LETTER FROM THE CEO OF MFS

DEAR CONTRACT OWNERS:

The year 2006 proved to be a very good one for many of the world's financial
markets. 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

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.

(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.
(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which
    have been pre-refunded or pre-paid to an earlier date or which have a
    mandatory put date prior to the stated maturity. The average life shown
    takes into account these earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. For those portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holdings in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in the "AAA"-rating
    category. Percentages are based on the total market value of investments as
    of 12/31/06.

Percentages are based on net assets as of 12/31/06, unless otherwise noted.

       Average Credit Quality of Rated Securities (short-term) (a)         A-1
       -----------------------------------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.

(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.

(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.

(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which
    have been pre-refunded or pre-paid to an earlier date or which have a
    mandatory put date prior to the stated maturity. The average life shown
    takes into account these earlier dates.

(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. For those portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holdings in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in the "AAA"-rating
    category. Percentages are based on the total market value of investments as
    of 12/31/06.

(a) The average credit quality is based upon a market weighted average of
    portfolio holdings that are rated by public rating agencies.
(q) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. If not rated by any of the three
    agencies, the security is considered Not Rated. U.S. Treasuries and U.S.
    Agency securities are included in the "A-1"-rating category. Percentages
    are based on the total market value of investments as of 12/31/06.
(u) For purposes of this graphical presentation, accrued interest, where
    applicable, is included.

Percentages are based on net assets as of 12/31/06, unless otherwise noted.

The portfolio is actively managed and current holdings may be different.

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(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.
(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which
    have been pre-refunded or pre-paid to an earlier date or which have a
    mandatory put date prior to the stated maturity. The average life shown
    takes into account these earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. For those portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holdings in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in the "AAA"-rating
    category. Percentages are based on the total market value of investments as
    of 12/31/06.

Percentages are based on net assets as of 12/31/06, unless otherwise noted.

The portfolio is actively managed and current holdings may be different.

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
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

FINANCIAL HIGHLIGHTS -- continued

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. The total returns in the table
represent the rate by which an investor would have earned (or lost) on an investment in the series share class
(assuming reinvestment of all distributions) held for the entire period. This information has been audited by the
series' independent registered public accounting firm, whose report, together with the series' financial statements,
are included in this report.

MFS/SUN LIFE SERIES TRUST

NOTES TO FINANCIAL STATEMENTS

(1) BUSINESS AND ORGANIZATION
The trust is organized as a Massachusetts business trust and is registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), as an
open-end management investment company consisting of twenty-eight separate
series (the series) of shares: Bond Series*, Capital Appreciation Series,
Capital Opportunities Series, Core Equity Series, Emerging Growth Series,
Emerging 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:

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:

(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

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

(6) LINE OF CREDIT

Each series and other funds managed by MFS participate in a $1 billion
unsecured committed line of credit provided by a syndication of banks under a
credit agreement. 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

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.

GLOBAL GOVERNMENTS SERIES

The Trustees noted the performance of the Series' Initial Class shares was in
the 4th 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 4th 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 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.

GLOBAL TOTAL RETURN SERIES

The Trustees noted the performance of the Series' Initial Class shares was in
the 4th 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 3rd 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

quality of services provided.

the 3rd 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 3rd quintile for the three-year period and the 3rd 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

expense limitation for the Series. The Trustees concluded that the fees were
reasonable in light of the nature and quality of services provided.

the 4th 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

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

median of such fees and expenses of funds in the Lipper expense group. The
Trustees further noted that MFS agreed to reduce its advisory fee to an annual
rate of 0.70% on the first $1 billion of assets. 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.

LETTER FROM THE CEO OF MFS

DEAR CONTRACT OWNERS:

The year 2006 proved to be a very good one for many of the world's financial
markets. 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

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.

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.

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. The total returns in the table represent the rate
by which an investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all
distributions) held for the entire period. This information has been audited by the series' independent registered public
accounting firm, whose report, together with the series' financial statements, are included in this report.

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual resulted in an increase in the net asset value of $0.02 per share based on shares outstanding on
    the day the proceeds were recorded. Excluding the effect of this accrual from the ending net asset value per share, the
    Initial Class and Service Class total returns for the year ended December 31, 2004 would have each been lower by
    approximately 0.11%.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(j) The series' net asset value and total return calculation include proceeds received on March 26, 2003 for the partial
    payment of a non-recurring litigation settlement from Cendant Corporation, recorded as a realized gain on investment
    transactions. The proceeds resulted in an increase in the net asset value of $0.28 per share based on shares outstanding
    on the day the proceeds were received. Excluding the effect of this payment from the ending net asset value per share,
    the Initial Class and Service Class total returns for the year ended December 31, 2003 would have been lower by
    approximately 2.08% and 2.09%, respectively.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the
    total return figures for all periods shown.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual resulted in an increase in the net asset value of $0.01 per share based on shares outstanding on
    the day the proceeds were recorded.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(j) The series' net asset value and total return calculation include proceeds received on March 26, 2003 for the partial
    payment of a non-recurring litigation settlement from Cendant Corporation, recorded as a realized gain on investment
    transactions. The proceeds resulted in an increase in the net asset value of $0.16 per share based on shares outstanding
    on the day the proceeds were received. Excluding the effect of this payment from the ending net asset value per share,
    the Initial Class and Service Class total returns for the year ended December 31, 2003 would have been lower by
    approximately 1.48% and 1.50%, respectively.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the
    total return figures for all periods shown.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual resulted in an increase in the net asset value of $0.01 per share based on shares outstanding on
    the day the proceeds were recorded.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(j) The series' net asset value and total return calculation include proceeds received on March 26, 2003 for the partial
    payment of a non-recurring litigation settlement from Cendant Corporation, recorded as a realized gain on investment
    transactions. The proceeds resulted in an increase in the net asset value of $0.002 per share based on shares
    outstanding on the day the proceeds were received. Excluding the effect of this payment from the ending net asset value
    per share, the Initial Class and Service Class total returns for the year ended December 31, 2003 would have each been
    lower by approximately 0.01%.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the
    total return figures for all periods shown.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

FINANCIAL HIGHLIGHTS -- continued

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. The total returns in the table represent the rate
by which an investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all
distributions) held for the entire period. This information has been audited by the series' independent registered public
accounting firm, whose report, together with the series' financial statements, are included in this report.

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. The total returns in the table represent the rate
by which an investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all
distributions) held for the entire period. This information has been audited by the series' independent registered public

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual resulted in an increase in the net asset value of $0.01 per share based on shares outstanding on
    the day the proceeds were recorded.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(j) The series' net asset value and total return calculation include proceeds received on March 26, 2003 for the partial
    payment of a non-recurring litigation settlement from Cendant Corporation, recorded as a realized gain on investment
    transactions. The proceeds resulted in an increase in the net asset value of $0.06 per share based on shares outstanding
    on the day the proceeds were received. Excluding the effect of this payment from the ending net asset value per share,
    the Initial Class and Service Class total returns for the year ended December 31, 2003 would have each been lower by
    approximately 0.52%.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the
    total return figures for all periods shown.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

FINANCIAL HIGHLIGHTS -- continued

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. The total returns in the table represent the rate
by which an investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all
distributions) held for the entire period. This information has been audited by the series' independent registered public
accounting firm, whose report, together with the series' financial statements, are included in this report.

MFS/SUN LIFE SERIES TRUST

NOTES TO FINANCIAL STATEMENTS

(1) BUSINESS AND ORGANIZATION

The trust is organized as a Massachusetts business trust and is registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), as an
open-end management investment company consisting of twenty-eight separate
series (the series) of shares: Bond Series, Capital Appreciation Series*,
Capital Opportunities Series, Core Equity Series, Emerging Growth Series*,
Emerging 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:

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

(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

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

(6) LINE OF CREDIT

Each series and other funds managed by MFS participate in a $1 billion
unsecured committed line of credit provided by a syndication of banks under a
credit agreement. 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

Sectors Series net assets on that date were $121,536,218, including

loss, and $199,387,276 of accumulated net realized loss on investments and

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

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

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.

determined not to recommend any advisory fee breakpoints for the Series at this
time.

LETTER FROM THE CEO OF MFS

DEAR CONTRACT OWNERS,

The year 2006 proved to be a very good one for many of the world's financial
markets. 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

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.

(c) Security is not a benchmark constituent.
(g) Security was not held in the portfolio at period end.

NOTES TO PERFORMANCE SUMMARY

Initial Class shares have no sales charge. Service Class shares have no sales
charge and carry a 0.25% annual 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

JULY 1, 2006 THROUGH DECEMBER 31, 2006

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.

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. The total returns in the table represent the rate by which an
investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all distributions) held
for the entire period. This information has been audited by the series' independent registered public accounting firm, whose

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual did not have a material impact on the net asset value per share based on the shares outstanding on the
    day the proceeds were recorded.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual did not have a material impact on the net asset value per share based on the shares outstanding on the
    day the proceeds were recorded.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(r) Certain expenses have been reduced without which performance would have been lower.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual resulted in an increase in the net asset value of $0.01 per share based on the shares outstanding on the
    day the proceeds were recorded. Excluding the effect of this accrual from the ending net asset value per share, the Initial
    Class and Service Class total returns for the year ended December 31, 2004 would have been lower by approximately 0.13%.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    re turn figures for all periods shown.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.
(w) Per share amount was less than $0.01.

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

(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with series sales. The
    non-recurring accrual did not have a material impact on the net asset value per share based on the shares outstanding on the
    day the proceeds were recorded.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(r) Certain expenses have been reduced without which performance would have been lower.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.

FINANCIAL HIGHLIGHTS  -- continued

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. The total returns in the table represent the rate by which an
investor would have earned (or lost) on an investment in the series share class (assuming reinvestment of all distributions) held
for the entire period. This information has been audited by the series' independent registered public accounting firm, whose
report, together with the series' financial statements, are included in this report.

MFS/SUN LIFE SERIES TRUST

NOTES TO FINANCIAL STATEMENTS

(1) BUSINESS AND ORGANIZATION

The trust is organized as a Massachusetts business trust and is registered
under the Investment Company Act of 1940, as amended, (the "1940 Act") as an
open-end management investment company consisting of twenty-eight separate
series (the series) of shares: Bond Series, Capital Appreciation Series,
Capital Opportunities Series*, Core Equity Series*, Emerging Growth Series,
Emerging Market Equity Series, Global Governments Series, Global Growth Series,
Global Total Return Series, Government Securities Series, High Yield Series,
International Growth Series*, International Value Series, Massachusetts
Investors Growth Stock Series*, Massachusetts Investors Trust Series, Mid Cap
Growth Series, Mid Cap Value Series*, Money Market Series, New Discovery
Series*, Research Series, Research International Series*, Strategic Growth
Series*, Strategic Income Series, Strategic Value Series*, Technology Series*,
Total Return Series, Utilities Series, and Value Series*. The shares of each
series are sold only to variable accounts established by 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:

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 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.

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

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.

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:

For the year ended December 31, 2006, the actual operating expenses for
Strategic Growth Series and Value 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
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

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

(6) LINE OF CREDIT Each series and other funds managed by MFS participate in a
$1 billion unsecured committed line of credit provided by a syndication of
banks under a credit agreement. 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

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.

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

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,

*   This amount reflects the fees billed to MFS and MFS Related Entities for
    non-audit services relating directly to the operations and financial
    reporting of the Funds (portions of which services also related to the
    operations and financial reporting of other funds within the MFS Funds
    complex).

#   This amount reflects the aggregate fees billed by Deloitte, for non-audit
    services rendered to the Funds and for non-audit services rendered to MFS
    and the MFS 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.

    registrant's internal control over financial reporting.
