HOW TO USE THIS REPORT

For a quick overview of each
portfolio's performance during
the past year, refer to the
Highlights box. The letter from
the portfolio managers and
president provides a more
detailed analysis of the fund and
financial markets.

The charts alongside the letter
are useful because they provide
more information about your
investments. The top holdings
chart shows the types of
securities in which the
portfolios invest, and the pie
chart shows a breakdown of the
portfolios' assets by sector. The
portfolio changes show the
largest investment decisions your
portfolio manager has made over
the period in response to
changing market conditions.

The performance chart graphically
compares the portfolios' total
return performance with a
selected investment index.
Remember, however, that an index
may reflect the performance of
securities the portfolio may not
hold. Also, the index does not
deduct investment advisory fees
and other portfolio expenses,
whereas your portfolio does.
Individuals cannot buy an
unmanaged index fund without
incurring some charges and
expenses.

This report is just one of
several tools you can use to
learn more about your investment
in the Fortis Family of Products
and Services. Your investment
representative, who understands
your personal financial
situation, can best explain the
features of your investment and
how it's designed to help you
meet your financial goals.

FORTIS SERIES FUND, INC. ANNUAL REPORT,
DECEMBER 31, 1999

DEAR SHAREHOLDER:

The U.S. economy continued its robust expansion in 1999. For the year, GDP
advanced more than 4% fueled by strong consumer spending, particularly on
housing and related items and autos as well as corporate spending on technology
and telecommunications. Most impressively, this growth was achieved without
generating significantly higher inflation, which remained around 2% for the
year. During the year, the Federal Reserve did raise interest rates three times
in pre-emptive moves that were designed to fight emerging pressures from higher
oil, tobacco, and wage costs. Clearly, the decade-long trend of higher
productivity has been extremely important in mitigating these cost pressures.
Corporations were able to offset higher costs and earnings for the S&P 500 rose
approximately 18% for the year.

1999 was another extraordinary year for the stock market. The S&P 500 advanced
21.04%, the DJIA, 27.21%, the S&P Mid Cap Index, 14.70% and the Russell 2000,
21.36%. The year will also be remembered as the best IPO market on record. It
also was one of the most volatile years in recent history. All of the major
indices were down in the first and third quarters and up in the second and
fourth quarters. Investors periodically became concerned about inflationary
pressures that were then dampened with prompt Federal Reserve action.

The market's advance was extremely narrow. More that 70 of the stocks in the S&P
500 were down for the year by more than 10%. Clearly, the growth prospects for
many technology, communications, and small cap issues garnered the attention of
investors at the expense of all other sectors. In the final quarter of the year,
the market broadened to include many mid cap and small cap issues that had been
ignored in the previous year. Low valuations and the expectation for very strong
real growth finally were rewarded with renewed investor attention.

Our outlook for 2000 calls for continuing economic growth, albeit at a reduced
pace. We believe that the Federal Reserve will again tighten and that higher
interest rates will affect consumer spending as the year progresses.
Nevertheless, GDP is expected to advance 3.5% and corporate profits should rise
10-12%. The U.S. market will benefit in 2000 from improving economic growth in
both Europe and Asia. Given this outlook, we continue to believe that equities
should prove to be a rewarding investment this year although the gains may be
less spectacular than those experienced in 1999.

Last year the bond market experienced the second worst performance in the past
two decades (1994 had been the worst), turning in a negative total return (price
change plus income). Like 1994, the year began on the heels of a bond rally and
deteriorated in the process of Fed tightening. The Shearson Lehman
Government/Corporate Index produced a -2.15% return in 1999, with the longest
maturities suffering the greatest damage. Long Treasuries, as measured by the
Shearson Treasury 20+ Year Index, for example, produced -10.06% in total return.
All this despite a relatively low and stable rate of inflation. Monetary policy
was focused on "preemptive" action to head off possible inflationary pressure
from tight labor markets. Lip service was paid to the substantially favorable
impact of technology on productivity, but the Fed's actions reflect an
entrenched adherence to the tenet that dipping too far into the available supply
of employable labor will produce unwelcome upward pressure on open market
prices. This mindset on the part of the policy-setting Federal Open Market
Committee (FOMC) will continue during 2000, reinforced by the Chairman's
renomination and a slightly more conservative committee composition due to the
specific players involved in the annual rotation of the board. The problem is
that the Fed must enlist the aid of the financial markets to effectively slow
the momentum of growth. But, it must do so without pushing so hard as to produce
recessionary forces, particularly during an election year.

We believe that the market offers an unusually attractive opportunity for
investors to increase their bond holdings, rebalancing their portfolios
following a prolonged period of outperformance by equities. History provides
persuasive evidence that most bull markets in bonds begin before the Fed is
through tightening monetary policy and, therefore, before short term rates peak.
This year the potential for bonds is enhanced by the budget surplus and
associated reduction of Treasury bonds in the marketplace, particularly at the
long end of the maturity spectrum. Real interest rates (the difference between
the inflation rate and the yield of a bond) at around 4% (subtract 2.7% CPI from
6.74% yield presently offered by the 5-year Treasury note, for example) are
quite a bit higher than the historic average. This suggests the potential for
improved bond performance if, as we believe, the Fed is successful in heading
off a meaningful uptick in inflation. Yield spreads (the incremental yield above
comparable maturity Treasury securities) for non-government securities have
widened recently and offer superior performance potential through income
generation and price appreciation. This is particularly evident in high yield
bonds, where yields to maturity in excess of 10%, combined with the prospect of
price increases, can produce returns competitive with those historically
associated with the stock market. In short, we believe this to be an opportune
time to diversify portfolios by increasing your commitment to a variety of fixed
income investments.

Sincerely,

FORTIS SERIES FUND: MONEY MARKET SERIES

AS THE MOST CONSERVATIVE SUBACCOUNT, THIS PORTFOLIO IS DESIGNED FOR INVESTORS
SEEKING LIQUIDITY AND STABLE PRINCIPAL. ACCORDINGLY, THE MONEY MANAGERS CHOOSE
HIGH-QUALITY, SHORT-TERM SECURITIES.

U.S. financial markets have operated within very favorable economic conditions
for most of the last decade and should continue to do so in 2000. The U.S.
economy has been growing at a healthy 4% annual rate over the past four years
and is poised to grow nearly as fast next year. A year ago it appeared that the
economic problems of Asia, Russia and Latin America would slow the U.S.
expansion. By the spring of 1999, it became evident that many regions of the
world were recovering more quickly than expected and that domestic growth would
not slow. Throughout most of this period of exceptional growth, inflation had
been declining, but last year, higher oil prices caused inflation to rise
slightly. In response to growing inflationary pressures the Federal Reserve Bank
("the Fed") raised short-term rates 0.75% in a series of 0.25% moves. The hike
in short-term rates fully reversed the 0.75% cut in rates that the Fed had made
in late 1998 in reaction to global economic problems.

For the year ending December 31, 1999, the fund returned 4.96% compared to 5.32%
in 1998. Short-term rates were lower in 1999 because the Fed had lowered the
federal funds rate 0.75% in late 1998 and rates stayed at the lower levels until
the Fed began raising rates in the latter half of 1999. Rates are likely to move
even higher this year so we look for the fund's return to improve in 2000.

The fund continues to place great emphasis on high quality and liquidity, while
looking to target the fund's average maturity at an optimal length. Throughout
most of 1999 we targeted the fund's average maturity between 30 and 60 days. In
the first half of the year the average maturity of the fund remained near the
middle of that range. In late May, a combination of high levels of consumer
spending and tight labor markets led us to believe that the Fed would have to
raise rates to keep inflation in check. As a result we lowered the average
maturity to 35 days, where it remained until early September. At that time,
commercial paper issuers began to address their year-end funding needs much
earlier than normal due to their Y2K concerns. This phenomenon made the yields
on longer maturities very attractive. Although our outlook for short-term rates
did not change, we began lengthening the average maturity back to 60 days in
order to take advantage of the higher yields available on longer dated paper.
Feeling that short-term rates will continue to rise in the first half of 2000 we
returned to a 35-day average maturity by year-end.

OUTLOOK

Looking forward, we expect economic growth to moderate slightly over the next
year as the effects of higher rates take hold. As always, threats to the economy
(such as a stock market correction or rising inflation) still exist, however,
the probability of a significant slowdown appears quite remote right now. While
productivity gains and more intense competition have kept overall inflation low,
the strong job market and rising global demand have increased the odds that
inflation will rise in the coming year. The Fed's recent rate hikes were
intended to preemptively combat inflation and we feel that they will be
successful in doing so.

FORTIS SERIES FUND: U.S. GOVERNMENT SECURITIES SERIES

THIS PORTFOLIO IS DESIGNED FOR CONSERVATIVE INVESTORS SEEKING A STRONG TOTAL
RETURN, AS WELL AS A RELATIVELY HIGH LEVEL OF CURRENT INCOME. IT FOCUSES ITS
INVESTMENTS IN U.S. GOVERNMENT BONDS, TREASURIES AND GOVERNMENT AGENCY
MORTGAGE-BACKED SECURITIES.

The last year of the millennium was a difficult one for the Fixed Income
markets. Early 1999 saw a change in investor sentiment from easing expectations
to tightening fears. Concerns about emerging market contagion and a slowdown in
U.S. growth were replaced by strong economic data and concerns of potential
inflation increases. Strong job growth (1999 saw almost 2.7 million new jobs
created) and strong consumer spending (more than a 5% increase in 1999) combined
to help produce 4% real GDP growth for the year. This growth, coupled with a
rebound in the global economy and a rallying U.S. stock market raised concerns
at the Fed about the potential for inflation. During the course of the year, the
Fed made three tightening moves (June, August and November) which brought the
funds rate back to the 5.5% pre-crisis level of 1998. The bond yield drifted
higher and higher throughout the year. The low point in yield occurred in
January (5.07%) only to close the year yielding 6.48%. 1999 was the second worst
year in the bond market's history. The Federal Reserve's interest rate hikes
resulted in short-term rates moving up more in yield than did long-term rates.
The yield difference between the 30-year and 2 year Treasuries began the year at
56 basis points, only to end the year at 24 basis points.

We entered 1999 long to our benchmark with the expectation that economic growth
was going to slow. In early April we shortened our portfolio's duration from
107% to 100% of the benchmark, as we became concerned that economic growth was
going to be faster than we initially expected. In addition, in January we
increased our Mortgage Backed Security (MBS) exposure from a slight underweight
to a 10% overweight. We maintained the overweight for the balance of the year,
ending the year with a 12% overweight. The MBS overweight aided our performance
as MBS outperformed Treasuries by 1.28% in 1999. We also maintained an agency
debenture overweight during the year ending the year 8% overweight. This also
aided our performance slightly as agency debentures outperformed Treasuries by
0.22% during the calendar year. Unfortunately, the outperformance associated
with our MBS and Agency debenture overweights were not enough to offset the
sharp rise in interest rates and its impact on the fund. As a result, the
portfolio, which has a 4.75-year duration, produced a -1.94% total return,
compared to the Lehman Brothers Intermediate Government Index which has a
3.14-year duration and produced a +0.49% total return.

Going forward, we believe that economic growth will moderate from the 4% GDP
pace of last year. We also expect inflation to rise, although modestly. With
expectations that the Fed will further tighten monetary policy, in the short
term we expect to keep our duration either short or neutral to our benchmark. In
addition, tighter monetary policy and the Treasury's recently announced plans to
repurchase longer maturity debt suggests to us that yield curve could invert
temporarily, with shorter maturities yielding more than longer maturities.
Finally, we believe that the incremental yield that both MBS and agency
debentures offer versus Treasuries continues to justify an overweight position.

PORTFOLIO WILL PURSUE HIGH-QUALITY CORPORATE BONDS AND U.S. GOVERNMENT
SECURITIES. A PORTION MAY BE INVESTED IN DIVIDEND-PAYING STOCKS AND LOWER-RATED
CORPORATE BONDS FOR ADDED OPPORTUNITY.

1999 was the second worst year ever for the bond market. Fueled by recovering
global economies, rising commodity prices, tightening labor markets, and soaring
foreign and domestic equity markets, interest rates rose 1.5% on average over
the year. Faced with 4% real growth in the economy's 9th year of expansion, the
Federal Reserve Board reversed it 1998 interest rate cuts, raising the Federal
Funds rate 0.75% in three separate moves during the second half of the year. In
addition, the Fed shifted to a tightening bias at the December Federal Open
Market Committee (FOMC) meeting, effectively admitting that only its concerns
about Y2K prevented it from raising short rates again in 1999.

The market for non-Treasury securities exhibited uneven performance during 1999.
During the first quarter, yield premiums fell sharply as the fears of the 1998
global crisis diminished and liquidity returned to the markets. During the
second and third quarters, corporate bonds gave most of the first quarter's
performance back, as high levels of issuance ahead of year-end, pushed yield
premiums (spreads) almost as high as they were during 1998. This was partially
reversed in the fourth quarter, once again driven by a lack of supply in the
market, as well as the realization that disruptions associated with Y2K would
not be as severe as originally thought.

We began the year with a positive outlook on interest rates, believing that
1998's financial crisis would translate into slower growth both domestically and
abroad. Early in the second quarter, however, evidence of the global recovery
materialized, and we became convinced that the Fed would ultimately be forced to
raise short term interest rates in order to slow the pace of the domestic
economy. We then shortened the portfolio's duration to neutral versus its
benchmark, and, with the exception of several short term tactical moves during
the year, we have remained neutral since then. With respect to non-Treasury
assets, we reduced our exposure early in the second quarter, but then took
advantage of the supply related widening in spreads over the summer to increase
our exposure to Corporate Investment Grade, and Below Investment Grade
securities. We believe that the spreads in these sectors are more reflective of
short-term supply/demand imbalances than the fundamentals. As a result, they
offer long term value. For the year, the fund's return was -1.68% compared to a
- -2.15% for the Lehman Government Corporate Index and -0.82% for the Lehman
Aggregate Index.

OUTLOOK

We expect that the rise in rates in the second half of 1999, coupled with the
Fed tightening we expect in the first quarter of 2000 will slow the economy down
to a more tolerable 3-3.5% growth rate for the year. We also anticipate that
inflation will pick up modestly from its current 2.1% (Core Year-Over-Year CPI
as of 11/99), but not pose a serious threat to the overall level of interest
rates. This combination of slower growth and continued tame inflation data will
ultimately lead to lower bond yields and lower yield premiums for non-Treasury
securities in the next 12 months. Finally, we wouldn't be surprised to see
yields on shorter maturity Treasuries exceed those of longer maturity
Treasuries. With the market anticipating up to an additional one percent
increase in the Federal Funds rate this year, and the Treasury expected to
shorten the average maturity of its outstanding debt through a buyback program,
the supply/demand dynamics favor long term interest rates.

FORTIS SERIES FUND: GLOBAL BOND SERIES
(SUBADVISED BY MERCURY ASSET MANAGEMENT)

BECAUSE IT OFFERS INVESTORS A COMBINATION OF CURRENT INCOME AND GROWTH
POTENTIAL, THIS PORTFOLIO MAKES AN EXCELLENT CHOICE FOR THOSE INVESTORS WHO SEEK
TO ROUND OUT THEIR INVESTMENT SELECTIONS WITH GLOBAL BONDS. THE MONEY MANAGERS
SEEK OUT HIGH-QUALITY BONDS AND OTHER FIXED INCOME SECURITIES OFFERED BY
GOVERNMENTS AND CORPORATIONS WORLDWIDE, EMPHASIZING DEVELOPED COUNTRIES.

The Fortis Series Global Bond Series returned -7.53% in 1999, compared to its
benchmark the Salomon Brothers Global Bond Index, which returned -4.27%. The
negative performance of the Series and the index occurred against a backdrop of
over one hundred-interest rate decreases across the globe from October 1998 to
October 1999. This was an effort by the international community to buoy
financial markets and provide a cushion for lending across borders. In the fall
of 1999, the Federal Reserve Board changed directions by raising interest rates
in an effort to head off perceived inflationary signs.

The fund is currently overweight in U.S. and German bonds, relative to the
index. Given the rising interest rate environment in both countries throughout
1999 and coupled with the fund's underweight in Japanese bonds-which rallied in
December as supply concerns subsided and deflation persisted. The Series
underperformed its benchmark.

On March 13, 2000, this Series will become the Multisector Bond Series and will
be subadvised by AIM Advisors, Inc. Under prior management the Series invested
primarily in high-quality U.S. and foreign government and corporate fixed-income
securities. Under AIM's management the Series will invest primarily in
investment-grade corporate bonds and U.S. government securities. In addition,
the Series will be able to invest up to 40% in foreign bonds, both government
and corporate, and up to 35% in non-investment grade "high yield" bonds. This
increased flexibility should provide more opportunity for the Series to perform
well.

FORTIS SERIES FUND: HIGH YIELD SERIES

LONG-TERM INVESTORS, WILLING TO ACCEPT GREATER PRICE FLUCTUATIONS, MAY CHOOSE TO
DIVERSIFY THEIR STOCK OR BOND INVESTMENTS WITH THIS PORTFOLIO OF HIGHER YIELD
BONDS. ITS MONEY MANAGERS INVEST IN A WIDELY DIVERSIFIED PORTFOLIO OF
LOWER-RATED CORPORATE BONDS.

The twelve-month period ended December 31, 1999, was a period of healing for the
U.S. financial markets; including the high yield bond market. The year began in
the aftermath of a global financial crisis, which had prompted the Federal
Reserve to add liquidity to the financial system and cut the Federal Funds rate
three times in rapid succession in late 1998. These emergency measures helped
stabilize the high yield market early in 1999, and set the stage for a potential
recovery to more normal levels. However, attempts by the bond market to move
higher were short-lived as the Federal Reserve reversed course and took back the
interest rate cuts once investor confidence had been restored and a global
recovery appeared underway. Despite the significant increase in interest rates
that occurred during 1999, the Fund managed to return 1.17%, compared to the
return for the Lehman Brothers High Yield Index of 2.39%.

During the first half of the year, the high yield market benefited from an
improved outlook for corporate earnings and contained expectations regarding
future inflation. However, rising interest rates and reduced investor demand for
fixed income products dampened an early rally, leaving the high yield market
with a modest 2.96% gain for the first half of 1999, according to Chase
Securities, Inc.

By the second half of 1999, corporate issuers and investors alike began to focus
on calendar year-end and the potential implications of "Y2K". Corporations
sought to provide for year-end funding needs in advance, creating a temporary
bulge in supply, while investors sought incremental safety and security in their
investment portfolios. The downward pressure exerted by these trends caused a
decline in high yield bond prices, which offset the interest income earned
during the period. The net effect was a flat second half for the high yield
market.

For the year 1999, the fund's performance was enhanced by its heavy exposure to
top-performing sectors such as cable, communications and media. The fund's
performance was held back by its conservative investment posture which kept it
from fully participating in the market rally early in the year. The fund was
also hurt, along with most of the high yield market, by our holdings in higher
quality, interest rate sensitive bonds, which tend to under-perform when
interest rates move higher.

In July of this year, a new portfolio manager, Ken Peterson, was added to the
fund. Mr. Peterson brings extensive knowledge and experience managing high yield
portfolios accumulated during his 14-year investment career. The strategy he
employs is to couple a disciplined top-down approach with intensive-bottom up
analysis to deliver optimal investment returns.

OUTLOOK

For the coming year, we expect the US economy to decelerate, in part due to the
drag on the economy caused by higher intermediate interest rates. While the
economy is strong and resilient, the labor markets are tight, natural resource
prices are firming and wages are creeping upward. This will likely cause the
Federal Reserve to raise rates, moderately slowing the economy but preventing
excesses from building up in the nation's economic and financial systems. Our
fund is well positioned for such an environment with a higher relative quality
bias and a focus on industry sectors that tend to generate stable cash flows. At
today's valuation levels, we feel the high yield market represents good
fundamental value and offers investors the potential for attractive returns.

FORTIS SERIES FUND: GLOBAL ASSET ALLOCATION SERIES
(SUBADVISED BY MORGAN STANLEY ASSET MANAGEMENT)

DESIGNED ESPECIALLY FOR INVESTORS WHO WANT A FLEXIBLE PORTFOLIO THAT SEEKS TOTAL
RETURN FROM A BLEND OF GROWTH POTENTIAL AND CURRENT INCOME FROM AROUND THE
WORLD, INCLUDING THE UNITED STATES. THE PORTFOLIO MANAGERS INVEST IN GLOBAL
STOCKS, BONDS AND MONEY MARKET INSTRUMENTS IN PERCENTAGES THAT MAY VARY WITH
MARKET CONDITIONS.
PERFORMANCE
During 1999, the portfolio produced an extremely disappointing performance,
returning -0.87% for the period compared to a return of 13.18% for the benchmark
of 60% MSCI World Index / 40% JPM Global Bond Index. In terms of asset
allocation, the portfolio remained close to its benchmark weighting and this
therefore did not make a large contribution to performance.

The global equity portion significantly underperformed its benchmark, producing
a return of 4.62% versus 25.34% for the MSCI Index. Importantly over 13% of this
discrepancy in performance came in the final quarter of the year when
performance was seriously constrained by our lack of exposure to the phenomenal
performance of certain mega cap technology firms. The strong performance of the
World Index masked divergent sectoral performance. For example, the best
performing sector of the World Index, information technology, rose 228% last
year while the worst, the defensive Consumer Staples group, actually fell 7%.
Combining our severe underweight to information technology and our significant
overweight to consumer staples explained roughly 70% of our underperformance in
the fourth quarter and for the year.

The global fixed income portion of the portfolio also underperformed but by a
smaller degree; the portfolio producing a return of -6.66% compared to a
benchmark return of -5.07%. While rising yields caused the portfolio to return a
small negative return in local currency terms, this translated into more
significant negative returns when measured in U.S. dollars due to the weakness
of the European currencies. In terms of relative performance, our long duration
exposure to the dollar bloc and European markets and our short duration exposure
to the Japanese market were negative factors. Also subtracting from performance
was our underweighting to the yen and our underweight exposure to the long end
of the UK market. More positively, our exposure to the credit sector enhanced
performance.
STRATEGY
The structure of the equity portion reflected our bottom up stock selection
style. There was little change in the broad geographical structure of the equity
portion over the period. We remained significantly underweight in the US,
slightly underweight in Japan and overweight in the European markets. In terms
of sectors, we have retained an overweight exposure to the more defensive
sectors, for example consumer staples and utilities, and also those sectors
which we feel should outperform in line with an expanding global economy, such
as building materials.

The global fixed income portion remained long duration in the dollar bloc and
European markets and short duration in the Japanese market. In terms of sector
positioning, the fund retained an overweight exposure to the credit sector.
Activity within the fund throughout the year was reasonably low. Within Europe,
we added exposure to the Danish bond market and in the UK, cut all exposure to
longer than 5-years adding duration to the euro market. In terms of currency
positioning, the fund remained underweight in the Japanese yen versus the US
dollar and the European currencies although this was shifted more in favour of
the European currencies in December. The portfolio also continued to increase
exposure to the credit sector throughout the year.
OUTLOOK -- GLOBAL EQUITY
We see the "technology" bubble as the biggest risk in the global equity market
following December's huge run. The portfolio's value discipline has precluded us
from participating in this bubble. The technology sector trades at 91 times cash
flow whilst the MSCI World Index trades at 18 times cash flow. The portfolio
owns little in the way of technology or other mega-cap companies that have
dominated equity market returns in the last two years. Instead, we have
concentrated on undervalued companies in the "old economy" such as financials,
food, beverages, tobacco and utilities. While these sectors have underperformed
in 1999, they are now extremely cheap relative to the excesses within the
technology area, where investor behavior remains exceptionally fickle, witness
Lucent, down 34% over the past two weeks.

The extreme polarization of the markets continues to create opportunities to buy
good businesses at great prices while the disparity between new Japan and old
Japan has now grown so large that we are also finding suitable risk reward
tradeoffs among the third tier restructuring stories.

Despite the difficulties that have faced value investors over the past two
years, we expect the portfolio to perform defensively relative to the index in a
weak overall market should interest rates continue to rise. Likewise, we expect
our overweighting to Europe and underweighting to the US to bear fruit this year
given Europe's improving fundamentals and more attractive relative valuation.
Implicit in today's "new economy" valuations are massive expectations for
growth. As the market is paying a lot for the promise of future cash flows these
"new economy" stocks should also be more vulnerable to higher interest rates
(just like long duration bonds) although, somewhat surprisingly, the market has
chosen to ignore this relationship for now.
OUTLOOK -- GLOBAL FIXED INCOME
The outlook for the global economy continues to improve and over the next year,
we expect activity between the regions to be more closely synchronised. In the
euro-zone, low real interest rates and an undervalued currency should continue
to support the broadening recovery while in Japan, the economy will continue to
benefit, at least in the short term, from ongoing fiscal stimulus. Meanwhile in
the U.S., we expect tighter monetary conditions to lead to some slowdown in
domestic demand growth and activity to moderate from its current 4% pace.

We believe the rise in yields in the dollar bloc and European markets over the
past year reflects this strong growth outlook as being already discounted by the
bond markets, and that it is inflation that holds the key to bond market
performance in 2000. We expect that in the absence of significantly higher
inflation, the potential for a further rise in yields will be limited, and as a
result, we retain our modestly positive view for this year.

In terms of currency positioning, we believe that growth and interest rate
differentials will continue to disadvantage the Japanese yen and we retain our
bearish stance. At current levels, the yen real exchange rate is close to a
10-year high versus the euro and as such we view the yen as being particularly
overvalued relative to the euro. We have therefore shifted our yen
underweighting in favour of the euro and euro-linked currencies which we expect
to recover over the near or medium term in line with a stronger European
economy.

FORTIS SERIES FUND: ASSET ALLOCATION SERIES

DESIGNED FOR INVESTORS WHO SEEK TOTAL RETURN FROM A BLEND OF GROWTH POTENTIAL
AND CURRENT INCOME. THE PORTFOLIO MANAGERS SELECT A MIX OF U.S. STOCKS, BONDS
AND MONEY MARKET INSTRUMENTS IN PERCENTAGES THAT MAY VARY WITH CURRENT MARKET
CONDITIONS.

1999 proved to be another stellar year for the equity market as a combination of
strong earnings growth and low inflation ignited investor appetite for stocks.
Higher valuation levels on higher earnings are a potent combination for stock
prices. The fixed income markets, however, faced three consecutive rate
increases by the Federal Reserve as concerns over inflationary prospects
surfaced. An investment environment such as this past year underlines the
advantage of an asset allocation fund.

For the year ended December 31, 1999, the Asset Allocation Series returned
19.56% this compares to a gain of 21.04% for the S&P 500 and a decline of -0.82%
for the Lehman Brothers Aggregate Bond Index.

The asset allocation between stocks and bonds was targeted at a neutral 65%
stocks, 35% bonds at year-end. This ratio had been reduced by the Asset
Allocation Committee in late summer to 60% equities, and then increased in
November back to 65%. In the equity area, telecommunications and service sectors
are overweighted versus the market while basic materials and consumer-related
sectors have been underweighted. Telecommunication and technology holdings
contributed to performance while energy and financial holdings generally
detracted from overall performance.

In the fixed income portion of the fund, we shortened the portfolio's duration
to the benchmark early in the second quarter when we became convinced that
domestic growth was not as severely impacted by the 1998 global crisis as we had
anticipated, and that the 1998 interest rate cuts would be ultimately reversed.
In fact, the Federal Reserve did reverse those 0.75% cuts over the second half
of the year while we maintained a neutral duration in the portfolio. As for the
composition of the fixed income portion, we took advantage of a supply-driven
widening of corporate yield spreads to increase our exposure to corporate
investment grade and below investment grade securities. We believed the widening
will be reversed early next year and offer a good relative value compared to
government securities.

The capital markets face the prospect of rising interest rates by the Federal
Reserve as the economy continues its robust expansion. While earnings prospects
remain bright, rising interest rates could affect the valuation levels of
equities, which are near historic highs. In the equity area, we continue to
focus on companies with solid growth prospects at relatively attractive
valuation levels, and hence our neutral equity weighting.

The combination of slower growth and continued controlled inflation should
ultimately lead to a better overall interest rate environment and lower yield
premiums for non-Treasury securities over the next 12 months.

FORTIS SERIES FUND: VALUE SERIES

DESIGNED FOR INVESTORS WHO PREFER TO INVEST IN EQUITY OPPORTUNITIES AT
ATTRACTIVE VALUATIONS. THE PORTFOLIO MANAGERS CHOOSE STOCKS WITH CURRENT PRICES
THAT DO NOT NECESSARILY REFLECT THE STOCK'S POTENTIAL VALUE.

For the year ended December 31, 1999, the S&P Barra Value Index returned 12.72%
while the Fortis Value Series returned 8.96%. The portfolio underperformed the
index due to holding more smaller capitalization companies than the index.

The portfolio's primary strategy is to invest in undervalued companies with
accelerating growth, where we anticipate a company's growth rate to rise over
time. To the extent that we cannot find undervalued companies with accelerating
earnings, we focus on our secondary criteria, inexpensively valued growth. We
continue to maintain adequate diversification across market sectors and remain
focused on stock selection.

Apple Computer, Columbia/HCA Healthcare, USA Networks and Liberty Media Group
were among the portfolio's better performing stocks during the past year.
Recently we have added a substantial position in oilfield services. We believe
that the oilfield services stocks have excellent opportunities for earnings
acceleration in the coming months due to the high price of oil. Their customer,
the oil industry, now finds it profitable to drill for oil after a prolonged
spell of relatively low oil prices. To fund our new position in oilfield
services stocks we have sold many of our international integrated oil companies.
While those companies have been enjoying substantial acceleration in earnings
growth over the past several months, it will become much more difficult for them
to sustain their recent growth into the future if only because the
year-over-year comparisons will become so much more difficult.

Looking ahead, we see the economy continuing to expand but at a slower rate. In
this environment we believe that the health care sector is a logical place for
us to invest because companies in the business of providing goods and services
used in the delivery of health care tend to enjoy relatively stable demand. We
are maintaining a below-average exposure to financial stocks because we believe
that the business environment will become more challenging for them in the
coming years. Rising interest rates or slowing global growth could negatively
affect the portfolio's performance. We continue to monitor the effects of
interest rates and the economy on the portfolio's holdings.

We remain focused on investing in undervalued companies with accelerating growth
or inexpensively valued growth. We believe that this investment philosophy will
provide good returns to shareholders for the long term.

FORTIS SERIES FUND: GROWTH & INCOME SERIES

THIS PORTFOLIO OFFERS A SOLUTION TO INVESTORS WHO WANT TO COMBINE CONSERVATIVE
GROWTH OPPORTUNITIES WITH INCOME POTENTIAL. IT FOCUSES ON COMPANIES WITH
ATTRACTIVE DIVIDEND GROWTH PROSPECTS RELATIVE TO THE STANDARD AND POOR'S 500
STOCK INDEX. THE PORTFOLIO IS WELL DIVERSIFIED WITH EXPOSURE TO MANY SECTORS OF
THE ECONOMY.

The year 1999 proved to be another stellar year for equities as the market
embraced the strong earnings growth stemming from the robust economy. Inflation
remained benign which enabled valuations to expand on top of the higher level of
earnings. Economic recovery in international markets added to the positive
environment for the equity market. Fearful of a revival of inflation, the
Federal Reserve boosted interest rates three times during the year, which caused
some momentary bumpiness but did not derail the bull market.

For the full year of 1999, the Growth & Income portfolio posted an increase of
10.72%. This compares to a greater gain of 21.04% for the S&P 500. This
portfolio is generally less volatile than the S&P 500 and also produces a
current yield above the S&P 500. The technology sector performed particularly
well in 1999, a factor which hurt comparative performance. Technology stocks
generally pay little or no dividends and as a result, this sector was
significantly underweighted in the portfolio. The service and telecommunications
sectors were overweighted and contributed to performance results. The energy and
financial sectors were overweighted for most of the period but were both reduced
to below market weights by year-end.

The capital markets currently face the prospects of further Federal Reserve
tightening in the form of rate increases early in the new year. While the
economy remains robust and earnings prospects bright, higher interest rates will
likely cause some consolidation in the equity market after its recent strength.
Going forward, the investment approach for Growth & Income is being shifted
somewhat to a greater emphasis on growth versus current income. As a result,
technology issues held will likely rise as a percentage of assets. In this
period of high valuation and rising interest rates, great attention is being
paid to growth prospects and relative valuations.

FORTIS SERIES FUND: S&P 500 INDEX SERIES
(SUBADVISED BY DREYFUS)

THIS PORTFOLIO IS DESIGNED ESPECIALLY FOR INVESTORS WHO WANT TO EMULATE THE
TOTAL RETURN OF THE STANDARD & POOR'S 500 INDEX.

The fund closely tracked the return of the S&P 500 Index for both the quarter
and the year ended December 31, 1999. The fund returned 20.34% versus 21.04% for
the S&P 500 Index. The primary difference between the fund's performance and the
index's return is the effect of fund expenses.

The Series S&P 500 Index is designed to passively replicate the large
capitalization U.S. equity market as represented by the S&P 500 Index. The
portfolio uses a strategy of full replication, which entails holding all stocks
in the S&P 500 in direct proportion to their weight in the index. S&P 500
futures are utilized to efficiently manage daily cash flows.

The S&P 500 Index had a positive return for the year ended December 31, 1999,
outperforming both the S&P 400 Mid Cap Index and the S&P 600 Small Cap Index.
Stocks of electronics firms, communication equipment firms and aluminum
companies were among the best performing industries in the S&P 500. Among the
index's worst performing industries were tobacco firms and office equipment
companies.

FORTIS SERIES FUND: BLUE CHIP STOCK SERIES
(SUBADVISED BY T. ROWE PRICE)

THE MONEY MANAGERS FOR THIS PORTFOLIO TARGET "BLUE CHIP" COMPANIES WITH LEADING
MARKET POSITIONS, SEASONED MANAGEMENT AND STRONG FINANCIAL FUNDAMENTALS. IT IS
DESIGNED FOR PEOPLE WHO WANT TO INVEST IN WELL-ESTABLISHED COMPANIES THAT
GENERATE CONSISTENT, DURABLE EARNINGS GROWTH WITH THE POTENTIAL FOR ABOVE
AVERAGE STOCK PERFORMANCE.

MARKET ENVIRONMENT

During the period, U.S. corporations benefited from strong GDP growth, low
inflation, and improvement in international economies. Markets rallied around a
belief that technology, telecommunications, and the Internet would enhance
growth while limiting inflation. These developments added fuel to the bull
market in U.S. equities, but the threat of inflation and three Federal Reserve
interest rate hikes caused occasional volatility. Investors favored rapidly
growing cyclical and technology firms, while the stocks of steady growth
companies and interest rate-sensitive stocks struggled. In other areas, such as
the retail and energy sectors, many stocks performed well but were overshadowed
by gains in technology.

PORTFOLIO REVIEW

In this volatile but favorable environment, the portfolio produced solid
results. However, performance was muted somewhat because we generally hold fewer
cyclical, technology, and foreign stocks than some peers. Pharmaceuticals and
financials, two large sectors in this fund, posted more moderate performance.
Overall the portfolio produced a return of 19.88% versus the S&P 500 Index
return of 21.04%

Although the portfolio had less technology exposure than the average growth
fund, several tech holdings performed well. Among them, Microsoft was our best
performer for the year, followed by Oracle, America Online, and Sun
Microsystems. Limited investments directly in Internet companies generated
strong returns. Telecommunication stocks, including Corning and Nokia, were
valuable contributors to performance. Entertainment and media companies also did
well, as did several selected retailers, such as Wal-Mart and Home Depot.

On the other hand, several financial stocks weakened on rising interest rates,
while a number of holdings in supermarket chains and drugstores struggled
against Internet competition. Two holdings -- Waste Management and in the last
six months Tyco International -- did very poorly as investors questioned their
financials. We eliminated all but a minor portion of Waste Management, but we
think a SEC inquiry will not reveal major problems at Tyco, and maintain a
healthy position in the stock.

OUTLOOK

On balance, we believe that inflation and interest rates will increase but at a
manageable pace and corporate earnings among blue chips should remain strong.
Even so, we continue to recognize that almost all stocks are expensive by most
conventional measures, and more market volatility seems certain. Thus, careful
stock selection with a focus on valuation and sustainable growth should become
increasingly important.

FORTIS SERIES FUND: INTERNATIONAL STOCK SERIES
(SUBADVISED BY LAZARD FRERES ASSET MANAGEMENT)

INVESTORS WILLING TO BALANCE THE RISKS AND REWARDS OF INTERNATIONAL STOCK
INVESTING OFTEN SELECT THIS PORTFOLIO TO DIVERSIFY AN ESTABLISHED INVESTMENT
STRATEGY. IT FOCUSES EXCLUSIVELY ON GROWTH COMPANY STOCKS OUTSIDE OF THE UNITED
STATES.

Despite considerable volatility, the MSCI EAFE Index ended the year up
approximately 27.30%. The Japanese equity market soared 60% as companies
continued reforms and the local economy began to show signs of recovery after a
decade of disappointment. Despite the weakness of the new euro, Europe also
posted solid gains as a wave of hostile bids and a growing equity culture pushed
markets 16% higher. The International Stock portfolio ended with a strong fourth
quarter and ended 1999 up 23.99% slightly trailing the MSCI EAFE Index.

The technology sector outperformed all other sectors in the S&P 500 Index. The
convergence of telecommunications and technology has not only reduced
interaction costs, but has broken down geographic and industry barriers to
facilitate a truly global economy. The pervasiveness of technology in business
and society was demonstrated this year by fears of the ramifications of a Y2K
software glitch. Although Y2K fears subsided, technology's incorporation in
business and accelerating IT spending highlighted continued growth potential.
Investors latched onto these themes to drive technology stocks and wireless
telecommunications stocks to exorbitant levels. Nokia was perfectly positioned
at the nexus of mobile communications and technology and its stock soared to
become the largest company in the MSCI EAFE Index. However, Nokia now trades at
a price to cash flow that is nearly impossible to defend on a fundamental basis.
Mergers and acquisitions compounded the extreme valuations and performance as
companies such as Vodafone used its highly valued stock to make the world's
largest ever hostile bid for the already expensive Mannnesmann. This performance
trend by technology and related companies accelerated in the fourth quarter and
even more acutely in December, which led the International Stock portfolio to
lose relative performance late in 1999.

The portfolio realized significant value in the technology sector through
investments in relatively less expensive companies. Telefonica and Portugal
Telecom both benefited tremendously from well-received IPO's. Alcatel made
several acquisitions to bolster its data networking equipment capabilities and
its stock price reacted favorably. But the best performer by far was NTT Mobile
Communications. The leading Japanese wireless communications company soared in
1999 on the back of the success of "i-mode", the first widely used WAP mobile
phone. The portfolio is benefiting from investments in companies not
traditionally linked to technology. Philips Electronics and Siemens are
transforming into technology-focused businesses.

The portfolio's investment style led us to invest in companies with strong
global brands. Valuations of many branded companies are now at historic lows,
yet their financial productivity remains outstanding. Although these moves hurt
relative performance this year, we are comfortable with the outlook for
companies such as Cadbury-Schweppes, Heineken, Diageo, and Unilever, given their
strong track record and return versus valuation characteristics. Combining
internally driven improvements with the potential for external growth if
emerging markets continue to rebound, branded companies are unlikely to remain
out of favor too much longer.

Dramatic change took place in the banking sector during 1999. Fuji Bank,
Industrial Bank of Japan (IBJ), and Dai-ichi Kangyo will create a single holding
company to form the world's largest bank with assets of $1.3 trillion.
Management hopes to form a "national champion" with sufficient size and power to
compete against American and European rivals. The ripple effect of the merger
led to further banking and insurance consolidation by year-end. In Europe,
Banque Nationale de Paris (BNP) tried to form a French banking powerhouse with a
combined hostile bid for both Societe Generale and Paribas. To date, most
banking consolidation has taken place within country borders where the greatest
cost savings exist. As banks reach sufficient domestic scale, we expect
cross-border mergers to accelerate as we have witnessed in numerous industries.

With this year's advent of the European Monetary Union (EMU) and Y2K concerns,
corporate change continued to accelerate on a global basis. The frenzied pace of
mergers and acquisitions topped $3.3 trillion worldwide, while restructuring,
disposals and spinoffs showed no signs of slowing. These corporate actions to
improve financial productivity and strategic positioning in a world of
heightening global competition remained the most enduring performance driver in
1999.

FORTIS SERIES FUND: MID CAP STOCK SERIES
(SUBADVISED BY DREYFUS)

THIS PORTFOLIO IS DESIGNED FOR INVESTORS WHO WISH TO INVEST IN MID
CAPITALIZATION COMPANIES THAT HAVE EXCELLENT POTENTIAL GROWTH CHARACTERISTICS
BUT ARE REASONABLY PRICED.

PERFORMANCE REVIEW

For the year ended December 31, 1999, the performance of the Mid Cap Stock
portfolio was 10.97%, which was below the S&P Mid Cap 400 Index return of
14.70%. While the absolute return in the 4th quarter was 14.76%, we are
nonetheless disappointed that we did not exceed the performance benchmark during
the period under review.

The quantitative process that we use in managing this portfolio performed below
its historical trend throughout 1999. Our valuation process uses a number of
fundamental characteristics that are both price (value) and earnings (growth)
sensitive, while in portfolio construction we follow a sector neutral approach.
We feel that during most of 1999 we operated in a market environment where
investors paid little attention to traditional measures of value such as price,
price/earnings, and actual earnings growth.

Companies with the highest price multiples and in many cases very modest real
earnings provided the most attractive returns during 1999. Our process uses long
term trends to guide our stock selections, and thus we continued to operate with
some sensitivity to issues such as actual earnings. This process did not
preclude us from owning any of these types of issues, and in fact we owned a
number of holdings that had total returns during the 4th quarter of over 50%.
These issues include Verisign +258.6%, Medimmune +66.4%, Young & Rubicam +60.9%,
and Legato Systems +57.8%. 1999 was also an equity market environment where we
saw a concentration of performance in certain sectors (technology). According to
our calculation, if one looks at the make-up of the S&P Mid Cap 400 Index at
year-end, over 60% of those companies had a negative return for 1999. Thus, both
our valuation process and portfolio construction techniques were subject to less
than favorable market conditions.

INVESTMENT PROCESS

Dreyfus employs its disciplined investment process in the management of the Mid
Cap Stock Series. The portfolio is constructed in line with our mid cap strategy
which seeks to outperform the S&P 400 Mid Cap Index through stock selection
while closely managing the portfolio's risk characteristics versus the
benchmark. Dreyfus' stock selection involves a dynamic valuation process using
15 broad based fundamental factors. These include both earnings (growth like)
oriented and price (value like) oriented factors which are dynamically weighted
to capture the characteristics the market prefers in the current environment.
Stocks are selected based upon their exposures to the characteristics that are
preferred. As of December 31, the process had a moderate emphasis on price
oriented characteristics.

PORTFOLIO CHARACTERISTICS

Portfolio construction seeks to maximize our stock selection capabilities
through carefully neutralizing risks that we believe are not rewarded. The beta
of the portfolio is managed very close to the benchmark in an attempt to
neutralize market risk. The economic sectors are managed in line with the S&P
400 Mid Cap Index to protect against unintended industry bets. BARRA risk tools
help us determine other factors driving portfolio risk, and we manage these risk
factors versus the benchmark. The portfolio held 147 names, broadly diversified
across all economic sectors.

FORTIS SERIES FUND: SMALL CAP VALUE SERIES
(SUBADVISED BY BERGER)

THIS PORTFOLIO IS DESIGNED FOR AGGRESSIVE INVESTORS WHO WANT TO INVEST IN SMALL
COMPANY STOCKS THAT THE PORTFOLIO MANAGERS BELIEVE ARE SIGNIFICANTLY
"UNDERVALUED".

For the year ended December 31, 1999, the portfolio had a return of 15.34%
versus a return of 21.36% for the Russell 2000 Index. The portfolio benefited
from the announced mergers of Pittway and Jostens for premiums of 50% and 25%,
respectively. We feel that mergers will continue to increase as corporate
America recognizes the opportunity creates by the two-tier market and resulting
historic low valuations.

During the fourth quarter of 1999 and over the entire year, our strongest
performance came from our fallen growth stocks. Growth companies can become
value situations when they sell at depressed prices relative to their secular
growth. These companies are exceedingly strong financially and are showing
confidence in their future by buying their own stock. Specifically, the
portfolio has accumulated positions in information technology staffing companies
that declined over 70% from their highs due to near-term earnings concerns about
their transition from Y2K solutions to e-commerce strategies.

We are particularly encouraged that our gain for the year was accomplished in
spite of an overweighting in the weakest market sector, financials. There are
clear signs of strength in this sector. Bank and thrift earnings were up 8%-10%
in 1999, and are expected to be up as much in 2000. There have been aggressive
stock buy backs and dividend increases. Consolidation continues and is expected
to accelerate in 2000.

In the REIT industry, there were cash flow gains of 10%-20% in 1999 and those
are expected to grow 10% in 2000. After the 12% decline in the group, dividend
yields are now in the 8%-10% range, significantly higher than the 6.5% return on
10-year Treasuries. (REIT returns tend to be on par with Treasuries.) These
extremely attractive values give us confidence in the future risk reward ratio
of our portfolio.

The last three months of 1999 saw a continuation of the underperformance of the
small cap value sector compared to the broader market. While we await the return
of capital into the small cap arena, we will pursue our value discipline and
position the portfolio to take advantage of the market's currently elusive, but
we believe ultimately inevitable recognition of value.

FORTIS SERIES FUND: GLOBAL GROWTH SERIES

GROWTH INVESTORS WHO WANT TO DIVERSIFY AND EXPAND THEIR HORIZONS BEYOND THE
UNITED STATES MAY WANT TO CONSIDER THIS DIVERSIFIED PORTFOLIO.

During the twelve month period ended December 31, 1999, the Global Growth Series
portfolio returned 57.68%. Over the same period, the Morgan Stanley Capital
International World Index returned 25.34%. The majority of the gains occurred in
the second half of 1999 when the world equity markets increased their focus on
companies with strong growth prospects, particularly those involved in
technology products and services. The Global Growth Series portfolio has
historically invested in companies with above average earnings growth anywhere
in the world, including the United States. The portfolio's overweight exposure
to growth-oriented companies in Japan also played a contributing factor in the
strong relative outperformance.

The outlook for the world's economy has improved quite dramatically relative to
a year ago. We are presently in a synchronized global economic recovery.
Countries which have been in recessions over the past several years such as
Japan, Germany, France, and Korea are now demonstrating economic growth. This
represents the first time since 1994 when all of the world's major economies
were demonstrating positive growth. The outlook for the world's equity market
has also improved dramatically since one year ago. Many U.S. based companies are
benefiting from worldwide demand for products utilizing the latest technologies.
An improved global economy will result in strong demand for technology based
capital equipment. Areas such as wireless telephones, broadband cable systems,
high speed internet access, and telecommunications systems will prosper in the
"new global economy". Factors influencing overseas holdings will be the
continuation of the trend towards corporate restructurings. There are
significant changes taking place in Japan which deal with cultural and
management issues at major Japanese corporations. This renewed focus on cost
cutting and increasing earnings growth will be a positive for investors in those
companies. The other major change is the emergence of the "new economy" in
Japan. Companies involved in business services and internet technology are
beginning to make inroads in the corporate landscape. The major uncertainty
looking forward will be what impact the synchronized global recovery has on
inflation. In recent years, the recession in Asia and Japan has helped keep
global prices for commodities and consumer goods at low levels. With an
improving global economy, it is likely that inflationary pressures will
increase. This could create some uncertainty regarding interest rate policies
around the world and, therefore, a more volatile outlook for equity markets.
Today, inflation remains at a low level globally. We are confident that the
central banks of the world, led by the Federal Reserve Bank, will be able to
control inflationary pressures through the proper monetary actions. This should
give financial markets confidence in the long term outlook for companies with
well above average growth prospects.

The longer-term outlook for investing in global equities remains favorable. The
world has embraced capitalism, and nations in Europe and Japan are becoming more
shareholder aware each year. These are long term trends, which should reward
shareholders. The other major factor is the proliferation of technology capital
investment on a global basis. Japan, Europe, and Southeast Asia have embraced
the concept of investing in high technology in order to prosper economically. We
continue to have an above average exposure to technology related investments as
this is the key global growth area of the future. There will continue to be
volatility in the world's equity markets, however, over the long term we remain
confident that an investment focus on rapidly growing companies will be
rewarded.

FORTIS SERIES: LARGE CAP GROWTH SERIES
(SUBADVISED BY ALLIANCE)
THIS PORTFOLIO IS DESIGNED FOR INVESTORS WHO WANT TO INVEST IN LARGE
CAPITALIZATION, FAST GROWING COMPANIES.
1999 REVIEW
We are pleased to report that for the calendar year ending December 31, 1999,
the portfolio returned 27.22% outperforming the S&P 500 Index return of 21.04%.
The Series' outperformance compared to the Index was driven by excellent stock
selection across several industry groups. Mirroring the fourth quarter,
technology, communication services and media stocks were among the best
performing for the year. Double-digit earnings growth fueled by the convergence
of cable, telecom, computer and Internet technologies drove the stock prices of
these companies. For the year, retail stocks generally outperformed, as consumer
spending remained strong. Several cyclical stocks, particularly paper and
non-ferrous metals companies, realized strong gains during 1999. Cyclical stocks
rallied due to the expectation that a recovery in the troubled Asian economies
and accelerating global economic growth will lead to increased demand for basic
materials and commodities in the coming year.
Financial and pharmaceutical stocks generally lagged the overall market in 1999.
Financials came under pressure as the year progressed. Investors worried that if
the Federal Reserve continues to increase interest rates to slow the economy and
forestall higher inflation, the earnings of financial companies would be
adversely impacted. Pharmaceutical stocks suffered losses in 1999 due to
investors' concerns about decelerating earnings growth, the relative sparseness
of new product launches and the potential reform of Medicare.
Our investment approach is to hold fairly concentrated positions in the top
twenty-five stocks, which typically represent 65-75% of the total market value
of the portfolio. We research these companies thoroughly and then trade around
these core positions taking advantage of market and individual stock volatility.
Stock selection accounts for two-thirds of the outperformance, while
intra-period trading around the core positions accounts for the remaining
one-third of the outperformance. At year-end, the five largest holdings in the
portfolio were Dell Computer, Microsoft, Associates First Capital Corp., Nokia,
and Tyco.
OUTLOOK
Looking ahead, we believe that economic growth in the United States will remain
robust. Years of restructuring and capital investment, including massive
investments in information technology systems, have positioned U.S. companies to
be highly efficient in manufacturing and distribution and demonstrate
technological leadership. While the strong economic growth experienced in the
U.S. has come with little to no inflation during the last several years, bond
yields in the U.S. have increased in anticipation that the Federal Reserve will
continue to raise interest rates to modestly slow economic growth and dampen
inflation. This combination of higher interest rates and historically high
valuations, particularly for technology and other high multiple stocks that
investors have continued to favor at any price, will likely lead to more market
volatility during 2000. In a volatile market, we expect to add value to the
market's return as we have traditionally through individual stock selection and
active intra-period trading.
The portfolio remains broadly diversified, balancing our positive view of the
fundamentals with a caution on the valuations. We continue to view the industry
dominant, high growth companies in the portfolio that are growing their earnings
on average 20% as attractive. While technology, communication services, and
retail will continue to be areas of emphasis, we will also look to financials,
consumer staples and pharmaceuticals were valuations are generally more
attractive and returns have lagged the market. In addition, we will look
selectively at industrial and basic materials companies that we believe may
benefit from accelerating world economic growth. In each industry sector, we
will focus on those premier companies with strong earnings growth, exceptional
management and market dominance.
We look forward to the year 2000 with an enormous sense of excitement regarding
the technological changes around us. We are eager to face the challenge of
trying to keep the portfolio optimally structured for success based on the
marriage of our fundamental analysis and price considerations--a management
creed we have successfully followed for the last two decades.

FORTIS SERIES FUND: GROWTH STOCK SERIES

THIS PORTFOLIO IS DESIGNED FOR INVESTORS WHO SEEK TO INVEST IN MEDIUM-SIZED
GROWTH COMPANIES THAT HAVE MOVED BEYOND THE VENTURE STAGE.

During the 12 month period ended December 31, 1999, the Growth Stock Series
posted a 55.17% return versus the S&P Mid Cap 400 which posted a 14.70% return.
This index is the most relevant comparison for the Growth Stock Series, as the
portfolio's primary investment focus is mid capitalization stocks, typically
those with a market capitalization between $1 billion and $8 billion.

During the period under review the portfolio's outperformance was attributable
to its overweight position in technology stocks which significantly outperformed
during the fourth quarter of the year. The Morgan Stanley High Technology index
posted a 49% return in the fourth quarter vs. a 15.9% return for the S&P Mid Cap
400. During the past 12 months the fund benefited from holdings such as Siebel
Systems +250%, Univision Communications +240%, and BEA Systems +495%. The
portfolio currently has a slight overweight position in technology, where we
continue to find new and innovative companies especially in telecommunications
and business-to-business e-commerce. Stocks such as SDL Inc, which supplies
optical components for telecommunication networks and Peregrine Systems, which
offers infrastructure management software, are two stocks we currently favor.
Additionally, we see the recent rebound in energy prices as a positive catalyst
for many of the mid cap energy stocks. Within energy we favor BJ Services, which
is a global oil service company and Nabors Industries, which is engaged in land
drilling for oil and gas. We continue to maintain a market weighting in health
care favoring names such as Biovail and Medimune. Lastly, we continue to
underweight consumer cyclical and financial stocks.

Going forward, we expect steady domestic economic growth, moderate inflation,
and a stable to moderate interest rate environment to provide a positive
backdrop for U.S. stock prices. U.S. corporate profits should also see an added
benefit from an economic rebound in Asia. On a relative basis, we believe that
mid cap growth stocks are currently more attractive than their larger cap
brethren and we expect the valuation gap that has developed over the past three
years to narrow. We believe the portfolio is well positioned going forward.

FORTIS SERIES FUND: AGGRESSIVE GROWTH SERIES

THIS PORTFOLIO IS DESIGNED ESPECIALLY FOR THE MOST AGGRESSIVE INVESTOR WHO
WISHES TO INVEST IN SMALLER, EMERGING GROWTH COMPANIES.

During the 12 month period ended December 31, 1999, the portfolio significantly
outperformed both the Russell 2000 and the Russell 2000 Growth indices -- the
widely used benchmark for small capitalization portfolios. The portfolio posted
an 109.25% return during the period versus a 21.36% return for the Russell 2000
Index.

1999 was an extremely good year for small cap stocks, the Russell 2000
outperformed both the Russell 1000 and the S&P 500. Additionally, throughout
much of the year, growth as an investment style outperformed value. The Russell
2000 Growth Index posted a 43.09% return vs. a -1.48% return for the Russell
2000 Value Index.

The outperformance of the portfolio vs. its benchmark is attributable to
superior stock selection, especially in technology. Emulex Corp, a designer,
developer and supplier of fiber channel host adapters and hubs up 229%, Business
Objects, a decision support software company up 303% and Applied Micro Circuits,
a semiconductor company, which supplies to the telecommunications sector, up
335%. The portfolio also benefited from overweight positions in healthcare, and
broadcasting. In addition, the portfolio's performance was enhanced by its
investments in Initial Public Offerings.

We continue to favor technology stocks especially business-to-business
e-commerce companies, and internet infrastructure companies such as Art
Technology Group and Micromuse Inc. In healthcare we favor companies such as
Arthrocare Corp, an emerging orthopedic company and Abgenix Inc, a leading
biopharmaceutical company focused on antibody therapies. Finally, we expect
increased advertising spending from emerging business-to-consumer internet
companies and strong political advertisement spending to be a supportive
backdrop for radio broadcasting companies such as Emmis Communications.

Going forward we expect small cap stocks to perform well, given the current
attractive relative valuations. We continue to expect moderate economic growth
and stable interest rates to support solid earnings growth for small cap stocks.
We are confident the portfolio is positioned to continue to outperform going
forward.

Past performance is not indicative of future performance. Investment return
and principal value will fluctuate so that shares, when redeemed, may be
worth more or less than their original cost. This represents the performance
of the Series itself, without the expenses associated with the variable
annuities or variable universal life insurance policies.
   *  SEC defined total returns, including reinvestment of all dividend and
      capital gains distributions.
  **  Date shares were first offered to the public.
 ***  An unmanaged index of 500 common stocks
****  An unmanaged index of common stocks of the smallest 2000 companies in
      the Russell 3000 Index, which represents approximately 11% of the
      Russell 3000 Index. Going forward, the Series will use the
      Russell 2000 Index because it is better suited for the investment
      strategy of the Series.

Notes to Financial Statements

- --------------------------------------------------------------------------------

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: The Series is an open-end
   management investment company which currently is comprised of eighteen
   separate investment portfolios and series of capital stock: Money Market
   Series, U.S. Government Securities Series, Diversified Income Series, High
   Yield Series, Global Asset Allocation Series, Asset Allocation Series, Value
   Series, Growth & Income Series, S&P 500 Index Series, Blue Chip Stock Series,
   International Stock Series, Mid Cap Stock Series, Small Cap Value Series,
   Global Growth Series, Large Cap Growth Series, Growth Stock Series and
   Aggressive Growth Series, which are diversified portfolios, and Global Bond
   Series which is non-diversified. Each Series has different investment
   objectives and its own investment portfolio and net asset value. The
   investment objectives of the Series, which can be changed at any time without
   the approval of Contract owners, are as follows:

   - The objectives of the "Money Market Series" are high levels of capital
     stability and liquidity and, to the extent consistent with these primary
     objectives, a high level of current income. AN INVESTMENT IN MONEY MARKET
     SERIES IS NEITHER INSURED NOR GUARANTEED BY THE U.S. GOVERNMENT.

   - The objective of the "U.S. Government Securities Series" is to maximize
     total return (from income and market value change), while providing
     shareholders with a high level of current income consistent with prudent
     investment risk through investment primarily in debt securities of varying
     maturities which have been issued, guaranteed, insured or collateralized by
     the United States Government or its agencies or instrumentalities.

   - The objective of the "Diversified Income Series" is to maximize total
     return (from income and market value change), by investing primarily in a
     diversified portfolio of government securities and investment grade
     corporate bonds.

   - The objectives of the "Global Bond Series" is total return from current
     income and capital appreciation. The Series invests in a global portfolio
     principally consisting of high quality fixed-income securities of
     governmental and corporate issuers and supranational organizations.

   - The objective of the "High Yield Series" is maximum total return (from
     income and market value change), by investing primarily in high-yield,
     high-risk fixed-income securities, which may not be suitable for all
     investors.

   - The objective of the "Global Asset Allocation Series" is maximum total
     return, to be derived primarily from capital appreciation, dividends and
     interest, by following a flexible asset allocation strategy investing in
     global securities.

   - The objective of the "Asset Allocation Series" is maximum total return on
     invested capital, to be derived primarily from capital appreciation,
     dividends, and interest.

   - The primary objective of the "Value Series" is short and long-term capital
     appreciation. Current income is only a secondary objective. The Series
     invests primarily in equity securities and selects stocks based on the
     concept of fundamental value.

   - The objectives of the "Growth & Income Series" are capital appreciation and
     current income, which it seeks by investing primarily in equity securities
     that provide an income component and the potential for growth.

   - The objective of the "S&P 500 Index Series" is to replicate the total
     return of the Standard & Poor's 500 Composite Stock Price Index primarily
     through investments in equity securities.

   - The primary objective of the "Blue Chip Stock Series" is long-term growth
     of capital. Current income is a secondary objective, and many of the stocks
     in the Series' portfolio are expected to pay dividends.

   - The objective of the "International Stock Series" is capital appreciation
     by investing primarily in the equity securities of non-United States
     companies.

   - The objective of the "Mid Cap Stock Series" is total investment returns
     (including capital appreciation and income) that consistently outperform
     the Standard & Poor's 400 MidCap Index. The Series attempts to maintain a
     diversified holding in common stocks of medium capitalization companies
     with a market value between $200 million and $5 billion.

   - The objective of the "Small Cap Value Series" is capital appreciation. The
     Series invests primarily in common stocks of small companies that are out
     of favor with markets or that have not yet been discovered by the broader
     investment community and are therefore believed to be undervalued.

   - The primary objective of the "Global Growth Series" is long-term
     appreciation, which it seeks primarily by investing in a global portfolio
     of equity securities, allocated among diverse international markets.

   - The objective of the "Large Cap Growth Series" is long-term growth of
     capital. The Series invests primarily in the equity securities of a limited
     number of large, carefully selected, high quality United States companies
     whose securities are believed likely to achieve superior earnings growth.

   - The primary objective of the "Growth Stock Series" is short and long-term
     capital appreciation. The Series will seek to meet this objective by
     investing primarily in common stocks and securities convertible into common
     stocks.

   - The objective of the "Aggressive Growth Series" is maximum short and
     long-term capital appreciation by investing primarily in equity securities
     of small and medium sized companies that are early in their life cycles,
     but which have the potential to become major enterprises, and of more
     established companies that have the potential for above-average capital
     growth.

   The Articles of Incorporation of Fortis Series Fund, Inc. permits the Board
   of Directors to create additional portfolios in the future.

   Shares of the Fund will not be sold directly to the public, but sold only to
   Fortis Benefits Insurance Company or First Fortis Life separate accounts in
   connection with variable insurance contracts and policies.

   The inception of Mid Cap Stock Series, Small Cap Value Series and Large Cap
   Growth Series was March 25, 1998, and the commencement of operations was
   May 1, 1998.

   The significant accounting policies followed by the Portfolios are summarized
   as follows:

   SECURITY VALUATION: Investments in securities traded on a national securities
   exchange or on the NASDAQ National Market System are valued at the last
   reported sales price. Securities for which over-the-counter market quotations
   are readily available are valued on the basis of the last current bid price.
   An outside pricing service may be utilized to provide such valuations. For
   fixed income securities, the pricing service may employ electronic data
   processing techniques and/or a matrix system to determine valuations using
   methods which include consideration of yields or prices of bonds of
   comparable quality, type of issue, coupon, maturity and rating indications as
   to value from dealers, and general market conditions. Securities for which
   quotations are not readily available are valued at fair value as determined
   in good faith by management under supervision of the Board of Directors.
   Short-term investments, with maturities of less than 60 days when acquired,
   or which subsequently are within 60 days of maturity, are valued at amortized
   cost, with the exception of Money Market Series. Pursuant to Rule 2a-7 under
   the Investment Company Act of 1940, Money Market Series' investments are
   valued at amortized cost which assumes a constant amortization to maturity of
   discount or premium.

   SECURITIES PURCHASED ON A WHEN-ISSUED BASIS: Delivery and payment for
   securities that have been purchased by all portfolios except for Money Market
   Series and Growth Stock Series on a forward commitment or when-issued basis
   can take place a month or more after the transaction date. During this
   period, such securities are subject to market fluctuation and the portfolio
   maintains, in a segregated account with its custodian, assets with a market
   value equal to the amount of its purchase commitments. As of December 31,
   1999, U.S. Government Securities Series and Asset Allocation Series entered
   into outstanding when-issued or forward commitments of $2,450,000 and
   $2,450,000 respectively.

   Consistent with its ability to purchase securities on a when-issued basis,
   the U.S. Government Securities Series, Diversified Income Series and Asset
   Allocation Series have entered into transactions to defer settlement of its
   purchase commitments. As an inducement to defer settlement, the portfolio
   repurchases a similar security for settlement at a later date at a lower
   purchase price relative to the current market. This transaction is referred
   to as a Dollar Roll.

   FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS:
   Securities and other assets and liabilities denominated in foreign currencies
   are translated daily into U.S. dollars at the official rate of exchange.
   Foreign currency amounts related to the purchase or sale of securities,
   income and expenses are translated at the exchange rate on the transaction
   date. The effect of changes in foreign exchange rates on realized and
   unrealized security gains or losses is reflected as a component of such gains
   or losses. In the statement of operations, net realized gains or losses from
   foreign currency transactions may arise from sales of foreign currency,
   closed forward contracts, exchange gains or losses realized between the trade
   date and settlement date on security transactions, and other translation
   gains or losses on dividends, interest income and foreign withholding taxes.

   Certain portfolios may enter into forward foreign currency exchange contracts
   for operational purposes and to attempt to minimize the risk from adverse
   exchange rate fluctuations. The net U.S. dollar value of foreign currency
   underlying all contractual commitments held by the portfolio and the
   resulting unrealized appreciation or depreciation are determined using
   foreign currency exchange rates from an independent pricing service. The
   portfolio is subject to the credit risk that the other party will not
   complete the obligations of the contract.

   SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME: Security transactions
   are accounted for on the trade date, and dividend income is recorded on the
   ex-dividend date for all funds or upon receipt of ex-dividend notification in
   the case of certain foreign securities. Interest income is recorded on the
   accrual basis. Realized security gains and losses are determined using the
   identified cost method. Each Portfolio amortizes bond premium, market
   discount and original issue discount. For the year ended December  31, 1999,
   the cost of purchases and proceeds from sales of securities for Money Market
   Series were $630,111,607 and $583,217,546, respectively. The cost of
   purchases and proceeds from sales of securities (other than short-term
   securities) for the other portfolios were as follows:

   LENDING OF PORTFOLIO SECURITIES: At December  31, 1999, securities were on
   loan to brokers from the portfolios. For collateral, the portfolios custodian
   received cash which is maintained in a separate account and invested by the
   custodian in short-term investment vehicles. The risk to the portfolios in
   security lending transactions are that the borrower may not provide
   additional collateral when required or return the securities when due and
   that the proceeds from the sale of investments made with cash collateral
   received will be less than amounts required to be returned to the borrowers.
   The value of securities on loan, collateral, and fee income from securities
   lending as of, and for the year ended December  31, 1999 was as follows:

   INCOME TAXES: The portfolios intend to qualify, under the Internal Revenue
   Code, as regulated investment companies and if so qualified, will not have to
   pay federal income taxes to the extent their taxable net income is
   distributed.

   Net investment income and net realized gains may differ for financial
   statement and tax purposes. The character of distributions made during the
   year from net investment income or net realized gains may, therefore, differ
   from their ultimate characterization for federal income tax purposes. Also,
   due to the timing of dividend distributions, the fiscal year in which amounts
   are distributed may differ from the year that the income or realized gains
   (losses) were recorded by the portfolios. The effect on dividend
   distributions of certain current year permanent book-to-tax differences is
   reflected as excess distributions of net realized gains in the statements of
   changes in net assets and the financial highlights.

   On the Statements of Assets and Liabilities, due to permanent book-to-tax
   differences, accumulated net realized gain (loss) and undistributed net
   investment income have been increased (decreased), resulting in a net
   reclassification adjustment to increase (decrease) paid-in-capital by the
   following:

   For federal income tax purposes the portfolios had the following capital loss
   carryovers at December 31, 1999, which, if not offset by subsequent capital
   gains, will expire in 2000 through 2008. It is unlikely the Board of
   Directors will authorize a distribution of any net realized gains until the
   available capital loss carryovers have been offset or expire.

</TABLE>

   Pursuant to guidelines adopted by the Board of Directors, certain
   unregistered securities are determined to be liquid and are not included
   within the percent limitations specified above.

   INCOME AND CAPITAL GAINS DISTRIBUTIONS: The portfolios intend to make income
   and capital gains distributions, if any, on an annual basis. All
   distributions will be reinvested in additional shares of the portfolio at net
   asset value.

   USE OF ESTIMATES: The preparation of financial statements in conformity with
   generally accepted accounting principles requires management to make
   estimates and assumptions that affect the reported amounts of assets and
   liabilities and disclosure of

96
<PAGE>

- --------------------------------------------------------------------------------
   contingent assets and liabilities at the date of the financial statements and
   the reported amounts of increase and decrease in net assets from operations
   during the reporting period. Actual results could differ from those
   estimates.
   BANK BORROWINGS: Several Fortis Funds, including Series High Yield, Series
   Asset Allocation, Series Value, Series Growth & Income, Series Global Growth,
   Series Growth Stock and Series Aggressive Growth, have a revolving credit
   agreement with Norwest Bank Minnesota N.A., whereby the funds are permitted
   to have a bank borrowing for temporary and emergency purposes to meet large
   redemption requests by shareholders; and cover securities purchased when
   matched or when earlier trades have failed. The agreement, which enables the
   funds to participate with other Fortis Funds, permits borrowings up to $25
   million, collectively. Interest is expensed to each participating fund based
   on its borrowings and will be calculated at the borrowers option of: 1) the
   Prime Index; 2) the Federal Funds rate plus a "Margin" of 37.5 basis points,
   or; 3) the Libor rate plus a "Margin" of 37.5 basis points. The Prime Index
   is defined as the higher of: A) the rate that Norwest Bank Minnesota N.A.
   announces from time to time as its prime rate or B) the Federal Funds rate
   plus 50 basis points. Each fund pays a commitment fee equal to its pro rata
   share of the amount of the credit facility at a rate of 0.08% per annum. The
   funds had no borrowings during the year ended December 31, 1999.

   FUTURES TRANSACTIONS: Certain portfolios may invest in financial futures
   contracts in order to gain exposure to or protect against changes in the
   market. The S&P 500 Index Series and Mid Cap Stock Series are exposed to
   market risk as a result of changes in the value of the underlying financial
   instruments (see the Notes to the Schedule of Investments). Investment in
   financial futures require the funds to "mark to market" on a daily basis,
   which reflects the change in the market value of the contract at the close of
   each day's trading. Accordingly, variation margin payments are received or
   made to reflect daily unrealized gain or losses. When the contracts are
   closed, the funds recognize a realized gain or loss. These investments
   require initial margin deposits with a custodian, which consist of cash or
   cash equivalents. The amount of these deposits is determined by the exchange
   or Board of Trade on which the contract is traded and is subject to change.
   Contracts open as of December 31, 1999, and their related unrealized market
   appreciation are set forth in the Notes to the Schedule of Investments.

2. PAYMENTS TO RELATED PARTIES: Fortis Advisers, Inc., (Advisers), is the
   investment adviser for each series. Investment advisory and management fees
   are based on each series' average daily net assets and decrease in reduced
   percentages as average daily net assets increase.

   The following chart represents the annual fee percentages:

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders

Fortis Series Fund, Inc.:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of Money Market Series, U.S.
Government Securities Series, Diversified Income Series, Global Bond Series,
High Yield Series, Global Asset Allocation Series, Asset Allocation Series,
Value Series, Growth & Income Series, S&P 500 Index Series, Blue Chip Stock
Series, International Stock Series, Mid Cap Stock Series, Small Cap Value
Series, Global Growth Series, Large Cap Growth Series, Growth Stock Series and
Aggressive Growth Series (series within Fortis Series Fund, Inc.) as of December
31, 1999 and the related statements of operations for the year then ended, and
the statements of changes in net assets and the financial highlights for each of
the periods presented. These financial statements and the financial highlights
are the responsibility of fund 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 the 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. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased and sold but not received or delivered,
and securities on loan, we carry out other appropriate 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 the financial highlights referred
to above present fairly, in all material respects, the financial position of
Money Market Series, U.S. Government Securities Series, Diversified Income
Series, Global Bond Series, High Yield Series, Global Asset Allocation Series,
Asset Allocation Series, Value Series, Growth & Income Series, S&P 500 Index
Series, Blue Chip Stock Series, International Stock Series, Mid Cap Stock
Series, Small Cap Value Series, Global Growth Series, Large Cap Growth Series,
Growth Stock Series, and Aggressive Growth Series as of December 31, 1999 and
the results of their operations for the year then ended, and the changes in
their net assets and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.
