================================================================

5. Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contract. During the period the
futures contract is open, changes in the value of the contract are recognized as
unre-

--------------------------------------------------------------------------------
Notes to Financial Statements (unaudited) (continued)
--------------------------------------------------------------------------------

alized gains or losses by "marking-to-market" on a daily basis to reflect the
market value of the contract at the end of each day's trading. Variation margin
payments are made or received and recognized as assets due from or liabilities
due to broker, depending upon whether unrealized gains or losses are incurred.
When the contract is closed, the Portfolio records a realized gain or loss equal
to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract. The Portfolio enters
into such contracts to hedge a portion of its portfolio. The Portfolio bears the
market risk that arises from changes in the value of the financial instruments
and securities indices (futures contracts).

At September 30, 2000, the Portfolio had no open futures contracts.

6. Capital Loss Carryforward

At March 31, 2000, the Portfolio had, for Federal income tax purposes,
approximately $4,176,000, respectively, of unused capital loss carryforwards
available to offset future capital gains expiring March 31, 2008. 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.

7. Shares of Beneficial Interest

At September 30, 2000, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolio has the
ability to issue multiple classes of shares. Each share of a class represents an
identical interest in the Portfolio and has the same rights, except that each
class bears certain expenses specifically related to the distribution of its
shares.

At September 30, 2000, total paid-in capital amounted to the following for each
class:

Municipal Market and Economic Overview

Municipal bonds have been a very simple story throughout 2000. They started at
relatively inexpensive valuations and then rallied. In our opinion, stable
interest rates and an economy with few excesses are painting a bullish picture
for bonds in general, while declining new issue supply may be further bolstering
the municipal bond market. In addition, the national economy has produced large
cash surpluses in many states and municipalities, causing general improvement in
the credit quality of municipal securities and credit worthiness of their
securities.

With most states and local governments enjoying balanced budgets or surpluses,
we think borrowing is likely to total no more than $150 billion to $180 billion
over the next two years. As new issuance remains low, we also believe municipal
securities may start to trade away from taxable bonds. Many municipal bonds are
now yielding almost 95% of comparable-maturity U.S. Treasuries, but we expect
that percentage to return to historical average spreads, in the range of 80% to
85%.

From our point of view, the past few months have been a positive period for the
municipal market. As the stock market endured its correction in March and April
2000, municipal bonds forged ahead slowly but relentlessly. In our view, the
municipal markets are in a state of flux that may lead to greater opportunities.
The federal government conducted a buy back of long-term government bonds early
in 2000, which drove down yields.

Under Federal Reserve Board ("Fed") Chairman Alan Greenspan, the Fed has raised
interest rates incrementally several times in order to cool a robust U.S.
economy. We do not see the Fed raising interest rates again for the foreseeable
future, at least until after Election Day. In an attempt to be apolitical, the
Fed's Board of Governors tends to shy away from such dramatic moves in an
election year, to avoid charges of influencing an election.

We are carefully monitoring a number of factors in the municipal market. We are
looking to see who wins not just the Presidential, but also Congressional
elections, since the House of Representatives is where all spending bills
originate. We also closely watch the price of oil, but disagree with those who
see it as a harbinger of doom for the economy.

The market had little reaction to the Fed's decision to keep interest rates
steady or to the Fed's view that risk in the economy is weighted toward
inflation. The bond market is still pricing in another possible Fed tightening
by the end of the year. We expect Fed policy to remain steady throughout 2000,
and we would not be surprised if the Fed were to shift to a more neutral
position before the end of the year. A critical point, which is often overlooked
by many investors, is
--------------------------------------------------------------------------------

<PAGE>

that Fed monetary policy adjustments take time to be absorbed into the general
economy. The Fed has tightened 175 basis points/3/ from the bottom, and the
recent rallies we have seen are a result of changes enacted six- to twelve-
months ago.

Municipal bond prices, in general, have been very firm lately: since late May, a
triple 'A' 10 year municipal index has experienced price improvement (a yield
decline) of 50 basis points or more. Demand in the municipal market has been
steady to increasing as recent volatility in the stock market will undoubtedly
lead some investors to rethink their portfolio mix, and to establish or augment
bond positions in their portfolios.

New York Economic Highlights/4/

New York State is the 10th largest economy in the world and its Gross State
Product of $593 billion accounts for roughly eight percent of U.S. Gross
Domestic Product ("GDP")./5/ New York has a broad and diverse economy with a
concentration of employment in financial services, information and media
services, fashion, transportation equipment and distribution industries.

Over the past few years, the Empire State has moved aggressively to create a
top-notch business climate, and its efforts have clearly had a positive impact
on the state's economy. In our opinion, the turnaround may be a direct result of
changes in the state's economic policy over the last three years. Lower taxes,
the elimination of red tape and other bureaucratic obstacles to growth, prudent
fiscal practices and a business friendly pro-jobs climate have improved New
York's economic competitiveness.

In our opinion, New York State's financial future remains bright. While the
Empire State's debt structure is complex, the burden on resources remains
moderate. Going forward, we are optimistic about the attractiveness of select
New York municipal securities.

New York Money Market Portfolio's Performance Update
and Investment Strategy

The New York Money Market Portfolio seeks to provide investors with income
exempt from federal income tax and New York State and City personal income
taxes/6/ by investing in a portfolio of high quality, short-term New York
municipal obligations selected for liquidity and stability of principal.

-----------------
3    A basis point is 0.01% or one one-hundredth of a percent.
4    Sources: Fitch IBCA, Inc., Duff & Phelps.
5    GDP is the market value of the goods and services produced by labor and
     property in the U.S. GDP is comprised of consumer and government purchases,
     private domestic investments and net exports of goods and services.

<PAGE>

The Portfolio invests only in short-term securities that we believe carry
minimal credit risk. All of the Portfolio's holdings are rated within the top
two short-term credit rating categories or are of comparable quality.

Please note that your investment in the Portfolio is neither insured, nor
guaranteed, by the Federal Deposit Insurance Corporation or any other government
agency. Although the Portfolio seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Portfolio.

As of September 30, 2000, the Portfolio's 7-day current yield was 4.02%. The
Portfolio's 7-day effective yield/7/ -- which reflects compounding -- was 4.10%.

During the period, we increased the Portfolio's average maturity/8/ target to a
65- to 70- day range. We have extended the Portfolio's average maturity by
buying what we deem to be high quality liquid municipal notes.

The Portfolio's increased average maturity reflects:

 .    A slowdown in economic activity over the near-term; and

 .    Less supply of high quality short-term municipal paper.


The record expansion of the U.S. economy has produced budget surpluses for many
state and local governments, which in turn has decreased the need for short-term
cash flow financing.

Municipal Money Market Overview

On May 16, 2000, the Fed increased the federal funds rate ("fed funds rate")/9/
by 50 basis points, however, the supply and demand imbalance in the short-term
municipal market put pressures on both the municipal note and the Variable Rate
Demand Obligation ("VRDO")/10/ markets and at times, defied rising rates.

-----------------
7    The seven-day effective yield is calculated similarly to the seven-day
     yield but, when annualized, the income earned by an investment in the
     Portfolio or the class is assumed to be reinvested. The effective yield
     will be slightly higher than the yield because of the compounding effect of
     the assumed reinvestment.
8    Average maturity refers to the average date on which the principal is
     required to be paid on the bond.
9    The fed funds rate is the interest rate that banks with excess reserves at
     a Federal Reserve district bank charge other banks that need overnight
     loans. The fed funds rate often points to the direction of U.S. interest
     rates.
10   VRDOs are demand instruments that usually have an indicated maturity of
     more than one year, but contain a demand feature that enables the holder to
     redeem the investment on no more than 30 days notice. These instruments
     provide for automatic adjustment of new rates on set dates and are
     generally supported by letters of credit issued by domestic or foreign
     banks.
--------------------------------------------------------------------------------
6                                        2000 Semi-Annual Report to Shareholders
<PAGE>

During the period, the Bond Buyer One Year Municipal Note Index11 increased by
approximately 60 basis points to a high of 4.64% in early May of 2000. The
market then looked to June, which is the fiscal year end for most state and
local governments, however less issuance was announced for fiscal year 2001 and
as a result the Bond Buyer One Year Municipal Note Index reacted by falling to a
4.20% by late September.

In the VRDO market, which represents the shorter end of the municipal money
market yield curve, supply and demand imbalances have led to increased
volatility during periods of cyclical cash flows. Over the normal course of the
year, tax-exempt money funds tend to experience large cyclical cash flows. For
example, during the month of April, yields for VRDOs in New York surged as
tax-exempt money funds experienced large redemptions relating to income tax
payments. During the month of July, when tax-exempt money funds experience large
inflows from bond coupon collections and bond calls, yields quickly retreated to
levels more expensive than their taxable equivalents.

Going forward, we believe there may be a greater amount of supply of short-term
municipal securities in New York that become available from decade old municipal
bond issuance. The older issuances are now eligible either by pre-refunding12 or
by maturing in 13 months or less.

In closing, thank you for investing in the Smith Barney Muni Funds -- New York
Money Market Portfolio and New York Portfolio. We look forward to continuing to
help you pursue your financial goals in the future.



Sincerely,

11   The Bond Buyer One Year Municipal Note Index is comprised of ten large
     municipal note issues rated MIG 1 by Moody's Investors Service, Inc. or SP
     +/SP-1 by Standard and Poor's Ratings Service, representing a cross section
     of the municipal note market. Please note an investor cannot invest
     directly in an index.
12   Pre-refunding occurs when an issuer refinances debt through the issuance of
     a new bond deal. The proceeds from the new bond sale are placed in an
     escrow account and are used to retire the debt to the earliest call date.

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect the deduction of the
     applicable sales charges with respect to Class A and L shares or the
     applicable contingent deferred sales charges ("CDSC") with respect to Class
     B and L shares.

(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A and L shares reflect the
     deduction of the maximum initial sales charge of 4.00% and 1.00%,
     respectively; Class B shares reflect the deduction of a 4.50% CDSC, which
     applies if shares are redeemed within one year from 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 L shares also reflect the deduction
     of a 1.00% CDSC, which applies if shares are redeemed within the first year
     of purchase.

*    Inception dates for Class A, B and L shares are January 16, 1987, November
     11, 1994 and January 8, 1993, respectively.

+    Hypothetical illustration of $10,000 invested in Class A shares on
     September 30, 1990, assuming deduction of the maximum 4.00% sales charge at
     the time of investment and reinvestment of dividends (after deduction of
     applicable sales charges through November 6, 1994 and thereafter at net
     asset value) and capital gains, if any, at net asset value through
     September 30, 2000. The Lehman Brothers Municipal Bond Index is a
     broad-based, total return index comprised of investment grade, fixed rate
     municipal bonds selected from issues larger than $50 million issued since
     January 1991. This Index is unmanaged and is not subject to the same
     management and trading expenses of a mutual fund. The performance of the
     Portfolio'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 (unaudited)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("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.

AAA  --   Bonds rated "AAA" have the highest rating assigned by Standard &
          Poor's to a debt obligation. 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 differ 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 they are somewhat more susceptible to the adverse
          effects of changes in circumstances and economic conditions than debt
          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
and B --  Bonds rated "BB" and "B" are regarded, on balance, as predominantly
          speculative with respect to the issuer's capacity to pay interest and
          repay principal in accordance with the terms of the obligation. "BB"
          indicates the lowest degree of speculation and "B" the highest degree
          of speculation. While such bonds will likely have some quality and
          protective characteristics, these are outweighed by large
          uncertainties or major risk exposures to adverse conditions.


Moody's Investors Service, Inc. ("Moody's") -- Numerical modifiers 1, 2 and 3
may be applied to each generic rating from "Aa" to "B", where 1 is the highest
and 3 the lowest ranking within its generic category.

Aaa  --   Bonds 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 these bonds.

Aa   --   Bonds 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 as 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 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 rated "Baa" are considered as medium grade obligations, i.e.,
          they are neither highly protected nor poorly secured. Interest payment
          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 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, and thereby not well
          safeguarded during both good and bad times over the future.
          Uncertainty of position characterizes bonds in this class.

B    --   Bonds rated "B" generally lack characteristics of the desirable
          investments. Assurance of interest and principal payments or
          maintenance of other terms of the contract over any long period of
          time may be small.

NR   --   Indicates the bond is not rated by Standard & Poor's or Moody's.

Short-Term Security Ratings (unaudited)
--------------------------------------------------------------------------------
SP-1 --   Standard & Poor's highest rating indicating very strong or strong
          capacity to pay principal and interest; those issues determined to
          possess overwhelming safety characteristics are denoted with a plus
          (+) sign.

A-1  --   Standard & Poor's highest commercial paper and variable rate demand
          obligation (VRDO) rating indicating that the degree of safety
          regarding timely payment is either overwhelming or very strong; those
          issues determined to possess overwhelming safety characteristics are
          denoted with a plus (+) sign.

P-1  --   Moody's highest rating for commercial paper and for VRDO prior to the
          advent of the VMIG 1 rating.

VMIG 1   --   Moody's highest rating for issues having a demand feature -- VRDO.
MIG 1    --   Moody's highest rating for short-term municipal obligations.
MIG 2    --   Moody's second highest rating for short-term municipal
              obligations.

1.  Significant Accounting Policies

The New York Money Market and New York Portfolios ("Portfolios") are separate
investment portfolios of the Smith Barney Muni Funds ("Fund"). The Fund, a
Massachusetts business trust, is registered under the Investment Company Act of
1940, as amended, as an open-end management investment company and consists of
these Portfolios and seven other separate investment portfolios: Florida,
Georgia, Pennsylvania, Limited Term, National, Massachusetts Money Market and
California Money Market Portfolios. The New York Portfolio is an open-end
non-diversified investment portfolio of this Fund. The financial statements and
financial highlights for the other portfolios are presented in separate
shareholder reports.

The significant accounting policies consistently followed by the Fund are:
(a) security transactions are accounted for on trade date; (b) with respect to
the New York Portfolio, securities are valued at the mean between the quoted bid
and ask prices provided by an independent pricing service that are based on
transactions in municipal obligations, quotations from municipal bond dealers,
market transactions in comparable securities and various relationships between
securities; the New York Money Market Portfolio uses the amortized cost method
for valuing investments; accordingly, the cost of securities plus accreted
discount, or minus amortized premium, approximates value; (c) securities
maturing within 60 days are valued at cost plus accreted discount or minus
amortized premium, which approximates value; (d) securities for which market
quotations are not available will be valued in good faith at fair value by or
under the directions of the Board of Trustees; (e) gains or losses on the sale
of securities are calculated by using the specific identification method; (f)
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; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) direct expenses are
charged to each portfolio and each class; management fees and general fund
expenses are allocated on the basis of relative net assets; (i) the Portfolios
intend 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 them from substantially
all Federal income and excise taxes; (j) the character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles. At March 31, 2000,
reclassifications were made to the New York Money Market Portfolio's capital
accounts to reflect permanent book/tax differences and income and gains
available for distributions under income tax regulations. Accordingly, for the
New York Money Market Portfolio a portion of accumulated net realized loss
amounting to $95,660 was reclassified to paid-in capital. Net investment income,

--------------------------------------------------------------------------------
Notes to Financial Statements (unaudited) (continued)
--------------------------------------------------------------------------------
net realized gains and net assets were not affected by this change; and (k)
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.   Portfolio Concentration

Since the Portfolios invest primarily in obligations of issuers within New York,
it is subject to possible concentration risks associated with economic,
political, or legal developments or industrial or regional matters specifically
affecting New York.

3.   Exempt-Interest Dividends and Other Distributions

The New York Money Market Portfolio declares and records a dividend of
substantially all of its net investment income on each business day. Such
dividends are paid or reinvested monthly in Portfolio shares on the payable
date. Furthermore, each Portfolio intends to satisfy conditions that will enable
interest from municipal securities, which is exempt from Federal income tax and
from designated state income taxes, to retain such tax-exempt status when
distributed to the shareholders of the Portfolio.

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

4.   Management Agreement and Other Transactions

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Portfolios. The New York Money
Market Portfolio pays SSBC a management fee calculated at an annual rate of
0.50% on the first $2.5 billion of average daily net assets; 0.475% on the next
$2.5 billion and 0.45% on the average daily net assets in excess of $5 billion.
The New York Portfolio pays SSBC a management fee calculated at the annual rate
of 0.50% of its average daily net assets. These fees are calculated daily and
paid monthly.

Citi Fiduciary Trust Company ("CFTC"), another subsidiary of Citigroup, acts as
the Portfolios' transfer agent and PFPC Global Fund Services ("PFPC") acts as
the Portfolios' sub-transfer agent. CFTC receives account fees and asset-based
fees that vary according to the size and type of account. PFPC is responsible
for shareholder recordkeeping and financial processing for all shareholder
accounts and is paid by CFTC. For the six months ended September 30, 2000, the
Portfolios paid transfer agent fees of $290,122 to CFTC.

--------------------------------------------------------------------------------

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subisdiary of
SSBH, became the Portfolios' distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Portfolios' agency
transactions. Certain other broker-dealers, continue to sell Portfolio shares to
the public as members of the selling group.

For the New York Portfolio, there are maximum initial sales charges of 4.00% and
1.00% for Class A and L shares, respectively. There is also a contingent
deferred sales charge ("CDSC") of 4.50% on Class B shares of the New York
Portfolio, which applies if redemption occurs within one year from 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 L shares also have a 1.00% CDSC,
which applies if redemption occurs within the first year of purchase. In certain
cases, Class A shares have a 1.00% CDSC, which applies if redemption occurs
within the first year of purchase. This CDSC only applies to those purchases of
Class A shares, which, when combined with current holdings of Class A shares,
equal or exceed $500,000 in the aggregate. These purchases do not incur an
initial sales charge.

For the six months ended September 30, 2000, SSB and CFBDS received sales
charges of approximately $463,000 and $37,000 on sales of the New York
Portfolio's Class A and L shares, respectively. In addition, for the six months
ended September 30, 2000, CDSCs paid to SSB were approximately:

                                             Class A      Class B     Class L

================================================================================

Pursuant to a Distribution Plan, the New York Money Market Portfolio pays a
distribution fee calculated at the annual rate of 0.10% of the average daily net
assets of its Class A shares. The New York Portfolio pays a service fee with
respect to Class A, B and L shares calculated at the annual rate of 0.15% of the
average daily net assets of each respective class. In addition, the New York
Portfolio pays a distribution fee with respect to Class B and L shares
calculated at the annual rates of 0.50% and 0.55% of the average daily net
assets of each class, respectively.

For the six months ended September 30, 2000, total Distribution Plan fees
incurred were:

================================================================================

6.   Futures Contracts

The New York Portfolio may from time to time enter into futures contracts.

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contracts. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by marking to market on a daily basis to reflect the
market value of the contract at the end of each day's trading. Variation margin
payments are received or made and recognized as assets due from or liabilities
due to broker, depending upon whether unrealized gains or losses are incurred.
When the contract is closed, the Portfolio records a realized gain or loss equal
to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract.

The Portfolio enters into such contracts to hedge a portion of its portfolio.
The Portfolio bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At September 30, 2000, the Portfolio had no open futures contracts.

7.   Capital Loss Carryforward

At March 31, 2000, the New York Money Market Portfolio and the New York
Portfolio had, for Federal income tax purposes, approximately $29,300 and
$9,400,000, respectively, of unused capital loss carryforwards available to
offset future capital gains expiring March 31, 2008. 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.

8.   Shares of Beneficial Interest

At September 30, 2000, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolios have
the ability to issue multiple classes of shares. Each share of a class
represents an identical interest in its respective Portfolio and has the same
rights, except that each class bears certain expenses specifically related to
the distribution of its shares.

At September 30, 2000, total paid-in capital amounted to the following for each
Portfolio and their respective classes:

A MESSAGE FROM THE CHAIRMAN

[PHOTO] HEATH B. MCLENDON CHAIRMAN

For years, individuals and businesses have looked to the investment
professionals of SSB Citi Fund Management LLC ("SSB Citi") for thoughtful
insights and advice. For some, the solution has been an investment strategy,
incorporating multiple stock, bond and money market mutual funds. Others have
invested with specific portfolio managers who are recognized for their insights
and record. Since the introduction of the first money fund in 1972, the
explosive growth of money funds has gone hand in hand with the growth of the
entire mutual fund industry. Over the last 28 years, millions of investors
worldwide have made money market funds a key part of their investment
portfolios. While all investments involve some degree of risk, money market
funds provide investors with an opportunity to earn current short-term interest
rates with a higher degree of liquidity than most other types of mutual funds.

For those of you who are new shareholders, I would like to extend a warm welcome
to you on behalf of everyone here at SSB Citi. The Smith Barney Muni
Funds--Massachusetts Money Market Portfolio ("Portfolio") seeks to provide
tax-exempt income(1) from both federal income taxes and Massachusetts personal
income taxes by seeking to invest in a portfolio of high quality short-term
municipal obligations selected for liquidity and stability of principal.
Portfolio managers, Joseph P. Deane and Joseph Benevento, use a system of
fundamental credit analysis to build the Portfolio's holdings. They only select
securities of issuers that they believe present minimal credit risk.

When you invest with SSB Citi, you can do so with the confidence that your
interests come first, your investment success is paramount and that the ultimate
in resources is being committed to your financial future. Thank you for
investing with us.

Sincerely,

/s/  Heath B. McLendon

SHAREHOLDER LETTER


[PHOTO] JOSEPH P. DEANE VICE PRESIDENT

[PHOTO] JOSEPH BENEVENTO VICE PRESIDENT


DEAR SHAREHOLDER:

We are pleased to provide the semi-annual report for the Smith Barney Muni
Funds--Massachusetts Money Market Portfolio ("Portfolio") for the period ended
 September 30, 2000. In this report we have summarized the period's prevailing
economic and market conditions and outlined our investment strategy. The
information provided in this letter represents the opinion of the managers and
is not intended to be a forecast of future events, a guarantee of future results
nor investment advice.

Please note that your investment in the Portfolio is neither insured, nor
guaranteed, by the Federal Deposit Insurance Corporation or any other government
agency. Although the Portfolio seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Portfolio.

MASSACHUSETTS ECONOMIC HIGHLIGHTS(1)
Massachusetts' economy remains healthy, with continued growth of a more diverse,
vibrant, and broadened economic base led by high-tech, health care, higher
education and business service industries. The evolution of the state's economy
has resulted in strong job growth in generally higher paying industries, greater
mobility for skilled workers and an improved overall level of competitiveness.

Massachusetts has demonstrated strong fiscal discipline and management evidenced
by nine consecutive annual operating surpluses through fiscal year 2000.
Moreover, the state anticipates another operating surplus in fiscal 2001. In our
opinion, the outlook for Massachusetts remains favorable. Going forward, we
think the biggest challenges facing the state is balancing tax cuts and capital
and debt plans while maintaining its strong financial position.

INVESTMENT STRATEGY AND PERFORMANCE UPDATE
As previously noted, the Portfolio seeks to provide investors with income exempt
from federal income and Massachusetts state personal income taxes(2) by
investing in high-quality, short-term Massachusetts municipal obligations
selected for liquidity and stability of principal.

As of September 30, 2000, the Portfolio's seven-day current yield was 4.00%. The
Portfolio's seven-day effective yield(3) -- which reflects compounding -- was
4.08%.

During the six months ended September 30, 2000, we increased the Portfolio's
average maturity(4) target to a 65- to 70-day range. We have extended the
Portfolio's average maturity by buying what we deem to be high-quality liquid
municipal notes.

The Portfolio's increased average maturity during the period reflects:

     - A slowdown in economic activity over the near-term; and
     - Less supply of high-quality short-term municipal paper.

The record expansion of the U.S. economy has produced budget surpluses for many
state and local governments, which has decreased the need for short-term cash
flow financing.

ECONOMIC & MARKET OVERVIEW
Municipal bonds have been a very simple story throughout 2000. They started at
relatively inexpensive valuations and then rallied. Stable interest rates and a
robust economy with few excesses are painting a bullish picture for bonds in
general, while declining new issue supply may be further bolstering the
municipal bond market. In addition, a vibrant national economy has produced
large cash surpluses in many states and municipalities, causing general
improvement in the credit quality of municipal securities and giving some
comfort to many investors regarding the credit worthiness of their securities.

From our point of view, recent months have been good for the municipal market.
As the stock market endured its correction in March and April 2000, municipal
bonds forged ahead slowly but relentlessly. In our view, the municipal markets
are in a state of flux that may lead to greater opportunities. The federal
government conducted a buy back of long-term government bonds early in 2000,
which drove down yields.

(2) PLEASE NOTE A PORTION OF THE INCOME FROM THE PORTFOLIO MAY BE SUBJECT TO THE
    ALTERNATIVE MINIMUM TAX ("AMT").
(3) THE SEVEN-DAY EFFECTIVE YIELD IS CALCULATED SIMILARLY TO THE SEVEN-DAY YIELD
    BUT, WHEN ANNUALIZED, THE INCOME EARNED BY AN INVESTMENT IN THE PORTFOLIO OR
    THE CLASS IS ASSUMED TO BE REINVESTED. THE EFFECTIVE YIELD WILL BE SLIGHTLY
    HIGHER THAN THE YIELD BECAUSE OF THE COMPOUNDING EFFECT OF THE ASSUMED
    REINVESTMENT.
(4) AVERAGE MATURITY REFERS TO THE AVERAGE DATE ON WHICH THE PRINCIPAL IS
    REQUIRED TO BE PAID ON THE BOND.

<PAGE>

On May 16, 2000, the Federal Reserve Board ("Fed") increased the federal funds
rate ("fed funds rate")(5) by 50 basis points(6), however, the supply and demand
imbalance in the short-term municipal market put pressures on both the municipal
note and the Variable Rate Demand Obligation ("VRDO")(7) markets and at times,
defied rising rates.

During the six months ended September 30, 2000, the Bond Buyer One-Year
Municipal Note Index(8) increased by approximately 60 basis points to a high of
4.64% in early May of 2000. The market then looked to June, which is the fiscal
year end for most state and local governments, however less issuance was
announced for fiscal year 2001 and as a result the Bond Buyer One-Year Municipal
Note Index reacted by falling to a 4.20% by late September.

In the VRDO market, which represents the shorter end of the municipal money
market yield curve, supply and demand imbalances have led to increased
volatility during periods of cyclical cash flows. Over the normal course of the
year, tax-exempt money funds tend to experience large cyclical cash flows. For
example, during the month of April, yields for VRDOs in Massachusetts surged as
tax-exempt money funds experienced large redemptions relating to income tax
payments. During the month of July, when tax-exempt money funds experience large
inflows from bond coupon collections and bond calls, yields quickly retreated to
levels more expensive than their taxable equivalents.

Going forward, we believe there may be a greater amount of supply of short-term
municipal securities in Massachusetts that become available from decade old
municipal bond issuance. The older issuance are now eligible either by
pre-refunding(9) or by maturing in 13 months or less.

(5) FED FUNDS RATE IS THE INTEREST RATE THAT BANKS WITH EXCESS RESERVES AT A
    FEDERAL RESERVE DISTRICT BANK CHARGE OTHER BANKS THAT NEED OVERNIGHT LOANS.
    THE FED FUNDS RATE OFTEN POINTS TO THE DIRECTION OF U.S. INTEREST RATES.
(6) A BASIS POINT IS 0.01% OR ONE ONE-HUNDREDTH OF A PERCENT.
(7) VRDOS ARE DEMAND INSTRUMENTS THAT USUALLY HAVE AN INDICATED MATURITY OF
    MORE THAN ONE YEAR, BUT THEY CONTAIN A DEMAND FEATURE THAT ENABLES THE
    HOLDER TO REDEEM THE INVESTMENT ON NO MORE THAN 30 DAYS NOTICE. THESE
    INSTRUMENTS PROVIDE FOR AUTOMATIC ADJUSTMENT OF NEW RATES ON SET DATES AND
    ARE GENERALLY SUPPORTED BY LETTERS OF CREDIT ISSUED BY DOMESTIC OR FOREIGN
    BANKS.
(8) THE BOND BUYER ONE-YEAR MUNICIPAL NOTE INDEX IS COMPRISED OF TEN LARGE
    MUNICIPAL NOTE ISSUES RATED MIG 1 BY MOODY'S INVESTORS SERVICE, INC. OR
    SP+/SP-1 BY STANDARD & POOR'S RATINGS SERVICE, REPRESENTING A CROSS SECTION
    OF THE MUNICIPAL NOTE MARKET. PLEASE NOTE AN INVESTOR CANNOT INVEST
    DIRECTLY IN AN INDEX

(9) PRE-REFUNDING OCCURS WHEN AN ISSUER REFINANCES DEBT THROUGH THE ISSUANCE OF
    A NEW BOND DEAL. THE PROCEEDS FROM THE NEW BOND SALE ARE PLACED IN AN
    ESCROW ACCOUNT AND ARE USED TO RETIRE THE DEBT TO THE EARLIEST CALL DATE.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.  SIGNIFICANT ACCOUNTING POLICIES

The Massachusetts Money Market Portfolio ("Portfolio") is a separate investment
portfolio of the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company and consists of this
Portfolio and eight other separate investment portfolios: Florida, Georgia,
Limited Term, New York, National, Pennsylvania, California Money Market and New
York Money Market Portfolios. The financial statements and financial highlights
for the other portfolios are presented in separate shareholder reports.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) the Portfolio uses
the amortized cost method for valuing investments; accordingly, the cost of
securities plus accreted discount, or minus amortized premium, approximates
value; (c) gains or losses on the sale of securities are calculated by using the
specific identification method; (d) interest income, adjusted for amortization
of premium and accretion of original issue discount, is recorded on accrual
basis; market discount is recognized upon the disposition of the security; (e)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (f) direct expenses are charged to each portfolio and each class;
management fees and general fund expenses are allocated on the basis of relative
net assets; (g) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles; (h) the Portfolio 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.  PORTFOLIO CONCENTRATION

Since the Portfolio invests primarily in obligations of issuers within
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 Portfolio declares and records a dividend of substantially all its net
investment income on each business day. Such dividends are paid or reinvested
monthly in fund shares on the payable date. Furthermore, the Portfolio intends
to satisfy conditions that will enable interest from municipal securities, which
is exempt from regular Federal income tax and from designated state income
taxes, to retain such tax-exempt status when distributed to the shareholders of
the Portfolio.

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

4.  MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Portfolio. The Portfolio pays
SSBC a management fee calculated at an annual rate of 0.50% on the first $2.5
billion of average daily net assets; 0.475% on the next $2.5 billion and 0.45%
on the average daily net assets in excess of $5 billion. This fee is calculated
daily and paid monthly. For the six months ended September 30, 2000, SSBC waived
a portion of their management fee amounting to $9,988.

Citi Fiduciary Trust Comany ("CFTC"), formerly known as Smith Barney Private
Trust Company, another subsidiary of Citigroup, acts as the Portfolio's
transfer agent and PFPC Global Fund Services ("PFPC") acts as the Portfolio's
sub-transfer agent. CFTC receives account fees and asset-based fees that vary
according to the size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder
accounts and is paid by CFTC. For the six months ended September 30, 2000,
the Portfolio paid transfer agent fees of $15,388 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Portfolio's distributor replacing CFBDS, Inc. In addition,
SSB acts as the primary broker for the Portfolio's agency transactions. Certain
other broker-dealers, continue to sell Portfolio shares to the public as a
members of the selling group.

Pursuant to a Distribution Plan, the Portfolio pays a distribution fee with
respect to Class A shares calculated at the annual rate of 0.10% of the average
daily net assets of that class.

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

A MESSAGE FROM THE CHAIRMAN

The new millennium, so far, has been marked by higher volatility and concerns
that the bull market in stocks may be running out of steam. At SSB Citi Fund
Management LLC ("SSB Citi"), we have instituted many positive changes, with the
ultimate goal of offering our investors a well-rounded menu of stock and bond
funds that can be tailored to a wide range of investment objectives.

We believe that your serious money demands professional management. Since 1937,
Smith Barney has managed the serious money of individuals, their families and
their businesses. Today, with over $395.5 billion in assets under management,1
we believe that SSB Citi offers choices and solutions, uniting the distinguished
history of Smith Barney with the unparalleled global reach of its parent,
Citigroup.

The Smith Barney family of funds represents a complex with a 60-year history of
investment expertise. In addition, Smith Barney is currently conducting an
extensive advertising campaign, highlighting a selection of the most popular
Smith Barney mutual funds and the investment professionals who manage them.

The Smith Barney Muni Funds - Florida Portfolio ("Portfolio") seeks as high a
level of income exempt from federal income taxes(2) as is consistent with
prudent investing. The Portfolio generally favors municipal securities that
enable its shares to be exempt from the Florida intangibles tax. Experienced
manager Peter Coffey and his team seek to create a built-in income stream for
the long-term. Coffey and his team believe the municipal bonds appear to be
attractively priced relative to underlying inflation rates in an environment of
light supply and muted institutional demand.

When you invest with SSB Citi, you can do so with the confidence that your
interests come first, your investment success is paramount and that the ultimate
in resources is being committed to your financial success.

SHAREHOLDER LETTER

DEAR SHAREHOLDER:
We are pleased to provide the semi-annual report for the Smith Barney Muni Funds
-- Florida Portfolio ("Portfolio") for the period ended September 30, 2000. In
this report we have summarized the period's prevailing economic and market
conditions and outlined our investment strategy. The information provided in
this letter represents the opinion of the manager and is not intended to be a
forecast of future events, a guarantee of future results nor investment advice.

Further, there is no assurance that certain securities will remain in or out of
the Portfolio. Please refer to pages 11 through 19 for a list and percentage
breakdown of the Portfolio's holdings. Also, please note any discussion of the
Portfolio's holdings is as of September 30, 2000 and is subject to change. A
detailed summary of the Portfolio's performance can be found in the appropriate
sections that follow. We hope you find this report to be useful and informative.

PERFORMANCE AND INVESTMENT STRATEGY
For the six months ended September 30, 2000, the Portfolio's Class A shares,
without and with sales charges returned 4.06% and a negative 0.11%,
respectively. In comparison, the Lehman Brothers Municipal Bond Index ("Lehman
Index")(1) returned 3.97% for the same period.

Because we think the bond markets are likely to remain volatile in the near
term, we continue to favor a gradual approach into the market. We tend to favor
longer and intermediate maturities, where most of the benefits of the steep
positive slope of the municipal yield curve(2) can be obtained.

During the reporting period, average credit quality remained relatively high in
the Portfolio. Although quality spreads during the period have widened due to
earnings pressure, especially in hospital- and healthcare-related sectors, the
difference in yield between the highest quality issues and medium grade issues,
in our view, remained relatively modest. We think our proprietary research
enables us to invest in select medium-term credits for which perceived market
risk may be greater than our analysis otherwise indicates. Moreover, while no
guarantees can be made, we think our strategy may have the potential to increase
income over time.

-----------
1  The Lehman Index is a broad measure of the municipal bond market with
   maturities of at least one year. Please note an investor cannot invest
   directly in an index.

2  The yield curve is the graphical depiction of the relationship between the
   yield on bonds of the same credit quality but different maturities.

During the past six months, we took advantage of rising interest rates to
generate additional yield in-the Portfolio. We also looked to incorporate
additional call protection(3) into the Portfolio by selling off some of our
higher coupon bonds with shorter calls,(4) and replacing them with bonds that
have similar high coupon structure, but are not subject to early call.

One of the ways that we manage the Portfolio is that we seek to create a
built-in income stream for the long-term. To this end, we have generally focused
on investing in securities with high credit quality and good call protection, as
we believe these securities offer solid long-term values. Moreover, we have a
fairly long weighted average life(5) in the portfolio because we believe that
the risk of higher inflation at the present time is negligible. In addition, we
think our greater emphasis on call protection may provide our shareholders with
more consistent income if interest rates do in fact go down.

MARKET OVERVIEW AND OUTLOOK
The municipal bond market continues to be dominated by supply and demand factors
such as lower new issue volume, strong retail demand and very limited
institutional demand. In addition, the U.S. Treasury market also appears to be
influenced from its own supply and demand factors. The market has gotten so thin
as a result of collapsing supply that a handful of seemingly minor factors can
have a dramatic impact on yields across the entire U.S. Treasury yield curve.

In the overall bond market, yield spreads have narrowed and benchmark yield
levels have dropped by nearly a percentage point during the period in response
to evidence that underlying inflation risks have subsided and economic growth is
slowing down from the rapid 6% annual pace of the past year. We think there is a
good chance that the decline in yields has further to go. Yet, a host of
technical and other considerations may stall the market or cause yields to rise
temporarily, barring a dramatic new sign that the U.S. economic expansion is
slowing below an expected 3% to 4% annual pace.

We think conditions appear favorable for interest rates. First, on the
structural side, the massive federal surplus is fueling a collapse of U.S.
Treasury note and bond supply. On the cyclical side, potential sources of
inflation such as too strong consumer growth and a tight labor market, appear to
be moderating. However, temporary concerns remain in the form of heavy private
sector issuance, soaring energy costs and the upcoming Presidential and
Congressional elections.

-----------
3  Call protection is the length of time during which a security cannot be
   redeemed by the issuer.

4  Callable bonds are redeemable by the issuer before the scheduled maturity
   under specific conditions and at a stated price, which usually begins at a
   premium to par and declines annually. Bonds are usually "called" when
   interest rates fall so significantly that the issuer can save money by
   floating new bonds at lower rates

5  Average life is the length of time before the principal of debt issues is
   scheduled to be repaid through amortization or sinking fund.

<PAGE>

On the energy front, we believe that the recent price rises may act more like a
tax increase rather than as a spur to higher prices throughout the economy. That
is, as consumers spend more on gasoline and heating oil, they may moderate their
spending on discretionary items. Under this scenario, the results may be a
gradual slowing of growth rather than a spike in underlying inflation.

The spectacular productivity gains of this year have kept underlying inflation
at extremely comfortable levels, with the "core consumption deflator," a
favorite measure of Federal Reserve Board ("Fed") Chairman Alan Greenspan,
running at a miniscule 0.8% annual rate for the past six months. A second key
point, related to the first, is that we think the likelihood of significant
additional Fed tightening appears to be minimal.

New issue supply in the municipal bond market continues to trail far behind
levels reached in 1998 and 1999. Through mid-September 2000, volume was 21%
lower than 1999 levels, while full-year 1999 issuance had already declined 21%
from the 1998 peak. The main reason for the decline is the lack of refunding
volume. With interest rates still higher than they were during 1998 and the
first half of 1999, issuers have had little incentive to refund previous issues.

Individual investor demand for municipals has remained extremely strong, despite
the recent easing of yields from early 2000 levels. Given the small size of the
municipal bond market relative to the stock market, even a modest shift of
assets out of stocks into municipals can create an enormous amount of new demand
for municipal bonds. In short, we think municipal bonds seem to be attractively
priced relative to underlying inflation rates, in an environment of light supply
and muted or near-dormant institutional demand.

FLORIDA ECONOMIC HIGHLIGHTS(6)
Over the past few years, Florida's economy has grown and has become more
diversified. Florida's economy has gone from one that was once dominated by
farming and seasonal tourism to a service and trade economy with sustainable
insurance, banking and export industries, as well as becoming a greater
year-round attraction. Moreover, the economic success of the Sunshine State, in
part, can also be attributed to its positive business climate.

Florida's economic expansion has brought about the need for more infrastructure,
educational facilities, and other needs in order to meet growth in a state that
is currently the fourth largest in the U.S. However, despite these pressures and
considerable planned capital spending, debt has remained moderate at $1,013 per
capita and 3.7% of personal income. In our opinion, the

outlook for Florida remains bright. And while no guarantees can be made, we
believe the state's financial operations may continue to reflect the
better-than-expected trend of the past few years.

look forward to helping you pursue your financial goals in the future.

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect the deduction of the
     applicable sales charges with respect to Class A and L shares or the
     applicable contingent deferred sales charges ("CDSC") with respect to Class
     B and L shares.

(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A and L shares reflect the
     deduction of the maximum initial sales charge of 4.00% and 1.00%,
     respectively; and Class B shares reflect the deduction of a 4.50% CDSC,
     which applies if shares are redeemed within one year from 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 L shares also reflect the
     deduction of a 1.00% CDSC, which applies if shares are redeemed within the
     first year of purchase.

*    Inception dates for Class A, B and L shares are April 2, 1991, November 16,
     1994 and January 5, 1993, respectively.

+    Total return is not annualized, as it may not be representative of the
     total return for the year.

+  Hypothetical illustration of $10,000 invested in Class A shares at inception
   on April 2, 1991, assuming deduction of the maximum 4.00% sales charge at the
   time of investment and reinvestment of dividends (after deduction of
   applicable sales charges through November 6, 1994, and thereafter at net
   asset value) and capital gains, if any, at net asset value through September
   30, 2000. The Lehman Brothers Municipal Bond Index is a broad-based, total
   return index comprised of investment grade, fixed rate municipal bonds
   selected from issues larger than $50 million issued since January 1984. The
   Index is unmanaged and is not subject to the same management and trading
   expenses of a mutual fund. The performance of the Portfolio'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 (UNAUDITED)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("Standard & Poor's) -- Ratings from "AA" to
"BB" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

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 differ from the highest rated issues only in a small degree.

A    -- Bonds rated "A" have a strong capacity to pay interest and repay
     principal although they are 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, it faces 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.

Moody's Investors Service, Inc. ("Moody's") -- Numerical modifiers 1, 2, and 3
may be applied to each generic rating from "Aa" to "Baa", where 1 is the highest
and 3 the lowest-rating within its generic category.

Aaa  -- Bonds 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 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 as 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 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 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

BOND RATINGS (UNAUDITED) (CONTINUED)

Fitch IBCA, Inc. ("Fitch") -- Ratings from "AA" to "BBB" may be modified by the
addition of a plus (+) sign or minus (-) sign to show relative standings within
the major ratings categories.

AA   -- Bonds rated "AA" are considered to be investment grade and of very high
     credit quality. The obligor's ability to pay interest and/or dividends and
     repay principal is very strong.

A    -- Bonds and preferred stock considered to be investment grade and of high
     credit quality. The obligor's ability to pay interest and/or dividends and
     repay principal is considered to be strong, but may be more vulnerable to
     adverse changes in economic conditions and circumstances than debt or
     preferred securities with higher ratings.

BBB  -- Bonds rated "BBB" are considered to be investment grade and of
     satisfactory credit quality. The obligor's ability to pay interest or
     dividends and repay principal is considered to be adequate. Adverse changes
     in economic conditions and circumstances, however, are more likely to have
     adverse impact on these securities and, therefore, impair timely payment.
     The likelihood that the ratings of these bonds will fall below investment
     grade is higher than for securities with higher ratings.

NR   -- Indicates that the bond is not rated by Standard & Poor's, Moody's or
     Fitch.

SHORT-TERM SECURITY RATINGS (UNAUDITED)

SP-1 -- Standard & Poor's highest rating indicating very strong or strong
     capacity to pay principal and interest; those issues determined to possess
     overwhelming safety characteristics are denoted with a plus (+) sign.

A-1  -- Standard & Poor's highest commercial paper and variable rate demand
     obligation (VRDO) rating indicating that the degree of safely regarding
     timely payment is either overwhelming or very strong; those issues
     determined to possess overwhelming safety characteristics are denoted with
     a (+) sign.

VMIG 1 -- Moody's highest rating for issues having demand feature -- VRDO.

P-1  -- Moody's highest rating for commercial paper and for VRDO prior to the
     advent of the VMIG 1 rating.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

The Florida Portfolio ("Portfolio") is a separate investment portfolio of the
Smith Barney Muni Funds ("Funds"). The Fund, a Massachusetts business trust, is
registered under the Investment Company Act of 1940, as amended, as an open-end,
non-diversified management investment company. The Fund consists of this
Portfolio and eight other separate investment portfolios: Georgia, Limited Term,
National, New York, Pennsylvania, New York Money Market, California Money Market
and Massachusetts Money Market Portfolios. The financial statements and
financial highlights for the other portfolios are presented in separate
shareholder reports.

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 provided by an independent
pricing service that are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable
securities and various relationships between securities; (c) securities for
which market quotations are not available are valued in good faith at fair
market value by or under the direction of the Board of Trustees; (d) securities
maturing within 60 days are valued at cost plus accreted discount or minus
amortized premium, which approximates value; (e) gains or losses on the sale of
securities are calculated by using the specific identification method; (f)
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, (g) direct expenses are charged to each
class; management fees and general fund expenses are allocated on the basis of
relative net assets; (h) dividends and distributions to shareholders are
recorded on the ex-dividend date; (i) the Portfolio 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; (j) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles; and (k) 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.

it is subject to possible concentration risks associated with economic,
political, or legal developments or industrial or regional matters specifically
affecting Florida.

3. EXEMPT-INTEREST DIVIDENDS AND OTHER DISTRIBUTIONS

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

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

net assets. This fee is calculated daily and paid monthly.

the Portfolio's transfer agent and PFPC Global Fund Services ("PFPC") acts as
the Portfolio's sub-transfer agent. CFTC receives account fees and asset-based

for shareholder recordkeeping and financial processing for all shareholder
accounts and is paid by CFTC. For the six months ended September 30, 2000, the
Portfolio paid transfer agent fees of $21,185 to CFTC.

addition, SSB acts as the primary broker for the Portfolio's agency
transactions. Certain other broker-dealers, continue to sell Portfolio shares to
the public as members of the selling group.

There are maximum initial sales charges of 4.00% and 1.00% for Class A and L
shares, respectively. There is a contingent deferred sales charge ("CDSC") of
4.50% on Class B shares, which applies if redemption occurs within one year from
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 L shares also have
a 1.00% CDSC, which applies if redemption occurs within the first year of

6. FUTURES CONTRACTS

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contracts. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking-to-market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are made or received and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract.

The Portfolio enters into such contracts to hedge a portion of its portfolio.
The Portfolio bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At September 30, 2000, the Portfolio had no open futures contracts.

7. CAPITAL LOSS CARRYFORWARD

At March 31, 2000, the Portfolio had, for Federal income tax purposes,
approximately $2,430,000 of unused capital loss carryforwards available to
offset future capital gains expiring March 31, 2008. 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.

8. SHARES OF BENEFICIAL INTEREST

At September 30, 2000, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolio has the
ability to issue multiple classes of shares. Each share of a class represents an
identical interest in the Portfolio and has the same rights, except that each
class bears certain expenses related to the distribution of its shares.

At September 30, 2000, total paid-in capital amounted to the following for each
class:

A MESSAGE FROM THE CHAIRMAN

The new millennium, so far, has been marked by higher volatility and concerns
that the bull market in stocks may be running out of steam. At SSB Citi Fund
Management LLC ("SSB Citi"), we have instituted many positive changes, with the
ultimate goal of offering our investors a well-rounded menu of stock and bond
funds that can be tailored to a wide range of investment objectives.

We believe that your serious money demands professional management. Since 1937,
Smith Barney has managed the serious money of individuals, their families and
their businesses. Today, with over $395.5 billion in assets under management(1),
SSB Citi offers choices and solutions, uniting the distinguished history of
Smith Barney with the unparalleled global reach of its parent, Citigroup.

The Smith Barney family of funds represents a complex with a 60-year history of
investment expertise. In addition, Smith Barney is currently conducting an
extensive advertising campaign, highlighting a selection of the most popular
Smith Barney mutual funds and the investment professionals who manage them.

For those of you who are new shareholders, I would like to extend a warm welcome
to you on behalf of everyone here at SSB Citi. Both the Smith Barney Muni Funds
-- Georgia and Pennsylvania Portfolios seek as high a level of income exempt
from federal income taxes(2) as is consistent with prudent investing.
Experienced manager Peter Coffey and his team seek to create a built-in income
stream for the long-term. Coffey and his team believe municipal bonds appear to
be attractively priced relative to underlying inflation rates in an environment
of light supply and muted institutional demand.

SHAREHOLDER LETTER

Photo: Peter M. Coffey   Vice President

DEAR SHAREHOLDER:

We are pleased to provide the semi-annual report for the Smith Barney Muni Funds
Georgia and Pennsylvania Portfolios ("Portfolio(s)") for the period ended
September 30, 2000. In this report we have summarized the period's prevailing
economic and market conditions and outlined our investment strategy. The
information provided in this letter represents the opinion of the manager and is
not intended to be a forecast of future events, a guarantee of future results
nor investment advice.

Further, there is no assurance that certain securities will remain in or out of
the Portfolios. Please refer to pages 13 through 22 for a list and percentage
breakdown of the Portfolios' holdings. Also, please note that any discussion of
the Portfolios' holdings is as of September 30, 2000 and is subject to change. A
detailed summary of the Portfolios' performance can be found in the appropriate
sections that follow. We hope you find this report to be useful and informative.

MARKET AND ECONOMIC OVERVIEW

The municipal bond market continues to be dominated by supply and demand factors
such as lower new issue volume, strong retail demand and very limited
institutional demand. In addition, the U.S. Treasury market also appears to be
influenced from its own supply and demand factors. The market has gotten so thin
as a result of collapsing supply that a handful of seemingly minor factors can
have a dramatic impact on yields across the entire U.S. Treasury yield curve.(1)

In the overall bond market, yield spreads have narrowed and benchmark yield
levels have dropped by nearly a percentage point during the period in response
to evidence that underlying inflation risks have subsided and economic growth is
slowing down from the rapid 6% annual pace of the past year. We think there is a
good chance that the decline in yields has further to go. Yet, a host of
technical and other considerations may stall the market or cause yields to rise
temporarily, barring a dramatic new sign that the U.S. economic expansion is
slowing below an expected 3% to 4% annual pace.

We think conditions appear favorable for interest rates. First, on the
structural side, the massive federal surplus is fueling a collapse of U.S.
Treasury supply.

     yield on bonds of the same credit quality but different maturities.

<PAGE>

On the cyclical side, potential sources of inflation such as strong consumer
growth and a tight labor market, appear to be moderating. However, there are
temporary concerns, in the form of heavy private sector issuance, soaring energy
costs and the upcoming Presidential and Congressional elections.

On the energy front, we believe that the recent price rises in this single
sector may act more like a tax increase rather than as a spur to high prices
throughout the economy. That is, as consumers spend more on gasoline and heating
oil, they may moderate their spending on discretionary items. The spectacular
productivity gains that have shown up this year have kept underlying inflation
at extremely comfortable levels, with the "core consumption deflator," a
favorite measure of Federal Reserve Board ("Fed") Chairman Alan Greenspan,
running at a miniscule 0.8% annual rate for the past six months. A second key
point, related to the first, is that we think the likelihood of significant
additional Fed tightening appears to be minimal.

New issue supply continues to trail far behind levels reached in 1998 and 1999.
Through mid-September 2000, volume was 21% lower than 1999 levels, whereas
full-year 1999 issuance has already declined 21% from the 1998 peak. The main
reason for the decline is the lack of refunding volume. With interest rates
still higher than they were during 1998 and the first half of 1999, issuers have
had little incentive to refund previous issues.

Individual investor demand for municipals has remained extremely strong, despite
the recent easing of yields from early 2000 levels. Given the small size of the
municipal bond market relative to the stock market, even a modest shift of
assets out of stocks into municipals can create an enormous amount of new demand
for municipal bonds. In short, we think municipal bonds appear to be
attractively priced relative to underlying inflation rates, in an environment of
very light supply and muted or near-dormant institutional demand.

GEORGIA PORTFOLIO'S PERFORMANCE AND INVESTMENT STRATEGY
The Georgia Portfolio seeks as high a level of current income exempt from
federal income taxes and Georgia personal income taxes as is consistent with
prudent investing.(2)

For the six months ended September 30, 2000, the Portfolio's Class A shares,
without and with sales charges, returned 4.04% and a negative 0.14%,
respectively. In comparison, the Lehman Brothers Municipal Bond Index ("Lehman
Index")(3) returned 3.97% for the same period.

3    The Lehman Index is a broad measure of the municipal bond market with
     maturities of at least one year. Please note an investor cannot invest
     directly in an index.

At the end of the period the Portfolio's largest holdings were concentrated in
education bonds (16.9%), water and sewer bonds (14.0%) and escrowed to maturity
bonds (10.1%).

GEORGIA ECONOMIC HIGHLIGHTS(4)

Georgia's economy continues to be one of the nation's most prosperous, due in
large part to its conservative financial operations, superior debt management
policies as well as the state's growing leadership in technology, communication
and commerce. The Peachtree State's economic progress, which includes steady
improvement in the state's economic diversification and income levels, are the
main reasons why Georgia has an excellent credit standing.

Over the past few years, Georgia's economy has grown considerably. Most notably
was this past year, with revenues for 1999-2000 increasing approximately 8% from
the previous year, as compared to the budgeted amount, which was a little less
than the collection in 1998-1999.

Georgia's economic outlook, in our opinion, remains extremely favorable.
Georgia's trade, service, and transportation-oriented diversified economy should
continue to generate superior revenue growth, and, that in turn should enable
the state to meet its growing infrastructure needs.

PENNSYLVANIA PORTFOLIO'S PERFORMANCE AND INVESTMENT STRATEGY
The Pennsylvania Portfolio seeks as high a level of income exempt from federal
income taxes and Pennsylvania personal income taxes as is consistent with
prudent investing.(5)

For the six months ended September 30, 2000, the Portfolio's Class A shares,
without and with sales charges, returned 4.52% and 0.32%, respectively. In
comparison, the Lehman Index returned 3.97% for the same period.

At the end of the period the Portfolio's largest holdings were concentrated in
hospital bonds (22.3%), education bonds (12.8%) and industrial development bonds
(10.7%).

PENNSYLVANIA ECONOMIC HIGHLIGHTS(6)
Pennsylvania's economy has changed over the past decade and has made tremendous
strides in the transformation of its economy. Pennsylvania combines the
characteristics of both a northeastern and midwestern state. In recent years,
the importance of the state's manufacturing sector has sharply declined as

service industries continue to grow. While manufacturing remains more
significant for Pennsylvania than the rest of the nation, the Commonwealth has
been making a concerted effort to evolve from a "lumbering industrial-age giant"
to a bona fide high-tech leader.

Pennsylvania's economy strengthened during the period and the state's debt
position has improved consistently over the past few years. The state has
completed eight years with surplus operations, and in the past five years,
revenue has been well above estimates. We anticipate that this trend should
continue for the remainder of 2000.

In our opinion, the economic outlook for Pennsylvania is positive because the
state has targeted various areas of economic development, building reserves that
have enabled the state to enjoy operating stability and further diversify its
economy, with employment growth in all sectors. This, together with investment
in infrastructure, in our opinion, may continue to improve Pennsylvania's future
prospects.

In closing, thank you for investing in the Smith Barney Muni Funds -- Georgia
and Pennsylvania Portfolios.

Sincerely,

  + Hypothetical illustration of $10,000 invested in Class A shares at inception
    on April 4, 1994, assuming a 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 September 30, 2000. The Lehman Brothers
    Georgia Municipal Bond Index (consisting of Georgia municipal bonds) is a
    sub-index of the Lehman Brothers Municipal Bond Index, a broad-based, total
    return index comprised of investment grade, fixed rate municipal bonds
    selected from issues larger than $50 million issued since January 1991. Each
    index is unmanaged and is not subject to the same management and trading
    expenses of a mutual fund. The performance of the Portfolio'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.

     applicable contingent deferred sales charges ("CDSC") with respect to Class
     B and L shares.

(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A and L shares reflect the
     deduction of the maximum sales charge of 4.00% and 1.00%, respectively;

     shares are redeemed within 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 L shares also reflect the deduction
     of a 1.00% CDSC, which applies if shares are redeemed within the first year
     of purchase.

BOND RATINGS (UNAUDITED)

The definitions of the applicable rating symbols are set forth below:


Standard & Poor's Ratings Service ("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.

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 differ from the highest rated issues only in a small
         degree.
A  --    Bonds rated "A" have a strong capacity to pay interest and repay
         principal although they are 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" and "B" are regarded, on balance, as predominantly
and B    speculative with respect to the issuer's capacity to pay interest
         and repay principal in accordance with the terms of the obligation.
         "BB" indicates the lowest degree of speculation and "B" the highest
         degree of speculation. While such bonds will likely have some quality
         and protective characteristics, these are outweighed by large
         uncertainties or major risk exposures to adverse conditions.


Moody's Investors Service Inc.
("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
         rating within its generic category.

Aaa --   Bonds 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 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 as 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 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 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 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, and thereby not
         well safeguarded during both good and bad times over the future.
         Uncertainty of position characterizes in this class.

  BOND RATINGS (UNAUDITED) (CONTINUED)

Fitch IBCA, Inc. ("Fitch") -- Ratings may be modified by the addition of a plus
(+) sign or minus (-) sign to show relative standings within the major ratings
categories.

BBB --   Bonds rated "BBB" by Fitch currently have a low expectation of
         credit risk. The capacity for timely payment of financial commitments
         is considered to be adequate. Adverse changes in economic conditions
         and circumstances, however, are more likely to impair this capacity.
         This is the lowest investment grade category assigned by Fitch.

NR --    Indicates that the bond is not rated by Standard & Poor's, Moody's
         or Fitch.

  SHORT-TERM SECURITY RATINGS (UNAUDITED)

SP-1 --  Standard & Poor's highest rating indicating very strong or strong
         capacity to pay principal and interest; those issues determined to
         possess overwhelming safety characteristics are denoted with a plus (+)
         sign.
A-1 --   Standard & Poor's highest commercial paper and variable-rate demand
         obligation (VRDO) rating indicating that the degree of safely regarding
         timely payment is either overwhelming or very strong; those issues
         determined to possess overwhelming safety characteristics are denoted
         with a (+) sign.
P-1 --   Moody's highest rating for commercial paper and for VRDO prior to
         the advent of the VMIG 1 rating.
VMIG 1-- Moody's highest rating for issues having demand feature-- VRDO.
VMIG 2-- Moody's second highest rating for issues having a demand feature--
         VRDO.

  NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.   SIGNIFICANT ACCOUNTING POLICIES

The Georgia and Pennsylvania Portfolios ("Portfolios") are separate investment
portfolios of the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as an open-end non-diversified management investment company and
consists of these Portfolios and seven other separate investment portfolios:
Florida, New York, National, Limited Term, California Money Market,
Massachusetts Money Market and New York Money Market portfolios. The financial
statements and financial highlights for the other portfolios are presented in
separate shareholder reports.

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 bid and ask prices provided by an independent pricing
service that are based on transactions in municipal obligations, quotations from
municipal bond dealers, market transactions in comparable securities and various
relationships between securities; (c) securities for which market quotations are
not available will be valued in good faith at fair value by or under the
direction of the Board of Trustees; (d) securities maturing within 60 days are
valued at cost plus accreted discount or minus amortized premium, which
approximates value; (e) gains or losses on the sale of securities are calculated
by using the specific identification method; (f) interest income, adjusted for
amortization of premium and original issue discount, is recorded on an accrual
basis; market discount is recognized upon the disposition of the security; (g)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (h) direct expenses are charged to each Portfolio and each class;
management fees and general fund expenses are allocated on the basis of relative
net assets; (i) each Portfolio 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; (j) the
character of income and gains to be distributed are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles. At March 31, 2000, reclassifications were made to the capital
accounts of Georgia Portfolio and Pennsylvania Portfolio to reflect permanent
book/tax differences and income and gains available for distributions under
income tax regulations. Accordingly, for the Georgia Portfolio, a portion of
accumulated net realized loss amounting to $31,944 was reclassified to paid-in
capital. Net investment income, net realized gains and net assets were not
affected by these changes; and (k) estimates and assumptions are required to be
made regarding assets, liabilities and changes in net assets resulting from
operations when

<PAGE>

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)


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.   PORTFOLIO CONCENTRATION

Since the Georgia and Pennsylvania Portfolios invest primarily in obligations of
issuers within Georgia and Pennsylvania, respectively, each Portfolio is subject
to possible concentration risks associated with economic, political, or legal
developments or industrial or regional matters specifically affecting the
respective state in which it invests.

3.   EXEMPT-INTEREST DIVIDENDS AND OTHER DISTRIBUTIONS

Each Portfolio intends to satisfy conditions that will enable interest from
municipal securities, which is exempt from regular Federal income tax and from
designated state income taxes, to retain such tax-exempt status when distributed
to the shareholders of the Portfolio.

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

4.   MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS

SSB Citi Fund Management LLC("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH"), which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Fund. The Portfolios pay SSBC a
management fee calculated at an annual rate of 0.45% of their respective average
daily net assets. This fee is calculated daily and paid monthly. For the six
months ended September 30, 2000, SSBC waived management fees of $61,360 for the
Pennsylvania Portfolio.

Citi Fiduciary Trust Company ("CFTC"), another subsidiary of Citigroup, acts as
the Fund's transfer agent and PFPC Global Fund Services ("PFPC") acts as the
Fund's sub-transfer agent. CFTC receives account fees and asset-based fees that
vary according to account size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder accounts
and is paid by CFTC. During the six months ended September 30, 2000, the
Portfolios paid transfer agent fees totaling $14,866 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Fund's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSBacts as the primary broker for the Fund's portfolio agency
transactions. Certain other broker-dealers continue to sell Portfolio shares to
the public as members of the selling group.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)


There are maximum initial sales charges of 4.00% and 1.00% for Class A and L
shares, respectively. 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 by 1.00% per year until no CDSC is incurred. Class L shares also have a
1.00% CDSC, which applies if redemption occurs within the first year of
purchase. In certain cases, Class A shares have a 1.00% CDSC, which applies if
redemption occurs within the first year of purchase. This CDSC only applies to
those purchases of Class A shares, which, when combined with current holdings of
Class A shares, equal or exceed $500,000 in the aggregate. These purchases do
not incur an initial sales charge.

For the six months ended September 30, 2000, CDSCs paid to SSB and sales charges
received by SSB and CFBDS were approximately:

Pursuant to a Distribution Plan, the Portfolios pay a service fee with respect
to Class A, B and L shares calculated at an annual rate of 0.15% of the average
daily net assets of each respective class. The Portfolios also pay a
distribution fee with respect to Class B and L shares calculated at an annual
rate of 0.50% and 0.55% of the average daily net assets of each class,
respectively.

For the six months ended September 30, 2000, total Distribution Plan fees
incurred were:

================================================================================

6.   FUTURES CONTRACTS

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contracts. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking to market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are made or received and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Portfolio records a realized gain or
loss equal to the difference between the proceeds from (or cost of) the closing
transactions and the Portfolio's basis in the contract.

The Portfolio enters into such contracts to hedge a portion of its portfolio.
The Portfolio bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At September 30, 2000, the Portfolios had no open futures contracts.

7.   TRANSFER OF NET ASSETS

On December 10, 1999, the Georgia Portfolio acquired the assets and certain
liabilities of the Alterman Investment Fund, Inc. ("Alterman Fund") pursuant to
a plan of reorganization approved by Alterman Fund shareholders on December 7,
1999. Total Class A shares issued by the Georgia Portfolio and the total net
assets of the Alterman Fund and the Georgia Portfolio on the date of the
transfer were as follows:

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

The total net assets of the Alterman Fund before acquisition included unrealized
appreciation of $5,627. Total net assets of the Georgia Portfolio immediately
after the transfer were $68,132,076. The transaction was structured to qualify
as a tax-free reorganization under the Internal Revenue Code of 1986, as
amended.

8.   CAPITAL LOSS CARRYFORWARDS

At March 31, 2000, the Georgia Portfolio and Pennsylvania had, for Federal
income tax purposes, approximately $1,015,300 and $668,000, respectively, of
unused capital loss carryforwards available to offset future capital gains. To
the extent that these capital 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 March 31 of the year indicated:

9.   SHARES OF BENEFICIAL INTEREST

At September 30, 2000, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolios have
the ability to issue multiple classes of shares. Each share of a class
represents an identical interest in its respective Portfolio and has the same
rights, except that each class bears certain expenses specifically related to
the distribution of its shares.

At September 30, 2000, total paid-in capital amounted to the following for each
class and their respective Portfolio:

For years, individuals and businesses have looked to the investment
professionals of SSB Citi Fund Management LLC ("SSB Citi") for thoughtful
insights and advice. For some, the solution has been an investment strategy
incorporating multiple stock, bond and money market mutual funds. Others have
invested with specific portfolio managers who are recognized for their insights
and record.

Since the introduction of the first money fund in 1972, the explosive growth of
money funds has gone hand in hand with the growth of the entire mutual fund
industry. Over the last 28 years, millions of investors worldwide have made
money market funds a key part of their investment portfolios. While all
investments involve some degree of risk, money market funds provide investors
with an opportunity to earn current short-term interest rates with a higher
degree of liquidity than most other types of mutual funds.(1)

For those of you who are new shareholders, I would like to extend a warm welcome
to you on behalf of everyone here at SSB Citi. The Smith Barney Muni Funds
California Money Market Portfolio ("Portfolio") seeks to provide tax-exempt
income(2) from both federal income taxes and California personal taxes by
seeking to invest in a portfolio of high quality short-term municipal
obligations selected for liquidity and stability of principal. Portfolio
managers Joseph Deane and Joseph Benevento use a system of fundamental credit
analysis to identify what they deem to be undervalued sectors and individual
securities. They only select securities of issuers that they believe present
minimal credit risk.

1  PLEASE NOTE THAT AN INVESTMENT IN A MONEY MARKET FUND IS NOT INSURED NOR
   GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION ("FDIC") OR ANY OTHER
   GOVERNMENT AGENCY. ALTHOUGH MONEY MARKET FUNDS SEEK TO PRESERVE THE VALUE OF
   YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING
   IN A MONEY MARKET FUND.

   THE ALTERNATIVE MINIMUM TAX ("AMT").

PERFORMANCE UPDATE
The Portfolio seeks to provide investors with income exempt from federal income

CALIFORNIA ECONOMIC HIGHLIGHTS(3)

California has experienced a remarkable turnaround since the early 1990's when
it was experiencing its worst economic downturn since the Great Depression.
California has been able to recreate its economy to meet the challenges of the
New Economy.

California's high-tech manufacturing industry continues to set records in sales,
profits, exports, and new venture capital financing and higher high-tech job
employment. In our opinion, California's job growth is a good measure of
economic growth and is expected to rise roughly 4% this year, the highest pace
in 16 years.

We think California's economic resurgence may continue to effectively put
California on a more solid financial footing. We also believe that California
should remain a competitive economic force for many years to come due in large
part to its strong employment growth, rising real estate values and an annual
state Gross Domestic Product ("GDP")(4) of more than $1 trillion.

MARKET OVERVIEW AND OUTLOOK

Municipal bonds have been a very simple story throughout 2000. They started at
relatively inexpensive valuations and then rallied. Stable interest rates and a
robust economy with few excesses have helped to paint a bullish picture for
bonds in general, while declining new issue supply may be further bolstering the
municipal bond market. In addition, a vibrant national economy has produced
large cash surpluses in many states and municipalities, causing general
improvement in the credit quality of municipal securities and giving comfort to
many investors regarding the credit worthiness of their securities.

From our point of view, recent months have been a positive period for the
municipal bond market. As the stock market declined in March and April 2000,
municipal bonds forged ahead slowly but relentlessly. In our view, the municipal
bond market is in a state of flux that may lead to greater opportunities. The
federal government conducted a buy back of long-term government bonds early in
2000, which drove down yields.

<PAGE>

On May 16, 2000, the Federal Reserve Board ("Fed") increased the federal funds
rate ("fed funds rate")(5) by 50 basis points, however, the supply and demand
imbalance in the short-term municipal market put pressures on both the municipal
note and the Variable Rate Demand Obligation ("VRDO")(6) markets and at times,
defied rising rates.

During the period, the Bond Buyer One Year Municipal Note Index(7) increased by
approximately 60 basis points to a high of 4.64% in early May of 2000. The
market then looked to June, which is the fiscal year end for most state and
local governments, however less issuance was announced for fiscal year 2001 and
as a result the Bond Buyer 1 Year Note Index reacted by falling to a 4.20% by
late September.

In the VRDO market, which represents the shorter end of the municipal money
market yield curve, supply and demand imbalances have led to increased
volatility during periods of cyclical cash flows. Over the normal course of the
year, tax-exempt money funds tend to experience large cyclical cash flows. For
example, during the month of April, yields for VRDOs in California surged as
tax-exempt money funds experienced large redemptions relating to income tax
payments. During the month of July, when tax-exempt money funds experience large
inflows from bond coupon collections and bond calls, yields quickly retreated to
levels more expensive than their taxable equivalents.

Going forward, we believe there may be a greater amount of supply of short-term
municipal securities in California that become available from decade old
municipal bond issuance. The older issuance are now eligible either by pre-
refunding(8) or by maturing in 13 months or less.

INVESTMENT STRATEGY

During the period, we increased the Portfolio's average maturity(9) target to a
65- to 70-day range. We have extended the Portfolio's average maturity by buying
what we deem to be high quality liquid municipal notes.

The Portfolio's increased average maturity reflects:

     - A slowdown in economic activity over the near-term; and
     - Less supply of high quality short-term municipal paper.

The record expansion of the U.S. economy has produced budget surpluses for many

INVESTMENT STRATEGY

During the period, we increased the Portfolio's average maturity(9) target to a
65- to 70-day range. We have extended the Portfolio's average maturity by buying
what we deem to be high quality liquid municipal notes.

The Portfolio's increased average maturity reflects:

     - A slowdown in economic activity over the near-term; and
     - Less supply of high quality short-term municipal paper.

The record expansion of the U.S. economy has produced budget surpluses for many
state and local governments, which in turn, has decreased the need for
short-term cash flow financing.

Thank you for investment in the Smith Barney Muni Funds - California Money
Market Portfolio. We look forward to continuing to help you pursue your
financial goals in the future.

Sincerely,

/s/ Joseph P. Deane               /s/ Joseph Benevento

BOND RATINGS (UNAUDITED)
--------------------------------------------------------------------------------
The definitions of the applicable rating symbols are set forth below.

STANDARD & POOR'S RATINGS SERVICE ("STANDARD & POOR'S") -- "AA" ratings may be
modified by the addition of a plus (+) or minus (-) sign to show relative
standings within the major rating categories.

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 differ from the highest rated issue only in a
            small degree.

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") -- Numerical modifiers 1, 2, and 3
may be applied to each "Aa" rating, where 1 is the highest and 3 the lowest
rating within its generic category.

Aaa      -- Bonds rated "Aaa" by Moody's 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 these bonds.

Aa       -- Bonds 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.

--------------------------------------------------------------------------------
SHORT-TERM SECURITIES RATINGS (UNAUDITED)
--------------------------------------------------------------------------------
SP-1     -- Standard & Poor's highest rating indicating very strong or strong
            capacity to pay principal and interest; those issues determined to
            possess overwhelming safety characteristics are denoted with a plus
            (+) sign.

A-1      -- Standard & Poor's highest commercial paper and variable-rate demand
            obligation (VRDO) rating indicating that the degree of safety
            regarding timely payment is either overwhelming or very strong;
            those issues determined to possess overwhelming safety
            characteristics are denoted with a plus (+) sign.

VMIG 1 -- Moody's highest rating for issues having a demand feature -- VRDO.

MIG 1  -- Moody's highest rating for short-term municipal obligations.

P-1    -- Moody's highest rating for commercial paper and for VRDO prior to the
          advent of the VMIG 1 rating.

NR     -- Indicates that the bond is not rated by either Standard & Poor's or
          Moody's.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

The California Money Market Portfolio ("Portfolio") is a separate investment
portfolio of the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company and consists of this
Portfolio and eight other separate investment portfolios: Florida, Georgia,
Limited Term, New York, National, Pennsylvania, Massachusetts Money Market and
New York Money Market Portfolios. The financial statements and financial
highlights for the other portfolios are presented in separate shareholder
reports.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) the Portfolio uses
the amortized cost method for valuing investments; accordingly, the cost of
securities plus accreted discount, or minus amortized premium, approximates
value; (c) gains or losses on the sale of securities are calculated by using the
specific identification method; (d) interest income, adjusted for amortization
of premium and accretion of original issue discount, is recorded on accrual
basis; market discount is recognized upon the disposition of the security; (e)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (f) direct expenses are charged to each portfolio and each class;
management fees and general fund expenses are allocated on the basis of relative
net assets; (g) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles; (h) the Portfolio 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.  PORTFOLIO CONCENTRATION

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

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
--------------------------------------------------------------------------------
3. EXEMPT-INTEREST DIVIDENDS AND OTHER DISTRIBUTIONS

The Portfolio declares and records a dividend of substantially all its net
investment income on each business day. Such dividends are paid or reinvested
monthly in fund shares on the payable date. Furthermore, the Portfolio intends
to satisfy conditions that will enable interest from municipal securities, which
is exempt from regular Federal income tax and from designated state income
taxes, to retain such tax-exempt status when distributed to the shareholders of
the Portfolio.

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

4. MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS

SSB Citi Fund Management LLC ("SSBC"), a subsidiary of Salomon Smith Barney
Holdings Inc. ("SSBH") which, in turn, is a subsidiary of Citigroup Inc.
("Citigroup"), acts as investment manager to the Fund. The Portfolio pays SSBC a
management fee calculated at an annual rate of 0.50% on the first $2.5 billion
of average daily net assets; 0.475% on the next $2.5 billion and 0.45% on the
average daily net assets in excess of $5 billion. This fee is calculated daily
and paid monthly.

Citi Fiduciary Trust Company ("CFTC"), another subsidiary of Citigroup, acts as
the Fund's transfer agent and PFPC Global Fund Services ("PFPC") became the
Fund's sub-transfer agent. CFTC receives account fees and asset-based fees that
vary according to the size and type of account. PFPC is responsible for
shareholder recordkeeping and financial processing for all shareholder accounts
and is paid by CFTC. During the six months ended September 30, 2000, the
Portfolio paid transfer agent fees of $223,267 to CFTC.

Effective June 5, 2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of
SSBH, became the Fund's distributor replacing CFBDS, Inc. ("CFBDS"). In
addition, SSB acts as the primary broker for the Fund's portfolio agency
transactions. Certain other broker-dealers continue to sell Portfolio shares to
the public as members of the selling group.

Pursuant to a Distribution Plan, the Portfolio pays a distribution fee with
respect to Class A shares calculated at the annual rate of 0.10% of the average
daily net assets of that class.

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

5. CAPITAL LOSS CARRYFORWARDS

At March 31, 2000, the Portfolio had, for Federal income tax purposes, a capital
loss carryforward of approximately $50,600 available to offset future capital
gains. To the extent that these carryforward losses are used to offset capital
gains, it is probable that any gains so offset will not be distributed. The
amount and expiration of the carryforwards are indicated below. Expiration
occurs on March 31, of the year indicated:


                                                        2004            2008
