Letter from the President

Dear Contract Owners,

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

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

1. Volatility can be a good thing

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

2. Invest for the long term

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

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

3. Invest regularly

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

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

4. Diversify

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

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

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

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

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

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

Respectfully,

/s/ C. James Prieur

Management Review and Outlook

Capital Opportunities Series

For the six months ended June 30, 2000, the series provided a total return of
7.98%, which compares to a return of 2.53% for the average multi-cap core
portfolio tracked by Lipper Inc., an independent firm that reports performance.
The series' return also compares to a -0.42% return over the same period for
the series' benchmark, the Standard & Poor's 500 Composite Index (the S&P 500),
a popular, unmanaged index of common stock total return performance. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

The market was extremely volatile over the period, driven mainly by
interest-rate concerns. Technology and telecommunications stocks led the market
between November and March, as interest rates climbed and investors abandoned
stocks in more economically sensitive sectors. Valuations in the technology and
telecommunications sectors reached what seemed like ridiculously high levels,
especially given that many companies showed no sign of being profitable anytime
soon. Investors finally got nervous and started selling technology and telecom
names, leading to volatility in the S&P 500 through much of the spring. This
shift caused some liquidity problems in the market -- especially among small-
and mid-cap names. As technology stocks slid, safe-haven sectors like drugs,
utilities, and food benefited. In May, we finally started seeing data that
suggested the economy was slowing. This led to speculation that the Federal
Reserve Board (the Fed) might be nearing the end of its interest rate hikes,
and investors began moving back into technology stocks.

We stuck to our disciplined investment strategy, buying stocks with strong
earnings growth that were selling at reasonable prices and selling them when we
felt they were fully valued. We tried not to get caught up in the herd instinct
known as momentum buying. Instead, we took advantage of stock price weakness to
buy names that we liked. A good example is Corning, a position we started
adding to back in January. We believe this is a company that is mostly known
for its plasticware, when in fact it's the leading manufacturer worldwide of
the fiber used in the fiber-optic networks being built for high-speed data and
Internet transmission. Its stock price bounced around a lot during the
technology debacle. But earnings accelerated during the spring, and more
investors began to understand the importance of Corning's fiber business.
Several other large investments also did quite well, including Mannesmann, a
German wireless and wireline company that was bought out at a nice premium by
Vodafone AirTouch PLC, a leading international mobile telecom provider.

During the recent volatility, we maintained a sizable stake in the
telecommunications and technology sectors but used the volatility to change our
holdings. We sold positions whose quality we were concerned about and trimmed
stocks that had held up well, including well-known names such as Oracle and
Cisco. We used the proceeds to buy stocks like Vodafone that we liked but
hadn't had big positions in because they had been too expensive. We also bought
some lesser-known names at what we thought were attractive prices. Among them
were ADC Telecommunications, a networking stock; Telesystem International
Wireless, a small Canadian cellular company with investments in Eastern Europe,
Brazil, and Asia; and Cabletron Systems, a mid-size company involved in both
networking and high-end consulting. We kept stocks like Nortel Networks -- a
Canadian leader in the optical business -- that we thought had strong earnings
growth prospects not fully reflected in their stock prices.

Our energy investments contributed to our strong performance during the period.
We had more than doubled our energy stake late last year on the expectation
that oil prices were bottoming. Our biggest increase was in the oil services
area in companies that supply services and equipment for drilling rigs and oil
wells. One of our largest investments was Baker Hughes, which was the cheapest
stock in its group last fall due mainly to management problems. The stock has
since rebounded nicely, thanks to both restructuring and the rally in oil
prices this past winter. We also added to exploration and production stocks
like Noble Drilling, as well as to natural gas pipeline stocks like Enron,
Coastal, and Dynergy -- all of which did quite well during the period.

We continued to find some good buying opportunities overseas, including Samsung
Electronics, a South Korean supplier of cellular handsets and memory chips, and
NTL, which is involved in acquiring cable firms. We also bought some
telecommunications stocks -- including Nextlink and Allegiance Telecom -- when
their stock prices nosedived this spring. In the winter, when drug stocks
tumbled on worries about changes in Medicare reimbursement policies, we added
shares of Pharmacia and Bristol-Myers Squibb. Another area in which we did some
selective buying was financial services, where we added to existing holdings
like AXA Financial. We also increased our stake in AES, a leading worldwide
independent power producer that's benefiting from the deregulation of electric
power generation. Many of these stocks have appreciated significantly since we
purchased them.

It's impossible to forecast the direction of interest rates or the market. We
could well be near the end of the Fed's increases -- which would bode well for
the market -- or we could continue to see volatility. Under either scenario,
we'll maintain our disciplined investment strategy, looking for earnings growth
at a reasonable price wherever we can find it. Our approach is to be patient and
not panic even when the market seems like a roller coaster.

Equity Income Series

For the six months ended June 30, 2000, the series provided a total return of
7.17%, which compares to a -1.91% return over the same period for the average
equity income portfolio tracked by Lipper Inc. The series' return also compares
to a -0.42% return over the same period for the series' benchmark, the S&P 500.
The series performance includes the reinvestment of any distributions but does
not reflect any applicable contract or surrender charges.

The series benefited from a broadening of the market during the latter half of
the six-month period, which followed a correction in the technology and
telecommunications stocks that had led the

market earlier in the year. Though the first quarter proved challenging for
traditional value sectors like financial services, health care, consumer
staples, and industrial goods, once investors began taking interest in areas
outside of tech and telecom in late March, the environment became much more
favorable for value investors like us.

Our continued focus on high-quality companies with reasonable valuations kept
the series well positioned to participate in the areas that recovered as the
market broadened, particularly energy, financials, utilities and
pharmaceuticals. The series was able to tap into the market recovery among
financial stocks because of a big exposure to insurance companies. Insurance
companies, along with other interest-rate-sensitive stocks, had been very hard
hit during the first quarter. One catalyst for the recovery in this area was a
bid made by ING, a Netherlands-based financial institution, for ReliaStar, one
of the series' holdings. Not only did that boost the performance of ReliaStar,
it helped drive stronger performance among several life insurance companies. A
similar recovery in commercial property and casualty insurance companies,
driven by the industry's ability to raise prices, helped the performance of the
series' holdings in the St. Paul Companies and A.J. Gallagher. Another strong
performer was Hartford Financial, a company with a foot in both the life
insurance and property and casualty businesses.

During the period, we increased our holdings in energy stocks. This allowed us
to take advantage of a rally among companies that benefited from the recovery
in oil prices, especially those with exposure to gas. The series' holdings in
Phillips, Unocal, and Devon Energy were strong performers during the second
quarter. The strength in natural gas pricing also spurred a recovery in other
energy names. One particular catalyst for this recovery was the announcement of
El Paso Energy's intentions to buy Coastal Corp -- both of which we owned. The
announcement of this deal early in the year fueled greater strength in other
natural gas- related stocks at the end of March and into the second quarter.

Our anticipation of a recovery among interest-rate-sensitive companies such as
electric utilities also proved beneficial for the series' performance. Keyspan
Corp. and Pinnacle West were among our stronger performers, boosted by the
recovery in the electric utility industry, which was part of the general
broadening of the market.

Our investments in drug stocks were also notable outperformers. The drug group
as a whole, driven down earlier in the year by political concerns and the
market's exclusive focus on technology, began to recover in late March. We
increased our biotechnology stock holdings earlier this year, taking advantage
of the recovery by tapping the strong performance of companies like Pharmacia
and Abbott Laboratories.

We continued to limit our exposure to tech and telecom stocks during the period
because we believed that these companies were extremely overvalued. This
defensive posture helped the series avoid the negative impact of the correction
in these stocks in early March. As for our outlook on technology, while there
is no doubt that technology is changing the way companies conduct business,
there is a limit to the price investors will pay for these companies' stocks.

With respect to foreign stocks, we continue to believe that it makes sense to
look for good value outside of the United States, given that the U.S. market
has been such a strong performer for so long. Currently, we have about 17% of
the series' portfolio invested outside the United States. We believe that
Europe and Japan offer attractive investment opportunities, since they are both
still early in the process of restructuring, which entails cutting costs,
raising returns, and becoming more shareholder oriented.

Looking ahead, we continue to maintain our bias toward good companies with
solid businesses, strong managements, good balance sheets, and strong cash
flows. We believe the winners in this volatile market will be those companies
offering reasonable valuations, producing real earnings, and providing yield
support.

We expect the economy to slow as a result of the Federal Reserve Board's recent
interest-rate increases, and we believe that any subsequent increases will cool
inflationary pressures. If the economy does indeed slow down, we think the
market will continue to be risky for the higher-valued, high-growth areas of
the market. For this reason, we continue to be defensive and to diversify
outside of technology.

International Growth Series

For the six months ended June 30, 2000, the series provided a total return of
1.00%, which compares to returns over the same period of -3.95% and -4.11%,
respectively, for the series' benchmarks, the Morgan Stanley Capital
International (MSCI) Europe, Australia, Far East (EAFE) Index and the Lipper
International Portfolios Index. The MSCI EAFE Index is an unmanaged, market-
capitalization-weighted total return index of developed-country global stock
markets, excluding the United States, Canada, and the South African mining
component. The Lipper indices are unmanaged, net-asset-value-weighted indices
of the largest qualifying portfolios within their respective investment
objectives, adjusted for the reinvestment of capital gain distributions and
income dividends. The series performance includes the reinvestment of any
distributions but does not reflect any applicable contract or surrender
charges.

We feel our strategy of relatively broad sector diversification was a major
factor in helping us offer competitive performance in a difficult environment.
In Asia and Europe, we witnessed the same market phenomena as in the United
States: high volatility and rotation between new-economy stocks, or companies
seen as being technology rich, and old-economy stocks, that is, companies
viewed as being technology poor and as having done business the same way for a
long time. Through February 2000, we experienced a continuation of the
late-1999 rally in new-economy stocks, or what Europeans refer to as TMT:
technology, media, and telecommunications. The rally was followed by what we
view as a natural correction in high-valuation TMT issues, with money rotating
back toward old-economy stocks.

The big drivers of the portfolio's performance early in the period were our TMT
holdings. But when we gave back a portion of our TMT gains during the market
volatility in late winter and spring, the rotation into old-economy stocks
helped some of our other sectors, such as financial services. So we feel
conditions during the period supported our long-standing belief that
diversification may serve investors well by providing competitive returns over
a variety of market cycles. We also took advantage of market volatility to buy
shares in what we believed were fundamentally sound companies with depressed
stock prices.

A factor that hurt performance, however, was the decline of the euro over the
period as the dollar strengthened. Since our results must always be converted
back into dollars, any profits we make on European equities are decreased if
the euro declines versus the dollar. Conversely, a rising euro would give an
extra boost to profits on our European holdings.


                                                                               3
<PAGE>
Management Review and Outlook -- continued

Utilities and communications has remained the largest sector in the portfolio.
This is actually a byproduct of our style of individual bottom-up stock
picking, rather than a top-down decision to overweight a particular sector.
Utilities and communications, particularly telecommunications, is simply the
area in which we have found the most companies with strong earnings growth
prospects at reasonable valuations -- as opposed to some other areas of TMT,
where we feel relative valuations are not as compelling.

Although, as we mentioned, these holdings had given up some of their gains late
in the period, we still feel very positive about them as a group. Our focus has
been largely on wireless carriers and what are called alternative carriers.
These are companies that come into a market with new technology, such as
all-fiber-optic networks, and are able to undercut the incumbents' prices.
Cable & Wireless in the United Kingdom is an example of an alternative carrier.
Major wireless carriers that we hold include NTT Mobile Communications, the
largest cellular company in Japan, KPN in the Netherlands, and Vodafone
AirTouch in the United Kingdom.

The portfolio continued to benefit from research conducted firsthand by MFS
analysts around the globe. Fast Retailing is a stock that we think exemplifies
how our bottom-up Original ResearchSM may uncover new opportunities in
difficult markets. With rising unemployment and a weak economy, we would not
generally consider Japan to be a great environment in which to invest in a
retail company. But Fast Retailing is a chain of unisex casual clothing stores
that has broken out of the traditional Japanese retail mold. By cutting out
layers of middlemen, it has been able to undercut department store prices by as
much as 50% to 60%. However, until recently, the market's perception seemed to
be that the company's stock was already fully valued.

Our retail analyst in Tokyo had been following the stock for some time when he
urged us last fall to increase our existing small position in the company. The
analyst had been visiting Fast Retailing stores and seeing lines of customers
stretching around the block. Conversations with store managers confirmed that
the company was experiencing phenomenal sales growth. Further research led us
to conclude that Fast Retailing's stock was actually underpriced relative to
future earnings, and we strongly increased our position. Subsequently, the
market appears to have arrived at a similar opinion, and our holding has
appreciated considerably.

On a cautionary note, looking to the period ahead we feel that valuations in
the markets are high, so investors should not expect overall returns to be what
they've been in the past. That said, we think the prospects for earnings growth
have actually improved over the past year for a majority of the companies in
which we're invested. Japan has moved from negative to positive earnings
growth. In much of the rest of Asia, we've seen continued and accelerating
recovery from the regional financial crisis of 1998. And in Europe, our
projections of average annual earnings growth have increased from the 8% to 10%
range a year ago to 12% to 15% for 2000, a rate we feel may be sustainable into
next year.

One factor in our positive outlook is the strong dollar. We talked about this
earlier as being, in one respect, a negative for the portfolio. But it is a
positive factor for overseas firms competing against dollar-based companies. In
the United States, for example, a strong dollar makes imported goods cheaper
and therefore more competitive. We also see the establishment of the euro zone
as a positive development. We believe it is propelling European companies into
a wider marketplace, forcing them to act more competitively and to focus more
on delivering stock performance for shareholders. Other factors contributing to
our outlook for strong global earnings growth include continued deregulation in
many foreign marketplaces and industries, as well as ongoing restructuring in
Europe and Asia -- trends that echo earlier developments in the United States
that have contributed strongly to our current economic boom.

Massachusetts Investors Growth Stock Series

For the six months ended June 30, 2000, the series provided a total return of
3.75%, which compares to a 2.98% return for the average large-cap growth
portfolio tracked by Lipper Inc. The series return also compares to a -0.42%
return over the same period for its benchmark, the S&P 500. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender changes.

During a period that included dramatic market volatility, the series
outperformed both its benchmark and a majority of its peers. We attribute that
to several factors. First, we tend to be well diversified across both companies
and sectors; we avoid taking very big positions in any individual holding. In
our experience, that mitigates some of the volatility in a down market. Second,
we cut back our technology holdings early in the first quarter of 2000 because
some of these stocks reached the price targets we had set for them and others,
we felt, had risen to overly high valuations. That helped us weather a
correction that largely affected technology stocks. Third, we used the
correction as an opportunity to add to our positions in what we view as some
very good companies at bargain prices. Cisco Systems is one example.

Over the past six months, we think the likelihood of a slowdown in corporate
earnings has risen with the Federal Reserve Board's (the Fed's) increases in
interest rates. This has led us to increase the portfolio's diversification
into sectors we believe may be less exposed to the economic cycle. Two examples
are health care and business services.

We increased our weighting in health care stocks mainly by adding
pharmaceutical holdings such as Pharmacia and Warner-Lambert. The portfolio
profited handsomely when Warner-Lambert's stock rose on the news of its pending
acquisition by Pfizer, which was completed in June, and Pfizer remains a
significant holding. Short term, we expect there will continue to be a lot of
rhetoric out of Washington regarding health care regulation, but in the long
term we don't think that will seriously impact what our research indicates are
strong earnings outlooks for our pharmaceutical holdings.

Business services companies provide services that enable larger companies to
become more efficient by downsizing and outsourcing. Two examples are Computer
Sciences, an information technology consulting firm, and Automatic Data
Processing, which we feel is the market leader in payroll processing. In
addition to their strong growth prospects, we think many business services
companies offer relatively predictable, consistent revenues, as much of their
work tends to come from long-term contracts.

We continue to have a bullish long-term outlook for the portfolio's technology
and telecommunications holdings, although in the short term we feel some of
these companies could be sensitive to an economic slowdown. A look at current
spending patterns around the world offers a reason for optimism. According to
our research, spending on information technology is increasing in every area of
the world, and spending in the United States this year is estimated to reach
nearly 5% of gross domestic product.

<PAGE>
Management Review and Outlook -- continued

By comparison, however, Europe will spend about half that figure, while Japan
and other Asian countries will spend even less. We believe that in the long
term these foreign economies will need to dramatically increase their
technology spending in order to remain competitive with the United States --
and that a significant portion of that spending may go to companies in our
portfolio that are already leaders of the communications and technology
revolution, such as Cisco, Nortel, Corning, and Intel.

In describing our overall investment style and strategy, two phrases we often
use are "sustainable competitive advantage" and "flexible and opportunistic."
What we try to find for the portfolio are good businesses selling at reasonable
valuations, and one of our definitions of a good business is one that exhibits
a sustainable competitive advantage. Often that's a large market share; we tend
to invest in businesses with very few competitors. A patented product is
another form of competitive advantage; an example would be a pharmaceutical
company with the most effective drug for a certain disease or condition. Lowest
cost may be another form of sustainable competitive advantage. Micron
Technology, which became one of our top-10 holdings during the period, offers
an example. We believe the company has become a dominant global manufacturer of
dynamic random access memory (DRAM) computer chips, which are essential
components of computer hard drives, wireless phones, and other devices.
According to our research, Micron's market share was about 8% in 1997 and is
expected to reach nearly 20% this year; globally, it is one of the two
lowest-cost producers. It is also the only DRAM manufacturer that has added
significant production capacity since 1996, by acquiring a chip factory from
Texas Instruments. Currently, demand for DRAM chips is outstripping supply; we
feel this situation could continue for some time and lead to dramatic price
increases. So we believe Micron has a sustainable competitive advantage as a
result of being one of the lowest-cost producers and having a dominant market
share of a product experiencing high demand.

Flexible and opportunistic are really two aspects of the same strategy. As
long-term investors, we try to buy stocks we believe we can hold for three
years or more. But we also recognize that the investing landscape changes daily
and has become increasingly volatile in recent years, due largely to the
instantaneous flow of large amounts of information. We try to be flexible and
take advantage of the opportunities that the market presents, in part by
purchasing stocks we believe have strong growth prospects over the long term
but are undervalued over the short term -- perhaps because of some negative
announcement or what we believe is a false rumor. Everything continues to be
driven by our Original ResearchSM; in many cases our analysts have identified
companies in which we would like to invest when a drop in their stock price
presents us with an opportunity.

New Discovery Series

For the six months ended June 30, 2000, the series provided a total return of
10.14%, which compares to a 9.45% return for the average small-cap growth
portfolio tracked by Lipper Inc. The series' return also compares to a 3.04%
return over the same period for the series' benchmark, the Russell 2000 Total
Return Index (the Russell 2000). The Russell 2000 is an unmanaged index
comprised of 2,000 of the smallest U.S.-domiciled company common stocks that
are traded on the New York Stock Exchange, the American Stock Exchange, and
NASDAQ. The series performance includes the reinvestment of any distributions
but does not reflect any applicable contract or surrender charges.

Despite a dramatic market correction this past spring, performance of the
portfolio remained strong. We feel this was in large measure due to our
consistent bottom-up focus on the fundamentals of each individual stock we
hold. And although ours is a growth portfolio, we remain constantly vigilant on
valuations (prices in relation to projected fundamentals and earnings). In late
1999 and into the first quarter of this year, we felt that even stocks of some
sound companies with high growth rates had reached valuations that
substantially exceeded what was fundamentally justified. This led us to reduce
our exposure to a number of technology issues. In March and April, when it
became clear that the Federal Reserve Board (the Fed) was intent upon slowing
the growth rate of the economy and muting the wealth effect created by a strong
stock market, many of the high valuation stocks that we had previously sold
were extremely hard hit. The portfolio's strong relative performance during
such difficult periods illustrates how a disciplined, research-driven approach
may translate into outperformance during down markets, as well as up markets.

Over the recent period, selected stocks in the energy, business services, and
health care sectors were among the portfolio's strongest performers. In the
energy sector, our research correctly anticipated last year that rising energy
prices would bring many deep-water oil drilling companies and natural gas
exploration and production companies out of their cyclical slump. During the
second half of 1999, at a time when the market was largely ignoring these
stocks, we increased our holdings in oil services firms such as Noble Drilling
and Cooper Cameron and natural gas producers such as EOG Resources. Over the
first half of 2000, the market apparently recognized the potential of these
companies, and their stocks have been strong performers for the portfolio.

Business services companies have been a significant theme in the portfolio for
some time. These are firms that design and implement computer and information
technology systems for other companies, helping their clients use technology to
increase productivity and reduce costs. One characteristic that makes business
services companies attractive is their relative predictability of earnings,
because much of their income is based on long-term contracts. Because they are
selling services more than products, they also appear to be able to ride the
technology wave with relatively less risk of a product becoming obsolete.

However, the stocks of many of these firms were beaten down throughout early
and mid-1999 due to fears about a Year 2000 (Y2K) related sales slump. We took
the view that the Y2K problem was going to be relatively short-lived and,
indeed, during late 1999 and the first half of 2000, many of these stocks came
back strongly. Among them were software firm CSG Systems, which does billing
for cable and telecommunications companies, and Diamond Technology Partners,
which helps Fortune 500 companies develop and implement Internet strategies.

In the health care sector, we view several companies in the medical services
and medical technology areas as having strong growth potential. These areas
have not been staples of many aggressive growth funds in the past year or so,
due largely to cutbacks in government reimbursement. In our view, however,
there will be tremendous opportunity in this sector as the average American
grows older and lives longer and as new technologies become available to treat
many conditions more effectively. Caremark Rx, provides an example of how we
use our MFS Original Research[RegTM] process to uncover new opportunities.

Caremark was a relatively unknown company in the pharmacy benefit management
(PBM) business. It manages drug benefits for HMOs and employers, addressing an
urgent need to contain prescription drug inflation. When we looked at the
company,


                                                                               5
<PAGE>
Management Review and Outlook -- continued

we noted that Caremark was the second largest independent player in a
fast-growing industry. Moreover, it was achieving the industry's fastest rate
of revenue growth, and it boasted the industry's highest profit margins.

Most importantly, Caremark was relatively unknown to Wall Street. New
management had recently taken charge and discontinued some unattractive legacy
businesses. Looking more closely, we discovered two important elements of value
that hadn't yet impacted the stock price. Firstly was Caremark's chronic
disease management business. This unit provides care to patients with chronic
diseases, frequently utilizing newly developed biotechnology-based drugs. The
valuations of similar public companies suggested this unit might be worth
almost Caremark's entire share price at the time of our purchase. Secondly,
Caremark's net operating loss carryforward, which had been generated by the
discontinued lines of business, could be used to shelter future taxable income.
This asset was worth another several dollars per share. Together, the value of
these assets suggested that by buying Caremark, we were getting the
fast-growing PBM business for free. We thus acquired a sizeable position in
Caremark, which has already appreciated considerably this year. We foresee
continued strong gains for Caremark in the months ahead.

Looking ahead, we remain confident that small-cap investing presents a
compelling combination. In our view, it exposes investors to many of the
highest-growth companies in the economy, yet currently offers lower average
valuations than large-cap stocks. And even if the economy weakens in response
to higher interest rates, we think small caps may continue to enjoy rapid
earnings growth. Our experience has been that in a slowing economy, earnings
growth may be a bit more resilient among small-cap growth companies because
historically they achieve much of their growth based on innovation and seem to
be less locked in to the economic cycle.

Research Growth and Income Series

For the six months ended June 30, 2000, the series provided a total return of
1.33%, which compares to a return of -1.64% for the average large-cap value
portfolio tracked by Lipper Inc. The series' return also compares to a -0.42%
return over the same period for its benchmark, the S&P 500. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

As we have anticipated for some time now, the market's extremely narrow,
momentum-driven run in technology and telecommunications stocks couldn't last
forever. As the market became increasingly concerned about the valuations of
these stocks, our underweighting in these sectors relative to the S&P 500
helped performance. More importantly, our focus on what we believe are
reasonably priced companies with reliable earnings growth, strong market
positions, innovative products, and management strategies that have adapted
their business models to the new economy has worked well in this volatile
environment. Finding companies that offer promising growth prospects at
reasonable prices is the starting point for our analysts. However, the ultimate
goal of our bottom-up fundamental research is to become acutely familiar with
the management and long-term business plans of every company we hold in the
portfolio. We think this will allow us to find great companies that will
outperform over time.

Within technology and telecommunications, we've tended to focus on the
industry's more stable, predictable growers -- names such as Intel, Cisco, EMC
Corp., Sun Microsystems, and Corning. While some people may argue that stocks
such as Intel, Cisco, and Sun are expensive, we see great opportunities in
them. Demand for their products and services has been accelerating, their
fundamental business prospects have seemed incredibly strong, and we believe
they can maintain their leadership positions in their respective businesses. We
see impressive demand for EMC's data storage systems continuing to drive strong
earnings growth and a similar situation in Corning's fiber-optics business.

We feel there are many different ways to determine a reasonable price for a
stock, but a stock is essentially worth the present value of its future
earnings. Nevertheless, a lot depends on the size of the opportunity and how
quickly we believe the company can capitalize on that growth potential. There
are many technology and telecommunications stocks, for example, with high
valuations, but from our standpoint some of these stocks are reasonably priced
because we feel the opportunities are so compelling.

We've recently increased our position in WorldCom because we think the stock is
undervalued. The company's shares have suffered due to antitrust concerns about
its acquisition of Sprint PCS and expectations of slower growth in its
long-distance business. While the Sprint deal is expected to be called off, we
see tremendous growth in the company's Internet-hosting business and strong
earnings prospects.

In the first quarter of 2000, we also took advantage of weakness in heathcare
stocks to increase our holdings in what we believe are top-notch companies with
strong track records, such as Pharmacia and Bristol-Myers Squibb. Some of these
stocks rallied in the second quarter, and we still believe they offer further
growth opportunities. Despite what we think may be a somewhat less robust
environment for consumer spending, we also like companies such as CVS and
Safeway because they're noncyclical businesses. People always need to buy
prescriptions, household products, and groceries, regardless of the economic
environment. We also happen to think these are two of the best-run companies in
their respective industries.

Looking forward, we'll continue to keep a close eye on the managements of the
companies, and we are always sensitive to risks in the portfolio. As a result,
we will pare back stocks or even eliminate them from the portfolio if they make
a big short-term move or exceed our expectations. We're far from greedy, and
our goal is to generate consistently competitive returns. We'll also sell a
stock if there's been an unanticipated disappointment or we believe its
fundamental business prospects have changed, but we try to avoid these
situations with our bottom-up research. Our value-oriented approach means that
we buy stocks at what we think are inexpensive valuations to begin with, so we
don't generally expect much risk of further price deterioration.

Research International Series

For the six months ended June 30, 2000, the series provided a total return of
1.18%, which compares to a return of -4.58% for the average international
portfolio tracked by Lipper Inc. The series' return also compares to a -3.95%
return over the same period for its benchmark, the MSCI EAFE Index. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender charges.

In the first quarter of 2000, we witnessed a continuation of a powerful but
narrow worldwide rally in technology, media, and telecommunications (TMT)
stocks. The series' significant exposure and favorable stock selection in these
sectors, especially in


6
<PAGE>
Management Review and Outlook -- continued

telecommunications and media, produced exceptional performance during this
period. However, a more challenging market environment developed in the second
quarter of 2000, as TMT stocks seemed to peak in March amid continued upward
pressure on interest rates. During April and May, we witnessed significant
declines in share prices, with TMT stocks abroad taking their cues from the
meltdown in the NASDAQ Composite Index, an unmanaged, market-weighted index of
all over-the-counter common stocks traded on the National Association of
Securities Dealers Automated Quotation System.

Despite the selloff in international equity markets during the second quarter,
the series managed to produce favorable performance compared to its benchmarks,
for a couple of reasons. First, solid stock selection benefited our total
return. While international markets experienced broad-based weakness in
technology stocks, our holdings in this sector generally held up well. Our
large exposure to semiconductor and electronics manufacturers such as Chartered
Semiconductor and Samsung continued to experience accelerating earnings growth
and provided a boost to performance.

Other factors contributing to performance were the series' broad industry and
geographical diversification, which is a byproduct of our bottom-up stock
picking style. In the financial sector, large holdings in AXA Group, Skandia,
and ING Groep benefited from the corporate restructuring and consolidation
trend that the industry has embraced. We're also bullish on the giant financial
institution, HSBC Holdings. Despite recent weakness, we believe the former
Hongkong Shanghai Bank looks inexpensive given its strong franchise and robust
earnings outlook.

Our significant exposure to Japanese stocks such as Chugai Pharmaceutical and
Fast Retailing also contributed positively to performance. We added Chugai
Pharmaceutical over six months ago because our analysts discovered that,
although Chugai's earnings growth was only average or slightly above average,
it appeared to have a hidden gem that was not yet reflected in its stock price.
GenProbe, a Chugai subsidiary in San Diego, was developing a blood-screening
technology that we believe may become a world standard for screening for AIDS
and other diseases. As the market has come to recognize the potential of
GenProbe, the price of Chugai stock has risen significantly. We believe it has
further potential as its blood-screening technology comes closer to its initial
product launch. Despite relatively weak consumer spending in Japan, Fast
Retailing, the discount-clothing retailer, performed well and has seen huge
demand for its products. Although Japan's economic environment remained
uncertain, investors have bid up the company's shares because its deep-discount
business model is viewed as counter-cyclical.

On the negative side, the series was hurt by its large holdings in Vodafone
AirTouch and KPN. We continue to believe that the growth and earnings outlooks
for these companies are very positive. In spite of our outlook, however, these
stocks were sold off along with most wireless and telephone services companies
during the period due to concerns about valuations and the potential escalating
costs of third-generation cellular licenses.

Looking forward, we think the pace and benefits of global corporate
restructuring and consolidation should accelerate over the next few months.
Increasingly, company executives overseas are placing more emphasis on getting
the stock prices of their firms higher. The increasing number of corporate
announcements from international companies detailing restructuring efforts and
mergers and acquisitions is evidence of this trend. Increased competition from
abroad has also forced industry consolidation to the forefront of corporate
boardrooms.

Other factors that we see benefiting stock prices overseas are accelerating
spending on new technology and increased interest in equities. We have found
that as companies increase spending on new technology, they generally reduce
costs and increase productivity. Just as this trend helped drive the U.S.
economy and stock market higher during the '90s, we believe it is starting to
benefit foreign corporations and international stock markets. Equity investing
is becoming more commonplace in many foreign countries. On the supply side,
we've seen an explosion of initial public offerings and new technology such as
electronic and Internet trading. This trend has spurred interest in trading,
stock market innovation, and even the creation of new stock markets, such as
the Neur market in Germany. On the demand side, we believe new tax-advantaged
retirement plans as well as investors' desire for higher potential returns
could generate increased cash flows into overseas markets.

Strategic Growth Series

For the six months ended June 30, 2000, the series provided a total return of
7.91%, which compares to a 2.98% return for the average large cap growth
portfolio tracked by Lipper Inc. The series' return also compares to a -0.42%
return over the same period for the series' benchmark, the S&P 500. The series
performance includes the reinvestment of any distributions but does not reflect
any applicable contract or surrender changes.

We believe the portfolio's favorable performance during a period that included
a sharp market correction this past spring resulted from both diversification
across many sectors and strong stock selection in each of our major sectors.
Our holdings included significant investments in the technology,
telecommunications, business services, financial services, retailing, and
health care sectors. Our overall investment strategy has remained unchanged,
despite the market's turbulence. We continue to look for the best growth
companies -- companies that we feel are either established leaders in their
markets or are poised to become leaders over the next few years. And we believe
that the best way to uncover these companies is through MFS Original
Research[RegTM].

Although this year's market turbulence has been largely focused on technology
stocks, we remain confident that technology is perhaps the strongest long-term
growth sector of the economy. In our view, we have been in the midst of a major
platform shift from the personal computer to Internet computing that began in
the late 1990s. We feel it is critical to be mindful of valuation, but we
foresee the potential for significant reward in identifying and investing in
companies that have the strategies and execution skills to leverage the growth
of the Internet. To some extent the correction in the technology sector
presents a good buying opportunity in both existing and new positions.

Despite the recent volatility, our stock picks did well on a relative basis. In
our view the issue for the stock market was not that technology trends were
weakening, but that valuations had risen to unsustainable levels. According to
our research, companies that investors perceived as well positioned to
capitalize on the Internet's growth often achieved huge market capitalizations
even though they were recently formed, had barely any revenue, and had no
earnings. Many of these stocks had phenomenal performance in the fourth quarter
of 1999 but were down drastically this year. We attribute part of the
portfolio's strong performance to our finding ways to participate in the
tremendous growth of the


                                                                               7

Management Review and Outlook -- continued

Internet without falling into the valuation trap of buying over-hyped stocks.

Our investments in areas such as e-commerce software, in stocks such as Oracle,
Rational Software, and Siebel Systems, have done well compared to the market
and are actually up for the year. Although we expect the technology sector to
remain volatile, we think there will continue to be groups of stocks that
outperform. We will look for these types of investments, and we expect
technology to remain at about 40% of assets.

Business services is another area in which our research has uncovered
attractive opportunities. Portfolio holdings in this sector include companies
offering services such as credit-card processing (First Data), payroll
processing (Automatic Data Processing), bank processing (Fiserv), and mutual
fund processing (BISYS). These companies have large client bases and high
recurring revenue, providing what we feel is significant visibility into future
growth. Despite this attractive business model, many of these stocks suffered
in the second half of 1999 because customers deferred purchases due to Year
2000 (Y2K) concerns. With Y2K now behind us, many business services companies
are seeing a material pickup in customer interest, which translates into higher
bookings. We believe revenue growth should accelerate through the rest of this
year, particularly in the second half. On a valuation basis, we feel these
stocks remain attractive relative to historical levels and to the broader
market.

Technology Series

The series commenced investment operations on June 16, 2000. In our view there
are several reasons why an investor might choose a pure technology portfolio,
but we believe the primary reason is simple: technology stocks have
historically exhibited superior earnings growth. We have solid conviction that,
over time, earnings growth is the strongest driver of stock returns. According
to our research, the technology sector has had the highest earnings growth rate
relative to any other sector in the market. When one looks at the shareholder
returns of the historically successful technology stocks, consistently high
earnings growth tends to be the driver of outperformance. The series is focused
on trying to identify and invest in high earnings growth technology companies
early in their life cycles. Fortunately, we have an abundance of investment
opportunities in technology, largely due to the emergence of the Internet and
an acceleration of technological change.

We think it's also important to recognize that the technology sector includes a
breathtaking variety of companies. Technology stocks today encompass about a
third of the S&P 500, and more than half of the Russell 1000 Growth Index. (The
Russell 1000 Growth Index is a market-weighted total return index that measures
the performance of those Russell 1000 companies with higher price-to-book
ratios and higher forecasted growth values relative to the companies in the
Russell 1000 Value Index. The Russell 1000 Index comprises the 1,000 largest
U.S. stocks in terms of market capitalization.) We foresee these percentages
continuing to grow as technology sector earnings growth outpaces other sectors.

Our approach to technology investing is simple; we analyze many industries in
the technology sector and assess fundamental prospects on a company and
industry basis. Industries that we believe have promising fundamentals include
Internet infrastructure, storage area networking, wireless communications and
equipment, and optical technologies. At the company level, we like to
categorize tech stocks into one of five categories based on where a company
stands in terms of its development and its business model. These categories are
as follows; established leaders, next generation leaders, emerging growth,
cycle plays, and special situations.

Established leaders are in the first category. These are the "gorillas" of
technology; they tend to be large-cap companies that are dominant in their
fields and have fully developed business models. Among these big companies, our
research seeks out the few we believe have excellent growth prospects, superior
managements, and proven track records. Returns from these stocks have tended to
be consistently strong and we have high confidence in their potential to
outperform over the long term.

We believe the next two categories, next generation leaders and emerging
growth, offer the greatest potential for high returns. Next-generation leaders
are companies that are not yet household names but we feel are on the cusp of
developing into clear leadership positions in rapidly growing industries. These
companies are still developing long-term business models, but our research has
given us solid confidence in their fundamentals and future profit potentials.
We believe our choices in this category are exhibiting early signs of market
leadership or the potential to dominate an emerging high-growth industry. Some
of these companies are profitable today, while others may be a few years away
from profitability.

Our third category, emerging growth firms, consists of companies in relatively
early stages of development. Many of these are newcomers to the public market
and are exhibiting rapid growth. However, their long-term positioning and
potential profitability may not yet be entirely clear, and we feel we need to
follow these companies over time to more clearly understand the investment
opportunity. These stocks entail the highest risk in the series, and we invest
selectively in this category. Most of these firms are not yet profitable, but
we have high confidence in their management teams' vision and ability to
execute.

Cycle plays, our fourth category, focuses largely on semiconductor stocks. The
semiconductor industry has historically been very cyclical. Our intent in this
category is to try to use our research to find individual companies we believe
are positioned to benefit from upswings in the cycle, invest in them early in
the cycle, and then move out of them before the cycle turns down.

Our final category is special situations. Stocks that fall into this category
are what we consider significantly undervalued technology companies suffering
from misinformation or negative sentiment. This is a challenging area to invest
in, but we tend to find a few ideas each year in which our research uncovers
high intrinsic value potential in these stocks. Fundamentals may be currently
weak, but we can easily identify catalysts that could result in improving
fundamentals or other catalysts that may unlock the hidden value in these
special situations.

In our experience, technology over the short term tends to be a
sentiment-driven sector, and many variables influence investors' overall
sentiment. At this time, we think two main variables will drive near-term
performance of the sector: fundamental trends and interest rates. Fortunately,
fundamental revenue and earnings growth trends have been excellent and we see
this trend continuing. Uncertainty about interest rates has, we believe, caused
much of the volatility in technology this year and is likely to continue until
the market has a firmer grasp on the U.S. economy and the direction of rates.

We see, however, at least two reasons for continued long-term optimism in the
sector. First, we believe the U.S. financial system is sophisticated enough to
provide us with a soft landing, in


8
<PAGE>
Management Review and Outlook -- continued

terms of slowing down our economy. Second, and perhaps more important, our
research indicates the companies we have invested in are profiting from global
technology spending, not just from the current U.S. economic boom. We believe
that, especially with Asia coming back from its problems of 1998, technology
spending in the rest of the world has the potential to offset a slowing U.S.
economy.

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) 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.

(2) 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. 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 Series, Equity Income
Series*, Global Asset Allocation Series, Global Government Series, Global
Growth Series, Global Total Return Series, Government Securities Series, High
Yield Series, International Growth Series*, International Growth and Income
Series, Managed Sectors Series, Massachusetts Investors Growth Stock Series*,
Massachusetts Investors Trust Series, Money Market Series, New Discovery
Series*, Research Series, Research Growth and Income Series*, Research
International Series*, Strategic Growth Series*, Strategic Income Series,
Technology Series*, Total Return Series, Utilities Series, and Zero Coupon
Series, 2000 Portfolio. All of these series are diversified except for the
Global Asset Allocation Series, Global Governments Series, Global Growth
Series, Global Total Return Series, High Yield Series, Managed Sectors Series,
Strategic Income Series, and Utilities Series which are non-diversified, as
that term is defined in the Investment Company Act of 1940, as amended. The
shares of each series are sold only to variable accounts established by Sun
Life Assurance Company of Canada (U.S.) and Sun Life Insurance and Annuity
Company of New York to fund benefits under variable contracts issued by such
companies.

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

(2) Significant Accounting Policies

General - The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The series
can invest in foreign securities. Investments in foreign securities are
vulnerable to the effects of changes in the relative values of the local
currency and the U.S. dollar and to the effects of changes in each country's
legal, political, and economic environment.

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

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

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

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

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

Short Sales - Certain series of the trust may enter into short sales. A short
sale transaction involves selling a security that the series does not own with
the intent of purchasing it later at a lower price. The series will realize a
gain if the security price decreases and a loss if the security price increases
between the date of the short sale and the date on which the series must
replace the borrowed security. Losses can exceed the proceeds from short sales
and can be greater than losses from the actual purchase of a security. The
amount of any gain will be decreased, and the amount of any loss increased, by
the amount of the premium, dividends, or interest the series may be required to
pay in connection with a short sale. Whenever the series engages in short
sales, its custodian segregates cash or marketable securities in an amount
that, when combined with the amount of proceeds from the short sale deposited
with the broker, at least equals the current market value of the security sold
short.

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

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

Fees Paid Indirectly - Each series' custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
series. During the period, the series' custodian fees were reduced under this
arrangement as noted below. Certain series have entered into a directed
brokerage agreement, under which the broker will credit the series a portion of
the commissions generated, to offset certain expenses of the series. During the
period, the series' custodian fees were reduced under this agreement as noted
below. These amounts are shown as a reduction of expenses on the 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. Each series
distinguishes between distributions on a tax basis and a financial reporting
basis and only distributions in excess of tax basis earnings and profits are
reported in the financial statements as distributions from paid-in capital.
Differences in the recognition or classification of income between the
financial statements and tax earnings and profits that result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or net realized gains.

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, to provide overall investment advisory and
administrative services, and general office facilities. The management fee is
computed daily and paid monthly at an annual rate based on a percentage of each
series' average daily net assets. The agreement also provides that each series
will be reimbursed for expenses in excess of the expense limitation indicated
below, based on average net assets of each series. Management fees and expense
limitations are as follows:

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 fees allocated to each series for the
six months ended June 30, 2000, were as follows:
