DEAR CONTRACT HOLDER,
 
A self-regulating economy, a balanced budget agreement and a positive stock
market all have contributed to another excellent year for investors. Given the
extended length of today's bull market (which celebrated its 15th anniversary on
August 12), it is prudent to wonder whether the end is near. Our position is
that while there is a certain precariousness to today's environment, which we
will elaborate on below, we see little to suggest that there will be more than
occasional market corrections.

  Bipartisan agreement to balance the federal budget by the year 2002 represents
significant progress that should benefit investors over the long term. By
reducing the burden of capital gains and eliminating certain tax loopholes, the
Taxpayer Relief Act of 1997 and the Balanced Budget Act of 1997 have the
potential to meaningfully affect behavior. Now that the ceiling has been raised
on capital gains from the sale of a home, empty nesters will be more inclined to
move out of homes and into smaller condominiums. Added investment and savings
options should help boost the country's sagging savings rate. From a social
perspective, government's action to widen the difference between the taxation
rate on capital gains and on income reflects a conscious effort to encourage
capital investment. The more people and businesses can do for themselves, the
less likely they are to rely on the government, which should help restrain
federal spending.

  The maximum tax on long-term capital gains is now 20 percent versus a maximum
of approximately 40 percent on ordinary income earned by Americans in the
highest income tax brackets. This dramatic difference could have some influence
on the management of mutual funds in the future. Although few investment
decisions are based on their tax consequences, the legislation supports a "buy
and hold" approach to investing, by which a mutual fund generates investment
returns through gains on investments held 18 months or longer. Such gains are
taxed at the reduced capital gains rate. On the margin, portfolio managers
should focus on long-term investing -- the strategy that we have always
supported.

  In addition, mutual funds will gain investment flexibility with the new law's
repeal of what has been called the "short/short rule." Previously, investment
companies had been subject to a 30 percent limitation on total income arising
from the sale of securities held less than three months -- or face severe tax
consequences. The lifting of this limitation provides newer funds, in
particular, with much needed maneuvering ability.

  You can expect to hear more from Kemper about the implications of the new
legislation, and specifically about the tax reporting changes, over the next
several weeks and months. Overall, we believe that this legislation is something
the country can be proud of. It represents years of a commitment on the part of
the federal government to hold spending in check and refrain from creating new
programs. Expanding corporate revenues and profits in an extended period of low
inflation also contributed to making this investor-friendly environment
possible.

  As we look toward the end of the year, we see little to trouble us. The
economy appears to be in excellent condition. Continuing the alternatingly
fast/slow pace that we have experienced for several months, the fast-growing
first quarter was followed by a slower second quarter. Such self-regulation has
minimized any need for the Federal Reserve Board to raise interest rates again.
We don't rule out the possibility of another hike in the fourth quarter,
however.

  Inflation is very low. In spite of unemployment being the lowest we have seen
in decades, wage pressures are still manageable. For example, the United Parcel
Service strike and the earlier steel and airlines work actions represent the
most union activity we have seen in 10 years. Encouraged by the low unemployment
(and therefore high demand for workers), the unions are becoming bolder but in
the end seem ready to resolve disputes sensibly. As a consequence, wage
increases remain moderate.

expansion or credit crunch have a significant impact on mutual fund performance.
     The following are some significant economic guideposts and their investment
rationale that may help your investment decision-making. The 10-year Treasury

  Our primary concern is the very high valuations of the stock market. All
things considered, it is difficult to see where we can go from here. With prices
at such heady levels, the market can be expected to react negatively to even
minor earnings disappointments, as we have seen in August. Kemper's response to
this market is to remain fully invested and to reduce exposure by diversifying
across a wider group of investment opportunities. Research, the first step in
stock selection, is key in this kind of a market.

  Bond markets are obviously cheered by recent events, and prospects for income
investors continue to be positive. Interest rates are stable and credit quality
has not been an issue. A dwindling supply of municipal bonds has enabled
municipal investments to outperform U.S. Treasuries.

  In such a fully valued domestic market, it can make sense to look to
international markets for their growth potential. The strength of the dollar
thus far this year has diminished returns but international opportunities look
bright.

  With this commentary as an economic backdrop, we encourage you to read the
following detailed report. Thank you for your continued support. We appreciate
the opportunity to serve your investment needs.
 
Sincerely,

MANAGEMENT SUMMARY

KEMPER MONEY MARKET PORTFOLIO
- ------------------------------------
 
  Early in the new year, the economy registered signs of vigor and economic data
was strong. This upswing led to speculation that the Federal Reserve Board (the
Fed) would tighten monetary conditions to guard against increased inflation. The
possibility of a rate adjustment caused a steepening of the yield curve and
slightly higher yield levels. In late March, the Fed did increase rates by 25
basis points despite the lack of inflationary pressures. Following the rate
hike, concerns over the possibility of further tightening continued to affect
yields, but to date inflation has not increased and we do not anticipate the Fed
to take action until a definite rise is seen.
  With moderate economic growth and modest inflationary pressures, we remained
somewhat defensive with maturities. We adjusted holdings to take advantage of
any opportunities the market provided.
  Looking forward, we anticipate uninterrupted, moderate economic growth coupled
with subdued but rising inflationary pressures. With this in mind, we do expect
the Fed to consider increasing rates again in the second half of the year. The
economic recovery is continuing and based on recent statistics, its momentum
appears to remain strong. Labor markets have firmed as measured by employment
statistics, consumer confidence is high and quarterly measures of the gross
domestic product should be above trend for a non-inflationary expansion.

KEMPER TOTAL RETURN PORTFOLIO
- ------------------------------------
 
  The stock market during 1997 can be characterized as very strong but volatile.
The market has seen days of dramatic increase only to see the gains taken away
the next day. The portfolio began the year overweighted in technology, financial
and health care stocks. These sectors all performed very well and we began to
take profits. As we trimmed back our technology holdings we did, however,
maintain our weighting in software stocks. We feel that they will do well as
significant expenditures will need to be made as the year 2000 approaches. Stock
selection remained the key for us this year, as we continue to aggressively
apply our growth at the right price (GARP) strategy.
  The bonds in the portfolio have basically been earning their dividend and the
prices have stayed relatively flat. We have been purchasing more bonds because,
as the stocks continue to appreciate, we need to add bonds to maintain our
current 65% stock and 35% bond mix. We have added government bonds for quality
and increased our exposure to high yield bonds to pick up yield. The 35% bond
commitment is not a barometer of our outlook on the stock and bond markets, but
rather a risk reducer.
  Going into the second half of the year, we have become a bit more defensive.
In addition to trimming back our technology holdings, we have also begun to
build up our consumer retail holdings; this is in anticipation of an increase in
consumer spending.

KEMPER HIGH YIELD PORTFOLIO
- ------------------------------------
 
  High yield bonds performed well throughout most of the six-month reporting
period. There was, however, a brief correction in March after the Federal
Reserve Board (the Fed) raised short-term interest rates by 0.25 percent. As a
result of the rate hike and concern about the historically tight spreads in the
market, the market sold off, causing spreads to widen and high yield values to
fall somewhat.
  In anticipation of the Fed's intervention, we reduced the fund's level of
BB-rated bonds. BB-rated bonds are the highest quality securities that are still
considered to be high yield, or below investment grade bonds. Reducing our BB
holdings made sense because the closer a bond is to an investment-grade
security, the more it tends to perform in-line with interest rates.
  Since March, high yield bonds have bounced back, posting positive returns
throughout the remainder of the period. Economic growth remains slow but
consistent, which is positive for companies issuing high yield debt. Slow
economic growth generates consumer spending, which fuels earnings and enables
companies to meet their coupon payments. Growth at a controlled rate tends to be
fundamentally good for high yield bonds.
  The current low rate of defaults in the high yield market is also very
positive for high yield investors because it means the coupons on high yield
investments are being paid consistently. The lack of defaults can be attributed
to the economic expansion the U.S. has been experiencing over the last six
years. The economy has been growing slowly but consistently and inflation
remains relatively benign. Economic growth, low

MANAGEMENT SUMMARY
 
inflation and a lack of defaults are critical components of a healthy high yield
market and, although markets can change at any time, we're now experiencing all
three. For these reasons, we remain bullish about the high yield market.

KEMPER GROWTH PORTFOLIO
- ------------------------------------
 
  Technology stocks and large capitalization stocks have driven the market this
year. Although the market has hit new highs, it has been a volatile period. This
volatility has presented many good buying opportunities, particularly within the
technology sector. At the beginning of the year, the portfolio held a large
number of mid-capitalization stocks. Initially, two factors were involved in the
decision to hold more mid-capitalization stocks: first, the valuations on many
of the larger companies were high and the earnings could not be purchased at
reasonable prices; second, the economic and political environment indicated that
the market could become more comfortable with mid-cap issues. The latter had
been lagging the market since last June and are the primary reason for the
portfolio's underperformance. Since the beginning of the year, most of the
mid-capitalization stocks that were in the portfolio have been sold. Those
assets were reallocated to large company stocks.
  Our shift to larger more established growth companies helped during the market
sell-off in March. Some of our larger technology stocks held up well and added
positive relative performance. The portfolio's holdings in retail stocks also
performed strongly. The volatility within technology stocks created buying
opportunities in quality companies that, a few weeks earlier, were not
attractively priced. Some of the technology stocks we have purchased include:
Cisco Systems, PeopleSoft, Sun Microsystems and Hewlett-Packard.
  Lately, we have been adding to the number of stocks and the number of
industries in the portfolio. The market has been volatile this year and we
believe the best strategy in this environment is a more diversified portfolio,
not only diversified by sector but also by spreading the risk across more
stocks.

MANAGEMENT SUMMARY
 
KEMPER GOVERNMENT SECURITIES PORTFOLIO
- ------------------------------------
 
  Economic growth picked up at the start of the first quarter of 1997 and
continued to gain momentum throughout March. The bond market was volatile as
investors debated the likelihood and timing of a possible Federal Reserve Board
intervention. In March, as a preemptive move aimed at slowing growth in the
economy and at maintaining a low rate of inflation, the Federal Reserve Board
did raise short-term interest rates by 0.25 percent. This hurt the markets and
caused yields to rise and securities prices to fall.
  We began preparing for the rate hike in January by shortening the
fund's duration. Duration is a measurement of a portfolio's sensitivity to
interest rates--the shorter the duration, the less sensitive the portfolio is to
interest rate changes. In addition, we sold Treasury notes in favor of GNMA
mortgages, which have shorter durations and tend to outperform Treasuries in a
rising interest rate environment. These preemptive moves lessened the impact of
the Fed's intervention on the portfolio.
  By the end of April, signs of more modest growth began to appear and
inflation remained benign. This helped fixed-income investments begin to regain
some lost ground. As a result, market yields declined again and the government
bond market performed relatively well for the remainder of the six-month period.
  As it was clear that the economy was moderating, the duration of the portfolio
was extended and its allocation to mortgages was reduced somewhat. We remain
optimistic about the government bond market and feel that the current slow
economic growth environment with relatively benign inflation should support
further gains in the market.

KEMPER INTERNATIONAL PORTFOLIO
- ------------------------------------
 
  The International Fund reached the half-year mark ahead of the Morgan Stanley
Capital International EAFE Index+. Our concentration on highly-focused,
growth-oriented companies in the European equity markets helped us achieve
consistent returns. Low inflation, low interest rates and moderate growth,
combined with the benefits the export sector experienced due to the dollar's
strength, created a very positive investment environment throughout Europe.
  We maintained a smaller exposure to Japan than the index. The holdings we had
in this market focused on globally competitive companies that do significant
exporting to other world markets and have higher than average profit margins on
unique products or services. Technology and auto companies are two industries
that met these criteria. We modestly reduced our position in Southeast Asia,
trimming our exposure across the region. The money pulled from these struggling
Asian markets was used to increase our exposure to companies in Europe and Latin
America.
  Going forward, we remain positive on the world equity markets while being
aware that they have a heightened sensitivity to U.S. interest rates. With the
exception of the UK, we do not see signs of enough inflation to lead to rate
hikes in international markets. Our weightings should continue to favor Europe.
We are moving modestly higher in Japan and intend to continue to underweight
Asia. The focus in Latin America will remain on Mexico with smaller positions in
Peru and Brazil.

MANAGEMENT SUMMARY
 
KEMPER SMALL CAP GROWTH PORTFOLIO
- ------------------------------------
 
  Small company stocks have seen a rebound in recent months. Relative to the
rest of the market small company stocks are still attractive. Their valuations
are considerably lower than those of the large company stocks driving market
returns.
  The portfolio's outperformance can be attributed to two things--technology and
consumer nondurable stocks. Throughout the year the portfolio has remained
overweighted in both sectors. The technology portion of the portfolio has
benefited from outsourcing, semiconductor and software companies. The consumer
non-durable holdings which have performed well are retail and full service
hotels.
  During the first half of the year growth stocks--particularly technology
issues--were in favor. Going forward the portfolio will likely place more
emphasis on cyclical stocks. We believe that cyclical stocks will perform well
as the economy continues to strengthen and lower interest rates begin spurring
demand. We will continue to use a "bottom-up" approach and select stocks based
on their own merits rather than focus on an entire sector. Our approach will
continue to focus on companies we believe have sustainable, predictable earnings
growth, healthy balance sheets and strong management. And finally, the companies
must be attractively valued relative to the market and their peers.

KEMPER INVESTMENT GRADE BOND PORTFOLIO
- ------------------------------------
  The six-month reporting period was somewhat volatile for investment grade
corporate bonds. Economic growth picked up at the start of the year and
continued to gain momentum throughout March. This pick-up in growth caused
investors to debate the likelihood and timing of a possible Federal Reserve
Board intervention. In March, the Federal Reserve Board (the Fed) raised
short-term interest rates by 0.25 percent. This was a preemptive move aimed at
slowing growth in the economy and at maintaining a low rate of inflation. The
rate hike hurt the bond markets and caused yields to rise and securities prices
to fall. Investment grade corporate bonds were hurt also by the simultaneous
decline in the stock market. Since then, however, the investment grade corporate
bond market has bounced back and regained much of the ground lost earlier.
  We prepared for the rate hike by managing the portfolio with a neutral to
defensive duration. Duration is a measurement of a fund's sensitivity to
interest rates--the shorter the duration, the less sensitive the portfolio is to
interest rate changes. As the Fed intervention became imminent, we shortened
duration further by increasing the level of cash and cash equivalents in the
portfolio. This helped to limit the impact of the short-term interest rate hike
in March. We began redeploying the cash reserves in May as it was clear that
inflation was under control and economic growth had moderated. Primarily, we
used the cash reserves to build our allocation to corporate bonds and
Treasuries.
  With its larger position in corporate bonds, the portfolio benefited as
investment grade corporate bonds rallied in May and June. We remain optimistic
about the corporate bond market. We feel the current slow economic growth
environment, with relatively benign inflation and a strong equity market, should
support further gains.

MANAGEMENT SUMMARY
 
KEMPER VALUE PORTFOLIO
- ------------------------------------
  The outstanding return of the market masks the volatility experienced this
year. Thus far, the returns of the market have been driven by a relatively small
number of stocks--so-called "nifty fifty" companies that are typically large,
multinational consumer product firms. These stocks usually have high price-to-
earnings ratios (P/E), meaning they are expensive relative to what they are
currently earning. This means we have been unable to invest in the stocks
driving the market because we are low P/E investors. Despite that, our stock
picking has been excellent and allowed us to perform well relative to our peers.
The top performing stocks in the portfolio have not been isolated to one sector.
We continue to hold substantial positions in financial and energy stocks. Both
of these areas continue to show strong performance and solid fundamentals.
  We are comfortable with the position of the portfolio and we believe it has
the potential to do well under most scenarios. We own very few of the "nifty
fifty" stocks. So, if the rest of the market begins to outperform these stocks,
we should do well relative to our competition because we will have bought many
of these non- "nifty fifty" stocks at lower levels. Also, should the "nifty
fifty" stocks begin to fall, their decline should affect us less since our
holdings do not typically fall into the high-priced , growth-oriented category.
While future performance can not be predicted with certainty, the portfolio will
be insulated, to an extent, by our value philosophy should the market begin to
decline, and conversely, has the potential to perform well if the market
continues to surprise on the upside.

KEMPER SMALL CAP VALUE PORTFOLIO
- ------------------------------------
 
  Small company stocks have shown momentum in June, and have begun to make up
ground against large cap stocks. Investors are still favoring the large liquid
stocks and money flowing into those stocks has driven up their prices. We feel
the new-found momentum of small company stocks is sustainable because their
price-to-earnings ratios are lower than those of large company stocks. And,
large company profits are beginning to level off as a strengthening dollar puts
pressure on earnings.
  Strong stock selection has been the key to the portfolio's outperformance this
year. For the first part of the year much of the outperformance was due to our
underweighting in technology stocks. As technology stocks rebounded at mid-year,
our stock selection has been the driving force behind the portfolio's
performance. Individual issues which have done well for us include: Electroglas,
a semi-conductor company, and Asyst Technologies, a company that makes clean
rooms in which semi-conductors are made. Scientific-Atlanta and Jones Intercable
have shown strong performance this year. Compass Bancshares has worked well in
the consumer finance area. Airborne Freight, the overnight delivery company, has
also done well this year. We will continue to concentrate on stock selection.
Our job is not to time the market but to position the portfolio for the
opportunity to perform well in both up and down markets.

KEMPER VALUE+GROWTH PORTFOLIO
- ------------------------------------
  While we tend to adhere to a "growth at the right price" philosophy, the
market lately seems to be driven by a "growth at any price" approach. Investors
have been focusing on a very concentrated group of stocks: large, multinational
companies with strong brands such as Coke and McDonald's. People seem willing to
pay any amount to own these stocks. We believe these stocks are too expensive
and, while our performance has been hindered somewhat by not owning them, we see
far more downside than upside to them at this point.
  The strategy for the year has been one of "bottom-up" stock picking rather
than trying to predict broad moves in the market. On the value side of the
portfolio we have been buying tobacco stocks. Financial stocks continue to
perform well and we have been adding to basic industries such as paper, steel,
and chemicals. Our growth stock holdings remain committed to technology which,
after some bumps along the way, have bounced back nicely. The portfolio
currently remains allocated 60% growth and 40% value stocks. The current
economic environment, moderate growth and stable interest rates, typically tends
to favor growth stocks. Until we see signs of an accelerating economy or a
threat of significantly higher interest rates, we'll likely maintain our bias
toward growth stocks.

HORIZON 10+
 
HORIZON 5 PORTFOLIOS
- ------------------------------------
 
  This year the market has been led by large capitalization domestic stocks,
although small company and international stocks have been staging a comeback
recently. The market's value has increased dramatically but so has its
volatility. When the market has declined, the portfolios' diversification has
paid off. But, because large cap stocks have significantly outperformed all
other asset classes, overall the portfolio has modestly trailed the market.
  The portfolios' performance has been led by technology and financial stocks.
Technology stocks have been volatile throughout the year but overall have been
strong performers. Financial stocks have also done well and with less volatility
than technology stocks. We have begun to increase our holdings in tobacco stocks
and basic industry which includes stocks in paper, chemicals and steel. This is
due to our expectation for a continued strong economy.
  Going forward we will begin to commit more assets to small company and
international stocks as those areas are becoming more attractive relative to
large company domestic stocks. On the bond side we will be concentrating on
further diversifying our holdings to add more government agency and corporate
bonds to the portfolios as these should provide greater income than Treasury
bonds.

KEMPER BLUE CHIP PORTFOLIO
- ------------------------------------
 
  This portfolio made its debut in May 1997. The portfolio currently holds 81
stocks but remains invested 37% in cash and equivalents. Our philosophy is one
of "bottom-up" stock selection. Rather than focus on economic conditions or
entire sectors, we tend to choose stocks based on their individual merits, and
seek those that offer above-average growth prospects, but are selling at what we
believe to be attractive prices. To do that, we set upper and lower price
targets on stocks. If a stock falls below a certain price level, normally we
buy. If it rallies above a certain price level, normally we sell. In this way,
we hope to benefit from most of the ride up, but avoid most of the ride down.
  Consumer nondurable stocks make up the largest portion of the portfolio. These
stocks are generally considered defensive stocks, since demand for them tends to
be be fairly constant. Retail and consumer stocks have been a focus within this
sector. Finance, technology and healthcare stocks are other areas where we
believe there is strong potential. Financial holdings include banks and
brokerages and we've recently increased insurance company holdings due to our
belief that consolidation within the industry may create attractive
opportunities for the consolidators.

KEMPER GLOBAL INCOME PORTFOLIO
- ------------------------------------
 
  Because Kemper Global Income Portfolio was initially offered on May 1, 1997,
this report only covers two months of activity. In May, of the 21 foreign
government markets we monitor, all but one (Australia) had positive returns in
U.S. dollar terms. The yen rebounded, appreciating significantly against the
U.S. dollar and raising yen bond performance to the top of world bond markets. A
weaker dollar boosted returns for dollar-based investors.
  In June, world bond markets were dominated by major currency moves with the
Japanese yen still in the lead followed closely by the British pound; both rose
nearly two percent against the U.S. dollar. The top performing markets in U.S.
dollar terms were Japan, the United Kingdom and Sweden while Austria and
Switzerland lagged. Prices increased across the board. Lower short-term interest
rates in countries such as Italy, New Zealand and Australia provided a further
boost to markets already supported by low inflation and moderate economic
growth.
  The best performers in U.S. dollar terms for the semiannual period were Japan
and the U.K. while Sweden and Finland rounded out the bottom.

      FUND                   as Kemper Investors Fund) is an open-end,         
                             diversified management investment company organized
                             as a business trust under the laws of     
                             Massachusetts. The Fund offers sixteen Portfolios.
                             The Fund has added the "Kemper" name to each      
                             Portfolio.

2    SIGNIFICANT             INVESTMENT VALUATION.
     ACCOUNTING POLICIES     Investments are stated at value.
                             The securities of the Portfolios (excluding the
                             Kemper Money Market Portfolio) that are traded on a
                             domestic securities exchange or securities listed
                             on the NASDAQ National Market are valued at the
                             last sale price on the exchange or market where
                             primarily traded or listed or, if there is no
                             recent sale, at the last current bid quotation.
                             Portfolio securities that are primarily traded on
                             foreign securities exchanges are generally valued
                             at the preceding closing values of such securities
                             on their respective exchanges where primarily
                             traded. A security that is listed or traded on more
                             than one exchange is valued at the quotation on the
                             exchange determined to be the primary market for
                             that security by the Board of Trustees or its
                             delegates. All other securities not so traded or
                             listed are valued at the last current bid quotation
                             if market quotations are available. Fixed income
                             securities are valued by using market quotations,
                             or independent pricing services that use prices
                             provided by market makers or estimates of market
                             values obtained from yield data relating to
                             instruments or securities with similar
                             characteristics. Equity options are valued at the
                             last sale price unless the bid price is higher or
                             the asked price is lower, in which event such bid
                             or asked price is used. 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.
                             Over-the-counter traded fixed income options are
                             valued based upon prices provided by market makers.
                             Forward foreign currency contracts and foreign
                             currencies are valued at the forward and current
                             exchange rates, respectively, prevailing on the day
                             of valuation. Other securities and assets are
                             valued at fair value as determined in good faith by
                             the Board of Trustees.
                             
 
                             The securities of the Kemper Money Market Portfolio
                             are stated at amortized cost, which approximates
                             market value. In the event that a deviation of 1/2
                             of 1% or more exists between the Portfolio's $1.00
                             per share net asset value, calculated at amortized
                             cost, and the net asset value calculated by
                             reference to market quotations, or if there is any

                             would result in a material dilution to shareholders
                             or purchasers, the Board of Trustees will promptly

                             available, the rates of exchange are determined in
                             good faith by the Board of Trustees. Income and
                             expenses and purchases and sales of investments are
                             translated into U.S. Dollars at the rates of
                             exchange prevailing on the respective dates of such
                             transactions. The Portfolios include that portion
                             of the results of operations resulting from changes
                             in foreign exchange rates with the net realized and
                             unrealized gain (loss) on investments.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date (date the order to buy or sell is
                             executed). Dividend income is recorded on the
                             ex-dividend date, except that certain dividends
                             from foreign securities are recorded as soon as the
                             information is available to the Fund. Interest
                             income is recorded on the accrual basis and
                             includes discount amortization on all fixed income
                             securities and premium amortization on
                             mortgage-backed securities and money market
                             instruments. Realized gains and losses from
                             investment transactions are reported on an
                             identified cost basis.
 
                             Several of the Portfolios may purchase securities
                             with delivery or payment to occur at a later date.
                             At the time a Portfolio enters into a commitment to
                             purchase a security, the transaction is recorded
                             and the value of the security is reflected in the
                             net asset value. The value of the security may vary
                             with market fluctuations. No interest accrues to
                             the Portfolio until payment takes place. At the
                             time the Portfolio enters into this type of
                             transaction it is required to segregate cash or
                             other liquid assets equal to the value of the
                             securities purchased. At June 30, 1997, the Kemper
                             Government Securities Portfolio had $12,099,000 of
                             purchase commitments outstanding (15% of net
                             assets) with a corresponding amount of assets
                             segregated.
 
                             EXPENSES. Expenses arising in connection with a
                             Portfolio are allocated to that Portfolio. Other
                             Fund expenses are allocated among the Portfolios in
                             proportion to their relative net assets.
 
                             FUND SHARE VALUATION. Shares of each Portfolio of
                             the Fund are offered on a continuous basis to the
                             separate accounts of participating insurance
                             companies where permitted by law. On each day the
                             New York Stock Exchange is open for trading, each
                             Portfolio determines its net asset value per share
                             (NAV) by dividing the total value of the
                             Portfolio's investments and other assets, less
                             liabilities, by the number of Portfolio shares
                             outstanding. The NAV is determined as of the
                             earlier of 3:00 p.m. Chicago time or the close of
                             the Exchange for all Portfolios, and additionally
                             at 11:00 a.m. Chicago time for the Kemper Money
                             Market Portfolio. Because of the need to obtain
                             prices as of the close of trading on various
                             exchanges throughout the world, the calculation of
                             net asset value for the International Portfolio
                             does not take place contemporaneously with the
                             determination of prices of the Fund's foreign
                             securities.
 
                             FEDERAL INCOME TAXES. Each Portfolio has complied
                             with the special provisions of the Internal Revenue
                             Code available to investment companies for the six
                             months ended June 30, 1997. The accumulated net
                             realized loss on sales of investments for federal
                             income tax purposes at June 30, 1997
 
                                                                              19

                             amounted to approximately $21,301,000 in the Kemper
                             High Yield Portfolio, $4,522,000 in the Kemper
                             Government Securities Portfolio and $2,000 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 2005.
 
                             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 will 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 ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares in all
                             Portfolios except the Kemper Money Market Portfolio
                             is credited or charged to undistributed net
                             investment income so that income per share
                             available for distribution is not affected by sales
                             or redemptions of shares.

6    FINANCIAL FUTURES       The Kemper Small Cap Value, Kemper Value+Growth,
     CONTRACTS               Kemper Horizon 20+ and Kemper Government Securities
                             Portfolios have entered into exchange traded
                             financial futures contracts in order to help
                             protect themselves from 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, 1997, the market value of assets pledged by the
                             Portfolios to cover margin requirements for open
                             futures positions were $99,000, $149,000, $25,000
                             and $706,000 for the Kemper Small Cap Value, Kemper
                             Value+Growth, Kemper Horizon 20+ and Kemper
                             Government Securities Portfolios, respectively. At
                             June 30, 1997, Kemper Government Securities
                             Portfolio also had liquid securities in its
                             portfolio in excess of the face amount of open
                             short futures contracts. At June 30, 1997, the
                             Portfolios had the following futures contracts
                             open, with expirations in September 1997:

7  FORWARD FOREIGN         In order to protect themselves against a decline in

                           the U.S. Dollar, the Kemper Total Return, Kemper
                           Growth and Kemper International Portfolios have
                           entered into forward contracts to deliver foreign
                           currency in exchange for U.S. Dollars as described
                           below. The Portfolios bear the market risk that
                           arises from changes in foreign exchange rates, and
                           accordingly, the net unrealized gain (loss) amounts
                           on these contracts are reflected in the
                           accompanying financial statements. The Portfolios
                           also bear the credit risk if the counterparty fails
                           to perform under the contract. At June 30, 1997,
                           the Portfolios had the following forward foreign
                           currency contracts outstanding with settlement
                           dates in July, 1997:

ended June 30, 1997 and the year ended December 31, 1996 were $.0123 and $.0183,
respectively. Foreign commissions usually are lower than U.S. commissions when
expressed as cents per share due to the lower per share price of many non-U.S.
securities.
