Jay Gerken R. JAY GERKEN, CFA Chairman, President and Chief Executive Officer Dear Shareholder, We are pleased to present the annual report for the Smith Barney Large Cap Core Fund. After a torturous three-year bear market, the U.S. stock market has rallied strongly so far in 2003 as geopolitical uncertainties eased and investors began to look forward to better economic times. The recent performance of the U.S. economy has supported an improvement in investor sentiment and corporate earnings. If you have any questions about recent economic events or investing in a recovering economy, we urge you to talk with your financial adviser. As always, we thank you for entrusting your assets to us, and we look forward to helping you continue to meet your financial goals. Please read on to learn more about your fund's performance and the Manager's strategy. Sincerely, /s/ R. Jay Gerken R. Jay Gerken, CFA Chairman, President and Chief Executive Officer November 12, 2003 1 Smith Barney Large Cap Core Fund | 2003 Annual Report MANAGER OVERVIEW Performance Review For the 12 months ended October 31, 2003, Class 1 shares of the Smith Barney Large Cap Core Fund, excluding sales charges, returned 16.03%. These shares underperformed the fund's unmanaged benchmark, the S&P 500 Index,/i/ which returned 20.79% for the same period. They also underperformed the average of the fund's Lipper peer group of large-cap core funds, which returned 17.75% for the same period./1/ The fund's underperformance is due primarily to the marked differences in the performance of small- and large- cap stocks in the past year's stock market rally. This past year has been an unusual one in that low-priced, high volatility stocks of smaller, lesser-known companies significantly outperformed stocks of many larger, well-known companies with good balance sheets, sound business plans, and favorable long term outlooks. Because the fund does not invest in small- or micro-cap companies, which benefited the most in the market rally, its performance could not match that of funds that invest in the broad market, or those funds that do invest in stocks of smaller companies. Overview Early in the fund's fiscal year, the economy was not showing any clear signs of improvement and the stock market was testing multiyear lows. The Federal government's aggressive monetary and fiscal policies finally manifested themselves in the third calendar quarter of 2003, with the highest rate of gross domestic product (GDP)/ii/ growth in a single quarter that the U.S. had seen in almost two decades. Corporate expenses were cautiously controlled during the economic downturn in place at the start of the period, which allowed for dramatic operating leverage as modest revenue increases started to translate into positive earnings surprises in the second and third calendar quarters. This was the backdrop for the dramatic rebound in the equity markets that began after the end of the first calendar quarter. Many of the biggest gainers in the ensuing market rally were low-priced, single-digit stocks that had been oversold and were among the worst performers over the previous three years. What Affected Performance As of the end of the period, the fund's largest sector concentrations were in Financials, Information Technology and Healthcare. While we continued to emphasize these sectors, during the period we reduced the fund's weightings in the Financials and Healthcare sectors and increased exposure to the Information Technology sector. Not surprisingly, the largest contributors to the fund's performance during the period came from the Information Technology sector, which outperformed all other sectors handily. The biggest single contributor to the fund's performance for the period was its position in PERFORMANCE SNAPSHOT AS OF OCTOBER 31, 2003 (excluding sales charges) 6 Months 12 Months Class 1 Shares 12.36% 16.03% S&P 500 Index 15.62% 20.79% Average of Lipper large-cap core funds 14.42% 17.75% Class 1 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. Only eligible Class 1 shareholders may purchase additional Class 1 shares. Results for other share classes may vary. The S&P 500 Index is a market capitalization-weighted index of 500 widely held common stocks. Please note that an investor cannot invest directly in an index. Lipper Inc. is a major independent mutual-fund tracking organization. Returns are based on the 12 month period ended October 31, 2003, calculated among 1,098 funds for the six-month period and among 1,064 funds for the 12-month period, in the fund's Lipper peer group including the reinvestment of dividends and capital gains and excluding sales charges. All figures represent past performance and are not a guarantee of future results. Principal value and investment returns will fluctuate and investors' shares, when redeemed may be worth more or less than their original cost. /1/Lipper Inc. is a major independent mutual-fund tracking organization.

Intel is one of the largest semiconductor manufacturers in the world and was a big beneficiary in the recovery in demand for semiconductors used in PCs, laptops and corporate network servers. Intel has been reaping the benefits of significant investments it made in research and development and in manufacturing over the last several years. The other two top contributors were also fund holdings in the Information Technology sector, Cisco Systems Inc. and VERITAS Software Corp. Cisco manufactures and sells computer networking and communications products worldwide. Cisco benefited from market share gains in the network router and switch segments, growth of emerging technologies such as Voice Over Internet Protocol ("VOIP") telephony and a general improvement in the business environment. VERITAS Software provides data availability software that enables customers to protect, manage, and access their critical information and data. During the last twelve months, VERITAS has benefited from market share gains in the data back-up and recovery segments, new foundation products designed for the IBM/AIX platform and a general pickup in business spending as well. While the fund's overall performance was positive, some stocks in the portfolio lost value during the period, detracting from performance. The largest single detractor from fund performance during the period was hospital operator HCA, Inc. in the Healthcare sector. HCA suffered a considerable drop in share price during the period, falling from a 5-year high of $52.05 per share in June of 2002 (before the start of the period) to a low of $27.30 per share on April 16, 2003. The company has been the focus of a number of government investigations, as well as civil and criminal suits brought against it, alleging fraud and accounting irregularities, and was no longer held by the fund as of the end of October. American International Group Inc. ("AIG") in the Financials sector was the second largest detractor from fund performance during the period. AIG is one of the world's largest insurance firms, an industry that was hit hard by losses related to terrorism in 2001 and by the stock market's difficulties in much of 2002. The third biggest detractor from fund performance for the period was Kraft Foods Inc. in the Consumer Staples sector. The company's stock suffered during the period in part because of investor concerns over ties to its parent company, Altria Group (formerly Phillip Morris), and its exposure to ongoing tobacco litigation issues and a decline in the long-term growth expectations for the company. Kraft was no longer held by the fund as of the end of October.

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.

Significant Accounting Policies The 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. This Trust consists of this Fund and six other separate investment funds: Smith Barney International Fund (formerly known as Smith Barney International Aggressive Growth Fund), SB Growth and Income Fund (formerly known as Smith Barney Growth and Income Fund), Smith Barney Large Cap Core Portfolio, Smith Barney Premier Selections All Cap Growth Portfolio, Smith Barney Growth and Income Portfolio and SB Government Portfolio (formerly known as Smith Barney Government Portfolio). The financial statements and financial highlights for the other portfolios are presented in separate shareholder reports. The significant accounting policies consistently followed by the Fund are: (a) security transactions are accounted for on trade date; (b) securities traded on national securities markets are valued at the closing prices on such markets or, if there were no sales during the day, at fair value determined by or under the direction of the Board of Trustees; securities primarily traded on foreign exchanges are generally valued at the preceding closing values of such securities on their respective exchanges, except that when a significant event, subsequent to the time a value was so established, is likely to have significantly changed the value, then the fair value of those securities will be determined by consideration of other factors by or under the direction of the Board of Trustees or its delegates; 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; (c) securities maturing within 60 days are valued at cost plus accreted discount or minus amortized premium, which approximates value; (d) securities for which market quotations are not available will be valued in good faith at fair value by or under the direction of the Board of Trustees; (e) interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis; ( f ) dividend income is recorded on the ex-dividend date; 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; (g) gains or losses on the sale of securities are calculated by using the specific identification method; (h) 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; (i) the accounting records of the Fund are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies against U.S. dollars on the date of valuation. Purchases and sales of securities, and income and expenses are translated at the rate of exchange quoted on the respective date that such transactions are recorded. Differences between income and expense amounts recorded and collected or paid are adjusted when reported by the custodian bank; ( j) realized gain and loss on foreign currency includes the net realized amount from the sale of currency and the amount realized between trade date and settlement date on security transactions; (k) the character of income and gains to be distributed is determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America. At October 31, 2003, reclassifications were made to the Fund's capital accounts to reflect permanent book/tax differences and income and gains available for distributions under income tax regulations. Net investment income, net realized gains and net assets were not affected by this adjustment; (l) the Fund intends to comply with the requirements of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes; and (m) 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. 13 Smith Barney Large Cap Core Fund | 2003 Annual Report NOTES TO FINANCIAL STATEMENTS (CONTINUED) Also, the Fund may enter into forward foreign exchange contracts in order to hedge against foreign currency risk. These contracts are marked-to-market daily, by recognizing the difference between the contract exchange rate and the current market rate as an unrealized gain or loss. Realized gains or losses are recognized when contracts are settled or offset by entering into another forward exchange contract. The Fund from time to time may also enter into options and/or futures contracts typically to hedge market or currency risk. 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 - ---------------------------------------------------------------------------- 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, 2003, the Fund paid transfer agent fees of $10,945,285 to CTB. Citigroup Global Markets Inc. ("CGM") (formerly known as Salomon Smith Barney Inc.) and PFS Distributors, Inc., both of which are subsidiaries of Citigroup, act as the Fund's distributors. For the year ended October 31, 2003, CGM and its affiliates received brokerage commissions of $156,111. There are maximum initial sales charges of 8.50%, 5.00% and 1.00% for Class 1, A and L 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 L shares also 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, 2003, CGM and its affiliates received sales charges of approximately $5,150,000, $2,102,000 and $11,000 on sales of the Fund's Class 1, A and L shares, respectively. In addition, CDSCs paid to CGM and its affiliates for the year ended October 31, 2003 were approximately $813,000 for Class B shares. All officers and one Trustee of the Trust are employees of Citigroup or its affiliates. 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 are required to retire effective December 31, 2003). Trustees may retire under the Plan before 14 Smith Barney Large Cap Core Fund | 2003 Annual Report NOTES TO FINANCIAL STATEMENTS (CONTINUED) 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. Two additional Trustees have announced their intention to retire, effective December 31, 2003. The amount of benefits to be paid under the Plan cannot currently be determined for current Trustees. Messrs. Carlton, Cocanougher, Gross, Merten and Pettit also 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. Total aggregate retirement benefits accrued under the prior plan for the year ended October 31, 2003 were $85,271. The amount of benefits to be paid under the prior plan cannot currently be determined for these Trustees. 3. Investments During the year ended October 31, 2003, the aggregate cost of purchases and proceeds from sales of investments (including maturities of long-term investments, but excluding short-term investments) were as follows: - -------------------------------------------------------------------------------- Purchases $1,996,562,567 - -------------------------------------------------------------------------------- Sales 2,231,203,015 - -------------------------------------------------------------------------------- At October 31, 2003, the aggregate gross unrealized appreciation and depreciation of investments for Federal income tax purposes were as follows: - ------------------------------------------------------------------------------ Gross unrealized appreciation $644,189,458 Gross unrealized depreciation (45,749,911) - ------------------------------------------------------------------------------ Net unrealized appreciation $598,439,547 - ------------------------------------------------------------------------------ 4. Repurchase Agreements The Fund purchases (and the custodian takes possession of ) U.S. government securities from securities dealers subject to agreements to resell the securities to the sellers at a future date (generally, the next business day), at an agreed-upon higher repurchase price. The Fund requires continual maintenance of the market value (plus accrued interest) of the collateral in amounts at least equal to the repurchase price. 5. Futures Contracts Securities or cash equal to the initial margin amount are either deposited with the broker or segregated by the custodian upon entering into the futures contract. Additional securities are also segregated up to the current market value of the futures contracts. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking-to-market" on a daily basis to reflect the market value of the contract at the end of each day's trading. Variation margin payments are made or received and recognized as assets due from or liabilities due to broker, depending upon whether unrealized gains or losses are incurred. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (and cost of ) the closing transaction and the Fund's 15 Smith Barney Large Cap Core Fund | 2003 Annual Report NOTES TO FINANCIAL STATEMENTS (CONTINUED) basis in the contract. The Fund enters into such contracts typically to hedge a portion of its portfolio. The Fund bears the market risk that arises from changes in the value of the financial instruments and securities indices. At October 31, 2003, the Fund did not hold any futures contracts. 6. Class Specific Expenses Pursuant to a Service Plan, the Fund pays a service fee with respect to its Class A, B and L shares calculated at the annual rate of 0.25% of the average daily net assets with respect to Class A shares and calculated at the annual rate of 1.00% of the average daily net assets of Class B and L shares. For the year ended October 31, 2003, total Service Plan fees, which are accrued daily and paid monthly, were as follows: Class A Class B Class L - ---------------------------------------------------------------------------- Service Plan Fees $920,241 $2,874,541 $53,117 - ---------------------------------------------------------------------------- For the year ended October 31, 2003, total Shareholder Servicing fees were as follows: Class 1 Class A Class B Class L - ---------------------------------------------------------------------------- Shareholder Servicing Fees $8,647,745 $3,375,675 $2,942,250 $2,230 - ---------------------------------------------------------------------------- For the year ended October 31, 2003, total Shareholder Communication expenses were as follows: Class 1 Class A Class B Class L - ---------------------------------------------------------------------------- Shareholder Communication Expenses $182,756 $79,656 $64,619 $662 - ---------------------------------------------------------------------------- 7. Distributions Paid to Shareholders by Class Year Ended Year Ended October 31, 2003 October 31, 2002 - ------------------------------------------------------------------------------ Class 1 Net investment income -- $15,313,890 Net realized gains -- 1,482,275 Capital -- 1,694,562 - ----------------------------------------------------------------------------- Total -- $18,490,727 - ----------------------------------------------------------------------------- Class A Net realized gains -- $ 226,265 - ----------------------------------------------------------------------------- Total -- $ 226,265 - ----------------------------------------------------------------------------- Class B Net realized gains -- $ 195,425 - ----------------------------------------------------------------------------- Total -- $ 195,425 - ----------------------------------------------------------------------------- Class L Net realized gains -- $ 3,012 - ----------------------------------------------------------------------------- Total -- $ 3,012 - ----------------------------------------------------------------------------- 16 Smith Barney Large Cap Core Fund | 2003 Annual Report NOTES TO FINANCIAL STATEMENTS (CONTINUED) 8. Capital Loss Carryforward At October 31, 2003, the Fund had, for Federal income tax purposes, approximately $300,819,000 of unused capital loss carryforwards available to offset future capital gains. To the extent that these capital carryforward losses are used to offset capital gains, it is probable that the gains so offset will not be distributed. The amount and year of expiration for each carryforward loss is indicated below. Expiration occurs on October 31 of the year indicated: 2010 2011 - --------------------------------------------------------------------------- Carryforward Amounts $244,521,000 $56,298,000 - --------------------------------------------------------------------------- 9. Income Tax Information and Distributions to Shareholders At October 31, 2003, the tax basis components of distributable earnings were: - ---------------------------------------------------------------- Undistributed ordinary income $ 3,458,927 - ---------------------------------------------------------------- Accumulated capital losses (300,818,633) - ---------------------------------------------------------------- Unrealized appreciation 598,439,547 - ---------------------------------------------------------------- The difference between book basis and tax basis unrealized appreciation is attributable primarily to wash sale loss deferrals. For the year ended October 31, 2003, the Fund did not make any distributions. 10. Shares of Beneficial Interest At October 31, 2003, the Fund had five classes of beneficial interest, 1, A, B, L and Y, of which four classes are outstanding, each with a par value of $0.00001 per share. There are an unlimited number of shares authorized. Transactions in shares of each class were as follows: Year Ended Year Ended October 31, 2003 October 31, 2002 -------------------------- -------------------------- Shares Amount Shares Amount - -------------------------------------------------------------------------------------- Class 1 Shares sold 5,191,779 $ 75,863,431 5,514,504 $ 90,519,719 Shares issued on reinvestment -- -- 1,001,831 18,490,718 Shares reacquired (19,635,110) (283,537,780) (24,219,440) (389,744,381) - ------------------------------------------------------------------------------------- Net Decrease (14,443,331) $(207,674,349) (17,703,105) $(280,733,944) - ------------------------------------------------------------------------------------- Class A Shares sold 4,762,832 $ 68,607,615 5,825,048 $ 96,435,608 Shares issued on reinvestment -- -- 15,797 225,263 Shares reacquired (4,237,240) (60,363,852) (4,989,579) (79,284,641) - ------------------------------------------------------------------------------------- Net Increase 525,592 $ 8,243,763 851,266 $ 17,376,230 - ------------------------------------------------------------------------------------- Class B Shares sold 2,968,621 $ 40,777,367 4,315,346 $ 68,774,689 Shares issued on reinvestment -- -- 14,163 194,179 Shares reacquired (4,689,891) (64,100,603) (5,960,574) (93,075,362) - ------------------------------------------------------------------------------------- Net Decrease (1,721,270) $ (23,323,236) (1,631,065) $ (24,106,494) - ------------------------------------------------------------------------------------- Class L Shares sold 151,984 $ 2,149,504 144,571 $ 2,452,731 Shares issued on reinvestment -- -- 192 2,731 Shares reacquired (93,791) (1,289,918) (115,607) (1,841,389) - ------------------------------------------------------------------------------------- Net Increase 58,193 $ 859,586 29,156 $ 614,073 - ------------------------------------------------------------------------------------- 17 Smith Barney Large Cap Core Fund | 2003 Annual Report NOTES TO FINANCIAL STATEMENTS (CONTINUED) 11. Subsequent Event The Fund has received the following information from Citigroup Asset Management ("CAM"), the Citigroup business unit which includes the Fund's Investment Manager and other investment advisory companies, all of which are indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an affiliate, into the transfer agent business in the period 1997-1999. As CAM currently understands the facts, at the time CAM decided to enter the transfer agent business, CAM sub-contracted for a period of five years certain of the transfer agency services to a third party and also concluded a revenue guarantee agreement with this sub-contractor providing that the sub-contractor would guarantee certain benefits to CAM or its affiliates (the "Revenue Guarantee Agreement"). In connection with the subsequent purchase of the sub-contractor's business by an affiliate of the current sub-transfer agent (PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee Agreement was amended eliminating those benefits in exchange for arrangements that included a one-time payment from the sub-contractor. The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue Guarantee Agreement with the sub-contractor at the time the Boards considered and approved the transfer agent arrangements. Nor were the Boards informed of the subsequent amendment to the Revenue Guarantee Agreement when that occurred. CAM has begun to take corrective actions. CAM will pay to the applicable funds $16 million (plus interest) that CAM and its affiliates received from the Revenue Guarantee Agreement and its amendment. CAM also plans an independent review to verify that the transfer agency fees charged by CAM were fairly priced as compared to competitive alternatives. CAM is instituting new procedures and making changes designed to ensure no similar arrangements are entered into in the future. CAM has briefed the SEC, the New York State Attorney General and other regulators with respect to this matter, as well as the U.S. Attorney who is investigating the matter. CAM is cooperating with governmental authorities on this matter, the ultimate outcome of which is not yet determinable. 18 Smith Barney Large Cap Core Fund | 2003 Annual Report FINANCIAL HIGHLIGHTS For a share of each class of beneficial interest outstanding throughout each year ended October 31, unless otherwise noted: Class 1 Shares 2003/(1)/ 2002/(1)/ 2001/(1)/ 2000/(1)/ 1999/(1)/ -

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. The financial highlights for each year ended October 31, 1999 were audited by other auditors whose report thereon, dated December 15, 1999, expressed an unqualified opinion on those financial highlights. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2003 by correspondence with the custodian and broker. As to securities purchased or sold but not received or delivered, we performed other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Fund as of October 31, 2003, 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 four-year period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ KPMG LLP New York, New York December 10, 2003 23 Smith Barney Large Cap Core Fund | 2003 Annual Report ADDITIONAL INFORMATION (UNAUDITED) Information about Trustees and Officers The business and affairs of the Smith Barney Large Cap Core Fund ("Fund") are managed under the direction of the Fund's Board of Trustees.
