                      PORTFOLIO HOLDINGS, AND PROXY VOTING

PRIVACY. The Eaton Vance organization is committed to ensuring your financial
privacy. Each of the financial institutions identified below has in effect the
following policy ("Privacy Policy") with respect to nonpublic personal
information about its customers:

 - Only such information received from you, through application forms or
   otherwise, and information about your Eaton Vance fund transactions will be
   collected. This may include information such as name, address, social
   security number, tax status, account balances and transactions.

 - None of such information about you (or former customers) will be disclosed to
   anyone, except as permitted by law (which includes disclosure to employees
   necessary to service your account). In the normal course of servicing a
   customer's account, Eaton Vance may share information with unaffiliated third
   parties that perform various required services such as transfer agents,
   custodians and broker/dealers.

 - Policies and procedures (including physical, electronic and procedural
   safeguards) are in place that are designed to protect the confidentiality of
   such information.

 - We reserve the right to change our Privacy Policy at any time upon proper
   notification to you. Customers may want to review our Policy periodically for
   changes by accessing the link on our homepage: www.eatonvance.com.

Our pledge of privacy applies to the following entities within the Eaton Vance
organization: the Eaton Vance Family of Funds, Eaton Vance Management, Eaton
Vance Investment Counsel, Boston Management and Research, and Eaton Vance
Distributors, Inc.

In addition, our Privacy Policy only applies to those Eaton Vance customers who
are individuals and who have a direct relationship with us. If a customer's
account (i.e., fund shares) is held in the name of a third-party financial
adviser/broker-dealer, it is likely that only such adviser's privacy policies
apply to the customer. This notice supersedes all previously issued privacy
disclosures.

      For more information about Eaton Vance's Privacy Policy, please call
                                 1-800-262-1122.

DELIVERY OF SHAREHOLDER DOCUMENTS. The Securities and Exchange Commission
permits funds to deliver only one copy of shareholder documents, including
prospectuses, proxy statements and shareholder reports, to fund investors with
multiple accounts at the same residential or post office box address. This
practice is often called "householding" and it helps eliminate duplicate
mailings to shareholders.

EATON VANCE, OR YOUR FINANCIAL ADVISER, MAY HOUSEHOLD THE MAILING OF YOUR
DOCUMENTS INDEFINITELY UNLESS YOU INSTRUCT EATON VANCE, OR YOUR FINANCIAL
ADVISER, OTHERWISE.

If you would prefer that your Eaton Vance documents not be householded, please
contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance
documents will be effective within 30 days of receipt by Eaton Vance or your
financial adviser.

PORTFOLIO HOLDINGS. Each Eaton Vance Fund and its underlying Portfolio (if
applicable) will file a schedule of its portfolio holdings on Form N-Q with the
Securities and Exchange Commission for the first and third quarters of each
fiscal year. The Form N-Q will be available on the Eaton Vance website
www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR
database on the Securities and Exchange Commision's website at www.sec.gov. Form
N-Q may also be reviewed and copied at the SEC's public reference room in
Washington, D.C. (call 1-800-732-0330 for information on the operation of the
public reference room).

PROXY VOTING. From time to time, funds are required to vote proxies related to
the securities held by the funds. The Eaton Vance Funds or their underlying
Portfolios (if applicable) vote proxies according to a set of policies and
procedures approved by the Funds' and Portfolios' Boards. You may obtain a
description of these policies and procedures and information on how the Funds or
Portfolios voted proxies relating to Portfolio securities during the 12 month
period ended June 30, without charge, upon request, by calling 1-800-262-1122.
This description is also available on the Securities and Exchange Commission's
website at www.sec.gov.

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2004

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

THE FUND

  PERFORMANCE FOR THE YEAR ENDED DECEMBER 31, 2004

- - The Fund distributed $0.253 in income dividends during the year ended December
  31, 2004. Based on a $10.10 net asset value on December 31, 2004, the Fund had
  a distribution rate of 3.04%.(1)

- - The Fund had a total return of 2.82% during the year ended December 31,
  2004.(2) That return was the result of an increase in net asset value per
  share to $10.10 on December 31, 2004 from $10.07 on December 31, 2003 and the
  reinvestment of all dividends.

- - For comparison, the S&P/LSTA Leveraged Loan Index (see next page for
  additional information about the Fund's new benchmark), had a return of 5.12%
  for the year ended December 31, 2004.(3)

  THE PORTFOLIO'S INVESTMENTS

- - The Fund's investment objective is to provide a high level of current income.
  To do so, the Fund normally invests primarily in income-producing senior,
  floating-rate loans and other floating-rate debt securities.

- - The Fund's investments included 238 borrowers at December 31, 2004, ranging
  across 35 different industries. The Fund's average loan size was just 0.24% of
  net assets, and no industry constituted more than 8% of the Portfolio.
  Publishing, health care, containers and glass, telecommunications and cable
  and satellite television were the Fund's largest industry weightings.*

- - The Federal Reserve raised its Federal Funds rate - a short-term interest rate
  benchmark - five times from June 30 through 2004 year-end. With their
  relatively short interest rate reset provisions, floating-rate loans have
  historically generated higher income in response to rising short-term rates.
  At December 31, 2004, the Fund had an average days-to-reset of 53 days.

- - Due to improving fundamentals and strong technical factors in the loan market,
  loan credit spreads for new issues narrowed and prices averaged above-par in
  the secondary market. These trends have increased the importance of diligent
  credit risk-management.

THE VIEWS EXPRESSED IN THIS REPORT ARE THOSE OF THE PORTFOLIO MANAGERS AND ARE
CURRENT ONLY THROUGH THE END OF THE PERIOD OF THE REPORT AS STATED ON THE COVER.
THESE VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED UPON MARKET OR OTHER
CONDITIONS, AND EATON VANCE DISCLAIMS ANY RESPONSIBILITY TO UPDATE SUCH VIEWS.
THESE VIEWS MAY NOT BE RELIED ON AS INVESTMENT ADVICE AND, BECAUSE INVESTMENT
DECISIONS FOR AN EATON VANCE FUND ARE BASED ON MANY FACTORS, MAY NOT BE RELIED
ON AS AN INDICATION OF TRADING INTENT ON BEHALF OF ANY EATON VANCE FUND.

     * Holdings and industry weightings are subject to change due to active
       management.

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. YIELD WILL
VARY.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. RETURNS ARE HISTORICAL AND
ARE CALCULATED BY DETERMINING THE PERCENTAGE CHANGE IN NET ASSET VALUE OR
OFFERING PRICE (AS APPLICABLE) WITH ALL DISTRIBUTIONS REINVESTED. 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
LOWER OR HIGHER THAN THE QUOTED RETURN. FOR PERFORMANCE AS OF THE MOST RECENT
MONTH-END, PLEASE REFER TO www.eatonvance.com.

(1)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.
(2) 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.
(3) IT IS NOT POSSIBLE TO INVEST DIRECTLY IN AN INDEX. THE INDEX'S TOTAL RETURN
DOES NOT REFLECT THE COMMISSIONS OR EXPENSES THAT WOULD HAVE BEEN INCURRED IF AN
INVESTOR INDIVIDUALLY PURCHASED OR SOLD THE SECURITIES REPRESENTED IN THE INDEX.

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2004

PERFORMANCE

The line graph and table set forth below provide information about the Fund's
performance. The line graph compares the performance of the Fund with that of
the S&P/LSTA Leveraged Loan Index, an unmanaged loan market index. With this
report, we are establishing the S&P/LSTA Index as the Fund's primary benchmark
in the belief that it more accurately reflects the Fund's investment universe
than does the Fund's previous benchmark, the CSFB Leveraged Loan Index. In
accordance with Securities and Exchange Commission regulations, we are including
both Indexes for this report only. The lines on the graph represent the total
returns of a hypothetical investment of $10,000 in the Fund and in the S&P/LSTA
Leveraged Loan Index and the CSFB Leveraged Loan Index. The table includes the
total returns of the Fund at net asset value. There is no sales charge.
Insurance-related sales charges are not included in calculations of returns.
Please refer to the report for your insurance contract for performance data
reflecting insurance-related charges.

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2004

FUND EXPENSES

EXAMPLE: As a shareholder of the Fund, you incur ongoing costs, including
transaction costs; management fees; distribution or service 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. The Example is based on an investment
of $1,000 invested at the beginning of the period and held for the entire period
(July 1, 2004 - December 31, 2004).

ACTUAL EXPENSES: The first section of the table below provides information about
actual account values and actual expenses. You may use the information in this
line, together with the amount you invested, to estimate the expenses that you
paid over the period. Simply divide your account value by $1,000 (for example,
an $8,600 account value divided by $1,000 = 8.6), then multiply the result by
the number in the first line under the heading entitled "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES: The second section of the table
below provides information about hypothetical account values and hypothetical
expenses based on the actual Fund expense ratio and an assumed rate of return of
5% per year (before expenses), which is not the actual return of the Fund. 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 this
information to compare the ongoing costs of investing in your Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
insurance-related charges, sales charges (loads) or redemption fees (if
applicable). Therefore, the second section of 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 transactional costs were included,
your costs would have been higher.

          multiplied by the average account value over the period, multiplied by
          184/366 (to reflect the one-half year period). The example assumes
          that the $1,000 was invested at the net asset value per share
          determined at the close of business on June 30, 2004. Returns do not
          include insurance-related charges.

Note: The Fund has made commitments to fund specified amounts under certain
existing credit arrangements. Pursuant to the terms of these arrangements, the
Fund had unfunded loan commitments of $513,737 as of December 31, 2004.

(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 three years. The
     stated interest rate represents the weighted average interest rate of all
     contracts within the senior loan facility. Interest rates are periodically
     predetermined by a reference to a base lending rate plus a premium. These
     base lending rates are generally (i) the prime rate offered by one or more
     major United States banks or (ii) the lending rate offered by one or more
     European banks such as the London Interbank Offered Rate (LIBOR).

(2)  Security valued at fair value using methods determined in good faith by or
     at the direction of the Trustees.

(3)  Security exempt from registration under Rule 144A of the Securities Act of
     1933. These securities may be sold in transactions exempt from
     registration, normally to qualified institutional buyers. At December 31,
     2004, the aggregate value of the securities is $400,883 or 0.5% of the
     Fund's net assets.

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2004
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
     under 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 60 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 than 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. At December 31,
     2004, the Fund, for federal income tax purposes had a capital loss
     carryover of $48,462, which will expire on December 31, 2012. This amount
     will reduce the Fund's taxable income arising from future net realized
     gains on investments, if any, to the extent permitted by the Internal
     Revenue Code and thus will reduce the amount of distributions to
     shareholders which would otherwise be necessary to relieve the Fund of any
     liability for federal income tax. Additionally, at December 31, 2004, the
     Fund had a net capital loss of $39,167 attributable to security
     transactions incurred after October 31, 2004. This capital loss is treated
     as arising on the first day of the Fund's taxable year ending December 31,
     2005.

     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 credit balances used to reduce the
     Fund's custodian fees are reported as a reduction of total expenses in the
     Statement of Operations.

     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 and 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.

     The tax character of distributions paid for the years ended December 31,
     2004 and December 31, 2003 was as follows:

3    SHARES OF BENEFICIAL INTEREST

     The Trust has an underwriting agreement relating to the Fund with Eaton
     Vance Distributors, Inc. (EVD). 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 (without par value). At December 31, 2004, two
     shareholders each owned more than 10% of the Fund's shares outstanding
     aggregating 90% of the Fund's shares outstanding. 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, 2004, the
     fee amounted to $365,784. 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, 2004, the fee amounted to $159,037.

     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, 2004 amounted to $159,037.

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,
     2004 aggregated $68,060,886 and $34,201,558, respectively.

7    LINE OF CREDIT

     The Fund participates with other portfolios and funds managed by EVM and
     affiliates in a $465 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, 2004.

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, 2004, as computed on a federal income tax
     basis, were as follows:

     AGGREGATE COST                         $  73,814,875
     ----------------------------------------------------
     Gross unrealized appreciation          $     568,581
     Gross unrealized depreciation                (36,542)
     ----------------------------------------------------
     NET UNREALIZED APPRECIATION            $     532,039
     ----------------------------------------------------

9    DUE TO AGENT BANK

     On December 24, 2004, the Fund was incorrectly credited $1,842,272. This
     amount was returned to the agent bank on January 5, 2005. At December 31,
     2004, the Fund had a payment due to the agent bank of $1,842,272.

EATON VANCE VT FLOATING-RATE INCOME FUND as of December 31, 2004
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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, 2004, and the related statement 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 three years ended December 31, 2004 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 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 are free of material misstatement. An audit includes consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities and Senior Loans owned at December 31, 2004 by correspondence with
the custodian and selling or agent banks; where replies were not received from
selling or agent banks, we performed other auditing procedures. 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, 2004, 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.

PRIVACY. The Eaton Vance organization is committed to ensuring your financial
privacy. Each of the financial institutions identified below has in effect the
following policy ("Privacy Policy") with respect to nonpublic personal
information about its customers:

 - Only such information received from you, through application forms or
   otherwise, and information about your Eaton Vance fund transactions will be
   collected. This may include information such as name, address, social
   security number, tax status, account balances and transactions.

 - None of such information about you (or former customers) will be disclosed to
   anyone, except as permitted by law (which includes disclosure to employees
   necessary to service your account). In the normal course of servicing a
   customer's account, Eaton Vance may share information with unaffiliated third
   parties that perform various required services such as transfer agents,
   custodians and broker/dealers.

 - Policies and procedures (including physical, electronic and procedural
   safeguards) are in place that are designed to protect the confidentiality of
   such information.

 - We reserve the right to change our Privacy Policy at any time upon proper
   notification to you. Customers may want to review our Policy periodically for
   changes by accessing the link on our homepage: www.eatonvance.com.

Our pledge of privacy applies to the following entities within the Eaton Vance
organization: the Eaton Vance Family of Funds, Eaton Vance Management, Eaton
Vance Investment Counsel, Boston Management and Research, and Eaton Vance
Distributors, Inc.

In addition, our Privacy Policy only applies to those Eaton Vance customers who
are individuals and who have a direct relationship with us. If a customer's
account (i.e., fund shares) is held in the name of a third-party financial
adviser/broker-dealer, it is likely that only such adviser's privacy policies
apply to the customer. This notice supersedes all previously issued privacy
disclosures.

                                1-800-262-1122.

DELIVERY OF SHAREHOLDER DOCUMENTS. The Securities and Exchange Commission
permits funds to deliver only one copy of shareholder documents, including
prospectuses, proxy statements and shareholder reports, to fund investors with
multiple accounts at the same residential or post office box address. This
practice is often called "householding" and it helps eliminate duplicate
mailings to shareholders.

EATON VANCE, OR YOUR FINANCIAL ADVISER, MAY HOUSEHOLD THE MAILING OF YOUR
DOCUMENTS INDEFINITELY UNLESS YOU INSTRUCT EATON VANCE, OR YOUR FINANCIAL
ADVISER, OTHERWISE.

If you would prefer that your Eaton Vance documents not be householded, please
contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance
documents will be effective within 30 days of receipt by Eaton Vance or your
financial adviser.

PORTFOLIO HOLDINGS. Each Eaton Vance Fund and its underlying Portfolio (if
applicable) will file a schedule of its portfolio holdings on Form N-Q with the
Securities and Exchange Commission for the first and third quarters of each
fiscal year. The Form N-Q will be available on the Eaton Vance website
www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR
database on the Securities and Exchange Commision's website at www.sec.gov. Form
N-Q may also be reviewed and copied at the SEC's public reference room in
Washington, D.C. (call 1-800-732-0330 for information on the operation of the
public reference room).

PROXY VOTING. From time to time, funds are required to vote proxies related to
the securities held by the funds. The Eaton Vance Funds or their underlying
Portfolios (if applicable) vote proxies according to a set of policies and
procedures approved by the Funds' and Portfolios' Boards. You may obtain a
description of these policies and procedures and information on how the Funds or
Portfolios voted proxies relating to Portfolio securities during the 12 month
period ended June 30, without charge, upon request, by calling 1-800-262-1122.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

[PHOTO OF SAMUEL D. ISALY]

Samuel D. Isaly
Portfolio Manger

THE FUND

Performance for the Past Year

- - During the 12 months ended December 31, 2004, the Fund's shares had a total
  return of 6.24%.(1) This return was the result of an increase in net asset
  value to $11.24 on December 31, 2004, from $10.58 on December 31, 2003.

- - The Fund underperformed its peer group, the Lipper Health/Biotechnology Fund
  Classification, which had an average return of 9.12% for the 12 months ended
  December 31, 2004.(2) Because the health care sector's performance lagged that
  of the broader market, the Fund's performance also lagged its benchmark
  indices, the S&P 500 Index, which returned 10.87%, and the Morgan Stanley
  Capital International Europe, Australasia and Far East Index, which returned
  20.25%.

MANAGEMENT DISCUSSION

- - The health care sector had positive returns during 2004, but performance
  slowed considerably from the prior year. Although industry fundamentals
  remained generally healthy, investors shied away from big pharmaceutical
  companies, which struggled, and smaller biotech companies, which were more
  volatile.

- - Large, established biotechnology companies led the sector's returns, with
  solid financial results and generally positive news on product development and
  sales. In the first half of the year, both the flow of product news and the
  rate of new product approvals were strong. The FDA approved 16 New Molecular
  Entities (innovative new products) in the first six months of the year,
  compared with 21 for all of 2003.

- - In the second half, big pharmaceuticals were hurt by news that a large
  pharmaceutical company had recalled its arthritis drug on concerns about heart
  attack and stroke risks. In addition, the market's valuation for health care
  stocks was compressed, relative to earnings. While earnings per share grew at
  a rate of approximately 20% for many large biotech and pharmaceutical
  companies, price per share increases were 10% or less.

- - The Fund's policy of investing in a worldwide and diversified portfolio of
  health care stocks for long-term capital growth caused it to underperform its
  broad benchmark indexes, which reflect U.S. and international stocks in all
  industry sectors -- many of which outperformed the health care sector. The
  Fund's performance during the period was helped by its investments in large
  global biotechnology companies, which led the sector's annual returns,
  including one that focuses on hematology, oncology, and inflammation
  treatments, and another that focuses on treating genetic disorders, renal
  disease, osteoarthritis, and organ transplants.

- - Other large pharmaceuticals detracted from the Fund's returns, including one
  high-profile company known for its previous success with an erectile
  dysfunction drug, and another that declined on fears that its recall of diet
  drugs years earlier could result in potential litigation.

- - In the emerging biotechnology group, a company that makes drugs for cancer,
  pain, and hormone-related health issues, detracted from performance, as did a
  firm that is developing small molecule drugs and has a number of products in
  the clinical and preclinical development stages. These products are intended
  to treat bone and mineral disorders, gastrointestinal disorders, and problems
  with the central nervous system.

- - We believe that the relatively lackluster growth in stock price appreciation
  relative to earnings growth can create opportunity for the future, as we feel
  stock prices should eventually reflect the strong underlying fundamentals that
  many companies in the health care sector possess.

THE VIEWS EXPRESSED THROUGHOUT THIS REPORT ARE THOSE OF THE PORTFOLIO MANAGER
AND ARE CURRENT ONLY THROUGH THE END OF THE PERIOD OF THE REPORT AS STATED ON
THE COVER. THESE VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED UPON MARKET OR
OTHER CONDITIONS, AND THE INVESTMENT ADVISER DISCLAIMS ANY RESPONSIBILITY TO
UPDATE SUCH VIEWS. THESE VIEWS MAY NOT BE RELIED ON AS INVESTMENT ADVICE AND,
BECAUSE INVESTMENT DECISIONS FOR A FUND ARE BASED ON MANY FACTORS, MAY NOT BE
RELIED ON AS AN INDICATION OF TRADING INTENT ON BEHALF OF ANY EATON VANCE FUND.

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. RETURNS ARE HISTORICAL AND
ARE CALCULATED BY DETERMINING THE PERCENTAGE CHANGE IN NET ASSET VALUE WITH ALL
DISTRIBUTIONS REINVESTED. 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 LOWER OR HIGHER THAN QUOTED. FOR
PERFORMANCE AS OF THE MOST RECENT MONTH-END, PLEASE REFER TO www.eatonvance.com.

(1) These returns do not include insurance-related charges. Please refer to the
    report for your insurance contract for performance data reflecting
    insurance-related charges. There is no sales charge.

(2) It is not possible to invest directly in an Index or a Lipper
    Classification. The Index's total return does not reflect commissions or
    expenses that would have been incurred if an investor individually purchased
    or sold the securities represented in the Index.

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.

EATON VANCE VT WORLDWIDE HEALTH SCIENCES FUND as of December 31, 2004

FUND EXPENSES

EXAMPLE: As a shareholder of the Fund, you incur ongoing costs, including
transaction costs; management fees; distribution or service 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. The Example is based on an investment
of $1,000 invested at the beginning of the period and held for the entire period
(July 1, 2004 - December 31, 2004).

ACTUAL EXPENSES: The first section of the table below provides information about
actual account values and actual expenses. You may use the information in this
line, together with the amount you invested, to estimate the expenses that you
paid over the period. Simply divide your account value by $1,000 (for example,
an $8,600 account value divided by $1,000 = 8.6), then multiply the result by
the number in the first line under the heading entitled "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES: The second section of the table
below provides information about hypothetical account values and hypothetical
expenses based on the actual Fund expense ratio and an assumed rate of return of
5% per year (before expenses), which is not the actual return of the Fund. 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 this
information to compare the ongoing costs of investing in your Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
insurance-related charges, sales charges (loads) or redemption fees (if
applicable). Therefore, the second section of 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 transactional costs were included,
your costs would have been higher.

</Table>

      * Expenses are equal to the Fund's annualized expense ratio of 1.83%
        multiplied by the average account value over the period, multiplied by
        184/366 (to reflect the one-half year period). The example assumes that
        the $1,000 was invested at the net asset value per share determined at
        the close of business on June 30, 2004. Returns do not include
        insurance-related charges.

EATON VANCE VT WORLDWIDE HEALTH SCIENCES FUND as of December 31, 2004
NOTES TO FINANCIAL STATEMENTS

1    SIGNIFICANT ACCOUNTING POLICIES

Eaton Vance VT Worldwide Health Sciences Fund (the Fund) is a diversified series
of Eaton Vance Variable Trust (the Trust). The Trust is an entity of the type
commonly known as a Massachusetts business trust and is registered under the
Investment Company Act of 1940, as amended, as an open-end management investment
company. The Fund seeks long-term capital growth by investing in a global and
diversified portfolio of securities of health sciences companies. The Fund is
made available only to separate accounts issued by participating insurance
companies. 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 -- Securities listed on a U.S. securities exchange
generally are valued at the last sale price on the day of valuation or, if no
sales took place on such date, at the mean between the closing bid and asked
prices therefore on the exchange where such securities are principally traded.
Equity securities listed on the NASDAQ National Market System generally are
valued at the official NASDAQ closing price. Unlisted or listed securities for
which closing sales prices or closing quotations are not available are valued at
the mean between the latest available bid and asked prices or, in the case of
preferred equity securities that are not listed or traded in the
over-the-counter market, by an independent pricing service. The value of
preferred equity securities that are valued by a pricing service on a bond basis
will be adjusted by an income factor, to be determined by the investment
adviser, to reflect the next anticipated regular dividend. Exchange-traded
options are valued at the last sale price for the day of valuation as quoted on
the principal exchange or board of trade on which the options are traded or, in
the absence of sales on such date, at the mean between the latest bid and asked
prices therefore. Futures positions on securities and currencies generally are
valued at closing settlement prices. Short-term debt securities with a remaining
maturity of 60 days or less are valued at amortized cost. If short-term debt
securities were acquired with a remaining maturity of more than 60 days, their
amortized cost value will be based on their value on the sixty-first day prior
to maturity. Other fixed income and debt securities, including listed securities
and securities for which price quotations are available, will normally be valued
on the basis of valuations furnished by a pricing service. The daily valuation
of foreign securities generally is determined as of the close of trading on the
principal exchange on which such securities trade. Events occurring after the
close of trading on foreign exchanges may result in adjustments to the valuation
of foreign securities to more accurately reflect their fair value as of the
close of regular trading on the New York Stock Exchange. The Fund may rely on an
independent fair valuation service in adjusting the valuations of foreign
securities. Foreign securities and currencies are valued in U.S. dollars, based
on foreign currency exchange rate quotations supplied by an independent
quotation service. Investments held by the Fund for which valuations or market
quotations are unavailable are valued at fair value using methods determined in
good faith by or at the direction of the Trustees of the Fund considering
relevant factors, data and information including the market value of freely
tradable securities of the same class in the principal market on which such
securities are normally traded.

B INCOME -- Interest income is determined on the basis of interest accrued,
adjusted for amortization of premium or accretion of discount. Dividend income
is recorded on the ex-dividend date for dividends received in cash and/or
securities. However, if the ex-dividend date has passed, certain dividends from
foreign securities are recorded as the Fund is informed of the ex-dividend date.
Withholding taxes on foreign dividends and capital gains have been provided for
in accordance with the Fund's understanding of the applicable countries' tax
rules and rates.

C FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute to shareholders each year all of its taxable income, including any
net realized capital gains. Accordingly, no provision for federal income or
excise tax is necessary. At December 31, 2004, the Fund, for federal income tax
purposes had a capital loss carryover of $66,856, which will expire on December
31, 2011. This amount will reduce the Fund's taxable income arising from future
net realized gains on investments, if any, to the extent permitted by the
Internal Revenue Code and thus will reduce the amount of distributions to
shareholders which would otherwise be necessary to relieve the Fund of any
liability for federal income tax. During the year ended December 31, 2004,
capital loss carryovers of $731,943 were utilized to offset net realized gains.

D EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as custodian
of 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 credit balances used to reduce the Fund's custodian fees
are reported as a reduction of total expenses in the Statement of Operations.

                                       10
<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 revenue 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 FOREIGN CURRENCY TRANSLATION -- Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. Purchases and
sales of foreign investment securities and income and expenses are converted
into U.S. dollars based upon currency exchange rates prevailing on the
respective dates of such transactions. Realized gains or losses on investment
transactions attributable to changes in foreign currency exchange rates are
recorded for financial statement purposes as net realized gains and losses on
investments. That portion of unrealized gains and losses on investments that
results from fluctuations in foreign currency exchange rates is not separately
disclosed.

I FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The Fund may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering these contracts from the potential inability of counterparties to meet
the terms of their contracts and from movements in the value of a foreign
currency relative to the U.S. dollar. The Fund will enter into forward contracts
for hedging purposes as well as nonhedging purposes. The forward foreign
currency exchange contracts are adjusted by the daily exchange rate of the
underlying currency and any gains and losses are recorded for financial
statement purposes as unrealized until such time as the contracts have been
closed.

J OTHER -- Investment transactions are accounted for on a trade date basis.
Realized gains and losses are computed based on the specific identification of
the securities sold.

2    DISTRIBUTIONS TO SHAREHOLDERS

It is the present policy of the Fund to make at least one distribution annually
(normally in December) of all or substantially all of its net investment income
and at least one distribution annually of all of its net realized capital gains.
Distributions are paid in the form of additional shares of the Fund unless an
election is made on behalf of a separate account to receive some or all of the
distribution in cash. Shareholders may reinvest all distributions in shares of
the Fund at the net asset value as of the close of business on the ex-dividend
date.

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.
Permanent differences between book and tax accounting relating to distributions
are reclassified to paid-in capital.

During the year ended December 31, 2004, paid-in capital was decreased by
$323,669, accumulated net investment loss was decreased by $316,802, and
accumulated net realized loss was decreased by $6,867 primarily due to
differences between book and tax policies for net operating losses and foreign
currency gain/loss. This change had no effect on the net assets or the net asset
value per share.

As of December 31, 2004, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:

<Table>
                                        
Capital loss carryforwards                 $    (66,856)
Net unrealized appreciation                $  2,528,199
</Table>

The temporary differences between book and tax basis distributable earnings
(accumulated losses) are due to wash sales.

3    SHARES OF BENEFICIAL INTEREST

The Trust has an underwriting agreement relating to the Fund with Eaton Vance
Distributors, Inc. (EVD). 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 (without par value).
At December 31, 2004, separate accounts of two insurance companies owned 60% and
40%, respectively, of the Fund's shares outstanding. Transactions in Fund shares
were as follows:

4    INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Pursuant to the Advisory Agreement, OrbiMed Advisors, LLC (OrbiMed) serves as
the Investment Adviser of the Fund. Under this agreement, OrbiMed receives a
monthly fee at the annual rate of 1% of the Fund's first $30 million in average
net assets, 0.90% of the next $20 million in average net assets, 0.75% of the
next $450 million in average net assets, and 0.70% of the next $500 million in
average net assets. The fee rate declines for net assets of $1 billion and
greater. In addition, effective May 1, 2002, OrbiMed's fee is subject to an
upward or downward performance fee adjustment of up to 0.25% of the average
daily net assets of the Fund based upon the investment performance of the Fund
compared to the Standard & Poor's Index of 500 Common Stocks over specified
periods. For the year ended December 31, 2004, the fee was equivalent to 1.05%
of the Fund's average daily net assets and amounted to $281,541.

Under an Administration Agreement between the Fund and its Administrator, Eaton
Vance Management (EVM), EVM manages and administers the affairs of the Fund. EVM
earns a monthly fee at the annual rate of 0.25% of average daily net assets. For
the year ended December 31, 2004, the administration fee was 0.25% of average
net assets and amounted to $67,120.

Except for Trustees of the Fund who are not members of the Adviser or EVM's
organization, officers and Trustees receive remuneration for their services to
the Fund out of such investment adviser and administration fees. 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 is equal to 0.25% of daily
average net assets. Service fees for the year ended December 31, 2004 amounted
to $67,120.

6    RISKS ASSOCIATED WITH FOREIGN INVESTMENTS

Investing in securities issued by companies whose principal business activities
are outside the United States may involve significant risks not present in
domestic investments. For example, there is generally less publicly available
information about foreign companies, particularly those not subject to the
disclosure and reporting requirements of the U.S. securities laws. Foreign
issuers are generally not bound by uniform accounting, auditing, and financial
reporting requirements and standards of practice comparable to those applicable
to domestic issuers. Investments in foreign securities also involve the risk of
possible adverse changes in investment or exchange control regulations,
expropriation or confiscatory taxation, limitation on the removal of funds or
other assets of the Fund, political or financial instability or diplomatic and
other developments which could affect such investments. Foreign stock markets,
while growing in volume and sophistication, are generally not as developed as
those in the United States, and securities of some foreign issuers (particularly
those in developing countries) may be less liquid and more volatile than
securities of comparable U.S. companies. In general, there is less overall
governmental supervision and regulation of foreign securities markets,
broker-dealers, and issuers than in the United States.

7    PURCHASES AND SALES OF INVESTMENTS

Purchases and sales of investments, other than short-term obligations,
aggregated $8,416,078 and $5,145,545, respectively, for the year ended December
31, 2004.

8    LINE OF CREDIT

The Fund participates with other portfolios and funds managed by EVM and its
affiliates in a $150 million unsecured line of credit agreement with a group of
banks.

                                       12
<Page>

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 an amount
above the Eurodollar rate or federal funds rate. 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 significant borrowings or allocated fees
during the year ended December 31, 2004.

9    FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION)

The cost and unrealized appreciation (depreciation) in value of the investment
securities of the Fund at December 31, 2004, as computed on a federal income tax
basis, were as follows:

<Table>
                                        
AGGREGATE COST                             $ 25,627,028
- -------------------------------------------------------
Gross unrealized appreciation              $  5,069,260
Gross unrealized depreciation                (2,541,753)
- -------------------------------------------------------
NET UNREALIZED APPRECIATION                $  2,527,507
- -------------------------------------------------------
</Table>

The net unrealized appreciation on foreign currency was $692 at December 31,
2004.

EATON VANCE VT WORLDWIDE HEALTH SCIENCES FUND as of December 31, 2004
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Shareholders
of Eaton Vance VT Worldwide Health Sciences Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Eaton Vance VT Worldwide Health
Sciences Fund, a series of Eaton Vance Variable Trust, (the "Fund") at December
31, 2004, and the results of its operations, the changes in its net assets and
the financial highlights for each of the periods indicated, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements 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 are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2004 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

(1)  Audit-related fees consist of the aggregate fees billed for assurance and
related services that are reasonably related to the performance of the audit of
the registrant's financial statements and are not reported under the category of
audit fees.

(2)  Tax fees consist of the aggregate fees billed for professional services
rendered by the principal accountant relating to tax compliance, tax advice, and
tax planning and specifically include fees for tax return preparation.

(3)  All other fees consist of the aggregate fees billed for products and
services provided by the registrant's principal accountant other than audit,
audit-related, and tax services.

(e)(1) The registrant's audit committee has adopted policies and procedures
relating to the pre-approval of services provided by the registrant's principal
accountant (the "Pre-Approval Policies"). The Pre-Approval Policies establish a
framework intended to assist the audit committee in the proper discharge of its
pre-approval responsibilities. As a general matter, the Pre-Approval Policies
(i) specify certain types of audit, audit-related, tax, and other services
determined to be pre-approved by the audit committee; and (ii) delineate
specific procedures governing the mechanics of the pre-approval process,
including the approval and monitoring of audit and non-audit service fees.
Unless a service is specifically pre-approved under the Pre-Approval Policies,
it must be separately pre-approved by the audit committee.

The Pre-Approval Policies and the types of audit and non-audit services
pre-approved therein must be reviewed and ratified by the registrant's audit
committee at least annually. The registrant's audit committee maintains full
responsibility for the appointment, compensation, and oversight of the work of
the registrant's principal accountant.

(e)(2) No services described in paragraphs (b)-(d) above were approved by the
registrant's audit committee pursuant to the "de minimis exception" set forth in
Rule 2-01 (c)(7)(i)(C) of Regulation S-X.

(f) Not applicable.

(g) The following table presents (i) the aggregate non-audit fees (i.e., fees
for audit-related, tax, and other services) billed to the registrant by the
registrant's principal accountant for the last two fiscal years of the
registrant; and (ii) the aggregate non-audit fees (i.e., fees for audit-related,
tax, and other services) billed to the Eaton Vance organization by the
registrant's principal accountant for the last two fiscal years of the
registrant.

(1)  The investment adviser to the registrant, as well as any of its affiliates
     that provide ongoing services to the registrant, are subsidiaries of Eaton
     Vance Corp.

(h) The registrant's audit committee has considered whether the provision by the
registrant's principal accountant of non-audit services to the registrant's
investment adviser and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the registrant that
were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is
compatible with maintaining the principal accountant's independence.
