DEAR SHAREHOLDER,

The philosopher Bertrand Russell famously remarked that,
"Change is one thing, progress is another." 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 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. Jay Gerken, CFA
Chairman, President and Chief Executive Officer

 BOND RATINGS (UNAUDITED)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to
"BBB" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

<Table>
    
AAA  --   Bonds rated "AAA" have the highest rating assigned by
          Standard & Poor's to a debt obligation. Capacity to pay
          interest and repay principal is extremely strong.
AA   --   Bonds rated "AA" have a very strong capacity to pay interest
          and repay principal and differ from the highest rated issues
          only in small degree.
A    --   Bonds rated "A" have a strong capacity to pay interest and
          repay principal although they are somewhat more susceptible
          to the adverse effects of changes in circumstances and
          economic conditions than bonds in higher rated categories.
BBB  --   Bonds rated "BBB" have an adequate capacity to pay interest
          and repay principal. Whereas they normally exhibit adequate
          protection parameters, adverse economic conditions or
          changing circumstances are more likely to lead to a weakened
          capacity to pay interest and repay principal for bonds in
          this category than in higher rated categories.

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

     1.  SIGNIFICANT ACCOUNTING POLICIES

     The Zero Coupon Bond Fund Portfolio Series 2005 ("Fund"), a separate
investment fund of The Travelers Series Trust ("Trust"), 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: U.S. Government Securities,
Social Awareness Stock, Pioneer Fund, formerly known as Utilities, Travelers
Quality Bond, Lazard International Stock, MFS Emerging Growth, Federated High
Yield, Federated Stock, Large Cap, Equity Income, Disciplined Mid Cap Stock,
Convertible Securities, MFS Research, MFS Mid Cap Growth and MFS Value
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;
securities for which no sales prices were reported and U.S. government agencies
and obligations are valued at the mean between the last reported bid and ask
prices or on the basis of quotations received from reputable brokers or other
recognized sources; (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; (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 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; (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; and (j) 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 an annual rate of 0.10% of its average daily net assets. This fee is
calculated daily and paid monthly.

     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 its average daily
net assets. This fee is calculated daily and paid monthly. TIC has entered into
a sub-administrative service agreement with Smith Barney Fund Management LLC
("SBFM"). TIC pays SBFM, as sub-administrator, a fee calculated at an annual
rate of 0.06% of the Fund's average daily net assets.

     For the six months ended June 30, 2003, TIC has agreed to reimburse the
Fund for expenses in the amount of $32,054.

     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. During the six months ended June
30, 2003, the Fund paid transfer agent fees of $2,500 to CTB.

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

     3.  INVESTMENTS

     During the six months ended June 30, 2003, there were no purchases or
sales.

     At June 30, 2003, the aggregate unrealized appreciation and depreciation of
investments for Federal income tax purposes were substantially as follows:

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

     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.  STRIPPED SECURITIES

     The Fund invests primarily in "Stripped Securities," a term used
collectively for Stripped Treasury Securities, Stripped Government Securities,
Stripped Corporate Securities, and Stripped Eurodollar Obligations; as well as
other stripped securities. Stripped securities can be securities consisting of
debt obligations that have been stripped of unmatured interest coupons,
securities consisting of unmatured interest coupons that have been stripped from
debt obligations, or debt obligations that are issued without interest coupons
and are sold at substantial discounts from their face amounts.

     Stripped Securities do not make periodic payments of interest prior to
maturity. The market value of Stripped Securities will fluctuate in response to
changes in economic conditions, interest rates and the market's perception of
the securities. Fluctuations in response to interest rates may be greater than
those for debt obligations of comparable maturities that pay interest currently.
The amount of fluctuation increases with a longer period of maturity.

     6.  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:
