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 40.
 
    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.

LETTER FROM THE PRESIDENT
 
                                                  [PHOTO OF WILLIAM N. WESTHOFF]
Dear Shareholder:
 
In the first six months of 1998, the U.S. economy continued to expand at a
robust pace, despite signs of slowing. The economic expansion is broad based
which illustrates the overall strength of our economy. Asian demand for U.S.
goods has been shrinking, as evidenced by the significant trade drag on U.S.
output growth during the second quarter. The fallout from the Asian financial
situation is underway, and the effects will intensify throughout the year. The
result will be declining U.S. growth through the remainder of 1998. Keep in mind
that the United States has the broadest, strongest economy in the world. Even
though we anticipate our economic growth will slow, our country's economy will
remain healthy.
 
From a global perspective, the Asian financial crisis continues to unfold and
has had a dampening effect on interest rates and corporate earnings. Ironically
this situation could have an overall positive impact on the U.S. stock market.
Equities continue to benefit from the relatively low level of interest rates,
with expansion capital available to companies at a low cost. Also, money
continues to flow into the U.S. markets at record levels. A "flight to quality"
has brought foreign investors to the shelter of the U.S stock market and to
Treasury securities. Meanwhile, western European equities have shown good
results, and we expect that Europe will continue to provide favorable long-term
results. Investing in developing countries is still fraught with risk for both
debt and equity securities investors.
 
In the bond market, the structural backdrop points to a falling trend in U.S.
bond yields, but potential domestic inflationary pressures have temporarily
stalled the decline. Recent events throughout Asia, and most recently in Japan,
have served to bring forward the expected bond rally. The spread of financial
market distress to much of the developing world has reduced the risk that the
Federal Reserve Board will have to tighten monetary policy further in this
cycle.
 
In the stock market, cash flows into the stock market have dominated valuations
and pricing. The stock market has benefited from both the flight to quality
(from abroad) and from the huge and continuing cash flows from the funding of
retirement assets. Equity valuations are on the high side of almost any
historical comparisons, with large cap (and consistent) growth stocks leading
the valuation parade. A strong and steady bond market has propped up stock
prices. This continues even within an environment of slightly slower growth
expectations.
 
The broad array of portfolios within the Advantus Series Fund affords investors
many choices. Investors, with the guidance of their financial representative,
should review their portfolio to ensure that it is sufficiently diversified with
a variety of fixed income and equity products, including some international
exposure.
 
Thank you for investing with Advantus.
 
Sincerely,
 
           [WILLIAM N. WESTHOFF SIGNATURE]

Growth Portfolio
 
PERFORMANCE UPDATE
THOMAS GUNDERSON, CFA
PORTFOLIO MANAGER
[PHOTO OF TOM GUNDERSON]
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 19.43 percent* for the six
month period ended June 30, 1998. In comparison, the Russell 1000 Growth Index**
returned 20.38 percent for the same period.
 
PERFORMANCE ANALYSIS
 
Superior stock selection allowed the Portfolio to produce performance that
exceeded the majority of its peers over the past six months. Our emphasis on the
analysis of individual company fundamentals allowed the Portfolio to produce the
solid results. Stocks that were the biggest contributors to performance over
this period were Lucent Technologies Incorporated (telecommunications
equipment), Microsoft Corporation (software), Cisco Systems, Inc. (data
networking) and Wal-Mart Stores (retailing). Like the overall market, our best
performing stocks were also the largest companies as these stocks continued to
produce strong earnings growth and continue to be favored by the market. In
addition to these very large companies were several companies that have helped
the Portfolio. Galileo International, Inc. (airline reservation systems) gained
63 percent during the first quarter, as this company continued to post
consistent earnings growth. Tyco International, Ltd. (diversified capital goods)
gained 40 percent, as they continued to make wise acquisitions that can allow
the company to continue its excellent earnings growth. Stocks from the Consumer
Cyclical sector such as Carnival Corporation (cruise products) and Tandy
Corporation (consumer electronics) also contributed to performance. Carnival
continues to post revenue and earnings that indicate solid fundamentals, while
Tandy has sold off its non-core divisions and has some strategies in place at
its Radio Shack stores that allowed the stock to be a strong performer.
 
    Like all time periods, not all of the stocks in the Portfolio met our
expectations. ADC Communications reported weak fundamentals and was trimmed from
the Portfolio. Also, Cendant Corporation was sold after its reported "accounting
irregularities." These stocks along with Intel, Philip Morris Companies, Inc.
and Sybron International Corporation were the laggards in the Portfolio over the
past six months. We continue to analyze the fundamentals of these companies,
along with all the companies in the Portfolio, to ensure that they have the
sustainable growth characteristics that we are looking for to provide attractive
long-term capital gains for the Portfolio. If we are not convinced these
companies "have what it takes" to produce superior long-term earnings growth,
they will be trimmed from the Portfolio and replaced with better prospects.
 
    Looking at the Portfolio from a more "macro" perspective, the best sectors
were the Capital Goods sector (led by Tyco) and Consumer Cyclicals (led by
Carnival), followed closely by Technology and Health Care. This is in contrast
to the Russell 1000 Growth Index** where the strongest performance came from the
Technology sector, followed by the Health Care sector.
 
    The trend where the very largest growth companies continue to significantly
outperform the rest of the market continues. Measured by the 20 largest stocks
in the 600 plus stock Russell 1000 Growth Index,** these very large stocks
gained about 32 percent for the six month period while the remaining stocks in
the index gained about 9 percent. In other words, excluding these "top 20"
companies the Russell 1000 Growth Index** would have shown a 9 percent return
versus the 20.4 percent return for the entire Russell 1000 Growth Index.** This
is what one would call a "narrow market" as the majority of the returns are
coming from a short list of companies. Our Portfolio has had meaningful
representation, yet less than the index, in these stocks which allowed the
Portfolio to participate in the strong market performance during the first six
months of 1998.
 
OUTLOOK
 
Earnings growth is likely to be more difficult to produce if the Asian economic
problems have a slowing effect on the U.S. companies. As a result, the market
will likely place a higher valuation premium on the companies that can sustain a
continuation of superior earnings growth. Using our ONE-STOCK-AT-A-TIME
fundamental analytical approach we will continue to search the market for these
potential companies that look to produce stronger earnings growth.

Bond Portfolio
 
PERFORMANCE UPDATE
WAYNE SCHMIDT, CFA
PORTFOLIO MANAGER
[PHOTO OF WAYNE SCHMIDT]
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 six month period ended June 30, 1998, the Bond Portfolio returned 3.23
percent.* The Portfolio's benchmark, the Lehman Brothers Government Corporate
Bond Index,** returned 4.17 percent for the same period.
 
PERFORMANCE ANALYSIS
 
Interest rates continued their moderate decline in the first half of 1998 as
concern for strong U.S. economic growth was offset by low inflation, slow global
economic growth and political instability in many countries. The yield curve
flattened as rates on 30-year bonds declined 30 basis points to yield 5.63
percent while 2-year notes declined only 17 basis points to yield 5.48 percent.
 
    The U.S. bond market is comprised of three main sectors: U.S. Government
securities, corporate bonds, and mortgage-backed securities. During the past
seven years, corporate bonds have been the best performing sector for many of
the same reasons that the equity market has performed so well. Strong corporate
earnings and cash flows, positive mergers and acquisitions financed with equity
swaps, an eight-year business expansion and improving credit fundamentals.
During this run, corporate bonds have endured three setbacks. The first was in
the first quarter of 1994 when the Federal Reserve began raising interest rates
and investors feared an economic slowdown. The second was in the fourth quarter
of 1997 when the first round of the Asian crisis resulted in wider corporate
spreads. The most recent was in the second quarter of 1998 as the second round
of Asian problems coupled with foreign currency devaluations, political
uncertainty, and a huge supply of corporate bonds pushed spreads to their widest
levels since 1992.
 
    Long-term U.S. Treasury Bonds were the best performing sector in the first
half of 1998. They benefited from the flattening of yield curve and a flight to
quality by bond investors. As bond investors became worried about global
uncertainties, their appetite for U.S. Treasury securities increased. This
demand, along with a smaller supply of U.S. Treasury securities drove U.S.
Treasury bond prices higher.
 
    The performance of the Portfolio was negatively affected by the overweight
position to the corporate bond sector. Our view is that the setback to corporate
bonds is a temporary phenomenon, not a new trend. Merger and acquisition
activity continues to be positive for bondholders, earnings and cashflows remain
strong, and demand for yield product continue to increase. Corporate bonds still
have the best long-term track record and we will continue to find and hold the
best relative values in this sector.
 
OUTLOOK
 
Interest rates will likely continue to be range bound and eventually grind lower
as the year progresses. Economic growth will likely begin to slow and inflation
will remain low as the Asian crisis, Japan and the strong dollar begin to
negatively affect our economy. The Federal Reserve will need to see signs of
slower growth and higher unemployment before they are willing to reduce
short-term interest rates. This could happen by early 1999, paving the way for
lower bond yields. This is positive for fixed income investors. In the
Portfolio, we will continue to own enough duration and take advantage of the
opportunities offered in the U.S. bond market.

Money Market Portfolio
 
PERFORMANCE UPDATE
WAYNE SCHMIDT, CFA
PORTFOLIO MANAGER
[PHOTO OF WAYNE SCHMIDT]
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 six month period ended June
30, 1998 was 2.48 percent.* The three-month U.S. Treasury Bill returned 2.68
percent for the same period.
 
PERFORMANCE ANALYSIS
 
The yield on the three-month U.S. Treasury declined 25 basis points to yield
5.09 percent. Short-term interest rates continue to be remarkably stable as the
Federal Reserve continues to target the Fed Funds rate at 5.50 percent. The
Federal Reserve's last change to monetary policy was twelve meetings ago in
March 1997, when they raised the Federal Funds target by 25 basis points to 5.50
percent. Many investors began to anticipate that the Federal Reserve would soon
raise short-term interest rates to combat the U.S. economic strength and the
growing concern over wage inflation. The Federal Reserve confirmed everyone's
fears when the minutes from their March meeting were released to find that they
had adopted a bias to raising interest rates. Looking entirely at the domestic
factors, one could conclude that the Federal Reserve would have the latitude to
raise interest rates. However, given the global economic situation, a Federal
Reserve move would worsen an already difficult situation.
 
    Our emphasis in the Portfolio continues to be on the highest quality
commercial paper. This sector accounts for 87.2 percent of the portfolio
holdings. Large U.S. corporations continue to report excellent earnings and
their credit quality trends remain positive. We like this sector because of its
yield advantage, low risk and excellent liquidity. The average days to maturity
of the Portfolio was extended from 53 days to 66 days to reflect our outlook for
lower short-term interest rates ahead. The average money market fund portfolio
is running 58 days to maturity.
 
OUTLOOK
 
In the Portfolio, we will continue to purchase commercial paper from the highest
rated U.S. corporations. These investment vehicles provide money market
investors with safety, liquidity and an attractive yield. With short-term
interest rates hovering around five percent and inflation running at 1.5
percent, a 3.5 percent real return is attractive by historical standards. The
future direction of short-term interest rates will be determined by Federal
Reserve policy, inflation, economic growth rates, and currency exchange rates.
The Federal Reserve will carefully monitor these activities and refrain from
raising interest rates. Looking ahead to 1999, the discussion of Fed policy may
shift to lowering interest rates as the U.S. economy begins to show signs of
slower growth with very moderate inflation. We will also continue to keep our
average days to maturity at or above the industry average.

Asset Allocation Portfolio
 
PERFORMANCE UPDATE
THOMAS GUNDERSON, CFA
PORTFOLIO MANAGER
[PHOTO OF TOM GUNDERSON]
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 12.61 percent* for
the six month period ended June 30, 1998. The Portfolio's benchmark, a blend
comprised of 60 percent Russell 1000 Growth Index** and 40 percent Lehman
Brothers Aggregate Bond Index+ returned 13.96 percent for the same period.
 
PERFORMANCE ANALYSIS
 
The financial markets were driven by the stock market during the first half of
1998. Robust corporate profits along with stable to lower interest rates, low
inflation, and continued healthy money flows into the market allowed the stock
market, as measured by the S&P 500,++ to gain 17.6 percent for the six month
period ended June 30, 1998. The fixed income markets (bonds, mortgages) and cash
(money market) posted low single digit returns for the period. Once again, the
place to be was in stocks.
 
    Early in January stocks were purchased to increase the Portfolio's holdings
from 55 percent of the Portfolio to 60 percent as stocks had lagged the rally in
the bond market. Later in April, following another short-term stock market
correction, we again purchased 5 percent more in stocks and concurrently sold 5
percent from bonds. The current asset allocation is 69 percent stocks, 28
percent bonds, 3 percent cash.
 
    Superior stock selection allowed the Portfolio to produce performance that
exceeded the majority of its peers over the past six months. Our emphasis on the
analysis of individual company fundamentals allowed the Portfolio to produce the
solid results. Stocks that were the biggest contributors to performance over
this period were Lucent Technologies Incorporated (telecommunications
equipment), Microsoft Corporation (software), Cisco Systems, Inc. (data
networking) and Wal-Mart Stores (retailing). Like the overall market, our best
performing stocks were also the largest companies, as these stocks continue to
produce strong earnings growth and continue to be favored by the market. In
addition to these very large companies, were several companies that have helped
the Portfolio. Galileo International, Inc. (airline reservation systems) gained
63 percent during the first half of 1998, as this company continued to post
consistent earnings growth. Tyco International, Ltd. (diversified capital goods)
gained 40 percent as they continued to make wise acquisitions that may position
that company to continue its excellent earnings growth. Stocks from the Consumer
Cyclical sector such as Carnival Corporation (cruise products) and Tandy
Corporation (consumer electronics) also contributed to performance. Carnival
continues to post revenue and earnings that indicate solid fundamentals, while
Tandy has sold off its non-core divisions and has some strategies in place at
its Radio Shack stores that allowed the stock to be a strong performer.
 
    Over the past six months we purchased some REIT's (Real Estate Investment
Trusts) into the Portfolio. Valuation levels on the REIT's became more
attractive as they lagged the stock market rally. Additionally, they produce an
attractive current yield.
 
    The bonds in the Portfolio continue to give an attractive current yield and
provide diversification and stability to the Portfolio. Over the past six months
interest rates continued their longer-term trend lower, instigating our lowering
of the bond weighting in the account to 30 percent from 35 percent at the start
of the year. As interest rates move lower, bonds are generally less attractive
compared to stocks within our approach to managing the portfolio.
 
OUTLOOK
 
Over the next six months the market will be focused on corporate profits and the
impact Asian economic problems will have on the U.S. companies. Another focus of
the markets will be to more closely monitor wages, and the possible increases
that they may have on inflation. To date these issues have not been a problem,
but that does not mean there will not be concerns that the market needs to deal
with in the future.
 
    As always, we will continue to monitor the financial markets and seek to
position the Portfolio to meaningfully participate during market advances, while
protecting your capital during periods of market decline.

Mortgage Securities Portfolio
 
PERFORMANCE UPDATE
KENT WEBER, CFA
PORTFOLIO MANAGER
[PHOTO OF KENT WEBER]
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 performance for the Mortgage Securities Portfolio for the six month period
ended June 30, 1998 was 3.67 percent.* The Portfolio's benchmark index, the
Lehman Brothers Mortgage-Backed Securities Index** returned 3.38 for the same
period.
 
PERFORMANCE ANALYSIS
 
Broadly speaking, the mortgage market put in another period of solid performance
by slightly outperforming duration-matched Treasuries, on average, over the past
six months. A relatively benign interest rate environment steadily improved
credit and demand 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 a steady increase in prepayment activity.
As a result of these conditions, the duration of the mortgage market shortened
from 3.2 years to 2.4 years, and thus maintains the mortgage market as one of
the highest yielding asset classes available to fixed income investors today.
 
    The Portfolio's duration was held approximately 7 percent longer than the
index throughout the reporting period. This benefited the Portfolio as interest
rates fell by about .35 percent, thus adding some price appreciation on top of
healthy income. Income-oriented investors can be assured that this Portfolio is
broadly diversified among the various sectors of the mortgage market
(residential, commercial, pass-throughs, collateralized mortgage obligations,
etc.) and holds securities that are among the highest credit and cash flow
quality. High quality is evidenced by the Portfolio's overall rating of AA, as
well as the fact that the Portfolio is structured to carry less prepayment risk
than the index.
 
    We are always sensitive to prepayment concerns because in this asset class,
prepayment risk is a fact of life. By adhering to our consistent and disciplined
approach, we found it necessary to make only certain adjustments to the
Portfolio during this reporting period. The adjustments that we made were small
and incremental over the reporting period to reflect changing fundamentals,
which validated that the Portfolio was well positioned going into this
lower-rate environment. As interest rates drifted, the following strategies were
put in place:
    - Reduced exposure to mortgages with high loan rates.
    - Continued development of broad diversification, which reduces our exposure
      to any one sector.
    - Continued emphasis on securities that are prepayment challenged or carry
      restricted rights to prepay.
    - Purchased securities consisting of mortgage loans with low balances (below
      $65,000) made to first time homeowners at below market interest rates.
    - Increased asset allocation of commercial mortgage-backed securities.
    - Swapped credit risk for prepayment risk.
    - Increased holdings in non-agency investment grade securities. (Investment
      grade securities are those securities rated BBB and above).
 
    The Asian economic situation has elicited some secondary effects in the
mortgage market. A "flight to quality" has investors seeking shelter in Treasury
securities at the expense of both higher yielding mortgage-backed securities and
corporate bonds. This "flight" has put downward pressure on domestic and global
interest rates, which has led to an increase in the general level of refinancing
activity. Only a handful of securities have borne the brunt of this prepayment
wave (For example, short maturity securities such as adjustable rate, balloon,
and high coupon mortgages, in which we remain underweighted.).
 
OUTLOOK
 
We believe the Portfolio is well situated. It is broadly diversified, utilizing
numerous sectors of the mortgage market to add value. We continue to favor high
quality securities from both a credit and cash flow perspective. We think some
predictability is comforting.
 
    There may be opportunity for some price appreciation on top of coupon
income, which could lead to mid to high single digit returns for 1998. We
anticipate that the overall market will likely experience consistent growth and
some mild inflation, which sets the stage for a fixed-income friendly year.
 
    The combination of strong growth, paired with volatile global conditions
placed the Federal Reserve Board on hold for the near term. Meanwhile, inflation
is extremely docile and shows little evidence of rearing its head. It is
inflation, not growth, which drives interest rates. Therefore, with inflation
averaging around 2 percent and growth oscillating between 1 and 4 percent, we
look for rates to ultimately stabilize and perhaps even move moderately lower by
the end of the year. The current environment remains bond-friendly.

Index 500 Portfolio
 
PERFORMANCE UPDATE
TERI BRANDT
PORTFOLIO MANAGER
[PHOTO OF TERRI BRANDT]
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
 
The Index 500 Portfolio generated a total return of 17.25 percent* for the six
month period ended June 30, 1998. This compares to the S&P 500 Index,** which
earned 17.68 percent for the same period.
 
PERFORMANCE ANALYSIS
 
A handful of sectors played a key role in the Portfolio's performance during the
reporting period. Technology turned in solid performance for the first half of
1998, outperforming the market. Owing mainly to the increases in the computer
software and computer services industry and the computer networking industry.
Health Care, Financial and Consumer Cyclicals also posted gains to the
Portfolio.
 
    Transportation and Utilities sectors had the smallest contribution to the
Portfolio in this reporting period. The worst performer was the Energy sector,
hurt by a decline in utilities and a plunge in oil prices to nine-year lows. So
far this year, the largest and smallest stocks have shown the strongest
performance. The middle of the market has lagged in comparison.
 
OUTLOOK
 
The positive story for large-cap stocks will likely continue. The larger the
better, in that the largest companies in the S&P 500** have shown the best
performance for year-to-date returns, while the middle and bottom companies
continue to turn in lower gains during the same period.
 
    Hopes for small but steady gains to come in corporate earnings without
serious inflation should help to push stocks further. The Technology sector was
the largest mover to the Portfolio's return year-to-date. The big question now
is how the technology stocks will do amid continued worries about weak Asian
demand.

Capital Appreciation Portfolio
 
PERFORMANCE UPDATE
CLARK WINSLOW, CFA
WINSLOW CAPITAL
MANAGEMENT
[PHOTO OF CLARK WINSLOW]
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
 
Total return for the Capital Appreciation Portfolio was 21.06 percent* for the
six month period ended June 30, 1998. This compares favorably with the return of
the Portfolio's benchmark. The Russell 1000 Growth Index** increased 20.38
percent, while the S&P 500 Index+ appreciated 17.68 percent for the same period.
 
PERFORMANCE ANALYSIS
 
The trend of the largest market capitalization companies outperforming the broad
market continued to affect the market for the first six months of 1998. Only 37
stocks in the Russell 1000 Growth Index** have a market capitalization greater
than $46 billion and comprise 57 percent of the Index's** value. These mega cap
stocks returned in excess of 26 percent through June 30, 1998 and outperformed
all other market capitalization sectors by more than 10 percent.
 
    The investment philosophy implemented by Winslow Capital Management in the
Portfolio is based on the belief that investing in companies with strong future
earnings growth potential will provide higher potential 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 that have performed strongly in the
recent past.
 
    The Portfolio's overweighted positions in technology, healthcare and
specialty retailing companies were additive to results in the first six months
of 1998. The best performing holdings in the Technology sector for the six
months were Cisco Systems, Inc. and Microsoft Corporation with price moves of 65
percent.* The Portfolio's average technology stock appreciated 31 percent* for
the first two quarters. The Portfolio's healthcare investments on average moved
up 40 percent,* with Warner-Lambert Company's 68 percent* move leading the way.
In addition, the specialty retailers owned in the Portfolio advanced 35
percent,* with Tommy Hilfiger Corporation up over 75 percent.* During the same
time period the Finance and Energy sectors detracted from the overall return. In
the Financial Service sector, the average holding appreciated 7 percent.* We are
slightly overweighted in the Energy sector and our companies declined 14
percent,* but it is a small part of the Portfolio and the long-term outlook is
favorable.
 
OUTLOOK
 
Winslow Capital follows a fundamental "bottom up" investment process that leads
us to companies with above-average future earnings growth potential.
Above-average growth potential is a necessity, but valuation of the stock is
also important. These investment philosophy guidelines have led us to
overweighted positions in the Consumer, Technology and Health Care sectors
relative to our benchmark. We look for individual stocks in these sectors to
report strong earnings and do not foresee the need to position the Portfolio
differently for the upcoming quarters. In the most recent quarter, the average
reported earnings gain for the companies in the Portfolio was 30 percent.*
 
    We continue to expect GDP growth of 2 percent for the remainder of 1998.
Growth in Europe and the U.S., which represents 85 percent of S&P 500+ profits,
will offset a weak Asia. The positive of the Asian impact is that it helps keep
inflation low at approximately 1 percent and has eased fears of an increase in
interest rates. In an environment of slowing corporate profits and stable
interest rates, stock selection becomes increasingly important. Our optimism for
the second half performance of the Portfolio, despite the prospect of a
relatively flattish market, is based on an emphasis in sectors showing strong
domestic growth such as retail, healthcare and technology. We think that over
the next six months there will be many more earnings disappointments. Investment
performance may be more dependent on avoiding the losers than identifying the
winners.

[PHOTO OF GARY CLEMONS]
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 Asian financial crisis and its effects on corporations across the world
continued to dominate economic news during the second quarter of 1998,
increasing volatility in financial markets around the world. Investors learned
the negative implications of global corporate interdependence, as the events in
Asia caused economists to predict a slowdown in global GDP growth for 1998. In
this environment, the International Stock Portfolio increased 11.81 percent* for
the six month period ended June 30, 1998, compared to the Morgan Stanley Capital
EAFE Index** return of 16.08 percent for the same period.
 
PERFORMANCE ANALYSIS
 
The Portfolio continues to benefit from a high exposure to European equities,
which represented approximately 65 percent of total assets during the period.
Equity markets were strong across Europe, as the region prepares for European
Economic and Monetary Union (EMU). The Portfolio's European financials fared
especially well over the period, as interest rate convergence in preparation for
the EMU led to lower rates in several nations. European financial equities were
among the Portfolio's top performers during the period, including the
Netherlands insurance companies, Aegon and International Nederlanden Group,
which advanced 97 percent* and 57 percent,* respectively and one of our largest
positions, French bank Banque Nationale De Paris ADR, appreciated 55 percent*
during the period.
 
    The Latin American markets struggled during the first half of 1998, as they
felt the residual effect of investor fear toward Asia. The Portfolio currently
holds approximately 7 percent in Latin American equities. 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. Weakness in these
markets has provided us with attractive investment opportunities. For example,
we have taken advantage of recent price weakness to add Anonima Telephonos De
Venezuela (CANTV) to the Portfolio. CANTV is the Venezuelan phone company, which
is trading at an attractive current P/E of 9x and offers a 6 percent dividend
yield potential (1). We continue to devote attention toward discovering further
quality investments in the Latin American region.
 
OUTLOOK
 
Turning toward Asia, it appeared in the first half of 1998 that the region's
financial crisis was far from over. Increased evidence of bad debts, foreign
exchange exposure, and political turbulence sent Asian equity markets even
lower. The Portfolio has approximately 7 percent of total assets invested in
Asian equities, with the majority invested in Hong Kong. With many share prices
having fallen over 75 percent in U.S. dollar, investment opportunities are
becoming more prevalent. However, caution is warranted when investing in the
region, hence our focus on companies with strong management, solid balance
sheets and sound long-term fundamentals.

Small Company Portfolio
 
PERFORMANCE UPDATE
JIM TATERA, CFA
CHIEF EQUITY PORTFOLIO
MANAGER
[PHOTO OF JIM TATERA]
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 9.43 percent* for the six month period
ended June 30, 1998. The Portfolio's benchmark, the Russell 2000 Growth Index**
returned 5.46 percent for the same period. The combination of faltering earnings
and declining interest rates has furthered what was already a large-cap, growth
oriented bias in the market. The dominance of the largest stocks in the first
half of the year was so substantial that in only two other half-year periods
since 1955 have small stocks done worse on a comparative basis.
 
PERFORMANCE ANALYSIS
 
Consumer Cyclical stocks, which include the retailers, and technology stocks
were the big positive contributors to performance in the Russell 2000 Growth
Index** during the first half of 1998, accounting for more than half of the
index return. The Energy sector showed the weakest absolute return and despite
its smaller weight in the index was the largest negative contributor to
performance. Health Care and Producer Durables also showed negative returns for
the period. The main culprit of these negative results was weaker than expected
earnings and the absolute decline in oil prices.
 
    The Portfolio's strong relative performance was due, in part, to avoidance
of earnings problems through our diligent analysis process. One area in
particular, which performed well, was the Consumer Cyclical stocks. This sector
is dominated by retailing companies like Pacific Sunwear of California
(specialty retailer to young adults and teens), Borders Group Incorporated
(superstore book retailer) and Tropical Sportswear International (men's
apparel). All three have performed very well year-to-date. Tropical Sportswear
International (TSIC) is typical of the companies we like to invest in. TSIC has
created a value-added business by manufacturing and supplying private label
garments for major retailers like Wal-Mart Stores, Dillards, Inc. and Federated
Department Stores. Originally focused on men's basic casual pants, TSIC has
expanded their product line. TSIC not only provides manufacturing and and
sourcing abilities to its retailers, but TSIC also provides a level of service
with unmatched delivery times and a comprehensive brand management program which
helps the retailers minimize the investment in inventory while maximizing the
in-stock supply of the garments. In other words TSIC has become an invaluable
member of the retailers' teams and has built strong relationships that can be
leveraged for future opportunities.
 
    United Rental, Inc. is another top performer for the Portfolio. United
Rental, Inc. rents and sells industrial equipment, parts and services. It is the
major consolidator in the industry with a proven management team that is growing
their business into a national brand franchise.
 
    Laggards for the period were an eclectic group led by Premiere Technologies
which fell in price as the company slowed its growth to consolidate its most
recent acquisitions. Premiere has developed a very strong product offering to
pursue the burgeoning telecommunications market; the consolidation of the
acquisitions is simply taking longer than expected.
 
    Two other areas, specifically the semiconductor and oil service areas, which
have been weak continue to show problems. Demand and pricing for semiconductors
remained weak, as well. The energy area has been especially hard hit with the
fall in oil prices. While we do have exposure to both areas, neither is a major
emphasis in the Portfolio today. We continue to keep abreast of developments in
companies in these areas with the anticipation of adding to our holdings when
our analysis shows a positive turn in the fundamentals.
 
OUTLOOK
 
We have been cautiously optimistic through the first half of 1998. Our caution
remains focused on the sustainability of company earnings and the potentially
overly optimistic estimates by Wall Street analysts. While the U.S. economy
continues to chug along, Europe has been strong and Asia weak. As it relates to
most
 
                                       20
<PAGE>
of the smaller growth companies in the Portfolio, the international markets and
events have less direct revenue or earnings impact than they have on the large
multinational companies. With that being said, the Asian problems are negatively
influencing a multitude of industries and will likely have a trickle-down effect
to the smallest companies. Thus our major concern today relates to earnings.
 
    Our approach focuses on those companies that exhibit superior revenue and
earnings growth potential with above peer profitability and strong management
vision. It is our belief that over time these issues will display higher
positive earnings surprise through accelerating operating momentum and would
then produce positive performance for the Portfolio. Today's valuations for
small growth companies are at historically low levels and will likely gain
investors' attention at some point. When that occurs small growth companies have
the ability to significantly outperform larger companies. The Portfolio is well
positioned by investing in small companies, which we feel have the ability to be
tomorrow's leading companies.

PERFORMANCE UPDATE

PORTFOLIO MANAGER
[PHOTO OF KENT WEBER]
The Maturing Government Bond 1998, 2002, 2006 and 2010 Portfolios seek as high
of an investment return as is consistent with prudent investment risk. The
Portfolios invest primarily in U.S. Government and Agencies zero coupon fixed
income securities with maturities near the 1998, 2002, 2006 and 2010 liquidation
dates of each Portfolio.
 
PERFORMANCE
 
For the six month period ended June 30, 1998, the Maturing Government Bond
Portfolios generated the following returns:

Ryan Lab's Inc. September 2010 Index...................    6.61 percent**
</TABLE>
 
PERFORMANCE ANALYSIS
 
Our investment activities continue to focus on tracking the performance of the
respective indices. To reach these goals, we continue to use a variety of
Government Agency securities. By selectively using these Government Agency
securities in concert with U.S. Treasury securities, the Portfolios benefit from
enhanced diversification and also from the receipt of additional income (over
that of U.S. 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:
 
<TABLE>

Maturing Government Bond 2006 Portfolio................        8.26 years
Maturing Government Bond 2010 Portfolio................       12.33 years
</TABLE>
 
OUTLOOK
 
At the time of this report, investors have been notified of the maturity of the
1998 Portfolio. The other Portfolios remain well situated, in our opinion. We
stand ready to handle an inherent increase in volatility that occurs due to the
low interest rate levels. We anticipate that the market will experience slower
growth and mild inflation, which sets the stage for a fixed-income friendly
year.

Value Stock Portfolio
 
PERFORMANCE UPDATE
GARY ASTER, CFA
PORTFOLIO MANAGER
[PHOTO OF GARY ASTER]
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 2.31 percent* for the period ended June 30,
1998. In comparison, its benchmark, the Russell 1000 Value Index,** earned 12.16
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
 
While progress has been made toward restructuring the Portfolio, results for the
first half of 1998 still lagged the benchmark Russell 1000 Value Index** by a
significant margin.
 
    Since most significant economic sector over-weightings, including Energy,
have been reduced, it is appropriate to identify stock selection as the main
issue. Philips Electronics, R.J.R. Nabisco Holdings Corporation and Morton
International, Inc. all suffered double digit percentage declines during the
first half of the year due to a variety of factors including earnings
disappointments, deteriorating fundamental business outlook and lack of
sufficient communication with investors. Two of these holding have been sold and
the other is under close review.
 
    The process of restructuring the Portfolio continues to move forward.
Several companies whose stocks meet our value requirements have been added to
the Portfolio. Among these additions are Food Lion, Inc., Diebold and Deluxe
Corporation. The stocks of each of these three companies share several common
investment attributes including a significant decline in the stock price prior
to purchase, experienced management teams and good business fundamentals
including strong balance sheets and good cash flow generation.
 
OUTLOOK
 
Looking ahead we expect that the Portfolio may eventually experience investment
return potential which may be at or near general market levels during rising
markets, better than market levels during declining markets and better than
market levels over a full market cycle.

Small Company Value Portfolio
 
PERFORMANCE UPDATE
GARY ASTER, CFA
PORTFOLIO MANAGER
[PHOTO OF GARY ASTER]
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 which are
low relative to their underlying value or future earnings and growth potential.
 
PERFORMANCE
 
For the six month period ended June 30, 1998, the Small Company Value Portfolio
returned 4.19 percent.* The Russell 2000 Value Index** returned 4.44 percent for
the same reporting 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
 
Sector returns were mixed for the Portfolio for the first half of 1998.
Relatively poor returns for stocks held in the Capital Goods and Transportation
sectors were offset by the strong showing in certain selections in Energy,
Health Care and Technology. Some highlights in the first half include: The
Learning Company, Inc. (up 84 percent*) which is consolidating the educational
software market with acquisitions made at attractive valuations. In June,
Nationwide Mutual Insurance Company announced that it is acquiring Allied Group
Incorporated (up 64 percent*).
 
    The turmoil in Asia, which began to hamper Portfolio performance in the
latter stages of 1997, continues. Holdings in the more economically sensitive
sectors such as Basic Materials and Energy were the most affected as commodity
prices dropped due to decreased demand from Asia. The concerns associated with
falling commodities are largely reflected in the market. Any sign of progress
out of Asia will likely cause renewed confidence in the worldwide economy and
solid performance from what are now inexpensive, economically sensitive stocks.
We will continue to monitor the progress of the Asian economies and determine
the affect on stocks held in the Portfolio.
 
OUTLOOK
 
The recent underperformance of small capitalization stocks relative to large
stocks has acted to widen the valuation gap that already existed at the
beginning of the year. We feel that the near-term and long-term outlook for
small capitalization stocks is very good.
 
    We continue to believe that the Portfolio's composition is positioned well.
The current holdings have solid fundamentals and are selling at reasonable
valuations.

The Global Bond Portfolio seeks to maximize 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 had a return of 5.04 percent* for the six month period
ended June 30, 1998. This compares to the Salomon Brothers World Government Bond
Index** return of 2.79 percent for the same period.
    In prior reporting periods, the Salomon Brothers Index+ was used as the
International Bond Portfolio's benchmark. The Salomon Brothers World Government
Bond Index** better fits the stated investment objective of the Global Bond
Portfolio. The Portfolio's performance will be compared to the Salomon Brothers
World Government Bond Index** going forward.
 
PERFORMANCE ANALYSIS
Global Commentary:
The major theme affecting global bond markets during the first six months of
1998 was the effects of the Asian crisis. Because of the turmoil in this region,
growth around the world was subdued, inflation remained in check, and bond
markets performed well in U.S. dollar terms. Bond yields fell across the board
with Sweden the best performing among developing countries. The U.S. dollar
experienced a slight decline, which helped returns for U.S. investors. Japan and
Australia were the only exceptions to this trend, as both bond markets turned in
negative returns.
    An overweight position in European bonds, notably the United Kingdom and
Sweden, helped propel performance during the first half of 1998. In these
markets, we maintained a long duration position (over 6.5 years vs. the index of
5.5 years), which was the right decision as most of the movement was at the long
end of the curve in these markets. Being out of Japan once again proved
favorable for the Portfolio, as this bond market continues to suffer from low
yields and an economy that is completely stalled. Likewise, the currency
weakened against the U.S. dollar.
U.S. Commentary:
Interest rates continued their moderate decline in the second quarter as concern
for strong domestic economic growth was offset by low inflation, global economic
and political instability. The yield curve flattened as rates on the 30-year
U.S. Treasury Bond declined 31 basis points to yield 5.63 percent while 2-year
notes declined only 8 basis points to yield 5.48 percent for the six month
period.
    Long U.S. Treasury Bonds were the best performing sector in the second
quarter. They benefited from the flattening of yield curve and a flight to
quality by bond investors. As bond investors became worried about global
uncertainties, their appetite for U.S. Treasury securities increased. This
demand, along with a smaller supply of U.S. Treasury securities drove bond
prices higher.
    Mortgage-backed securities performed very well, especially considering the
relatively low interest rate environment. Prepayment speeds and yield spreads
held steady, providing stable returns from this sector.
 
OUTLOOK
Global Outlook:
Continental Europe will likely experience a moderate pick-up in growth through
year-end, while the United Kingdom will likely see its growth slow down. This,
combined with a lack of inflationary pressures, creates a positive environment
for bond markets. We will continue to overweight the Portfolio with European
bonds. Because of slowing growth, however, UK sterling should come under
pressure. Therefore, we have hedged the UK sterling position into Deutschmarks.
    In the Far East and Pacific regions, the Asian crisis will likely create
sharply negative growth for all the regions economies. Because of this, we favor
the bond markets of Australia and New Zealand as yields move lower over the
remainder of 1998. In these two markets we have hedged the currency exposure
back into U.S. dollars.
    Japan's economy has deteriorated even further with yields at just over 1
percent. We see little value in this market. Therefore, no Japanese bonds will
be held in the Portfolio.
U.S. Outlook:
Interest rates will likely continue to be range bound and eventually grind lower
as the year progresses. Economic growth will likely begin to slow and inflation
will likely remain low as the Asian crisis, Japan and the strong dollar begin to
negatively affect our economy. The Federal Reserve will need to see signs of
slower growth and higher unemployment before they are willing to reduce
short-term interest rates. This could happen by early 1999, paving the way for
lower bond yields. This is positive for fixed income investors. In the
Portfolio, we will continue to own enough duration and take advantage of the
opportunities offered in the U.S. bond market.
 
    We look forward to reporting to you again at the end of the year.

Index 400 Mid-Cap Portfolio
 
PERFORMANCE UPDATE
TERI BRANDT
PORTFOLIO MANAGER
[PHOTO OF TERRI BRANDT]
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
 
For the six month period ending June 30, 1998, the Index 400 Mid-Cap Portfolio
returned 8.10 percent.* This compares to the S&P 400 MidCap Index,** which
earned 8.63 percent for the same period.
 
PERFORMANCE ANALYSIS
 
The Technology sector was the top contributor to the index during the reporting
period. The Technology sector rallied from its losses late last year and was the
strongest performer in the Portfolio. Financial, Transportation, Consumer
Staples and Consumer Cyclical sectors also contributed to the performance.
 
    Early in the reporting period, oil prices plunged to nine-year lows. This
profoundly hurt the Energy sector. Energy turned in a loss of more than 15
percent in the second half of the reporting period and was the worst performing
sector in the Portfolio. The sector was hurt by significant downward earning
revisions. Basic Materials followed the Energy sector as the second poorest
performer for the Portfolio.
 
OUTLOOK
 
We expect that the market will likely remain where it is if low interest rates,
low inflation and a strong domestic economy continue. In order for the market to
move higher, it is necessary to have growth in corporate earnings without the
threat of serious inflation. Year-to-date, the Technology sector has had the
greatest impact on the index return. The big question now: How will technology
stocks perform amid continued worries about weak Asian demand?
 
    As we look ahead, the picture for mid-cap stocks remains bright.

Macro-Cap Value Portfolio
 
PERFORMANCE UPDATE

[PHOTO OF MICHAEL J KELLY]
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 12.67 percent* for the six month period
ended June 30, 1998. This compares to the S&P 500 Index** return of 17.68
percent for the same period.
 
PERFORMANCE ANALYSIS
 
U.S. stock markets rose to new highs during the first half of 1998, despite
waves of bad news from Asia and an apparent slowdown in corporate profit growth.
Though the ultimate impact of Asian woes on the U.S. economy remains uncertain,
the market dismissed fears of a worst case scenario.
 
    Growth in earnings and a benign interest rate environment have been key
supports to continued equity market strength. Core information has managed to
decline even with falling unemployment and mostly flat capacity utilization
rate. More recently, overall inflation has been held in check by a stronger
dollar and lower energy prices. The combination of low unemployment, inflation
and interest rates continues to bolster consumer confidence as well as
consumer-based stocks. Year-to-date, retail stocks have gained 37 percent* and
consumer cyclical stocks are up 33 percent.*
 
    Drug stocks have also been strong this year. Relative to most large
multi-national corporations, the outlook for pharmaceutical companies appears
positive. Earnings growth trends have been very favorable with a number of major
drugs coming to market, price discounting to managed care is moderating, and
retail pricing and volumes are increasing. Although markets and currency in
Europe continue to be difficult, this group had no exposure to Southeast Asia.
In addition, further industry consolidation seems likely. Not surprisingly, drug
stocks outpaced the market during the first half (up 28 percent*), adding to the
group's 55 percent* 1997 increase.
 
    Stock selection among drug stocks helped the Portfolio outperform in this
sector. Warner-Lambert Company, one of the Portfolio's largest holding, gained
68 percent* during the first six months of the year. Sales of Warner's
cholesterol-reducing drug Lipitor surpassed the $1 billion mark. At the same
time, concerns raised in the fourth quarter regarding the company's innovative
diabetes drug, Ruzulin, abated substantially.
 
    Meanwhile, commodity-driven energy and basic industry stocks have gained
only 4 percent* and 7 percent,* respectively. Recovery in these sectors may take
some time, and near term earnings uncertainty remains high. However, our
investment approach has helped us to identify companies in these groups whose
stocks have declined disproportionately to their longer-term earnings and cash
flow prospects.
 
    For example, stocks of several traditional chemical companies appear
underpriced relative to our normalized cash flow forecasts. Dow Chemical
Company, a long-term underperformer, has shifted its mix of businesses as well
as corporate culture to focus on improving profitability and growth. The company
has disposed of poor businesses and is making value-added acquisitions. Prices
for key commodities appear to have bottomed; and Dow's realignment should
magnify the earnings impact of any improvement in pricing trends. Other
companies, such as DuPont, are pursuing exciting growth opportunities in life
science related areas. DuPont's commitment to pursing only high growth, high
return business is evidenced by its announced IPO of Conoco and acquisition of
Merck's stake in the DuPont Merck joint venture.
 
OUTLOOK
 
Looking ahead, we would note that the sustainability of domestic economic
momentum amid global disinflationary developments has been impressive. Still,
growth in corporate profits seems unlikely to rebound to 1997 levels in view of
softened global demand, a stronger dollar, domestic capacity growth, and
increasing wage pressures. Thus, our forecast calls for the recent slowdown in
operating earnings growth to persist through the end of the year.

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
 
For the six month period ending June 30, 1998, the Portfolio earned 9.27
percent* versus the Russell 2000 Growth Index** return of 5.46 percent for the
same period. Portfolio performance for the period was driven by stock selection
in the Technology and Consumer sectors. In the Technology sector, investments in
software and business services produced large gains while apparel and retail
dominated the Consumer Cyclical sector.
 
    During the second quarter 1998, the Micro-Cap Growth Portfolio returned
- -3.84 percent* compared to the Russell 2000 Growth Index** return of -5.74
percent for the same period. Strong stock selection in the Technology sector
(particularly software and networking companies) added value to portfolio
return.
 
PERFORMANCE ANALYSIS
 
A choppy and unpredictable second quarter ended with an upswing but created a
wider gap between the performance of the market's largest stocks and lagging
smaller issues. During the first six months of the year the S&P 500 Index+
gained 17.8 percent while smaller stocks (as measured by the Russell 2000
Index**) rose just 4.9 percent over the same period. As the Asian crisis
re-emerged, investors flocked to the perceived stability and liquidity of larger
stocks. Smaller-cap stocks languished for much of the second quarter but ended
the period on a strong note. Consumer stocks (especially apparel and specialty
retail) benefited from low interest rates and confident consumers. Technology
stocks, which sold off dramatically in May, rebounded strongly in the final
weeks of the quarter.
 
OUTLOOK
 
The Asian crisis has continued and there is no immediate end in sight. U.S.
companies have begun to feel the impact of Asia and corporate earnings are
declining. The earnings forecasts for the S&P 500 Index+ have been lowered in
each of the last ten months. We expect that analysts will continue to make
downward revisions on earnings estimates, particularly larger-cap stocks with
significant Asian exposure.
 
    It is our opinion that the earnings strength found in smaller-cap companies
will be more valuable as profit growth continues to slow in many larger-cap
issues. The expected earnings growth for the S&P 500 Index+ is 8 percent (and
trending lower) versus 13 percent for small-cap stocks. As Asia's problems
continue, we believe investors will move towards the more visible earnings
growth rate potential found in smaller-cap stocks. Specifically, we anticipate
consumer stocks will likely continue to be strong due to the low interest rate
environment. We also expect technology stocks, many of which have been
dramatically oversold, to rebound off their lows.

Real Estate Securities Portfolio
 
PERFORMANCE UPDATE
JOE BETLEJ, CFA
PORTFOLIO MANAGER
[PHOTO OF JOSEPH BETLEJ]
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).+
 
PERFORMANCE
 
The Real Estate Securities Portfolio was added to the Series Fund on May 1,
1998. The Portfolio's return for the period from May 1 (date of inception) to
June 30, 1998 was -3.80 percent.* This compares to the Wilshire Associates Real
Estate Securities Index (WARESI)** return of -1.47 for the same period.
 
PERFORMANCE ANALYSIS
 
The large gap between real estate securities returns and the broader equity
market has been frustrating for the public real estate companies and their
investors. After strong second half performance in 1997, some underperformance
could have been expected in the first half of 1998, but the breadth of the
difference has surprised analysts. Accordingly, we feel as a result of the
underperformance the market for real estate securities is oversold.
 
    What was behind the real estate market's poor performance in the first half
of the year? As we have moved to a more mature part of the real estate cycle,
some market fundamentals have changed. Our observation is that the stock market
doesn't like change. While most markets remain in balance, increasing fears of
new development have caused investors to question whether the strong operating
performance is sustainable. Also, at the beginning of the year, valuation
parameters suggested that real estate securities had moved ahead of their
underlying value, causing investors to become more concerned about returns
achieved on capital employed by this sector's companies. High return
expectations (20 percent plus) had to be dampened within this part of the real
estate cycle. Finally, a cloud hovered over the sector as the legislature
proposed various changes to the Real Estate Investment Trust (REIT) structure.
As the cloud lifted, the only change that withstood the congressional process
was that the grandfathered status of the Paired-Share was eliminated--affecting
only six companies.
 
OUTLOOK
 
We are confident that the continuation of the strong economic and interest rate
environment will provide fertile ground for the real estate securities market's
recovery. Company business models must further refine their focus on sustainable
earnings growth, particularly with a focus on internal growth prospects. Using
capital more efficiently will be more highly valued in a market where equity
capital has become scarce. More importantly, however, the sector must become a
very compelling value play. We believe that on the basis of dividend yield,
multiples relative to the broader market, return on capital, and the valuation
of the underlying assets, the market for real estate securities is now a
compelling opportunity for investors.
 
    The market forces are putting pressure on weaker management and we expect a
shake out of the lesser teams through consolidation. We are positioning the
Portfolio with companies that have a value creation focus, strong management
teams with strong alignment with shareholders, conservative capital structures,
and strong assets with appreciation potential. The market has discounted complex
stories and paired share REITs, creating strong buying opportunities within
these groups. We will take advantage of the discounts the market is offering to

 +The S&P 500 is a broad, unmanaged index of 500 common stocks which are
  representative of the U.S. stock market overall.
 *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 index contains 65
  securities of which 79 percent are equity and hybrid REITS and 21 percent are
  real estate operating companies (REOCS). Total return, dividend return and
  price return are available for this index series.

    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 16, 1997, the Board of Directors approved the addition of the Real
Estate Securities Portfolio. On April 24, 1998, Minnesota Mutual 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.
 
    On September 18, 1998 (the Target Date), the Maturing Government Bond 1998
Portfolio will be converted to cash and reinvested in another of the Fund's
Portfolios at the direction of the contract owner. If the contract owner does
not complete an instruction form directing what should be done with liquidation
proceeds, the proceeds will be automatically invested in the Money Market
Portfolio.

(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.
 
  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. 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.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
    For federal income tax purposes, the following Portfolios had capital loss
carryovers at June 30, 1998, 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:

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.
 
  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 June 30, 1998, the Bond and Mortgage Securities Portfolios
had entered into outstanding, when-issued or forward commitments of $1,525,078
and $5,602,617, respectively. The Portfolios have segregated assets, with the
Portfolio's respective custodians, to cover such when-issued and forward
commitments.
 
(3) INVESTMENT SECURITY TRANSACTIONS
    For the period ended June 30, 1998, the cost of purchases and proceeds from
sales of investment securities aggregated $174,959,356 and $161,882,905,
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 June 30, 1998 were as
follows:

(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 June
30, 1998, investments in securities of Bond, Asset Allocation, Mortgage
Securities, International Stock and Global Bond include issues that are
illiquid. The aggregate values of illiquid securities held by Bond, Asset
Allocation, Mortgage Securities, International Stock and Global Bond at June 30,
1998 were $15,765,624, $17,339,157, $10,201,260, $8,703,909 and $497,601,
respectively, which represent 9.9%, 3.0%, 9.1%, 2.6% and 1.9% 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 compliant. 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.

     December 31, 1993, respectively. 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.
