Q. How did the Series perform in 1998?
 
A. The Series posted a total return of (1.7)% (based on net asset value) for
the year. The Series lagged the Lipper Variable Products Small Cap Fund Aver-
age/15/ return of 1.4%. However, the Series did outpace the Russell 2000 In-
dex/23/, which returned (2.6)% over the same period.
 
Q. What factors had the greatest influence on performance over the year?
 
A. The past year was difficult for small-cap investors. Because economic trou-
bles in global markets had a negative effect on U.S. stocks, most investors
were risk averse. As a result, they favored the liquidity and perceived safety
of large-cap stocks, even though, in our opinion, small-cap stocks appeared
more attractively valued and appeared to present greater potential for earn-
ings growth and price appreciation.
 
Throughout the year, the portfolio held its value relative to the Russell 2000
Index. It weathered the July-August market correction well, and when the
market rebounded in the fall, the Series outperformed many of its peers.
 
Q. How did you manage the Series during 1998?
 
A. In managing the Series, we emphasized high quality securities with attrac-
tive valuations and consistent projected earnings growth. During the first six
months, we invested a significant portion of assets in real estate investment
trusts (REITs). While REITs provided relatively high dividend yields in the 6%
to 8% range, they still underperformed the Russell 2000 Index. Because of
their poor performance, we reduced the Series' allocation to REITs, and at the
end of the year, they comprised only about 5.5% of the Series assets. We be-
lieve the remaining REITs have the potential to produce solid gains and should
be attractive to investors because of their excellent yields and low prices.
 
During the second half of the year, we emphasized companies that had been out
of favor for a significant period. We found value in technology and health
stocks. At the end of the year, technology and health stocks accounted for
21.5% of the Series' assets. Many high quality technology companies had been
underperformers since 1996 and were selling at very low valuations. Two par-
ticularly strong performers were Alpha Industries, a semiconductor manufac-
turer and Hutchinson Technology, a company that supplies components to the
disk-drive industry. Both stocks more than doubled in price during the fourth
quarter.
 
At the end of the year, 9.1% of the assets were invested in health care
stocks. Athough these stocks got off to a slow start, by the end of the year
many of them generated double digit returns. These companies included Alle-
giance Corporation, Pathogensis and Respironics, all of which performed well
for the year.
 
Q. What is your current outlook for 1999?
 
A. Looking ahead, we believe the economic troubles in world markets may result
in a slower growing U.S. economy. We anticipate a challenging investment envi-
ronment, one in which industry groups rotate in and out of favor with invest-
ors. We feel strongly, however, that small-cap stocks offer relatively favora-
ble values. Some of the valuations of these companies are at twenty-year lows
relative to large cap stocks, and most small companies have limited exposure
to global markets. We believe these companies have the potential for strong
earnings growth and price appreciation in the months ahead.

Morgan Stanley International Magnum Equity Series
Portfolio Manager: Francine J. Bovich Morgan Stanley Asset Management

Q. How did the Series perform over the year?
 
A. The Series posted a 7.3% total return (based on net asset value) for the
year. This performance lagged the Lipper Variable Products International Funds
Average/12/ return of 13.4% over the same period. 1998 was a challenging year
for the international markets and the International Magnum Series. The Series
underperformed the Morgan Stanley Capital International Europe, AustrialAsia,
Far East Index/18/ (EAFE) which returned 20.6% primarily due to our stock se-
lection of European value stocks and small and mid-cap companies. European
value stocks have been underperforming European growth stocks by a wide margin
for the past six months, with the largest companies providing the majority of
the gains as investors sought safety in the most liquid names. On the positive
side, stock selection in Japan and Asia enhanced the Series' performance as
did our regional allocation policy, in which we were overweight or neutral in
Europe and underweight in Japan and Asia virtually all year. Stock selection
in Europe, however, was the main factor in the Series' underperformance.
 
Q. How did you manage the Series during the year?
 
A. Although the benchmark EAFE Index ended the year up 20.6%, most of the in-
dex gains were attributable to a strong performance in Europe, which comprises
over 70% of the EAFE Index. Following a first quarter rally, volatility in-
creased in markets around the world. Global markets corrected sharply in Au-
gust and September, sparked by the Russian debt default and near collapse of a
U.S. hedge fund. The markets then settled down in the final quarter of the
year, posting a recovery helped by interest rate cuts in Europe and the U.S.
The weakening of the U.S. dollar at year end also contributed to returns for
dollar-based investors. The Series' European holdings underperformed the Euro-
pean index for the second half of the year after a strong performance in the
first half. While companies like Telecom Italia, Nestle, Imperial Tobacco and
France Telecom were strong performers for the year, the Series was hurt by
holdings in oil (Premier Oil, Total) as well as by weak stock selection, espe-
cially in the U.K. The Series also suffered as large and mega cap growth
stocks were unstoppable, while 1998 was one of the worst years on record for
value investors. Furthermore, the valuation gap between small/mid sized compa-
nies and their larger peers reached the widest point in over thirteen years.
The Series has increased its exposure over the last 18 months to small/mid cap
companies with relatively lower price/earnings ratios. In the recent flight to
liquidity, however, these small/mid cap companies were shunned by investors,
often for reasons unrelated to fundamentals. This has been the principal cause
for our recent underperformance.
 
Turning to our Asian ex-Japan holdings, we maintained a defensive portfolio
during the year. Although our holdings outperformed relative to the region,
most positions were still down for the year. The Series was helped by the fact
that our Asian holdings were a small (i.e., less than 5 per cent) portion of
the Series in absolute terms, and underweighted versus the EAFE Index.
 
The only strong performer in the region was the Australian Stock Index, which
rose 6% for the year as the domestic economy exhibited strong economic funda-
mentals--low inflation, sound monetary policy, a budget surplus and a healthy
banking system. Additionally, many Australian companies were well managed with
an eye toward increasing profitability. Telstra, a telecom company, Fosters, a
beer manufacturer, and National Australia Bank were all strong performers for
the year.
 
Finally, in Japan, our strategy of focusing on blue chip exporters (e.g., Sony
and Nintendo) and avoiding banks and more domestically oriented stocks con-
tributed to relative outperformance of our Japanese stocks. Japanese equities
hit 12 year lows in 1998 as sentiment became increasingly negative on the fu-
ture of the Japanese economy. As a result, we have held a smaller position in
Japan than the EAFE index. We also actively hedged our yen exposure during the
year, which was helpful as the yen fell to 147 yen per dollar during the first
half of the year, but hurt performance as the yen strengthened during the last
quarter.
 
Q. What is your current outlook for the months ahead?
 
A. We remain cautiously optimistic about the outlook for Europe in 1999, as we
expect demand for equities to continue to rise and merger and restructuring
activity to remain brisk. However, risks include the new Euro currency, which
has shown signs of possible strengthening versus the U.S. dollar and would
hurt the exporters that have led the European recovery. Furthermore, there are
signs of a more dramatic than expected economic slowing in Europe, which could
put further pressure on already high unemployment rates. Finally, valuations
particularly in the largest companies are at very high levels, making them ex-
tremely vulnerable to earnings disappointments, should the economic backdrop
 
                                                                              9

worsen. Experience tells us that owning a portfolio of undervalued companies
(e.g. low price/cash flow) builds in a margin of safety for those periods when
markets fall on tough times. While we were disappointed by our European re-
sults in 1998, we believe that with valuation gaps so extreme and earnings ex-
pectations still very positive, our European stocks are well positioned for
the new year.
 
In Asia ex-Japan, the turnaround in several key countries in the region such
as Thailand and South Korea has contributed to increasing stability and should
benefit the region as a whole in the new year. Singapore and New Zealand
should benefit more than the more insular Asian economies or Hong Kong.
Throughout the region, restructuring should become increasingly important as
companies seek to enhance their own performance and create shareholder value.
There will be several factors to monitor throughout the region, including the
performance of the Japanese economy (as it is a major trading partner with
most Asian nations), the large supply of new offerings and capital raisings we
expect to see in Asia and growth in the developed economies that are the pri-
mary markets for Asian exports. We also remain cautious about the outlook for
China and Hong Kong. China has seen several corporate defaults in recent weeks
and the recent volatility in Latin America raises questions about the strength
of the renminbi and the sustainability of the Hong Kong/U.S. dollar peg. Up-
side surprises for the region could include successful bank recapitalization
and economic recovery in Japan and stronger than expected import demand from
the U.S. and Europe.
 
1999 should be another difficult year for Japan, with GDP growth flat to nega-
tive. Further bank failures are likely and the credit crunch should continue
as a result. While Prime Minister Obuchi has provided a platform for signifi-
cant tax cuts and economic stimulus packages to support Japan on a macro lev-
el, adjustments to over capacity and over employment and deleveraging on the
micro level will probably become the dominant themes for investors in 1999. As
Japan increasingly gravitates to "international" accounting standards, corpo-
rate sector restructuring should ensue, challenging the traditional full em-
ployment socialist system and further dampening consumer sentiment as unem-
ployment rises. Japan also remains vulnerable to any global economic slowdown
as well as a stronger yen and higher domestic interest rates. We will remain
highly selective in our stock selection, favoring PC, semiconductor, service,
pharmaceutical and select domestic sectors such as housing and housing related
securities. As we enter 1999, we are cautiously optimistic that this year the
private sector will finally foster real structural changes in areas such as
wages, employment efficiencies, and shareholder value (e.g., focus on return-
on-equity). After 10 years of economic stagnation, Japan has entered the final
phase for real change, making this an important time for long term investors
in Japanese equities. Should changes occur, we believe the markets would im-
prove correspondingly.
 
In conclusion, we believe 1999 will be an interesting year in the
international equity markets overall. We have remained close to market weight
in Europe and underweight in Japan and Asia relative to EAFE for much of the
past year. Overall, we will remain vigilant to find the best investment
opportunities to put money to work, and adjust our portfolio accordingly.

Q. How did the portfolio perform in 1998?
 
A. 1998 proved a turbulent and challenging year for investors in the U.S. stock
market. During the first half of the year, stocks that had been undeservedly
oversold in the wake of the Asian crisis rebounded nicely. Inflation remained
subdued and the Federal Reserve left interest rates unchanged. The post-Asian
crisis earnings season came and went with some predictable casualties, but most
companies got through it unscathed. Moreover, after a year where value stocks
significantly outperformed growth stocks, investors returned to the more ag-
gressive discipline. By mid-July, most major market indices were trading at
record levels.
 
Amid incidents of international economic instability and domestic political
controversy, the market sold off dramatically in August. Specifically, the Rus-
sian economy collapsed and the state of Japan's banking system worsened. Eco-
nomic activity was slowed by a credit crunch, as spreads between corporate and
Treasury bonds widened. As measured by the S&P 500 Index/25/, the historically
placid month of August proved to be the worst performing month since October of
1987. The markets recovered during September in anticipation of relief from the
Federal Reserve Board (the "Fed") yet sold off sharply toward the end of the
month following what was perceived to be a disappointing reduction of the Fed-
eral Funds Rate by 0.25%.
 
As October progressed, stocks gained a boost from a rare intra-meeting rate re-
duction by the Fed. The technology sector stabilized as Intel, Microsoft and
Apple all reported better than expected quarterly earnings. A rally prompted by
additional relief from the Fed in November highlighted a strong fourth quarter,
which anchored another lucrative albeit challenging year for the U.S. stock
market. As a result, the Alger Equity Growth Series posted a quarterly return
of 26.1% which brought its return for 1998 to 47.8% (based on net asset value),
significantly outpacing the Lipper Variable Products Growth Fund Average/10/
return of 24.7% and the S&P 500 Index/25/ which returned 28.7% for the year.
 
Q. How did you manage the Series during the past year?
 
A. The management of the Series remained unchanged, a research intensive, bot-
tom-up approach focusing on rapidly growing large cap stocks. Strong positive
cash inflows for the year helped fuel investment opportunities and precluded
the selling of core holdings in order to satisfy redemptions.
 
The Series benefited from its large cap positioning. As of December 31, 1998
the Series possessed a weighted average market cap of $85.7 billion. The Series
strong performance for the year was also augmented by the performance of tech-
nology and pharmaceutical holdings. Notable performing stocks for the year in-
cluded America Online, Microsoft, MCI Worldcom, and Cisco Systems. Key holdings
in the retail sector also boosted the Series annual performance. These compa-
nies included Home Depot, Wal-Mart and Staples, which were all up in excess of
100% for the year.
 
Q. What is your investment outlook for the months ahead?
 
A. Looking ahead, we remain cautiously optimistic, however 1999 should be a
wonderful year for the American economy and American investors in general.
While there are undoubtedly going to be problems around the world, some new and
some recycled (Japan, Brazil, Clinton), overall, we expect the stock market to
move upward.
 
It is true that valuations are high on a historical basis. However, high valua-
tions are warranted because of the extremely low levels of both inflation and
fixed-income yields. Moreover, while corporate profits growths will be subdued
this year, growth in America's more dynamic sectors, such as technology, should
be spectacular.
 
As always, we will continue to seek out and invest in companies that we feel
will grow their earnings rapidly and consistently.

Q. How did Capital Growth Series perform during 1998?
 
A. It performed very well. For the 12 months ending December 31, 1998, the Se-
ries posted a total return of 34.1% (based on net asset value)--performance
well above that of the Lipper Variable Products Growth Fund Average/10/ return
of 24.7%. The Series also outperformed the S&P 500/25/ return of 28.7%.
 
Q. What was the investment environment like in 1998?
 
A. I would describe it as excellent. The U.S. economy was strong, inflation
was low, and interest rates declined. Having said that, during the year in-
vestors periodically became concerned that problems in foreign economies would
start to hurt growth in the United States. These problems included Russia's
devaluation of its currency and default on its debt, the ongoing decline of
Asian economies, Japan's lack of aggressiveness in attempting to overcome
problems in their economy, and worries that Brazil would devalue its currency.
The U.S. economy continued to grow in spite of these obstacles.
 
In my judgment, investors overreacted to these overseas concerns. In fact, I
would argue that these problems were beneficial for the U.S. stock market be-
cause they created deflationary influences worldwide that, in turn, helped re-
duce domestic inflationary pressures. Global turmoil created an incentive
later in the year for the Federal Reserve Board to reduce short-term interest
rates three times, which helped the U.S. stock market.
 
Q. Did this backdrop lead you to alter your investment strategy?
 
A. Not at all. I kept the fund fully invested and did not alter the structure
of the portfolio, feeling that the issues overseas would not affect our
economy. I continued to look for stocks selling at reasonable valuations that
would deliver earnings growth in excess of market expectations.
 
Q. Where did you find these opportunities?
 
A. The groups of companies that were important to the Fund over the course of
the year were banks, technology, insurance and pharmaceuticals. I felt that
certain companies in these groups were undervalued relative to their growth
prospects. For example, in the bank group I invested in Chase Manhattan, a
company with superior management that gained market share in important global
businesses and earned returns that were strong enough to spur the company to
commence a share repurchase program. Technology proved to be one of the fast-
est growing segments of the economy. Insurance companies such as American Gen-
eral and AIG were undervalued relative to their growth rates. And pharmaceuti-
cal companies were strong due to new product introductions.
 
Shareholders should know that I did not focus on these groups because I was
attracted to sector-specific trends. Rather, these groups were well repre-
sented in the Fund because they, more than others, tended to include individ-
ual stocks that I picked because they offered attractive prospects.
 
Q. Which stocks helped performance, and which ones did not?
 
A. On the positive side, Nokia enjoyed significant success in its cellular
telephone and infrastructure business, which was driven by the superior fea-
tures offered by its equipment. It gained market share in a rapidly growing
market. Warner Lambert posted strong returns based on the success of its new
anti-cholesterol drug, which garnered about a 35% share of that market and
Dell Computer, the leading personal computer company in 1998, enjoyed signifi-
cant market share gains in a strong industry. Philip Morris benefited from a
positive shift in investor sentiment, as the threat of Congressional legisla-
tion faded and a settlement with several states' attorneys general was
achieved. IBM was a strong performer as investors came to appreciate the
company's balance-sheet restructuring and share-repurchase programs, and as
its underlying businesses began to grow, particularly mainframe computers and
computer outsourcing.
 
On the negative side, Mattel posted disappointing earnings because Toys R US,
a major customer, reduced inventories. Kmart also proved to be disappointing
because the company's management, contrary to expectations, was unable to show
as much improvement as had been hoped in a difficult environment for discount
retailers.
 
                                                                             23
<PAGE>
 
Q. What is your outlook for 1999?
 
A. I expect moderate economic growth and low inflation to continue in the
United States, an environment that should be favorable for stocks. I think
that continued weakness in Japan and Latin America will continue to provide an
incentive for the Federal Reserve Board to maintain low interest rates. As far
as the Series is concerned, I will continue to focus on well established com-
panies selling at reasonable prices whose future earnings I expect will favor-
ably impress investors.

Goldman Sachs Midcap Value Series
Portfolio Manager: Paul D. Farrell; Eileen A. Aptman; Matthew B. McLennon &
Karma Wilson
Goldman Sachs Asset Management
 
Q. How did the Series perform over the year?
 
A. Goldman Sachs Asset Management ("GSAM") became the subadviser to the Goldman
Sachs Midcap Value Series (the "Series"), formerly the Loomis Sayles Avanti
Growth Series, on May 1, 1998. For the twelve months ended December 31, 1998,
the Series had a return of (5.5)% (based on net asset value), compared to the
Lipper Variable Products Midcap Fund Average/14/ which returned 18.3%. The Se-
ries also lagged the Russell Midcap Index/22/ ("Russell Midcap") which returned
10.1% over the same period.
 
Q. How did you manage the Series during the year and what factors affected
performance?
 
A. Since assuming management responsibilities for the portfolio on May 1, 1998,
GSAM has employed an investment strategy that considers three investment
themes: value, momentum and low risk. Our discipline suffered in 1998's market
environment, as stocks of companies in lower capitalization ranges were
severely harmed by investor concerns surrounding global liquidity and market
volatility. Despite a rebound in the fourth quarter of 18.5%, for the year
ended 1998, the Russell Midcap Index significantly underperformed the S&P 500
Index/25/ ("S&P 500") return of 28.7%.
 
In addition to a preference for large-cap stocks capitalization bias, investors
appeared to prefer growth versus value investing. The Russell Midcap Growth In-
dex year end return of 17.9% significantly outpaced the Russell Midcap Value
Index, which appreciated only 5.1% for the same period. On a more positive
note, this environment has created an attractive valuation opportunity. Over
the last two decades, mid-cap stocks have sold at close to a 3% premium to
stocks of larger companies. Based on 1998 earnings, the Russell Midcap Index
now sells at over a 20% price to earnings discount to the S&P 500 Index. The
Russell Midcap Index is at its most attractive valuation in over 20 years, and
our portfolio is priced at an even greater discount.
 
Currently, the average stock in the Series is valued at only 12.5 times 1999
estimated earnings, and 1.7 times book value. The Russell Midcap Index is val-
ued at 18.4 times estimated 1999 earnings and 2.9 times book value, and the S&P
500 Index at 24.8 times estimated 1999 earnings and 4.9 times book value. We
believe that the Series has the potential to overcome the
near-term uncertainty that has discounted the portfolio and achieve valuation
restoration as the long-term earnings and cash flow potential of our holdings
are realized.
 
Pharmaceutical stocks held by the Series underperformed the market during the
latter part of the reporting period as there was a rotation out of this sector
and into technology. However, pharmaceuticals have exhibited strong performance
for the one-year period and we have confidence in their long-term profitability
due to several factors: 1) we believe the aging of the "baby boom" generation
will continue to increase investment opportunities in the pharmaceutical busi-
nesses; 2) more healthcare providers are emphasizing "preventive care," driving
up demand for pharmaceutical products; 3) FDA approval time has been substan-
tially shortened (cut in half); and 4) the industry also benefits from strong
unit growth, stable pricing, and expanding margins, resulting in an increase in
earnings and free cash flow.
 
On the individual stock level, several of our technology holdings have added to
the Series' recent returns. Avnet Inc. and Vishay Intertechnology benefited
from restored investor confidence for semiconductor-related business and appre-
ciated 64% and 21%, respectively.
 
Q. What is your current outlook for the months ahead?
 
A. GSAM is optimistic about the long-term value offered by mid-cap companies,
particularly those comprising the Series. The asset class reached a significant
discount during the past year relative to issuers with larger capitalizations.
We believe the discounted valuations will attract capital and drive returns to
more traditional levels, with mid-cap stocks trading at a premium to stocks of
larger companies. In all environments, we perform rigorous, first-hand research
into mid-cap stocks which trade at a discount to the market and their peers due
to obscurity or uncertainty. We aim to exploit market anomalies by investigat-
ing what is undiscovered or misunderstood by the marketplace. The recovery ex-
perienced in the fourth quarter affirms our conviction that our value-based ap-
proach should deliver strong results to the long-term investor.

Q. How did the portfolio perform during 1998?
 
A. Investors often measure performance on both an absolute and a relative ba-
sis. After several years of solid performance on both counts, the Davis Ven-
ture Value Series fired on only one cylinder in 1998, as its solid absolute
return of 14.4% (based on net asset value) was overshadowed by returns of
28.7% and 24.7% for the S&P 500 Index/25/ and the Lipper Variable Products
Growth Fund Average/10/, respectively. During the last half of the year, the
Series posted a return of 10.4% compared to a return of 9.2% for the S&P 500
and 16.2% for the Lipper Variable Products Growth Fund Average.
 
Q. How did you manage the Series during the past year?
 
A. Several factors contributed to the portfolio's disappointing results last
year, and one contributor was mistakes. Our biggest mistake involved the Se-
ries' holdings in the energy sector. The energy services companies we own are
among the best companies in that industry. However, we overestimated how much
control a well-run company can have over its own destiny in an industry with
deteriorating fundamentals. As Asian economies slowed, the demand for oil fell
far below levels that we had anticipated. Caught with excess inventory and ca-
pacity, major oil companies dramatically reduced their exploration and produc-
tion budgets and, therefore, their need for the equipment and services pro-
vided by the type of companies that we own.
 
Although many of these stocks have fallen significantly, we do not see the
outlook brightening for some time, and we have sold many of our positions at
prices well below what we paid. While we continue to own some of these compa-
nies, such as Schlumberger and Halliburton, we have not added to them even at
these low prices.
 
A second factor contributing to our disappointing relative performance was not
a mistake, but instead was a direct result of our investment philosophy. This
philosophy includes a strict price discipline that prevents us from buying
high-flying glamorous growth companies--not because we don't like the compa-
nies, but because we don't like their high valuations. In particular, we see a
speculative bubble developing in Internet stocks were valuations have inflated
to levels reminiscent of the biotech craze of the early 1990's and the emerg-
ing markets craze of the mid-1990s.
 
Unfortunately, the outstanding performance of just these kinds of glamour
stocks drove the market last year, and not owning them hurt our relative per-
formance. Nevertheless, we think that our price discipline has served us well
over the years and helped produce strong risk-adjusted returns for our invest-
ors. As we expect 1999 to be another extremely volatile year, this discipline
will remain at the heart of our investment philosophy.
 
Another aspect of our investment philosophy that contributed to our mixed
short-term results was our fundamental belief in the importance of companies
having successful international operations. Last year, companies with signifi-
cant operations outside the United States hurt the performance of the Series.
Holdings such as American Express and Hewlett-Packard were the major contribu-
tors to our relative underperformance. But the fact that 95% of the world's
population lives outside the United States should make it obvious that the
ability to operate globally is a big long-term advantage. Unlike the category
of mistakes discussed above, our belief in being global and our price disci-
pline are at the heart of our investment process.
 
Given the poor relative showing of financial stocks last year, some investors
have asked if we consider the Series' ownership of many high-quality financial
companies to be a mistake. We do not. First, we always remember that financial
stocks rarely perform in a uniform way. For example, while companies such as
BankAmerica and Allstate were down 1% and almost 14%, respectively, the shares
of SunAmerica and Progressive surged 90% and 41%, respectively. More general-
ly, however, we continue to think that favorable demographics, a benign inter-
est-rate environment, ongoing consolidation and the globalization of the fi-
nancial industry combined with reasonable valuations make this diverse sector
an attractive area to be invested in.
 
Q. What is your current outlook for the months ahead?
 
A. Looking ahead, if the market euphoria leading up to the new millennium con-
tinues, we may again lag behind funds that do not use a price discipline in
choosing their stocks. In such an environment, we would be pleased to again
achieve good absolute results even if relative results lag.

Our price discipline is an important element in controlling risk and avoiding
big losses, such as those investors experienced in 1973 and 1974 after a
similar bubble developed in growth stock valuations and was subsequently
burst. We've often said that a successful long-term investment record is built
as much by avoiding the big losses as by picking the big winners. In the
coming years, that theory may again be put to the test.
 
In addition to euphoria, the approaching millennium may begin to increase
investor anxiety regarding possible year 2000 computer problems. Such
uncertainty combined with such euphoria promises to create another year of
exceptional volatility that will again test investors' nerves. Although short-
term results may be extremely volatile, we feel confident that the Series is
positioned to weather any storm.

Q. How did the Westpeak Growth and Income Series perform during 1998?
 
A. For the 12 months ending December 31, 1998, the Series had a total return
of 24.4% (based on net asset value). The Series' results lagged the 28.7%
return of the S&P 500/25/ during the period but significantly outpaced the
16.5% return of the Lipper Variable Products Growth and Income Fund
Average/11/.
 
Q. Describe the market environment in 1998.
 
A. Extending what is by now a familiar story, 1998's market results were de-
fined by the performance of a relative handful of very large capitalization
stocks. The markets adjusted to the ongoing tumult in Asia and recorded a
fourth consecutive year of double-digit returns in the Dow Jones Industrial
Average and the S&P 500, two widely followed indicators of market activity.
Along the way, U.S. markets displayed remarkable resilience, snapping back
smartly from a sharp summer decline. The market's July plunge had its origins
in Moscow, where the Russian government failed to repay debt that it owed to
other countries; fears of parallel events in Brazil--and therefore much of
Latin America--extended the slide. Bond markets were especially affected, as a
flight from overseas markets into the reassuring quality of U.S. government
securities left other fixed-income sectors adrift in search of buyers.
 
The Federal Reserve Board took an assertive stance against the looming credit
crunch with three interest rate cuts between September and November, lowering
short-term interest rates by three-quarters of a percentage point. These steps
encouraged buyers to return to the markets for both stocks and bonds, and the
Dow Jones Industrial Average closed the year at 9181, not far from its then
record high of 9374, set on November 24, 1998.
 
Q. Given this environment, what was your investment strategy during the year?
 
A. Our portfolio-building style is based on analysis of dozens of fundamental
and technical measures that we use to identify stocks that may be candidates
for inclusion in the Series. To that quantitative information we apply our
professional judgment and the lessons of experience to make final investment
selections. Because we always keep the Series fully invested and never try to
gauge the market's next moves, the overall investment environment does not in-
fluence our positioning of the Series.
 
Over the course of the year, we gradually shifted the Series' portfolio empha-
sis from growth stocks to stocks in the S&P 500 Index with lower price-
/earnings ratios, an objective measure that permits investors to compare the
costs of stocks. We kept the Series underweighted in overvalued growth sectors
and in very expensive technology stocks; in both instances we thought pros-
pects for earnings expansion were fully reflected in market valuations. We
overweighted the Series' portfolio (relative to the S&P 500) in reasonably
priced technology and telecommunications companies. We were underweighted the
Series in drug companies, whose high valuations did not seem justified, and in
consumer staples.
 
Q. What were the principal factors affecting performance?
 
A. Our underweighted position in the largest-cap growth stocks left the Series
underrepresented in one of the year's most productive sectors. Avoiding ex-
tremely high-priced technology companies also hampered performance. Among the
sectors that helped performance were the regional Bell companies and estab-
lished technology companies with demonstrated earnings, including CISCO Sys-
tems, which manufactures products for computer networks, and Sun Microsystems,
the leading producer of networked workstations. Other selections that helped
boost performance were healthcare companies Genentech and Omnicare, as well as
IBM, United Technology and Gulfstream, a manufacturer of jet aircraft for
businesses.
 
Q. What is your current outlook for the market and the Series?
 
A. We believe that business conditions in Asia and elsewhere are stabilizing,
and that some overseas economies may already have begun to climb out of their
troughs. Without the drag of crisis-weakened export markets, growth in our
Gross Domestic Product should continue, but at a lower rate than in 1998. In-
flation represents no immediate threat, and we think there is enough momentum
in the economy to forestall any likelihood of a recession, especially given
the current climate of lower interest rates. But the Federal Reserve Board
will continue to have a huge impact on market psychology, and any rise in in-
terest rates could represent a significant risk for the market.
                                                                             41
<PAGE>
 
Therefore we believe that markets in 1999 will oscillate between optimism over
continued low rates and concern that continued growth could trigger a rate
hike on the part of the Federal Reserve Board, cutting short any earnings ex-
pansion and darkening the mood of investors. Perhaps most importantly, we ex-
pect that investors will finally put aside their obsession with the very larg-
est capitalization growth companies as valuations for these stocks become more
and more unrealistic--in our opinion there must come a point where valuations
mean something. The implication for the markets could be a greater focus on
value than in recent years, an eventuality that we believe we can address suc-
cessfully through the proprietary stock selection techniques that we have been
fine-tuning for over 25 years.

Q. How did the portfolio perform during 1998?
 
A. The Westpeak Stock Index Series returned 27.9% (based on net asset value)
for 1998. This return lagged the S&P 500/25/ return of 28.7% and the Lipper
Variable Products S&P 500 Index Fund Average/16/ which returned 28.3%. The Se-
ries remained fully participated in the 500 stocks which make up the S&P 500
Index. It is our strategy to weight the allocation of the Series virtually in
the same portion as the S&P 500 Index so as to better duplicate the perfor-
mance.
 
Q. What is your current outlook for the market and the Series?
 
A. We believe that business conditions in Asia and elsewhere are stabilizing,
and that some overseas economies may already have begun to climb out of their
troughs. Without the drag of crisis-weakened export markets, growth in our
Gross Domestic Product should continue, but at a lower rate than 1998. Infla-
tion represents no immediate threat, and we think there is enough momentum in
the economy to forestall any likelihood of a recession, especially given the
current climate of lower interest rates. But the Federal Reserve Board will
continue to have a huge impact on market psychology, and any rise in interest
rates could represent a significant risk for the market. Therefore, we believe
that markets in 1999 will oscillate between optimism over continued low rates
and concern that continued growth could trigger a rate hike on the part of the
Federal Reserve Board, cutting short any earnings expansion and darkening the
mood of investors. Perhaps most importantly, we expect that investors will fi-
nally put aside their obsession with the very largest capitalization growth
companies as valuations for these stocks become more and more unrealistic--
there must come a point where valuations mean something, in our opinion.

Q. Please tell us about the performance of Loomis Sayles Balanced Series over
the past year.
 
A. For the twelve months ended December 31, 1998, the Balanced Series had a
total return of 9.1% (based on net asset value). The Series underperformed the
Lipper Variable Products Balanced Fund Average/7/ which returned 14.9% over
the same period.
 
Q. What was the investment environment like and how did you respond during
this period?
 
A. Large capitalization growth stocks drove the popular market averages to
double digit returns again in 1998. Repeating a four year pattern, returns on
most individual stocks failed to reflect strong gains seen in the broader in-
dices. As an example of the very narrow range of stocks that defined perfor-
mance, just ten stocks out of 500--the ten largest in the S&P 500/25/--ac-
counted for nearly half of that Index's return last year. In addition, sharp
drops and recoveries were more frequent than we have seen in several years, as
the investment mood swung from near euphoria to anxious unease. Behind this
volatility was the same question that caused so much uncertainty in 1997:
Would upheavals in Asia and elsewhere take a severe toll on corporate earnings
in the United States? That concern applied not only to exporters whose sales
were directly affected by weak economies and falling currency values overseas,
but also to manufacturers and others whose pricing might be undercut by low
cost and competitive imports.
 
Soon, anxiety grew that a drop in corporate profits was imminent. In fact,
several companies alerted analysts that their optimistic earnings forecast
might need to be revised. But a decline in interest rates gave the market a
solid underpinning and investors planned on continued economic expansion.
 
Q. Given this environment, what was your equity strategy over the year?
 
A. Early in 1998 we positioned the Series to emphasize cyclical sectors, in-
cluding basic industries like chemicals and industrial companies, and consumer
cyclicals, because of the attractive valuations relative to the market. By cy-
clical companies we mean are those whose fortunes rise and fall with swings in
the nation's economy.
 
As the year evolved and the corporate earnings outlook began to deteriorate,
we cut back exposure to cyclical industries and built up the Series' holdings
in consumer staples as well as financial and energy stocks. Staple industries
supply services or products that are in relatively constant demand regardless
of economic ups and downs, such as food and health care.
 
In view of the uncertain economic climate overseas, we added positions in the
retail industries. In our view, retailers seemed well insulated from foreign
economic problems; nearly all of their revenues originate domestically. More-
over, retailing is a natural beneficiary of the nation's sustained low unem-
ployment rate and resulting high levels of consumer confidence.
 
For most of the year, the Series' asset allocation--the way it is divided be-
tween stocks and bonds--remained fairly stable at 60% stocks/40% bonds.
 
Q. What were the principal factors affecting equity performance?
 
A. It was a difficult year for our value-focused investment style. With in-
vestors focused on a few large-cap growth stocks, other sectors, including
value orientated areas where the Series concentrates, were largely neglected.
Nevertheless, the Series benefited from its commitment in the regional Bell
companies. Ameritech, Bell Atlantic, Bell South, and SBC Communications posted
impressive gains for the year. Investment by the

Series in the technology sector also produced solid gains. Individual stocks
such as IBM, Sun Microsystems and Gateway 2000, were the Series major contrib-
utors in this sector.
 
Performance suffered principally because our investment style excludes very
high-priced stocks like those that dominated the market activity this past
year. Investments in energy and oil-related sectors also were disappointing,
due in part to the falling oil prices worldwide.
 
Q. What was the environment like for the fixed-income segment of the Series
and how did you respond?
 
A. Most bond markets were extremely volatile last year, as shifting economic
news had investors rapidly shifting from one sector to another. The year began
relatively quietly, with fairly narrow differences between yields--known as
spreads--on quality corporate bonds and those on U.S. Government issues. Nar-
row spreads generally signal confidence in the outlook for corporate bonds.
But when confidence evaporated in the second and third quarters of 1998, in-
vestors sold corporates and fled to the relative safety of Treasury securi-
ties. This "flight to quality" was triggered by the default of Russia on it
sovereign debt. All debt tied to emerging markets quickly became so suspect
that there were essentially no buyers in the sector. Investors moved out of
U.S. corporate issues for fear that deflation--falling prices and sinking
profits--and possible recession would invade the U.S. economy from overseas.
 
After the Federal Reserve Board's three cuts in short-term interest rates last
Fall, investors began returning to corporate bonds; spreads again narrowed and
performance improved in many sectors. At year-end, bond markets fell back
slightly, as low unemployment and other indicators suggested that economic
growth would persist, at least for a time. Strong growth tends to raise con-
cerns over rekindled inflation, a development that could undermine the values
of fixed-income assets.
 
The bond portion of the Series benefited from our decision to avoid all emerg-
ing market debt and to concentrate on Treasury securities and high quality U.
S. corporate bonds. Early in 1998 we reduced exposure to corporate issues be-
cause they were expensive compared to Treasury securities. To add potential
impetus to our Treasury purchases, we extended duration of that part of the
portfolio. (Duration is a measure of a portfolio's sensitivity to changes in
interest rates.) By year-end we had changed emphasis, taking advantage of at-
tractive prices among quality corporate bonds. These purchases built the Se-
ries' corporate position to 60% of the fixed-income portfolio, well above the
sector's 25% representation in the Lehman Brothers Corporate Bond Index and
indicative of the positive prospects we foresee for these bonds.
 
Q. What is the current outlook for 1999?
 
A. We expect the U.S. economy to decelerate--growth will be slower than in re-
cent years. Although we do not anticipate recession, we believe that the re-
strained economic environment will make it difficult for companies to raise
prices, allowing only modest profit growth. Furthermore, the impact of uncer-
tainties abroad has yet to be fully felt here, in our opinion. As a result,
more companies may experience difficulties living up to analysts' expecta-
tions.
 
On the equity side, we believe our value style approach is appropriate to the
economic scenario that we expect for 1999. We may have seen the peak of
outperformance of growth stocks over value stocks for this market cycle, as
economics inevitably dictate more rational pricing. If we are correct, the Se-
ries is positioned to benefit from its basic orientation as investors turn
their attention to value stocks.
 
A slowing but non-recessionary economic outlook is also good for bonds. We an-
ticipate rates to will stay low--there is little need to fear rate hikes in a
decelerating economy. Currently, corporate balance sheets are generally
healthy. We believe consumer spending must slow soon, as individual expendi-
tures are too high for available income. A drop in manufacturing employment
because of price competition from Asia should be offset by an upswing in serv-
ice sector jobs, including technology, keeping unemployment low.

Back Bay Advisors Managed Series

Q. How did the Series perform during the year?
 
A. The Managed Series continued its strong relative and absolute performance
during 1998, returning 19.7% (at net asset value) versus 13.4% for the Lipper
Variable Products Flexible Portfolio Fund average/8/. The Series' performance
was basically in line with an unmanaged composite of 60% of the S&P 500 In-
dex/25/ (which returned 28.7% for 1998) and 40% of the Lehman
Government/Corporate Bond Index/3/ (which returned 9.5% for 1998) for a blended
return of 20.9%. The Series was ranked 14th of 89 funds in its peer group of
Lipper Variable Products Flexible Portfolio Funds for 1998, and is ranked 5th
for the three year period and 4th for the five year period.
 
Q. How did you manage the Series during the past year and what affected
performance?
 
A. Global financial turmoil accelerated in the third quarter (particularly in
August), taking its cue from the collapse of Russian financial markets--the
latest victim of the global liquidity/currency crisis that was first manifested
in Thailand over one year ago. Increased global market volatility and investor
uncertainty flowed over into the remaining G-7 non-Asian financial markets,
causing substantial damage to global equity and credit markets, with a corre-
sponding flight to quality (i.e. U.S. Treasuries). However, during the fourth
quarter, there was a dramatic reversal of the flight-to-quality trade of the
third quarter, as investors reduced U.S. Treasuries and other high quality safe
haven investments and began searching for reasonably valued stocks, and in a
more measured fashion, fixed income spread markets--markets that had been
shunned by investors at any cost just weeks earlier.
 
I managed the stock allocation between 63% and 68% of the total portfolio dur-
ing the 1998, and reduced the stock allocation on several occasions as equity
prices breached historically "full" valuation levels. Most recently, the stock
portion of the portfolio appreciated from 63.5% in September to 67.5% late in
December with the market rebound. However, with stock valuations at new record
highs, earnings growth uneven, the near term outlook for Treasury yields and
financial market volatility remaining stubbornly high, I shaved the stock allo-
cation back to 64.4%--just below my neutral allocation of 65/35 percent
stock/bond. Cash proceeds from the stock sale were used to modestly reduce the
duration of the bond portfolio and to add to Yankee sovereign exposure. The
bond portfolio was managed throughout the year with an overweight position to
spread product, providing the portfolio with a substantial yield advantage over
U.S. Treasuries. Credit spreads, which widened dramatically during the third
quarter on the global liquidity crisis, narrowed sharply during the fourth
quarter.
 
Q. What is your current outlook for the months ahead?
 
A. The U.S. domestic economy has proved very resilient to the tremendous finan-
cial market volatility and economic adversity that has been caused by the suc-
cession of emerging market crises over the past year and a half. Meltdowns in
Asia, Russia and now Brazil have sent liquidity-driven shock waves through
world financial markets and yet, after substantial sell-offs in risk assets
(stocks, corporate bonds, yankee bonds and mortgage pass-throughs), investors
have returned each time to buy the dip in price. While the unflappable consumer
has been instrumental in helping to sustain U.S. economic growth through this
period, the cornerstone of market confidence has rested on the Federal Reserve
Board's willingness to provide the market with much needed liquidity. This has
played a critical role in limiting the damage to financial markets, as hedge
funds, investment dealers and other financial institutions were forced to sell
losing positions and to de-leverage balance sheets during the second half of
1998. The inflation outlook remains positive at the sub-2% level and the U.S.
economy appears to be on track for another year of solid (but not runaway)
growth in the 2.5%-3.0% range. Asia also seems to be turning the corner, with
the region expected to register positive Gross Domestic Product growth in 1999,
after a significant contraction in 1998.
 
Corporate earnings growth projections have improved from expectations just last
fall, but leave little room for financial mishaps, such as the possible adverse
effect on the U.S. economy from a more protracted downturn in Latin economies
after Brazil's currency devaluation (the largest Latin
 
                                                                              67

economy and one of the U.S.'s largest trading partners). Liquidity is cur-
rently fueling the strong performance in U.S. (and global) financial markets,
with U.S. equity markets, in particular, benefiting in part from investors'
fear of missing the next rally. Bond yields are expected to remain range-
bound, helping to support high equity market multiples, with any commodity
price pressures in upcoming quarters largely mitigated by continued excess
global capacity. Therefore, over the near term, I expect that equity market
risk premiums will remain at low levels, supporting my neutral benchmark
weighting of 65 percent/35 percent stock-bonds, despite full stock valuations.
 
Clearly, the evolving corporate earnings growth/yield outlook will be critical
to maintaining the current allocation of stocks versus bonds. Whereas the
overall large-cap growth bias of the stock portfolio has driven performance
over the past several years, select large cap value holdings should start to
contribute more to the bottom line. Within the fixed income portion of the
portfolio, I expect to remain overweight to the credit sector and to maintain
a long duration, with further spread contraction from present non-recession
wide spreads expected to contribute to above average returns over the next
quarters.

Q. How did the Series perform in 1998?
 
A. The Salomon Brothers Strategic Bond Opportunities Series had a total return
of 2.0% (based on net asset value) for 1998 versus 5.1% for the Lipper Variable
Products General Bond Fund Average/9/ and 8.7% for the Lehman Brothers Aggre-
gate Bond Index/2/. Underperformance of the Series was largely due to its expo-
sure to high yield and emerging markets debt during the unexpected credit cri-
sis in the summer of 1998.
 
Q. How did you manage the Series during the year?
 
A. For bonds, 1998 was a mixture of good and bad news. The good news was that
interest rates fell approximately 1% across the yield curve. Though low infla-
tion contributed to lower bond yields, exogenous factors such as equity market
fears, default fears and expectations of spreading global economic weakness
gave investors sufficient reasons to seek only the safety and liquidity of the
Treasury sector. The bad news for bonds that were not Treasuries was that yield
spreads across all sectors widened toward unexplainable and unsustainable lev-
els. High yield bonds and emerging market debt suffered their worst perfor-
mances in years. This was largely due to the increased global spreads.
 
Early in 1998, domestic demand readings in the U.S. remained exceptionally
healthy, benefiting from low interest rates, low unemployment rates and high
consumer confidence. Lower quality high yield bonds outperformed, so the Series
reaped the profits and upgraded into relatively higher quality bonds. The Se-
ries maintained a neutral duration relative to the Lehman Brothers Aggregate
Bond Index and increased its over weighting in mortgage backed securities. The
Series continued to invest in discount coupon mortgages and seasoned pass
through mortgages because of their superior performance as interest rates de-
cline. The Series ended the first quarter with 42% U.S. Investment Grade Bonds,
32% High Yield Bonds, 15% Emerging Markets Debt, 7% Non-U.S. Government Bonds
and 4% Cash.
 
The Series maintained its weightings in the high yield sector throughout the
second quarter, as credit fundamentals remained favorable. We continued to seek
opportunities to upgrade credit quality and moved to a more defensive position
within the sector. In the emerging markets sector of the portfolio, we lowered
our exposure to Russia and added Bulgaria and Peru. Mexico and Argentina con-
tinued to be core holdings, as their fundamentals remained strong.
 
During the third quarter, heightened global market volatility caused the Series
to take a more defensive stance in its high yield sector and to lower its allo-
cation to the emerging markets debt sector. We continued to decrease the Se-
ries' exposure to Russia and increase its positions in Argentina and Mexico as
fundamentals appeared more favorable. The Series continued to favor discount
and coupon mortgage backed securities in the investment grade portion of the
portfolio. The Series ended the third quarter with 45% investment grade, 30%
high yield, 13% emerging market debt, 6% non-U.S. dollar denominated bonds and
6% cash.
 
During November, high yield and emerging debt markets snapped back strongly
when it became apparent to investors that the financial market crisis was end-
ing. Bold steps taken by the Federal Reserve Board (the "Fed") in lowering
short-term interest rates and restoring liquidity in the markets began to put
investors at ease. We maintained our high yield sector of the portfolio as
credit spreads had room to improve and interest rates were cut 0.75%. We have
increased the Series' allocations in the emerging markets debt sector from 15%
to 23%, as the markets have recovered some 20% since their lows in early Sep-
tember.
 
Q. What is your outlook for the Series in 1999?
 
A. Investor optimism and recent economic data suggest that the U.S. economy is
performing well in the new year. As booming sectors moderate and external
growth continues to fade the current expansion will slow perceptibly. The opti-
mistic view assumes that the rest of the financial world holds together. Out-
side the U.S., where the main threat to domestic stability first emerged, con-
ditions have deteriorated since the Fed last rate cut. This backdrop leaves the
Fed in a watchful state, despite the complacency of today's marketplace and
 
                                                                              75

strong fourth-quarter Gross Domestic Product growth. Near-term job and eco-
nomic growth probably will remain fairly buoyant, given the boost from lower
commodity prices, warm weather and the fresh rise in the equity market. Howev-
er, with inflation pressures in remission, the Fed will have ample leeway to
renew its rescue efforts in 1999 if necessary.
 
We remain optimistic about the high yield market, as interest rates are low
and credit spreads have room to improve. The emerging debt markets have recov-
ered by some 20% since their lows in early September and while there will be
bumps along the way, we expect emerging debt to outperform the U.S. investment
grade market in 1999. We have increased our allocations in that sector from
15% to 23%.

Q. Please tell us about Bond Income Series' performance during 1998.
 
A. We're proud of the Series performance. The Series continued its record of
providing consistently solid returns despite investment conditions that fa-
vored the safest financial instruments--U.S. Treasuries--instead of corporate
bonds, the Series chief investment. The Series ended the year with a total re-
turn of 9.0% (based on net asset value). This compares favorably to the Lipper
Variable Products "A"-Rated Corporate Bond Fund Average/6/ return of 8.1%, and
the Lehman Intermediate Government/Corporate/5/ composite return of 8.4%.
 
Q. What was the investment environment throughout the past year?
 
A. Positive economic expectations and the accompanying fear of renewed infla-
tion brought lower bond prices early in the year. The belief that Asia's eco-
nomic turmoil was largely spent suggested better business conditions for U.S.
exporters and possible upward pressure on prices, a combination that could
prompt the Federal Reserve Board to raise interest rates--usually a negative
for bonds. (Generally, bond prices and interest rates move in opposite direc-
tions.) Later, it became clear that Asia's financial crisis was unlikely to
end soon, removing a possible stimulus for U.S. business conditions; bond
prices rose and yields fell. But bond buyers' confidence vanished abruptly
when Russia stunned the investment world by failing to repay debt that had
come due to several foreign governments--the bottom dropped out of most fixed-
income markets during the third quarter.
 
By August, market liquidity--the willingness of buyers to purchase bonds that
were offered for sale--had dried up across nearly the entire quality spectrum.
Concern was widespread that other countries, including Brazil, a linchpin to
all South American economies, might follow Russia's lead and fail to make good
on their sovereign obligations (government bonds). Worried investors shunned
all but the most-respected securities--those of the U.S. government. The
flight to quality left other bond market segments adrift, all but closed off
the ability of companies to raise needed cash through the issuance of new
bonds and sent the high yield bond market into a tailspin. Adding to investor
anxiety, the well publicized troubles of some large hedge funds raised fears
of further deterioration in the credit markets. In fact, in August, corporate
bonds generally experienced their worst one-month performance ever in a non-
recessionary period. Spreads between government and corporate issues--that is,
the difference in their yields--reached levels previously seen only during re-
cessions.
 
When a one quarter percentage point cut in interest rates by the Federal Re-
serve Board failed to bolster market psychology, a second, similar, cut
quickly followed, producing the desired impact. The Federal Reserve Board then
cut rates a third time, signaling to investors that it was determined not to
allow the U.S. economy to slide into an Asia-driven recession.
 
Investors returned to the better quality corporate sectors, restoring some
sense of balance and liquidity to the bond markets. During the last part of
1998, rates moved back up modestly, as continued low unemployment and other
economic indicators showed a still-expanding U.S. economy.
 
Q. Given this environment, what was your investment strategy during 1998?
 
A. In the first half of the year, we reduced exposure to high yield, lower-
grade issues and to securities that might be tainted by global turmoil. We
eliminated emerging market debt as well as obligations tied to Asian economies
with dubious recovery prospects, and added positions in the domestic utili-
ties--especially telecommunications and electric companies--whose fortunes are
not tightly tied to economic cycles. For similar reasons we increased holdings
in cable and media issues. Finally, taking a longer term view, we backed off
slowly on U.S. government holdings because of their low yields--even those
(from a short-term perspective) that tend to be issues that hold their value
best in an unsettled environment.
 
Throughout this volatile period in the fixed income market, there was a steady
flow of new money into the Series. We used this cash to add to existing posi-
tions in our favored sectors-- utilities, telecommunications and cable/media
companies-- where prices had been dragged down by market forces unrelated to
business fundamentals of individual securities.
 
At year-end we held some bonds that were below investment grade--rated below
Baa/BBB by Moody's or Standard & Poor's. In this category, we limit our com-
mitment to issues with the potential for ratings upgrades; if our analysis is
correct and upgrades result, these bonds could experience sharp rises in
price.
 
 
                                                                             85

Q. What were the principal factors affecting performance?
 
A. The Series benefited from the decision to increase holding in utilities and
cable/media industries, as those positions recovered smartly from their lows
earlier in the year. Our commitment to Canadian issues hurt results, however,
because of weakness in the Canadian dollar, which fell victim to depressed
world commodity prices. Among individual issues, the bonds of Telecommunica-
tions, Inc. and of Time Warner rose when they were upgraded by the major rat-
ings services. Holdings in Newscorp., the giant Australian media conglomerate,
fell but we remained invested. By the end of the year, this holding had recov-
ered some of its decline.
 
Q. What is your current outlook for the bond market and the Series?
 
A. As 1999 opens, we do not expect a recession in the American economy. Gross
Domestic Product should grow modestly this year, perhaps in the range of 1.5%,
a slower rate of expansion than last year. We are generally optimistic about
interest rates; the slower economic growth we anticipate should give the Fed-
eral Reserve Board no cause to raise short-term interest rates. Long-term
rates, as measured by the 30-year Treasury bond should remain fairly stable be-
tween 4 3/4 and 5 1/4%. The possibility of meaningful reforms in Brazil and
other troubled overseas economies could also ease investor concerns.
 
In late 1998, there were signs of inventory build-up in many sectors of the
economy, suggesting a manufacturing slowdown in the first half of the year and
accounting in part for our slow-growth forecast. A small acceleration in GDP
growth is possible later in the year, as companies rebuild depleted stock piles
of goods.
 
We continue to be cautious about bond markets because there are still many
imponderables overseas. The Series' duration--its sensitivity to interest rate
changes--was at around six years at the end of 1998, equivalent to an average
maturity of just under ten years. This bullish positioning reflects our view
that interest rates will be confined to a narrow range for some time. As we be-
gin 1999, we will continue to allocate the Series' cash inflows to existing
holdings and sectors as opportunities pre-sent themselves. Our emphasis will
remain on better quality U.S. corporate debt, which we believe offers the best
combination of yield and price performance for the Series shareholders.

Q. How did the Series perform in 1998?
 
A. The Salomon Brothers U.S. Government Series returned 7.5% (based on net as-
set value) for 1998, outperforming in its Lipper Variable Products U.S. Mort-
gage and GNMA Fund Average/17/, which returned 7.3% for 1998. However, the Se-
ries lagged the broader Lehman Brothers Intermediate U.S. Government Index/9/
which returned 8.5% over the year. The Series' performance resulted from its
shift into longer duration bonds and a sizable allocation to Treasuries.
 
Q. How did you manage the Series during the year?
 
A. In January, we believed that Asia's economic woes would slow economic growth
in the U.S and push inflation lower. This would enable interest rates, in par-
ticular long term rates, to move modestly lower, pushing bond prices higher. To
take advantage of our expectations for lower interest rates and a flatter yield
curve, we moved the Series at year-end 1997 into a slightly long duration
barbelled position while overweighting discount mortgage securities.
 
We held this position until mid-August when it became apparent that the global
economy would slow down more than thought previously and the Federal Reserve
Board would ease monetary policy. We strategically reduced the Series' barbell
position by swapping long maturity Treasuries and mortgages into 5-year Trea-
suries. The 5-year area of the Treasury curve often performs best just prior to
a Federal easing cycle, and this time was no exception. To maintain duration,
we sold mortgage securities trading above par and bought discount pass-
throughs.
 
During the fourth quarter, it became apparent to investors that the global mar-
ket crisis that began mid-1997 had stabilized. A 0.75% cut of the Federal Re-
serve Board Funds Rate restored investor confidence and liquidity in the mar-
kets. The main strategy change in the Series was a reallocation to mortgage
pass-throughs from Treasuries. Presently, 69% of the portfolio consists of
mortgages, up 14% from the end of the third quarter.
 
Q. What is your outlook for the Series in 1999?
 
A. After seven years of uninterrupted growth, the U.S. economy faces a period
of slowing expansion and threatened instability. Although key areas of economic
activity remain buoyant, gradual slowing remains a likely scenario for 1999.
The Federal Reserve Board will probably condition further easing on renewed in-
tensification of financial stress or evidence that demand pressures are reced-
ing.
 
We expect interest rates to generally move lower in the first few months of the
year, followed by a gradual rise through the end of 1999. With the expectation
of further Federal Reserve Board easing, we look for the yield curve to steep-
en. As such, long-term bonds may stabilize in a range centered on 5% as long-
term inflation expectations fall.

Back Bay Advisors Money Market Series
Portfolio Manager: John Maloney Back Bay Advisors, L.P.

Q. How did the Series perform over the past year?
 
A. The Series produced a total return of 5.3% (based on net asset value) for
the twelve months ending December 31, 1998 and maintained a constant $100.00*
share price. The Series' return included the reinvestment of $5.13 per share
in income distributions. As of December 31, 1998, Series' seven-day yield was
5.15%.
 
Q. What was the Fund's investment environment like during the period?
 
A. The investment environment was excellent for money market investors. In-
vestors benefited from ideal economic conditions, a favorable interest rate
environment and strong demand for safe, liquid investments. During the period,
investor concerns about global economies and the stability of the world's fi-
nancial markets caused a "flight-to-quality" that drove U.S. interest rates to
historic lows. Demand escalated only for those securities considered to have
the highest degree of safety and liquidity, typically U.S. Treasuries. To en-
courage economic growth, the Federal Reserve Board cut the Federal Funds rate
three times in the fall of 1998--from 5 1/2% to 4 3/4%. The federal funds rate
is the rate at which banks lend to each other overnight and is the benchmark
for other short-term interest rates.
 
With this background, money market investments generated solid returns that
were particularly attractive in light of their price stability. On average,
money market funds returned about 50% of the average total return of all long-
term bond funds and about 75% of the average total return of all intermediate-
term bond funds followed by Lipper, Inc. in 1998.
 
Q. What strategies did you use in managing the Fund?
 
A. We invested in securities with longer maturities in the early part of the
period because they offered an attractive yield advantage over securities with
shorter maturities. Throughout the entire period, we maintained a fairly long
average maturity --60-75 days--, which enhanced the Series' return as interest
rates fell. As of December 31, 1998, the Fund's average maturity was 58 days.
 
Q. What is your outlook for short-term interest rates over the next six
months?
 
A. We think short-term interest rates could move somewhat lower--perhaps an-
other one-quarter of one percent cut in the federal funds rate. We anticipate
slower U.S. economic growth in 1999, with a slowdown in manufacturing and a
reduction in consumer spending. However, much will depend on developments in
the global situation and the direction of the stock market.
 
The events of 1998 have underscored the value of money market holdings, which
seek capital preservation and reliable income. In our opinion, a well-rounded
investor portfolio is completed by the safety and liquidity of a money market
investment.

New England Zenith Fund
 
Notes to Financial Statements--December 31, 1998
 
1. New England Zenith Fund (the "Fund") is organized as a Massachusetts
business trust under the laws of the Commonwealth of Massachusetts pursuant to
an Agreement and Declaration of Trust dated December 16, 1986 as amended. The
Fund succeeded to the operations of The New England Zenith Fund, Inc. on
February 27, 1987. The Fund is registered under the Investment Company Act of
1940, as amended ("the 1940 Act"), as a diversified, open-end management
investment company.
 
Shares in the Fund are not offered directly to the general public and are
currently available only to separate accounts established by Metropolitan Life
Insurance Company ("MetLife") and New England Life Insurance Company
("NELICO"), an indirect subsidiary of MetLife, as an investment vehicle for
variable life insurance or variable annuity products, although not all Series
are available to all such separate accounts.
 
The Fund's Agreement and Declaration of Trust permits the issuance of an
unlimited number of shares of beneficial interest, no par value, in separate
series (each a "Series"), with shares of each Series representing interests in
a separate portfolio of assets.
 
The following is a summary of significant accounting policies followed by the
Fund in the preparation of the Financial Statements of each Series. The
policies are in conformity with generally accepted accounting principles for
investment companies. The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures in
the financial statements. Actual results could differ from those estimates.
 
A.Security valuation
 
  As permitted under Rule 2a-7 of the 1940 Act, and certain conditions
  therein, the Back Bay Advisors Money Market Series employs the amortized
  cost method of security valuation which, the Fund's Board of Trustees (the
  "Board") has determined, approximates the fair market net asset value per
  share of the Series. The Board monitors the deviations between the Series'
  net asset value per share, as determined by using available market
  quotations, and its amortized cost price per share. If the deviation
  exceeds 1/2 of 1%, the Board will consider what action, if any, should be
  initiated.
 
  Debt securities (other than short term obligations with a remaining
  maturity of sixty days or less) are valued on the basis of valuations
  furnished by independent pricing services authorized by the Board. Short
  term obligations with a remaining maturity of sixty days or less are stated
  at amortized cost value which approximates fair market value. Equity
  securities are valued using the last reported sale price for securities
  listed on that security's principle trading exchange or on the NASDAQ
  National Market System (if that is the security's principle trading
  market), or, if no sale was reported and in the case of over-the-counter
  securities not so listed, the last reported bid price by a broker making a
  market in such security. Securities and assets for which market quotations
  are not available are valued at their fair value as determined in good
  faith by the Fund's advisers and subadvisers, under the supervision of the
  Board.
 
  Securities traded primarily on an exchange outside of the United States
  which closes before the close of the New York Stock Exchange generally will
  be valued at the last sales price on that non-U.S. exchange, except when an
  occurrence after closing of that exchange is likely to have materially
  changed such security's value as determined by a Series' subadviser under
  the direction of the adviser.
 
B.  Foreign currency translation--The books and records of the Fund are
    maintained in U.S. dollars. The values of securities, currencies and other
    assets and liabilities denominated in currencies other than U.S. dollars
    are translated into U.S. dollars based upon foreign exchange rates
    prevailing at the end of the period. Purchases and sales of investment
    securities, income and expenses are translated on the respective dates of
    such transactions. Since the values of investment securities are presented
    at the foreign exchange rates prevailing at the end of the period, it is
    not practical to isolate that portion of the results of operations arising
    from changes in exchange rates from that portion of
 
                                                                            105

New England Zenith Fund
 
Notes to Financial Statements--December 31, 1998--(Continued)
 
   the results of operations reflecting fluctuations arising from changes in
   market prices of the investment securities. Such fluctuations are included
   with the net realized and unrealized gain or loss on investments.
 
  Net realized foreign exchange gains or losses arise from sales of foreign
  currency, currency gains or losses realized between the trade and
  settlement dates on securities transactions, and the difference between the
  amounts of dividends, interest, and foreign withholding taxes recorded by
  each Series and the U.S. dollar equivalent of the amounts actually received
  or paid by each Series. Net unrealized foreign exchange gains and losses
  arise from changes in the value of assets and liabilities, other than
  investment securities, resulting from changes in the exchange rate.
 
  Forward Foreign Currency Contracts--Certain Series may use foreign currency
  contracts to facilitate transactions in foreign securities and to manage
  the Series' currency exposure. Contracts to buy generally are used to
  acquire exposure to foreign currencies, while contracts to sell are used to
  hedge the Series' investments against currency fluctuations. Also, a
  contract to buy or sell can offset a previous contract. These contracts
  involve market risk in excess of the unrealized gain or loss reflected in
  the Series' Statements of Assets and Liabilities. The U.S. dollar value of
  the currencies the Series has committed to buy or sell is shown in the
  Schedules of Investments under the caption "Forward Contracts Outstanding."
  This amount represents the aggregate exposure to each currency the Series
  has acquired or hedged through currency contracts at period end. Losses may
  arise from changes in the value of the foreign currency or if the
  counterparties do not perform under the contract's terms. The U.S. dollar
  value of forward foreign currency contracts is determined using forward
  currency exchange rates supplied by a quotation service.
 
  All contracts are "marked-to-market" daily at the applicable translation
  rates, and any gains or losses are recorded for financial statement
  purposes as unrealized until settlement 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.
 
C.  Security transactions and related investment income--Security transactions
    are accounted for on the trade date (date the order to buy or sell is
    executed). Dividend income is recorded on the ex-dividend date and
    interest income is recorded on the accrual basis. In determining gain or
    loss on securities sold, the cost of securities has been determined on the
    identified cost basis.
 
D.  Futures contracts--The Westpeak Growth and Income, Goldman Sachs Midcap
    Value, Westpeak Stock Index, Back Bay Advisors Managed, Loomis Sayles
    Balanced, Morgan Stanley International Magnum Equity, Salomon Brothers
    U.S. Government, Salomon Brothers Strategic Bond Opportunities and Davis
    Venture Value Series each may enter into futures contracts (or options
    thereon) on the S&P 500 Index or other indices of stocks or on interest-
    bearing securities or indices thereof, to hedge against changes in the
    values of securities the Series owns or expects to purchase or, in the
    case of Goldman Sachs Midcap Value Series, to increase total return.
    Futures contracts are valued at the most recent settlement price, unless
    such price does not reflect the fair market value of the contract, in
    which case the position will be valued by or under the supervision of the
    Board. Certain risks are associated with investments in futures contracts,
    including risk of imperfect correlation between the value of a position in
    futures contracts and the value of the corresponding stocks or bonds that
    the Series is attempting to hedge. In addition, there is a risk that the
    Series may not be able to close out its futures positions due to an
    illiquid secondary market. At December 31, 1998 there were no such
    contracts outstanding.
 
E.  Repurchase agreements--Each Series, through the custodian or subcustodian,
    receives delivery of the underlying securities collateralizing repurchase
    agreements. It is the Fund's policy that the market value of the
    collateral be at least equal to 100% of the repurchase price in the case
    of a repurchase agreement of one day duration and 102% on all other
    repurchase agreements. Each Series' adviser or subadviser is responsible
    for determining that the value of the collateral is at all times at least
    equal to the repurchase price. In connection with transactions in
    repurchase agreements, if the seller defaults and the value of the
    collateral declines or if the seller enters an insolvency proceeding,
    realization of the collateral by the Series may be delayed or limited.

  The Goldman Sachs Midcap Value Series, together with other registered
  investment companies having advisory agreements with Goldman Sachs Asset
  Management or its affiliates, transfers uninvested cash into joint
  accounts, the daily aggregate balance of which is invested in one or more
  repurchase agreements. At December 31, 1998, the Goldman Sachs Midcap Value
  Series had undivided interests in the repurchase agreements in the
  following joint account which equaled $13,400,000, in principal amount. At
  December 31, 1998 the following repurchase agreements held in this joint
  account were fully collaterized by Federal Agency obligations.

</TABLE>
 
F. Short Sales Against the Box--The Alger Equity Growth, Morgan Stanley
   International Magnum Equity and Goldman Sachs Midcap Value Series may hedge
   against changes in the value of investments by engaging in short sales
   against the box. The Series had no such transactions during the year ended
   December 31, 1998.
 
G. Reverse Repurchase Agreements--The Salomon Brothers U.S. Government and
   Salomon Brothers Strategic Bond Opportunities Series may enter into reverse
   repurchase agreements with qualified, third party broker-dealers as
   determined by and under the direction of the Board. At the time a Series
   enters into a reverse repurchase agreement, it will establish and maintain
   a segregated account at the custodian or a subcustodian, the value of which
   at least equals the principal amount of the reverse repurchase transactions
   including accrued interest. The amount of reverse repurchase agreements
   outstanding at December 31, 1998 was $2,022,500, which was 4.42% of total
   assets, for the Salomon Brothers U.S. Government Series. At December 31,
   1998, there were no open reverse repurchase agreements for the Salomon
   Brothers Strategic Bond Opportunities Series.
 
H. Federal taxes--Each Series, which is a separate taxable entity, intends to
   meet the requirements of the Internal Revenue Code applicable to regulated
   investment companies and to distribute to its shareholders all of its
   taxable income and any net realized capital gains at least annually.
   Accordingly, no provision for federal income tax has been made.
 
I. Dividends and distributions to shareholders--Back Bay Advisors Money Market
   Series dividends are declared daily to shareholders of record at the time
   and are paid monthly. Dividends and distributions are recorded by all other
   Series on the ex-dividend date. Net realized gains from security
   transactions are distributed at least annually to shareholders. The timing
   and characterization of certain income and capital gains distributions are
   determined in accordance with federal tax regulations which may differ from
   generally accepted accounting principles. Permanent book and tax basis
   differences relating to shareholder distributions will result in
   reclassification to paid in capital. These differences primarily relate to
   tax equalization, investments in mortgage backed securities and investments
   in foreign securities.
 
                                                                            107

2. At December 31, 1998, MetLife held 30,906,686 shares of the Fund in
separate accounts funding annuity contracts issued by MetLife. NELICO held the
remaining 49,407,695 shares of the Fund then outstanding in separate accounts
funding variable life insurance and variable annuity contracts issued by
NELICO.
 
As long as MetLife owns (directly or through NELICO) more than 25% of the
Fund's outstanding shares, it will be presumed to be in control (as that term
is defined in the 1940 Act) of the Fund.
 
3. For the year ended December 31, 1998, purchases and sales of securities
(excluding short-term investments) for each of the Series were as follows:

(a)  Effective May 1, 1998 the Loomis Sayles Avanti Growth Series was renamed
     Goldman Sachs Midcap Value Series and a new advisory agreement between
     the Fund and TNE Advisers went into effect. The fees paid to TNE Advisers

  The Capital Growth Series pays its adviser, CGM, an advisory fee at an
annual rate of 0.70% of the first $200 million of average daily net assets,
0.65% of the next $300 million of such assets, 0.60% of the next $1.5 billion
of such assets and 0.55% of such assets in excess of $2 billion. For advisory

Bond Opportunities and Salomon Brothers U.S. Government Series. TNE Advisers,
which acts as adviser to each Series except the Capital Growth Series, is an
indirect wholly owned subsidiary of NELICO, a direct wholly owned subsidiary
of MetLife, a mutual life insurance company. Loomis Sayles, Westpeak and Back
Bay Advisors are each independently operated subsidiaries, and CGM is an
independently operated affiliate, of Nvest, L.P. and Nvest Companies, L.P.
("Nvest Companies"). Nvest Companies owns the entire limited partnership
interest in each of Loomis Sayles, Westpeak and Back Bay Advisors. The general
partners of each of Loomis Sayles, Westpeak and Back Bay Advisors are special
purpose corporations which are indirect wholly-owned subsidiaries of Nvest
Companies. Nvest Companies' managing general partner and Nvest, L.P.'s general
partner, Nvest Corporation, is an indirect wholly-owned subsidiary of MetLife
New England Holdings, Inc. which in turn is a wholly owned subsidiary of
MetLife. MetLife owns directly 46% (and in the aggregate, directly and
indirectly, 47%) of the limited partnership interests in Nvest Companies.
Nvest Companies' advising general partner, Nvest, L.P., is a publicly traded
company listed on the New York Stock Exchange. Nvest Companies is the owner of
a majority limited partnership interest in the Capital Growth Series'
investment adviser, CGM. Consequently, the subadvisers (Loomis Sayles,
Westpeak and Back Bay Advisors) of seven Series of the Fund are currently
wholly-owned subsidiaries of Nvest Companies and an additional Series is
advised by a majority-owned subsidiary (CGM) of Nvest Companies. The sub-
advisers of the remaining six Series are not affiliated with MetLife, Nvest,
L.P. or Nvest Companies. TNE Advisers paid each sub-adviser as shown below for
providing sub-advisory services to the Series:

(a)  Effective May 1, 1998 a new Sub-advisory agreement between TNE Advisers
     and GSAM went into effect, replacing the prior Sub-advisory agreement
     between TNE Advisers and Loomis Sayles. The two Sub-advisory fee
     schedules set forth above reflect all agreements which were in place
     during the year ended December 31, 1998.
(b) Effective December 1, 1998, Morgan Stanley Asset Management Inc. changed
    its name to Morgan Stanley Dean Witter Investment Management Inc. but
    continues to do business in certain instances (including as subadviser to
    the Morgan Stanley International Magnum Equity Series) using the name
    Morgan Stanley Asset Management.
 
  Voluntary Expense Limitation and Expense Deferral Agreement. Each Series,
except the Capital Growth Series, is subject to one of two forms of expense
limit. The first form of expense limit is a Voluntary Expense Limitation,
which relates to the Loomis Sayles Small Cap Series, Westpeak Growth and
Income Series, Westpeak Stock Index Series, Back Bay Advisors Managed Series,
Back Bay Advisors Bond Income Series and Back Bay Advisors Money Market
Series. A Voluntary Expense Limitation applicable to the Loomis Sayles Avanti
Growth Series terminated on April 30, 1998, the last day before the Series was
renamed the Goldman Sachs Midcap Value Series. Pursuant to this arrangement
TNE Advisers bears all expenses (other than advisory fees and any brokerage
costs, interest, taxes or extraordinary expenses) of each Series (except
 
110

New England Zenith Fund
 
Notes to Financial Statements--December 31, 1998--(Continued)
 
the Loomis Sayles Small Cap Series) in excess of 0.15% of average daily net
assets. In the case of the Loomis Sayles Small Cap Series, TNE Advisers bears
all expenses (other than any brokerage costs, interest, taxes or extraordinary
expenses) in excess of 1.00% of the Series' average daily net assets. A
similar Voluntary Expense Limitation with New England Mutual Life Insurance
Company ("The New England") was in effect with respect to the Capital Growth
Series from November 1, 1994 to April 30, 1996.
 
The second form of expense limit is an Expense Deferral Agreement, which has
been in effect since November 1, 1994 with respect to the Morgan Stanley
International Magnum Equity Series, Alger Equity Growth Series, Davis Venture
Value Series, Loomis Sayles Balanced Series, Salomon Brothers Strategic Bond
Opportunities Series and Salomon Brothers U.S. Government Series, and since
May 1, 1998 for the Goldman Sachs Midcap Value Series. Under this Agreement,
TNE Advisers has agreed to pay expenses of each Series' operations (exclusive
of any brokerage costs, interest, taxes or extraordinary expenses) in excess
of the annual percentages of each Series' net assets set forth below, subject
to the obligation of each Series to repay TNE Advisers such expenses in future
years, if any, when the Series' expenses fall below that percentage; however,
no Series is obligated to repay any expenses paid by TNE Advisers more than
two years after the end of the fiscal year in which such expenses were
incurred. The percentage applicable to each Series is shown below:
 
TNE Advisers may terminate these expense arrangements at any time. If these
expense arrangements were terminated, some of the Series would have higher
expense ratios. For the year ended December 31, 1998, (i) the maximum expense
ratio for each Series after giving effect to the foregoing arrangements; (ii)
the amounts of expenses assumed by TNE Advisers for each Series to which the
Voluntary Expense Limitation applies; and (iii) the amounts of expenses
deferred for each Series to which the Expense Deferral Agreement applies, are
as follows:

New England Zenith Fund
 
Report of Independent Auditors
 
To the Shareholders and Board of Trustees of New England Zenith Fund:
 
We have audited the accompanying statements of assets and liabilities of New
England Zenith Fund (the "Fund") (comprising, respectively, the Back Bay
Advisors Bond Income Series, Capital Growth Series, Back Bay Advisors Money
Market Series, Westpeak Stock Index Series, Back Bay Advisors Managed Series,
Goldman Sachs Midcap Value Series (formerly Loomis Sayles Avanti Growth
Series), Westpeak Growth & Income Series, Loomis Sayles Small Cap Series,
Loomis Sayles Balanced Series, Morgan Stanley International Magnum Equity
Series, Salomon Brothers U.S. Government Series, Salomon Brothers Strategic
Bond Opportunities Series, Davis Venture Value Series, and Alger Equity Growth
Series--the "Series"), including the portfolio of investments, as of December
31, 1998, and the related statements of operations for the year then ended,
changes in net assets and financial highlights for each of the two years then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for other periods indicated herein were
audited by other auditors whose report dated February 14, 1997 expressed an
unqualified opinion on these statements.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of December 31, 1998, by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Series constituting New England Zenith Fund as of December
31, 1998, the results of their operations for the year then ended, the changes
in their net assets and the financial highlights for each of the two years
then ended, in conformity with generally accepted accounting principles.
