LETTER FROM THE CEO OF MFS

DEAR CONTRACT OWNERS,

Most investors are familiar with the basic principles of investing - focus on
the long term and keep your assets diversified across different investment
categories. Still, it is surprising how often we forget these basic lessons.
Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s
had many people hoping they could become millionaires overnight. But the
market decline that started in the spring of 2000 taught everyone how
misguided those hopes had been.

Now, less than six years after the market taught a harsh lesson in the follies
of speculative investing, we are seeing a number of trends that suggest many
investors, including professionals, are hoping for overnight miracles again.
We see a steady stream of market "gurus" on television news shows, promising
to teach amateur investors the strategies that will allow them to get rich
quick. Hedge funds - which by their nature move in and out of investments
rapidly - have soared in popularity in recent years. We are reminded every day
that we live in a "what have you done for me lately?" world, but this mindset
should not influence how we invest and manage our money. In fact, investors
often fall short of their goals because they traded in and out of investments
too frequently and at inopportune times.

Throughout our more than 80-year history, MFS' money management process has
focused on long-term investment opportunities. We firmly believe that the best
way to realize long-term financial goals - be it a college education, a
comfortable retirement, or a secure family legacy - is to follow a three-
pronged approach that focuses on longer time horizons. Allocate holdings
across the major asset classes - including stocks, bonds, and cash. Diversify
within each class to take advantage of different market segments and investing
styles. And rebalance assets regularly to maintain a desired asset
allocation.* This long-term approach requires diligence and patience, two
traits that in our experience are essential to capitalizing on the many
opportunities the financial markets can offer.

    Respectfully,

/s/ Robert J. Manning

    Robert J. Manning
    Chief Executive Officer and Chief Investment Officer
    MFS Investment Management(R)

    February 15, 2006

* Asset allocation, diversification, and rebalancing do not guarantee a profit
  or protect against a loss. The opinions expressed in this letter are those of
  MFS, and no forecasts can be guaranteed.

MANAGEMENT REVIEWS
The following management reviews, for the twelve months ended December 31,
2005, exclude the Money Market Series.

BOND SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 1.75%, while Service Class shares provided a
total return of 1.59%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 2.37% for the series'
benchmark, the Lehman Brothers U.S. Government/Credit Bond Index.

DETRACTORS FROM PERFORMANCE

The portfolio's currency exposure to the euro and the Danish krone detracted
from performance. Throughout the period, the U.S. dollar appreciated against
most major currencies resulting in losses for any unhedged currency positions.
Overweighting "BBB" and "BB"-rated(1) securities acted as a drag on
performance. During the period, spreads between corporate bonds and Treasuries
widened, decreasing the value of corporate bonds. Other areas that detracted
included Treasuries and bonds from the telecommunications sector as these
areas lagged the benchmark.

CONTRIBUTORS TO PERFORMANCE

The portfolio benefited by having a shorter duration(2) than the index, which
was advantageous in a rising interest rate environment. The portfolio enjoyed
a yield advantage over the period and generated a higher level of income than
the index. On a sector basis, strong performance from asset-backed and
mortgage-backed securities, along with the debt of emerging markets,
contributed to relative results. Despite the downgrading and decrease in value
associated with bonds of Ford Motor Credit and General Motors Acceptance Corp,
the banking/finance sector performed well and added to returns.

EMERGING MARKETS EQUITY SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 36.76%, while Service Class shares provided
a total return of 36.36%. These returns do not reflect any applicable contract
or surrender charges and compare with a return of 34.54% for the series'
benchmark, the MSCI Emerging Markets Index.

CONTRIBUTORS TO PERFORMANCE

Overall stock selection was the primary contributor to the portfolio's
performance, led by strong selection in the technology and financial services
sectors. Taiwanese wireless device manufacturer High Tech Computer* was the
top contributing holding as its shares appreciated significantly over the
period. In the financial services sector, the portfolio's  positions in
banking firms Unibanco-Uniao de Bancos Brasileiros (Brazil) and Akbank
(Turkey) boosted relative performance.

Security selection in the consumer staples sector also aided results as
Brazilian brewer Companhia de Bebidas das Americas posted strong gains.
Several individual energy holdings also benefited the portfolio's performance
including Russian integrated oil company LUKOIL and global seamless steel pipe
manufacturer Tenaris.

In other sectors, our positions in South African chemical and fuel company
Sasol*, South African wireless network operator MTN Group, and Brazilian
Internet retailer Submarino*, which is not a benchmark constituent, were among
the portfolio's top contributors for the year.

During the reporting period, the portfolio's currency exposure was a
contributor to relative performance. All of MFS' investment decisions are
driven by the fundamentals of each individual opportunity and, as such, it is
common for our portfolios to have different currency exposure than the
benchmark.

DETRACTORS FROM PERFORMANCE

Security selection in the utilities and communications sector was the main
detractor from relative performance. Within this sector, the portfolio's
holdings in Latin American wireless services provider America Movil* and
Brazilian communications company Brasil Telecom Participacoes* hurt results as
shares of both rose subsequent to their elimination from the portfolio. Not
owning strong-performing benchmark constituent Orascom Telecom Holding, a
wireless network operator in the Middle East and Africa, also hindered
relative results.

Our underweighting of the industrial goods and services sector and stock
selection in the leisure sector dampened relative returns. No individual
holdings in either sector were among the top detractors from performance.

Elsewhere, holdings in Indonesian automaker PT Astra International, Brazilian
paper products manufacturer Votorantim Celulose e Papel, Latin American
appliance and furniture retailer Grupo Elektra*, and insurance and financial
services company Liberty Group* held back results. The portfolio's holdings in
benchmark constituent MOL, a Hungarian integrated oil company, also had a
negative impact on performance as we missed the significant run-up in share
price earlier in the year.

The portfolio's cash position was a detractor from relative performance. The
portfolio holds cash to buy new holdings and to provide liquidity. In a period
when equity markets rose, as measured by the portfolio's benchmark, holding
cash hurt performance versus the benchmark, which has no cash position.

*Security was not held in the portfolio at period-end.

GLOBAL GOVERNMENTS SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of -7.20%, while Service Class shares provided
a total return of -7.49%. These returns do not reflect any applicable contract
or surrender charges and compare with a return of -6.53% for the series'
benchmark, the J.P. Morgan Global Government Bond Index.

During the reporting period ended December 31, 2005, the series' benchmark
changed from the Citigroup World Government Bond Index to the J.P. Morgan
Global Government Bond Index.

DETRACTORS FROM PERFORMANCE

The portfolio's currency positions acted as a drag on relative performance.
During the first half of the period, the portfolio's lower exposure to the
U.S. dollar hurt relative results, as the dollar appreciated relative to most
major currencies. During the period, the index generated a higher level of
income than the portfolio.

CONTRIBUTORS TO PERFORMANCE

The portfolio's duration(2) stance and yield curve(3) positioning aided
relative results throughout the period. The portfolio's positions in longer-
term U.S. and European bonds contributed to performance, as long-term interest
rates declined in the U.S. and Europe. Holdings of asset-backed bonds,
government agencies, and bonds in the finance sector also bolstered results.
Holdings in emerging market debt added to performance, driven primarily by
Russian and Mexican bond positions.

GLOBAL TOTAL RETURN SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 3.83%, while Service Class shares provided a
total return of 3.54%. These returns, which do not reflect any applicable
contract or surrender charges, compare with a return of 10.02% for the series'
benchmark, the MSCI World Index. The series' other benchmark, a blended
benchmark comprised of 60% MSCI World Index and 40% J.P. Morgan Global
Government Bond Index, provided a return of 2.90%. The J.P. Morgan Global
Government Bond Index provided a return of -6.53%.

During the period ended December 31, 2005, the series' benchmark changed from
the Standard & Poor's 500 Stock Index to the MSCI World Index.

DETRACTORS FROM PERFORMANCE

Within the equity portion of the series, stock selection within the financial
services sector detracted from performance relative to the MSCI World Index.
Within the sector, an overweighted position in poor-performing mortgage giant
Fannie Mae held back results.

Stock selection was also challenging in the basic materials sector. Holdings
in paper manufacturer International Paper and chemicals company PPG Industries
detracted from performance relative to the MSCI World Index.

Elsewhere, telecommunications firms Vodafone Group and Deutsche Telekom
weighed on results as both stocks underperformed the index. Other detractors
included Premiere AG in the leisure sector and home builder Masco in the autos
and housing sector.

The cash position in the equity portion of the series was also a detractor
from performance relative to the MSCI World Index. The portfolio holds cash to
buy new holdings and to provide liquidity. In a period when equity markets
rose, as measured by the portfolio's benchmark, holding cash hurt performance
versus the benchmark, which has no cash position.

During the reporting period, currency exposure in the equity portion of the
series detracted from performance relative to the MSCI World Index. All of
MFS' equity investment decisions are driven by the fundamentals of each
individual opportunity and, as such, it is common for our portfolios to have
different currency exposure than the benchmark.

Within the fixed income portion of the series, currency positions held back
performance relative to the J.P. Morgan Global Government Bond Index. During
the first half of the period, the portfolio's lower exposure to the U.S.
dollar hurt results, as the dollar appreciated relative to most major
currencies. During the period, the J.P. Morgan Global Government Bond Index
generated a higher level of income than the portfolio.

CONTRIBUTORS TO PERFORMANCE

Within the equity portion of the series, security selection and an
overweighted position in the strong-performing energy sector boosted
performance relative to the MSCI World Index. The portfolio's holdings in
Statoil*, EnCana, and Unocal* contributed to relative results. Holdings in
ConocoPhillips and Tenaris* (not MSCI World Index constituents) also helped.

A combination of an underweighted position and strong stock selection in the
technology sector contributed to investment results. Holdings in Samsung
Electronics aided returns as the stock outperformed the MSCI World Index.

Stock selection and, to a lesser extent, an underweighted position within the
leisure sector contributed to performance over the period. Within the sector,
overweighting Tokyo Broadcasting* added to relative results.

Elsewhere, holdings in utilities and communications firm Fortum* contributed
to performance relative to the MSCI World Index.

Within the fixed income portion of the series, the stance on duration(2) and
yield curve(3) positioning boosted results relative to the J.P. Morgan Global
Government Bond Index. The portfolio's positions in longer-term U.S. and
European bonds contributed to performance, as long-term interest rates declined
in the U.S. and Europe. The portfolio's holdings of asset-backed bonds,
government agencies, and bonds in the finance sector also bolstered results.
Holdings in emerging market debt added to performance, driven primarily by
Russian and Mexican bond positions.

*Security was not held in the portfolio at period-end.

GOVERNMENT SECURITIES SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 2.30%, while Service Class shares provided a
total return of 2.01%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 2.63% for the series'
benchmark, the Lehman Brothers U.S. Government/Mortgage Bond Index.

DETRACTORS FROM PERFORMANCE

Holding lower-yielding issues relative to the portfolio's benchmark held back
results for the period. Our underweighted position in 30-year mortgage-backed
securities, which outperformed comparable-maturity Treasuries, also detracted
from relative performance.

CONTRIBUTORS TO PERFORMANCE

Toward the end of the period, the portfolio's long duration(2) stance versus
the benchmark contributed to performance as long-term interest rates declined.

HIGH YIELD SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 2.19%, while Service Class shares provided a
total return of 1.93%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 2.74% for the series'
benchmark, the Lehman Brothers U.S. High-Yield Corporate Bond Index.

DETRACTORS FROM PERFORMANCE

Several of the portfolio's holdings in the more speculative "CCC"-rated(1)
sectors of the high yield market held back relative performance during the
period.

Holdings that detracted from relative performance included packaging
manufacturer Pliant, cable TV operator Charter Communications, electrical
contracting and maintenance company Integrated Electrical Services*,
independent power producer Calpine*, and auto parts manufacturer Delphi. The
portfolio's holdings in brokerage company Refco* also hurt relative returns as
the value of the company's debt declined due to its alleged involvement in
fraudulent business practices.

CONTRIBUTORS TO PERFORMANCE

The portfolio's overweighted positions in the debt of commodity chemical
companies contributed to relative returns as this sector outperformed the
overall index. Attractive supply-demand dynamics, which boosted earnings and
cash flows, enabled these companies to decrease leverage. Our position in
chemical company Rhodia was among the portfolio's top contributing securities.

The portfolio benefited from several individual holdings that performed well
during the period, including television broadcaster Paxson Communications and
oil and gas company Kerr-McGee.

* Security was not held in the portfolio at period-end.

INTERNATIONAL VALUE SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 15.22%, while Service Class shares provided
a total return of 14.86%. These returns do not reflect any applicable contract
or surrender charges and compare with a return of 14.02% for the series'
benchmark, the MSCI EAFE Index. The portfolio's other benchmark, the MSCI EAFE
Value Index, provided a return of 14.39%.

CONTRIBUTORS TO PERFORMANCE

Stock selection and, to a lesser extent, our overweighting in the strong-
performing energy sector was the primary contributor to the portfolio's
performance relative to the benchmark. Within this sector, Norwegian oil and
gas company Statoil* was the top contributor as the stock posted solid gains
for the period. Other energy holdings that aided results included Canadian oil
and gas producer EnCana, global seamless steel pipe manufacturer Tenaris*, and
French steel tube maker Vallourec, none of which are benchmark constituents.

Strong security selection in the utilities and communications sector, led by
Finnish energy provider Fortum*, contributed to the portfolio's relative
performance.

The portfolio's underweighting in the technology sector helped results as the
sector's returns lagged that of the overall benchmark. Within technology,
South Korean electronics manufacturer Samsung Electronics, which is not a
benchmark constituent, was a particularly strong performer, adding to
benchmark relative returns.

In other sectors, Japanese apparel maker Sanyo Shokai and UK-based airline
operator easyJet*, neither of which are benchmark constituents, boosted
relative returns. Japanese commercial broadcaster Tokyo Broadcasting Systems*
was the top contributing stock to relative performance.

During the reporting period, the portfolio's currency exposure was a
contributor to relative performance. All of MFS' investment decisions are
driven by the fundamentals of each individual opportunity and, as such, it is
common for our portfolios to have different currency exposure than the
benchmark.

DETRACTORS FROM PERFORMANCE

A combination of security selection and underweighted positions in the strong-
performing basic materials and industrial goods and services sectors held back
performance relative to the benchmark. No individual securities in either
sector were among the portfolio's top detractors during the period.

Stock selection in the autos and housing sector also hurt benchmark relative
performance. No individual securities in this sector were among the
portfolio's greatest detractors.

Although the utilities and communications and the technology sectors were top
contributing sectors over the period, several individual holdings in both
sectors hindered performance. These included UK-based wireless service
provider Vodafone Group and German telecommunications company Deutsche Telekom
in the former sector, and Japanese electronic devices manufacturer Seiko
Epison in the latter sector.

Among the portfolio's holdings, German pay-television operator Premiere had
the greatest negative impact on returns as the stock significantly
underperformed the benchmark. Elsewhere, positions in North American frozen
dessert maker CoolBrands International and UK supermarket chain William
Morrison Supermarkets, neither of which are benchmark constituents, detracted
from relative results.

The portfolio's cash position was also a detractor from relative performance.
The portfolio holds cash to buy new holdings and to provide liquidity. In a
period when equity markets rose, as measured by the portfolio's benchmark,
holding cash hurt performance versus the benchmark, which has no cash
position.

* Security was not held in the portfolio at period-end.

STRATEGIC INCOME SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 1.89%, while Service Class shares provided a
total return of 1.61%. These returns do not reflect any applicable contract or
surrender charges and compare with the following returns over the same period
for the series' benchmarks: 10.73% for the J.P. Morgan Emerging Markets Bond
Index Global, 2.74% for the Lehman Brothers U.S. High-Yield Corporate Bond
Index, 5.69% for the Citigroup World Government Bond Non-Dollar Hedged Index,
and 2.43% for the Lehman Brothers U.S. Aggregate Bond Index.

DETRACTORS FROM PERFORMANCE

The portfolio's position in weak-performing "BB"- and "BBB"-rated(1)
securities held back performance during the period.

The portfolio's foreign currency exposure also detracted from results as the
U.S. dollar was strong versus most developed market currencies throughout the
year. Among individual holdings, packaging company Pliant was among the
portfolio's top detractors for the period.

CONTRIBUTORS TO PERFORMANCE

The portfolio's duration(2) stance boosted investment results as short-term
rates rose during the period. The portfolio's positioning along the yield
curve(3) and our holdings of some emerging market sovereign bonds from the
governments of Brazil, Russia, and Panama also contributed to performance.

(b) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(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 a "AAA"-rating category. Percentages are
    based on the total market value of investments as of 12/31/05.
(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 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.
(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 price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a fund with a
    5-year duration is likely to lose about 5.00% of its value.

Percentages are based on net assets as of 12/31/05, unless otherwise noted.

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

(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 a "AAA"-rating category. Percentages are
    based on the total market value of investments as of 12/31/05.
(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 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.
(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 price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a fund with a
    5-year duration is likely to lose about 5.00% of its value.

(b) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(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 a "AAA"-rating category. Percentages are
    based on the total market value of investments as of 12/31/05.
(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 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.
(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 price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a fund with a
    5-year duration is likely to lose about 5.00% of its value.

Percentages are based on net assets as of 12/31/05, 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
ffect during the periods shown; without these the results would have been less
favorable. See the prospectus for details. All results are historical and assume
the reinvestment of any dividends and capital gains distributions.

Money Market Series performance results reflect any applicable expense
subsidies, waivers and adjustments in effect during the periods shown.
Subsidies and fee waivers may be imposed to enhance a portfolio's yield during
periods when the portfolio's operating expenses have a significant impact on
the portfolio's yield due to lower interest rates. Without such subsidies,
waivers and adjustments, the results would have been less favorable. See the
prospectus for details. All results are historical and assume the reinvestment
of dividends and capital gains.

The returns for the series shown do not reflect the deduction of expenses
associated with variable products, such as mortality and expense risk charges,
separate account charges, and sales charges imposed by insurance company
separate accounts. Such expenses would reduce the overall returns shown.

From time to time the series may receive proceeds from litigation settlements,
without which performance would be lower.

KEY RISK CONSIDERATIONS

BOND SERIES

The portfolio's yield and share prices change daily based on the credit
quality of its investments and changes in interest rates. In general, the
value of debt securities will decline when interest rates rise and will
increase when interest rates fall. Debt securities with longer maturity dates
will be subject to greater price fluctuations than those with shorter
maturities. Mortgage securities are subject to prepayment risk which can offer
less potential for gains in a declining interest rate environment and greater
potential for loss in a rising interest rate environment. Derivatives involve
risks different from, and greater than, those of the underlying indicator(s)
in whose value the derivative is based. The value of the derivative can move
in unexpected ways and result in unanticipated losses and increased volatility
if the value of the underlying indicator(s) does not move in the direction or
the extent anticipated. Foreign investments can be more volatile than U.S.
investments.

EMERGING MARKET EQUITY SERIES

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

GLOBAL GOVERNMENTS SERIES

The portfolio's yield and share prices change daily based on the credit
quality of its investments and changes in interest rates. In general, the
value of debt securities will decline when interest rates rise and will
increase when interest rates fall. Debt securities with longer maturity dates
will be subject to greater price fluctuations than those with shorter
maturities. Mortgage securities are subject to prepayment risk which can offer
less potential for gains in a declining interest rate environment and greater
potential for loss in a rising interest rate environment. Derivatives involve
risks different from, and greater than, those of the underlying indicator(s)
in whose value the derivative is based. The value of the derivative can move
in unexpected ways and result in unanticipated losses and increased volatility
if the value of the underlying indicator(s) does not move in the direction or
the extent anticipated. Because MFS may invest a relatively large percentage
of the portfolio's assets in issuers located in a single country or a small
number of countries, the portfolio's performance could be closely tied to the
market, economic, political or regulatory conditions and developments in those
countries and could be more volatile than the performance of more
geographically diversified portfolios. Foreign investments can be more
volatile than U.S. investments. Changes in currency exchange rates may affect
the portfolio's net asset value, the value of dividends and interest earned,
and gains and losses realized on the sale of securities. Investing in emerging
markets can involve risks in addition to those generally associated with
investing in more developed foreign markets. Because the portfolio is
considered non-diversified, MFS may invest a significant percentage of the
portfolio's assets in a single issuer or a small number of issuers.

GLOBAL TOTAL RETURN SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Investing in emerging markets can

yield and share prices change daily based on the credit quality of its
investments and changes in interest rates. In general, the value of debt
securities will decline when interest rates rise and will increase when
interest rates fall. Debt securities with longer maturity dates will be
subject to greater price fluctuations than those with shorter maturities.
Derivatives involve risks different from, and greater than, those of the
underlying indicator(s) in whose value the derivative is based. The value of
the derivative can move in unexpected ways and result in unanticipated losses
and increased volatility if the value of the underlying indicator(s) does not
move in the direction or the extent anticipated.

GOVERNMENT SECURITIES SERIES

The portfolio's yield and share prices change daily based on the credit
quality of its investments and changes in interest rates. In general, the
value of debt securities will decline when interest rates rise and will
increase when interest rates fall. Debt securities with longer maturity dates
will be subject to greater price fluctuations than those with shorter
maturities. Mortgage securities are subject to prepayment risk which can offer
less potential for gains in a declining interest rate environment and greater

in whose value the derivative is based. The value of the derivative can move
in unexpected ways and result in unanticipated losses and increased volatility
if the value of the underlying indicator(s) does not move in the direction or
the extent anticipated.

HIGH YIELD SERIES

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

INTERNATIONAL VALUE SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Changes in currency exchange rates may
affect the portfolio's net asset value, the value of dividends and interest
earned, and gains and losses realized on the sale of securities. Investing in
emerging markets can involve risks in addition to those generally associated
with investing in more developed foreign markets. Because MFS may invest a
relatively large percentage of the portfolio's assets in issuers located in a
single country or a small number of countries, the portfolio's performance
could be closely tied to the market, economic, political or regulatory
conditions and developments in those countries and could be more volatile than
the performance of more geographically diversified portfolios.  Value stocks
may perform differently from the general stock market and can continue to be
undervalued for long periods of time and not realize their full value.

MONEY MARKET SERIES

The portfolio's yield changes daily and is are based on changes in interest
rates and market conditions, and in response to other economic, political, or
financial developments. The value of the portfolio's investments may fluctuate
in response to many factors including the performance and valuation of the
issuer and general market conditions. Foreign investments can be more volatile
than U.S. investments. The value of the portfolio's domestic investments will
fluctuate. Investors should note that while securities issued by certain U.S.
government agencies or instrumentalities are guaranteed by the U.S.
government, securities issued by many U.S. government agencies are not
guaranteed by the U.S. government. Although the portfolio(s) seek to preserve
the value of your investment at $1.00 per share, it is possible to lose money
by investing in the portfolio.

STRATEGIC INCOME SERIES

The portfolio's yield and share prices change daily based on the credit
quality of its investments and changes in interest rates. In general, the
value of debt securities will decline when interest rates rise and will
increase when interest rates fall. Debt securities with longer maturity dates
will be subject to greater price fluctuations than those with shorter
maturities. Mortgage securities are subject to prepayment risk which can offer
less potential for gains in a declining interest rate environment and greater
potential for loss in a rising interest rate environment. Derivatives involve
risks different from, and greater than, those of the underlying indicator(s)
in whose value the derivative is based. The value of the derivative can move
in unexpected ways and result in unanticipated losses and increased volatility
if the value of the underlying indicator(s) does not move in the direction or
the extent anticipated.  Lower quality debt securities involve substantially
greater risk of default and their value can decline significantly over time.
Foreign investments can be more volatile than U.S. investments. Investing in
emerging markets can involve risks in addition to those generally associated
with investing in more developed foreign markets.

EXPENSE TABLES
SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD,
JULY 1, 2005 THROUGH DECEMBER 31, 2005

As a shareholder of the series, you incur ongoing costs, including management
fees; distribution (12b-1) fees; and other series expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing
in the series and to compare these costs with the ongoing costs of investing
in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period, July 1, 2005 through December 31,
2005.

ACTUAL EXPENSES
The first line for each share class in the following tables provides
information about actual account values and actual expenses. You may use the
information in this line, together with the amount you invested, to estimate
the expenses that you paid over the period. Simply divide your account value
by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number in the first line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your
account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line for each share class in the following tables provides
information about hypothetical account values and hypothetical expenses based
on the series' actual expense ratio and an assumed rate of return of 5% per
year before expenses, which is not the series' actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the series and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight the
series' ongoing costs only and do not take into account the fees and expenses
imposed under the variable contracts through which your investment in the
series is made. Therefore, the second line for each share class in the tables
is useful in comparing ongoing costs associated with an investment in vehicles
(such as the series) which fund benefits under variable annuity and variable
life insurance contracts and to qualified pension and retirement plans only,
and will not help you determine the relative total costs of investing in the
series through variable annuity and variable life insurance contracts. If the
fees and expenses imposed under the variable contracts were included, your
costs would have been higher.

FINANCIAL HIGHLIGHTS

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.

(i) For the period from the class' inception, August 24, 2001 (Service Class) through the stated period end.
(a) Annualized.
(n) Not annualized.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect expense 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.
(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the
    timing of sales of series shares and the amount of per share realized and unrealized gains and losses at such time.

MFS/SUN LIFE SERIES TRUST

FINANCIAL HIGHLIGHTS -- continued

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or
life of a particular 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.

FINANCIAL HIGHLIGHTS -- continued

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or
life of a particular 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.

FINANCIAL HIGHLIGHTS -- continued

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

MFS/SUN LIFE SERIES TRUST

NOTES TO FINANCIAL STATEMENTS

(1) BUSINESS AND ORGANIZATION
The Trust is organized as a Massachusetts business trust and is registered
under the Investment Company Act of 1940, as amended, as an open-end
management investment company consisting of twenty-eight separate series (the
series) of shares: Bond Series*, Capital Appreciation Series, Capital
Opportunities Series, Core Equity Series, Emerging Growth Series, Emerging
Markets Equity Series*, Global Governments Series*, Global Growth Series,
Global Total Return Series*, Government Securities Series*, High Yield
Series*, International Growth Series, International Value Series*,
Massachusetts Investors Growth Stock Series, Massachusetts Investors Trust
Series, Mid Cap Growth Series, Mid Cap Value Series, Money Market Series*, New
Discovery Series, Research Series, Research International Series, Strategic
Growth Series, Strategic Income Series*, Strategic Value Series, Technology
Series, Total Return Series, Utilities Series and Value Series. The shares of
each series are sold only to variable accounts established by Sun Life
Assurance Company of Canada (U.S.) and Sun Life Insurance and Annuity Company
of New York to fund benefits under variable contracts issued by such
companies.

The series denoted with an asterisk above are included within these financial
statements.

(2) SIGNIFICANT ACCOUNTING POLICIES
General - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
and disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates. High
Yield Series can invest up to 100% of its portfolio in high-yield securities
rated below investment grade. Investments in high-yield securities involve
greater degrees of credit and market risk than investments in higher-rated
securities and tend to be more sensitive to economic conditions. Certain
series can invest in foreign securities, including securities of emerging
market issuers. Investments in foreign securities are vulnerable to the
effects of changes in the relative values of the local currency and the U.S.
dollar and to the effects of changes in each country's legal, political, and
economic environment. The markets of emerging markets countries are generally
more volatile than the markets of developed countries with more mature
economies. All of the risks of investing in foreign securities previously
described are heightened when investing in emerging markets countries.

Investment Valuations - Money market instruments are valued at amortized cost,
which approximates market value. Amortized cost involves valuing an instrument
at its cost as adjusted for amortization of premium or accretion of discount
rather than its current market value. Each money market fund's use of
amortized cost is subject to the fund's compliance with Rule 2a-7 of the
Investment Company Act of 1940. The amortized cost value of an instrument can
be different from the market value of an instrument. Equity securities,
including restricted equity securities, are generally valued at the last sale
or official closing price as reported by an independent pricing service on the
market or exchange on which they are primarily traded. For securities for
which there were no sales during the day, equity securities are generally
valued at the last quoted bid price as reported by an independent pricing
service on the market or exchange on which they are primarily traded. Debt
instruments (other than short-term instruments), including restricted debt
instruments, are generally valued at an evaluated bid price as reported by an
independent pricing service. Values of debt instruments obtained from pricing
services can utilize both dealer-supplied valuations and electronic data
processing techniques which take into account factors such as institutional-
size trading in similar groups of securities, yield, quality, coupon rate,
maturity, type of issue, trading characteristics and other market data. Short-
term instruments with a maturity at issuance of 365 days or less are generally
valued at amortized cost, which approximates market value. Exchange-traded
options are generally valued at the last sale or closing price as reported by
an independent pricing service on the exchange on which they are primarily
traded. For exchange-traded options in which there were no sales during the
day, exchange-traded options are generally valued at the last quoted bid price
as reported by an independent pricing service on the exchange on which they
are primarily traded. Options not traded on an exchange are generally valued
as reported by an independent pricing service or on the basis of quotations
obtained from brokers and dealers. Foreign currency options are generally
valued using an external pricing model that uses market data from an
independent source. Futures contracts are generally valued at settlement price
as reported by an independent pricing service on the exchange on which they
are primarily traded. For futures contracts in which there were no sales
during the day, futures contracts are generally valued at the last quoted bid
price as reported by an independent pricing service on the exchange on which
they are primarily traded. Forward foreign currency contracts are generally
valued at the mean of bid and asked prices based on rates reported by an
independent pricing service. Swaps are generally valued on the basis of
quotations from brokers and dealers. Open-end investment companies are
generally valued at their net asset value per share. Securities and other
assets generally valued on the basis of information from an independent
pricing service may also be valued on the basis of information from brokers
and dealers. The values of foreign securities and other assets and liabilities
expressed in foreign currencies are converted to U.S. dollars based upon
exchange rates provided by an independent source. When pricing-service
information or market quotations are not readily available, securities are
priced at fair value as determined under the direction of the Board of
Trustees. For example, in valuing securities that trade principally on foreign
markets, events reasonably determined to be significant (such as certain
movements in the U.S. securities market, or other regional and local
developments) may occur between the time that foreign markets close (where the
security is principally traded) and the series' valuation time that may impact
the value of securities traded in these foreign markets. In these cases, the
series may utilize information from an external vendor or other sources to
adjust closing market prices of foreign equity securities to reflect what it
believes to be the fair value of the securities as of the series' valuation
time. Fair valuation of foreign equity securities may occur frequently based
on an assessment that events which occur on a fairly regular basis (such as
U.S. market movements) are significant.

Repurchase Agreements - Each series may enter into repurchase agreements with
institutions that the series' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The series
requires that the securities collateral in a repurchase transaction be
transferred to the custodian in a manner sufficient to enable the series to
obtain those securities in the event of a default under the repurchase
agreement. Each series monitors, on a daily basis, the value of the collateral
to ensure that its value, including accrued interest, is greater than amounts
owed to the series under each such repurchase agreement. Each series, along
with other affiliated entities of Massachusetts Financial Services Company
(MFS), may utilize a joint trading account for the purpose of entering into
one or more repurchase agreements.

Inflation-Adjusted Debt Securities - Certain series invest in inflation-
adjusted debt securities issued by the U.S. Treasury. Certain series may also
invest in inflation-adjusted debt securities issued by U.S. Government
agencies and instrumentalities other than the U.S. Treasury and by other
entities such as U.S. and foreign corporations and foreign governments. The
principal value of these debt securities is adjusted by references to changes
in the Consumer Price Index or another general price or wage index. These debt
securities typically pay a fixed rate of interest, but this fixed rate is
applied to the inflation-adjusted principal amount. The principal paid at
maturity of the debt security is typically equal to the inflation-adjusted
principal amount, or the security's original par value, whichever is greater.
Other types of inflation-adjusted securities may use other methods to adjust
for other measures of inflation.

Foreign Currency Translation - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of
both realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

Derivative Risk - Each series may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When each series uses derivatives as an investment
to gain market exposure, or for hedging purposes, gains and losses from
derivative instruments may be substantially greater than the derivative's
original cost. Derivative instruments include written options, purchased
options, forward foreign currency exchange contracts, swap agreements, short
sales, and futures contracts.

Purchased Options - Each series may purchase call or put options for a
premium. Purchasing call options may be a hedge against an anticipated
increase in the dollar cost of securities to be acquired or to increase the
series' exposure to the underlying instrument. Purchasing put options may
hedge against a decline in the value of portfolio securities. The premium paid
is included as an investment in the Statement of Assets and Liabilities and is
subsequently adjusted to the current value of the option. Premiums paid for
purchased options which have expired are treated as realized losses on
investments in the Statement of Operations. Premiums paid for purchased
options which are exercised or closed are added to the amount paid or offset
against the proceeds on the underlying security or financial instrument to
determine the realized gain or loss. The risk of loss associated with
purchased options is limited to the premium paid.

Futures Contracts - Each series may enter into futures contracts for the
delayed delivery of securities or currency, or contracts based on financial
indices at a fixed price on a future date. In entering such contracts, each
series is required to deposit with the broker either in cash or securities an
amount equal to a certain percentage of the contract amount. Subsequent
payments are made or received by each series each day, depending on the daily
fluctuations in the value of the contract, and are recorded for financial
statement purposes as unrealized gains or losses by the series. Upon entering
into such contracts, each series bears the risk of interest or exchange rates
or securities prices moving unexpectedly, in which case, each series may not
achieve the anticipated benefits of the futures contracts and may realize a
loss.

Forward Foreign Currency Exchange Contracts - Each series may enter into
forward foreign currency exchange contracts for the purchase or sale of a
specific foreign currency at a fixed price on a future date. Risks may arise
upon entering into these contracts from the potential inability of
counterparties to meet the terms of their contracts and from unanticipated
movements in the value of the contract. Each series may enter into forward
foreign currency exchange contracts for hedging purposes as well as for non-
hedging purposes. For hedging purposes, each series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. Each series may also use contracts in a manner
intended to protect foreign currency denominated securities from declines in
value due to unfavorable exchange rate movements. For non-hedging purposes,
each series may enter into contracts with the intent of changing the relative
exposure of the series' portfolio of securities to different currencies to
take advantage of anticipated changes. The forward foreign currency exchange
contracts are adjusted by the daily exchange rate of the underlying currency
and any gains or losses are recorded as unrealized until the contract
settlement date. On contract settlement date, the gains or losses are recorded
as realized gains or losses on foreign currency transactions.

Swap Agreements - Each series may enter into swap agreements. A swap is an
exchange of cash payments between the series and another party. Net cash
payments are exchanged at specified intervals and are recorded as a realized
gain or loss in the Statement of Operations. The value of the swap is adjusted
daily and the change in value is recorded as unrealized appreciation or
depreciation in the Statement of Operations. Risks may arise upon entering
into these agreements from the potential inability of counterparties to meet
the terms of their contract and from unanticipated changes in the value of the
financial index on which the swap agreement is based.

Each series may enter into credit default swaps to limit or to reduce risk
exposure of the series to defaults of corporate and sovereign issuers. The
series may also use credit default swaps to create direct or synthetic short
or long exposure to domestic or foreign corporate debt securities or certain
sovereign debt securities to which the series is not otherwise exposed. In a
credit default swap, one party makes a stream of payments to another party in
exchange for the right to receive a specified return in the event of a default
by a third party, such as a corporate issuer or foreign issuer, on its
obligation.

Security Loans - State Street Bank and Trust Company ("State Street") and J.P.
Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of
certain series to certain qualified institutions (the "Borrowers") approved by
the series. The loans are collateralized at all times by cash and/or U.S.
Treasury securities in an amount at least equal to the market value of the
securities loaned. State Street and Chase provide certain series with
indemnification against Borrower default. Each series bears the risk of loss
with respect to the investment of cash collateral. On loans collateralized by
cash, the cash collateral is invested in a money market fund or short-term
securities. A portion of the income generated upon investment of the
collateral is remitted to the Borrowers, and the remainder is allocated
between the series and the lending agents. On loans collateralized by U.S.
Treasury securities, a fee is received from the Borrower, and is allocated
between the series and the lending agents. The dividend and interest income
earned on the securities loaned is accounted for in the same manner as other
dividend and interest income.

Dollar Roll Transactions - Certain series enter into dollar roll transactions,
with respect to mortgage backed securities issued by Ginnie Mae, Fannie Mae,
and Freddie Mac, in which the series sells mortgage backed securities to
financial institutions and simultaneously agrees to accept substantially
similar (same type, coupon, and maturity) securities at a later date at an
agreed-upon price. During the period between the sale and repurchase in a
dollar roll transaction the series will not be entitled to receive interest
and principal payments on the securities sold but is compensated by interest
earned on the proceeds of the initial sale and by a lower purchase price on
the securities to be repurchased which enhances the series' total return. Each
series accounts for dollar roll transactions as purchases and sales. If
certain criteria are met these dollar roll transactions may be considered a
financing transaction whereby the difference in the sales price and the future
purchase price is recorded as an adjustment to interest income.

Investment Transactions and Income - Investment transactions are recorded on
the trade date. Some securities may be purchased on a "when-issued" or
"forward delivery" basis, which means that the securities will be delivered to
the series at a future date, usually beyond customary settlement time.
Interest income is recorded on the accrual basis. All premium and discount is
amortized or accreted for financial statement purposes in accordance with U.S.
generally accepted accounting principles. All discount is accreted for tax
reporting purposes as required by federal income tax regulations. For Money
Market Series, all premium and discount is amortized and accreted for
financial statement purposes and tax reporting purposes in accordance with
generally accepted accounting principles and federal tax regulations,
respectively. Dividends received in cash are recorded on the ex-dividend date.
Certain dividends from foreign securities will be recorded as soon as the
series is informed of the dividend if such information is obtained subsequent
to the ex-dividend date. Dividend and interest payments received in additional
securities are recorded on the ex-dividend or ex-interest date in an amount
equal to the value of the security on such date.

Certain series may receive proceeds from litigation settlements involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss
in the Statements of Operations, or in unrealized gain/loss if the security is
still held by the series.

Certain series may enter into "TBA" (to be announced) purchase commitments to
purchase securities for a fixed unit price at a future date. Although the unit
price has been established, the principal value has not been finalized.
However, the principal amount of the commitments will not fluctuate more than
0.01%. The series holds, and maintains until settlement date, cash or high-
grade debt obligations in an amount sufficient to meet the purchase price, or
the series may enter into offsetting contracts for the forward sale of other
securities it owns. Income on the securities will not be earned until
settlement date. TBA purchase commitments may be considered securities in
themselves, and involve a risk of loss if the value of the security to be
purchased declines prior to settlement date, which is in addition to the risk
of decline in the value of the series' other assets. Unsettled TBA purchase
commitments are valued at the current market value of the underlying
securities.

Certain series may enter into "TBA" (to be announced) sale commitments to
hedge its portfolio positions or to sell mortgage-backed securities it owns
under delayed delivery arrangements. Proceeds of TBA sale commitments are not
received until the contractual settlement date. During the time a TBA sale
commitment is outstanding, equivalent deliverable securities, or an offsetting
TBA purchase commitment deliverable on or before the sale commitment date, are
held as "cover" for the transaction.

Fees Paid Indirectly - Each series' custody fees are reduced according to an
arrangement that measures the value of cash deposited with the custodian by
the series. During the year ended December 31, 2005, certain series' custodian
fees were reduced under this arrangement as noted below. Certain series have
entered into a commission recapture agreement, under which certain brokers
will credit the series a portion of the commissions generated, to offset
certain expenses of the series. For the year ended December 31, 2005, each
series' custodian expenses were reduced under this agreement as noted below.
These amounts are shown as a reduction of total expenses on the Statements of
Operations.

Tax Matters and Distributions - Each series intends to continue 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 each
series in the accompanying financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share.
Temporary differences which arise from recognizing certain items of income,
expense, gain or loss in different periods for financial statement and tax
purposes will reverse at some time in the future. Distributions in excess of
net investment income or net realized gains are temporary over distributions
for financial statement purposes resulting from differences in the recognition
or classification of income for financial statement and tax purposes.

Book/tax differences primarily relate to net operating losses, amortization
and accretion of debt securities, defaulted bonds, passive foreign investment
companies, wash sale loss deferrals, straddle loss deferrals, foreign currency
transactions and derivative transactions.

The tax character of distributions declared to shareholders is as follows:

(1) The availability of a portion of these respective capital loss carryforwards, which were acquired on September 5, 2003,

Multiple Classes of Shares of Beneficial Interest - Each series offers
multiple classes of shares, which differ in their respective distribution
fees. All shareholders bear the common expenses of the series based on daily
net assets of each class, without distinction between share classes. Dividends
are declared separately for each class. Differences in per share dividend
rates are generally due to differences in separate class expenses.

(3) TRANSACTIONS WITH AFFILIATES
Investment Adviser - Each series has an investment advisory agreement with MFS
to provide overall investment advisory and administrative services, and
general office facilities.

The management fee is computed daily and paid monthly at an annual rate based
on a percentage of each series' average daily net assets
as follows:

Bond Series: The management fee is 0.60% of average daily net assets.

Emerging Markets Equity Series: The management fee is 1.05% of the first $500
million of average daily net assets and 1.00% of average daily net assets in
excess of $500 million.

Global Governments Series: The management fee is 0.75% of the first $300
million of average daily net assets and 0.675% of average daily net assets in
excess of $300 million.

Global Total Return Series: The management fee is 0.75% of the first $300
million of average daily net assets and 0.675% of average daily net assets in
excess of $300 million.

Government Securities Series: Prior to September 1, 2005 the management fee
was 0.55% of the series' average daily net assets. Effective September 1,
2005, the management fee is 0.55% of the first $1 billion of average daily net
assets and 0.50% of average daily net assets in excess of $1 billion.

High Yield Series: The management fee is 0.75% of average daily net assets.
The investment adviser has contractually agreed to waive its fee to 0.70% of
average daily net assets in excess of $1 billion. This reduction of the
management fee may be rescinded by MFS only with the approval of the series'
Board of Trustees.

International Value Series: The management fee is 0.90% of the first $1
billion of average daily net assets, 0.80% of the next $1 billion of average
daily net assets and 0.70% of average daily net assets in excess of $2
billion.

Money Market Series: The management fee is 0.50% of average daily net assets.
The investment adviser has contractually agreed to waive its fee to 0.45% of
average daily net assets in excess of $500 million. This reduction of the
management fee may be rescinded by MFS only with the approval of the series'
Board of Trustees.

Strategic Income Series: Prior to September 1, 2005 the management fee was
0.75% of the series' average daily net assets. Effective September 1, 2005, the
management fee is 0.75% of the first $1 billion of average daily net assets and
0.65% of average daily net assets in excess of $1 billion. The investment
adviser has contractually agreed to waive its fee to 0.65% of average daily net
assets in excess of $500 million for the period September 1, 2005, through
April 30, 2007. This reduction of the management fee may be rescinded by MFS
only with the approval of the series' Board of Trustees.

The investment adviser has agreed to pay a portion of certain series' total
operating expenses, exclusive of certain fees and expenses, such that the
operating expenses of these series do not exceed the expense limitations
indicated below, based on the average daily net assets of such series. For the
year ended December 31, 2005, this agreement is reflected as a reduction of
total expenses in the Statements of Operations for these series.

The management fees and expense limitations incurred for the year ended
December 31, 2005 were equivalent to an annual effective rate of each series'
average daily net assets as follows:
                                     Effective   Initial Class    Service Class

    reduction was $19,764 and $2,087, respectively.

Distributor - MFS Fund Distributors, Inc. (MFD), a wholly owned subsidiary of
MFS, is the distributor of shares of the series. The Trustees have adopted a
distribution plan for the Service Class shares pursuant to Rule 12b-1 under
the Investment Company Act of 1940.

The series' distribution plan provides that each series will pay MFD
distribution fees equal to 0.25% per annum of its average daily net assets
attributable to Service Class shares as partial consideration for services
performed and expenses incurred by MFD and financial intermediaries in
connection with the sale and distribution of the series' Service Class shares
and the sale and distribution of the variable annuity or variable life
insurance contracts investing indirectly in Service Class shares. MFD may
subsequently pay all, or a portion, of the distribution fees to financial
intermediaries.

Administrator - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to each series
and certain other MFS funds (the funds) for which MFS acts as investment
adviser. Under an administrative services agreement, the funds may partially
reimburse MFS the costs incurred to provide these services, subject to review
and approval by the Board of Trustees. Each fund is allocated a portion of
these administrative costs based on its size and relative average net assets.
The administrative services fee incurred for the year ended December 31, 2005
was equivalent to an annual effective rate of each series' average daily net
assets as follows:

                                                     % of Average
                                                   Daily Net Assets

Trustees' and Officers' Compensation -  Each series pays compensation to
Independent Trustees in the form of a retainer, attendance fees, and
additional compensation to the Board chairperson. Each series does not pay
compensation directly to Trustees who are officers of the investment adviser,
or to officers of the series, all of whom receive remuneration for their
services to the series from MFS. Certain officers and Trustees of the series
are officers or directors of MFS, MFD, and MFS Service Center, Inc. (MFSC).

Other - The funds have entered into a services agreement (the Agreement) which
provides for payment of fees by the funds to Tarantino LLC in return for the
provision of services of an Independent Chief Compliance Officer (ICCO) for the
funds. The ICCO is an officer of the funds and the sole member of Tarantino
LLC. MFS has agreed to bear all expenses associated with office space, other
administrative support, and supplies provided to the ICCO. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement. For the year ended December 31, 2005, payments made by the series to
Tarantino LLC amounted to the following and are included in miscellaneous
expense in the Statements of Operations:

participating funds at the end of each calendar quarter. The commitment fee
allocated to each series for the year ended December 31, 2005 is included in
miscellaneous expense on the Statements of Operations and is as follows for

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,

"Trust"), comprising Bond Series, Emerging Markets Equity Series, Global
Governments Series, Global Total Return Series, Government Securities Series,
High Yield Series, International Value Series, Money Market Series and
Strategic Income Series as of December 31, 2005, and the related statements of
operations for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Trust is not required to have, nor were we engaged to
perform, an audit of its internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Trust's internal control over financial reporting. Accordingly, we express no
such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
as well as evaluating the overall financial statement presentation. Our
procedures included confirmation of securities owned as of December 31, 2005,
by correspondence with the custodian and brokers; where replies were not
received from brokers, we performed other auditing procedures. We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial positions of Bond Series,
Emerging Markets Equity Series, Global Governments Series, Global Total Return
Series, Government Securities Series, High Yield Series, International Value
Series, Money Market Series and Strategic Income Series as of December 31,
2005, the results of their operations for the year then ended, the changes in
their net assets for each of the two years in the period then ended, and their
financial highlights for each of the five years in the period then ended, in
conformity with accounting principles generally accepted in the United States
of America.

BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENTS

The Investment Company Act of 1940 requires that both the full Board of Trustees
and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Trust's investment advisory
agreements with Massachusetts Financial Services Company (MFS) on behalf of the
Series. The Trustees consider matters bearing on the Series and their advisory
arrangements at their meetings throughout the year, including a review of
performance data at each regular meeting. In addition, the independent Trustees
met several times over the course of three months beginning in May and ending in
July 2005 ("contract review meetings") for the specific purpose of considering
whether to approve the continuation of the investment advisory agreements for
the Series. The independent Trustees were assisted in their evaluation of the
investment advisory agreements by independent legal counsel, from whom they
received separate legal advice and with whom they met separately from MFS
management during various contract review meetings. The independent Trustees
were also assisted in this process by the Series' Independent Chief Compliance
Officer, a full-time senior officer appointed by and reporting to the
independent Trustees.

In connection with their deliberations, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light of
the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreements were considered separately for each
Series, although the Trustees also took into account the common interests of all
Series in their review. As described below, the Trustees considered the nature,
quality, and extent of the various investment advisory, administrative, and
shareholder services performed by MFS under the existing investment advisory
agreements and other arrangements with the Trust.

In connection with their contract review meetings, the Trustees received and
relied upon materials which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of each Series for various
time periods ended December 31, 2004, compared to the investment performance of
a group of funds with substantially similar investment
classifications/objectives (the "Lipper performance universe"), as well as the
investment performance of a group of funds identified by objective criteria
suggested by MFS ("peer funds"), (ii) information provided by Lipper Inc. on
each Series' advisory fees and other expenses compared to the advisory fees and
other expenses of comparable funds identified by Lipper (the "Lipper expense
group"), as well as the advisory fees and other expenses of peer funds
identified by objective criteria suggested by MFS, (iii) information provided by
MFS on the advisory fees of comparable portfolios of its other clients,
including institutional separate account and other clients, (iv) information as
to whether, and to what extent applicable, expense waivers, reimbursements or
fee "breakpoints" are observed for a Series, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Series, (vi)
MFS' views regarding the outlook for the mutual fund industry and its strategic
business plans, (vii) descriptions of various functions performed by MFS for the
Trust, such as compliance monitoring and portfolio trading practices, and (viii)
information regarding the overall organization of MFS, including information
about MFS' senior management and other personnel providing investment advisory,
administrative and other services to the Series. The comparative performance,
fee and expense information prepared and provided by Lipper Inc. was not
independently verified, and the independent Trustees did not independently
verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreements was based on comprehensive consideration of all information provided
to the Trustees and not the result of any single factor. Some of the factors
that figured particularly in the Trustees' deliberations are described below for
each Series, while individual Trustees may have given different weight to
various factors and evaluated the information presented as a whole differently
than another Trustee. The Trustees recognized that the fee arrangements for the
Series reflect years of review and discussion between the independent Trustees
and MFS, that certain aspects of such arrangements may receive greater scrutiny
in some years than others, and that the Trustees' conclusions may be based, in
part, on their consideration of these same arrangements during the course of the
year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees compared each
Series' total return investment performance to the performance of peer groups of
funds over various time periods. The Trustees placed particular emphasis on the
total return performance of each Series' Initial Class shares in comparison to
the performance of funds in its Lipper performance universe over the one-,
three- and five-year periods. The Trustees did not rely on performance results
for more recent periods, including those shown elsewhere in this report.

In the course of their deliberations, the Trustees took into account information
provided by MFS during contract review meetings, as well as during investment
review meetings conducted with portfolio management personnel during the course
of the year. For Series whose performance lagged their peer groups, they
discussed MFS' efforts to improve such Series' performance. After reviewing this
information, the Trustees concluded, within the context of their overall
conclusions regarding the investment advisory agreements, that they were
satisfied with MFS' responses and efforts relating to investment performance.

In assessing the reasonableness of each Series' advisory fee, the Trustees
considered, among other information, each Series' advisory fee and the total
expense ratio of the Series' Initial Class shares as a percentage of average net
assets, compared to the advisory fee and total expense ratios of peer groups of
funds based on information provided by Lipper Inc. and MFS. The Trustees also
considered the advisory fees charged by MFS to institutional accounts. In
comparing these fees, the Trustees considered the generally broader scope of
services provided by MFS to the Trust than those provided to institutional
accounts. The Trustees also considered the higher demands placed on MFS'
investment personnel and trading infrastructure as a result of the daily cash
in-flows and out-flows of the Series, and the impact on MFS and related expenses
due to the more extensive regulatory regime to which the Series are subject,
compared to institutional accounts.

The Trustees also considered whether a Series is likely to benefit from any
economies of scale due to future asset growth. In this regard, the Trustees
reviewed the adequacy of breakpoints, and considered if breakpoints should be
implemented for any Series that did not have them.

The Trustees also considered information prepared by MFS relating to its costs
and profits with respect to the Series and other investment companies and
accounts advised by MFS, as well as MFS' methodologies used to determine and
allocate its costs to the Series and other accounts and products for purposes of
estimating profitability.

After reviewing these and other factors described below, the Trustees concluded
that the advisory fees charged to the Series represent reasonable compensation
in light of the nature and quality of the services being provided by MFS.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Series.
The Trustees also considered the financial resources of MFS and its affiliation
with Sun Life Financial Inc. The Trustees further considered any advantages and
possible disadvantages of having an adviser which also serves other investment
companies as well as institutional accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the
Series by MFS and its affiliates under agreements and plans other than the
investment advisory agreements, including the 12b-1 fees the Series pay to MFS
Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges on
the Series' behalf, including securities lending programs, directed expense
payment programs, class action recovery programs, and MFS' interaction with
third-party service providers, principally custodians and sub-custodians. The
Trustees concluded that the various non-advisory services provided by MFS and
its affiliates on behalf of the Series were satisfactory. The Trustees also
considered the benefits to MFS from the use of the Series' portfolio brokerage
commissions to pay for research and other similar services (including MFS'
current policy not to use "soft dollars" generated by Series portfolio
transactions to pay for third-party research), and various other factors.
Additionally, the Trustees considered so-called "fall-out benefits" to MFS such
as reputational value derived from serving as investment manager to the Trust,
and determined that any such benefits derived by MFS were reasonable and fair.

Based on their evaluation of factors that they deemed to be material,
including those factors described above, and the individual Series factors
noted below, the Board of Trustees, including a majority of the independent
Trustees, concluded that the investment advisory agreements should be
continued for an additional one-year period, commencing September 1, 2005.

BOND SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 10th percentile relative to the other funds in the Lipper
Classification Index for the one-year period (the 1st percentile being the best
performers and the 100th percentile being the worst performers). The total
return performance of the Series was in the 12th percentile for the three-year
period and the 11th percentile for the five-year period ended December 31, 2004,
relative to the Lipper performance universe. Based on the nature and quality of
services provided by MFS, the Board of Trustees concluded that the Series'
performance was satisfactory.

In considering the fees, the Trustees noted from the Lipper data that the
Series' effective advisory fee rate was higher than, and total expense ratio was
approximately at, the median of such fees and expenses of funds in the Lipper
expense group. They further noted that the Series' advisory fee rate schedule is
not currently subject to any breakpoints. In light of the relatively small size
of the Series, the Trustees concluded the fees were satisfactory without
implementing breakpoints.

EMERGING MARKETS EQUITY SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 18th percentile relative to the other funds in the Lipper

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 total return performance of the Series' Initial Class
shares was in the 38th percentile relative to the other funds in the Lipper
Classification Index for the one-year period (the 1st percentile being the best

return performance of the Series was in the 35th percentile for the three-year
and five-year periods ended December 31, 2004, relative to the Lipper

voluntary expense limitation for the Series, which may not be changed without
the Trustees' approval. The Trustees noted from the Lipper data that the Series'
effective advisory fee rate and total expense ratio were each approximately at
the median of such fees and expenses of funds in the Lipper expense group. The
Trustees further concluded that the existing breakpoints were sufficient to
allow the Series to benefit from economies of scale as its assets grow. The
Trustees concluded that the fees were reasonable in light of the nature and
quality of services provided.

GLOBAL TOTAL RETURN SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 7th percentile relative to the other funds in the Lipper
Classification Index for the one-year period (the 1st percentile being the best
performers and the 100th percentile being the worst performers). The total
return performance of the Series was in the 24th percentile for the three-year
period and the 10th percentile for the five-year period ended December 31, 2004,

shares was in the 39th percentile relative to the other funds in the Lipper
Classification Index for the one-year period (the 1st percentile being the
best performers and the 100th percentile being the worst performers). The
total return performance of the Series was in the 45th percentile for the

the request of the Trustees, MFS agreed to implement an advisory fee
contractual breakpoint to reduce the Series' annual advisory fee rate by 0.05%
on net assets over $1 billion, which took

LETTER FROM THE CEO OF MFS

DEAR CONTRACT OWNERS,

Most investors are familiar with the basic principles of investing - focus on
the long term and keep your assets diversified across different investment
categories. Still, it is surprising how often we forget these basic lessons.
Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s
had many people hoping they could become millionaires overnight. But the
market decline that started in the spring of 2000 taught everyone how
misguided those hopes had been.

Now, less than six years after the market taught a harsh lesson in the follies
of speculative investing, we are seeing a number of trends that suggest many
investors, including professionals, are hoping for overnight miracles again.
We see a steady stream of market "gurus" on television news shows, promising
to teach amateur investors the strategies that will allow them to get rich
quick. Hedge funds - which by their nature move in and out of investments
rapidly - have soared in popularity in recent years. We are reminded every day
that we live in a "what have you done for me lately?" world, but this mindset
should not influence how we invest and manage our money. In fact, investors
often fall short of their goals because they traded in and out of investments
too frequently and at inopportune times.

Throughout our more than 80-year history, MFS' money management process has
focused on long-term investment opportunities. We firmly believe that the best
way to realize long-term financial goals - be it a college education, a
comfortable retirement, or a secure family legacy - is to follow a three-
pronged approach that focuses on longer time horizons. Allocate holdings
across the major asset classes - including stocks, bonds, and cash. Diversify
within each class to take advantage of different market segments and investing
styles. And rebalance assets regularly to maintain a desired asset
allocation.* This long-term approach requires diligence and patience, two
traits that in our experience are essential to capitalizing on the many
opportunities the financial markets can offer.

    Respectfully,

/s/ Robert J. Manning

    Robert J. Manning
    Chief Executive Officer and Chief Investment Officer
    MFS Investment Management(R)

    February 15, 2006

* Asset allocation, diversification, and rebalancing do not guarantee a profit
  or protect against a loss. The opinions expressed in this letter are those of
  MFS, and no forecasts can be guaranteed.

MANAGEMENT REVIEWS

CAPITAL APPRECIATION SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 0.92%, while Service Class shares provided a
total return of 0.63%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 5.26% for the series'
benchmark, the Russell 1000 Growth Index.

DETRACTORS FROM PERFORMANCE

The technology sector was the largest detractor from relative performance over
the period. Poor stock selection was the primary reason for relative
underperformance within the sector. Our holdings in printer products
manufacturer Lexmark International*, security software firm Symantec, and
networking and communications manufacturer Cisco Systems held back results as
these stocks underperformed the index over the reporting period.
Underweighting computer manufacturer Apple Computer* also weighed on relative
results.

No individual stocks within the leisure sector were among the portfolio's top
detractors.

Security selection in the industrial goods and services and retailing sectors
also dampened results. In industrial goods and services, manufacturing
conglomerate Tyco International (not an index constituent) weakened
performance. In retailing, online retailer and services provider IAC/
InterActiveCorp* held back results.

Elsewhere, holdings in motorcycle manufacturer Harley-Davidson* and biotech
firm ImClone Systems* hampered results. Our virtual avoidance of drug maker
Pfizer*, which outperformed during the period, also held back performance.

The portfolio's cash position was also a detractor from relative performance.
The portfolio holds cash to buy new holdings and to provide liquidity. In a
period when equity markets rose, as measured by the portfolio's benchmark,
holding cash hurt performance versus the benchmark, which has no cash
position.

CONTRIBUTORS TO PERFORMANCE

Stock selection and an underweighted position in the financial services
sector, which underperformed the index, added to relative results. No
individual stocks within the sector were among the portfolio's top
contributors.

Stock selection in the basic materials sector helped relative results. Within
the sector, Brazilian iron ore miner Companhia Vale do Rio Doce* (not an index
constituent) contributed to performance.

Overweighting the energy sector and strong stock selection in the health care
sector also boosted relative performance. In energy, oil and gas supplier
Tenaris* (not an index constituent) aided results. In health care, our
holdings in biotech firm Amgen, pharmaceutical and diagnostic company Roche
Holding (not an index constituent), and hospital operators HCA* and Community
Health Systems* proved favorable.

Other individual stocks that contributed to relative performance included drug
store chain CVS and microchip and electronics manufacturer Samsung Electronics
(not an index constituent). Additionally, not owning International Business
Machine (IBM) and underweighting industrial conglomerate General Electric
enhanced relative results as both stocks performed poorly relative to the
overall index over the period.

* Security was not held in the portfolio at period-end.

EMERGING GROWTH SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 9.14%, while Service Class shares provided a
total return of 8.90%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 5.17% for the series'
benchmark, the Russell 3000 Growth Index.

CONTRIBUTORS TO PERFORMANCE

Over the period, the financial services, health care, and technology sectors
boosted results. In each case, the primary driver was strong stock selection.
In financial services, investment management firm Legg Mason and commodities
exchange Chicago Mercantile Exchange Holdings were among the top contributors
to relative performance. Despite its positive contribution to relative
performance, no individual stocks within the health care sector were among the
portfolio's top contributors.

In technology, our holdings in Internet search engine Google, maker of flash
memory storage products SanDisk, and South Korean microchip and electronics
manufacturer Samsung Electronics (not an index constituent) proved beneficial
to relative performance. Not holding weak-performing International Business
Machines (IBM) also helped relative results.

The portfolio's overweighted position in the utilities and communications
sector bolstered results as the sector outperformed the overall index.
Broadcast and communications operator American Tower and Latin American
wireless communications company America Movil (not an index constituent) were
among the portfolio's top relative contributors.

Other individual contributors to performance included drilling rig operator
GlobalSantaFe, which is not held in the index, and media image provider Getty
Images.

DETRACTORS FROM PERFORMANCE

Stock selection and, to a lesser extent, an overweighted position in the
leisure sector detracted from relative performance. Video games maker
Electronic Arts was among the portfolio's top detractors over the period.
Stock selection in the industrial goods and services and autos and housing
sectors also held back results. No individual stocks in the industrial goods
and services sector were among the top detractors. In autos and housing, sleep
products manufacturer Tempur-Pedic International* dampened relative
performance.

While no individual stocks in the special products and services sector were
among the portfolio's top detractors during the period, our overweighted
position in this sector hampered performance as the sector underperformed the
benchmark.

Elsewhere, our holdings in network security software company Symantec* and
software provider Mercury Interactive* hurt returns.

In health care, dermatological treatment company Medicis Pharmaceutical*,
biotech firms ImClone Systems and Genentech, and health care service provider
UnitedHealth Group negatively affected relative performance. Not holding
pharmaceutical company Pfizer also proved disappointing as the stock performed
better than the overall index during the period. In retailing, discount store
Family Dollar Stores* hindered relative results.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

* Security was not held in the portfolio at period-end.

GLOBAL GROWTH SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 10.03% while Service Class shares provided a
total return of 9.65%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 11.16% for the series'
benchmark, the MSCI All Country World Growth Index. The series' other
benchmark, the MSCI World Growth Index, provided a return of 9.74%.

DETRACTORS FROM PERFORMANCE

Although our relative underweighting in the technology sector aided results,
this was more than offset by security selection in this sector. Our positions
in network security software company Symantec, which is not a benchmark
constituent, and computer company Dell* hurt relative returns. Not owning
strong-performing index constituents Apple Computer and Google also hindered
results as both stocks more than doubled over the period.

The financial services and energy sectors also held back results, although no
individual holdings in either sector were among the portfolio's top relative
detractors. In other sectors, pay-television operator Premiere*, home
improvement retailer Kingfisher*, apparel retailer NEXT, and biotech firm
ImClone Systems*, which is not a benchmark constituent, dampened performance.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

CONTRIBUTORS TO PERFORMANCE

Stock selection in the consumer staples, industrial goods and services, and
retailing sectors contributed to the portfolio's relative performance over the
period. Our positions in strong-performing Brazilian brewer Companhia de
Bebidas das Americas* and convenience store operator 7-Eleven*, which is not a
benchmark constituent, boosted relative results in the consumer staples and
the retailing sectors, respectively. No individual holdings in the industrial
goods and services sector were among the portfolio's top contributors.

Elsewhere, our holdings in petrochemical company Reliance Industries, metal
miner Companhia Vale do Rio Doce, and global cement producer Cemex* aided
portfolio results. Avoiding benchmark constituent International Business
Machines (IBM) also helped as shares declined over the year. Other stocks that
contributed to performance included consumer finance company AEON Credit
Service, generic drug manufacturer Teva Pharmaceutical Industries, oil and gas
company Talisman Energy, and electronics manufacturer Samsung Electronics.

* Security was not held in the portfolio at period-end.

MASSACHUSETTS INVESTORS TRUST SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 7.70%, while Service Class shares provided a
total return of 7.42%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 4.91% for the series'
benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index).

CONTRIBUTORS TO PERFORMANCE

During the period, the energy, financial services, and health care sectors
contributed to relative performance. Security selection was the primary driver
of positive relative returns. In energy, oil field services provider
Halliburton, exploration and production company EOG Resources, offshore
drilling companies Noble Corp. and Transocean, and Canadian oil and gas
company EnCana, which is not an index constituent, contributed to relative
performance.

In financial services, investment management firm Legg Mason (not an index
constituent) aided relative results. In health care, our holdings in biotech
firm Gilead Sciences proved beneficial.

Other individual contributors over the period included personal computer maker
Apple Computer and agrichemical products manufacturer Monsanto. Our avoidance
of computer products and services provider International Business Machines
(IBM), was also favorable to relative performance, as the stock declined early
in the period.

DETRACTORS FROM PERFORMANCE

The utilities and communications sector detracted from relative performance
over the period. U.K.-based wireless phone services provider Vodafone Group
(not an index constituent) held back relative results. Although the
transportation and special products and services sectors also hurt results, no
individual stocks within these sectors were among the top detractors of the
portfolio.

Elsewhere, pharmaceutical company Abbott Laboratories and orthopedic products
designer and marketer Zimmer Holdings hurt the portfolio's relative
performance. Also, not holding oil and gas company ExxonMobil hampered results
as the stock performed better than the benchmark.

Stocks in other sectors that detracted from results included manufacturing
conglomerate Tyco International, direct-sale computer vendor Dell, home
improvement products maker Masco, video games maker Electronic Arts, cosmetics
and beauty supply company Avon*, and enterprise software giant Oracle.

During the reporting period, the portfolio's currency exposure was a detractor
from the portfolio's relative performance. All of MFS' investment decisions
are driven by the fundamentals of each individual opportunity and, as such, it
is common for our portfolios to have different currency exposure than the
benchmark.

* Security was not held in the portfolio at period-end.

MID CAP GROWTH SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 3.10%, while Service Class shares provided a
total return of 2.78%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 12.10% for the series'
benchmark, the Russell Midcap Growth Index.

DETRACTORS FROM PERFORMANCE

The retailing, technology, and leisure sectors were the largest detractors
from relative performance over the period. In all three sectors, stock
selection dampened investment results.

Several individual securities in the technology sector significantly hurt
results including network security software company Symantec, which is not a
benchmark constituent, business software company Mercury Interactive*, and
semiconductor manufacturers PMC-Sierra and Xilinx.

In the leisure sector, radio broadcasting firm Citadel Broadcasting, media
company Gemstar-TV Guide*, and cruise line operator Royal Caribbean Cruises*,
which is not a benchmark constituent, held back results relative to the
benchmark.

No individual stocks within the retailing sector were among the portfolio's
top detractors.

Other stocks that hurt performance included for-profit education company
Apollo Group, which is not an index constituent, dermatological treatment
company Medicis Pharmaceutical, and biotech firm ImClone Systems.

CONTRIBUTORS TO PERFORMANCE

Stock selection in the financial services sector boosted relative performance
as our holdings in investment management firm Legg Mason significantly
outperformed the benchmark over the period.

Results were aided by our overweighted position in the strong-performing
utilities and communications sector. Within this sector, broadcast and
communication tower management firm American Tower was the top contributor.

Elsewhere, in technology, networking chip maker Marvell Technology Group,
which is not a benchmark constituent, and flash memory storage products maker
SanDisk bolstered results. Our positioning in multimedia and publishing
software company Adobe Systems also contributed as we added the stock to the
portfolio prior to a run-up in share price.

In health care, our holdings in biotech firm Gilead Sciences and medical
device company Thoratec, neither of which are benchmark constituents, and non-
urban hospital operator Community Health Systems* were among the portfolio's
top contributors.

Other individual holdings that benefited portfolio performance included
drilling rig operator GlobalSantaFe, which is not a benchmark constituent, and
multimedia image provider
Getty Images.

* Security was not held in the portfolio at period-end.

RESEARCH SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 7.94% while Service Class shares provided a
total return of 7.71%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 4.91% for the series'
benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index).

CONTRIBUTORS TO PERFORMANCE

Stock selection in the financial services sector boosted relative performance
as our holdings in investment management firm Legg Mason, which is not a
benchmark constituent, significantly outperformed the benchmark over the
period. Other stocks in this sector that positively impacted results included
investment manager Franklin Resources and investment banking firm Goldman
Sachs Group.

Security selection in the energy sector also contributed to performance. Our
holdings in drilling rig operator GlobalSantaFe, which is not a benchmark
constituent, was the top contributing stock within this sector. Other energy
stocks that benefited relative results included offshore drilling company
Noble Corp., oil field services provider Halliburton*, and French integrated
oil company TOTAL, which is not an index constituent.

Although the portfolio benefited from strong stock selection in the special
products and services sector, no individual stocks within this sector were
among the portfolio's top contributors. Stocks in other sectors that aided
performance included flash memory storage products maker SanDisk, multimedia
image provider Getty Images, and drug-maker Endo Pharmaceuticals Holdings,
none of which are benchmark constituents.

DETRACTORS FROM PERFORMANCE

The technology sector was the largest relative detractor as stock selection
within this sector held back results. Our holdings in network security
software company Symantec* and computer company Dell proved disappointing as
shares of both stocks declined over the period. Additionally, not owning
strong-performing benchmark constituent Apple Computer was a drag on relative
returns as the stock more than doubled over the year.

The autos and housing and basic materials sectors also hurt results. In autos
and housing, our positions in home improvement products maker Masco and
motorcycle manufacturer Harley-Davidson* hindered results, while in basic
materials, newsprint maker Bowater, which is not an index constituent, was
among the top detractors. Elsewhere, biotechnology firm ImClone, apparel
retailer Gap, and hospital operator Tenet Healthcare* dampened performance.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

* Security was not held in the portfolio at period-end.

TOTAL RETURN SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 3.02%, while Service Class shares provided a
total return of 2.81%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 4.91% for the series'
benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index).
The series' other benchmark, the Lehman Brothers U.S. Aggregate Bond Index,
provided a return of 2.43%.

DETRACTORS FROM PERFORMANCE

Within the equity portion of the series, security selection in the utilities
and communications sector detracted from relative performance. Overweighted
positions in independent power producer Calpine* and telecom services provider
Verizon Communications held back returns as both stocks lagged the S&P 500
Stock Index.

Security selection within the basic materials sector also weighed on results.
During the period, the portfolio's holdings in newsprint maker Bowater (not an
S&P 500 Stock Index constituent) hurt relative performance.

A combination of an overweighted position and stock selection within the
leisure sector held back investment results. Overweighting poor-performing
global entertainment conglomerate Viacom negatively impacted the portfolio's
relative performance.

Elsewhere, holdings in health care firm Tenet Healthcare hurt results as the
stock underperformed the S&P 500 Stock Index. In technology, positions in
network security firm Symantec and telecom equipment company Nortel Networks
(not an S&P 500 Stock Index constituent), and the avoidance of strong-
performing Apple Computer, detracted from relative performance. Overweighting
home improvement firm Masco (in the autos and housing sector) and retailer Gap
also held back returns.

During the reporting period, currency exposure within the equity portion of
the series was a detractor from relative performance. All of MFS' equity
investment decisions are driven by the fundamentals of each individual
opportunity and, as such, it is common for our portfolios to have different
currency exposure than the benchmark.

Within the fixed income portion of the series, overweighting "BBB"-rated(1)
securities held back performance relative to the Lehman Brothers U.S.
Aggregate Bond Index. During the period, spreads on "BBB"-rated debt widened,
causing bonds within this quality sector to lose value. Specific sectors that
detracted from performance included finance and agency-related debt. In the
finance sector, bonds of Ford Motor Credit and General Motors Acceptance Corp
hurt returns.

CONTRIBUTORS TO PERFORMANCE

Within the equity portion of the series, a combination of an overweighted
position and positive security selection within the strong-performing energy
sector boosted performance relative to the S&P 500 Stock Index. Overweighting
a number of energy firms contributed to the portfolio's relative results,
including oil and gas producer Devon Energy, energy exploration and production
company EOG Resources, and offshore drilling company Noble Corp. Positions in
drilling rig operator GlobalSantaFe and oil and gas service company Cooper
Cameron, neither of which are S&P 500 Stock Index constituents, also helped.

A combination of stock selection and, to a lesser extent, the portfolio's
overweighting in the financial services sector contributed to relative results
over the period. Although financial services was a top contributing sector on
a relative basis, no individual securities within the sector were among the
portfolio's top contributors. An overweighted position and positive security
selection within the special products and services sector also aided results.
Avoiding poor-performing Internet auctioneer eBay benefited returns as the
stock underperformed the S&P 500 Stock Index over the period.

Elsewhere, underweighting information technology firm International Business
Machines (IBM) and computer manufacturer Dell* in the technology sector added
to relative performance. In health care, underweighting weak-performing
pharmaceutical giant Pfizer* also boosted results. In the industrial goods and
services sector, overweighting aerospace and defense firm Lockheed Martin
proved beneficial to performance as the stock outperformed the S&P 500 Stock
Index.

Within the fixed income portion of the series, the stance on duration(2) aided
performance relative to the Lehman Brothers U.S. Aggregate Bond Index. During
the period, the portfolio maintained a shorter duration than the index.
Holdings of Treasury securities bolstered performance over the period as did
the portfolio's positioning in mortgage-backed and asset-backed securities.

* Security was not held in the portfolio at period-end.

UTILITIES SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 17.23%, while Service Class shares provided
a total return of 16.97%. These returns do not reflect any applicable contract
or surrender charges and compare with a return of 16.84% for the series'
benchmark, the Standard & Poor's 500 Utilities Index.

CONTRIBUTORS TO PERFORMANCE

Strong stock selection in the electric power industry contributed to the
portfolio's relative returns for the period. Within this industry, wholesale
power generator NRG Energy and Brazilian electricity provider CPFL Energia,
neither of which are benchmark constituents, were among the portfolio's top
contributors. Additionally, not holding electric power companies Southern
Company, independent power producer Calpine, and Progress Energy (all
benchmark constituents which lagged overall benchmark returns) aided relative
performance.

Our positions in the oil service industry, which is not represented in the
index, bolstered results. Oil field services provider Halliburton contributed
positively to the portfolio's relative performance over the period.

Stock selection in the natural gas distribution industry also boosted relative
performance. Our position in Questar, which is not a benchmark constituent,
helped performance as the stock value appreciated significantly over the
period. Not owning weak-performing benchmark constituent KeySpan also proved
favorable.

Elsewhere, our holdings in Mexican wireless communications company America
Movil and Brazilian oil and gas exploration and production company Petroleo
Brasileiro, neither of which are benchmark constituents, also had a positive
impact on the portfolio's relative results.

DETRACTORS FROM PERFORMANCE

Holdings in the telephone services industry hurt relative results. Several
stocks within this industry, which is not represented in the index, were among
the portfolio's greatest individual detractors. These included wireless
services companies Sprint Nextel, Deutsche Telekom*, and Telefonica*.

Our positions in the broadcast and cable television industry, which is not
represented in the index, also hindered relative performance. Among the
portfolio's top detractors were media and entertainment company News Corp,
cable services provider Comcast, and media giant Viacom.

Although the electric power industry contributed to relative performance, our
underweighted positions in several strong-performing benchmark constituents
detracted from results. These included TXU, Public Service Enterprise Group*,
and FirstEnergy. Our holdings in wireless communications provider Vodafone
Group, which is not a benchmark constituent, also held back relative returns.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity, and as such, it is common for our
portfolios to have different currency exposure than the benchmark.

NOTES TO PERFORMANCE SUMMARY

Initial Class shares have no sales charge. Service Class shares have no sales
charge and carry a 0.25% annual Rule 12b-1 fee.

Service Class share performance includes the performance of Initial Class
shares for periods prior to the inception of Service Class shares (blended
performance). These blended performance figures have not been adjusted to take
into account differences in the class-specific operating expenses (such as
Rule 12b-1 fees). Because operating expenses of Service Class shares are
generally higher than those of Initial Class shares, the blended Service Class
shares performance shown is higher than it would have been had Service Class
shares been offered for the entire period.

Performance results reflect any applicable expense subsidies and waivers in
effect during the periods shown; without these the results would have been
less favorable. See the prospectus for details. All results are historical and
assume the reinvestment of any dividends and capital gains distributions.

The returns for the series shown do not reflect the deduction of expenses
associated with variable products, such as mortality and expense risk charges,
separate account charges, and sales charges imposed by insurance company
separate accounts. Such expenses would reduce the overall returns shown.

From time to time the series may receive proceeds from litigation settlements,
without which performance would be lower.

KEY RISK CONSIDERATIONS

CAPITAL APPRECIATION SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments.

EMERGING GROWTH SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Changes in currency exchange rates may
affect the portfolio's net asset value, the value of dividends and interest
earned, and gains and losses realized on the sale of securities. Growth stocks
may perform differently from the general stock market and can be more volatile
than other types of stocks.

GLOBAL GROWTH SERIES

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

MASSACHUSETTS INVESTORS TRUST SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments.

MID CAP GROWTH SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. The securities of medium size
companies may be more volatile than those of larger companies. Growth stocks
may perform differently from the general stock market and can be more volatile
than other types of stocks.

RESEARCH SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments.

TOTAL RETURN SERIES

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

UTILITIES SERIES

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

When you sell units, they may be worth more or less than the amount you paid
for them.

Please see the prospectus for further information regarding these and other
risks considerations.


EXPENSE TABLES
SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD,
JULY 1, 2005 THROUGH DECEMBER 31, 2005

As a shareholder of the series, you incur ongoing costs, including management
fees; distribution (12b-1) fees; and other series expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing
in the series and to compare these costs with the ongoing costs of investing
in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period, July 1, 2005 through December 31,
2005.

ACTUAL EXPENSES
The first line for each share class in the following tables provides
information about actual account values and actual expenses. You may use the
information in this line, together with the amount you invested, to estimate
the expenses that you paid over the period. Simply divide your account value
by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number in the first line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your
account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line for each share class in the following tables provides
information about hypothetical account values and hypothetical expenses based
on the series' actual expense ratio and an assumed rate of return of 5% per
year before expenses, which is not the series' actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the series and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight the
series' ongoing costs only and do not take into account the fees and expenses
imposed under the variable contracts through which your investment in the
series is made. Therefore, the second line for each share class in the tables
is useful in comparing ongoing costs associated with an investment in vehicles
(such as the series) which fund benefits under variable annuity and variable
life insurance contracts and to qualified pension and retirement plans only,
and will not help you determine the relative total costs of investing in the
series through variable annuity and variable life insurance contracts. If the
fees and expenses imposed under the variable contracts were included, your
costs would have been higher.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or
life of a particular 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.

(a) Annualized.

(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.
(i) For the period from the class' inception, August 24, 2001 (Service Class) through the stated period end.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. The
    non-recurring accrual 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 been lower by approximately 0.11%.
(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.
(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing
    of sales of series shares and the amount of per share realized and unrealized gains and losses at such time.

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

(a) Annualized.
(n) Not annualized.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.
(i) For the period from the class' inception, August 24, 2001 (Service Class) through the stated period end.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. The
    non-recurring accrual did not have a material impact on the net asset value per share based on shares outstanding on the day
    the proceeds were recorded.
(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, total return for the
    year ended December 31, 2003 would have been 0.79% and 0.80% lower for the Initial Class and the Service Class shares,
    respectively.
(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing
    of sales of series shares and the amount of per share realized and unrealized gains and losses at such time.

MFS/SUN LIFE SERIES TRUST

FINANCIAL HIGHLIGHTS -- continued

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or life
of a particular 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.

(a) Annualized.
(n) Not annualized.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.
(i) For the period from the class' inception, August 24, 2001 (Service Class) through the stated period end.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. The
    non-recurring accrual 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.
(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%.
(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing
    of sales of series shares and the amount of per share realized and unrealized gains and losses at such time.

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or life
of a particular 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

(a) Annualized.
(n) Not annualized.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(s) From time to time the series may receive proceeds from litigation settlements, without which performance would be lower.
(i) For the period from the class' inception, August 24, 2001 (Service Class) through the stated period end.
(k) The total return does not reflect expenses that apply to separate accounts. Inclusion of these charges would reduce the total
    return figures for all periods shown.
(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. The
    non-recurring accrual 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.
(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%.
(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing
    of sales of series shares and the amount of per share realized and unrealized gains and losses at such time.

MFS/SUN LIFE SERIES TRUST

FINANCIAL HIGHLIGHTS -- continued

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (or life
of a particular 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.

FINANCIAL HIGHLIGHTS -- continued

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

MFS/SUN LIFE SERIES TRUST

NOTES TO FINANCIAL STATEMENTS

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

The series denoted with an asterisk above are included within these financial
statements.

(2) SIGNIFICANT ACCOUNTING POLICIES
General - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
and disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
Certain series can invest in foreign securities, including securities of
emerging market issuers. Investments in foreign securities are vulnerable to
the effects of changes in the relative values of the local currency and the
U.S. dollar and to the effects of changes in each country's legal, political,
and economic environment. The markets of emerging markets countries are
generally more volatile than the markets of developed countries with more
mature economies. All of the risks of investing in foreign securities
previously described are heightened when investing in emerging markets
countries.

Investment Valuations - Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported by an independent pricing service on the market or exchange on which
they are primarily traded. For securities for which there were no sales during
the day, equity securities are generally valued at the last quoted bid price
as reported by an independent pricing service on the market or exchange on
which they are primarily traded. Debt instruments (other than short-term
instruments), including restricted debt instruments, are generally valued at
an evaluated bid price as reported by an independent pricing service. Values
of debt instruments obtained from pricing services can utilize both dealer-
supplied valuations and electronic data processing techniques which take into
account factors such as institutional-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics and other market data. Short-term instruments with a maturity
at issuance of 365 days or less are generally valued at amortized cost, which
approximates market value. Forward foreign currency contracts are generally
valued at the mean of bid and asked prices based on rates reported by an
independent pricing service. Open-end investment companies are generally
valued at their net asset value per share. Securities and other assets
generally valued on the basis of information from an independent pricing
service may also be valued on the basis of information from brokers and
dealers. The values of foreign securities and other assets and liabilities
expressed in foreign currencies are converted to U.S. dollars based upon
exchange rates provided by an independent source. When pricing-service
information or market quotations are not readily available, securities are
priced at fair value as determined under the direction of the Board of
Trustees. For example, in valuing securities that trade principally on foreign
markets, events reasonably determined to be significant (such as certain
movements in the U.S. securities market, or other regional and local
developments) may occur between the time that foreign markets close (where the
security is principally traded) and the series' valuation time that may impact
the value of securities traded in these foreign markets. In these cases, the
series may utilize information from an external vendor or other sources to
adjust closing market prices of foreign equity securities to reflect what it
believes to be the fair value of the securities as of the series' valuation
time. Fair valuation of foreign equity securities may occur frequently based
on an assessment that events which occur on a fairly regular basis (such as
U.S. market movements) are significant.

Repurchase Agreements - Each series may enter into repurchase agreements with
institutions that the series' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. Each series
requires that the securities collateral in a repurchase transaction be
transferred to the custodian in a manner sufficient to enable the series to
obtain those securities in the event of a default under the repurchase
agreement. Each series monitors, on a daily basis, the value of the collateral
to ensure that its value, including accrued interest, is greater than amounts
owed to the series under each such repurchase agreement. Each series, along
with other affiliated entities of Massachusetts Financial Services Company
(MFS), may utilize a joint trading account for the purpose of entering into
one or more repurchase agreements.

Inflation-Adjusted Debt Securities - Certain series invest in inflation-
adjusted debt securities issued by the U.S. Treasury. Certain series may also
invest in inflation-adjusted debt securities issued by U.S. Government
agencies and instrumentalities other than the U.S. Treasury and by other
entities such as U.S. and foreign corporations and foreign governments. The
principal value of these debt securities is adjusted by references to changes
in the Consumer Price Index or another general price or wage index. These debt
securities typically pay a fixed rate of interest, but this fixed rate is
applied to the inflation-adjusted principal amount. The principal paid at
maturity of the debt security is typically equal to the inflation-adjusted
principal amount, or the security's original par value, whichever is greater.
Other types of inflation-adjusted securities may use other methods to adjust
for other measures of inflation.

Foreign Currency Translation - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of
both realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

Derivative Risk - Each series may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When each series uses derivatives as an investment
to gain market exposure, or for hedging purposes, gains and losses from
derivative instruments may be substantially greater than the derivative's
original cost. Derivative instruments include forward foreign currency
exchange contracts for the Utilities Series.

Forward Foreign Currency Exchange Contracts - Each series may enter into
forward foreign currency exchange contracts for the purchase or sale of a
specific foreign currency at a fixed price on a future date. Risks may arise
upon entering into these contracts from the potential inability of
counterparties to meet the terms of their contracts and from unanticipated
movements in the value of the contract. Each series may enter into forward
foreign currency exchange contracts for hedging purposes as well as for non-
hedging purposes. For hedging purposes, each series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. Each series may also use contracts in a manner
intended to protect foreign currency denominated securities from declines in
value due to unfavorable exchange rate movements. For non-hedging purposes,
each series may enter into contracts with the intent of changing the relative
exposure of the series' portfolio of securities to different currencies to
take advantage of anticipated changes. The forward foreign currency exchange
contracts are adjusted by the daily exchange rate of the underlying currency
and any gains or losses are recorded as unrealized until the contract
settlement date. On contract settlement date, the gains or losses are recorded
as realized gains or losses on foreign currency transactions.

Security Loans - State Street Bank and Trust Company ("State Street") and J.P.
Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of
certain series to certain qualified institutions (the "Borrowers") approved by
the series. The loans are collateralized at all times by cash and/or U.S.
Treasury securities in an amount at least equal to the market value of the
securities loaned. State Street and Chase provide certain series with
indemnification against Borrower default. Each series bears the risk of loss
with respect to the investment of cash collateral. On loans collateralized by
cash, the cash collateral is invested in a money market fund or short-term
securities. A portion of the income generated upon investment of the
collateral is remitted to the Borrowers, and the remainder is allocated
between the series and the lending agents. On loans collateralized by U.S.
Treasury securities, a fee is received from the Borrower, and is allocated
between the series and the lending agents. The dividend and interest income
earned on the securities loaned is accounted for in the same manner as other
dividend and interest income.

Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and discount is amortized or accreted for financial statement purposes in
accordance with U.S. generally accepted accounting principles. All discount is
accreted for tax reporting purposes as required by federal income tax
regulations. Dividends received in cash are recorded on the ex-dividend date.
Certain dividends from foreign securities will be recorded as soon as each
series is informed of the dividend if such information is obtained subsequent
to the ex-dividend date. Dividend and interest payments received in additional
securities are recorded on the ex-dividend or ex-interest date in an amount
equal to the value of the security on such date.

Each series may receive proceeds from litigation settlements involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss
in the Statements of Operations, or in unrealized gain/loss if the security is
still held by the series.

Fees Paid Indirectly - Certain series' custody fees are reduced according to
an arrangement that measures the value of cash deposited with the custodian by
the series. During the year ended December 31, 2005, certain series' custodian
fees were reduced under this arrangement as noted below. Each series has
entered into a commission recapture agreement, under which certain brokers
will credit the series a portion of the commissions generated, to offset
certain expenses of the series. For the year ended December 31, 2005, each
series' custodian expenses were reduced under this agreement as noted below.
These amounts are shown as a reduction of total expenses on the Statements of
Operations.

Tax Matters and Distributions - Each series intends to continue 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 generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share.
Temporary differences which arise from recognizing certain items of income,
expense, gain or loss in different periods for financial statements and tax
purposes will reverse at some time in the future. Distributions in excess of
net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income for financial statement and tax purposes.

Book/tax differences primarily relate to amortization and accretion of debt
securities, wash sale loss deferrals, foreign currency transactions,
derivative transactions, net operating losses and capital loss carryforwards,
which were assumed as a result of an acquisition.

The tax character of distributions declared to shareholders is as follows:

Multiple Classes of Shares of Beneficial Interest - Each series offers
multiple classes of shares, which differ in their respective distribution
fees. All shareholders bear the common expenses of the series based on daily
net assets of each class, without distinction between share classes. Dividends
are declared separately for each class. Differences in per share dividend
rates are generally due to differences in separate class expenses.

(3) TRANSACTIONS WITH AFFILIATES
Investment Adviser - Each series has an investment advisory agreement with MFS
to provide overall investment advisory and administrative services, and
general office facilities. The management fee is computed daily and paid
monthly at an annual rate based on a percentage of each series' average daily
net assets as follows:

Capital Appreciation Series: The management fee is 0.75% of the first $1
billion of average daily net assets, 0.675% of the next $500 million of
average daily net assets and 0.65% of average daily net assets in excess of
$1.5 billion.

Emerging Growth Series: The management fee is 0.75% of the first $300 million
of average daily net assets and 0.675% of average daily net assets in excess
of $300 million.

Global Growth Series: The management fee is 0.90% of the first $1 billion of
average daily net assets, 0.75% of the next $1 billion of average daily net
assets and 0.65% of average daily net assets in excess of $2 billion.

Massachusetts Investors Trust Series: The management fee is 0.55% of average
daily net assets.

Mid Cap Growth Series: Prior to September 1, 2005, the management fee was 0.75%
of the series' average daily net assets. Effective September 1, 2005, the
management fee is 0.75% of the first $1 billion of average daily net assets and
0.70% of average daily net assets in excess of $1 billion. The investment
adviser has contractually agreed to reduce its fee to 0.70% in excess of $500
million for the period September 1, 2005 through April 30, 2007. This reduction
of the management fee may be rescinded by MFS only with the approval of the
series' Board of Trustees.

Research Series: The management fee is 0.75% of the first $300 million of
average daily net assets and 0.675% of average daily net assets in excess of
$300 million.

Total Return Series: The management fee is 0.75% of the first $300 million of
average daily net assets, 0.675% of the next $700 million of average daily net
assets and 0.60% of average daily net assets in excess of $1 billion.

Utilities Series: The management fee is 0.75% of the first $300 million of
average daily net assets and 0.675% of average daily net assets in excess of
$300 million.

The investment adviser has agreed to pay a portion of certain series'
operating expenses, exclusive of certain other fees and expenses, such that
the operating expenses of these series do not exceed the expense limitations
indicated below, based on the average daily net assets of such series. The
management fees and expense limitations incurred for the year ended December
31, 2005 were equivalent to an annual effective rate of each series' average
daily net assets as follows:

Distributor - MFS Fund Distributors, Inc. (MFD), a wholly owned subsidiary of
MFS, is the distributor of shares of the series. The Trustees have adopted a
distribution plan for the Service Class shares pursuant to Rule 12b-1 under
the Investment Company Act of 1940.

The series' distribution plan provides that each series will pay MFD
distribution fees equal to 0.25% per annum of its average daily net assets
attributable to Service Class shares as partial consideration for services
performed and expenses incurred by MFD and financial intermediaries in
connection with the sale and distribution of the series' Service Class shares
and the sale and distribution of the variable annuity or variable life
insurance contracts investing indirectly in Service Class shares. MFD may
subsequently pay all, or a portion, of the distribution fees to financial
intermediaries.

Administrator - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to each series
and certain other MFS Funds (the funds) for which MFS acts as investment
adviser. Under an administrative services agreement, the funds may partially
reimburse MFS the costs incurred to provide these services, subject to review
and approval by the Board of Trustees. Each fund is allocated a
portion of these administrative costs based on its size and relative average
net assets. The administrative services fee incurred for the year ended
December 31, 2005 was equivalent to an annual effective rate of each series'
average daily net assets as follows:

                                                                     Percent of

Trustees' and Officers' Compensation - Each series pays compensation to
Independent Trustees in the form of a retainer, attendance fees, and
additional compensation to the Board chairperson. Each series does not pay
compensation directly to Trustees who are officers of the investment adviser,
or to officers of the series, all of whom receive remuneration for their
services to the series from MFS. Certain officers and Trustees of the series
are officers or directors of MFS, MFD, and MFS Service Center, Inc. (MFSC).

Other - The funds have entered into a services agreement (the Agreement) which
provides for payment of fees by the funds to Tarantino LLC in return for the
provision of services of an Independent Chief Compliance Officer (ICCO) for the
funds. The ICCO is an officer of the funds and the sole member of Tarantino
LLC. MFS has agreed to bear all expenses associated with office space, other
administrative support, and supplies provided to the ICCO. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement. For the year ended December 31, 2005, payments made by the series to
Tarantino LLC amounted to the following and are included in the miscellaneous
expense on the Statements of Operations:

                                                                       ICCO Fee

on disposition of a security in violation of the series' investment
restrictions. The amount of the gain was $70,344. This amount is separately
disclosed in the Statements of Changes in Net Assets. The effect of this gain
on the series' total return is disclosed in the Financial Highlights.

The series' investment adviser, MFS, was the subject of an administrative

(6) LINE OF CREDIT
Each series and other affiliated funds participate in a $1 billion unsecured
line of credit provided by a syndication of banks under a credit agreement.
Borrowings may be made for temporary financing needs. Interest is charged to
each series, based on its borrowings, at a rate equal to the Federal Reserve
funds rate plus 0.35%. In addition, a commitment fee, based on the average
daily, unused portion of the line of credit, is allocated among the
participating funds at the end of each calendar quarter. The commitment fee
allocated to each series for the year ended December 31, 2005 is included in
the miscellaneous expense on the Statements of Operations and is as follows
for each series:

                                                                 Commitment Fee

all of the assets and liabilities of Managed Sectors Series. The Managed
Sectors Series net assets on that date were $121,536,218, including
$10,518,687 of unrealized appreciation, $155,623 of accumulated net investment
loss, and $199,387,276 of accumulated net realized loss on investments and
foreign currency transactions. These assets were combined with those of the
series. The aggregate net assets of the Capital Appreciation Series after the
acquisition were $743,705,558.


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and the Shareholders of MFS/Sun Life Series Trust:

We have audited the accompanying statements of assets and liabilities,
including the portfolios of investments, of MFS/Sun Life Series Trust (the
"Trust"), comprising Capital Appreciation Series, Emerging Growth Series,
Global Growth Series, Massachusetts Investors Trust Series, Mid Cap Growth
Series, Research Series, Total Return Series and Utilities Series as of
December 31, 2005, and the related statements of operations for the year then
ended, the statements of changes in net assets for each of the two years in
the period then ended, and the financial highlights for each of the five years
in the period then ended. These financial statements and financial highlights
are the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Trust is not required to have, nor were we engaged to
perform, an audit of its internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Trust's internal control over financial reporting. Accordingly, we express no
such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. Our procedures
included confirmation of securities owned as of December 31, 2005, by
correspondence with the custodian and brokers; where replies were not received
from brokers, we performed other auditing procedures. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial positions of Capital
Appreciation Series, Emerging Growth Series, Global Growth Series,
Massachusetts Investors Trust Series, Mid Cap Growth Series, Research Series,
Total Return Series and Utilities Series as of December 31, 2005, the results
of their operations for the year then ended, the changes in their net assets
for each of the two years in the period then ended, and their financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States of America.

BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENTS

The Investment Company Act of 1940 requires that both the full Board of
Trustees and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Trust's investment
advisory agreements with Massachusetts Financial Services Company (MFS) on
behalf of the Series. The Trustees consider matters bearing on the Series and
their advisory arrangements at their meetings throughout the year, including a
review of performance data at each regular meeting. In addition, the
independent Trustees met several times over the course of three months
beginning in May and ending in July 2005 ("contract review meetings") for the
specific purpose of considering whether to approve the continuation of the
investment advisory agreements for the Series. The independent Trustees were
assisted in their evaluation of the investment advisory agreements by
independent legal counsel, from whom they received separate legal advice and
with whom they met separately from MFS management during various contract
review meetings. The independent Trustees were also assisted in this process
by the Series' Independent Chief Compliance Officer, a full-time senior
officer appointed by and reporting to the independent Trustees.

In connection with their deliberations, the Trustees, including the
independent Trustees, considered such information and factors as they
believed, in light of the legal advice furnished to them and their own
business judgment, to be relevant. The investment advisory agreements were
considered separately for each Series, although the Trustees also took into
account the common interests of all Series in their review. As described
below, the Trustees considered the nature, quality, and extent of the various
investment advisory, administrative, and shareholder services performed by MFS
under the existing investment advisory agreements and other arrangements with
the Trust.

In connection with their contract review meetings, the Trustees received and
relied upon materials which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of each Series for
various time periods ended December 31, 2004, compared to the investment
performance of a group of funds with substantially similar investment
classifications/objectives (the "Lipper performance universe"), as well as the
investment performance of a group of funds identified by objective criteria
suggested by MFS ("peer funds"), (ii) information provided by Lipper Inc. on
each Series' advisory fees and other expenses compared to the advisory fees
and other expenses of comparable funds identified by Lipper (the "Lipper
expense group"), as well as the advisory fees and other expenses of peer funds
identified by objective criteria suggested by MFS, (iii) information provided
by MFS on the advisory fees of comparable portfolios of its other clients,
including institutional separate account and other clients, (iv) information
as to whether, and to what extent applicable, expense waivers, reimbursements
or fee "breakpoints" are observed for a Series, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Series,
(vi) MFS' views regarding the outlook for the mutual fund industry and its
strategic business plans, (vii) descriptions of various functions performed by
MFS for the Trust, such as compliance monitoring and portfolio trading
practices, and (viii) information regarding the overall organization of MFS,
including information about MFS' senior management and other personnel
providing investment advisory, administrative and other services to the
Series. The comparative performance, fee and expense information prepared and
provided by Lipper Inc. was not independently verified, and the independent
Trustees did not independently verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreements was based on comprehensive consideration of all information
provided to the Trustees and not the result of any single factor. Some of the
factors that figured particularly in the Trustees' deliberations are described
below for each Series, while individual Trustees may have given different
weight to various factors and evaluated the information presented as a whole
differently than another Trustee. The Trustees recognized that the fee
arrangements for the Series reflect years of review and discussion between the
independent Trustees and MFS, that certain aspects of such arrangements may
receive greater scrutiny in some years than others, and that the Trustees'
conclusions may be based, in part, on their consideration of these same
arrangements during the course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees compared
each Series' total return investment performance to the performance of peer
groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of each Series' Initial Class shares
in comparison to the performance of funds in its Lipper performance universe
over the one-, three- and five-year periods. The Trustees did not rely on
performance results for more recent periods, including those shown elsewhere
in this report.

In the course of their deliberations, the Trustees took into account
information provided by MFS during contract review meetings, as well as during
investment review meetings conducted with portfolio management personnel during
the course of the year. For Series whose performance lagged their peer groups,
they discussed MFS' efforts to improve such Series' performance. After
reviewing this information, the Trustees concluded, within the context of their
overall conclusions regarding the investment advisory agreements, that they
were satisfied with MFS' responses and efforts relating to investment
performance.

In assessing the reasonableness of each Series' advisory fee, the Trustees
considered, among other information, each Series' advisory fee and the total
expense ratio of the Series' Initial Class shares as a percentage of average
net assets, compared to the advisory fee and total expense ratios of peer
groups of funds based on information provided by Lipper Inc. and MFS. The
Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered the generally
broader scope of services provided by MFS to the Trust than those provided to
institutional accounts. The Trustees also considered the higher demands placed
on MFS' investment personnel and trading infrastructure as a result of the
daily cash in-flows and out-flows of the Series, and the impact on MFS and
related expenses due to the more extensive regulatory regime to which the
Series are subject, compared to institutional accounts.

The Trustees also considered whether a Series is likely to benefit from any
economies of scale due to future asset growth. In this regard, the Trustees
reviewed the adequacy of breakpoints, and considered if breakpoints should be
implemented for any Series that did not have them.

The Trustees also considered information prepared by MFS relating to its costs
and profits with respect to the Series and other investment companies and
accounts advised by MFS, as well as MFS' methodologies used to determine and
allocate its costs to the Series and other accounts and products for purposes
of estimating profitability.

After reviewing these and other factors described below, the Trustees
concluded that the advisory fees charged to the Series represent reasonable
compensation in light of the nature and quality of the services being provided
by MFS.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the
Series. The Trustees also considered the financial resources of MFS and its
affiliation with Sun Life Financial Inc. The Trustees further considered any
advantages and possible disadvantages of having an adviser which also serves
other investment companies as well as institutional accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the
Series by MFS and its affiliates under agreements and plans other than the
investment advisory agreements, including the 12b-1 fees the Series pay to MFS
Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
on the Series' behalf, including securities lending programs, directed expense
payment programs, class action recovery programs, and MFS' interaction with
third-party service providers, principally custodians and sub-custodians. The
Trustees concluded that the various non-advisory services provided by MFS and
its affiliates on behalf of the Series were satisfactory. The Trustees also
considered the benefits to MFS from the use of the Series' portfolio brokerage
commissions to pay for research and other similar services (including MFS'
current policy not to use "soft dollars" generated by Series portfolio
transactions to pay for third-party research), and various other factors.
Additionally, the Trustees considered so-called "fall-out benefits" to MFS
such as reputational value derived from serving as investment manager to the
Trust, and determined that any such benefits derived by MFS were reasonable
and fair.

Based on their evaluation of factors that they deemed to be material,
including those factors described above, and the individual Series factors
noted below, the Board of Trustees, including a majority of the independent
Trustees, concluded that the investment advisory agreements should be
continued for an additional one-year period, commencing September 1, 2005.

CAPITAL APPRECIATION SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 19th percentile relative to the other funds in the
Lipper Classification Index for the one-year period (the 1st percentile
being the best performers and the 100th percentile being the worst
performers). The total return performance of the Series was in the 59th
percentile for the three-year period and the 62nd percentile for the five-
year period ended December 31, 2004, relative to the Lipper performance
universe. Based on the nature and quality of services provided by MFS and the
Series' improving performance, the Board of Trustees concluded that the
Series' performance was adequate.

In considering the fees, the Trustees noted that MFS currently observes a
voluntary expense limitation for the Series, which may not be changed without
the Trustees' approval. The Trustees noted from the Lipper data that the
Series' effective advisory fee rate and total expense ratio were each
approximately at the median of such fees and expenses of funds in the Lipper
expense group. The Trustees concluded that the existing breakpoints were
sufficient to allow the Series to benefit from economies of scale as its
assets grow. The Trustees concluded that the fees were reasonable in light of
the nature and quality of services provided.

EMERGING GROWTH SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 25th percentile relative to the other funds in the
Lipper Classification Index for the one-year period (the 1st percentile
being the best performers and the 100th percentile being the worst
performers). The total return performance of the Series was in the 75th
percentile for the three-year period and the 89th percentile for the five-
year period ended December 31, 2004, relative to the Lipper performance
universe. Based on the nature and quality of services provided by MFS and the
Series' improving performance, the Board of Trustees concluded that the
Series' performance was adequate.

In considering the fees, the Trustees noted that MFS currently observes a
voluntary expense limitation for the Series, which may not be changed without
the Trustees' approval. The Trustees noted from the Lipper data that the
Series' effective advisory fee rate and total expense ratio were each
approximately at the median of such fees and expenses of funds in the Lipper
expense group. The Trustees further concluded that the existing breakpoints
were sufficient to allow the Series to benefit from economies of scale as its
assets grow. The Trustees concluded that the fees were reasonable in light of
the nature and quality of services provided.

GLOBAL GROWTH SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 56th percentile relative to the other funds in the peer
universe for the one-year period (the 1st percentile being the best
performers and the 100th percentile being the worst performers). The total
return performance of the Series was in the 58th percentile for the three-
year period and the 63rd percentile for the five-year period ended
December 31, 2004, relative to the Lipper performance universe. The Trustees
noted the improved relative performance to the index since October 2003 when
the current portfolio management team was put fully in place. Based on the
nature and quality of services provided by MFS, and MFS' efforts to improve
performance, the Trustees concluded that the Series' performance was adequate.

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

MASSACHUSETTS INVESTORS TRUST SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 11th percentile relative to the other funds in the
Lipper Classification Index for the one-year period (the 1st percentile
being the best performers and the 100th percentile being the worst
performers). The total return performance of the Series was in the 37th
percentile for the three-year period and the 32nd percentile for the five-
year period ended December 31, 2004, relative to the Lipper performance
universe. Based on the nature and quality of services provided by MFS, the
Board of Trustees concluded that the Series' performance was satisfactory.

In considering the fees, the Trustees noted that MFS currently observes a
voluntary expense limitation for the Series, which may not be changed without
the Trustees' approval. The Trustees noted from the Lipper data that the
Series' effective advisory fee rate was lower than, and total expense ratio
was approximately at, the median of such fees and expenses of funds in the
Lipper expense group. They further noted that the Series' advisory fee rate
schedule is not currently subject to any breakpoints, but that the overall
advisory fee adequately reflected economies of scale. Accordingly, the
Trustees concluded that the fees were reasonable in light of the nature and
quality of services provided.

MID CAP GROWTH SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 50th percentile relative to the other funds in the
Lipper Classification Index for the one-year period (the 1st percentile
being the best performers and the 100th percentile being the worst
performers). The total return performance of the Series was in the 95th
percentile for the three-year period ended December 31, 2004, relative to the
Lipper performance universe. (The Series had been in existence for less than
five years.) Based on the nature and quality of services provided by MFS and
the Series' improving performance, the Board of Trustees concluded that the
Series' performance was adequate.

In considering the fees, the Trustees noted from the Lipper data that the
Series' effective advisory fee rate and total expense ratio were each lower
than the median of such fees and expenses of funds in the Lipper expense
group. They also noted that the Series' advisory fee rate schedule is not
currently subject to any breakpoints. Based on these considerations, at the
request of the Trustees, MFS agreed to implement an advisory fee contractual
breakpoint to reduce the Series' annual advisory fee rate by 0.05% on net
assets over $1 billion, which took effect on September 1, 2005, and MFS
further agreed to voluntarily reduce the breakpoint to $500 million through
April 30, 2007. The Trustees concluded that the fees were reasonable in light
of the nature and quality of services provided.

RESEARCH SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 18th percentile relative to the other funds in the
Lipper Classification Index for the one-year period (the 1st percentile
being the best performers and the 100th percentile being the worst
performers). The total return performance of the Series was in the 73rd
percentile for the three-year period and the 74th percentile for the five-
year period ended December 31, 2004, relative to the Lipper performance
universe. Based on the nature and quality of services provided by MFS and the
Series' improving performance, the Board of Trustees concluded that the
Series' performance was adequate.

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

TOTAL RETURN SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 4th percentile relative to the other funds in the Lipper
Classification Index for the one-year period (the 1st percentile being the

total return performance of the Series was in the 18th percentile for the
three-year period and the 7th percentile for the five-year period ended
December 31, 2004, relative to the Lipper performance universe. Based on the
nature and quality of services provided by MFS, the Board of Trustees
concluded that the Series' performance was satisfactory.

In considering the fees, the Trustees noted that MFS currently observes a
voluntary expense limitation for the Series, which may not be changed without
the Trustees' approval. The Trustees noted from the Lipper data that the
Series' effective advisory fee rate and total expense ratio were each higher
than the median of such fees and expenses of funds in the Lipper expense
group. The Trustees also concluded that the existing breakpoints were
sufficient to allow the Series to benefit from economies of scale as its
assets grow. The Trustees concluded that the fees were reasonable in light of
the nature and quality of services provided.

LETTER FROM THE CEO OF MFS

DEAR CONTRACT OWNERS,

Most investors are familiar with the basic principles of investing - focus on
the long term and keep your assets diversified across different investment
categories. Still, it is surprising how often we forget these basic lessons.
Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s
had many people hoping they could become millionaires overnight. But the
market decline that started in the spring of 2000 taught everyone how
misguided those hopes had been.

Now, less than six years after the market taught a harsh lesson in the follies
of speculative investing, we are seeing a number of trends that suggest many
investors, including professionals, are hoping for overnight miracles again.
We see a steady stream of market "gurus" on television news shows, promising
to teach amateur investors the strategies that will allow them to get rich
quick. Hedge funds - which by their nature move in and out of investments
rapidly - have soared in popularity in recent years. We are reminded every day
that we live in a "what have you done for me lately?" world, but this mindset
should not influence how we invest and manage our money. In fact, investors
often fall short of their goals because they traded in and out of investments
too frequently and at inopportune times.

Throughout our more than 80-year history, MFS' money management process has
focused on long-term investment opportunities. We firmly believe that the best
way to realize long-term financial goals - be it a college education, a
comfortable retirement, or a secure family legacy - is to follow a three-
pronged approach that focuses on longer time horizons. Allocate holdings across
the major asset classes - including stocks, bonds, and cash. Diversify within
each class to take advantage of different market segments and investing styles.
And rebalance assets regularly to maintain a desired asset allocation.* This
long-term approach requires diligence and patience, two traits that in our
experience are essential to capitalizing on the many opportunities the financial
markets can offer.

    Respectfully,

/s/ Robert J. Manning

    Robert J. Manning
    Chief Executive Officer and Chief Investment Officer
    MFS Investment Management(R)

    February 15, 2006

* Asset allocation, diversification, and rebalancing do not guarantee a profit
  or protect against a loss. The opinions expressed in this letter are those of
  MFS, and no forecasts can be guaranteed.

MANAGEMENT REVIEWS

CAPITAL OPPORTUNITIES SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 1.64%, while Service Class shares provided a
total return of 1.31%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 4.91% for the series'
benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index).

DETRACTORS FROM PERFORMANCE

Relative to the portfolio's benchmark, utilities and communications,
technology, and leisure were the portfolio's weakest-contributing sectors over
the period. In the utilities and communications sector, stock selection
detracted from relative returns. The portfolio's overweighted positions in
independent power producer Calpine* and telecom services provider Verizon*
were among the portfolio's top detractors for the period.

In the technology sector, stock selection was the principal detractor as well.
Holdings in network security software company Symantec and global telecom
equipment maker Nortel Networks, which is not a constituent of the benchmark,
held back relative returns.

Stock selection and an overweighted position in the leisure sector also dampened
investment results. Holdings in advertising and marketing services company
Interpublic Group* and media giant Viacom detracted from the portfolio's
relative returns.

Stocks in other sectors that had a negative impact on performance included
overweighted positions in poor-performing health services provider Tenet
Healthcare and manufacturing conglomerate Tyco International. The portfolio's
holdings in newsprint maker Bowater*, which is not a benchmark constituent, and
not holding strong-performing Apple Computer also hurt results.

During the reporting period, the portfolio's currency exposure detracted from
relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

CONTRIBUTORS TO PERFORMANCE

Health care, retailing, and financial services were the portfolio's top
contributing sectors over the period. Stock selection and an overweighted
position in the health care sector boosted relative results. Holdings in biotech
firm Gilead Sciences aided returns as the stock delivered strong performance.
Not holding poor-performing pharmaceutical company Pfizer, a constituent of the
benchmark, also helped.

Although retailing was a top contributing sector overall, no individual stocks
within the sector were among the portfolio's top contributors.

In financial services, our avoidance of mortgage financier Fannie Mae, whose
stock declined over the period, contributed to relative results.

Several stocks in the energy sector also helped performance. Overweighted
positions in drilling rig operator GlobalSantaFe and oil and gas equipment
manufacturer Cooper Cameron* (neither of which are benchmark constituents),
oil and gas producer Devon Energy, and offshore drilling company Noble Corp.
were among the portfolio's top contributors.

Holdings in strong-performing software developer Compuware*, diversified
technology company Corning*, and cell phone manufacturer Nokia, which is not a
benchmark constituent, also aided returns.

* Security was not held in the portfolio at period-end.

CORE EQUITY SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 6.56%, while Service Class shares provided a
total return of 6.39%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 4.91% for the series'
benchmark, the Standard & Poor's 500 Stock Index (the S&P 500 Stock Index).

CONTRIBUTORS TO PERFORMANCE

Over the reporting period, the health care, consumer staples, basic materials,
and utilities and communications sectors contributed to relative performance. In
each case, strong stock selection was the primary driver. In health care,
hospital operator HCA* and medical device maker Cyberonics* (not an index
constituent) boosted relative results. Not holding poor-performing
pharmaceutical giant Pfizer also proved favorable.

Despite positive contribution to relative return from the consumer staples
sector, no individual stocks within the sector were among the portfolio's top
contributors.

In basic materials, agrichemical products company Monsanto and Brazilian iron
ore miner Companhia Vale do Rio Doce (not an index constituent) were among the
portfolio's top contributors. Although strong stock selection also helped
relative returns in the utilities and communications sector, no individual
stocks within this sector were among the portfolio's top contributors.

Despite being a relative detractor, the technology sector included some of the
portfolio's top contributors. These included maker of flash memory storage
products SanDisk and business intelligence software firm MicroStrategy, neither
of which are benchmark constituents. Avoiding computer products and services
provider International Business Machines (IBM) for most of the reporting period,
during which the stock's price underperformed the index, also benefited the
portfolio.

Stocks in other sectors that contributed to relative results included investment
management firm Legg Mason and French integrated oil company TOTAL*, neither of
which are held in the index.

DETRACTORS FROM PERFORMANCE

Stock selection in the technology and leisure sectors held back relative
performance over the period. In technology, procurement software and consulting
services provider Ariba* (not an index constituent), direct-sale computer vendor
Dell, and security software firm Symantec detracted from relative results. In
leisure, advertising and marketing services conglomerate Interpublic Group* was
among the portfolio's top detractors.

Other individual detractors included home mortgage financier Freddie Mac*,
regional bank North Fork Bancorp*, insurance firm American International Group
(AIG)*, moving and relocation services company SIRVA* (not an index
constituent), and discount retailer Family Dollar Stores*. Avoiding integrated
oil company Chevron for most of the first three quarters of the reporting
period, during which the price of the stock rose, and owning its shares during
the fourth quarter when the stock underperformed the index, negatively affected
relative performance.

* Security was not held in the portfolio at period-end.

INTERNATIONAL GROWTH SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 14.91% while Service Class shares provided a
total return of 14.62%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 13.64% for the series' benchmark,
the MSCI EAFE Growth Index.

CONTRIBUTORS TO PERFORMANCE

Stock selection in the technology, utilities and communications, and energy
sectors contributed to the portfolio's relative performance over the period.
Within the technology sector, strong-performing South Korean microchip and
electronics manufacturer Samsung Electronics was the greatest contributor to
relative results. Performance was also bolstered by our holdings in UK radio
chip designer CSR, which gained substantially over the period.

A combination of security selection and an underweighted position in the
utilities and communication sector boosted relative results. The portfolio
benefited from not holding some of the poor-performers in this sector, including
communications companies France Telecom (France) and Deutsche Telekom (Germany).
In the energy sector, global seamless steel pipe manufacturer Tenaris* and
Canadian oil and gas companies Talisman Energy and EnCana were among the
portfolio's top relative contributors.

Securities in other sectors that aided performance included Indian real estate
finance firm Housing Development Finance, global cement producer Cemex, and
Mexican television broadcaster Grupo Televisa.

During the reporting period, the portfolio's currency exposure was a contributor
to relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

DETRACTORS FROM PERFORMANCE

Security selection in the basic materials, special products and services, and
financial services sectors held back performance relative to the benchmark. In
basic materials, not owning strong-performing index constituent Rio Tinto, a
global mining company, hindered results.

Some special products and services holdings were among the portfolio's top
detractors over the period including Singaporean after-market services provider
Accord Customer Care Solutions*. Additionally, holdings in Japanese technology
investment firm Softbank* had a negative impact on relative results as we
eliminated the stock from the portfolio prior to a significant run-up in share
price.

In the financial services sector, holdings in UK banking firm Royal Bank of
Scotland Group*, and not owing benchmark constituent Mitsubishi UFJ Financial
Group (Japan), hurt performance. Elsewhere, German pay-television operator
Premiere*, UK-based apparel retailer NEXT, and Italian Internet services
provider FastWeb dampened results.

The portfolio's cash position was also a detractor from relative performance.
The portfolio holds cash to buy new holdings and to provide liquidity. In a
period when equity markets rose, as measured by the portfolio's benchmark,
holding cash hurt performance versus the benchmark, which has no cash position.

* Security was not held in the portfolio at period-end.

MASSACHUSETTS INVESTORS GROWTH STOCK SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 4.37%, while Service Class shares provided a
total return of 4.15%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 5.26% for the series' benchmark,
the Russell 1000 Growth Index.

DETRACTORS FROM PERFORMANCE

The technology and industrial goods and services sectors were the largest
detractors from relative performance. In both cases, stock selection was the
main reason.

Several technology holdings hurt relative returns including network security
software company Symantec, which was the greatest individual detractor within
the portfolio. Our holdings in semiconductor giant Intel hampered performance as
we added the stock subsequent to a run-up in share price. Other technology
positions that negatively impacted results included software provider Mercury
Interactive* and computer company Dell.

In industrial goods and services, holdings in manufacturing conglomerate Tyco
International, which is not a benchmark constituent, dampened relative results.
The portfolio's virtual avoidance of benchmark constituent Boeing* also
detracted from performance as we missed out on a significant run-up in that
stock's price.

Stock selection and, to a lesser extent, an overweighted position in the weak-
performing leisure sector hindered performance. No individual stocks within this
sector were among the portfolio's top relative detractors.

Although stock selection in health care significantly aided results for the
period, several individual stocks detracted from performance. Specifically,
underweighted positions in pharmaceutical giant Pfizer* and health insurer
UnitedHealth Group, and our holdings in poor-performing biotech firm ImClone*,
negatively affected results.

During the reporting period, the portfolio's currency exposure was also a
detractor from relative performance. All of MFS' investment decisions are driven
by the fundamentals of each individual opportunity and, as such, it is common
for our portfolios to have different currency exposure than the benchmark.

CONTRIBUTORS TO PERFORMANCE

Security selection in the health care sector was the greatest contributor to
relative performance. Within this sector, biotech firms Amgen and Gilead
Sciences were among the portfolio's top contributing stocks as both
significantly outperformed the benchmark over the period. Other health care
holdings that aided results included generic drug manufacturer Teva
Pharmaceutical Industries and pharmaceutical and diagnostic company Roche
Holding, neither of which are benchmark constituents.

Security selection in the basic materials sector, and a combination of
security selection and an overall underweighted position in the financial
services sector, also helped relative performance. No individual holdings in
either sector were among the portfolio's top contributors.

Several individual technology positions boosted results during the period
including diversified technology company Corning and flash memory storage
products maker SanDisk. Additionally, the portfolio's underweighted position in
poor-performing computer giant International Business Machines (IBM)* benefited
relative returns.

In other sectors, drugstore chain CVS and Latin American wireless communications
company America Movil, which is not a benchmark constituent, contributed to
relative results.

* Security was not held in the portfolio at period-end.

MID CAP VALUE SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 7.63%, while Service Class shares provided a
total return of 7.40%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 12.65% for the series' benchmark,
the Russell Midcap Value Index.

DETRACTORS FROM PERFORMANCE

During the reporting period, weak stock selection in the basic materials sector
hurt relative performance. Within this sector, holdings in newsprint maker
Bowater and paper product manufacturer Smurfit-Stone Container were among the
portfolio's top detractors.

A combination of stock selection and an overweighted position in the lagging
leisure sector held back relative results. Within this sector, holdings in radio
stations operator Radio One* proved disappointing to investment results.

Stock selection in the technology and utilities and communications sectors also
hindered relative performance over the period. In technology, communication
equipment manufacturer Avaya* and electronics manufacturing services company
Solectron* detracted from relative results. In utilities and communications,
leading independent power producer Calpine* (not an index constituent)
negatively impacted relative performance.

Stocks in other sectors that detracted from performance included hospital
operator Tenet Healthcare, investment banking and management firm Friedman,
Billings, Ramsey Group*, and sleep products maker Tempur-Pedic International
(not an index constituent). Not holding independent oil refiner Valero Energy
also dampened results.

CONTRIBUTORS TO PERFORMANCE

The portfolio's overweighted position in the strong-performing energy sector
contributed to relative performance. Several individual stocks within the sector
were among the portfolio's top contributors. These included drilling rig
operator GlobalSantaFe, oil and gas producers Devon Energy and Range Resources*,
and oil field services provider BJ Services, none of which are index
constituents. Additionally, oil and gas exploration company Newfield
Exploration, drilling rig operator Pride International, and energy exploration
company EOG Resources* all benefited the portfolio.

Stocks in other sectors that contributed to relative results included online
brokerage services firm AmeriTrade Holding*, drug maker Endo Pharmaceuticals
Holdings* (not an index constituent), and non-urban hospital operator Community
Health Systems*.

* Security was not held in the portfolio at period-end.

NEW DISCOVERY SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 5.21%, while Service Class shares provided a
total return of 4.96%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 4.15% for the series' benchmark,
the Russell 2000 Growth Index.

CONTRIBUTORS TO PERFORMANCE

Stock selection in the health care sector was the greatest contributor to
relative performance. Within this sector, ventricular assist device maker
Thoratec, medical devices manufacturer FoxHollow Technologies*, and
pharmaceutical firm Adams Respiratory Therapeutics* were among the portfolio's
top contributing stocks as they significantly outperformed the benchmark over
the period. Other strong performers in the health care sector that aided results
included brain monitoring company Aspect Medical Systems, diagnostic instruments
firm Ventana Medical Systems, and medical devices maker Conceptus.

Security selection in the technology sector also helped relative performance.
Holdings in this area included flash memory storage products maker SanDisk,
which is not a benchmark constituent, and multimedia software firm Nuance
Communications.

Although the portfolio benefited from strong stock selection in the industrial
goods and services sector, no individual stocks within this sector were among
the portfolio's top contributors.

Individual stocks in other sectors that contributed to relative results included
discount apparel and variety retailer Citi Trends and interactive entertainment
software company THQ.

DETRACTORS FROM PERFORMANCE

An underweighted position and, to a lesser extent, stock selection in the
strong-performing energy sector hindered relative performance. No individual
holdings in this sector were among the portfolio's top detractors.

The special products and services and the retailing sectors also detracted from
relative performance. In both cases, stock selection held back results. Holdings
in moving and relocation services company SIRVA* and hobby and craft retailer
A.C. Moore Arts & Crafts were significant detractors in these sectors.

Although stock selection in technology aided results for the period, several
individual stocks within this sector detracted from performance. The portfolio's
holdings in procurement software and consulting services provider Ariba*,
integrated circuits maker Silicon Laboratories*, voice network products company
AudioCodes*, which is not a benchmark constituent, and networking semiconductor
firm PMC-Sierra negatively affected results.

Stocks in other sectors that hurt relative results included market research and
opinion polling firm Harris Interactive, frozen dessert maker CoolBrands
International*, which is not a benchmark constituent, and sleep products
manufacturer Tempur-Pedic International*. Not holding strong-performing medical
equipment and supplies firm Intuitive Surgical also dampened relative returns.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

* Security was not held in the portfolio at period-end.

RESEARCH INTERNATIONAL SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 16.56%, while Service Class shares provided a
total return of 16.19%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 14.02% for the series' benchmark,
the MSCI EAFE Index.

CONTRIBUTORS TO PERFORMANCE

Security selection in the energy, financial services, and health care sectors
was the primary contributor to the portfolio's relative performance over the
period. In energy, global seamless steel pipe manufacturer Tenaris*, Russian oil
company LUKOIL, neither of which are benchmark constituents, and Norwegian oil
and gas company Statoil boosted results as the stocks significantly outperformed
the overall benchmark.

Within the financial services sector, several strong-performing stocks that are
not benchmark constituents benefited portfolio performance, including Brazilian
banking firm Unibanco-Uniao de Bancos Brasileiros, and South Korean banking
firms Kookmin Bank and Hana Financial Holdings*. Performance in this sector was
also bolstered by Japanese real estate firm Leopalace21 and Japanese financial
services company ORIX.

Although security selection in the health care sector aided relative results
over the period, no individual stocks within this sector were among the
portfolio's greatest contributors.

Securities in other sectors which aided performance included Korean microchip
and electronics manufacturer Samsung Electronics and Brazilian iron ore miner
Companhia Vale do Rio Doce.

During the reporting period, the portfolio's currency exposure was a contributor
to relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

DETRACTORS FROM PERFORMANCE

Security selection in the special products and services sector held back
performance relative to the benchmark. Within this sector, index constituent
Softbank*, a Japanese technology investment firm, was among the portfolio's
greatest detractors as the stock was sold prior to a strong run-up in share
price.

Stock selection in the retailing and basic materials sectors also hurt benchmark
relative performance. Within retailing, UK-based home improvement store operator
Kingfisher* was among the portfolio's greatest detractors. No individual
holdings within basic materials were among the top detractors for the period.

Several stocks in the utilities and communications sector were a drag on
performance, including telecommunications companies Telefonica (Spain) and
Deutsche Telekom* (Germany), and Italian Internet service provider FastWeb,
which is not a benchmark constituent. Elsewhere, holdings in Japanese electronic
devices manufacturer Seiko Epson*, Japanese video game console maker Nintendo,
UK-based pharmaceutical company GlaxoSmithKline, and UK banking firm Royal Bank
of Scotland Group hurt relative results.

* Security was not held in the portfolio at period-end.

STRATEGIC GROWTH SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 1.40%, while Service Class shares provided a
total return of 1.17%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 5.26% for the series' benchmark,
the Russell 1000 Growth Index.

DETRACTORS FROM PERFORMANCE

Over the period, the energy and leisure sectors were the largest detractors from
relative performance. No individual securities within these sectors were among
the top detractors.

Security selection within the technology sector was another major detractor
during the period. Within technology, holdings in software firm Mercury
Interactive* and computer maker Dell, and underweighting Apple Computer, held
back relative results.

Positions within other sectors that detracted from performance included
underweighting pharmaceutical giant Pfizer* and overweighting industrial goods
and services firm Tyco International*.

CONTRIBUTORS TO PERFORMANCE

Security selection within the health care sector contributed to relative
performance. The portfolio's holdings in biotechnology companies Gilead Sciences
and Amgen, generic drug maker Teva Pharmaceutical and hospital operator HCA Inc*
added to results during the period.

Other stocks that contributed to performance during the year included
diversified technology company Corning, microchip and electronics manufacturer
Samsung Electronics, publishing software firm Adobe Systems, and
telecommunications equipment company QUALCOMM.

* Security was not held in the portfolio at period-end.

STRATEGIC VALUE SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of -0.39%, while Service Class shares provided a
total return of -0.72%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 7.05% for the series' benchmark,
the Russell 1000 Value Index.

DETRACTORS FROM PERFORMANCE

Relative to the portfolio's benchmark, utilities and communications, technology,
and basic materials were the portfolio's largest detracting sectors over the
period. In all three sectors, stock selection held back relative returns. In the
utilities and communications sector, independent power producer Calpine*, which
is not a benchmark constituent, and telecommunications services provider Verizon
were among the portfolio's top detractors for the period.

Stock selection within the technology sector also hurt relative results.
Holdings in network security software company Symantec and global
telecommunications equipment maker Nortel Networks, which is not a constituent
of the benchmark, dampened relative results.

In basic materials, the portfolio's holdings in newsprint maker Bowater and
package manufacturer Owens-Illinois detracted from relative returns as both
stocks underperformed the benchmark.

Stocks in other sectors that hindered investment results included overweighted
positions in poor-performing health services provider Tenet Healthcare,
manufacturing conglomerate Tyco International, which is not a benchmark
constituent, advertising and marketing services company Interpublic Group*, and
media giant Viacom.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

CONTRIBUTORS TO PERFORMANCE

Energy, financial services, and autos and housing were the portfolio's top
contributing sectors over the period. Stock selection in the energy sector
helped boost relative results with strong-performing drilling rig operator
GlobalSantaFe, offshore drilling company Noble Corp, and oil field services
provider BJ Services, none of which are benchmark constituents, among the
portfolio's top contributors. Holdings in oil and gas producer Devon Energy and
oil and gas equipment manufacturer Cooper Cameron also contributed to relative
returns.

In financial services, overweighting PNC Financial Services Group aided relative
performance as the stock outperformed the benchmark over the period.

Although autos and housing was a top-contributing sector, no individual stocks
within the sector were among the portfolio's top contributors.

Stocks in other sectors that aided relative results included overweighted
positions in software developer Compuware, consumer electronics retailer Circuit
City, and cell phone manufacturer Nokia, which is not a benchmark constituent.
The portfolio's avoidance of poor-performing pharmaceutical giant Pfizer also
helped relative results.

* Security was not held in the portfolio at period-end.

TECHNOLOGY SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 6.19%, while Service Class shares provided a
total return of 6.02%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 2.03% for the series' benchmark,
the Goldman Sachs Technology Index.

CONTRIBUTORS TO PERFORMANCE

Security selection within the computer software industry contributed to relative
performance. During the period, the portfolio's holdings in business software
providers MicroStrategy and Opsware, publishing software company Adobe Systems,
and network security firm Blue Coat Systems* added to returns.

A combination of security selection and an underweighting in the electronics
industry boosted relative performance. Holdings in flash memory storage products
company SanDisk, networking chip maker Marvell Technology, and electronics
manufacturer Samsung Electronics were among the portfolio's top contributors. In
the Internet industry, strong-performing Google contributed to relative
performance.

An underweighted position in International Business Machines (IBM)* and holdings
in strong-performing Apple Computer also helped relative results.

DETRACTORS FROM PERFORMANCE

Athough the business services and broadcast and cable television industries held
back relative performance, no individual securities from either industry were
among the portfolio's top detractors for the period.

Within the leisure and toys industry, holdings in video game company Electronic
Arts* hurt performance as the stock underperformed the benchmark over the
period.

Although the computer software industry contributed to relative performance,
several stocks within this group dampened investment results. Holdings in
testing software company Mercury Interactive* and network security software firm
Symantec held back returns. Avoiding strong-performing computer maker
Hewlett-Packard (an index constituent) detracted from relative returns. The
portfolio's exposure to liquid crystal display (LCD) maker LG. Philips LCD also
negatively impacted results.

Elsewhere, holdings in telecommunications equipment company Motorola*,
diversified technology company Corning, e-commerce software vendor Ariba*,
network storage company Network Appliance*, and LCD flat panel display maker AU
Optronics* held back relative returns.

During the reporting period, the portfolio's currency exposure detracted from
relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

* Security was not held in the portfolio at period-end.

VALUE SERIES

SUMMARY OF RESULTS

For the twelve months ended December 31, 2005, Initial Class shares of the
series provided a total return of 6.60%, while Service Class shares provided a
total return of 6.34%. These returns do not reflect any applicable contract or
surrender charges and compare with a return of 7.05% for the series' benchmark,
the Russell 1000 Value Index.

DETRACTORS FROM PERFORMANCE

Security selection and, to a lesser extent, an overweighted position in the
basic materials sector held back relative performance. Within the basic
materials sector, overweighting manufacturing firm PPG Industries and paper and
packaging company International Paper detracted from results as both stocks
lagged the benchmark.

Poor stock selection within the retailing and utilities and communications
sectors also detracted from relative performance. Within these sectors, holdings
in retailer Gap and mobile telecommunications firm Vodafone Group (not index
constituents) dampened investment results.

Elsewhere, within the financial services sector, holdings of mortgage giant
Fannie Mae negatively impacted performance. Underweighting technology firm
Hewlett-Packard* was a drag on results as the stock performed strongly during
the period. Health care company Johnson & Johnson (not an index constituent)
also held back relative returns. Overweighting leisure firm Viacom weighed on
results. Not participating in the substantial run-up in the shares of energy
firms Burlington Resources and Valero Energy was also detrimental to
performance.

During the reporting period, the portfolio's currency exposure was a detractor
from relative performance. All of MFS' investment decisions are driven by the
fundamentals of each individual opportunity and, as such, it is common for our
portfolios to have different currency exposure than the benchmark.

CONTRIBUTORS TO PERFORMANCE

Security selection within the industrial goods and services sector added to
relative performance over the period. Avoiding index constituent General
Electric aided results as the stock lagged the return of the benchmark.

A combination of stock selection and, to a lesser extent, underweighting the
leisure sector boosted relative returns over the period. Although the leisure
sector was a top contributing sector on a relative basis, no individual
securities within the sector were among the top portfolio's contributors.

Security selection drove positive results in the energy sector. Overweighting
energy firms Unocal*, ConocoPhillips, EOG Resources, and Noble Corp (not an
index constituent) benefited the portfolio.

Elsewhere, underweighting weak-performing pharmaceutical giant Pfizer* bolstered
performance. Our holdings in strong-performing investment bank Goldman Sachs and
insurer MetLife were also among the portfolio's top contributors. Finally, in
the transportation sector the portfolio's holdings in Burlington Northern Santa
Fe and our holdings in consumer staples firm Altria Corp positively affected
performance.

NOTES TO PERFORMANCE SUMMARY

Initial Class shares have no sales charge. Service Class shares have no sales
charge and carry a 0.25% annual 12b-1 fee.

Service Class share performance includes the performance of Initial Class
shares for periods prior to the inception of Service Class shares (blended
performance). These blended performance figures have not been adjusted to take
into account differences in the class-specific operating expenses (such as
Rule 12b-1 fees). Because operating expenses of Service Class shares are
generally higher than those of Initial Class shares, the blended Service Class
shares performance shown is higher than it would have been had Service Class
shares been offered for the entire period.

Performance results reflect any applicable expense subsidies and waivers in
effect during the periods shown; without these the results would have been
less favorable. See the prospectus for details. All results are historical and
assume the reinvestment of any dividends and capital gains distributions.

The returns for the series shown do not reflect the deduction of expenses
associated with variable products, such as mortality and expense risk charges,
separate account charges, and sales charges imposed by insurance company
separate accounts. Such expenses would reduce the overall returns shown.

From time to time the series may receive proceeds from litigation settlements,
without which performance would be lower.

KEY RISK CONSIDERATIONS

CAPITAL OPPORTUNITIES SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments.

CORE EQUITY SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments.

INTERNATIONAL GROWTH SERIES

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

MASSACHUSETTS INVESTORS GROWTH STOCK SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Growth stocks may perform differently
from the general stock market and can be more volatile than other types of
stocks.

MID CAP VALUE SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. The securities of medium size
companies may be more volatile than those of larger companies. Value stocks
may perform differently from the general stock market and can continue to be
undervalued for long periods of time and not realize their full value.

NEW DISCOVERY SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. The securities of small size companies
may be more volatile than those of larger companies. Growth stocks may perform
differently from the general stock market and can be more volatile than other
types of stocks.

RESEARCH INTERNATIONAL SERIES

Stock markets are volatile and can decline due to adverse issuer, political.
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Investing in emerging markets can
involve risks in addition to those generally associated with investing in more
developed foreign markets. Changes in currency exchange rates may affect the
portfolio's net asset value, the value of dividends and interest earned, and
gains and losses realized on the sale of securities.

STRATEGIC GROWTH SERIES

Stock markets are volatile and can decline due to adverse issuer, political,
regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Growth stocks may perform differently
from the general stock market and can be more volatile than other types of
stocks.

regulatory or economic conditions. The value of the portfolio's equity
investments will fluctuate in response to many factors including company
specific factors as well as general market conditions. Foreign investments can
be more volatile than U.S. investments. Because the portfolio's investments
are focused in a particular industry or sector, the portfolio's performance
may depend more heavily on the performance of that industry or sector and
therefore may be more volatile than the market as a whole.

risks considerations.

EXPENSE TABLES
SERIES EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD,
JULY 1, 2005 THROUGH DECEMBER 31, 2005

As a shareholder of the series, you incur ongoing costs, including management
fees; distribution (12b-1) fees; and other series expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing
in the series and to compare these costs with the ongoing costs of investing
in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period, July 1, 2005 through December 31,
2005.

ACTUAL EXPENSES
The first line for each share class in the following tables provides
information about actual account values and actual expenses. You may use the
information in this line, together with the amount you invested, to estimate
the expenses that you paid over the period. Simply divide your account value
by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number in the first line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your
account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line for each share class in the following tables provides
information about hypothetical account values and hypothetical expenses based
on the series' actual expense ratio and an assumed rate of return of 5% per
year before expenses, which is not the series' actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the series and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight the
series' ongoing costs only and do not take into account the fees and expenses
imposed under the variable contracts through which your investment in the
series is made. Therefore, the second line for each share class in the tables
is useful in comparing ongoing costs associated with an investment in vehicles
(such as the series) which fund benefits under variable annuity and variable
life insurance contracts and to qualified pension and retirement plans only,
and will not help you determine the relative total costs of investing in the
series through variable annuity and variable life insurance contracts. If the
fees and expenses imposed under the variable contracts were included, your
costs would have been higher.

MFS/SUN LIFE SERIES TRUST

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the series' financial performance for the past 5 years (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.

FINANCIAL HIGHLIGHTS  -- continued

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

(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the
    timing of sales of series shares and the amount of per share realized and unrealized gains and losses at such time.
(d) Per share data are based on average shares outstanding.
(b) The series' net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administra tive proceeding regarding disclosure of brokerage allocation practices in connection with fund 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. 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
    0.13%.
(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
    administra tive proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. The
    non-recurring accrual did not have a material impact on the net asset value per share based on the shares outstanding on

MFS/SUN LIFE SERIES TRUST

NOTES TO FINANCIAL STATEMENTS

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

The series denoted with an asterisk above are included within these financial
statements.

(2) SIGNIFICANT ACCOUNTING POLICIES
General - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Certain
series can invest in foreign securities, including securities of emerging market
issuers. Investments in foreign securities are vulnerable to the effects of
changes in the relative values of the local currency and the U.S. dollar and to
the effects of changes in each country's legal, political, and economic
environment. The markets of emerging markets countries are generally more
volatile than the markets of developed countries with more mature economies. All
of the risks of investing in foreign securities previously described are
heightened when investing in emerging markets countries.

Investment Valuations - Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported by an independent pricing service on the market or exchange on which
they are primarily traded. For securities for which there were no sales during
the day, equity securities are generally valued at the last quoted bid price as
reported by an independent pricing service on the market or exchange on which
they are primarily traded. Debt instruments (other than short-term instruments),
including restricted debt instruments, are generally valued at an evaluated bid
price as reported by an independent pricing service. Values of debt instruments
obtained from pricing services can utilize both dealer- supplied valuations and
electronic data processing techniques which take into account factors such as
institutional-size trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics and other market
data. Short-term instruments with a maturity at issuance of 365 days or less are
generally valued at amortized cost, which approximates market value. Open-end
investment companies are generally valued at their net asset value per share.
Securities and other assets generally valued on the basis of information from an
independent pricing service may also be valued on the basis of information from
brokers and dealers. The values of foreign securities and other assets and
liabilities expressed in foreign currencies are converted to U.S. dollars based
upon exchange rates provided by an independent source. When pricing-service
information or market quotations are not readily available, securities are
priced at fair value as determined under the direction of the Board of Trustees.
For example, in valuing securities that trade principally on foreign markets,
events reasonably determined to be significant (such as certain movements in the
U.S. securities market, or other regional and local developments) may occur
between the time that foreign markets close (where the security is principally
traded) and the series' valuation time that may impact the value of securities
traded in these foreign markets. In these cases, the series may utilize
information from an external vendor or other sources to adjust closing market
prices of foreign equity securities to reflect what it believes to be the fair
value of the securities as of the series' valuation time. Fair valuation of
foreign equity securities may occur frequently based on an assessment that
events which occur on a fairly regular basis (such as U.S. market movements) are
significant.

Repurchase Agreements - Each series may enter into repurchase agreements with
institutions that the series' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. Each series
requires that the securities collateral in a repurchase transaction be
transferred to the custodian in a manner sufficient to enable the series to
obtain those securities in the event of a default under the repurchase
agreement. Each series monitors, on a daily basis, the value of the collateral
to ensure that its value, including accrued interest, is greater than amounts
owed to the series under each such repurchase agreement. Each series, along with
other affiliated entities of Massachusetts Financial Services Company (MFS), may
utilize a joint trading account for the purpose of entering into one or more
repurchase agreements.

Foreign Currency Translation - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of both
realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

Security Loans - State Street Bank and Trust Company ("State Street"), as
lending agent, may loan the securities of each series to certain qualified
institutions (the "Borrowers") approved by the series. The loans are
collateralized at all times by cash and/or U.S. Treasury securities in an amount
at least equal to the market value of the securities loaned. State Street
provides each series with indemnification against Borrower default. Each series
bears the risk of loss with respect to the investment of cash collateral. On
loans collateralized by cash, the cash collateral is invested in a money market
fund or short-term securities. A portion of the income generated upon investment
of the collateral is remitted to the Borrowers, and the remainder is allocated
between the series and the lending agent. On loans collateralized by U.S.
Treasury securities, a fee is received from the Borrower, and is allocated
between the series and the lending agent. The dividend and interest income
earned on the securities loaned is accounted for in the same manner as other
dividend and interest income.

Investment Transactions and Income - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
discount is amortized or accreted for financial statement purposes in accordance
with U.S. generally accepted accounting principles. All discount is accreted for
tax reporting purposes as required by federal income tax regulations. Dividends
received in cash are recorded on the ex-dividend date. Certain dividends from
foreign securities will be recorded as soon as each series is informed of the
dividend if such information is obtained subsequent to the ex-dividend date.
Dividend and interest payments received in additional securities are recorded on
the ex-dividend or ex-interest date in an amount equal to the value of the
security on such date.

Each series may receive proceeds from litigation settlements involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss in
the Statements of Operations, or in unrealized gain/loss if the security is
still held by the series.

Fees Paid Indirectly - Certain series' custody fees are reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
series. During the year ended December 31, 2005, certain series' custodian fees
were reduced under this arrangement as noted below. Certain series have entered
into a commission recapture agreement, under which certain brokers will credit
the series a portion of the commissions generated, to offset certain expenses of
the series. For the year ended December 31, 2005, certain series' custodian
expenses were reduced under this agreement as noted below. These amounts are
shown as a reduction of total expenses on the Statements of Operations.

Tax Matters and Distributions - Each series intends to continue 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 generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share.
Temporary differences which arise from recognizing certain items of income,
expense, gain or loss in different periods for financial statements and tax
purposes will reverse at some time in the future. Distributions in excess of
net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income for financial statement and tax purposes.

Book/tax differences primarily relate to net operating losses, real estate
investment trusts, passive foreign investment companies, wash sale loss
deferrals, and foreign currency transactions.

The tax character of distributions declared to shareholders is as follows:

are declared separately for each class. Differences in per share dividend
rates are generally due to differences in separate class 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
and certain other MFS funds (the funds) for which MFS acts as investment
adviser. Under an administrative services agreement, the funds may partially
reimburse MFS the costs incurred to provide these services, subject to review
and approval by the Board of Trustees. Each fund is allocated a portion of
these administrative costs based on its size and relative average net assets.
The administrative services fee incurred for the year ended December 31, 2005
was equivalent to an annual effective rate of each series' average daily net
assets as follows:

                                                               Percent of

directly to Trustees who are officers of the investment adviser, or to officers

provides for payment of fees by the funds to Tarantino LLC in return for the

(6) LINE OF CREDIT
Each series and other affiliated funds participate in a $1 billion unsecured
line of credit provided by a syndication of banks under a credit agreement.
Borrowings may be made for temporary financing needs. Interest is charged to
each series, based on its borrowings, at a rate equal to the Federal Reserve
funds rate plus 0.35%. In addition, a commitment fee, based on the average
daily, unused portion of the line of credit, is allocated among the
participating funds at the end of each calendar quarter. The commitment fee
allocated to each series for the year ended December 31, 2005 is included in
miscellaneous expense on the Statements of Operations and is as follows for
each series:

                                                         Commitment

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and the Shareholders of MFS/Sun Life Series Trust:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of MFS/Sun Life Series Trust (the "Trust"),
comprising Capital Opportunities Series, Core Equity Series, International
Growth Series, Massachusetts Investors Growth Stock Series, Mid Cap Value
Series, New Discovery Series, Research International Series, Strategic Growth
Series, Strategic Value Series, Technology Series and Value Series as of
December 31, 2005, and the related statements of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Trust
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2005, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial positions of Capital
Opportunities Series, Core Equity Series, International Growth Series,
Massachusetts Investors Growth Stock Series, Mid Cap Value Series, New Discovery
Series, Research International Series, Strategic Growth Series, Strategic Value
Series, Technology Series and Value Series as of December 31, 2005, the results
of their operations for the year then ended, the changes in their net assets for
each of the two years in the period then ended, and their financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America.

BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENTS

The Investment Company Act of 1940 requires that both the full Board of Trustees
and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Trust's investment advisory
agreements with Massachusetts Financial Services Company (MFS) on behalf of the
Series. The Trustees consider matters bearing on the Series and their advisory
arrangements at their meetings throughout the year, including a review of
performance data at each regular meeting. In addition, the independent Trustees
met several times over the course of three months beginning in May and ending in
July 2005 ("contract review meetings") for the specific purpose of considering
whether to approve the continuation of the investment advisory agreements for
the Series. The independent Trustees were assisted in their evaluation of the
investment advisory agreements by independent legal counsel, from whom they
received separate legal advice and with whom they met separately from MFS
management during various contract review meetings. The independent Trustees
were also assisted in this process by the Series' Independent Chief Compliance
Officer, a full-time senior officer appointed by and reporting to the
independent Trustees.

In connection with their deliberations, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light of
the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreements were considered separately for each
Series, although the Trustees also took into account the common interests of all
Series in their review. As described below, the Trustees considered the nature,
quality, and extent of the various investment advisory, administrative, and
shareholder services performed by MFS under the existing investment advisory
agreements and other arrangements with the Trust.

In connection with their contract review meetings, the Trustees received and
relied upon materials which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of each Series for various
time periods ended December 31, 2004, compared to the investment performance of
a group of funds with substantially similar investment classifications/
objectives (the "Lipper performance universe"), as well as the investment
performance of a group of funds identified by objective criteria suggested by
MFS ("peer funds"), (ii) information provided by Lipper Inc. on each Series'
advisory fees and other expenses compared to the advisory fees and other
expenses of comparable funds identified by Lipper (the "Lipper expense group"),
as well as the advisory fees and other expenses of peer funds identified by
objective criteria suggested by MFS, (iii) information provided by MFS on the
advisory fees of comparable portfolios of its other clients, including
institutional separate account and other clients, (iv) information as to
whether, and to what extent applicable, expense waivers, reimbursements or fee
"breakpoints" are observed for a Series, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Series, (vi)
MFS' views regarding the outlook for the mutual fund industry and its strategic
business plans, (vii) descriptions of various functions performed by MFS for the
Trust, such as compliance monitoring and portfolio trading practices, and (viii)
information regarding the overall organization of MFS, including information
about MFS' senior management and other personnel providing investment advisory,
administrative and other services to the Series. The comparative performance,
fee and expense information prepared and provided by Lipper Inc. was not
independently verified, and the independent Trustees did not independently
verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreements was based on comprehensive consideration of all information provided
to the Trustees and not the result of any single factor. Some of the factors
that figured particularly in the Trustees' deliberations are described below for
each Series, while individual Trustees may have given different weight to
various factors and evaluated the information presented as a whole differently
than another Trustee. The Trustees recognized that the fee arrangements for the
Series reflect years of review and discussion between the independent Trustees
and MFS, that certain aspects of such arrangements may receive greater scrutiny
in some years than others, and that the Trustees' conclusions may be based, in
part, on their consideration of these same arrangements during the course of the
year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees compared each
Series' total return investment performance to the performance of peer groups of
funds over various time periods. The Trustees placed particular emphasis on the
total return performance of each Series' Initial Class shares in comparison to
the performance of funds in its Lipper performance universe over the one-,
three- and five-year periods. The Trustees did not rely on performance results
for more recent periods, including those shown elsewhere in this report.

In the course of their deliberations, the Trustees took into account information
provided by MFS during contract review meetings, as well as during investment
review meetings conducted with portfolio management personnel during the course
of the year. For Series whose performance lagged their peer groups, they
discussed MFS' efforts to improve such Series' performance. After reviewing this
information, the Trustees concluded, within the context of their overall
conclusions regarding the investment advisory agreements, that they were
satisfied with MFS' responses and efforts relating to investment performance.

In assessing the reasonableness of each Series' advisory fee, the Trustees
considered, among other information, each Series' advisory fee and the total
expense ratio of the Series' Initial Class shares as a percentage of average net
assets, compared to the advisory fee and total expense ratios of peer groups of
funds based on information provided by Lipper Inc. and MFS. The Trustees also
considered the advisory fees charged by MFS to institutional accounts. In
comparing these fees, the Trustees considered the generally broader scope of
services provided by MFS to the Trust than those provided to institutional
accounts. The Trustees also considered the higher demands placed on MFS'
investment personnel and trading infrastructure as a result of the daily cash
in-flows and out-flows of the Series, and the impact on MFS and related expenses
due to the more extensive regulatory regime to which the Series are subject,
compared to institutional accounts.

The Trustees also considered whether a Series is likely to benefit from any
economies of scale due to future asset growth. In this regard, the Trustees
reviewed the adequacy of breakpoints, and considered if breakpoints should be
implemented for any Series that did not have them.

The Trustees also considered information prepared by MFS relating to its costs
and profits with respect to the Series and other investment companies and
accounts advised by MFS, as well as MFS' methodologies used to determine and
allocate its costs to the Series and other accounts and products for purposes of
estimating profitability.

After reviewing these and other factors described below, the Trustees concluded
that the advisory fees charged to the Series represent reasonable compensation
in light of the nature and quality of the services being provided by MFS.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Series.
The Trustees also considered the financial resources of MFS and its affiliation
with Sun Life Financial Inc. The Trustees further considered any advantages and
possible disadvantages of having an adviser which also serves other investment
companies as well as institutional accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the
Series by MFS and its affiliates under agreements and plans other than the
investment advisory agreements, including the 12b-1 fees the Series pay to MFS
Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges on
the Series' behalf, including securities lending programs, directed expense
payment programs, class action recovery programs, and MFS' interaction with
third-party service providers, principally custodians and sub-custodians. The
Trustees concluded that the various non-advisory services provided by MFS and
its affiliates on behalf of the Series were satisfactory. The Trustees also
considered the benefits to MFS from the use of the Series' portfolio brokerage
commissions to pay for research and other similar services (including MFS'
current policy not to use "soft dollars" generated by Series portfolio
transactions to pay for third-party research), and various other factors.
Additionally, the Trustees considered so-called "fall-out benefits" to MFS such
as reputational value derived from serving as investment manager to the Trust,
and determined that any such benefits derived by MFS were reasonable and fair.

Based on their evaluation of factors that they deemed to be material, including
those factors described above, and the individual Series factors noted below,
the Board of Trustees, including a majority of the independent Trustees,
concluded that the investment advisory agreements should be continued for an
additional one-year period, commencing September 1, 2005.

CAPITAL OPPORTUNITIES SERIES

The Trustees noted the total return performance of the Series' Initial Class
shares was in the 41st percentile relative to the other funds in the Lipper
Classification Index for the one-year period (the 1st percentile being the best
performers and the 100th percentile being the worst performers). The total
return performance of the Series was in the 84th percentile for the three-year
period and the 83rd percentile for the five-year period ended December 31, 2004,
relative to the Lipper performance universe. Based on the nature and quality of
services provided by MFS and the Series' improving performance, the Board of
Trustees concluded that the Series' performance was adequate.

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

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

  * 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, and analysis of
    certain portfolio holdings verses investment styles.


ITEM 4(e)(1):
Set forth below are the policies and procedures established by the Audit
Committee of the Board of Trustees relating to the pre-approval of audit and
non-audit related services: To the extent required by applicable law,
pre-approval by the Audit Committee of the Board is needed for all audit and
permissible non-audit services rendered to the Funds and all permissible
non-audit services rendered to MFS or MFS Related Entities if the services
relate directly to the operations and financial reporting of the Registrant.
Pre-approval is currently on an engagement-by-engagement basis. In the event
pre-approval of such services is necessary between regular meetings of the
Audit Committee and it is not practical to wait to seek pre-approval at the
next regular meeting of the Audit Committee, pre-approval of such services may
be referred to the Chair of the Audit Committee for approval; provided that the
Chair may not pre-approve any individual engagement for such services exceeding
$50,000 or multiple engagements for such services in the aggregate exceeding
$100,000 between such regular meetings of the Audit Committee. Any engagement
pre-approved by the Chair between regular meetings of the Audit Committee shall
be presented for ratification by the entire Audit Committee at its next
regularly scheduled meeting.

ITEM 4(e)(2):
None, or 0%, of the services relating to the Audit-Related Fees, Tax Fees and
All Other Fees paid by the Fund and MFS and MFS Related Entities relating
directly to the operations and financial reporting of the Registrant disclosed
above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C)
of Rule 2-01 of Regulation S-X (which permits audit committee approval after
the start of the engagement with respect to services other than audit, review
or attest services, if certain conditions are satisfied).

ITEM 4(f):  Not applicable.

ITEM 4(h): The Registrant's Audit Committee has considered whether the
provision by a Registrant's independent registered public accounting firm of
non-audit services to MFS and MFS Related Entities that were not pre-approved
by the Committee (because such services were provided prior to the
effectiveness of SEC rules requiring pre-approval or because such services did
not relate directly to the operations and financial reporting of the
Registrant) was compatible with maintaining the independence of the independent
registered public accounting firm as the Registrant's principal auditors.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

Not applicable to the Registrant.

ITEM 6. SCHEDULE OF INVESTMENTS

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

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

Not applicable to the Registrant.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not applicable to the Registrant.

ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT
COMPANY AND AFFILIATED PURCHASERS.

Not applicable to the Registrant.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

There were no material changes to the procedures by which shareholders may send
recommendations to the Board for nominees to the Registrant's Board since the
Registrant last provided disclosure as to such procedures in response to the
requirements of Item 7(d)(2)(ii)(G) of Schedule 14A or this Item.

ITEM 11. CONTROLS AND PROCEDURES.

(a) Based upon their evaluation of the registrant's disclosure controls and
    procedures (as defined in Rule 30a-3(c) under the Investment Company Act of
    1940 (the "Act")) as conducted within 90 days of the filing date of this
    Form N-CSR, the registrant's principal financial officer and principal
    executive officer have concluded that those disclosure controls and
    procedures provide reasonable assurance that the material information
    required to be disclosed by the registrant on this report is recorded,
    processed, summarized and reported within the time periods specified in the
    Securities and Exchange Commission's rules and forms.

(b) There were no changes in the registrant's internal controls over financial
    reporting (as defined in Rule 30a-3(d) under the Act) that occurred during
    the second fiscal quarter covered by the report that have materially
    affected, or are reasonably likely to materially affect, the registrant's
    internal control over financial reporting.

ITEM 12. EXHIBITS.

(a) File the exhibits listed below as part of this Form. Letter or number the
    exhibits in the sequence indicated.

    (1) Any code of ethics, or amendment thereto, that is the subject of the
        disclosure required by Item 2, to the extent that the registrant
        intends to satisfy the Item 2 requirements through filing of an
        exhibit: Code of Ethics attached hereto.

    (2) A separate certification for each principal executive officer and
        principal financial officer of the registrant as required by Rule 30a-2
        under the Act (17 CFR 270.30a-2): Attached hereto.

(b) If the report is filed under Section 13(a) or 15(d) of the Exchange Act,
    provide the certifications required by Rule 30a-2(b) under the Act (17 CFR
    270.30a-2(b)), Rule 13a-14(b) or Rule 15d-14(b) under the Exchange Act (17
    CFR 240.13a-14(b) or 240.15d-14(b)) and Section 1350 of Chapter 63 of Title
    18 of the United States Code (18 U.S.C. 1350) as an exhibit. A
    certification furnished pursuant to this paragraph will not be deemed
    "filed" for the purposes of Section 18 of the Exchange Act (15 U.S.C. 78r),
    or otherwise subject to the liability of that section. Such certification
    will not be deemed to be incorporated by reference into any filing under
    the Securities Act of 1933 or the Exchange Act, except to the extent that
    the registrant specifically incorporates it by reference: Attached hereto.
