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

Bond Series

For the six months ended June 30, 2000, the series provided a total return of
3.12%, which compares to a 2.24% return for the average corporate-debt
"BBB"-rated portfolio tracked by Lipper Inc., an independent firm that reports
performance. The series' return also compares to a 4.18% return over the same
period for the Lehman Brothers Government/Corporate Bond Index (the Lehman
Index). The Lehman Index is an unmanaged, market-value-weighted index of U.S.
Treasury and government-agency securities (excluding mortgage-backed securities)
and investment-grade debt obligations of domestic corporations. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

The recent period was historically tumultuous for the investment-grade corporate
bond market. Most of the problems were the result of company-specific issues.
There also has been much less liquidity in the corporate market over the past
few years, a residual effect of the credit problems that plagued corporate bonds
starting in 1998 when Russia surprisingly defaulted on its debt obligations.
Historically, "vulture" investors on Wall Street provided buyers for the debt
issues of companies that hit a hard patch, but that hasn't been the case
recently. In addition, the high-yield market has experienced net outflows, so
there hasn't been capital available to absorb some of these credit problems from
that traditional source.

The overall credit quality of the corporate market has been deteriorating as
well. While we've seen stock price growth in the technology sector, companies
there have been carrying very little debt. Elsewhere, despite strong economic
growth in the United States, the stocks of many companies -- especially those in
cyclical sectors -- have been distressed to the point where company managements
have come under increasing pressure to enhance value for shareholders.
Consequently, we have found that many have issued more debt to finance mergers
and acquisitions or share buyback programs, which help the shareholder but hurt
the bondholder. We think these kinds of moves have weakened many companies'
credit fundamentals and caused a number of credit downgrades.

In response to this difficult climate, we increased the overall credit quality
of the portfolio. In addition, we reduced investments in domestic corporate
industrial bonds because they remain vulnerable to weakening credit
fundamentals. Instead, we focused on sectors that are not as prone to the risk
that management will issue more debt to finance leveraged buyouts or share
buybacks. That has translated into increased exposure to sectors like media and
telecommunications. For example, we retained our investment in Time Warner,
whose merger with America Online is creating a powerful conglomerate that we
believe should eventually experience a credit upgrade. We found other
opportunities in British Sky Broadcasting, a satellite network in Europe that we
think has tremendous growth prospects, and Seagram, which is making a transition
from a spirits company to an entertainment conglomerate. We also invested about
6% of the series in Yankee bonds, which are dollar-denominated bonds issued in
the United States by foreign countries, such as Israel, that have
investment-grade credit ratings.

Investments that worked out well for the series included a number of our
higher-quality junk bonds, such as Comcast Corporation, which crossed over into
investment-grade status, appreciating significantly in the process. The credit
upgrades enjoyed by emerging market countries South Korea and Mexico also helped
the series' performance.

We restructured the series' holdings in U.S. Treasuries in response to the
Federal Reserve Board's (the Fed's) program of interest-rate hikes. (Principal
value and interest on Treasury securities are guaranteed by the U.S. government
if held to maturity.) The Fed's actions caused short-term rates to back up
significantly, while longer-term rates remained relatively stable. As a result,
the yield curve -- a representation of the difference between short- and
long-term rates -- flattened, then inverted, with short-term rates actually
reaching higher levels than long-term yields. We felt the best way to take
advantage of this situation was to pursue a barbell strategy by investing some
of our Treasury holdings on the long end of the curve, some on the short, and
very little in between. As a result, the series was not affected by the sharpest
price declines that occurred in the intermediate part of the yield curve.

Looking ahead, we believe recent indicators may be pointing to a slowing economy
in response to the Fed's program of interest rate increases. In this kind of
environment, we think interest rates could begin trending downward as soon as
late 2000. There appears to be very little evidence of a protracted struggle
against inflation. That opinion is further strengthened by our discussions with
company managements who say that they have very little pricing power. For our
part, we intend to continue moving our corporate holdings to bonds with shorter
maturities because they are less prone to price volatility. At the same time, we
anticipate extending the Treasury duration in the portfolio (duration is an
indicator of interest-rate sensitivity) to try to take advantage of potential
declines in long-term interest rates.

Emerging Markets Equity Series

For the six months ended June 30, 2000, the series provided a total return of
-4.89%, which compares to returns over the same period of -7.99% and -9.59%,
respectively, for the series' benchmarks, the Morgan Stanley Capital
International (MSCI) Emerging Markets Free (EMF) Index, a broad, unmanaged,
market-capitalization-weighted index of equities in emerging markets, and the
Lipper Emerging Markets Portfolios Index (the Lipper Index). The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

During the first quarter of the period, the series benefited from an impressive
global economic recovery that spilled over into most emerging markets. Our
holdings in Southeast Asia and Latin America produced stellar results. Year to
date, however, we've


2
<PAGE>


Management Review and Outlook -- continued

seen a lot of correlation between the performance of the U.S. market and
emerging markets. As investors became increasingly concerned about stock
valuations and whether future earnings could support them, we witnessed
broad-based selling in emerging markets. Technology and telecommunications
stocks, two of the largest sector weightings for the series, came under the most
pressure. Unfortunately, some of the more liquid markets, such as South Korea
and Taiwan where the portfolio was overweighted relative to its benchmarks, were
hardest hit.

Early in 2000, we began to reduce our positions in South Korea because many of
these stocks reached our price targets, and we believed they were fairly valued
following impressive results in 1999. In India, we added a number of technology,
telecommunications, and financial services stocks in an effort to capitalize on
what we saw as rapid growth at these companies. As prices came down in Southeast
Asian markets in the second quarter, we began to increase our exposure to what
we believe are high-quality companies selling at reasonable valuations,
especially in the telecom industry. We believe, to a large extent, that many
emerging market telecom companies -- through their wireless, Internet, and data
transmission services -- have transformed themselves from slow-growth utilities
into fast-growing, dynamic companies. In addition to large, established telecom
companies, we've focused on new telecom entrants that possess innovative product
lines and dynamic business plans.

Our stock selection across a broad range of countries helped performance. A
particularly strong performer was Teva Pharmaceutical, an Israeli biotechnology
and health care company whose stock price surged dramatically on strong sales of
its multiple sclerosis treatment Copaxone and recent approval by the U.S. Food
and Drug Administration of Nabumetone, its generic form of arthritis treatment.
Other strong contributors and significant holdings in the series were Li & Fung
Ltd. and Dimension Data. In Hong Kong, Li & Fung benefited from surging sales
and strong demand for apparel manufacturing outsourcing due to the rebounding
Southeast Asian economy. South African computer services firm Dimension Data
boosted the series' performance as the company experienced strong demand for its
information technology services, which led to favorable revenue and earnings
growth.

Recently, we've increased the series' holdings in Taiwan because we've located
what we think are some compelling growth opportunities in this country. We
believe Taiwan is a very important emerging market that is slowly becoming more
open to investors as it enhances its stock market technology and improves its
financial reporting standards. We think these trends should help cash flows into
this market. More importantly, some of the most innovative and competitive
semiconductor companies in the world are located in Taiwan. In our view,
companies such as Taiwan Semiconductor are well positioned to benefit from the
global trend of increased spending on technology and the tremendous growth
potential of the Internet and telecommunications.

Ironically, some of the industries where we see the strongest prospects for
future earnings growth have detracted from performance in recent months, namely,
technology and telecommunications. Primarily due to concerns about high
valuations, investors began to unload shares in these sectors. Along with many
tech and telecom companies, Korea Telecom, Telefonos de Mexico, and Hyundai
Electronics have experienced weakness in recent months. However, we believe the
fundamental business outlooks for these companies are still very strong and
their valuations have become more attractive.

In general, our outlook for emerging markets is positive. The prospects for
global economic growth are favorable, and we expect this growth to benefit a
wide range of our holdings. We also believe emerging market stock valuations are
very attractive, especially given the recent pullback. In addition, the
anticipated growth rates and earnings outlooks for emerging market equities
appear compelling compared to those of the United States and other developed
economies. From our standpoint, these markets provide some of the most
interesting growth opportunities in the world, and the positive trends we've
outlined could support investor interest in the region.

Global Asset Allocation Series

For the six months ended June 30, 2000, the series provided a total return of
2.71%, which compares to the following returns for the series' benchmarks:
-0.42% for the Standard & Poor's 500 Composite Index (the S&P 500), a popular,
unmanaged index of common stock total return performance; -3.95% for the Morgan
Stanley Capital International (MSCI) Europe, Asia, Far East (EAFE) Index, an
unmanaged index of international stocks; 3.99% for the Lehman Brothers Aggregate
Bond Index, an index of government and corporate bonds including U.S. Treasury,
agency, and corporate bond issues and mortgage-backed securities; and -1.89% for
the J. P. Morgan Non-Dollar Government Bond Index, an index of international
bonds. The series performance includes the reinvestment of any distributions but
does not reflect any applicable contract or surrender charges.

The series' strategy of utilizing quantitative measures and in-depth fundamental
analysis to create a well-diversified portfolio of stocks and bonds worked well
during the past six-month period. To set the overall asset allocation, we use
MFS proprietary quantitative models to evaluate each market's current valuations
and economic strength compared to historical levels. Based on that information,
we then allocate the portfolio to focus on growing economies and undervalued
markets that we believe have encouraging prospects. Once we set an overall asset
allocation, however, our stock and bond picking is based on extensive bottom-up
research and analysis.

During the past few years, diversification has generally hurt investors'
returns. However, given the exceptional strength of the U.S. equity market over
the past 10 years and the prospects for slower growth in the United States, we
think the environment is ideal for a broadening of global market strength. We
are currently finding many attractive growth opportunities in Europe, Japan, and
the United States across a wide-range of industries. In addition, corporate
restructuring and industry consolidation continues to spread worldwide, which
could spur additional interest in international equities. As a result, we
believe one of the best ways to participate in these international opportunities
and global economic growth is to maintain a well-diversified portfolio of
domestic and foreign investments.

On the equity side, our focus on valuations, fundamental business strengths,
economic variables such as interest rates, and risk-adjusted total returns led
us to slightly underweight the series' exposure to equities relative to our
benchmarks. Despite a period of high volatility and weakness for stocks, this
strategy worked to our advantage. The series' overweighting in Japanese stocks
relative to the MSCI EAFE Index also continued to be a major theme affecting
performance. Early in the period, performance was aided by superior returns from
the series' positions in Japanese tech and telecom stocks such as Hitachi,
Canon, and NTT Mobile. The portfolio received a similar boost from U.S. and
European telecom and tech stocks such as


                                                                               3
<PAGE>


Management Review and Outlook -- continued

Corning, Vodafone AirTouch, Micron Technology, Oracle, and Cisco.

During the second quarter of 2000, however, concerns about valuations and the
potential of a slowdown in global economic growth caused a correction in
technology and telecommunications stocks in many countries. Persistent selling
pressures reduced much of the performance achieved by these stocks during the
first three months of the period.

On the bond side, our fixed-income holdings provided stability and generally
positive returns during a period of severe volatility for stocks. For the first
time in a few years, our bond positions outperformed the equity component of the
portfolio. Our decision to overweight the series in U.S. Treasuries and
high-quality foreign government bonds aided performance, and our longer-term
Treasuries performed particularly well during the six-month period while
short-term Treasuries suffered in the rising interest-rate environment.
(Principal value and interest on Treasury securities are guaranteed by the U.S.
government if held to maturity.) Long-term European government bonds also
outperformed their shorter-maturity counterparts, and, again, we benefited from
positioning the series in longer-term European government securities. While our
exposure to emerging market bonds was marginal, our overweighting in these
securities relative to the series' benchmarks generally contributed to total
return.

Looking forward, we'll continue to emphasize our disciplined quantitative
process that controls our top-level allocation and helps create a
well-diversified portfolio. Once our quantitative models provide us with a
macroeconomic view of the general health and attractiveness of various regions,
countries, and industries, our fundamental research begins. As always, our focus
is to try to balance risk in the portfolio by holding what we believe is the
best mix of stocks and bonds. At the same time, our goal is to find the
companies and securities that we think offer attractive valuations and growth
opportunities.

Global Governments Series

For the six months ended June 30, 2000, the series provided a total return of
-0.82%, which compares to a return of 0.03% over the same period for the series'
benchmark, the Salomon Brothers World Government Bond Index (the Salomon Index).
The Salomon Index is an unmanaged index of complete universes of government
bonds with remaining maturities of at least five years. The series performance
includes the reinvestment of any distributions but does not reflect any
applicable contract or surrender charges.

Despite strong economic growth and tightening of monetary policy (raising
interest rates), the U.S. bond market remained one of the strongest and
best-performing fixed-income markets year to date. The strength in the market
reflects investor confidence that the U.S. Federal Reserve Board (the Fed) is
effectively guiding the economy to a soft landing -- slowing growth enough to
control inflationary pressure without sending the economy into recession. The
market has also been supported by the reduced supply of government bonds as a
result of the budget surplus and the Treasury buyback program. Almost all the
European markets underperformed the United States as the weaker euro and growing
inflation concerns unnerved potential investors. The market in Japan also
underperformed due to concerns over the potential of their central bank
abandoning the current zero interest-rate policy (interest rates and bond prices
move in opposite directions).

The series was helped by having overweighted positions in the U.S. bond market
and being underweighted both in Europe and Japan relative to the Salomon Index.
Recently, we started to purchase a number of sovereign Yankee bonds
(dollar-dominated bonds issued in the United States by foreign governments), The
yields on these bonds looked very attractive. In addition, given their relative
safety and favorable outlook for price appreciation, we have overweighted the
series relative to the index in these securities.

During the past six months, especially during the first quarter, the series'
nominal and relative performance was hurt by the rapid depreciation of the euro.
Longer term, we still believe that the euro will strengthen, partially due to
signs that the European economies are beginning to grow more rapidly than the
United States. This growth may cause the European Central Bank to raise interest
rates further, while the Fed is expected to adopt a more neutral monetary
policy. Consequently, higher interest rates in Europe could attract more
investors and increase cash flows into the beleagured euro.

If the Fed achieves a soft landing -- which we believe is the likely scenario --
U.S. Treasuries should outperform European and Japanese bonds. (Principal value
and interest on Treasury securities are guaranteed by the U.S. government if
held to maturity.) As a result, we plan to continue to position the portfolio
defensively while at the same time taking advantage of attractively priced
international bonds and the improving interest-rate conditions in the United
States. By increasing the series' duration (sensitivity to interest rates) in
U.S. government securities, we may achieve more price appreciation and higher
yields.

Global Total Return Series

For the six months ended June 30, 2000, the series provided a total return of
2.34%, which compares to a 0.39% return for the average global flexible
portfolio tracked by Lipper Inc. The series' return also compares to returns
over the same period of 1.41% and 1.61%, respectively, for the series'
benchmarks, the Lipper Global Flexible Portfolio Index and a customized
benchmark made up of 60% of the Morgan Stanley Capital International (MSCI)
World Index and 40% of the J.P. Morgan Global Government Bond Index (the Morgan
Index). The Lipper portfolio indices are unmanaged, net-asset-value-weighted
indices of the largest qualifying portfolios within their respective investment
objectives, adjusted for the reinvestment of capital gains distributions and
income dividends. The MSCI World Index is a broad, unmanaged index of global
equities. The Morgan Index is an aggregate of actively traded government bonds
issued by 13 countries, including the United States, with remaining maturities
of at least one year. The series performance includes the reinvestment of any
distributions but does not reflect any applicable contract or surrender charges.

Our investment strategy, which leans more toward value, or what we sometimes
refer to as seeking value among growth stocks, had a significant effect on the
series' performance. Additionally, unlike other flexible global fund managers
who we feel may maintain a larger exposure to equities, we follow a disciplined
asset allocation strategy toward managing this portfolio. Accordingly, the
series' typical asset allocation has remained consistent, ranging from 55% to
65% in equities and 35% to 45% in bonds and short-term investments. We believe
our strategy offers investors the ability to pursue long-term growth while also
helping to reduce risk and volatility through broad diversification across
different asset classes. However, similar to what we


4
<PAGE>


Management Review and Outlook -- continued

experienced in the United States, value-oriented stocks in most developed
countries have tended to underperform the high-tech growth stocks that dominated
the market during the first quarter of the year. During the second quarter of
2000, we saw investors shift assets into more value-oriented stocks, which
provided a significant boost to relative returns.

While the weakness in technology stocks in the second quarter hurt the series'
absolute performance, many of our holdings in this sector held up much better
than the overall group. Japanese technology conglomerates such as Canon and Rohm
represented large positions in the portfolio and provided favorable results. We
believe that their product lines offer compelling competitive advantages, their
earnings outlooks appear bright, and their management teams have adopted
Western-style strategies of creating shareholder value through effective
cost-cutting measures, greater efficiency, and aggressive marketing.

We've talked about our significant holding in the German telecommunications
company Mannesmann in previous reports, and since being acquired by Vodafone
AirTouch, it has become the largest equity holding in the portfolio and has
provided exceptional performance for the series. We're strong believers in the
combined company's ability to remain a dominant global provider of telecom
services. As the world's largest provider of wireless communications, we believe
it's also well positioned to outperform in one of the fastest-growing sectors of
the global economy. Other stocks that contributed favorably to total return were
Television Francaise, Compass Group, and Skandia. Television Francaise, one of
the leading television station operators in France, benefited from the
impressive acceleration in advertising spending due to the high-tech boom that
has embraced continental Europe. British catering company Compass Group is a
classic example of business outsourcing, an area that has experienced tremendous
growth. We believe Compass' business model of operating the kitchens and
cafeterias of established companies is an excellent concept, and it's quickly
becoming a world leader in the corporate catering business due to its low-cost
structure and strong management. Skandia, a Swedish insurance firm, also
performed strongly. We believe European investors have become increasingly
focused on personal investing and retirement planning, which has added
considerably to Skandia's bottom line.

On the negative side, our holding in Gannett Co. was a disappointment during the
period. Despite what we believe were strong business fundamentals and a bright
earnings outlook, this diversified newspaper publisher and leading provider of
commercial printing services experienced poor stock performance due to weak
investor sentiment. Gannett was sold from the portfolio. In general, it was a
difficult period for financial services stocks. Our holdings in companies such
as the Federal Home Loan Mortgage Corp. produced lackluster results due to
ongoing concerns about the negative effects of higher interest rates.

In keeping with the series' strategy, our fixed-income holdings were focused on
bonds issued by major governments. During the period, we took a generally
defensive posture by trying to carefully balance the series' sensitivity to
interest rates. That was particularly the case in the United States, where we
were concerned about the prospects of higher interest rates and inflation. In
Europe, it was a bit different. There, we thought the markets had priced in more
inflation than we thought would occur, so we were not as defensive. We favored
issuers in Greece, the United Kingdom, and Germany.

Looking forward, we think the equity market in the United States has some
short-term hurdles to get over before it can resume a steady growth path. We
feel the primary focus for investors right now seems to be how many
interest-rate increases will be necessary to slow U.S. economic growth.
Historically, this type of environment has been very difficult for equities. As
a result, we remain focused on some of the more defensive stocks in the U.S.
market, companies with steady performance and long-term track records.
Additionally, we'll continue to allocate a significant amount of assets to
securities in Europe, Japan, and the United Kingdom, all of which we believe
offer tremendous opportunities for strong stock performance relative to the
United States.

Government Securities Series

For the six months ended June 30, 2000, the series provided a total return of
4.25%, which compares to a 3.95% return for the average U.S. government
portfolio tracked by Lipper Inc. The series' return also compares to a 4.38%
return over the same period for the series' benchmark, the Lehman Brothers
Government/Mortgage Index (the Lehman Index), an unmanaged index of U.S.
Treasury, government-agency, and mortgage-backed securities. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

The fixed-income markets were characterized by uncertainty during the first half
of 2000, as investors tried to figure out how much the Federal Reserve Board
(the Fed) would have to hike short-term interest rates in order to slow growth
and head off inflation. U.S. economic growth continued to surpass expectations
through the winter and spring. To dampen this growth, the Fed has raised the
federal funds rate three more times thus far in 2000 -- bringing it from 5.50%
to 6.50% -- after having raised it three times in 1999. More recently, there
have been some signs that growth might be decelerating to a rate that the Fed
may feel is more consistent with a sustainable but not inflationary pace.
Meanwhile, core inflationary pressures increased only moderately through the
period, despite being prodded upward by significant upswings in the price of
oil. Questions surrounding how much oil price increases would affect other
aspects of the economy exacerbated the market's uncertainty.

The other significant factor that affected fixed-income markets was how the U.S.
government has dealt with its second full fiscal year of budget surplus and the
implications for the Treasury market. With the U.S. Treasury buying back more
than $200 billion in debt this fiscal year and curtailing its auctions of new
issues, the market has tried to come to terms with a dramatic decline in the
supply of Treasury securities. Since all other sectors of the fixed-income
market are priced relative to Treasuries, this situation has made it hard for
bond investors to evaluate the relative values of fixed-income securities and
has created some illiquidity in the market. The value of 30-year Treasuries rose
sharply as buyers needed to compete with each other in order to own them.

At the same time, U.S. government agency securities confronted some difficulties
during the first half of 2000. Specifically, some in Washington called into
question the implicit government backing of agencies such as the Federal Home
Loan Mortgage Corporation (Freddie Mac) and the Federal National Mortgage
Association (Fannie Mae). Concerns revolved around the expansion of agency
activities beyond their original mission and the potential liability to
taxpayers. As a result of this added scrutiny, agency securities underperformed
Treasuries.

Management Review and Outlook -- continued

The series has traditionally maintained an overweighted position in agency
securities because these high-quality assets offer a performance advantage over
Treasuries. (Principal value and interest on Treasury securities are guaranteed
by the U.S. government if held to maturity.) During the past six months, when
Treasuries proved to be the market leaders, the performance of the series was
impacted by its focus on agency securities. The series began the year with a
neutral weighting in mortgage-backed securities, a position that helped the
series because their performance lagged Treasuries somewhat. However, as the
period progressed we added to both the agency and mortgage-backed security
positions because we believe opportunities there offered tremendous long-term
value.

As far as maturity was concerned, we positioned the Treasury portion of the
series to take advantage of increases in short-term rates and decreases in
long-term rates. Specifically, we used a "barbell" strategy, investing the
series in long-term Treasuries on the one hand and very short-term cash
equivalents on the other, with nothing in between. By doing so, the series was
able to benefit on the short end as the Fed raised rates, realize the capital
appreciation offered by long-term Treasuries as their yields fell and prices
rose, and avoid the intermediate-term securities that underperformed. However,
with more confidence that we are nearing the end of this current Fed tightening
cycle, it's likely that we'll move away from the barbell structure, aiming
instead to target specific maturities that we feel offer particular opportunity.

We also kept the series' duration--a measure of its sensitivity to changes in
interest rates--somewhat long, or more sensitive, because of our positive
outlook regarding inflation and the Treasury market.

Looking ahead, we, along with the rest of the market, will try to gauge the
effects of the Fed's monetary policy. Generally, it takes 9 to 18 months to
measure the impact on the economy of Fed rate moves. It could very well be that
the inflationary impact of rising oil prices is behind us and that inflation has
been well contained by the Fed's policy actions. Overall, we feel it should be a
good environment for fixed-income investing. If the Fed hasn't already reached
the end of its rate-hike program, we think it appears to be close. If so, we
should witness growth settling back into a range of around 3.0% to 3.5%, which
the Fed feels is not inflationary. The government continues to run up sizeable
surpluses and to pay down debt. The market seems to have nearly universal
confidence in the Fed's ability to keep inflation from getting out of hand. In
sum, the environment should prove to be very favorable for Treasuries. This
steadier backdrop should also bode well for those sectors that are represented
in the series, such as agencies and mortgage-backed securities.

High Yield Series

For the six months ended June 30, 2000, the series provided a total return of
0.05%, which compares to returns over the same period of -1.21% and -1.91%,
respectively, for the series' benchmarks, the Lehman Brothers High Yield Bond
Index, an unmanaged index of noninvestment-grade corporate debt, and the Lipper
High Yield Bond Index. The series performance includes the reinvestment of any
distributions but does not reflect any applicable contract or surrender charges.

The high-yield market remained plagued by a number of difficulties during most
of the period. First, high-yield portfolios experienced approximately $6.5
billion in outflows this year, which hurt demand for high-yield securities.
Second, credit defaults remained relatively high during the period. Finally,
concerns about inflation and unsustainable economic growth kept investors
nervous about future interest-rate hikes. On a more positive note, we've
recently started to see money flowing back into the high-yield market as the
interest-rate environment has improved and investors are being drawn to some
extremely attractive yields relative to U.S. Treasury and investment-grade
bonds. (Principal value and interest on Treasury securities are guaranteed by
the U.S. government if held to maturity.)

In a market where most high-yield bonds traded lower, the portfolio's
performance compared to its benchmarks benefited from favorable security
selection and industry diversification. During the second quarter of 2000, many
telecommunications and media securities experienced a dramatic selloff along
with the equity market. However, our holdings in these sectors, as well as
holdings in industries such as gaming and industrial manufacturing, held up well
during the period. We maintained our positions in telecom bonds, and it remained
the largest industry exposure in the portfolio. Companies such as Nextel and
Esat Holdings provided a positive contribution to performance. Our position in
Nextel Communications provided steady gains due to persistent strength in
wireless subscriber growth. Our holding in Esat Holdings, another telecom
company, provided a nice boost to performance after it was bought out by British
Telecom. We also weren't afraid to take some profits in energy-company bonds, as
oil and natural gas prices reached historically high levels.

In addition to favorable security selection, our successful avoidance of the
credit problems and bankruptcies that hurt a variety of industries helped the
series' performance. The key to avoiding credit defaults is in-depth research,
and we believe MFS' research capabilities are second to none in the industry.
The High Yield Series is backed by a large group of investment professionals
dedicated exclusively to the high-income market. Our research analysts use a
variety of models to analyze the credit risk and business prospects of the
companies they cover. We carefully measure and manage the underlying financial
stability of each company we hold in the portfolio. Similar to our equity
research, it's an intensive, company-by-company, bottom-up approach. First, we
look at a company's business risks, then we consider the financial risks.
Finally, we look at all the different ways of investing in the company and how
the market is pricing each one of the securities. From this analysis, we try to
pick the bond that offers the best risk-adjusted return. Our holding in U.S. Can
Corp., one of the world's largest aerosol can manufacturers, is a good example
of a bond that met our stringent investment criteria and benefited the series'
performance. The company's management instituted a number of cost-saving
efficiencies in their plants, which improved profitability and cash flow. The
company then began to buy back their bonds resulting in substantial price
appreciation.

After telecommunications, our second largest exposure was in media. Core
holdings included cable television and radio entities such as Charter
Communications, one of the fastest-growing companies in the field. Controlled by
Paul Allen, the co-founder of Microsoft, Charter's valuation has risen following
the increased utilization of cable networks as a means of accessing the
Internet.

In many ways, we view telecom and media as defensive industries that offer
attractive growth and income opportunities. Most people are not going to turn
off their cable or mobile phones if the economy slows down. On the other hand,
some of the big-ticket capital items such as industrial machinery, building

Management Review and Outlook -- continued

materials, and autos may experience a slow down in business and consumer
spending due to higher interest rates. Given the current economic environment,
we like the telecom and media sectors, and we've maintained our significant
exposure to these industries. We've taken some money off the table in some of
the more cyclical industries such as steel and paper packaging, as well as in
general manufacturing. We increased holdings in gaming bonds, which we also view
as a somewhat defensive industry. These securities have gained ground because
there are fewer and fewer regions of the country that permit gaming, and we
believe these companies will continue to produce exceptional earnings and cash
flow growth.

Looking ahead, we're cautiously optimistic regarding a recovery in high-yield
securities. While it's difficult to rule out further volatility given the
uncertain interest-rate environment, the high-income market has been weak for
quite some time now. Yield spreads, the yield difference between
noninvestment-grade debt and Treasuries, have widened significantly during the
past year, making the yields on high-income bonds very attractive relative to
other fixed-income securities in our view. In addition, we believe the economy
will remain healthy and corporate earnings will remain strong. And,
historically, high-yield market has tracked corporate earnings.

International Growth and Income Series

For the six months ended June 30, 2000, the series provided a total return of
3.83%. This compares to returns over the same period of -4.11% and -3.95%,
respectively, for the series' benchmarks, the Lipper International Portfolios
Index (the Lipper Index) and the MSCI EAFE Index. The series performance
includes the reinvestment of any distributions but does not reflect any
applicable contract or surrender charges.

During the first quarter of 2000, portfolios like ours that were not heavily
invested in the technology sector struggled on a relative basis. We held
relatively few tech stocks because we felt that most were overpriced. We believe
this underweighting was a significant factor in our underperformance relative to
our Lipper peers in the beginning of the year. Nevertheless, our view regarding
technology and value investing was vindicated through the second quarter of
2000. We witnessed an overall retrenchment in the tech sector, as exuberance
seemed to give way to doubt as to whether many tech companies could fulfill the
promise reflected in their share prices. We believe the series' underweighting
in tech helped our total return for the six-month period.

During the period, we emphasized companies that we felt had a high probability
of continuing to increase earnings instead of choosing more cyclical stocks,
which tend to rise and fall with changes in the economy. Overall, cyclicals
performed well after having lagged for some time. However, the key to cyclical
investing is pricing power and, while we've seen some indications of higher
prices, inflation does not appear to be in the offing. Therefore we felt that
the market environment would not favor companies with highly cyclical
businesses.

Canon, the Japanese electronics company that offers a broad base of
high-technology products, was one holding that saw good earnings progress. So
was Compass Group, a British company that is the largest caterer in the world,
running food services for hospitals, schools, and companies. Compass is
presently considering merging with another company, and we think it has proven
ability to increase its earnings unimpaired.

Over the past six months, the series' stake in Japan declined a bit because some
companies, such as Sony, were taking longer to turn around than we expected.
However, our long-term view on Japan and well-managed Japanese companies like
Sony is very bullish. Following the lead of companies in the United States and
Europe, Japanese firms are now streamlining in fundamentally important ways. For
example, Japanese corporations have historically engaged in cross-ownership --
holding shares in each others' companies. While this is a time-honored way of
doing business in Japan, it is a very poor use of capital. Now, Japanese
corporations are working to eliminate these kinds of business practices,
focusing instead on more shareholder-friendly strategies such as restructuring,
stock buybacks, and selling off businesses to focus on core operations.

European companies accounted for about two-thirds of the series' holdings at the
beginning of the period, roughly in line with the European portion of the MSCI
EAFE Index. However, we reduced our European holdings by the end of June. While
valuations had reached high levels and some economies had begun to soften, this
decline was not the result of an overall negative view of European stocks.
Instead, it was the consequence of buying and selling decisions at the company
level. We are bottom-up stock pickers, choosing companies for the portfolio
based on their individual prospects. In terms of country weightings, companies
from smaller European nations currently are well represented, as were French
companies during the course of the year. Our allocation to German companies
declined, but that was largely due to the acquisition of Mannesmann by British
firm Vodafone AirTouch.

Rohm, a Japanese electronic devices manufacturer, performed well as it continued
to increase earnings. The French company STMicroelectronics benefited from its
niche as the only European semiconductor manufacturer. Television Francaise was
helped by the strong French economy and resulting excellent advertising
backdrop. Finally, Nortel Networks, a telecommunications equipment provider,
proved to be a winner after its successful spin-off from Bell Canada.

Conversely, Akzo Nobel, an economically sensitive chemical company, proved to be
one of the disappointments. So did Canadian National Railway, which suffered
from fears of an imminent economic slowdown. Diageo, a British consumer goods
company that owns Pillsbury, Guinness, and Burger King, lagged due to general
investor disinterest in this sector.

Please remember that we are stock pickers, not economists. When we look to the
horizon, though, we note that consumer spending is helping to sustain vibrant
economic growth in the United States. We believe this growth should help buoy
the U.S. stock market for some time. It also should help support advances in the
European stock market. We think that Japan could benefit as well, but, because
of its economic problems, has the toughest row to hoe.

Due to its growth over the past decade, the U.S. stock market currently accounts
for a very large percentage of the world's total stock holdings. We believe that
that value is unwarranted when weighed against the significant amount of
business taking place around the rest of the world. As a result, we think
foreign markets should catch up over the longer term. That doesn't mean that the
U.S. market will necessarily decline, but it may tread water while stocks
overseas post higher gains.

Money Market Series

The series seeks as high a level of current income as is considered consistent
with the preservation of capital and liquidity by investing in short-term money
market securities

issued or guaranteed by the U.S. Treasury, its agencies, or instrumentalities of
the U.S. government, as well as in the highest-quality corporate and bank
issues, in order to minimize credit risk.

Despite some signs of moderating economic growth in the second quarter of 2000,
the U.S. economy continued to grow steadily and unemployment fell to 30-year
lows. Historically, these conditions have caused inflation to accelerate, and
the Federal Reserve Board (the Fed) moved to contain the inflationary pressures
that usually accompany this backdrop.

We don't believe the possibility of future interest-rate hikes can be ruled out.
As a result, we've structured the portfolio with a relatively short maturity and
targeted 36 days for the average maturity of the series' holdings.

On June 30, 2000, approximately 85% of the portfolio was invested in
high-quality commercial paper, with the balance invested in U.S. government or
government-guaranteed issues.

Investments in the series are not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although the series seeks
to preserve the value at $1.00 per unit, it is possible to lose money by
investing in the series.

Strategic Income Series

For the six months ended June 30, 2000, the series provided a total return of
1.65%, which compares to a 0.43% return for the average multisector income
portfolio tracked by Lipper Inc. The series' return also compares to the
following returns over the same period for the series' benchmarks: 4.18% for the
Lehman Brothers Government/Corporate Bond Index (the Lehman Index), 0.03% for
the Salomon Brothers World Government Bond Index (the Salomon Index), and -1.21%
for the Lehman Brothers High Yield Bond Index. The series performance includes
the reinvestment of any distributions but does not reflect any applicable
contract or surrender charges.

In relation to most of our benchmarks, the series' holdings performed well
across the six sectors in which we invest: U.S. government and mortgage bonds,
U.S. high-grade corporates, U.S. high-yield corporates, international developed
countries, emerging markets, and convertible bonds and preferred stocks. We
believe our outperformance resulted from our strategy of employing both sector
diversification and flexibility in managing the series. We continually
reallocate assets among the various sectors in response to, or in anticipation
of, global events, taking advantage of what we perceive to be opportunities
throughout the world.

Our bottom-up MFS Original Research[RegTM] process plays a key role in helping
us manage the portfolio because our approach is to try to pick bonds issued by
good companies and good countries, period; none of our sectors is meant to
replicate an index. In the balance of this report, we'll review how each sector
contributed to performance and give you our outlook for individual sectors.

In the U.S. government sector, which includes U.S. Treasury and mortgage-backed
securities, we have remained conservative by holding mainly cash and long-term
bonds. Lately we are seeing worsening inflation numbers and high oil prices --
as well as some wage inflation, which appears to be Federal Reserve Board (Fed)
Chairman Alan Greenspan's biggest worry. We feel there is still potential for
the Fed to raise short-term interest rates further and therefore, this sector
may not do well over the near term. Eventually, however, we believe the Fed will
succeed in bringing inflation back down and will be able to lower interest rates
again. But in the meantime we are remaining cautious; our sector allocation was
about a quarter of portfolio assets at the end of the period, and we may lower
that in the coming months.

The U.S. high-grade corporate bond sector was a weak performer for the markets
in general. Inflation concerns and more supply than demand caused prices of
high-grade corporate bonds to fall faster than prices of U.S. Treasuries, thus
decreasing the value (and increasing the effective yield) of existing high-grade
issues. This is also described as a spread widening, with the spread being the
difference in yield between high-grade issues and Treasuries.

For us, however, high-grade corporate bonds were a strong area during the
period. We feel this was because our research identified a number of utilities
as crossover opportunities. These are companies whose credit ratings could --
and in fact did -- improve, causing their bonds to cross over to a higher rating
and therefore appreciate in value. These utilities comprised most of our
high-grade corporate holdings, so we feel our research gave us an advantage that
helped us to outperform in a sector that performed poorly for the markets in
general.

In the U.S. high-yield corporate sector, which consists of bonds issued by
companies with lower credit ratings (junk bonds), one of the keys to success is
avoiding defaults. This is another sector where we feel our Original
Research(SM) has historically helped us steer clear of most potentially
problematic companies. The numbers appear to bear out that opinion; in 1999, we
were invested in only one of the 88 domestic companies that defaulted on
high-yield debt. We have also been careful to diversify in the high-yield area,
with no company representing more than 1% of portfolio assets.

Since about November of 1999, it has seemed to us that the market has been
expecting a recession because it has been discounting bonds in this sector in
anticipation of a possible 10% default rate, one of the highest rates we have
ever seen. We disagree with that expectation of recession; thus, we feel this
sector represents a great opportunity for our research to identify securities we
believe are selling at bargain prices and offering attractive yields. We have
therefore been gradually adding holdings in this sector, finding some of our
best values in media and telecom companies.

The international developed-country sector, in which our main focus is Europe,
has played a minimal role in the portfolio recently. We have been at our lowest
allocation ever, about 11% of assets, because European interest rates have been
increasing, and we don't envision the situation turning around in the near
future. One reason is that growth is accelerating in Europe, so there is upward
pressure on interest rates as competition for capital increases. In terms of
relative value, we feel there is currently more value in the United States.

In contrast to the developed countries, emerging market debt has been our
best-performing sector since the beginning of 1999. Again, we feel this is an
area where MFS research has yielded opportunities that the market in general may
have passed over. More than two years ago, for example, we identified Mexican
government bonds as undervalued issues in an improving country. Recently, major
rating agencies raised many of these bonds to investment grade. As with the
utility bonds mentioned earlier, the series benefited from having bought these
bonds early and having seen them appreciate in price as they crossed over to a
higher rating.

Management Review and Outlook -- continued

Emerging markets worldwide appear to be benefiting from improving fundamentals
and rating-agency upgrades. The restoration of credibility in Brazil, South
Korea, and Mexico, as well as continuing democratization in many of these
countries, leads us to believe that ongoing recoveries in Asia and Latin America
may continue to contribute to performance. Our holdings in this sector currently
comprise about 13% of the portfolio; since investments in emerging markets tend
to be very volatile, we limit this sector to a maximum of 15% of assets.

Finally, we may invest in the convertible bonds and preferred stocks sector. We
look to these securities to sometimes give an extra kick to performance.
Convertibles are bond-like instruments that also have equity characteristics;
generally, they are corporate bonds that are exchangeable for a certain number
of shares of stock at a preset price.

We tend to add to this sector when the stock market suffers a decline, often
causing convertibles to cheapen and trade more on their bond values, which are
usually lower than their stock values. We feel this may serve as a free option
if the stock price should recover and cause the value of the convertible to
appreciate.

In sum, our outlook for the fixed-income environment is that rates may continue
to rise over the near term and that we may experience continued volatility and
uncertainty as the Fed works to slow down the economy. In the longer term,
however, we feel the Fed's efforts will eventually succeed, which could bring
the competition for capital down and could bring rates down, perhaps as early as
late 2000.

Because they are currently so cheap, we feel that high-yield and emerging market
bonds issued by corporations with strong fundamentals may continue to do well,
even in the short term. The U.S. economy still appears to be strong, and we are
seeing improving fundamentals around the world. So we think the opportunity
exists for a flexible portfolio such as ours to benefit from investing in
selected areas.

Another positive factor we foresee is more demand for fixed-income products as
the U.S. population ages. At the same time the government is issuing less debt
because of its huge budget surpluses. We believe this combination of increased
demand and lower supply could potentially drive up bond prices -- another reason
we feel the long-term outlook for fixed-income investing is very good.

Zero Coupon Series, Portfolio 2000

For the six months ended June 30, 2000, the series provided a total return of
2.70%, which compares to a 2.96% return for the Treasury Bill Six Month Index.
The series performance includes the reinvestment of any distributions but does
not reflect any applicable contract or surrender charges. The portfolio consists
of discounted coupon or principal payments that are stripped from U.S. Treasury
securities in order to provide a predictable and compounded rate of return. With
no interest payments prior to maturity, these portfolios are more sensitive to
interest-rate changes than are comparable bond portfolios with similar
maturities. While there will be fluctuations within the portfolio subject to
interest-rate moves, all portfolio holdings are guaranteed by the U.S. Treasury
at maturity. (While the guarantees do not apply to the individual units of the
series, they assure a specified return to contract owners who hold their units
to the maturity of the series.) On November 15, 2000, the series will liquidate
its assets.


The opinions expressed in this report are those of the portfolio managers and
are current only through the end of the period of the report as stated on the
cover. The managers' views are subject to change at any time based on market and
other conditions, and no forecasts can be guaranteed.

It is not possible to invest directly in an index.

Except for the Zero Coupon Series, Portfolio 2000, the portfolios are actively

Notes to Performance Summary

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. 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. More recent returns may be
more or less than those shown. Past performance is no guarantee of future
results.

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)  Government guarantees apply to individual securities only and not to prices
     and yields of units in a managed portfolio. See the prospectus for details.

(2)  Lower-rated securities may provide greater returns, but they are also
     associated with greater-than-average risk. These risks may increase unit
     price volatility. 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.
     Please 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-eight separate series (the series) of
shares: Bond Series*, Capital Appreciation Series, Capital Opportunities Series,
Emerging Growth Series, Emerging Markets Equity Series*, Equity Income Series,
Global Asset Allocation Series*, Global Governments 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, Portfolio 2000*. The Global Asset Allocation Series, Global Governments
Series, Global Growth Series, Global Total Return Series, High Yield Series,
Managed Sectors Series, Strategic Income 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 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.

Certain series of the trust 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 - 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. Money market instruments are valued at
amortized cost, which the Trustees have determined in good faith approximates
market value. The trust's use of amortized cost is subject to the trust's
compliance with certain conditions as specified under Rule 2a-7 of the
Investment Company Act of 1940. 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. Short-term obligations, which mature in 60 days or less, are
valued at amortized cost, which approximates market value. Futures contracts and
options listed on commodities exchanges are reported at market value using
closing settlement prices. Over-the-counter options on securities are valued by
brokers. 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 in good faith,
at fair value, by the Trustees.

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

Foreign Currency Translation - 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.

Written Options - Certain series of the trust may write call or put options in
exchange for a premium. The premium is initially recorded as a liability which
is subsequently adjusted to the current value of the option contract. When a
written option expires, the series realizes a gain equal to the amount of the
premium received. When a written call option is exercised or closed, the premium
received is offset against the proceeds to determine the realized gain or loss.
When a written put option is exercised, the premium reduces the cost basis of
the security purchased by the series. The series, as writer of an option, may
have no control over whether the underlying securities may be sold (call) or
purchased (put) and, as a result, bears the market risk of an unfavorable change
in the price of the securities underlying the written option. In general,
written call options may serve as a partial hedge against decreases in value in
the underlying securities to the extent of the premium received. Written options
may also be used as part of an income producing strategy reflecting the view of
the series' management on the direction of interest rates.


                                                                              47

Notes to Financial Statements (Unaudited) -- continued

Futures Contracts - Certain series of the trust may enter into futures contracts
for the delayed delivery of securities or currency, or contracts based on
financial indices at a fixed price on a future date. In entering such contracts,
the series is required to deposit with the broker either in cash or securities
an amount equal to a certain percentage of the contract amount. Subsequent
payments are made or received by 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. 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. Investments 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.

Security Loans - State Street Bank and Trust Company ("State Street") and Chase
Manhattan Bank ("Chase"), as lending agents, may loan the securities of the
series to certain qualified institutions (the "Borrowers") approved by the
series. The loans are collateralized at all times by cash and/or U.S. Treasury
securities in an amount at least equal to the market value of the securities
loaned. State Street and Chase provide 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 agent. On loans
collateralized by U.S. Treasury securities, a fee is received from the Borrower,
and is allocated between the series and the lending agent. Income from
securities lending is included in interest income on the Statement 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. 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.

Notes to Financial Statements (Unaudited) -- continued

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. Certain series of the trust use
the effective interest method for reporting interest income on payment-in-kind
(PIK) bonds. Some securities may be purchased on a "when-issued" or "forward
delivery" basis, which means that the securities will be delivered to the series
at a future date, usually beyond customary settlement time.

Legal fees and other related expenses incurred to preserve and protect the value
of a security owned are added to the cost of the security; other legal fees are
expensed. Capital infusions made directly to the security issuer, which are
generally non-recurring, incurred to protect or enhance the value of high-yield
debt securities, are reported as additions to the cost basis of the security.
Costs that are incurred to negotiate the terms or conditions of capital
infusions or that are expected to result in a plan of reorganization are
reported as realized losses. Ongoing costs incurred to protect or enhance an
investment, or costs incurred to pursue other claims or legal actions, are
expensed.

Fees Paid Indirectly - The series' custody 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 total expenses on the Statement
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 trust
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, which result in temporary
over-distributions for financial statement purposes, are classified as
distributions in excess of net investment income or net realized gains.

Realized gain is reported net of any foreign capital gains tax in the Statements
of Operations.

At December 31, 1999, the following series, for federal income tax purposes, had
a capital loss carryforward which may be applied against any net taxable
realized gains of each succeeding year until the earlier of its utilization or
expiration.

(6) Line of Credit

The trust and other affiliated funds participate in a $1.1 billion unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made for temporary financing needs. Interest is
charged to each series, based on its borrowings, at a rate equal to the bank's
base rate. In addition, a commitment fee, based on the average daily unused
portion of the line of credit, is allocated among the participating funds at the
end of each quarter. The commitment fee allocated to each series for the six
months ended June 30, 2000, was as follows:

The trust had no significant borrowings during the period.

(7) Financial Instruments

Certain series of the trust trade financial instruments with off-balance-sheet
risk in the normal course of its investing activities in order to manage
exposure to market risks such as interest rates and foreign currency exchange
rates. These financial instruments include written options, forward foreign
currency exchange contracts, and 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.

(8) Restricted Securities

Each series of the trust may invest not more than a certain amount of its net
assets in securities which are subject to legal or contractual restrictions on
resale. Such restrictions range between 0% and 15% of the series' net assets.

At June 30, 2000, the High Yield Series owned the following restricted
securities, excluding securities issued under Rule 144A, constituting 0.3% of
net assets 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, in
good faith, at fair value, by the Trustees.
