DEAR CONTRACT HOLDER,
 
We start 1998 optimistic about the long-term prospects of the U.S. economy and
financial markets but cautious about the next several months. The Asian
financial crisis that dominated the global investment environment in the second
half of 1997 promises to continue, posing significant risks to the economy and
investors. We look for the strength of the American consumer -- currently
enjoying rising real incomes, better employment opportunities, lower mortgage
rates and easy access to credit -- and the secular strength of the trend toward
capital spending on high technology to be sufficient to override the influence
of Asia on the U.S. In short, our best case scenario calls for the U.S. to
muddle through an unsettling period.
 
  As it has for several years, the country should continue to enjoy relatively
low interest rates and low inflation. But the new year will be different in at
least two ways, both of which can be expected to have direct bearing on 
investment opportunities.
 
  First, the economy should grow at a much slower pace. A slowdown in Asia will
depress capital goods spending and heighten import pricing pressure, putting a
damper on American corporations' pricing and profit growth at least through
1999. While the U.S. economy grew at an almost 4 percent rate in 1997, we look
for no better than 2 percent growth for the next two years -- with more than
half of the change attributable to the effect of the Asian fallout.
 
  Disappointing corporate profits is another given for 1998. Profits had begun
to slow last year even before the height of the Asian crisis. High current
valuations, however, seem to suggest that Wall Street has yet to recognize this.
The clash between Wall Street profit expectations and actual reported earnings
is part of the risk likely to be associated with equity investing in 1998.
Volatility, such as we experienced in 1997, should continue. In fact, the
overall market volatility is not likely to reflect the turmoil that individual
equities may experience. There will be a narrowing of the number of companies
able to meet analysts' expectations and this market will be absolutely
unforgiving to those companies that fall far short.
 
  Having stated this, however, we look for the Standard & Poor's 500 to return
about 9.5 percent, including the effect of reinvested dividends. This would be
an average return and in line with the historical long-term 10 percent return of
the stock market. On the heels of the last three 20 percent-plus return years,
an investor in 1998 may weigh the 10 percent prospect against a projected 7
percent total return on bonds and consider the difference insufficient
compensation for the inherent added risk. Adopting a more conservative posture
for the new year may be an appropriate step that you'll want to discuss with
your financial representative in the context of your long-term investing
objectives.
 
  To achieve a 9.5 percent return in 1998, the market's already high valuations
need to move even higher. We expect this to occur for a few reasons: the market
has so far demonstrated a certain complacency about the valuation levels;
American investors don't perceive there's anywhere better to go than the U.S.
equity market; and foreigners think of the U.S. market as a safe haven. All
should help support the market.
 
  Where, then, are the opportunities likely to be in 1998? Expect to see
disparate performance within industry sectors. For example, while the financial
services sector in 1997 tended to provide across-the-board strong performance,
in 1998 we expect the sector to include its share of winners and losers. Stock
selection will be key, too, to benefiting from the technology sector. Over the
long term, we are optimistic about technology and corporate America's continuing
commitment to it. It will be difficult to participate in a market return in 1998
without having some exposure to technology-based companies. One caution: Not all
technology companies will survive the year, which raises the risk of investing
in the sector.
 
  Conventional wisdom might argue in favor of remaining in the U.S. with your
investment dollars in 1998 and, more specifically, invested in small
capitalization companies with domestic lines of business. We'd challenge such
thinking as slower growth, slower inflation and even
 
                                                                               3

deflation and pricing pressures change the U.S. economic climate. The only real
antidote is growth, and from now on growth is more likely to be found outside
the United States. Today to participate in the growth from global business you'd
need to be exposed to large capitalization companies.
 
  International investing is a promising proposition in 1998, the Asian fallout
notwithstanding. In established markets, there are attractive opportunities to
be found in Europe and in Japan. Several Japanese companies have real cash flows
and even relatively attractive valuations. In addition, the effect of the Asian
problems has not been to discourage all investment into emerging markets; rather
investors have tended to divert investment dollars and business to other
increasingly attractive emerging markets in eastern Europe, the Middle East,
Africa and Latin America.
 
  With that as an economic backdrop, we encourage you to read the following
detailed report of your Portfolio; including an interview with your Portfolio's
management. Thank you for your continued support. We appreciate the opportunity
to serve your investment needs.
 
Sincerely,

MANAGEMENT SUMMARY
 
KEMPER MONEY MARKET PORTFOLIO
- ------------------------------------
 
  During the past 12 months, we had an economy which showed continued, robust
growth but with minimal inflationary pressures. In fact, the Federal Reserve
Board (the "Fed") acted on their concern about the pace of growth in the economy
by eventually raising interest rates in March of 1997. Since it is extremely
rare that you get an isolated movement in Fed policy, for example, just a one
time tightening or easing, the expectation was that it would be followed with
incremental interest rate increases. This did not occur because the principal
measures of inflation, the consumer and producer price indices, were measuring
benign levels of inflation. Additionally, in late October several financial
markets in the Far East took a downturn which diminished the U.S. economy's
prospects for 1998. Furthermore, investors flocked to the safety of U.S.
Treasuries which meant lower long-term interest rates.

  Based on our outlook for much of the past year, we expected that short-term
interest rates were going to remain flat or rise. Because of this we kept a
conservatively shorter maturity policy throughout a large portion of the year.
Overall, we had excellent performance. We were correct in our judgment about
interest rates early in the year and by keeping short average maturities
generally throughout the year, we were able to capitalize on market
opportunities as they arose. In the fourth quarter of 1997, we favored longer
maturities in order to take advantage of the upward bias in short-term rates
which occurred at year end.

  Looking forward to the first quarter 1998, we feel the Fed will remain on the
sidelines with rate stability similar to that of what we've seen recently. The
developing impact of Asian financial conditions on the continuing pace of U.S.
economic growth and tight domestic labor markets are the issues to watch in
early 1998.

KEMPER TOTAL RETURN PORTFOLIO
- ------------------------------------
 
  Overall, it was a good period for equity markets, although it was more
volatile than in recent years. In broad terms, large company stocks performed
the best early in the year and in the fourth quarter, while smaller stocks
performed the best during the middle of the year. We've gotten used to kinder,
gentler markets over the past 36 months or so, with steep moves only occurring
in an upward direction. That changed in 1997, but despite bouts of panicky
selling and "the party's over" rhetoric, the market finished ahead. The market
set a record with three consecutive years of 20 percent gains. If investors
didn't get spooked, they ended up with solid gains, which highlights the
importance of maintaining a long-term focus.

  We are "growth at the right price" investors. We look at price-to-earnings
ratios versus historical norms for given stocks or groups of stocks, make a
judgment as to how well they can grow earnings in the future, and then determine
if the stock's current price represents a good value. Ideally, we seek companies
that have good long-term prospects, but whose prices are down for a short-term
reason.

  The uncertainty created by the Asian currency problems in October prompted
many investors to move to high quality growth stocks, particularly in the health
care area, and pay just about any price to do so. We, on the other hand, buy
those types of stocks only when we believe the price is right. Consequently, we
had only core positions in some of the big-name growth stocks that continued to
gain regardless of the fundamentals. Additionally, our aggressive positioning,
which had worked for us for most of the fiscal year, worked against us in
October.

  We had a large weighting in financial stocks, and they had a strong run this
year despite a difficult October. We reduced our position in the financials
prior to the difficulties in the money center banks, but are waiting for a 
point to re-enter. Another area where we saw value was the telecommunication 
sector, specifically in the fourth quarter as AT&T had a major resurgence.

  Overall, we moved aggressively in and out of the technology sector as
valuations dictated. After they corrected in April, we increased our weighting
and enjoyed good performance as a result. We only had a neutral weighting in
tech stocks going into October when they were dumped across the board. We used
the opportunity to boost our weighting again given the good values we're seeing
for solid companies.

  Bonds have consistently made up about 35 percent of the portfolio during the
fiscal year. Around October, we boosted our weighting in government bonds, as a
percentage of the total, so that they are about 65 percent of the bond position,
up from 50 percent. That was to help increase liquidity as well as dampen
volatility. The majority of our bond assets not invested in governments has been
in high yield bonds to help provide some income.

  We're confident that we'll break into new highs in 1998. Of course there will
be bouts of uncertainty and turbulence, and future market conditions can not be
predicted with certainty, but we continue to enjoy relatively little upward
pressure on interest rates, plus modest economic expansion, solid earnings
growth and no inflation to speak of. With these factors in place, the
environment remains very positive for both stocks and bonds. We think that
investors who can maintain a long-term focus should continue to benefit.

MANAGEMENT SUMMARY
 
KEMPER HIGH YIELD PORTFOLIO
- ------------------------------------
 
  It was another strong year for high yield bonds, but we began to see some
intermittent bouts of volatility enter the market. High yield supply grew
phenomenally, reaching record levels, and was met with strong demand. Much of
the new supply, however, was lower quality issues (B- or lower). Since yield
spreads in the market remained very tight, investors looked to these lower
quality issues for higher rates of return.

  Strong corporate earnings, a strong economy with benign levels of inflation,
and a low level of high yield defaults created a strong high yield market and
fueled demand for lower quality, high yield bonds, in particular. For the most
part, lower-quality issues outperformed B and BB-rated high yield bonds during
the year. However, as economic and market events impacted the high yield market,
these lower-rated issues were hurt more than the higher quality bonds.

  In March, the Fed increased short-term rates, which in-turn initiated a sharp
sell-off in the securities markets and a widening of high yield spreads. The
high yield market was hit harder than it might have been if Federal Reserve
Board Chairman Alan Greenspan had not expressed his concern about the market's
bull run. The high yield bonds that experienced the greatest losses were the
riskier issues--those C-rated and lower. However, the impact of Greenspan's
remarks and the subsequent rate increase were short-lived and relatively
minimal. The high yield market, along with the other securities markets, were
well into recovery as quickly as April.

  We managed the Portfolio defensively early in 1997 because we believed that
the economy was gaining momentum and that the Fed would most likely tighten
interest rates. We reduced the level of BB-rated bonds (the highest quality
securities that are still considered to be high yield) and maintained a similar 
composition for the remainder of the  year.

  In addition to altering the credit quality of the portfolio, we were
underweighted in deferred interest bonds. These securities have a longer
duration and tend to perform poorly in a rising interest rate environment. The
shorter duration that resulted from the sale of these deferred interest bonds
helped the Portfolio's performance as interest rates increased in March.

  The Portfolio is still overweighted in cyclical holdings because of their
long-term earnings potential. However, we continued to move away from issues of
companies that we considered to be deeply cyclical and focused on adding issues
from companies that are less cyclical, or have some degree of independence from
changes in the overall U.S. economy.

  We're quite optimistic about the long-term outlook for the high yield market.
We anticipate a pick-up in defaults as some of the lower-quality new issues
begin to age. However, we believe that the current economic environment combined
with the low rate of defaults are both positive indicators. We will continue to
focus on adding issues from what we believe are stable, fundamentally strong
companies.

KEMPER GROWTH PORTFOLIO
- ------------------------------------
 
  Overall, it was a great period for stocks, particularly large company stocks.
Through most of the year, stocks benefited from a near idyllic
environment--solid economic growth, rising corporate profits, low interest rates
and virtually non-existent inflation. You couldn't ask for a much better climate
for business.

  In absolute terms, the Portfolio did well. In comparison to the market,
however, our performance was disappointing. An overweighting in mid-cap stocks
in the first quarter was largely responsible for a slow start for the Portfolio
when compared to the S&P 500, and we weren't fully able to make up the
difference by the end of the year. However, we're encouraged because the changes
we made early in the year contributed to much-improved performance later.

  These changes were almost entirely the result of our investment philosophy of
"growth at the right price," or "GARP." As GARP investors, we look for high
quality, solidly-managed companies with projected growth rates that are greater
than the overall market, and we try to buy them as cheaply as possible. Ideally,
we seek stocks that are mispriced due to very short-term fundamental problems or
negative market psychology. In short, we try to identify stocks of high quality
companies that are down for the wrong reasons.

  We reduced our mid-cap stock exposure in favor of large cap stocks, which are
generally higher-quality companies and offer more predictable earnings growth.
At the same time, in an effort to diversify, we concentrated on three major
areas: health care, finance and technology. Health care purchases were
concentrated in pharmaceutical companies, and in finance we diversified into
banks, insurance companies and financial firms.

  In April, technology stocks came under tremendous pressure because of concern
over earnings outlooks.

<PAGE>   7
MANAGEMENT SUMMARY
 
We believed a lot of this was overdone, so we took a major position in
high-quality technology companies. Our technology weighting helped the Portfolio
perform very well through the summer as these stocks rebounded.

  Currently, there are a number of reasons for continued optimism regarding
stocks. Our economy is solid, we've got good income and employment growth,
consumer sentiment is good and there seems little evidence that interest rates
will increase dramatically. So all the things you need for good consumption are
there. We've therefore been focusing on retailers.

  American businesses are experiencing good corporate growth and profitability.
Also, it seems that every Board of Directors in the U.S. is concerned with
adding shareholder value. They're increasing dividends, buying back shares,
spinning off divisions . . . even the politicians are getting into the act with
a balanced budget agreement and tax reform. It's a very compelling environment
for investors.

  The only sticky point is valuations. They are relatively high taken as a
whole, and that may lead to increased volatility as investors look to get the
most potential bang from their investment buck. We believe volatility helps
provide us with opportunities to buy good companies at good values and help
control risk by buying high quality companies when their prices are low.
Therefore, while volatility is unsettling, and while no management strategy can
be guaranteed, our approach is designed to make volatility pay off for
investors.

KEMPER GOVERNMENT SECURITIES PORTFOLIO
- --------------------------------------
 
  Government bonds, and in particular mortgage securities, performed well during
the year. The Fed raised interest rates but the impact of the tightening on the
market was brief and relatively minimal.

  Early in 1997, strong economic reports surfaced and Federal Reserve Board
Chairman Alan Greenspan reiterated his concern about the values of securities
and about the potential for a rise in wage inflation. We began preparing for a
possible rate hike in January, by shortening the Portfolio's duration to below
that of its peer group average, sold Treasury notes and purchased GNMA
mortgages. We believe our shortened duration and increase in mortgage holdings
supported the Portfolio's performance through the Fed's tightening.

  While economic growth remained somewhat strong, even after the Fed tightening
in March, inflation remained uncharacteristically low. The government market
along with the broader fixed-income market began recouping losses experienced
with the Fed's interest rate increase as inflation fears continued to be
unconfirmed. As economic growth slowed and the need for further Fed tightening
diminished, the market and the Portfolio rebounded very quickly and the 
Portfolio enjoyed positive returns.

  By April the markets were in recovery from the Fed's tightening and inflation
remained relatively benign despite continuing growth in the economy. To take
advantage of this environment, we began adding Treasuries back into the
portfolio. For the remainder of the year, market yields fluctuated with the
release of varying economic data but generally trended lower. Inflation never
became problematic and bonds performed positively.

  We are cautious about the prospects for the market and have reduced the
duration of the Portfolio to reflect this caution. The current economic
environment--benign inflation and moderate growth--is a particularly good one
for bonds, but low bond yields currently reflect these conditions, warranting a
more neutral market posture. We also believe that within a global context, U.S.
Government bonds and mortgage securities are a reasonably priced asset class and
may do well on a relative basis.

MANAGEMENT SUMMARY
 
KEMPER INTERNATIONAL PORTFOLIO
- ------------------------------------
 
  In Europe, we saw the continuation of modest, but consistent economic
expansion while Japan saw little forward progress and in Southeast Asia,
economic growth was stalled as most countries experienced currency depreciation
on higher interest rates. Latin American economies were generally positive
however, as domestic markets continued to recover from the downturn of two years
ago.
 
  Within the economic environment that I described, we emphasized those markets
and market segments that had the highest growth potential and the least amount
of economic, political or valuation risk. With this criteria in mind, the
Portfolio was consistently overweighted in Europe, increasingly underweighted in
Japan and, especially during the second half of the fiscal year, meaningfully
underweighted in Southeast Asia. Where we did continue to invest in Asia, we
stayed focused on high-quality companies that had some ability to weather the
storms which started in those markets during the summer months and came to a
head in late October.
 
  In Europe, our focus on economies and sectors benefiting from the lower
interest rates was an important theme. The Spanish and Italian markets offered
very good value as those economies restructured to meet the European Monetary
Union (EMU) requirements. The Netherlands, where we found companies that
combined strong management and consistent earnings, was also an attractive
market. In Latin America we focused primarily on Mexico where we selected
companies with broad exposure to the domestic market that are playing a strong
role in the country's economic recovery. In general, we have emphasized
companies that have demonstrated an ability to compete globally and that
generate high relative returns on equity and capital in their industries. We
have also worked to identify mid-cap companies that have strong local
franchises. Utilizing a proprietary market valuation model we detected an above
average level of risk in the Asian markets early in the new year. As a result,
we were consistently underweighted in the Asian markets that saw such large
drops and plan to be very conservative with our investments in the region.
 
  Our hedging during the period was a net positive, but more so during the first
half of the fiscal year. We had a larger hedge during the first half when the
dollar was exerting most of its strength. We began cutting down the size of the
hedge during the second half of the year and finally eliminated the hedge in
October.
 
  We continue to think that growth in the western economies will be good,
although there may be some modest trimming as a result of the problems in Asia.
We think that monetary policies will continue to support economic expansion and
that interest rates in a low inflationary environment will continue to underpin
above average equity valuations. Companies should be able to generate consistent
growth in earnings and attractive returns on capital going forward due to this
positive economic environment.
 
  We don't see any early solutions to the fundamental problems in Japan and
Southeast Asia but we do think combined world financial support and economic
growth elsewhere will eventually lead to a recovery in that region.

KEMPER SMALL CAP GROWTH PORTFOLIO
- ------------------------------------
 
  After three excellent years of performance in the Kemper Small Cap Growth
Portfolio, we continue to maintain our disciplined focus on timeliness,
fundamentals, and valuation as we head into 1998. The current interest rate
environment combined with potential earnings problems related to the Asian
crisis have led us to maintain a focus on industries that exhibit predictable
earnings growth. We continue to find timely stocks with good fundamentals and
appreciation potential in the broadcasting, consumer, finance, and healthcare
sectors. These sectors should benefit from a moderate growth, low interest rate
economic scenario.
 
  Changes to the Portfolio over the past couple months include trimming our
exposure to the technology sector, which helped performance in the fourth
quarter of 1997. Technology companies tend to do a considerable amount of
business in Asia, whereby downward earnings revisions may impede stock price
performance over the near term. However, we expect to find buying opportunities
in this group at somewhat lower prices later in the year.
 
  Other noteworthy changes in the Portfolio include adding to our broadcast and
finance holdings. Broadcast holdings such as Jacor Communications, Hearst-Argyle
Television, and Outdoor Systems should benefit from the strong advertising
environment in the radio, television, and billboard industries. Financial
holdings, in particular savings and loans and REIT's, could do particularly well
in the current environment. Major holdings here include First Union Real Estate
Investments, People's Heritage Financial Group, Spieker Properties, and
Commercial Federal.

MANAGEMENT SUMMARY
 
  Small company stocks have trailed their large company counterparts over the
past couple years and while it is hard to predict if or when this trend will
reverse, we continue to find that small companies can offer greater earnings
growth at lower valuations. This combination has historically made for a good
investment climate for investors on a risk versus reward basis, and in this
pursuit, we intend to maintain our disciplined investment approach in the Kemper
Small Cap Growth Portfolio in 1998 and beyond.

KEMPER INVESTMENT GRADE BOND PORTFOLIO
- --------------------------------------
 
  The Portfolio performed relatively well given the significant market and
economic events that occurred during the year. Performance was temporarily
hindered by the Federal Reserve Board's increase in short-term interest rates
near the end of March, but from May through September, the Portfolio performed
well. In late October, there was a global equity market sell-off that impacted
the investment grade corporate market. The Portfolio struggled with the market,
and gave back some of its earlier gains. Despite the fact that the Fed raised
interest rates in late March and the economic crisis in Southeast Asia spawned a
global equity market sell-off on October 27th, on a year over year basis
corporate bonds gained.
 
  Federal Reserve Board Chairman Alan Greenspan's implied threat in early
October that the Fed was prepared to raise interest rates before the end of 1997
was squashed in late October when several markets in the Far East took a
downturn. This sell-off was dramatic and initiated declines in the corporate
bond market as well. Investors flocked to U.S. Treasuries, which rallied through
the end of October.
 
  As U.S. economic growth continued after the first quarter, and it was clear
that inflation was not becoming a problem, we extended the Portfolio's duration 
by redirecting the higher levels of cash from earlier in the year back into 
corporate bond and Treasury investments. Both of these asset classes performed 
very well into October as market yields moved lower in response to the positive 
economic environment.
 
  In early October, we began to reduce our exposure to our most illiquid and
volatile corporate assets because some of these issues had significant foreign
exposure. This reduction in foreign exposure helped the Portfolio when the
global market decline occurred, while our larger allocation to Treasuries help
offset losses in the corporate sector.
 
  Moving forward, we are optimistic about the prospects for investment-grade
bonds. The fundamentals of the market remain healthy: corporate earnings are
strong, the economy is robust and inflation is negligible. Corporate bonds
shrugged off the impact of the March rate hike and rallied for much of the year.
We anticipate that investment grade corporate bonds will be well into recovery
from the October decline by the end of the year, and we believe the Portfolio is
well positioned to benefit from such a recovery.

MANAGEMENT SUMMARY
 
KEMPER VALUE PORTFOLIO
- ------------------------------------
 
  Overall in 1997, the Portfolio's holdings of financial stocks, particularly
regional banks, specialty financial services and insurance companies enhanced
performance this year, as did stocks in the energy area and selected cyclical
industries. In addition, the volatile nature of the market in the second half of
the Portfolio's fiscal year provided us excellent opportunities to sell a number
of stocks at profits while buying others at attractive prices. We were well
positioned due to our diversification and were prepared so that a correction in
one sector or stock would not have a tremendous impact on the Portfolio. Also,
we believe low Price/Earnings ratio (P/E) stocks provide the opportunity to
perform better than higher P/E stocks in volatile markets.
 
  The market was led in 1997 by the Blue Chip "Nifty Fifty" stocks. Most of the
"Nifty Fifty" stocks, which are the most favored by institutions at this time,
have high P/Es. Because we are value investors, we don't own them and therefore
haven't participated in their performance. The upside to a "Nifty Fifty" market
is in essence that most stocks are not as high as the averages might suggest.
Therefore, there are values available to patient investors. As contrarian value
investors, we continue to focus our research efforts on laggard stocks and
groups currently down in price due to short-term fundamentals or other problems
perceived by the market where our research suggests that over time fundamentals
will improve.
 
  The market has become increasingly intolerant of fundamental disappointments,
such as lower-than-expected earnings, which is a marked change from a year ago.
Investors have become a little more risk-averse in this environment. That's good
for us because it increases our opportunities to buy good stocks at value
prices. Moreover, we have been fortunate in that the portfolio has not held
securities that have suffered serious price declines.
 
  Although the securities held have changed, the characteristics of the
Portfolio have not. The stocks we own have dividend yields greater than the
market, P/Es lower than the market and earnings growing faster than the market.
The last half of the year, with its volatility, provided us an excellent
opportunity to sell stocks at advantageous prices. What we sold during the time
were stocks that we thought had realized their potential or where valuation
and/or fundamental risks had increased.
 
  I mentioned earlier that financial stocks, particularly regional money center
banks and specialty financial services stocks, did very well for the Portfolio
this year. General Re Corp. is one that performed well. General Electric,
Bristol-Meyers Squibb, and Ford Motor Co. also had fundamentals that came
through better than expected and have performed better than the market. Exxon
Corp. is one of our favorite energy stocks that did well for the Portfolio this
year. We prepared this Portfolio for the volatility we expected in '97, and
while some stocks underperformed, the Portfolio did not experience substantial
losses in any of its holdings.
 
  During the year, we increased the Portfolio's interest in stocks we
particularly liked, such as Aluminum Company of America (ALCOA), Xerox, AMP
Inc., Chase Manhattan Bank and American Home Products. Additionally, Texaco was
added as a new position during 1997. The combination we look for is companies
whose earnings and dividends are rising faster than the market, but whose prices
are at a discount.
 
  We like the diversification of the Portfolio and the changes that were made in
recent months. We'll continue to seek out excellent value opportunities,
adhering to the discipline of conservative, risk-adverse, value-oriented,
contrarian investing. To this end we have developed a long watch list.

MANAGEMENT SUMMARY
 
KEMPER SMALL CAP VALUE PORTFOLIO
- ------------------------------------
 
  Overall, 1997 turned out to be more volatile than recent years. On several
days the Dow Jones Industrial Average gained or declined more than 100 points.
However, the market's volatility helped the Portfolio in the sense that it
created opportunities for value investors like us. We look for stocks that are
out of favor with investors because the market underestimates their value or
overlooks their potential. When the market declines, that simply broadens the
pool of undervalued stocks we can choose from. In addition, the prices of
underappreciated stocks tend to be lower than those of in-demand stocks.
Therefore, when the market declines, although there are no guarantees, our
stocks are apt to fall less because their prices are already depressed.
 
  From a strategic standpoint, we made a number of moves to capitalize on
opportunities in undervalued sectors. For example, we increased our holdings in
financial stocks, where valuations remain attractive. We bought several
sub-prime mortgage companies--companies that provide mortgages to people with
less than perfect credit ratings. As always, we sought companies with solid
fundamentals, good growth potential and attractive valuations.
 
  Technology was another sector that presented opportunities. Technology stocks
declined due to earnings concerns in the spring, rallied strongly throughout the
summer, and sold off again in October when economic problems in Asia came to the
fore. They hindered performance at the end of the year even though we were
underweighted in the sector, but we are looking at them as an opportunity longer
term. We believe we're in good stocks and the market is simply not realizing
their potential right now, which fits right into our value philosophy. If they
continue to decline, we should be able to increase our holdings in strong,
competitive technology companies at value prices.
 
  As for 1998, we'll continue to apply our value strategy in our selection of
stocks. We don't foresee huge changes to our sector allocations. Rather, we'll
use volatility within each sector as an opportunity to execute our strategy of
buying inexpensive stocks and selling them when they become fairly valued. As
usual, valuations will play a bigger part in our stock selection than will
economic forecasts or interest rate trends.
 
  There are a couple of reasons why we believe small caps will be the place to
be in 1998. First, although a lot of money is currently pouring into the S&P 500
as investors emphasize the relative safety of big cap stocks, small caps tend to
have far less exposure to the Far East than large caps. Also, large cap stocks
have led the market for most of the last three years. Valuations on small
company stocks are compelling in comparison. At some point, investors should
recognize this value and begin focusing on small company stocks as a way to seek
higher returns. If so, we believe the Portfolio should be well positioned to
provide strong potential performance. And in the meantime, our value strategy
should also present less risk to shareholders' money than an emphasis on
high-flying growth stocks.

KEMPER VALUE+GROWTH PORTFOLIO
- ------------------------------------
 
  The 1997 market didn't seem very concerned about value for much of the year -
investors just continued to bid up the prices of big, brand-name companies.
There were two reasons for this. First, uncertainty about the direction of
interest rates during the first part of the year prompted investors to favor big
companies whose bottom lines tend to be less affected by interest rate changes.
Second, concern over the impact of Asia's problems during the last months of the
year prompted a "flight to safety," and again large cap, brand-name companies
benefited.
 
  The year began with two quarters of strong growth, and with a parallel run-up
in interest rates. This increase in rates was caused by fears of a major Federal
Reserve Board ("the Fed") rate action. As a result, the financial services
sector was an outstanding performer for the Portfolio.
 
  We found growth at reasonable prices in the second quarter of 1997 in
technology, the largest sector in the Portfolio at 22.9 percent on December 31,
1997. The entire sector was under pressure at the end of the first quarter due
to fears of inventory overhang and intense competition. We believed these
concerns to be largely unwarranted, and added to our technology stock positions.
 
  Technology stocks, along with the rest of the market, rallied strongly during
the second and third quarter of 1997, as data positive for the U.S. economy
reassured investors. Indications of sustainable growth, low inflation, and
declining interest rates created a favorable environment for stocks, a climate
which continued through October.
 
                                                                              11
 
<PAGE>   12
MANAGEMENT SUMMARY
 
  Believing the health care sector to be overvalued by the market, we took the
opportunity to sell some of the particularly high-flying issues and established
new positions in more value-oriented issues in the sector, which should enhance
long-term Portfolio results.
 
  In October, the market's powerful rally was suddenly reversed by emerging
problems in Asia, which, as we mentioned earlier caused a "flight to safety."
The Portfolio was particularly hurt by its large exposure to technology, which
took the worst of the market's fear. However, we believe that tactic may in the
end reverse itself as many of these companies are multi-nationals with heavy
exposure to Asia. We prefer to look for growth without paying exorbitant prices.
The market hasn't rewarded this approach yet, but we believe it will in the long
term.
 
  Toward the end of the year, we increased the growth percentage of the
Portfolio from 60 percent to 65 percent. This action relates to our outlook for
the economy and interest rates.
 
  Favorable to growth stocks is that earnings growth is expected to slow in 1998
resulting from concerns regarding the impact of the problems in Asia; reduced
opportunities to increase industrial productivity (since many companies have
already made a lot of improvements); and diminished tax incentives as a stimulus
to industry. Slower earnings growth tends to be good for growth stocks, as
economically sensitive types of stocks typically take the brunt of earnings
declines. If earnings slow, the market will be willing to pay a premium for what
growth it can find, making growth stocks more attractive. Regardless of whether
the higher returns will be in growth stocks or value stocks in 1998, the
Portfolio should be positioned to benefit from opportunities in both worlds.

MANAGEMENT SUMMARY
 
yet, but we believe it will in the long term.
 
  Prior to November, the portfolio reduced exposure to Asian markets, resulting
in a relatively light international weighting. However, we feel a ripple effect
also impacted Latin America and Europe as well and we intend to monitor
international markets closely, looking for good values and signs of a continued
downturn. In addition, we will likely allocate more to small companies. They
have been left behind in favor of large, richly priced companies and there may
be some fast-growers being ignored by overly cautious investors.
 
  On the fixed-income side, we have maintained a conservative structure with
approximately a 2.5 year duration comprised mostly of treasuries. This helped
dampen the volatility of the Horizon Portfolios, as intended when they were
formed. Unfortunately the short duration did not allow us to benefit from the
appreciation in price of the long end of the fixed market (i.e., the decline in
interest rates), since the yield curve flattened and didn't benefit the short
end of the curve where we are positioned.

KEMPER BLUE CHIP PORTFOLIO
- --------------------------
 
  Our philosophy has always been "bottom up" stock selection. Rather than
focusing on economic conditions or entire sectors, we tend to choose stocks
based on their individual merits, and seek those that offer above-average growth
prospects, but are selling at what we believe to be attractive prices.
 
  When the market is volatile, that usually gives us opportunities to buy good
stocks on a dip. Unfortunately, our disciplined approach to valuations worked
against us over a period of months in the third quarter. The expensive stocks
just got more expensive, and the less expensive stocks got less expensive. This
was due to the market's volatility, particularly in light of the problems
experienced by Pacific Rim economies, which made many investors nervous. The
response was a flight to big, brand-name stocks that people believed were safer,
and they would pay any price to do so. The lofty valuations that resulted made
us hesitant to buy companies like Coke, Merck or Pfizer. There's not a lot of
upside in stocks priced that highly, and they are susceptible to a big plunge on
any bad news. Regardless, the market continued to bid them up, and we didn't
participate as fully as we would have liked.
 
  In light of the earlier turbulence in the Pacific Rim and as a function of
emphasizing domestic stocks, we've reduced our exposure to cyclical companies,
reducing our capital goods stocks and cutting our basic industry exposure in
half.
 
  Financial stocks were an area of solid performance. We traded around them
efficiently and were proactive when they reached our targets. Our overweighting
in retail also helped provide a good boost for the portfolio.
 
  Although railroad companies were a bit disappointing during the year,
transportation stocks as a whole are now even cheaper with solid, good quality
companies available for very attractive prices. So we're maintaining an
overweight in transportation.
 
  We continue to like consumer cyclicals and the radio area as well as
healthcare. We've been moving into service areas and have eliminated big names
because they look hugely expensive and don't appear to have much upside left. As
we've gotten somewhat defensive we've built food and staples positions.
 
  The economy's growth, coupled with an environment of low inflation and low
interest rates, offers many individual companies the potential to experience
gains. We intend to maintain strict attention to valuations and try to find
these kinds of companies when they are priced attractively. At some point, the
market is going to realize that there are a number of bargains on solid growth
companies out there, and that's when we believe this Portfolio will benefit the
most.

MANAGEMENT SUMMARY
 
KEMPER GLOBAL INCOME PORTFOLIO
- ------------------------------
 
  In the second half of the year, global bonds performed well in their local
currency terms. For example, the third quarter return for the Solomon Brothers
World Bond index was 3.01 percent, while in the fourth quarter it was 2.46
percent. The same index in U.S. dollar terms was 1.27 percent and 0.21 percent
for the third and fourth quarters, respectively. These returns were due to the
strength of the U.S. dollar as a flight to quality from the Asian currency
crisis boosted the existing uptrend.
 
  The Global Income Portfolio started operations on May 1, 1997 and began
investing first in the U.S., Canada, UK, New Zealand and the Netherlands. Next,
we added the German and Swedish markets and reduced our positions in the U.S.
and UK. The German and Canadian exposures were increased in August while in
September, we again reduced the Canadian and U.S. markets and added Australian
and Japanese markets.
 
  After an increase in October, our U.S. exposure was once again reduced in
November and Canadian was sold in order to increase Australian, New Zealand and
the Netherlands markets. In December, some changes were made in Europe and the
U.S. was further reduced to buy Canada. At the end of the year, we were
overweighted in Australian, New Zealand and UK markets, and underweighted in
U.S., Japan and peripheral European markets.
 
  We maintained our long-term approach and remained committed to government and
supranational bonds with a very high credit quality. The Portfolio was 83
percent in AAA bonds and the rest in AA. The average duration was just under 5
years through the period.
 
  The bond markets of most developed nations benefited from the flight to
quality due to the Asian crisis. Some markets such as Australia and New Zealand
did suffer due to their currency weakness.
 
  While bond yields have decreased, growth and inflation expectations have also
decreased. This, combined with the likelihood that the Asian countries will
recover at a slower pace than Mexico in 1995 due to the private sector debt
problem, means that bonds are not overpriced and the disinflationary forces will
continue in the medium term. Central banks are unlikely to raise rates in the
next quarter with the Bundesbank most likely to be the first, in the run up to
the EMU.

INVESTORS FUND SERIES
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolios of investments, of the Kemper Money Market, Kemper
Total Return, Kemper High Yield, Kemper Growth, Kemper Government Securities,
Kemper International, Kemper Small Cap Growth, Kemper Investment Grade Bond,
Kemper Value, Kemper Small Cap Value, Kemper Value+Growth, Kemper Horizon 20+,
Kemper Horizon 10+, Kemper Horizon 5, Kemper Blue Chip and Kemper Global Income
Portfolios, comprising the Investors Fund Series as of December 31, 1997, and
the related statements of operations and changes in net assets for the periods
indicated therein and the financial highlights for each of the fiscal periods
since 1993. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the Portfolios of the Investors Fund Series at December 31, 1997, the results
of their operations, the changes in their net assets and the financial
highlights for the periods indicated therein in conformity with generally
accepted accounting principles.

1    DESCRIPTION OF THE
     FUND                    Investors Fund Series (the "Fund") is an open-end,
                             diversified management investment company organized
                             as a business trust under the laws of

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

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. The securities of the Portfolios (excluding
                             the Kemper Money Market Portfolio) that are traded
                             on a domestic securities exchange or securities
                             listed on the NASDAQ National Market are valued at
                             the last sale price on the exchange or market where
                             primarily traded or listed or, if there is no
                             recent sale, at the last current bid quotation.
                             Portfolio securities that are primarily traded on
                             foreign securities exchanges are generally valued
                             at the preceding closing values of such securities
                             on their respective exchanges where primarily
                             traded. A security that is listed or traded on more
                             than one exchange is valued at the quotation on the
                             exchange determined to be the primary market for
                             that security by the Board of Trustees or its
                             delegates. All other securities not so traded or
                             listed are valued at the last current bid quotation
                             if market quotations are available. Fixed income
                             securities are valued by using market quotations,
                             or independent pricing services that use prices
                             provided by market makers or estimates of market
                             values obtained from yield data relating to
                             instruments or securities with similar
                             characteristics. Equity options are valued at the
                             last sale price unless the bid price is higher or
                             the asked price is lower, in which event such bid
                             or asked price is used. Financial futures and
                             options thereon are valued at the settlement price
                             established each day by the board of trade or
                             exchange on which they are traded. Over-the-
                             counter traded fixed income options are valued
                             based upon prices provided by market makers.
                             Forward foreign currency contracts and foreign
                             currencies are valued at the forward and current
                             exchange rates, respectively, prevailing on the day
                             of valuation. Other securities and assets are
                             valued at fair value as determined in good faith by
                             the Board of Trustees.
 
                             The securities of the Kemper Money Market Portfolio
                             are stated at amortized cost, which approximates
                             market value. In the event that a deviation of 1/2
                             of 1% or more exists between the Portfolio's $1.00
                             per share net asset value, calculated at amortized
                             cost, and the net asset value calculated by
                             reference to market quotations, or if there is any
                             other deviation that the Board of Trustees believes
                             would result in a material dilution to shareholders
                             or purchasers, the Board of Trustees will promptly
                             consider what action, if any, should be initiated.
 
                             CURRENCY TRANSLATION. The books and records of the
                             Fund are maintained in U.S. Dollars. All assets and
                             liabilities initially expressed in foreign currency
                             values are converted into U.S. Dollars at the mean
                             between the bid and offered quotations of such
                             currencies against the U.S. Dollar as last quoted
                             by a recognized dealer. If such quotations are not
                             readily available, the rates of exchange are
                             determined in good faith by the Board of Trustees.
                             Income and expenses and purchases and sales of
                             investments are translated into U.S. Dollars at the
                             rates of exchange prevailing on the respective
                             dates of such transactions. The Portfolios include
                             that portion of the results of operations resulting
                             from changes in foreign exchange rates with the net
                             realized and unrealized gain (loss) on investments.

NOTES TO FINANCIAL STATEMENTS
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date (date the order to buy or sell is
                             executed). Dividend income is recorded on the
                             ex-dividend date, except that certain dividends
                             from foreign securities are recorded as soon as the
                             information is available to the Fund. Interest
                             income is recorded on the accrual basis and
                             includes discount amortization on all fixed income
                             securities and premium amortization on
                             mortgage-backed securities and money market
                             instruments. Realized gains and losses from
                             investment transactions are reported on an
                             identified cost basis.
 
                             Several of the Portfolios may purchase securities
                             with delivery or payment to occur at a later date.
                             At the time a Portfolio enters into a commitment to
                             purchase a security, the transaction is recorded
                             and the value of the security is reflected in the
                             net asset value. The value of the security may vary
                             with market fluctuations. No interest accrues to
                             the Portfolio until payment takes place. At the
                             time the Portfolio enters into this type of
                             transaction it is required to segregate cash or
                             other liquid assets equal to the value of the
                             securities purchased. At December 31, 1997, the
                             Kemper Government Securities Portfolio had
                             $7,140,000 of purchase commitments outstanding (8%
                             of net assets) with a corresponding amount of
                             assets segregated.
 
                             EXPENSES. Expenses arising in connection with a
                             Portfolio are allocated to that Portfolio. Other
                             Fund expenses are allocated among the Portfolios in
                             proportion to their relative net assets.
 
                             FUND SHARE VALUATION. Shares of each Portfolio of
                             the Fund are offered on a continuous basis to the
                             separate accounts of participating insurance
                             companies where permitted by law. On each day the
                             New York Stock Exchange is open for trading, each
                             Portfolio determines its net asset value per share
                             (NAV) by dividing the total value of the
                             Portfolio's investments and other assets, less
                             liabilities, by the number of Portfolio shares
                             outstanding. The NAV is determined as of the
                             earlier of 3:00 p.m. Chicago time or the close of
                             the Exchange for all Portfolios, and additionally
                             at 11:00 a.m. Chicago time for the Kemper Money
                             Market Portfolio. Because of the need to obtain
                             prices as of the close of trading on various
                             exchanges throughout the world, the calculation of
                             net asset value for the International Portfolio
                             does not take place contemporaneously with the
                             determination of prices of the Fund's foreign
                             securities.
 
                             FEDERAL INCOME TAXES. Each Portfolio has complied
                             with the special provisions of the Internal Revenue
                             Code available to investment companies and
                             therefore no federal income tax provision is
                             required. The accumulated net realized loss on
                             sales of investments for federal income tax
                             purposes at December 31, 1997 amounted to
                             approximately $19,205,000 in the Kemper High Yield
                             Portfolio, $4,613,000 in the Kemper Government
                             Securities Portfolio and $134,000 in the Kemper
                             Blue Chip Portfolio. These losses are available to
                             offset future taxable gains in the respective
                             Portfolios and, if not applied, expire during the
                             period 1998 through 2006.
 
                             DIVIDENDS TO SHAREHOLDERS. All Portfolios, except
                             the Kemper Money Market Portfolio, declare and pay
                             dividends of net investment income and net realized
                             capital gains annually, which are recorded on the
                             ex-dividend date. The Kemper Money Market Portfolio
                             declares a daily dividend equal to its net
                             investment income for that day, payable monthly.
 
                             Shareholders receive dividends in additional
                             shares.
 
                                                                              29
 
<PAGE>   30
NOTES TO FINANCIAL STATEMENTS
 
                             Dividends are determined in accordance with income
                             tax principles which may treat certain transactions
                             differently from generally accepted accounting
                             principles. These differences are primarily due to
                             differing treatments for certain transactions such
                             as foreign currency transactions, if applicable.
 
                             EQUALIZATION ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares in all
                             Portfolios except the Kemper Money Market Portfolio
                             is credited or charged to undistributed net
                             investment income so that income per share
                             available for distribution is not affected by sales
                             or redemptions of shares.

3    TRANSACTIONS WITH
     AFFILIATES              INVESTMENT MANAGER COMBINATION. Effective December
                             31, 1997, Zurich Insurance Company, the parent of
                             Zurich Kemper Investments, Inc. (ZKI), acquired a
                             majority interest in Scudder, Stevens & Clark, Inc.
                             (Scudder), another major investment manager. As a
                             result of this transaction, the operations of ZKI
                             were combined with Scudder to form a new global

                             December 31, 1997, is the same in all material
                             respects as the previous management agreement,

                             Fund's principal underwriter was changed to Kemper
                             Distributors, Inc. (KDI).

6    FINANCIAL FUTURES
     CONTRACTS               The Kemper Small Cap Value and Kemper Government
                             Securities Portfolios have entered into exchange
                             traded financial futures contracts in order to take
                             advantage of anticipated market conditions and, as
                             such, bear the risk that arises from entering into
                             these contracts.
 
                             At the time a Portfolio enters into a futures
                             contract, it is required to make a margin deposit
                             with its custodian. Subsequently, gain or loss is
                             recognized and payments are made on a daily basis
                             between the Portfolios and the broker as the market
                             value of the futures contract fluctuates. At
                             December 31, 1997, the market value of assets
                             pledged by the Portfolios to cover margin
                             requirements for open futures positions were
                             $100,000 and $212,000 for the Kemper Small Cap
                             Value and Kemper Government Securities Portfolios,
                             respectively. The Portfolios also have liquid
                             assets in their portfolios in excess of the face
                             amount of open futures contracts. At December 31,
                             1997, the Portfolios had the following futures
                             contracts open, with expirations in March, 1998:

7    FORWARD FOREIGN
     CURRENCY CONTRACTS      In order to protect itself against a decline in the
                             value of a particular foreign currency against the
                             U.S. Dollar, the Kemper Global Income Portfolio has
                             entered into forward contracts to deliver foreign
                             currency in exchange for U.S. Dollars as described
                             below. The Portfolio bears the market risk that
                             arises from changes in foreign exchange rates, and
                             accordingly, the net unrealized gain or loss
                             amounts on these contracts are reflected in the
                             accompanying financial statements. The Portfolio
                             also bears the credit risk (which is limited to the
                             unrealized gain, if any) if the counterparty fails
                             to perform under the contract. At December 31,
                             1997, the Portfolio had the following forward
                             currency contracts outstanding with settlement
                             dates in April and July, 1998:
