Still, it is surprising how often we forget these basic lessons. Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s had many people hoping they could become millionaires overnight. But the market decline that started in the spring of 2000 taught everyone how misguided those hopes had been. Now, less than six years after the market taught a harsh lesson in the follies of speculative investing, we are seeing a number of trends that suggest many investors, including professionals, are hoping for overnight miracles again. We see a steady stream of market "gurus" on television news shows, promising to teach amateur investors the strategies that will allow them to get rich quick. Hedge funds - which by their nature move in and out of investments rapidly - have soared in popularity in recent years. We are reminded every day that we live in a "what have you done for me lately?" world, but this mindset should not influence how we invest and manage our money. In fact, investors often fall short of their goals because they traded in and out of investments too frequently and at inopportune times. Throughout our more than 80-year history, MFS' money management process has focused on long-term investment opportunities. We firmly believe that the best way to realize long-term financial goals - be it a college education, a comfortable retirement, or a secure family legacy - is to follow a three- pronged approach that focuses on longer time horizons. Allocate holdings across the major asset classes - including stocks, bonds, and cash. Diversify within each class to take advantage of different market segments and investing styles. And rebalance assets regularly to maintain a desired asset allocation.* This long-term approach requires diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) February 15, 2006 * Asset allocation, diversification, and rebalancing do not guarantee a profit or protect against a loss. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. MANAGEMENT REVIEWS The following management reviews, for the twelve months ended December 31, 2005, exclude the Money Market Series. BOND SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 1.75%, while Service Class shares provided a total return of 1.59%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 2.37% for the series' benchmark, the Lehman Brothers U.S. Government/Credit Bond Index. DETRACTORS FROM PERFORMANCE The portfolio's currency exposure to the euro and the Danish krone detracted from performance. Throughout the period, the U.S. dollar appreciated against most major currencies resulting in losses for any unhedged currency positions. Overweighting "BBB" and "BB"-rated(1) securities acted as a drag on performance. During the period, spreads between corporate bonds and Treasuries widened, decreasing the value of corporate bonds. Other areas that detracted included Treasuries and bonds from the telecommunications sector as these areas lagged the benchmark. CONTRIBUTORS TO PERFORMANCE The portfolio benefited by having a shorter duration(2) than the index, which was advantageous in a rising interest rate environment. The portfolio enjoyed a yield advantage over the period and generated a higher level of income than the index. On a sector basis, strong performance from asset-backed and mortgage-backed securities, along with the debt of emerging markets, contributed to relative results. Despite the downgrading and decrease in value associated with bonds of Ford Motor Credit and General Motors Acceptance Corp, the banking/finance sector performed well and added to returns. EMERGING MARKETS EQUITY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 36.76%, while Service Class shares provided a total return of 36.36%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 34.54% for the series' benchmark, the MSCI Emerging Markets Index. CONTRIBUTORS TO PERFORMANCE Overall stock selection was the primary contributor to the portfolio's performance, led by strong selection in the technology and financial services sectors. Taiwanese wireless device manufacturer High Tech Computer* was the top contributing holding as its shares appreciated significantly over the period. In the financial services sector, the portfolio's positions in banking firms Unibanco-Uniao de Bancos Brasileiros (Brazil) and Akbank (Turkey) boosted relative performance. Security selection in the consumer staples sector also aided results as Brazilian brewer Companhia de Bebidas das Americas posted strong gains. Several individual energy holdings also benefited the portfolio's performance including Russian integrated oil company LUKOIL and global seamless steel pipe manufacturer Tenaris. In other sectors, our positions in South African chemical and fuel company Sasol*, South African wireless network operator MTN Group, and Brazilian Internet retailer Submarino*, which is not a benchmark constituent, were among the portfolio's top contributors for the year. During the reporting period, the portfolio's currency exposure was a contributor to relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. DETRACTORS FROM PERFORMANCE Security selection in the utilities and communications sector was the main detractor from relative performance. Within this sector, the portfolio's holdings in Latin American wireless services provider America Movil* and Brazilian communications company Brasil Telecom Participacoes* hurt results as shares of both rose subsequent to their elimination from the portfolio. Not owning strong-performing benchmark constituent Orascom Telecom Holding, a wireless network operator in the Middle East and Africa, also hindered relative results. Our underweighting of the industrial goods and services sector and stock selection in the leisure sector dampened relative returns. No individual holdings in either sector were among the top detractors from performance. Elsewhere, holdings in Indonesian automaker PT Astra International, Brazilian paper products manufacturer Votorantim Celulose e Papel, Latin American appliance and furniture retailer Grupo Elektra*, and insurance and financial services company Liberty Group* held back results. The portfolio's holdings in benchmark constituent MOL, a Hungarian integrated oil company, also had a negative impact on performance as we missed the significant run-up in share price earlier in the year. The portfolio's cash position was a detractor from relative performance. The portfolio holds cash to buy new holdings and to provide liquidity. In a period when equity markets rose, as measured by the portfolio's benchmark, holding cash hurt performance versus the benchmark, which has no cash position. *Security was not held in the portfolio at period-end. GLOBAL GOVERNMENTS SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of -7.20%, while Service Class shares provided a total return of -7.49%. These returns do not reflect any applicable contract or surrender charges and compare with a return of -6.53% for the series' benchmark, the J.P. Morgan Global Government Bond Index. During the reporting period ended December 31, 2005, the series' benchmark changed from the Citigroup World Government Bond Index to the J.P. Morgan Global Government Bond Index. DETRACTORS FROM PERFORMANCE The portfolio's currency positions acted as a drag on relative performance. During the first half of the period, the portfolio's lower exposure to the U.S. dollar hurt relative results, as the dollar appreciated relative to most major currencies. During the period, the index generated a higher level of income than the portfolio. CONTRIBUTORS TO PERFORMANCE The portfolio's duration(2) stance and yield curve(3) positioning aided relative results throughout the period. The portfolio's positions in longer- term U.S. and European bonds contributed to performance, as long-term interest rates declined in the U.S. and Europe. Holdings of asset-backed bonds, government agencies, and bonds in the finance sector also bolstered results. Holdings in emerging market debt added to performance, driven primarily by Russian and Mexican bond positions. GLOBAL TOTAL RETURN SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 3.83%, while Service Class shares provided a total return of 3.54%. These returns, which do not reflect any applicable contract or surrender charges, compare with a return of 10.02% for the series' benchmark, the MSCI World Index. The series' other benchmark, a blended benchmark comprised of 60% MSCI World Index and 40% J.P. Morgan Global Government Bond Index, provided a return of 2.90%. The J.P. Morgan Global Government Bond Index provided a return of -6.53%. During the period ended December 31, 2005, the series' benchmark changed from the Standard & Poor's 500 Stock Index to the MSCI World Index. DETRACTORS FROM PERFORMANCE Within the equity portion of the series, stock selection within the financial services sector detracted from performance relative to the MSCI World Index. Within the sector, an overweighted position in poor-performing mortgage giant Fannie Mae held back results. Stock selection was also challenging in the basic materials sector. Holdings in paper manufacturer International Paper and chemicals company PPG Industries detracted from performance relative to the MSCI World Index. Elsewhere, telecommunications firms Vodafone Group and Deutsche Telekom weighed on results as both stocks underperformed the index. Other detractors included Premiere AG in the leisure sector and home builder Masco in the autos and housing sector. The cash position in the equity portion of the series was also a detractor from performance relative to the MSCI World Index. The portfolio holds cash to buy new holdings and to provide liquidity. In a period when equity markets rose, as measured by the portfolio's benchmark, holding cash hurt performance versus the benchmark, which has no cash position. During the reporting period, currency exposure in the equity portion of the series detracted from performance relative to the MSCI World Index. All of MFS' equity investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. Within the fixed income portion of the series, currency positions held back performance relative to the J.P. Morgan Global Government Bond Index. During the first half of the period, the portfolio's lower exposure to the U.S. dollar hurt results, as the dollar appreciated relative to most major currencies. During the period, the J.P. Morgan Global Government Bond Index generated a higher level of income than the portfolio. CONTRIBUTORS TO PERFORMANCE Within the equity portion of the series, security selection and an overweighted position in the strong-performing energy sector boosted performance relative to the MSCI World Index. The portfolio's holdings in Statoil*, EnCana, and Unocal* contributed to relative results. Holdings in ConocoPhillips and Tenaris* (not MSCI World Index constituents) also helped. A combination of an underweighted position and strong stock selection in the technology sector contributed to investment results. Holdings in Samsung Electronics aided returns as the stock outperformed the MSCI World Index. Stock selection and, to a lesser extent, an underweighted position within the leisure sector contributed to performance over the period. Within the sector, overweighting Tokyo Broadcasting* added to relative results. Elsewhere, holdings in utilities and communications firm Fortum* contributed to performance relative to the MSCI World Index. Within the fixed income portion of the series, the stance on duration(2) and yield curve(3) positioning boosted results relative to the J.P. Morgan Global Government Bond Index. The portfolio's positions in longer-term U.S. and European bonds contributed to performance, as long-term interest rates declined in the U.S. and Europe. The portfolio's holdings of asset-backed bonds, government agencies, and bonds in the finance sector also bolstered results. Holdings in emerging market debt added to performance, driven primarily by Russian and Mexican bond positions. *Security was not held in the portfolio at period-end. GOVERNMENT SECURITIES SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 2.30%, while Service Class shares provided a total return of 2.01%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 2.63% for the series' benchmark, the Lehman Brothers U.S. Government/Mortgage Bond Index. DETRACTORS FROM PERFORMANCE Holding lower-yielding issues relative to the portfolio's benchmark held back results for the period. Our underweighted position in 30-year mortgage-backed securities, which outperformed comparable-maturity Treasuries, also detracted from relative performance. CONTRIBUTORS TO PERFORMANCE Toward the end of the period, the portfolio's long duration(2) stance versus the benchmark contributed to performance as long-term interest rates declined. HIGH YIELD SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 2.19%, while Service Class shares provided a total return of 1.93%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 2.74% for the series' benchmark, the Lehman Brothers U.S. High-Yield Corporate Bond Index. DETRACTORS FROM PERFORMANCE Several of the portfolio's holdings in the more speculative "CCC"-rated(1) sectors of the high yield market held back relative performance during the period. Holdings that detracted from relative performance included packaging manufacturer Pliant, cable TV operator Charter Communications, electrical contracting and maintenance company Integrated Electrical Services*, independent power producer Calpine*, and auto parts manufacturer Delphi. The portfolio's holdings in brokerage company Refco* also hurt relative returns as the value of the company's debt declined due to its alleged involvement in fraudulent business practices. CONTRIBUTORS TO PERFORMANCE The portfolio's overweighted positions in the debt of commodity chemical companies contributed to relative returns as this sector outperformed the overall index. Attractive supply-demand dynamics, which boosted earnings and cash flows, enabled these companies to decrease leverage. Our position in chemical company Rhodia was among the portfolio's top contributing securities. The portfolio benefited from several individual holdings that performed well during the period, including television broadcaster Paxson Communications and oil and gas company Kerr-McGee. * Security was not held in the portfolio at period-end. INTERNATIONAL VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 15.22%, while Service Class shares provided a total return of 14.86%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 14.02% for the series' benchmark, the MSCI EAFE Index. The portfolio's other benchmark, the MSCI EAFE Value Index, provided a return of 14.39%. CONTRIBUTORS TO PERFORMANCE Stock selection and, to a lesser extent, our overweighting in the strong- performing energy sector was the primary contributor to the portfolio's performance relative to the benchmark. Within this sector, Norwegian oil and gas company Statoil* was the top contributor as the stock posted solid gains for the period. Other energy holdings that aided results included Canadian oil and gas producer EnCana, global seamless steel pipe manufacturer Tenaris*, and French steel tube maker Vallourec, none of which are benchmark constituents. Strong security selection in the utilities and communications sector, led by Finnish energy provider Fortum*, contributed to the portfolio's relative performance. The portfolio's underweighting in the technology sector helped results as the sector's returns lagged that of the overall benchmark. Within technology, South Korean electronics manufacturer Samsung Electronics, which is not a benchmark constituent, was a particularly strong performer, adding to benchmark relative returns. In other sectors, Japanese apparel maker Sanyo Shokai and UK-based airline operator easyJet*, neither of which are benchmark constituents, boosted relative returns. Japanese commercial broadcaster Tokyo Broadcasting Systems* was the top contributing stock to relative performance. During the reporting period, the portfolio's currency exposure was a contributor to relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. DETRACTORS FROM PERFORMANCE A combination of security selection and underweighted positions in the strong- performing basic materials and industrial goods and services sectors held back performance relative to the benchmark. No individual securities in either sector were among the portfolio's top detractors during the period. Stock selection in the autos and housing sector also hurt benchmark relative performance. No individual securities in this sector were among the portfolio's greatest detractors. Although the utilities and communications and the technology sectors were top contributing sectors over the period, several individual holdings in both sectors hindered performance. These included UK-based wireless service provider Vodafone Group and German telecommunications company Deutsche Telekom in the former sector, and Japanese electronic devices manufacturer Seiko Epison in the latter sector. Among the portfolio's holdings, German pay-television operator Premiere had the greatest negative impact on returns as the stock significantly underperformed the benchmark. Elsewhere, positions in North American frozen dessert maker CoolBrands International and UK supermarket chain William Morrison Supermarkets, neither of which are benchmark constituents, detracted from relative results. The portfolio's cash position was also a detractor from relative performance. The portfolio holds cash to buy new holdings and to provide liquidity. In a period when equity markets rose, as measured by the portfolio's benchmark, holding cash hurt performance versus the benchmark, which has no cash position. * Security was not held in the portfolio at period-end. STRATEGIC INCOME SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 1.89%, while Service Class shares provided a total return of 1.61%. These returns do not reflect any applicable contract or surrender charges and compare with the following returns over the same period for the series' benchmarks: 10.73% for the J.P. Morgan Emerging Markets Bond Index Global, 2.74% for the Lehman Brothers U.S. High-Yield Corporate Bond Index, 5.69% for the Citigroup World Government Bond Non-Dollar Hedged Index, and 2.43% for the Lehman Brothers U.S. Aggregate Bond Index. DETRACTORS FROM PERFORMANCE The portfolio's position in weak-performing "BB"- and "BBB"-rated(1) securities held back performance during the period. The portfolio's foreign currency exposure also detracted from results as the U.S. dollar was strong versus most developed market currencies throughout the year. Among individual holdings, packaging company Pliant was among the portfolio's top detractors for the period. CONTRIBUTORS TO PERFORMANCE The portfolio's duration(2) stance boosted investment results as short-term rates rose during the period. The portfolio's positioning along the yield curve(3) and our holdings of some emerging market sovereign bonds from the governments of Brazil, Russia, and Panama also contributed to performance.

NOTES TO PERFORMANCE SUMMARY Initial Class shares have no sales charge. Service Class shares have no sales charge and carry a 0.25% annual Rule 12b-1 fee. Service Class share performance includes the performance of Initial Class shares for periods prior to the inception of Service Class shares (blended performance). These blended performance figures have not been adjusted to take into account differences in the class-specific operating expenses (such as Rule 12b-1 fees). Because operating expenses of Service Class shares are generally higher than those of Initial Class shares, the blended Service Class shares performance shown is higher than it would have been had Service Class shares been offered for the entire period. Performance results reflect any applicable expense subsidies and waivers in ffect during the periods shown; without these the results would have been less favorable. See the prospectus for details. All results are historical and assume the reinvestment of any dividends and capital gains distributions. Money Market Series performance results reflect any applicable expense subsidies, waivers and adjustments in effect during the periods shown. Subsidies and fee waivers may be imposed to enhance a portfolio's yield during periods when the portfolio's operating expenses have a significant impact on the portfolio's yield due to lower interest rates. Without such subsidies, waivers and adjustments, the results would have been less favorable. See the prospectus for details. All results are historical and assume the reinvestment of dividends and capital gains. The returns for the series shown do not reflect the deduction of expenses associated with variable products, such as mortality and expense risk charges, separate account charges, and sales charges imposed by insurance company separate accounts. Such expenses would reduce the overall returns shown. From time to time the series may receive proceeds from litigation settlements, without which performance would be lower. KEY RISK CONSIDERATIONS BOND SERIES The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Mortgage securities are subject to prepayment risk which can offer less potential for gains in a declining interest rate environment and greater potential for loss in a rising interest rate environment. Derivatives involve risks different from, and greater than, those of the underlying indicator(s) in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. Foreign investments can be more volatile than U.S. investments. EMERGING MARKET EQUITY SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. Changes in currency exchange rates may affect the portfolio's net asset value. The value of dividends and interest earned, and gains and losses realized on the sale of securities. Because MFS may invest a relatively large percentage of the portfolio's assets in issuers located in a single country or a small number of countries, the portfolio's performance could be closely tied to the market, economic, political or regulatory conditions and developments in those countries and could be more volatile than the performance of more geographically diversified portfolios. GLOBAL GOVERNMENTS SERIES The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Mortgage securities are subject to prepayment risk which can offer less potential for gains in a declining interest rate environment and greater potential for loss in a rising interest rate environment. Derivatives involve risks different from, and greater than, those of the underlying indicator(s) in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. Because MFS may invest a relatively large percentage of the portfolio's assets in issuers located in a single country or a small number of countries, the portfolio's performance could be closely tied to the market, economic, political or regulatory conditions and developments in those countries and could be more volatile than the performance of more geographically diversified portfolios. Foreign investments can be more volatile than U.S. investments. Changes in currency exchange rates may affect the portfolio's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. Because the portfolio is considered non-diversified, MFS may invest a significant percentage of the portfolio's assets in a single issuer or a small number of issuers. GLOBAL TOTAL RETURN SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments.

GOVERNMENT SECURITIES SERIES The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities.

HIGH YIELD SERIES The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Derivatives involve risks different from, and greater than, those of the underlying indicator(s) in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. Lower quality debt securities involve substantially greater risk of default and their value can decline significantly over time. Foreign investments can be more volatile than U.S. investments. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. INTERNATIONAL VALUE SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments.

Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. Because MFS may invest a relatively large percentage of the portfolio's assets in issuers located in a single country or a small number of countries, the portfolio's performance could be closely tied to the market, economic, political or regulatory conditions and developments in those countries and could be more volatile than the performance of more geographically diversified portfolios. Value stocks may perform differently from the general stock market and can continue to be undervalued for long periods of time and not realize their full value. MONEY MARKET SERIES The portfolio's yield changes daily and is are based on changes in interest rates and market conditions, and in response to other economic, political, or financial developments. The value of the portfolio's investments may fluctuate in response to many factors including the performance and valuation of the issuer and general market conditions. Foreign investments can be more volatile than U.S. investments. The value of the portfolio's domestic investments will fluctuate. Investors should note that while securities issued by certain U.S. government agencies or instrumentalities are guaranteed by the U.S. government, securities issued by many U.S. government agencies are not guaranteed by the U.S. government. Although the portfolio(s) seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the portfolio. STRATEGIC INCOME SERIES The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Mortgage securities are subject to prepayment risk which can offer less potential for gains in a declining interest rate environment and greater potential for loss in a rising interest rate environment. Derivatives involve risks different from, and greater than, those of the underlying indicator(s) in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. Lower quality debt securities involve substantially greater risk of default and their value can decline significantly over time. Foreign investments can be more volatile than U.S. investments. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. When you sell your units, they may be worth more or less than the amount you paid for them. Please see the prospectus for further information regarding these and other risks considerations. EXPENSE TABLES SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JULY 1, 2005 THROUGH DECEMBER 31, 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, July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The first line for each share class in the following tables 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 following tables 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 tables 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 tables 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.

See notes to financial statements. MFS/SUN LIFE SERIES TRUST NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION 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 consisting of twenty-eight separate series (the series) of shares: Bond Series*, Capital Appreciation Series, Capital Opportunities Series, Core Equity Series, Emerging Growth Series, Emerging Markets Equity Series*, Global Governments Series*, Global Growth Series, Global Total Return Series*, Government Securities Series*, High Yield Series*, International Growth Series, International Value Series*, Massachusetts Investors Growth Stock Series, Massachusetts Investors Trust Series, Mid Cap Growth Series, Mid Cap Value Series, Money Market Series*, New Discovery Series, Research Series, Research International Series, Strategic Growth Series, Strategic Income Series*, Strategic Value Series, Technology Series, Total Return Series, Utilities Series and Value Series. The shares of each series are sold only to variable accounts established by Sun Life Assurance Company of Canada (U.S.) and Sun Life Insurance and Annuity Company of New York to fund benefits under variable contracts issued by such companies. The series denoted with an asterisk above are included within these financial statements. (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. High Yield 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. Certain series can invest in foreign securities, including securities of emerging market issuers. 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. The markets of emerging markets countries are generally more volatile than the markets of developed countries with more mature economies. All of the risks of investing in foreign securities previously described are heightened when investing in emerging markets countries. Investment Valuations - Money market instruments are valued at amortized cost, which approximates market value. Amortized cost involves valuing an instrument at its cost as adjusted for amortization of premium or accretion of discount rather than its current market value. Each money market fund's use of amortized cost is subject to the fund's compliance with Rule 2a-7 of the Investment Company Act of 1940. The amortized cost value of an instrument can be different from the market value of an instrument. Equity securities, including restricted equity securities, are generally valued at the last sale or official closing price as reported by an independent pricing service on the market or exchange on which they are primarily traded. For securities for which there were no sales during the day, equity securities are generally valued at the last quoted bid price as reported by an independent pricing service on the market or exchange on which they are primarily traded. Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated bid price as reported by an independent pricing service. Values of debt instruments obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques which take into account 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. Short- term instruments with a maturity at issuance of 365 days or less are generally valued at amortized cost, which approximates market value. Exchange-traded options are generally valued at the last sale or closing price as reported by an independent pricing service on the exchange on which they are primarily traded. For exchange-traded options in which there were no sales during the day, exchange-traded options are generally valued at the last quoted bid price as reported by an independent pricing service on the exchange on which they are primarily traded. Options not traded on an exchange are generally valued as reported by an independent pricing service or on the basis of quotations obtained from brokers and dealers. Foreign currency options are generally valued using an external pricing model that uses market data from an independent source. Futures contracts are generally valued at settlement price as reported by an independent pricing service on the exchange on which they are primarily traded. For futures contracts in which there were no sales during the day, futures contracts are generally valued at the last quoted bid price as reported by an independent pricing service on the exchange on which they are primarily traded. Forward foreign currency contracts are generally valued at the mean of bid and asked prices based on rates reported by an independent pricing service. Swaps are generally valued on the basis of quotations from brokers and dealers. Open-end investment companies are generally valued at their net asset value per share. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued on the basis of information from brokers and dealers. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars based upon exchange rates provided by an independent source. 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, in valuing securities that trade principally on foreign markets, events reasonably determined to be significant (such as certain movements 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 series' valuation time 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 prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Fair valuation of foreign equity securities may occur frequently based on an assessment that events which occur on a fairly regular basis (such as U.S. market movements) are significant. Repurchase Agreements - Each 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. Each 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. Each 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. Inflation-Adjusted Debt Securities - Certain series invest in inflation- adjusted debt securities issued by the U.S. Treasury. Certain series may also invest in inflation-adjusted debt securities issued by U.S. Government agencies and instrumentalities other than the U.S. Treasury and by other entities such as U.S. and foreign corporations and foreign governments. The principal value of these debt securities is adjusted by references to changes in the Consumer Price Index or another general price or wage index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation. 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. Derivative Risk - Each series may invest in derivatives for hedging or non- hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When each series uses derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include written options, purchased options, forward foreign currency exchange contracts, swap agreements, short sales, and futures contracts. Purchased Options - Each series may purchase call or put options for a premium. Purchasing call options may be a hedge against an anticipated increase in the dollar cost of securities to be acquired or to increase the series' exposure to the underlying instrument. Purchasing put options may hedge against a decline in the value of portfolio securities. The premium paid is included as an investment in the Statement of Assets and Liabilities and is subsequently adjusted to the current value of the option. Premiums paid for purchased options which have expired are treated as realized losses on investments in the Statement of Operations. Premiums paid for purchased options which are exercised or closed are added to the amount paid or offset against the proceeds on the underlying security or financial instrument to determine the realized gain or loss. The risk of loss associated with purchased options is limited to the premium paid. Futures Contracts - Each 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, each 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 each 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. Upon entering into such contracts, each series bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, each series may not achieve the anticipated benefits of the futures contracts and may realize a loss. Forward Foreign Currency Exchange Contracts - Each 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 the contract. Each series may enter into forward foreign currency exchange contracts for hedging purposes as well as for non- hedging purposes. For hedging purposes, each series may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. Each 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, each 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. Swap Agreements - Each series may enter into swap agreements. A swap is an exchange of cash payments between the series and another party. Net cash payments are exchanged at specified intervals and are recorded as a realized gain or loss in the Statement of Operations. The value of the swap is adjusted daily and the change in value is recorded as unrealized appreciation or depreciation in the Statement of Operations. Risks may arise upon entering into these agreements from the potential inability of counterparties to meet the terms of their contract and from unanticipated changes in the value of the financial index on which the swap agreement is based. Each series may enter into credit default swaps to limit or to reduce risk exposure of the series to defaults of corporate and sovereign issuers. The series may also use credit default swaps to create direct or synthetic short or long exposure to domestic or foreign corporate debt securities or certain sovereign debt securities to which the series is not otherwise exposed. In a credit default swap, one party makes a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party, such as a corporate issuer or foreign issuer, on its obligation. 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 certain 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 certain series with indemnification against Borrower default. Each 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. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. Dollar Roll Transactions - Certain series enter into dollar roll transactions, with respect to mortgage backed securities issued by Ginnie Mae, Fannie Mae, and Freddie Mac, in which the series sells mortgage backed securities to financial institutions and simultaneously agrees to accept substantially similar (same type, coupon, and maturity) securities at a later date at an agreed-upon price. During the period between the sale and repurchase in a dollar roll transaction the series will not be entitled to receive interest and principal payments on the securities sold but is compensated by interest earned on the proceeds of the initial sale and by a lower purchase price on the securities to be repurchased which enhances the series' total return. Each series accounts for dollar roll transactions as purchases and sales. If certain criteria are met these dollar roll transactions may be considered a financing transaction whereby the difference in the sales price and the future purchase price is recorded as an adjustment to interest income. Investment Transactions and Income - Investment transactions are recorded on the trade date. Some securities may be purchased on a "when-issued" or "forward delivery" basis, which means that the securities will be delivered to the series at a future date, usually beyond customary settlement time. 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. For Money Market Series, 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. Dividends received in cash are recorded on the ex-dividend date. Certain dividends from foreign securities will be recorded as soon as the series is informed of the dividend if such information is obtained subsequent to 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. Certain series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statements of Operations, or in unrealized gain/loss if the security is still held by the series. Certain 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. Certain 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 - Each series' custody fees are reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the year ended December 31, 2005, certain series' custodian fees were reduced under this arrangement as noted below. Certain series have 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 year ended December 31, 2005, each series' custodian expenses were reduced under this agreement as noted below. These amounts are shown as a reduction of total expenses on the Statements of Operations.

Accordingly, no provision for federal income tax is required in the financial statements. Foreign taxes, if any, have been accrued by each series in the accompanying financial statements. Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statement and tax purposes will reverse at some time in the future. Distributions in excess of net investment income or net realized gains are temporary over distributions for financial statement purposes resulting from differences in the recognition or classification of income for financial statement and tax purposes. Book/tax differences primarily relate to net operating losses, amortization and accretion of debt securities, defaulted bonds, passive foreign investment companies, wash sale loss deferrals, straddle loss deferrals, foreign currency transactions and derivative transactions. The tax character of distributions declared to shareholders is as follows: Emerging Markets Bond Series Equity Series Global Governments Series --------------------------- ------------------------ ---------------------------- December 31, December 31, December 31, --------------------------- ------------------------ --------------------------- 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ....... $ 14,157,639 $ 15,984,702 $ 488,024 $ 553,290 $ 6,705,443 $ 8,408,856 Long-term capital gain .......... 3,592,851 2,879,247 272,379 -- 96,874 -- ------------ ------------ ------------ ------------ ------------ ------------ Total distributions ........... $ 17,750,490 $ 18,863,949 $ 760,403 $ 553,290 $ 6,802,317 $ 8,408,856 ============ ============ ============ ============ ============ ============ Government Global Total Return Series Securities Series High Yield Series --------------------------- ------------------------ ---------------------------- December 31, December 31, December 31, --------------------------- ------------------------ --------------------------- 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ...... $ 10,130,137 $ 4,172,790 $ 31,699,880 $ 40,795,150 $ 31,907,573 $ 31,912,516 Long-term capital gain .......... 8,623,607 -- -- -- -- -- ------------ ------------ ------------ ------------ ------------ ------------ Total distributions ........... $ 18,753,744 $ 4,172,790 $ 31,699,880 $ 40,795,150 $ 31,907,573 $ 31,912,516 ============ ============ ============ ============ ============ ============ International Value Series MoneyMarket Series Strategic Income Series --------------------------- ------------------------ ---------------------------- December 31, December 31, December 31, --------------------------- ------------------------ --------------------------- 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ...... $ 1,161,124 $ 542,884 $ 9,660,955 $ 3,275,930 $ 6,201,359 $ 4,577,175 Long-term capital gain .......... 2,077,175 -- -- -- 625,839 -- ------------ ------------ ------------ ------------ ------------ ------------ Total distributions ........... $ 3,238,299 $ 542,884 $ 9,660,955 $ 3,275,930 $ 6,827,198 $ 4,577,175 ============ ============ ============ ============ ============ ============ As of December 31, 2005, the federal tax cost and the tax basis components of distributable earnings were as follows: Emerging Global Bond Markets Equity Governments Series Series Series - ------------------------------------------------------------------------------------------------- Cost of investments ................................ $217,660,144 $ 77,475,966 $ 52,938,467 ------------ ------------ ------------ Gross appreciation ................................. $ 3,108,710 $ 25,010,704 $ 267,292 Gross depreciation .................................

Multiple Classes of Shares of Beneficial Interest - Each 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 - Each 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 based on a percentage of each series' average daily net assets as follows: Bond Series: The management fee is 0.60% of average daily net assets. Emerging Markets Equity Series: The management fee is 1.05% of the first $500 million of average daily net assets and 1.00% of average daily net assets in excess of $500 million. Global Governments Series: The management fee is 0.75% of the first $300 million of average daily net assets and 0.675% of average daily net assets in excess of $300 million. Global Total Return Series: The management fee is 0.75% of the first $300 million of average daily net assets and 0.675% of average daily net assets in excess of $300 million. Government Securities Series: Prior to September 1, 2005 the management fee was 0.55% of the series' average daily net assets. Effective September 1, 2005, the management fee is 0.55% of the first $1 billion of average daily net assets and 0.50% of average daily net assets in excess of $1 billion. High Yield Series: The management fee is 0.75% of average daily net assets. The investment adviser has contractually agreed to waive its fee to 0.70% of average daily net assets in excess of $1 billion. This reduction of the management fee may be rescinded by MFS only with the approval of the series' Board of Trustees. International Value Series: The management fee is 0.90% of the first $1 billion of average daily net assets, 0.80% of the next $1 billion of average daily net assets and 0.70% of average daily net assets in excess of $2 billion. Money Market Series: The management fee is 0.50% of average daily net assets. The investment adviser has contractually agreed to waive its fee to 0.45% of average daily net assets in excess of $500 million. This reduction of the management fee may be rescinded by MFS only with the approval of the series' Board of Trustees. Strategic Income Series: Prior to September 1, 2005 the management fee was 0.75% of the series' average daily net assets. Effective September 1, 2005, the management fee is 0.75% of the first $1 billion of average daily net assets and 0.65% of average daily net assets in excess of $1 billion. The investment adviser has contractually agreed to waive its fee to 0.65% of average daily net assets in excess of $500 million for the period September 1, 2005, through April 30, 2007. This reduction of the management fee may be rescinded by MFS only with the approval of the series' Board of Trustees. The investment adviser has agreed to pay a portion of certain series' total operating expenses, exclusive of certain fees and expenses, such that the operating expenses of these series do not exceed the expense limitations indicated below, based on the average daily net assets of such series. For the year ended December 31, 2005, this agreement is reflected as a reduction of total expenses in the Statements of Operations for these series. The management fees and expense limitations incurred for the year ended December 31, 2005 were equivalent to an annual effective rate of each series' average daily net assets as follows: Effective Initial Class Service Class Management Expense Expense Fee Limitations Limitations - ------------------------------------------------------------------------------ Bond Series ...................... 0.60% N/A N/A Emerging Markets Equity Series ... 1.05% N/A N/A Global Governments Series ........ 0.75% 1.00%(a) 1.25%(a) Global Total Return Series ....... 0.75% N/A N/A Government Securities Series ..... 0.55% 1.00% 1.25% High Yield Series ................ 0.75% 1.00% 1.25% International Value Series ....... 0.90% N/A N/A Money Market Series .............. 0.50% 0.60%(a) 0.85%(a) Strategic Income Series .......... 0.75% N/A N/A (a) For Global Governments Series and Money Market Series, the expense reduction was $19,764 and $2,087, respectively. 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 each 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 in connection with the sale and distribution of the series' Service Class shares and the sale and distribution of the variable annuity or variable life insurance contracts investing indirectly in Service Class shares. MFD may subsequently pay all, or a portion, of the distribution fees to financial intermediaries. Administrator - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to each series and certain other MFS funds (the 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 year ended December 31, 2005 was equivalent to an annual effective rate of each series' average daily net assets as follows: % of Average Daily Net Assets - ------------------------------------------------------------------- Bond Series ....................................... 0.0176% Emerging Markets Equity Series .................... 0.0178% Global Governments Series ......................... 0.0175% Global Total Return Series ........................ 0.0177% Government Securities Series ...................... 0.0176% High Yield Series ................................. 0.0175% International Value Series ........................ 0.0178% Money Market Series ............................... 0.0170% Strategic Income Series ........................... 0.0176% Trustees' and Officers' Compensation - Each series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to the Board chairperson. Each 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, MFD, and MFS Service Center, Inc. (MFSC). Other - 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 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. For the year ended December 31, 2005, payments made by the series to Tarantino LLC amounted to the following and are included in miscellaneous expense in the Statements of Operations: ICCO Fee - ---------------------------------------------------------------- Bond Series ............................................ $1,096 Emerging Markets Equity Series ......................... 353 Global Governments Series .............................. 293 Global Total Return Series ............................. 864 Government Securities Series ........................... 3,305 High Yield Series ...................................... 1,860 International Value Series ............................. 512 Money Market Series .................................... 1,777 Strategic Income Series ................................ 415 The International Value Series' and Global Total Return Series' investment adviser, MFS, has been the subject of an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. As a result, proceeds in the amount of $942 and $2,205, respectively, were accrued on July 28, 2004 and paid to each series on February 16, 2005.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and the Shareholders of MFS/Sun Life Series Trust: We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of MFS/Sun Life Series Trust (the "Trust"), comprising Bond Series, Emerging Markets Equity Series, Global Governments Series, Global Total Return Series, Government Securities Series, High Yield Series, International Value Series, Money Market Series and Strategic Income Series as of December 31, 2005, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements and financial highlights present fairly, in all material respects, the financial positions of Bond Series, Emerging Markets Equity Series, Global Governments Series, Global Total Return Series, Government Securities Series, High Yield Series, International Value Series, Money Market Series and Strategic Income Series as of December 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

All Trustees currently serve as Trustees of the Series and have served in that capacity since originally elected or appointed. All of the Trustees are also Managers of the Compass Variable Accounts. The executive officers of the MFS Sun Life Series Trust hold similar offices for the Compass Variable Accounts and other funds in the MFS fund complex. Each Trustee serves as a Trustee or Manager of 34 Accounts/Series. The Statement of Additional Information contains further information about the Trustees and is available without charge upon request by calling 1-800-752-7215. BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENTS 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, annually approve the continuation of the Trust's investment advisory agreements with Massachusetts Financial Services Company (MFS) on behalf of the Series. The Trustees consider matters bearing on the Series and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July 2005 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreements for the Series. The independent Trustees were assisted in their evaluation of the investment advisory agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS management during various contract review meetings. The independent Trustees were also assisted in this process by the Series' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations, 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 agreements were considered separately for each Series, although the Trustees also took into account the common interests of all Series 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 agreements and other arrangements with the Trust. 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 each Series for various time periods ended December 31, 2004, compared to the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("peer funds"), (ii) information provided by Lipper Inc. on each Series' advisory fees and other expenses compared to 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 its other clients, including 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 a 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, (vi) MFS' views regarding the outlook for the mutual fund industry and its strategic business plans, (vii) descriptions of various functions performed by MFS for the Trust, 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. The comparative performance, 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 continuation of the investment advisory agreements was based on 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 for each Series, while individual Trustees may have given different weight to various factors and evaluated the information presented as a whole differently than another Trustee. The Trustees recognized that the fee arrangements for the Series reflect years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees compared each Series' total return investment performance to the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of each Series' Initial Class shares in comparison to the performance of funds in its Lipper performance universe over the one-, three- and five-year periods. The Trustees did not rely on performance results for more recent periods, including those shown elsewhere in this report. In the course of their deliberations, the Trustees took into account information provided by MFS during contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year. For Series whose performance lagged their peer groups, they discussed MFS' efforts to improve such Series' performance. After reviewing this information, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreements, that they were satisfied with MFS' responses and efforts relating to investment performance. In assessing the reasonableness of each Series' advisory fee, the Trustees considered, among other information, each Series' advisory fee and the total expense ratio of the Series' Initial Class shares as a percentage of average net assets, compared to the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered the generally broader scope of services provided by MFS to the Trust than those provided to institutional accounts. The Trustees also considered 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 related expenses due to the more extensive regulatory regime to which the Series are subject, compared to institutional accounts. The Trustees also considered whether a Series is likely to benefit from any economies of scale due to future asset growth. In this regard, the Trustees reviewed the adequacy of breakpoints, and considered if breakpoints should be implemented for any Series that did not have them. The Trustees also considered information prepared by MFS relating to its costs and profits with respect to the Series and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the Series and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described below, the Trustees concluded 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. 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 the financial resources of MFS and its affiliation with Sun Life Financial Inc. The Trustees further considered any advantages and possible disadvantages of having an adviser which also serves other investment companies as well as institutional 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 agreements, including the 12b-1 fees the Series pay 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 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 Series were satisfactory. The Trustees also considered the benefits to MFS from the use of the Series' portfolio brokerage commissions to pay for research and other similar services (including MFS' current 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 Trust, and determined that any such benefits derived by MFS were reasonable and fair. Based on their evaluation of factors that they deemed to be material, including those factors described above, and the individual Series factors noted below, the Board of Trustees, including a majority of the independent Trustees, concluded that the investment advisory agreements should be continued for an additional one-year period, commencing September 1, 2005. BOND SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 10th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 12th percentile for the three-year period and the 11th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was higher than, and total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. They further noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. In light of the relatively small size of the Series, the Trustees concluded the fees were satisfactory without implementing breakpoints. EMERGING MARKETS EQUITY SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 18th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers).

Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was approximately at, and total expense ratio was lower than, the median of such fees and expenses of funds in the Lipper expense group.

The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. GLOBAL GOVERNMENTS SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 38th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers).

The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. GLOBAL TOTAL RETURN SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 7th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers).

Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.05% on net assets over $1 billion, which took effect on September 1, 2005. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. HIGH YIELD SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 54th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 43rd percentile for the three-year period and the 48th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe.

Still, it is surprising how often we forget these basic lessons. Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s had many people hoping they could become millionaires overnight. But the market decline that started in the spring of 2000 taught everyone how misguided those hopes had been. Now, less than six years after the market taught a harsh lesson in the follies of speculative investing, we are seeing a number of trends that suggest many investors, including professionals, are hoping for overnight miracles again. We see a steady stream of market "gurus" on television news shows, promising to teach amateur investors the strategies that will allow them to get rich quick. Hedge funds - which by their nature move in and out of investments rapidly - have soared in popularity in recent years. We are reminded every day that we live in a "what have you done for me lately?" world, but this mindset should not influence how we invest and manage our money. In fact, investors often fall short of their goals because they traded in and out of investments too frequently and at inopportune times. Throughout our more than 80-year history, MFS' money management process has focused on long-term investment opportunities. We firmly believe that the best way to realize long-term financial goals - be it a college education, a comfortable retirement, or a secure family legacy - is to follow a three- pronged approach that focuses on longer time horizons. Allocate holdings across the major asset classes - including stocks, bonds, and cash. Diversify within each class to take advantage of different market segments and investing styles. And rebalance assets regularly to maintain a desired asset allocation.* This long-term approach requires diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) February 15, 2006 * Asset allocation, diversification, and rebalancing do not guarantee a profit or protect against a loss. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. MANAGEMENT REVIEWS CAPITAL APPRECIATION SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 0.92%, while Service Class shares provided a total return of 0.63%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 5.26% for the series' benchmark, the Russell 1000 Growth Index. DETRACTORS FROM PERFORMANCE The technology sector was the largest detractor from relative performance over the period. Poor stock selection was the primary reason for relative underperformance within the sector. Our holdings in printer products manufacturer Lexmark International*, security software firm Symantec, and networking and communications manufacturer Cisco Systems held back results as these stocks underperformed the index over the reporting period. Underweighting computer manufacturer Apple Computer* also weighed on relative results. No individual stocks within the leisure sector were among the portfolio's top detractors. Security selection in the industrial goods and services and retailing sectors also dampened results. In industrial goods and services, manufacturing conglomerate Tyco International (not an index constituent) weakened performance. In retailing, online retailer and services provider IAC/ InterActiveCorp* held back results. Elsewhere, holdings in motorcycle manufacturer Harley-Davidson* and biotech firm ImClone Systems* hampered results. Our virtual avoidance of drug maker Pfizer*, which outperformed during the period, also held back performance. The portfolio's cash position was also a detractor from relative performance. The portfolio holds cash to buy new holdings and to provide liquidity. In a period when equity markets rose, as measured by the portfolio's benchmark, holding cash hurt performance versus the benchmark, which has no cash position. CONTRIBUTORS TO PERFORMANCE Stock selection and an underweighted position in the financial services sector, which underperformed the index, added to relative results. No individual stocks within the sector were among the portfolio's top contributors. Stock selection in the basic materials sector helped relative results. Within the sector, Brazilian iron ore miner Companhia Vale do Rio Doce* (not an index constituent) contributed to performance. Overweighting the energy sector and strong stock selection in the health care sector also boosted relative performance. In energy, oil and gas supplier Tenaris* (not an index constituent) aided results. In health care, our holdings in biotech firm Amgen, pharmaceutical and diagnostic company Roche Holding (not an index constituent), and hospital operators HCA* and Community Health Systems* proved favorable. Other individual stocks that contributed to relative performance included drug store chain CVS and microchip and electronics manufacturer Samsung Electronics (not an index constituent). Additionally, not owning International Business Machine (IBM) and underweighting industrial conglomerate General Electric enhanced relative results as both stocks performed poorly relative to the overall index over the period. * Security was not held in the portfolio at period-end. EMERGING GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 9.14%, while Service Class shares provided a total return of 8.90%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 5.17% for the series' benchmark, the Russell 3000 Growth Index. CONTRIBUTORS TO PERFORMANCE Over the period, the financial services, health care, and technology sectors boosted results. In each case, the primary driver was strong stock selection. In financial services, investment management firm Legg Mason and commodities exchange Chicago Mercantile Exchange Holdings were among the top contributors to relative performance. Despite its positive contribution to relative performance, no individual stocks within the health care sector were among the portfolio's top contributors. In technology, our holdings in Internet search engine Google, maker of flash memory storage products SanDisk, and South Korean microchip and electronics manufacturer Samsung Electronics (not an index constituent) proved beneficial to relative performance. Not holding weak-performing International Business Machines (IBM) also helped relative results. The portfolio's overweighted position in the utilities and communications sector bolstered results as the sector outperformed the overall index. Broadcast and communications operator American Tower and Latin American wireless communications company America Movil (not an index constituent) were among the portfolio's top relative contributors. Other individual contributors to performance included drilling rig operator GlobalSantaFe, which is not held in the index, and media image provider Getty Images. DETRACTORS FROM PERFORMANCE Stock selection and, to a lesser extent, an overweighted position in the leisure sector detracted from relative performance. Video games maker Electronic Arts was among the portfolio's top detractors over the period. Stock selection in the industrial goods and services and autos and housing sectors also held back results. No individual stocks in the industrial goods and services sector were among the top detractors. In autos and housing, sleep products manufacturer Tempur-Pedic International* dampened relative performance. While no individual stocks in the special products and services sector were among the portfolio's top detractors during the period, our overweighted position in this sector hampered performance as the sector underperformed the benchmark. Elsewhere, our holdings in network security software company Symantec* and software provider Mercury Interactive* hurt returns. In health care, dermatological treatment company Medicis Pharmaceutical*, biotech firms ImClone Systems and Genentech, and health care service provider UnitedHealth Group negatively affected relative performance. Not holding pharmaceutical company Pfizer also proved disappointing as the stock performed better than the overall index during the period. In retailing, discount store Family Dollar Stores* hindered relative results. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. * Security was not held in the portfolio at period-end. GLOBAL GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 10.03% while Service Class shares provided a total return of 9.65%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 11.16% for the series' benchmark, the MSCI All Country World Growth Index. The series' other benchmark, the MSCI World Growth Index, provided a return of 9.74%. DETRACTORS FROM PERFORMANCE Although our relative underweighting in the technology sector aided results, this was more than offset by security selection in this sector. Our positions in network security software company Symantec, which is not a benchmark constituent, and computer company Dell* hurt relative returns. Not owning strong-performing index constituents Apple Computer and Google also hindered results as both stocks more than doubled over the period. The financial services and energy sectors also held back results, although no individual holdings in either sector were among the portfolio's top relative detractors. In other sectors, pay-television operator Premiere*, home improvement retailer Kingfisher*, apparel retailer NEXT, and biotech firm ImClone Systems*, which is not a benchmark constituent, dampened performance. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. CONTRIBUTORS TO PERFORMANCE Stock selection in the consumer staples, industrial goods and services, and retailing sectors contributed to the portfolio's relative performance over the period. Our positions in strong-performing Brazilian brewer Companhia de Bebidas das Americas* and convenience store operator 7-Eleven*, which is not a benchmark constituent, boosted relative results in the consumer staples and the retailing sectors, respectively. No individual holdings in the industrial goods and services sector were among the portfolio's top contributors. Elsewhere, our holdings in petrochemical company Reliance Industries, metal miner Companhia Vale do Rio Doce, and global cement producer Cemex* aided portfolio results. Avoiding benchmark constituent International Business Machines (IBM) also helped as shares declined over the year. Other stocks that contributed to performance included consumer finance company AEON Credit Service, generic drug manufacturer Teva Pharmaceutical Industries, oil and gas company Talisman Energy, and electronics manufacturer Samsung Electronics. * Security was not held in the portfolio at period-end. MASSACHUSETTS INVESTORS TRUST SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 7.70%, while Service Class shares provided a total return of 7.42%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.91% for the series' benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index). CONTRIBUTORS TO PERFORMANCE During the period, the energy, financial services, and health care sectors contributed to relative performance. Security selection was the primary driver of positive relative returns. In energy, oil field services provider Halliburton, exploration and production company EOG Resources, offshore drilling companies Noble Corp. and Transocean, and Canadian oil and gas company EnCana, which is not an index constituent, contributed to relative performance. In financial services, investment management firm Legg Mason (not an index constituent) aided relative results. In health care, our holdings in biotech firm Gilead Sciences proved beneficial. Other individual contributors over the period included personal computer maker Apple Computer and agrichemical products manufacturer Monsanto. Our avoidance of computer products and services provider International Business Machines (IBM), was also favorable to relative performance, as the stock declined early in the period. DETRACTORS FROM PERFORMANCE The utilities and communications sector detracted from relative performance over the period. U.K.-based wireless phone services provider Vodafone Group (not an index constituent) held back relative results. Although the transportation and special products and services sectors also hurt results, no individual stocks within these sectors were among the top detractors of the portfolio. Elsewhere, pharmaceutical company Abbott Laboratories and orthopedic products designer and marketer Zimmer Holdings hurt the portfolio's relative performance. Also, not holding oil and gas company ExxonMobil hampered results as the stock performed better than the benchmark. Stocks in other sectors that detracted from results included manufacturing conglomerate Tyco International, direct-sale computer vendor Dell, home improvement products maker Masco, video games maker Electronic Arts, cosmetics and beauty supply company Avon*, and enterprise software giant Oracle. During the reporting period, the portfolio's currency exposure was a detractor from the portfolio's relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. * Security was not held in the portfolio at period-end. MID CAP GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 3.10%, while Service Class shares provided a total return of 2.78%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 12.10% for the series' benchmark, the Russell Midcap Growth Index. DETRACTORS FROM PERFORMANCE The retailing, technology, and leisure sectors were the largest detractors from relative performance over the period. In all three sectors, stock selection dampened investment results. Several individual securities in the technology sector significantly hurt results including network security software company Symantec, which is not a benchmark constituent, business software company Mercury Interactive*, and semiconductor manufacturers PMC-Sierra and Xilinx. In the leisure sector, radio broadcasting firm Citadel Broadcasting, media company Gemstar-TV Guide*, and cruise line operator Royal Caribbean Cruises*, which is not a benchmark constituent, held back results relative to the benchmark. No individual stocks within the retailing sector were among the portfolio's top detractors. Other stocks that hurt performance included for-profit education company Apollo Group, which is not an index constituent, dermatological treatment company Medicis Pharmaceutical, and biotech firm ImClone Systems. CONTRIBUTORS TO PERFORMANCE Stock selection in the financial services sector boosted relative performance as our holdings in investment management firm Legg Mason significantly outperformed the benchmark over the period. Results were aided by our overweighted position in the strong-performing utilities and communications sector. Within this sector, broadcast and communication tower management firm American Tower was the top contributor. Elsewhere, in technology, networking chip maker Marvell Technology Group, which is not a benchmark constituent, and flash memory storage products maker SanDisk bolstered results. Our positioning in multimedia and publishing software company Adobe Systems also contributed as we added the stock to the portfolio prior to a run-up in share price. In health care, our holdings in biotech firm Gilead Sciences and medical device company Thoratec, neither of which are benchmark constituents, and non- urban hospital operator Community Health Systems* were among the portfolio's top contributors. Other individual holdings that benefited portfolio performance included drilling rig operator GlobalSantaFe, which is not a benchmark constituent, and multimedia image provider Getty Images. * Security was not held in the portfolio at period-end. RESEARCH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 7.94% while Service Class shares provided a total return of 7.71%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.91% for the series' benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index). CONTRIBUTORS TO PERFORMANCE Stock selection in the financial services sector boosted relative performance as our holdings in investment management firm Legg Mason, which is not a benchmark constituent, significantly outperformed the benchmark over the period. Other stocks in this sector that positively impacted results included investment manager Franklin Resources and investment banking firm Goldman Sachs Group. Security selection in the energy sector also contributed to performance. Our holdings in drilling rig operator GlobalSantaFe, which is not a benchmark constituent, was the top contributing stock within this sector. Other energy stocks that benefited relative results included offshore drilling company Noble Corp., oil field services provider Halliburton*, and French integrated oil company TOTAL, which is not an index constituent. Although the portfolio benefited from strong stock selection in the special products and services sector, no individual stocks within this sector were among the portfolio's top contributors. Stocks in other sectors that aided performance included flash memory storage products maker SanDisk, multimedia image provider Getty Images, and drug-maker Endo Pharmaceuticals Holdings, none of which are benchmark constituents. DETRACTORS FROM PERFORMANCE The technology sector was the largest relative detractor as stock selection within this sector held back results. Our holdings in network security software company Symantec* and computer company Dell proved disappointing as shares of both stocks declined over the period. Additionally, not owning strong-performing benchmark constituent Apple Computer was a drag on relative returns as the stock more than doubled over the year. The autos and housing and basic materials sectors also hurt results. In autos and housing, our positions in home improvement products maker Masco and motorcycle manufacturer Harley-Davidson* hindered results, while in basic materials, newsprint maker Bowater, which is not an index constituent, was among the top detractors. Elsewhere, biotechnology firm ImClone, apparel retailer Gap, and hospital operator Tenet Healthcare* dampened performance. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. * Security was not held in the portfolio at period-end. TOTAL RETURN SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 3.02%, while Service Class shares provided a total return of 2.81%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.91% for the series' benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index). The series' other benchmark, the Lehman Brothers U.S. Aggregate Bond Index, provided a return of 2.43%. DETRACTORS FROM PERFORMANCE Within the equity portion of the series, security selection in the utilities and communications sector detracted from relative performance. Overweighted positions in independent power producer Calpine* and telecom services provider Verizon Communications held back returns as both stocks lagged the S&P 500 Stock Index. Security selection within the basic materials sector also weighed on results. During the period, the portfolio's holdings in newsprint maker Bowater (not an S&P 500 Stock Index constituent) hurt relative performance. A combination of an overweighted position and stock selection within the leisure sector held back investment results. Overweighting poor-performing global entertainment conglomerate Viacom negatively impacted the portfolio's relative performance. Elsewhere, holdings in health care firm Tenet Healthcare hurt results as the stock underperformed the S&P 500 Stock Index. In technology, positions in network security firm Symantec and telecom equipment company Nortel Networks (not an S&P 500 Stock Index constituent), and the avoidance of strong- performing Apple Computer, detracted from relative performance. Overweighting home improvement firm Masco (in the autos and housing sector) and retailer Gap also held back returns. During the reporting period, currency exposure within the equity portion of the series was a detractor from relative performance. All of MFS' equity investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. Within the fixed income portion of the series, overweighting "BBB"-rated(1) securities held back performance relative to the Lehman Brothers U.S. Aggregate Bond Index. During the period, spreads on "BBB"-rated debt widened, causing bonds within this quality sector to lose value. Specific sectors that detracted from performance included finance and agency-related debt. In the finance sector, bonds of Ford Motor Credit and General Motors Acceptance Corp hurt returns. CONTRIBUTORS TO PERFORMANCE Within the equity portion of the series, a combination of an overweighted position and positive security selection within the strong-performing energy sector boosted performance relative to the S&P 500 Stock Index. Overweighting a number of energy firms contributed to the portfolio's relative results, including oil and gas producer Devon Energy, energy exploration and production company EOG Resources, and offshore drilling company Noble Corp. Positions in drilling rig operator GlobalSantaFe and oil and gas service company Cooper Cameron, neither of which are S&P 500 Stock Index constituents, also helped. A combination of stock selection and, to a lesser extent, the portfolio's overweighting in the financial services sector contributed to relative results over the period. Although financial services was a top contributing sector on a relative basis, no individual securities within the sector were among the portfolio's top contributors. An overweighted position and positive security selection within the special products and services sector also aided results. Avoiding poor-performing Internet auctioneer eBay benefited returns as the stock underperformed the S&P 500 Stock Index over the period. Elsewhere, underweighting information technology firm International Business Machines (IBM) and computer manufacturer Dell* in the technology sector added to relative performance. In health care, underweighting weak-performing pharmaceutical giant Pfizer* also boosted results. In the industrial goods and services sector, overweighting aerospace and defense firm Lockheed Martin proved beneficial to performance as the stock outperformed the S&P 500 Stock Index. Within the fixed income portion of the series, the stance on duration(2) aided performance relative to the Lehman Brothers U.S. Aggregate Bond Index. During the period, the portfolio maintained a shorter duration than the index. Holdings of Treasury securities bolstered performance over the period as did the portfolio's positioning in mortgage-backed and asset-backed securities. * Security was not held in the portfolio at period-end. UTILITIES SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 17.23%, while Service Class shares provided a total return of 16.97%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 16.84% for the series' benchmark, the Standard & Poor's 500 Utilities Index. CONTRIBUTORS TO PERFORMANCE Strong stock selection in the electric power industry contributed to the portfolio's relative returns for the period. Within this industry, wholesale power generator NRG Energy and Brazilian electricity provider CPFL Energia, neither of which are benchmark constituents, were among the portfolio's top contributors. Additionally, not holding electric power companies Southern Company, independent power producer Calpine, and Progress Energy (all benchmark constituents which lagged overall benchmark returns) aided relative performance. Our positions in the oil service industry, which is not represented in the index, bolstered results. Oil field services provider Halliburton contributed positively to the portfolio's relative performance over the period. Stock selection in the natural gas distribution industry also boosted relative performance. Our position in Questar, which is not a benchmark constituent, helped performance as the stock value appreciated significantly over the period. Not owning weak-performing benchmark constituent KeySpan also proved favorable. Elsewhere, our holdings in Mexican wireless communications company America Movil and Brazilian oil and gas exploration and production company Petroleo Brasileiro, neither of which are benchmark constituents, also had a positive impact on the portfolio's relative results. DETRACTORS FROM PERFORMANCE Holdings in the telephone services industry hurt relative results. Several stocks within this industry, which is not represented in the index, were among the portfolio's greatest individual detractors. These included wireless services companies Sprint Nextel, Deutsche Telekom*, and Telefonica*. Our positions in the broadcast and cable television industry, which is not represented in the index, also hindered relative performance. Among the portfolio's top detractors were media and entertainment company News Corp, cable services provider Comcast, and media giant Viacom. Although the electric power industry contributed to relative performance, our underweighted positions in several strong-performing benchmark constituents detracted from results. These included TXU, Public Service Enterprise Group*, and FirstEnergy. Our holdings in wireless communications provider Vodafone Group, which is not a benchmark constituent, also held back relative returns. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity, and as such, it is common for our portfolios to have different currency exposure than the benchmark. *Security was not held in the portfolio at period-end.

NOTES TO PERFORMANCE SUMMARY Initial Class shares have no sales charge. Service Class shares have no sales charge and carry a 0.25% annual Rule 12b-1 fee. Service Class share performance includes the performance of Initial Class shares for periods prior to the inception of Service Class shares (blended performance). These blended performance figures have not been adjusted to take into account differences in the class-specific operating expenses (such as Rule 12b-1 fees). Because operating expenses of Service Class shares are generally higher than those of Initial Class shares, the blended Service Class shares performance shown is higher than it would have been had Service Class shares been offered for the entire period. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these the results would have been less favorable. See the prospectus for details. All results are historical and assume the reinvestment of any dividends and capital gains distributions. The returns for the series shown do not reflect the deduction of expenses associated with variable products, such as mortality and expense risk charges, separate account charges, and sales charges imposed by insurance company separate accounts. Such expenses would reduce the overall returns shown. From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

KEY RISK CONSIDERATIONS CAPITAL APPRECIATION SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. EMERGING GROWTH SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. Changes in currency exchange rates may affect the portfolio's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. Growth stocks may perform differently from the general stock market and can be more volatile than other types of stocks. GLOBAL GROWTH SERIES Stock markets are volatile and can decline due to adverse issuer, political regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. Changes in currency exchange rates may affect the portfolio's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. Because MFS may invest a relatively large percentage of the portfolio's assets in issuers located in a single country or a small number of countries, the portfolio's performance could be closely tied to the market, economic, political or regulatory conditions and developments in those countries and could be more volatile than the performance of more geographically diversified portfolios. Growth stocks may perform differently from the general stock market and can be more volatile than other types of stocks.

The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Derivatives involve risks different from, and greater than, those of the underlying indicator's in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. UTILITIES SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. Because the portfolio's investments are focused in a particular industry or sector, the portfolio's performance may depend more heavily on the performance of that industry or sector and therefore may be more volatile than the market as a whole. The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Derivatives involve risks different from, and greater than, those of the underlying indicator's in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. Lower quality debt securities involve substantially greater risk of default and their value can decline significantly over time. When you sell units, they may be worth more or less than the amount you paid for them. Please see the prospectus for further information regarding these and other risks considerations. EXPENSE TABLES SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JULY 1, 2005 THROUGH DECEMBER 31, 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, July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The first line for each share class in the following tables 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 following tables 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 tables 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 tables 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.

(i) For the period from the class' inception, August 24, 2001 (Service Class) through the stated period end. (v) The series' total return calculation includes a net increase from gains realized on the disposal of investments in violation of the series' investment restrictions. The gains resulted in an increase in net asset value of $0.00278 per share based on shares outstanding on the day the gains were realized. Excluding the offset of these gains from the series' ending net asset value per share, the total returns for the year ended December 31, 2004 would have been approximately 30.35% and 29.99% for the Initial Class shares and the Service Class shares, respectively. (k) 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. (b) 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 fund sales. The non-recurring accrual 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. (g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing of sales of series shares and the amount of per share realized and unrealized gains and losses at such time. See notes to financial statements. MFS/SUN LIFE SERIES TRUST NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION The Trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company consisting of twenty-eight separate series (the series) of shares: Bond Series, Capital Appreciation Series*, Capital Opportunities Series, Core Equity Series, Emerging Growth Series*, Emerging Markets Equity Series, Global Governments Series, Global Growth Series*, Global Total Return Series, Government Securities Series, High Yield Series, International Growth Series, International Value Series, Massachusetts Investors Growth Stock Series, Massachusetts Investors Trust Series*, Mid Cap Growth Series*, Mid Cap Value Series, Money Market Series, New Discovery Series, Research Series*, Research International Series, Strategic Growth Series, Strategic Income Series, Strategic Value Series, Technology Series, Total Return Series*, Utilities Series*, and Value Series. The shares of each series are sold only to variable accounts established by Sun Life Assurance Company of Canada (U.S.) and Sun Life Insurance and Annuity Company of New York to fund benefits under variable contracts issued by such companies. The series denoted with an asterisk above are included within these financial statements. (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. Certain series can invest in foreign securities, including securities of emerging market issuers. 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. The markets of emerging markets countries are generally more volatile than the markets of developed countries with more mature economies. All of the risks of investing in foreign securities previously described are heightened when investing in emerging markets countries. Investment Valuations - Equity securities, including restricted equity securities, are generally valued at the last sale or official closing price as reported by an independent pricing service on the market or exchange on which they are primarily traded. For securities for which there were no sales during the day, equity securities are generally valued at the last quoted bid price as reported by an independent pricing service on the market or exchange on which they are primarily traded. Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated bid price as reported by an independent pricing service. Values of debt instruments obtained from pricing services can utilize both dealer- supplied valuations and electronic data processing techniques which take into account 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. Short-term instruments with a maturity at issuance of 365 days or less are generally valued at amortized cost, which approximates market value. Forward foreign currency contracts are generally valued at the mean of bid and asked prices based on rates reported by an independent pricing service. Open-end investment companies are generally valued at their net asset value per share. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued on the basis of information from brokers and dealers. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars based upon exchange rates provided by an independent source. 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, in valuing securities that trade principally on foreign markets, events reasonably determined to be significant (such as certain movements 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 series' valuation time 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 prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Fair valuation of foreign equity securities may occur frequently based on an assessment that events which occur on a fairly regular basis (such as U.S. market movements) are significant. Repurchase Agreements - Each series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. Each 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. Each 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. Each 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. Inflation-Adjusted Debt Securities - Certain series invest in inflation- adjusted debt securities issued by the U.S. Treasury. Certain series may also invest in inflation-adjusted debt securities issued by U.S. Government agencies and instrumentalities other than the U.S. Treasury and by other entities such as U.S. and foreign corporations and foreign governments. The principal value of these debt securities is adjusted by references to changes in the Consumer Price Index or another general price or wage index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation. 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. Derivative Risk - Each series may invest in derivatives for hedging or non- hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When each series uses derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include forward foreign currency exchange contracts for the Utilities Series. Forward Foreign Currency Exchange Contracts - Each 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 the contract. Each series may enter into forward foreign currency exchange contracts for hedging purposes as well as for non- hedging purposes. For hedging purposes, each series may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. Each 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, each 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. 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 certain 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 certain series with indemnification against Borrower default. Each 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. 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. Certain dividends from foreign securities will be recorded as soon as each series is informed of the dividend if such information is obtained subsequent to 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. Each series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statements of Operations, or in unrealized gain/loss if the security is still held by the series. Fees Paid Indirectly - Certain series' custody fees are reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the year ended December 31, 2005, certain series' custodian fees were reduced under this arrangement as noted below. Each 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 year ended December 31, 2005, each series' custodian expenses were reduced under this agreement as noted below. These amounts are shown as a reduction of total expenses on the Statements of Operations.

Accordingly, no provision for federal income tax is required in the financial statements. Foreign taxes, if any, have been accrued by the series in the accompanying financial statements. Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statements and tax purposes will reverse at some time in the future. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income for financial statement and tax purposes. Book/tax differences primarily relate to amortization and accretion of debt securities, wash sale loss deferrals, foreign currency transactions, derivative transactions, net operating losses and capital loss carryforwards, which were assumed as a result of an acquisition. The tax character of distributions declared to shareholders is as follows: Capital Appreciation Massachusetts Series Emerging Growth Series Global Growth Series Investors Trust Series ------------------------ ------------------------ ------------------------- ----------------------- December 31, December 31, December 31, December 31, ------------------------ ------------------------ ------------------------- ----------------------- 2005 2004 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) .................. $4,352,922 $433,984 $ -- $ -- $764,349 $843,092 $10,690,035 $11,697,097 ========== ======== ======== ======= ======== ======== =========== =========== Mid Cap Growth Series Research Series Total Return Series Utilities Series ------------------------ ------------------------ ------------------------- ----------------------- December 31, December 31, December 31, December 31, ------------------------ ------------------------ ------------------------- ----------------------- 2005 2004 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) .................. $ -- $ -- $2,354,184 $4,201,673 $ 54,343,213 $48,429,855 $3,641,287 $6,205,650 Long-term capital gain .... -- -- -- -- 53,279,570 -- -- -- ----- ----- --------- --------- ----------- ---------- --------- --------- Total distributions ....... $ -- $ -- $2,354,184 $4,201,673 $107,622,783 $48,429,855 $3,641,287 $6,205,650 ======= ======= ========== ========== ============ =========== ========== ========== As of December 31, 2005, the federal tax cost and the tax basis components of distributable earnings were as follows: Capital Emerging Global Massachusetts Appreciation Growth Growth Investors Trust Series Series Series Series - -------------------------------------------------------------------------------------------------------------------------------- Cost of investments ..................................... $ 674,052,256 $ 341,304,142 $ 162,016,678 $1,014,196,532 -------------- -------------- -------------- -------------- Gross appreciation ...................................... $ 24,428,107 $ 62,093,534 $ 24,022,593 $ 158,372,558 Gross depreciation ......................................

Multiple Classes of Shares of Beneficial Interest - Each 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 - Each 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 based on a percentage of each series' average daily net assets as follows: Capital Appreciation Series: The management fee is 0.75% of the first $1 billion of average daily net assets, 0.675% of the next $500 million of average daily net assets and 0.65% of average daily net assets in excess of $1.5 billion. Emerging Growth Series: The management fee is 0.75% of the first $300 million of average daily net assets and 0.675% of average daily net assets in excess of $300 million. Global Growth Series: The management fee is 0.90% of the first $1 billion of average daily net assets, 0.75% of the next $1 billion of average daily net assets and 0.65% of average daily net assets in excess of $2 billion. Massachusetts Investors Trust Series: The management fee is 0.55% of average daily net assets. Mid Cap Growth Series: Prior to September 1, 2005, the management fee was 0.75% of the series' average daily net assets. Effective September 1, 2005, the management fee is 0.75% of the first $1 billion of average daily net assets and 0.70% of average daily net assets in excess of $1 billion. The investment adviser has contractually agreed to reduce its fee to 0.70% in excess of $500 million for the period September 1, 2005 through April 30, 2007. This reduction of the management fee may be rescinded by MFS only with the approval of the series' Board of Trustees. Research Series: The management fee is 0.75% of the first $300 million of average daily net assets and 0.675% of average daily net assets in excess of $300 million. Total Return Series: The management fee is 0.75% of the first $300 million of average daily net assets, 0.675% of the next $700 million of average daily net assets and 0.60% of average daily net assets in excess of $1 billion. Utilities Series: The management fee is 0.75% of the first $300 million of average daily net assets and 0.675% of average daily net assets in excess of $300 million. The investment adviser has agreed to pay a portion of certain series' operating expenses, exclusive of certain other fees and expenses, such that the operating expenses of these series do not exceed the expense limitations indicated below, based on the average daily net assets of such series. The management fees and expense limitations incurred for the year ended December 31, 2005 were equivalent to an annual effective rate of each series' average daily net assets as follows: Effective Initial Class Service Class Management Expense Expense Fees Limitations Limitations - -------------------------------------------------------------------------------- Capital Appreciation Series ......... 0.75% 1.00% 1.25% Emerging Growth Series .............. 0.73% N/A N/A Global Growth Series ................ 0.90% N/A N/A Massachusetts Investors Trust Series 0.55% 1.00% 1.25% Mid Cap Growth Series ............... 0.75% N/A N/A Research Series ..................... 0.73% N/A N/A Total Return Series ................. 0.65% 1.00% 1.25% Utilities Series .................... 0.73% N/A N/A 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 each 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 in connection with the sale and distribution of the series' Service Class shares and the sale and distribution of the variable annuity or variable life insurance contracts investing indirectly in Service Class shares. MFD may subsequently pay all, or a portion, of the distribution fees to financial intermediaries. Administrator - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to each series and certain other MFS Funds (the 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 year ended December 31, 2005 was equivalent to an annual effective rate of each series' average daily net assets as follows: Percent of Average Net Assets - ------------------------------------------------------------------------------- Capital Appreciation Series ...................................... 0.0178% Emerging Growth Series ........................................... 0.0175% Global Growth Series ............................................. 0.0175% Massachusetts Investors Trust Series ............................. 0.0176% Mid Cap Growth Series ............................................ 0.0175% Research Series .................................................. 0.0176% Total Return Series .............................................. 0.0174% Utilities Series ................................................. 0.0178% Trustees' and Officers' Compensation - Each series pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to the Board chairperson. Each 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, MFD, and MFS Service Center, Inc. (MFSC). Other - 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and the Shareholders of MFS/Sun Life Series Trust: We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of MFS/Sun Life Series Trust (the "Trust"), comprising Capital Appreciation Series, Emerging Growth Series, Global Growth Series, Massachusetts Investors Trust Series, Mid Cap Growth Series, Research Series, Total Return Series and Utilities Series as of December 31, 2005, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements and financial highlights present fairly, in all material respects, the financial positions of Capital Appreciation Series, Emerging Growth Series, Global Growth Series, Massachusetts Investors Trust Series, Mid Cap Growth Series, Research Series, Total Return Series and Utilities Series as of December 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

All Trustees currently serve as Trustees of the Series and have served in that capacity since originally elected or appointed. All of the Trustees are also Managers of the Compass Variable Accounts. The executive officers of the MFS Sun Life Series Trust hold similar offices for the Compass Variable Accounts and other funds in the MFS fund complex. Each Trustee serves as a Trustee or Manager of 34 Accounts/Series. The Statement of Additional Information contains further information about the Trustees and is available without charge upon request by calling 1-800-752-7215. BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENTS 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, annually approve the continuation of the Trust's investment advisory agreements with Massachusetts Financial Services Company (MFS) on behalf of the Series. The Trustees consider matters bearing on the Series and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July 2005 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreements for the Series. The independent Trustees were assisted in their evaluation of the investment advisory agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS management during various contract review meetings. The independent Trustees were also assisted in this process by the Series' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations, 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 agreements were considered separately for each Series, although the Trustees also took into account the common interests of all Series 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 agreements and other arrangements with the Trust. 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 each Series for various time periods ended December 31, 2004, compared to the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("peer funds"), (ii) information provided by Lipper Inc. on each Series' advisory fees and other expenses compared to 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 its other clients, including 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 a 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, (vi) MFS' views regarding the outlook for the mutual fund industry and its strategic business plans, (vii) descriptions of various functions performed by MFS for the Trust, 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. The comparative performance, 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 continuation of the investment advisory agreements was based on 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 for each Series, while individual Trustees may have given different weight to various factors and evaluated the information presented as a whole differently than another Trustee. The Trustees recognized that the fee arrangements for the Series reflect years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees compared each Series' total return investment performance to the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of each Series' Initial Class shares in comparison to the performance of funds in its Lipper performance universe over the one-, three- and five-year periods. The Trustees did not rely on performance results for more recent periods, including those shown elsewhere in this report. In the course of their deliberations, the Trustees took into account information provided by MFS during contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year. For Series whose performance lagged their peer groups, they discussed MFS' efforts to improve such Series' performance. After reviewing this information, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreements, that they were satisfied with MFS' responses and efforts relating to investment performance. In assessing the reasonableness of each Series' advisory fee, the Trustees considered, among other information, each Series' advisory fee and the total expense ratio of the Series' Initial Class shares as a percentage of average net assets, compared to the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered the generally broader scope of services provided by MFS to the Trust than those provided to institutional accounts. The Trustees also considered 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 related expenses due to the more extensive regulatory regime to which the Series are subject, compared to institutional accounts. The Trustees also considered whether a Series is likely to benefit from any economies of scale due to future asset growth. In this regard, the Trustees reviewed the adequacy of breakpoints, and considered if breakpoints should be implemented for any Series that did not have them. The Trustees also considered information prepared by MFS relating to its costs and profits with respect to the Series and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the Series and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described below, the Trustees concluded 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. 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 the financial resources of MFS and its affiliation with Sun Life Financial Inc. The Trustees further considered any advantages and possible disadvantages of having an adviser which also serves other investment companies as well as institutional 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 agreements, including the 12b-1 fees the Series pay 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 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 Series were satisfactory. The Trustees also considered the benefits to MFS from the use of the Series' portfolio brokerage commissions to pay for research and other similar services (including MFS' current 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 Trust, and determined that any such benefits derived by MFS were reasonable and fair. Based on their evaluation of factors that they deemed to be material, including those factors described above, and the individual Series factors noted below, the Board of Trustees, including a majority of the independent Trustees, concluded that the investment advisory agreements should be continued for an additional one-year period, commencing September 1, 2005. CAPITAL APPRECIATION SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 19th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 59th percentile for the three-year period and the 62nd percentile for the five- year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS and the Series' improving performance, the Board of Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted that MFS currently observes a voluntary expense limitation for the Series, which may not be changed without the Trustees' approval. The Trustees noted from the Lipper data that the Series' effective advisory fee rate and total expense ratio were each approximately at the median of such fees and expenses of funds in the Lipper expense group. The Trustees concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. EMERGING GROWTH SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 25th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 75th percentile for the three-year period and the 89th percentile for the five- year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS and the Series' improving performance, the Board of Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted that MFS currently observes a voluntary expense limitation for the Series, which may not be changed without the Trustees' approval. The Trustees noted from the Lipper data that the Series' effective advisory fee rate and total expense ratio were each approximately at the median of such fees and expenses of funds in the Lipper expense group. The Trustees further concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. GLOBAL GROWTH SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 56th percentile relative to the other funds in the peer universe for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 58th percentile for the three- year period and the 63rd percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. The Trustees noted the improved relative performance to the index since October 2003 when the current portfolio management team was put fully in place. Based on the nature and quality of services provided by MFS, and MFS' efforts to improve performance, the Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate and total expense ratio were each higher than the median of such fees and expenses of funds in the Lipper expense group. The Trustees also concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. MASSACHUSETTS INVESTORS TRUST SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 11th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 37th percentile for the three-year period and the 32nd percentile for the five- year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted that MFS currently observes a voluntary expense limitation for the Series, which may not be changed without the Trustees' approval. The Trustees noted from the Lipper data that the Series' effective advisory fee rate was lower than, and total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. They further noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints, but that the overall advisory fee adequately reflected economies of scale. Accordingly, the Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. MID CAP GROWTH SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 50th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 95th percentile for the three-year period ended December 31, 2004, relative to the Lipper performance universe. (The Series had been in existence for less than five years.) Based on the nature and quality of services provided by MFS and the Series' improving performance, the Board of Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate and total expense ratio were each lower than the median of such fees and expenses of funds in the Lipper expense group. They also noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.05% on net assets over $1 billion, which took effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided.

In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was at, and the total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. The Trustees further concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided.

Still, it is surprising how often we forget these basic lessons. Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s had many people hoping they could become millionaires overnight. But the market decline that started in the spring of 2000 taught everyone how misguided those hopes had been. Now, less than six years after the market taught a harsh lesson in the follies of speculative investing, we are seeing a number of trends that suggest many investors, including professionals, are hoping for overnight miracles again. We see a steady stream of market "gurus" on television news shows, promising to teach amateur investors the strategies that will allow them to get rich quick. Hedge funds - which by their nature move in and out of investments rapidly - have soared in popularity in recent years. We are reminded every day that we live in a "what have you done for me lately?" world, but this mindset should not influence how we invest and manage our money. In fact, investors often fall short of their goals because they traded in and out of investments too frequently and at inopportune times. Throughout our more than 80-year history, MFS' money management process has focused on long-term investment opportunities. We firmly believe that the best way to realize long-term financial goals - be it a college education, a comfortable retirement, or a secure family legacy - is to follow a three- pronged approach that focuses on longer time horizons. Allocate holdings across the major asset classes - including stocks, bonds, and cash. Diversify within each class to take advantage of different market segments and investing styles. And rebalance assets regularly to maintain a desired asset allocation.* This long-term approach requires diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) February 15, 2006 * Asset allocation, diversification, and rebalancing do not guarantee a profit or protect against a loss. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. MANAGEMENT REVIEWS CAPITAL OPPORTUNITIES SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 1.64%, while Service Class shares provided a total return of 1.31%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.91% for the series' benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index). DETRACTORS FROM PERFORMANCE Relative to the portfolio's benchmark, utilities and communications, technology, and leisure were the portfolio's weakest-contributing sectors over the period. In the utilities and communications sector, stock selection detracted from relative returns. The portfolio's overweighted positions in independent power producer Calpine* and telecom services provider Verizon* were among the portfolio's top detractors for the period. In the technology sector, stock selection was the principal detractor as well. Holdings in network security software company Symantec and global telecom equipment maker Nortel Networks, which is not a constituent of the benchmark, held back relative returns. Stock selection and an overweighted position in the leisure sector also dampened investment results. Holdings in advertising and marketing services company Interpublic Group* and media giant Viacom detracted from the portfolio's relative returns. Stocks in other sectors that had a negative impact on performance included overweighted positions in poor-performing health services provider Tenet Healthcare and manufacturing conglomerate Tyco International. The portfolio's holdings in newsprint maker Bowater*, which is not a benchmark constituent, and not holding strong-performing Apple Computer also hurt results. During the reporting period, the portfolio's currency exposure detracted from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. CONTRIBUTORS TO PERFORMANCE Health care, retailing, and financial services were the portfolio's top contributing sectors over the period. Stock selection and an overweighted position in the health care sector boosted relative results. Holdings in biotech firm Gilead Sciences aided returns as the stock delivered strong performance. Not holding poor-performing pharmaceutical company Pfizer, a constituent of the benchmark, also helped. Although retailing was a top contributing sector overall, no individual stocks within the sector were among the portfolio's top contributors. In financial services, our avoidance of mortgage financier Fannie Mae, whose stock declined over the period, contributed to relative results. Several stocks in the energy sector also helped performance. Overweighted positions in drilling rig operator GlobalSantaFe and oil and gas equipment manufacturer Cooper Cameron* (neither of which are benchmark constituents), oil and gas producer Devon Energy, and offshore drilling company Noble Corp. were among the portfolio's top contributors. Holdings in strong-performing software developer Compuware*, diversified technology company Corning*, and cell phone manufacturer Nokia, which is not a benchmark constituent, also aided returns. * Security was not held in the portfolio at period-end. CORE EQUITY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 6.56%, while Service Class shares provided a total return of 6.39%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.91% for the series' benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index). CONTRIBUTORS TO PERFORMANCE Over the reporting period, the health care, consumer staples, basic materials, and utilities and communications sectors contributed to relative performance. In each case, strong stock selection was the primary driver. In health care, hospital operator HCA* and medical device maker Cyberonics* (not an index constituent) boosted relative results. Not holding poor-performing pharmaceutical giant Pfizer also proved favorable. Despite positive contribution to relative return from the consumer staples sector, no individual stocks within the sector were among the portfolio's top contributors. In basic materials, agrichemical products company Monsanto and Brazilian iron ore miner Companhia Vale do Rio Doce (not an index constituent) were among the portfolio's top contributors. Although strong stock selection also helped relative returns in the utilities and communications sector, no individual stocks within this sector were among the portfolio's top contributors. Despite being a relative detractor, the technology sector included some of the portfolio's top contributors. These included maker of flash memory storage products SanDisk and business intelligence software firm MicroStrategy, neither of which are benchmark constituents. Avoiding computer products and services provider International Business Machines (IBM) for most of the reporting period, during which the stock's price underperformed the index, also benefited the portfolio. Stocks in other sectors that contributed to relative results included investment management firm Legg Mason and French integrated oil company TOTAL*, neither of which are held in the index. DETRACTORS FROM PERFORMANCE Stock selection in the technology and leisure sectors held back relative performance over the period. In technology, procurement software and consulting services provider Ariba* (not an index constituent), direct-sale computer vendor Dell, and security software firm Symantec detracted from relative results. In leisure, advertising and marketing services conglomerate Interpublic Group* was among the portfolio's top detractors. Other individual detractors included home mortgage financier Freddie Mac*, regional bank North Fork Bancorp*, insurance firm American International Group (AIG)*, moving and relocation services company SIRVA* (not an index constituent), and discount retailer Family Dollar Stores*. Avoiding integrated oil company Chevron for most of the first three quarters of the reporting period, during which the price of the stock rose, and owning its shares during the fourth quarter when the stock underperformed the index, negatively affected relative performance. * Security was not held in the portfolio at period-end. INTERNATIONAL GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 14.91% while Service Class shares provided a total return of 14.62%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 13.64% for the series' benchmark, the MSCI EAFE Growth Index. CONTRIBUTORS TO PERFORMANCE Stock selection in the technology, utilities and communications, and energy sectors contributed to the portfolio's relative performance over the period. Within the technology sector, strong-performing South Korean microchip and electronics manufacturer Samsung Electronics was the greatest contributor to relative results. Performance was also bolstered by our holdings in UK radio chip designer CSR, which gained substantially over the period. A combination of security selection and an underweighted position in the utilities and communication sector boosted relative results. The portfolio benefited from not holding some of the poor-performers in this sector, including communications companies France Telecom (France) and Deutsche Telekom (Germany). In the energy sector, global seamless steel pipe manufacturer Tenaris* and Canadian oil and gas companies Talisman Energy and EnCana were among the portfolio's top relative contributors. Securities in other sectors that aided performance included Indian real estate finance firm Housing Development Finance, global cement producer Cemex, and Mexican television broadcaster Grupo Televisa. During the reporting period, the portfolio's currency exposure was a contributor to relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. DETRACTORS FROM PERFORMANCE Security selection in the basic materials, special products and services, and financial services sectors held back performance relative to the benchmark. In basic materials, not owning strong-performing index constituent Rio Tinto, a global mining company, hindered results. Some special products and services holdings were among the portfolio's top detractors over the period including Singaporean after-market services provider Accord Customer Care Solutions*. Additionally, holdings in Japanese technology investment firm Softbank* had a negative impact on relative results as we eliminated the stock from the portfolio prior to a significant run-up in share price. In the financial services sector, holdings in UK banking firm Royal Bank of Scotland Group*, and not owing benchmark constituent Mitsubishi UFJ Financial Group (Japan), hurt performance. Elsewhere, German pay-television operator Premiere*, UK-based apparel retailer NEXT, and Italian Internet services provider FastWeb dampened results. The portfolio's cash position was also a detractor from relative performance. The portfolio holds cash to buy new holdings and to provide liquidity. In a period when equity markets rose, as measured by the portfolio's benchmark, holding cash hurt performance versus the benchmark, which has no cash position. * Security was not held in the portfolio at period-end. MASSACHUSETTS INVESTORS GROWTH STOCK SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 4.37%, while Service Class shares provided a total return of 4.15%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 5.26% for the series' benchmark, the Russell 1000 Growth Index. DETRACTORS FROM PERFORMANCE The technology and industrial goods and services sectors were the largest detractors from relative performance. In both cases, stock selection was the main reason. Several technology holdings hurt relative returns including network security software company Symantec, which was the greatest individual detractor within the portfolio. Our holdings in semiconductor giant Intel hampered performance as we added the stock subsequent to a run-up in share price. Other technology positions that negatively impacted results included software provider Mercury Interactive* and computer company Dell. In industrial goods and services, holdings in manufacturing conglomerate Tyco International, which is not a benchmark constituent, dampened relative results. The portfolio's virtual avoidance of benchmark constituent Boeing* also detracted from performance as we missed out on a significant run-up in that stock's price. Stock selection and, to a lesser extent, an overweighted position in the weak- performing leisure sector hindered performance. No individual stocks within this sector were among the portfolio's top relative detractors. Although stock selection in health care significantly aided results for the period, several individual stocks detracted from performance. Specifically, underweighted positions in pharmaceutical giant Pfizer* and health insurer UnitedHealth Group, and our holdings in poor-performing biotech firm ImClone*, negatively affected results. During the reporting period, the portfolio's currency exposure was also a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. CONTRIBUTORS TO PERFORMANCE Security selection in the health care sector was the greatest contributor to relative performance. Within this sector, biotech firms Amgen and Gilead Sciences were among the portfolio's top contributing stocks as both significantly outperformed the benchmark over the period. Other health care holdings that aided results included generic drug manufacturer Teva Pharmaceutical Industries and pharmaceutical and diagnostic company Roche Holding, neither of which are benchmark constituents. Security selection in the basic materials sector, and a combination of security selection and an overall underweighted position in the financial services sector, also helped relative performance. No individual holdings in either sector were among the portfolio's top contributors. Several individual technology positions boosted results during the period including diversified technology company Corning and flash memory storage products maker SanDisk. Additionally, the portfolio's underweighted position in poor-performing computer giant International Business Machines (IBM)* benefited relative returns. In other sectors, drugstore chain CVS and Latin American wireless communications company America Movil, which is not a benchmark constituent, contributed to relative results. * Security was not held in the portfolio at period-end. MID CAP VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 7.63%, while Service Class shares provided a total return of 7.40%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 12.65% for the series' benchmark, the Russell Midcap Value Index. DETRACTORS FROM PERFORMANCE During the reporting period, weak stock selection in the basic materials sector hurt relative performance. Within this sector, holdings in newsprint maker Bowater and paper product manufacturer Smurfit-Stone Container were among the portfolio's top detractors. A combination of stock selection and an overweighted position in the lagging leisure sector held back relative results. Within this sector, holdings in radio stations operator Radio One* proved disappointing to investment results. Stock selection in the technology and utilities and communications sectors also hindered relative performance over the period. In technology, communication equipment manufacturer Avaya* and electronics manufacturing services company Solectron* detracted from relative results. In utilities and communications, leading independent power producer Calpine* (not an index constituent) negatively impacted relative performance. Stocks in other sectors that detracted from performance included hospital operator Tenet Healthcare, investment banking and management firm Friedman, Billings, Ramsey Group*, and sleep products maker Tempur-Pedic International (not an index constituent). Not holding independent oil refiner Valero Energy also dampened results. CONTRIBUTORS TO PERFORMANCE The portfolio's overweighted position in the strong-performing energy sector contributed to relative performance. Several individual stocks within the sector were among the portfolio's top contributors. These included drilling rig operator GlobalSantaFe, oil and gas producers Devon Energy and Range Resources*, and oil field services provider BJ Services, none of which are index constituents. Additionally, oil and gas exploration company Newfield Exploration, drilling rig operator Pride International, and energy exploration company EOG Resources* all benefited the portfolio. Stocks in other sectors that contributed to relative results included online brokerage services firm AmeriTrade Holding*, drug maker Endo Pharmaceuticals Holdings* (not an index constituent), and non-urban hospital operator Community Health Systems*. * Security was not held in the portfolio at period-end. NEW DISCOVERY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 5.21%, while Service Class shares provided a total return of 4.96%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.15% for the series' benchmark, the Russell 2000 Growth Index. CONTRIBUTORS TO PERFORMANCE Stock selection in the health care sector was the greatest contributor to relative performance. Within this sector, ventricular assist device maker Thoratec, medical devices manufacturer FoxHollow Technologies*, and pharmaceutical firm Adams Respiratory Therapeutics* were among the portfolio's top contributing stocks as they significantly outperformed the benchmark over the period. Other strong performers in the health care sector that aided results included brain monitoring company Aspect Medical Systems, diagnostic instruments firm Ventana Medical Systems, and medical devices maker Conceptus. Security selection in the technology sector also helped relative performance. Holdings in this area included flash memory storage products maker SanDisk, which is not a benchmark constituent, and multimedia software firm Nuance Communications. Although the portfolio benefited from strong stock selection in the industrial goods and services sector, no individual stocks within this sector were among the portfolio's top contributors. Individual stocks in other sectors that contributed to relative results included discount apparel and variety retailer Citi Trends and interactive entertainment software company THQ. DETRACTORS FROM PERFORMANCE An underweighted position and, to a lesser extent, stock selection in the strong-performing energy sector hindered relative performance. No individual holdings in this sector were among the portfolio's top detractors. The special products and services and the retailing sectors also detracted from relative performance. In both cases, stock selection held back results. Holdings in moving and relocation services company SIRVA* and hobby and craft retailer A.C. Moore Arts & Crafts were significant detractors in these sectors. Although stock selection in technology aided results for the period, several individual stocks within this sector detracted from performance. The portfolio's holdings in procurement software and consulting services provider Ariba*, integrated circuits maker Silicon Laboratories*, voice network products company AudioCodes*, which is not a benchmark constituent, and networking semiconductor firm PMC-Sierra negatively affected results. Stocks in other sectors that hurt relative results included market research and opinion polling firm Harris Interactive, frozen dessert maker CoolBrands International*, which is not a benchmark constituent, and sleep products manufacturer Tempur-Pedic International*. Not holding strong-performing medical equipment and supplies firm Intuitive Surgical also dampened relative returns. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. * Security was not held in the portfolio at period-end. RESEARCH INTERNATIONAL SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 16.56%, while Service Class shares provided a total return of 16.19%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 14.02% for the series' benchmark, the MSCI EAFE Index. CONTRIBUTORS TO PERFORMANCE Security selection in the energy, financial services, and health care sectors was the primary contributor to the portfolio's relative performance over the period. In energy, global seamless steel pipe manufacturer Tenaris*, Russian oil company LUKOIL, neither of which are benchmark constituents, and Norwegian oil and gas company Statoil boosted results as the stocks significantly outperformed the overall benchmark. Within the financial services sector, several strong-performing stocks that are not benchmark constituents benefited portfolio performance, including Brazilian banking firm Unibanco-Uniao de Bancos Brasileiros, and South Korean banking firms Kookmin Bank and Hana Financial Holdings*. Performance in this sector was also bolstered by Japanese real estate firm Leopalace21 and Japanese financial services company ORIX. Although security selection in the health care sector aided relative results over the period, no individual stocks within this sector were among the portfolio's greatest contributors. Securities in other sectors which aided performance included Korean microchip and electronics manufacturer Samsung Electronics and Brazilian iron ore miner Companhia Vale do Rio Doce. During the reporting period, the portfolio's currency exposure was a contributor to relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. DETRACTORS FROM PERFORMANCE Security selection in the special products and services sector held back performance relative to the benchmark. Within this sector, index constituent Softbank*, a Japanese technology investment firm, was among the portfolio's greatest detractors as the stock was sold prior to a strong run-up in share price. Stock selection in the retailing and basic materials sectors also hurt benchmark relative performance. Within retailing, UK-based home improvement store operator Kingfisher* was among the portfolio's greatest detractors. No individual holdings within basic materials were among the top detractors for the period. Several stocks in the utilities and communications sector were a drag on performance, including telecommunications companies Telefonica (Spain) and Deutsche Telekom* (Germany), and Italian Internet service provider FastWeb, which is not a benchmark constituent. Elsewhere, holdings in Japanese electronic devices manufacturer Seiko Epson*, Japanese video game console maker Nintendo, UK-based pharmaceutical company GlaxoSmithKline, and UK banking firm Royal Bank of Scotland Group hurt relative results. * Security was not held in the portfolio at period-end. STRATEGIC GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 1.40%, while Service Class shares provided a total return of 1.17%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 5.26% for the series' benchmark, the Russell 1000 Growth Index. DETRACTORS FROM PERFORMANCE Over the period, the energy and leisure sectors were the largest detractors from relative performance. No individual securities within these sectors were among the top detractors. Security selection within the technology sector was another major detractor during the period. Within technology, holdings in software firm Mercury Interactive* and computer maker Dell, and underweighting Apple Computer, held back relative results. Positions within other sectors that detracted from performance included underweighting pharmaceutical giant Pfizer* and overweighting industrial goods and services firm Tyco International*. CONTRIBUTORS TO PERFORMANCE Security selection within the health care sector contributed to relative performance. The portfolio's holdings in biotechnology companies Gilead Sciences and Amgen, generic drug maker Teva Pharmaceutical and hospital operator HCA Inc* added to results during the period. Other stocks that contributed to performance during the year included diversified technology company Corning, microchip and electronics manufacturer Samsung Electronics, publishing software firm Adobe Systems, and telecommunications equipment company QUALCOMM. * Security was not held in the portfolio at period-end. STRATEGIC VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of -0.39%, while Service Class shares provided a total return of -0.72%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 7.05% for the series' benchmark, the Russell 1000 Value Index. DETRACTORS FROM PERFORMANCE Relative to the portfolio's benchmark, utilities and communications, technology, and basic materials were the portfolio's largest detracting sectors over the period. In all three sectors, stock selection held back relative returns. In the utilities and communications sector, independent power producer Calpine*, which is not a benchmark constituent, and telecommunications services provider Verizon were among the portfolio's top detractors for the period. Stock selection within the technology sector also hurt relative results. Holdings in network security software company Symantec and global telecommunications equipment maker Nortel Networks, which is not a constituent of the benchmark, dampened relative results. In basic materials, the portfolio's holdings in newsprint maker Bowater and package manufacturer Owens-Illinois detracted from relative returns as both stocks underperformed the benchmark. Stocks in other sectors that hindered investment results included overweighted positions in poor-performing health services provider Tenet Healthcare, manufacturing conglomerate Tyco International, which is not a benchmark constituent, advertising and marketing services company Interpublic Group*, and media giant Viacom. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. CONTRIBUTORS TO PERFORMANCE Energy, financial services, and autos and housing were the portfolio's top contributing sectors over the period. Stock selection in the energy sector helped boost relative results with strong-performing drilling rig operator GlobalSantaFe, offshore drilling company Noble Corp, and oil field services provider BJ Services, none of which are benchmark constituents, among the portfolio's top contributors. Holdings in oil and gas producer Devon Energy and oil and gas equipment manufacturer Cooper Cameron also contributed to relative returns. In financial services, overweighting PNC Financial Services Group aided relative performance as the stock outperformed the benchmark over the period. Although autos and housing was a top-contributing sector, no individual stocks within the sector were among the portfolio's top contributors. Stocks in other sectors that aided relative results included overweighted positions in software developer Compuware, consumer electronics retailer Circuit City, and cell phone manufacturer Nokia, which is not a benchmark constituent. The portfolio's avoidance of poor-performing pharmaceutical giant Pfizer also helped relative results. * Security was not held in the portfolio at period-end. TECHNOLOGY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 6.19%, while Service Class shares provided a total return of 6.02%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 2.03% for the series' benchmark, the Goldman Sachs Technology Index. CONTRIBUTORS TO PERFORMANCE Security selection within the computer software industry contributed to relative performance. During the period, the portfolio's holdings in business software providers MicroStrategy and Opsware, publishing software company Adobe Systems, and network security firm Blue Coat Systems* added to returns. A combination of security selection and an underweighting in the electronics industry boosted relative performance. Holdings in flash memory storage products company SanDisk, networking chip maker Marvell Technology, and electronics manufacturer Samsung Electronics were among the portfolio's top contributors. In the Internet industry, strong-performing Google contributed to relative performance. An underweighted position in International Business Machines (IBM)* and holdings in strong-performing Apple Computer also helped relative results. DETRACTORS FROM PERFORMANCE Athough the business services and broadcast and cable television industries held back relative performance, no individual securities from either industry were among the portfolio's top detractors for the period. Within the leisure and toys industry, holdings in video game company Electronic Arts* hurt performance as the stock underperformed the benchmark over the period. Although the computer software industry contributed to relative performance, several stocks within this group dampened investment results. Holdings in testing software company Mercury Interactive* and network security software firm Symantec held back returns. Avoiding strong-performing computer maker Hewlett-Packard (an index constituent) detracted from relative returns. The portfolio's exposure to liquid crystal display (LCD) maker LG. Philips LCD also negatively impacted results. Elsewhere, holdings in telecommunications equipment company Motorola*, diversified technology company Corning, e-commerce software vendor Ariba*, network storage company Network Appliance*, and LCD flat panel display maker AU Optronics* held back relative returns. During the reporting period, the portfolio's currency exposure detracted from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. * Security was not held in the portfolio at period-end. VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2005, Initial Class shares of the series provided a total return of 6.60%, while Service Class shares provided a total return of 6.34%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 7.05% for the series' benchmark, the Russell 1000 Value Index. DETRACTORS FROM PERFORMANCE Security selection and, to a lesser extent, an overweighted position in the basic materials sector held back relative performance. Within the basic materials sector, overweighting manufacturing firm PPG Industries and paper and packaging company International Paper detracted from results as both stocks lagged the benchmark. Poor stock selection within the retailing and utilities and communications sectors also detracted from relative performance. Within these sectors, holdings in retailer Gap and mobile telecommunications firm Vodafone Group (not index constituents) dampened investment results. Elsewhere, within the financial services sector, holdings of mortgage giant Fannie Mae negatively impacted performance. Underweighting technology firm Hewlett-Packard* was a drag on results as the stock performed strongly during the period. Health care company Johnson & Johnson (not an index constituent) also held back relative returns. Overweighting leisure firm Viacom weighed on results. Not participating in the substantial run-up in the shares of energy firms Burlington Resources and Valero Energy was also detrimental to performance. During the reporting period, the portfolio's currency exposure was a detractor from relative performance. All of MFS' investment decisions are driven by the fundamentals of each individual opportunity and, as such, it is common for our portfolios to have different currency exposure than the benchmark. CONTRIBUTORS TO PERFORMANCE Security selection within the industrial goods and services sector added to relative performance over the period. Avoiding index constituent General Electric aided results as the stock lagged the return of the benchmark. A combination of stock selection and, to a lesser extent, underweighting the leisure sector boosted relative returns over the period. Although the leisure sector was a top contributing sector on a relative basis, no individual securities within the sector were among the top portfolio's contributors. Security selection drove positive results in the energy sector. Overweighting energy firms Unocal*, ConocoPhillips, EOG Resources, and Noble Corp (not an index constituent) benefited the portfolio. Elsewhere, underweighting weak-performing pharmaceutical giant Pfizer* bolstered performance. Our holdings in strong-performing investment bank Goldman Sachs and insurer MetLife were also among the portfolio's top contributors. Finally, in the transportation sector the portfolio's holdings in Burlington Northern Santa Fe and our holdings in consumer staples firm Altria Corp positively affected performance. * Security was not held in the portfolio at period-end.

PERFORMANCE SUMMARY -- continued INDEX DEFINITIONS STANDARD & POOR'S 500 STOCK INDEX - a capitalization-weighted index of 500 widely held equity securities, designed to measure broad U.S. equity performance. MSCI EAFE (EUROPE, AUSTRALASIA, FAR EAST) GROWTH INDEX - a market capitalization index that is designed to measure developed market growth equity performance, excluding the U.S. and Canada. RUSSELL 1000 GROWTH INDEX - constructed to provide a comprehensive barometer for growth securities in the large-cap segment of the U.S. equity universe. Companies in this index generally have higher price-to-book ratios and higher forecasted growth values. RUSSELL MIDCAP VALUE INDEX - constructed to provide a comprehensive barometer for the value securities in the mid-cap segment of the U.S. equity universe. Companies in this index generally have lower price-to-book ratios and lower forecasted growth values. RUSSELL 2000 GROWTH INDEX - constructed to provide a comprehensive barometer for growth securities in the small-cap segment of the U.S. equity universe. Companies in this index generally have higher price-to-book ratios and higher forecasted growth values.

GOLDMAN SACHS TECHNOLOGY INDEX - a modified capitalization-weighted index of selected technology stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Initial Class shares have no sales charge. Service Class shares have no sales charge and carry a 0.25% annual 12b-1 fee. Service Class share performance includes the performance of Initial Class shares for periods prior to the inception of Service Class shares (blended performance). These blended performance figures have not been adjusted to take into account differences in the class-specific operating expenses (such as Rule 12b-1 fees). Because operating expenses of Service Class shares are generally higher than those of Initial Class shares, the blended Service Class shares performance shown is higher than it would have been had Service Class shares been offered for the entire period. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these the results would have been less favorable. See the prospectus for details. All results are historical and assume the reinvestment of any dividends and capital gains distributions. The returns for the series shown do not reflect the deduction of expenses associated with variable products, such as mortality and expense risk charges, separate account charges, and sales charges imposed by insurance company separate accounts. Such expenses would reduce the overall returns shown. From time to time the series may receive proceeds from litigation settlements, without which performance would be lower. KEY RISK CONSIDERATIONS CAPITAL OPPORTUNITIES SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. CORE EQUITY SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions.

INTERNATIONAL GROWTH SERIES Stock markets are volatile and can decline due to adverse issuer, political, regulatory or economic conditions. The value of the portfolio's equity investments will fluctuate in response to many factors including company specific factors as well as general market conditions. Foreign investments can be more volatile than U.S. investments. Because MFS may invest a relatively large percentage of the portfolio's assets in issuers located in a single country or a small number of countries, the portfolio's performance could be closely tied to the market, economic, political or regulatory conditions and developments in those countries and could be more volatile than the performance of more geographically diversified portfolios. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. Growth stocks may perform differently from the general stock market and can be more volatile than other types of stocks.

EXPENSE TABLES SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, JULY 1, 2005 THROUGH DECEMBER 31, 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, July 1, 2005 through December 31, 2005. ACTUAL EXPENSES The first line for each share class in the following tables 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 following tables 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 tables 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 tables 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.

MFS/SUN LIFE SERIES TRUST FINANCIAL HIGHLIGHTS -- continued The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or life of a particular share class, if shorter). Certain information reflects financial results for a single series share. The total returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all distributions) held for the entire period. This information has been audited by the series' independent registered public accounting firm, whose report, together with the series' financial statements, are included in this report.

MFS/SUN LIFE SERIES TRUST NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION The Trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company consisting of twenty-eight separate series (the series) of shares: Bond Series, Capital Appreciation Series, Capital Opportunities Series*, Core Equity Series*, Emerging Growth Series, Emerging Market Equity Series, Global Governments Series, Global Growth Series, Global Total Return Series, Government Securities Series, High Yield Series, International Growth Series*, International Value Series, Massachusetts Investors Growth Stock Series*, Massachusetts Investors Trust Series, Mid Cap Growth Series, Mid Cap Value Series*, Money Market Series, New Discovery Series*, Research Series, Research International Series*, Strategic Growth Series*, Strategic Income Series, Strategic Value Series*, Technology Series*, Total Return Series, Utilities Series, and Value Series*. The shares of each series are sold only to variable accounts established by Sun Life Assurance Company of Canada (U.S.) and Sun Life Insurance and Annuity Company of New York to fund benefits under variable contracts issued by such companies. The series denoted with an asterisk above are included within these financial statements. (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. Certain series can invest in foreign securities, including securities of emerging market issuers. 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. The markets of emerging markets countries are generally more volatile than the markets of developed countries with more mature economies. All of the risks of investing in foreign securities previously described are heightened when investing in emerging markets countries. Investment Valuations - Equity securities, including restricted equity securities, are generally valued at the last sale or official closing price as reported by an independent pricing service on the market or exchange on which they are primarily traded. For securities for which there were no sales during the day, equity securities are generally valued at the last quoted bid price as reported by an independent pricing service on the market or exchange on which they are primarily traded. Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated bid price as reported by an independent pricing service. Values of debt instruments obtained from pricing services can utilize both dealer- supplied valuations and electronic data processing techniques which take into account 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. Short-term instruments with a maturity at issuance of 365 days or less are generally valued at amortized cost, which approximates market value. Open-end investment companies are generally valued at their net asset value per share. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued on the basis of information from brokers and dealers. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars based upon exchange rates provided by an independent source. 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, in valuing securities that trade principally on foreign markets, events reasonably determined to be significant (such as certain movements 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 series' valuation time 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 prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the series' valuation time. Fair valuation of foreign equity securities may occur frequently based on an assessment that events which occur on a fairly regular basis (such as U.S. market movements) are significant. Repurchase Agreements - Each series may enter into repurchase agreements with institutions that the series' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. Each 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. Each 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. Each 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 each 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 each series with indemnification against Borrower default. Each 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. Certain dividends from foreign securities will be recorded as soon as each series is informed of the dividend if such information is obtained subsequent to 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. Each series may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statements of Operations, or in unrealized gain/loss if the security is still held by the series. Fees Paid Indirectly - Certain series' custody fees are reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. During the year ended December 31, 2005, certain series' custodian fees were reduced under this arrangement as noted below. Certain series have 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 year ended December 31, 2005, certain series' custodian expenses were reduced under this agreement as noted below. These amounts are shown as a reduction of total expenses on the Statements of Operations.

Accordingly, no provision for federal income tax is required in the financial statements. Foreign taxes, if any, have been accrued by the series in the accompanying financial statements. Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statements and tax purposes will reverse at some time in the future. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income for financial statement and tax purposes. Book/tax differences primarily relate to net operating losses, real estate investment trusts, passive foreign investment companies, wash sale loss deferrals, and foreign currency transactions. The tax character of distributions declared to shareholders is as follows: Capital Opportunities International Growth Series Core Equity Series Series -------------------------- -------------------------- -------------------------- Year Ended December 31, Year Ended December 31, Year Ended December 31, -------------------------- -------------------------- -------------------------- 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) .............................. $2,157,384 $1,284,703 $597,682 $569,298 $1,214,948 $671,328 ========== ========== ========== ======== ========== ======== Massachusetts Investors Growth Stock Series Mid Cap Value Series New Discovery Series -------------------------- -------------------------- -------------------------- Years Ended December 31, Years Ended December 31, Years Ended December 31, -------------------------- -------------------------- -------------------------- 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) .............................. $2,408,735 $320,560 $2,449,607 $432,782 $-- $-- Long-term capital gain ........................ -- -- 412,730 25,758 -- -- ------------ ------------ ------------ ------------ ------------ ------------ Total distributions ........................... $2,408,735 $320,560 $2,862,337 $458,540 $-- $-- ========== ========== ========== ======== ========== ======== Research International Series Strategic Growth Series Strategic Value Series -------------------------- -------------------------- -------------------------- Years Ended December 31, Years Ended December 31, Years Ended December 31, -------------------------- -------------------------- -------------------------- 2005 2004 2005 2004 2005 2004 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains)(1) ........................... $1,115,634 $530,167 $184,439 $-- $598,886 $194,355 Long-term capital gain ........................ -- -- -- -- 601,688 29,295 ------------ ------------ ------------ ------------ ------------ ------------ Total distributions ........................... $1,115,634 $530,167 $184,439 $-- $1,200,574 $223,650 ========== ========== ========== ======== ========== ======== Technology Series Value Series -------------------------- -------------------------- Years Ended December 31, Years Ended December 31, -------------------------- -------------------------- 2005 2004 2005 2004 - ------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) .............................. $-- $-- $6,089,141 $5,235,208 ------------ ------------ ------------ ------------ (1) Included in Strategic Growth Series' distributions from ordinary income is $983 in excess of investment company taxable income, which in accordance with applicable U.S. tax law, is taxable to shareholders as ordinary income distributions.

Multiple Classes of Shares of Beneficial Interest - Each 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 - Each 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 based on a percentage of each series' average daily net assets as follows: Capital Opportunities Series: The management fee is 0.75% of the first $300 million of average daily net assets and 0.675% of average daily net assets in excess of $300 million.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and the Shareholders of MFS/Sun Life Series Trust: We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of MFS/Sun Life Series Trust (the "Trust"), comprising Capital Opportunities Series, Core Equity Series, International Growth Series, Massachusetts Investors Growth Stock Series, Mid Cap Value Series, New Discovery Series, Research International Series, Strategic Growth Series, Strategic Value Series, Technology Series and Value Series as of December 31, 2005, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements and financial highlights present fairly, in all material respects, the financial positions of Capital Opportunities Series, Core Equity Series, International Growth Series, Massachusetts Investors Growth Stock Series, Mid Cap Value Series, New Discovery Series, Research International Series, Strategic Growth Series, Strategic Value Series, Technology Series and Value Series as of December 31, 2005, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENTS 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, annually approve the continuation of the Trust's investment advisory agreements with Massachusetts Financial Services Company (MFS) on behalf of the Series. The Trustees consider matters bearing on the Series and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July 2005 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreements for the Series. The independent Trustees were assisted in their evaluation of the investment advisory agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS management during various contract review meetings. The independent Trustees were also assisted in this process by the Series' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations, 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 agreements were considered separately for each Series, although the Trustees also took into account the common interests of all Series 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 agreements and other arrangements with the Trust. 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 each Series for various time periods ended December 31, 2004, compared to the investment performance of a group of funds with substantially similar investment classifications/ objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("peer funds"), (ii) information provided by Lipper Inc. on each Series' advisory fees and other expenses compared to 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 its other clients, including 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 a 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, (vi) MFS' views regarding the outlook for the mutual fund industry and its strategic business plans, (vii) descriptions of various functions performed by MFS for the Trust, 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. The comparative performance, 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 continuation of the investment advisory agreements was based on 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 for each Series, while individual Trustees may have given different weight to various factors and evaluated the information presented as a whole differently than another Trustee. The Trustees recognized that the fee arrangements for the Series reflect years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees compared each Series' total return investment performance to the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of each Series' Initial Class shares in comparison to the performance of funds in its Lipper performance universe over the one-, three- and five-year periods. The Trustees did not rely on performance results for more recent periods, including those shown elsewhere in this report. In the course of their deliberations, the Trustees took into account information provided by MFS during contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year. For Series whose performance lagged their peer groups, they discussed MFS' efforts to improve such Series' performance. After reviewing this information, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreements, that they were satisfied with MFS' responses and efforts relating to investment performance. In assessing the reasonableness of each Series' advisory fee, the Trustees considered, among other information, each Series' advisory fee and the total expense ratio of the Series' Initial Class shares as a percentage of average net assets, compared to the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered the generally broader scope of services provided by MFS to the Trust than those provided to institutional accounts. The Trustees also considered 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 related expenses due to the more extensive regulatory regime to which the Series are subject, compared to institutional accounts. The Trustees also considered whether a Series is likely to benefit from any economies of scale due to future asset growth. In this regard, the Trustees reviewed the adequacy of breakpoints, and considered if breakpoints should be implemented for any Series that did not have them. The Trustees also considered information prepared by MFS relating to its costs and profits with respect to the Series and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the Series and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described below, the Trustees concluded 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. 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 the financial resources of MFS and its affiliation with Sun Life Financial Inc. The Trustees further considered any advantages and possible disadvantages of having an adviser which also serves other investment companies as well as institutional 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 agreements, including the 12b-1 fees the Series pay 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 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 Series were satisfactory. The Trustees also considered the benefits to MFS from the use of the Series' portfolio brokerage commissions to pay for research and other similar services (including MFS' current 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 Trust, and determined that any such benefits derived by MFS were reasonable and fair. Based on their evaluation of factors that they deemed to be material, including those factors described above, and the individual Series factors noted below, the Board of Trustees, including a majority of the independent Trustees, concluded that the investment advisory agreements should be continued for an additional one-year period, commencing September 1, 2005. CAPITAL OPPORTUNITIES SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 41st percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 84th percentile for the three-year period and the 83rd percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS and the Series' improving performance, the Board of Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate and total expense ratio were each approximately at the median of such fees and expenses of funds in the Lipper expense group. The Trustees further concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. CORE EQUITY SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 27th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 50th percentile for the three-year period and the 46th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was approximately at, and the total expense ratio was lower than, the median of such fees and expenses of funds in the Lipper expense group. They further noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.10% on net assets over $1 billion, which took effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. INTERNATIONAL GROWTH SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 30th percentile relative to the other funds in the peer universe for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 17th percentile for the three-year period and the 6th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was higher than, and the total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. The Trustees also concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. MASSACHUSETTS INVESTORS GROWTH STOCK SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 30th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 55th percentile for the three-year period and the 45th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate and total expense ratio were each approximately at the median of such fees and expenses of funds in the Lipper expense group. The Trustees further concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. MID CAP VALUE SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 15th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). (The Series had been in existence for less than three years.) Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted that MFS currently observes a voluntary expense limitation for the Series, which may not be changed without the Trustees' approval. The Trustees noted from the Lipper data that the Series' effective advisory fee rate was approximately at, and the total expense ratio was at, the median of such fees and expenses of funds in the Lipper expense group. They also noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.05% on net assets over $1 billion, which took effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. NEW DISCOVERY SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 74th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 78th percentile for the three-year period and the 45th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. The Trustees noted that MFS had made a change in portfolio management responsibilities in February, 2005 in an effort to improve relative performance. Based on the nature and quality of services provided by MFS, and MFS' efforts to improve performance, the Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was higher than, and the total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. They further noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.10% on net assets over $1 billion, which will take effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. RESEARCH INTERNATIONAL SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 16th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 22nd percentile for the three-year period and the 17th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was higher than, and the total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. The Trustees also concluded that the existing breakpoints were sufficient to allow the Series to benefit from economies of scale as its assets grow. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. STRATEGIC GROWTH SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 66th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Series was in the 74th percentile for the three-year period and the 57th percentile for the five-year period ended December 31, 2004, relative to the Lipper performance universe.

In considering the fees, the Trustees noted from the Lipper data that the Series' effective advisory fee rate was at, and the total expense ratio was approximately at, the median of such fees and expenses of funds in the Lipper expense group. They further noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.10% on net assets over $1 billion, which took effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided. STRATEGIC VALUE SERIES The Trustees noted the total return performance of the Series' Initial Class shares was in the 13th percentile relative to the other funds in the Lipper Classification Index for the one-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers) ended December 31, 2004, relative to the Lipper performance universe. (The Series had been in existence for less than three years.) Based on the nature and quality of services provided by MFS, the Board of Trustees concluded that the Series' performance was satisfactory. In considering the fees, the Trustees noted that MFS currently observes a voluntary expense limitation for the Series, which may not be changed without the Trustees' approval. The Trustees noted from the Lipper data that the Series' effective advisory fee rate was lower than, and the total expense ratio was higher than, the median of such fees and expenses of funds in the Lipper expense group. They further noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.10% on net assets over $1 billion, which took effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007.

(The Series had been in existence for less than five years.) In considering performance, the Trustees noted that MFS had made a change in portfolio management responsibilities in March 2005 in order to improve relative performance. Based on the nature and quality of services provided by MFS, and MFS' efforts to improve performance, the Trustees concluded that the Series' performance was adequate. In considering the fees, the Trustees noted that MFS currently observes a voluntary expense limitation for the Series, which may not be changed without the Trustees' approval.

They also noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. Based on these considerations, at the request of the Trustees, MFS agreed to implement an advisory fee contractual breakpoint to reduce the Series' annual advisory fee rate by 0.10% on net assets over $1 billion, which took effect on September 1, 2005, and MFS further agreed to voluntarily reduce the breakpoint to $500 million through April 30, 2007.

(1) The fees included under "Audit-Related Fees" are fees related to assurance and related services that are reasonably related to the performance of the audit or review of financial statements, but not reported under "Audit Fees," including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters and internal control reviews. (2) The fees included under "Tax Fees" are fees associated with tax compliance, tax advice and tax planning, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews and tax distribution and analysis. (3) The fees included under "All Other Fees" are fees for products and services provided by Deloitte other than those reported under "Audit Fees," "Audit-Related Fees" and "Tax Fees," including fees for services related to sales tax refunds, consultation on internal cost allocations, consultation on allocation of monies pursuant to an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales, and analysis of certain portfolio holdings verses investment styles. ITEM 4(e)(1): Set forth below are the policies and procedures established by the Audit Committee of the Board of Trustees relating to the pre-approval of audit and non-audit related services: To the extent required by applicable law, pre-approval by the Audit Committee of the Board is needed for all audit and permissible non-audit services rendered to the Funds and all permissible non-audit services rendered to MFS or MFS Related Entities if the services relate directly to the operations and financial reporting of the Registrant. Pre-approval is currently on an engagement-by-engagement basis. In the event pre-approval of such services is necessary between regular meetings of the Audit Committee and it is not practical to wait to seek pre-approval at the next regular meeting of the Audit Committee, pre-approval of such services may be referred to the Chair of the Audit Committee for approval; provided that the Chair may not pre-approve any individual engagement for such services exceeding $50,000 or multiple engagements for such services in the aggregate exceeding $100,000 between such regular meetings of the Audit Committee. Any engagement pre-approved by the Chair between regular meetings of the Audit Committee shall be presented for ratification by the entire Audit Committee at its next regularly scheduled meeting. ITEM 4(e)(2): None, or 0%, of the services relating to the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund and MFS and MFS Related Entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied). ITEM 4(f): Not applicable. ITEM 4(h): The Registrant's Audit Committee has considered whether the provision by a Registrant's independent registered public accounting firm of non-audit services to MFS and MFS Related Entities that were not pre-approved by the Committee (because such services were provided prior to the effectiveness of SEC rules requiring pre-approval or because such services did not relate directly to the operations and financial reporting of the Registrant) was compatible with maintaining the independence of the independent registered public accounting firm as the Registrant's principal auditors.

SCHEDULE OF INVESTMENTS A schedule of investments of the Registrant is included as part of the report to shareholders of such series under Item 1 of this Form N-CSR. ITEM 7.

ITEM 11. CONTROLS AND PROCEDURES. (a) Based upon their evaluation of the registrant's disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940 (the "Act")) as conducted within 90 days of the filing date of this Form N-CSR, the registrant's principal financial officer and principal executive officer have concluded that those disclosure controls and procedures provide reasonable assurance that the material information required to be disclosed by the registrant on this report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. (b) There were no changes in the registrant's internal controls over financial reporting (as defined in Rule 30a-3(d) under the Act) that occurred during the second fiscal quarter covered by the report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
