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 39.
 
    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.

LETTER FROM THE PRESIDENT
 
Dear Shareholders:
 
Investors experienced a positive financial environment with moderate economic
growth and low inflation throughout 1997. The inflation fears experienced in the
first half of the year dissipated as negative economic events in Asia unfolded
and took on global implications during the fourth quarter.
 
The "Asian Flu" severely affected several Far Eastern currencies and stock
markets, leaving a trail of bankruptcies, uncertainties, and fears in its wake.
In fact, a "flight to quality" poured assets into U.S. markets, particularly the
bond market, which is a popular destination for investors during periodic
flights to quality.
 
Broadly speaking, both equity and fixed income securities have demonstrated
notable results this reporting period. Indices, such as the S&P 500 Index,*
which increased 33.4 percent for the year; and the Lehman Brothers Government
Corporate Bond Index,** which increased 9.7 percent for the same period,
reflected the general strength of the equity and fixed income markets,
respectively, in 1997.
 
Within both the broad equity and fixed income markets, there are market segments
that perform differently. On the equity side, there was a disparity of results
between large cap and small cap stocks. For example, the Russell 1000 Growth
Index,+ used to benchmark our Growth Portfolio, earned 30.5 percent for the
year. The Russell 2000 Growth Index,+ used to benchmark our Small Company
Portfolio, earned 12.9 percent for the same period. This is not unusual. The
inherent differences in these portfolios allow you to diversify your investments
within one product.
 
You will notice that five new portfolios have been added to this Series Fund
since our last report. The portfolios are Small Company Value, Index 400
Mid-Cap, International Bond, Macro-Cap Value and Micro-Cap Growth. Commentaries
from the portfolios' managers appear in the PORTFOLIO MANAGER REVIEWS section.
 
The investment professionals at Advantus Capital Management continue to put
their money management expertise to work on your behalf. We appreciate your
continued participation in the Advantus Series Fund.
 
Sincerely,
 
             [SIGNATURE]
 
Robert E. Hunstad
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 total return for the Growth Portfolio was 33.41 percent* for the year ended
December 31, 1997. The Portfolio exceeded its benchmark, the Russell 1000 Growth
Index,** which earned 30.48 percent for the same period.
    In prior reporting periods, the S&P 500 Index+ was used as the Portfolio's
benchmark. The S&P 500, a broad market index, does not fully reflect the
Portfolio's growth investment style. The Russell 1000 Growth Index** is a widely
accepted benchmark for large capitalization portfolios, such as the Growth
Portfolio. The Portfolio's performance will be compared to the Russell 1000
Growth Index** going forward.
PERFORMANCE ANALYSIS
Driven by the lower interest rates and the continued strong earnings growth
rates, the Finance sector was the Portfolio's strongest performer, up 68
percent* for the year. Meaningfully contributing to performance were stocks such
as Norwest Corporation and Associates First Capital Corporation. Conversely, the
Materials and Service sector lagged the Portfolio, generating only a 19 percent
return.* A computer services company, First Data Corporation, reported
disappointing sales and earnings, as well as year 2000 costs that exceeded
expectations. This was the primary cause for weakness in the Materials and
Service area.
    Lower inflationary pressures had little effect on the Portfolio's
performance. Additionally, the economic situation in Asia caused only a minor
slowdown during the fourth quarter, which was offset by the strength in Europe.
Responding to the situation in Asia, investors sought out more stable growth
companies consistent with the stocks in the Portfolio. Consequently, valuations
in those companies increased during the fourth quarter.
OUTLOOK
Near term, there are several events lining up to make 1998 a difficult year to
show strong corporate earnings growth. The year 2000 issues will force companies
to spend money on people to fix technology problems rather than purchasing new
systems. The Asian situation will likely slow economic growth and lead to
increased pricing pressure as Asia's cost of production has fallen dramatically.
Finally, the strong earnings of 1997 have set a tough standard for 1998.
    We will continue to invest in what we believe to be the best companies. We
look for companies with superior management or product positions that can
continue through the current environment with sustainable above average
long-term earnings growth rates.

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, 1997 the Portfolio returned 9.42 percent.* The
Portfolio's benchmark, the Lehman Brothers Government Corporate Bond Index,**
returned 9.75 percent for the same period. Our net performance was .33 percent
less than the index benchmark.
PERFORMANCE ANALYSIS
The bond friendly interest rate environment was the primary force that produced
returns in the high single digits. When interest rates fall, bond prices rise,
adding a capital appreciation component to the Portfolio's total return.
Calendar year 1997 was a better-than-average year for bond investors as interest
rates fell across the yield curve. The yield on the two-year U.S. Treasury Note
decreased 23 basis points to yield 5.64 percent, while the yield on the 30-year
U.S. Treasury Bond declined 72 basis points to 5.92 percent.
    Subdued inflation continues to be the theme driving interest rates lower.
Our positive outlook on inflation supported our bullish bias throughout the
year. Even though the economy experienced some strong quarterly growth, there
were no signs of inflation in the system. This lack of inflationary pressures
gave us the confidence to maintain above-average duration in the Portfolio
throughout most of the year.
    Economic problems, which have been brewing in Asia for some time, came to
the forefront and have received considerable media attention in the fourth
quarter. From an interest rate and yield curve standpoint, the crisis in Asia
has had a positive impact on U.S. Treasury prices. There are two main points
here. First, the U.S. has become an importer of deflation because of the
financial problems in Southeast Asia. The goods produced in this region and
exported to the U.S. have become significantly cheaper for American consumers.
Second, the Asian crisis has removed any near-term possibility that the Federal
Reserve will raise short-term interest rates.
    From a security specific standpoint, the Asian crisis has significantly
widened credit spreads on all U.S.-pay international bonds. When spreads widen,
bond prices decline. Two of the Hong Kong-based holdings in the Portfolio,
Guangdong Enterprises and Wharf International Finance, were negatively affected
as their credit spreads widened in the fourth quarter.
    There are three main sectors in the fixed income market: U.S. Government
securities, corporate bonds, and mortgage-backed securities. During 1997, all
three sectors performed well, with corporate bonds finishing the year with a
slight lead because of their longer maturities. In the Portfolio we maintained
our over-emphasis on corporate bonds because of their incremental yield and
total return characteristics. This strategy worked very well the first nine
months of the year, but hurt performance in the fourth quarter as credit spreads
widened mainly due to concerns stemming from Southeast Asia.
    Our investment approach to the fixed income market is to evaluate all of the
available alternatives and purchase the best possible relative value.
OUTLOOK
We anticipate that 1998 will be a very interesting year for fixed income
investors, a year where having reasonable investment return expectations will be
important. Keep in mind that a successful year in the fixed income market is
where you earn the coupon and generate some price appreciation through lower
interest rates or credit improvement. In this regard, 1997 was a successful year
for investors. Starting the year from a historically low level of interest rates
leaves less room for error. Interest rates can move lower because the
fundamentals of this market are very positive. We have low inflation, moderate
economic growth, and a financial crisis in Asia that will pressure interest
rates lower. We think 1998 will be an "earn the coupon" year with the
opportunity for some moderate price appreciation as interest rates trade in a
lower range.
    Of the three fixed income sectors, U.S. Treasury notes and bonds will likely
offer excellent value in the upcoming year. With worldwide financial uncertainty
there will be a flight to quality, and the U.S. Treasury market offers a lower
risk opportunity to investors. As the U.S. budget deficits shrinks, a smaller
supply of U.S. Treasury securities will be met with higher demand. This should
be a positive for the bond market. To take advantage of this flight to quality,
the U.S. Treasury component of the Portfolio will be increased at the expense of
corporate bonds. Corporate bonds will continue to be a core holding, but to a
lesser degree. The Asian crisis will likely continue to have a negative impact
on corporate spreads, (pushing them wider) so we will cut back on out corporate
exposure in 1998.

    On the chart above you can see how the Bond Portfolio's total
return compared to the Lehman Brothers Government Corporate Bond Index
and the Consumer Price Index. The three lines represent the total
return of a hypothetical $10,000 investment made on December 31, 1987
through December 31, 1997.
 *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 Lehman Brothers Government Corporate Bond Index is an unmanaged benchmark
  composite of the Lehman Brothers Government Bond Index which includes all
  publicly issued debt of the U.S. Government and Agencies and The Lehman
  Brothers Corporate Bond Index which includes all publicly issued fixed rate,
  nonconvertible domestic corporate debt.

MONEY MARKET PORTFOLIO
PERFORMANCE UPDATE
WAYNE SCHMIDT, CFA
PORTFOLIO MANAGER
 
  [PHOTO]
            The Money Market
            Portfolio seeks
            maximum current
income to the extent
consistent with liquidity and
the preservation of capital.
It invests in short-term
money market instruments and
other debt securities that
mature within 397 days.
INVESTMENT IN THE MONEY
MARKET PORTFOLIO IS NEITHER
INSURED NOR GUARANTEED BY THE
U.S. GOVERNMENT, AND THERE
CAN BE NO ASSURANCE THAT THE
PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET
VALUE OF $1.00 PER SHARE.
PERFORMANCE
The Money Market Portfolio's total return for the year ended December 31, 1997
was 5.11 percent.* The seven-day compounded yield at December 31, 1997 was 5.16
percent.* At the end of the reporting period, the yield on the three-month U.S.
Treasury Bill was 5.34 percent.
PERFORMANCE ANALYSIS
With low inflation and moderate economic growth, short-term interest rates have
been extremely stable over the past few years. For 1997, the yield on the
three-month U.S. Treasury Bill increased 15 basis points to yield 5.34 percent.
This is still below the Fed Funds rate, which is targeted at 5.50 percent. With
the Federal Reserve keeping its monetary policy unchanged, short-term interest
rates have traded in a very narrow range. In the Money Market Portfolio, the
average days to maturity was 45 days, slightly shorter than the average money
market fund.
    The financial crisis in Asia has not directly impacted the quality of U.S.
commercial paper issuers, but it has had an impact on short-term U.S. interest
rates. The Asian crisis removed the immediate possibility for the Federal
Reserve to raise short-term interest rates and has actually increased the
likelihood that the Fed's next move would be to lower interest rates. The
uncertainty in Asia should lead to stable or falling short-term interest rates.
    Corporate commercial paper continues to be the Portfolio's major emphasis
because of its yield advantage over U.S. Treasury Bills and Agency paper. At
year-end, 92 percent of the portfolio was invested in high quality commercial
paper (i.e. first tier or A-1/P-1 commercial paper).
OUTLOOK
Short-term interest rates will be driven by Federal Reserve action and economic
activity. With the currency problems and economic uncertainties in Asia, the
Federal Reserve Board will likely be forced to either leave short-term rates
unchanged or eventually lower them in the first half of 1998. With inflation
non-existent and economic growth slowing, look for money market rates to decline
slightly as 1998 progresses.
    Our emphasis will continue to be on corporate commercial paper because it
offers greater yield potential in this market. We will also seek to extend the
average days of maturity in the Portfolio to take advantage of what we believe
to be higher short-term interest rates early in the year.

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 earned 18.99 percent* for the year ended December
31, 1997. The Portfolio's benchmark, a blend comprised of 60 percent Russell
1000 Growth Index** and 40 percent Lehman Brothers Aggregate Bond Index+ earned
11.62 percent for the same period.
    In prior reporting periods, the Merrill Lynch-Wilshire Capital Markets
Index++ was used as the Portfolio's benchmark. The Merrill Lynch-Wilshire
Capital Markets Index,++ which includes all publicly traded equity and debt
securities now assigns a disproportionate weighting to equities. A blend,
comprised of 60 percent Russell 1000 Growth Index** and 40 percent Lehman
Brothers Aggregate Bond Index+, is a more appropriate benchmark for our
conservative asset allocation approach in the Advantus Series Fund Asset
Allocation Portfolio. The Portfolio's performance will be compared to this blend
of indices (60 percent Russell 1000 Growth Index** and 40 percent Lehman
Brothers Aggregate Bond Index+) going forward.
PERFORMANCE ANALYSIS
Solid performance was demonstrated on both the stock and bond sides of the
Portfolio. Stocks in the Portfolio were bolstered with an overweighted position
in Financials, a strong performer throughout the year, and an underweighted
position in Technology, which became a falling star in the fourth quarter. We
were also underweighted in Consumer Staples, which was one of the strongest
sectors of the market.
    Our economy continues to experience moderate growth and low inflation. Lower
inflationary pressures in the U.S. economy have lead to higher price to earnings
valuations in the stock market--a continuing theme over the past few years.
Lower inflation has also lead to lower bond yields. This prompted us in November
to decrease the Portfolio's bond allocation to 35 percent from 40 percent. The
currency crisis in Asia indirectly fueled the bond market rally in the U.S. and
created an opportunity to sell bonds and add stocks to the Portfolio.
    Our target asset allocation, as of December 31, 1997, was 55 percent stocks,
35 percent bonds and 10 percent cash. We have been opportunistic to achieve this
asset allocation. By taking advantage of the bond rally and the trickle-down
effects of the Asian economic crisis, the rebalancing in November allows us to
manage the Portfolio consistently with its stated objective. The Portfolio's
objective charges us with seeking as high a level of long-term total rate of
return as is consistent with prudent investment risk for investors. We do this
by investing for capital appreciation in companies with superior long-term
growth potential. We also maintain positions in quality, fixed income securities
to generate income and provide stability for investors.
OUTLOOK
Near term, there are several events lining up to make 1998 a difficult year to
show strong corporate earnings growth. The year 2000 issues will force companies
to spend money on people to fix problems rather than purchasing new systems. The
Asian situation will likely slow economic growth and lead to increased pricing
pressure as Asia's cost of production has fallen dramatically. Finally, the
strong earnings of 1997 have set a tough standard to beat in 1998.
    A return to more "normal" performance from the stock market is likely during
the first half of 1998. Given the historically high valuations placed on stocks,
and the slowing earnings growth rate, it is not likely that stocks will gain 20
percent like they did in the first half of 1997. With slowing economic
pressures, no signs of inflation, and a Federal Reserve that cannot really
tighten until the Asian situation is resolved, bonds look to provide moderate
yet attractive returns for the first half of 1998.

MORTGAGE SECURITIES PORTFOLIO
PERFORMANCE UPDATE
KENT WEBER, CFA
PORTFOLIO MANAGER
 
  [PHOTO]
            The Mortgage
            Securities
            Portfolio seeks a
            high level of
current income consistent
with prudent investment risk.
The Mortgage Securities
Portfolio will invest
primarily in mortgage-related
securities.
PERFORMANCE
The Mortgage Securities Portfolio returned 9.14 percent* for the year ended
December 31, 1997. The Portfolio's benchmark, the Lehman Brothers
Mortgage-Backed Securities Index,** returned 9.49 percent for the same period.
PERFORMANCE ANALYSIS
Broadly speaking, this is the second straight year that the mortgage market
outperformed duration-matched Treasuries. In 1997, the performance was about 1.2
percent on average. A relatively benign interest rate environment steadily
improved credit fundamentals and helped to propel the mortgage market forward.
Never the less, with interest rates moving lower throughout the reporting
period, the mortgage market has seen its duration shorten from 3.7 years to 2.5
years, which truly makes the mortgage market a low duration asset class.
    The Portfolio's duration was held 10 to 12 percent longer than the index
throughout the reporting period. This benefited the Portfolio, as interest rates
fell by about .5 percent, thus adding some price appreciation on top of healthy
income.
    We are always watchful of prepayment risk. Prepayment concerns escalated as
interest rates moved lower. Our stance grew more conservative as we moved to
protect the Portfolio by reducing our exposure to securities with higher loan
rates--the securities most likely to be refinanced.
    Throughout the year, we added mortgages that we felt rewarded us for the
amount of risk we incurred. When interest rates began moving lower, the
following strategies were put in place:
    - Reduced exposure to mortgages with high loan rates.
    - Continued emphasis on securities that are prepayment challenged or carry
      restricted rights to prepay.
        - Overweight in vintage securities (i.e., well-seasoned mortgage
          securities of about five to 10 years), as compared to new issues.
        - Purchased AAA rated securities consisting of mortgage loans with low
          balances (below $65,000) made to first time homeowners at below market
          interest rates.
    - Development of a more broadly diversified portfolio to avoid reliance on
      any one sector of the mortgage market.
        - Increased allocation of commercial mortgage-backed securities.
        - Increased holdings in non-agency, investment-grade securities.
          (Investment-grade securities are those rated BBB and above.)
    The Asian currency situation has elicited some secondary effects in the
mortgage market. It has put downward pressure on domestic and global interest
rates and inflation, which have rekindled the topic of refinancing (and
prepayments). Fortunately, not all mortgage securities are created equally which
allows the market to treat prepayments like stock earnings with respect to
meeting--or not meeting--expectations on how the price moves.
OUTLOOK
We see the Portfolio's position as well situated. It is broadly diversified,
utilizing numerous sectors of the mortgage market. We are also ready to handle
an inherent increase in volatility that occurs due to the low interest rate
levels. We like high quality securities from both a credit and cash flow
perspective. Some predictability is comforting.
    There may be opportunity for some price appreciation on top of coupon
income, which could potentially lead to mid to high single digits for 1998. We
anticipate that the market will experience slow growth and mild inflation, which
sets the stage for a fixed-income friendly year. Although we are in the late
innings of the recovery that started in 1993, we see no recession looming.

INDEX 500 PORTFOLIO

  [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, 1997, the Index 500 Portfolio returned 32.36
percent.* The S&P 500** returned 33.34 percent for the same period.
PERFORMANCE ANALYSIS
The Index 500 Portfolio consists of publicly traded common stocks representing
leading companies in virtually all segments of the American economy. The
Portfolio is designed to reflect the results that correspond to the investment
performance of the stock market, in general. We seek to accomplish this by using
a computer model that positions the Portfolio to optimally track the conduct of
the S&P 500.**
    The Utilities and Energy sectors lagged the market during the first three
quarters of 1997. They rebounded in the fourth quarter and achieved significant
gains. Technology's high weighting in the index detracted significantly from the
performance.
OUTLOOK
The Asian currency problems are likely to be reflected in corporate earnings
during the first half of 1998. If corporate earnings lag in 1998, the Asian
debacle will be blamed for shortfalls that occur. Low interest rates will likely
continue to provide a very important floor for stocks. We anticipate moderate
growth, as well.

CAPITAL APPRECIATION PORTFOLIO
PERFORMANCE UPDATE
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 third consecutive year, the equity market exceeded most investors'
expectations. Total return for the Capital Appreciation Portfolio was 28.26
percent* for the year ended December 31, 1997. The Portfolio's benchmark, the
Russell 1000 Growth Index** gained 30.48 percent for the year, while the S&P 500
Index+ advanced 33.34 percent.
PERFORMANCE ANALYSIS
Although absolute returns were highly favorable in 1997 and considerably
exceeded the long-term annual equity returns of 10.8 percent, again only a small
minority of money managers outperformed their appropriate benchmarks. According
to Indata, a company that monitors investment performance, the S&P 500+ beat 87
percent of all equity mutual funds in 1997 and 90 percent of all large cap
growth funds for the last five years.
    The year ended December 31, 1997, marks the fourth year in a row the largest
stocks performed best. Only 35 stocks in the Russell 1000 Growth Index** have a
market capitalization greater than $34 billion. These mega cap stocks returned
in excess of 35 percent and outperformed all other market capitalization
sectors. Over their four years of outperformance, they have experienced
annualized returns of 28 percent, nearly 10 percent higher than the broad market
results.
    The investment philosophy of the Portfolio is based on the belief that
owning companies with above-average future earnings growth potential will
produce superior investment return potential over the long-term. We also are
sensitive to valuation--what you pay in price/earnings ratio for that future
growth rate. The philosophy is implemented by mixing several medium
capitalization stocks with large cap growth issues. This means that we generally
will be underweighted in the very largest companies and financial stocks because
these types of companies usually cannot achieve earnings growth in excess of 13
percent annually.
    The Portfolio was able to overcome the underperformance of medium
capitalization companies through strong stock selection in a variety of
different sectors. Over the last two years the Portfolio has maintained an
overweighted position in technology and specialty retail companies. Many of
these companies outperformed the market in 1997. An example includes Dollar
General Corporation (+75 percent), Home Depot, Inc. (+75 percent), Kohl's Inc.
(+73 percent), Computer Associates International (+64 percent) and Microsoft
Corporation (+59 percent).
    During the fourth quarter, the companies in the Portfolio reported an
average increase in earnings of 32 percent compared with a year ago. This gives
us confidence that the companies will be able to achieve our projected growth
rate in earnings per share for 1998 of 25 percent. While the Portfolio sells at
a moderate P/E premium to S&P 500,+ it has delivered several times the expected
growth of the index. In our opinion, this is an attractive combination of
relative valuation and strong future earnings growth.
OUTLOOK
The question now is whether the largest companies will continue to outperform or
whether the broad market will exhibit better relative performance in 1998. For
two major reasons, earnings and valuation, it is our belief that the broad
market is poised to take the lead. We expect gross domestic product (GDP) growth
in the U.S. to slip from 3.5 percent in 1997 to around 2 percent in 1998. In
this environment, earnings growth is much more dependent on unit gains. We
believe the problems from the Asian turmoil will probably be somewhat worse than
expected. However, the difficulties are not significant enough to derail the
U.S. economic outlook. Corporate profits could be moderately affected, so we
expect flat to slightly up S&P 500+ earnings. With inflation declining to 1.5
percent or lower, interest rates may recede further providing support for the
current S&P 500+ price/earnings ratio of 19x. The biggest risk is that earnings
are disappointing and the stock market declines even in a falling interest rate
environment.
    We remain committed to our investment discipline of searching out those
opportunities in companies with the demonstrated ability to grow their
businesses at above-average rates regardless of the near-term macro economic
environment. This commitment has allowed the Portfolio to outperform all major
market indices, including its benchmark index, the Russell 1000 Growth Index,**
for the last three quarters. On balance, we continue to believe the large and
competitive U.S. economy provides many opportunities to find good growth ideas.

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
The International Stock Portfolio increased 11.94 percent* for the year ended
December 31, 1997, versus the Morgan Stanley Capital EAFE Index** return of 2.03
percent for the same period. On average, the Portfolio has returned 17.09
percent per year for the five-year period ending December 31, 1997, compared to
the EAFE** average annual return of 11.70 percent over the same period.
PERFORMANCE ANALYSIS
International equity markets had mixed results during 1997. The European and
Latin American markets were strong, while the Asian markets suffered a material
downfall. The economic crisis in Southeast Asia that occurred late in the year
dominated economic news and sent a ripple effect throughout international equity
markets, as investors feared the effect of the crisis on global economic growth.
The Portfolio therefore benefited from large positions in strong-performing
European equities and a modest exposure to Asia.
    The Portfolio's largest regional exposure is in Europe, with approximately
72.8 percent of the Portfolio's total assets invested in European equities. With
continued growth in corporate earnings, subdued inflation and success in
corporate restructuring, we continue to find value in this area. This high
exposure fared well, as some of the Portfolio's strongest contributors were
European names, including Banco Bilboa, BG PLC and Deutsche Bank, which posted
84.1 percent,* 69.3 percent* and 54.2 percent* returns for the year,
respectively.
    The turbulence in Asian economies dominated global economic news and sent a
shock throughout international markets in the latter portion of 1997. Increased
worries from currency weaknesses and bad debts in Asian corporations resulted in
material contractions in stock prices throughout the region, and the majority of
Asian markets posted double-digit declines. Due to a relatively low exposure of
only 8.5 percent of total assets in the Asian markets, the Portfolio was
somewhat protected from the economic turmoil.
    Latin American equity markets also performed well over 1997. This region
currently represents approximately 9.1 percent of the Portfolio's total assets.
A notable performer from the region and one of the Portfolio's largest holdings
included Telecomunicacoes Brasileiras SA, the Brazilian national telephone
company, which increased 56 percent* over the year. The Latin American markets
experienced a downturn in the latter portion of the year, however, in response
to the economic crisis in Asia. We feel that this correction has increased
investment opportunities and we continue to search for bargains in the area.
OUTLOOK
Going forward, we remain optimistic towards the international equity markets.
When compared to U.S. equities, which remain at historically high valuations,
international equities appear better able to provide value. While the Asia
crisis has warranted extra caution for investing in this area, we view the
recent downturn in the Asian markets as an opportunity to find bargains.
    We will continue to use our disciplined approach to purchase undervalued
securities, while maintaining a balanced portfolio to continue to achieve strong
long-term performance for the Portfolio.

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 7.75 percent* for the year ended December
31, 1997. Its benchmark, the Russell 2000 Growth Index,+ returned 12.94 percent
for the same period.
    In prior reporting periods, the Wilshire MidCap Index++ was used as the
Portfolio's benchmark. The Russell 2000 Growth Index+ better reflects the size
and style bias of a small company growth portfolio than does the Wilshire MidCap
Index,++ which no longer corresponds to the market capitalization of the Small
Company Portfolio. The Portfolio's performance will be compared to the Russell
2000 Growth Index+ going forward.
PERFORMANCE ANALYSIS
The Portfolio's performance over the past year lagged its benchmark index, and
hence did not meet our expectations. Before addressing some topics specific to
the Portfolio's performance, let's briefly discuss the small company growth
"climate" as compared with other equity securities.
    For the third consecutive year, domestic stocks posted strong results.
Investors' thirst for liquidity and perceived quality of larger stocks drove the
valuations of larger stocks to all-time highs. Meanwhile, small-and mid-sized
stocks lost ground, and smaller growth stocks were left in the dust.
    The indices show the Russell 1000 Index+ of larger stocks returned 32.86
percent for the year, while the Russell 2000 Growth Index+ (e.g. our benchmark
index) returned 12.94 percent. These indices are very different because they
reflect distinctly different segments of the equity market. Numerous earnings
announcements, which came in below expectations, led to a significant division
between large and small stocks and also within small stocks (between those
considered growth stocks and value-oriented stocks).
    Investors who put their money into small stocks selected companies where
they were comfortable with current earnings and low valuations, but forfeited
the "potential" growth expected in faster growth stocks with higher betas. (Beta
is a method of measuring the volatility of a stock in comparison with the market
as a whole. Beta values above 1.0 indicate volatility.)
    For the year, the top performing sectors within the Russell 2000 Growth
Index+ of smaller companies were Consumer Staples and Utilities. Both areas had
absolute returns of more than 40 percent. However, due to their small weights in
the index, they made limited contributions to overall results. Technology was
the worst absolute performing sector, gaining only .2 percent, while Health Care
returned 8.9 percent. Technology and Health Care stocks comprised more than 35
percent of the index weight, thus holding back results significantly. The top
contributor to performance in the index was the Consumer Discretionary sector.
    Strong performers in the Portfolio for the period included a number of
companies in the capital goods area. These economically sensitive stocks
continue to have strong operating performance and outlooks. Included in this
group is American Disposal Services, Inc., a solid waste company that has
demonstrated outstanding growth through internal operations and has acted as a
consolidator in its industry, opening new territories for the company. Another
strong performer, Kaydon Corporation, designs and manufactures custom-engineered
specialty products, including anti-friction bearings, bearing systems, custom
rings, and seals. These products are used in a wide variety of medical,
aerospace and industrial applications. Continued growth in their end markets and
the specialty nature of these products have led to very strong operating
performance and growth for the company.
    As mentioned earlier, technology stocks were the worst performers in the
market, as well as in our portfolio. Earnings disappointments and concerns about
the impact of the Asian economic crisis have negatively impacted many of these
stocks. Stocks like Danka Business Systems (worldwide distributor of
photocopiers and other business machines) and CKS Group Incorporated (marketing
communications services) had significant earnings disappointments due to poorly
executed corporate strategies. Neither company is currently held in the
Portfolio.
    Consumer cyclical stocks, which include retail and restaurants, always seem
to be a large part of our Portfolio due to the number of high growth
opportunities in this sector. The year brought mixed results in this area with
retailers, such as Borders Group Incorporated (book superstores) and Pacific
Sunwear of California (young men's and women's apparel) doing well, while
apparel manufacturers, such as Nautica Enterprises, Inc. were hurt by the
perception of slowing demand and inventory concerns. Restaurant companies, such
as Boston Chicken Incorporated and Lone Star Steakhouse & Saloon, Inc.,
performed poorly and were sold during the year.
    Much of the underperformance, outside of Technology, can be pinned to a
handful of investments in companies that reported well below estimated earnings.
Prior to these announced shortfalls, the companies
 
                                       20
<PAGE>
showed strong operating results with no signs of trouble. Each company was
seemingly healthy and growing well when investors were told of an unexpected
earnings shortfall. The shortfalls stemmed from a variety of reasons, and in a
few cases, the company's management was less than forthright prior to the
problem.
    Small company stocks are volatile. When investing in small, fast growing
companies, there will be occasional blowups when a company's management is
unable to execute at the fast growth pace. We have made minor, yet appropriate,
changes in how we monitor our companies' results. We want to minimize the
frequency of negative surprises. To do so, we believe careful analysis of a
company's fundamentals holds the key to long-term results. Our overriding focus
remains on long-term results that benefit investors.
OUTLOOK
We remain cautiously optimistic going into 1998. The volatility seen in the
markets, though at times unsettling, is no greater than what we saw in the late
1980s and early 1990s. Given the relatively benign economic backdrop with
moderate growth, little inflation, and declining interest rates, we expect to
continue to find companies that are growing fast and are likely to be rewarded
with higher stock valuations. Notwithstanding the market's fluctuations or the
potential for further problems out of Asia, we believe rigorous analysis of
company fundamentals is the key to long-term investment success and continues to
be our focus.
    Our style emphasizes individual stock selection. As such, we do not spend
much time trying to guess which sectors are most attractive. The over- and
underweights of sectors in the Portfolio are a function of the individual
opportunities we find. Certainly, with the sell-off in the energy and technology
areas, several stocks have potentially been painted with the same negative
brush, but are in fact doing exceedingly well. We are considering individual
issues within these areas that fit our investment criteria--specifically
companies with strong fundamentals and reasonable valuations.

PERFORMANCE ANALYSIS
Our investment activities remain focused on tracking the performance of the
respective indices. To reach these goals, we continue to use a variety of
Government Agency bonds. By selectively using Government securities in concert
with Treasury securities, the Portfolios benefit from enhanced diversification,
as well as from the receipt of additional income (over Treasury securities).
    As time passes, the duration of each portfolio continues to roll forward
toward its respective maturity. The effective duration of each portfolio now is
as follows:

OUTLOOK
We see the Portfolios' position as well situated. We are also ready to handle an
inherent increase in volatility that occurs due to the low interest rate levels.
We anticipate that the market will experience slow growth and mild inflation,
which sets the stage for a fixed-income friendly year.

VALUE STOCK PORTFOLIO
PERFORMANCE UPDATE
MATTHEW FINN, 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
The Value Stock Portfolio returned 21.19 percent* for the year ended December
31, 1997. In comparison, its benchmark, the S&P Barra Value Index,** earned
29.98 percent for the same period.
PERFORMANCE ANALYSIS
The economic situation in Asia that unfolded in the fourth quarter affected the
Portfolio's performance.
    As the U.S. lowered its export levels to Asia, our gross domestic product
(GDP) was reduced as well. These results created a rotation away from some
economically sensitive sectors, as investors anticipated slower domestic
activity. This has hurt the Basic Materials, Capital Goods, Energy, and
Technology sectors while boosting Consumer Staples and Utilities.
    The Portfolio gained relative performance in the last quarter of the year
from holdings in Financial Services and Basic Materials. The Portfolio's
Financial holdings rose more than the market, and the Portfolio's holdings in
Basic Materials fell less. The largest negative impacts on performance were
Capital Goods, Consumer Staples, and Technology.
    A specific holding that impacted the Portfolio's year-end return was Lam
Research Corporation (LRCX), a technology stock that we held for much of the
reporting period. LRCX manufactures its products in the U.S. and exports them to
Asian markets. Consequently, the Far Eastern currency debacle had a negative
effect on Lam Research's earnings. In addition, LRCX stock declined in
anticipation of downward earnings revisions.
    Our focus has been--and will remain--on companies that offer both low
relative valuations and expected improvements in operating performance.
OUTLOOK
During the first six months of 1998, we expect that the market and the Portfolio
will continue to be impacted by sentiment swings regarding economic activity and
Asia-related economic issues. No segments of the market stand out as offering
excellent value and rapid improvement in operating performance. The holdings in
the Portfolio represent investments in companies that are attractive, rather
than sector bets.
    Within the Portfolio, we will continue to rotate out of relatively
overvalued segments, such as regional Bells and banks, as we find attractive
opportunities. We will also be watchful of buying opportunities as companies
report earnings disappointments related to their Asian operations.

small companies, defined in
terms of market
capitalization and which
appear to have market values
which are low relative to
their underlying value or
future earnings and growth
potential.
PERFORMANCE
The Small Company Value Portfolio returned 2.29 percent* for the period from
October 1 (date of inception) to December 31, 1997. The Russell 2000 Value
Index** returned 1.68 percent for the same period.
PERFORMANCE ANALYSIS
During the fourth quarter, the economic situation in Asia played a role in the
Portfolio's performance. DuPont Photomasks Incorporated (semiconductor supplies)
had substantial business in Asia, and the stock has been sold off in
anticipation of lower earnings.
    Stock selection in the Energy, Finance, Technology and Basic Materials
sectors contributed most significantly to positive relative performance versus
the Russell 2000 Value Index.** However, Consumer Cyclical and Capital Goods
stock selection hurt relative performance. The Portfolio was also negatively
impacted by Brown Group, Inc.'s (shoe manufacturing and retailing) announcement
of an earnings shortfall in their Brazilian operations.
OUTLOOK
During the first six months of 1998, we expect that the market and the Portfolio
will continue to be impacted by sentiment swings regarding economic activity and
Asia-related economic issues. No segments of the market stand out as offering
value and rapid improvement in operating performance. The holdings in the
Portfolio represent investments in companies that are attractive, rather than
sector bets.
    No substantial changes are planned within the Portfolio. However, we will be
watchful of buying opportunities as companies report earnings disappointments
related to their Asian operations.

INTERNATIONAL BOND PORTFOLIO
PERFORMANCE UPDATE

JULIUS BAER INVESTMENT
MANAGEMENT
 
  [PHOTO]
            The International
            Bond Portfolio
            seeks to maximize
current income consistent
with protection of principal.
The Portfolio pursues its
objective by investing
primarily in a managed
portfolio of non-U.S. dollar
denominated debt securities
issued by foreign
governments, companies and
supranational entities. While
Advantus Capital Management,
Inc. acts as investment
advisor for the Portfolio,
Julius Baer Investment
Management Inc. provides
investment advice to the
International Bond Portfolio
under a subadvisory
agreement.
PERFORMANCE
The International Bond Portfolio returned .08 percent* for the period from
October 1 (date of inception) to December 31, 1997. This compares to the Salomon
Brothers Index** return of -1.38 percent for the same period.
PERFORMANCE ANALYSIS
All of the major bond markets exhibited positive local currency returns during
the fourth quarter of 1997. Italy, the U.S. and the U.K. were the best
performers. Italy advanced on the back of interest rate cuts and increasing
certainty that it will be a founding member of European Economic and Monetary
Union, while U.K. gilts and U.S. Treasuries rallied on expectations of slower
growth and, especially in the case of the U.S., safe haven flows out of Asia.
Nonetheless, market returns available to dollar-based investors, as in the third
quarter, were less favorable. Weakness of the Yen and Deutschmark more than
offset the local returns in Japan and core Europe. The best U.S. dollar-based
total returns were achieved in the U.K. and Italy.
OUTLOOK
Economic developments in Asia, and the fear of deflation, will remain the key
focus in the upcoming months. The big question for investors is how much the
region's troubles will impact growth in Japan, the U.S. and Europe. In Japan,
pessimism has become entrenched; the government's fiscal package in December
1997 failed to assure both investors and consumers. The prospect of no growth
next year, though not our central forecast, remains a real threat. In Europe,
the recovery continues, but at an unimpressive rate. Only in the U.S., where
activity remains robust, are inflationary pressures close to the surface.
    We believe that bond markets continue to offer value, and a neutral-to-long
exposure is warranted. However, bond market valuations are a shade expensive,
thereby limiting the room for further yield falls. In terms of the currency, the
weakness of the Japanese economy is likely to further undermine the Yen. The
dollar has been driven higher against the Yen and the Deutschmark by relatively
strong U.S. and weak Japanese and German growth. That picture is unlikely to
change radically in the near term, so the dollar should be well supported in the
coming quarter. However, as the year progresses, the Deutschmark is expected to
reassert itself, supported by relative growth and interest rates, as well as
favorable valuations.

INDEX 400 MID-CAP PORTFOLIO
PERFORMANCE UPDATE
TERI BRANDT
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 returned .06 percent* for the period from
October 1 (date of inception) to December 31, 1997. The S&P 400 Index** returned
 .83 percent for the same period.
PERFORMANCE ANALYSIS
The Index 400 consists of 400 domestic stocks chosen for market size (median
market capitalization of about $610 million), liquidity and industry group
representation. It is a market-weighted index (stock price times shares
outstanding), with each stock affecting the index in proportion to its market
value. The index is comprised of approximately 66 percent industrials, 18
percent utilities, 15 percent financials and 1 percent transportation.
    The Portfolio is designed to match closely the investment performance of the
S&P 400** segment, as described above. We seek to accomplish this by using a
computer model that positions the Portfolio to optimally track the conduct of
the S&P 400.**
    Of all the midcap market segments, Financials posted the largest gain by
far, with 73.0 percent for the year. Consumer Cyclical, which posted a 31.6
percent return for the year, ranked second, and Communication Services ranked
third with a 38.6 percent gain. Sectors receiving the laggard awards were Health
Care and Basic Material, returning 5.5 percent and 17.36, respectively.
OUTLOOK
The Asian currency problems are likely to be reflected in corporate earnings
during the first half of 1998. If corporate earnings lag in 1998, the Asian
debacle will be blamed for shortfalls that occur. Low interest rates will
continue to provide a very important floor for stocks. We anticipate moderate
growth, as well.

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 -2.13 percent* for the period from
October 15 (date of inception) to December 31, 1997. This compares to the S&P
500 Index** return of 2.87 percent for the period from October 1, 1997 to
December 31, 1997. Because the Portfolio's inception date was mid-month October,
we are not able to provide benchmark performance for the same period because the
information is not available. We are providing total return information for
benchmark performance from the previous month end to the end of the reporting
period.
PERFORMANCE ANALYSIS
The U.S. equity market continued to exhibit strong returns during 1997. The S&P
500** rose 2.87 percent during the fourth quarter, contributing to its 33.34
percent return for the year. However, strong returns masked the sudden and
violent increase in market volatility, particularly during the fourth quarter.
The Asian financial crisis stunned the U.S. equity market in October, with
aftershocks reverberating throughout the remainder of the period and into 1998.
    Overall U.S. equity market returns continue to be dominated by the largest
capitalization stocks deemed the "Nifty Fifty," a trend which has been present
for several years. Emphasis on the largest, most liquid stocks was particularly
apparent during the fourth quarter as investors sought less turmoil in the midst
of emerging markets turmoil. In fact, during the fourth quarter, the S&P's
largest fifty stocks delivered nearly twice the return of the entire S&P 500
Index.**
    This narrow market environment made it very difficult for the majority of
active managers to keep pace with the S&P 500.** As we continue to view many of
the "Nifty Fifty" stocks as extremely overvalued, we have not held them in the
Portfolio. This caused us to trail the S&P 500** over the period. However,
because the Portfolio is well diversified and fully invested in stocks, our
returns outpaced those of similar active equity managers.
    Stock selection in the Portfolio's Energy, Multi-industry, and Services
sectors were particularly strong. Energy stocks such as Tosco Corporation and
Input/Output, Inc. contributed positively to overall return. The Multi-industry
sector made a significant contribution with Westpoint Stevens, Inc. and Waste
Management, Inc. In the Services sectors, Telecommunications Inc. and U.S. West
Media Group had positive impacts.
OUTLOOK
During 1998, we expect that GDP (gross domestic product) will likely grow at a
more trend-like rate of 2.7 percent and that inflation may rise to 2.25 percent
as wage pressures begin to be felt during this latter stage of a prolonged
economic expansion. We expect that corporate profits will likely remain strong,
though lower than their double-digit levels of the past few years. We will aim
to consistently add value in the Portfolio by using fundamental research to
identify individual stocks that are underpriced relative to their longer-term
earnings prospects.

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 -13.20 percent* for the period from
October 1 (date of inception) to December 31, 1997. This compares to the Russell
2000 Growth Index** return of -8.19 percent for the same period. The
differential in return is almost fully described by the average-weighted market
cap of the Portfolio. At approximately $160 million, it is much smaller than the
average-weighted market cap of the Russell 2000 Growth Index,** which is $830
million.
PERFORMANCE ANALYSIS
The market for growth investors in 1997 reflected three distinct investment
climates. The liquidity driven market that began in the summer of 1996 and
continued through the end of April 1997 marked the first climate. The climate
was exacerbated by concerns of an overheated economy and Chairman Greenspan's
comments about investors' "irrational exuberance." The second climate was driven
by a surprise budget agreement and its provisions for a capital gains tax cut.
This, coupled with evidence that inflation was of little concern, drove oversold
growth stocks from the end of April through early October. The final investment
climate was driven by the precipitous drop in the Thai currency, which sent
shock waves throughout Asia. The year was characterized by significant liquidity
premiums for large stocks and swift, deep declines as one moved down the
capitalization spectrum.
    The Portfolio was funded in September, 1997. This virtually coincided with
the precipitous drop in the markets resulting from the Asian crisis and was
exacerbated by the flight to quality (or the move to the larger capitalization
issues).
OUTLOOK
Going forward, we are increasingly optimistic about the outlook for smaller
capitalization growth stocks. The following factors are all positives for the
Portfolio:
    - The expected slowdown in S&P earnings makes growth stocks much more
compelling.
    - Valuations are attractive on both an absolute and relative basis.
    - Interest rates are at 20-year lows and inflation is benign.
    - Investor sentiment is negative (bullish). Not one IPO was priced above the
      filing range for December 1997.
    - The persistent demand for imbalance for equities continues.

    shares of common stock.

    On April 24, 1997 shareholders of the Fund approved a name change to
Advantus Series Fund, Inc. (effective May 1, 1997). Prior to May 1, 1997 the
Fund was known as MIMLIC Series Fund, Inc. 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 The Minnesota Mutual
Life Insurance Company's (Minnesota Mutual) separate accounts in connection with
Minnesota Mutual variable contracts and policies.
 
    On July 17, 1996, the Board of Directors approved the addition of the Small
Company Value Portfolio and on January 14, 1997, the Board of Directors approved
the addition of the International Bond, Index 400 Mid-Cap, Micro-Cap Value,
Macro-Cap Value and Micro-Cap Growth Portfolios. These six additional portfolios
became effectively registered under the Securities Exchange Act of 1933 on May
1, 1997; however they were not available for sale to the public until a later
date. The Small Company Value, International Bond, Index 400 Mid-Cap, Macro-Cap
Value and Micro-Cap Growth Portfolios became available in October 1997. As of
December 31, 1997, shares of the Micro-Cap Value Portfolio are not available for
sale.
 
    Minnesota Mutual purchased shares of capital stock, which represented the
initial capital in these portfolios, at $1.00 per share as follows:

NOTES TO FINANCIAL STATEMENTS--CONTINUED
 
(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 of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of increases and decreases in net assets
resulting from operations during the period. Actual results could differ from
those estimates.
 
  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 International Bond, are valued at
market. For International Stock, Macro-Cap Value and International 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 International Bond also may enter into forward
foreign currency exchange contracts for operational purposes and to protect
against adverse exchange rate fluctuations. The net U.S. dollar value of foreign
currency underlying all contractual commitments held by International Stock or
International Bond and the resulting unrealized appreciation or depreciation are
determined using foreign currency exchange rates from an independent pricing
service. International Stock and International Bond are subject to the credit
risk that the other party will not complete the obligations of the contract.
 
  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, 1997, the Bond, Asset Allocation and Mortgage
Securities Portfolios had entered into outstanding, when-issued or forward
commitments of $920,073, $1,697,705 and $3,587,131, respectively. The Portfolios
have segregated assets, with the Portfolios' respective custodians, to cover
such when-issued and forward commitment transactions.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
  FEDERAL TAXES
 
    The Fund's 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.
 
    For federal income tax purposes, the following Portfolios had capital loss
carryovers at December 31, 1997, which, if not offset by subsequent capital
gains, will expire December 31, 2002 through 2006 for Mortgage Securities and
December 31, 2005 through 2006 for Small Company and Small Company Value. 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.................................................  $2,885,335
Small Company.......................................................   3,214,146
Small Company Value.................................................      53,657
</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 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.
 
(3) INVESTMENT SECURITY TRANSACTIONS
    For the year ended December 31, 1997, the cost of purchases and proceeds
from sales of investment securities aggregated $651,385,296 and $647,340,039,
respectively, for Money Market. For the other portfolios, the cost of purchases
and proceeds from sales of investment securities, other than temporary
investments in short-term securities, for the period ended December 31, 1997
were as follows:

    On September 30, 1996, the shareholders of Growth approved a sub-advisory
agreement between MIMLIC Management and Voyageur Fund Managers, Inc. (Voyageur).
Under the sub-advisory agreement, effective October 1, 1996, MIMLIC Management
paid Voyageur a fee equal to .25 percent of net assets of Growth. Effective May
1, 1997 the sub-advisory agreement between MIMLIC Management and Voyageur was
terminated.
 
    The Fund bears certain other operating expenses including outside directors'
fees, federal registration fees, printing and shareholder report expenses, legal
fees, audit fees, custodian fees, organizational costs and other miscellaneous
expenses. Each portfolio will pay all expenses directly related to its
individual operations. Operating expenses not attributable to a specific
portfolio will be allocated based upon the proportionate net asset size of each
portfolio. Minnesota Mutual directly incurs and pays these operating expenses
relating to the Fund and the Fund in turn reimburses Minnesota Mutual. Minnesota
Mutual has voluntarily agreed to absorb all fees and expenses for each portfolio
that exceed various percentages of average daily net assets. During the year
ended December 31, 1997, Minnesota Mutual voluntarily agreed to absorb $34,208,
$36,833, $37,425, $38,967, $11,517, $14,670, $22,940 and $11,102 in expenses
that were otherwise payable by Maturing Government Bond 1998, Maturing
Government Bond 2002, Maturing Government Bond 2006, Maturing Government 2010,
Small Company Value, Index 400 Mid-Cap, Macro-Cap Value and Micro-Cap Growth,
respectively.
 
    Each Portfolio pays an administrative services fee to Minnesota Mutual for
accounting, legal and other administrative services which Minnesota Mutual
provides. Prior to May 1, 1997, the administrative services fee for each
portfolio was $2,400 per month. Effective May 1, 1997, the administrative
service fee for each portfolio is $2,500 per month.

(7) ILLIQUID SECURITIES
    Each portfolio of the Fund currently limits investments in illiquid
securities to 15% of net assets at the time of purchase, except for Money Market
which limits the investment in illiquid securities to 10% of net assets. At
December 31, 1997, investments in securities of Bond, Money Market, Asset
Allocation, Mortgage Securities, Value Stock and International Stock include
issues that are illiquid. The aggregate values of illiquid securities held by
Bond, Money Market, Asset Allocation, Mortgage Securities, Value Stock and
International Stock at December 31, 1997 were $15,763,274, $3,212,588,
$22,511,186, $9,549,762, $7,984,496 and $8,627,529, respectively, which
represent 11.3%, 6.0%, 4.4%, 9.6%, 3.8% and 3.0% of net assets, respectively.
Securities are valued by procedures described in note 2. Pursuant to guidelines
adopted by the Fund's board of directors, certain unregistered securities are
determined to be liquid and are not included within the percent limitations
specified above.
 
(8) YEAR 2000
    In 1995, Minnesota Mutual began addressing computer systems requirements and
applications to be Year 2000 ready. Based on a current study, Minnesota Mutual
plans to spend approximately $14 million through 1999 to modify its computer
information systems, enabling proper processing of transactions relating to the
year 2000 and beyond. The Fund will not be charged for these expenses.

(a)  Total return figures are based on a share outstanding throughout the period
     and assumes reinvestment of distributions at net asset value. Total return
     figures 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.
(b)  Beginning in 1996, the Portfolio is required to disclose an average
     brokerage commission rate. The rate is calculated by dividing the total
     brokerage commissions paid on applicable purchases and sales of stocks for
     the period by the total number of related shares purchased and sold.
(c)  Effective May 1, 1997, the Portfolio entered into a new investment advisory
     agreement with Advantus Capital Management, Inc. Prior to May 1, 1997 the
     Portfolio had an investment advisory agreement with MIMLIC Asset Management
     Company.

(a)  The inception of the Portfolio was May 3, 1993, when its shares became
     effectively registered under the Securities Act of 1933.
(b)  Total return figures are based on a share outstanding throughout the period
     and assumes reinvestment of distributions at net asset value. Total return
     figures 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. For periods less than one year,
     total return presented has not been annualized.
(c)  Minnesota Mutual voluntarily absorbed $9,532 and $30,330 in expenses for
     the year ended December 31, 1994 and the period from May 3, 1993 to
     December 31, 1993. Had the Portfolio paid all fees and expenses, the ratio
     of expenses to average daily net assets would have been .92% and 1.58%,
     respectively and the ratio of net investment income (loss) to average daily
     net assets would have been .21% and (.70%), respectively.
(d)  Adjusted to an annual basis.
(e)  Beginning in 1996, the Portfolio is required to disclose an average
     brokerage commission rate. The rate is calculated by dividing the total
     brokerage commissions paid on applicable purchases and sales of stocks for
     the period by the total number of related shares purchased and sold.
(f)  Effective May 1, 1997, the Portfolio entered into a new investment advisory
     agreement with Advantus Capital Management, Inc. Prior to May 1, 1997 the
     Portfolio had an investment advisory agreement with MIMLIC Asset Management
     Company.
