LETTER  FROM  THE  CHAIRMAN

R. JAY GERKEN, CFA

Chairman, President and Chief Executive Officer

Dear Shareholder,

Despite rising interest rates, continued high oil prices, geopolitical concerns and uncertainties surrounding the U.S. Presidential election, the U.S. economy continued to expand during the period. Following a 3.3% gain in the second quarter of 2004, gross domestic product (“GDP”)ⁱ growth was a robust 4.0% in the third quarter and 3.8% in the fourth quarter. On April 28, after the reporting period ended, first quarter 2005 GDP growth estimate came in at 3.1%.

Given the overall strength of the economy, Federal Reserve Board (“Fed”)ⁱⁱ moved to raise interest rates in an attempt to ward off inflation. As expected, the Fed increased its target for the federal funds rateⁱⁱⁱ by 0.25% to 1.25% on June 30, 2004 — the first rate hike in four years. The Fed again raised rates in 0.25% increments during its next six meetings, bringing the target for the federal funds rate to 2.75% by the end of March. The Fed raised its target rate by an additional 0.25% to 3.00% at its May meeting, after the Fund’s reporting period.

For much of the reporting period, the fixed-income market confounded many investors as short-term interest rates rose in concert with the Fed rate tightening, while longer-term rates, surprisingly, remained fairly steady. However, this changed late in the period, coinciding with the Fed’s official statement accompanying its March rate hike. While the Fed continued to say it expected to raise rates at a “measured” pace, it made several adjustments to its statement, which many investors interpreted to mean larger rate hikes could be possible in the future.

The municipal bond market, represented by the Lehman Brothers Municipal Bond Index,^iv rose 2.67% for the year. Like the other fixed-income markets, longer maturity munis performed better than their shorter-term counterparts.

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 have affected Fund performance.

Information About Your Fund

As you may be aware, several issues in the mutual fund industry have recently 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 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.

Important information concerning the Fund and its Adviser with regard to recent regulatory developments is contained in the “Additional Information” note in the Notes to the Financial Statements included in this report.

MANAGER  OVERVIEW

Although labor market growth^v languished throughout 2003 into the first quarter of 2004, it rose significantly and remained strong in the early spring, and inflation picked up as well.^vi

After an extended period of monetary easing, the Fed’s monetary policymaking committee^vii raised its federal funds rate target from a four-decade low of 1.00% to 1.25% at the end of June — the Fed’s first hike in four years. The increase marked a significant reversal from the Fed’s monetary policy position from June 2003, when it last slashed its rate target following a long series of accommodative rate cuts. The rate hike was widely anticipated due to comments from the Fed regarding the momentum behind the economy and signals that it was prepared to push rates higher from their near-historic lows. As a result, bond prices declined and yields rose sharply in April before prices stabilized somewhat in the early summer.

The Fed once again raised its federal funds target by 0.25% in August and September, bringing the rate to 1.75%. Given that bond prices had already factored in rate hikes to a significant extent, and coupling this with a lack of inflationary pressures, bond prices held up and actually rose over the third quarter. In September and October, the bond market benefited from falling stock and rising oil prices, which encouraged investors to reallocate capital into fixed-income securities.

Yields on bonds rose as their prices dropped in reaction to an employment report issued in November that yielded surprisingly robust labor market results.^v The Fed subsequently raised its federal funds rate target by 25 basis points^viii at its meetings in November, December, February and March, bringing the rate target to 2.75% at the end of the reporting period. The Fed raised its target rate by an additional 0.25% to 3.00% at its May meeting, after the Fund’s reporting period.

Regardless of the economic expansion and higher interest rates, the overall bond market posted a modest gain during the period. Municipal bond credit quality continued to improve, as municipalities benefited from higher tax revenues, driven by improving economic growth and fiscal discipline. This caused municipal credit quality spreads to tighten.

Over the 12-month period, municipal bonds outperformed maturity equivalent U.S. Treasuries.^ix Compelling taxable equivalent yields^x for investors in

PERFORMANCE SNAPSHOT

AS OF MARCH 31, 2005

(excluding sales charges)

(unaudited)

	6 Months		12 Months
National Portfolio — Class A Shares	2.68	%	4.57	%
Lehman Brothers Municipal Bond Index	1.21	%	2.67	%
Lipper General Municipal Debt Funds Category Average	0.91	%	2.03	%

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. To obtain performance data current to the most recent month-end, please visit our website at www.citigroupam.com.

Performance figures may reflect reimbursements and/or fee waivers, without which the performance would have been lower.

Class A share returns assume the reinvestment of income dividends and capital gains distributions at net asset value and the deduction of all fund expenses. Returns have not been adjusted to include sales charges that may apply when shares are purchased or the deduction of taxes that a shareholder would pay on fund distributions. Excluding sales charges, Class B shares returned 2.42% and Class C shares returned 2.45% over the six months ended March 31, 2005. Excluding sales charges, Class B shares returned 4.12% and Class C shares returned 4.03% over the 12 months ended March 31, 2005.

Lipper, Inc. is a major independent mutual-fund tracking organization. Returns are based on the period ended March 31, 2005, including the reinvestment of dividends and capital gains distributions, if any, calculated among the 289 funds for the six-month period and among the 284 funds for the 12-month period in the Fund’s Lipper category and excluding sales charges.

middle- and higher- federal income tax brackets and low default rates continued to attract investors to municipal bond funds.

Performance Review

For the 12 months ended March 31, 2005, Class A shares of the Smith Barney Muni Funds — National Portfolio, excluding sales charges, returned 4.57%. These shares outperformed the Lipper General Municipal Debt Funds Category Average,¹ which was 2.03%. The Fund’s unmanaged benchmark, the Lehman Brothers Municipal Bond Index, returned 2.67% for the same period.

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 or legal adviser.

Factors that Influenced Fund Performance

Over the period, the Fund’s toll road and hospital issues were among the strongest performers. In addition, various corporate-backed and tobacco related securities contributed positively to results as market perceptions of credit quality improved.

Conversely, our positioning strategy in long-term Treasury futures detracted from performance. While we believe strategy reduced the portfolio’s overall volatility and may have helped to offset price declines when yields rose sharply from April through mid-June, overall it was a drag on performance during the reporting period. In addition, the Fund’s multi-family and student housing issues detracted from performance. Other detractors included special facility bonds for airlines in the transportation sector, hotel development and lifecare issues. A number of the Fund’s higher coupon securities were called at their first permissible opportunity, thus eroding some of the income the portfolio generates. Finally, our escrowed to maturity and pre-refunded issues, as well as other premium bonds with short calls, experienced modest price declines and also detracted from performance.

We have begun to pare some of our medium and lower grade holdings where risk elements are beginning to outweigh our assessment of reward potential as credit quality spreads have continued to narrow.

During the period we maintained a conservative posture in terms of overall duration,^xi or price sensitivity to interest rate movements. This low-duration approach to managing interest rate risk limited the Fund’s ability to completely participate in upside market movements during intervals when bond prices rose, such as last summer. However, the Fund benefited from this approach in absolute terms when bond prices dropped, particularly in the spring and fall. Given the current market environment, we believe this approach to reducing potential volatility is more prudent than a longer-duration strategy.

Thank you for your investment in the Smith Barney Muni Funds — National Portfolio. As ever, we appreciate that you have chosen us to manage your assets and we remain focused on achieving the Fund’s investment goals.

Sincerely,

Peter M. Coffey

RISKS: Keep in mind, the Fund’s investments are subject to interest rate and credit risks. As interest rates rise, bond prices fall, reducing the value of the Fund’s share price. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance.

All index performance reflects no deduction for fees, expenses or taxes. Please note an investor cannot invest directly in an index.

Fund Expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, including front-end and back-end sales charges (loads) on purchase payments, reinvested dividends, or other distributions; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

This example is based on an investment of $1,000 invested on October 1, 2004 and held for the six months ended March 31, 2005.

Actual Expenses

The table below titled “Based on Actual Total Return” provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period”.

Based on Actual Total Return⁽¹⁾

	Actual Total Return Without Sales Charges(2)		Beginning Account Value		Ending Account Value		Annualized Expense Ratio		Expenses Paid During the Period(3)
Class A	2.68	%	$	1,000.00	$	1,026.80	0.67	%	$	3.39
Class B	2.42			1,000.00		1,024.20	1.18			5.96
Class C(4)	2.45			1,000.00		1,024.50	1.24			6.26

(1) For the six months ended March 31, 2005.

(2) 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 charge with respect to Class A shares or the applicable contingent deferred sales charges (“CDSC”) with respect to Class B and C shares. Total return is not annualized, as it may not be representative of the total return for the year. Performance figures may reflect voluntary fee waivers and/or expense reimbursements. Past performance is no guarantee of future results. In the absence of voluntary fee waivers and/or expense reimbursements, the total return would have been lower.

(3) Expenses (net of voluntary fee waiver) are equal to each Fund’s respective annualized expense ratio, multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 365.

(4) On April 29, 2004, Class L shares were renamed as Class C shares.

Fund Expenses (unaudited) (continued)

Hypothetical Example for Comparison Purposes

The table below titled “Based on Hypothetical Total Return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or back-end sales charges (loads). Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Based on Hypothetical Total Return⁽¹⁾

	Hypothetical Annualized Total Return		Beginning Account Value		Ending Account Value		Annualized Expense Ratio		Expenses Paid During the Period(2)
Class A	5.00	%	$	1,000.00	$	1,021.59	0.67	%	$	3.38

Class C(3)	5.00			1,000.00		1,018.75	1.24			6.24

(1) For the six months ended March 31, 2005.

(2) Expenses (net of voluntary fee waiver) are equal to each Fund’s respective annualized expense ratio, multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 365.

† Hypothetical illustration of $10,000 invested in Class A shares on March 31, 1995, assuming deduction of the 4.00% maximum initial sales charge at the time of investment and reinvestment of dividends and capital gains through March 31, 2005. 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 as a mutual fund. Please note that an investor cannot invest directly in an index. The Lipper General Municipal Debt Funds Average is composed of an average of the Fund’s peer group of 284 mutual funds investing in municipal securities as of March 31, 2005. The performance of the Fund’s other classes may be greater or less than the Class A shares’ performance indicated on this chart, depending on whether greater or lesser sales charges and fees were incurred by shareholders investing in the other classes.

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 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 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 for bonds in higher rated categories.
BB, B, CCC and CC	—   Bonds rated “BB”, “B”, “CCC” and “CC” are regarded, on balance, as predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. “BB” represents a lowest degree of speculation than “B”, “CCC” and “CC”, 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 (“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 to be 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.

21        Smith Barney Muni Funds      |      2005 Annual Report

Bond Ratings (unaudited) (continued)

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 desirable investments. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.
Caa	—   Bonds rated “Caa” are of poor standing. These issues may be in default, or present elements of danger may exist with respect to principal or interest.
Fitch Ratings (“Fitch”) — Ratings from “A” to “CCC” 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 have a low expectation of credit risk. The capacity for timely payment of financial commitments is considered to be strong, but may be more vulnerable to changes in economic conditions and circumstances than bonds with higher ratings.
BBB	—   Bonds rated “BBB” 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.
BB	—   Bonds rated “BB” indicate that there is a possibility of credit risk developing, particularly as the result of adverse economic change over time; however, business of financial alternatives may be available to allow financial commitments to be met.
B	—   Bonds rated “B” indicate that significant credit risk is present, but a limited margin of safety remains. Financial Commitments are currently being met; however, capacity for continued payment is contingent upon a sustained, favorable business and economic environment.
CCC, CC and C	—   Bonds rated “CCC”, “CC” and “C” carry the real possibility of defaulting. The capacity to meet financial commitments depends solely on a sustained, favorable business and economic environment. Default of some kind on bonds rated “CC” appears probable, a “C” rating indicates imminent default.
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 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.

Per share information, ratios and supplemental data for the periods prior to April 1, 2001 have not been restated to reflect this change in presentation.

(4) Performance figures may reflect voluntary fee waivers and/or expense reimbursements. Past performance is no guarantee of future results. In the absence of voluntary fee waivers and/or expense reimbursements, the total return would have been lower.

(6) The investment manager voluntarily waived a portion of its fee for the year ended March 31, 2005. If such fees were not voluntarily waived, the actual expense ratio for Class C shares would have been 1.24%.

Notes to Financial Statements

1. Organization and Significant Accounting Policies

The National Portfolio (“Fund”), a separate diversified 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 following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements were prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ.

(a) Investment Valuation. Securities are valued at the mean between the bid and asked 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. Securities for which market quotations are not readily available or where market quotations are determined not to reflect fair value, will be valued in good faith by or under the direction of the Fund’s Board of Trustees. Short-term obligations with maturities of 60 days or less are valued at amortized cost, which approximates value.

(b) Financial Futures Contracts. The Fund may enter into futures contracts to the extent permitted by its investment policies and objectives. Upon entering into a futures contract, the Fund is required to deposit cash or securities as initial margin. Additional securities are also segregated up to the current market value of the futures contracts. Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying financial instrument, are made or received by the Fund each day (daily variation margin) and are recorded as unrealized gains or losses until the contracts are closed. When the contracts are closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transactions and the Fund’s basis in the contracts. The Fund enters into such contracts typically to hedge a portion of the portfolio. The risks associated with entering into futures contracts include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying financial instruments. In addition, investing in futures contracts involves the risk that the Fund could lose more than the original margin deposit and subsequent payments required for a futures transaction.

(c) Security Transactions and Investment Income. Security transactions are accounted for on a trade date basis. Interest income, adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. The cost of investments sold is determined by use of the specific identification method.

(d) Distributions to Shareholders. Dividends from net investment income for the Fund, if any, are declared and paid on a monthly basis. The Fund 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 Fund. Distributions of net realized gains to shareholders of the Fund, if any, are taxable and are declared at least annually. Dividends and distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(e) Class Accounting. Investment income, common expenses and realized/unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Distribution, transfer agency services and shareholder communications fees relating to a specific class are charged directly to that class.

(f) Federal and Other Taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute substantially all of its taxable income and net realized gains on investments, if any, to shareholders each year. Therefore, no federal tax provision is required.

29        Smith Barney Muni Funds      |      2005 Annual Report

Notes to Financial Statements (continued)

(g) Reclassifications. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. During the year ended March 31, 2005, the following reclassifications have been made:

Undistributed Net Investment Income	Accumulated Net Realized Loss
$(515,137)	$	515,137

These reclassifications are primarily due to differences between book and tax accretion of market discount on fixed income securities.

2. Management Agreement and Other Transactions with Affiliates

Smith Barney Fund Management LLC (“SBFM”), an indirect wholly-owned subsidiary of Citigroup Inc. (“Citigroup”), acts as investment manager to the Fund. The Fund pays SBFM a management fee calculated at the annual rate of 0.45% of the Fund’s average daily net assets. This fee is calculated daily and paid monthly.

During the year ended March 31, 2005, SBFM reimbursed the Fund in the amount of $100,000 for losses incurred from an investment transaction error.

During the year ended March 31, 2005, SBFM waived a portion of its management fee amounting to $31,896.

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, 2005, the Fund paid transfer agent fees of $76,088 to CTB.

Citigroup Global Markets Inc. (“CGM”), another indirect wholly-owned subsidiary of Citigroup, acts as the Fund’s distributor.

Effective April 29, 2004, Class L shares were renamed Class C Shares.

There is a maximum sales charge of 4.00% for Class A shares. 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 payment. This CDSC declines by 0.50% the first year after purchase payment and thereafter by 1.00% per year until no CDSC is incurred. Class C shares have a 1.00% CDSC, which applies if redemption occurs within one year from purchase payment. In certain cases, Class A shares have a 1.00% CDSC, which applies if redemption occurs within one year from purchase payment. 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 year ended March 31, 2005, CGM received sales charges of approximately $286,000 on sales of the Fund’s Class A shares. In addition, for the year ended March 31, 2005, CDSCs paid to CGM were approximately:

	Class A		Class B		Class C
CDSCs	$	0*	$	80,000	$	1,000

* Amount represents less than $1,000.

All officers and one Trustee of the Trust are employees of Citigroup or its affiliates and do not receive compensation from the Trust.

4. Class Specific Expenses

Pursuant to a Rule 12b-1 Distribution Plan (the “Plan”), the Fund pays a service fee with respect to its Class A, B and C shares calculated at the annual rate of 0.15% of the average daily net assets of each respective class. In addition, the Fund pays a distribution fee with respect to its Class B and C shares calculated at the annual rates of 0.50% and 0.55% of the average daily net assets of each class, respectively. For the year ended March 31, 2005, total Plan fees, which are accrued daily and paid monthly, were as follows:

The tax character of distributions paid during the fiscal years ended March 31, was as follows:

	2005		2004
Distributions paid from:
Tax Exempt Income	$	23,533,227	$	24,702,128
Ordinary Income		43,883		52,670

32        Smith Barney Muni Funds      |      2005 Annual Report

Notes to Financial Statements (continued)

(a) As of March 31, 2005, the Fund had the following net capital loss carryforwards remaining:

Year of Expiration	Amount
3/31/2008	$	(684,820	)
3/31/2009		(3,676,518	)
3/31/2012		(2,206,821	)
3/31/2013		(16,251,657	)
	$	(22,819,816	)

These amounts will be available to offset any future taxable capital gains.

(b) Other book/tax temporary differences are attributable primarily to the realization for tax purposes of unrealized gains on certain futures, the deferral of post-October capital losses for tax purposes and differences in the book/tax treatment of various items.

(c) The difference between book-basis and tax-basis unrealized appreciation/(depreciation) is attributable primarily to the tax deferral of losses on wash sales and the difference between book and tax accretion methods for market discount on fixed income securities.

8. Additional Information

Smith Barney Fund Management LLC (“SBFM”) and Citigroup Global Markets Inc. (“CGMI”) have submitted an Offer of Settlement of an administrative proceeding to the U.S. Securities and Exchange Commission (“SEC”) in connection with an investigation into the 1999 appointment of an affiliated transfer agent for the Smith Barney family of mutual funds (the “Funds”). SBFM and CGMI understand that the SEC has accepted the Offer of Settlement, but has not yet issued the administrative order.

The SEC order will find that SBFM and CGMI willfully violated Section 206(1) of the Investment Advisers Act of 1940 (“Advisers Act”). Specifically, the order will find that SBFM and CGMI knowingly or recklessly failed to disclose to the boards of the Funds in 1999 when proposing a new transfer agent arrangement with an affiliated transfer agent that: First Data Investors Services Group (“First Data”), the Funds’ then-existing transfer agent, had offered to continue as transfer agent and do the same work for substantially less money than before; and that Citigroup Asset Management (“CAM”) had entered into a side letter with First Data under which CAM agreed to recommend the appointment of First Data as sub-transfer agent to the affiliated transfer agent in exchange, among other things, for a guarantee by First Data of specified amounts of asset management and investment banking fees to CAM and CGMI. The order also will find that SBFM and CGMI willfully violated Section 206(2) of the Advisers Act by virtue of the omissions discussed above and other misrepresentations and omissions in the materials provided to the Funds’ boards, including the failure to make clear that the affiliated transfer agent would earn a high profit for performing limited functions while First Data continued to perform almost all of the transfer agent functions, and the suggestion that the proposed arrangement was in the Funds’ best interests and that no viable alternatives existed. SBFM and CGMI do not admit or deny any wrongdoing or liability. The settlement will not establish wrongdoing or liability for purposes of any other proceeding.

The SEC will censure SBFM and CGMI and order them to cease and desist from violations of Sections 206(1) and 206(2) of the Advisers Act. The order will require Citigroup to pay $208.1 million, including $109 million in disgorgement of profits, $19.1 million in interest, and a civil money penalty of $80 million. Approximately $24.4 million has already been paid to the Funds, primarily through fee waivers. The remaining $183.7 million, including the penalty, will be paid to the U.S. Treasury and then distributed pursuant to a plan to be prepared by Citigroup and submitted within 90 days of the entry of the order for approval by the SEC. The distribution plan may also include a portion of certain escrowed transfer agency fees, in accordance with the terms of the order.

The order will require SBFM to recommend a new transfer agent contract to the Fund boards within 180 days of the entry of the order; if a Citigroup affiliate submits a proposal to serve as transfer agent or sub-transfer agent, an independent monitor must be engaged at the expense of SBFM and CGMI to oversee a competitive bidding process. Under the order,

Notes to Financial Statements (continued)

Citigroup also will be required to comply with an amended version of a vendor policy that Citigroup instituted in August 2004. That policy, as amended, among other things, requires that when requested by a Fund board, CAM will retain at its own expense an independent consulting expert to advise and assist the board on the selection of certain service providers affiliated with Citigroup.

At this time, there is no certainty as to how the proceeds of the settlement will be distributed, to whom such distributions will be made, the methodology by which such distributions will be allocated, and when such distributions will be made. Although there can be no assurance, Citigroup does not believe that this matter will have a material adverse effect on the Funds.

9. Legal Matters

Beginning in June 2004, class action lawsuits alleging violations of the federal securities laws were filed against Citigroup Global Markets Inc. (the “Distributor”) and a number of its affiliates, including Smith Barney Fund Management LLC and Salomon Brothers Asset Management Inc (the “Advisers”), substantially all of the mutual funds managed by the Advisers, including the Fund (the “Funds”), and directors or trustees of the Funds (collectively, the “Defendants”). The complaints alleged, among other things, that the Distributor created various undisclosed incentives for its brokers to sell Smith Barney and Salomon Brothers funds. In addition, according to the complaints, the Advisers caused the Funds to pay excessive brokerage commissions to the Distributor for steering clients towards proprietary funds. The complaints also alleged that the defendants breached their fiduciary duty to the Funds by improperly charging Rule 12b-1 fees and by drawing on fund assets to make undisclosed payments of soft dollars and excessive brokerage commissions. The complaints also alleged that the Funds failed to adequately disclose certain of the allegedly wrongful conduct. The complaints sought injunctive relief and compensatory and punitive damages, rescission of the Funds’ contracts with the Advisers, recovery of all fees paid to the Advisers pursuant to such contracts and an award of attorneys’ fees and litigation expenses.

On December 15, 2004, a consolidated amended complaint (the “Complaint”) was filed alleging substantially similar causes of action. While the lawsuit is in its earliest stages, to the extent that the Complaint purports to state causes of action against the Funds, Citigroup Asset Management believes the Funds have significant defenses to such allegations, which the Funds intend to vigorously assert in responding to the Complaint.

Additional lawsuits arising out of these circumstances and presenting similar allegations and requests for relief may be filed against the Defendants in the future.

As of the date of this report, Citigroup Asset Management and the Funds believe that the resolution of the pending lawsuit will not have a material effect on the financial position or results of operations of the Funds or the ability of the Advisers and their affiliates to continue to render services to the Funds under their respective contracts.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of

Smith Barney Muni Funds:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of National Portfolio (“Fund”) of Smith Barney Muni Funds as of March 31, 2005, 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 five-year period then ended. 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 the standards of the Public Company Accounting Oversight Board (United States). 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, 2005, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 National Portfolio of Smith Barney Muni Funds as of March 31, 2005, and the results of its operations for the year then ended, the changes in its 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 five-year period then ended, in conformity with U.S. generally accepted accounting principles.

FOR PRINCIPAL EXECUTIVE AND

SENIOR FINANCIAL OFFICERS OF CAM/U.S. REGISTERED INVESTMENT

COMPANIES

I. Covered Officers/Purpose of the Code

This code of ethics (the “Code”) for Citigroup Asset Management’s (“CAM’s”) U.S. registered proprietary investment companies (collectively, “Funds” and each a, “Company”) applies to each Company’s Chief Executive Officer, Chief Administrative Officer, Chief Financial Officer and Controller (the “Covered Officers”) for the purpose of promoting:

• honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• full, fair, accurate, timely and understandable disclosure in reports and documents that the Company files with, or submits to, the Securities and Exchange Commission (“SEC”) and in other public communications made by the Company;

• compliance with applicable laws and governmental rules and regulations;

• the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

• accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

II. Administration of Code

The Regional Director of CAM Compliance, North America (“Compliance Officer”) is responsible for administration of this Code, including granting pre-approvals (see Section III below) and waivers (as described in Section VI below), applying this Code in specific situations in which questions are presented under it and interpreting this Code in any particular situation.

III. Covered Officers Should Ethically Handle Actual and Apparent Conflicts of Interest

Overview. A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the interests of, or his service to, the Company. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Company.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Company and already are subject to conflict of interest provisions in the Investment Company Act of 1940 (“Investment Company Act”) and the Investment Advisers Act of 1940 (“Investment Advisers Act”). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Company because of their status as “affiliated persons” of the Company. The compliance programs and procedures of the Company and its investment adviser are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code (see Section VII below).

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between a Company and the investment adviser of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for a Company or for the adviser, or for both), be involved in establishing policies and implementing decisions that will have different effects on the adviser and a Company. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Company and the adviser and is consistent with the performance by the Covered Officers of their duties as officers of a Company. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the Funds’ Boards of Directors\Trustees (“Boards”) that the Covered Officers may also be officers or employees of one or more other investment companies covered by this or other codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Company.

*                    *                     *                        *

Each Covered Officer must:

• not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting (e.g. through fraudulent accounting

                  practices) by the Company whereby the Covered Officer¹ would benefit personally to the detriment of the Company; or

• not cause the Company to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than for the benefit of the Company; and

• not use material non-public knowledge of portfolio transactions made or contemplated for the Company to trade personally or cause others to trade personally in contemplation of the market affect of such transactions.

• There are some potential conflict of interest situations that should always be discussed with the Compliance Officer, if material. Examples are as follows:

(1) service as a director on the board of any public or private company;

(2) any ownership interest in, or any consulting or employment relationship with, any of the Company’s service providers, other than its investment adviser,

(3) a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Company for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer’s employment, such as compensation or equity ownership; and

(4) the receipt of any gifts or the conveyance of any value (including entertainment ) from any company with which the Company has current or prospective business dealings, except:

(a) any non-cash gifts of nominal value (nominal value is less than $100); and

(b) customary and reasonable meals and entertainment at which the giver is present, such as the occasional business meal or sporting event.

IV. Disclosure and Compliance

Each Covered Officer:

• should be familiar with his or her responsibilities in connection with the disclosure requirements generally applicable to the Company;

¹ Any activity or relationship that would present a conflict for a Covered Officer would also present a conflict for the Covered Officer if a member of a Covered Officer’s family (spouse, minor children and any account over which a Covered Officer is deemed to have beneficial interest) engages in such an activity or has such a relationship.

• should not knowingly misrepresent, or knowingly cause others to misrepresent, facts about the Company to others, whether within or outside the Company, including to the Company’s directors and auditors, and to governmental regulators and self-regulatory organizations;

• should, to the extent appropriate within his or her area of responsibility, consult with other officers and employees of the Funds and the investment adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Funds file with, or submit to, the SEC and in other public communications made by the Funds; and

• is responsible to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

V. Reporting and Accountability

Each Covered Officer must:

• upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing to the Board that the Covered Officer has received, read, and understands the Code;

• annually thereafter affirm to the Board that he or she has complied with the requirements of the Code;

• annually disclose affiliations and other relationships related to conflicts of interest;

• not retaliate against any other Covered Officer or any employee of the Funds or their affiliated persons for reports of potential violations that are made in good faith; and

• notify the Compliance Officer promptly if he knows of any violation of this Code (failure to do so is itself a violation of this Code).

In rendering decisions and interpretations and in conducting investigations of potential violations under the Code, the Compliance Officer may, at his discretion, consult with such persons as he determines to be appropriate, including, but not limited to, a senior legal officer of the Company or its investment adviser or its affiliates, independent auditors or other consultants, subject to any requirement to seek pre-approval from the Company’s audit committee for the retention of independent auditors to perform permissible non-audit services. The Funds will follow these procedures in investigating and enforcing the Code:

• the Compliance Officer will take all appropriate action to investigate any potential violation of which he becomes aware;

• if, after investigation the Compliance Officer believes that no violation has occurred, the Compliance Officer is not required to take any further action;

• any matter that the Compliance Officer believes is a violation will be reported to the Directors of the Fund who are not “interested persons” as defined in the Investment Company Act the (“Non-interested Directors”)

• if the Non-interested Directors of the Board concur that a violation has occurred, it will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to dismiss the Covered Officer; and

• any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules

The Compliance Officer shall submit an annual report to the Board describing any waivers granted.

VI. Waivers²

A Covered Officer may request a waiver of any of the provisions of the Code by submitting a written request for such waiver to the Compliance Officer, setting forth the basis of such request and explaining how the waiver would be consistent with the standards of conduct described herein. The Compliance Officer shall review such request and make a determination thereon in writing, which shall be binding.

In determining whether to waive any provisions of this Code, the Compliance Officer shall consider whether the proposed waiver is consistent with honest and ethical conduct and other purposes of this Code.

VII. Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Funds, the Funds’ investment advisers, principal underwriters, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. The codes of ethics of the funds and the investment advisers and principal underwriters under Rule 17j-1 of the Investment Company Act and the Citigroup Code of Conduct and Citigroup Statement of Business Practices as well as other policies of the Fund’s investment advisers or their affiliates are separate requirements applying to the Covered Officers and others, and are not part of this Code.

² For purposes of this Code, Item 2 of Form N-CSR defines “waiver” as “the approval by a Company of a material departure from a provision of the Code” and includes an “implicit waiver,” which means a Company’s failure to take action within a reasonable period of time regarding a material departure from a provision of the Code that has been made known to an executive officer of the Company.

VIII. Amendments

Any amendments to this Code, other than amendments to Exhibits A, B and C must be approved or ratified by a majority vote of the Board, including a majority of Non-interested Directors.

IX. Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the appropriate Board and Company and their respective counsel, counsel to the non-Interested Directors or independent auditors or other consultants referred to in Section V above.

X. Internal Use

The Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Company, as to any fact, circumstance, or legal conclusion.
