DEAR SHAREHOLDER,

The year 2003 marked the end of the three-year equity
bear market, with the resurgence of stocks of all sizes
and styles and from a variety of industries. However,
the greatest gains were made by small-cap, rather than
large-cap stocks, and by those whose stock price had
fallen the farthest since 2000's market peaks,
particularly technology stocks. In general, mid-cap
stocks performed better than large-caps, yet not as well
as small-caps. Although investment-grade bond
performance was quite subdued, many high yield and
convertible bonds soared. It is no coincidence that both
those bond sectors are heavily influenced by the
fortunes of the stock market.

The turning point for stocks came in mid-March as the
U.S. ended the uncertainty over the impending Iraq War
and the major combat came to a swift completion.
Meanwhile, historically low interest rates and lowered
income taxes provided a double economic stimulus, which
first raised expectations for economic growth and then
led to gains in consumer confidence and rapid expansion.
However, job growth remained sluggish, causing some
concerns over the sustainability of both the economic
rebound and the market's positive performance.

Within this environment, the fund performed as follows:

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.

The fund's returns reflect expenses incurred by the fund, but do not reflect any
charges or expenses imposed by the variable annuity or life contract you own,
and do not reflect the deduction of any taxes. Therefore, your actual returns
would have been lower. An investor may not invest directly in the fund.

Index returns are provided for comparison, but an investor cannot invest
directly in an index. Additionally, these returns do not reflect any deduction
for fees or expenses, as indices are unmanaged, and do not incur such expenses.
Index returns also do not reflect any deduction for taxes.

The Russell 1000 Value Index measures the performance of those Russell 1000
Index companies with lower price-to-book ratios and lower forecasted growth
values.

Lipper, Inc. is a major independent mutual-fund tracking organization. Returns
are based on the period ended December 31, 2003 and include the reinvestment of
dividends and capital gains, if any. Returns were calculated among the 89 funds
for the six-month period and among the 83 funds for the 12-month period in the
Lipper large-cap value variable funds category.

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 and
changes made to the portfolio during this time may have affected fund
performance.

INFORMATION ABOUT YOUR FUND

In recent months several issues in the mutual fund and variable insurance
products industries have come under the scrutiny of federal and state
regulators. Travelers Life & Annuity and some of its affiliates have received
requests for information from various government regulators regarding market
timing, late trading, and other mutual fund and variable product issues in
connection with various investigations. The fund has been informed that
Travelers Life & Annuity and its affiliates are responding to those information
requests and cooperating with the regulators but are not in a position to
predict the outcome of these requests and investigations.

                                                                               1


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,

/s/ R. Jay Gerken

                                MANAGER OVERVIEW

MFS VALUE PORTFOLIO

PERFORMANCE UPDATE

During its fiscal year ended December 31, 2003, the fund returned 24.61%. In
comparison, the fund underperformed both its benchmark, the unmanaged Russell
1000 Value Index(i), which returned 30.03% for the same period, and the Lipper
large cap value variable funds category, which returned 28.39% for the year.(1)

The fund's underperformance largely occurred in the first half of 2003, which
was a challenging market environment for our conservative, quality-focused style
when technology stocks and lower-quality stocks with weaker balance sheets led
stock market returns. With the release of second-quarter corporate earnings in
July 2003, market leadership began to expand to include a broader-based group of
economically-sensitive stocks such as basic materials, industrials, energy and
transportation (railroad) issues. As a result, the fund's returns improved
relative to the benchmark.

PORTFOLIO POSITIONING

The fund's sector positioning did not change significantly during the year.
However, we found opportunities to shift into what we believed were more
reasonably-valued companies within sectors where company fundamentals had
improved but stock prices had lagged the sector's leaders.

As has been the case for most of this year, the fund's relative performance was
most affected by its conservative positioning. Throughout the period, its
underweighting in autos and housing, technology, and financial stocks detracted
from performance. Our cautious positioning within the utility and leisure
sectors also hurt returns.

DETRACTORS FROM PERFORMANCE

Although the financial sector made the best contribution to absolute returns,
its underweighted position in the group caused relative returns to trail the
benchmark. For example, FLEETBOSTON FINANCIAL CORP., which was the object of a
takeover by BANK OF AMERICA CORP., made the strongest relative contribution to
returns. Investment bank, THE GOLDMAN SACHS GROUP, INC. provided strong returns
as the securities markets recovered and merger and acquisition activity
increased. The results from those two companies were somewhat offset by weaker,
yet still positive, returns from the FEDERAL NATIONAL MORTGAGE ASSOCIATION.

In the leisure sector, cable and publishing holdings such as VIACOM INC. and
TRIBUNE CO. experienced weaker-than-expected advertising revenues. Although the
price of both stocks rose, they lagged the sector. REED ELSEVIER PLC, which
publishes professional journals and textbooks, trailed other leisure stocks.
Investors were concerned about tight school budgets and weakness in advertising
revenues from its business-to-business publications.

Investors in auto stocks, in which the fund was underweighted, appeared to focus
their attention on improving auto sales. We continued to be concerned about U.S.
market share losses to overseas manufacturers, weak pricing, earnings quality,
and pension and health care liabilities.

The portfolio's cash position, which was held to buy new holdings and to cover
investor transfers or redemptions, also detracted from relative performance. In
a period when equity markets rose sharply, cash hurt performance against the
Russell 1000 Value, which has no cash position.

CONTRIBUTORS TO PERFORMANCE

Returns from CATERPILLAR INC., DEERE & CO., and EMERSON ELECTRIC CO. led
performance in the industrial goods and services sector. Rising commodity prices
combined with increased farm subsidies improved the outlook for spending on
agricultural equipment, benefiting Deere & Co. Also, restructuring initiatives
continue to drive improvements in margins and free cash flow. Strong quarterly
earnings reports and continued expectations for improved economic activity
helped move both Caterpillar and Emerson higher. The fund sold Caterpillar
before the end of the period when it reached our target price.

(1) Lipper, Inc. is a major independent mutual-fund tracking organization.
    Returns are based on the 12-month period ended December 31, 2003, calculated
    among the 83 funds in the Lipper large-cap value variable funds category
    including the reinvestment of dividends and capital gains, if any.
                                                                               3


Although technology continues to be a relatively small sector in the portfolio,
our holdings in this group provided strong absolute returns for the year.
Contributors within this group included semiconductor manufacturer TEXAS
INSTRUMENTS INC., networking solutions provider NORTEL NETWORKS CORPORATION,
semiconductor manufacturer INTEL CORPORATION, and electronic communications firm
MOTOROLA, INC. Improvements in telecommunications-related equipment sales also
helped to boost Texas Instruments' stock price. Nortel's stock rose sharply in
the third quarter when the company announced a number of new contracts with
large wireless companies such as VERIZON COMMUNICATIONS INC. and AT&T WIRELESS
SERVICES, INC.

Intel's stock price soared throughout the period when the company experienced
better-than-expected personal computer sales, positive earnings, and a generally
positive semiconductor environment. Motorola's stock price rose as a result of
an improved outlook for its handset sales and a more focused corporate strategy.
Texas Instruments, Nortel Networks, and Intel stock were sold when they achieved
our price objectives.

ALTRIA GROUP, INC, formerly Philip Morris, led the fund's consumer staples
holdings. The company continued to rebound from earlier concerns about
litigation and competitive pressures.

Thank you for your investment in the MFS Value Portfolio. We appreciate that you
have entrusted us to manage your money and value our relationship with you.

 ++ It is the opinion of the management that the Russell 1000 Value Index more

PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE. Investment return and
principal value of an investment will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

Average annual total returns are historical in nature and measure net investment
income and capital gain or loss from portfolio investments assuming
reinvestments of dividends. The total returns and graph presented above do not
reflect expenses associated with your variable contract such as administrative
fees, account charges and surrender charges which, if reflected, would reduce
the total returns for all periods shown.

 NOTES TO FINANCIAL STATEMENTS

     1.  SIGNIFICANT ACCOUNTING POLICIES

     MFS Value Portfolio ("Fund") is a separate 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, as a diversified, open-end
management investment company and consists of this fund and fifteen other
separate investment funds: Travelers Quality Bond, Lazard International Stock,
MFS Emerging Growth, Federated High Yield, Federated Stock, Disciplined Mid Cap
Stock, U.S. Government Securities, Social Awareness Stock, Pioneer Fund,
formerly known as Utilities, Large Cap, Equity Income, Convertible Securities,
Merrill Lynch Large Cap Core (formerly MFS Research), MFS Mid Cap Growth and
Zero Coupon Bond Fund Portfolio (Series 2005) Portfolios. 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 financial statements and financial highlights for
the other funds 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 mean between the bid and ask
prices; 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 asked 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 sales price; (c)
securities maturing within 60 days are valued at cost plus accreted discount or
minus amortized premium, which approximates value; (d) securities that have a
maturity of 60 days or more are valued at prices based on market quotations for
securities of similar type, yield and maturity; (e) interest income, adjusted
for amortization of premium and accretion of discount, is recorded on an accrual
basis and dividend income is recorded on the ex-dividend date; foreign dividends
are 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; (f) gains or losses on the sale of securities are calculated by
using the specific identification method; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; the Fund distributes
dividends and capital gains, if any, at least annually; (h) 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, income and expenses are translated
at the rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income or expense amounts recorded and collected
or paid are adjusted when reported by the custodian bank; (i) 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. At December 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
change; (j) the Fund intends to comply with the provisions 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 (k) 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.

     2.  INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS

     Travelers Asset Management International Company LLC ("TAMIC"), an indirect
wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), acts as investment
adviser to the Fund. The Fund pays TAMIC an investment advisory fee calculated
at the annual rate of 0.75% of the Fund's average daily net assets. This fee is
calculated daily and paid monthly.

     TAMIC has entered into a sub-advisory agreement with Massachusetts
Financial Services ("MFS"). Pursuant to the sub-advisory agreement, MFS is
responsible for the day-to-day portfolio operations and investment decisions for
the Fund. TAMIC pays MFS 0.375% of the Fund's average daily net assets.

     The Travelers Insurance Company ("TIC"), another indirect wholly-owned
subsidiary of Citigroup, acts as administrator to the Fund. The Fund pays TIC an
administration fee calculated at an 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 service agreement with
                                                                              13


- --------------------------------------------------------------------------------
 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Smith Barney Fund Management LLC ("SBFM"), another indirect wholly-owned
subsidiary of Citigroup. TIC pays SBFM, as sub-administrator, a fee calculated
at an annual rate of 0.02% of the Fund's average daily net assets, plus $30,000,
subject to a maximum of 0.06% of the Fund's average daily net assets.

     For the year ended December 31, 2003, the Fund had a voluntary expense
limitation in place of 1.00%. As a result, TIC has agreed to reimburse the Fund
for expenses in the amount of $26,185. This expense limitation can be terminated
at any time by TIC.

     Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as
the Fund's transfer agent. CTB receives account fees and asset-based fees that
vary according to the size and type of account. For the year ended December 31,
2003, the Fund paid transfer agent fees of $5,000 to CTB.

     For the year ended December 31, 2003, Citigroup Global Markets Inc.
(formerly known as Salomon Smith Barney Inc.), another indirect wholly-owned
subsidiary of Citigroup, did not receive any brokerage commissions.

     One Trustee and all officers of the Trust are employees of Citigroup or its
affiliates.

     3.  INVESTMENTS

     During the year ended December 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:

<Table>
                                                           
- -------------------------------------------------------------------------
Purchases...................................................  $20,233,623
Sales.......................................................   18,634,199
- -------------------------------------------------------------------------
</Table>

     At December 31, 2003, aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

<Table>

Gross unrealized depreciation...............................    (277,062)
- ------------------------------------------------------------------------
Net unrealized appreciation.................................  $4,628,608
- ------------------------------------------------------------------------
</Table>

     4.  FORWARD FOREIGN CURRENCY CONTRACTS

     The Fund from time to time may enter into 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 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.

     At December 31, 2003, the Fund did not have any open forward foreign
currency contracts.

     5.  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:

     At December 31, 2003, the Fund had, for Federal income tax purposes,
approximately $1,701,000 of unused capital loss carryforwards available to
offset future capital gains. To the extent that these carryforward losses are
used to offset capital gains, it is probable that the gains so offset will not
be distributed.

     8.  ADDITIONAL INFORMATION

     The Fund has received the following information from Citigroup Asset
Management ("CAM"), the Citigroup business unit which includes the Fund's
Investment Manager, an indirect wholly-owned subsidiary 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 its 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 approximately $17 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.

                                                                              15

    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 be reduced.

auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the

                  described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.
                  The Audit Committee ("Committee") has adopted policies and
                  procedures to, among other purposes, approve all audit and
                  non-audit services provided to the Registrant and certain
                  other persons by the Registrant's independent auditors.

                  The Committee shall not approve non-audit services that the
                  Committee believes may taint 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.

                  The policies and procedures require the Committee to approve
                  (a) all audit and permissible non-audit services to be
                  provided to the Registrant 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 Registrant. In carrying out this
                  responsibility, the Committee shall seek periodically from the
                  Adviser and from the independent auditors a list of audit and
                  permissible non-audit services that can be expected to be
                  rendered to the Registrant, the Adviser or any Covered Service
                  Providers by the Registrant's independent auditors, and an
                  estimate of the fees sought to be paid in connection with such
                  services. The Committee may delegate its responsibility to
                  approve any such audit and permissible non-audit services to a
                  sub-committee consisting of the Chairperson of the Committee
                  (the "Chairperson") and at least one other member of the
                  Committee, as the Chairperson, from time to time, may
                  determine and appoint, and such sub-committee shall report to
                  the Committee, at its next meeting after the sub-committee's
                  meeting, its decision(s). From year to year, and at such other
                  times as the Committee deems appropriate, the Committee shall
                  report to the Board whether this system of approval has been
                  effective and efficient or whether this Charter should be
                  amended to allow for pre-approval pursuant to such policies
                  and procedures as the Committee shall approve, including the
                  delegation of some or all of the Committee's per-approval
                  responsibilities to other persons (other than the Adviser or
                  the Fund's officers).

                  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
                  by (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.

         (f)      N/A

         (g)      Non-audit fees billed - $100,000 and $1.2 million for the
                  years ended 12/31/2003 and 12/31/2002.

         (h)      Yes. Travelers Series Trust'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 Travelers Series Trust or to Service
                  Affiliates which were required to be pre-approved were
                  pre-approved as required.

ITEM 9.  CONTROLS AND PROCEDURES.

         (a)      The registrant's principal executive officer and principal
                  financial officer have concluded that the registrant's
                  disclosure controls and procedures (as defined in Rule 30a-
                  3(c) under the Investment Company Act of 1940, as amended (the
                  "1940 Act")) are effective as of a date within 90 days of the
                  filing date of this report that includes the disclosure
                  required by this paragraph, based on their evaluation of the
                  disclosure controls and procedures required by Rule 30a-3(b)
                  under the 1940 Act and 15d-15(b) under the Securities Exchange
                  Act of 1934.

         (b)      There were no changes in the registrant's internal control
                  over financial reporting (as defined in Rule 30a-3(d) under
                  the 1940 Act) that occurred during the registrant's last
                  fiscal half-year (the registrant's second fiscal half-year in
                  the case of an annual report) that have materially affected,
                  or are likely to materially affect the registrant's internal
                  control over financial reporting.
