You will notice in the following pages that we have begun to implement some changes to your shareholder report and we will be reflecting other changes in future reports. Our aim is to make meaningful improvements in reporting on the management of your Fund and its performance, not just to enact change for change's sake. Please bear with us during this transition period. We know that you have questions about fund managers' decisions and plans, and we want to be sure that you have easy access to the information you need. Keeping investors informed is, and always will be, one of my top priorities as Chairman of your Fund. To that end, we encourage you to go to our website: www.smithbarneymutualfunds.com/1/ where you can find additional insight on your Fund. I invite you to read this report in full. Please take the opportunity to talk to your financial adviser about this report or any other questions or concerns you have about your Fund and your financial future. As always, thank you for entrusting your assets to us. We look forward to helping you continue to meet your financial goals. Sincerely, /s/ R Jay Gerken R.

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 ("1940 Act"), as amended, 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, 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 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 the current quoted bid price; 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 occurrence, 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, 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 are determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America; (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 tax; 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. 8 Smith Barney Large Cap Core Fund | 2003 Semi-Annual Report to Shareholders NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (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. 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 Global Fund Services ("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 six months ended April 30, 2003, the Fund paid transfer agent fees of $6,068,172 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. In addition, CGM and certain other broker-dealers continue to sell Fund shares to the public as members of the selling group. For the six months ended April 30, 2003, CGM and its affiliates received brokerage commissions of $47,731. 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. 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 the first year of purchase. In certain cases, Class A shares have a 1.00% CDSC, which applies if redemption occurs within the first year of purchase. This CDSC only applies to those purchases of Class A shares, which, when combined with current holdings of Class A shares, equal or exceed $1,000,000 in the aggregate. These purchases do not incur an initial sales charge. For the six months ended April 30, 2003, CGM and its affiliates received sales charges of approximately $2,810,000, $1,125,000 and $5,000 on sales of the Fund's Class 1, A and L shares, respectively. In addition, CDSCs paid to CGM and its affiliates for the six months ended April 30, 2003 were approximately $457,000 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 attaining the mandatory retirement age. Trustees who have served as Trustee of the Trust or any of the investment compa- 9 Smith Barney Large Cap Core Fund | 2003 Semi-Annual Report to Shareholders NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) nies 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. 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 six months ended April 30, 2003 were $42,285. The amount of benefits to be paid under the prior plan cannot currently be determined for these Trustees. 3. Investments During the six months ended April 30, 2003, the aggregate cost of purchases and proceeds from sales of investments (including maturities of long-term securities, but excluding short-term securities) were as follows: - ------------------------------------------------ Purchases $606,622,275 - ------------------------------------------------ Sales 703,337,291 - ------------------------------------------------ At April 30, 2003, the aggregate gross unrealized appreciation and depreciation of investments for Federal income tax purposes were substantially as follows: - ------------------------------------------------- Gross unrealized appreciation $ 457,728,416 Gross unrealized depreciation (154,661,773) - ------------------------------------------------- Net unrealized appreciation $ 303,066,643 - ------------------------------------------------- 4. Repurchase Agreements The Fund purchases (and its 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 Initial margin deposits made upon entering into futures contracts are recognized as assets. The initial margin is segregated by the custodian. 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 basis in the contract. The Fund enters into such contracts 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 (futures contracts) and the credit risk should a counterparty fail to perform under such contracts. At April 30, 2003, the Fund did not hold any futures contracts. 10 Smith Barney Large Cap Core Fund | 2003 Semi-Annual Report to Shareholders NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) 6.
