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) [PHOTO OF SCOTT H. PAGE] SCOTT H. PAGE 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. [PHOTO OF PAYSON F. SWAFFIELD] 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. FUND INFORMATION as of December 31, 2003 PERFORMANCE(1) Average Annual Total Return (at net asset value) <Table> One Year 2.93% Life of Fund (5/2/01) 1.70 </Table> 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.

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.

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: <Table> <Caption> YEAR ENDED DECEMBER 31, --------------------------------------------------------------------- 2003 2002 --------------------------------------------------------------------- Sales 1,963,869 2,823,284 Issued to shareholders electing to receive payments of distributions in Fund shares 81,191 7,242 Redemptions (1,190,229) (754,434) --------------------------------------------------------------------- NET INCREASE 854,831 2,076,092 --------------------------------------------------------------------- </Table> 13 <Page> 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: <Table> AGGREGATE COST $ 44,248,707 ------------------------------------------------------- Gross unrealized appreciation $ 260,086 Gross unrealized depreciation (6,130) ------------------------------------------------------- NET UNREALIZED APPRECIATION $ 253,956 ------------------------------------------------------- </Table> 14 <Page> 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.

(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.

(2) Eaton Vance Management, a subsidiary of Eaton Vance Corp., acts in an investment advisory and/or service provider capacity with respect to the Series. (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 advisers and any entity controlling, controlled by, or under common control with the advisers 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.
