FORTIS SERIES FUND, INC. ANNUAL REPORT,
DECEMBER 31, 1996
 
DEAR SHAREHOLDER:
 
1996. What a year for the stock and bond markets alike! Often one market or the
other will dominate the news depending on its performance; this year, both
received attention albeit for different reasons. It's interesting to note that
of the record-breaking performance on the Standard & Poor's 500 Stock Index,
more than half resulted from just 25 stocks. On the other hand, we find the bond
market reacting very negatively to an unexpectedly strong U.S. economy. What
this information tells us is that we must weigh all of the contributing factors
before making investment decisions. We must identify and remain true to our
long-term goals. In so doing, it's critical to work closely with your
representative who, through extensive training, experience and education, can
help you determine the investment portfolio(s) that will best match your needs.
 
Along the same vein, we were also pleased to mark history this year by bringing
you three more investment selections. On May 1, we added the Value Portfolio,
which is managed by Fortis Advisers, Inc.; the S&P 500 Stock Index Portfolio,
which is subadvised by Dreyfus; and the Blue Chip Stock Portfolio, which is
subadvised by T. Rowe Price. The addition of these portfolios brings your
investment choices to 15, and the number of experienced money management firms
to six. At this time, we're pleased to offer you the annual review of the Fortis
Series Fund for the 12-month investment period ended December 31, 1996.
 
EQUITY MARKET REVIEW AND OUTLOOK
 
Many of the world's equity (or stock) markets performed favorably in 1996, as
measured by the 11.7 percent gain registered by the Morgan Stanley Capital
International World Index. The United States was the best-performing major
market during the year, with a return of 22.98 percent as measured by the
Standard & Poor's 500 Stock Index. The one major market that significantly
lagged in performance during the year was Japan, which registered a decline in
U.S. dollar terms. Key factors in the market's performance over the past several
years have been favorable global liquidity, (or the amount of money available
for investment in financial assets) and a highly favorable economic background.
 
A moderately-growing global economy has led to slowing inflation and lower
interest rates outside the United States. Financial markets are sensitive to
trends in inflation because it impacts both the level of interest rates and the
valuation placed on common stocks. Global inflation has declined from 7 percent
in 1995 to an expected level of below 4 percent in 1997. Low levels of inflation
going forward will help maintain a positive environment for financial assets.
 
The outlook for financial market performance in 1997 is as always uncertain;
however, many of the positive trends that have been in place for the past
several years are likely to persist. The driving forces of the equity market
returns have been strongly growing corporate earnings and higher valuation
levels for equities. Both of these factors are likely to moderate as we enter
1997.
 
The concerns over slowing corporate earnings growth are legitimate and will
likely impact individual stock performance in 1997. The bull market, which began
in 1991, is one of the longest on record. Although the major indices such as the
S&P 500 and the Dow Jones Industrial Average have not experienced a significant
correction since 1991, other sectors of the market have. Both the mid-sized and
smaller high growth company sectors have been through sharp corrective phases
during 1992, 1994, and the second half of 1996. This corrective process has
helped reduce some of the excesses in the valuation for growth-oriented
equities.
 
Looking forward, we feel that many mid-size growth companies offer reasonable
value relative to their respective growth rates. In general, the outlook for
1997 must
 
2
<PAGE>
incorporate a degree of volatility in the stock market. Investors will likely
react fairly strongly to changes in the outlook for corporate earnings growth,
inflation, or changes in interest rates.
 
The longer term outlook remains favorable for equity investors. We have been in
a most favorable period for investment with slow-growing economies and low
levels of inflation. This scenario is likely to persist for some time and should
provide a favorable backdrop for equity investors.
 
FIXED INCOME MARKET REVIEW AND OUTLOOK
 
When 1996 began, we expected a marginally expanding U.S. economy with minimal
inflationary pressures. In addition, expectations were that the Federal Reserve
would lower short-term rates and that the federal budget would be balanced. But
these favorable views unwound quickly when budget negotiations failed to make
progress on the deficit, and the February employment statistics contributed to a
changed market outlook with interest rates moving higher. As the bond market
started to slide, we made swift defensive adjustments to the portfolios, a
strategy that paid-off as bonds continued to trend lower through the first half
of 1996.
 
Early in the fourth quarter, economic indicators suggested that the economy was
slowing and the bond market rallied, only to reverse course once again to end
the year with slightly higher yields. In general, 1996 was a good performance
year for spread product (mortgages and government agency notes) when compared to
comparable maturity treasuries. These sectors had greater returns than did
comparable treasury securities as yield spreads held steady or tightened.
 
Our view is that the 1997 economy will continue to expand and inflation will
continue to be under control. On a global basis, we concur with those who
subadvise our global bond portfolio: due to the structural problems many
countries face in conjunction with economic growth, bond yields around the world
are not likely to decline significantly from current levels.
 
As always, the identification of improving situations and undervalued securities
is done through extensive credit research by our portfolio managers and in-house
research staff. We believe the quality of our research should give our
portfolios a performance advantage.
 
YOU ARE IMPORTANT TO US.

REVIEW
 
When the year began, we expected short-term rates to decline due to a weakening
economy. Our forecast proved accurate, initially evidenced by 60-day commercial
paper rates, which fell by nearly half of a percentage point by mid-February.
 
While signs of an economic slowdown also prompted the Federal Reserve Bank to
lower the federal funds rate, the drop in market rates was short-lived. The
unexpectedly strong February employment report and subsequent economic data
caused rates to retrace most of their decline by the end of March.
 
After the volatility of the first quarter, short-term rates were relatively
stable over the next nine months, reflecting a moderately growing economy with
low inflation. This condition supported the Fed's decision to leave the federal
funds rate unchanged through year-end.
 
In 1996, the portfolio's return was 5.17 percent, down from 5.71 percent in 1995
when short-term rates were higher. During the year, the portfolio's yield
followed a pattern similar to that of the market: it declined in the first
quarter; rose in the second quarter; and leveled off over the last half of the
year.
 
Our strategy throughout the year was to keep the fund's average maturity between
50 and 60 days. This strategy helped us take advantage of higher yields on
longer maturities during a period in which we did not anticipate rates to rise.
In December, we shortened the average maturity to take advantage of the higher
yields available on shorter maturities due to year-end pressures. At the close
of this reporting period, the fund was 100 percent invested in high quality
securities with an average maturity of 45 days.
 
OUTLOOK
 
Recently there have been indications that the economy is more robust than we had
expected. In the event that growth accelerates, we will lower the fund's average
maturity in anticipation of higher short-term rates. However, our current view
of 1997 is that the economy will continue to expand at a real growth rate
between 2.5 percent and 3 percent, with inflation this year at about 3 percent
to 3.5 percent.

RETURN, AS WELL AS A RELATIVELY HIGH LEVEL OF CURRENT INCOME. IT FOCUSES ITS
INVESTMENTS IN U.S. GOVERNMENT BONDS, TREASURIES AND MORTGAGE-BACKED SECURITIES.
 
REVIEW
 
The bond market began 1996 with the 30-year treasury bond (long bond) yielding
5.95 percent. In addition, expectations were that the Federal Reserve would
lower short-term rates and that the federal budget would be balanced. These
favorable views unwound quickly when budget negotiations failed to make progress
on the deficit, the February employment statistics contributed to a changed
market outlook, and interest rates moved higher.
 
During the year's second and third quarters, the long bond essentially traded in
a range from 6.70 percent to 7.20 percent. Early in the fourth quarter, economic
indicators suggested that the economy was slowing and the bond market responded
by rallying to a 6.35 percent yield on the long bond. It then reversed course
and ended the year with a 6.64 percent yield. In general, 1996 was a good year
for returns for spread product (mortgages and government agency notes) when
compared to comparable maturity treasuries. These sectors had greater returns
than did comparable treasury securities as yield spreads held steady or
tightened.
 
We began 1996 with a portfolio duration of approximately five-and-a-half years.
(Duration is a measure of the portfolio's average maturity, and, subsequently,
its sensitivity to changes in interest rates.) Upon release of February's
stronger than expected payroll numbers, however, we shortened duration to help
minimize volatility. As of year end, the portfolio's duration continued to be
under five years. Believing that the market was in a trading range, we made only
modest adjustments to the portfolio's duration over the last six months of this
period. Our strategy was to lengthen the portfolio's duration as interest rates
moved toward the high end of the trading range, and shorten the portfolio as
interest rates approached the low end of the trading range. This strategy allows
the portfolio to have a stronger response than the market to a rally, and a
milder reaction to a sell-off.
 
We also reduced our exposure to the mortgage market in August, after
successfully overweighting it earlier in the year. We have kept it to around
one-third of the portfolio since. We continue to have 20 percent of our holdings
in agency notes, since we feel the extra yield these securities offer over
treasuries will enhance the total rate of return. These combined efforts
produced a positive return of 2.21 percent. The portfolio, however, did lag the
3.28 percent return of its benchmark, the Lehman Brothers Intermediate
Government Bond Index.
 
OUTLOOK
 
Going forward, we believe the economy will continue to expand through 1997 at a
rate of about 2.5 percent to 3 percent, after inflation. We also expect
inflation to remain modest, albeit somewhat higher than 1996's rate of just 2.6
percent. As a result, we look for the market to trade in a range, with the
30-year treasury bond yielding between 6.5 percent to 7.25 percent.

REVIEW
 
A difficult year for bonds, 1996 took a toll on fixed income markets, in
general. The Salomon Brothers Broad Investment Grade Index ended the year with a
3.62 percent return, and the Lehman Brothers Aggregate Index with a 3.63 percent
return. While down significantly from a year ago, the return on this portfolio
exceeded these fixed income indexes by more than 0.5 percent. The following
information details our course of action throughout the year.
 
Our investment strategy entering 1996 was based on our outlook for a marginally
expanding U.S. economy with little or no inflationary pressure. Accordingly, we
positioned our portfolio to reflect our positive view on bonds. The portfolio
duration was just over five years when the strong February employment statistics
suggested a more vigorous economy. (Duration is a measure of the portfolio's
average maturity, and, subsequently, its sensitivity to changes in interest
rates.) As the bond market started to sell-off, we made a swift downward
adjustment to the duration that paid off as the market continued to trend lower
through the first half of 1996.
 
For most of the second half of the year, we maintained the duration of the
portfolio between 4.5 and 4.75 years as the market traded in a range. In
December 1996, we lengthened the duration of the portfolio to approximately 5.75
years, which we deemed to be about average within our competitive universe or
neutral for strategic reasons.
 
In 1996 we reduced our exposure to governments and agencies to overweight
sectors that offered higher yields, such as corporate bonds and asset-backed
securities. Strong fundamentals and higher demand for yield promised a higher
performance in these market areas, and indeed these sectors turned out to be the
highest performing for the year. In our quest for yield, we have taken a more
conservative approach by limiting our exposure to lower-quality bonds.
 
OUTLOOK
 
Our view is that the 1997 economy will continue to expand and inflation will
continue to be under control. Should this forecast prove true, interest rates
are likely to move within trading ranges determined by the strength of the
economic data releases. Our strategy in this scenario will be to lengthen the
portfolio duration when rates approach what we perceive to be the high end of
the range, and shorten it when rates approach the lower end. This strategy
allows the portfolio to have a stronger response than the market to a rally, and
a milder reaction to a sell-off.
 
We will continue to overweight corporate bonds and asset-backed securities, as
we believe that corporate profits will remain positive and demand for yield will
continue. Our main focus in corporate bonds will be on industry sectors that
present improving fundamentals and lower business and event risks.
Identification of improving situations and undervalued securities is done
through extensive credit research by our portfolio managers and in-house
research staff. We believe the quality of our research should give the portfolio
a performance advantage.

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.
 
REVIEW
 
Superior currency management and bond market selection added value over this
reporting period, helping the Global Bond Portfolio achieve its 3.15 percent
return. Hedging foreign currency exposure into the dollar and the underweighting
of the U.S. and Japanese bond markets (to the benefit of European markets) drove
relative performance.
 
On the currency side, the portfolio maintained an overweight position in the
United States, with significant foreign currency exposure hedged into the
dollar. On the bond side, the portfolio maintained an underweight exposure to
both the United States and Japanese bond markets while emphasizing the European
markets. Within Europe, the period saw a gradual shift from the core markets
(especially Germany) to the higher-yielding peripheral markets (especially
Denmark and Spain).
 
OUTLOOK
 
The best may have been seen of the benign liquidity conditions that have been
supporting financial markets. The currency policy shift in Japan and stronger
than expected economic growth in the United States will produce pressures for
higher interest rates. Within Europe, a broad-based currency (EMU) is likely,
and synchronized fiscal tightening ahead of monetary union will slow economic
growth. Thus, the European bond markets appear to offer the best value on a
global basis. On the currency front, dollar strength will continue on the back
of robust economic growth in the United States.

FORTIS SERIES FUND: HIGH YIELD PORTFOLIO
 
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.
 
REVIEW
 
Aided by moderate growth and low inflation in the U.S. economy, a vibrant stock
market, and unflagging demand from fixed income investors, the high yield bond
market marched to a second straight year of double-digit returns in 1996. Over
the last 10 years, the high yield bond sector has been the best-performing class
of fixed income securities. In fact, in terms of 1996 total return performance,
the high yield bond sector was outpaced only by convertible bonds and emerging
market debt.
 
For the year ended December 31, 1996, the Fortis High Yield Portfolio
outperformed the average total return of the Lehman Brothers High Yield Bond
Index, returning 10.52 percent versus 10.43 percent, and the portfolio
underperformed its Lipper Analytical Services Peer Group. Several factors had an
impact on the portfolio's performance:
 
* The bonds of Marvel Holdings, which held a 2 percent position in the
portfolio, declined substantially when the company reported poor operating
results and filed for bankruptcy.
 
* The telecommunications and cable television sectors, our two largest industry
allocations, delivered below-average results due to concerns over capital needs
and the zero-coupon structure of many telecommunication issues.
 
* The strength of the economy and low default rates generally rewarded the
lowest quality, highest risk sectors of the high yield bond market. In
hindsight, our decision to improve the overall credit quality and trading
liquidity of the portfolio, and thus lessen the portfolio's risk, proved to be
somewhat counterproductive under these market conditions.
 
After carefully reviewing our strategy for the portfolio, we are currently
maintaining its focus on the telecommunications and cable television sectors,
which we believe, over the long term, will provide the rates of growth necessary
to pay down the debt of the highly-leveraged companies within those industries.
Despite the market's appetite for very low credit quality in 1996, we are not
lowering the current credit quality of the portfolio because we are concerned
that corporate profits may fall below market expectations in the near term.
Finally and most importantly, we have renewed our commitment to stringent credit
analysis and review.
 
OUTLOOK
 
The formula for good returns in the high yield bond market appears to be in
place as we begin 1997. Moderate economic growth, low inflation, and a soaring
stock market usually propel lower-rated bond prices higher and yields lower.
Cautionary signals are still present, however. The near-term outlook for
interest rates is higher, a scenario that would negatively affect the market
value of fixed income securities. And U.S. stock prices, which have risen over
50 percent in two years, may embody an overly-optimistic view of corporate
earnings growth.

FORTIS SERIES FUND: ASSET ALLOCATION PORTFOLIO
 
DESIGNED FOR INVESTORS WHO SEEK TOTAL RETURN FROM A BLEND OF GROWTH POTENTIAL
AND CURRENT INCOME. THE PORTFOLIO MANAGERS SELECT A MEDLEY OF U.S. STOCKS, BONDS
AND MONEY MARKETS IN PERCENTAGES THAT MAY VARY WITH CURRENT MARKET CONDITIONS.
 
REVIEW
 
In the Asset Allocation Portfolio, the allocation mix is altered as the outlook
for the equity and fixed income markets change. In 1996, this portfolio, due to
its balanced nature, outperformed the bond markets, but realized a return lower
than that of the Standard & Poor's 500 Stock Index. The stock allocation was
increased gradually over the latest period from 45 percent in mid-1996 to
represent 57 percent of the portfolio by the end of the year. Bond holdings
constitute the remaining 40 percent of the portfolio.
 
STOCKS
 
The portfolio's equity portion is invested primarily in large capitalization
companies with superior earnings prospects. This year presented interesting
challenges. For the first six months of the year, the retail and
telecommunications sectors enhanced the portfolio's return. However, by the end
of the year, these two sectors actually detracted from performance. Other
holdings in the technology, financial, health care, and energy sectors helped
contribute positively to overall performance.
 
BONDS
 
In the bond portion of the fund, we started 1996 with a constructive outlook for
interest rates. This view was based on our forecast of a marginally expanding
U.S. economy with little or no inflationary pressure. Accordingly, we positioned
our portfolio to reflect our positive view on bonds.
 
However, in March 1996, the economic picture was changed by the February
employment statistics that told of greater strength in the economy than we had
anticipated. We immediately assumed a neutral posture of a 4.5 year duration as
we awaited further evidence of economic strength. That duration adjustment paid
off as the market continued to trend lower through the first half of 1996. For
most of the second half of the year, we maintained the duration of the portfolio
within the range of 4.5 to 4.75 years as the market traded in a range.
 
Our sector allocation strategy throughout 1996 was to overweight such higher
yielding bonds as corporate bonds and asset-backed securities. We believed that
corporate profits would remain strong and demand for yield would continue. These
sectors turned out to be the highest performing for the year. Within the
corporate sector, we took a more conservative approach in terms of credit
exposure. Although we are permitted to hold up to 30 percent of lower quality
bonds, we limited our exposure to 12 percent to 15 percent.
 
OUTLOOK
 
Looking forward, we think the economy will continue to show signs of strength,
and we expect inflationary pressures to remain modest. Should this forecast
prove true, interest rates are likely to move within trading ranges determined
by the strength of the economic data releases. Therefore, we are not favoring a
duration bias in the near term, but will make duration adjustments as we
approach the trading range boundaries.
 
As always, we will continue to focus on individual security selection, seek a
thorough understanding of each credit to avoid deterioration, and strive to help
the portfolio benefit from improving situations.

FORTIS SERIES FUND: GLOBAL ASSET ALLOCATION PORTFOLIO
(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. MONEY MANAGERS INVEST IN GLOBAL STOCKS,
BONDS AND MONEY MARKETS IN PERCENTAGES THAT MAY VARY WITH MARKET CONDITIONS.
 
REVIEW
 
For the year, as a whole, the portfolio appreciated by 12.72 percent. This
favorably compares to the returns by the portfolio's measures or "benchmarks."
The Morgan Stanley Capital International World Index (stocks) saw a 11.7 percent
return and the Salomon Brothers World Government Bond Index realized an 8.36
percent return.
 
Contributing to this portfolio's success this year were a number of factors,
including overweighted positions in Canadian bonds, high-yielding European
bonds, the U.S. dollar and sterling currency. An underweight position in
Japanese equities also made a positive contribution. Specific stock selection in
Australia, Germany, Italy, Japan and the United States also benefited the
overall return.
 
Factors that detracted from the portfolio's performance include a slightly
defensive overall bond duration, an overweighted bond position in the United
Kingdom and selected French equities.
 
The stance of the bond portion of the portfolio remained little changed
throughout the quarter. Namely, the portfolio was overweighted in Europe at the
expense of the Japanese and U.S. markets, with overall duration slightly shorter
than benchmark. We added to the Canadian bond and currency exposure, slightly
reduced Denmark and built-up relative exposure to the sterling bond market. In
addition, Dutch bonds were sold and Swedish bonds increased.
 
On the stock or equity side, there were only minor changes in our investment
strategy. The geographic allocation was the result of stock-picking decisions,
and, at the end of this reporting period, the equities were split 40 percent
U.S., 13 percent Japan, 44 percent Europe and 3 percent other.
 
Cash levels averaged 10 percent during the fourth quarter and were held in
dollar deposits and Treasury bills.
 
During the fourth quarter, we were satisfied with the portfolio's allocation and
did not make any specific moves to change its balance. As the year closed, the
fixed income portion was held near the 40 percent benchmark, with global
equities around 50 percent.
 
OUTLOOK
 
We do not foresee a full-blooded global recovery in 1997, as Europe, Japan and
certain emerging markets have structural problems regarding economic growth,
while bond yields around the world are unlikely to decline significantly from
current levels.
 
This leaves us cautious on world stock markets generally and cyclicals
specifically after recent relative strength. Our preferred investment
characteristic for 1997 is strong cash generation in a weakish global economy,
which draws us to brandname stocks whose unglamorous growth rates have left them
relatively cheap.

REVIEW
 
As a relatively new addition to the Fortis Series Fund, the Value Portfolio
opened to investors on May 1, 1996. For the eight months ended December 31, the
portfolio achieved a total return of 11.49 percent, compared to 14.53 percent
for the Standard & Poor's 500 Stock Index the portfolio's benchmark.
 
While satisfactory, the stock market's upward, but choppy, progress was
characterized by wide disparities in the performance of individual stocks and
sectors. For example, technology stocks sold off sharply in the summer, only to
rebound strongly by the end of the year. Although the economy has been strong,
investors remain concerned that the strongest part of the current business
expansion is aging. Consequently, the shares of cyclical companies have been
performing poorly. In contrast, a handful of blue chip stocks have been
performing well because they offer investors predictable earnings growth in an
uncertain environment.
 
Throughout 1996, we increased our exposure to such "blue chip" investments, and
reduced our exposure to the shares of companies vulnerable to the business
cycle. However, we also remained opportunistic. For example, the sharp decline
in the prices of many technology shares presented an attractive opportunity to
add to our holdings. These purchases appreciated nicely toward the end of 1996.
 
OUTLOOK
 
Looking forward, our main concern is that profit margins are near their peak for
this business cycle. With profit margins in the next few years more likely to
decline than rise, earnings growth will probably become scarce. In this
environment, it will become increasingly difficult to identify companies that
will satisfy our primary buy criteria of having accelerating earnings over the
next few years. Accordingly, we will need to rely more heavily on our secondary
criteria, which is to find companies that are reasonably priced in relation to
their long-term growth rates. As a result, our disciplines have led us to invest
more heavily in defensive stocks.

FORTIS SERIES FUND: GROWTH & INCOME PORTFOLIO
 
THIS PORTFOLIO OFFERS A SOLUTION TO INVESTORS WHO WANT TO COMBINE CONSERVATIVE
GROWTH OPPORTUNITIES WITH INCOME POTENTIAL. IT FOCUSES ON COMPANIES WITH
ATTRACTIVE CURRENT DIVIDEND YIELDS RELATIVE TO THE STANDARD AND POOR'S 500 STOCK
INDEX. THE PORTFOLIO IS WELL DIVERSIFIED WITH EXPOSURE TO MANY SECTORS OF THE
ECONOMY.
 
REVIEW
 
During the period under review, the Growth & Income Portfolio performed in line
with the market as measured by the Standard & Poor's 500 Stock Index. The
portfolio's performance was enhanced by selected holdings in the financial,
energy and healthcare sectors. Detracting from performance were positions in the
retail and telecommunications sectors.
 
The Growth & Income Portfolio concentrates on those sectors in the market that
offer a combination of earnings growth and above average current yields. The
technology sector generally does not provide above average current yields, hence
our underweighted position in this sector.
 
OUTLOOK
 
We anticipate a continuation of moderate economic growth, coupled with modest
inflation in the months ahead. This is generally a positive environment for the
investment of financial assets. In reflection of these factors, the stock market
has performed well and is currently accorded somewhat above average valuations.
Therefore, we have slightly above average cash reserves in the portfolio to take
advantage of opportunities as they present themselves.

FORTIS SERIES FUND: S&P 500 STOCK INDEX PORTFOLIO
(SUBADVISED BY DREYFUS)
 
THIS PORTFOLIO IS DESIGNED ESPECIALLY FOR INVESTORS WHO WANT TO EMULATE THE
TOTAL RETURN OF THE STANDARD & POOR'S 500 STOCK INDEX.
 
REVIEW
 
The Fortis S&P 500 Index Portfolio became available on May 1, 1996. For the
eight month period ended December 31, the portfolio realized a total return of
14.29 percent, while the Standard & Poor's 500 Stock Index had a total return of
14.53 percent.
 
This portfolio is designed to passively replicate the large capitalization
United States equity market as it is represented by the S&P 500 Index. In 1996,
large capitalization equities provided strong returns, outperforming both small
and mid-capitalization stocks.
 
Among the best-performing groups in the S&P 500 in 1996 were oil and gas
drilling companies, electronics companies, computer software companies and money
center banks. Currently, the Fortis S&P 500 Index Portfolio holds all 500 stocks
in the S&P 500 in direct proportion to their weight in the Index.
 
OUTLOOK
 
As a portfolio that mirrors the holdings of an existing stock index, we will
continue to make the appropriate changes in accordance with the portfolio's
investment objective.

FORTIS SERIES FUND: BLUE CHIP STOCK PORTFOLIO
(SUBADVISED BY T. ROWE PRICE)
 
THE MONEY MANAGERS FOR THIS PORTFOLIO TARGET "BLUE CHIP" COMPANIES WITH LEADING
MARKET POSITIONS, SEASONED MANAGEMENTS 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.
 
REVIEW
 
The Blue Chip Stock Portfolio recognized its first eight months as part of the
Fortis Series Fund with a strong, positive performance return of 16.24 percent.
In fact, following stellar gains in 1995, the U.S. stock market surprised many
investors by advancing steadily through 1996 to mark one of the best two-year
performance periods on record. We remain cautiously optimistic that many of the
factors that have provided a strong environment for stocks will continue;
specifically, favorable inflation and interest rates, mutual fund inflows and
corporate earnings.
 
Risks that could dampen this outlook include the inconsistent economic
performance of many key trading partners, such as Japan and several European
economies, including Germany. More consistent performance of these economies is
needed for continued strong earnings growth at many U.S. multinational
companies. However, a strong synchronized boom in major world economies would
probably be a major negative for inflation, interest rates and, ultimately,
stock values.
 
Although your portfolio has less exposure to the technology market than the
average growth fund, our technology holdings performed very well. Financial
stocks also performed well, and we discovered some sound investment ideas in the
struggling retail sector. For example, Eckerd (a drug store holding) saw a boost
in its stock price when J.C. Penney's purchased the company. And the supermarket
giant, Safeway, also contributed positively to performance.
 
OUTLOOK
 
Stock values remain expensive, and we are wary of the strong results generated
by the market for two consecutive years. However, we realize that sound
investing must be driven by the outlook for the general investment environment
and future company earnings. Considering these factors, we believe the outlook
for U.S. stocks remains favorable.
 
We continue to target holdings that we believe are generally "all-season" growth
companies -- they can generate earnings growth regardless of the economic or
interest rate environment. As always, we strive to seek out blue chip companies
with leading market positions, seasoned management and strong financial
fundamentals, as we continue to believe they will provide superior investment
results.

FORTIS SERIES FUND: GLOBAL GROWTH PORTFOLIO
 
SLIGHTLY MORE AGGRESSIVE GROWTH INVESTORS WHO WANT TO DIVERSIFY AND EXPAND THEIR
HORIZONS BEYOND THE UNITED STATES MAY WANT TO CONSIDER THIS HIGHLY DIVERSIFIED
PORTFOLIO.
 
REVIEW
 
As a global portfolio, the Global Growth Series has the flexibility to invest in
a variety of stock markets around the world, including the United States. This
is a highly diversified portfolio with 117 holdings in 29 different nations. Our
investment focus is on companies with strong market positions and superior
growth prospects relative to the respective local economy.
 
The positive 19.10 percent performance of the Global Growth Series over the past
year can be attributed to favorable stock selection and a meaningful asset
weighting in the United States. In comparison, the Morgan Stanley Capital
International (MSCI) World Index, the portfolio's benchmark, realized a 14.00
percent return. Over the past several years, the portfolio has been
underweighted in markets such as Japan, which has significantly underperformed
the World Index. When researching potential investments, we look for companies
with a focused growth strategy, a strong management team, and the ability to
finance future growth. We also look for companies that tend to dominate their
respective market or industry. We have found that companies with these
characteristics tend to achieve superior returns for shareholders.
 
Through a global approach to growth investing, we are able to expose the
investor to the world's most dynamic growth segments. At the same time, global
investing provides greater diversification, which can help to reduce the
volatility traditionally associated with equity investing. Our approach at
Fortis has traditionally focused on mid-sized companies with superior growth
prospects. During 1996 these types of companies performed strongly during the
first half of the year. During the second half of 1996, these stocks tended to
lag the broader market averages, which are dominated by larger, "blue chip"
companies.
 
OUTLOOK
 
We are hopeful that investor focus will again return to companies with superior
growth prospects such as those held in the Global Growth Portfolio. Longer term,
the prospects for global investing remain quite favorable. The relatively poor
performance of the Japanese market, since 1989, has been more than offset by
stellar returns from the U.S. Our approach to global investing exposes investors
to all of the major markets and allows a greater degree of flexibility, which is
important with our high-growth investment style. Over the past year we have
broadened our diversification by adding to the number of holdings in the
portfolio. This has been done in an effort to limit the amount of
company-specific risk in the portfolio.

FORTIS SERIES FUND: GROWTH STOCK PORTFOLIO
 
THIS PORTFOLIO IS DESIGNED FOR INVESTORS WHO SEEK REWARD POTENTIAL ENTIRELY
THROUGH U.S. STOCKS. IT INVESTS IN MEDIUM-SIZED GROWTH COMPANIES THAT HAVE MOVED
BEYOND THE VENTURE STAGE.
 
REVIEW
 
The positive performance of the Growth Stock Portfolio in 1996 of 16.41 percent
was largely attributable to the portfolio's holdings of technology stocks, which
represented more than one-third of its assets during the year. Also making
positive contributions were selected holdings in the healthcare, financial
services and energy areas. Underlying the increase in the value of the
portfolio, of course, was the very strong advance exhibited by the overall stock
market, as represented by the major indices, such as the Standard & Poor's 500
Stock Index and the Dow Jones Industrial Average, of 22.98 percent and 29.49
percent, respectively.
 
The fact that the portfolio's gain was somewhat less than that of the major
indices is a result of two factors. First, while the Growth Portfolio invests
mainly in mid-sized companies, the market's leadership in 1996 was clearly among
the large, multi-national companies; and, second, small and mid-sized growth
stocks came under a great deal of selling pressure late in the year, erasing a
portion of the gains made in the first 11 months. The recovery in most of these
stocks early in 1997 would seem to imply that the selling was not done for
reasons to do with company fundamentals.
 
OUTLOOK
 
Our outlook for 1997 reflects the view that economic and financial market
fundamentals will be similar to those experienced in 1996. Specifically, that
means an economy that is growing but not at an exuberant rate, inflation that
can best be described as benign, and interest rates that should be contained
within the range traced over the last several months.
 
As the economy slows, we must concentrate on companies that are able to sustain
growth of their revenues. As a result, the portfolio continues to contain a
significant number of companies arrayed across a wide range of technologies.
Surveys of U.S. companies show an intention to expand the rate of spending on
technology, and the growth rate of such spending by foreign corporations is
significantly greater yet.
 
Other areas of the portfolio include low-cost providers of telecommunication
services competing against the major local exchange and long-distance companies;
companies providing oil and gas production equipment and services as production
companies strive to meet the needs of a growing global economy; healthcare
products and provider services in the struggle to contain the rising cost of
care; providers of financial products and services to allow individuals to plan
for the major financial requirements of their lives; and companies taking on
outsourcing responsibilities for a wide range of corporate functions as
companies continue to look for ways to lower costs of their products and
services in a highly competitive global environment.

INVESTING OFTEN SELECT THIS PORTFOLIO TO DIVERSIFY AN ESTABLISHED INVESTMENT
STRATEGY. IT FOCUSES EXCLUSIVELY ON GROWTH COMPANY STOCKS OUTSIDE OF THE UNITED
STATES.
 
REVIEW
 
The International Stock Portfolio, continuing to be propelled by strong stock
holdings, finished the year by outperforming the Morgan Stanley Capital
International Europe Asia Far East (MSCI EAFE) Index 14.02 percent to 6.64
percent. In fact, the fourth quarter provided a fitting end to another strong
year as several international equity markets reached record highs. Although U.S.
market performance captured much of the headlines during the year, European
equities rivaled its performance. In Japan, the market closed at its year low
after reaching a four-year high in June.
 
In 1996, investors witnessed a pivotal year for value creation by international
companies. The "shareholder value" focus started in the U.S. is quickly being
adopted in Europe and slowly in Japan. Investing in companies taking concrete
steps in line with the interests of stockholders was a major driver of the
portfolio's outperformance in 1996.
 
Specifically, European pharmaceutical companies continued to unlock value during
the fourth quarter, and the consolidation of European banking, utility and
telecommunications industries further evidenced the growing commitment to
creating shareholder value.
 
In Japan, despite good company results a weak Japanese business outlook survey
dragged its market down for the quarter and the entire year. Further behind in
its restructuring curve, Japan's slow economy and austere government programs
make stock picking in Japan essential. Companies that face their problems and
make changes will continue to profit, especially if the Japanese economy
struggles. This year was a perfect example as Japanese stock selection (Honda
and Toyota, for example) was a large contributor to outperformance of the
portfolio in 1996.
 
OUTLOOK
 
Looking ahead, global investors should be encouraged by attractive valuations
and by the concrete steps international companies are taking to improve their
return on capital and lower their cost of capital. Other important issues to
watch in 1997 include the development of a common European currency (EMU),
Japanese banks' willingness to write-off their bad debts, Hong Kong's transition
to China, and the value of the U.S. dollar.
 
It's important to note that many of the same forces that drove U.S. equity
returns in the past few years are now in place in foreign markets. Improving
global competitiveness, better corporate returns, declining interest rates,
cheaper foreign valuations, and a new equity culture bodes well for
international equity outperformance in the future through value stock selection.

FORTIS SERIES FUND: AGGRESSIVE GROWTH PORTFOLIO
DESIGNED ESPECIALLY FOR THE MOST AGGRESSIVE, LONG-TERM INVESTOR WHO BELIEVES IN
THE ENTREPRENEURIAL OPPORTUNITIES OF AMERICA. THIS PORTFOLIO INVESTS IN SMALLER,
EMERGING GROWTH COMPANIES THAT HAVE HIGH UNIT GROWTH RATES FOR THEIR PRODUCTS OR
SERVICES.
REVIEW
As we had suggested, 1996 was characterized by volatile performance. The
portfolio had strong performance through mid-May, followed by significant
fluctuations, both up and down. While the portfolio did provide a positive 7.6
percent return for the year, it was below that of the major market averages.
Most of our largest holdings continued to show very strong fundamentals and high
rates of earnings growth; however, investors' preference moved toward
larger-size and safety, bringing down valuations on smaller, high-growth
companies. To lessen risk and remain well-diversified, the portfolio increased
the number of holdings, thereby lowering the average size of positions.
OUTLOOK
Looking ahead, we continue to focus on quality, emerging high-growth companies
with a track record of success, and we believe the market will reward this type
of performance in the future.
Historically, investing in smaller companies can be more volatile over the short
term as a result of their higher relative valuations. We expect this tendency to
continue in 1997. It is our belief that investors with patience and a longer
time horizon can benefit from volatility and may be rewarded by the capital
appreciation of the leading growth companies of the future.

Notes to Financial Statements

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: The fund is an open-end
   management investment company which currently is comprised of fifteen
   separate investment portfolios and series of capital stock: Money Market
   Series, U.S. Government Securities Series, Diversified Income Series, High
   Yield Series, Asset Allocation Series, Global Asset Allocation Series, Value
   Series, Growth & Income Series, S & P 500 Index Series, Blue Chip Stock
   Series, Global Growth Series, Growth Stock Series, International 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.
 
   - The objective of the "U.S. Government Securities Series" is a high level of
     current income 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 a high level of current
     income by investing primarily in a diversified portfolio of government
     securities and investment grade corporate bonds.
 
   - The objective 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 through
     current income and capital appreciation by investing primarily in
     high-yield, high-risk fixed-income 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 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 "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
     "value" philosophy.
 
   - The objective of the "Growth & Income Series" are capital appreciation and
     current income, which such Series 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 return of
     the Standard & Poor's 500 Composite Stock Price Index (the "S & P 500
     Index" or the "Index") primarily through investments in equity securities.
 
   - The objective of the "Blue Chip Stock Series" is to provide 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 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 primary objective of the "Growth Stock Series" is short and long-term
     capital appreciation. The Series will seek to meet these objectives by
     investing primarily in common stocks and securities convertible into common
     stocks.
 
   - 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 "Aggressive Growth Series" is maximum 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. An investment in
   the Money Market Series is neither insured nor guaranteed by the U.S.
   Government.
 
   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 Value Series, S & P 500 Index Series, and Blue Chip Stock
   Series was March 28, 1996, and the commencement of operations was May 1,
   1996.
 
   The significant accounting policies followed by the Funds are summarized as
   follows:
 
   SECURITY VALUATION: Investments in securities traded on U.S. or foreign
   securities exchanges 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. 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.
 
   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,
 
                                                                              73

- --------------------------------------------------------------------------------
   assets with a market value equal to the amount of its purchase commitments.
   As of December 31, 1996 none of the portfolios had outstanding when-issued or
   forward commitments.
 
   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 closing 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 dates on securities transactions, and other translation
   gains or losses on dividends, interest income and foreign withholding taxes.
   Global Bond Series, High Yield Series, Global Asset Allocation Series, Blue
   Chip Stock Series, Global Growth Series, International Stock Series, and
   Aggressive Growth Series may enter into forward foreign currency exchange
   contracts for operational purposes and to attempt to minimize the risk from
   adverse exchange rate fluctuations. Global Bond Series, Global Asset
   Allocation Series and International Stock Series may also enter into
   speculative forward contracts. The net U.S. dollar value of foreign currency
   underlying all contractual commitments held by the fund and the resulting
   unrealized appreciation or depreciation are determined using foreign currency
   exchange rates from an independent pricing service. The fund 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. For financial reporting purposes each portfolio
   amortizes bond premium , market discount and original issue discount. For the
   year ended December 31, 1996, the cost of purchases and proceeds from sales
   of securities for Money Market Series were $321,445,992 and $303,052,167,
   respectively. The cost of purchases and proceeds from sales of securities
   (other than short-term securities) for the other portfolios were as follows:

   In the Global Asset Allocation Series for the period from January 2, 1996 to
   December 31, 1996, brokerage commissions paid to an affiliated broker
   amounted to $2,008.
 
   LENDING OF PORTFOLIO SECURITIES: At December 31, 1996, securities valued at
   $77,268,169 were on loan to brokers from Global Growth Series. For
   collateral, the portfolio's custodian received $79,685,151 in cash which is
   maintained in a separate account and invested by the custodian in short-term
   investment vehicles. Fee income from securities lending amounted to $93,561
   for the year ended December 31, 1996 for Global Growth Series. The risks to
   the portfolio 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.
 
   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. For tax purposes, each portfolio is a single taxable entity.
 
   On a calendar year basis, each portfolio intends to distribute substantially
   all of its net investment income and realized gains, if any, to avoid payment
   of federal excise taxes.
 
   Net investment income and net realized gains differ for financial statement
   and tax purposes primarily because of the recognition of realized gain (loss)
   from forgein currency transactions as ordinary income (loss) for tax purposes
   and the deferral of "wash sale" losses for tax purposes. The character of
   distributions made during the year from net investment income or net realized
   gains may also differ from it's ultimate characterization for federal income
   tax purposes.
 
   On the Statement of Assets and Liabilities, due to permanent book-to-tax
   differences, reclassification on adjustments in the following amounts have
   been made to increase (decrease) accumulated net realized gain (loss) with an
   offsetting increase (decrease) to undistributed net investment income.

</TABLE>
 
   In addition, the Money Market Series, due to permanent book-to-tax
   differences, accumulated net realized loss decreased by $20,625, which
   resulted in a reclassification adjustment to decrease paid-in-capital by
   $20,625.
 
   For federal income tax purposes the portfolios had the following capital loss
   carryovers at December 31, 1996, which, if not offset by subsequent
 
74

- --------------------------------------------------------------------------------
   capital gains, will expire in 1997 through 2005. 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.

   ILLIQUID SECURITIES: At December 31, 1996, investments in securities for the
   funds included issues that are illiquid. Money Market Series, U.S. Government
   Series, Diversified Income Series, Asset Allocation Series, and Growth Series
   currently limit investments in illiquid securities to 5% of total assets;
   Global Growth Series to 10% of total assets; Global Bond Series, High Yield
   Series, Global Asset Allocation Series, Growth and Income Series,
   International Stock Series, Aggressive Growth Series, Value Series, S & P 500
   Series, and Blue Chip Stock Series to 15%, of net assets, at market value, at
   date of purchase. The aggregate values of such securities at December 31,
   1996 were $2,486,550 Money Market Series; $1,137,282 Diversified Income
   Series; $3,256,511 Asset Allocation Series; $5,456,325 High Yield Series;
   $11,911,318 Global Growth Series, which represents 4.0%, 1.08%, .82%, 12.81%,
   3.72% of net assets, respectively. 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 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.
 
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:

4. FUTURES TRANSACTIONS: The Fund may invest in financial futures contracts in
   order to gain exposure to or protect against changes in the market. The Fund
   is exposed to market risk as a result of changes in the value of the
   underlying financial instruments (see the Notes to Schedule of Investments).
   Investment in financial futures require the Fund 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 Fund reconizes 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, 1996 and their related
   unrealized market appreciation are set forth in the Notes to Schedule of
   Investments.

request confirmations from brokers, and where replies are not received, we carry

assessing the accounting principles used and significant estimates made by
