DEAR SHAREHOLDER,

Despite sharply rising oil prices, threats of terrorism,
geopolitical concerns and uncertainties surrounding the
presidential election, the U.S. economy continued to
expand during the reporting period. Following a robust
4.5% gain in the first quarter of 2004, gross domestic
product ("GDP")(i) growth was 3.3% in the second quarter
of the year. This decline was largely attributed to
higher energy prices. However, third quarter 2004 GDP
rose a strong 4.0%. While fourth quarter GDP figures
have not yet been released, continued growth is
expected.

Turning to the financial markets, stocks in both the
U.S. and abroad rallied sharply during the fourth
quarter of 2004, helping to produce solid gains for the
year. With the uncertainty of the presidential election
behind them, coupled with falling oil prices, investors
were drawn to the equity markets. The overall bond
market also generated positive returns during the fiscal
year. This was surprising to many, given the economic
expansion and five interest rate hikes by the Federal
Reserve Board ("Fed").(ii)

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 may have affected
fund performance.

INFORMATION ABOUT YOUR FUND

As you may be aware, several issues in the mutual fund and variable product
industry have recently 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, fees, revenue sharing, producer compensation 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, but are not in a position to predict the outcome of
these requests and investigations.

As previously disclosed by Citigroup, the Staff of the Securities and Exchange
Commission ("SEC") has notified Citigroup Asset Management ("CAM") and Citicorp
Trust Bank ("CTB"), an affiliate of CAM, that the Staff is considering
recommending a civil injunctive action and/or an administrative proceeding
against CAM, CTB, the former CEO of CAM, two former employees and a current
employee of CAM, relating to the creation, operation and fees of an internal
transfer agent unit that serves various CAM-managed funds. Citigroup is
cooperating with the SEC and will seek to resolve this matter in discussion with
the SEC Staff. Although there can be no assurance, Citigroup does not believe
that this matter will have a material adverse effect on the fund. For further
information, please see the "Additional Information" note in the Notes to the
Financial Statements included in this report.

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

ZERO COUPON BOND FUND PORTFOLIO SERIES 2005

MARKET/ECONOMIC OVERVIEW

The economic expansion entered its fourth year at the close of 2004. Led by
strong consumer and business demand, the balance of growth was quite healthy.
The employment picture improved during the year, as rising profits led to
increased corporate willingness to hire new employees. Strong consumer and
business fundamentals appear likely to continue into 2005 and consumer spending
looks to strengthen further relative to last year.

Inflation began to rise modestly in 2004 as shortages of certain goods and
commodities developed around the world. In 2005, inflation pressures look to
rise as healthy growth continues to improve corporate pricing power. The ongoing
economic recovery and rising price pressures caused the Fed to institute a
series of five 25 basis point(iii) rate hikes, beginning in mid-2004. This trend
looks to continue well into 2005. After the end of the fund's reporting period,
at their February meeting, the Fed once again raised the target rate by 0.25% to
2.50%.

PERFORMANCE UPDATE(1)

For the twelve months ended December 31, 2004, the Zero Coupon Bond Fund
Portfolio Series 2005 returned 1.06%. In comparison, a U.S. Treasury STRIP
maturing on November 15, 2005,(iv) which is similar to securities in the fund,
returned 0.99% during the same time period. In comparison, the fund's unmanaged
benchmark, the Merrill Lynch Zero Coupon 10-Year Index(v) returned 7.03%, and
the Lipper Variable Target Maturity Funds Category Average was 3.05% for the
same period.(2)

     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.

     PERFORMANCE FIGURES MAY REFLECT REIMBURSEMENTS AND/OR FEE WAIVERS,
     WITHOUT WHICH THE PERFORMANCE WOULD HAVE BEEN LOWER.

     FUND RETURNS ASSUME THE REINVESTMENT OF INCOME DIVIDENDS AND CAPITAL
     GAINS DISTRIBUTIONS AT NET ASSET VALUE AND THE DEDUCTION OF ALL FUND
     EXPENSES.

     Lipper, Inc. is a major independent mutual-fund tracking organization.
     Returns are based on the period ended December 31, 2004 and include
     the reinvestment of dividends and capital gains, if any. Returns were
     calculated among the 9 funds for the six-month period and among the 9
     funds for the 12-month period in the variable target maturity funds

     category.

(1) The fund is an underlying investment option of various variable annuity and
    variable life products. The fund's performance returns do not reflect the
    deduction of initial sales charges and expenses imposed in connection with
    investing in variable annuity or variable life 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 12-month period ended December 31, 2004, including
    the reinvestment of dividends and capital gains, if any, calculated among
    the 9 funds in the fund's Lipper category.

As the fund is scheduled to mature in December 2005 (please see special note
below), it is primarily invested in short-term U.S. Treasury STRIPS. Because of
the short-term nature of the fund's holdings, the fund underperformed its
benchmark indices, which are composed of longer-term holdings.

CONTRIBUTORS TO PERFORMANCE

As of December 31, 2004, the effective duration of the portfolio was 1.11 years.
During the fiscal year, the yield curve(vi) flattened as short and intermediate
term rates increased more than longer-term rates. The portfolio had less
exposure to the negative effects of these rising interest rate moves. The fund's
short-term cash position benefited results, as the yield it earned continued to
increase in the rising rate environment.

Thank you for your investment in the Zero Coupon Bond Fund Portfolio Series
2005. As ever, we appreciate that you have chosen us to manage your assets and
we remain focused on achieving the fund's investment goals.

Sincerely,

 FUND EXPENSES (UNAUDITED)

     EXAMPLE

     As a shareholder of the Fund, you may incur two types of costs: (1)
transaction costs, including front-end and back-end sales charges (loads) on
purchase payments, reinvested dividends, or other distributions; and (2) ongoing
costs, including management fees; distribution and/or service (12b-1) 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 July 1, 2004
and held for the six months ended December 31, 2004.

     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."

</Table>

(1) For the six months ended December 31, 2004.
(2) Assumes reinvestment of dividends and capital gains 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 (net of expense reimbursement and/or voluntary fee waiver) 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 366.

                                                                               5


- --------------------------------------------------------------------------------
 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,
such as front-end or back-end sales charges (loads). 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.

Treasury zero coupon bond with a maturity date that is similar to
those in the Portfolio. The Merrill Lynch Zero Coupon 10-Year Index
is comprised of U.S. Government stripped securities which have a
maturity not greater than ten years.

Assumes reinvestment of all dividends and capital gain distributions, if any, at
net asset value. All figures represent past performance and are not a guarantee
of future results. 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. The graph does 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. In the absence
of voluntary fee waivers and/or expense reimbursements, the total return would
have been lower.

(1) Per share amounts have been calculated using the monthly average shares
    method.
(2) Total returns 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. 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) Travelers Insurance Company has agreed to reimburse the fund for certain
    expenses for the years ended December 31, 2004, 2003, 2002, 2001 and 2000
    respectively. In addition, Smith Barney Fund Management LLC voluntarily
    waived a portion of its fee for the year ended December 31, 2004. If such
    expenses were not reimbursed and/or fees not voluntarily waived, actual
    expense ratios would have been 1.62%, 1.16%, 1.27%, 1.28% and 1.44%,
    respectively.
(4) As a result of an expense limitation, the ratio of expenses to average net
    assets will not exceed 0.15%.

 NOTES TO FINANCIAL STATEMENTS

     1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     The Zero Coupon Bond Fund Portfolio Series 2005 ("Fund"), a separate
diversified investment fund of The Travelers Series Trust ("Trust"), a
Massachusetts business trust, is registered under the Investment Company Act of
1940, as amended, 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.

     In accordance with its prospectus, the Fund will liquidate in December
2005. Accounting rules require that financial statements for entities in
liquidation, or for which liquidation appears imminent, be prepared on a
liquidation basis of accounting. As U.S. generally accepted accounting
principles ("GAAP") for investment companies are materially consistent with the
liquidation basis of accounting, the financial statements have been prepared in
conformity with GAAP for investment companies.

     The following are significant accounting policies consistently followed by
the Fund and are in conformity with 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.  Securities traded on national securities markets
are valued at the closing price 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.
Short-term obligations with maturities of 60 days or less are valued at
amortized cost, which approximates value.

     (B) REPURCHASE AGREEMENTS.  When entering into repurchase agreements, it is
the Fund's policy that a custodian takes possession of the underlying collateral
securities, the 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 value of the collateral declines of 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) 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. 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.

     (D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  Security transactions are
accounted for on a trade date basis. Interest income is recorded on the accrual
basis. The cost of investments sold is determined by use of the specific
identification method.

     (E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends from net
investment income and distributions of net realized gains to shareholders of the
Fund, if any, are declared at least annually. Dividends and 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.

     (F) 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.

     (G) RECLASSIFICATION.  GAAP requires that certain components of net assets
be adjusted to reflect permanent differences between financial and tax
reporting. Accordingly, during the current year, $364 has been reclassified
between paid-in capital and overdistributed net investment income, as a result
of permanent differences attributable to a taxable overdistribution of net
investment income. This reclassification has no effect on net assets or net
asset values per share.

                                                                              13

     6.  ADDITIONAL INFORMATION

     In connection with an investigation previously disclosed by Citigroup, the
Staff of the Securities and Exchange Commission ("SEC") has notified Citigroup
Asset Management ("CAM"), the Citigroup business unit that includes the funds'
investment manager and other investment advisory companies; Citicorp Trust Bank
("CTB"), an affiliate of CAM; Thomas W. Jones, the former CEO of CAM; and three
other individuals, one of whom is an employee and two of whom are former
employees of CAM, that the SEC Staff is considering recommending a civil
injunctive action and/or an administrative proceeding against each of them
relating to the creation and operation of an internal transfer agent unit to
serve various CAM-managed funds.

     In 1999, CTB entered the transfer agent business. CTB hired an unaffiliated
subcontractor to perform some of the transfer agent services. The subcontractor,
in exchange, had signed a separate agreement with CAM in 1998 that guaranteed
investment management revenue to CAM and investment banking revenue to a CAM
affiliate. The subcontractor's business was later taken over by PFPC Inc., and
at that time the revenue guarantee was eliminated and a one-time payment was
made by the subcontractor to a CAM affiliate.

     CAM did not disclose the revenue guarantee when the boards of various
CAM-managed funds hired CTB as transfer agent. Nor did CAM disclose to the
boards of the various CAM-managed funds the one-time payment received by the CAM
affiliate when it was made. As previously disclosed, CAM has already paid the
applicable funds, primarily through voluntary fee waivers, a total of
approximately $17 million (plus interest), which is the amount of the revenue
received by Citigroup relating to the revenue guarantee.

     In addition, the SEC Staff has indicated that it is considering
recommending action based on the adequacy of the disclosures made to the fund
boards that approved the transfer agency arrangement, CAM's initiation and
operation of, and compensation for, the transfer agent business and CAM's
retention of, and agreements with, the subcontractor.

     Citigroup is cooperating fully in the SEC's investigation and is seeking to
resolve the matter in discussions with the SEC Staff. On January 20, 2005,
Citigroup stated that it had established an aggregate reserve of $196 million
($25 million in the third quarter of 2004 and $171 million in the fourth quarter
of 2004) related to its discussions with the SEC Staff. Settlement negotiations
are ongoing and any settlement of this matter with the SEC will require approval
by the Citigroup Board and acceptance by the Commission.

     Unless and until any settlement is consummated, there can be no assurance
that any amount reserved by Citigroup will be distributed. Nor is there at this
time any certainty as to how the proceeds of any settlement would be
distributed, to whom any such distribution would be made, the methodology by
which such distribution would be allocated, and when such distribution would 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.  SUBSEQUENT EVENT NOTE

     On January 31, 2005, Citigroup announced that it has reached an agreement
with MetLife, Inc. ("MetLife") to sell Citigroup's life insurance and annuity
businesses ("Travelers Life & Annuity") to MetLife. As part of this transaction,
TAMIC, currently an indirect wholly owned subsidiary of Citigroup, would become
an indirect wholly owned subsidiary of MetLife. TAMIC is the investment adviser
to Zero Coupon Bond Fund Portfolio Series 2005.

     The transaction is subject to certain regulatory approvals, as well as
other customary conditions to closing. The transaction is expected to close this
summer.

     In connection with this transaction, the Trust's Board of Trustees will be
asked to approve new investment advisory and administrative services contracts,
and, to the extent required by law, variable annuity and variable life contract
owners, who beneficially own the shares of the funds, will be asked to approve
new investment advisory agreements.

                                                                              15

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
THE TRAVELERS SERIES TRUST:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Zero Coupon Bond Fund Portfolio Series 2005 of
The Travelers Series Trust ("Trust") as of December 31, 2004, and the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the years in the two-year period then ended and the
financial highlights for each of the years in the five-year period then ended.
These financial statements and financial highlights are the responsibility of
the Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). 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 December 31, 2004, by correspondence with the custodian
and broker. 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 Zero
Coupon Bond Fund Portfolio Series 2005 of The Travelers Series Trust as of
December 31, 2004, 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 the financial highlights for each of the years in the five-year
period then ended, in conformity with U.S. generally accepted accounting
principles.

      (e)   (1) Audit Committee's pre-approval policies and procedures
         described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

         The Charter for the Audit Committee (the "Committee") of the Board of
         each registered investment company (the "Fund") advised by Smith Barney
         Fund Management LLC or Salomon Brothers Asset Management Inc or one of
         their affiliates (each, an "Adviser") requires that the Committee shall
         approve (a) all audit and permissible non-audit services to be provided
         to the Fund 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 Fund. The Committee may implement
         policies and procedures by which such services are approved other than
         by the full Committee.

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

         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 to (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.

         (2) For The Travelers Series Trust, the percentage of fees that were
         approved by the audit committee, with respect to: Audit-Related Fees
         were 100% and 100% for the years ended 12/31/04 and 12/31/03; Tax Fees
         were 100% and 100% for the years ended 12/31/04 and 12/31/03; and Other
         Fees were 100% and 100% for the years ended 12/31/04 and 12/31/03.

      (f)    N/A

      (g)    Non-audit fees billed by the Accountant for services rendered to
         Travelers Series Trust and CAM and any entity controlling, controlled
         by, or under common control with CAM that provides ongoing services to
         Travelers Series Trust. Fees billed to and paid by Citigroup Global
         Markets, Inc. related to the transfer agent matter as fully described
         in the notes to the financial statements titled "additional
         information" were $75,000 and $0 for the years ended 12/31/04 and
         12/31/03.

      (h)    Yes. The 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.

                  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.
