LETTER  FROM  THE  CHAIRMAN

R. JAY GERKEN, CFA

Chairman, President and Chief Executive Officer

Dear Shareholder,

Over the past 12 months, the domestic economy continued to recover from the recession of the prior three years, although a number of factors combined to slow its progress. At the start of the fund’s fiscal year in November 2003, many of the geopolitical concerns that had previously been pressuring both the economy and the stock market had begun to ease.

The initial phase of the conflict in Iraq had concluded and new federal tax legislation provided significant near-term tax cuts for consumers, businesses and investors. Key interest rates continued to hover near record lows and a wave of home mortgage refinancing freed additional cash for homeowners. Improving job growth numbers late in 2003, sustained consumer spending and positive corporate earnings news all contributed to a broad stock market rally through the end of last year. During the third calendar quarter of 2003, economic growth as measured by real gross domestic product (“GDP”)ⁱ growth reached 7.40%, a high not seen in almost two decades.

As the new calendar year began, economic indicators grew increasingly mixed, adding to growing uncertainty for investors that helped keep the stock market trading in a limited range. GDP growth dropped to 4.20% for the fourth quarter of 2003 and has remained relatively steady. Estimated GDP growth for the third quarter of 2004 is 3.70%.ⁱⁱ In the spring and summer, monthly job growth figures fluctuated between net gains and losses but improved through the fall, while overall unemployment remained below the recent high of 6.30% set in June 2003.ⁱⁱⁱ The U.S. Consumer Confidence Index^iv rose significantly from November of 2003 through July, but has since declined through October, reflecting consumers’ growing concern about the rate of job growth and the outlook for the economy.

Crude oil prices rose to record highs over the past year, leading to a spike in energy costs that helped curb consumer spending and acted as a brake on the domestic economy overall. After a year of four-decade-low rates, the Federal Reserve Bank (“Fed”)^v changed its stance from easing to tightening and raised the federal funds rate^vi target three times to 1.75% in September. Following the end of the fund’s reporting period, at its November meeting, the Fed once again raised its target for the federal funds rate by 0.25% to 2.00%. Where the market had been concerned about the possibility of deflation at the start of the period, economic worries now center on the risks of inflation.

The past 12 months in the stock market saw small- and mid-capitalization stocks continue to generally outperform large-caps. The Russell 2000 Index,^vii a proxy for the small-cap market, returned 11.73% for the period and the S&P MidCap 400 Index^viii returned 11.04%, while the S&P 500 Index^ix and the Dow Jones Industrial Average,^x which represent large-cap and blue chip stocks respectively, returned 9.41% and 4.49% for the same period. Value-oriented stocks continued to outpace growth-oriented stocks: the S&P 500 Barra Value Index^xi returned 14.46% for the period versus 4.49% for the S&P Barra Growth Index.^xii

Foreign stock markets, as represented by the MSCI EAFE Index,^xiii which returned 18.84%, strongly outperformed the broad domestic market as represented by the Wilshire 5000 Index,^xiv which returned 9.99%. Despite fluctuations during the year, bonds collectively generated positive total returns as reflected by the performance of the Lehman Brothers Aggregate Bond Index,^xv which returned 5.53% over the past 12 months.

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.

In November 2003, Citigroup Asset Management (“CAM”) disclosed an investigation by the Securities and Exchange Commission (“SEC”) and the U.S. Attorney relating to CAM’s entry into the transfer agency business during 1997-1999. Citigroup has disclosed that the Staff of the SEC is considering recommending a civil injunctive action and/or an administrative proceeding against certain advisory and transfer agent entities affiliated with Citigroup, the former CEO of CAM, two former employees and a current employee of CAM, relating to the creation, operation and fees of its internal transfer agent unit that serves various CAM-managed funds. Citigroup is cooperating with the SEC and will seek to resolve this matter in discussion with the SEC Staff. Although there can be no assurance, Citigroup does not believe that this matter will have a material adverse effect on the fund.

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,

R. Jay Gerken, CFA

MANAGER  OVERVIEW

Special Shareholder Notice

Effective November 1, 2004, the Smith Barney Large Cap Core Fund was renamed Smith Barney Dividend Strategy Fund. Scott Glasser and Peter Hable will serve as portfolio co-managers for the fund. Mr. Glasser and Mr. Hable are investment officers of the manager and managing directors of Citigroup Global Markets Inc. (“CGM”), one of the fund’s distributors. The investment objective of the fund is to seek capital appreciation, principally through investments in dividend-paying stocks. The investment policy of the fund is to invest, under normal market conditions, at least 80% of assets in dividend-paying stocks. The fund is permitted to invest up to 20% of assets in other types of securities, including non-dividend paying companies, preferred stocks and fixed income securities. The fund’s manager has agreed to voluntarily reimburse certain fund expenses in order to cap the fund’s Class A expenses at 1.25% and Class B expenses at 2.00%. The manager may discontinue this reimbursement at any time.

Market Review

At the start of the 12-month period in November of 2003, the equity marketplace was enjoying a strong rally that showed many of the global equity markets recovering to levels not seen for months. For most of calendar year 2003 and through October of 2004, the equity marketplace was working off its multi-year low seen on October 9, 2002. Improving economic growth, as measured by gross domestic product (“GDP”)ⁱ growth for the third quarter of 2003, as well as better corporate performance, combined to produce strong equity performance in the fourth quarter of 2003 for most market sectors. Aggressive monetary and fiscal policies finally manifested themselves in the third calendar quarter of 2003 with 7.40% real domestic growth, the best that the U.S. has seen in almost two decades.

In March of 2004, signs of inflation began to show as seen by the GDP deflator^xvi at 2.50% (annualized), which was the highest inflation we have seen since June 2001. This level of inflation was due to higher energy costs working themselves through the system. We believe that the financial marketplace continues to discount a sustainable recovery albeit with higher levels of inflation and, as a result, more restrictive monetary policy.

Stocks were generally stuck in a limited trading range through much of the second quarter of 2004, as

PERFORMANCE SNAPSHOT

AS OF OCTOBER 31, 2004

(excluding sales charges)

	6 Months			12 Months
Class A Shares — Dividend Strategy Fund	-	0.42	%	2.74	%
S&P 500 Index		2.96	%	9.41	%
Lipper Large-Cap Core Funds Category Average		1.21	%	5.97	%

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.smithbarneymutualfunds.com.

Performance figures may reflect reimbursements 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 1 shares returned -0.06%, Class B shares returned -0.83% and Class C shares returned -0.49% over the six months ended October 31, 2004. Excluding sales charges, Class 1 shares returned 3.41%, Class B shares returned 1.90% and Class C shares returned 2.57% over the twelve months ended October 31, 2004.

Lipper, Inc. is a major independent mutual-fund tracking organization. Returns are based on the period ended October 31, 2004, calculated among the 956 funds for the six-month period and among the 933 funds for the 12-month period in the fund’s Lipper category including the reinvestment of dividends and capital gains, if any, and excluding sales charges.

uncertainty over the geopolitical situation, concerns about rising interest rates and questions about the U.S. presidential race kept both businesses and many investors uncertain about the overall equity marketplace. In addition, high oil prices were a negative for the consumer.

Performance Review

For the 12-months ended October 31, 2004, Class A shares of the Smith Barney Dividend Strategy Fund, excluding sales charges, returned 2.74%. These shares underperformed the fund’s unmanaged benchmark, the S&P 500 Index^viii, which returned 9.41% for the same period. They also underperformed the Lipper large-cap core funds category average¹, which was 5.97%.

Fund Overview

Both stock selection and sector allocation had a negative effect on fund performance in comparison to the benchmark, with the majority of underperformance due to stock selection, especially in the consumer discretionary and information technology sectors. Contributors to performance came largely from the industrials and consumer staples sectors.

Contributors to Performance

On a sector basis, the greatest returns during the one-year period were experienced by the energy, utilities and industrials sectors. The sectors that performed least well for the year were technology, healthcare and consumer staples.

Relative to the fund’s benchmark, the S&P 500 Index,^viii our best performing equity during this period was Biogen Idec Inc., a biotechnology company involved in research and development, manufacturing and commercialization of targeted therapies for the treatment of cancer and autoimmune and inflammatory diseases. Canadian National RailwayCo., Tyco International, Ltd., Exxon Mobil Corp. and St. Jude Medical Inc. were among the other top relative performers. The fund maintained its positions in all five stocks at the close of the period.

Detractors from Performance

The information technology and consumer discretionary sectors detracted most from the fund’s performance for the one-year period, specifically, e-commerce company InterActiveCorp in the consumer discretionary area. In the information technology sector, holdings that weakened our overall performance included Veritas Software Corp., an application server software developer, BEA Systems Inc., an application infrastructure software company, Intel Corp., which manufactures semiconductor chips and supplies advanced technology solutions for the computing and communications industries, and lastly, Siebel Systems Inc., which provides business applications software. The fund had closed its positions in Veritas Software, BEA Systems and Siebel Systems by the close of the period but continued to hold shares of InterActive and Intel.

Thank you for your investment in the Smith Barney Dividend Strategy Fund. As ever, we appreciate that you have chosen us to manage your assets and we remain focused on seeking to achieve the fund’s investment goals.

Sincerely,

Lawrence B. Weissman, CFA

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 May 1, 2004 and held for the six months ended October 31, 2004.

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 Ratios		Expenses Paid During the Period(3)
Class 1	(0.06	)%	$	1,000.00	$	999.40	0.91	%	$	4.57
Class A	(0.42	)		1,000.00		995.80	1.59			7.98
Class B	(0.83	)		1,000.00		991.70	2.40			12.02
Class C(4)	(0.49	)		1,000.00		995.10	1.80			9.03

(1) For the six months ended October 31, 2004.

(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 charges with respect to Class 1 and 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 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 have been lower.

(3) Expenses (net of voluntary waiver) are equal to each class’ 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 366.

(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)

Notes to Financial Statements

1. Organization and Significant Accounting Policies

The Smith Barney Dividend Strategy Fund (formerly known as Smith Barney Large Cap Core Fund) (“Fund”), a separate investment fund of the Smith Barney Investment Series (“Trust”), a Massachusetts business trust, is registered under the Investment Company Act of 1940, as amended (“1940 Act”) as a diversified, 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 are 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 traded on national securities markets are valued at the closing prices on such markets. Securities primarily traded on foreign exchanges are generally valued at the preceding closing values of such securities on their respective exchanges. Over-the-counter securities are valued on the basis of the bid price at the close of business on each day. U.S. government and agency obligations are valued at the average between bid and ask prices in the over-the counter market. Securities listed on the NASDAQ National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price on that day, at the last sale price. When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund may value these investments at fair value as determined in accordance with the procedures approved by the Fund’s Board of Trustees. Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant ADRs and futures contracts. Short-term obligations maturing within 60 days are valued at amortized cost, which approximates value.

(b) Repurchase Agreements. When entering into repurchase agreements, it is the Fund’s policy that a custodian takes possession of the underlying collateral securities, the value of which at least equals the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market to ensure the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited.

(c) 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 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. Risks of entering into futures contracts for hedging purposes include the possibility that a change in the value of the contract may not correlate with the changes in the value of the investments hedged. In addition, the purchase of a futures contract involves the risk that the Fund could lose more than the original margin deposit and subsequent payments required for a futures transaction.

(d) Forward Foreign Currency Contracts. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price on a future date. The contract is marked-to-market daily and the change in value is recorded by the Fund as an unrealized gain or loss. When a forward foreign currency contract is extinguished, through

22        Smith Barney Dividend Strategy Fund      |      2004 Annual Report

Notes to Financial Statements (continued)

either delivery or offset by entering into another forward foreign currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was extinguished or offset. The Fund bears the market risk that arises from changes in foreign currency exchange rates and the credit risk should a counterparty fail to meet the terms of such contracts.

(e) Investment Transactions and Investment Income. Security transactions are accounted for on trade date. Dividend income is recorded on the ex-dividend date and foreign dividend income is recorded on the ex-dividend date or as soon as practical after the Fund determine the existence of a dividend declaration after exercising reasonable due diligence. Gains or losses on the sale of securities are calculated by using the specific identification method.

(f) Foreign Currency Translation. The books and records of the Fund are maintained in U.S. dollars. Transactions denominated in foreign currencies are recorded at the current prevailing exchange rates. All assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts at the current exchange rate at the end of the period. Translation gains or losses resulting from changes in the exchange rate during the reporting period and realized gains and losses on the settlement of foreign currency transactions are reported in the statement of operations for the current period. The Fund does not isolate that portion of realized gains and losses on investments in securities, which are due to changes in the foreign exchange rate from that which is due to changes in market prices of equity securities.

(g) Dividends and Distributions to Shareholders. Dividends and distributions to shareholders are recorded by the Fund on the ex-dividend date. The Fund distributes dividends and capital gains, if any, at least annually. The character of income and gains to be distributed is determined in accordance with income tax regulations which may differ from GAAP.

(h) Class Accounting. Class specific expenses are charged to each class; management fees, general fund expenses, income and gains and/or losses are allocated on the basis of relative net assets of each class or on another reasonable basis;

(i) Federal Income 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 income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

(j) Reclassifications. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $2,122 has been reclassified between accumulated net realized loss from investment transactions and futures contracts and undistributed net investment income as a result of permanent differences attributable to foreign currency transactions. This reclassification has no effect on net assets or net asset values per share.

2. Management Agreement and Other Transactions

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

Average Daily Net Assets	Annual Rate
First $1 billion	0.65	%
Next $1 billion	0.60
Next $1 billion	0.55
Next $1 billion	0.50
Over $4 billion	0.45

23        Smith Barney Dividend Strategy Fund      |      2004 Annual Report

Notes to Financial Statements (continued)

During the year ended October 31, 2004, SBFM voluntarily waived a portion of the Fund’s management fee in the amount of $24,868.

Effective November 1, 2004, SBFM imposed a voluntary expense limitation of 1.25% and 2.00% for Class A and Class B, respectively.

Citicorp Trust Bank, fsb. (“CTB”), another subsidiary of Citigroup, acts as the Fund’s transfer agent. PFPC Inc. (“PFPC”) and Primerica Shareholder Services (“PSS”), another subsidiary of Citigroup, act as the Fund’s sub-transfer agents. CTB receives account fees and asset-based fees that vary according to the size and type of account. PFPC and PSS are responsible for shareholder recordkeeping and financial processing for all shareholder accounts and are paid by CTB. For the year ended October 31, 2004, the Fund paid transfer agent fees of $8,489,868 to CTB.

Citigroup Global Markets Inc. (“CGM”) and PFS Distributors, Inc., both of which are subsidiaries of Citigroup, act as the Fund’s distributors.

On April 29, 2004, the Fund’s Class L shares were renamed as Class C shares. On February 2, 2004, sales charges on these shares were eliminated.

There are maximum sales charges of 8.50% and 5.00% for Class 1 and A shares, respectively. There is a contingent deferred sales charge (“CDSC”) of 5.00% on Class B shares, which applies if redemption occurs within one year from purchase payment. This CDSC declines 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 $1,000,000 in the aggregate. These purchases do not incur an initial sales charge.

For the year ended October 31, 2004, CGM and its affiliates received sales charges of approximately $24,000 and $3,000 on sales of the Fund’s Class A and C shares, respectively. In addition, CDSCs paid to CGM and its affiliates for the year ended October 31, 2004 were approximately $32,000 for Class B shares.

For the year ended October 31, 2004, CGM and its affiliates received brokerage commission of $62,480.

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

The Trustees of the Funds have adopted a Retirement Plan (“Plan”) for all Trustees who are not “interested persons” of the Fund, within the meaning of the 1940 Act. Under the Plan, all Trustees are required to retire from the Board as of the last day of the calendar year in which the applicable Trustee attains age 75 (certain Trustees who had already attained age 75 when the Plan was adopted were required to retire effective December 31, 2003). Trustees may retire under the Plan before attaining the mandatory retirement age. Trustees who have served as Trustee of the Trust or any of the investment companies associated with Citigroup for at least ten years when they retire are eligible to receive the maximum retirement benefit under the Plan. The maximum retirement benefit is an amount equal to five times the amount of retainer and regular meeting fees payable to a Trustee during the calendar year ending on or immediately prior to the applicable Trustee’s retirement. Amounts under the Plan may be paid in installments or in a lump sum (discounted to present value). Benefits under the Plan are unfunded. Two former Trustees are currently receiving payments under the Plan. In addition, two other Trustees elected to receive a lump sum payment from this Plan during this period.

24        Smith Barney Dividend Strategy Fund      |      2004 Annual Report

Notes to Financial Statements (continued)

Certain of the Trustees are covered by a prior retirement plan. Under the prior plan, retirement benefits are payable for a ten-year period following retirement, with the annual payment to be based upon the Trustee’s compensation from the Trust during calendar year 2000. Trustees with more than five but less than ten years of service at retirement will receive a prorated benefit. In order to receive benefits under the current Plan, a Trustee must waive all rights under the prior plan prior to receiving payment under either plan. At October 31, 2004, $421,102 is accrued in connection with these plans.

8. Additional Information

In connection with an investigation previously disclosed by Citigroup, the Staff of the Securities and Exchange Commission (“SEC”) has notified Citigroup Asset Management (“CAM”), the Citigroup business unit that includes the funds’ investment manager and other investment advisory companies; Citigroup Trust Bank (“CTB”), an affiliate of CAM; Thomas W. Jones, the former CEO of CAM; and three other individuals, one of whom is an employee and the other two of whom are former employees of CAM, that the SEC Staff is considering recommending a civil injunctive action and/or an administrative proceeding against each of them relating to the creation and operation of an internal transfer agent unit to serve various CAM-managed funds.

In 1999, CTB entered the transfer agent business. CTB hired an unaffiliated subcontractor to perform some of the transfer agent services. The subcontractor, in exchange, had signed a separate agreement with CAM in 1998 that guaranteed investment management revenue to CAM and investment banking revenue to a CAM affiliate. The subcontractor’s business was later taken over by PFPC Inc., and at that time the revenue guarantee was eliminated and a one-time payment was made by the subcontractor to a CAM affiliate.

CAM did not disclose the revenue guarantee when the boards of various CAM-managed funds hired CTB as transfer agent. Nor did CAM disclose to the boards of the various CAM-managed funds the one-time payment received by the CAM affiliate when it was made.

In addition, the SEC Staff has indicated that it is considering recommending action based on the adequacy of the disclosures made to the fund boards that approved the transfer agency arrangement, CAM’s initiation and operation of, and compensation for, the transfer agent business and CAM’s retention of, and agreements with, the subcontractor.

Citigroup is cooperating fully in the investigation and will seek to resolve the matter in discussions with the SEC Staff. Although there can be no assurance, Citigroup does not believe that this matter will have a material adverse effect on the Fund. As previously disclosed, CAM has already agreed to pay the applicable funds, primarily through fee waivers, a total of approximately $17 million (plus interest) that is the amount of the revenue received by Citigroup relating to the revenue guarantee.

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.

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 October 31, 2004 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 the Fund as of October 31, 2004, 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 financial highlights for each of the years in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

(c) Tax Fees for Smith Barney Investment Series of $17,500 and $16,900 for the years ended 10/31/04 and 10/31/03.

(d) All Other Fees for Smith Barney Investment Series of $0 and $0 for the years ended 10/31/04 and 10/31/03.

(e) (1) Audit Committee’s pre–approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by Smith Barney Fund Management LLC or Salomon Brothers Asset Management Inc. or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to the Adviser and any Covered Service Providers if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. 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.

(2) For the Smith Barney Investment Series, the percentage of fees that were approved by the audit committee, with respect to: Audit-Related Fees were 100% and 100% for the years ended 10/31/04 and 10/31/03; Tax Fees were 100% and 100% for the years ended 10/31/04 and 10/31/03; and

(h) Yes. The Smith Barney Investment Series’s 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 Investment Series or to Service Affiliates which were required to be pre-approved were pre-approved as required.

EX 99.CODE ETH

SARBANES-OXLEY ACT CODE OF ETHICS

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.
