Dear Shareholder:                                  

Change, opportunity, and stability -- three words with very different
meanings. And yet they work together to highlight the challenges that every
company faces in striving to provide exceptional value and earn the confidence
of customers. 

John Hancock has a long tradition of adjusting to changing markets and creating
and renewing opportunities for our customers. Over the past few years, the
Variable Series Trust has experienced a dramatic transformation in the numbers
of investment options and investment managers available to shareholders. The VST
has grown from three John Hancock investment managers in 1995 to 15 of the
nation's leading money managers, including Independence Investment Associates,
Inc. and John Hancock Advisers, Inc. During the same period, the VST has
expanded from nine investment options to 23. 

Why the changes? Because today's financial services consumer demands more than a
"one size fits all" approach. You want more choices and greater flexibility to
shape an investment strategy that's suited to your asset allocation requirements
as well as your investment personality. 

Of course, these enhancements did not take place on their own. The VST has grown
to more than $10 billion through the dedication and stewardship of leaders like
Hank Shaw, the former Chairman of the Board. After 40 years with John Hancock,
Hank retired recently. We are sad to see him go, and we wish him all the best.

Michele G. Van Leer, Chairman

Since Hank's departure, the transition has been quite smooth. With a newly
elected Chairman in place, we are committed to continuing the style of
leadership and attention to detail that has propelled the VST's success over the
past several years. We look forward to serving as a catalyst for additional
changes that enhance the value of John Hancock's variable life and variable
annuity products. We will strive to maintain a broad range of outstanding
investment options within the VST. We will oversee a rigorous performance review
process to ensure that the VST's subadvisors apply appropriate risk controls.

And so, while the investment climate is ever changing, one thing remains
constant: John Hancock's commitment to delivering value through quality products
and responsive service.


Sincerely,

 Economic Overview: Annual Review 1998
 John Hancock Economic Research
1998 was a tumultuous year in which the economy defied expectations and turned
in another stellar performance despite the drag from a sharply higher trade
deficit and financial market turmoil. Growth was clocked at more than 3.5%,
for the third straight year, a remarkable achievement given that the current
expansion is over seven years old. Once again, analysts are calling for slower
growth this year.
 
The financial crisis which struck Asia in 1997 made landfall in the US during
the first half of 1998, lopping almost 1.5% off Gross Domestic Product (GDP)
growth for the year. The damage came from a precipitous decline in exports,
especially to Asia, as exports fell 5%. Import volumes surged, but the dollar
value of import growth was far more modest because of the strength in the
dollar and deflation in traded goods prices. Import prices fell 6% and were
largely responsible for consumer prices rising only 1.6%.
 
As a consequence, US manufacturing was subject to intense competitive
pressure. Unable to raise prices, manufacturers cut costs by boosting
productivity more than 4% through expanding investment and slashing jobs.
 
In the second half of the year, Russia's default on its sovereign debt
instigated a sudden, sharp reassessment of risk by investors which sent risk
spreads soaring and set off a chain of events that led to the near liquidation
of a high profile hedge fund and gridlock in US capital markets. The stock
market fell by 20%, credit spreads on corporate debt exploded, and some
companies were unable to issue debt at any price for a short period last fall.
 
But, the Fed came to the rescue with three interest rate reductions, for a
total of 75 basis points, which restored confidence, and markets began to
recover. While the stock market had regained all its losses and more by the
end of the year, debt markets were slower to bounce back. Interest rates,
hovering around 5.75-6.0% in the first half of the year, sank to a record low
of 4.7% at the peak of the turmoil in October, before rebounding to around
5.2% at the end of the year.
 
The net effect on the economy was minor and growth actually accelerated
through the last two quarters of the year. Wall Street's problems proved too
transitory to spill over onto Main Street. When firms had trouble lining up
financing, banks jumped into the breach while others were able to wait until
markets revived.
 
Events in 1998 suggest that the strong growth experienced by the economy was
not well-balanced. Domestic oriented, interest sensitive, and consumption
based sectors in the economy prospered while manufacturing and internationally
related sectors suffered. Supported by strong income growth, low interest
rates, tightening labor markets, and a resilient stock market, consumption
spending growth of more than 4% and a strong housing market pulled the rest of
the economy along, as investment moderated somewhat during the year and the
trade deficit proved to be a significant drag.
 
However, a number of cracks in the economy's foundation could prove
troublesome in the future. Consumption has continued to roar ahead, but
increasingly at the expense of savings. By the end of the year, households
were spending more than their labor income, leading to a negative savings
rate. Investment remained healthy but began to sag from potential
overcapapcity, gyrations in the cost of capital, and declining corporate
profitability. As noted above, trade remained weak and is still vulnerable to
further setbacks overseas.
 
The economy seems to face two new risks this year. Corporate profitability
exhibited little growth in 1998 and is not expected to improve much this year,
which could undermine the stock market and the economy. A weaker stock market
could dent consumer spending and business investment, while firms could also
cut back production and jobs in response to poor profit prospects.
 
Another potential trouble spot for the economy is the international exchange
value of the dollar. The dollar began to decline towards the end of 1998 and
is likely to continue into 1999. If this weakness picks up steam and the
dollar falls substantially, we could see interest rates rise and inflation
start to pick up, neither of which would be good for the economy.
 
The economy started 1999 in fine mettle, but the risk that it comes unglued
this year seems larger. It has been blessed with luck and the positive effects
of a prolonged virtuous cycle. How long this can continue is anyone's guess.

 The U.S. economy turned in another solid year in spite of the turmoil roiling
Asia, Russia and Latin America. Real GDP for 1998 is estimated to be between
3.50% and 4.00%, similar to the growth registered in 1997, while the change in
the Consumer Price Index (inflation) was running at a 1.5% pace through
November, compared to 1.7% for 1997. In a dramatic reversal of monetary
policy, the Federal Reserve lowered the Fed Funds target rate three times
within a span of seven weeks in light of the global economic situation and
liquidity crunch. In total, the Fed cut 75 basis points off the Fed Funds
target rate bringing it to 4.75% from 5.50%. The Fed's actions worked
tremendously in restoring confidence to the battered financial markets.
 Our strategy during the year reflected our position that the Fed was not
going to raise rates even though their policy bias during most of the year was
such. We had felt that the economy had not borne the full effects of the Asian
situation and as a result, we expected a modest decline in economic activity
negating the need for monetary tightening. We were investing with a neutral
strategy, acquiring some one-month and three-month adjustable rate securities
as well as investments further out on the short-term yield curve when
attractive. The difference in the short-term investment curves of 30 days out
to 90 days (a representative curve of money market investments) turned in an
average yield difference of incredibly only 1 basis point (1/100 of 1%) over
the entire year. It was a difficult market to extend the Portfolio's maturity
as a result.
 The Portfolio was invested predominantly in commercial paper, representing
approximately three-quarters of the Portfolio with adjustable rate securities
making up another ten percent. The Portfolio is diversified among many
industry sectors and companies.

 Short-Term Bond Portfolio (formerly Short-Term U.S. Govt) Independence
 Investment Associates, Inc.                                       Tom Spicer
 After experiencing the global fallout of economic shocks in Asia, Russia, and
Latin America, heightened concerns over political leadership worldwide, and a
20% correction in U.S. equity markets, bond investors expected the last
quarter of 1998 to be relatively calm. What followed, however, tossed the
fixed income markets yet again for the fourth quarter.
 The corporate bond market began the fourth quarter with a very negative tone.
This significantly increased all spreads in the corporate market and resulted
in a complete lack of liquidity. Bond investors simply flocked to the safety
and security of U.S. Treasury debt. Thankfully, the Fed's surprise rate cut on
October 15th improved investor confidence in the capital markets. With spreads
now wider by 80 to 100 basis points since the end of June, investors re-
entered the corporate bond market and focused on large, liquid, high quality
companies in stable, defensive industries. While corporate bond issuance
surged to an all time monthly record, the sector also posted its largest
monthly outperformance over U.S. Treasuries ever recorded, ending the year on
a strong note.
 The Short-Term Bond Portfolio began the quarter with a weighting in the
corporate sector neutral to that of its benchmark. As the sector regained its
momentum, the position was increased into an overweight with higher quality,
liquid issues being the main purchase candidates. However, the portion of the
Portfolio invested in lower-quality, less liquid issues had a rough time
during the downturn and had still not recovered fully by year-end. These
positions were the main contributor to the Portfolio's underperformance during
the quarter and for the year.
 Over the past twelve months, the performance and behavior of the global
financial markets was fascinating. We have witnessed bull and bear markets,
currency devaluations, global political leadership instability, weaker
corporate earnings projections, and countries defaulting on their debt
obligations. Each of these unexpected events dramatically changed risk
premiums for fixed income investors. As we enter 1999, we would like to
believe that market volatility and bond risk premiums will decrease. While
these uncertainties still exist, however, we feel that maintaining a
relatively liquid, high quality, defensive portfolio is fully justified at
this time.

 The Portfolio continues to meet its investment objective: to match the
performance of the Lehman Brothers Government Corporate Index, which includes
only U.S. dollar-based, fixed coupon debt from the U.S. Treasury, U.S.
Agencies and investment-grade corporations. Performance net of fees for the
Portfolio was 0.16% for the past month, -0.34% for the past quarter and 10.96%
from inception. The corresponding returns for the benchmark are 0.24%, 0.13%
and 7.29%. The Portfolio uses a representative sample of issues selected
through proprietary quantitative techniques. Selected issues have the best
risk-adjusted expected return and, as a group, match the characteristics of
the 6,500 issues in the Index including price sensitivity, industry, and
quality exposures. An indexed portfolio typically eliminates many risks
associated with active management and has lower fees and expenses.
 December proved to be a relatively quiet finish to an eventful year. For much
of the year, fundamental factors took a back seat to international events. The
unpredictable nature of international events and investor reactions propelled
highly diversified and higher-quality portfolios to relatively stronger
performance. Treasury yields dropped dramatically as a result of global
financial stress and the related flights to quality and liquidity. By year-end
, the thirty-year U.S. Treasury issue was above, but near, 5%. However, the
"flights' did not carry over into the corporate sector. During the flight to
liquidity, corporate bond investors widened credit spreads dramatically.
 The mood of the bond market changed in the fourth quarter. Spreads narrowed
late in the year when the use of Treasury issues as a "safe haven' subsided.
Spreads have not recovered completely, and liquidity has not returned to the
market from pre-flight levels. Such uncertainty in the markets increases the
risk associated with predicting yield movements or determining which sectors
will perform well. The highly diversified approach of "Indexation' should
serve investors well in 1999.

 Sovereign Bond PortfolioJohn Hancock Advisers, Inc.                 James Ho
 1998 was an exceptionally challenging year in both the US and international
bond markets, despite the fact that interest rates in the US and virtually all
other Sovereign countries declined to historically low levels. The year could
also be characterized as one in which those strategies that focused on spread
product underperformed, while those positioning duration strategies,
particularly in the US Treasury market, dominated returns. Within the US
markets, corporate bond and mortgage backed yield spreads widened
significantly versus Treasury issues during much of the year, though the
fourth quarter, particularly the month of October, was the most vexing.
 In the fourth quarter, against this backdrop, the Portfolio outperformed its
benchmark, the Lehman Brothers Government/Corporate Index, at 0.31% versus
0.13%, respectively. However, its year-to-date return of 8.23% lagged the
9.47% return posted for the Index. As the Index has a heavier allocation to US
Government and Agency issues, underperformance during a period in which
investors fled to the safety of US Treasuries was not surprising.
 As the year drew to a close, we took the opportunity to capitalize on
compelling and historically wide spreads, representing levels not seen since
1990, and increased our position in corporate bonds. By year-end, the
Portfolio's US Treasury bond holdings were pared down to 22% from a high
allocation of 32% during August, with the expectation that as yield spreads
narrowed versus US Treasuries in 1999, the Portfolio would be handsomely
rewarded.
 Currently, we believe that the Portfolio is not only well diversified, but
also well positioned to benefit from an improvement in investor sentiment, a
tightening in yield spreads and an increase in market liquidity during the
period ahead. Though we believe the market is still subject to near term
market risks, we remain optimistic in our overall view of the bond markets.

 Strategic Bond Portfolio Portfolio

 Early in 1998, it seemed the Asian financial situation was beginning to
settle as global bond markets rallied. However, the crisis continued to spread
in the second half of the year affecting markets world wide. The Russian
currency breakdown and forced liquidation of assets threatened the stability
of the global financial system, providing the catalyst for coordinated action.
Led by the prompt and successive easing moves by the U.S. Federal Reserve,
central banks, governments and supranational institutions around the world
collectively responded to the crisis, restoring investor confidence near the
end of the year.
 Within the U.S. portion of the Portfolio, our decision to increase corporate
and mortgage backed securities during the year benefited performance. In
addition, our decision to maintain the Portfolio's long duration position also
contributed positively to performance. The Portfolio's allocation to U.S.
Treasuries in the third quarter enhanced returns as investors "fled to
quality' from the continued Asian contagion. As corporates and residential
mortgages performed particularly well toward the end of the year, we modestly
reduced the Portfolio's exposure to these sectors.
 Within the foreign markets, our allocation to Continental Europe throughout
the year benefited the Portfolio's performance as the ongoing Asian financial
crisis prompted strong demand for high-quality sovereign bonds. In mid-year,
we decreased the Portfolio's combined allocation to domestic high yield and
emerging markets to 3% and maintained this allocation through year-end. During
1998, the high yield sector was one of the better performing sectors and
emerging markets bounced back late in the year.
 The bond market outlook remains attractive in the U.S., although strong
consumer data, a firm labor market and rebounding stock market all suggest
further interest rate cuts might come later in 1999 than previously expected.
A similar picture is emerging in Europe, with rate cuts expected during 1999,
but against a less buoyant economic backdrop.

 High-Yield Bond Portfolio
 Wellington Management Company, LLP                     Crawford/Smith/McEvoy
 The high yield market stabilized during the fourth quarter as the extreme
volatility that arose during the third quarter subsided. This was illustrated
by a return of +2.1% for the high yield market (Lehman Brothers High Yield
Index) which was well above the +0.3% return of the investment-grade market
(LB Aggregate Index). Fears of further emerging market turmoil and hedge fund
liquidations receded and helped improve liquidity. As of December 31, the
spread of the Lehman High Yield Bond index over the 10-year Treasury was 588
basis points compared to 604 basis points on September 30. High yield
essentially "earned its yield" during the quarter and spreads still remain
significantly wider than in early 1998.
 As the market stabilized, the Portfolio's average quality and emerging market
exposure accounted for the Portfolio's outperformance versus the Lehman HY
Index during the fourth quarter. The average quality rating of the Portfolio
remained at B2 compared to B1 for the Lehman HY Index. During the quarter, the
lower quality "B" sector outperformed the "BB" sector, rewarding risk-taking
investors. Emerging market bonds bounced back in the fourth quarter to
outperform domestic high yield bonds. The JP Morgan Emerging Market Index
(EMBI+) returned +9.9% for the three months ended December 31, 1998. We used
weakness in the third quarter to add to select emerging markets issues but our
exposure still remains below 5%.
 In the fourth quarter, we increased holdings in domestic-oriented companies,
which are less dependent on exports and should be less impacted by weakening
economies overseas. Holdings in three of these industries--cable,
media/entertainment, and telecommunications--total 42.3% of the Portfolio's
market value, versus 33.7% for the Lehman HY Index. Market weakness in the
second half of 1998 created an opportunity to buy higher quality issues that
had been hard to find or that were expensively valued. We have supplemented
these purchases with a handful of lower quality issues which had been
excessively punished in the market.

 The Portfolio returned 14.77% for the fourth quarter and 20.42% for the year
compared to 14.70% for the INDATA median balanced Portfolio manager in 1998.
Our asset allocation decision to overweight equities after the third quarter
sell-off contributed significantly to fourth quarter performance.
 The equity portion returned 23.77% compared to 21.28% for the S&P 500 in the
fourth quarter. For the year, this portion of the Portfolio returned a very
strong 28.82% compared to the 18.1% return of the median INDATA equity
manager. The big winners in your Portfolio included United Technologies, Home
Depot, MCI WorldCom and Tellabs.
 The overall fixed income portion of the Portfolio returned a strong 8.70% in
1998. The US fixed income portion returned 8.18% for the year. Your bond
Portfolio had a 20% exposure to international bonds during the quarter. The
international bond exposure enhanced the performance of the fixed income
portion by 34 basis points during the quarter and 52 basis points for the
year. Over weighted currency positions in Deutsche marks, Swiss francs,
Japanese yen and British pounds had a significant positive performance impact.
 The U.S. equity market rebounded strongly in the fourth quarter but fixed
income markets failed to rally. As a result, we would expect to move from an
over weighted equity position to market weighted asset allocation position
during the first quarter 1999. Within the US equity market, we are favoring
consumer cyclicals, technology and financials and under weighting basic
material and energy stocks. In fixed income, we expect interest rates to
decline and quality spreads to narrow. While we should expect continued
volatility in the capital markets, the long-term outlook of steady growth,
strong consumer spending and low inflation should continue to be positive for
the U.S. stock and global fixed income markets.

  The stock market rebounded strongly from its third quarter lows as two
interest rate cuts by the Federal Reserve restored investor confidence in the
1999 economic outlook. The market advance was broad and your Portfolio
outperformed its benchmark for the fourth quarter and full year 1998.
  The year was extremely volatile and there were vast divergences in
performance between styles, capitalization levels, and P/E groups. For
example, for the full year, "Growth" style far outperformed "Value" style.
High P/E stocks did better than low P/E stocks and large capitalization stocks
did better than small capitalization stocks. The environment, with the
divergences and volatility, was treacherous. Based on preliminary competitive
data, your account did much better than the average manager's.
  Some strong areas in the market were the health care, telecommunications,
technology, and financial groups. In particular, our individual stock
selection was good in those areas. Stocks like Home Depot, MCI WorldCom,
HealthSouth, Compaq Computer, Northern Telecom, and Merck led in performance.
Some areas of the market that did not do well were the energy and electric
utility groups. Oil prices declined sharply in the fourth quarter due to
oversupply and continued weakness in Asia. Electric utilities, which did well
in the third quarter because of their defensive characteristics, did not do as
well in the strong fourth quarter environment.
  So, now that the year is behind us, what lies ahead? Our economic forecast
calls for a slowing of the economy from the +3.8% level to 1.5-2.0% in 1999.
This means that first half earnings comparisons will be tough, but easier in
the second half. Inflation should remain low due to low oil prices and a
slowing of economic activity. Therefore, we do not expect interest rates to
move upward--they will likely stay in the range of 4.8%-5.6%. We expect that
the stock market will be continually reacting to the balance between earnings
growth and the level of interest rates. We believe Asia has bottomed. It will
not recover soon.
  Within this environment, our strategy is the same. We will build portfolios
that consist of stocks that have attractive value and improving fundamental
trends. This strategy has served our clients well for 18 years and especially
well in a treacherous 1998 environment. We also will continue to manage risk--
no big sector bets, cash timing, and market-like volatility.

 Large Cap Value Portfolio T. Rowe Price Associates, Inc.     Brian C. Rogers
 Positive economic growth, a favorable interest rate environment, and
substantial stock market volatility characterized last year. A solid first
half was undermined by a severe third quarter correction, which gave way to a
near-euphoric rally in the final months. The S&P 500 Index advanced by more
than 20% for a record fourth consecutive year. However, within the context of
another strong year for equities, there were significant crosscurrents that
had a major impact on the performance of many sectors of the market.
 For the year, the Portfolio return produced respectable but somewhat
disappointing results, since it was the first time in a while that performance
lagged the Morningstar peer group. During the broad market advances we have
seen in recent years, it is extremely difficult for portfolios with
conservative objectives like Large Cap Value to keep up with S&P 500 stocks.
In times such as these, it is helpful to keep in mind that the purpose of this
type of Portfolio is not to generate robust returns under all market
conditions. The goal is to produce attractive returns, including substantial
dividend income, over time and also to help cushion investment principal when
times get rough.
 The Portfolio was 95% invested in equities at year-end. Three of our largest
sales during the past six months were stocks of companies that were in the
process of being merged or acquired. In each case, we were able to sell our
shares at prices higher than our original cost.
 We made significant new investments in several companies, including Baker
Hughes, Boeing, and BankAmerica, all of which we bought at prices well below
their highs for the year. Many of our holdings typically trade at below-
average valuation levels because, for many diverse reasons, their share prices
declined before we took a position in them. This investment strategy, buying
out-of-favor stocks with good long-term potential, has served shareholders
well in the past, and we believe it will continue as a successful strategy in
the future when investors focus again on stocks with appealing market
valuations.
 Among the Portfolio's largest holdings are companies from many diverse
industries, including SBC Communications, Mellon Bank, American Home Products,
Exxon, Anheuser-Busch, Dow Chemical, GE, and others that represent a broad
cross-section of the U.S. economy.
 Twelve months ago, we commented on the rapid appreciation of stock prices
compared with the growth in the underlying earnings and dividends. In 1997,
share prices increased at a much faster rate than the underlying fundamentals,
and this "delinkage" between price and value grew even more pronounced in
1998.
 We expect 1999 to be a more challenging year than the one that just ended. In
our view, this could lead to more moderate returns than the robust and
unsustainable performance of the past four years. In this environment, our
investment approach will be steady and constant, as always. We will continue
to search for attractively valued stocks with solid long-term potential.

 Large Cap Growth PortfolioIndependence Investment Associates, Inc.      Mark
 Lapman
 The Large Cap Growth Portfolio returned a very strong 27.79% in the fourth
quarter. For the full year of 1998, the Portfolio returned 39.51%, well ahead
of the S&P 500 return of 28.57% and the INDATA median large cap growth manager
return of 19.0% for 1998.
 The stock market turned in an extremely strong fourth quarter as interest
rate cuts in the U.S. and other countries buoyed investor confidence.
Technology and specialty retailer stocks led the fourth quarter rebound as
companies such as Lucent Technologies, Autodesk, Home Depot and Lowes
performed very well. We remain confident that we will outperform other growth
funds by owning growth stocks with better growth prospects at a less expensive
price.
 The key factors driving stocks today is consumer and financial liquidity. We
believe consumer spending will remain strong as wage growth outpaces inflation
by a comfortable margin in 1999. Consumer confidence is still very high and
the federal budget has swung from a deficit to a surplus. The safety net for
the economy continues to be the Fed and its interest rate policy. In the event
that emerging market turmoil causes another financial crisis, the Fed can
still comfortably cut the Fed Funds rate as much as another 1.5% to
reinvigorate the economy.
 We expect 1.5% U.S. GDP in 1999 and a rebound in corporate profit growth
beginning in the second half of 1999. Technology companies will be the major
source of the earnings rebound in 1999 which should bode well for large
capitalization growth stocks. Strong consumer spending will continue to
benefit well-positioned specialty retailers. While we should expect continued
volatility in the stock market, the long-term outlook of steady growth and low
inflation should continue to be positive for large capitalization growth
stocks.

 Equity Index Portfolio  State Street Global Advisors         Management Team
 
 The Equity Index Portfolio had a tremendous fourth quarter in 1998. The fund
rose 21.27% during the quarter. This rebound reversed the losses suffered in
the third quarter and also contributed to the total year's return of 28.45%.
The Portfolio has returned just over 57% since May 1, 1997.
 1998 is the fourth consecutive year in which the S&P 500. Index returned more
than 20%. The Index return was 37.58% in 1995, 22.96% in 1996, 33.36% in 1997,
and 28.58% in 1998. To put this in perspective, $1.00 invested in the S&P 500.
Index at the beginning of 1995 would now be worth $2.90.
 The Equity Index Portfolio continued to grow during the year. At the
beginning of 1998 the Portfolio's total value was approximately $101 million.
At the end of 1998 the value was over $230 million. Much of that gain came
from new money into the Portfolio, while market returns contributed the
remainder.
 The Equity Index Portfolio attempts to track the performance of The S&P 500.
Index by fully replicating the index. The fund attempts to match the index
holdings and weights for each name in order to provide returns close to the
index return.

 Real Estate Equity Portfolio Independence Investment Associates, Inc. Dalton
 Avery
 The commercial real estate markets achieved equilibrium during 1998. REIT
stocks were strong performers during the years of the real estate recovery but
equilibrium caused a number of investor concerns, which was reflected in the
disappointing performance of the REIT Group during the year. Concern about new
development and supply coincided with expectations of a downturn in the
overall economy. This, in turn, raised fears of another overbuilding period
that caused the real estate downturn in the early 1990's. While the REIT
stocks weakened many companies continued to issue additional shares. The
combination of the flight of momentum investors with new stock issuance
exacerbated the downturn in stock prices. A shift of investors from
growth/momentum owners to value/yield investors was not a smooth transition
and REIT share prices reflected this disconnect.
 The outlook for 1999 is favorable now that return expectations for REITs have
moderated. The group started the year yielding 7%. Concerns about the overall
economy have abated so real estate fundamentals remain attractive. In
addition, the commercial mortgage crisis (CMBS) that occurred in mid 1998
reduced the supply of capital for real estate development. This reduced
capital availability has curtailed a number of new developments and tempered
the amount of new property supply coming to the market in 1999 and 2000. An
improved economic outlook will be favorable for tenant demand while the
reduced supply of new real estate combined with stock prices that reflect low
expectations should eventually attract new inflows of capital to REIT stocks.

 Mid Cap Value PortfolioNeuberger Berman, LLC        M. Kassen & R. Gendelman
 In 1998, growth outperformed value on every level of capitalization. In fact,
the capitalization effect and growth leadership produced the widest
disparities ever in returns between large, mid and small stocks, and between
growth and value stocks.
 It is no wonder that under these conditions, 86% of Portfolio managers
underperformed the broad-based market. The Russell Mid Cap Value Index
underperformed the Russell Mid Cap Index by 5% (5.1% to 10.1%) while the
growth index showed an absolute return of 17.9%. The Neuberger Berman Mid Cap
Value Portfolio returned 12.2% for the quarter and -10.5% for the year (gross
of fees).
 Similar to the S&P, the large cap companies in the Russell Mid Cap Value
Index (greater than $7.8 billion) contributed 128% of the Russell Mid Cap
Value's return for the year. These 65 securities represent 9% of the names in
the index and 30% of the market cap weight.
 Your Portfolio's top performing sector for the quarter was Producer Durables
with an absolute return of 51.4% (the sector contributed 2.3%). For the year,
Health Care (51.3%) was the top-performing sector and the top contributor
(3.4%). Your Portfolio was aided in the fourth quarter by an increase in
Teradyne. The largest contributor for the year was Biogen.
 Stocks, which lost value in the quarter included CompUSA and McDermott
International. Generally, the most damaging stocks for the year were companies
operating in cyclical industries.
 In spite of the large capitalization and growth orientation of the markets in
1998, we will continue to adhere to our midcap value approach to investing
that has served our clients well over long periods of time. For 1999, we will
be slower to sell our better performing positions as long as fundamentals
remain intact. Secondly, we will not add or initiate new positions based
solely on inexpensive valuations. Lastly, we will be more disciplined in our
sell process.

 Mid Cap Growth PortfolioJanus Capital Corporation                   Jim Goff
 Equity markets rebounded to reach new highs in the fourth quarter. Federal
Reserve interest rate cuts and a resilient economy helped stocks shake off
uncertainty over presidential impeachment, economic problems abroad, and
pressure on corporate earnings. In this environment, investors increasingly
focused on companies with visible earnings, regardless of size. Consequently,
most of our midcap stocks participated in the rally.
 Turning to the Portfolio, we are pleased to report that we outpaced our
benchmark, the Russell Mid Cap Growth Index, reflecting strong gains by our
technology, media, and pharmaceutical positions. Among our technology
holdings, Vitesse Semiconductor soared on robust demand for its specialty
gallium arsenide semiconductors, a very high-speed, high-frequency chip used
in the growing voice and data communications market. In the media arena,
companies such as radio conglomerate Jacor Communications and billboard
company Outdoor Systems shook off recession fears to rebound solidly. In both
the radio and outdoor media sectors, consolidation continued to drive revenue
growth, making earnings less vulnerable to advertising budgets and the
economy.
 In the pharmaceutical industry, our position in Sepracor was a standout. The
company reformulates and patents single-isomer versions of existing drugs in a
procedure that eliminates many of the drugs' negative side effects. Sepracor
has improved a number of compounds and recently signed an agreement with Eli
Lilly for Prozac. On the downside, we were disappointed with the performance
of Paychex, a payroll processing company, which declined on concerns over a
potential slowdown in employment growth.
 Looking ahead, we believe that this market is playing directly to our
strengths of strong research and the ability to identify all-weather growth
companies. As many large capitalization companies see their profit margins
erode, the key will be to own those companies that can meet or exceed Wall
Street's estimates. In this environment, we believe small and midcap companies
continue to offer significant opportunities.

 Diversified Mid Cap Growth Portfolio (formerly Special Opportunities) John
 Hancock Advisers, Inc.                                      Barbara Friedman
 For 1998, the Diversified Mid Cap Growth Portfolio returned 5.61%,
underperforming the Russell Mid Cap Index return of 17.86%. Several factors
accounted for this underperformance. First, we significantly repositioned the
Portfolio during the first half of 1998 bringing it into a truer midcap format
and away from the combination of small and large cap stocks that previously
dominated the Portfolio. During this period, the Portfolio's performance
matched the Russell Mid Cap Index, but did not match its peers outperformance.
We also included holdings of REITs and gas distribution stocks which performed
well in 1997, but failed to do so in 1998.
 Secondly, during the repositioning, we were slow to take a position in
technology stocks which were the major contributors to the year's performance.
We addressed this issue during the fall, taking the technology sector from a
market to an overweight position. For 1998, 8 of the top 10 performers were
technology stocks, including EMC Corp, Lexmark, and Compuware.
 Most importantly, we focused too narrowly within the smaller portion of the
midcap universe to ensure the Portfolio stayed within its midcap mandate. For
most of this year, some 50% of the Russell Mid Cap Index weighting has been
outside and above the top end of the Portfolio's market cap limit. This 50%
weighting produced over 86% of 1998 return of the index. Beginning in mid
December, we more carefully and aggressively invested the 28% or so of the
Portfolio's available assets in these larger cap names in the Russell midcap
universe.
 1998 was truly a year of transition--if not, 1 1/2 transitions. However, as
we enter 1999, the Portfolio has strong characteristics with projected
earnings growth some 50% better than that of its large cap counterparts and
selling at a modest discount to the large cap market. These domestically
oriented companies should not be fundamentally hurt by financial crises
outside the US and should continue to benefit from a growing US economy where
both inflation and interest rates remain low.

 Small/Mid Cap CORE Portfolio
 Goldman Sachs Asset Management                            Jones/Clark/Pinter
 For the quarter ended December 31, 1998, the John Hancock VST Small/Mid Cap
CORE Portfolio ("Portfolio") returned 15.94% at NAV, underperforming its
benchmark, the Russell 2500 Index ("Index"), which returned 17.40%. Since
inception (May 1, 1998), the Portfolio returned -9.81% at NAV, slightly
underperforming the Index, which returned -9.30%. The primary reasons for the
Portfolio's underperformance stem from its smaller market capitalization bias,
its value-oriented methodology and stock selection.
 Small capitalization stocks rallied during the fourth quarter, as the credit
crunch in capital markets and concerns about global financial conditions were
eased, in part, by the Federal Reserve Board's successive rate cuts. However,
the impressive fourth quarter Index return of 17.4% was overshadowed by the
S&P 500 Index return of 21.3%, as investors continued to favor the quality and
perceived safety of blue-chip, large capitalization companies. Investors also
continued to prefer growth versus value investing; the Russell 2500 Growth
Index return of 25.4%, significantly outperforming the Russell 2500 Value
Index for the quarter, which appreciated only 11.2%.
 On a sector basis, our positions in healthcare, technology, consumer
services, commercial services, telecommunications and transports positively
impacted performance during the quarter. The energy sector, however, detracted
from performance, partly due to increased uncertainty from weakening oil
prices and industry consolidation.
 We seek to add value through individual stock selection while sector
weightings and distribution among size categories continue to approximate
those of the Index. We prefer stocks with attractive valuations, lower-than-
average risk, good momentum and favorable analyst opinions. Over the long-
term, these factors have led to excess returns, although they often may not
simultaneously work well. During the fourth quarter, the strongest performers
were stocks with high valuations and higher-than-average risk. As these
characteristics are contrary to our investment style, the Portfolio's
performance was negatively impacted.
 We anticipate that 1999 will predominantly be a year of transition, with
growth slowing as the year progresses and interest rates dropping after the
first half of the year. Despite possible continued volatility in the U.S.
equity markets throughout 1999, we believe that through our combined
qualitative and quantitative stock selection strategy and our disciplined,
long-term approach, the Portfolio has the potential to generate solid long-
term returns.

 Small Cap Value Portfolio INVESCO Management & Research         Bob Slotpole
 The equity market roared back with the best quarterly return for the Standard
& Poor's 500 since 1975. The Russell 2000 Index returned 16.3%, but still
finished in negative territory for the year. Technology stocks were the biggest
winners, as companies with ".com' in their names reached the ozone layer. This
sector is likely to remain unusually volatile until investors can put some
bounds around the growth potential of commerce on the web. Contrasted with this
euphoria are the hard times that have befallen commodity producers. Problems
are particularly evident in energy, where a combination of warm weather and
collapsing Third World demand have driven prices to lows not seen since the mid
1980's.
 The Small Cap Value Portfolio returned 14.2% for the quarter and -5.96% for
the year, versus 16.3% and -2.55% for the Russell 2000. The shortfall was
largely due to the Portfolio's value bias; the degree to which growth stocks
outperformed value in 1998 was unprecedented. While the Russell 2000 Value
Index fell -6.5%, the Russell 2000 Growth Index was up 1.2%--the widest
dispersion between the two in their 22 year history. Although our stock
selection tools that focus on valuation have hurt recent results versus the
broader index, over time these factors have proven to be valuable contributors
to excess return.
 Despite recent weakness, small cap stocks can offer significant benefits to
long-term investors. Historically they have provided excess returns of 3%
annually over large cap stocks for 5 year holding periods and they contribute
to overall portfolio diversification. Currently, the Russell 2000 is trading at
a discount to the S&P 500 on a forward earnings basis and relative measures of
price/book and price/earnings have reached new lows. Such compelling valuation,
combined with lower interest rates, presents a very favorable climate for small
cap stocks.

 Small Cap Growth Portfolio John Hancock Advisers, Inc.         Bernice Behar
 1998 was an outstanding year for the Small Cap Growth Portfolio. Despite the
market bias toward large cap stocks, the Portfolio gained 14.5%. This
performance exceeded the 1.2% return of the Russell 2000 Growth Index by a
wide margin. Holdings in the Technology and consumer related sectors had the
largest impact on performance.
 We emphasized consumer stocks during the year for several reasons. Low levels
of unemployment, inflation, and interest rates and high consumer confidence
created an ideal environment. We purchased several companies in the retail
industry and were particularly successful in the specialty retail segment
(Linens 'N Things, Abercrombie & Fitch). Other consumer holdings included
business services companies that performed well due to an increase in
outsourcing and food and drug stores that were undergoing consolidation
through most of the year (Genovese, Duane Reade).
 The Technology sector was the strongest contributor to performance. During
the year we made strategic shifts within the overweighted sector based on
underlying fundamentals and current market conditions. These decisions
significantly added to performance. In the first half of the year, the Asian
crises created uncertainty in the market. We correctly concluded that
companies with higher earnings visibility would perform well. We focused the
Portfolio on software and services stocks, whose earnings are more consistent,
and avoided the more cyclical semiconductor related stocks. After the market
decline in July, we added higher quality semiconductor names. We felt their
current stock prices reflected most of the negative sentiment. These stocks
rallied sharply in the fourth quarter boosting performance. Finally, we took
profits in some of our software and services holdings and purchased several
Internet stocks. These stocks were trading at cheaper valuations after severe
declines during the third and early fourth quarters. The market rewarded these
stocks in the fourth quarter causing their stock prices to soar.

 Equity markets staged an astonishing recovery in the fourth quarter, in many
cases surpassing their previous highs for the year as fears of the end of the
bull market appeared to have been forgotten. For the quarter, the VST Global
Equity Portfolio underperformed the MSCI World Index (US$) by 7%. Since the
Portfolio's inception on May 1, 1998, the Portfolio returned -0.55%
underperforming the benchmark, which returned 7.99%.
 Late in the quarter, Europe took up the running, coordinating a larger-than-
expected cut in interest rates. In contrast to the financial markets
motivation of the US rate cut, the European action was designed to stimulate
slowing European GDP growth.
 However, credit market pressures have not dissipated. Although the $41bn IMF
package for Brazil did much to allay investors' fears in the short-term, bond
market spreads over US Treasuries rose rapidly again at the end of December,
as the Brazilian government failed to pass an important part of their fiscal
reform package. Doubts remain over systemic risk akin to the "Russian" crisis
in the third quarter.
 Some of the fundamental drivers underlying our investment themes are
changing. While restructuring still has considerable potential outside the US,
deflationary risks are becoming more evident. The furious pace of the recent
merger and acquisition activity is inspired by cost cutting and the
elimination of capacity, and, as a defense against deflation, will not yield
the same benefits as earlier restructuring.
 The real risks that we perceive in both the global economy and individual
financial markets have led us to maintain a flexible stance in the Portfolio.
Investment performance has not kept pace with our benchmark index during the
quarter, although it has achieved our anticipated returns.
 In our search for new themes, we are seeking to understand the wider
implications of the latticework of structural imbalances that today
characterize the global economy. In the meantime, the Portfolio will remain
positioned for change.

 International Balanced Portfolio Brinson Partners, Inc.      Management Team
 The International Balanced Portfolio provided 19.09% return (gross of fees)
for the year, which slightly beat the portfolio's benchmark return of 19.04%.
The portfolio's underweight of Japanese bonds was the most significant positive
contributor to results for the year, primarily due to that market's fourth
quarter performance. Overall Portfolio results were hampered by the underweight
of non-U.S. equities in favor of non-U.S. bonds for the year.
 For the fourth quarter, non-U.S. equity markets returned 16.9%, and thus
recouped much of the decline experienced in the third quarter. For the full
year, non-U.S. markets provided 13.8% (in dollar-hedged terms). With the upturn
in the equity markets through the fourth quarter, the majority of individual
European markets ended the year with double-digit returns (in dollar-hedged
terms). Non-U.S. bond markets provided a lackluster 0.6% return (in dollar
hedged terms) for the quarter, with returns ranging from 4.3% and 4.0% in
Sweden and the U.K., respectively, to a low of -5.0% in Japan. Nevertheless,
the one-year returns from non-U.S. bond markets reached a robust 11.5% (in
dollar-hedged terms).
 In the International Balanced Portfolio, we continue to emphasize the non-U.S.
bond markets relative to non-U.S. equity markets. Global equity investors
continue to be confronted with an overextended equity market that pays little
attention to declining profit expectations. We remain very underweight in
Japan, Hong Kong and Singapore. Among non-U.S. bond markets, we have no
exposure to Japan and have maintained overweight positions in Australia,
Denmark, Spain and the U.K. The Portfolio's currency strategies at the end of
the fourth quarter remained neutral. The only notable hedging strategies were
underweights in the Japanese yen and the British pound sterling, and a smaller
underweight of the Hong Kong dollar. Offsetting these positions were
overweights in the Australian and, to a lesser degree, the New Zealand dollar.

 International Equity Index Portfolio (formerly International Equity)
 Independence International Associates Inc.                      Norman Meltz
 The International Equity Index Portfolio returned 20.93% (gross) in the
fourth quarter versus the GDP Index return of 21.56%. Since inception of the
indexing strategy on May 1st of this year, the Portfolio's gross return of
5.43% trails the GDP Index return of 6.40%. Excluding May, when we began
managing the Portfolio and restructured the entire Portfolio, the Portfolio's
gross return of 4.72% trails the GDP Index return of 4.91% by 19 basis points.
 Most of the fourth quarter's performance shortfall came from two sources.
First, during October, when the Fund under-performed the index by 36 basis
points, a steady steam of redemptions caused an underweight in Japan as we
sold Nikkei 225 futures as the source for cash. Japan's performance exceeded
the average of the other 19 countries in October by nearly 5%. Therefore, as
the largest country weight in the Portfolio at more than 30%, this underweight
caused negative tracking.
 The other source for the performance difference in the quarter was stock
selection. Currently, the Portfolio holds 525 stocks while the index includes
1036 stocks. While optimized portfolios track well over longer time periods,
tracking error in shorter periods does vary. Since we completed restructuring
this Portfolio in May, we have maintained a predicted annual tracking error of
less that 0.45% as measured by the BARRA risk model. Over the period since
June, that prediction has been true.
 Over the next quarter we will attempt to reduce monthly tracking error in two
ways. First, if Portfolio purchases and sales permit, we will add more stocks
to the Portfolio. Second, we will utilize FT100, CAC40 and DAX futures in
addition to Nikkei 225 futures. The FT100 tracks the UK market, the CAC40
covers France and the DAX covers Germany. Thus, we can raise cash by using a
basket of countries rather than just Japan. That will allow us to reduce the
disruptive effect redemptions have on the Portfolio's country weights.

 For the year, the MSCI EAFE benchmark was up 20%, helped by dollar weakness
that contributed about one-third of the gain. Europe, up 29%, was the
strongest international region in 1998, while Latin America, down 35%, was the
weakest. Latin America suffered the savage sell-off that afflicted the Far
East last year as "Asian contagion", exacerbated by the Russian default and
devaluation, induced a loss of confidence in Brazil and the region.
 Looking forward, we see international economies growing more slowly. Our
cautious stance in the Pacific and Japan will help shield the Portfolio from
the pain that those markets must go through before they can emerge as
fundamentally healthy investment centers.
 Corporate activity and restructuring in Europe are expected to continue as
Economic and Monetary Union (EMU), deregulation, and a weaker economy coincide
in the year ahead. The extent of corporate consolidation in Europe lags the
US, and thus there is further scope for industry concentration. Our enthusiasm
for Continental Europe remains high, as we continue to find businesses with
sustainable growth prospects, managed to maximize returns, at reasonable
valuations.
 The Japanese government's long overdue action in the fourth quarter is
encouraging. We remain underweight, though, because at the stock level there
are relatively few companies focused on shareholder value, willing to take the
tough actions that may be required in the recessionary and deflationary
environment of Japan at present.
 In the rest of the Far East, the bottom of the crisis may be at hand, but we
believe that valuations bear little relationship to the underlying merits of
the stocks. We retain our belief that Latin America offers attractions and
opportunity. The key remains avoiding a disorderly devaluation in Brazil. Our
view is that this is possible, and the Portfolio holdings will, in time, be
able to achieve valuations closer to those of international sector peers.
 Confidence has clearly returned to global stock markets after the difficult
third quarter. Looking ahead, we believe that this renewed confidence, coupled
with healthy if unspectacular economic growth in Europe and signs that we are
at least closer to the bottom in Asia will lead to reasonable performance from
international equity markets in 1999.

 Emerging Markets Equity Portfolio Montgomery Asset Management, LLC.       J.
 Jimenez & B. Sudweeks
 1998 was an extremely volatile year for emerging markets, marked by
exceptional swings in global volatility and investor sentiment. A huge bailout
package by the International Monetary Fund (IMF) announced at the beginning of
1998 offered some respite from selling pressure; however, the positive effect
of the rescue package on the financial markets was offset by a decline in the
value of the Japanese yen later in the year. This slide sparked investor fears
of another round of Southeast Asian currency devaluations like the prior year.
As investment capital left Asia for safer havens during the year, negative
sentiment proved infectious. Emerging markets in other regions also began to
experience capital flight. Capital dependent countries from Brazil to South
Africa were forced to raise short-term interest rates, risking future growth
prospects in order to stabilize their currencies and continue to attract
investors. This resulted in short-term market volatility across the asset
class.
 There were some bright spots in the emerging markets picture, however. With
the exception of Russia, European emerging markets suffered far less
volatility than their counterparts in Asia, Latin America and Africa, and some
continued to achieve good returns. Greece was the standout, benefiting from
the positive investor sentiment currently enveloping European Union countries
ahead of the introduction of the EMU. Poland and Hungary, which are candidates
for accession to the European Union, also gained from the association.
 The performance of the John Hancock Variable Series Trust Emerging Markets
Portfolio was -28.87% since inception (5/1/98), versus -28.92% for MSCI EM
Free Index for the same period. While since inception we have been able to
match the index, during the fourth quarter we gave up most of the value we
added during the initial months of managing the Portfolio. Our fundamental
based quantitative and qualitative approach to investing in this asset class,
which we expect to add value over the long term, was not rewarded during the
fourth quarter when stocks experienced extreme volatility. Our smaller cap
bias in some of the markets adversely impacted performance as we saw the same
trend evidenced in the U.S. and Europe where bigger was better. Also some of
our specific country bets worked against us. For example our underweight in
Korea in the fourth quarter and our overweights in Brazil and South Africa
detracted from our performance. On the other hand, our overweight in emerging
European markets such as Greece contributed to our performance.

JOHN HANCOCK VARIABLE SERIES TRUST I
December 31, 1998
- --------------------------------------------------------------------------------
(000's Omitted)

NOTE A--ORGANIZATION

  The John Hancock Variable Series Trust I (the "Fund") is a diversified open-
end management investment company registered under the Investment Company Act of
1940, as amended. The Fund is organized as a Massachusetts business trust. The
Fund consists of twenty-three portfolios: Large Cap Growth, Sovereign Bond,
Emerging Markets Equity, International Equity Index (formerly, International
Equities), Global Equity, Small Cap Growth, International Balanced, Mid Cap
Growth, Large Cap Value, Money Market, Mid Cap Value, Diversified Mid Cap Growth
(formerly, Special Opportunities), Bond Index, Small/Mid Cap CORE, Real Estate
Equity, Growth & Income, Managed, Short-Term Bond (formerly Short-Term U.S.
Government), Small Cap Value, International Opportunities, Equity Index, High
Yield Bond and Strategic Bond. The Fund may add or delete portfolios in the
future to accommodate various investment objectives. The Fund has issued shares
of beneficial interest exclusively to John Hancock Variable Life Account U
("JHVLAU"), John Hancock Variable Life Account V ("JHVLAV"), John Hancock
Variable Life Account S ("JHVLAS"), and John Hancock Variable Annuity Account I
("JHVAAI") to fund policies and contracts issued by the John Hancock Variable
Life Insurance Company ("JHVLICO"), and to John Hancock Variable Annuity Account
U ("JHVAAU"), John Hancock Variable Annuity Account V ("JHVAAV"), and John
Hancock Mutual Variable Life Insurance Account UV ("JHMVLAUV") to fund contracts
and policies issued by John Hancock Mutual Life Insurance Company ("John
Hancock").

NOTE B--ACCOUNTING POLICIES

  Estimates: The preparation of the financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Valuation of Investments: For the Large Cap Growth, Emerging Markets Equity,
Small Cap Growth, Mid Cap Growth, Large Cap Value, Mid Cap Value, Diversified
Mid Cap Growth, Small/Mid Cap CORE, Real Estate Equity, Growth & Income,
Managed, Small Cap Value, and Equity Index Portfolios: Common stocks and other
such securities traded on national exchanges are normally valued on the basis of
closing prices. Securities traded in the over-the-counter market and securities
with no sales on the day of valuation are normally valued at their last
available bid price.
 
  For the Sovereign Bond, Bond Index, Managed, Short-Term Bond, High Yield Bond
and Strategic Bond Portfolios: Debt investment securities having a primary
market over-the-counter are valued on the basis of valuations furnished by a
pricing service which determines valuations for normal institutional size
trading units of debt securities, without exclusive reliance upon quoted prices.
 
  For the Money Market Portfolio: The Board of Trustees has determined that the
appropriate method for valuing Portfolio securities is amortized cost, so long
as the average weighted maturity of money market instruments comprising the
Portfolio does not exceed 90 days. Accordingly, Portfolio securities are valued
at amortized cost which approximates market value. The amortized cost method
involves valuing a security at its cost on the date of purchase and thereafter
assuming a constant amortization to maturity of the difference between the
principal amount due at maturity and the cost of the security to the Portfolio.
 
  For each of the Portfolios, short-term investments, with a maturity not to
exceed 60 days, are valued at amortized cost which approximates market value.
 
  For the International Portfolios: Investments in securities traded on national
securities exchanges in the United States or on equivalent foreign exchanges are
normally valued at the last quoted sales price on such exchanges as of the close
of business on the date of which assets are valued. Securities traded in the
over-the-counter market and securities traded with no sales on the day of
valuation are normally valued at their last available bid price. All Portfolio
securities initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Currency Translation."
 
  Investment securities for which no current market quotations are readily
available, including certain foreign

NOTE B--ACCOUNTING POLICIES--CONTINUED

securities, when held by the Portfolios, are valued at fair value as determined
in good faith by the Board of Trustees.
 
  Investment security transactions are recorded on the date of purchase or sale.
 Dividend income is recorded on the ex-dividend date and interest income is
recorded on the accrual basis.  Dividend income for the Large Cap Growth,
Emerging Markets Equity, International Equity Index, Global Equity,
International Balanced, Mid Cap Growth, Large Cap Value, Mid Cap Value,
Diversified Mid Cap Growth, Growth & Income, Managed, International
Opportunities, Equity Index and Strategic Bond Portfolios are shown net of
foreign taxes withheld of $26, $6, $442, $13, $42, $7, $14, $5, $4, $235, $131,
$100, $14, and $2, respectively.  Realized gains and losses from security
transactions are determined on the basis of identified cost.
 
  Repurchase Agreements: The Portfolios of the Fund may enter into repurchase
agreements which are contracts under which a Portfolio would acquire a security
for a relatively short period (usually not more than 7 days) subject to the
obligation of the seller to repurchase and the Portfolio to resell such security
at a fixed time and price (representing the Portfolio's cost plus interest).  A
Portfolio will enter into repurchase agreements only with member banks of the
Federal Reserve System and with "primary dealers" in United States government
securities.  The underlying securities, which represent the collateral of the
agreement, must be marked to market daily to ensure that each repurchase
agreement is fully collateralized at all times.  A Portfolio will not invest
more than 10% of its net assets in repurchase agreements maturing in more than 7
days.
 
  Joint Repurchase Agreements: The Sovereign Bond, Small Cap Growth and
Diversified Mid Cap Growth Portfolios of the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Sub-Adviser"), an indirect wholly-owned subsidiary of John Hancock,
may participate in a joint repurchase agreement pursuant to an exemptive order
issued by the Securities and Exchange Commission.  Aggregate cash balances are
invested in one or more repurchase agreements, whose underlying securities are
obligations of the U.S. Government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint repurchase
agreement on the Fund's behalf.  The Sub-Adviser is responsible for ensuring
that the agreement is fully collateralized at all times.
 
  Joint Trading Account: Pursuant to an Exemptive Order issued by the Securities
and Exchange Commission, the order permits the existing Portfolios of the Fund
to pool daily uninvested cash balances, together with the balances of any future
Portfolios of the Fund, into a joint account for the purpose of investing the
cash balances in short-term repurchase agreements, commercial paper and other
short-term investments which in no event will have a maturity in excess of seven
days.  Joint Account holdings as of December 31, 1998:

  Financial Futures Contracts: The Sovereign Bond, Emerging Markets Equity,
International Equity Index, Global Equity, Small Cap Growth, International
Balanced, Mid Cap Growth, Diversified Mid Cap Growth, Small/Mid Cap CORE,
Managed, Short-Term Bond, Equity Index, High Yield Bond and Strategic Bond
Portfolios may buy and sell financial futures contracts to hedge against the
effects of fluctuations in interest rates and other market conditions.  At the
time the Portfolio enters into a financial futures contract, it will be required
to deposit with its custodian a specified amount of cash or U.S. government
securities, known as "initial margin." Each day, the futures contract is valued
at the official settlement price of the board of trade or U.S. commodities
exchange.  Daily variation margin adjustments, arising from this "mark to
market," are recorded by the Portfolios as unrealized gains or losses.
 
  When the contracts are closed, the Portfolio recognizes a gain or a loss.
Risk of entering into futures contracts include the possibility that there may
be an illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Portfolio could be prevented from opening or realizing the benefits of
closing out futures positions because of position limits or limits on daily
price fluctuations imposed by an exchange. At December 31, 1998, open positions
in financial futures contracts were as follows:

   Forward Foreign Currency Contracts: The Fund may use foreign currency
contracts to facilitate transactions in foreign securities and to manage the
Portfolio's currency exposure. Contracts to buy generally are used to acquire
exposure to foreign currencies, while contracts to sell are used to hedge the
Portfolio's investments against currency fluctuations. Neither type of foreign
currency transaction will eliminate fluctuations in the prices of the
Portfolio's securities or prevent loss if the price of such securities should
decline. The U.S. dollar value of a forward foreign currency contract is
determined using forward exchange rates supplied by a quotation service.
Realized gain (loss) on the purchases and sales of forward foreign currency
contracts is recognized on settlement date.
 
   Currency Translation: For Portfolios that trade in international securities:
all assets or liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars based on London currency exchange quotations as of
5:00 p.m., London time, on the date of any determination of the net asset value
of the Fund. Unrealized exchange adjustments are included in unrealized
appreciation (depreciation) of investments. Transactions affecting statement of
operations accounts and net realized gain (loss) on investments are translated
at the rates prevailing at the dates of transactions.

   Reported net realized gains and losses on foreign currency transactions
represent net gains and losses from sales and maturities of forward foreign
currency contracts, disposition of foreign currencies, currency gains and losses
realized between trade and settlement dates of security transactions, and the
difference between the amounts of net investment income accrued and the U.S.
dollar amount actually received.
 
   Dividends: A dividend of its net investment income will be declared and
distributed daily by the Money Market Portfolio. Dividends of net investment
income will be declared and distributed monthly by all other Portfolios. Each
Portfolio will distribute all of its net realized capital gains annually, at the
end of its fiscal year.
 
   Federal Income Taxes: Each of the Portfolios of the Fund intends to comply
with the requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies and to distribute substantially all of its
taxable income to shareholders. Therefore, no federal income tax provision is
required.

   As of December 31, 1998, the Fund had approximate net tax basis capital loss
carryforwards, which may be applied against any net taxable gains, as follows:
Emerging Markets Equity had $1,051 which expires in 2006; Global Equity had $356
which expires in 2006; Small Cap Growth had $923 which expires in 2004; $964
which expires in 2005 and $1,112 which expires in 2006; Mid Cap Value had $8,121
which expires in 2006; Small/Mid Cap CORE had $747 which expires in 2006; Short-
Term Bond had $131 which expires in 2006; Small Cap Value had $3,536 which
expires in 2006; and International Opportunities had $280 which expires in 2006.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
- -------------------------------------------------------------------------------
To the Contractowners, Policyholders and Trustees of
John Hancock Variable Series Trust I
 
  We have audited the accompanying statement of assets and liabilities,
including the schedules of investments, of John Hancock Variable Series Trust
I (the Fund) [comprising, respectively, the Large Cap Growth, Sovereign Bond,
Emerging Markets Equity, International Equity Index (formerly, International
Equities), Global Equity, Small Cap Growth, International Balanced, Mid Cap
Growth, Large Cap Value, Money Market, Mid Cap Value, Diversified Mid Cap
Growth (formerly, Special Opportunities), Bond Index, Small/Mid Cap Core, Real
Estate Equity, Growth & Income, Managed, Short-Term Bond (formerly, Short-Term
U.S. Government), Small Cap Value, International Opportunities, Equity Index,
High Yield Bond, and Strategic Bond Portfolios] as of December 31, 1998, and
the related statements of operations for the period then ended, and the
statements of changes in net assets and financial highlights for each of the
periods indicated therein. 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.
 
  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 and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 1998, by correspondence
with the custodian and brokers, or other appropriate auditing procedures where
replies from brokers were not received. 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 portfolios constituting John Hancock Variable Series
Trust I at December 31, 1998, the results of their operations for the period
then ended, and the changes in their net assets and financial highlights for
each of the periods indicated, in conformity with generally accepted
accounting principles.
