 LETTER FROM THE CHAIRMAN

Dear Shareholder,

The U.S. economy overcame a number of obstacles and continued to expand during the six-month reporting period. Rising interest rates, record high oil prices, and geopolitical issues threatened to send the economy into a “soft patch.” However, when all was said and done, first quarter 2005 gross domestic product (“GDP”)ⁱ growth was 3.8%, mirroring the solid gain that occurred during the fourth quarter of 2004.

Given the overall strength of the economy, the Federal Reserve Board (“Fed”)ⁱⁱ continued to raise interest rates over the period in an attempt to ward off inflation. Following five rate hikes from June 2004 through December 2004, the Fed again increased its target for the federal funds rateⁱⁱⁱ in 0.25% increments four additional times during the reporting period. All told, the Fed’s nine rate hikes brought the target for the federal funds rate from 1.00% to 3.25%.

During the six months covered by this report, the U.S. stock market was relatively flat, with the S&P 500 Index^iv returning -0.81%. Stocks were weak early in the reporting period, as the issues discussed above caused investors to remain on the sidelines. Equities then rallied in the second quarter of 2005, as the economy appeared to be on solid footing and inflation was largely under control. Looking at the reporting period as a whole, mid-cap stocks generated superior returns, with the Russell Midcap^v, Russell 1000^vi, and Russell 2000^vii Indexes returning 3.92%, 0.11%, and -1.25%, respectively. From a market style perspective, value-oriented stocks outperformed their growth counterparts.

Within this environment, the Fund performed as follows:¹

PERFORMANCE OF THE FUND

AS OF JUNE 30, 2005

(unaudited)

	6 Months
Social Awareness Stock Portfolio		-1.48%
S&P 500 Index		-0.81%
Lipper Variable Specialty/ Miscellaneous Funds Category Average		-2.94%

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.

Fund returns assume the reinvestment of all distributions at net asset value and the deduction of all Fund expenses.

For the six months ended June 30, 2005, the Social Awareness Stock Portfolio returned -1.48%. The Lipper Variable Specialty/ Miscellaneous Funds Category Average² decreased 2.94% and the Fund’s unmanaged benchmark, the S&P 500 Index returned -0.81% for the same period.

1

The Fund is an underlying investment option of various variable annuity and variable life insurance products. The Fund’s performance returns do not reflect the deduction of expenses imposed in connection with investing in variable annuity or variable life insurance contracts, such as administrative fees, account charges and surrender charges, which, if reflected, would reduce the performance of the Fund. Past performance is no guarantee of future results.

2

Lipper, Inc. is a major independent mutual-fund tracking organization. Returns are based on the six-month period ended June 30, 2005, including the reinvestment of dividends and capital gains distributions, if any, calculated among the 133 funds in the Fund’s Lipper category.

Special Shareholder Notice

On June 24, 2005, Citigroup Inc. (“Citigroup”) announced that it has signed a definitive agreement under which Citigroup will sell substantially all of its worldwide asset management business to Legg Mason, Inc. (“Legg Mason”).

As part of this transaction, Smith Barney Fund Management LLC (the “Manager”), currently an indirect wholly owned subsidiary of Citigroup, would become an indirect wholly owned subsidiary of Legg Mason. The Manager is the investment adviser to the Fund.

The transaction is subject to certain regulatory approvals, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, Citigroup expects the transaction to be completed later this year.

Under the Investment Company Act of 1940, consummation of the transaction will result in the automatic termination of the investment advisory contract between the Fund and the Manager. Therefore, the Fund’s Board of Trustees will be asked to approve a new investment advisory contract between the Fund and the Manager. If approved by the Board, the new investment advisory contract will be presented to the shareholders of the Fund for their approval.

Information About Your Fund

As you may be aware, several issues in the mutual fund and variable annuity product industry have recently come under the scrutiny of federal and state regulators. The Travelers Insurance Company and some of its affiliates have received requests for information from various government regulators regarding market timing, late trading, fees, revenue sharing, producer compensation and other mutual fund and variable annuity product issues in connection with various inquiries and or investigations. The Travelers Insurance Company and its affiliates are responding to those information requests, but are not in a position to predict the outcome of these requests and investigations.

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

As always, thank you for your continued confidence in our stewardship of your assets. We look forward to helping you continue to meet your financial goals.

Sincerely,

R. Jay Gerken, CFA

Chairman, President and Chief Executive Officer

 Fund at a Glance (unaudited)

 Fund Expenses (unaudited)

          Example

      As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs and (2) ongoing costs, including management 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 January 1, 2005 and held for the six months ended June 30, 2005.

          Actual Expenses

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

(2)	Assumes reinvestment of dividends and capital gain distributions, if any, at net asset value. Total return is not annualized, as it may not be representative of the total return for the year. Total returns do not reflect expenses associated with the separate account such as administrative fees, account charges and surrender charges, which, if reflected, would reduce the total returns. Performance figures may reflect voluntary fee waivers and/or expense reimbursements. Past performance is no guarantee of future results. In the absence of voluntary fee waivers and/or expense reimbursements, the total return would have been lower.
(3)	Expenses are equal to the Fund’s annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 365.

 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. 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.

          1.     Organization and Significant Accounting Policies

      The Social Awareness Stock Portfolio (the “Fund”) is a separate diversified investment fund of The Travelers Series Trust (“Trust”). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. Shares of the Trust are offered exclusively for use with certain variable annuity and variable life insurance contracts offered through the separate accounts of various affiliated life insurance companies.

      The following are significant accounting policies consistently followed by the Fund. These policies 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. Equity securities for which market quotations are available are valued at the last sale price or official closing price on the primary market or exchange on which they trade. Debt securities are valued at the mean between the bid and asked prices provided by an independent pricing service that are based on transactions in debt obligations, quotations from bond dealers, market transactions in comparable securities and various relationships between securities. When prices are not readily available, or are determined not to reflect 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. Short-term obligations with maturities of 60 days or less are valued at amortized cost, which approximates market value.

      (b) Repurchase Agreements. When entering into repurchase agreements, it is the Fund’s policy that its custodian or a third party custodian takes possession of the underlying collateral securities, the market 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 market 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) Security Transactions and Investment Income. Security transactions are accounted for on a trade date basis. Interest income, adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. 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 determines the existence of a dividend declaration after exercising reasonable due diligence. The cost of investments sold is determined by use of the specific identification method.

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

      (e) Federal and Other Taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute substantially all of its taxable income and net realized gains on investments, if any, to shareholders each year. Therefore, no federal income tax provision is required in the Fund’s financial statements. Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

      (f) Reclassification. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share.

          2. Investment Advisory Agreement, Administration Agreement and Other Transactions with Affiliates

      Smith Barney Fund Management LLC (“SBFM”) acts as investment manager and adviser to the Fund. The Fund pays SBFM an investment management and advisory fee which is calculated daily and paid monthly at the annual rate of the Fund’s average daily net assets as follows:

	Investment
Average Daily Net Assets	Advisory Fee
First $50 million		0.650%
Next $50 million		0.550%
Next $100 million		0.450%
Over $200 million		0.400%

      The Travelers Insurance Company (“TIC”), an indirect wholly-owned subsidiary of Citigroup, acts as the Fund’s administrator. As compensation for its services, the Fund pays TIC an administration fee calculated at the annual rate of 0.06% of the Fund’s average daily net assets. This fee is calculated daily and paid monthly.

      TIC has entered into a Sub-Administrative Services Agreement with SBFM. TIC pays SBFM, as sub-administrator, a fee calculated at an annual rate of 0.02% of the average daily net assets of the Fund, plus $30,000, subject to a maximum of 0.06% of the Fund’s average daily net assets.

      During the six months ended June 30, 2005, the Fund had a contractual expense limitation in place of 1.25%. This expense limitation is renewed annually and can be terminated at any time by TIC with 60 days’ notice.

      Citigroup Trust Bank, fsb. (“CTB”), another subsidiary of Citigroup, acts as the Fund’s transfer agent. For the six months ended June 30, 2005, the Fund did not pay any transfer agent fees to CTB.

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

          3.     Investments

      During the six months ended June 30, 2005, the aggregate cost of purchases and proceeds from sales of investments (excluding short-term investments) were as follows:

Purchases	$	2,324,087
Sales		3,651,480

      At June 30, 2005, the aggregate gross unrealized appreciation and depreciation of investments for federal income tax purposes were substantially as follows:

Gross unrealized appreciation	$	19,793,316
Gross unrealized depreciation		(6,326,644	)
Net unrealized appreciation	$	13,466,672

          4.     Shares of Beneficial Interest

      The Declaration of Trust authorizes the issuance of an unlimited number of shares of beneficial interest without par value. Transactions in shares of the Fund were as follows:

	Six Months Ended			Year Ended
	June 30, 2005			December 31, 2004
Shares sold		180,917			708,617
Shares issued on reinvestment		115			27,780
Shares repurchased		(239,037	)		(332,976	)
Net Increase (Decrease)		(58,005	)		403,421

          5.     Capital Loss Carryforward

      As of December 31, 2004, the Fund had a net capital loss carryforward of $11,408,386, of which $1,710,995 expires in 2009, $8,136,777 expires in 2010, $1,560,614 expires in 2011. This amount will be available to offset like amounts of any future taxable capital gains.

          6.     Additional Information

      On May 31, 2005, the U.S. Securities and Exchange Commission (“SEC”) issued an order in connection with the settlement of an administrative proceeding against Smith Barney Fund Management LLC (“SBFM”) and Citigroup Global Markets Inc. (“CGMI”) relating to the appointment of an affiliated transfer agent for the Smith Barney family of mutual funds (the “Funds”), which includes the Fund (“TL&A Funds”).

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

      The SEC censured SBFM and CGMI and ordered them to cease and desist from violations of Sections 206(1) and 206(2) of the Advisers Act. The order requires Citigroup to pay $208.1 million, including $109 million in disgorgement of profits, $19.1 million in interest, and a civil money penalty of $80 million. Approximately $24.4 million has already been paid to the Funds, primarily through fee waivers. In addition, Travelers Life & Annuity and CAM reviewed the adequacy and accuracy of the disclosure provided to the TL&A Fund boards at the time the revised transfer agency arrangement was discussed with the boards and concluded that the transfer agency fees paid to CTB, for the period from June 1, 1999 to August 23, 2004, by the TL&A Funds that did not have expense caps in effect should be reimbursed with interest to the TL&A Funds. The reimbursement occurred on November 1, 2004.

      The remaining $183.7 million to be paid under the SEC order, including the penalty, has been paid to the U.S. Treasury and will be distributed pursuant to a plan to be prepared by Citigroup and submitted within 90 days of the entry of the order for approval by the SEC. The order also requires that transfer agency fees received from the Funds since December 1, 2004 less certain expenses be placed in escrow and provides that a portion of such fees may be subsequently distributed in accordance with the terms of the order.

17

 Notes to Financial Statements (unaudited) (continued)

      The order requires SBFM to recommend a new transfer agent contract to the Fund boards within 180 days of the entry of the order.

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

          7.     Other Matters

      On June 24, 2005, Citigroup announced that it has signed a definitive agreement under which Citigroup will sell substantially all of its worldwide asset management business to Legg Mason, Inc. (“Legg Mason”).

      As part of this transaction, SBFM (the “Manager”), currently an indirect wholly owned subsidiary of Citigroup, would become an indirect wholly owned subsidiary of Legg Mason. The Manager is the investment manager to the Fund.

      The transaction is subject to certain regulatory approvals, as well as other customary conditions to closing. Subject to such approvals and the satisfaction of the other conditions, Citigroup expects the transaction to be completed later this year.

      Under the 1940 Act, consummation of the transaction will result in the automatic termination of the investment management contract between the Fund and the Manager. Therefore, the Trust’s Board of Trustees will be asked to approve a new investment management contract between the Fund and the Manager. If approved by the Board, the new investment management contract will be presented to the shareholders of the Fund for their approval.

          8.     Subsequent Event

      On July 1, 2005, the Fund was merged into a newly created portfolio of the Travelers Series Fund. An affiliate of Citigroup. SBFM, which had been the investment adviser before the merger, was approved by shareholders as the investment adviser to the new portfolio after the merger.
