Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees, distribution (12b-1) fees, and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.90% $1,000.00 $976.00 $4.41 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.90% $1,000.00 $1,020.33 $4.51 - ------------------------------------------------------------------------------- Actual 1.15% $1,000.00 $975.10 $5.63 Service ----------------------------------------------------------------------- Class Hypothetical* 1.15% $1,000.00 $1,019.09 $5.76 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Capital Opportunities Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 51 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $8,866 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $4,522 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for wash sales. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from ordinary income $578,041 $267,482 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $1,204,218 Capital loss carryforward (77,094,025) Unrealized appreciation (depreciation) 19,182,826 For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration. EXPIRATION DATE December 31, 2009 $(27,342,680) December 31, 2010 (49,751,345) ------------------------------------------------------------- Total $(77,094,025) MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.15% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $28,829, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $303. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0142% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $383, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $40,068, which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $57,139,374 and $66,171,625, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $167,635,129 ------------------------------------------------------ Gross unrealized appreciation $14,538,190 Gross unrealized depreciation (5,194,365) ------------------------------------------------------ Net unrealized appreciation (depreciation) $9,343,825 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 412,961 $5,401,213 1,289,648 $15,880,838 Shares issued to shareholders in reinvestment of distributions 88,515 1,107,323 45,470 551,552 Shares reacquired (1,241,446) (16,265,153) (2,106,006) (26,166,316) - ------------------------------------------------------------------------------------------------------------------------------ Net change (739,970) $(9,756,617) (770,888) $(9,733,926) SERVICE CLASS SHARES Shares sold 128,961 $1,676,555 712,230 $8,667,238 Shares issued to shareholders in reinvestment of distributions 7,862 97,889 2,193 26,488 Shares reacquired (169,396) (2,207,656) (365,881) (4,449,807) - ------------------------------------------------------------------------------------------------------------------------------ Net change (32,573) $(433,212) 348,542 $4,243,919 (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $531, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees, distribution (12b-1) fees, and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.93% $1,000.00 $1,007.70 $4.63 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.93% $1,000.00 $1,020.18 $4.66 - ------------------------------------------------------------------------------- Actual 1.18% $1,000.00 $1,007.20 $5.87 Service ----------------------------------------------------------------------- Class Hypothetical* 1.18% $1,000.00 $1,018.94 $5.91 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

The proceeds resulted in an increase in the net asset value of $0.02 per share based on shares outstanding on the day the proceeds were received. Excluding the effect of this payment from the ending net asset value per share, the Initial Class and Service Class shares total returns for the year ended December 31, 2003 would have each been lower by approximately 0.22%. + The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The non-recurring accrual resulted in an increase in the net asset value of $0.01 per share based on shares outstanding on the day the proceeds were recorded. SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Research Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 100 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street") and J.P. Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street and Chase provide the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agents. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agents. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. The series was a participant in a class-action lawsuit against Rite Aid Corporation. On February 18, 2004 the series received a cash settlement in the amount of $205,940. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $6,796 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $3,658 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions and wash sales. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from: Ordinary income $3,788,235 $3,343,481 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $1,559,568 Capital loss carryforward (330,352,148) Unrealized appreciation (depreciation) 36,961,448 For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2009, $(167,500,935) and December 31, 2010, $ (162,851,213). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $56,446, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $230. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0142% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $749, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $232,837, which resulted in an increase in net asset value of $0.01 per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $135,122,893 and $176,532,637, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $303,471,099 ------------------------------------------------------- Gross unrealized appreciation $28,729,493 Gross unrealized depreciation (10,463,044) ------------------------------------------------------- Net unrealized appreciation (depreciation) $18,266,449 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $1,124, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees, distribution (12b-1) fees, and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.90% $1,000.00 $ 998.80 $4.45 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.90% $1,000.00 $1,020.33 $4.51 - ------------------------------------------------------------------------------- Actual 1.15% $1,000.00 $ 993.80 $5.69 Service ----------------------------------------------------------------------- Class Hypothetical* 1.15% $1,000.00 $1,019.09 $5.76 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Investors Trust Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 86 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The series 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 into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The series may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the series may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The series may also use contracts in a manner intended to protect foreign currency- denominated securities from declines in value due to unfavorable exchange rate movements. For non-hedging purposes, the series may enter into contracts with the intent of changing the relative exposure of the series' portfolio of securities to different currencies to take advantage of anticipated changes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until the contract settlement date. On contract settlement date, the gains or losses are recorded as realized gains or losses on foreign currency transactions. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $13,511 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $12,513 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions and wash sales. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from ordinary income $3,540,484 $2,938,420 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $3,875,591 Capital loss carryforward (116,115,973) Unrealized appreciation (depreciation) 87,558,862 For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration as follows: EXPIRATION DATE December 31, 2009 $(46,073,676) December 31, 2010 (65,516,458) December 31, 2011 (4,525,839) ------------------------------------------------------ Total $(116,115,973) MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $124,011, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $327. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0142% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons, and pays no compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFD, and MFSC. OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $1,641, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $130,053, which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $250,898,375 and $229,298,491, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $691,996,004 ------------------------------------------------------------- Gross unrealized appreciation $64,190,437 Gross unrealized depreciation (16,025,971) ------------------------------------------------------------- Net unrealized appreciation (depreciation) $48,164,466 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

(6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $930, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J.

The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees, distribution (12b-1) fees, and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 1.06% $1,000.00 $ 957.60 $5.15 Initial ----------------------------------------------------------------------- Class Hypothetical* 1.06% $1,000.00 $1,019.54 $5.31 - ------------------------------------------------------------------------------- Actual 1.31% $1,000.00 $ 956.50 $6.35 Service ----------------------------------------------------------------------- Class Hypothetical* 1.31% $1,000.00 $1,018.30 $6.56 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS New Discovery Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 117 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $16,572 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $28,207 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, real estate investment trusts, net operating losses and wash sales. The series paid no distributions for the years ended December 31, 2004 and December 31, 2003. As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(49,418,250) Unrealized appreciation (depreciation) 95,050,512 Other temporary differences (1,132) For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2010. MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with MFS to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.90% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $118,601, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $717. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.01413% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $1,578, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $29,985, which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $432,750,615 and $512,631,473, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost$768,671,745 ---------------------------------------------------- Gross unrealized appreciation $58,606,474 Gross unrealized depreciation (38,191,571) ---------------------------------------------------- Net unrealized appreciation (depreciation) $20,414,903 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $3,022, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.94% $1,000.00 $959.00 $4.57 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.94% $1,000.00 $1,020.13 $4.71 - ------------------------------------------------------------------------------- Actual 1.19% $1,000.00 $957.10 $5.77 Service ----------------------------------------------------------------------- Class Hypothetical* 1.19% $1,000.00 $1,018.89 $5.96 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Mid Cap Growth Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 29 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street") and J.P. Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street and Chase provide the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agents. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agents. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $5,283 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $2,749 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, net operating losses and wash sales. The series paid no distributions for the years ended December 31, 2004 and December 31, 2003. As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(7,568,621) Unrealized appreciation (depreciation) 37,661,014 Other temporary differences (47,857) For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2010. MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $43,361, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $241. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.01416% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to the Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $575, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $243, which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $101,905,603 and $112,459,221, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $266,493,386 ---------------------------------------------------- Gross unrealized appreciation $31,388,343 Gross unrealized depreciation (10,083,512) ---------------------------------------------------- Net unrealized appreciation (depreciation) $21,304,831 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 1,044,970 $6,967,828 7,146,386 $46,647,568 Shares reacquired (2,012,094) (13,333,865) (2,633,822) (16,714,973) - ------------------------------------------------------------------------------------------------------------------------- Net change (967,124) $(6,366,037) 4,512,564 $29,932,595 SERVICE CLASS SHARES Shares sold 356,809 $2,355,568 3,284,902 $21,295,639 Shares reacquired (1,363,954) (8,960,059) (3,773,711) (23,960,565) - ------------------------------------------------------------------------------------------------------------------------- Net change (1,007,145) $(6,604,491) (488,809) $(2,664,926) (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $863, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line in 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 line in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.60% $1,000.00 $1,010.80 $2.99 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.60% $1,000.00 $1,021.82 $3.01 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Money Market Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 6 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. INVESTMENT VALUATIONS - Money market instruments are valued at amortized cost, which the Trustees have determined in good faith approximates market value. The series' use of amortized cost is subject to the series' compliance with certain conditions as specified under Rule 2a-7 of the Investment Company Act of 1940. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized and accreted for financial statement purposes and tax reporting purposes in accordance with generally accepted accounting principles and federal tax regulations, respectively. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. This amount, for the six months ended June 30, 2005, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from ordinary income $29,083 $75,392 (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.50% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.10% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $450, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $7. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0141% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $6, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. (4) PORTFOLIO SECURITIES Purchases and sales of money market investments, exclusive of securities subject to repurchase agreements, aggregated $17,957,188 and $18,299,323 respectively. (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $7, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees, distribution (12b-1) fees, and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 1.15% $1,000.00 $974.60 $5.63 Initial ----------------------------------------------------------------------- Class Hypothetical* 1.15% $1,000.00 $1,019.09 $5.76 - ------------------------------------------------------------------------------- Actual 1.40% $1,000.00 $963.20 $6.81 Service ----------------------------------------------------------------------- Class Hypothetical* 1.40% $1,000.00 $1,017.85 $7.00 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Global Equity Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 13 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. At June 30, 2005, the value of securities loaned was $5,311,822. These loans were collateralized by cash of $5,567,106 and non-cash U.S. Treasury obligations of $15,402. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex- dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $492 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $153 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions and wash sales. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from ordinary income $71,238 $5,842 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $117,885 Undistributed long-term capital gain 598,621 Unrealized appreciation (depreciation) 5,649,608 Other temporary differences (1,754) MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 1.00% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.15% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFS Fund Distributions, Inc. (MFD), a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 of the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $5,828, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $98. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.01429% of the series' average daily net assets. TRUSTEES COMPENSATION - The series pays compensation to its Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons, and pays no compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFD, and MFSC. OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $77, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $10,659,065 and $6,361,105, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $36,007,395 ---------------------------------------------------- Gross unrealized appreciation $4,182,840 Gross unrealized depreciation (611,317) ---------------------------------------------------- Net unrealized appreciation $3,571,523 ---------------------------------------------------- (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 462,144 $5,821,343 1,043,575 $11,951,565 Shares issued to shareholders in reinvestment of distributions 59,625 718,481 6,372 71,238 Shares reacquired (334,626) (4,153,951) (228,069) (2,630,927) - ---------------------------------------------------------------------------------------------------------------------------- Net change 187,143 $2,385,873 821,878 $9,391,876 SERVICE CLASS SHARES* Shares sold 25,855 $322,022 -- $-- Shares issued to shareholders in reinvestment of distributions 1** 5 -- -- Shares reacquired (21,811) (275,259) -- -- - ---------------------------------------------------------------------------------------------------------------------------- Net change 4,045 $46,768 -- $-- * For the year ended December 31, 2004, the series had no Service Class share activity. ** Shares are rounded for presentation purposes. (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $123, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.90% $1,000.00 $1,012.90 $4.49 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.90% $1,000.00 $1,020.33 $4.51 - ------------------------------------------------------------------------------- Actual 1.15% $1,000.00 $1,011.60 $5.74 Service ----------------------------------------------------------------------- Class Hypothetical* 1.15% $1,000.00 $1,019.09 $5.76 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Value Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 32 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $2,066 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $752 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions and wash sales. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from: Ordinary income $1,451,246 $34,772 Long-term capital gain 63,028 -- - -------------------------------------------------------------------------------- Total distributions declared $1,514,274 $34,772 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $2,474,519 Undistributed long-term capital gain 2,161,978 Unrealized appreciation (depreciation) 15,317,905 MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.15% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $24,284, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $418. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0143% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $320, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $56,474,095 and $11,245,228, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $153,499,242 -------------------------------------------------------- Gross unrealized appreciation $16,971,422 Gross unrealized depreciation (3,317,714) -------------------------------------------------------- Net unrealized appreciation (depreciation) $13,653,708 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $545, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.86% $1,000.00 $984.00 $4.23 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.86% $1,000.00 $1,020.53 $4.31 - ------------------------------------------------------------------------------- Actual 1.11% $1,000.00 982.70 $5.46 Service ----------------------------------------------------------------------- Class Hypothetical* 1.11% $1,000.00 $1,019.29 $5.56 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

The non-recurring accrual resulted in an increase in the net asset value of $0.01 per share based on the shares outstanding on the day the proceeds were recorded. (+) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total return figures for all periods shown. ^ The series' net asset value and total return calculation include proceeds received on March 26, 2003 for the partial payment of a non-recurring litigation settlement from Cendant Corporation, recorded as a realized gain on investment transactions. The proceeds resulted in an increase in the net asset value of $0.09 per share based on shares outstanding on the day the proceeds were received. Excluding the effect of this payment from the ending net asset value per share, the Initial Class and Service Class shares total returns for the year ended December 31, 2003 would have each been lower by approximately 0.75%. SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Emerging Growth Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 123 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street") and J.P. Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street and Chase provide the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agents. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agents. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $16,249 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $24,406 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, wash sales, and net operating losses. The series paid no distributions for the years ended December 31, 2004 and December 31, 2003. As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(784,691,808) Unrealized appreciation (depreciation) 105,547,893 For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2009, $(380,813,821) and December 31, 2010, $(403,877,987). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $137,356, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $468. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.01416% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $1,824, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $745,251, which resulted in an increase in net asset value of $0.01 per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $310,608,747 and $394,376,793, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $824,914,566 ------------------------------------------------------- Gross unrealized appreciation $76,638,276 Gross unrealized depreciation (25,265,286) ------------------------------------------------------- Net unrealized appreciation (depreciation) $51,372,990 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 1,053,402 $17,712,776 3,048,337 $48,571,686 Shares reacquired (5,286,135) (88,803,752) (10,450,550) (165,907,451) - ------------------------------------------------------------------------------------------------------------------------- Net change (4,232,733) $(71,090,976) (7,402,213) $(117,335,765) SERVICE CLASS SHARES Shares sold 318,790 $5,326,602 978,784 $15,463,022 Shares reacquired (338,637) (5,616,340) (996,320) (15,718,173) - ------------------------------------------------------------------------------------------------------------------------- Net change (19,847) $(289,738) (17,536) $(255,151) (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $2,750, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - -------------------------------------------------------------------------------- Actual 0.87% $1,000.00 $1,006.80 $4.33 Initial ------------------------------------------------------------------------ Class Hypothetical* 0.87% $1,000.00 $1,020.48 $4.36 - -------------------------------------------------------------------------------- Actual 1.12% $1,000.00 $1,006.00 $5.57 Service ------------------------------------------------------------------------ Class Hypothetical* 1.12% $1,000.00 $1,019.24 $5.61 - -------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Total Return Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 105 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Bonds and other fixed income securities (other than short-term obligations) in the series' portfolio are valued at an evaluated bid price as reported by an independent pricing service, or to the extent a valuation is not reported by a pricing service, such securities are valued on the basis of quotes from brokers and dealers. Prices obtained from pricing services utilize both dealer-supplied valuations and electronic data processing techniques which take into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data without exclusive reliance upon quoted prices or exchange or over-the- counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. The series may enter into "TBA" (to be announced) purchase commitments to purchase securities for a fixed unit price at a future date. Although the unit price has been established, the principal value has not been finalized. However, the principal amount of the commitments will not fluctuate more than 0.01%. The series holds, and maintains until settlement date, cash or high- grade debt obligations in an amount sufficient to meet the purchase price, or the series may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to settlement date, which is in addition to the risk of decline in the value of the series' other assets. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $66,018 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $12,553 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, real estate investment trusts, wash sales and amortization and accretion on debt securities. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from: Ordinary income $40,022,926 $25,991,652 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $ 86,929,214 Undistributed long-term capital gain 104,568,810 Unrealized appreciation (depreciation) 251,730,921 MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $549,625, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $374. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0129% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to its Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $7,261, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $81,860 which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations were as follows: U.S. government securities $357,904,883 $244,198,704 -------------------------------------------------------------- Investments (non-U.S. government securities) $721,914,667 $496,360,811 -------------------------------------------------------------- The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $3,270,463,463 ------------------------------------------------------ Gross unrealized appreciation $247,505,551 Gross unrealized depreciation (67,773,698) ------------------------------------------------------ Net unrealized appreciation (depreciation) $179,731,853 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $11,495 and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005. (7) FINANCIAL INSTRUMENTS The series trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include forward foreign currency exchange contracts. The notional or contractual amounts of these instruments represent the investment the series has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. There were no outstanding financial instruments with off-balance-sheet risk at the end of the period.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security is considered Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed securities, if any, are included in a "AAA"-rating category. Percentages are based on the total market value of investments as of 6/ 30/05. *** The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre-refunded to an earlier date or which have a mandatory put date prior to the stated maturity. The average life shown takes into account these earlier dates. **** The Portfolio Average Credit Quality rating is based upon a market weighted average of portfolio holdings. Percentages are based on net assets as of 6/30/05, unless otherwise noted. The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.90% $1,000.00 $1,011.20 $4.49 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.90% $1,000.00 $1,020.33 $4.51 - ------------------------------------------------------------------------------- Actual 1.15% $1,000.00 $1,008.50 $5.73 Service ----------------------------------------------------------------------- Class Hypothetical* 1.15% $1,000.00 $1,019.09 $5.76 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Variable Insurance Trust - MFS Strategic Income Series (the series) is a non-diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 35 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Bonds and other fixed income securities (other than short-term obligations) in the series' portfolio are valued at an evaluated bid price as reported by an independent pricing service, or to the extent a valuation is not reported by a pricing service, such securities are valued on the basis of quotes from brokers and dealers. Prices obtained from pricing services utilize both dealer-supplied valuations and electronic data processing techniques which take into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data without exclusive reliance upon quoted prices or exchange or over-the- counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Futures contracts are valued at the settlement price as reported by an independent pricing service on the primary exchange on which they are traded. Forward foreign currency contracts are valued using spot rates and forward points as reported by an independent pricing source. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. FUTURES CONTRACTS - The series may enter into futures contracts for the delayed delivery of securities or currency, or contracts based on financial indices at a fixed price on a future date. In entering such contracts, the series is required to deposit with the broker, either in cash or securities, an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the series each day, depending on the daily fluctuations in the value of the contract, and are recorded for financial statement purposes as unrealized gains or losses by the series. The series' investment in futures contracts is designed to hedge against anticipated future changes in interest or exchange rates or securities prices. Investments in interest rate futures for purposes other than hedging may be made to modify the duration of the portfolio without incurring the additional transaction costs involved in buying and selling the underlying securities. Investments in currency futures for purposes other than hedging may be made to change the series' relative position in one or more currencies without buying and selling portfolio assets. Investments in equity index contracts or contracts on related options for purposes other than hedging, may be made when the series has cash on hand and wishes to participate in anticipated market appreciation while the cash is being invested. Should interest or exchange rates or securities prices move unexpectedly, the series may not achieve the anticipated benefits of the futures contracts and may realize a loss. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The series 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 into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The series may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the series may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The series may also use contracts in a manner intended to protect foreign currency-denominated securities from declines in value due to unfavorable exchange rate movements. For non-hedging purposes, the series may enter into contracts with the intent of changing the relative exposure of the series' portfolio of securities to different currencies to take advantage of anticipated changes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until the contract settlement date. On contract settlement date, the gains or losses are recorded as realized gains or losses on foreign currency transactions. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. The series may enter into "TBA" (to be announced) purchase commitments to purchase securities for a fixed unit price at a future date. Although the unit price has been established, the principal value has not been finalized. However, the principal amount of the commitments will not fluctuate more than 0.01%. The series holds, and maintains until settlement date, cash or high- grade debt obligations in an amount sufficient to meet the purchase price, or the series may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to settlement date, which is in addition to the risk of decline in the value of the series' other assets. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities. The series may enter into "TBA" (to be announced) sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, equivalent deliverable securities, or an offsetting TBA purchase commitment deliverable on or before the sale commitment date, are held as "cover" for the transaction. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. This amount, for the six months ended June 30, 2005, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, straddle loss deferrals, derivatives, wash sales, and amortization and accretion on debt securities. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from: Ordinary income $2,377,974 $2,408,613 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $2,564,253 Undistributed long-term capital gain1 34,125 Unrealized appreciation (depreciation) 1,983,006 Other temporary differences (676,982) MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.15% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $6,686, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $236. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0142% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons, and pays no compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $88, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than purchased option transactions and short-term obligations, were as follows: PURCHASES SALES U.S. government securities $4,104,837 $2,783,481 ------------------------------------------------------------ Investments (non-U.S. government securities) $12,898,004 $12,036,909 ------------------------------------------------------------ The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $37,177,511 ------------------------------------------------------ Gross unrealized appreciation $1,110,079 Gross unrealized depreciation (455,720) ------------------------------------------------------ Net unrealized appreciation (depreciation) $654,359 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 256,324 $2,809,918 604,373 $6,619,896 Shares issued to shareholders in reinvestment of distributions 224,075 2,319,173 175,706 1,839,639 Shares reacquired (415,770) (4,541,318) (1,041,132) (11,244,960) - --------------------------------------------------------------------------------------------------------------------------------- Net change 64,629 $587,773 (261,053) $(2,785,425) SERVICE CLASS SHARES Shares sold 154,848 $1,680,142 295,864 $3,199,156 Shares issued to shareholders in reinvestment of distributions 37,190 381,201 51,913 538,335 Shares reacquired (31,060) (331,067) (777,967) (8,088,417) - --------------------------------------------------------------------------------------------------------------------------------- Net change 160,978 $1,730,276 (430,190) $(4,350,926) (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $128, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005. (7) FINANCIAL INSTRUMENTS The series trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include forward foreign currency exchange contracts and futures contracts.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.91% $1,000.00 $978.40 $4.46 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.91% $1,000.00 $1,020.28 $4.56 - ------------------------------------------------------------------------------- Actual 1.16% $1,000.00 $976.90 $5.69 Service ----------------------------------------------------------------------- Class Hypothetical* 1.16% $1,000.00 $1,019.04 $5.81 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Investors Growth Stock Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 52 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005, the series' custodian fees were reduced by $10,654 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005, the series' miscellaneous expenses were reduced by $13,162 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, wash sales, and non-taxable distributions. The series paid no distributions for the years ended December 31, 2004 and December 31, 2003. As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $1,109,562 Capital loss carryforward (75,867,202) Unrealized appreciation (depreciation) 28,518,480 Other temporary differences (5,074) For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2009, ($14,413,014) and December 31, 2010, ($61,454,188). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with MFS to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $79,759, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $555. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0142% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $1,058, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $224,255, which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. The receivable from investment adviser represents certain expenses to be reimbursed to the series as a result of an expense adjustment. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $265,371,369 and $285,781,530, respectively.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.91% $1,000.00 $1,082.30 $4.70 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.91% $1,000.00 $1,020.28 $4.56 - ------------------------------------------------------------------------------- Actual 1.17% $1,000.00 $1,081.10 $6.04 Service ----------------------------------------------------------------------- Class Hypothetical* 1.17% $1,000.00 $1,018.99 $5.86 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Utilities Series (the series) is a non-diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 89 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Bonds and other fixed income securities (other than short-term obligations) in the series' portfolio are valued at an evaluated bid price as reported by an independent pricing service, or to the extent a valuation is not reported by a pricing service, such securities are valued on the basis of quotes from brokers and dealers. Prices obtained from pricing services utilize both dealer-supplied valuations and electronic data processing techniques which take into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data without exclusive reliance upon quoted prices or exchange or over-the- counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. Forward foreign currency contracts are valued using spot rates and forward points as reported by an independent pricing source. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the series to certain qualified institutions (the "Borrowers") approved by the series. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the series with indemnification against Borrower default. The series bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the series and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the series and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The series 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 into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The series may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the series may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The series may also use contracts in a manner intended to protect foreign currency- denominated securities from declines in value due to unfavorable exchange rate movements. For non-hedging purposes, the series may enter into contracts with the intent of changing the relative exposure of the series' portfolio of securities to different currencies to take advantage of anticipated changes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until the contract settlement date. On contract settlement date, the gains or losses are recorded as realized gains or losses on foreign currency transactions. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. This amount, for the six months ended June 30, 2005, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, defaulted bonds, wash sales, foreign capital gains tax, and amortization and accretion on debt securities. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from ordinary income $5,413,266 $5,630,290 -------------------------------------------------------- As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $4,113,997 Capital loss carryforward (58,679,984) Unrealized appreciation (depreciation) 86,108,079 Other temporary differences (275,033) For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2010. Realized gain is reported net of any foreign capital gains tax in the Statement of Operations. MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with MFS to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $116,660, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $272. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0143% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $1,533, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. The series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. On July 28, 2004, the series accrued an estimate of the amount to be received pursuant to this matter in the amount of $38,231, which did not have a material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded. The proceeds were paid to the series on February 16, 2005. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $411,239,178 and $243,780,564, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $770,786,350 -------------------------------------------------- Gross unrealized appreciation $98,590,119 Gross unrealized depreciation (6,617,771) -------------------------------------------------- Net unrealized appreciation (depreciation) $91,972,348 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 3,327,008 $69,299,096 4,860,270 $85,737,176 Shares issued to shareholders in reinvestment of distributions 120,622 2,451,031 236,215 3,845,578 Shares reacquired (1,649,476) (34,171,886) (2,858,685) (48,806,414) - ------------------------------------------------------------------------------------------------------------------------------- Net change 1,798,154 $37,578,241 2,237,800 $40,776,340 SERVICE CLASS SHARES Shares sold 6,889,004 $142,244,422 6,155,714 $108,396,221 Shares issued to shareholders in reinvestment of distributions 82,376 1,663,988 96,771 1,567,688 Shares reacquired (731,979) (15,108,935) (1,414,523) (24,005,078) - ------------------------------------------------------------------------------------------------------------------------------- Net change 6,239,401 $128,799,475 4,837,962 $85,958,831 (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $2,587, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005. (7) FINANCIAL INSTRUMENTS The series trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include forward foreign currency exchange contracts. The notional or contractual amounts of these instruments represent the investment the series has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. Forward Foreign Currency Exchange Contracts Sales and purchases in the table below are netted by currency.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.90% $1,000.00 $1,005.00 $4.47 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.90% $1,000.00 $1,020.28 $4.51 - ------------------------------------------------------------------------------- Actual 1.15% $1,000.00 $1,004.90 $5.72 Service ----------------------------------------------------------------------- Class Hypothetical* 1.15% $1,000.00 $1,019.04 $5.76 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS High Income Series (the series) is a diversified series of MFS Variable Insurance Trust (the Trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 33 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest up to 100% of its portfolio in high-yield securities rated below investment grade. Investments in high-yield securities involve greater degrees of credit and market risk than investments in higher-rated securities and tend to be more sensitive to economic conditions. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Bonds and other fixed income securities (other than short-term obligations) in the series' portfolio are valued at an evaluated bid price as reported by an independent pricing service, or to the extent a valuation is not reported by a pricing service, such securities are valued on the basis of quotes from brokers and dealers. Prices obtained from pricing services utilize both dealer-supplied valuations and electronic data processing techniques which take into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data without exclusive reliance upon quoted prices or exchange or over-the- counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Forward foreign currency contracts are valued using spot rates and forward points as reported by an independent pricing source. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The series 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 into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The series may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the series may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The series may also use contracts in a manner intended to protect foreign currency- denominated securities from declines in value due to unfavorable exchange rate movements. For non-hedging purposes, the series may enter into contracts with the intent of changing the relative exposure of the series' portfolio of securities to different currencies to take advantage of anticipated changes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until the contract settlement date. On contract settlement date, the gains or losses are recorded as realized gains or losses on foreign currency transactions. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. Legal fees and other related expenses incurred to preserve and protect the value of a security owned are added to the cost of the security; other legal fees are expensed. Capital infusions made directly to the security issuer, which are generally non-recurring, incurred to protect or enhance the value of high-yield debt securities, are reported as additions to the cost basis of the security. Costs that are incurred to negotiate the terms or conditions of capital infusions or that are expected to result in a plan of reorganization are reported as realized losses. Ongoing costs incurred to protect or enhance an investment, or costs incurred to pursue other claims or legal actions, are expensed. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the six months ended June 30, 2005 the series' custodian fees were reduced by $18,566 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the six months ended June 30, 2005 the series' miscellaneous expenses were reduced by $185 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, wash sales, defaulted bonds, and amortization and accretion on debt securities. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from: Ordinary income $18,289,306 $9,048,084 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $27,314,965 Capital loss carryforward (11,058,595) Unrealized appreciation (depreciation) 16,363,595 Other temporary differences (247,279) For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on December 31, 2009 ($2,170,077) and December 31, 2010 ($8,888,518). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with MFS to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.75% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management and distribution and certain other fees and expenses, such that operating expenses do not exceed 0.15% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006 unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005 the fee was $69,852, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005 these costs amounted to $152. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0141% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $927, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $122,849,352 and $155,986,749, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the series, as computed on a federal income tax basis, are as follows: Aggregate cost $361,885,172 ---------------------------------------------------- Gross unrealized appreciation $8,007,106 Gross unrealized depreciation (7,377,803) ---------------------------------------------------- Net unrealized appreciation (depreciation) $629,303 (5) SHARES OF BENEFICIAL INTEREST The series' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

The redeeming shareholder voluntarily reimbursed the series for trading costs incurred on security sales that were required to fund the redemption. (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $2,414 and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005. (7) FINANCIAL INSTRUMENTS The series trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include forward foreign currency exchange contracts. The notional or contractual amounts of these instruments represent the investment the series has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. Forward Foreign Currency Exchange Contracts Sales and purchases in the table below are netted by currency.

(8) RESTRICTED SECURITIES At June 30, 2005, the series owned the following restricted securities which are subject to legal or contractual restrictions on resale, excluding securities issued under Rule 144A, constituting 0.03% of net assets which may not be publicly sold without registration under the Securities Act of 1933. The series does not have the right to demand that such securities be registered. The value of these securities is determined by valuations furnished by dealers or by a pricing service, or if not available, in good faith at the direction of the Trustees.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security is considered Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed securities, if any, are included in a "AAA"-rating category. Percentages are based on the total market value of investments as of 6/ 30/05. *** The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre-refunded to an earlier date or which have a mandatory put date prior to the stated maturity. The average life shown takes into account these earlier dates. **** The Portfolio Average Credit Quality rating is based upon a market weighted average of portfolio holdings. Percentages are based on net assets as of 6/30/05, unless otherwise noted. The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JANUARY 1, 2005 THROUGH JUNE 30, 2005. As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, January 1, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 1/01/05- Share Class Ratio 1/01/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 0.74% $1,000.00 $1,016.00 $3.70 Initial ----------------------------------------------------------------------- Class Hypothetical* 0.74% $1,000.00 $1,021.12 $3.71 - ------------------------------------------------------------------------------- Actual 0.99% $1,000.00 $1,014.90 $4.95 Service ----------------------------------------------------------------------- Class Hypothetical* 0.99% $1,000.00 $1,019.89 $4.96 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year. Effective May 1, 2005, the series' operating expense reduction was increased from 0.15% to 0.20%, and a 0.10% management fee waiver was put in place (as described in Note 3 of the Notes to the Financial Statements). Had these expense reductions been in effect throughout the entire six month period, the annualized expense ratio would have been lower by 0.10% for each share class, and the expenses paid during the period would have been approximately $0.50 lower for each share class.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Research Bond Series (formerly MFS Bond Series) (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 30 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Bonds and other fixed income securities (other than short-term obligations) in the series' portfolio are valued at an evaluated bid price as reported by an independent pricing service, or to the extent a valuation is not reported by a pricing service, such securities are valued on the basis of quotes from brokers and dealers. Prices obtained from pricing services utilize both dealer-supplied valuations and electronic data processing techniques which take into account appropriate factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data without exclusive reliance upon quoted prices or exchange or over-the- counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. Futures contracts are valued at the settlement price as reported by an independent pricing service on the primary exchange on which they are traded. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. FUTURES CONTRACTS - The series may enter into futures contracts for the delayed delivery of securities or currency, or contracts based on financial indices at a fixed price on a future date. In entering such contracts, the series is required to deposit with the broker, either in cash or securities, an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the series each day, depending on the daily fluctuations in the value of the contract, and are recorded for financial statement purposes as unrealized gains or losses by the series. The series' investment in futures contracts is designed to hedge against anticipated future changes in interest or exchange rates or securities prices. Investments in interest rate futures for purposes other than hedging may be made to modify the duration of the portfolio without incurring the additional transaction costs involved in buying and selling the underlying securities. Investments in currency futures for purposes other than hedging may be made to change the series' relative position in one or more currencies without buying and selling portfolio assets. Investments in equity index contracts or contracts on related options for purposes other than hedging, may be made when the series has cash on hand and wishes to participate in anticipated market appreciation while the cash is being invested. Should interest or exchange rates or securities prices move unexpectedly, the series may not achieve the anticipated benefits of the futures contracts and may realize a loss. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. The series may enter into "TBA" (to be announced) purchase commitments to purchase securities for a fixed unit price at a future date. Although the unit price has been established, the principal value has not been finalized. However, the principal amount of the commitments will not fluctuate more than 0.01%. The series holds, and maintains until settlement date, cash or high- grade debt obligations in an amount sufficient to meet the purchase price, or the series may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to settlement date, which is in addition to the risk of decline in the value of the series' other assets. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities. The series may enter into "TBA" (to be announced) sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, equivalent deliverable securities, or an offsetting TBA purchase commitment deliverable on or before the sale commitment date, are held as "cover" for the transaction. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. This amount, for the six months ended June 30, 2005, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Common types of book and tax differences that could occur include differences in accounting for foreign currency transactions, amortization and accretion on debt securities, and wash sales. The tax character of distributions declared for the years ended December 31, 2004 and December 31, 2003 was as follows: 12/31/04 12/31/03 Distributions declared from: Ordinary income $2,012,241 $2,049,079 As of December 31, 2004, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $1,835,267 Undistributed long-term capital gain 310,663 Unrealized appreciation (depreciation) 1,103,191 MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.60% of the series' average daily net assets. Effective May 1, 2005, the investment adviser has contractually agreed to waive 0.10% of its fee, which amounted to $5,915, and is shown as a reduction of total expenses in the Statement of Operations. This reduction in the management fee may be rescinded by MFS only with the approval of the series' Board of Trustees. The management fee incurred for the six months ended June 30, 2005, was equivalent to an annual effective rate of 0.57% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.20% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the six months ended June 30, 2005, the fee was $6,293, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the six months ended June 30, 2005, these costs amounted to $40. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the six months ended June 30, 2005 was equivalent to an annual effective rate of 0.0142% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons, and pays no compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFD, and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $83, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement.

Transactions in series shares were as follows: Six months ended 6/30/05 Year ended 12/31/04 SHARES AMOUNT SHARES AMOUNT INITIAL CLASS SHARES Shares sold 225,726 $2,659,162 436,249 $5,236,287 Shares issued to shareholders in reinvestment of distributions 144,419 1,653,593 157,450 1,810,680 Shares reacquired (304,458) (3,613,686) (842,512) (10,045,586) - -------------------------------------------------------------------------------------------------------------------------------- Net change 65,687 $699,069 (248,813) $(2,998,619) SERVICE CLASS SHARES Shares sold 298,800 $3,543,113 357,507 $4,267,940 Shares issued to shareholders in reinvestment of distributions 43,363 494,338 17,573 201,561 Shares reacquired (39,043) (466,822) (32,467) (384,282) - -------------------------------------------------------------------------------------------------------------------------------- Net change 303,120 $3,570,629 342,613 $4,085,219 (6) LINE OF CREDIT The series and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the series for the six months ended June 30, 2005 was $121, and is included in miscellaneous expense. The series had no significant borrowings during the six months ended June 30, 2005. (7) FINANCIAL INSTRUMENTS The series trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include futures contracts. The notional or contractual amounts of these instruments represent the investment the series has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. There were no outstanding financial instruments with off-balance-sheet risk at the end of the period.

Manning] Dear Contract Owners, As a professional investor for more than 20 years, I've often been asked to name the single most important factor in investment success. My answer is always the same: diversification. At MFS we talk about applying a disciplined diversification(SM) strategy to a portfolio as a three step process: allocate among the major asset classes; diversify within each asset class; and rebalance regularly to avoid unnecessary risk. Individual investors sometimes assume that the amount they're putting away is too small to allow for diversification. My response would be that a good investment plan, developed with the help of an investment professional, should provide a way to properly diversify your contributions. Remember that the purpose of diversification is to own investments that historically have not moved in sync with each other - in the hope that, in any given period, underperforming holdings will be somewhat counteracted by other outperforming holdings. If none of your asset classes did badly in the past year or so, you're probably not properly diversified. Americans today have more of their wealth tied up in the markets than in any previous period of our history, but we are not yet making the most of our opportunities. While neither asset allocation nor diversification can guarantee a profit or protect against a loss, I would voice the opinion that, to a large extent, a failure to have a plan, diversify contributions, and rebalance a portfolio annually has been behind many U.S. investors' failure to reach their long-term financial goals. For more information on how to apply a disciplined diversification(SM) strategy to your portfolio, I would urge you to contact your own investment professional. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) August 15, 2005 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

As a shareholder of the series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the series 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, April 29, 2005 through June 30, 2005. ACTUAL EXPENSES The first line for each share class in 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 line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the series' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the series 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 the series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in the series is made. Therefore, the second line for each share class in the table is useful in comparing ongoing costs associated with an investment in vehicles (such as the series) which fund benefits under variable annuity and variable life insurance contracts and to qualified pension and retirement plans only, and will not help you determine the relative total costs of investing in the series through variable annuity and variable life insurance contracts. If the fees and expenses imposed under the variable contracts were included, your costs would have been higher. - ------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Expense Account Value Account Value 4/29/05- Share Class Ratio 4/29/05 6/30/05 6/30/05 - ------------------------------------------------------------------------------- Actual 1.10% $1,000.00 $1,016.00 $1.91 Initial ----------------------------------------------------------------------- Class Hypothetical* 1.10% $1,000.00 $1,006.62 $1.91 - ------------------------------------------------------------------------------- Actual 1.35% $1,000.00 $1,015.00 $2.35 Service ----------------------------------------------------------------------- Class Hypothetical* 1.35% $1,000.00 $1,006.20 $2.34 - ------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Research International Series (the series) is a diversified series of MFS Variable Insurance Trust (the trust). The trust is organized 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 shareholders of each series of the trust are separate accounts of insurance companies, which offer variable annuity and/or life insurance products. As of June 30, 2005, there were 7 shareholders. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The series can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. INVESTMENT VALUATIONS - Equity securities in the series' portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the series' portfolio are valued at amortized cost, which approximates market value as determined by the Board of Trustees. 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. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the series calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the series may utilize information from an external vendor or other sources to adjust closing market quotations of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. REPURCHASE AGREEMENTS - The series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The series requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the series to obtain those securities in the event of a default under the repurchase agreement. The series monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the series under each such repurchase agreement. The series, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. The series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the series. FEES PAID INDIRECTLY - The series' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the period ended June 30, 2005, the series' custodian fees were reduced by $6 under this arrangement. The series has entered into a commission recapture agreement, under which certain brokers will credit the series a portion of the commissions generated, to offset certain expenses of the series. For the period ended June 30, 2005, the series did not recapture commissions. The custody fee reduction is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The series' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The series distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in 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 net realized gains. Realized gain is reported net of any foreign capital gains tax in the Statement of Operations. MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The series offers multiple classes of shares, which differ in their respective distribution fees. All shareholders bear the common expenses of the series based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The series has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.90% of the series' average daily net assets. The investment adviser has contractually agreed to pay a portion of the series' operating expenses, exclusive of management, distribution, and certain other fees and expenses, such that operating expenses do not exceed 0.20% annually of the series' average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until April 30, 2006, unless the series' Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, is the distributor of shares of the series. The Trustees have adopted a distribution plan for the Service Class shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. The series' distribution plan provides that the series will pay MFD distribution fees equal to 0.25% per annum of its average daily net assets attributable to Service Class shares as partial consideration for services performed and expenses incurred by MFD and financial intermediaries (including participating insurance companies that invest in the series to fund variable annuity and variable life insurance contracts, sponsors of qualified retirement and pension plans that invest in the series, and affiliates of these participating insurance companies and plan sponsors) in connection with the sale and distribution of the Service Class shares. SHAREHOLDER SERVICING AGENT - The series pays a portion of shareholder servicing costs to MFSC, a wholly-owned subsidiary of MFS. MFSC receives a fee from the series, for its services as shareholder servicing agent. For the period ended June 30, 2005, the fee was $151, which equated to 0.035% annually of the series' average daily net assets. MFSC also receives payment from the series for out-of-pocket expenses paid by MFSC on behalf of the series. For the period ended June 30, 2005, there were no out-of-pocket expenses. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is allocated a portion of these administrative costs based on its size and relative average net assets. The administrative services fee incurred for the period ended June 30, 2005 was equivalent to an annual effective rate of 0.01441% of the series' average daily net assets. TRUSTEES' COMPENSATION - The series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The series does not pay compensation directly to Trustees who are officers of the investment adviser, or to officers of the series, all of whom receive remuneration for their services to the series from MFS. Certain officers and Trustees of the series are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). OTHER - This series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $2, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $3,059,154 and $223,215, respectively.

BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENT The Investment Company Act of 1940 requires that both the full Board of Trustees and a majority of the non-interested ("independent") Trustees, voting separately, initially approve the series' investment advisory agreement with MFS and annually approve the continuation of the series' investment advisory agreement with MFS. The Trustees consider matters bearing on the series and its advisory arrangements at their meetings throughout the year. In April 2005, the Board met to consider the initial approval of the series' investment advisory agreement ("initial review meeting"). In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July, 2005 (the "renewal meetings," together with the initial review meeting, the "contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreement for the series and the other investment companies that the Board oversees (the "MFS Funds"). The independent Trustees were assisted in their evaluation of the series' investment advisory agreement by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS during various contract review meetings. The independent Trustees were also assisted in this process by the MFS Funds' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations regarding the initial approval and the continuation of the investment advisory agreement, the Trustees, including the independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The investment advisory agreement for the series was considered separately, although the Trustees also took into account the common interests of all MFS Funds in their review. As described below, the Trustees considered the nature, quality, and extent of the various investment advisory, administrative, and shareholder services performed by MFS under the existing investment advisory agreement and other arrangements with the series. The series commenced operations in May, 2005 and has a limited operating history and performance record. In considering investment performance, the Trustees took into account the investment performance of other MFS Funds with comparable investment objectives and policies as the series, including the performance of MFS Research International Fund. In connection with their contract review meetings, the Trustees received and relied upon materials which included, among other items: (i) information provided by Lipper Inc. on the investment performance of funds with substantially similar investment classifications/objectives to the series for various time periods ended December 31, 2004, (ii) information provided by Lipper Inc. on the series' advisory fees and other expenses and the advisory fees and other expenses of comparable funds identified by Lipper (the "Lipper expense group"), as well as the advisory fees and other expenses of peer funds identified by objective criteria suggested by MFS, (iii) information provided by MFS on the advisory fees of comparable portfolios of other clients of MFS, including MFS Institutional International Research Equity Fund and other comparable mutual fund clients of MFS and, in connection with the renewal meetings, institutional separate account and other clients, (iv) information as to whether and to what extent applicable expense waivers, reimbursements or fee "breakpoints" are observed for the series, (v) information regarding MFS' financial results and financial condition, including MFS' and certain of its affiliates' estimated profitability from services performed for the series and the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual fund industry and the strategic business plans of MFS, (vii) descriptions of various functions performed by MFS for the Funds, such as compliance monitoring and portfolio trading practices, and (viii) information regarding the overall organization of MFS, including information about MFS' senior management and other personnel providing investment advisory, administrative and other services to the series and the other MFS Funds. The comparative fee and expense information prepared and provided by Lipper Inc. was not independently verified and the independent Trustees did not independently verify any information provided to them by MFS. The Trustees' conclusion as to the initial approval and the continuation of the investment advisory agreement was based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees' deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. In the course of their deliberations, the Trustees took into account information provided by MFS in connection with the contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that they were satisfied with MFS' efforts relating to investment performance. In assessing the reasonableness of the series' advisory fee, the Trustees considered, among other information, the series' advisory fee and the total expense ratio of the series' Initial Class shares as a percentage of average net assets and the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees considered that MFS currently observes a voluntary expense limitation for the series, which may not be changed without the Trustees' approval. The Trustees also considered that, according to the Lipper data, the series' effective advisory fee rate (taking into account the voluntary expense limitation) and total expense ratio were each lower than the median of such fees and expenses of funds in the Lipper expense group. At the renewal meetings, the Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered information provided by MFS as to the generally broader scope of services provided by MFS to the series in comparison to institutional accounts, the higher demands placed on MFS' investment personnel and trading infrastructure as a result of the daily cash in-flows and out-flows of the series, and the impact on MFS and expenses associated with the more extensive regulatory regime to which the series is subject in comparison to institutional accounts. The Trustees also considered whether the series is likely to benefit from any economies of scale in the management of the series in the event of growth in assets of the series. They noted that the series' advisory fee rate schedule is not currently subject to any breakpoints. Taking into account the expense limitation described above, the Trustees determined not to recommend any advisory fee breakpoints for the series at this time. The Trustees did not consider MFS' costs and profits with respect to the series because the series has no operating history. The Trustees considered information prepared by MFS relating to MFS' costs and profits with respect to the MFS Funds considered as a group, and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the MFS Funds and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described herein, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that the advisory fees charged to the series represent reasonable compensation in light of the nature and quality of the services being provided by MFS to the series. In addition, the Trustees considered MFS' resources and related efforts to continue to retain, attract and motivate capable personnel to serve the series. The Trustees also considered current and developing conditions in the financial services industry, including the entry into the industry of large and well-capitalized companies which are spending, and appear to be prepared to continue to spend, substantial sums to engage personnel and to provide services to competing investment companies. In this regard, the Trustees also considered the financial resources of MFS and its parent, Sun Life Financial Inc. The Trustees also considered the advantages and possible disadvantages to the series of having an adviser which also serves other investment companies as well as other accounts. The Trustees also considered the nature, quality, cost, and extent of administrative, transfer agency, and distribution services provided to the series by MFS and its affiliates under agreements and plans other than the investment advisory agreement, including the 12b-1 fees the series' Service Class shares pays to MFS Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the nature, extent and quality of certain other services MFS performs or arranges for on the series' behalf, including securities lending programs, directed expense payment programs, class action recovery programs, and MFS' interaction with third-party service providers, principally custodians and sub-custodians. The Trustees concluded that the various non-advisory services provided by MFS and its affiliates on behalf of the Funds were satisfactory. The Trustees also considered benefits to MFS from the use of the series' portfolio brokerage commissions to pay for research and other similar services (including MFS' policy not to use "soft dollars" generated by series portfolio transactions to pay for third-party research), and various other factors. Additionally, the Trustees considered so-called "fall-out benefits" to MFS such as reputational value derived from serving as investment manager to the series. Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board of Trustees, including a majority of the independent Trustees, concluded that the series' investment advisory agreement with MFS should be approved commencing in April 2005 and continued for an additional one-year period, commencing August 1, 2005. The discussion regarding the Board's initial approval and recent renewal of the series' Investment Advisory Agreement with MFS can also be found by clicking on "Variable Insurance Trust" in the "Products and Performance" section of the MFS website (mfs.com).
