DEAR SHAREHOLDER:
 
If you think the first quarter of 1999 has seemed rather anticlimactic compared
to 1998, you're not alone. The year began with a quiet bang in the U.S. stock
market, with the Dow Jones Industrial Average hitting an all-time high of 9,643
points in the first week of January. While stock market volatility has
continued, it seems to be fazing investors less and less. Even global events are
being taken in stride. Europe's Economic and Monetary Union (EMU) was launched
without much notice. And when Brazil's economy recently took a turn for the
worse, Wall Street was only mildly concerned. Also contributing to today's
laid-back attitude, the impeachment trial of President Clinton has all but
fizzled into obscurity without significantly affecting the U.S. economy or
markets.
 
  Indeed, the U.S. economy looks good. The fundamentals by which we measure the
state of the economy remain strong. We continue to see solid consumer spending
growth, continued investment spending and low inflation. This suggests that
there are no internal problems for continued U.S. economic growth.
 
  Additionally, we can expect the Federal Reserve Board to keep short-term
interest rates low. On February 3, the Fed left interest rates unchanged. It is
likely that this "hands-off" approach will continue, particularly if the U.S.
economy remains in check and there is a degree of uncertainty in the
international arena.
 
  The U.S. budget surplus for 1998 came in at $60 billion, with another budget
surplus of between $80 billion and $100 billion expected for fiscal 1999. Growth
in the nation's gross domestic product (GDP), which represents the total value
of all goods and services produced within the U.S. economy, has remained steady.
GDP, driven by consumer spending, is expected to grow at an annualized rate of
approximately 3 percent in 1999. We also anticipate modest capital spending
growth and modest inventory growth.

  The consumer price index (CPI) remains in the vicinity of 2 percent. However,
energy prices, which were down 6 to 7 percent last year and helped keep the CPI
down, are unlikely to remain so low this year.
 
  Employment growth has slowed to 2 percent, combined with real wage growth of
between 2 percent and 2.5 percent. But real income growth is between 4 percent
and 5 percent. In addition, gains in household net worth, which tends to fuel
consumer spending, are also on the rise. Banks appear to be only a little less
willing to lend in 1999, so the threat of a general credit crunch is minimal.
 
  On a less positive note, corporate profits have slowed in 1999, growing at a
rate of 1 percent to 3 percent on a year-over-year basis. As a result, we may
see a slowdown in capital spending this year. The current U.S. account deficit
is rising, which suggests the U.S. economy is increasingly dependent on foreign
capital inflows to finance its economic activity. This is acceptable as long as
foreign money continues to flow in. But if foreign investors, particularly the
Japanese, no longer wish to invest in the United States, we can expect problems
for interest rates and exchange rates, as well as increased uncertainty and
market volatility.
 
  At this point, investors may be comforted by the fact that the U.S. markets
and economy have withstood the test of a tumultuous 1998. While certain
countries, such as Malaysia, Indonesia, Brazil and Russia, are still suffering
from economic crises, others, including the Philippines, South Korea, Thailand
and China, appear to have survived. As long as the Fed and the Group of Eight
leading industrial nations (G8) are committed to avoiding recession on national
and global levels, respectively, investors have a good chance of experiencing a
more stable economic environment.
 
  At home, there has been somewhat of a slowdown in manufacturing, as reduced
U.S. exports reflect foreign economic turmoil. But the global impact of the
Asian crisis still has not hit the U.S. as hard as some analysts expected.
Indeed, Asian turmoil has not affected U.S. export volumes as much as it has
lowered import prices and helped reduce global interest rates.
 
  Ultimately, Europe's recently inaugurated EMU is likely to bring more
flexibility and growth potential for the region. European equities may be the
beneficiaries of increased spending, as governments seek to ease fiscal and

monetary policy, foster growth and reduce unemployment. It's going to be
interesting to watch as the monetary union continues to evolve. One lesson for
investors -- particularly those with international holdings -- is to diversify.
With the democratization of the world, the globalization of trade and more free
market economies at our fingertips, international markets are becoming more and
more attractive. But if you subscribe to the concept of international
investment, be cautious -- don't put all of your investment eggs in one basket.
 
  Other key elements to watch in 1999: the race for the next presidency and
preparedness for the year 2000. And remember, while it is nearly impossible to
predict the next big crisis, there always appears to be one just around the
bend.
 
  Thank you for choosing to invest in the Investors Fund Series. We appreciate
the opportunity to serve your investment needs.

MANAGEMENT SUMMARY

 
KEMPER MONEY MARKET PORTFOLIO
- ------------------------------------
 
  In general, the Money Market Portfolio maintained a defensive, short average
maturity strategy throughout much of 1998. Early in the year, the direction of
interest rates was uncertain, and the yield curve offered no income reward for
lengthening the portfolio.
  For a good portion of 1998, events unfolded as we expected. We maintained a
neutral average maturity policy, which provided us with the flexibility to react
quickly to developing market opportunities.
  That flexibility proved to be valuable in light of August's market volatility
and the Federal Reserve's decision to ease rates twice in October. The Money
Market Portfolio was able to provide the stability investors seek in rocky
times.
  Following these events, we made the decision to lengthen the portfolio's
duration, given that the economy appears on solid footing and the Federal
Reserve appears unlikely to make any rate changes.
  Going forward, we will continue to emphasize high-quality credits, which
allows us to help provide the stability and liquidity our investors expect from
the Money Market Portfolio.

KEMPER TOTAL RETURN PORTFOLIO
- ------------------------------------
 
  While there were periods of brisk market activity in 1998, volatility was ever
present. Investors grappled to make sense of the potential impact of events both
at home and abroad. Our conservative approach to growth served the portfolio
well during the market downturns while also providing good opportunities to
participate in the upswings. And during the market's turmoil, our fixed income
holdings performed as we anticipated, providing a degree of stability.
  Our stock selection discipline also helped returns, with many of our large
holdings turning in nice gains. The portfolio enjoyed good performance from
telecommunication stocks, such as MCI and Ameritech. Quality technology
companies, including Cisco Systems, IBM and Sun Microsystems, also bolstered
gains. Health care was another area where our strategy paid off, with Schering-
Plough and Abbott Laboratories among the ranks of solid performers.
  While our bond holdings served as stabilizing factors during the equity market
turmoil, the tradeoff was that we did not participate fully in the equity market
rebound late in 1998. As a balanced portfolio, however, that is a tradeoff with
which we feel comfortable. We understand that our investors put a premium on
steady, consistent performance.
  Overall, we believe that a disciplined, diversified approach to investing
still offers strong potential for long-term investors. As we enter the new year,
we encourage investors to hold the course.

KEMPER HIGH YIELD PORTFOLIO
- ------------------------------------
 
  1998 proved itself a peculiar and historic year for the high-yield market. The
market experienced one of its worst months ever--and then one of its best just
three months later.
  The low point occurred in August 1998, when it became clear the Asian
financial problems were not getting any better. Concurrently, financial problems
in Russia put pressure on the dealer and banking communities in the United
States, creating a serious liquidity problem in the market.
  In retrospect, we see the August downturn as a technical reaction to events
external to the high-yield market. The fundamentals of the high-yield market are
healthy, and the Federal Reserve's willingness to ease interest rates has gone a
long way toward curing the liquidity crisis and getting the market back on
track.
  The downturn did offer some benefits. The high-yield market was driven down to
the point where we saw good values in many of the companies on which we do
extensive research. As a result, we carried a very low cash position in the
Kemper High Yield Portfolio. We tried to stay fully invested in order to
participate fully in the turnaround, which began almost immediately after
August's correction, and, as measured by the DLJ High Yield Index, hit its peak
with a 5.62% rise in the market in November--the highest single-month increase
since March 1991.
  Liquidity in the market continues to improve, and in 1999 we should have more
and more opportunities to take advantage of good values in the market. Whether
an investor is total-return-oriented or looking for income, high-yield investing
might make sense.

MANAGEMENT SUMMARY


KEMPER GROWTH PORTFOLIO
- ------------------------------------
 
  During the past year, uncertainty about the global financial markets created
an extreme, two-tiered market of historic proportions -- a market in which the
highest-quality, most predictable companies have done very well, and companies
with any exposure to Asia and any possibility of weakness have languished. The
performance gap between the few companies on the first tier and the rest on the
second tier stood at historic levels for most of the year.
  For growth-at-a-reasonable-price investors, 1998's market was a difficult one.
Nonetheless, we have found many opportunities that we expect to perform well
once the market moves on to a more reasonable stage with a broader-based market
advance.
  In the technology sector, for example, we found very good opportunities among
semiconductor manufacturers, personal computer makers and software service
companies. Specifically, we initiated positions in Xerox and Dell, both of which
were reasonably priced and high quality. As that sector grew increasingly strong
during the year, however, we sold some of our holdings and reallocated the
assets toward specialty retailers and heath care stocks. The portfolio employed
a similar strategy -- selling into strength -- to take profits in some of its
financial services holdings.
  Despite the volatility of the past year, we believe the portfolio's
growth-at-a-reasonable-price discipline helped the portfolio reap rewards from
many of its mature holdings and identify many attractive new holdings. As we
move forward and markets grow less volatile, we expect the portfolio to be well
positioned for long-term performance potential.

KEMPER GOVERNMENT SECURITIES PORTFOLIO
- ------------------------------------
 
  Without a doubt, the most significant impact on the portfolio this year was
felt as a result of the instability in foreign bond and stock markets -- first
from developments in Asia, then Russia and finally in Latin America. The
problems abroad led to strong performance by U.S. Government bonds, long
considered the safest investment in the world.
  The sound performance of the portfolio in 1998 was due in part to our
adjustment of duration in response to interest rates, as well as our adjustment
of the allocation between Treasuries- and mortgage-backed securities. We did
both well this year.
  Most recently, we have boosted our mortgage allocation to a neutral weighting,
because we do not believe long rates can go much lower in the near term, nor do
we believe they will trend significantly higher. So we have adopted what might
be considered a "normal" stance regarding our duration and allocation.
  Going forward, we expect investors' focus to turn closer to home. Static from
foreign markets has, to this point, muddied a very favorable environment for
government bonds. Inflation remains low and economic growth appears to be solid
and sustainable. That would lead us to expect a slow-growth, low-inflation
environment that would be beneficial for bonds. We fully expect some additional
volatility in the markets as a few big hedge funds unwind some overzealous
currency and fixed-income positions. But overall, we believe the climate for
fixed-income investors is quite favorable.
 
Richard L. Vandenberg
Lead Portfolio Manager
 
KEMPER INTERNATIONAL PORTFOLIO
- ------------------------------------
 
  Although early in the year the portfolio posted some solid numbers, fueled in
part by the strength in Europe, worldwide markets took some dramatic turns
toward the end of 1998 that dampened our performance.
  Nearly all global markets fell sharply in August, but an October rebound
allowed recent market dogs to have their day. Latin American and Southeast Asian
markets surged; Hong Kong, for example, was up 33% in dollar terms for the
month. We missed the short-term gains offered by this bounce because of our
light exposure to these markets compared with the index. We maintain small
positions in these markets in part because the portfolio is generally never
highly exposed to emerging markets as a matter of policy, and because we saw
some of these areas as fundamentally weak.
  In 1998, as in other years, we focused on the fundamentals of valuation and
growth to try to achieve a strong, long-term track record. We do not change the
way we run the fund to suit short-term circumstances. When markets fluctuate as
they did in 1998, there are going to be times in which our management style does
not look appealing. But eventually, markets have tended to stabilize and widen
their scope to focus on the long-term fundamentals.
  We firmly believe that the investor who is comfortable riding through some
bumpy market patches may be rewarded as huge economic regions like Europe and
Japan hit their full strides.

MANAGEMENT SUMMARY

 
KEMPER SMALL CAP GROWTH PORTFOLIO
- ------------------------------------
 
  1998 was yet another positive year for the Small Cap Growth Portfolio, its
fourth in a row. In spite of heavy volatility at points during the year and an
inhospitable market climate for small caps, we continued to find many good
values within the portfolio's investment universe. That means that the portfolio
is not only well positioned for the near term, but we believe its future is
bright as well.
  Over the past several months, the portfolio has emphasized stocks in several
sectors, including retail, broadcasting and education. Although the market has
not favored small caps in general, some holdings in these groups have performed
well in the current economic environment, which is distinguished by low interest
rates and moderate growth.
  We believe that equities in the technology sector will continue to be an
important part of the portfolio's long-term focus. In particular, select
software and semiconductor equipment stocks are attractive at the current time.
  Although it is difficult to predict when small cap stocks may begin to
outperform their large cap counterparts, we remain bullish on the portfolio's
prospects. We will maintain our disciplined investment focus and continue to
search for attractive investment opportunities in the current environment.
 
David H. Burshtan
Lead Portfolio Manager
 
KEMPER INVESTMENT GRADE BOND PORTFOLIO
- ------------------------------------
 
  The Investment Grade Bond Portfolio came through the year unscathed by a
choppy market environment. The portfolio normally has a higher allocation of
corporate bonds in its mix than many of its peers, a fact that could have
spelled trouble in a year that favored only Treasury securities. But we
maintained a higher-quality portfolio than many similar portfolios and we held
fewer corporates than we usually do, and during the flight to quality in 1998,
that higher quality worked to the portfolio's advantage.
  We made several portfolio adjustments during the year, among them increasing
the allocation to Treasuries and reducing our allocation to corporate bonds.
There were several points during the year when what happened overseas
dramatically affected the corporate market. All through the spring, we lightened
up on corporates, and that worked in our favor during a very difficult August
and October in the corporate market.
  We also lengthened the portfolio's duration for most of the year to take
advantage of the flight to quality in the market and the deflationary tone set
by events overseas. By increasing the portfolio's duration, we increased its
sensitivity to a drop in interest rates, which improved the portfolio's total
return as rates declined.
  Going forward, we see the economy slowing a bit, but we do not see anything
like a recession on the horizon. The money that poured into Treasuries during
the year will likely be redeployed into corporate or mortgage bonds, which
should improve those markets. Consequently, we intend to pursue a strategy of
increasing mortgages in the portfolio at the appropriate time.
 
Robert Cessine
Lead Portfolio Manager
 
KEMPER CONTRARIAN VALUE PORTFOLIO
- ------------------------------------
 
  For a good portion of the year, the U.S. stock market continued in a "Nifty
Fifty" mode, meaning that a handful of the largest capitalization stocks
outperformed a vast majority of the market. While the dominance of these issues
was challenged somewhat by the market's volatility in 1998, stocks with smaller
capitalizations still did not enjoy an extended period of prominence.
  The Contrarian Value Portfolio, therefore, continues to wait out the bias
toward these mega-cap growth stocks. But despite the fact the market has
primarily favored stocks in which the Contrarian Value Portfolio won't invest,
we've been pleased with our performance to date and continue to add stocks that
we believe can bring long-term value to the portfolio -- stocks that appear to
have limited downside risk and solid return potential.
  Among these are issues in which the portfolio already maintained positions,
including Amoco, General Electric, Hewlett-Packard and Kimberly-Clark. We
believe that the combination of attractive valuations and strong earnings growth
is still fairly powerful in this group. Other holdings that performed well
during the course of the year were Philip Morris and AMP.
  We also continued to maintain a weighting in basic materials stocks, such as
diversified forest products, paper, chemicals and steel, and the energy group as
well.
  We look forward to the fact that, sooner or later, the market's "Nifty Fifty"
orientation will shift, which may create even more opportunities for the
Contrarian Value Portfolio. In the meantime, market volatility and other
conditions continue to afford us opportunities to find good values among quality
companies. We will continue to capitalize on these openings when they occur and
keep the portfolio well positioned for the long term.

MANAGEMENT SUMMARY

KEMPER SMALL CAP VALUE PORTFOLIO
- ------------------------------------
 
  In 1998, both small cap and value stocks bore the brunt of the recent market
volatility as many investors redeployed their assets toward U.S. Treasuries and
the bluest of the blue chip stocks. For the Small Cap Value Portfolio, that
"double whammy" translated into a generally difficult year.
  In addition to the decline in small caps and value stocks, we were also
hindered by some large positions in sectors that underperformed our expectations
- -- energy and specialty finance. Energy stocks suffered in 1998 as
warmer-than-average temperatures continued during most of the year and crude oil
prices declined. The financial services sector suffered with the Russian debt
crisis and fears of a credit crunch at home.
  Although we did not see many positive results in 1998, we did use the down
market as an opportunity to add value to the portfolio. We added dozens of new
names, such as Inter-tel, Inc., a digital communication firm; Southdown, Inc., a
manufacturer of concrete products; and Pacific Sun Wear, an apparel retailer.
  Overall, we believe we have a diversified, undervalued portfolio of solid
companies, which helps position us well for the future. Regardless of market
conditions, we will continue to focus on a bottom-up approach to stock
selection, identifying companies with considerable value relative to the market.
When small caps gain back their strength, we expect that strategy to serve us
well.

KEMPER VALUE+GROWTH PORTFOLIO
- ------------------------------------
 
  Overall, the market posted brisk returns during 1998, but investors continued
to be buffeted by periods of ups and downs. Worries about Asia and Russia and
uncertainty about Federal Reserve policy during the summer all contributed to
choppy waters.
  Domestic large company growth stocks led the way during most of the year.
Although that narrow market limited near-term performance for many stocks, it
opened up many attractive buying opportunities for those with a long-term focus.
  Given the markets' unpredictability, we steered away from sector-based
forecasting and instead focused on individual stock selection. Early in the
year, the majority of the portfolio's assets were allocated toward growth
stocks, although as the year progressed and we became more concerned about high
valuations, we bolstered our value allocation. By September, the portfolio's
allocation was equally weighted between growth and value issues. Although this
allocation was generally a positive move, it did limit our participation in a
late-year growth stock rally.
  Specifically, the portfolio enjoyed success during the year with technology
stocks, including Sun Microsystems, although the sector as a whole proved to be
a mixed bag. Some of our financial services holdings, including FHLMC, Citigroup
and FNMA, also performed well.
  We expect volatility to continue, primarily because we have not seen
sufficient indications that the turmoil in Asia, Russia and South America is
anywhere near finished. Nevertheless, we believe in the long-term potential of
domestic equity investing and in the power of thorough, disciplined stock
selection.

KEMPER HORIZON 20+, HORIZON 10+ AND HORIZON 5 PORTFOLIOS
- ------------------------------------
 
  It goes without saying that 1998 was a volatile year for investors. Although
markets did seem to calm themselves after October 1997, periodic bursts of
market unease led up to a rather large correction in August 1998. Domestic
equity markets rebounded quickly, however, before settling into the tides of
periodic volatility that characterized the last few months of the year.
  The Horizon Portfolios have been able to manage market volatility due to
diversification. We do believe that over the long-term, this diversification
across multiple asset classes, including value stocks, growth stocks,
international and small company stocks, will lead to increased risk-adjusted
return potential.
  With the portfolios this year, our bond stake provided protection against
market turbulence. Our fixed-income allocation was quality focused and held an
average credit rating of AAA. We have invested in U.S. Treasuries and mortgage-
backed securities, and although the fund can invest in high-yield bonds, we
opted to eschew that area for most of the year.
  Within the equity portions of our portfolio, we found some success with
selected technology issues, including Sun Microsystems, and financial services
stocks, including Citigroup. Most of the portfolios' equity successes, however,
were among larger cap stocks, and our smaller cap holdings tended to place a
drag on our performance.
  Going forward, we will continue to adhere to our disciplined, quantitative
focus. We believe that, over the long term, keeping clear-sighted and
cool-headed is the most sensible course. We remain confident about the longer-
term potential of a diversified approach that includes a broad variety of
assets.

MANAGEMENT SUMMARY

KEMPER BLUE CHIP PORTFOLIO
- ------------------------------------
 
  Investors can take comfort from the fact that both the U.S. markets and the
Blue Chip Portfolio held up well during a tumultuous year in 1998. Despite
particularly volatile conditions at certain points during the year, we
maintained a focus on our growth-at-a-reasonable-price discipline, which helped
us identify several attractive stocks over the period and remain focused on
long-term results.
  That wasn't easy, however. Our blue-chip hunting grounds were thinned out by a
flight to higher-quality stocks and the resulting higher stock prices. Because
of these steep prices, we were precluded from owning several market favorites
like Microsoft and Lucent. Nonetheless, we were able to find a handful of worthy
issues.
  Thanks to market performance between August and October, we were allowed entry
points into higher-quality stocks, such as Wal-Mart, Home Depot and Pfizer, at
fairly reasonable prices.
  One example of a stock that met our criteria was Motorola. The stock is
attractively priced, and our research indicates that it benefits from several
growth catalysts that may help push its price higher.
  Raytheon also possesses many of the attributes we look for. It is a defense
and aerospace firm with a well-thought-out, rational expansion plan. It is also
a company with a great deal of exciting growth potential. In addition,
telecommunications stocks like AT&T and US West have appealing valuations and a
combination of growth and income potential that we like.
  Going forward, we expect volatility to continue in some form. In a global
economy, it is prudent to expect that uncertainty will always be present. What
really counts is how we respond to that uncertainty. The bottom line is that we
believe a thoughtful, long-term investment discipline has the potential to
translate some volatility into opportunity for our investors.

KEMPER GLOBAL INCOME PORTFOLIO
- ------------------------------------
 
  Throughout most of 1998, the bond markets of the developed nations continued
to benefit from the deflationary impact of the Asian crisis. There was a
continued flight to quality from emerging bond and equity markets.
  At the start of 1998, the Global Income Portfolio was overweight in Australia,
New Zealand and U.K. markets and underweight in U.S., Japan and peripheral
Europe markets. However, due to lower expected returns caused by higher
inflation, we removed our Australia position and reduced our U.K. position.
  We increased our position in Canada early in the year because of
higher-than-expected returns, but decreased it later due to a weakening of the
currency. By contrast, European debt became more attractive during the year due
to a series of interest rate cuts. Japanese bonds continued to underperform, and
in October we cut in half our exposure to the market. To date, we still see few
immediate solutions to the Asian crisis being offered.
  Despite concerns about several large economic powers, the outlook for many
bond markets around the globe remains strong. Bond yields have declined in
tandem with inflationary expectations in many countries, and we believe that
many markets continue to be fairly valued in general. Close on the heels of the
Federal Reserve's decision to ease rates twice, and because economic growth is
reasonable, the market does not expect the Fed to tighten its policy.

KEMPER-DREMAN HIGH RETURN EQUITY PORTFOLIO
- ------------------------------------
 
  1998 presented investors with a strange market. Stocks that were already
overvalued skyrocketed to unbelievable heights, while fundamentally solid
companies with reasonable price-to-earnings multiples languished. The primary
beneficiaries of this narrow market were the largest growth-style stocks. For
value investors, therefore, it was a difficult period.
  We continued to look for financially sound companies with low
price-to-earnings, price-to-book, price-to-cash-flow and price-to-dividend
ratios. As contrarians, we are always loath to pay a premium for any stock, and
this year was no different.
  Financial services stocks made up the largest portion of the portfolio last
year, and we focused in particular on regional banks that had no foreign
exposure. As a result, the portfolio's financial services holdings withstood the
downturn in August much better than the sector as a whole. In September, we took
some positions in money-center banks and added to others at discounted prices.
The prices of these stocks rose dramatically through September and October.
  On the downside, our holdings in oil and tobacco suffered at times during the
year, but we believe they have good long-term prospects.
  We expect volatility to continue in 1999, so we will continue to manage the
portfolio conservatively. However, if volatility knocks down areas we like, we
will become more aggressive and take advantage of those opportunities.

KEMPER-DREMAN FINANCIAL SERVICES PORTFOLIO
- ------------------------------------
 
  Launched in March 1998, the portfolio enjoyed a very eventful inaugural year.
At inception, the financial stocks had risen steeply and it was difficult to
find stocks that were undervalued. Then financial services stocks began to
underperform for the first time in a decade. As the sector began to stumble in
the summer, we moved in and added several quality stocks that were trading at a
discount. Since then, the market has started to climb and these holdings have
been positive for the portfolio.
  Primarily, we have structured a conservative portfolio that could really take
off when the tide shifts and value stocks come back into favor. But we are also
opportunistic. If something lags the market, like the big money-center banks did
this past summer, we invest quickly to add value. We are always looking for
those breaks in the market.
  Regional banks like First Union and KeyCorp also provided value opportunities
this year, and we focused much of our investment there. The upside with the
regional banks is that they don't have any foreign exposure like larger
institutions, and many of them are strong takeover candidates.
  We fully expect that the growth in financial services will continue at a
healthy rate. It is a sector with a great deal of potential. Banks,
specifically, have a good deal more growth ahead. We've been pleased with our
performance and hope that it will improve with time. Our performance is a
reflection of our conservative, contrarian investment approach, and we believe
that approach may yield long-term benefits for our investors.

KEMPER GLOBAL BLUE CHIP PORTFOLIO
- ------------------------------------
 
  The risks that we perceive in both the global economy and individual financial
markets have led us to remain flexible for most of 1998. As a result, our
investment action has concentrated on additions to the "secure streams of
income" theme -- that is, investments that we believe will produce reliable
streams of income in the future as supply of similar investments has diminished.
These investments include National Grid Group and Peco Energy. We are also
concentrating on sales of some of the fully valued holdings in our European-
oriented themes and the development of our new theme, "The Empowered Consumer."
  "The Empowered Consumer" is focused on the rollout of the benefits of
technology to households through price arbitrage and more efficient ordering and
delivery systems. Examples from this theme include Comcast Corp, Motorola and
Tele-Comm Liberty Media.
  Some of the fundamental drivers underlying our investment themes are changing.
While restructuring still has considerable potential outside the U.S.,
deflationary risks are becoming more evident. The furious pace of the recent
merger and acquisition activity is inspired by cost cutting and the elimination
of capacity, and, as a defense against deflation, we believe this activity will
not yield the same benefits as earlier restructuring. Driving this deflation, in
part, are new and not-so-new technologies. Techno-euphoria is, however, complex,
and investment opportunities in this area that are both sustainable and
affordable must be selected with care.
  In our search for new themes, we are seeking to understand the wider
implications of the latticework of structural imbalances that today characterize
the global economy. We believe that financial markets are still exuberant, still
irrational. In the meantime, the portfolio remains positioned for change.

KEMPER INTERNATIONAL GROWTH AND INCOME PORTFOLIO
- ------------------------------------
 
  It has been a historic year in the international markets. In the year since
the portfolio's inception, on January 1, 1998, investors have seen the
formalization of the European Monetary Union, significant economic uncertainty
in Japan and Russia and considerable volatility in almost every market.
  Despite these events, the focus of the portfolio remained on identifying
relative yield -- the universe of stocks offered incrementally higher yields
than their broader markets. We believe a relative yield approach best identifies
stocks that are undervalued and helps the portfolio stay a steady course.
  Within the framework of that approach, we sought out regions that we believed
would show strength during the year as well as sectors that were best positioned
to benefit from some of the positive changes occurring in the region, including
Europe's consumer stocks and telecommunications. We reduced our holdings in
European banks, largely because financial stocks floundered as a result of
global currency concerns. Overall, the long-term picture for Europe and its
markets continues to be very positive.
  Japan remained a region to avoid except for a few, highly selective buying
opportunities, and our caution was rewarded during periods of volatility during
the year.
  Going forward, we expect to see the European market continue to be strong,
while recovery in Japan will be steady but slow. Russia will continue to be a
source of trouble and we will work to reduce the risk profile of the portfolio
by staying away from financial stocks with exposure to the Russian economy.

(1)AVERAGE ANNUAL TOTAL RETURN AND TOTAL RETURN MEASURE NET INVESTMENT INCOME
   AND CAPITAL GAIN OR LOSS FROM PORTFOLIO INVESTMENT OVER THE PERIODS
   SPECIFIED, ASSUMING REINVESTMENT OF ALL DIVIDENDS. AVERAGE ANNUAL TOTAL
   RETURN REFLECTS ANNUALIZED CHANGE WHILE TOTAL RETURN REFLECTS AGGREGATE
   CHANGE. PERFORMANCE IS NET OF THE PORTFOLIO'S MANAGEMENT FEE AND OTHER
   OPERATION EXPENSES BUT DOES NOT INCLUDE ANY DEDUCTION AT THE SEPARATE ACCOUNT
   OR CONTRACT LEVEL FOR ANY INSURANCE OR SURRENDER CHARGES THAT MAY BE INCURRED
   UNDER A CONTRACT. PLEASE SEE PROSPECTUS FOR MORE DETAILS.
 
   PAST PERFORMANCE IS NOT A GUARANTEE OF FUTURE PERFORMANCE. RETURNS AND
   PRINCIPAL VALUES FLUCTUATE SO THAT ACCUMULATION UNITS, WHEN REDEEMED, MAY BE
   WORTH MORE OR LESS THAN ORIGINAL COST.

(1) AVERAGE ANNUAL TOTAL RETURN AND TOTAL RETURN MEASURE NET INVESTMENT INCOME
    AND CAPITAL GAIN OR LOSS FROM PORTFOLIO INVESTMENT OVER THE PERIODS
    SPECIFIED, ASSUMING REINVESTMENT OF ALL DIVIDENDS. AVERAGE ANNUAL TOTAL
    RETURN REFLECTS ANNUALIZED CHANGE WHILE TOTAL RETURN REFLECTS AGGREGATE
    CHANGE. PERFORMANCE IS NET OF THE PORTFOLIO'S MANAGEMENT FEE AND OTHER
    OPERATION EXPENSES BUT DOES NOT INCLUDE ANY DEDUCTION AT THE SEPARATE
    ACCOUNT OR CONTRACT LEVEL FOR ANY INSURANCE OR SURRENDER CHARGES THAT MAY
    BE INCURRED UNDER A CONTRACT. PLEASE SEE PROSPECTUS FOR MORE DETAILS.
 
    PAST PERFORMANCE IS NOT A GUARANTEE OF FUTURE PERFORMANCE. RETURNS AND
    PRINCIPAL VALUES FLUCTUATE SO THAT ACCUMULATION UNITS, WHEN REDEEMED, MAY BE
    WORTH MORE OR LESS THAN ORIGINAL COST.

(1) AVERAGE ANNUAL TOTAL RETURN AND TOTAL RETURN MEASURE NET INVESTMENT INCOME
    AND CAPITAL GAIN OR LOSS FROM PORTFOLIO INVESTMENT OVER THE PERIODS
    SPECIFIED, ASSUMING REINVESTMENT OF ALL DIVIDENDS. AVERAGE ANNUAL TOTAL
    RETURN REFLECTS ANNUALIZED CHANGE WHILE TOTAL RETURN REFLECTS AGGREGATE
    CHANGE. PERFORMANCE IS NET OF THE PORTFOLIO'S MANAGEMENT FEE AND OTHER
    OPERATION EXPENSES BUT DOES NOT INCLUDE ANY DEDUCTION AT THE SEPARATE
    ACCOUNT OR CONTRACT LEVEL FOR ANY INSURANCE OR SURRENDER CHARGES THAT MAY BE
    INCURRED UNDER A CONTRACT. PLEASE SEE PROSPECTUS FOR MORE DETAILS.
 
    PAST PERFORMANCE IS NOT A GUARANTEE OF FUTURE PERFORMANCE. RETURNS AND
    PRINCIPAL VALUES FLUCTUATE SO THAT ACCUMULATION UNITS, WHEN REDEEMED, MAY BE
    WORTH MORE OR LESS THAN ORIGINAL COST.

  We conducted our audits in accordance with generally accepted auditing

test basis, evidence supporting the amounts and disclosures in the financial

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 their operations, the changes in their net assets and the financial

1    DESCRIPTION OF THE                                                        
     FUND                    Investors Fund Series (the fund) is an open-end,  
                             management investment company organized as a     
                             business trust under the laws of Massachusetts. The
                             fund offers twenty portfolios.                    
                                                                               
- --------------------------------------------------------------------------------
2    SIGNIFICANT
     ACCOUNTING POLICIES     SECURITY VALUATION. Investments are stated at
                             value. The securities of the portfolios which are
                             traded on U.S. or foreign stock exchanges are
                             valued at the most recent sale price reported on
                             the exchange on which the security is traded most
                             extensively. If no sale occurred, the security is
                             then valued at the calculated mean between the most
                             recent bid and asked quotations. If there are no
                             such bid and asked quotations, the most recent bid
                             quotation is used. Securities quoted on the Nasdaq
                             Stock Market (Nasdaq), for which there have been
                             sales, are valued at the most recent sale price
                             reported. If there are no such sales, the value is
                             the most recent bid quotation. Securities which are
                             not quoted on Nasdaq but are traded in another
                             over-the-counter market are valued at the most
                             recent sale price on such market. If no sale
                             occurred, the security is then valued at the
                             calculated mean between the most recent bid and
                             asked quotations. If there are no such bid and
                             asked quotations, the most recent bid quotation is
                             used. Forward foreign currency exchange contracts
                             are valued at the prevailing forward exchange rates
                             of the underlying currencies on that day. Futures
                             contracts are valued at the most recent settlement
                             price.
 
                             Portfolio debt securities are valued by pricing
                             agents approved by the officers of the fund, which
                             quotations reflect broker/dealer-supplied
                             valuations and electronic data processing
                             techniques. If the pricing agents are unable to
                             provide such quotations, the most recent bid
                             quotation supplied by a bona fide market maker
                             shall be used.
 
                             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-based values, 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.
 
                             All other securities are valued at their fair
                             market value as determined in good faith by the
                             Valuation Committee of the Board of Trustees.
 
                             FOREIGN CURRENCY TRANSLATION. The books and records
                             of the fund are maintained in U.S. dollars.
                             Investment securities and other assets and
                             liabilities denominated in a foreign currency are
                             translated into U.S. dollars at the prevailing
                             rates of exchange. Purchases and sales of
                             investment securities, income and expenses are
                             translated into U.S. dollars at the prevailing
                             exchange rates on the respective dates of the
                             transactions. The portfolios include that portion
                             of the results of operations resulting from changes
                             in foreign exchange rates with net realized and
                             unrealized gain (loss) on investments, as
                             appropriate.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date. 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. 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, 1998, the Kemper
                             Government Securities Portfolio had $2,018,000 of
                             purchase commitments outstanding (2% 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 close
                             of regular trading on the Exchange for all
                             portfolios and at 11:00 a.m. (Central 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 portfolios
                             holding foreign securities does not take place
                             contemporaneously with the determination of the
                             foreign securities' prices.
 
                             FEDERAL INCOME TAXES. Each portfolio's policy is to
                             comply with the requirements of the Internal
                             Revenue Code, as amended, which are applicable to
                             regulated investment companies, and to distribute
                             all of its taxable income to its shareholders.
                             Accordingly, each portfolio paid no federal income
                             taxes and no federal income tax provision was
                             required.
 
                             At December 31, 1998, Kemper High Yield, Kemper
                             Growth, Kemper Government Securities, Kemper Small
                             Cap Growth, Kemper Small Cap Value, Kemper Blue
                             Chip, Kemper Global Blue Chip, and Kemper
                             International Growth and Income Portfolios, had a
                             tax basis net capital loss carryforward of
                             approximately $16,910,000, $4,544,000, $3,167,000,
                             $1,588,000, $1,867,000, $3,062,000, $34,000 and
                             $72,000, respectively, which may be applied against
                             any realized net taxable gains of each succeeding
                             year until fully utilized or it will expire during
                             the period 1999 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.
 
                             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. Prior to January 1, 1998, the
                             portfolios (except the Kemper Money Market,
                             Kemper-Dreman High Return Equity, Kemper-Dreman
                             Financial Services, Kemper Global Blue Chip and
                             Kemper International Growth and Income Portfolios)
                             used equalization accounting to keep a continuing
                             shareholder's per share interest in undistributed
                             net investment income unaffected by shareholder
                             activity. This was accomplished by allocating a
                             portion of the proceeds from sales and the cost of
                             redemptions of fund shares to undistributed
 
                                                                              31

                             net investment income. As of January 1, 1998, the
                             portfolios discontinued using equalization. This
                             change has no effect on the portfolios' net assets,
                             net asset value per share or distributions to
                             shareholders. Discontinuing the use of equalization
                             accounting will result in simpler financial
                             statements. The cumulative effect of the
                             discontinuance of equalization accounting was to
                             increase (decrease) paid-in capital and (increase)
                             decrease undistributed net investment income

                             Dreman Value Management, L.L.C. serves as
                             sub-adviser with respect to the investment and
                             reinvestment of assets in the Kemper-Dreman High
                             Return Equity and Kemper-Dreman Financial Services
                             Portfolios, and is paid by Scudder Kemper for its
                             services.
 
                             ZURICH/B.A.T MERGER. On September 7, 1998, Zurich
                             Insurance Company (Zurich), majority owner of
                             Scudder Kemper, entered into an agreement with
                             B.A.T Industries p.l.c. (B.A.T) pursuant to which
                             the financial services businesses of B.A.T were
                             combined with Zurich's businesses to form a new
                             global insurance and financial services company
                             known as Zurich Financial Services. Upon
                             consummation of the transaction, each portfolio's
                             investment management agreement with Scudder Kemper
                             was deemed to have been assigned and, therefore,
                             terminated. The Board of Trustees of the fund has
                             approved new investment management agreements with
                             Scudder Kemper, which are substantially identical
                             to the former investment management agreements,
                             except for the dates of execution and termination.
                             Shareholders approved the new investment management
                             agreements through a proxy solicitation that
                             concluded in mid-December.
 
                             FUND ACCOUNTING AGENT. Scudder Fund Accounting
                             Corporation (SFAC), is responsible for determining
                             the daily net asset value per share and maintaining
                             the portfolio and general accounting records of
                             each portfolio. SFAC receives no fee for its
                             services to each portfolio other than Kemper-Dreman
                             High Return Equity, Kemper-Dreman Financial
                             Services, Kemper Global Blue Chip and Kemper
                             International Growth and Income Portfolios.
                             However, the portfolios incurred no accounting fees
                             for the period ended December 31, 1998, after a fee
                             waiver by Scudder Kemper.
 
                             OFFICERS AND TRUSTEES. Certain officers or trustees
                             of the fund are also officers or directors of
                             Scudder Kemper. During the year ended December 31,
                             1998, the fund made no direct payments to its
                             officers and incurred trustees' fees of $292,000 to
                             independent trustees.
 
                                                                              33

6    FINANCIAL FUTURES
     CONTRACTS               The Kemper-Dreman High Return Equity 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, 1998, the market value of assets
                             pledged by the portfolios to cover margin
                             requirements for open futures positions was
                             $105,000 and $126,000 for the Kemper-Dreman High
                             Return Equity and Kemper Government Securities
                             Portfolios, respectively. The portfolios also held
                             liquid securities in excess of the face amount of
                             the open futures contracts. At December 31, 1998,
                             the portfolios had the following futures contracts
                             open, which expire in March, 1999:

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,
                             1998, the portfolio had the following forward
                             foreign currency contracts outstanding with
                             settlement dates in February and March 1999.

(a) Repurchase agreements are fully collateralized by U.S. Treasury or
    Government agency securities. The collateral is monitored daily by the

    repurchase agreement.
 
The portfolio is a non-diversified investment company and may invest a
relatively high percentage of its assets in the obligations of a limited number
of issuers.
 
Based on the cost of investments of $4,836,000 for federal income tax purposes
at December 31, 1998, the gross unrealized appreciation was $108,000, the gross
unrealized depreciation was $9,000 and the net unrealized appreciation on

    contracts in order to take advantage of anticipated market conditions and
