DEAR SHAREHOLDERS,
 
  It's been a bumpy ride for many investors in the third quarter of 1998, with
concern over corporate profits generating considerable market volatility. On
August 4, the Dow Jones Industrial Average suffered its largest single-day point
drop for the year. While this was the Dow's third largest point decline in
history, it didn't even make the top 100 in terms of percentage losses. In any
event, stock market tensions spilled over into the bond markets, fueling the
debate about whether we would finally see the end of our long-running bull
market -- or even plummet into a recession.
  But investors who are riding out the stock market's abrupt short-term
adjustments should find comfort in the fact that economic fundamentals continue
to favor financial assets in the United States. In a nutshell, the nation's
economy remains strong despite its slowdown in the second half of the year.
Short-term interest rates are expected to remain low -- the federal funds rate
is holding at 5.5 percent and will most likely stay put for the remainder of the
year. There are no major tax or regulatory threats waiting in the wings. And our
economy continues to draw investors from around the world, although perhaps not
as fervently as last year.
  The nation's gross domestic product (GDP), which represents the total value of
all goods and services produced within the U.S. economy, grew at an annualized
rate of 1.4 percent in the second quarter of 1998. While this was the slowest
growing quarter in the last three years, it was much stronger than consensus.
Slower growth can be attributed to several factors, including the impact of
decreased trade with Asia, domestic corrections in inventory levels and the
General Motors strike, which has since been resolved.
  Real capital spending and employment growth have remained solid. Consumer
confidence remains fairly high. Home sales remain robust. Economic policy
continues to support the nation's fiscal budget surplus projection of $65
billion.
  As far as inflation goes, there are two tales to be told. Prices for consumer
goods, as measured by the consumer price index (CPI), are steady. Compare this
to prices for services, which have risen between 3 and 4 percent. For investors,
this difference in pricing flexibility translates into a difference in profit
expectations. Profits of domestic service firms should be much stronger than
commodity producers dependent on export markets.
  Across the Atlantic, Europe's economy appears to be growing at an even pace as
the region progresses toward the Economic and Monetary Union (EMU) slated for
January 1, 1999. One effect of the union may be a slight rise in short-term
interest rates in Europe -- not because there will be an overt change in policy,
but simply because of the convergence of some very disparate interest rates. The
average rate will likely be higher than the relatively attractive rate the
German Central Bank currently offers, for example.
  In Asia, which has been making headlines around the world for more than a year
now, the latest news is from Japan, which recently installed a new prime
minister as well as a new finance minister. Much discussion will be focused on
changes in Japan's economic policy, particularly in terms of taxation and
banking reform -- and patience is in order. Most of the changes in taxation will
impact Japan in the first half of 1999. But as far as banking reform goes, those
of us familiar with bank reform in the U.S. know that this will be a two- to
five-year process. Certainly, investors are looking to Japan to spark recovery
for Asia as a whole, which continues to suffer from the "contagion" of low
currency values, seriously reduced consumer spending and general economic
malaise.
  Indeed, while its full effects remain to be seen -- and felt -- by the
majority of American businesses and individuals, the Asian economic crisis has
contributed to the general uncertainty of the emotion-driven U.S. markets.
Whether it's an economic crisis abroad or political scandal at home, current
events move the investors who move the markets.
  One might conclude that, as a result of today's low corporate profits and
lingering turmoil in Asia, the psychology of the markets is shifting -- even
some of Wall Street's most resolute bulls appear to be reconsidering their
long-held convictions. But with the economy's strong fundamentals in place, that
outlook may be premature. In any case, prudent investors are wise to watch for
the following economic warning signs: inflation in the form of rising wages
and/or prices; residual fallout from Asia, which

could appear in the form of reduced sales and earnings for American businesses;
and a continued widening of our trade deficit, an imbalance caused by heightened
American demand for foreign goods and services. In the months to come, investors
are likely to maintain their bias in favor of investments that have historically
been considered more conservative: larger capitalization stocks, U.S. Treasuries
and only the highest-grade corporate bonds.

your investment needs.

MANAGEMENT SUMMARY
 
KEMPER MONEY MARKET PORTFOLIO
 
  Stability has been the cornerstone of the money markets recently. Federal
Reserve policy has been on hold with a target for Federal Funds anchored at 5.5
percent. Countervailing economic considerations include inflation measures,
which have been well behaved, and the much publicized Asian problems that are
expected to place a drag on U.S. growth.
  On the other hand, the economy continues to show resilient strength as
ultimately measured by Gross Domestic Product and specifically by robust housing
and employment statistics, the Index of Leading Economic Indicators, consumer
confidence and a stock market that has performed admirably.
  In general, we maintained a defensive, short-average-maturity strategy
throughout much of the period. This was based on our outlook that interest rates
would perhaps remain flat or rise through time, and the yield curve offered no
income reward for lengthening the portfolio. Events unfolded as expected and we
were able to take advantage of developing market opportunities.
  Going forward, our investment strategy will embody a neutral-average-maturity
policy, which will provide the flexibility to react quickly to developing market
opportunities. In this light, the Federal Reserve is expected to hold the line
on interest rates into 1998, the Asian crisis impact has been modest thus far,
inflation measures are likely to rise from current levels and we will have
little income incentive to extend the portfolio.

KEMPER TOTAL RETURN PORTFOLIO
 
  The growth in equity markets this year was led by large capitalization stocks,
creating a relative valuation disparity that was extreme. As a whole, those
stocks that outperformed had minimum exposures to economic cyclicality and/or
the Far East. Asia had a significant near-term impact on the earnings growth
rate of domestic companies, which led to a disparity among individual stock
valuations. While some issues did well, others did not, creating many
opportunities to identify attractive, undervalued investments.
  As active stock managers, we continually sift through various candidates to
identify those offering "growth at the right price." Among those that performed
well for us last year were General Electric, which also outperformed this year
and continued its history of consistent earnings, as well as Time Warner and
selected other large capitalization issues in the pharmaceutical and financial
sectors.
  We still have a full weighting in the financial sector, but have leaned more
toward opportunities in the insurance side, where we expect consolidation
similar to what has happened in the banking industry as financial institutions
merged for economies of scale. Likewise, we have been selective in the
technology area, experiencing our biggest gains from leaders like IBM and
Computer Sciences Corp., both specializing in computer services and consulting
particularly with year 2000 issues looming.
  We tried to stay clear of cyclically sensitive stocks, including those in the
capital goods, transportation and industrial sectors, which have been hit hard
in the recent period.
  As a Total Return Portfolio, we have the flexibility to shift assets into
bonds, which we did as certain stocks met our price targets. Bonds now
constitute 35% of total assets.
  However, given the overall disparity in values in the market now, the
environment is good for stock pickers like us. Many stocks have corrected
significantly, but we will continue to be selective about adding them to the
portfolio. Overall, though, we see opportunity despite the unusual conditions,
and will continue to leverage those opportunities for our investors.
 
Maureen P. Lentz
Lead Portfolio Manager


KEMPER HIGH YIELD PORTFOLIO
 
  The Asian crisis has not yet had a major impact on high yield bond issuers,
most of whom would be considered "small cap" and conduct business primarily in
the United States. We do believe, however, that all of the effects of Asia have
not yet been felt by the U.S. economy. We do not expect the impact to be severe,
but we will watch it closely and monitor its effects on the U.S. economy and the
high yield market.
  Much of the new supply in the high yield market is in lower-quality bonds
(C-rated and non-rated issues). Lower credit implies more risk, but these bonds
offer higher yields to compensate for the assumed higher risk. Therefore, it is
more difficult to find higher-quality bonds today.
  We have been investing more in lower-quality issues than we were a year ago,
but not simply because they are what is available. Instead, these issues make
sense given the current strength of the economy, which gives weaker credit a
great chance to flourish. When we sense the economy is beginning to shift, we
will change our strategy.
  All indicators point to continued strength in the high yield market. Defaults
remain relatively low and supply and demand continue to grow at a breakneck
pace. For both income-oriented and total return-oriented investors, the high
yield market may make a great deal of sense right now, relative to the domestic
stock market.

MANAGEMENT SUMMARY
 
KEMPER GROWTH PORTFOLIO
 
  There were two countervailing forces in the market recently. First, the
domestic economy continued strong, with low interest rates, low inflation, good
profitability and no excesses. On top of that, however, was the Asian economic
crisis and the resulting "Asian flu," which spread worldwide and ultimately
brought uncertainty to many areas of the U.S. market.
  That uncertainty has 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 in
the first tier and the rest of market is the widest in many decades.
  For GARP investors like us -- those who seek "growth at a reasonable price" --
this has been a difficult market. Many of the stocks that we hold or might
consider holding have simply marked time. Nonetheless, we have found many
opportunities for growth at the right price that we expect to perform well once
the market moves on to a more balanced and reasonable stage.
  In the technology sector, for example, we've found very good opportunities
among semiconductor manufacturers, personal computer makers and software service
companies. Likewise, in the financial services sector, we are seeing very good
growth rates relative to value among money center banks and regional banks.
We're also finding buys in consumer stocks in the retail area and auto parts
areas.
  Going forward, we look for stabilization in southeast Asia, which should
return confidence to a number of the industrial areas and lead the market to
broaden out. Once uncertainty is removed from many areas of the market, we
expect our holdings to move onto higher, healthier ground quickly. We believe we
are well positioned for that change.

Lead Portfolio Manager


 
KEMPER GOVERNMENT SECURITIES PORTFOLIO
 
  The big story over the past year has clearly been the Cinderella economy, in
which we've seen four percent growth, continually reduced inflation and a stable
Federal Reserve Board policy. That, combined with a Federal budget surplus and
economic troubles in Asia, conspired to push interest rates lower late last
year.
  Faced with a falling interest rate environment, we worked to maintain a
relatively aggressive profile, lengthening our portfolio duration and making
substantial allocations to select mortgage issues. By January, however, we
believed that the market had fully priced the Cinderella scenario and we moved
the portfolio toward a neutral duration.
  At mid-year, we again extended duration. Asia continued to be problematic and
Japan seemed unwilling to deal with its troubles, and because of the effect that
was likely to have on the U.S. economy, we felt that Federal Reserve policy
would continue to hold steady.
  Going forward, we are cautiously bullish about the market, although we
recently reverted to a neutral duration to reflect a degree of uncertainty.
Overall, we believe there is still room for further reductions in interest
rates. If you compare yields here to comparable yields in other developed
countries, such as Germany and especially Japan, the U.S. is considerably
cheaper. So from a global perspective, U.S. bonds are attractive right now and
should continue to bring in investors worldwide and more opportunities for the
portfolio.
 
Richard L. Vandenberg
Lead Portfolio Manager
 


KEMPER INTERNATIONAL PORTFOLIO
 
  The keys to our strong performance recently were several. First was our heavy
weighting in Europe. Europe is currently seeing accelerated economic growth
coupled with rapidly rising corporate profitability. Within the continent, we
have focused the portfolio into companies that are either restructuring
themselves and becoming more efficient, or companies with very strong franchise
values that are benefiting from growth in the region.
  Overall, we continue to see Europe as the single strongest region next to the
United States. We have also seen some very good growth companies selling for
very reasonable prices in Canada.
  Another benefit to portfolio performance was our underweighting in certain
regions, most notably southeast Asia. We had almost no money in the region at
the time of the economic decline, and we intend to avoid the area until we see
signs of economic improvement. Likewise, we are not heavy in Japan, which has
been a very ordinary performer, although we hold a number of individual stocks
of companies that are globally dominant in their sectors. Another region we have
lightly weighted is Latin America, which has been a poor performer and is
slowing economically.
  Globally, we expect to see inflation remain very benign in the months ahead.
That means interest rates should be flat to down, which is good news for equity
investors and keeps us reasonably bullish, especially on markets where the
underlying economic situation is quite positive. Going forward, we will continue
our longstanding practice of picking stocks, not regions, which we believe is
the most reliable way to find good values and continue sound portfolio
performance.

MANAGEMENT SUMMARY
 
KEMPER SMALL CAP GROWTH PORTFOLIO
 
  With the economy growing at slower rates and the Asian crisis having a
negative effect on some sectors, we continue to search for small capitalization
companies that exhibit predictable earnings growth. With small cap stocks
continuing to lag their large capitalization counterparts, relatively good
values can be found in the portfolio's investment universe.
  Over the past several months, the portfolio has emphasized stocks in the
broadcasting, education and consumer sectors. We believe that select equities in
these groups should continue to perform well in the low-interest-rate,
moderate-growth economic environment.
  Although we believe that equities in the technology sector will be an
important part of the portfolio's long-term focus, we continue to underweight
that group in the current environment. The Asian economic crisis, combined with
overcapacity in the semiconductor sector, resulted in reduced expectations for
hardware-related companies. We currently emphasize quality software, service and
consulting companies. We are looking for better buying opportunities in personal
computer, semiconductor and other hardware equities.
  Noteworthy changes in the portfolio recently include an increased weighting of
the education sector, including new positions in Sylvan Learning and ITT
Education, both of which are largely unaffected by changes in the economy. We
also took a new position in American Tower, the largest independent owner of
communication towers in the U.S. We sold our holdings in Triangle Pacific after
an announcement they will be purchased by Armstrong World.
 
David Burshtan
Lead Portfolio Manager
 


KEMPER INVESTMENT GRADE BOND PORTFOLIO
 
  A major event in the bond markets recently was the brief but significant
downturn in corporate bonds back in January. There were two reasons behind this:
a continuing lack of investor confidence caused by the ongoing economic turmoil
in southeast Asia, and an enormous supply of corporate bonds in the market
without strong demand.
  Anticipating the tension in the Asian market, we reduced our exposure to the
most illiquid and volatile corporate assets as far back as October 1997. That
gave us confidence that January's downturn was not indicative of the strength of
our corporate holdings, but instead a short-term market event. With that in
mind, we decided to ride out the storm rather than decrease our exposure to
corporate bonds. And our patience was quickly rewarded: Within two months we had
erased the January loss and were back where we wanted to be.
  After recovering from the downturn, we began reducing our corporate holdings
to take advantage of opportunities in other sectors of the bond markets,
including mortgage investments, which help enhance the portfolio's income level.
  Our largest payoff during the period was from issues we hold in the banking
industry. We had a fairly substantial bank position that benefited from two
merger announcements in April as well as ongoing industry consolidation. Many
other financial service issues we hold performed quite well on the coattails of
those events.
  As long as the economy continues to grow moderately and there are no signs of
a recession, the corporate market should remain resilient, delivering good
returns relative to Treasuries. In that event, the portfolio should continue to
stay its current, steady course in the months ahead.
 
Robert Cessine
Lead Portfolio Manager
 


KEMPER CONTRARIAN VALUE PORTFOLIO
 
  Over the last six to nine months, the U.S. stock market has been in a "Nifty
Fifty" mode, meaning a select group of the largest capitalization stocks --
particularly those that are growth oriented and have good fundamentals -- have
done much better than the average stock. In fact, many stocks are currently 20
or 30 percent off their highs, which we believe indicates the market is
currently experiencing a correction.
  Almost by definition, this "Nifty Fifty" phenomenon favors stocks in which the
Contrarian Value Portfolio won't invest. Nonetheless, we've been pleased with
our performance to date and feel that, when an upward trend in the markets
arrives, the portfolio will be well positioned for it.
  Despite current conditions, the basic structure of our portfolio hasn't
changed significantly. We continue to overweight financial stocks using a broad
array of money centers, regional banks, and insurance and financial services
companies. We feel that the combination of attractive valuations and strong
earnings growth is still fairly powerful in this group. We also have a
meaningful weighting in basic materials stocks, such as diversified forest
products, paper, chemicals and steel as well as the energy group. On the other
side of the coin, we have been underweighted in utility stocks, health care
stocks and technology stocks.
  The overall tone of the market means investors need to exhibit greater caution
and care than usual and recognize the environment in which they are operating.
There are good companies out there that meet our philosophy and have very
attractive one- to three-year rates of return. We are ready to step in and buy,
even though there may be a short-term downside.

MANAGEMENT SUMMARY
 
KEMPER SMALL CAP VALUE PORTFOLIO
 
  The recent period has proved difficult for small capitalization stocks in
general, and value-oriented funds specifically. Under normal conditions, value
funds do not tend to suffer the effects of a downturn as acutely as growth
funds, but in the quasi-bear market we've seen recently, that has not been the
case.
  The sluggish performance of small cap stocks has been due in large part to
three factors: the current deflationary environment, an extremely strong U.S.
dollar and the troubles in Asia, ripples from which have trickled down through
large multinational corporations to impact many of the stocks in which this
portfolio invests. Some of the sectors that have not performed to our
expectations include energy, capital goods, financial services and even health
care.
  Nonetheless, we have had many success stories, predominantly among our larger
holdings. A few stocks in the communications sector -- notably Jones Intercable
and Young Broadcasting -- had a very good year, as did selected holdings in the
capital goods, technology and education areas.
  Looking forward, we feel the valuation gap between large caps and small caps
will narrow. It's just a question of when. Small caps have been out of favor for
two years, but we still feel something significant must change to tip the
balance, whether it's the return of inflation or an improved outlook for Asia.
  Overall, we feel we have an undervalued portfolio composed of solid companies,
making us well positioned for the future. We will continue to take a bottoms-up
approach to stock picking, identifying companies with considerable value
relative to the market. We expect that strategy to serve us well when small caps
gain back their strength.
 
Thomas H. Forester
Lead Portfolio Manager
 


KEMPER VALUE+GROWTH PORTFOLIO
 
  Overall, the market posted brisk returns during the past year, but investors
have had to hold tight through a period of ups and downs. "Gray Monday," October
27, 1997, was the most severe but not the only market turbulence investors would
experience during the period. Worries about Asia, earnings disappointments and
an uncertain Fed policy all helped stir the waters.
  Generally, growth stocks outperformed value during the period, domestic stocks
were more attractive than international ones, and large company stocks fared
better than smaller ones. The changing tides of the markets were often
unpredictable. During this fast-paced period, we steered the portfolio by
focusing on individual stock selection.
  Recently, the lion's share of the portfolio's assets were allocated toward
growth stocks, based on our evaluation of macroeconomic factors. As growth
outperformed value for much of the period, that decision proved to be the wise
one.
  Specifically, consumer nondurable stocks enjoy the largest portion of the
portfolio, followed by finance, technology and health care. Given the
macroeconomic conditions, we've looked for openings to position the fund
defensively, and several of our consumer nondurable holdings lived up nicely to
that sector's reputation of greater resiliency in times of turmoil.
  We expect volatility will continue, especially because there haven't been
sufficient indications that the turmoil in Asia is anywhere near completion.
Yet, overall, we continue to believe in the long-term potential of domestic
equity investing. We look for more restrained domestic corporate earnings to set
a slower, saner pace in the coming months.
 
Philip S. Fortuna
Lead Portfolio Manager
 


KEMPER HORIZON 20+, HORIZON 10+ AND HORIZON 5 PORTFOLIOS
 
  The past year has been a volatile one for investors. Currency turmoil in Asia
sent global markets into a tailspin, resulting in part in "Gray Monday," October
27, 1997, when the Standard & Poor's 500 declined seven percent. Domestic equity
markets rebounded quickly, however, before settling into the tides of periodic
volatility that have characterized 1998.
  In addition to the Asian crisis, concerns about an interest rate hike also
dogged the market during the early portion of the year. There have been plenty
of disappointing earnings stories, particularly among smaller companies and
technology stocks.
  With the portfolios this year, our bond stake helped to provided protection
against market turbulence. Our fixed-income allocation is quality focused and
currently holds an average credit rating of AAA. We've invested in U.S.
Treasuries and mortgage-backed securities, and although the fund can invest in
high yield bonds, we have recently opted to eschew that area.
  The portfolios' domestic equity exposure is divided between growth and value
stocks, and we have been steadily increasing the growth/value mix to 70/30 from
60/40. The change has paid off. In the current market, growth stocks have been
rewarded more handsomely than their value counterparts. We were also well
positioned with the portfolio's international stake, favoring Western European
holdings over Asian ones.
  Going forward, we continue to adhere to our disciplined, quantitative focus.
We think that, over the long term, keeping clear-sighted and cool-headed is the
most sensible course. In fact, we plan to implement more formal quantitative
techniques to uncover and pursue attractive opportunities in the markets.

MANAGEMENT SUMMARY
 
KEMPER BLUE CHIP PORTFOLIO
 
  Overall, the stock market posted strong gains during the period, but not
without volatility along the way. At the same time, the market favored large cap
stocks over smaller company issues, and the U.S. outperformed international
markets. These gains were made in a choppy and rotational market climate. If
nothing else, the past period proved the importance of keeping a long-term
focus. Investors who held on ended up with tidy gains.
  Our performance was attributable to several factors, one of which was our
ability to anticipate the crisis in Asia. The portfolio had limited exposure to
troubled Asian markets. However, because the Asian turmoil drove down the prices
of many quality stocks, we used the period as a domestic-issue buying
opportunity.
  Some of our notable acquisitions included technology issues we believe to be
undervalued, such as Hewlett-Packard and IBM, and cyclical stocks, including the
chemical companies PPG Industries and Imperial Chemical Industries.
  Apart from stocks impacted by Asia, we found good values in insurance names,
an industry which is trending toward consolidation and should continue to gain
appeal. We also built up a small position in real estate investment trusts
(REITs) to help bolster yield.
  Going forward, we continue to be very positive about the long-term growth
prospects of the U.S. equity markets. Investors, however, need to be prepared
for ups and downs. By taking a stock-by-stock approach, we are confident that
our focus on well-researched, large cap companies will continue to provide
shareholders with a more reliable investment vehicle.

KEMPER GLOBAL INCOME PORTFOLIO
 
  In the first half of the year, global bonds performed well in terms of local
currency. For example, the first-half return for the Salomon Smith Barney World
Government Bond Index was 4.28 percent, while the same index in U.S. dollar
terms was 2.79 percent. This difference was due to the strength of the U.S.
dollar against the Japanese yen, the Australian dollar and the Canadian dollar
- -- all currencies affected by the Asian economic crisis.
  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 the
Australia, New Zealand and U.K. markets and underweight in the United States,
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 because of higher expected
returns.
  The portfolio maintained a long-term focus and we remained committed to
government and supranational bonds with very high credit quality. Fifty-six
percent of the portfolio was AAA bonds and the rest was AA. The average duration
was just over five years throughout the period.
  The benign background to bond markets remains in place and the managers'
return forecasts are, on average, positive for government bond markets in the
developed world. Bond yields have declined in tandem with inflationary
expectations in many countries and many markets are fairly valued overall.
Despite high first-quarter growth in the U.S., the market does not expect the
Federal Reserve Board to tighten policy, and the Bundesbank is not expected to
tighten until at least the fourth quarter.

KEMPER-DREMAN HIGH RETURN EQUITY PORTFOLIO
 
  The strong performance of the Standard & Poor's 500 embodies what has happened
in the markets since the volatility of October 1997: earnings announcements
continued to be strong, and investors grew confident that problems in Asia
wouldn't have a significant impact. But in May, additional concerns about the
yen triggered more turbulence, and the market retraced a portion of its previous
advance. Only the largest growth companies held onto their gains.
  That, combined with the High Return Equity Portfolio's large holdings in oil
and tobacco, led to a measure of underperformance in the first part of 1998.
However, we believe both sectors are compelling buys over the longer term. The
tobacco sector offers solid companies -- most notably Phillip Morris -- that are
selling for far less than their intrinsic value. In the oil sector, we're seeing
price pressure on certain stocks because of an 11-year low in oil prices, which
has created some outstanding buying opportunities.
  Financial stocks remain the portfolio's largest sector weighting. While they
have lagged the market a bit in 1998, we still see a number of values there.
Currently, we are concentrating on regional banks involved in mergers we believe
will result in earnings expansion.
  In the months ahead, we feel that volatility will continue and may even
intensify. Volatility, however, creates opportunity for contrarian investors. An
irrational market is likely to punish good stocks as well as bad ones, and that
is an opportunity to add real long-term value for our shareholders.

MANAGEMENT SUMMARY
 
KEMPER-DREMAN FINANCIAL SERVICES PORTFOLIO
 
  The financial services sector proved itself one of the best performing areas
of the stock market in the last year, fueled largely by bank mergers and
insurance companies. In March and April, the sector continued to outpace the
market, but it took a breather in May as investors grew concerned about the
prospects for higher interest rates. Nonetheless, we believe the sector offers
many of the characteristics that attract value managers and offers more than its
share of solid, long-term opportunities.
  Recently, we have emphasized regional banks, which we believe will continue to
be the beneficiaries of the trend toward consolidation. We focus on the
regionals because their mergers are more symbiotic than the mega-mergers between
huge institutions. For example, at the regional level, each bank can gain
services or outlets that they previously lacked. In addition to that area, we
have also looked at smaller insurance companies with good track records, which
are harder to buy but worth the effort.
  In the months ahead, we expect to see more volatility in the sector, in part
due to weakness in the Japanese yen and the potential for an additional round of
currency devaluations in Asia, all of which could spook U.S. markets. On the
upside, though, that volatility could present more chances to buy stocks that
might be unjustly out of favor -- for example, certain banks that do not do
business overseas.
  Overall, we intend to apply our strict valuation criteria and look for those
financial services companies that are believed to offer limited downside
potential with the opportunity for a very strong upside.

KEMPER GLOBAL BLUE CHIP PORTFOLIO
 
  On the global stage, continental Europe has recently proved itself a real
star. In part, the region is benefiting from a friendly interest rate
environment, created to facilitate completion of the European Monetary Union on
January 1, 1999. Furthermore, there is a growing perception -- reflected by the
market -- that European corporations are rapidly developing a new, more
productive view of the world.
  With that in mind, European restructuring remains the premier theme within our
portfolios and has been a major contributor to returns. We see strength and
opportunity continuing for some years to come. However, it is an idea that is
now well appreciated by investors.
  Our second most heavily weighted theme is "secure streams of income." In
addition to our past income-oriented investments in U.S. Treasury bonds and
electric utilities, we have recently added Lockheed Martin, whose profits are
underpinned by an increasing defense budget and a strong internal efficiency
plan. We have also initiated a position in American Greetings, whose long record
of success may be enhanced by some new product initiatives.
  A key question for the portfolio team going forward is whether our
European-oriented themes are nearing maturity given the market's enthusiasm for
these stocks and their resulting valuations. Our response to this challenge has
been to identify companies whose valuations fully reflect their restructuring or
earning potential, and thus are potential sell candidates. Ultimately, however,
the best judge of value is the attractiveness of alternative investments. And
the search for those, as always, prompts us to examine what is going on in the
broader global context.

KEMPER INTERNATIONAL GROWTH AND INCOME PORTFOLIO
 
  Since the portfolio's inception on May 5, 1998, we've seen a number of events
of historic proportions. First among these was the formalization of the European
Monetary Union, which will result in a single currency at the start of 1999 and
the first significant step toward political unification on the continent.
  The long-term benefits of this momentous event were not overlooked by the
European stock markets, many of which were up over 40 percent for the first six
months of the year. In anticipation of that opportunity, the International
Growth and Income Portfolio had a significant overweighting in the European
markets, and we profited accordingly.
  Specifically, we sought out those sectors best positioned to benefit from some
of the positive changes occurring in the region, including the banking,
insurance and telecommunications industries. While we expect some profit-taking
in the markets, the long-term picture for Europe and its markets is better than
it has been for decades.
  At the same time, Japan in the past six months continued to suffer from
political gridlock and an inability to address the crisis in its banking sector.
The country's economy, currency and stock market all reflected this turmoil,
making Japan a region to avoid except for a few highly selective buying
opportunities. Likewise, we underweighted the emerging markets -- including
southeast Asia -- despite a rally in the first quarter that quickly proved
fleeting.
  In the months ahead, the portfolio's focus will continue to be on relative
yield -- the universe of stocks offering 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.

                             foreign securities exchanges are generally valued
                             at the preceding closing values of such securities

                             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. Exchange traded 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.

                             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 securities of the Kemper Total Return, Kemper
                             Horizon 20+, Kemper Horizon 10+, Kemper Horizon 5,
                             Kemper Blue Chip, Kemper-Dreman High Return Equity,
                             Kemper-Dreman Financial Services, Kemper Global
                             Blue Chip and Kemper International Growth and
                             Income 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 Nasdaq for which there
                             have been sales, are valued at the most recent sale
                             price reported on Nasdaq. 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 shall be used.

NOTES TO FINANCIAL STATEMENTS
 
                             Portfolio debt securities other than money market
                             securities with an original maturity over sixty
                             days 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. Money market instruments
                             purchased with an original maturity of sixty days
                             or less are valued at amortized cost. If it is not
                             possible to value a particular debt security
                             pursuant to the above methods, the investment
                             manager may calculate the price of the debt
                             security, subject to limitations established by the
                             Board. An exchange-traded options contract on
                             securities, currencies, futures and other financial
                             instruments is valued at its most recent sale price
                             on such exchange. If no sales occurred, the options
                             contract is valued at the calculated mean. If there
                             is no calculated mean, the options contract is
                             valued at the most recent bid quotation in the case
                             of a purchased options contract, or the most recent
                             asked quotation in the case of a written options
                             contract. An options contract on securities,
                             currencies and other financial instruments traded
                             over-the-counter is valued at the most recent bid
                             quotation in the case of a purchased options
                             contract and at the most recent asked quotation in
                             the case of a written options contract. Futures
                             contracts are valued at the most recent settlement
                             price. Foreign currency exchange forward contracts
                             are valued at the value of the underlying currency
                             at the prevailing exchange rate. If a security is
                             traded on more than one exchange, or upon one or
                             more exchanges and in the over-the-counter market,
                             quotations are taken from the market in which the
                             security is traded most extensively. If, in the
                             opinion of the Valuation Committee of the Board of
                             Trustees, the value of a portfolio asset as
                             determined in accordance with these procedures does
                             not represent the fair market value of the
                             portfolio asset, the value of the portfolio asset
                             is taken to be an amount which, in the opinion of
                             the Valuation Committee, represents fair market
                             value on the basis of all available information.
                             The value of other portfolio holdings owned by a
                             Fund is determined in a manner which, in the
                             discretion of the Valuation Committee most fairly
                             reflects fair market value of the property on the
                             valuation date.
 
                             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.
 
                             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 rate 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 and
                             includes discount amortization on fixed income
                             securities. 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 June 30, 1998, the Kemper
                             Government Securities Portfolio had $13,522,000 of
                             purchase commitments outstanding (14% 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 the Exchange for all Portfolios (excluding the
                             Kemper Money Market Portfolio) and at 11:00 a.m.
                             and as of the earlier of 3:00 p.m. Central time or
                             the close of the Exchange 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's
                             does not take place contemporaneously with the
                             determination of prices of the Portfolio's foreign
                             securities.
 
                             FEDERAL INCOME TAXES. Each Portfolio has complied
                             with the special provisions of the Internal Revenue
                             Code available to investment companies for the six
                             months ended June 30, 1998. The accumulated net
                             realized loss on sales of investments for federal
                             income tax purposes at June 30, 1998 amounted to
                             approximately $15,769,000 in the Kemper High Yield
                             Portfolio, $4,453,000 in the Kemper Government
                             Securities Portfolio and $150,000 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.

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. Prior to January 1, 1998, the
                             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 per share portion of the proceeds from
                             sales and the cost of redemptions of fund shares to
                             undistributed 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 book equalization will result in simpler
                             financial statements. The cumulative effect of the
                             change was to increase (decrease) undistributed net
                             investment income and increase (decrease) paid-in
                             capital previously reported through December 31,
                             1997 for the following Portfolios by the following

                             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 June
                             30, 1998, the market value of assets pledged by the
                             Portfolios to cover margin requirements for open
                             futures positions was $50,000, $80,000, $30,000,
                             $30,000, $88,000 and $123,000 for the Kemper
                             Value+Growth, Kemper Horizon 20+, Kemper Horizon

                             respectively. The Portfolios also have liquid
                             assets in their portfolios in excess of the face
                             amount of open futures contracts. At June 30, 1998,
                             the Portfolios had the following futures contracts
                             open, with expirations in September, 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 June 30, 1998,
                             the Portfolio had the following forward currency
                             contracts outstanding with settlement dates in July
                             and September, 1998:
