HOW TO USE THIS REPORT
 
Some of our clients prefer a narrative account of their Advantus Series Fund
investments while other clients prefer full financial statements. This report is
designed to meet both preferences.
 
    For a narrative account of each Portfolio's performance, investment
strategies and holdings by the Portfolio Manager, refer to the front section of
the report. Comprehensive investment holdings, market values and financial
reports begin on page 41.
 
    Performance charts graphically compare each Portfolio's performance with
select investment indices and other benchmarks. This comparison provides you
with more information about your investments.
 
    The charts are useful because they illustrate performance over the same time
frame and over a long period. There are limitations, however. An index may
reflect the performance of securities that the Portfolio may not hold. Also, the
index does not deduct investment advisory fees and other fund expenses--whereas
your Portfolio does. Individuals cannot buy even 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(s) in the Advantus Series Fund. Your Ascend Sales
Representative, who understands your personal financial situation, can best
explain the features of your investment and how they apply to your financial
needs.

    Historical results are not an indication of future performance. Investment
returns on principal values will fluctuate so that shares upon redemption may be
worth more or less than their original cost. Performance figures of the Fund do
not reflect charges pursuant to the terms of the variable life insurance
policies and variable annuity contracts funded by separate accounts that invest
in the Fund's shares. When such charges are deducted, actual investment
performance in a variable policy or contract will be lower. Please refer to the
individual Portfolio reviews for information regarding the standardized

LETTER FROM THE PRESIDENT
 
                                                                   [PHOTO]
 
Dear Shareholders:
 
Throughout 1998, the global economy was steeped in volatility, uncertainty,
and--in some cases--utter chaos. Some of the bleak economic realities that
permeated the global economy throughout most of the year brightened in the
fourth quarter. The U.S. economy and markets remained strong despite periodic
volatility and several out-of-the-ordinary events.
 
For most of the year, Asia was mired in a world of economic hurt. Asian
countries suffered from a glut of economic ills that devalued currencies and
shook businesses and governments. Even now, the Japanese economy continues to
spiral downward. Similarly, a bleak economic outlook looms over Russia, whose
economy remains in default, and Brazil, who continues to resist the
International Monetary Fund's demands for economic reforms and deficit
reductions.
 
To hold the line against continued global economic ills, central banks based in
the United States and Europe pumped tremendous liquidity into world markets.
This strategy drove down interest rates and calmed some erratic world markets.
Keep in mind that the problems did not disappear, but the swift and concerted
efforts of the United States and several Western European countries and their
central banks averted increasing global problems.
 
We believe the United States' economy remains very strong. The fourth quarter
ending December 31, 1998 marked the longest period of economic expansion in our
country's history, 28 quarters (as measured by positive GDP). Low inflation
continues, as well. The Federal Reserve has been vigilant and deserves much
credit for our country's excellent economic status. The Federal Reserve's
proactive, accommodating stance has bolstered confidence in our economy to
investors both here and abroad.
 
Year ending December 31, 1998 marked four years of double-digit returns in the
major stock market indices. We finished 1998 with new highs in the large cap
indices and with investment inflows returning to the market--all on the heels of
a litany of serious issues, including presidential impeachment. The bond market
was strong and delivered high single-digit returns for much of the year, but was
fraught with volatility. Despite the bull market in bonds, U.S. Treasuries led
the way due to the "flight to quality" caused by investors seeking safe
investment haven away from Asian and other falling markets. In the third
quarter, the corporate bonds and mortgage securities had their worst relative
performance period in over a decade. The tables turned quickly in the fourth
quarter, due largely to the Federal Reserve's cuts to short-term interest rates
and a greater confidence in the state of the global economy. The flight to
quality seemed to change directions, and many investors moved away from
Treasuries and back into the corporate and mortgage realm.
 
Looking forward, we expect economic and political tumult in Russia, parts of
Asia, Japan, and Latin America, particularly Brazil, will continue. In Asia, we
believe a slow recovery is underway and will likely progress throughout 1999;
the exception to recovery is Japan. On the European continent, early indications
in 1999 favor the euro. We anticipate that countries linked by the euro will
likely benefit. Producers can sell efficiently across borders without the
expense and burden of currency exchanges. In the U.S., we expect strong economic
conditions to continue. Growth will likely slow, but it is likely to continue,
and we believe inflation is likely to stay at a low level with interest rates
dropping even more. We see the long-term fundamentals for the U.S. stock and
bond markets remaining positive.
 
In 1998, some investments delivered stellar results while others lagged. The
volatility experienced in both the stock market and bond market in 1998
illustrates the importance of maintaining a diversified portfolio. Taking a
closer look at how you have allocated your investment is both appropriate and
prudent. We recommend that you work with your Ascend Financial Services
investment professional to review your financial goals and, if necessary,
rebalance your assets appropriately.
 
Sincerely,
 
/s/ William N. Westhoff
 
William N. Westhoff, President
Advantus Series Fund, Inc.

GROWTH PORTFOLIO
PERFORMANCE UPDATE
THOMAS GUNDERSON, CFA
PORTFOLIO MANAGER
 
  [PHOTO]
            The Growth
            Portfolio seeks
            the long-term
            accumulation of
capital, with current income
as a secondary objective. It
invests primarily in common
stocks and other equity
securities.
PERFORMANCE
The Growth Portfolio generated a total return of 34.70 percent* for the year
ended December 31, 1998. In comparison, the Russell 1000 Growth Index** returned
38.72 percent for the same period.
PERFORMANCE ANALYSIS
We believe the "large capitalization growth stocks" were one of the best places
to be in 1998 as their performance far exceeded the rest of the U.S. equity
markets. Within this class of stocks, it was the very largest companies,
especially in the technology sector, that provided the biggest gains. Stocks
like Microsoft, Lucent, Wal-Mart, Cisco Systems, Home Depot all posted 1998
gains over 100 percent.*
    In the uncertain and volatile market of 1998, investors placed a greater and
greater premium on companies where the earnings growth visibility was high and
the level of company volatility was low. As a result, the valuations on these
types of very large companies expanded to levels not seen in recent history,
both on an absolute and relative (to the broader market) basis.
    The Technology Sector was by far the strongest sector of the market for
1998. Internet spending helped propel the growth along with very strong growth
in the telecommunications equipment industry. The Portfolio had meaningful
participation in the Technology Sector with stocks such as Lucent, Cisco
Systems, Microsoft and MCI/Worldcom all posting excellent performance. A lack of
investing in "pure" internet stocks such as America Online, Yahoo, etc. was one
of the primary reasons the technology stocks in this Portfolio did not keep pace
with those of the index.
    Healthcare was the second highest performing sector. New and better drugs
selling at higher prices into a fast growing demographic allowed the
Pharmaceutical companies to lead the way in the Health Sector. Stocks in the
Portfolio had meaningful participation in this sector as well, such as Pfizer,
Guidant, Merck, and Warner Lambert.
    Other stocks that had a meaningfully positive contribution to performance
were Safeway (food retailer), Tyco International (conglomerate), EMC Corp.
(computer data storage), Intel (semiconductors), and Carnival Cruise Line.
    The Consumer Staples lagged the overall market during 1998. Consumer Staples
stocks were hurt by slowing international demand, their primary growth market,
along with unfavorable currency swings. A clear example of this was Coca-Cola
Company where these factors caused earnings projections to be missed and the
stock price to end the year exactly where is started the year at $67. Owning
less in the Consumer Staples sector relative to the index helped the Portfolio.
    The successful investment process utilized by the Portfolio weeds out the
under performing companies whose operating results do not meet our expectations.
Over the past year the list of companies whose operating fundamentals did not
meet our expectations and thus were liquidated include Computer Associates
(software), ADC Telecommunications (telecom equipment), Safeskin (medical
supplies), CNF Transportation (shipping) and Tellabs (telecom equipment).
OUTLOOK
The long-term fundamentals for the U.S. stock market are still positive.
Industrialized countries around the world are suffering from slow economic
growth and over capacity. With global demand low and the ability to produce
high, inflation will likely remain benign. Commodity prices are falling and will
likely stay depressed until worldwide economic activity begins to strengthen.
Despite the global downturn, the U.S has been an island of prosperity in the
global marketplace. Strong domestic growth with low inflation and an
accommodative Federal Reserve has kept both stocks and bonds performing well.
The Federal Reserve made three swift 25 basis point cuts (.75 percent in total)
in the Fed Funds rates to help avoid a global financial crisis.
    The upcoming year will likely be filled with volatility, strong industry
rotation, and anticipation as we approach the "year 2000" issue. We will
continue to implement our disciplined methodology in managing the Portfolio by
investing in companies we believe are able to sustain above average earnings
growth through an economic cycle while quickly sifting out those who do not meet
our expectations. Performance for the year 1998 validates the success of this
strategy.

 *Historical performance is not an indication of future performance.
  Investment returns on principal values will fluctuate so that shares
  upon redemption may be worth more or less than their original cost.
  Performance figures of the Fund do not reflect charges pursuant to
  the terms of the variable life insurance policies and variable
  annuity contracts funded by separate accounts that invest in the

BOND PORTFOLIO
PERFORMANCE UPDATE
WAYNE SCHMIDT, CFA
PORTFOLIO MANAGER
  [PHOTO]   The Bond
            Portfolio seeks
            as high a level
            of long-term
total return as is consistent
with prudent investment risk.
Preservation of capital is a
secondary objective. The Bond
Portfolio invests in
long-term, fixed income, high
quality debt instruments.
PERFORMANCE
For the year ended December 31, 1998, the Bond Portfolio returned 6.08 percent.*
The Portfolio's benchmark, the Lehman Brothers Government Corporate Bond
Index,** returned 9.47 percent for the same period.
PERFORMANCE ANALYSIS
The past year, 1998, was a challenging year for fixed income investors, and
especially for corporate bond investors. At the beginning of the year, yields in
the U.S. Treasury market were attractive and there was a high degree of comfort
in the corporate bond market. With strong corporate earnings and a sound U.S.
economy, corporate bonds appeared fairly valued. As global events began to
unfold, investor sentiment swung heavily toward the safety of the U.S. Treasury
market. Russia defaulting on their debt, rumors of hedge funds collapsing, fear
of a bear market in stocks, global recession, low interest rates around the
world and the Federal Reserve reluctant to ease monetary policy made U.S.
Treasuries the only safe place to be. Interest rates plunged lower as liquidity
in corporate bonds and mortgage-backed securities disappeared. In the latter
part of the year, the Federal Reserve cut key short-term interest rates
aggressively, stocks rebounded to pre-crash highs, fears of a global meltdown
subsided and investors began a slow return to the corporate bond market.
    After the dust settled, the yield on the 30-year U.S. Treasury Bond
decreased 83 basis points to 5.09 percent. In the fourth quarter, 4.69 percent,
the lowest yield ever recorded on a 30-year U.S. Treasury Bond was reached.
Yields on intermediate maturity notes moved anywhere from 110 to 116 basis
points lower over the course of the year.
    Within the fixed income market there are three major sectors: government,
corporate and mortgage-backed securities. During the year, returns from
corporate bonds and mortgaged-backed securities suffered as investors sought
safety in U.S. Treasury securities. Corporate bond spreads hit their widest
level in this decade. Fear of buying risk assets reached its height just prior
to the Federal Reserve's quick and decisive action to ease monetary policy. An
accommodative Federal Reserve gave fixed income investors confidence to purchase
corporate bonds late in the year. The renewed buyer interest in this sector
caused spreads to move modestly tighter in the more liquid, higher credit
quality names. Although spreads tightened in the fourth quarter, they are still
wide based on historical levels.
    Our longer-term view on interest rates is positive. The fundamentals of the
fixed income market have pointed to lower interest rates for some time. To take
advantage of this outlook, the Portfolio duration has been kept longer than the
benchmark index (Lehman Brothers Government Corporate Index) over the course of
the year. This was a positive factor as interest rates declined.
    While the duration call was right, the decision to emphasize corporate bonds
negatively impacted performance. The root cause of this year's below market
performance has the overweighing of the spread sectors, especially the triple
B-rated corporate securities which because of unusual market conditions, proved
to be less liquid at that point in time. Nineteen ninety-eight marked the worst
relative performance of corporate bonds in this decade. While the ride to wider
spreads (lower prices) was painful, owning corporate bonds through the cycle
will reward longer-term investors. Entering 1999, corporate bond spreads are at
the most attractive levels since the 1990 recession.
OUTLOOK
Our top-down view calls for moderately lower interest rates and improvement in
the spread sectors, corporate bonds and mortgage-backed securities. The duration
of the Portfolio will be kept longer than the benchmark index reflecting our
positive outlook on interest rates. The over allocation to spread product
(non-Treasury) will continue as spreads are still near their cyclical wide. In
the corporate bond market, emphasis will be on the higher quality, more liquid
names. As conditions improve, there will be an opportunity to selectively move
into some BBB-rated names.
    The long-term fundamentals for the U.S. bond market are still positive.
Industrialized countries around the world are suffering from slow economic
growth and over capacity. We anticipate that with global demand low and the
ability to produce high, inflation will likely remain benign. Commodity prices
are falling and will likely stay depressed until worldwide economic activity
begins to strengthen. Despite the global downturn, the U.S. has been an island
of prosperity in the global marketplace. Strong domestic growth with low
inflation and an accommodative Federal Reserve has kept both stocks and bonds
performing well. Since late September, the Federal Reserve made three swift 25
basis point cuts (.75 percent in total) in the Fed Funds rates to help avoid a
global financial crisis. From here, the Federal Reserve will be monitoring the
U.S. economy closely and will not ease further until there is hard evidence that
a domestic economic slowdown underway. Looking ahead to 1999, economic growth
will likely slow as global pressures finally reach the U.S. When this happens,
interest rates will likely move moderately lower and we anticipate that the
Federal Reserve would ease rates modestly to engineer another soft landing.

the preservation of capital.
It invests in short-term
money market instruments and
other debt securities that

VALUE OF $1.00 PER SHARE
PERFORMANCE
The Money Market Portfolio's total return for the year ended December 31, 1998
was 4.97 percent.* The three-month U.S. Treasury Bill returned 5.31 percent for
the same period.
PERFORMANCE ANALYSIS
The year just ended was an extremely tumultuous one in many respects, as a
number of watershed events profoundly impacted financial markets worldwide. The
most notable events included Russia's default on its debt; the near collapse of
Long Term Capital Management (one of the nation's largest hedge firms);
recession in Japan and financial crisis in several other Asian economies; the
collapse of oil and other commodity prices; and the major decline in U.S. stock
markets, fueled in part by the Russian payment default. Considering all that
occurred over the past year, it's really no surprise that risk premiums, or
spreads, on financial assets are wider now than a year ago.
    Throughout 1998, however, inflation was essentially benign. This fact,
coupled with a softer growth outlook in the U.S. and three interest rate cuts by
the Federal Reserve in response to several global crises, paved the way for
lower interest rates. Over the course of the year interest rates in the U.S.
declined meaningfully across the yield curve compared to year end 1997 levels.
The yield on the three-month U.S. Treasury Bill declined 88 basis points over
the year to yield just 4.46 percent at year end. This is still below the Fed
Funds rate, which is targeted at 4.75 percent.
    In response to investors' reaction to the global crises, the Federal Reserve
was forced into action in late September, lowering the Federal Funds rate by 25
basis points to 5.25 percent. During the fourth quarter the Federal Reserve
lowered the Federal Funds rate by 25 basis points on two additional occasions
(50 basis points in total, 75 basis points for the year) in an attempt to
restore liquidity to the financial markets and boost investor confidence.
    Despite the volatility that we continue to experience from quarter to
quarter and across different markets and sectors, high-quality U.S. corporate
commercial paper continues to offer excellent safety and liquidity. The
Portfolio's assets are invested in high quality corporate commercial paper
(i.e., commercial paper that is rated A-1 or higher by Standard and Poors and
P-1 by Moody's) and agency-backed obligations at year end.
    The Portfolio's holdings continue to be well diversified over a variety of
stable industries and do not include any holdings in the much more volatile bank
and brokerage sectors. Our goal has been to maintain or extend the average days
to maturity of the Portfolio and, to that end, the average days to maturity at
period end was 60 days, slightly longer than the money market fund industry
average. For the Portfolio, we will continue to purchase the highest quality
commercial paper and seek to maintain the average days to maturity in the
Portfolio in a range from 60 to 70 days.
OUTLOOK
With three separate 25 basis point cuts in the Federal Funds rate over a
seven-week period ending November 17, the Federal Reserve has successfully
restored liquidity to the markets and boosted investor confidence. However, as
confirmed by the minutes from the November 17 FOMC meeting, the Fed has now
shifted to a "neutral" position regarding interest rates from its previous bias
to ease interest rates. As a result, unless a major event occurs that has
negative global implications or until there are demonstrable signs that U.S.
economic activity has meaningfully slowed, we believe that the Federal Reserve
will likely be on hold for at least a few months relative to further interest
rate changes. Notwithstanding this belief, we maintain a bias toward slightly
lower interest rates over the next few months, particularly short-term interest
rates.

    The seven-day compound yield is computed by determining the net change in
the value of a hypothetical account having a balance of one share at the
beginning of a seven calendar day period, dividing that change by seven, adding
one to the quotient, raising the sum to the 365th power and subtracting one from
the result.

ASSET ALLOCATION PORTFOLIO
PERFORMANCE UPDATE
THOMAS GUNDERSON, CFA
PORTFOLIO MANAGER
 
  [PHOTO]
            The Asset
            Allocation
            Portfolio seeks
            as high a level
            of long-term
total rate of return as is
consistent with prudent
investment risk. It invests
in common stocks and other
equity securities, bonds and
money market instruments. The
mix of investments is varied
by the Portfolio's management
as economic conditions
indicate.
PERFORMANCE
The Asset Allocation Portfolio generated a total return of 23.65 percent* for
the year ended December 31, 1998. In comparison, the Russell 1000 Growth Index**
returned 38.72 percent, and the Lehman Brothers Aggregate Bond Index+ returned
8.69 percent for the same period. A blended index comprised of 60 percent
Russell 1000 Growth Index** and 40 percent Lehman Brothers Aggregate Bond Index+
returned 26.80 percent for the year ended December 31, 1998.
PERFORMANCE ANALYSIS
We believe the large capitalization growth stocks were one of the best places to
be in 1998 as their performance far exceeded the rest of the U.S. equity and
fixed income markets. Within this class of stocks, it was the very largest
companies, such as Microsoft, Lucent and Wal-Mart, that provided gains over 100
percent.*
    In the uncertain and volatile market of 1998, stock investors placed a
greater and greater premium on companies where the earnings growth visibility
was high and the level of company volatility was low. As a result, the
valuations on these types of very large companies expanded to levels not seen in
recent history, both on an absolute and relative (to the broader market) basis.
    Indeed, 1998 was a challenging year for fixed income investors, and
especially for corporate bond investors. At the beginning of the year, yields in
the U.S. Treasury market were attractive and there was a high degree of comfort
in the corporate bond market. With strong corporate earnings and a sound U.S.
economy corporate bonds appeared fairly valued. As global events began to
unfold, investor sentiment swung heavily toward the safety of the U.S. Treasury
market. Russia defaulting on its debt, the possible collapse of sizable hedge
funds, fear of a bear market in stocks, global recession, low interest rates
around the world and the Federal Reserve reluctant to ease monetary policy made
U.S. Treasuries the only safe place to be. Interest rates plunged lower as
liquidity in corporate bonds and mortgage-backed securities disappeared.
Corporate bond spreads hit their widest level in this decade. In the latter part
of the year, the Federal Reserve cut key short-term interest rates aggressively,
stocks rebounded to pre-crash highs, fears of a global meltdown subsided and
investors began a slow return to the corporate bond market.
    The Portfolio effectively managed its assets through the volatility and
posted an excellent year of performance as measured against other similar
balanced or asset allocation portfolios. The asset mix in this portfolio started
the year at 55 percent stocks, 35 percent bonds, and 10 percent cash. In
January, 5 percent was added to stocks of the "large capitalization growth"
variety, while in March and April another 5 percent was added to stocks
primarily in the "REIT" category, as they were significantly lagging the market
and provided an attractive current yield and total return. An additional 5
percent was added to stocks during the market sell off in August and September
as events provided a good buying opportunity. Stocks closed the year at 70
percent of the portfolio, with bonds at 28 percent with the remaining 2 percent
invested in short term money market securities.
    Technology was by far the strongest sector of the stock market for 1998.
Internet spending helped propel the growth along with very strong growth in the
telecommunications equipment industry. The Portfolio had meaningful
participation in the Technology Sector with stocks such as Lucent, Cisco
Systems, Microsoft and MCI/Worldcom all posting excellent performance.
Healthcare was the second highest performing sector. New and better drugs
selling at higher prices into a fast growing demographic allowed the
pharmaceutical companies to lead the way in the Health Sector. Stocks in the
Portfolio, such as Pfizer, Guidant and Merck, had meaningful participation in
this sector.
    REITS and Consumer Staples lagged the overall market during 1998. REITS
lagged the market for a variety of reasons including the expectations of slowing
earnings growth. Consumer Staples stocks were hurt by slowing international
demand, their primary growth market, along with unfavorable currency swings. A
clear example of this was Coca-Cola Company, where these factors caused earnings
projections to be missed and the stock price to end the year exactly where it
started the year at $67.
    Over the past year the list of companies whose operating fundamentals did
not meet our expectations and thus were liquidated include Computer Associates
(Software), ADC Telecommunications (telecom equipment), Safeskin, (medical
supplies), CNF Transportation (shipping), and Tellabs (telecom equipment).
OUTLOOK
The long-term fundamentals for the U.S. stock and bond market are still
positive. Industrialized countries around the world are suffering from slow
economic growth and over capacity. We anticipate that with global demand low and
the ability to produce high, inflation will remain benign. Commodity prices are
falling and will likely stay depressed until worldwide economic activity begins
to strengthen.
    The upcoming year will likely be filled with volatility, strong industry
rotation, and anticipation as we approach the "year 2000" issue. As always, we
will seek to position the portfolio to meaningfully participate in significant
market advances while protecting your capital during periods of market decline.

Lipper Analytical Service's U.S. Mortgage Fund Category,+ the Portfolio's peer
group, returned 5.80 percent for the same time period.
PERFORMANCE ANALYSIS
It certainly has been an interesting year. For the first seven months of the
year, the bond market traded in a relatively narrow range as investors watched
anxiously as many global markets either slowed or entered into a recession. By
the third quarter, it was apparent that the U.S. could no longer remain an oasis
of prosperity capable of functioning independently of world events. Sharp
declines in overseas markets and turmoil in the U.S. capital markets lead to a
massive "flight to quality" rally, driving yields on the ten-year treasury bond
below 4.20 percent, a full 1.0 percent below the previous generational low set
in October 1993. Mortgage rates followed treasury rates lower and produced a
powerful refinancing wave that helped push mortgage spreads (over treasuries)
out to levels not seen since 1986.
    We saw 1998 was the year to be in prepayment-protected securities and carry
more duration than the Index. In an effort to position the Portfolio along these
themes, we were underweight in new issue current coupon and premium coupon
mortgage pass-through securities. Better value was found in secondary issues and
issues not included in the Index but offering good prepayment stories. This
trade into more prepayment challenged securities served as a harbor against the
prepayment storm, but the price of admission was a willingness to accept less
liquidity. This was a fair trade given current market fundamentals and relative
pricing levels. To accomplish this value driven mission we increase our
ownership of commercial mortgage securities and other high quality
collaterialized mortgage obligations (CMOs) while focusing our ownership of
premium coupon securities in very seasoned issues.
    Likewise, we participated in several trades that allowed us to swap
prepayment risk for credit risk. While these were all investment grade
securities, our preference was to increase our ownership of AA-rated securities
given the historically narrow level of spreads between different rated classes.
Many of these nonagency mortgage securities continue to enjoy strong
fundamentals as seen by the high number of securities that either received
ratings upgrades or are currently candidates for an upgrade. Unfortunately, this
sector of the mortgage market experienced more than its share of spread widening
that came to define the fixed income markets during the second half of the year.
Even though these securities offered solid prepayment protection going into the
rally, their prices did not appreciate as much as one would have anticipated
given the change in the general level of interest rates. While some strategies
worked better than others did in this liquidity-driven environment, all these
activities allowed us to build upon an already broadly diversified portfolio of
mortgage securities, capable of delivering competitive performance in a more
holistic manner over the long term.
    The duration of the Portfolio ranged from 5 percent to 14 percent longer
than Lehman Brothers Mortgage-Backed Index** (approximately 2.2 years at
year-end) while the overall credit quality of the Portfolio remains very high at
AA2.
OUTLOOK
The Federal Reserve has clearly signaled that it is safe for investors to wade
back into mortgages and corporate markets. As investors once again embrace the
value-investing themes that drove the market prior to the third quarter of 1998,
we look forward to a period of strong relative performance from mortgages: The
sector is fundamentally cheap and in good technical shape.
    The mortgage market has already priced in some very aggressive prepayment
and recessionary assumptions. Unless rates rally by more than 50 basis points,
the fear of another refinancing peak appears to be overstated as prepayments are
likely to stabilize or trend lower. Likewise, non-agency mortgage securities
that are not subject to the same types of credit considerations as corporates
have widened as much as, or in some cases more, than corporates. Fortunately,
most of this spread widening appears to be due to liquidity considerations and
supply issues and not solely credit concerns, as housing fundamentals remain
very strong. Unless the economy enters a recession--which is NOT our
forecast--this market should benefit as spreads tighten. As of this writing,
mortgage securities have remained among the highest-yielding asset classes
available in the fixed income market.*

INDEX 500 PORTFOLIO
PERFORMANCE UPDATE
KEVIN ZWART
PORTFOLIO MANAGER
 
  [PHOTO]
            The Index 500
            Portfolio seeks
            investment
            results that
correspond generally to the
price and yield performance
of the common stocks included
in the Standard and Poor's
Corporation 500 Composite
Stock Index (S&P 500).+ It is
designed to provide an
economical and convenient
means of maintaining a broad
position in the equity market
as part of an overall
investment strategy.
PERFORMANCE
For the year ended December 31, 1998, the Index 500 Portfolio returned 27.99
percent.* This compares to the S&P 500 Index,** which earned 28.57 percent for
the same period.
PERFORMANCE ANALYSIS
Even though the year end return was in the top 20 of all time for the S&P 500
Index,** about 70 percent of the return was generated by the largest 50 stocks
in the index. The largest stocks have continued to outperform smaller stocks.
    The Technology sector has carried the index for the past year. In addition
to being the highest weighted sector in the index, it also returned 76.4 percent
for the year. Lucent and Microsoft were the two stocks with the largest
contribution to the index this year. Transportation stocks ended the year flat,
and the Basic Materials sector was the only sector in the red for the year,
owing much of its loss to an 8.4 percent decline in the chemicals segment.
OUTLOOK
Over the last five years the S&P 500 Index** has averaged a total return of over
20 percent. This has been the best five year period in over 70 years. While
money continues to flow into the markets it is difficult to see how long these
kind of increases can continue. Throughout 1999 it will be important for sectors
other than technology to increase performance. So we could likely continue
seeing the same kind of returns that we have grown used to since 1995.

CLARK WINSLOW, CFA
WINSLOW CAPITAL
MANAGEMENT
  [PHOTO]   The Capital
            Appreciation
            Portfolio seeks
            growth of
            capital.
Investments will be made
based upon their potential
for capital appreciation.
While Advantus Capital
Management, Inc. acts as
investment adviser for the
Portfolio, Winslow Capital
Management, Inc. provides
investment advice to the
Capital Appreciation
Portfolio under a subadvisory
agreement.
PERFORMANCE
For the year ended December 31, 1998, the Capital Appreciation Portfolio
returned 30.83 percent.* This compares with the S&P 500 Index,** which returned
28.57 percent, and the Russell 1000 Growth Index,+ which returned 38.72 percent
for the same period.
PERFORMANCE ANALYSIS
As we discussed in the mid-year summary, the largest market capitalization
companies outperformed the broad market. This bias persisted in the second half
of 1998. For the year ending December 31, 1998, the performance of the S&P 500
Index** was narrower than in all but one of the past ten years. The 20 largest
growth stocks now comprise over one third of the S&P 500 Index** market value,
slightly exceeding the peak in 1973. If you did not own a few select stocks, the
index was difficult to beat. For the last four quarters, the S&P 500 Index**
outperformed 86 percent of U.S. equity mutual fund managers.
    In addition to the equity market maintaining a narrow focus on market
capitalization, nearly half of the return in the large cap indices was accounted
for in megacap technology stocks. We are certainly believers in the Internet and
are convinced it will have an important impact on everyone's life and business.
However, when we look at the skyrocketing stock price relative to foreseeable
fundamentals, we are astounded.
    The investment philosophy implemented by Winslow Capital Management in the
Portfolio is based on the belief that investing in companies with persistent
earnings growth will provide superior results over the long term. Through
fundamental research of these companies, we identify stocks that are
attractively valued relative to their estimated future earnings growth. Mixing
several medium capitalization stocks with large cap growth issues enhances the
philosophy. This means that we generally will be underweighted in the very
largest, slower growing companies most of which have performed strongly in the
recent past.
    The best performing sectors in the Portfolio for 1998 were Consumer Services
and Technology. The best performing holdings in the Consumer Services sector
were Home Depot and Wal-Mart; both appreciated over 100 percent.* The average
consumer stock in the Portfolio advanced nearly 60 percent.* In addition, our
stock selection in the Consumer Services sector added value relative to the S&P
500 Index.** The strongest performing technology stock was Cisco Systems. It
gained 150 percent* for the year ending December 31, 1998. The average
technology holding in the Portfolio gained more than 59 percent.* Due to
excessive valuations, the Portfolio has only minor exposure to Internet Mania.
OUTLOOK
Although there are many risks to contend with--Brazil and Latin American
potential economic chaos, Asian/Japanese economic weakness, U.S. trade deficit,
Year 2000 computer uncertainties and the like, we believe the U.S. economy is
likely to produce moderate Gross Domestic Product growth in the 2 percent area
with negligible inflation. Profits are likely to be down a bit in the first half
of 1999 but will likely improve in the second half for some net growth for the
year.
    The stock market, in our view, consists of two parts--a relatively small
number of "anointed" stocks and "all others". The former seem overvalued
compared to the latter which particularly includes midcap stocks. We are
building our portfolios principally from "all other". With minimal earnings
growth in the economy and a record high price/earnings ratio, it seems more
likely the market indices--S&P 500 at 1270 and Dow Jones at 9550--will churn
around awhile with more volatility before achieving some potential net gain by
year end. The increase in worldwide liquidity is certainly benefiting financial
assets, but the opportunity for gain appears to be best in the "all other"
non-megacap stocks.
    Winslow Capital follows a fundamental "bottom up" investment process that
leads us to companies with consistent and sustainable earnings growth.
Above-average growth is a necessity, but valuation of the stock is also
important. These investment philosophy guidelines have led us to identify
opportunities in the Consumer Services, Technology and Healthcare sectors
heading into 1999.

INTERNATIONAL STOCK PORTFOLIO
PERFORMANCE UPDATE
GARY CLEMONS
TEMPLETON INVESTMENT
COUNSEL
  [PHOTO]   The International
            Stock Portfolio
            seeks long-term
capital growth. The Portfolio
will invest primarily in
common stocks of companies
and governments outside the
United States. While Advantus
Capital Management, Inc. acts
as investment adviser for the
portfolio, Templeton
Investment Counsel, Inc.
provides investment advice to
the International Stock
Portfolio under a subadvisory
agreement.
PERFORMANCE
During the 12 months under review, global financial markets experienced
unprecedented volatility and uncertainty. Japan continued its unending ability
to disappoint investors with their feeble attempt to stimulate their economy,
the Russian economy is on the verge of collapse and the infamous Asian contagion
revisited Latin America. Investors learned the negative implications of global
corporate interdependence, as the events in Asia, Latin America and Russia
resulted in economic slowdowns and expectations for weak global GDP growth in
1999. In this environment, the International Stock Portfolio returned 6.61
percent* for the year ended December 31, 1998, compared to the Morgan Stanley
Capital EAFE Index** return of 20.33 percent for the same period.
PERFORMANCE ANALYSIS
The Portfolio benefited from a high exposure to the solid performing European
markets, which represented approximately 61.6 percent of total assets as of the
end of the period. The Portfolio benefited from a high weighting, of
approximately 9 percent, in the strong performing market of France, which
appreciated 42.1 percent* during the period. Interest rate convergence in
preparation for the EMU led to lower rates in several nations fueling the
markets rise. European financial equities were among the Portfolio's top
performers during the period, including French bank Banque National de Paris
(BNP), French Financial services company Axa and Dutch insurer Aegon which
advanced 56.5 percent,* 89.5 percent* and 184 percent,* respectively.
    The Latin American markets performed poorly during 1998 with many markets
falling excess of 30 percent. With approximately 7.5 percent of the Portfolio
assets in Latin American equities, performance was adversely impacted. Brazilian
was most detrimental to performance with our two holdings, Telebras and
Petrobras falling 77.25 percent* and 50.5 percent,* respectively. We view the
recent downturn in Latin equities as a short-term phenomenon, and view it as an
opportunity to find investment values throughout the region. We will continue to
devote attention toward discovering quality investments in the Latin American
Region.
OUTLOOK
Market weakness during the first half of the year created buying opportunities
in Asia, which we capitalized upon, increasing our Asian exposure to 10.9
percent of total assets, with the majority invested in Hong Kong. Although Japan
continues to falter we are starting to see signs of positive change. Small steps
by the government, such as allowing insolvent banks to fail, bode well for
future restructuring throughout Japan. We expect that our Asian exposure will
increase the coming year with Japan being a country offering some opportunity.

SMALL COMPANY PORTFOLIO
PERFORMANCE UPDATE
JIM TATERA, CFA
CHIEF EQUITY PORTFOLIO
MANAGER
 
  [PHOTO]
            The Small Company
            Portfolio seeks
            long-term
accumulation of capital. It
invests primarily in common
stocks of small companies,
defined in terms of either
market capitalization or
gross revenues that are less
than $1.5 billion.
Typically, at least 65
percent of the portfolio will
be invested in stocks of
small companies. In addition,
we will buy stocks of larger
companies that we feel are
growing significantly faster
than the market overall.
PERFORMANCE
The Small Company Portfolio returned 1.27 percent* for the year ended December
31, 1998. The Portfolio's benchmark, the Russell 2000 Growth Index** returned
1.24 percent for the same period. While small-cap stocks continued to lag large
cap throughout the year, the Portfolio outperformed its benchmark.
PERFORMANCE ANALYSIS
The equity markets were both volatile and narrow in 1998. In many respects, the
past year reminds me of a roller coaster with all its ups and downs and many
turns. It is no wonder the market and investors have felt whipped around at
times. The list of events that caused these feelings would include worldwide
economic turmoil, U.S. recession fears, a hedge fund meltdown and Federal
Reserve interest rate cuts.
    Driven by investors' needs for liquidity and the perceptions of earnings
certainty (i.e.: safety) large cap stocks outperformed small cap despite the
fact that earnings growth among smaller companies has, in recent quarters, been
greater than that of the larger companies. Also, despite strong earnings for
many of our companies, liquidity concerns drove small cap prices down numerous
times throughout the year. Many high quality, small cap growth companies have
been undeservedly priced down due to this continued bias toward larger
companies. As always we used these opportunities to add to our favorite
companies at cheap valuations. Overall, the Portfolio's holdings are growing
their earnings at over 30 percent per year in an environment where overall
corporate profits in the U. S. have weakened. Our objective has always been to
invest in companies with strong operating momentum and outstanding management.
In other words, we try to identify those companies with strong management teams,
which can grow the company into something special.
    Despite a difficult environment for retail and apparel, the Portfolio had
two significant contributors, Tropical Sportswear (men's apparel) and
Abercrombie & Fitch (specialty retailer). Both are executing their game plans
better than the competition and taking advantage of opportunities to expand
their businesses in very profitable ways. For example, Tropical Sportswear
acquired the Farah brand and incorporated it into their focused manufacturing
and distribution systems. This allowed them to expand their strong relationships
with key retailers like Wal-Mart that will substantially enhance growth
opportunities and profitability for Tropical Sportswear. Abercrombie & Fitch,
which focuses on young adult men and women, is capitalizing on the strength of
this segment and especially their lifestyle brand image, which targets a very
specific market yet also appeals to a broad group of customers. Their recent
expansion into children's stores has started off strong and will be another
growth leg for the company.
    CKS Group, which advanced nearly 150 percent* for the year, benefited from
the development of the Internet as it designs and implements Internet home pages
and then supplements this development with marketing services. It is the perfect
combination of services for companies that will utilize the Internet as a
distribution channel. CKS Group merged with USWeb late in the year to create the
largest and most diversified Internet development/marketing company in the
country.
    NCO Group, which provides collection services to a wide array of businesses
and government agencies, was another stock contributing to the Portfolio's
performance, returning nearly 75 percent* for the year. NCO Group had made a
number of acquisitions in the past year to become the dominant collection
company. It aims to ultimately become a full cycle receivables company that will
be able to handle a company's receivables from billing to collection. The
company's revenues increased by 99 percent* in the past 12 months with earnings
advancing 55 percent.*
    Other service-oriented companies which were outstanding performers for the
Portfolio, included Acxiom Corp, which provides direct marketing services and
data to businesses. Another, United Rentals, has become the key consolidator in
the rental services industry. Both companies had significant revenue and
earnings growth.
    Among the successes there were also disappointments. Two stocks that fell
short of our expectations were Stage Stores and Fairfield Communities. Stage
Stores is a department store retailer in small towns in the central and south
central parts of the country, which was impacted negatively by the adverse
weather conditions early in the year and ultimately, the drought experienced in
many markets they serve. Fairfield Communities, which markets vacation
properties and manages resort properties, also had difficulty throughout the
year due to the poor performance of an acquisition that took longer to turn
around than expected.
OUTLOOK
We believe the relative under performance of small companies and the extreme
volatility of the overall market has created tremendous opportunities in small
growth companies. Valuations continue to be near record low levels even after
the outstanding fourth quarter advance in the Portfolio.
    With uncertainty looming regarding President Clinton's impeachment, the Euro
debut and Year 2000 issues, 1999 shapes up as a potentially volatile period. As
always, we continue to focus on the ultimate drivers
 
                                       20
<PAGE>
of stock prices, namely, interest rates and corporate earnings. Interest rates
appear to be sustaining their low levels and stable trends while corporate
profits continue to be mixed. Our research efforts focus on the fundamental
trends in revenues and earnings growth. We strive to find those companies with
superior growth opportunities independent of specific economic events. We remain
confident in our abilities to uncover such companies and that the current
portfolio is positioned likewise. Finally, we would like to thank you for your
continued support and investment in the Small Company Portfolio.

 *Historical performance is not an indication of future performance. Investment
  returns on principal values will fluctuate so that shares upon redemption may
  be worth more or less than their original cost. Performance figures of the
  Fund do not reflect charges pursuant to the terms of the variable life
  insurance policies and variable annuity contracts funded by separate accounts
  that invest in the Fund's shares. When such charges are deducted, actual
  investment performance in a variable policy or contract will be lower.

PERFORMANCE ANALYSIS
Our investment activities continue to focus on tracking performance of the
respective indices. Over the long run, by selectively using Government Agency
securities in concert with U.S. Treasury securities, the Portfolios each
benefited from enhanced diversification and also from the receipt of additional
income (over that of U.S Treasury securities). However, in our pursuit to reap
the benefits for this style, we can expect to encounter short periods of high
volatility, which can push yield spreads wider on Agency securities. This is
exactly the environment in which we operated in during the second half of the
year, as Treasury returns led all fixed-income sectors higher. Agency securities
are now priced at extremely attractive levels. Therefore, we will
opportunistically look to increase our ownership of Agency securities.
    As time passes, the duration of each Portfolio continues to roll forward
toward its respective maturity. The effective duration of each Portfolio is as
follows:
 
<TABLE>
<S>                                                      <C>
Maturing Government Bond 2002 Portfolio................        3.70 years
Maturing Government Bond 2006 Portfolio................        7.60 years
Maturing Government Bond 2010 Portfolio................       11.40 years
</TABLE>
 
OUTLOOK
The secular bull market in interest rates that has graced the capital market
since the early 1980s, has most likely reached the mature phase in its cycle.
Going forward, returns are not likely to pierce double digits. Instead more
moderate returns should prevail as income, and not capital gains, drives returns
in the fixed income market.

VALUE STOCK PORTFOLIO
PERFORMANCE UPDATE
GARY ASTER, CFA
PORTFOLIO MANAGER
  [PHOTO]   The Value Stock
            Portfolio seeks
            long-term
accumulation of capital. The
Portfolio invests primarily
in equity securities of
companies, which, in the
opinion of the Adviser, have
market values, which appear
low relative to their
underlying value or future
growth potential.
PERFORMANCE
For the year ended December 31, 1998 the Value Stock Portfolio posted a total
return of 1.75 percent.* In comparison its benchmark, the Russell 1000 Value
Index** returned 15.63 percent and the S&P Barra Value Index+ returned 14.69
percent for the same period.
    In prior reporting periods, the S&P Barra Value Index+ was used as the
Portfolio's benchmark. The current benchmark, the Russell 1000 Value Index,**
better fits our stated investment objective than did the S&P Barra Value Index.+
The Portfolio's performance will be compared to the Russell 1000 Value Index**
going forward.
PERFORMANCE ANALYSIS
Most of the Portfolio's underperformance was recorded in the first six months of
the year as significant anticipated gains in certain commodity prices failed to
materialize. During the fourth quarter, we significantly changed the complexion
of the Portfolio. The weighted average market capitalization was increased
significantly, valuation measures such as price to earnings, price to book value
and price to cash flow were reduced and the dividend yield increased. Also,
investments, which assumed significant increases in the prices of certain
commodities such as oil, have been, for the most part, eliminated.
    The Communications, Consumer Staples, Capital Goods and Energy sectors
provided the best relative performance for the Portfolio during the period while
Financial, Basic Materials and Technology were the worst. Additions to the
Portfolio include Service Corp. International, the nation's largest operator of
funeral homes, Diebold, the largest producer of Automatic Teller Machines
(ATM's) and Union Pacific, the largest operator of rail systems in the U.S. Each
of these investments, while very different in the types of businesses they
operate, share several common characteristics: a significant price decline prior
to purchase and a commensurate shrinkage in valuation, sound fundamentals and,
in our opinion, modest risk.
OUTLOOK
The Portfolio will, no doubt, experience further changes in the future but at
the present time we are comfortable with the Portfolio's makeup. We will
continue to be diligent in our search for companies which meet our criteria for
investing and will not hesitate to add any which appear to have better prospects
than any of our current holdings. While it is sometimes tempting to participate
in current trends such as buying earnings momentum at any price, we remain
committed to our discipline of investing in companies which we believe are being
inefficiently priced in the market and have some downside protection in the
event of a market decline.

SMALL COMPANY VALUE PORTFOLIO
PERFORMANCE UPDATE
MARK HENNEMAN, CFA
PORTFOLIO MANAGER
   [PHOTO]   The Small
             Company
             Value
             Portfolio
             seeks the
long-term accumulation of
capital. It invests primarily
in the equity securities of
small companies, defined in
terms of market
capitalization and which
appear to have market values
that are low relative to
their underlying value or
future earnings and growth
potential.
PERFORMANCE
For the year ended December 31, 1998, the Small Company Value Portfolio returned
- -6.75 percent.* The Russell 2000 Value Index** returned -6.44 percent for the
same period. While showing respectable performance, small value stocks continue
to lag large capitalization stocks as investors are attracted to the superior
liquidity and stable earnings offered by these issues.
PERFORMANCE ANALYSIS
Small cap value stocks had a wild and largely unprofitable year. After posting
reasonable returns through the first two quarters, fears of an Asian economic
meltdown and its effect on domestic companies caused a steep correction in the
third quarter. Since early October, when the market bottomed, several important
things have happened that caused the market to recover: 1) the Fed cut interest
rates further, which increased confidence on the part of investors that the
United States would avoid a recession. 2) Asian and Latin American economies,
while not out of the woods, appear to have stabilized. 3) Fund flows into
domestic equity funds continues.
    While the Portfolio recovered significantly in the fourth quarter, the
rebound fell short of showing positive returns for the year. As the market
recovered, investors favored the largest capitalization companies because of
their liquidity and perceived lower risk. Once again in 1998, small
capitalization stocks underperformed large capitalization stocks
    The best performing sectors in the Portfolio were: Consumer Staples,
Consumer Cyclicals, Healthcare and Technology. Each of those sectors produced
positive double digit returns. The worst performing sectors were:
Transportation, Basic Materials and Finance. Each of those sectors were down
more than 20 percent.*
    Relative to the Russell 2000 Value Index,** the Portfolio's best performing
sectors were: Consumer Staples, Consumer Cyclicals, and Energy. In the case of
Energy, the return of the Portfolio was negative 8 percent,* but the Energy
stocks in the Russell 2000 Value Index** were down 44 percent. The Portfolio was
positioned with companies that either benefited from or were able to withstand a
difficult pricing environment for crude oil.
    Finance was the worst performing sector relative to the benchmark. The
Portfolio was overexposed to companies with yield curve risk. As the yield curve
flattened, these stocks performed poorly. That issue has been corrected and
relative performance of the Finance Sector has stabilized.
    The Portfolio held several stocks that performed well. Both Allied Group and
First Brands were acquired and the stocks performed well. Tropical Sportswear
produces high quality casual and dress men's apparel and provides major apparel
retailers with comprehensive brand management programs. The company made a great
acquisition of Savane International Corp. (formerly Farah Inc.) for $98.5
million. Tropical Sportswear has been able to leverage this acquisition very
successfully, and has landed some significant new accounts. The stock was up 259
percent* in 1998. The stock continues to be a core holding in the Portfolio but
has been trimmed back several times during the year.
    A recent addition to the Portfolio is Robert Mondavi Corp. which produces
and sells premium table wines. In 1997 and early 1998, the company did a poor
job of purchasing the grapes necessary to meet the strong demand for its
product. Its relationship with the retail trade and its earnings suffered. We
recognized early that the company had solved its problem and that its brand name
recognition continued to be strong with customers despite recent problems. The
stock has appreciated 57 percent* since it was purchased in the third quarter.
OUTLOOK
Since becoming the portfolio manager on October 1, 1998, focusing on
diversifying the Portfolio to include more stocks was a priority for me. The
Portfolio's holdings have increased from 50 stocks to 87 stocks. Since small
companies tend to have limited product or geographic diversification, we added
greater diversity, thus further limiting certain risks. We will continue to look
for undervalued companies with stable to improving fundamentals. We will also
maintain a diversified portfolio to protect against unforeseen macroeconomic
events.
    While Asia is by no means thriving, the economic problems appear to have
stabilized and the region's impact on domestic companies appears to be well
quantified. We know more about President Clinton's problems than we would
probably like, but the impeachment proceedings are closer to an end and are not
likely to be an issue to the market going forward. On the positive side, the fed
funds rate is 75 basis points lower than it was in July. This tends to be very
positive for small stocks. Small stocks are inexpensive relative to the large
stocks by virtually any measure. While it is impossible to predict when a rally
will begin for the small stocks, it is likely that a rally could be very
substantial because of the relative undervaluation of small stocks.

            Portfolio seeks

            current income
            consistent with
            protection of
            principal. The
            Portfolio pursues
its objective by investing
primarily in debt securities
issued by issuers located
anywhere in the world. Prior
to May 1, 1998, this
Portfolio was known as the
International Bond Portfolio.
While Advantus Capital
Management, Inc. acts as the
investment adviser for the
Portfolio, Julius Baer
Investment Management Inc.
provides investment advice to
the Global Bond Portfolio
under a subadvisory
agreement.
PERFORMANCE
The Global Bond Portfolio posted a total return of 16.18 percent* for the year
ended December 31, 1998. This compares to the Salomon Brothers World Government
Bond Index** return of 15.38 percent and the Salomon Brothers Non-U.S. World
Government Bond Index+ of 17.79 percent for the same period.
PERFORMANCE ANALYSIS
Global Commentary: The effects of the Asian crisis dominated the beginning of
the year. This led to a global slowdown in growth that continued through the
entire year. Rate cuts were the order of the day, as all of the world's major
economies cut interest rates to spur growth.
    Bond yields fell on the back of rate cuts, producing some of the best bond
market returns in recent history. In addition, inflation remained subdued as
global commodity prices declined across the board. In all, the year produced
ideal conditions for bond investors.
    European bond markets were the clear winners during the year, as all markets
in Europe produced double-digit returns in local currency terms. The UK led the
way at 19.55 percent for the year. The Portfolio's overweight position in
European markets was a primary driver of performance for 1998.
    The most volatile market was Japan, as the yen strengthened dramatically
during the fourth quarter. A local currency return of 0.50 percent translated
into 15.85 percent in U.S. dollar terms for 1998. Even so, Japan placed 13th out
of 18 markets in the index for the year.
    Long duration was a positive contributor to performance for 1998 as the fall
in yields was most dramatic at the long end of the curve worldwide. At the peak
early in the fourth quarter, the Portfolio was over 7 years in duration, versus
an index of 5.5 years.
U.S. Commentary: Nineteen ninety-eight was a challenging year for fixed income
investors, and especially for corporate bond and mortgage investors. At the
beginning of the year, yields in the U.S. Treasury market were attractive and
there was a high degree of comfort in the corporate and mortgage sector. As
global events began to unfold, investor sentiment swung heavily toward the
safety of the U.S. Treasury market. Interest rates plunged lower as liquidity in
corporate bonds and mortgage-backed securities disappeared. In the latter part
of the year, the Federal Reserve cut key short-term interest rates aggressively,
stocks rebounded to pre-crash highs, fears of a global meltdown subsided and
investors began a slow return to the corporate bond market.
    After the dust settled, the yield on the 30-year U.S. Treasury Bond
decreased 83 basis points to 5.09 percent. In the fourth quarter, 4.69 percent,
the lowest yield ever recorded on a 30-year U.S. Treasury Bond was reached.
Yields on intermediate maturity notes moved anywhere from 110 to 116 basis
points lower over the course of the year.
    The Portfolio's emphasis on corporate bonds and mortgage-backed securities
was in the higher quality, more liquid issues, which insulated it from pain felt
by many investors in these sectors. Entering 1999, corporate bond and
mortgage-backed spreads are at the most attractive levels since the 1990
recession.
OUTLOOK
Global Outlook: The outlook for global bond markets looks positive, as
disinflationary pressures remain strong. Weakness in commodity prices, with oil
having fallen 25 percent since late September, will support lower growth in
Europe and Latin America. If U.S. growth shows expected signs of slowing over
the coming months, bond markets will benefit from the potential for lower
interest rates.
    The Portfolio will continue to overweight the European markets based on this
slow growth scenario. A market we are watching closely is Japan, where yield
spreads have moved dramatically in favor of Japanese bonds. However, the
currency remains suspect following a large rally in the fourth quarter of 1998.

    Currency preference remains unchanged, with the euro as the favorite,
followed by the U.S. dollar and the yen. Pound sterling will come under pressure
as the prospect for rate cuts continues. Here we will maintain hedges out of
sterling into the euro to protect value in the Portfolio.
U.S. Outlook: The long-term fundamentals for the U.S. bond market are still
positive. Industrialized countries around the world are suffering from slow
economic growth and over capacity. With global demand low and the ability to
produce high, inflation will likely remain benign. Commodity prices are falling
and will likely stay depressed until worldwide economic activity begins to
strengthen. Despite the global downturn, the U.S has been an island of
prosperity in the global marketplace. Strong domestic growth with low inflation
and an accommodative Federal Reserve has kept both stocks and bonds performing
well. We anticipate that economic growth will likely slow as global pressures
finally reach the U.S. When this happens, interest rates will likely move
moderately lower and the Federal Reserve would ease rates modestly to engineer
another soft landing.

INDEX 400 MID-CAP PORTFOLIO
PERFORMANCE UPDATE
KEVIN ZWART
PORTFOLIO MANAGER
  [PHOTO]   The Index 400
            Mid-Cap Portfolio
            seeks to provide
investment results generally
corresponding to the
aggregate price and dividend
performance of publicly
traded common stocks that
comprise the Standard &
Poor's 400 MidCap Index (S&P
400).+ It is designed to
provide an economical and
convenient means of
maintaining a diversified
portfolio in this equity
security area as part of an
over-all investment strategy.
PERFORMANCE
The Index 400 Mid-Cap Portfolio posted a total return of 16.68 percent* for the
year ended December 31, 1998. This compares to the S&P 400 MidCap Index,** which
earned 19.09 percent for the same period.
PERFORMANCE ANALYSIS
Despite a 4 percent gain on the last day of the year, 1998 was a difficult year
for mid-cap stocks. While the S&P 400 MidCap Index** was up over 19 percent for
the year, technology was responsible for 13.4 percent of the return. Of that
13.4 percent, 7.1 percent was attributed to America Online (AOL), the largest
weight in the index. Consumer cyclicals were also very positive, contributing
2.7 percent to the index for the year.
    Massive inflow of investors' dollars continued to propel the large-cap
stocks, which demonstrated investors' preferences for positions in larger
companies. Mid-cap stocks remained a distant second in 1998, as evidenced by the
S&P 400 MidCap Index's** underperformance of the larger S&P 500 Index++ by the
largest margin since the inception of the mid-cap index.
OUTLOOK
AOL's increase this year took it to nearly 6 percent of the S&P 400 Index.**
Because of AOL's tremendous growth, it was moved to the S&P 500 Index++ at the
end of 1998. This will return "control" of the index to the smaller stocks. As
money continues to move into equity markets, the question to answer in 1999 is
when will investors move to smaller stocks as the place to find the best value?
We believe the value currently exists, so time will tell.

MACRO-CAP VALUE PORTFOLIO
PERFORMANCE UPDATE
MICHAEL J. KELLY
J.P. MORGAN INVESTMENT
MANAGEMENT
  [PHOTO]   The Macro-Cap
            Value Portfolio
            seeks to provide
            high total
return. It pursues this
objective by investing in
equity securities that the
sub-adviser believes, through
the use of dividend discount
models, to be undervalued
relative to their long-term
earnings power, creating a
diversified portfolio of
equity securities which
typically will have a
price/earnings ratio and
price to book ratio that
reflects a value orientation.
While Advantus Capital
Management, Inc. acts as
investment advisor for the
Portfolio, J.P. Morgan
Investment Management Inc.
provides investment advice to
the Macro-Cap Value Portfolio
under a subadvisory
agreement.
PERFORMANCE
The Macro-Cap Value Portfolio returned 22.33 percent* for the year ended
December 31, 1998. The S&P 500 Index** returned 28.57 percent during this
period, while the S&P Value Index+ returned 14.5 percent for the same period.
PERFORMANCE ANALYSIS
U.S. stock markets staged an impressive rise during the fourth quarter, driving
results for the full year and extending the S&P 500 Index's** streak of 20
percent plus returns to an unprecedented four years. Liquidity flooded financial
markets as the Federal Reserve cut interest rates three times in the space of 6
weeks in September, October, and November. As such, early fourth quarter stock
market advances were fairly broad based. However, gains that elevated the S&P
500 Index** to a record 1241 became increasingly more narrow as analysts lowered
earning expectations and as interest rates stagnated.
    The market ended a very volatile year in a rally driven by size and growth.
The largest 50 stocks outperformed the rest of the market, gaining 40 percent
versus the 17 percent for the other 450 stocks in the index. The top market-cap
quintile (above $18B) was the only market-cap segment within the index to
outperform during the year. Moreover, relative performance deteriorated steadily
with declining market cap, with the mid- to small-tiers lagging the composite
index in excess of 20 percent. So while the S&P 500 Index** closed the year near
its all-time high, the average stock in the index finished 19 percent BELOW its
52-week high. Following another well-established trend, growth stocks beat value
stocks by a wide margin in 1998: the S&P Growth Index+ was up 42.0 percent, well
ahead of 14.5 percent gain in the S&P Value Index.+
    The persistence of these patterns has led to a very narrow market--a
challenging environment for active managers, particularly those relying on
valuation-driven stock selection techniques. Against this backdrop, and relative
to most value managers, the Portfolio delivered very solid results.
    Stock selection in the technology sector proved favorable in 1998. Within
the S&P 500 Index,** technology was one of only four sectors to outperform for
the year. Prospects for growth appeared better, particularly as the PC industry
worked its way through an inventory correction. Evidence that Y2K would be a net
boost to tech spending, at least for the first half of 1999, also emboldened
investors. Meanwhile, internet stocks scaled new heights amid frenzied trading,
and offered a new rational for multiple expansion among some of the larger, more
established technology companies including EMC Corp, Sun Microsystems, Compaq
Computer, and IBM--all overweight positions in the Portfolio.
    Holdings in the consumer stable sector also boosted performance. Anheuser
Busch shares rallied on news of volume and pricing gains; and Philip Morris
stock rose with the announcement of a tobacco settlement.
    Energy stocks were among the weaker constituents of the index as well as the
Portfolio. Late-breaking potential catalysts, including Exxon's $75B acquisition
of Mobil as well as the attack on Iraq, failed to reinvigorate interest in the
sector as oil prices remained depressed. Portfolio holdings skewed towards
refining (Tosco and Valero Energy) and oil service stocks (Input/Output)
detracted from performance as shares of large, integrated oil companies fared
better in this environment.
OUTLOOK
For 1999, we expect moderation with respect to earnings, economic growth, and
share price appreciation. Positive seasonal trends and monetary conditions
should support the market as we enter the new year. However, any one of a host
of macro uncertainties has the potential to deflect stocks from extending their
recent gains: the impeachment of the president, the impact of the Euro, the year

MICRO-CAP GROWTH PORTFOLIO

            The Micro-Cap
            Growth Portfolio
            seeks long-term
            capital
            appreciation. It
            pursues this
            objective by
            investing
            primarily in
            equity securities
            of smaller
            companies which
            the sub-adviser
believes are in an early
stage or transitional point
in their development and have
demonstrated or have the
potential for above average
revenue growth. It will
invest primarily in common
stocks and stock equivalents
of micro-cap companies. While
Advantus Capital Management,
Inc. acts as investment
advisor for the Portfolio,
Wall Street Associates
provides investment advice to
the Micro-Cap Growth
Portfolio under a subadvisory
agreement.
PERFORMANCE
The Micro-Cap Growth Portfolio returned 13.44 percent* for the year ended
December 31, 1998. The Portfolio's benchmark, the Russell 2000 Growth Index,**
returned 1.24 percent for the same period.
PERFORMANCE ANALYSIS
Small-caps faced a difficult market environment through the first nine months of
1998, as investors showed a preference for liquidity. The Portfolio was down
12.9 percent* in the first nine months of the year. All of the Portfolio's gains
came in the fourth quarter when small-caps rallied, so our detailed comments
primarily address the fourth quarter. The Portfolio gained 29.97 percent* in the
fourth quarter versus the Russell 2000 Growth Index** fourth quarter return of
23.65 percent. For the calendar year 1998, the Portfolio significantly
outperformed its benchmark.
    Stock performance correlated directly with capitalization tiers in 1998.
Concerns about the health of the global economy (particularly Asia) sent
investors scurrying for the perceived stability of the larger, more liquid
securities.
    The Portfolio is concentrated in the Technology (31 percent), Consumer
Cyclical (23 percent) and Health Care (9 percent) sectors of the market. Sector
allocation proved beneficial as all of these sectors outperformed the benchmark
in the fourth quarter and in calendar year 1998. Stock selection in both the
Consumer Cyclical and Technology sectors added substantially to Portfolio
performance in 1998, particularly in the fourth quarter. The Portfolio's
Technology stocks as a group gained 61 percent,* while the Consumer Cyclical
stocks gained 33 percent* during this period. Investments in the Consumer
Staples and Communication Services sectors also produced strong returns, though
represented a smaller portion of portfolio assets.
OUTLOOK
Our outlook for small-cap stocks is quite optimistic, and we believe that
positive market forces are in place for an extension of the recent small-cap
rally. Relative valuations remain near historic lows and absolute valuations are
attractive. Cash flows into aggressive growth mutual funds have increased and
many funds still have excess cash sitting on the sidelines. The healthy cash
levels combined with a slow IPO market should, we believe, provide plenty of
support for small-cap stocks, as investors seek to capitalize on investments
with rapidly growing earnings.
    As we have mentioned in past reports, the catalyst for an extended period of
small-cap leadership will likely result from strong relative earnings growth.
Large-cap earnings are expected to be flat, at best, while small-caps are still
expected to post strong double-digit growth in earnings. Despite the favorable
earnings outlook, small-caps are still trading at a 20 percent discount to
larger issues, as a result of the liquidity premium given to larger issues
during most of 1998. The combination of historically low valuations and a
superior earnings outlook should likely fuel investors' desires to own small-cap
companies, thus likely continuing the small-cap rally well in to 1999.

REAL ESTATE SECURITIES PORTFOLIO
PERFORMANCE UPDATE
JOE BETLEJ, CFA
PORFOLIO MANAGER
 
  [PHOTO]
            The Real Estate
            Securities
            Portfolio seeks
            above-average
income and long-term growth
of capital. The Portfolio
intends to pursue its
objective by investing
primarily in equity
securities of companies in
the real estate industry. The
Portfolio seeks to provide a
yield in excess of the yield
of the Standard & Poor's
Corporation 500 Composite
Stock Price Index (S&P 500
Index).+
PERFORMANCE
The Real Estate Securities Portfolio was added to the Advantus Series Fund on
May 1, 1998. The Portfolio's return for the period from May 1 (date of
inception) to December 31, 1998 was -14.90 percent.* This compares to the
Wilshire Associates Real Estate Securities Index (WARESI)** return of -14.32 for
the same period.
PERFORMANCE ANALYSIS
Shifting perspectives in the real estate market highlighted the year for Real
Estate Securities. Fears of weakening fundamentals for real estate markets
(rents and occupancies) caused by a rapid increase in new construction starts
and a slowing economy, as well as negative news surrounding regulatory
legislation on a small number of Real Estate Investment Trusts (REITs) caused
the market to perceive more risk within the sector. Many holders of real estate
securities moved to the sidelines, putting further pressure on equity real
estate securities. The market had three messages for companies: 1). we won't let
you impair the operating fundamentals by overbuilding; 2). you must generate
higher yields to compensate for the inherent risk of this sector; and 3). you
must be more selective when employing precious capital in the market because the
equity window won't always be open. REITs began dropping out of the acquisition
and development game, capitalization rates began to rise for purchases of real
estate, and multiples assigned to the sector decreased. Compounding these issues
was the collapse of the Commercial Mortgage Backed Securities (CMBS) market and
year end tax-loss selling.
    Our opinion, however, is that these forces placed the real estate securities
in an overcorrected position when the values of these stocks plummeted during
this year. Most companies are trading at less than their underlying asset value,
dividend yields spread over intermediate-term Treasuries are at the wide end of
their trading range, and multiples for real estate securities have fallen, while
multiples for the broader market have expanded. Property level fundamentals
still remain solid in most markets, new construction has slowed, and the economy
remains in a slow growth mode, which leaves this group as a classical value
play--the market is overly discounting the future benefits of these real estate
companies. Real estate is now being priced as rationally as it had been for a
long time.
    The strongest performing sectors were Apartments, Shopping Center, Regional
Mall, and Net Lease. These sectors typically show strength in weakening economic
conditions or have long term leases that give these companies a lot of strength
through market downturns. The best performing companies within the sector focus
more on property level cashflow and less on growth of the portfolio. During the
third quarter, we added Homebuilders to the Portfolio and have achieved very
strong returns with this group after the market had oversold them. The weakest
performing sector was hotels. Overbuilding particularly hit the operating side
causing occupancies to slip for this property type. The growth in Revenue Per
Available Room (REVPAR) slowed during the year, forcing the market multiple for
this group to contract quite substantially. Additionally, the hotel sector's
exposure to paired-share REITs, which were the subject of the regulatory reform
mentioned above, kept a dark cloud over these companies for a good portion of
the year.
    As volatility built up for real estate equity securities during the year, we
took a more conservative position within the Portfolio. We became more in line
with the property type weights within the index. Our average exposure to an
individual company became smaller as we added a few more names to the Portfolio
to better diversify the Portfolio. Consistent with our investment process, as we
began to see the real estate markets approaching their peak, we began to focus
more on dividends (and their quality) within the Portfolio. Relative performance
improved as we proceeded through the year, and we feel that we are in good
position for 1999.
OUTLOOK
Our outlook for 1999 is positive for real estate stocks, consistent with a "soft
landing" economic environment as engineered by the Federal Reserve. This
scenario suggests modest, consistent growth and relatively stable interest
rates. We see modest growth for the group in 1999 with minimal downside risk.
The capital markets discipline has substantially slowed down new development,
lowering the risk of overbuilding. Given these factors, property level
cashflows, balance sheets and dividend coverage appear healthy and should likely
remain so throughout the year for many of the companies we own. REIT earnings
estimates have been stripped of any incremental acquisitions or developments
that cannot be supported by the current balance sheet. We see this trimming as
setting the stage for some upside earnings announcements, and perhaps calling a
bottom of the current market cycle. Company management should have learned some
tough lessons during 1998 and will need to establish better credibility by
employing capital more judiciously and proving the sector as it truly is--a
consistent, modest growth business with a strong dividend and the ability to
selectively add value along the way. We continue to recommend Real Estate
Securities Portfolio as a strong addition to a well-diversified investment
portfolio.

    On the chart above you can see how the Real Estate Securities
Portfolio's total return compared to the Wilshire Associates Real
Estate Securities Index and the Consumer Price Index. The three lines
represent the total return of a hypothetical $10,000 investment made
on the inception date of the Real Estate Securities Portfolio (May 1,
1998) through December 31, 1998.
 *Historical performance is not an indication of future performance. Investment
  returns on principal values will fluctuate so that shares upon redemption may
  be worth more or less than their original cost. Performance figures of the
  Fund do not reflect charges pursuant to the terms of the variable life
  insurance policies and variable annuity contracts funded by separate accounts
  that invest in the Fund's shares. When such charges are deducted, actual
  investment performance in a variable policy or contract will be lower.
**The Wilshire Associates Real Estate Securities Index is a market
  capitalization-weighted index of equity securities whose primary business is
  equity ownership of commercial real estate (REITS).
 +The S&P 500 Index is a broad, unmanaged index of 500 common stocks which are
  representative of the U.S. stock market overall.

These financial statements and the financial highlights are the responsibility
of the Funds' management. Our responsibility is to express an opinion on these
financial statements and the 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, we
request confirmations from brokers, and where replies are not received, 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.

    timing and amount of future cash flows.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 1998
 
(1) ORGANIZATION

    The Fund accounts for the assets, liabilities and operations of each
Portfolio separately. Shares of the Fund will not be offered directly to the
public, but sold only to Minnesota Life Insurance Company's (Minnesota Life),
formerly known as The Minnesota Mutual Life Insurance Company, separate accounts
in connection with Minnesota Life variable contracts and policies.
 
    On July 16, 1997, the Board of Directors approved the addition of the Real
Estate Securities Portfolio. On April 24, 1998, Minnesota Life purchased
4,000,000 shares of capital stock, which represented the initial capital in this
Portfolio at $1.00 per share. The Portfolio became effectively registered under
the Securities Exchange Act of 1933 on May 1, 1998.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    The significant accounting policies followed by the Fund are as follows:
 
  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 in the financial statements. Actual
results could differ from those estimates.
 
                                       99

NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
  INVESTMENTS IN SECURITIES
 
    Investments in securities traded on a U.S. or foreign securities exchange
are valued at the last sales price on that exchange prior to the time when
assets are valued; securities traded in the over-the-counter market and listed
securities for which no sale was reported on that date are valued on the basis
of the last current bid price, by an independent pricing service or at a price
deemed best to reflect fair value quoted by dealers who make markets in these
securities. When market quotations are not readily available, securities are
valued at fair value as determined in good faith under procedures adopted by the
Board of Directors. Short-term securities, with the exception of Money Market,
International Stock, Macro-Cap Value and Global Bond, are valued at market. For
International Stock, Macro-Cap Value and Global Bond, short-term securities with
maturities of less than 60 days when acquired, or which subsequently are within
60 days of maturity, are valued at amortized cost which approximates market
value. Pursuant to Rule 2a-7 of the Investment Company Act of 1940 (as amended),
all securities in Money Market are valued at amortized cost, which approximates
market value, in order to maintain a constant net asset value of $1 per share.
 
    Security transactions are accounted for on the date the securities are
purchased or sold. Realized gains and losses are calculated on the
identified-cost basis. Dividend income is recognized on the ex-dividend date and
interest income, including amortization of bond premium and discount computed on
a level yield basis, is accrued daily.
 
  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 Fund does not isolate that portion of the results of
operations resulting from changes in foreign exchange rates on investments from
the fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with net realized and unrealized gains or losses from
investments.
 
    Net realized foreign exchange gains or losses arise from sales and
maturities of short-term securities, sales of foreign currencies, currency gains
or losses realized between trade and settlement dates on security transactions,
the difference between the amounts of dividends, interest and foreign
withholding taxes recorded on the Fund's books and the U.S. dollar equivalent of
the amounts actually received or paid. Net unrealized foreign exchange gains and
losses arise from changes in the value of assets and liabilities, other than
investments in securities, resulting from changes in the exchange rate.
 
    International Stock and Global Bond also may enter into forward foreign
currency exchange contracts for operational purposes and to protect against
adverse exchange rate fluctuations. Global Bond may also enter into these
contracts for purposes of increasing exposure to a foreign currency or to shift
exposure to foreign currency fluctuations from one country to another. The net
U.S. dollar value of foreign currency underlying all contractual commitments
held by International Stock or Global Bond and the resulting unrealized
appreciation or depreciation are determined using foreign currency exchange
rates from an independent pricing service. International Stock and Global Bond
are subject to the credit risk that the other party will not complete the
obligations of the contract.
 
  FEDERAL TAXES
 
    The Funds policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to shareholders. Therefore, no income tax provision is required.
Each Portfolio within the Fund is treated as a separate entity for federal
income tax purposes. The Fund's policy is to make the required minimum
distributions prior to December 31, in order to avoid Federal excise tax.

NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
    For federal income tax purposes, the following Portfolios had capital loss
carryovers at December 31, 1998, which, if not offset by subsequent capital
gains, will expire December 31, 2002 through 2007. It is unlikely the Board of
Directors will authorize a distribution of any net realized capital gains until
the available capital loss carryovers have been offset or expired:
 
<TABLE>
<S>                                                                  <C>
Mortgage Securities................................................  $ 2,197,150
Small Company......................................................   15,159,260

Micro-Cap Growth...................................................      914,937
Real Estate Securities.............................................      258,130
</TABLE>
 
    Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of temporary book-to-tax
differences. The character of distributions made during the year from net
investment or realized gains may 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 (loss) or realized gains (losses) were recorded by the Fund.
 
    On the statement of assets and liabilities, as a result of permanent
book-to-tax differences, a reclassification adjustment was made as follows:

  DISTRIBUTIONS TO SHAREHOLDERS
 
    Distributions to shareholders from net investment income for Money Market
are declared and reinvested daily in additional shares of capital stock. For
Portfolios other than Money Market, distributions from net investment income and
realized gains, if any, will generally be declared and reinvested in additional
shares on an annual basis.
 
  SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
 
    Delivery and payment for securities which have been purchased by the Fund 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
fluctuations. As of December 31, 1998, the Mortgage Securities Portfolio had
entered into outstanding, when-issued or forward commitments of $758,828,
respectively. The Portfolio has segregated assets, with the Portfolio's
custodian, to cover such when-issued and forward commitments.
