LETTER FROM THE CHAIRMAN

DEAR CONTRACT OWNERS,

It has been almost two years since financial turmoil began to rock markets in
Asia, Russia, and Latin America. Even developed markets such as Europe and the
United States were not immune. In the U.S. equity market, for example, investors
focused on a narrow group of 50 of the largest-company growth stocks because
they seemed to offer less volatility in uncertain times. Fixed-income investors
also became more concerned about risk, moving money into U.S. Treasury
securities and out of corporate and municipal bonds and mortgage-backed
securities.

The narrowness of the market was just one of three broad issues that dominated
the U.S. equity market until recently. The other two were a slowdown in
corporate earnings growth and high valuations, with stocks of many companies
selling at extremely high prices relative to their earnings.

Although these have been challenging issues, we now see signs that we feel
demonstrate each one is changing for the better. Today, we believe the markets
are presenting more opportunities for investors to diversify, for our portfolio
managers to find good values, and for us to show the benefits of staying with
our long-term objectives and strategies. Investors seem to be regaining
confidence in a wider range of companies. Stocks of some small and mid-sized
companies, as well as some large industrial companies, have begun to perform
better in the past few months than they had for the previous year or so. These
companies appear to have benefited from early signs of stability in emerging
markets and a continuation of economic growth in the United States.

U.S. companies also have produced better earnings. Corporate earnings were, on
average, relatively flat in 1998. However, we expect earnings to grow 12% to 14%
this year because more companies have benefited from the strong economy and from
aggressive consolidation and cost-cutting measures they have taken over the past
several years.

Based on their earnings projections, our analysts estimate that the U.S. stock
market is still about 30% overvalued. While there has been some shift to a wider
group of stocks, many investors are still focusing on the large-company stocks.
As a result, most of the overvaluation is in the 50 largest stocks in the
Standard & Poor's 500 Composite Index (the S&P 500), a popular, unmanaged index
of common stock total return performance. That means about 450 stocks are
selling at more attractive prices, particularly given what we see as the
improved earnings outlooks for these and many small and mid-sized companies not
in the S&P 500. These companies also benefit from consolidation, cost cutting,
and global growth. Because they are smaller, they may be able to respond to
these changes more quickly, and thus they have the potential to grow faster than
the big companies.

The fixed-income markets, meanwhile, seem to be approaching the level of
relative stability they enjoyed before the Asian turmoil. Some credit for this
stability
goes to the Federal Reserve Board (the Fed), which has reassured investors that
it will act to prevent rapid economic growth from causing higher inflation and
reduced purchasing power. Also, once investors saw that the overseas turmoil had
little, if any, effect on the financial strength of most domestic bond issuers,
the major non-Treasury markets -- corporate, municipal, and mortgage -- began to
rebound. Our portfolio managers are now finding more opportunities to buy bonds
with relatively stable prices and attractive yields.

The past two years have challenged investors. However, we believe we are well
positioned for the current environment because our analysts and portfolio
managers continue to rely on MFS-Registered Trademark- Original Research-SM- to
help evaluate the long-term investment potential of each holding being
considered for our portfolios. Also, we believe our discipline of staying with
our clearly defined investment strategies can help us offer investment products
with the potential to sustain returns over a variety of market cycles.

We appreciate your confidence and welcome any questions or comments you may
have.

Respectfully,

/s/ JOHN D. MCNEIL

MANAGEMENT REVIEW AND OUTLOOK

CAPITAL APPRECIATION SERIES
For the six months ended June 30, 1999, the Series provided a total return of
8.30%, which compares to a 12.23% return for the Standard & Poor's 500 Composite
Index (the S&P 500) for the same period. The S&P 500 is a popular, unmanaged
index of common stock total return performance.

We benefited from Microsoft, which held on to its position as the top holding in
the portfolio for the first half of the year. After suffering through declining
stock prices in the winter, the prices of BMC Software, a computer software
company, and Oracle, a database software developer and manufacturer, went up in
the second quarter and the portfolio benefited. Tyco International, an
industrial conglomerate and our second largest holding, continued to perform
well, given its strong earnings growth. MCI WorldCom, a data and
telecommunications company, and Cisco Systems, a computer network developer,
were consistently strong performers. MediaOne, a cable

                                                                               1
<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued
broadcasting company that made a valuable contribution to the portfolio, was
trimmed after the announcement of an AT&T acquisition offer. We added Comcast,
another cable broadcaster, to our holdings because of what we believe to be
strong fundamentals for the company. Because it seemed overvalued, we reduced
our holdings in the drug company Pfizer. We bought American Home Products, which
develops and sells a wide range of drugs and agricultural products and had good
earnings growth and a reasonable price/earnings multiple.

The portfolio underperformed during the first half of the period and
outperformed during the second half. During the first three months, more
cyclically oriented stocks -- energy and specialty retailing, for example --
performed well, and we had relatively few such holdings. Our technology focus
was correct, but we were more concentrated in software stocks at a time when
semiconductor stocks performed strongly. But during the second half of the
period, software stock performance improved significantly.

Some holdings hurt performance during the period. Cadence Design Systems, a
developer of design software and software services, had disappointing earnings.
Compuware, a software products and professional services company, underperformed
due to concerns about a potential slowdown in sales. Rite Aid, the drug store
chain, experienced management and financing problems.

We have significant holdings in the leisure sector, which is focused on two
primary areas: cable operating companies and radio companies. The cable industry
is benefiting from the introduction of digital services, which expands the
breadth of its products offered through cable television. The industry gets an
added boost as a superior connection for Internet-related services. Our primary
cable holdings are Time Warner and Comcast. Radio stocks continued to have a
strong position in the portfolio because the industry benefited from
consolidation and a strong economy. Consolidation has allowed such companies as
Clear Channel Communications to offer more comprehensive advertising packages
that better cover local markets with a larger number of stations and more
professional programming. This has led to stronger demand for advertising time.

We continue to rely on our bottom-up MFS-Registered Trademark- Original
Research-SM- process. Our team of analysts and portfolio managers visits and
calls companies to identify which have the best growth prospects at today's
valuation levels. It does become more difficult to identify new ideas in today's
highly valued market. However, patience and continued hard work will enable us
to add new companies. During the period, we added to our positions in Wendy's
International and McDonald's Corp. as portfolio fundamentals began to improve
for the restaurant industry.

Looking ahead, the Federal Reserve Board's small interest rate increase would
indicate that it is satisfied with the current level of growth in the economy.
Inflation remains under good control, given recent government information about
inflation indices for consumer and wholesale prices. This paints a good overall
backdrop for the stock market, which is recognized by the current valuation
levels. In general, we think that more moderate upside movement should be
expected from the market than we have seen in the past few years of very strong
performance. We will strive to continue to add those companies that best meet
our objective of capital growth of the portfolio.

EMERGING GROWTH SERIES
For the six months ended June 30, 1999, the Series provided a total return of
12.00%, which compares to a 12.13% return for the average mid cap growth fund
tracked by Lipper Analytical Services, Inc. The Series' return also compares to
a 9.28% return for the Russell 2000 Total Return Index (the Russell 2000) and to
a 12.23% return for 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 was impacted by three important factors. First, the
Series has holdings in small, mid-sized, and large companies. Until early April,
when the market began to broaden, its best-performing segment was made up of a
narrow group of about 50 of the largest-company growth stocks in the S&P 500, as
well as some Internet stocks. Prices of the large-company stocks, relative to
their earnings, reached excessive levels. Now, investors have moved into a
broader range of stocks that are selling at cheaper prices relative to their
earnings. We think the broadening of the market will continue, and that should
be a positive for the Series because it invests in companies of all market
capitalizations.

Second, the Series was affected by the fact that we have not invested in many of
the Internet stocks. While we have been generally reluctant to own Internet
companies that have unproven business models, we do own established companies
such as Cisco Systems, which provides systems to support Internet traffic, and
Oracle, which provides one of the leading enabling technologies for
e-commerce. Many of the Internet stocks, including new companies that have shown
no profit, performed very well in the early part of the year. However, when
investors became nervous over their valuations, they rushed out of them. Our
investments in stocks with proven business models helped to protect the
portfolio from a decline in Internet stock speculation.

The third factor has been our exposure to computer software companies. Many
software companies have faced uncertainty over the Year 2000 (Y2K) computer
issue. Earlier this year, it looked like many businesses

2
<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued
would reduce their spending on computer software and systems to give themselves
time to ensure their existing systems were Y2K ready. Although it now looks like
spending won't be cut as much as people feared, the stocks have already been
impacted. We think the Y2K issue will be behind us by next spring. At that time,
we think companies such as BMC Software and Computer Associates, which are
dominant in their markets, should be among the best positioned in what we expect
to be a very rapidly growing industry.

Technology continues to be the Series' largest sector. Companies are still
increasing earnings growth by aggressively downsizing, restructuring, and
outsourcing many business functions. Technology allows these companies to be
more productive without necessarily hiring more people. We believe these trends
will continue both domestically and internationally, and they should continue to
benefit such holdings as Microsoft.

Several of the Series' telecommunications and media holdings also have performed
well. MCI WorldCom is a dominant player in telecommunications and the backbone
of worldwide cellular traffic. MediaOne, which is being acquired by AT&T, has
been a big beneficiary of the growth of cable, both for entertainment and for
Internet access. Also, after several years of not being able to increase prices,
health maintenance organizations such as United HealthCare have been raising
their rates, which we feel should make them more profitable.

GLOBAL GROWTH SERIES
For the six months ended June 30, 1999, the Series provided a total return of
13.27%, which compares to a 6.23% return for the average global flexible fund
tracked by Lipper Analytical Services, Inc. The Series' return also compares to
returns of 12.23% for the S&P 500, 9.28% for the Russell 2000 Total Return
Index, and 10.21% for the Morgan Stanley Capital International (MSCI) All
Country Index, an unmanaged index of developed-country and emerging market
equities.

Investments in emerging markets have helped performance recently. Our emerging
market holdings previously had been hurt by the downturn in that market, which
began in 1997. However, since late 1998, stock prices in emerging markets have
rebounded strongly because investors have become more confident that political
and economic reforms in these countries eventually may result in strong economic
growth.

Several of the Series' U.S. technology and telecommunications holdings,
including Cisco Systems, Microsoft, and Oracle, have also helped performance.
Technology companies, particularly U.S. software companies, continue to help
corporations around the world become more productive. In general, these firms
have been insulated from a slowdown in the economy and continue to generate very
strong earnings growth. Similarly, the explosion in wireless communications and
data transmission has boosted revenues and earnings for telecommunications
companies around the world.

We also like European consumer staples and financial services companies. Stocks
of several consumer staples companies were hurt last year by their exposure to
emerging markets. However, we believe the recent economic improvement in Asia
and Latin America should enable these companies to rebound. Holdings in this
sector include Benckiser, a Dutch company that makes dishwasher detergent and
other household products, and Nestle, a Swiss food company. We also think stock
prices of European financial services companies are attractive in relation to
our earnings and growth outlooks for them. We continue to see opportunities for
consolidation in this sector, which we believe should drive costs down and
result in positive earnings for several years. One of our larger European
holdings in this sector is UBS, a Swiss bank whose stock has risen following its
merger last year with Swiss Bank Corp. The rapid growth of the European media
and communications industry also has helped such broadcast holdings as
Television Francaise 1 in France and Capital Radio in the United Kingdom.

Even though Japan has been one of the best-performing international markets this
year, those gains are largely in anticipation of potential corporate earnings
improvements rather than a reflection of any real change. The Japanese
government has taken positive steps toward reforming the banking sector. If
these reforms are carried out, we believe they will be positive for the Japanese
equity market. Our strategy in Japan is to focus on individual companies rather
than the market as a whole. We are looking for companies with the strongest
franchises that have the potential to increase earnings consistently over the
next few years. We have found a number of companies that we think fit these
criteria, such as NTT Mobile Communications, a telecommunications company;
Hitachi, a technology company; Takeda Chemical, a pharmaceutical company; and
Chugai Pharmaceutical.

Our positions in the European defense industry have hurt performance. Investors
reacted negatively to the British Aerospace purchase of General Electric Co.
PLC's Marconi defense business. However, we continue to believe that there will
be fewer companies in the industry over the long term and that these companies
should be more efficient and better able to compete globally. We have maintained
positions in British Aerospace as well as in Saab in Sweden, both of which
appear to us to be well positioned to benefit from this consolidation trend.

European economies are still lagging behind the U.S. economy. Interest rates in
Europe have declined and the euro has weakened, which may stimulate growth by
making exports cheaper. In addition, restructuring efforts that started in
earnest several years ago are beginning to show results, with companies cutting
costs and reducing redundant operations. We expect this restructuring to be
positive for corporate earnings growth. We think the

                                                                               3
<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued
combination of low interest rates, improved earnings, and attractive valuations
on a global basis should support European equity markets.

Markets in Japan have had a strong run so far this year. In general, we believe
Japanese companies have tremendous potential to restructure their businesses to
improve profitability. The question remains whether these companies have the
will to carry out their restructuring plans. We see signs of restructuring
efforts in some companies, and their stock prices have responded favorably. To
move ahead, the Japanese market overall needs to show clear evidence of an
economic rebound and further progress on restructuring.

Finally, if emerging markets can avoid incurring too much debt and can continue
the economic reform process that started as a result of the turmoil in the
markets last year, we think these markets can do reasonably well. Some of them
fell 70% or more from their highs of 1997, so even though they have bounced back
somewhat, we are a long way from where we were before the crash.

MANAGED SECTORS SERIES
For the six months ended June 30, 1999, the Series provided a total return of
15.93%, which compares to returns of 12.23% for the S&P 500 and 14.97% for the
Lipper Capital Appreciation Fund Index (the Lipper Index). The Lipper Index is
an unmanaged, net-asset-value-weighted measure of the largest qualifying mutual
funds with capital appreciation as their investment objective.

The Series' performance in the first half of this year was helped by its
overweightings in the leisure sector, including telecommunications. Early on, we
recognized that we were likely to continue being in a very selective market, in
which only a few stocks would yield above-average rewards to investors. So our
job was to find the companies with the strongest relative earnings growth that
would benefit from the supportive global interest-rate environment.

Driving the performance of the Series was a shift to high-quality growth stocks
- -- companies with strong franchises in dynamically growing markets such as
technology, biotechnology, medical devices, and telecommunications. Some of
these companies included QUALCOMM, Tellabs, Sprint Corp., and Biogen.

We believe the telecommunications industry is one of the most attractive areas
we have been able to identify. Growth is being fueled by global deregulation,
the rapid increase in Internet traffic, and the demand for high-speed data
access. Recognizing these trends, we have identified a number of high-growth
telecom companies that are benefiting from global deregulation and improvements
in technology. These companies fall into two categories. The first is
alternative carriers, such as Global TeleSystems, which is benefiting from the
growth of high-speed data services. The second is cable television and related
telecom equipment companies, which are now viewed as an important part of the
infrastructure for delivering the Internet to the consumer. In this category, we
own companies such as Comcast, MediaOne, and Time Warner.

Searching for companies with strong franchises in high-growth markets has led us
to make a few changes in our holdings during the first half of the year. For
example, we've trimmed back our holdings in energy, basic industries, and
financial services. While we believe that the global economy is recovering, the
pace of that recovery may not be strong enough to support further appreciation
in commodity-based companies. Our concern about the potential for higher
interest rates has caused us to reduce our weighting in financial services, a
sector in which margins generally come under pressure when ratings move up.

While most of our major holdings helped performance, two that did not were Qwest
Communications and Sepracor. Qwest made bids for two other communications
companies. If successful, we believe the growth rate of the newly combined
company would slow significantly. Sepracor also fell sharply as an important
joint venture ran into difficulty. We are hopeful that the stock will deliver
future value to shareholders.

There are several things we are monitoring closely as we strategize for the rest
of the year. Inflation seems subdued; however, we believe the U.S. economy
remains quite robust. Meanwhile, the rest of the world is trying to recover from
recession or is experiencing a recovery. We believe this may be a precursor to
higher interest rates. In a market with high valuations, higher interest rates
do represent a potential risk. Also, in a market characterized by high
valuations, any earnings disappointments can be disastrous. So being on top of
company fundamentals is vital to avoiding earnings shortfalls and capitalizing
on positive earnings surprises. We believe that's where MFS' large team of
dedicated analysts may make the difference.

More than any year in recent memory, we believe that 1999 may be a
stock-picker's market. Why is this? First, in general, valuations are extremely
high, so we must be diligent in finding companies with catalysts for
accelerating growth. Second, the large gains enjoyed by the market over the past
six months need to be digested. We believe only the exceptional stock will beat
the market averages, and it is our job to try to find these exceptional stocks
for our shareholders.

MASSACHUSETTS INVESTORS TRUST SERIES
For the six months ended June 30, 1999, the Series provided a total return of
5.94%, which compares to returns of 10.93% for the average growth and income
fund tracked by Lipper Analytical Services, Inc. and 12.23% for the S&P 500.

<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued

The Series' underweightings in technology and cyclical stocks, combined with
some individual stocks that did not perform well, hurt performance. This Series
seeks a balance between risk and reward. Historically it has been underweighted
in technology because we felt that the sector's potential for risk was higher
than its potential for reward. Unfortunately, with the technology sector's
recent strong performance, this strategy has not worked out in the short term.

Similarly, the Series has been underweighted in cyclicals over the period,
including basic materials, industrial goods and services, and energy. Recently,
many cyclical stocks have performed well; therefore, our underweighting hurt
performance. Although these industries can sometimes offer pockets of strength,
price fluctuations in their stocks are usually volatile. We feel this
characteristic is not in line with the Series' long-term conservative growth
investment style.

The Series' performance also was hurt by several stocks that did not perform
well. An example is Rite Aid, a drug store chain. This year's market has had
wide differences in price-to-earnings ratios between stocks perceived to be
doing well and those perceived not to be doing well. When stocks fail to meet
their earnings projections -- as was the case with this stock -- their prices
tend to suffer precipitous drops. Therefore, we believe the cost of being wrong
is higher today.

Despite the fact that there were individual stocks that hurt performance, there
were some that worked out well for the portfolio. One example is Newell
Rubbermaid, which was added recently. Newell bought Rubbermaid in the first
quarter of this year, and we believe the combined company could have a near
monopoly on a range of consumer staples, including Rolodexes. It also sells home
products such as drapery, hardware, and kitchen accessories. Rubbermaid had a
broad product line that was very popular but its reputation for customer
satisfaction was poor, while Newell brings a strong customer orientation to the
table.

Another example of a good-performing company is Wells Fargo & Co., a
California-based bank. Last fall, it acquired Norwest Corp., a Minnesota-based
bank, bringing together two complementary financial services companies: one with
good cost controls and another with, in our opinion, growth potential.
Furthermore, we have large weightings in companies that we think have more
favorable price-to-earning ratios than those of the market as a whole, including
United Technologies, an aerospace, defense, and building equipment company;
Xerox, an office equipment company; and AlliedSignal, an aerospace, automotive,
and environmental controls company. We think these companies also have
sustainable long-term earnings growth potential.

Telecommunications companies have been positive performers for the Series. Our
holdings include Bell Atlantic, MCI WorldCom, and Sprint's long-distance
telephone group. Sales growth for these companies and for telecommunications
companies in general have been very strong. The Internet has driven demand for
telecommunications services, and both telecommunications equipment and service
companies have performed well as a result.

Although this has been a difficult market for the Series, we will continue to
blend investments in value and growth stocks while trying to manage risk.
Instead of following market trends, we will continue to buy what we think are
reasonably priced companies with promising futures. We believe the best thing we
can do for contract owners is to continue to stick to our investment discipline
- -- investing in high-quality, large-cap, blue-chip companies.

RESEARCH SERIES
For the six months ended June 30, 1999, the Series provided a total return of
9.04%, which compares to a 12.23% return for the S&P 500.

The Series relies on MFS-Registered Trademark- Original Research-SM- to
incorporate the best ideas of our more than 30 equity analysts, who cover
small-, mid-, and large-cap companies; therefore, the portfolio is broadly
diversified. However, the equity market has, until recently, been very narrow,
with 25 to 50 large-cap growth stocks outperforming the rest of the stocks in
the S&P 500. Because the Series is diversified across market capitalizations, it
is not likely to outperform in a market favoring a small group of stocks. As the
market continues to broaden, we expect the Series to benefit.

The Series is underweighted relative to the S&P 500 in stocks with a market
capitalization of $25 billion or more and is overweighted in stocks with all
other capitalizations. We believe stocks with the smaller capitalizations are
selling at more attractive valuations at this time. As the market broadens to
include those smaller capitalization stocks, we think the Series will benefit.

Two industry sectors that have helped performance are financial services and
technology. The Series' gains in financial services largely came from brokerage
and investment banking stocks. Specifically, the Series had a large holding in
Morgan Stanley Dean Witter, which we believe is well managed and experienced in
the markets it serves. Companies around the world are using firms like Morgan
Stanley to help arrange their mergers.

The leading contributors to technology performance were semiconductor companies
such as LSI Logic and Analog Devices. The semiconductor industry was hurt in
1998 by the Asian economic slowdown as well as by the fact that it had built up
its manufacturing capability to a point at which there was too much supply in
some market segments, so prices came down. Now, demand is beginning to catch up
with supply and Asia seems to be recovering, both of which helped semiconductor
companies.

                                                                               5
<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued

The continuing strength of the U.S. economy has supported cyclical companies,
that is, companies whose businesses can benefit from strengthening economic
cycles. For example, the Series has benefited from paper holdings such as
Bowater, the number-two newsprint producer in the world. Bowater recently
acquired a competitor, Avenor, which should give Bowater greater market share as
well as the cost-savings benefits that can come from consolidation. Bowater is
global in scope and has benefited from a favorable supply/demand environment,
which may result in price increases.

A few of the Series' retailing holdings have underperformed. Although the
retailing environment has been very good and Dayton Hudson, the department store
chain, has performed well, the Series was hurt by two stocks, Rite Aid and
CompUSA. We have had a significant position in Rite Aid because we believe that
as the population ages people will use more prescription medicines. However,
Rite Aid opened too many stores in a short period of time and underestimated the
costs of closing old stores. The company also had inventory and accounting
problems. Over the long term, however, we believe Rite Aid will continue to
benefit from increasing prescription sales. CompUSA, meanwhile, is losing
computer and software sales to companies that sell over the telephone or on the
Internet. Also, some business customers, who tend to buy more expensive
equipment, are cutting orders to prepare for any Year 2000 (Y2K) computer
problems. By the end of this year, we think the Y2K issue will largely be
resolved, and we believe the company may perform better.

TOTAL RETURN SERIES
For the six months ended June 30, 1999, the Series provided a total return of
4.98%, which compares to a return of 5.57% for the average balanced fund tracked
by Lipper Analytical Services, Inc. The Series' return also compares to returns
of 12.23% for the S&P 500 and -2.28% for 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.

In the first three months of 1999, the Series was hurt by the continued
underperformance of value stocks compared to growth stocks. Prices of value
stocks reflect the underlying value of companies' assets and earnings, while
prices of growth stocks tend to reflect investors' earnings growth expectations.
Late in March, however, value stocks began to recover, due in part to second-
quarter concerns about inflation. Investors trying to anticipate the effects of
rising inflation and interest rates have bought value stocks and moved out of
growth companies, which have been trading at very high prices relative to their
earnings. Because interest rates help determine the value of future earnings,
any interest-rate increase lowers future earnings value. Therefore, stocks
trading at high prices relative to future earnings become less attractive.

Among industries, we think the energy sector looks particularly attractive. The
price of oil has gone from $12 per barrel to around $19. Also, the major oil
companies cut spending on drilling last year, so any increase in supply this
year should be modest, creating a good supply/demand picture. Two oil companies
we like are BP Amoco, which continues to be a big holding, and Mobil. We believe
these companies are benefiting from the consolidation of the industry. In
addition, the supply/ demand picture for natural gas appears to be quite
favorable. A company that we think may benefit from consolidation and rising gas
prices is Coastal Corp.

Another important sector is financial services. Life insurance companies such as
Lincoln National and Hartford Financial Services Group are benefiting from the
growing popularity of annuities. On the property/casualty side of the business,
premiums are beginning to increase after years of decline. We believe this
should benefit companies such as Chubb and St. Paul.

Companies that have performed well for the Series include AlliedSignal, a
diversified industrial company, and those in the paper industry. AlliedSignal
had some earnings problems last year, but with its planned acquisition of
Honeywell, another diversified industrial company, we believe its future appears
bright. Paper companies have reduced their excess supply and, because global
economies have strengthened, demand for paper has been better than expected. As
a result, we've seen higher prices for such holdings as Weyerhaeuser, Champion,
and International Paper.

In February, we began increasing the Series' stock allocation to around 60% of
assets because we felt prices of value stocks had become attractive, especially
given the big gains in growth stocks over the previous year or so. This increase
has helped the portfolio because the market began turning toward value stocks in
April and May. We also have increased the Series' holdings of bonds maturing in
less than two years. This shortening of duration is a more favorable position in
an environment of rising interest rates. However, we have not changed the basic
makeup of the bond portfolio, keeping about 45% of fixed-income assets in
investment-grade corporates and 30% in U.S. Treasuries to help limit price
volatility.

UTILITIES SERIES
For the six months ended June 30, 1999, the Series provided a total return of
9.99%, which compares to a 7.02% return for the average utility fund tracked by
Lipper Analytical Services, Inc. The Series' return also compares to a 1.17%
return for the Standard & Poor's Utility Index, an unmanaged,
market-capitalization-weighted, total return index of all utility stocks in the
S&P 500.

MANAGEMENT REVIEW AND OUTLOOK -- continued

The Series has benefited from consolidation or attempted acquisitions among
several of its top holdings. For example, Frontier Corp., which was the former
Rochester Telephone, has a new management and a new strategy. The company is
focusing on the growth sectors of telecommunications. Two rival companies,
Global Crossing and Qwest Communications, engaged in a bidding war over
Frontier, and Frontier's stock price rose as a result. Another successful
telecommunications position has been MediaOne. Like many cable companies, it
faced difficult regulation and the consequences of overspending. Now, however,
the regulatory picture has improved, and MediaOne's spending is paying off. As a
result, MediaOne has been the object of multiple buyout offers, and its stock
price has risen based on its proposed acquisition by AT&T.

Although consolidation has benefited the Series' telecommunications holdings,
these stocks generally have been performing better than utility stocks for some
time. We believe this pattern will continue for the near future because demand
in this sector is continually increasing. We are being selective, however. We
bought Cincinnati Bell, a local telecommunications company which is branching
out, near the beginning of the year, and it has performed well due to strong
demand for its cellular and Internet services.

The Series' weighting has increased in the natural gas sector, another area that
has experienced consolidation. For example, El Paso Energy's takeover of Sonat
last spring created one of the country's largest natural gas pipeline companies.
The Series owns both Sonat and El Paso, and their stock prices have increased
since the deal was announced. Enron Corp., which is the biggest player in the
trading of both natural gas and electricity, also has benefited from its
leadership position in energy outsourcing and has performed well.

Another holding is Atmos Energy, a local distribution company (LDC). It is in
nine different states and is probably one of the best-run LDCs in our view. The
company has made some recent acquisitions that have nearly doubled its growth
rate. Peco Energy has helped us. Thanks to increased earnings, it is one of the
few electric utilities that had a good first quarter.

We believe the supply/demand outlook for natural gas will improve, perhaps by
this fall. The past two winters have been unseasonably warm, which has cut
demand. However, we believe a return to any sort of normal weather pattern
should help this industry. As companies begin to fill gas storage facilities, a
tight market could be created, which would benefit companies like Coastal Corp.,
a pipeline, exploration, and production company. A stronger natural gas market
also would benefit other companies in the Series, such as El Paso and Williams.

NOTES TO PERFORMANCE SUMMARY

All results are historical and assume the reinvestment of dividends and capital
gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND UNITS, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE
IS NO GUARANTEE OF FUTURE RESULTS. Performance results reflect any applicable
expense subsidies and waivers, without which the results would have been less
favorable. Subsidies and waivers may be rescinded at any time. See the
prospectus for details.

RETURNS SHOWN DO NOT REFLECT THE DEDUCTION OF THE MORTALITY AND EXPENSE RISK
CHARGES AND ADMINISTRATION FEES. PLEASE REFER TO THE ANNUITY PRODUCT'S ANNUAL
REPORT FOR PERFORMANCE THAT REFLECTS THE DEDUCTION OF THE FEES AND CHARGES
IMPOSED BY INSURANCE COMPANY SEPARATE ACCOUNTS.

(1) Investing in small or emerging growth companies involves greater risk than
    is customarily associated with more established companies. These risks may
    increase unit price volatility. See the prospectus for details.

(2) The Series may focus its investments in certain sectors, thereby increasing
    its vulnerability to any single economic, political, or regulatory
    development. See the prospectus for details.

(3) Investments in foreign and emerging market securities may provide superior
    returns but also involve greater risk than U.S. investments. Investments in
    foreign and emerging market securities may be favorably or unfavorably
    affected by changes in interest rates and currency exchange rates, market
    conditions and the economic and political conditions of the countries where
    investments are made. These risks may increase unit price volatility. See
    the prospectus for details.

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-six separate Series (the Series) of
shares: Bond Series, Capital Appreciation Series*, Capital Opportunities Series,
Emerging Growth 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*,
MFS/Foreign & Colonial Emerging Markets Equity Series, Money Market Series, New
Discovery Series, Research Series*, Research Growth and Income Series, Research
International Series, Strategic Income Series, Total Return Series*, Utilities
Series*, and Zero Coupon Series 2000 Portfolio. The Global Growth Series,
Managed Sectors Series, and Utilities Series 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 Trust benefits under variable contracts issued by such companies. Effective
May 1, 1999, the World Growth Series and Conservative Growth Series changed
their names to the Global Growth Series and Massachusetts Investors Trust
Series, respectively.

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. 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. Futures contracts listed on commodities exchanges
are reported at market value using closing settlement prices. Over-the-counter
currency options are valued through the use of a pricing model which takes into
account foreign currency exchange spot and forward rates, implied volatility,
and short-term repurchase rates. Securities for which there are no such
quotations or valuations are valued at fair value as determined in good faith by
the Trustees.

Futures Contracts - Certain Series of the Trust may enter into futures contracts
for the delayed delivery of securities of currency, or contracts based on
financial indices at a fixed price on a future date. In entering such contracts,
the Series are 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 the 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. The Series'
investment in futures contracts is designed to hedge against anticipated future
changes in interest or exchange rates or securities prices. Certain Series of
the Trust may enter into futures contracts for non-hedging purposes. Investments
in interest rate futures for purposes other than hedging may be made to modify
the duration of the portfolio without incurring the additional transaction costs
involved in buying and selling the underlying securities. Investments in
currency futures for purposes other than hedging may be made to change the
Series' relative position in one or more currencies without buying and selling
portfolio assets. Investment in equity index contracts or contracts on related
options for purposes other than hedging, may be made when the Series has cash on
hand and wishes to participate in anticipated market appreciation while the cash
is being invested. Should interest or exchange rates or securities prices move
unexpectedly, the Series may not achieve the anticipated benefits of the futures
contracts and may realize a loss.

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 - Certain Series of the Trust may lend their securities to member
banks of the Federal Reserve System and to member firms of the New York Stock
Exchange or subsidiaries thereof. State Street Bank and Trust Company ("State
Street"), as agent, loans the securities to certain brokers (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

                                                                              51

indemnification against Borrower default. The Series bears the risk of loss with
respect to the investment of cash collateral.

collateral, and cash held as collateral were as follows:

Cash collateral is invested in short-term securities, which are included in the
Portfolio of Investments. 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 State Street in its capacity as lending agent. On loans
collateralized by U.S. Treasury securities, a fee is received from the Borrower,
and is allocated between the Series and State Street. 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.

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. 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, 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 calculated as a percentage of
the Series' month end net assets. The fee is reduced according to an arrangement
that measures the value of cash deposited with the custodian by the Series. This
amount is 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 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 requires that 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, which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or net realized gains. At
December 31, 1998, the Managed Sectors Series, for federal income tax purposes,
had a capital loss carry forward of $475,355 which may be applied against any
net taxable realized gains of each succeeding year until the earlier of its
utilization or expiration on December 31, 2006.

(3) Transactions with Affiliates
Investment Adviser - The Trust has an investment advisory agreement with
Massachusetts Financial Services Company (MFS), an indirect subsidiary of Sun
Life Assurance Company of Canada (U.S.), to provide overall investment advisory
and administrative services, and general office facilities. Investment advisory
fees are computed daily and paid monthly at an annual rate based on a percentage
of each Series' average daily net assets.

participating funds at the end of each quarter. The commitment fees allocated to
each Series for the six months ended June 30, 1999, are as follows:

Each Series and other affiliated funds also participate in a $20 million
uncommitted, unsecured line of credit provided by "the custodian" or "a
custodian bank" under a line of credit agreement. Borrowings may be made to
temporarily finance the purchase of securities, the redemption of shares, or
emergency expenses.

Each Series had no significant borrowings during the period.

(7) Financial Instruments
Certain Series of the Trust may trade financial instruments with
off-balance-sheet risk in the normal course of their investing activities in
order to manage exposure to market risks such as interest rates and foreign
currency exchange rates. These financial instruments include futures contracts.
The notional or contractual amounts of these instruments represent the
investment the Series has in particular classes of financial instruments and
does not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transactions are considered. As of June 30,
1999, none of the Series had outstanding futures contracts.

(8) 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 between 0% and 15% of the Series' net assets. At
June 30, 1999, the Emerging Growth Series, Global Growth Series and Total Return
Series owned the following restricted securities (constituting 0.04%, 0.01% and
0.02% of the net assets of each Series, respectively) which may not be publicly
sold without registration under the Securities Act of 1933. The 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, are valued at fair value as determined in good
faith by the Trustees.

                      MFS' YEAR 2000 READINESS DISCLOSURE

       MFS Investment Management-Registered Trademark-, as an investment
       adviser and on behalf of the MFS portfolios, is committed to the
       effective use of technology in managing our portfolio investments,
       delivering high-quality service to MFS shareholders and contract
       owners, retirement plan participants, and MFS' institutional
       clients, and supporting the financial advisers who sell our
       products. With that in mind, we created a separately funded Year
       2000 Program Management Office in 1996 composed of a specialized
       staff reporting directly to MFS senior management.

       The Year 2000 (Y2K) problem arises because calendar-year fields in
       computers and software applications traditionally have used
       two-digit codes so that, for example, the year 1998 is coded as
       "98," with the "19" being implied. In the year 2000, unless
       necessary corrections have been made, computer applications may
       assume "00" refers to 1900 rather than 2000, thus resulting in
       systems failures or miscalculations. To address this issue, our
       team of dedicated business and technology managers, working with
       outside experts, is taking steps to ascertain the Y2K readiness of
       MFS' internal systems and is working with our external systems
       vendors to determine whether they expect their systems to be
       ready.

       MFS recognizes that fund shareholders, contract owners and
       institutional clients also are concerned about whether the
       companies whose securities are held in their portfolios are
       addressing Y2K issues. As part of the MFS-Registered Trademark-
       Original Research-SM- process of evaluating portfolio investments,
       one of the many relevant factors that MFS' portfolio managers and
       research analysts may consider is a company's Y2K readiness. Each
       year, MFS' research analysts and portfolio managers conduct more
       than 1,000 on-site meetings with companies whose securities are,
       or may be, held in fund and client portfolios, and host an
       additional 1,500 meetings at MFS' headquarters. When assessing the
       Y2K readiness of these companies, MFS' research analysts and
       portfolio managers may rely upon discussions at these meetings as
       well as SEC disclosure documents and third-party reports.

       Y2K readiness is an enormously complex, worldwide issue. No
       company or institution can guarantee that it will be unaffected by
       the Y2K issue. While MFS is taking significant steps to protect
       the integrity of its internal systems, there can be no assurance
       that these steps will be sufficient to avoid any adverse impact on
       MFS, shareholders of MFS funds, participants in retirement plans
       administered by MFS, or MFS' institutional clients.

       If you have further questions regarding MFS' Year 2000 Readiness
       Program, please visit our Web site at www.mfs.com or contact the
       MFS Year 2000 Program Management Office by e-mail at [email protected]

                         YEAR 2000 READINESS DISCLOSURE

                                     [LOGO]

       The potential hazard of computers having difficulty dealing with
       the year 2000 has been widely reported in the media. Essentially,
       the "Y2K" problem stems from some computer software being written
       in a way that will handle only two digits of a year rather than
       the full four digits. This becomes a problem when 2000 is
       perceived as simply "00", with the result that the computer
       software interprets the date as 1900 rather than 2000.

       Sun Life began working on this problem in 1995 when a Company
       strategy for dealing with the issue was approved by systems
       management. It was apparent that effective support from senior
       management was a key component to successfully correcting Sun
       Life's systems. For this reason, in early 1996 Sun Life's Chairman
       and CEO delivered a clear mandate to make Y2K a top priority.
       Since that time project teams have inventoried and assessed nearly
       2000 systems around the Company.

       The vast majority of Sun Life's systems have already been tested,
       and, based on these tests, have been certified as compliant. The
       relatively few remaining systems will be certified compliant
       during the course of 1999. Even though relatively few Y2K bugs
       were actually found during analysis, it has been Sun Life's policy
       to test every system before it can be certified as compliant. The
       price tag for this massive project has been steep -- over $100
       million (Cdn). However, we consider the money well spent when it
       means that Sun Life can move into the year 2000 and beyond
       confident that our systems will support Sun Life's position as a
       leader in the financial services industry.

       THE PRECEDING IS A YEAR 2000 READINESS DISCLOSURE PURSUANT TO THE
       YEAR 2000 READINESS DISCLOSURE ACT ENACTED BY THE UNITED STATES
       CONGRESS ON OCTOBER 19, 1998.
