JAY GERKEN, CFA Chairman, President and Chief Executive Officer Dear Shareholder, Amid uneven prospects about the economy, stock market volatility and geopolitical concerns during the past year, many investors shifted their hard-earned dollars into shorter-term fixed-income funds to complement their higher-risk investments. During much of the year, interest rate concerns remained contained due to lackluster employment data, subdued inflation and comments from the Fed, which led many investors to believe that it would refrain from raising its interest rate targets. However, the U.S. economy picked up over the period, and national job growth for March significantly exceeded estimates.(i) Throughout the year the fund's manager anticipated that economic growth on a national basis could improve, and a pick-up in activity, which could potentially lead to higher inflation and interest rates. Therefore, the manager maintained a relatively defensive posture in managing the portfolio's exposure to inflation and interest rate risk by maintaining a relatively neutral average maturity. Municipal money market securities provide income that is exempt from federal, and sometimes state and local, income taxes. Your financial adviser can help you implement a suitable asset allocation based on your investment profile to help you pursue your long-term financial goals. Please read on for a more detailed look at prevailing economic and market conditions during the fund's fiscal year and to learn how those conditions and changes made to the portfolio during this time may have affected fund performance. Information About Your Fund In recent months several issues in the mutual fund industry have come under the scrutiny of federal and state regulators. The fund's Adviser and some of its affiliates have received requests for information from various government regulators regarding market timing, late trading, fees and other mutual fund issues in connection with various investigations. The regulators appear to be examining, among other things, the fund's response to market timing and shareholder exchange activity, including compliance with prospectus disclosure 1 Smith Barney Muni Funds | 2004 Annual Report related to these subjects. The fund has been informed that the Adviser and its affiliates are responding to those information requests, but are not in a position to predict the outcome of these requests and investigations. As always thank you for your confidence in our stewardship of your assets. We look forward to helping you continue to meet your financial goals. Sincerely, /s/ R. Jay Gerken R.

DEANE JULIE P. CALLAHAN, CFA Vice President and Vice President and Investment Officer Investment Officer Performance Review As of March 31, 2004, the seven-day current yield for Class A shares of the Smith Barney Muni Funds--Massachusetts Money Market Portfolio was 0.42% and its seven-day effective yield, which reflects compounding, was 0.42%. These numbers are the same due to rounding. The seven-day effective yield is calculated similarly - -------------------------------------------------------------------------------- SMITH BARNEY MUNI FUNDS--MASSACHUSETTS MONEY MARKET PORTFOLIO YIELDS AS OF MARCH 31, 2004 - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Seven-day current yield 0.42% - -------------------------------------------------------------------------------- Seven-day effective yield 0.42% - -------------------------------------------------------------------------------- The performance shown represents past performance. Past performance is no guarantee of future results and current performance may be higher or lower than the performance shown above. Principal value and investment returns will fluctuate and investors' shares, when redeemed may be worth more or less than their original cost. The fund's yields will vary and performance of other share classes may differ. Please note that your investment is neither insured nor guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. In the cases where the current yield and effective yield are the same, it is due to rounding. The seven-day current yield reflects the amount of income generated by the investment during that seven-day period and assumes that the income is generated each week over a 365-day period. The yield is shown as a percentage of the investment. The seven-day effective yield is calculated similarly to the seven-day current yield but, when annualized, the income earned by an investment in the fund is assumed to be reinvested. The effective yield typically will be slightly higher than the current yield because of the compounding effect of the assumed reinvestment. Certain investors may be subject to the federal Alternative Minimum Tax, and state and local taxes may apply. Capital gains, if any, are fully taxable. Please consult your personal tax adviser. - -------------------------------------------------------------------------------- 3 Smith Barney Muni Funds | 2004 Annual Report to the seven-day current yield but, when annualized, the income earned by an investment in the fund is assumed to be reinvested.

Market Overview In order to help boost economic activity, last June the Fed reduced its target for the federal funds rate,(ii) which dropped to four-decade lows. As a result, the yields on tax-exempt money market instruments continued to fall. By August, evidence of an improvement in the national economy emerged, and as a result longer-term bond yields started to rise. However, many investors believed the Fed would likely leave short-term interest rates at prevailing low levels over the foreseeable future, and tax-exempt money market yields generally remained near their lows. Stronger-than-anticipated economic growth consensus estimates for the third calendar quarter rekindled concerns about interest rates and inflation. Despite the 8.2% annual growth in gross domestic product ("GDP")(iii) over the third quarter of 2003, investors' concerns about the prospects of inflation and rising rates were contained because some of this growth was attributable to one-time factors, such as the tax cuts and the end of major combat operations in Iraq. Furthermore, many investors felt the Fed appeared to be in a holding pattern from adjusting its rate targets. Investors Question the Fed's Patience Investors spent the first quarter of 2004 dissecting language from the Fed, which stated in late January that it "believes that it can be patient in removing its policy accommodation."(iv) However, the fact that the Fed did not include the phrase "considerable period" in this statement as it had before, led many investors to question when the Fed's patience would run out. 4 Smith Barney Muni Funds | 2004 Annual Report Estimates of calendar fourth-quarter 2003 GDP annual growth released during the period registered at 4.1%.(iii) This rate was below third-quarter 2003 results but exceeded levels from early last year. Furthermore, in recent testimony to Congress, Fed Chairman, Alan Greenspan revealed that the Fed raised its expectations for economic growth. Although the economy has shown significant signs of improvement since early last year, the job market has remained the weak link to a sustainable recovery. Employment data(v) released after the first quarter of 2004 ended showed that the unemployment rose to 5.7% in March, versus 5.6% in February. However, the U.S. economy added 308,000 non-farm payroll jobs in March,(v) marking the largest number since April 2000.(vi) This result raised expectations that the strength of the economy may be improving, raising concerns that inflation could pick up and interest rates rise sooner than previously anticipated. Massachusetts' Economy(vii) The Governor-proposed $23 billion fiscal 2005 budget, which was introduced to the Massachusetts legislature in late January, eliminates a potential $1.5 billion budget gap without raising taxes or using existing reserve funds. The budget does not rely upon a full economic recovery to maintain balance, and it has a focus on managing costs. The revenue estimate builds in a modest economic recovery. Standard & Poor's recent rating on the state's longer-term bond obligations was AA+ with a stable outlook. Investment Approach The fund included a significant amount of municipal obligations backed by school districts and revenue bonds. Revenue bonds are issued to finance public works such as tunnels, sewer systems and bridges, and are supported directly by the revenues derived from the operations of these systems. The fund maintained a diversified mix of securities that included tax-exempt commercial paper, fixed-rate notes and variable-rate demand obligations. During the year we reduced the average maturity of the fund to 29 days. This was a reflection of the belief that the short-term municipal yield curve was very flat and there was no added benefit from purchasing securities with longer maturities. 5 Smith Barney Muni Funds | 2004 Annual Report Thank you for your investment in the Smith Barney Muni Funds--Massachusetts Money Market Portfolio.

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 ("Moody's") -- Numerical modifiers 1, 2 and 3 may be applied to generic rating "Aa", 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 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. ================================================================================ 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. VMIG 1 -- Moody's highest rating for issues having a demand feature -- VRDO. MIG 1 -- Moody's highest rate for short-term municipal obligations.

Significant Accounting Policies The Massachusetts Money Market Portfolio ("Fund"), a separate investment fund of the Smith Barney Muni Funds ("Trust"), a Massachusetts business trust, is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The Trust consists of this Fund and eight other separate investment funds: Florida, Georgia, Limited Term, National, New York, Pennsylvania, California Money Market and New York Money Market Portfolios. The financial statements and financial highlights for the other funds are presented in separate shareholder reports. The following are significant accounting policies consistently followed by the Fund and are in conformity with generally accepted accounting principles ("GAAP"): (a) security transactions are accounted for on trade date; (b) the Fund 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 discount, is recorded on an accrual basis; (e) dividends and distributions to shareholders are recorded on ex-dividend date; (f) the Fund intends to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies and to make distributions of taxable income sufficient to relieve it from substantially all Federal income and excise taxes; (g) the character of income and gains to be distributed is determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America; and (h) estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. 2. Fund Concentration Since the Fund invests primarily in obligations of issuers within Massachusetts, it is subject to possible concentration risks associated with economic, political, or legal developments or industrial or regional matters specifically affecting Massachusetts. 16 Smith Barney Muni Funds | 2004 Annual Report ================================================================================ Notes to Financial Statements (continued) ================================================================================ 3. Exempt-Interest Dividends and Other Distributions The Fund 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 Fund 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 Fund. Capital gain distributions, if any, are taxable to shareholders, and are declared and paid at least annually. 4. Management Agreement and Other Transactions Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), acts as investment manager to the Fund. Effective July 1, 2003, the Fund pays SBFM a management fee calculated at an annual rate of 0.475% on the first $1 billion of the Fund's average daily net assets; 0.450% on the next $1 billion; 0.425% on the next $3 billion; 0.400% on the next $5 billion and 0.375% on the Fund's average daily net assets in excess of $10 billion. This fee is calculated daily and paid monthly. Prior to July 1, 2003, the Fund paid SBFM a management fee calculated at an annual rate of 0.500% on the first $2.5 billion of the Fund's average daily net assets; 0.475% on the next $2.5 billion and 0.450% on the Fund's average daily net assets in excess of $5 billion. This fee was calculated daily and paid monthly. Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the Fund's transfer agent. PFPC Inc. ("PFPC") acts as the Fund's sub-transfer agent. CTB 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 CTB. For the year ended March 31, 2004, the Fund paid transfer agent fees of $39,132 to CTB. Citigroup Global Markets Inc. ("CGM"), another indirect wholly-owned subsidiary of Citigroup, acts as the Fund's distributor. Pursuant to a Rule 12b-1 Distribution Plan, the Fund pays a distribution fee with respect to its Class A shares calculated at the annual rate of 0.10% of the average 17 Smith Barney Muni Funds | 2004 Annual Report ================================================================================ Notes to Financial Statements (continued) ================================================================================ daily net assets of that class. For the year ended March 31, 2004, total Rule 12b-1 Distribution Plan fees, which are accrued daily and paid monthly, were $269,617. All officers and one Trustee of the Trust are employees of Citigroup or its affiliates. 5. Shares of Beneficial Interest At March 31, 2004, the Trust had an unlimited amount of shares of beneficial interest authorized with a par value of $0.001 per share. Transactions in shares of the Fund were as follows: Year Ended Year Ended March 31, 2004 March 31, 2003 ================================================================================ Class A Shares sold 1,122,099,513 950,510,458 Shares issued on reinvestment 1,160,548 2,195,084 Shares reacquired (1,154,786,703) (998,623,569) - -------------------------------------------------------------------------------- Net Decrease (31,526,642) (45,918,027) ================================================================================ 6. Income Tax Information and Distribution to Shareholders At March 31, 2004, the tax basis components of distributable earnings were: ================================================================================ Undistributed tax-exempt income $43,029 ================================================================================ The tax character of distributions paid during the year ended March 31 was: 2004 2003 ================================================================================ Tax-exempt income $1,164,804 $2,113,825 ================================================================================ 7. Additional Information The Fund has received the following information from Citigroup Asset Management ("CAM"), the Citigroup business unit which includes the Fund's Investment Manager and other investment advisory companies, all of which are indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an affiliate, into the transfer agent business in the period 1997-1999. As CAM currently understands the facts, at the time CAM decided to enter the transfer agent business, CAM sub-contracted for a period of five years certain of the transfer agency services to a third party and also concluded a revenue guarantee agreement with this sub-contractor providing that the sub-contractor would 18 Smith Barney Muni Funds | 2004 Annual Report ================================================================================ Notes to Financial Statements (continued) ================================================================================ guarantee certain benefits to CAM or its affiliates (the "Revenue Guarantee Agreement"). In connection with the subsequent purchase of the sub-contractor's business by an affiliate of the current sub-transfer agent (PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee Agreement was amended eliminating those benefits in exchange for arrangements that included a one-time payment from the sub-contractor. The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue Guarantee Agreement with the sub-contractor at the time the Boards considered and approved the transfer agent arrangements. Nor were the Boards informed of the subsequent amendment to the Revenue Guarantee Agreement when that occurred. CAM has begun to take corrective actions. CAM will pay to the applicable funds approximately $17 million (plus interest) that CAM and its affiliates received from the Revenue Guarantee Agreement and its amendment. CAM also plans an independent review to verify that the transfer agency fees charged by CAM were fairly priced as compared to competitive alternatives. CAM is instituting new procedures and making changes designed to ensure no similar arrangements are entered into in the future. CAM has briefed the SEC, the New York State Attorney General and other regulators with respect to this matter, as well as the U.S. Attorney who is investigating the matter. CAM is cooperating with governmental authorities on this matter, the ultimate outcome of which is not yet determinable. 19 Smith Barney Muni Funds | 2004 Annual Report ================================================================================ Financial Highlights ================================================================================ For a share of beneficial interest outstanding throughout each year ended March 31, unless otherwise noted: Class A Shares 2004 2003 2002 2001 2000(1) ========================================================================================================== Net Asset Value, Beginning of Year $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 - ---------------------------------------------------------------------------------------------------------- Net investment income(2) 0.004 0.008 0.018 0.034 0.016 Dividends from net investment income (0.004) (0.008) (0.018) (0.034) (0.016) - ---------------------------------------------------------------------------------------------------------- Net Asset Value, End of Year $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 - ---------------------------------------------------------------------------------------------------------- Total Return(3) 0.44% 0.78% 1.81% 3.46% 1.66%++ - ---------------------------------------------------------------------------------------------------------- Net Assets, End of Year (millions) $ 223 $ 254 $ 300 $ 336 $ 260 - ---------------------------------------------------------------------------------------------------------- Ratios to Average Net Assets: Expenses(2)(4) 0.61% 0.65% 0.65% 0.65% 0.65%+ Net investment income 0.43 0.78 1.80 3.36 3.05+ ========================================================================================================== (1) For the period September 14, 1999 (commencement of operations) to March 31, 2000. (2) The manager waived a portion of its fees for the years ended March 31, 2002, March 31, 2001, and the period ended March 31, 2000. If such fees were not waived, the per share decreases to net investment income and the actual expense ratios would have been as follows: Per Share Decreases to Expense Ratios Net Investment Income Without Fee Waiver ---------------------- ------------------ 2002 $0.000* 0.66% 2001 0.000* 0.66 2000 0.001 0.76+ (3) Performance figures may reflect fee waivers and/or expense reimbursements. Past performance is no guarantee of future results. In the absence of fee waivers and/or expense reimbursements, the total return would be reduced. (4) As a result of voluntary expense limitations, the ratio of expenses to average net assets will not exceed 0.80%. * Amount represents less than $0.001 per share. ++ Total return is not annualized, as it may not be representative of the total return for the year. + Annualized. 20 Smith Barney Muni Funds | 2004 Annual Report ================================================================================ Independent Auditors' Report ================================================================================ To the Shareholders and Board of Trustees of Smith Barney Muni Funds: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Massachusetts Money Market Portfolio ("Fund") of the Smith Barney Muni Funds ("Trust") as of March 31, 2004, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended and the financial highlights for each of the years in the four-year period then ended and for the period from September 14, 1999 (commencement of operations) to March 31, 2000. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2004, by correspondence with the custodian. As to securities sold but not yet delivered, we performed other appropiate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Fund as of March 31, 2004, and the results of its operations for the year then ended, and the changes in its net assets for each of the years in the two-year period then ended, and its financial highlights for each the years in the four-year period then ended and for the period from September 14, 1999 to March 31, 2000, in conformity with accounting principles generally accepted in the United States of America. /s/ KPMP LLP New York, New York May 12, 2004 21 Smith Barney Muni Funds | 2004 Annual Report ================================================================================ Additional Information (unaudited) ================================================================================ Information about Trustees and Officers The business and affairs of the Massachusetts Money Market Portfolio ("Fund") are managed under the direction of the Smith Barney Muni Funds' ("Trust") Board of Trustees.

Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible. Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund ("Covered Service Providers") constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit. (f) N/A (g) Non-audit fees billed - $100,000 and $1.2 million for the years ended 12/31/2003 and 12/31/2002. (h) Yes. The Smith Barney Muni Funds' Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates which were not pre-approved (not requiring pre-approval) is compatible with maintaining the Accountant's independence. All services provided by the Accountant to the Smith Barney Muni Funds or to Service Affiliates which were required to be pre-approved were pre-approved as required. ITEM 5.
