The U.S. stock market, as one notable example, posted strong gains as the Dow Jones Industrial Average hit record highs and the Standard & Poor's 500 Stock Index rose to levels not seen since 2000. While investors were undoubtedly encouraged by these positive developments, we think it is important to maintain the proper perspective on what appears to be happening with the world's financial markets. Around the globe, economies seem to have reached a state of equilibrium. Both stock and bond markets have simply been less volatile than they were in years past. While there are many factors behind the low levels of volatility, one of the key reasons is that the U.S. Federal Reserve Board and other central banks around the world seem to have found the right formula for simultaneously promoting economic growth and keeping inflation under control. This new, calmer state of affairs is no doubt welcomed by many investors, but with less volatility, the possibilities for earning exceptional returns also diminish. Investors may have to lower their expectations about what are reasonable returns from the markets. Those still looking for the types of returns they had been accustomed to in the past may have to work much harder to seek out those opportunities and perhaps also accept more risk than they customarily did. In any market climate, even in a relatively benign one, we think investors are still best served by spreading their holdings across a variety of investments that will give them exposure to a range of market opportunities and varying levels of risk. Respectfully, /s/ Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) February 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed. MANAGEMENT REVIEWS The following management reviews, for the twelve months ended December 31, 2006, exclude the Money Market Series. BOND SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 5.20%, while Service Class shares provided a total return of 4.87%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 3.77% for the series' benchmark, the Lehman Brothers U.S. Government/Credit Bond Index. CONTRIBUTORS TO PERFORMANCE Yield was a positive factor contributing to the portfolio's relative performance. Overweighting "BB" and "B" rated(s) bonds also bolstered results as spreads narrowed over the period. The portfolio's shorter duration(d) stance helped performance as interest rates rose. Corporate bonds in the industrial and finance sectors also aided performance as those sectors outperformed the benchmark. In the finance sector, bonds of Ford Motor Credit and General Motors Acceptance Corp. (GMAC) were among the top contributors. DETRACTORS FROM PERFORMANCE Security selection detracted from relative returns over the period. Individual holdings that held back results included casino operator Harrah's, hospital operator HCA, and pipeline company Kinder Morgan, all of which announced leveraged buyouts (LBOs) during the period. EMERGING MARKETS EQUITY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 30.16%, while the Service Class shares provided a total return of 29.90%. These returns do not reflect any applicable surrender or contract charges and compare with a return of 32.59% for the series' benchmark, the MSCI Emerging Markets Index. DETRACTORS FROM PERFORMANCE Stock selection in the financial services sector was the principal negative factor in the portfolio's relative performance. Credit card administration services provider CSU CardSystem(c)(g) (Brazil) and banking firm Kookmin Bank (South Korea) were among the top detractors from relative returns. Not owning China Life Insurance (Hong Kong) held back relative performance as this stock performed significantly better than the benchmark. Stock selection and, to a lesser extent, our overweighted position in the technology sector also detracted from results. Overweighting electronics manufacturer Samsung Electronics (South Korea) dampened relative performance as Samsung underperformed the benchmark. Samsung's stock price suffered due to disappointing earnings in the first half of the reporting period. Elsewhere, generic drug manufacturer Teva Pharmaceuticals(g) (Israel), Latin American provider of airline passenger and cargo services Copa Holdings(c)(g), and mobile phone services provider Egypt Mobile Phone(g) held back results. Not owning strong-performing Latin American wireless communications company America Movil and our positioning in technology consulting firm Infosys Technologies(g) (India) also hurt. 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. CONTRIBUTORS TO PERFORMANCE Stock selection in the autos and housing sector boosted relative performance. Not owning weak-performing electronics manufacturer LG Electronics (South Korea) was a factor in this result. Stock selection in the utilities and communications sector also helped. Wireless communications company China Mobile (Hong Kong) and mobile phone services provider Vimpel Communications(g) (Russia) were among the portfolio's top contributors. Our underweighted position in natural gas producer Gazprom (Russia) benefited relative performance as this stock underperformed the benchmark. Stocks in other sectors that aided relative returns included four Brazilian companies: iron ore miner Companhia Vale do Rio Doce, railroad-based logistics operator All America Latina Logistica(g), oil and gas exploration and production company Petroleo Brasileiro, and financial services firm Banco Nossa Caixa. Our favorable positioning in banking firm Turkiye Is Bankasi(g) (Turkey), and in gold producer Polyus Gold(g) (Russia) also helped. During the reporting period, 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. GLOBAL GOVERNMENTS SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 4.97%, while Service Class shares provided a total return of 4.70%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 5.94% for the series' benchmark, the JPMorgan Global Government Bond Index. DETRACTORS FROM PERFORMANCE Although yield was a factor that negatively affected the portfolio's relative performance, this was more than offset by the benefit from the portfolio's short bond position in Japan. The portfolio's positioning in bonds from the United Kingdom and New Zealand also held back results. CONTRIBUTORS TO PERFORMANCE The portfolio's short duration(d) stance contributed to performance throughout the period. Our underweighted position in U.S. dollars and our overweighted position in the Euro also helped. Sector and security selection in U.S. and EMU (European Monetary Unit) bonds contributed to results, as did our emerging markets exposure. GLOBAL TOTAL RETURN SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 17.20%, while Service Class shares provided a total return of 16.91%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 20.65% for the series' benchmark, the MSCI World Index. The series' other benchmark, a hybrid benchmark comprised of 60% of the MSCI World Index and 40% of the JPMorgan Global Government Bond Index, provided a total return of 14.64%. DETRACTORS FROM PERFORMANCE Within the equity portion of the portfolio, stock selection in the financial services and leisure sectors held back performance relative to the MSCI World Index. Within financial services, some of our holdings in Japanese financial services firms were among the portfolio's top detractors during the reporting period. These included consumer financing firms Aiful and Takefuji. Both companies struggled during the period in an increasingly difficult regulatory and business environment for consumer finance companies. Security selection in the utilities and communications sector also hurt relative results. Wireless services company Sprint Nextel and communications company Telecom Corp. of New Zealand(g) detracted from relative returns. Shares of Sprint Nextel suffered after the company lowered its wireless subscriber guidance for 2006. Also, the company's merger with Nextel appeared to have disappointed investors. Not owning communications services providers AT&T and BellSouth, both strong-performing benchmark constituents, also dampened performance. Elsewhere, convenience store operator Lawson (Japan), home improvements products maker Masco, and electronics manufacturer Samsung Electronics(c) (South Korea) hurt relative performance. The cash position in the equity portion of the portfolio was also a detractor from relative performance. As with nearly all mutual funds, this 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. Within the fixed income portion of the portfolio, our holdings in government agency debt detracted from relative results. Although yield was a factor that negatively affected the portfolio's relative performance, this was more than offset by the benefit from the portfolio's short bond position in Japan. CONTRIBUTORS TO PERFORMANCE Security selection and, to a lesser extent, our underweighting in both the technology and health care sectors benefited relative performance. Our holdings in pharmaceutical manufacturer Schering(g) (Germany) performed particularly well within the health care sector as its share price soared following a takeover offer from rival company Bayer. No individual holdings within the technology sector were among the portfolio's top contributors. Stock selection in the energy sector also contributed to relative results as steel tube manufacturer Vallourec(g) (France) and oil and gas company Norsk Hydro (Norway) gained substantially over the period. Several individual holdings significantly aided performance including agrichemical products maker Syngenta (Switzerland) and defense contractor Lockheed Martin. Syngenta benefited from increased sales volume, especially in North America, driven largely by its newer product portfolio and strong distribution network. Lockheed Martin gained on strong revenue growth, improved margins, and key contract awards over the period. Other stocks that helped relative results included investment banking firm Goldman Sachs, plumbing equipment maker Geberit (Switzerland), and electric power distributor SUEZ (France). During the reporting period, currency exposure in the equity portion of the portfolio 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. Within the fixed income portion of the portfolio, our duration(d) stance boosted relative results. The portfolio's exposure to the Euro and the Swedish Krona also helped. GOVERNMENT SECURITIES SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 3.68%, while Service Class shares provided a total return of 3.47%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 4.35% for the series' benchmark, the Lehman Brothers U.S. Government/Mortgage Bond Index. DETRACTORS FROM PERFORMANCE Relative to the benchmark, our positioning in Israeli government debt held back relative returns. Within the agency sector, a Tennessee Valley Authority (TVA) bond, which underperformed the agency sector as a whole, was among the top detractors. CONTRIBUTORS TO PERFORMANCE The portfolio's overweighted position in agency securities contributed to relative performance as the sector outperformed the overall benchmark over the reporting period. Holdings of mortgage-backed securities also helped. HIGH YIELD SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 10.39%, while Service Class shares provided a total return of 10.04%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 11.87% for the series' benchmark, the Lehman Brothers U.S. High-Yield Corporate Bond Index. DETRACTORS FROM PERFORMANCE Yield was a negative factor in performance relative to the Lehman Brothers U.S. High-Yield Corporate Bond Index, as was our relative exposure to "BB" rated(s) bonds. Holdings of hospital operator HCA and gaming company Station Casinos were among the portfolio's largest detractors. CONTRIBUTORS TO PERFORMANCE Our positioning in "B" rated securities helped relative performance over the reporting period. Individual contributors that aided relative results included broadband communications company CCH Holdings, financing company General Motors Acceptance Corp. (GMAC), and packaging company Smurfit Kappa(g). INTERNATIONAL VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 29.23%, while the Service Class shares provided a total return of 28.95%. These returns do not reflect any applicable surrender or contract charges and compare with a return of 31.05% for the series' benchmark, the MSCI EAFE Value Index. The series' other benchmark, the MSCI EAFE Index, provided a return of 26.86%. DETRACTORS FROM PERFORMANCE Stock selection in the financial services sector was a significant detractor from performance relative to the MSCI EAFE Value Index. Two Japanese consumer finance firms, Aiful and Takefuji, had particularly disappointing performance. Both firms struggled during the period in an increasingly difficult regulatory, business, and media environment for consumer finance firms. Elsewhere, electronics manufacturer Samsung Electronics(c) (South Korea) hindered results. Shares of Samsung suffered as a result of disappointing earnings in the first half of the period. Other detractors included pharmaceutical company GlaxoSmithKline(c) (United Kingdom), apparel products and accessories retailer Impact 21(c) (Japan), convenience store chain Lawson (Japan), pharmaceutical company Novartis(c) (Switzerland), and electronics manufacturer Samsung SDI(c) (South Korea). Not owning steel producer Arcelor Mittal (Luxembourg) also hurt as this company's stock outperformed the benchmark. During the reporting period, 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. 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 in the energy sector contributed to performance relative to the MSCI EAFE Value Index. Steel tube manufacturer Vallourec(c)(g) (France) was the largest contributor to the portfolio's relative return. The company's strong performance was driven by price increases of its seamless tubes and low levels of exposure to price fluctuations of raw materials. Other stocks within this sector that helped performance included energy company Royal Dutch Shell (Netherlands) and seismographic services and equipment firm Compagnie Generale de Geophysique(c)(g) (France). Stock selection in the autos and housing sector also bolstered results. Within this sector, plumbing equipment maker Geberit(c) (Switzerland) was among the portfolio's top contributors. Stocks in other sectors that contributed to relative performance included pharmaceutical company Schering(c)(g) (Germany), agrochemical company Syngenta(c) (Switzerland), home improvement retailer Praktiker Bau-und Heimwerkermarkte(c) (Germany), telecommunications company Telenor(c) (Norway), biopharmaceutical company Actelion(c) (Switzerland), and grocery store chain Morrison Supermarkets(c)(g) (United Kingdom). STRATEGIC INCOME SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 6.71%, while Service Class shares provided a total return of 6.45%. 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: 9.88% for the JPMorgan Emerging Markets Bond Index Global, 11.87% for the Lehman Brothers U.S. High-Yield Corporate Bond Index, 3.10% for the Citigroup World Government Bond Non-Dollar Hedged Index, and 4.33% for the Lehman Brothers U.S. Aggregate Bond Index. DETRACTORS FROM PERFORMANCE The portfolio's underweighted position in "B" rated(s) securities held back performance during the reporting period. Our positioning in New Zealand government debt also hurt. Among individual holdings, hospital operator HCA was a top detractor. CONTRIBUTORS TO PERFORMANCE Our short duration(d) stance contributed to the portfolio's performance as interest rates rose over the reporting period. Corporate bonds in the bank and finance sector and our positioning in Argentinian government debt also helped. Bonds of General Motors Acceptance Corp. (GMAC) and Ford Motor Credit were among the portfolio's top contributors. (c) Security is not a benchmark constituent. (d) Duration is a measure of how much a bond's price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a bond with a 5-year duration is likely to lose about 5.00% of its value. (g) Security was not held in the portfolio at period end. (s) Bonds rated "BBB", "Baa", or higher are considered investment grade; bonds rated "BB", "Ba", or below are considered non-investment grade. The primary source for bond quality ratings is Moody's Investors Service. If not available, ratings by Standard & Poor's are used, else ratings by Fitch, Inc. For securities which are not rated by any of the three agencies, the security is considered Not Rated.

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 such subsidies and waivers the series' performance results would be less favorable. Please see the prospectus and financial statements for complete 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. EXPENSE TABLES SERIES EXPENSES BORNE BY THE CONTRACT HOLDERS DURING THE PERIOD, JULY 1, 2006 THROUGH DECEMBER 31, 2006 As a contract holder of each series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. The examples are intended to help you understand your ongoing costs (in dollars) of investing in each series and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period, July 1, 2006 through December 31, 2006. 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 each series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each 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 each 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 each series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in each 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 each 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 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 insurance companies 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. The 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. Each series (except the Money Market Series and Government Securities 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 under 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 reported that day, equity securities are generally valued at the last quoted daily bid quotation 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 or composite bid 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 60 days or less may be valued at amortized cost, which approximates market value. Exchange-traded options are generally valued at the last sale or official closing price as reported by an independent pricing service on the exchange on which they are primarily traded. Exchange-traded options for which there were no sales reported that day are generally valued at the last daily bid quotation 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 at a broker-dealer bid quotation. 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 last posted settlement price as reported by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as reported by an independent pricing service on the market on which they are primarily traded. Forward foreign currency contracts are generally valued at the mean of bid and asked prices for the time period interpolated from rates reported by an independent pricing service for proximate time periods. Swaps are generally valued at a broker-dealer bid quotation. 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 at a broker-dealer bid quotation. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates reported by an independent pricing service. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the series' investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the series' valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments. These investments are generally valued at fair value based on information from independent pricing services. In addition, investments may be valued at fair value if the adviser determines that an investment's value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the series' net asset value, or after the halting of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. Events that occur on a frequent basis after foreign markets close (such as developments in foreign markets and significant movements in the U.S. markets) and prior to the determination of the series' net asset value may be deemed to have a material affect on the value of securities traded in foreign markets. Accordingly, the series' foreign equity securities may often be valued at fair value. The adviser may rely on independent pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the series' net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine the series' net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the series, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in each series' financial statements. 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 - Certain 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 purchased options, futures contracts, forward foreign currency exchange contracts, and swap agreements. Purchased Options - Certain 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 - Certain 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 each series. Upon entering into such contracts, each series bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the series may not achieve the anticipated benefits of the futures contracts and may realize a loss. Forward Foreign Currency Exchange Contracts - Certain 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 - Certain 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with each series' custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by each series with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. Credit Default Swaps - In a credit default swap, one party makes a stream of payments based on a fixed percentage applied to the notional amount 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. Each series may enter into credit default swaps to limit or to reduce its risk exposure to defaults of corporate and sovereign issuers or to create direct or synthetic short or long exposure to corporate debt securities or certain sovereign debt securities to which it is not otherwise exposed. Security Loans - State Street Bank and Trust Company ("State Street"), as lending agent, 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 provides 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 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. Loans and Other Direct Debt Instruments - Certain series may invest in loans and loan participations or other receivables. These investments may include standby financing commitments, including revolving credit facilities, which obligate the series to supply additional cash to the borrower on demand. Loan participations involve a risk of insolvency of the lending bank or other financial intermediary. Indemnifications - Under each series' organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the series. Additionally, in the normal course of business, each series enters into agreements with service providers that may contain indemnification clauses. Each series' maximum exposure under these agreements is unknown as this would involve future claims that may be made against the series that have not yet occurred. 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. 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. For all other series, all premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles; and all discount is accreted for tax reporting purposes as required by federal income tax regulations. Certain series earn certain fees in connection with their floating rate loan purchasing activities. These fees are in addition to interest payments earned and may include amendment fees, commitment fees, facility fees, consent fees, and prepayment fees. These fees are recorded on an accrual basis as income in the accompanying financial statements. Dividends received in cash are recorded on the ex-dividend date. Certain dividends from foreign securities will be recorded when 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 Statement 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 fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the series. This amount, for the year ended December 31, 2006, is shown as a reduction of total expenses on the Statements of Operations. Tax Matters and Distributions - Each series intends to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable income, including realized capital gains. 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 U.S. 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 overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Book/tax differences primarily relate to expiration of capital loss carryforwards, amortization and accretion of debt securities, defaulted bonds, passive foreign investment companies, wash sale loss deferrals, straddle loss deferrals, foreign currency transactions, derivative transactions, and foreign taxes. The tax character of distributions declared to shareholders is as follows: Emerging Markets Bond Series Equity Series Global Governments Series -------------------------- ------------------------- ------------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ............................. $12,531,880 $14,157,639 $ 6,817,904 $ 488,024 $ 458,662 $ 6,705,443 Long-term capital gain ....................... 1,203,795 3,592,851 9,678,740 272,379 -- 96,874 ----------- ----------- ----------- ----------- ----------- ----------- Total distributions ........................ $13,735,675 $17,750,490 $16,496,644 $ 760,403 $ 458,662 $ 6,802,317 =========== =========== =========== =========== =========== =========== Government Global Total Return Series Securities Series High Yield Series -------------------------- ------------------------- ------------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ............................. $ 2,629,612 $10,130,137 $31,964,775 $31,699,880 $29,158,470 $31,907,573 Long-term capital gain ....................... 10,609,279 8,623,607 -- -- -- -- ----------- ----------- ----------- ----------- ----------- ----------- Total distributions ........................ $13,238,891 $18,753,744 $31,964,775 $31,699,880 $29,158,470 $31,907,573 =========== =========== =========== =========== =========== =========== International Value Series Money Market Series Strategic Income Series -------------------------- ------------------------- ------------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ............................. $ 6,463,756 $ 1,161,124 $17,603,606 $ 9,660,955 $ 4,885,515 $ 6,201,359 Long-term capital gain ....................... 9,464,425 2,077,175 -- -- 618,624 625,839 ----------- ----------- ----------- ----------- ----------- ----------- Total distributions ........................ $15,928,181 $ 3,238,299 $17,603,606 $ 9,660,955 $ 5,504,139 $ 6,827,198 =========== =========== =========== =========== =========== =========== The federal tax cost and the tax basis components of distributable earnings were as follows: Emerging Global Bond Markets Equity Governments AS OF 12/31/06 Series Series Series - --------------------------------------------------------------------------------------------------- Cost of investments ............................. $196,572,458 $83,514,883 $43,443,352 ------------ ----------- ----------- Gross appreciation .............................. 2,071,544 26,494,207 743,588 Gross depreciation ..............................

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the "Interpretation") was issued, and is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management is evaluating the application of the Interpretation to the series, and has not at this time determined the impact, if any, resulting from the adoption of this Interpretation on the series' financial statements. 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 management and related administrative services and 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: 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. At the commencement of the period, and until August 31, 2006, the investment adviser had agreed in writing to reduce its management fee to 0.70% of average daily net assets in excess of $1 billion. Effective September 1, 2006, the investment adviser has agreed in writing to reduce its management fee to 0.70% of the first $1.0 billion of average daily net assets and 0.65% of average daily net assets in excess of $1 billion. This written agreement will continue through August 31, 2007 unless changed or rescinded by the series' Board of Trustees. This management fee reduction amounts to $58,752, which is shown as a reduction of total expense in the Statement of Operations. 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 agreed in writing to reduce its management fee to 0.45% of average daily net assets in excess of $500 million. This written agreement may be rescinded only upon consent of the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. Strategic Income Series: The management fee is 0.75% of the first $1.0 billion of average daily net assets and 0.65% of average daily net assets in excess of $1 billion. At the commencement of the period, and until August 31, 2006, the investment adviser had agreed in writing to reduce its management fee to 0.65% of average daily net assets in excess of $500 million. Effective September 1, 2006, the investment adviser has agreed in writing to reduce its management fee to 0.70% of the first $1.0 billion of average daily net assets. This written agreement will continue through August 31, 2007 unless changed or rescinded by the series' Board of Trustees. This management fee reduction amounts to $12,810, which is shown as a reduction of total expense in the Statement of Operations. Effective September 1, 2006, the investment adviser has agreed in writing to pay a portion of certain series' operating expenses, exclusive of certain other fees and expenses, such that the total annual 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 incurred for the year ended December 31, 2006 were equivalent to an annual effective rate of each series' average daily net assets as follows. In addition, the expense limitations incurred for the year ended December 31, 2006 were as follows: Effective Initial Class Service Class Management Expense Expense Fees Limitation Limitation - -------------------------------------------------------------------------------- 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%(a) 1.25%(a) High Yield Series ................. 0.73% 1.00%(a) 1.25%(a) International Value Series ........ 0.90% N/A N/A Money Market Series ............... 0.50% 0.60%(a) 0.85%(a) Strategic Income Series ........... 0.73% 0.90%(b) 1.15%(b) (a) MFS' agreement to limit the series' operating expenses, exclusive of certain other fees and expenses, to 1.25% of the series' average daily net assets is contained in the investment advisory agreement between MFS and the series and may not be rescinded without shareholder approval. MFS' agreement to limit the series' operating expenses, exclusive of certain other fees and expenses, to 1.00% of the series' average daily net assets attributable to Initial Class shares (0.60% for Money Market Series Initial Class shares and 0.85% for Money Market Series Service Class shares) may be changed or rescinded at any time by MFS. (b) This written agreement became effective on September 1, 2006, and will continue through August 31, 2007 unless changed or rescinded by the series' Board of Trustees. For the year ended December 31, 2006, these reductions amounted to the following for each series and is reflected as a reduction of total expenses in the Statements of Operations: Expense Reduction - ------------------------------------------------------------------------------- Global Government Series ........................................ $61,974 Strategic Income Series ......................................... $ 4,278 For the year ended December 31, 2006, the actual operating expenses for Government Securities Series, High Yield Series, and Money Market Series did not exceed the limit and therefore, the investment adviser did not pay any portion of these series' expenses. 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. Under an administrative services agreement, each series partially reimburses MFS the costs incurred to provide these services. Prior to June 1, 2006, each series was allocated a portion of these administrative costs based on its size and relative average net assets. Effective June 1, 2006, each series is charged an annual fixed amount of $10,000 plus a fee based on calendar year average net assets. The administrative services fee incurred for the year ended December 31, 2006 was equivalent to an annual effective rate of each series' average daily net assets as follows. % of Average Daily Net Assets - ------------------------------------------------------------------------------- Bond Series ............................................... 0.0247% Emerging Markets Equity Series ............................ 0.0244% Global Governments Series ................................. 0.0242% Global Total Return Series ................................ 0.0248% Government Securities Series .............................. 0.0242% High Yield Series ......................................... 0.0246% International Value Series ................................ 0.0249% Money Market Series ....................................... 0.0250% Strategic Income Series ................................... 0.0245% 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 or officers of the series who are also officers of the investment adviser, all of whom receive remuneration for their services to the series from MFS. Certain officers and trustees of the series are officers or directors of MFS, MFD, and MFSC. Other - These series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. For the year ended December 31, 2006, payments made by the series to Tarantino LLC amounted to the following and are included in the miscellaneous expense on the Statements of Operations: ICCO Fee - ------------------------------------------------------------------------------- Bond Series ....................................................... $1,061 Emerging Markets Equity Series .................................... 524 Global Governments Series ......................................... 242 Global Total Return Series ........................................ 909 Government Securities Series ...................................... 3,382 High Yield Series ................................................. 1,814 International Value Series ........................................ 696 Money Market Series ............................................... 2,045 Strategic Income Series ........................................... 401 (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than purchased option transactions and short-term obligations, were as follows: Emerging Global Bond Markets Equity Governments Global Total Series Series Series Return Series - ----------------------------------------------------------------------------------------------------------------------------------- Purchases U.S. government securities ...................................... $ 6,733,178 $ -- $18,210,239 $ 31,050,608 Investments (non-U.S. government securities) .................... $ 89,034,409 $111,955,027 $26,805,538 $ 91,390,280 Sales U.S. government securities ...................................... $ 14,779,065 $ -- $15,819,245 $ 26,737,741 Investments (non-U.S. government securities) .................... $ 99,959,169 $120,997,622 $36,303,651 $122,192,574 Government Securities High Yield International Strategic Series Series Value Series Income Series - ----------------------------------------------------------------------------------------------------------------------------------- Purchases U.S. government securities ...................................... $186,019,868 $ 6,945,838 $ -- $ 547,566 Investments (non-U.S. government securities) .................... $ 60,366 $300,257,114 $72,870,125 $47,756,526 Sales U.S. government securities ...................................... $186,137,372 $ -- $ -- $ 3,731,938 Investments (non-U.S. government securities) .................... $ 2,548,037 $321,765,611 $74,657,102 $53,010,575 Purchases and sales of investments for the Money Market Series, which consist solely of short-term obligations, amounted to $6,070,800,047 and $5,978,435,257, respectively, excluding repurchase agreements.

In addition, each series and other funds managed by MFS have established uncommitted borrowing arrangements with certain banks. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee based on the average daily, unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. For the year ended December 31, 2006, each series' commitment fee and interest expense were as follows and are included in miscellaneous expense on the Statements of Operations: Commitment Interest Fee Expense - ------------------------------------------------------------------------------- Bond Series ......................................... $1,757 $ -- Emerging Markets Equity Series ...................... 842 6,248 Global Governments Series ........................... 411 -- Global Total Return Series .......................... 1,500 -- Government Securities Series ........................ 5,568 1,801 High Yield Series ................................... 2,924 -- International Value Series .......................... 1,112 -- Money Market Series ................................. 4,596 3,562 Strategic Income Series ............................. 659 -- 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, 2006, 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, 2006, 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, 2006, 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 2006 ("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 of the Series 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, 2005, 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' conclusions as to the continuation of the investment advisory agreements were 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 the factors that contributed thereto and 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 other comparable 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 discussed with MFS any adjustments necessary for the shareholders' benefits. 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 parent, 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' policy not to use "soft dollars" generated by fund 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, 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, 2006. BOND SERIES The Trustees noted the performance of the Series' Initial Class shares was in the 5th quintile relative to the other funds in the Lipper performance universe for the one-year period (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Series was in the 1st quintile for the three-year period and the 1st quintile for the five-year period ended December 31, 2005, 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 above the median and the total expense ratio was approximately at the median of such fees and expenses of funds in the Lipper expense group. They noted that the Series' advisory fee rate schedule is not currently subject to any breakpoints. However, the Trustees concluded that the fees were reasonable in light of the nature and quality of services provided by MFS, and determined not to recommend any advisory fee breakpoints for the Series at this time. EMERGING MARKETS EQUITY SERIES The Trustees noted the performance of the Series' Initial Class shares was in the 2nd quintile relative to the other funds in the Lipper performance universe for the one-year period (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Series was in the 1st quintile for the three-year period and the 2nd quintile for the five-year period ended December 31, 2005, 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 the median and total expense ratio was below 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.

The U.S. stock market, as one notable example, posted strong gains as the Dow Jones Industrial Average hit record highs and the Standard & Poor's 500 Stock Index rose to levels not seen since 2000. While investors were undoubtedly encouraged by these positive developments, we think it is important to maintain the proper perspective on what appears to be happening with the world's financial markets. Around the globe, economies seem to have reached a state of equilibrium. Both stock and bond markets have simply been less volatile than they were in years past. While there are many factors behind the low levels of volatility, one of the key reasons is that the U.S. Federal Reserve Board and other central banks around the world seem to have found the right formula for simultaneously promoting economic growth and keeping inflation under control. This new, calmer state of affairs is no doubt welcomed by many investors, but with less volatility, the possibilities for earning exceptional returns also diminish. Investors may have to lower their expectations about what are reasonable returns from the markets. Those still looking for the types of returns they had been accustomed to in the past may have to work much harder to seek out those opportunities and perhaps also accept more risk than they customarily did. In any market climate, even in a relatively benign one, we think investors are still best served by spreading their holdings across a variety of investments that will give them exposure to a range of market opportunities and varying levels of risk. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) February 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed. MANAGEMENT REVIEWS CAPITAL APPRECIATION SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 6.37%, while Service Class shares provided a total return of 6.05%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 9.07% for the series' benchmark, the Russell 1000 Growth Index. DETRACTORS FROM PERFORMANCE Our overweighted position in the technology sector held back performance relative to the benchmark. Technology stocks that detracted from results included networking chip maker Marvell Technology Group(c), data storage systems provider EMC, flash memory products maker SanDisk, and producer of thin-film transistor liquid crystal displays (TFT-LCDs) LG Philips(c)(g). The sources of underperformance at Marvell included a dilutive acquisition, a stock options backdating investigation, and disappointing second and third quarter results. EMC's stock suffered after the company lowered earnings guidance. Stock selection in the financial services and retailing sectors dampened relative results over the reporting period. In the financial services sector, education loans lender SLM Corp. (Sallie Mae) hindered relative returns. Within the retailing sector, specialty apparel retailer Chico's and home products retailer Williams-Sonoma were among the portfolio's top detractors. Disappointing earnings guidance and sales trends at Chico's hurt the stock's performance. An underweighted position in the industrial goods and services sector and stock selection in the leisure sector also hurt results. No individual stocks within either of these sectors were among the portfolio's top detractors. Other individual securities that hurt relative performance included biotechnology firm Genzyme, cardiovascular medical devices manufacturer St. Jude Medical, and medical device maker Advanced Medical Optics. Shares of Genzyme declined after the company missed their first quarter earnings target and reported slightly lower sales for Fabrazyme and Synvisc. Higher operating expenses also held back the stock's performance. Advanced Medical Optics struggled after the company lowered its earnings guidance for 2007. Management cited a slowdown in laser vision correction procedures and a slower-than- expected uptake of its multifocal intraocular lenses, especially in Europe, as reasons for its dampened outlook. CONTRIBUTORS TO PERFORMANCE Stock selection in the basic materials sector aided relative returns, although no individual stocks within this sector were among the portfolio's top contributors. Several names in leisure and retailing sectors helped overall relative performance. These included casino resorts operator Las Vegas Sands, slot machine maker International Game Technology, and discount department store Kohl's(g). Shares of Kohl's gained from strong results for the second quarter, with earnings well above guidance. In addition, the company's margins continued to improve due to inventory management initiatives implemented in the last few years. Elsewhere, biotechnology firm Gilead Sciences(g), software giant Oracle, billing software company Amdocs Ltd.(c), biotechnology company Celgene, and network equipment company Cisco Systems were strong contributors over the period. Cisco's shares rose as the company reported strong earnings. In the latter half of the period, the company released better-than-expected fiscal second quarter guidance and reiterated their confidence that the company's full year earnings would be at the high end of their projected range. Our positioning in wireless communications software company QUALCOMM and underweighted position in industrial conglomerate General Electric stock also helped. EMERGING GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 8.02%, while Service Class shares provided a total return of 7.70%. These returns do not reflect any contract or surrender charges and compare with a return of 9.46% for the series' benchmark, the Russell 3000 Growth Index. DETRACTORS FROM PERFORMANCE Stock selection in the technology sector hurt performance relative to the benchmark. Online information portal Yahoo!, network equipment manufacturer Juniper Networks, network chip maker Marvell Technology Group(c), and flash memory storage products maker SanDisk were among the portfolio's largest detractors. The share price of Yahoo! declined as growth in their advertising business and premium branded business slowed. Stock selection in the health care sector also had a negative impact on relative returns. Medical device maker Advanced Medical Optics and cardiovascular medical devices maker St. Jude Medical were significant detractors. Advanced Medical Optics struggled after the company lowered its earnings guidance for 2007. Management cited a slowdown in laser vision correction procedures and a slower-than-expected uptake of its multifocal intraocular lenses as reasons for its dampened outlook. Our underweighted position in the strong-performing industrial goods and services sector held back relative performance. Our overweighted position in industrial automation products maker Rockwell Automation detracted as this stock underperformed the benchmark. Stocks in other sectors that hindered results included online auctioneer eBay, multimedia image provider Getty Images(g), and specialty apparel retailer Chico's(g). CONTRIBUTORS TO PERFORMANCE Stock selection in the financial services sector was a strong contributor to relative returns. Within this sector, two financial exchanges, Euronext(c)(g) and Chicago Mercantile Exchange Holdings, were top contributors. Shares of Euronext skyrocketed early in the year on strong fundamental performance and speculation that it was a possible acquisition target. Later in the period, Euronext announced that it had agreed to a merger proposal from the NYSE Group. Stock selection and our overweighted position in the strong-performing utilities and communications sector also had a positive effect on the portfolio's relative returns. Broadcast and communication tower management firm American Tower and Latin American wireless communications company America Movil(c) bolstered results. Elsewhere, casino resorts operator Las Vegas Sands, biotechnology firm Celgene, billing software company Amdocs Ltd.(c), e-commerce company Submarino(c) (Brazil), and Internet search provider Baidu.com(c) (China) aided relative returns. Our underweighted position in poor-performing semiconductor company Intel also helped as the stock underperformed the benchmark. During the reporting period, 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. GLOBAL GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 17.37% while the Service Class shares provided a total return of 17.09%. These returns do not reflect any applicable surrender or contract charges and compare with a return of 16.74% for the series' benchmark, the MSCI All Country World Growth Index. The series' other benchmark, the MSCI World Growth Index, provided a return of 15.48%. CONTRIBUTORS TO PERFORMANCE Stock selection in the retailing sector was a positive factor in performance relative to the MSCI All Country World Growth Index. Consumer products exporter Li & Fung (Hong Kong) was the portfolio's largest relative contributor. The company's shares gained on strong revenue growth and improved margins during the period. We feel that Li & Fung's acquisition of a private label buying division, which will allow the company to expand its European business, also had a positive impact on its stock. Supermarkets and convenience stores operator Tesco (United Kingdom) also supported this sector's results. Stock selection in the utilities and communications and energy sectors were also positive factors in relative returns. In the utilities and communications sector, telecommunications company Telenor (Norway), electric utility company Iberdrola(g) (Spain), and wireless communications company China Mobile (Hong Kong) were among the portfolio's top contributors. In the energy sector, global seamless steel pipe manufacturer Tenaris(g) made a positive contribution. Stock selection and an overweighted position in the strong-performing consumer staples sector also helped, although no individual securities within this sector were among the top contributors. Stocks in other sectors that bolstered results included paper products manufacturer Aracruz Celulose(c) (Brazil), financial services firm Bank of Cyprus, wealth management firm Julius Baer Holdings(c) (Switzerland), and investment banking firm Goldman Sachs. During the reporting period, 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 Stock selection in the health care sector detracted from performance relative to the benchmark. Medical device maker Cyberonics(c)(g) was among the largest detractors in the portfolio. Cyberonics' stock price declined after the company lowered revenue guidance for their first fiscal quarter of 2007 and delayed expectations for profitability. An investigation into the company's stock options practices led to uncertainty as to whether NASDAQ would delist its stock. Stock selection in the special products and services sector also negatively affected relative returns. The weak performance of multimedia image provider Getty Images(g) and online auctioneer eBay held back results. Getty Images' stock fell due to a slowing image market that led to a depressed revenue trend. Elsewhere, weakness in consumer finance firms AEON Credit Services (Japan) and Aiful(c)(g) (Japan), network equipment manufacturer Juniper Networks(g), industrial adhesive tape maker Nitto Denko (Japan), electronic products manufacturer and seller Hirose Electric, networking chip maker Marvell Technology Group, and children and infant clothing and accessories retailer Nishimatsuya Chain(c)(g) (Japan) had negative impacts on relative returns. MASSACHUSETTS INVESTORS TRUST SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 13.30%, while Service Class shares provided a total return of 13.04%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 15.79% for the series' benchmark, the Standard & Poor's 500 Stock Index (S&P 500 Index). DETRACTORS FROM PERFORMANCE A combination of stock selection and an underweighted position in the utilities and communications sector held back relative performance. In particular, not owning strong-performing telecommunications companies AT&T and Bellsouth hindered results. In the healthcare sector, a combination of stock selection and an overweighted position in this sector had a negative impact on relative returns. Biotechnology firm Amgen and generic drug manufacturer Teva Pharmaceutical(c) were among the portfolio's top detractors. Shares of Amgen fell due to potential competitive pressures on the company's highly profitable anemia franchise. Stock selection in the leisure sector also dampened relative results, though no individual stocks in this sector were among the portfolio's top detractors. A number of individual securities in other sectors held back relative performance. Specialty apparel retailer Chico's(c) was the portfolio's top detractor. Chico's shares came under pressure following tepid same store sales results and weaker-than-expected financial performance. Other detractors included data storage systems provider EMC Corp., energy exploration and production company EOG Resources, flash memory storage products maker SanDisk, and financial services firms SLM Corp. (Sallie Mae) and Legg Mason(g). CONTRIBUTORS TO PERFORMANCE The consumer staples, industrial goods and services, and special products and services sectors were the top contributors to performance relative to the benchmark during the reporting period. Stock selection played the major role in each case. In the consumer staples sector, household products manufacturer Reckitt Benckiser(c) and alcoholic beverages producer Diageo(c) were among the portfolio's top relative contributors. Reckitt Benckiser performed well as the company realized both sales and cost synergies from the Boots Healthcare acquisition earlier than expected and once again posted strong earnings. Within the industrial goods and services sector, defense contractor Lockheed Martin and industrial manufacturer Caterpillar(g) boosted relative returns. Shares of Lockheed Martin reacted strongly to significantly better-than- expected earnings results throughout the year coupled with some exciting new contract announcements (the Orion space shuttle replacement program was a highlight). Not owning stock in diversified industrial conglomerate General Electric also benefited results. In the special products and services sector, billing software company Amdocs Ltd.(c) contributed to relative returns. Stocks in other sectors that helped relative results included investment banking firm Goldman Sachs Group, discount department store Kohl's(g), network equipment company Cisco Systems, and software giant Oracle. During the reporting period, currency exposure was a contributor to 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. MID CAP GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 2.34%, while Service Class shares provided a total return of 2.20%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 10.66% for the series' benchmark, the Russell Midcap Growth Index. DETRACTORS FROM PERFORMANCE The technology, retailing, and health care sectors were the largest detractors from relative performance over the reporting period. In all three, stock selection was the principal factor that held back relative returns. Several individual securities in the technology sector hurt results including network equipment manufacturer Juniper Networks(g), flash memory storage products provider SanDisk, LED semiconductor maker Cree, Inc.(g), and publishing software company Adobe Systems(c)(g). Juniper Network's stock was under pressure due, in part, to an investigation into the company's stock options practices and lowered earnings guidance in its outlook for the second half of the 2006 year. In retailing, an overweighted position in poor-performing apparel retailer Chico's(g) was among the portfolio's top detractors. Disappointing earnings guidance and sales trends hurt the stock's performance. In the health care sector, cardiovascular medical devices maker St. Jude Medical(g), health care provider Humana, and dermatological treatment company Medicis Pharmaceutical(c) held back relative performance. Elsewhere, the portfolio's holdings in industrial automation products company Rockwell Automation and automatic card shuffling device maker Shuffle Master(c) detracted from relative returns as both stocks underperformed the benchmark. CONTRIBUTORS TO PERFORMANCE Stock selection in the energy and transportation sectors was a contributor to relative performance over the reporting period. However, no individual securities in either sector were among the portfolio's top contributors. The portfolio's underweighted position in the autos and housing sector aided relative results as the sector underperformed the benchmark over the reporting period. Elsewhere in the portfolio, billing software company Amdocs Ltd.(c), slot machine manufacturer International Game Technology, broadcast and communications firm American Tower, private student loans provider First Marblehead Corp., and networking semiconductor company PMC-Sierra(g) all contributed to relative performance. Amdocs' shares increased as the company reported stronger-than-expected earnings during the fiscal year and offered a positive outlook for 2007. In addition, the company secured a 5-year managed services deal with Vodafone Netherlands. Our positioning in blood test analysis systems maker Immucor(c), casino resorts operator MGM Grand(g), apparel retailer Phillips-Van Heusen Corp.(c), private-label credit card services company Alliance Data Systems, and semiconductor production equipment maker Novellus Systems also helped. RESEARCH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 10.62%, while Service Class shares provided a total return of 10.32%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 15.79% for the series' benchmark, the Standard & Poor's 500 Stock Index (S&P 500 Index). DETRACTORS FROM PERFORMANCE Stock selection in the leisure sector was the principal detractor from results relative to the benchmark. Within this sector, satellite radio service company XM Satellite Radio(c)(g) hurt results as weaker-than-expected subscriber growth and a slower rollout of new products led to lower-than-expected earnings and put pressure on its share price during the period. Security selection in the technology sector also held back performance. Several individual holdings within this sector were among the portfolio's top detractors including network equipment company Juniper Networks(g), flash memory storage products maker SanDisk, networking chip manufacturer Marvell Technology Group(c), and semiconductor giant Intel. The sources of underperformance at Marvell included a dilutive acquisition, a stock options backdating investigation, and disappointing second and third quarter results. The basic materials sector was also a negative factor in relative returns as several individual securities weighed on performance. These included packaging manufacturer Owens-Illinois(c) and newsprint company Abitibi- Consolidated(c)(g), which were both affected by higher energy prices. Additionally, Abitibi faced weaker demand for newsprint. Stocks in other sectors that hindered results included specialty apparel retailer Chico's(c), industrial equipment distributor W.W. Grainger, and home products retailer Williams-Sonoma(c)(g). CONTRIBUTORS TO PERFORMANCE The consumer staples sector was the largest contributor to relative performance. No individual holdings within this sector were among the portfolio's top contributors. Security selection in the special products and services and the industrial goods and services sectors helped relative results. Within industrial goods and services, defense contractor Lockheed Martin was a strong performer as shares gained on strong revenue growth, improved margins and key contract awards over the period. Not owning stock in industrial conglomerate General Electric also helped as the stock's return lagged that of the benchmark. Elsewhere, our positions in discount department store Kohl's(g), investment banking firm Goldman Sachs, enterprise software company Oracle(g), cable and wireless services provider Rogers Communications(c), and electric utility company FPL Group boosted relative returns. Avoiding online information portal Yahoo!, a poor-performing benchmark constituent, also benefited results. During the reporting period, 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. TOTAL RETURN SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 12.22%, while Service Class shares provided a total return of 11.91%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 15.79% for the series' benchmark, the Standard & Poor's 500 Stock Index (S&P 500 Index). The series' other benchmark, the Lehman Brothers U.S. Aggregate Bond Index (Lehman Index), had a total return of 4.33%. DETRACTORS FROM PERFORMANCE Within the equity portion of the portfolio, stock selection in the basic materials and energy sectors detracted from performance relative to the S&P 500 Index. In basic materials, packaging manufacturer Owens-Illinois(c) and newsprint maker Bowater(c) were among the portfolio's top detractors. The profitability of both companies was negatively affected by higher energy prices. Additionally, Bowater faced weaker demand for newsprint. In energy, our underweighted position in integrated oil and gas company Exxon Mobil held back relative returns. Elsewhere, telecommunications equipment manufacturer Nortel Networks(c), wireless service provider Sprint Nextel, insurance company Conseco(c), and home improvement products maker Masco dampened results. We believe Nortel's delay in filing the 2005 annual reports and restatement of certain prior period results, along with weaker-than-expected fundamentals and management's inability to turn around the business, contributed to the decline of the company's stock price. Shares of Sprint Nextel struggled after the company lowered its wireless subscriber guidance for 2006. Not holding communications service provider BellSouth also detracted from relative returns as this stock outperformed the S&P 500 Index. The cash position in the equity portion of the portfolio 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. Within the fixed income portion of the portfolio, several Treasury securities and long-maturity corporate issues held back returns relative to the Lehman Index. CONTRIBUTORS TO PERFORMANCE Within the equity portion of the portfolio, the health care, financial services, and retailing sectors were the principal contributors to performance relative to the S&P 500 Index. Stock selection was the primary factor in the strong relative performance in the health care sector. This was reinforced by underweighting this otherwise weak-performing sector. Pharmaceutical company Merck was among the portfolio's top contributors. Merck rebounded after struggling with the recall of its pain medication Vioxx. Shares of Merck also benefited from the company's cost cutting efforts and solid growth in several key products. Our underweighting of benchmark constituent UnitedHealth Group also helped as this stock's performance trailed that of the benchmark. The strong showing in the financial services and retailing sectors also resulted from security selection. PNC Financial Services Group and office products retailer OfficeMax were among the largest contributors to relative returns. In other sectors, defense contractor Lockheed Martin was a top performer as shares gained on strong revenue growth, improved margins and key contract awards over the period. Other individual stocks that contributed to results included electric utility company FPL Group, telecommunications services provider Verizon Communications, and agricultural equipment manufacturer Deere & Co. Underweighting or avoiding several poor-performing benchmark constituents, such as semiconductor company Intel and online information portal Yahoo!, further strengthened relative performance. Within the fixed income portion of the portfolio, our overweighted positions in "BBB" rated(s) securities and our small exposure to "BB" rated bonds added to performance relative to the Lehman Index (the Lehman Index does not include bonds rated lower than "BBB"). While we do not generally position the portfolio for changes in interest rates, the portfolio's short duration(d) stance boosted results as interest rates rose over the reporting period. The portfolio's yield advantage and mortgage convexity positioning (exposure to interest rate volatility) were also positive factors in relative returns. UTILITIES SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 32.35%, while Service Class shares provided a total return of 31.96%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 20.99% 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 performance for the period. Our positions in electric generators International Power(c) (U.K.) and RWE(c) (Germany) were among the portfolio's top contributors. Both companies benefited from an increasingly higher pricing environment for power in Europe. Additionally, not owning electric utility provider Southern Company, and underweighting TXU. Public Service Enterprise Group, and Dominion Resources, aided relative performance as the returns of all four stocks lagged overall benchmark returns. Several holdings within the telephone services industry, which is not represented in the benchmark, boosted relative performance over the period. These included communications companies Telenor(c) (Norway) and AT&T(c). Elsewhere, Latin American wireless communications company America Movil(c) and cable services provider Comcast(c) were notable strong-performing holdings. 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 During the reporting period, wireless service providers Sprint Nextel(c) was the top detractor from relative results. Shares of Sprint Nextel struggled after the company lowered its wireless subscriber guidance for 2006. Although overall stock selection in the electric power industry contributed to relative returns, not owning PG&E and underweighting strong-performing benchmark constituents, Entergy and Allegheny Energy(g), detracted from 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. (c) Security is not a benchmark constituent. (d) Duration is a measure of how much a bond's price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a bond with a 5-year duration is likely to lose about 5.00% of its value. (g) Security was not held in the portfolio at period end. (s) Bonds rated "BBB", "Baa", or higher are considered investment grade; bonds rated "BB", "Ba", or below are considered non-investment grade. The primary source for bond quality ratings is Moody's Investors Service. If not available, ratings by Standard & Poor's are used, else ratings by Fitch, Inc. For securities which are not rated by any of the three agencies, the security is considered Not Rated.

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 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 such subsidies and waivers the series' performance results would be less favorable. Please see the prospectus for complete 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. EXPENSE TABLES SERIES EXPENSES BORNE BY THE CONTRACT HOLDERS DURING THE PERIOD, JULY 1, 2006 THROUGH DECEMBER 31, 2006 As a contract holder of each series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. The examples are intended to help you understand your ongoing costs (in dollars) of investing in each series and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period, July 1, 2006 through December 31, 2006. 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 each series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each 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 each 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 each series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in each 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 each 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 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 insurance companies 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 reported that day, equity securities are generally valued at the last quoted daily bid quotation 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 or composite bid 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 60 days or less may be valued at amortized cost, which approximates market value. Forward foreign currency contracts are generally valued at the mean of bid and asked prices for the time period interpolated from rates reported by an independent pricing service for proximate time periods. 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 at a broker-dealer bid quotation. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates reported by an independent pricing service. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the series' investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the series' valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments. These investments are generally valued at fair value based on information from independent pricing services. In addition, investments may be valued at fair value if the adviser determines that an investment's value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the series' net asset value, or after the halting of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. Events that occur on a frequent basis after foreign markets close (such as developments in foreign markets and significant movements in the U.S. markets) and prior to the determination of the series' net asset value may be deemed to have a material affect on the value of securities traded in foreign markets. Accordingly, the series' foreign equity securities may often be valued at fair value. The adviser may rely on independent pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the series' net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine the series' net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to each series, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in each series' financial statements. 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"), 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 the 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. Income from securities lending is included in interest income on the Statements of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. Indemnifications - Under each series' organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the series. Additionally, in the normal course of business, each series enters into agreements with service providers that may contain indemnification clauses. Each series' maximum exposure under these agreements is unknown as this would involve future claims that may be made against the series that have not yet occurred. 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 when 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 Statement 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. These amounts, for the year ended December 31, 2006, are shown as a reduction of total expenses on the Statements of Operations. Tax Matters and Distributions - Each series intends to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable income, including realized capital gains. 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 U.S. 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 overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Book/tax differences primarily relate to net operating losses, amortization and accretion of debt securities, passive foreign investment companies, wash sale loss deferrals, foreign currency transactions, and foreign taxes. The tax character of distributions declared to shareholders is as follows: CAPITAL MASSACHUSETTS APPRECIATION SERIES EMERGING GROWTH SERIES GLOBAL GROWTH SERIES INVESTORS TRUST SERIES ------------------------ ------------------------ -------------------------- ---------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) ................. $1,174,123 $4,352,922 $ -- $ -- $872,242 $764,349 $8,569,963 $10,690,035 ========== ========== ===== ===== ======== ======== ========== =========== MID CAP GROWTH SERIES RESEARCH SERIES TOTAL RETURN SERIES UTILITIES SERIES ------------------------ ------------------------ -------------------------- ---------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 - ----------------------------------------------------------------------------------------------------------------------------------- Ordinary income (including any short-term capital gains) .................. $ -- $ -- $2,312,500 $2,354,184 $ 68,720,551 $ 54,343,213 $11,986,415 $3,641,287 Long-term capital gain .... -- -- -- -- 69,829,820 53,279,570 -- -- ----- ----- ---------- ---------- ------------ ------------ ----------- ---------- Total distributions ....... $ -- $ -- $2,312,500 $2,354,184 $138,550,371 $107,622,783 $11,986,415 $3,641,287 ===== ===== ========== ========== ============ ============ =========== ========== The federal tax cost and the tax basis components of distributable earnings were as follows: CAPITAL EMERGING GLOBAL MASSACHUSETTS APPRECIATION GROWTH GROWTH INVESTORS TRUST AS OF 12/31/06 SERIES SERIES SERIES SERIES - --------------------------------------------------------------------------------------------------------------------------------- Cost of investments .................................... $520,984,953 $297,256,863 $153,541,299 $999,311,372 ------------ ------------ ------------ ------------ Gross appreciation ..................................... $ 55,389,368 $ 40,155,604 $ 27,679,434 $192,029,714 Gross depreciation .....................................

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the "Interpretation") was issued, and is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management is evaluating the application of the Interpretation to each series, and has not at this time determined the impact, if any, resulting from the adoption of this Interpretation on each series' financial statements. 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 management and related administrative services and facilities to the series. 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: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.70% of average daily net assets in excess of $500 million. Effective September 1, 2006, the investment adviser has agreed in writing to reduce its management fee to 0.65% of average daily net assets in excess of $2.5 billion. This written agreement will continue through August 31, 2007, unless changed or rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. 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 total annual 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 incurred for the year ended December 31, 2006 were equivalent to an annual effective rate of each series' average daily net assets as follows. In addition, the expense limitations incurred for the year ended December 31, 2006 were as follows: EFFECTIVE INITIAL CLASS SERVICE CLASS MANAGEMENT EXPENSE EXPENSE FEES LIMITATION LIMITATION - -------------------------------------------------------------------------------- Capital Appreciation Series .......... 0.75% 1.00%(a) 1.25%(a) Emerging Growth Series ............... 0.74% N/A N/A Global Growth Series ................. 0.90% N/A N/A Massachusetts Investors Trust Series . 0.55% 1.00%(a) 1.25%(a) Mid Cap Growth Series ................ 0.75% 0.95%(b) 1.20%(b) Research Series ...................... 0.74% N/A N/A Total Return Series .................. 0.65% 1.00%(a) 1.25%(a) Utilities Series ..................... 0.73% N/A N/A (a) MFS' agreement to limit the series' operating expenses, exclusive of certain other fees and expenses, to 1.25% of the series' average daily net assets is contained in the investment advisory agreement between MFS and the series and may not be rescinded without shareholder approval. MFS' agreement to limit the series' operating expenses, exclusive of certain other fees and expenses, to 1.00% of the series' average daily net assets attributable to Initial Class shares may be changed or rescinded at any time by MFS. (b) This written agreement became effective on September 1, 2006 and will continue through August 31, 2007 unless changed or rescinded by the series' Board of Trustees. For the year ended December 31, 2006, this reduction amounted to $16,972 for Mid Cap Growth Series and is reflected as a reduction of total expenses in the Statements of Operations. For the year ended December 31, 2006, the actual operating expenses for Capital Appreciation Series, Massachusetts Investors Trust Series, and Total Return Series did not exceed the limit and therefore, the investment adviser did not pay any portion of these series' expenses. The investment adviser reimbursed the Global Growth Series $6,221 for a trade correction. This amount is included in the realized loss on investment transactions on the Statements of Operations. 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. Under an administrative services agreement, each series partially reimburses MFS the costs incurred to provide these services. Prior to June 1, 2006, each series was allocated a portion of these administrative costs based on its size and relative average net assets. Effective June 1, 2006, each series is charged an annual fixed amount of $10,000 plus a fee based on calendar year average net assets. The administrative services fee incurred for the year ended December 31, 2006 was equivalent to an annual effective rate of each series' average daily net assets as follows: PERCENT OF AVERAGE DAILY NET ASSETS ---------------------------------------------------------------- Capital Appreciation Series ..................... 0.0241% Emerging Growth Series .......................... 0.0243% Global Growth Series ............................ 0.0246% Massachusetts Investors Trust Series ............ 0.0237% Mid Cap Growth Series ........................... 0.0243% Research Series ................................. 0.0244% Total Return Series ............................. 0.0223% Utilities Series ................................ 0.0247% 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 or officers of the series who are also officers of the investment adviser, all of whom receive remuneration for their services to the series from MFS. Certain officers and trustees of the series are officers or directors of MFS, MFD, and MFSC. Other - These series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO.

In addition, each series and other funds managed by MFS have established uncommitted borrowing arrangements with certain banks. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, generally at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. For the year ended December 31, 2006, each series' commitment fee and interest expense were as follows and are included in miscellaneous expense on the Statements of Operations: COMMITMENT INTEREST FEE EXPENSE ---------------------------------------------------------------- Capital Appreciation Series ......... $ 5,276 $13,184 Emerging Growth Series .............. 2,919 -- Global Growth Series ................ 1,339 7,283 Massachusetts Investors Trust Series 9,305 -- Mid Cap Growth Series ............... 878 -- Research Series ..................... 3,079 2,546 Total Return Series ................. 17,671 1,847 Utilities Series .................... 3,339 -- (7) ACQUISITIONS On April 25, 2005, the Capital Appreciation Series acquired all of the assets and liabilities of Managed Sectors Series. The acquisition was accomplished by a tax-free exchange of 6,727,116 shares of the Capital Appreciation Series for all of the assets and liabilities of Managed Sectors Series. The Managed Sectors Series net assets on that date were $121,536,218, including $10,518,687 of unrealized appreciation, $155,623 of accumulated net investment loss, and $199,387,276 of accumulated net realized loss on investments and foreign currency transactions. These assets were combined with those of the series. The aggregate net assets of the Capital Appreciation Series after the acquisition were $743,705,558. 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, 2006, 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, 2006, 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, 2006, 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.

MFS/SUN LIFE SERIES TRUST 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 2006 ("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 of the Series 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, 2005, 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' conclusions as to the continuation of the investment advisory agreements were 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 the factors that contributed thereto and 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 other comparable 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 discussed with MFS any adjustments necessary for the shareholders' benefits. 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 parent, 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' policy not to use "soft dollars" generated by fund 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, 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, 2006. CAPITAL APPRECIATION SERIES The Trustees noted the performance of the Series' Initial Class shares was in the 5th quintile relative to the other funds in the Lipper performance universe for the one-year period (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Series was in the 4th quintile for the three-year period and the 5th quintile for the five-year period ended December 31, 2005, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS and MFS' explanation of steps taken to improve 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. In addition, the Trustees considered that MFS observes a total expense limitation for the Series. The Trustees concluded that the fees were reasonable in light of the nature and quality of services provided.

The U.S. stock market, as one notable example, posted strong gains as the Dow Jones Industrial Average hit record highs and the Standard & Poor's 500 Stock Index rose to levels not seen since 2000. While investors were undoubtedly encouraged by these positive developments, we think it is important to maintain the proper perspective on what appears to be happening with the world's financial markets. Around the globe, economies seem to have reached a state of equilibrium. Both stock and bond markets have simply been less volatile than they were in years past. While there are many factors behind the low levels of volatility, one of the key reasons is that the U.S. Federal Reserve Board and other central banks around the world seem to have found the right formula for simultaneously promoting economic growth and keeping inflation under control. This new, calmer state of affairs is no doubt welcomed by many investors, but with less volatility, the possibilities for earning exceptional returns also diminish. Investors may have to lower their expectations about what are reasonable returns from the markets. Those still looking for the types of returns they had been accustomed to in the past may have to work much harder to seek out those opportunities and perhaps also accept more risk than they customarily did. In any market climate, even in a relatively benign one, we think investors are still best served by spreading their holdings across a variety of investments that will give them exposure to a range of market opportunities and varying levels of risk. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) February 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed. MANAGEMENT REVIEWS CAPITAL OPPORTUNITIES SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 14.32%, while Service Class shares provided a total return of 14.02%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 15.79% for the series' benchmark, the Standard & Poor's 500 Stock Index. DETRACTORS FROM PERFORMANCE Relative to the benchmark, health care, utilities and communications, and leisure were the portfolio's weakest-contributing sectors. In health care, a combination of stock selection and an overweighted position hurt relative performance. Our positioning in medical device maker Advanced Medical Optics(c) was a factor in these disappointing results. Advanced Medical Optics struggled after the company lowered its earnings guidance for 2007. Management cited a slowdown in laser vision correction procedures and a slower-than-expected uptake of its multifocal intraocular lenses, especially in Europe, as reasons for its dampened outlook. In the utilities and communications sector, not owning benchmark constituent AT&T detracted from relative performance as this stock posted strong gains over the reporting period. In the leisure sector, it was a combination of stock selection and an underweighted position that dampened investment results. No individual securities in this sector were among the portfolio's top detractors. Stocks in other sectors that had a negative impact on relative performance included poor-performing multimedia image provider Getty Images(c), package manufacturer Owens-Illinois(c), direct-sale computer vendor Dell, auto parts retailer Advance Auto Parts(c), online information portal Yahoo!, and global telecommunications equipment maker Nortel Networks(c)(g). Getty Images' stock fell due to a slowing image market that led to a depressed revenue trend. 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 Retailing, consumer staples, and technology were the portfolio's top contributing sectors to relative performance over the period. In all three sectors, stock selection was the key factor. In retailing, the portfolio's positioning in strong-performing specialty used- car dealer CarMax(c) had a positive impact on relative returns. CarMax's stock price appreciated due to strong store traffic, particularly in the company's new Atlanta buying center. Our holdings in discount department store Kohl's(g) also helped as this stock outperformed the benchmark. In the consumer staples sector, our positioning in global food company Nestle S.A.(c) was beneficial to relative results. In technology, strong contributors included network equipment company Cisco Systems and enterprise software giant Oracle. Elsewhere, our holdings in billing software company Amdocs Ltd.(c)(g), media conglomerate Walt Disney(g), and property and casualty insurer The St. Paul Travelers Cos. aided relative results. Not holding weak-performing benchmark constituents, General Electric and UnitedHealth Group, also helped. During the reporting period, the portfolio's currency exposure contributed 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. CORE EQUITY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 13.74%, while Service Class shares provided a total return of 13.44%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 15.72% for the series' benchmark, the Russell 3000 Index. The Russell 3000 Index became the series' benchmark effective July 20, 2006. For the period December 31, 2005 to July 19, 2006, the series' benchmark was the Standard & Poor's 500 Stock Index (S&P 500 Index). The return for the S&P 500 Index for the twelve months ended December 31, 2006 was 15.79%. DETRACTORS FROM PERFORMANCE Stock selection in the leisure sector was the greatest detractor from relative performance over the period. Within this sector, satellite radio service company XM Satellite Radio(g) hurt results. XM Satellite Radio's share price was under pressure due to weaker-than-expected subscriber growth and a slower rollout of new products. Security selection in the utilities and communications sector also held back results. Our positioning in wireless services provider Sprint Nextel(g) was a top detractor. Shares of Sprint Nextel struggled after the company lowered its wireless subscriber guidance for 2006. In addition, we believe that its merger integration with Nextel has disappointed investors. Not holding strong- performing telecommunications services provider BellSouth also hindered relative performance. In the financial services sector, stock selection had a negative impact on relative returns. Student loans provider SLM Corp. (Sallie Mae) and investment management firm Legg Mason were among the portfolio's largest detractors. Legg Mason's shares suffered after the company continued to miss their quarterly earnings targets as expenses were greater than anticipated. Individual stocks in other sectors that detracted from relative results included flash memory storage products maker SanDisk, managed health services company Health Net(g), newsprint manufacturer Abitibi-Consolidated(c)(g), integrated logistics company UTi Worldwide(c), and pharmaceuticals manufacturer Eli Lilly. CONTRIBUTORS TO PERFORMANCE Security selection in the energy, health care, and consumer staples sectors benefited relative results. Within energy, our overweighted position in integrated oil and gas company Hess was a top contributor. In health care, health insurance and Medicare/Medicaid provider UnitedHealth Group was another positive contributor. Avoiding United Healthcare for a majority of the period and buying our position opportunistically had a positive effect on our relative results. No individual stocks in the consumer staples sector were among the portfolio's top contributors. An underweighted position in the special products and services sector also helped relative performance. No individual securities within this sector were among the portfolio's top contributors. Stocks in other sectors that boosted relative results included diversified technology company Corning(g), enterprise software provider Salesforce.com, defense contractor Lockheed Martin, and agrichemical products company Monsanto. Elsewhere, wireless services provider Rogers Communications(c), business intelligence software company MicroStrategy(g), sporting goods maker NIKE, and computer products and services provider Hewlett-Packard benefited results. INTERNATIONAL GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 26.04% while the Service Class shares provided a total return of 25.75%. These returns do not reflect any applicable surrender or contract charges and compare with a return of 22.69% for the series' benchmark, the MSCI EAFE Growth Index. CONTRIBUTORS TO PERFORMANCE Stock selection in the retailing sector was a positive factor in the portfolio's relative performance led by our overweighted position in Hong Kong-based consumer products export trading and logistics company Li & Fung. Stock selection in the utilities and communications sector also boosted results. Wireless communications company China Mobile(c) (Hong Kong), telecommunications company Telenor (Norway), electric utility company Iberdrola(g) (Spain) were among the portfolio's top contributors. The stock price of Iberdrola benefited from merger speculation taking place in the European utilities industry. Stock selection and, to a lesser extent, our overweighted positioning in the financial services sector had a positive impact on results. Financial services firm Bank of Cyprus(c), banking firms Raiffeisen International Bank Holding (Austria) and Bank Rakyat Indonesia(c)(g), bolstered relative returns. Avoiding weak-performing diversified financial services firm Mitsubishi UFJ Financial Group (Japan) also helped. Stock selection in the energy sector also strengthened relative returns, although no individual stocks within this sector were among the portfolio's top contributors. Elsewhere, biopharmaceutical company Actelion(c) (Switzerland) was the largest contributor to relative performance over the period. The company's stock price climbed significantly due to the accelerating growth of its main drug, Tracleer (a treatment for pulmonary arterial hypertension) and the weakening competition facing this drug. Avoiding poor-performing technology investment firm Softbank (Japan) also aided results. DETRACTORS FROM PERFORMANCE Consumer finance firms, AEON Credit Service (Japan) and Aiful(c)(g) (Japan), were among the portfolio's most significant individual detractors. Aiful struggled during the period in an increasingly difficult regulatory, business, and media environment for consumer finance companies. Our positions in microchip and electronics manufacturer Samsung Electronics(c) (South Korea) and industrial adhesive tapes maker Nitto Denko (Japan) also dampened results. During the reporting period, 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. 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. MASSACHUSETTS INVESTORS GROWTH STOCK SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 7.67%, 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 9.07% for the series' benchmark, the Russell 1000 Growth Index. DETRACTORS FROM PERFORMANCE Stock selection and our positioning in the technology sector held back performance relative to the benchmark. Within this sector, networking chip maker Marvell Technology Group(c), data storage systems provider EMC Corp., and flash memory products maker SanDisk were among the portfolio's top detracting holdings. Weakness in Marvell's stock was due, in part, to a dilutive acquisition, a stock option backdating investigation, and disappointing second and third quarter operating results. EMC's stock was under pressure after the company pre-announced weak second quarter results. Customer demand for its next generation high end storage product was under- estimated, causing shipping delays. Stock selection in the leisure sector, driven by our holding in Carnival Cruise Line(c)(g), held back relative performance. Softening demand for Carnival's Caribbean cruises, primarily in the low and mid level brands, combined with rising fuel costs, caused Carnival to reduce its 2006 earnings guidance early in the year. Not holding strong-performing cable company Comcast also detracted from results. A combination of stock selection and an underweighted position in the strong- performing consumer staples sector hurt relative returns. No individual holdings within this sector were among the portfolio's top detractors. There were a number of stocks in the health care sector that hurt relative performance. Biotechnology firm Genzyme, medical device maker Advanced Medical Optics, and cardiovascular medical devices manufacturer St. Jude Medical were among the top detractors. Shares of Genzyme declined after the company missed their first quarter earnings target and reported slightly lower sales of drugs, Fabrazyme and Synvisc. Higher operating expenses also held back the stock's performance. Advanced Medical Optics struggled after the company lowered its earnings guidance for 2007. Management cited a slowdown in laser vision correction procedures and a slower-than-expected uptake of its multifocal intraocular lenses, especially in Europe, as reasons for its dampened outlook. In retailing, home products retailer Williams-Sonoma and specialty apparel retailer Chico's(g) were among the top detractors. At Williams-Sonoma, strong sales from the company's emerging brands were unable to offset weaker sales from their core brands. Weakness in the Chico's brand and heavy investments in its younger concepts pressured the company's results throughout the period. CONTRIBUTORS TO PERFORMANCE Stock selection and an underweighted position in the energy sector helped relative performance, although no individual names within this sector were among the top contributors to relative results. Stock selection in the basic materials and special products and services sectors also aided relative returns. Within special products and services, billing software company Amdocs Ltd.(c) was a strong performer relative to the benchmark. Amdocs continued to benefit from two secular trends within the communications sector: telecommunications carrier consolidation and the convergence of wireless, wireline, and cable. No individual holdings within the basic materials sector were among the top contributors. The portfolio's underweighted position in transportation, a sector that lagged the overall benchmark, also benefited relative results. Elsewhere, network equipment company Cisco Systems and wireless communications provider America Movil(c) were strong contributors over the period. Cisco's shares rose as the company reported strong earnings. In the latter half of the period, the company gave better-than-expected fiscal second quarter guidance and reiterated their confidence that the company's full year earnings would be at the high end of their projected range. America Movil gained on continued strength in subscriber growth and stable ARPUs (average revenue per user). Casino resorts operator Las Vegas Sands and slot machine maker International Game Technology(g) contributed to results. Other stocks that boosted relative returns included biotechnology companies Celgene and Gilead Sciences(g), wireless equipment company QUALCOMM, and investment banking firm Morgan Stanley. During the reporting period, 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. MID CAP VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 11.30%, while Service Class shares provided a total return of 11.01%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 20.22% for the series' benchmark, the Russell Midcap Value Index. DETRACTORS FROM PERFORMANCE Stock selection in the basic materials sector was the primary detractor from relative performance over the period. Individual holdings within this sector that hurt results included package manufacturer Owens-Illinois(g), paper products company Smurfit-Stone Container, and newsprint maker Bowater(c)(g). Owens-Illinois was hurt by higher energy costs and disappointing results from its operational improvement initiatives. Bowater was also affected by energy costs as well as weaker demand for newsprint. A combination of security selection and our overweighted position in the technology sector detracted from relative returns. Within this sector, global telecommunications equipment company Nortel Networks(c)(g) and flash memory storage products maker SanDisk were among the portfolio's top relative detractors. Stock selection in the health care sector also detracted from results, although no stocks within this sector were among the top detractors. Other stocks that held back results included retail real estate operator Mills Corporation(c)(g), homebuilder D.R. Horton, and newspaper publisher Lee Enterprises. Not owning strong-performing benchmark constituent Archer Daniels Midland (ADM), an agricultural production company, also dampened relative returns. CONTRIBUTORS TO PERFORMANCE Security selection in the utilities and communications sector was the principal contributor to relative results. Within this sector, our position in local communications service provider Embarq, a recent spin-off of Sprint Nextel, contributed to performance. Driven by increases in high speed Internet revenues, results at Embarq exceeded market expectations. Natural gas company Williams Companies and electric power suppliers, American Electric Power and Northeast Utilities, also helped. Stock selection in the energy sector aided results, with drill-rig operator GlobalSantaFe(c) and oil and gas explorer Riata Energy(c)(g) among the portfolio's top relative contributors. Elsewhere, the portfolio benefited from our positions in specialty mattress maker Tempur-Pedic International(c), casino resorts operator MGM MIRAGE(c), and real estate investment trust Equity Office Properties. NEW DISCOVERY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 13.17%, while Service Class shares provided a total return of 12.90%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 13.35% for the series' benchmark, the Russell 2000 Growth Index. DETRACTORS FROM PERFORMANCE A combination of stock selection and an overweighted position in the health care sector held back relative performance. Overweighted positions in medical equipment company Aspect Medical Systems and medical device makers, Cyberonics and Thoratec, led to disappointing results as all three stocks underperformed the benchmark. Aspect Medical has penetrated close to 50% of operating rooms in the U.S. with their hospital room monitoring system (BIS), and sales growth of monitors has been strong. Nevertheless, the stock was under pressure because of concerns about the slowing of growth in the company's sensors product. Cyberonics' stock price declined after the company lowered revenue guidance for their first fiscal quarter of 2007 and delayed expectations for profitability. Investigations into the company's stock options practices led to a delay in the company's SEC filing and uncertainty as to whether NASDAQ would delist its stock. Stock selection in the consumer staples sector and a combination of stock selection and an underweighted position in the basic materials sector also dampened investment results. No individual securities in either of these sectors were among the portfolio's top detractors. Stocks in other sectors that hurt relative returns included LED semiconductor maker Cree, Inc.(c), casual dining restaurant Red Robin Gourmet Burgers, game software developer Take-Two Interactive Software(g), automatic card shuffling device maker Shuffle Master, vision systems producer Cognex(g), retail chain operator Hot Topic(g), and flash memory disk maker Msystems(c)(g). CONTRIBUTORS TO PERFORMANCE Stock selection in the special products and services sector contributed to the portfolio's relative performance over the reporting period. Our positioning in managed network services provider Equinix and computer software company Open Solutions(g) strengthened relative results. Equinix's stock price benefited from strong demand and its ability to increase pricing on its products and services. Stock selection also helped in the technology sector. Our holdings in data recording products provider NICE Systems(c) and speech and imaging software firm Nuance Communications aided results as both stocks delivered strong performance. The portfolio's underweighted position in the relatively weak autos and housing sector benefited relative returns. No individual securities in this sector were among the portfolio's top contributors. Elsewhere, the portfolio's positioning in permanent birth control device maker Conceptus, global communications and information services company Level 3 Communications(c), infrastructure services providers InfraSource Services and Quanta Services, quick service eatery Chipotle Mexican Grill, and retailer CarMax contributed to relative performance. RESEARCH INTERNATIONAL SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 27.47%, while the Service Class shares provided a total return of 27.25%. These returns do not reflect any applicable surrender or contract charges and compare with a return of 26.86% for the series' benchmark, the MSCI EAFE Index. CONTRIBUTORS TO PERFORMANCE Stock selection in the energy sector boosted performance relative to the benchmark. Integrated oil company LUKOIL(c)(g) (Russia) and steel tubes manufacturer Vallourec (France) were among the top contributors in this sector. Avoiding integrated oil company BP Amoco (UK) also helped as this company underperformed the benchmark. Stock selection in the utilities and communications sector enhanced relative performance. Strong performers in this sector included telecommunications company Telenor (Norway), energy and utility operations company SUEZ (France), and electric utility company Iberdrola(g) (Spain). The stock price of Iberdrola benefited from merger speculation in the European utilities industry. Stock selection in the basic materials sector also had a positive effect on the portfolio's relative returns. This was led by steel producer Arcelor Mittal(c)(g) (Luxembourg) and agrochemical company Sygenta (Switzerland). Stocks in other sectors that contributed to results included biopharmaceutical company Actelion(c) (Switzerland) and video game console maker Nintendo (Japan). Actelion was the largest contributor to the portfolio's relative performance over the period. The company's stock price climbed significantly due to the accelerating growth of its main drug, Tracleer (a treatment for pulmonary arterial hypertension), and the weakening competition facing this drug. DETRACTORS FROM PERFORMANCE Stock selection in the financial services sector was the principal factor holding back relative performance. Consumer finance firms Aiful(g) (Japan), AEON Credit Services (Japan), and Takefuji(g) (Japan), real estate investment consulting firm K.K. Davinci Advisors(g) (Japan), and diversified financial services firm Mitsubishi UFJ Financial Group (Japan) were among the portfolio's largest detractors. Aiful and Takefuji struggled during the period in an increasingly difficult regulatory, business, and media environment for consumer finance companies. Elsewhere, microchip and electronics manufacturer Samsung Electronics(c) (South Korea), basic chemicals, resin, and plastics maker Kaneka(g) (Japan), and electronics retailer Yamada Denki(g) (Japan) detracted from results. Shares of Samsung suffered as a result of disappointing earnings in first half of the period. Our overweighted position in pharmaceutical company GlaxoSmithKline (UK) also hurt as this stock underperformed the benchmark. During the reporting period, 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. 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. STRATEGIC GROWTH SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 6.58%, while Service Class shares provided a total return of 6.37%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 9.07% for the series' benchmark, the Russell 1000 Growth Index. DETRACTORS FROM PERFORMANCE A combination of stock selection and an overweighted position in the technology sector held back relative performance. Top detractors included network equipment manufacturer Juniper Networks, networking chip maker Marvell Technology Group(c), online information portal Yahoo!, flash memory storage products company SanDisk, and global telecommunications equipment company Nortel Networks(c)(g). Juniper Networks' stock was under pressure due, in part, to an investigation into the company's stock options practices and lowered earnings guidance in its outlook for the second half of the 2006 year. The source of disappointing results at Marvell included a dilutive acquisition, a stock options backdating investigation, and disappointing second and third quarter operating results. We believe that Nortel's lowered earnings guidance and general pricing pressures led to the stock's decline. A combination of stock selection and an overweighted position in the health care sector hurt relative results over the period. Cardiovascular medical device maker St. Jude Medical detracted from performance as this stock underperformed the benchmark. Advanced Medical Optics pre-announced disappointing third quarter results citing a slowdown in laser vision correction procedures, and a slower than expected uptake for multifocal lenses, specifically in Europe. Later in the year, the company was forced to recall eye care products manufactured in a plant in China due to manufacturing issues. The portfolio's underweighted position in the industrial goods and services sector was a detractor from relative performance. Strong performance from industrial automation products manufacturer Rockwell Automation was not enough to offset our underweighted position in the sector. Stocks in other sectors that hurt relative performance included online auctioneer eBay and multimedia image provider Getty Images(g). CONTRIBUTORS TO PERFORMANCE A combination of stock selection and an overweighting in the leisure sector benefited performance over the period. Casino resorts operator Las Vegas Sands was a top contributor. The firm increased earnings and revenues throughout the year due, in part, to growth in its Sands Macau operations located in China. Stock selection and an overweighted position in the utilities and communications sector were the principal factors in sustaining the portfolio's relative performance. Latin American wireless communications firm American Movil(c) and broadcast and communications tower management firm American Tower were among the portfolio's top contributors. Stock selection in the retailing sector was also an area of strength during the period, although no individual securities within this sector were among the top contributors. Other significant contributors to relative performance included biotechnology companies Celgene and Gilead Sciences along with our underweighted position in poor-performing chip giant Intel. STRATEGIC VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 14.16%, while Service Class shares provided a total return of 13.92%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 22.25% for the series' benchmark, the Russell 1000 Value Index. DETRACTORS FROM PERFORMANCE A combination of stock selection and an overweighted position in the technology sector hurt relative performance. In this sector, global telecommunications equipment company Nortel Networks(c) was a top detractor. We believe that Nortel's lowered earnings guidance and general pricing pressures led to the stock's decline. Owning poor-performing direct-sale computer vendor Dell(c)(g) and software developer Compuware also dampened relative results. Stock selection in the basic materials sector held back relative performance. Packaging manufacturer Owens-Illinois and newsprint maker Bowater(c) were among the portfolio's top detractors. Both stocks were affected by higher energy costs. Owens-Illinois was also hurt by the company's disappointing results from its operational improvement initiatives. Bowater's stock was under pressure due to weaker demand for newsprint. Stock selection and, to a lesser extent, an underweighting in the energy sector led to disappointing results. Avoiding Exxon Mobil detracted from results as the stock outperformed the benchmark over the period. Stocks in other sectors that detracted from relative returns included wireless provider Sprint Nextel(g), financial services firm Conseco, and home improvement products maker Masco. Sprint Nextel's share price was down due to weaker-than-expected growth in subscribers and concerns regarding the quality of the firm's customer base. CONTRIBUTORS TO PERFORMANCE Stock selection in the retailing sector contributed to the portfolio's relative performance. Office products retailer OfficeMax and retail chain operator Saks(g) were top contributors. A combination of stock selection and an underweighting in the financial services sector aided relative results. Financial services firms Bank of New York and PNC Bank benefited performance as both stocks outperformed the benchmark over the reporting period. Not holding poor-performing insurer American International Group also helped. Stock selection in the health care sector was another area of relative strength. Pharmaceutical company Merck(g) was among the portfolio's top contributors. Other stocks that contributed to relative performance included strong- performing telecommunications service provider Verizon and electric power supplier FPL Group. Toy manufacturer Mattel and enterprise software giant Oracle(c)(g) proved positive as both firms performed well over the period. TECHNOLOGY SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 21.97%, while Service Class shares provided a total return of 21.59%. These returns do not reflect any applicable contract or surrender charges and compare with a return of 8.98% for the series' benchmark, the Goldman Sachs Technology Industry Composite Index. CONTRIBUTORS TO PERFORMANCE Strong stock selection and, to a lesser extent, an overweighted position in the Internet industry were the principal factors contributing to the portfolio's relative performance. Our investments in Chinese search engine Baidu.com(c) and Chinese Internet operator Tencent Holdings(c) contributed to relative performance. On the other hand, not holding online information portal Yahoo! added to relative results as this stock underperformed the benchmark over the reporting period. Stock selection in the business services industry also aided relative performance. Strong-performing managed network services company Equinix and information technology consulting services provider Cognizant Technology Solutions were top contributors. Stock selection in the computer software industry was also a positive factor. Overweighting business intelligence software firm MicroStrategy(c)(g) aided relative results. Elsewhere, the portfolio's underweighting in weak-performing wireless communications software firm QUALCOMM(g) and not holding online auctioneer eBay also helped as both stocks underperformed the benchmark. Entertainment and games software company Capcom(c) and electronic and power supply manufacturer Delta Electronics(c)(g) were also among the portfolio's top contributors. DETRACTORS FROM PERFORMANCE Stock selection in the network and telecommunications industry detracted from performance relative to the benchmark. Global telecommunications equipment company Nortel Networks and network equipment manufacturer Juniper Networks were top detractors. Nortel's lowered earnings guidance and general pricing pressures led to the stock's decline. Juniper Networks' shares were under pressure due, in part, to an investigation into the company's stock options practices and lowered earnings guidance in its outlook for the second half of the 2006 year. The portfolio's underweighted position in the computer systems industry was a key factor in relative underperformance. Underweighting strong-performing computer products and services company Hewlett-Packard, and not holding computer company IBM, hurt performance. Vision systems Cognex(c)(g) also detracted from results. Other stocks that detracted from performance included overweighted positions in flash memory storage products company SanDisk and networking chip maker Marvell Technology Group. The sources of disappointing results at Marvell included a dilutive acquisition, a stock options backdating investigation, and disappointing second and third quarter operating results. Not holding software giant Microsoft(c) and positioning in computer software firm Filenet(g) also hurt relative results. VALUE SERIES SUMMARY OF RESULTS For the twelve months ended December 31, 2006, Initial Class shares of the series provided a total return of 20.96%, while Service Class shares provided a total return of 20.66%. These compare with a return of 22.25% for the series' benchmark, the Russell 1000 Value Index. DETRACTORS FROM PERFORMANCE Security selection in the utilities and communications sector dampened relative results during the period. Our overweighted position in weak- performing wireless provider Sprint Nextel was a primary detractor from relative performance. The stock was down due to weaker-than-expected growth in subscribers and concern about the customer base. Overweighting Dominion Resources, a transmitter and distributor of electricity and natural gas, was also a drawback as this stock underperformed the benchmark. Not owning strong- performing benchmark constituents, Bellsouth and AT&T, also detracted. Stock selection in the energy sector was another area of relative weakness. Underweighting Exxon Mobil detracted from results as the stock outperformed the Russell 1000 Value Index. Stock selection in the basic materials sector was also a detractor, although no individual securities within this sector were among the portfolio's top detractors. Elsewhere, health care company Johnson & Johnson hurt relative returns. Johnson & Johnson's share price was under pressure during the period due to concerns surrounding its pharmaceutical patent expirations and a maturation of the drug eluting stent business. Our overweighted positions in home improvement product maker Masco and railroad company Burlington Northern Santa Fe and not holding global financial services firm Morgan Stanley, also negatively affected relative returns. 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 in the financial services sector was the most positive contributor to results. A principal factor helping performance was our overweighted position in investment banking firm Goldman Sachs. During the year, Goldman Sachs completed a substantial share repurchase program and delivered earnings results that exceeded expectations. Avoiding insurer American International Group helped performance as the stock lagged the benchmark over the period. Stock selection in the industrial goods and services sector also helped performance relative to the benchmark. Our positioning in defense contractor Lockheed Martin(c) aided performance as the company continued to report quarterly results that exceeded expectations. As a result, this stock outperformed the broad benchmark. Overweighting Deere & Co. also helped as the company continued to turn in good quarterly results. Finally, avoiding General Electric stock positively affected performance as this company substantially lagged the benchmark. Stock selection in the consumer staples sector also contributed to our results. Our positioning in Archer-Daniels Midland (ADM)(g), a processor of oilseeds, corn, and wheat, performed well on the back of improving secular trends. Owning Diageo PLC(c) was another source of relative return over the period. Elsewhere, agrichemical company Syngenta(c) added to relative results as the stock outperformed over the period. Owning Cisco Systems(c) was also beneficial to performance as its shares appreciated significantly. Although the utilities and communications sector was a detractor overall, our overweighting of public utility holding company FPL Group within this sector was helpful. During the reporting period, our currency exposure was a contributor to 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 index.

Service Class shares have no sales charge and carry a 0.25% annual 12b-1 fee. Service Class share performance for all series except Mid Cap Value Series and Strategic Value Series, 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, for all series, reflect any applicable expense subsidies and waivers in effect during the periods shown; without such subsidies and waivers the series' performance results would be less favorable. Please see the prospectus for complete 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. EXPENSE TABLES SERIES EXPENSES BORNE BY THE CONTRACT HOLDERS DURING THE PERIOD, JULY 1, 2006 THROUGH DECEMBER 31, 2006 As a contract holder of each series, you incur ongoing costs, including management fees; distribution (12b-1) fees; and other series expenses. The examples are 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 examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period, July 1, 2006 through December 31, 2006. 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 each series' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each 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 each 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 each series' ongoing costs only and do not take into account the fees and expenses imposed under the variable contracts through which your investment in each 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 The financial highlights table is intended to help you understand the series' financial performance for the past 5 years. Certain information reflects financial results for a single series share.

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 insurance companies 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 reported that day, equity securities are generally valued at the last quoted daily bid quotation as reported by an independent pricing service on the market or exchange on which they are primarily traded. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker-dealer bid quotation. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates reported by an independent pricing service. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the series' investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the series' valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments. These investments are generally valued at fair value based on information from independent pricing services. In addition, investments may be valued at fair value if the adviser determines that an investment's value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the series' net asset value, or after the halting of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. Events that occur on a frequent basis after foreign markets close (such as developments in foreign markets and significant movements in the U.S. markets) and prior to the determination of the series' net asset value may be deemed to have a material affect on the value of securities traded in foreign markets. Accordingly, the series' foreign equity securities may often be valued at fair value. The adviser may rely on independent pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the series' net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine the series' net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the series, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in each series financial statements. 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 the 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. Indemnifications - Under each series' organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the series. Additionally, in the normal course of business, each series enters into agreements with service providers that may contain indemnification clauses. Each series' maximum exposure under these agreements is unknown as this would involve future claims that may be made against the series that have not yet occurred. 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 when 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 Statement 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. These amounts, for the year ended December 31, 2006, are shown as a reduction of total expenses on the Statements of Operations. Tax Matters and Distributions - Each series intends to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable income, including realized capital gains. 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 U.S. 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 overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions 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, foreign currency transactions, and foreign taxes. The tax character of distributions declared to shareholders is as follows: CAPITAL OPPORTUNITIES INTERNATIONAL GROWTH MASSACHUSETTS INVESTORS SERIES CORE EQUITY SERIES SERIES GROWTH STOCK SERIES ------------------------ ------------------------ ------------------------ ----------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 ----------- ----------- ----------- ----------- ----------- ----------- ----------- ---------- Ordinary income (including any short-term capital gains) ................... $ 978,683 $ 2,157,384 $ 523,238 $ 597,682 $ 957,105 $ 1,214,948 $ 344,988 $2,408,735 Long-term capital gain ..... -- -- -- -- 11,592,743 -- -- -- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ---------- Total distributions ........ $ 978,683 $ 2,157,384 $ 523,238 $ 597,682 $12,549,848 $ 1,214,948 $ 344,988 $2,408,735 =========== =========== =========== ========== =========== =========== =========== ========== RESEARCH INTERNATIONAL MID CAP VALUE SERIES NEW DISCOVERY SERIES SERIES STRATEGIC GROWTH SERIES ------------------------ ------------------------ ------------------------ ----------------------- 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 ----------- ----------- ----------- ----------- ----------- ----------- ----------- ---------- Ordinary income (including any short-term capital gains) ................... $ 1,728,975 $ 2,449,607 $ -- $ -- $ 4,590,713 $ 1,115,634 $ -- $ 184,439 Long-term capital gain ..... 1,357,125 412,730 -- -- 11,276,553 -- -- -- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ---------- Total distributions ........ $ 3,086,100 $ 2,862,337 $ -- $ -- $15,867,266 $ 1,115,634 $ -- $ 184,439 =========== =========== =========== =========== =========== =========== =========== ========== STRATEGIC VALUE SERIES TECHNOLOGY SERIES VALUE SERIES ------------------------ ------------------------ ------------------------ 12/31/06 12/31/05 12/31/06 12/31/05 12/31/06 12/31/05 ----------- ----------- ----------- ----------- ----------- ----------- Ordinary income (including any short-term capital gains) ................... $ 326,612 $ 598,886 $ -- $ -- $ 6,536,556 $ 6,089,141 Long-term capital gain ..... 535,561 601,688 -- -- 16,774,240 -- ----------- ----------- ----------- ----------- ----------- ----------- Total distributions ........ $ 862,173 $ 1,200,574 $ -- $ -- $23,310,796 $ 6,089,141 =========== =========== =========== =========== =========== =========== The federal tax cost and the tax basis components of distributable earnings were as follows: MASSACHUSETTS CAPITAL CORE INTERNATIONAL INVESTORS OPPORTUNITIES EQUITY GROWTH GROWTH STOCK AS OF 12/31/06 SERIES SERIES SERIES SERIES - ---------------------------------------------------------------------------------------------------------------------------------- Cost of investments ................................................ $ 192,497,713 $ 95,556,706 $ 152,462,035 $409,730,865 ------------- ------------- ------------- ------------ Gross appreciation ................................................. $ 16,916,981 $ 10,410,197 $ 36,461,328 $ 34,001,294 Gross depreciation .................................................

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the "Interpretation") was issued, and is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management is evaluating the application of the Interpretation to each series, and has not at this time determined the impact, if any, resulting from the adoption of this Interpretation on each series' financial statements. 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 management and related administrative services and facilities to the series. 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. Core Equity Series: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.65% of average daily net assets in excess of $500 million. Effective September 1, 2006, the investment adviser has agreed in writing to reduce its management fee to 0.60% of average daily net assets in excess of $2.5 billion. This written agreement will continue through August 31, 2007, unless changed or rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. International Growth 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. Massachusetts Investors Growth Stock Series: The management fee is 0.75% of average daily net assets. The investment adviser has agreed in writing to reduce its management fee to 0.70% of average daily net assets in excess of $1 billion. This written agreement may be rescinded only upon consent of the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $1 billion and therefore, the management fee was not reduced. Mid Cap Value Series: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.70% of average daily net assets in excess of $500 million. Effective September 1, 2006, this agreement was rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. New Discovery Series: The management fee is 0.90% of the first $1 billion of average daily net assets and 0.80% of average daily net assets in excess of $1 billion. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.80% in excess of $500 million. Effective September 1, 2006, the investment adviser has agreed in writing to reduce its management fee to 0.75% of average daily net assets in excess of $2.5 billion. This written agreement will continue through August 31, 2007 unless changed or rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. Research International 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. Strategic Growth Series: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.65% of average daily net assets in excess of $500 million.

This written agreement will continue through August 31, 2007 unless changed or rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. Strategic Value Series: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.65% of average daily net assets in excess of $500 million. Effective September 1, 2006, this agreement was rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. Technology Series: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.70% of average daily net assets in excess of $500 million. Effective September 1, 2006, this agreement was rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced. Value Series: 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. At the commencement of the period and until August 31, 2006, the investment adviser had agreed to reduce its management fee to 0.65% of average daily net assets in excess of $500 million. Effective September 1, 2006, this agreement was rescinded by the series' Board of Trustees. For the year ended December 31, 2006, the series' average daily net assets did not exceed $500 million and therefore, the management fee was not reduced.

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. Under an administrative services agreement, each series partially reimburses MFS the costs incurred to provide these services. Prior to June 1, 2006, each fund was allocated a portion of these administrative costs based on its size and relative average net assets. Effective June 1, 2006, each series is charged an annual fixed amount of $10,000 plus a fee based on calendar year average net assets. The administrative services fee incurred for the year ended December 31, 2006 was equivalent to an annual effective rate of each series' average daily net assets as follows: PERCENT OF AVERAGE DAILY NET ASSETS - ---------------------------------------------------------------------------- Capital Opportunities Series ............................ 0.0246% Core Equity Series ...................................... 0.0245% International Growth Series ............................. 0.0248% Massachusetts Investors Growth Stock Series ............. 0.0243% Mid Cap Value Series .................................... 0.0310% New Discovery Series .................................... 0.0247% Research International Series ........................... 0.0251% Strategic Growth Series ................................. 0.0244% Strategic Value Series .................................. 0.0695% Technology Series ....................................... 0.0352% Value Series ............................................ 0.0246% 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 or officers of the series who are also officers of the investment adviser, all of whom receive remuneration for their services to the series from MFS. Certain officers and trustees of the series are officers or directors of MFS, MFD, and MFSC. Other - These series and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds.

In addition, each series and other funds managed by MFS have established uncommitted borrowing arrangements with certain banks. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, generally at a rate equal to the Federal Reserve funds rate plus 0.35%. In addition, a commitment fee, based on the average daily, unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. For the year ended December 31, 2006, each series' commitment fee and interest expense were as follows and are included in miscellaneous expense on the Statements of Operations: COMMITMENT INTEREST FEE EXPENSE - ----------------------------------------------------------------------------- Capital Opportunities Series .................... $1,672 $ -- Core Equity Series .............................. 757 289 International Growth Series ..................... 1,249 4,614 Massachusetts Investors Growth Stock Series ..... 3,839 -- Mid Cap Value Series ............................ 213 -- New Discovery Series ............................ 2,689 3,875 Research International Series ................... 1,847 1,983 Strategic Growth Series ......................... 623 -- Strategic Value Series .......................... 82 -- Technology Series ............................... 179 -- Value Series .................................... 3,738 591 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, 2006, 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, 2006, 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, 2006, 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.

MFS/SUN LIFE SERIES TRUST RESULTS OF SHAREHOLDER MEETING (UNAUDITED) -- 12/31/06 At a special meeting of shareholders of the Technology Series, which was held on August 15, 2006, the following actions were taken: Item 1. To approve a change to the Series' sub-classification under the Investment Company Act of 1940 from a diversified company to a non-diversified company: NUMBER OF DOLLARS Affirmative ........... $17,595,735.63 Against ................ 1,790,756.31 Abstain ................ 1,061,697.75 Item 2. To approve an amendment to the Series' fundamental investment policy concerning concentration. NUMBER OF DOLLARS Affirmative ........... $17,435,948.03 Against ................ 1,941,685.55 Abstain ................ 1,070,556.11 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 2006 ("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 of the Series 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, 2005, 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' conclusions as to the continuation of the investment advisory agreements were 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 the factors that contributed thereto and 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 other comparable 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 discussed with MFS any adjustments necessary for the shareholders' benefits. 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 parent, 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' policy not to use "soft dollars" generated by fund 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, 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, 2006. CAPITAL OPPORTUNITIES SERIES The Trustees noted the performance of the Series' Initial Class shares was in the 5th quintile relative to the other funds in the Lipper performance universe for the one-year period (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Series was in the 4th quintile for the three-year period and the 5th quintile for the five-year period ended December 31, 2005, relative to the Lipper performance universe. Based on the nature and quality of services provided by MFS and MFS' explanation of recent steps taken to improve 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 was at the median and 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.

Related Entities. (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, analysis of certain portfolio holdings versus investment styles, review of internal controls and review of Rule 38a-1 compliance program. 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 in each period between 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 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.

There were no material changes to the procedures by which shareholders may send recommendations to the Board for nominees to the Registrant's Board since the Registrant last provided disclosure as to such procedures in response to the requirements of Item 407(c)(2)(iv) of Regulation S-K (as required by Item 22(b)(15) of Schedule 14A), or this Item. ITEM 11. CONTROLS AND PROCEDURES.

(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 of the period covered by the report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
