Letter from the President

Dear Contract Owners,

I'm sure you've noticed that whenever financial markets suffer a large decline,
as they did this past spring, there's a flurry of information on "how to deal
with market volatility" -- both in the popular press and from those of us in the
investment business. Our own thinking on this is that, first, for long-term
investors volatility is not necessarily something to be feared; occasional
volatility may in fact be healthy for the markets.

Second, our experience has been that when markets begin to fall, it's often too
late to act. The best response may be to do nothing -- if you're properly
prepared with a long-term plan, created with the help of your investment
professional. To help you create or update that plan and take market volatility
in stride, here are some points you may want to consider the next time you talk
with your investment professional.

1. Volatility can be a good thing

We would argue that the markets today are much healthier than they were before
the period of volatility this past spring, in the sense that stock prices have
returned to more reasonable levels and we have a stronger base for future
growth. Perhaps the worst of the market's wrath descended on companies with very
high stock prices, relative to their earnings, or with business concepts that
looked great in the euphoria of a booming market but in the end appeared to have
no fundamental backing. It has always been our view that one of the best
protections against market volatility is to invest in stocks and bonds of
fundamentally good companies selling at reasonable prices. When discussing
potential investments with your investment professional, you may want to ask how
they fared in previous periods of volatility, as well as in the good times.

2. Invest for the long term

You've heard that before, but we think it's still probably the most important
concept in investing. Time is one of an investor's greatest allies. Over nearly
all long-term periods -- 5, 10, 20 years, and more -- stock and bond returns, as
represented by most common indices, have been positive and have considerably
outpaced inflation. Investing is the best way we know of to make your money work
for you while you're doing something else.

Where investors can get into trouble is by confusing investing with trading. In
our view, traders who buy securities with the intention of selling them at a
profit in a matter of hours, days, or weeks are gambling. We believe this seldom
turns out to be a good strategy for increasing your wealth.

3. Invest regularly

Waiting for the "right time" to invest is almost always a poor strategy, because
only in retrospect do we know when that right time really was. Periods of
volatility are probably the worst times to make an investment decision. Faced
with turmoil in the markets, many investors have opted to simply stay on the
sidelines.

On the other hand, we think one of the best techniques for investing is through
automatic monthly or quarterly deductions from a checking or savings account.
This approach has at least three major benefits. First, you can formulate a
long-term plan -- how much to invest, how often, and into which portfolios -- in
a calm, rational manner, working with your investment professional. Second, with
this approach you invest regularly without agonizing over the decision each time
you buy units. And, third, if you invest equal amounts of money at regular
intervals, you'll be taking advantage of a strategy called dollar-cost
averaging: by investing a fixed amount while the unit cost fluctuates, you end
up with an average unit cost to you that is lower than the average unit price
over your investment period.(1) If all this sounds familiar, it's probably
because you're already taking advantage of dollar-cost averaging by investing
regularly for retirement through a 401(k) or similar account at work.

4. Diversify

One of the dangers of not having an investment plan is that you may be tempted
to simply chase performance, by moving money into whatever asset class appears
to be outperforming at the moment -- small, mid, or large cap; growth or value;
United States or international; stocks or bonds. The problem with this approach
is that by the time a particular area is generally recognized as "hot," you may
have already missed some of the best performance.

International investing offers a case in point. In the 1980s, international
investments, as represented by the Morgan Stanley Capital International (MSCI)
Europe, Australia, Far East (EAFE) Index, outperformed U.S. investments, as
represented by the Standard & Poor's 500 Composite Index (S&P 500), in 7 out of
10 years.(2) For the decade, the MSCI EAFE's average annual performance was 23%,
compared to 18% for the S&P 500. Going into the 1990s, then, an investor looking
only at recent performance might have favored international investments over
U.S. investments.

But the 1990s turned out to be virtually a mirror image of the '80s. Domestic
investments outperformed international investments in 7 out of 10 years, with
the S&P 500 returning an average of 18% annually for the decade and the MSCI
EAFE returning a 7% annual average. Looking ahead, however, we are optimistic
about international markets because we feel that many of the same forces that
propelled the current U.S. economic boom -- deregulation, restructuring, and
increased adoption of technology -- have taken root overseas.

The lesson to be learned is that nobody really knows what asset class will be
the next to outperform or how long that performance will be sustained. We would
suggest that one way to potentially profit from swings in the market -- to
potentially be invested in various asset classes before the market shifts in
their favor -- is with a diversified portfolio covering several asset classes.

If you haven't already done so, we encourage you to discuss these thoughts with
your investment professional and factor them into your long-range financial
planning. Hopefully, the next time the markets appear to be going wild, you'll
feel confident enough in your plan to view periods of volatility as a time of
potential opportunity -- or perhaps just a time to sit back and do nothing.

As always, we appreciate your confidence and welcome any questions or comments
you may have.

Respectfully,


/s/ C. James Prieur

Management Review and Outlook

Capital Appreciation Series

For the six months ended June 30, 2000, the series provided a total return of
6.28%, which compares to a 2.98% return for the average large-cap growth
portfolio tracked by Lipper Inc., an independent firm that reports performance.
The series' return also compares to a - 0.42% return over the same period for
the series' benchmark, the Standard & Poor's 500 Composite Index (the S&P 500).
The S&P 500 is a popular, unmanaged index of common stock total return
performance. The series performance includes the reinvestment of any
distributions but does not reflect any applicable contract or surrender charges.

During the period, technology continued to be our main focus. However, we
significantly changed the make-up of our technology investments. We shifted out
of some of the mainframe software companies that had populated the series at the
beginning of 2000, such as BMC Software, Microsoft, and Compuware. We also cut
back or eliminated some of our larger tech positions, including Oracle and Cisco
Systems, because we felt their stock prices had reached or approached full
value. Fortunately, a good deal of this selling, which significantly decreased
our tech exposure, came before the market and the technology sector suffered
from a serious correction in March and April. During the correction, we
increased our positions in fiber-optic equipment firms Nortel Networks and
Corning.

Much of our tech focus has been tied to the development of e-commerce, where a
significant amount of corporate spending is turning. VeriSign, for example, acts
as the custodian for online transactions, taking care of payments and
validations. Nortel Networks and Corning are fiber-optic equipment firms
benefiting from the explosive expansion of web communications, as more fiber
capacity is needed to carry data. We also increased the series' holdings in two
semiconductor manufacturers, Micron Technology and Intel because we anticipate a
fairly significant upturn in personal computer (PC) sales during the second half
of 2000 for two reasons. First, the holiday selling season typically is a good
time of year for PC sales. Second, since we are now well beyond the Year 2000
phenomenon and the computer bug fears it spawned, we think corporate spending on
computers will increase. We also anticipate continued growth in the server
market, an area where Intel, in particular, has made significant inroads. With
these trends in place, demand for all types of semiconductors, high-speed
processors, and memory chips should outpace very tight supply to help these
companies' prospects.

We also found opportunities in the utilities and communications sector. It's
important to point out that our largest investments here were dedicated to
companies involved with cellular communications. This segment performed much
better than the sector as a whole, based on the dynamic growth of wireless voice
and data communications. For example, you can now access the Internet with a
cellular phone. Two of our top holdings in this area were service providers
Sprint PCS and Vodafone AirTouch. We also invested in companies like Metromedia,
which are developing local fiber networks in metropolitan areas.

We also added to our energy weighting, particularly in the oil services segment,
including drillers like Transocean Offshore and Global Marine. In our view,
these companies have hit the sweet spot of their business cycle. With oil prices
up, more oil companies have sought to increase their drilling activity. A
limited supply of drilling rigs means the prices for these companies' services
have been driven higher.

Our financial services holdings were focused on brokerage stocks such as Merrill
Lynch and Morgan Stanley Dean Witter. These companies have done well due to
strong capital markets activity, and should be well positioned if interest rates
start to trend downward. In the retail sector, we have found our best
opportunities in supermarkets and drug stores, including Safeway, Wal-Mart, and
CVS. At the same time, we have been looking to add to our health care
investments in order to take advantage of the steady earnings growth that we
believe pharmaceutical firms offer, and as a way to balance the series' large
tech stake.

All in all, we've tended to concentrate the series more so than in the past. The
market has been very choppy, with some sectors performing very well and others
really struggling. Our research analysts have worked to identify global trends
in industry and business, so that we can try to either capitalize on them or
avoid them.

On the down side, the series' leisure investments lagged somewhat, including its
cable and radio holdings. The feeling in this sector was that -- with the
Olympics and the U.S. presidential election coming up -- conditions for these
companies could not improve over where they are in 2000. Revenue growth for a
lot of these companies hit record levels, and many investors apparently believed
any economic slowdown would spell nothing but bad news. However, we've remained
positive about these companies' long-term prospects. We felt their struggles
were a result of purely emotional market plays, rather than any deterioration in
their fundamentals. We believe, in the long run, that their continued strong
fundamentals will help their stock prices rebound.

Emerging Growth Series

For the six months ended June 30, 2000, the series provided a total return of
-1.66%, which compares to returns over the same period of 3.04% and -0.42%,
respectively, for the series' benchmarks, the Russell 2000 Total Return Index
(the Russell 2000) and the S&P 500. The Russell 2000 is an unmanaged index
comprised of 2,000 of the smallest U.S.-domiciled company common stocks (on the
basis of capitalization) that are traded in the United States on the New York
Stock Exchange, the American Stock Exchange, and NASDAQ. The series performance
includes the reinvestment of any distributions but does not reflect any
applicable contract or surrender charges.

A global correction in the high-growth segments of the market in which we invest
began late in the first quarter of 2000. Fueled by investor concerns over
further Federal Reserve Board (Fed)

2
<PAGE>
Management Review and Outlook -- continued

interest rate increases, this correction in the valuations of technology, media,
telecommunications, and biotechnology stocks continued into the first two months
of the second quarter.

In early June, we began to see some signs that the Fed's six interest rate
increases since last summer may have begun to slow the economy. Some key
economic indicators, including a modest rise in unemployment, a slowing in
housing starts, and lower-than-expected wage gains, gave us hope that there will
be fewer or no increases going forward. We also have seen more attractive
valuations in the high-growth areas of the market, and we believe we may have
seen the lows in the NASDAQ Composite Index (an unmanaged, market-weighted index
of all over-the-counter common stocks traded on the National Association of
Securities Dealers Automated Quotation System) following the correction earlier
this year. While we anticipate further market volatility as investors adjust to
the latest news on the economy and interest rates, we believe we may be entering
a more favorable investment environment.

One of our key strategies during the period was to upgrade the portfolio by
adding to our positions in those companies that we believe will emerge as the
true long-term leaders in their industries, capable of generating the strongest
relative earnings growth. In light of the rising interest rate environment we
had earlier this year, we also reduced our positions in some of our highest
valuation stocks that we felt had limited upside earnings potential, and added
selectively to more defensive names such as generic drug companies and
pharmaceutical companies and food and drug retailers.

We still expect to find our best investment ideas in technology,
telecommunications, and health care. Particularly in an environment where
interest rates stabilize or drop, these high-growth segments of the market could
continue to deliver strong revenue and earnings growth.

We continue to focus on technology as our core sector because we believe tech
companies offer the most attractive growth characteristics that we can identify
across a range of industries. Although we have shifted our tech weightings from
time to time, we are well positioned to take advantage of what we expect to be
much narrower leadership than we've seen in the past. We expect to see certain
core, high-quality tech companies emerge as leaders in their respective markets.

Among our tech holdings were several companies that enable e-commerce, both
business to business and business to consumer. We believe the most successful
will be those with the scale to meet the demands of corporations eagerly buying
the latest business technologies in order to stay competitive. Our tech holdings
include select Internet infrastructure and software companies such as VeriSign,
in addition to semiconductor companies such as Micron Technology and Intel.

With respect to telecommunications, we have reduced our holdings in telecom
service providers because of changes taking place in the industry. Most notably,
the cost of doing business, particularly in terms of licensing and capital
spending, is rising, thus making these companies less profitable in the long
run. Our largest telecom holdings were in telecom equipment companies such as
Nortel Networks, Corning, CIENA, and ADC Telecommunications.

In health care, we have targeted quality names such as the emerging
pharmaceutical company, Sepracor, and companies that make equipment used in
genetics research such as PE Biosystems. Among the thousands of health care
companies available, we're focusing on the biotechnology and emerging
pharmaceutical companies with the best intellectual property and product
pipelines, both of which should help them better meet shareholder expectations.
Finally, we're somewhat cautious on retail because rising interest rates tend to
dampen consumer confidence and slow the pace of consumer spending.

We are in a volatile period where we need to see how much further interest rates
must rise in order to cool off the economy. We remain optimistic on the
long-term outlook for growth stocks, and believe the market leadership will
continue to be in technology, telecommunications, and select parts of health
care. Within these sectors, we are working to build positions in companies that
can become leaders in their industries and deliver growth over long periods of
time, thus creating value for their shareholders.

Global Growth Series

For the six months ended June 30, 2000, the series provided a total return of
-0.78%, which compares to a -1.19% return for the average global portfolio
tracked by Lipper Inc. The series' return also compares to returns over the same
period for the series' benchmarks: -0.42% for the S&P 500; 3.04% for the Russell
2000 Total Return Index; and -2.56% for the Morgan Stanley Capital International
(MSCI) All Country World Index, an unmanaged index of developed-country and
emerging market equities. The series performance includes the reinvestment of
any distributions but does not reflect any applicable contract or surrender
charges.

The strong gains the series enjoyed during the first quarter of 2000 due to its
relatively large stake in the three industry groups that dominated the global
markets, namely technology, telecommunications, and media companies, were
essentially erased during the April and May selloff. Amid concerns about
valuations and interest rates, some of the series' largest technology holdings
experienced choppy performance. The share price of Oracle, which makes the
software that has become the foundation for many Web sites, e-commerce, and
corporate networks, produced a modest gain. Cisco, the leading maker of the
network devices that have become the backbone of the Internet, was essentially
unchanged during the period.

While many of our tech holdings, especially semiconductor manufacturers and
equipment companies, such as Altera, Applied Materials, Micron Technology, and
Analog Devices, performed well during the period, fueled by the growing demand
for all types of chips. Holdings such as Microsoft, BMC Software, and Softbank
were disappointments. The double whammy of lackluster earnings and the Justice
Department's call for a breakup of Microsoft led to a lower share price. BMC
Software also performed poorly after reporting disappointing earnings results.
Finally, the Japanese "incubator" Softbank suffered sizable losses because the
company's stock price buckled when investors grew skittish about the valuations
of dot.com-related stocks. Softbank is known as an incubator because it invests
in or acquires growing Internet companies and then helps nurse them along.

We committed a substantial portion of the series' assets to foreign
telecommunications companies because we believe many of them have transformed
themselves from old-line, slow-growth utilities into fast-growing, dynamic
companies -- through their wireless, Internet service, and data transmission
businesses. A good example is Canadian telecommunications equipment

                                                                               3
<PAGE>
Management Review and Outlook -- continued

company Nortel Networks, which posted strong gains thanks to good growth in its
fiber-optic business. In the Netherlands, KPN benefited from its big push into
wireless communications with the acquisition of a German wireless operator,
which transformed the companies into a pan-European provider in the process.
Most of our emerging-market telecom companies also did well. China Telecom, for
example, rose substantially in response to rapid subscriber growth. Some
Brazilian companies -- particularly Telesp -- were winners as that country's
economy rebounded and investors sought out emerging-market telecom companies
that were cheaper alternatives to developed-market investments.

During the second quarter of 2000, we cut back the series' stake in tech
companies a bit to lock in gains and to search for more attractive values
elsewhere. We redeployed this money into a pretty eclectic group of stocks. We
added U.S. retailers such as grocery store chain Safeway and drug store chain
CVS, both of which enjoyed steady earnings growth. A few Japanese pharmaceutical
companies, such as Chugai Pharmaceutical, also caught our attention because we
felt they were trading at attractive levels compared to their U.S. counterparts.
In general, this strategy aided the series' performance.

In Asia, we increasingly turned our focus toward non-bank financial services
stocks. We believe the economic rebound in many Asian economies and the surge in
equity trading volume have made securities firms particularly attractive. We've
taken a similar approach in the United States, where we believe banks are
beginning to feel the pressure of lower-cost Internet competitors. That helps to
explain why we kept most of our financial services holdings in non-banks such as
Merrill Lynch, whose asset management and capital markets businesses continued
to do well.

Looking forward, we're encouraged by the fact that corporate earnings were quite
strong during the past six months. That said, we wouldn't be surprised if the
U.S. market remained volatile as investors try to decipher potentially
contradictory evidence about the direction of the economy and interest rates.
We're also expecting earnings gains in Europe, where we believe a number of
trends seem to be setting up a favorable backdrop. Corporations just recently
have begun to enjoy the benefits of restructuring and consolidation.
Furthermore, we feel Europe appears to be on the verge of a meaningful and
sustainable rebound. In some ways, the present situation in Europe reminds us of
the situation in the United States in the early 1990s. Back then, we believed
that cost cutting combined with an improving economy helped set the stage for
better earnings growth. We think that a similar set of circumstances could take
hold in Europe and buoy stocks there over the next several years. We're not as
confident about the Japanese economy, which continues to teeter on the verge of
a recession. So we plan to be very selective in Japan by using our MFS Original
Research[RegTM] to seek companies that we feel can grow earnings by
differentiating themselves from their competitors. Recovering emerging market
economies, we believe, may also yield some attractive opportunities. But, as
always, emerging markets carry unique risks, so we're likely to limit our
holdings in them.

We're likely to continue our emphasis on technology, telecommunications, and
media stocks as long as we feel that their fundamental growth rates remain
strong and that demand for the companies' goods and services stays firm. Many
companies in those sectors continue to surprise on the upside by growing at much
faster-than-expected rates. Wireless subscription growth rates across the globe
have accelerated much more quickly than originally forecast, while the growth in
data transmission is expanding far faster and to a much greater magnitude than
originally thought. Admittedly, the high valuations for some of these stocks are
unprecedented. Our approach is to be very selective by choosing companies that
we believe have meaningful franchises and legitimate business models that can be
sustained over the long term.

Managed Sectors Series

For the six months ended June 30, 2000, the series provided a total return of
-7.05%, which compares to returns over the same period of -0.42% and -1.54%,
respectively, for the series' benchmarks, the S&P 500 and the Lipper Capital
Appreciation Portfolio Index (the Lipper Index). The Lipper Index is an
unmanaged, net asset value-weighted measure of the largest qualifying portfolios
with capital appreciation as their investment objective. The series performance
includes the reinvestment of any distributions but does not reflect any
applicable contract or surrender charges.

A global correction in the high-growth segments of the market in which we invest
hampered our short-term performance earlier this year. Fueled by investor
concerns over further Federal Reserve Board (Fed) interest rate increases, the
correction in the valuations of technology, media, telecommunications, and
biotechnology stocks began in the second week of March and continued through the
first two months of the second quarter.

Recently, we have seen some signs that the Fed's six interest rate increases
since last summer may have begun to slow the economy. Some key economic
indicators in early June, including a modest rise in unemployment, a slowing in
housing starts, and lower-than-expected wage gains, gave us hope that there will
be fewer or no increases going forward. We also have seen more attractive
valuations in the high growth areas of the market and we believe we may have
seen the lows in the NASDAQ Composite Index following the correction earlier
this year. While we could certainly see further market volatility as investors
adjust to the latest news on the economy and interest rates, we believe we may
be entering a more favorable investment environment.

During the six-month period, we upgraded the portfolio by adding to our
positions in those companies that we believe will emerge as the true long-term
leaders in their industries, capable of generating the strongest relative
earnings growth. At the same time, in light of the rising interest rate
environment we had earlier this year, we reduced our positions in some of our
highest valuation stocks that we felt had limited upside earnings potential and
added selectively to more defensive holdings such as generic drug and
pharmaceutical companies, as well as food and drug retailers.

Our best investment ideas have continued to be in technology,
telecommunications, and health care. We believe that these high-growth segments
of the market could continue to deliver superior revenue and earnings growth,
particularly in a low or stabilizing interest rate environment.

Technology continues to be our core sector because we believe these companies
offer the most attractive growth characteristics that we can identify across a
range of industries. Although we have shifted our tech weighting from time to
time, we are well positioned to take advantage of what we expect to be much
narrower leadership than we've seen in the past. We think that certain core,
high-quality tech companies will become dominant in their respective markets.
Among them, those leaders first to market with new products and services are the
companies we want to own.

Management Review and Outlook -- continued

Many of our technology holdings are companies that enable e-commerce, both
business to business and business to consumer. We believe the most successful
among them will be the companies with the scale to meet the demands of
corporations eagerly buying the latest business technologies in order to stay
competitive. Our tech holdings also include select Internet infrastructure and
software companies such as VeriSign and Check Point, in addition to
semiconductor companies such as Micron Technology and Intel.

In utilities and communications, we owned a number of emerging telecom service
providers last year. We reduced our holdings this year due to changes taking
place in the industry. Most notably, the cost of doing business, particularly in
terms of licensing and capital spending, is expected to go higher and make these
companies less profitable. Our largest telecom holdings were in telecom
equipment companies such as Nortel Networks, ADC Telecommunications, CIENA, and
Corning.

With respect to health care, we have targeted quality names like the emerging

genetics research, like PE Biosystems. Among the thousands of health care
companies available, we're focusing on the biotechnology and emerging
pharmaceutical companies with the best intellectual property and product
pipelines, both of which should help them better meet shareholder expectations.

Based on the positive outlook for oil and gas prices, we have added to our
holdings in the energy services area. We will, however, watch the supply and
demand of oil, given that the price of this commodity drives the prices of these
energy stocks. Finally, we're somewhat cautious on retail because rising
interest rates tend to dampen consumer confidence and slow the pace of consumer
spending.

We are in a volatile period where we need to see how much further interest rates
must rise in order to cool off the economy. Although we expect to see some
interim volatility, for the long term, we are optimistic on growth stocks,
especially in technology, telecommunications, and health care. Within these
sectors, we are working to build positions in companies that can become leaders
in their industries and deliver growth over long periods of time, thus creating
value for their shareholders.

Massachusetts Investors Trust Series

For the six months ended June 30, 2000, the series provided a total return of
0.72%, which compares to a -1.64% return for the average large-cap value
portfolio tracked by Lipper Inc. The series' return also compares to a -0.42%
return over the same period for the series' benchmark, the S&P 500. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

During a difficult period for stocks, the series managed to outperform the S&P
500 primarily because we kept a close eye on valuations in the portfolio. As a
result, we were underweighted in technology stocks relative to the S&P 500,
which has been a big advantage in this volatile environment. At the same time,
we're not simply value investors; we also try to seek out growth at the right
price. Our broad stock selection expresses this philosophy and proved to be a
significant contributor to performance. Our well-diversified portfolio of
holdings, such as Hartford Financial Services, State Street Corp. Pharmacia,
Pfizer, Safeway, and BP Amoco, are all great examples of stocks that we believe
offer favorable growth opportunities at reasonable valuations and that have
provided strong performance.

Early in the year, we were buying pharmaceutical stocks when most investors
shunned that sector. There were several reasons why we were bullish on these
stocks. First, we believe many of the issues surrounding the industry's decline
in 1999 have subsided, including the threat of onerous government pricing
regulation and Medicare reform. Second, many drug stocks maintained strong
growth rates in 1999 and 2000, but were hurt last year by somewhat exaggerated
concerns about fading product pipelines. Today, we see plenty of new products in
the pipeline, and with quicker FDA approval rates, there is always the
possibility that a new blockbuster drug could be right around the corner.
Finally, health care and pharmaceutical stocks historically have held up well in
a weakening economy. If the Federal Reserve Board's rate hikes succeed in
slowing the economy, we believe traditionally stable, steady growers such as
health care stocks could outperform the overall market.

We think there are a lot of opportunities and the potential for large profits in
the technology sector. Some of the fastest-growing and innovative companies in
the world are the ones that create new technologies. However, we recently
decreased the portfolio's exposure to this sector because we could not ignore
their valuations. If stock prices get too far ahead, which we felt they did in
the first quarter of 2000, the stocks may tread water until the companies'
growth rates can catch up. We think very few industries can grow 30% per year
over the long term, but last year many technology stocks were up well over 100%,
and we felt that was just too far too fast. However, while the portfolio has
remained underweighted in tech versus the S&P 500, it was still the largest
sector weighting in the portfolio because we continued to see great
opportunities for long-term growth.

While the holdings and sector weightings of the portfolio will constantly shift
depending on where we find opportunities, we think it's important to emphasize
that our overall strategy remains the same. We continue to try to balance the
portfolio by taking advantage of what we think are the best growth and value
stocks to own at the right time. When growth stocks are in favor, our goal is to
keep pace with the market, and in a value environment, our goal is to
outperform.

Despite the recent selloff, some investors feel the market is still expensive.
From our standpoint, however, no matter what direction the market is headed, it
usually provides opportunities for investors who do their homework. While there
are pockets of the market that still appear pricey, we see strong potential for
the market to head higher given what we view as an environment of healthy
economic growth, reasonable interest rates, and a favorable outlook for
corporate earnings growth. We also have found that it's very difficult to
predict what the market will do in the short term. As a result, we continue to
focus on finding companies that we believe offer the best fundamental business
prospects and the potential for superior long-term performance.

Research Series

For the six months ended June 30, 2000, the series provided a total return of
6.57%, which compares to a -0.42% return for its benchmark, the S&P 500. The
series performance includes the reinvestment of any distributions but does not
reflect any applicable contract or surrender charges.

As we've seen during the past six months, investment trends and styles go in and
out of favor with investors. Consequently, we don't spend too much time trying
to determine when value or growth, small-cap or large-cap stocks will move in
and out of the spotlight. Instead, we focus on finding dominant business

                                                                               5

Management Review and Outlook -- continued

franchises with outstanding managements driving accelerating earnings growth.
It's a bottom-up approach that's based on intensive hands-on research and the
best ideas of our analysts. This approach has led us to some very rewarding
growth opportunities, and the series has held on to its favorable returns during
the six-month period despite the weakness we've seen in the market.

Beyond performance, however, we believe there are other factors that distinguish
this portfolio from its competitors. First and foremost, we believe the depth
and the talent of our equity analysts are big advantages. We have more than 35
equity research analysts at MFS, all contributing their best ideas to the
portfolio. As a result, there is a great deal of information sharing, starting
with our in-depth balance sheet and earnings analysis. At the same time, we all
spend a great deal of time on the road meeting with company managements, as well
as with employees, competitors, and suppliers. We also have a lot of flexibility
with the portfolio. We can look at any market capitalization, location, or
industry. Overall, we lean toward the more dynamic areas of the economy by
focusing on companies that we believe are at the forefront of innovation and are
benefiting from their competitive advantages.

We're finding opportunities in a wide range of areas, but some industries that
have recently performed well for the portfolio are energy, insurance, and
pharmaceuticals. In the energy sector, exploration and production companies,
such as Global Marine and Transocean, have rallied significantly due to the
rebound in oil and natural gas prices. Higher prices have spurred demand for
drilling services, thus resulting in strong revenue and earnings growth at many
energy services companies. Despite a fairly long stretch of weak performance
from insurance stocks, such as Hartford Financial, we held on to these companies
because we believed in their long-term prospects and the possibility of
consolidation in the industry. Recently, we've seen an increase in merger and
acquisition activity in this group that has boosted the performance of these
holdings. In the first quarter of 2000, we took advantage of weakness in
pharmaceutical stocks to increase our holdings in what we believe are top-notch
companies with strong track records, such as Pfizer, Pharmacia, American Home
Products, and Bristol-Myers Squibb. Some of these stocks have come back strongly
in the second quarter, and we believe they still offer attractive growth
prospects.

We've also increased the portfolio's exposure to wireless communications stocks
because we see tremendous growth opportunities for these companies. A few years
ago, roughly 3% of worldwide communications were handled over wireless networks.
Now we have found that percentage has grown to double digits, and we believe
similar growth lies ahead. We expect revenue growth for many wireless companies
to rise 25% to 50% per year, and international revenues could be even higher.
Given our outlook for dramatic growth in this industry, we like the risk/reward
profile of these stocks.

Despite what we think may be a somewhat less robust environment for consumer
spending, we also like companies such as CVS and Safeway because they're
noncyclical. People have to buy prescriptions, household products, and
groceries, regardless of the economic environment. We also happen to think these
are two of the best-run companies in their respective industries. Additionally,
we've increased our positions in Intel and EMC Corp. because we see demand for
their products and services accelerating, their fundamental business prospects
are strong, and we ultimately believe they can maintain their leadership
positions in their respective markets.

Total Return Series

For the six months ended June 30, 2000, the series provided a total return of
2.83%, which compares to a return of 1.34% for the average balanced portfolio
tracked by Lipper Inc. The series' return also compares to a 4.18% return over
the same period for the series' benchmark, the Lehman Brothers Government/
Corporate Bond Index (the Lehman Index), an unmanaged, market-value-weighted
index of all debt obligations of the U.S. Treasury and U.S. government agencies
(excluding mortgage-backed securities) and investment-grade U.S. corporate debt.
The series performance includes the reinvestment of any distributions but does
not reflect any applicable contract or surrender charges.

In our opinion, what makes this portfolio different from other balanced
portfolios is the fact that we remain committed to our disciplined approach to
asset allocation -- unlike managers of many balanced portfolios who often take
on additional risks by increasing their exposure to aggressive growth stocks. We
maintain a roughly 60% equity and 40% fixed-income and cash investment mix
because we believe this is what investors expect from a balanced portfolio. We
believe this strategy provides the right balance of growth and income potential.

Due to a steady rise in interest rates during the past year, it has been a
difficult environment for bonds. However, the portfolio's bond holdings posted
positive returns during the past six months and generally added stability to the
portfolio in a period marked by highly volatile equity markets. At the same
time, our equity stake was bolstered by our focus on value stocks, and strong
security selection in energy and insurance stocks that contributed positively to
the portfolio's total return.

Among energy stocks, oil services as well as exploration and production
companies provided an impressive boost to performance. These stocks -- typically
very sensitive to oil and natural gas price changes -- benefited immensely from
rising prices. We've anticipated this favorable business environment for some
time now and it has worked very well in recent months. In the insurance sector,
a few of the portfolio's holdings produced strong performance. The Dutch
financial services company ING Groep agreed to buy ReliaStar Financial Corp.,
which caused our position in ReliaStar to nearly double. This news sparked a
rally in the insurance industry, as investors began to recognize the strong
fundamental business outlooks and the potential for further consolidation among
insurance companies.

We also took advantage of some weakness in pharmaceutical stock prices in the
early part of the year to increase our positions in high-quality companies with
strong long-term track records. Stocks such as Pharmacia and Abbott
Laboratories, came back strong in the second quarter, and we think they still
offer attractive growth opportunities at compelling valuations.

While value stocks have rallied recently, it's difficult to predict whether this
trend will continue. But our feeling is that there is still plenty of upside for
more reasonably priced stocks with good fundamental growth prospects, especially
if interest rates and the economic backdrop remain uncertain. We think more
defensive stocks in noncyclical sectors of the economy, such as consumer
nondurables and health care stocks, have the potential to outperform aggressive
growth stocks in this environment.

Management Review and Outlook -- continued

As corporate bonds and mortgage-backed securities recovered in the first quarter
of 2000, we decided to secure some profits and decrease our positions in these
sectors. At the same time, we shifted some assets into U.S. Treasuries as the
outlook for government securities appeared to brighten. We felt this strategy
worked well, especially following the government's announced plans to buy back
nearly $30 billion of longer-maturity Treasuries during the year. (Principal
value and interest on Treasury securities are guaranteed by the U.S. government
if held to maturity.) With corporate bonds, we also found ourselves in the right
areas of the market. Our positioning in various telecommunications and media
issues proved particularly beneficial.

Looking forward, while certain pockets of the market remain overvalued in our
view, we are still finding some quality companies at what we think are
attractive prices. In addition, we feel there is potential for strong corporate
earnings across a wide range of industries. However, we intend to proceed with
some caution given the Federal Reserve Board's determination to slow down the
economy. In light of the current economic uncertainty, the market is beginning
to behave as we would expect -- defensive, value-oriented stocks have been
rebounding, while growth stocks have suffered. Whether this current trend will
persist is difficult to determine. As a result, we believe it makes sense for
investors to maintain a well-diversified portfolio.

Utilities Series

For the six months ended June 30, 2000, the series provided a total return of
3.97%, which compares to a 1.60% return during this period for the average
utility portfolio tracked by Lipper Inc. The series' return also compares to a
15.33% return over the same period for the series' benchmark, the Standard &
Poor's Utility Index (the Utility Index), an unmanaged, market-
capitalization-weighted, total return index of all utility stocks in the S&P
500. The series performance includes the reinvestment of any distributions but
does not reflect any applicable contract or surrender charges.

The market has been extremely volatile over the past six months. In the first
quarter of 2000, stocks continued their incredible run, with the biggest gains
coming from technology and other high-growth sectors. But almost as soon as the
new year started, investors grew unsettled. We felt that part of the problem was
renewed concerns about rising interest rates. Also, technology stocks had
reached such high levels that we believe many investors were getting nervous
that they wouldn't be able to meet their earnings forecasts. Finally, in April
and May, growth stock prices declined.

However, utility stocks moved in the opposite direction of the market leaders.
During the first quarter of this year, utility stocks did poorly because their
earnings looked weak compared to the strength in high-growth tech names. But as
the market grew increasingly bumpy, utilities started looking more attractive.
Toward the end of the period, investors were moving into electric utility stocks
for defensive reasons, and their stock prices moved up nicely.

Our strategy is always to own the names we have confidence in -- usually
companies with good earnings growth prospects whose stock prices look
reasonable. A few years ago when we had the meltdown in Asian financial markets,
investors flew into electrics, again for defensive reasons. But they flew out
just as quickly. That was a good lesson. Sure, it would have been nice to have a
higher stake in these utilities when they started moving up. But we just don't
have a lot of confidence right now that the management teams at many of these
companies have the experience to run their businesses effectively in a
deregulated environment. We focused exclusively on companies like Pinnacle West
Capital that we think do seem to have the right skills. This is an Arizona-based
company focused on its nonregulated generation business that's not only well
managed but is operating in a territory with strong growth potential. We believe
that combination may give the company double-digit earnings growth down the
road.

AES and Calpine, two independent power producers, posted exceptionally strong
gains. AES has more of an international focus, whereas Calpine has most of its
power plants here in the United States. But the story is much the same. Both are
capitalizing on two trends in generation -- privatization and deregulation. To
be successful, we believe these companies have to run their plants efficiently
and understand the markets in which they operate.

Natural gas stocks also have been been strong performers and, fortunately, a
sizable focus for the series. We had built our stake in this area for a couple
of reasons. First, we recognized the overall strength in natural gas demand. Our
research shows that today only about 15% of existing electricity generation is
natural gas based, but 95% of the new plants being built are natural gas ones.
We believe the underlying demand for natural gas is going to go up. Second, many
of the natural gas pipeline companies trade in natural gas and electricity.
Basically, we feel they try to take advantage of price volatility by buying
excess capacity at low prices and then reselling it at higher prices to
companies that are running short. Finally, many natural gas pipeline companies,
including Dynegy and El Paso, have been getting into the deregulated power
generation business. We think they have the necessary risk management tools from
their trading experience, as well as an understanding of power generation, to be
very successful.

Williams, another natural gas pipeline stock and one of our largest investments,
was flat for the period. It spun off 15% of its telecommunications subsidiary
about a year ago. Unfortunately, the parent company's stock has moved more in
line with communications stocks than with energy stocks, and telecommunications
has done really badly this spring. The wireless companies and the new
competitive local exchange carriers got killed during the downturn of growth
investing. The story isn't much better with the service providers -- stocks such
as GTE and SBC Communications sunk as investors worried about whether they could
keep up in the rapidly changing telecommunications market. We held on because we
believe these companies will prove they can compete.

Consolidation also has helped the portfolio. We owned El Paso and Coastal,
energy-related companies that announced a merger in February. Both stocks took
pretty hard hits over concerns that the deal just didn't make sense. We knew the
companies well and thought the merger was a good move, especially given the fact
that the combined entity would create the biggest natural gas pipeline company
in the United States. We used the downturn as an opportunity to add to our
position and have since seen both stocks rebound nicely. We also benefited from
selling our stake in Mannesmann, a German wireless and wireline company,
following its announced buyout by Vodafone AirTouch, a British-based mobile
telecommunications provider.

                                                                               7
<PAGE>
Management Review and Outlook -- continued

As long as the stock market remains volatile, we think utility stocks may
provide a safer haven for investors and, therefore, we believe they should do
well. We feel that natural gas stocks seem to have the strongest prospects and
electrics the weakest. But it is important to remember that since we buy
individual stocks, not whole sectors, that's largely irrelevant to our
investment strategy. We'll remain focused on utility companies that we believe
can sustain or improve earnings growth.

MFS/Sun Life Series Trust
Notes to Financial Statements (Unaudited)

(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,
Emerging Growth Series*, Emerging Markets Series, Equity Income Series, Global
Asset Allocation Series, Global Government Series, Global Growth Series*, Global
Total Return Series, Government Securities Series, High Yield Series,
International Growth Series, International Growth and Income Series, Managed
Sectors Series*, Massachusetts Investors Growth Stock Series, Massachusetts
Investors Trust Series*, Money Market Series, New Discovery Series, Research
Series*, Research Growth and Income Series, Research International Series,
Strategic Growth Series, Strategic Income Series, Technology Series, Total
Return Series*, Utilities Series*, and Zero Coupon Series, 2000 Portfolio. All
of these series are diversified except for the Global Asset Allocation Series,
Global Government Series, Global Growth Series, Global Total Return Series, High
Yield Series, Managed Sectors Series, Strategic Income Series, and Utilities
Series, which are non-diversified as that term is defined in the Investment
Company Act of 1940, as amended. 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 generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The series
can invest in foreign securities. Investments in foreign securities are
vulnerable to the effects of changes in the relative values of the local
currency and the U.S. dollar and to the effects of changes in each country's
legal, political, and economic environment.

Investment Valuations -- Equity securities listed on securities exchanges or
reported through the NASDAQ system are reported at market value using last sale
prices. Unlisted equity securities or listed equity securities for which last
sale prices are not available are reported at market value using last quoted bid
prices. Debt securities (other than short-term obligations which mature in 60
days or less), including listed issues and forward contracts, are valued on the
basis of valuations furnished by dealers or by a pricing service with
consideration to factors such as institutional-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics, and other market data, without exclusive reliance upon exchange
or over-the-counter prices. Short-term obligations, which mature in 60 days or
less, are valued at amortized cost, which approximates market value. Non-U.S.
dollar denominated short-term obligations are valued at amortized cost as
calculated in the foreign currency and translated into U.S. dollars at the
closing daily exchange rate. Securities for which there are no such quotations
or valuations are valued in good faith, at fair value, by the Trustees.

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

Security Loans -- State Street Bank and Trust Company ("State Street") and Chase
Manhattan Bank ("Chase"), as lending agents, may loan the securities of each
series, with the exception of the Capital Appreciation Series and Managed
Sectors Series, to certain qualified institutions (the "Borrowers") approved by
each series. The loans are collateralized at all times by cash and/or U.S.
Treasury securities in an amount at least equal to the market value of the
securities loaned. State Street and Chase provide the series with
indemnification against Borrower default. The series bears the risk of loss with
respect to the investment of cash collateral.

Cash collateral is invested in short-term securities. A portion of the income
generated upon investment of the collateral is remitted to the Borrowers, and
the remainder is allocated between the series and the lending agents. On loans
collateralized by U.S. Treasury securities, a fee is received from the Borrower,
and is allocated between the series and the lending agents. Income from
securities lending is included in interest income on the Statements of
Operations. The dividend and interest income earned on the securities loaned is
accounted for in the same manner as other dividend and interest income.

At June 30, 2000, the value of securities loaned and the collateral on these
loans were as follows:

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

Investment Transactions and Income -- Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All discount
is accreted for financial statement and tax reporting purposes as required by
federal income tax regulations. Dividends received in cash are recorded on the
ex-dividend date. Dividend and interest payments received in additional
securities are recorded on the ex-dividend or ex-interest date in an amount
equal to the value of the security on such date.

Fees Paid Indirectly -- Each series' custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
series. During the period, each series' custodian fees were reduced under this
arrangement as noted below. Each series has entered into a directed brokerage
agreement, under which the broker will credit the series a portion of the
commissions generated, to offset certain expenses of the series. During the
period, the series' custodian fees were reduced under this agreement as noted
below. These amounts are shown as a reduction of expenses on the Statements of
Operations.

Tax Matters and Distributions -- Each series' policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its net taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

Distributions to shareholders are recorded on the ex-dividend date. The series
distinguishes between distributions on a tax basis and a financial reporting
basis and only distributions in excess of tax basis earnings and profits are
reported in the financial statements as distributions from paid-in capital.
Differences in the recognition or classification of income between the financial
statements and tax earnings and profits that result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or net realized gains.

(7) Restricted Securities

Each series of the trust is restricted from investing more than a certain amount
in securities which are subject to legal or contractual restrictions on resale.
Such restrictions range from 0% to 15% of the series' net assets. At June 30,

securities issued under Rule 144A, constituting 0.03% of net assets which may
not be publicly sold without registration under the Securities Act of 1933. Each
series does not have the right to demand that such securities be registered. The
value of these securities is determined by valuations furnished by dealers or by
a pricing service, or if not available, in good faith, at fair value, by the
Trustees.
