EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2003
MANAGEMENT DISCUSSION

Eaton Vance VT Floating-Rate Income Fund had a total return of 2.93% for the
year ended December 31, 2003.(1) That return was the result of shareholder
distributions from net investment income of $0.222 per share and an increase in
net asset value per share from $10.00 on December 31, 2002 to $10.07 on December
31, 2003. Based on the Fund's closing net asset value per share of $10.07 at
December 31, 2003 the Fund had a distribution rate of 1.94%.(2) The Fund's SEC
30-day yield at December 31 was 2.13%.(3)

AN INTERVIEW WITH SCOTT H. PAGE AND PAYSON F. SWAFFIELD, CO-PORTFOLIO MANAGERS
OF EATON VANCE VT FLOATING-RATE INCOME FUND.

Q: SCOTT, HOW WOULD YOU DESCRIBE THE LOAN MARKET DURING THE PAST YEAR?

A: MR. PAGE: The loan market has benefited from a stronger economy.
   Long-beleaguered industrial and technology companies have begun - at last -
   to see an increase in orders in response to a renewal of capital spending. In
   addition, companies that cut costs and restructured their debt during the
   economic slowdown are now beginning to see the benefits of those moves, as
   business activity appears to be gathering steam. Finally, consumer and
   investor confidence has increased, as corporate governance issues are being
   addressed by regulators and businesses alike. Together, these trends
   contributed to a better credit climate and a stronger loan market during
   2003.

PAYSON F. SWAFFIELD

Q: PAYSON, HOW WOULD YOU CHARACTERIZE THE FUND'S PERFORMANCE IN THIS
   ENVIRONMENT?

A: MR. SWAFFIELD: The Fund posted a positive total return in the fiscal year
   ended December 31, 2003. In a low interest rate environment, the Fund
   outperformed most short-term investment vehicles. The Fund underperformed its
   benchmark, the CSFB Leveraged Loan Index.(4) That underperformance was the
   result of a lower exposure to the telecom and technology areas, which staged
   a recovery after having performed very poorly in previous years. While the
   inclusion of these sectors might provide a short-term boost, we believe they
   represent an added risk if the markets were to suffer a reversal. Despite the
   current market's greater tolerance for risk, we continue to apply the same
   credit standards that created lower volatility and downside during the
   difficult credit markets of 2000, 2001 and 2002.

MUTUAL FUND SHARES ARE NOT INSURED BY THE FDIC AND ARE NOT DEPOSITS OR OTHER
OBLIGATIONS OF, OR GUARANTEED BY, ANY DEPOSITORY INSTITUTION. SHARES ARE SUBJECT
TO INVESTMENT RISKS, INCLUDING POSSIBLE LOSS OF PRINCIPAL INVESTED.

(1) Returns are historical and are calculated by determining the percentage
    change in net asset value with all distributions reinvested. There is no
    sales charge. Insurance-related charges are not included in calculations of
    returns. Please refer to the report for your insurance contract for
    performance data reflecting insurance-related charges.

(2) The Fund's distribution rate represents actual distributions paid to
    shareholders and is calculated daily by dividing the last distribution per
    share (annualized) by the net asset value.

(3) The Fund's SEC yield is calculated by dividing the net investment income per
    share for the 30-day period by the offering price at the end of the period
    and annualizing the result.

(4) The CSFB Leveraged Loan Index is a representative index of tradable, senior,
    secured, U.S. dollar-denominated leveraged loans. It is not possible to
    invest in an Index.

    Past Performance is no guarantee of future results. Investment return and
    principal value will fluctuate so that shares, when redeemed, may be worth
    more or less than their original cost. Performance is for the stated time
    period only; due to market volatility, the Fund's current performance may be
    different.

                                        1
<Page>

   It's important to note that the Fund's performance has historically been
   characterized by low volatility, due in part to our strict investment
   standards.

Q: HOW HAVE YOU POSITIONED THE FUND IN RECENT MONTHS?

A: MR. PAGE: We continued our efforts at diversification across industry
   sectors.(1) The Fund had an exposure to the expanding economy - including the
   publishing and printing, manufacturing and retail sectors - as well as to
   non-GDP-sensitive areas - such as food, cable television and health care. The
   Fund included 120 borrowers across 35 industries, with no sector larger than
   8% of the Fund. From a sector standpoint, publishing and printing was the
   Fund's largest weighting, at 7.7%, followed by food, beverages and tobacco,
   at 7.5%; broadcast media, at 5.8%; retail - specialty, at 4.1%; and health
   care providers and services, at 4.1%.(2)

   During the period, we maintained our conservative investment criteria,
   demanding what we believe to be good collateral and adequate cash flow.
   Adhering to strict investment standards has historically served the Fund well
   in both strong and weak economic scenarios.

Q: A STRONGER ECONOMY INCREASES THE LIKELIHOOD OF HIGHER INTEREST RATES. HOW
   DOES THE LOAN MARKET VIEW THAT PROSPECT?

A: MR. PAGE: Floating-rate loans are unique in that they have historically
   rewarded investors in a rising rate environment. Loans have reset provisions,
   which means they can be adjusted periodically in response to changes in the
   underlying rate environment. Generally, loan interest rates are reset every
   50-70 days to reflect movements in the London-Interbank Offered Rate (LIBOR),
   which is the principal base rate for the Fund.

   A relatively short days-to-reset average gives us the flexibility of being
   able to adjust fairly rapidly to changing interest rates. In a rising rate
   climate, that represents a major advantage over fixed-rate bonds. While loan
   interest rates are generally adjusted upward as rates rise, fixed-rate bond
   interest rates remain the same, and are therefore more subject to interest
   rate risk.

Q: YOU INDICATED THAT THE PORTFOLIO HAD AN EXPOSURE TO THE GROWING ECONOMY.
   COULD YOU EXPAND ON THAT THEME?

A: MR. SWAFFIELD: Yes. Among its largest holdings, the Portfolio had investments
   in companies that we believe are likely to be direct beneficiaries of an
   economic recovery. One such sector was publishing and printing. The Fund had
   investments in several newspaper companies. Overall, this is a sector that
   held up very well during the economic downturn in 2001-2002 and has
   historically benefited from an economic recovery. The Trust had several
   investments in newspaper companies whose revenues are based on local
   advertising expenditures. Local ad spending has tended to be more stable in
   economic downturns than national advertising. In addition, newspaper
   companies have benefited from a consolidation trend within the sector, with
   larger chains buying smaller newspaper companies.

        (1) The Fund is a non-diversified investment.
        (2) Sector weightings are subject to change.

                                        2
<Page>

   Elsewhere in the cyclical part of the economy, container and packaging
   companies should see higher demand. The uptrend within the manufacturing
   sector has increased the need for packaging materials used in shipping goods.

Q: DID THE FUND INVEST IN NON-ECONOMICALLY-SENSITIVE SECTORS?

A: MR. PAGE: Yes. The Fund had investments in sectors such as health care and
   food and beverages, areas where growth has historically been generally less
   dependent on the fluctuations in the economy. In the health care sector, the
   Fund had an investment in a nationwide operator of acute care hospitals. The
   company operates 63 facilities in 22 states, primarily in non-urban areas,
   where it is typically the primary health care facility. The company offers a
   broad range of inpatient and outpatient medical services.

   In the food and beverages area, the Fund had investments in a range of
   companies, including household name food producers, the largest U.S. producer
   of egg products, a national pizza chain, and a major soft drink producer.

Q: WERE THERE ANY SECTORS WHOSE PERFORMANCE IMPEDED THE FUND'S PERFORMANCE?

A: MR. SWAFFIELD: There were no sectors that specifically hurt the Fund's
   performance. However, as I indicated previously, the Fund underperformed its
   benchmark during the year due to its underweighting in the technology and
   telecom sectors. Those sectors declined sharply during last year's market
   decline and, not surprisingly, rebounded more dramatically than the broad
   market as the economy recovered in 2003.

(1) Senior floating-rate interests often require prepayments from excess cash
    flows or permit the borrower to repay at its election. The degree to which
    borrowers repay, whether as a contractual requirement or at their election,
    cannot be predicted with accuracy. As a result, the actual remaining
    maturity may be substantially less than the stated maturities shown.
    However, it is anticipated that the senior floating-rate interests will have
    an expected average life of approximately two to four years.

Note: At December 31, 2003, the Trust had unfunded commitments amounting to
$370,000 under various revolving credit agreements.

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2003
NOTES TO FINANCIAL STATEMENTS

1  SIGNIFICANT ACCOUNTING POLICIES

   Eaton Vance VT Floating-Rate Income Fund (the Fund) is a non-diversified
   series of Eaton Vance Variable Trust (the Trust). The Trust, which was
   organized under Massachusetts law on August 14, 2000, is an entity of the
   type commonly known as a Massachusetts business trust and is registered
   undera the Investment Company Act of 1940, as amended, as an open-end
   management investment company. The Fund seeks to provide a high level of
   current income by investing primarily in senior secured floating rate loans.
   The following is a summary of significant accounting policies consistently
   followed by the Fund in the preparation of its financial statements. The
   policies are in conformity with accounting principles generally accepted in
   the United States of America.

   A INVESTMENT VALUATIONS -- The investments of the Fund are primarily in
   interests in Senior Floating-rate loans (Senior Loans). Certain senior loans
   are deemed to be liquid if reliable market quotations are readily available
   for them. Liquid senior loans are valued on the basis of prices furnished by
   a pricing service. Eaton Vance Management (EVM) values liquid Senior Loans on
   the basis of prices furnished by one or more pricing services. Other Senior
   Loans are valued at fair value by the Fund's investment advisor, EVM, under
   procedures established by the Trustees as permitted by Section 2(a)(41) of
   the Investment Company Act of 1940. Such procedures include the consideration
   of relevant factors, data and information relating to fair value, including
   (i) the characteristics of and fundamental analytical data relating to the
   Senior Loan, including the cost, size, current interest rate, period until
   next interest rate reset, maturity and base lending rate of the Senior Loan,
   the terms and conditions of the Senior Loan and any related agreements, and
   the position of the Senior Loan in the Borrower's debt structure; (ii) the
   nature, adequacy and value of the collateral, including the Fund's rights,
   remedies and interests with respect to the collateral; (iii) the
   creditworthiness of the Borrower, based on an evaluation of its financial
   condition, financial statements and information about the Borrower's
   business, cash flows, capital structure and future prospects; (iv)
   information relating to the market for the Senior Loan including price
   quotations for and trading in the Senior Loan, and interests in similar
   Senior Loans and the market environment and investor attitudes towards the
   Senior Loan and interests in similar Senior Loans; (v) the reputation and
   financial condition of the agent and any intermediate participant in the
   Senior Loan; and (vi) general economic and market conditions affecting the
   fair value of the Senior Loan. Portfolio securities (other than short-term
   obligations, but including listed issues) may be valued on the basis of
   prices furnished by one or more pricing services which determine prices for
   normal, institutional-size trading units of such securities which may use
   market information, transactions for comparable securities and various
   relationships between securities which are generally recognized by
   institutional traders. In certain circumstances, portfolio securities will be
   valued at the last sales price on the exchange that is the primary market for
   such securities, or the last quoted bid price for those securities for which
   the over-the-counter market is the primary market or for listed securities in
   which there were no sales during the day. The value of interest rate swaps
   will be determined in accordance with a discounted present value formula and
   then confirmed by obtaining a bank quotation. Short-term obligations which
   mature in sixty days or less are valued at amortized cost, if their original
   term to maturity when acquired by the Fund was 60 days or less or are valued
   at amortized cost using their value on the 61st day prior to maturity, if
   their original term to maturity when acquired by the Fund was more then 60
   days, unless in each case this is determined not to represent fair value.
   Repurchase agreements are valued at cost plus accrued interest. Other
   portfolio securities for which there are no quotations or valuations are
   valued at fair value as determined in good faith by or on behalf of the
   Trustees.

   B INCOME -- Interest income from Senior Loans is recorded on the accrual
   basis at the then-current interest rate, while all other interest income is
   determined on the basis of interest accrued, adjusted for amortization of
   premium or discount. Facility fees received are recognized as income over the
   expected term of the loan.

   C INCOME TAXES -- The Fund has elected to be treated as a regulated
   investment company (RIC) for United States federal tax purposes. The Fund's
   policy is to comply with the provisions of Section 817-H of the Internal
   Revenue Code regarding Variable Trusts. No provision is made by the Fund for
   federal or state taxes on any taxable income of the Fund because each
   separate account in the Fund is ultimately responsible for the payment of any
   taxes. The Fund will distribute at least annually all of the Fund's net
   investment income and net realized capital gains, if any.

   D EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as
   custodian to the Fund. Pursuant to the custodian agreement, IBT receives a
   fee reduced by credits which are determined based on the average daily cash
   balance the Fund maintains with IBT. All significant credit balances used to
   reduce the Fund's custodian fees are reported as a reduction of total
   expenses in the Statement of Operations.

                                       12
<Page>

   E USE OF ESTIMATES -- The preparation of financial statements in conformity
   with accounting principles generally accepted in the United States of America
   requires management to make estimates and assumptions that affect the
   reported amounts of assets and liabilities at the date of the financial
   statements and the reported amounts of income and expense during the
   reporting period. Actual results could differ from those estimates.

   F INDEMNIFICATIONS -- Under the Trust's organizational documents, its
   officers and Trustees may be indemnified against certain liabilities and
   expenses arising out of the performance of their duties to the Fund and
   shareholders are indemnified against personal liability for the obligations
   of the Trust. Additionally, in the normal course of business, the Fund enters
   into agreements with service providers that may contain indemnification
   clauses. The Fund's maximum exposure under these arrangements is unknown as
   this would involve future claims that may be made against the Fund that have
   not yet occurred.

   G EXPENSES -- The majority of expenses of the Trust are directly identifiable
   to an individual fund. Expenses which are not readily identifiable to a
   specific fund are allocated taking into consideration, among other things,
   the nature and type of expense and the relative size of the funds.

   H OTHER -- Investment transactions are accounted for on a trade-date basis.

2  DISTRIBUTIONS TO SHAREHOLDERS

   The net income of the Fund is determined daily and substantially all of the
   net income so determined is declared as a dividend to shareholders of record
   at the time of declaration. Distributions of net income are paid monthly.
   Distributions are paid in the form of additional shares unless an election is
   made on behalf of a separate account to receive some or all of the
   distribution in cash.

   The Fund distinguishes between distributions on a tax basis and a financial
   reporting basis. Accounting principles generally accepted in the United
   States of America require that only distributions in excess of tax basis
   earnings and profits be reported in the financial statements as a return of
   capital. Differences in the recognition or classification of income between
   the financial statements and tax earnings and profits which result in
   temporary over distributions for financial statement purposes are classified
   as distributions in excess of net investment income or accumulated net
   realized gains. Permanent differences between book and tax accounting
   relating to distributions are reclassified to paid-in capital.

3  SHARES OF BENEFICIAL INTEREST

   The Trust has an underwriting agreement relating to the Fund with Eaton Vance
   Distributors, Inc. (EVD). EVD intends to offer shares of the Fund
   continuously to separate accounts of various insurance companies. The
   underwriting agreement presently provides that EVD through the Fund's
   transfer agent accepts orders for shares at net asset value and no sales
   commission or load is charged. EVD may, at its expense, provide promotional
   incentives to dealers that sell variable insurance products. The Fund's
   Declaration of Trust permits the Trustees to issue an unlimited number of
   full and fractional shares of beneficial interest. Transactions in Fund
   shares were as follows:

4  INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

   The investment adviser fee, computed at the monthly rate of 0.575% per annum
   of the average daily net assets up to $1 billion, and at reduced rates as
   daily net assets exceed that level, was earned by Eaton Vance Management
   (EVM), as compensation for management and investment advisory services
   rendered to the Fund. For the year ended December 31, 2003, the fee amounted
   to $212,547. Except as to Trustees of the Fund who are not members of EVM's
   organization, officers and Trustees receive remuneration for their services
   to the Fund out of such investment adviser fee.

   The Fund is authorized to pay EVM a fee as compensation for administrative
   services necessary to conduct the Fund's business. The fee is computed at the
   annual rate of 0.25% of the Fund's average daily net assets. For the year
   ended December 31, 2003, the fee amounted to $92,412.

   Certain officers and Trustees of the Fund are officers of the above
   organizations.

5  SERVICE FEES

   The Fund has adopted a service plan that allows the Fund to pay service fees
   to insurance companies for providing personal and/or account services to
   account holders of insurance product separate accounts, which will be equal
   to 0.25% of daily average net assets. Service fee payments for the year ended
   December 31, 2003 amounted to $92,412.

6  PURCHASES AND SALES OF INVESTMENTS

   The Fund invests primarily in Senior Loans. The ability of the issuers of the
   Senior Loans to meet their obligations may be affected by economic
   developments in a specific industry. The cost of purchases and the proceeds
   from principal repayments of Senior Loans for the year ended December 31,
   2003 aggregated $41,757,401 and $18,586,887 respectively.

7  LINE OF CREDIT

   The Fund participates with other portfolios and funds managed by EVM and
   affiliates in a $500 million unsecured line of credit with a group of banks.
   Borrowings will be made by the Fund solely to facilitate the handling of
   unusual and/or unanticipated short-term cash requirements. Interest is
   charged to each participating portfolio or fund based on its borrowings at
   the bank's base rate or at an amount above LIBOR. In addition, a fee computed
   at an annual rate of 0.10% on the daily unused portion of the line of credit
   is allocated among the participating portfolios and funds at the end of each
   quarter. The Fund did not have any borrowings or allocated fees during the
   year ended December 31, 2003.

8  FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION)

   The cost and unrealized appreciation/depreciation in the value of the
   investments owned at December 31, 2003, as computed on a federal income tax
   basis, were as follows:

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2003
INDEPENDENT AUDITORS' REPORT

TO THE TRUSTEES OF EATON VANCE VARIABLE TRUST AND SHAREHOLDERS OF EATON VANCE VT
FLOATING-RATE INCOME FUND:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Eaton Vance VT Floating-Rate Income Fund (the
Fund), one of the series constituting Eaton Vance Variable Trust, as of December
31, 2003, and the related statements of operations for the year then ended, the
statements of changes in net assets for the two years then ended and the
financial highlights for the two years ended December 31, 2003, and for the
period from the start of business, May 2, 2001, to December 31, 2001. These
financial statements and financial highlights are the responsibility of the
Fund'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 auditing standards generally accepted
in the United States of America. 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 procedure included confirmation of
securities owned at December 31, 2003, by correspondence with the custodian,
brokers and selling or agent banks; where replies were not received from brokers
and selling or agent banks, we performed other auditing procedures. 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the Eaton Vance VT
Floating-Rate Income Fund at December 31, 2003, the results of its operations,
the changes in its net assets and the financial highlights for the respective
stated periods in conformity with accounting principles generally accepted in
the United States of America.

committee at least annually. The registrant's audit committee maintains full
