TERMS TO KNOW
 
NIFTY FIFTY EFFECT Market scenario in which the stock prices of the largest
companies of the S&P 500 rise at a greater rate than the overall market. In the
1960s and 1970s, the "Nifty Fifty" comprised a select group of 50 large,
dominant companies. Recently, the Nifty Fifty effect has been driven by
investors seeking the greater perceived security of stocks of the largest
companies.

GRAY MONDAY The name used to identify Monday, October 27, 1997. On that day,
turmoil in Southeast Asian markets triggered a one-day drop of 7 percent in the
U.S. equity market.
 
QUANTITATIVE ANALYSIS Research based on measurable factors, versus qualitative
considerations such as the character of management or employee morale. Examples
of quantitative analysis include the value of assets, the cost of capital, the
historical and projected patterns of sales, costs and profitability; and a wide

DEAR SHAREHOLDERS,
 
It's been a bumpy ride for many investors in the third quarter of 1998. Economic
and political instability in Russia, terrorist bombings and U.S. retaliation
overseas, lingering effects of the "contagion" in Asia, not to mention weak
corporate profits and political scandal in the United States were responsible
for considerable uncertainty and market volatility. A series of market dips and
drops continued to fuel 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 U.S. -- particularly Treasury bonds. 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 or
could even move lower during 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 one-time factors, including a
domestic correction in inventory levels and the General Motors strike, which has
since been resolved, as well as the long-term loss of trade with Asia.
 
  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 1998's slow corporate profit growth
and turmoil in Russia and 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
 

                                                                     3

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.
 
  Thank you for your continued support. We appreciate the opportunity to serve
your investment needs.

PORTFOLIO MANAGER. HE IS ALSO THE LEAD PORTFOLIO MANAGER OF KEMPER QUANTITATIVE
EQUITY FUND AND KEMPER VALUE+GROWTH FUND. FORTUNA RECEIVED A BACHELOR'S DEGREE
IN ECONOMICS FROM CARNEGIE MELLON UNIVERSITY AND AN M.B.A. FROM THE UNIVERSITY
OF CHICAGO.

      FORTUNA IS ASSISTED BY PORTFOLIO MANAGER KARLA GRANT, A VICE PRESIDENT OF
SCUDDER KEMPER INVESTMENTS WITH EIGHT YEARS OF INVESTMENT EXPERIENCE; AND BY
ROBERT TYMOCZKO, WHO HAS FIVE YEARS OF EXPERIENCE IN QUANTITATIVE ANALYSIS AND
ECONOMIC MODELING.

THE VIEWS EXPRESSED IN THIS REPORT REFLECT THOSE OF THE PORTFOLIO MANAGERS ONLY
THROUGH THE END OF THE PERIOD OF THE REPORT, AS STATED ON THE COVER. THE
MANAGERS' VIEWS ARE SUBJECT TO CHANGE AT ANY TIME, BASED ON MARKET AND OTHER
CONDITIONS.
 
DURING THE PAST TWELVE MONTHS, MARKET VOLATILITY HAS KEPT INVESTORS ON THEIR
TOES. LEAD PORTFOLIO MANAGER PHILIP FORTUNA AND HIS TEAM DISCUSS HOW THEY
POSITIONED KEMPER HORIZON FUND DURING THIS CHALLENGING PERIOD.
 
Q     THE PAST TWELVE MONTHS HAVE BEEN DOMINATED BY TURBULENCE. COULD YOU GIVE
US SOME INSIGHT AS TO WHY THE MARKET HAS SEEN SUCH A HIGH LEVEL OF VOLATILITY?
 
A     The past year certainly has been characterized by dramatic ups and downs.
Toward the outset of the fiscal year, currency turmoil in Asia sent global
markets into a downward spin. Asia's woes spread to the United States, as
investors wondered whether domestic companies would be able to sustain the high
level of earnings that they had enjoyed over recent years. On October 27, 1997
- -- now referred to as "Gray Monday" -- the anxiety reached a crescendo, and U.S.
equity markets dove 7 percent.
 
      However, as 1997 came to a close, we saw domestic equity markets had
rebounded quickly from the meltdown. The International Monetary Fund's bailout
plans inspired renewed confidence, as did the earnings posted by many American
firms. We entered 1998 on a brisk, positive note.

      Nonetheless, as the year progressed, we saw the tides of volatility return
repeatedly to our markets. It became clear that the economic crisis in Asia had
not been resolved fully, and the consequences of this realization hit the U.S.
market in waves. Concerns about an interest-rate hike also dogged the market
during the early portion of the year. These factors contributed to a bounty of
disappointing earnings stories, particularly among smaller-company and
technology stocks.
 
Q     HOW DID THE HORIZON PORTFOLIOS PERFORM IN THIS CHALLENGING ENVIRONMENT?
 
A     For the fiscal year ending July 31, 1998, Kemper Horizon 5 Portfolio
earned 7.74 percent, Kemper Horizon 10+ Portfolio returned 9.75 percent and
Kemper Horizon 20+ Portfolio gained 9.04 percent (Class A shares, unadjusted for
any sales charge). The S&P 500 Index, a large-cap stock index often used as a
proxy for the U.S. equity market, climbed 19.31 percent, while the small-cap
oriented Russell 2000 rose 2.31 percent. The MSCI EAFE Index, a pool of
international stocks, gained 5.75 percent; and the Lehman Brothers
Government/Corporate Bond Index returned 8.06 percent. So, the returns of the
Horizon portfolios landed among the benchmarks. This makes sense, given that the
portfolios mix the asset classes tracked by each index.
 
Q     COULD YOU TELL US MORE ABOUT HOW THE PORTFOLIOS COMBINE BONDS AND DOMESTIC
AND INTERNATIONAL STOCKS? WHAT'S THE GOAL OF THIS APPROACH?
 
A     By allocating assets between stocks and bonds, we seek to provide
shareholders with the opportunity to reap the benefits of diversification. By
investing in a variety of asset classes, we aim to offset losses from one asset
class with gains from another. Kemper Horizon 5 Portfolio, the most conservative
of the trio, holds the majority of its assets in fixed-income securities. It's
designed for investors with a short time horizon. Kemper
 

                                                                               5
<PAGE>   6
PERFORMANCE UPDATE 


Horizon 10+ Portfolio typically invests roughly 60 percent of its assets in
stocks and 40 percent in bonds. It's designed for investors with a mid-range
time frame of 10 years or more. Kemper Horizon 20+ Portfolio, the most
aggressive of the group, earmarks about 80 percent of assets to equities, and
contains the most international exposure. As its name suggests, its asset
allocation is better suited for investors with time horizons of 20 years or
more.
 
Q     HOW DID THE DIFFERENT ASSET CLASSES IMPACT PERFORMANCE?
 
A     The fund's bond stake added stability against the turbulence in the equity
market. The fixed-income allocation is quality-focused, and holds an average
credit rating of AAA. The duration of the bond portfolio is currently a mild 2.5
years. Although the fund can invest in high yield bonds, we have elected to
avoid them for now; instead we currently favor U.S. Treasuries because of their
greater stability and security and mortgage-backed securities.
 
      The fund's domestic equity exposure is divided between growth and value
stocks. Throughout the past year, we've been increasing the growth/value mix to
70/30, from 60/40. Our analysis paid off -- in the current market, growth stocks
have been rewarded more handsomely than their value counterparts. We favored
large company stocks over small company names, another decision that served the
fund in good stead, as the market turmoil punished the small-caps with a greater
vengeance.
 
Q     GIVEN THE ASIAN TURMOIL OF THE PAST YEAR, A GREAT DEAL OF INVESTOR
ATTENTION HAS TURNED TO INTERNATIONAL MARKETS. HOW DID THE INTERNATIONAL PORTION
OF THE PORTFOLIOS PERFORM?
 
A     Within the portfolios' international stake, we were also well-positioned.
In the first half of the fiscal year, we saw international holdings dampen
gains, but they've come back nicely, and have earned solid returns for the fund.
Our decision to favor Western European markets over Asian ones proved wise.
While Asia is still struggling mightily, the force of strengthening economies
and the potential benefits of unification have propelled Europe. France, Italy,
Germany and the United Kingdom count among the markets that garnered good
performance for the portfolios.
 
Q     WHAT WERE THE FACTORS THAT CAUSED THE PORTFOLIOS TO LAG DURING THE ANNUAL
PERIOD?
 
A     The volatility of the overall market has made many investors nervous.
Rather than keeping focused on fundamentals, many investors rushed headlong to
the perceived safety offered by the largest blue chip names. Much of the overall
market performance has thus been driven by a handful of the largest companies --
the biggest names of the S&P 500 Index. This "flight to enormity" has caused the
prices of this small group of stocks to rise far above price levels which we
feel are reasonable and sustainable. Therefore, our valuation discipline
compelled us to steer clear of the highest-priced names, at the expense of some
short-term gains. We would caution investors against being lulled into an
unreasonable sense of security, just because they may own the mega-cap names.
Their valuations are too high, regardless of the company's size.
 
      Our exposure to certain sectors also caused the portfolios to lag. In the
first half of the fiscal year, the fund's overweighting in technology hurt
returns, as these stocks felt the brunt of the turmoil in Asia. We have seen
many of our technology names rebound, since, however. Throughout the year,
tobacco exposure also clipped gains, as regulatory concerns plagued that
industry. Our exposure to energy also hindered performance, as the fears
stemming out of Asian supply-and-demand issues got the better of many energy
stocks. Nevertheless, we believe a number of stocks in these two industries
continue to offer investors significant upside potential at very attractive
valuations.
 
Q     HOW DO YOU FIND STOCKS IN THIS CHOPPY MARKET CLIMATE?
 
A     We use the same criteria, regardless of market conditions. We seek out
stocks that boast sound valuations. To keep from getting swept away by the
current of an emotional market, we rely heavily on quantitative analysis. Before
making a judgement about whether or not to buy a stock, we scrutinize the
company's operations and fundamentals. We evaluate the stock price relative to
many factors, including book value, cash flow and earnings growth. We place this
information within a larger economic framework, weighing the possible impact of
inflation, economic growth and interest rates.
 
Q     GIVEN THE CHALLENGES THAT THE MARKET HAS POSED OVER THE PAST TWELVE

quantitative focus. The recent turbulence of the market reinforces our
conviction 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 market opportunity. We've always relied on quantitative
measures, however, in the future we will be employing more sophisticated
quantitative models to select securities for the fund. Different models will be
used to select domestic growth stocks, domestic value stocks, and international
stocks. These models focus on the same sort of factors (valuations, earnings
growth, and price momentum) that have historically driven our stock-selection
process.
 
      We believe that this move will allow us to take the quantitative bent of
the fund to the next level. Scudder Kemper Investments has built a strong staff
of quantitative managers and analysts, and we're excited to leverage this
expertise to an even greater degree. The models we're using have been tested
extensively and used in institutional, high net worth and other fund accounts.
Moreover, we've brought on new portfolio managers, Robert Tymoczko and Karla
Grant. (Co-Lead Portfolio Manager William Knapp left the fund's management team
at the end of July 1998).
 
Q     DO YOU EXPECT THE MARKET TURMOIL TO ABATE ANY TIME SOON?
 
A     When it comes to investing, volatility is par for the course. Shorter-term
ups and downs are unavoidable. We can't predict when the market will fully
digest the Asian crisis and return to a more rational approach to valuing
stocks. We're prepared to see more volatility, and have gravitated toward stocks
that we believe are more resilient to the market's downward turns. However, we
believe that many factors support a positive long-term market forecast: the
economy is slowing, inflation has been kept in check, and interest rates remain
low. We hold that a disciplined approach to investing, paired with an emphasis
on diversification, is still a sound route for investors to follow.

 *    Average annual total return and total return measure net investment income
      and capital gain or loss from portfolio investments over the periods
      specified, assuming reinvestment of dividends and, where indicated,
      adjustment for the maximum sales charge.  The maximum sales charge for
      Class A Shares is 5.75%, for Class B Shares, the maximum contingent
      deferred sales charge is  4%. Class C Shares have no sales adjustment,
      but redemptions within one year of purchase may be subject to a contingent
      deferred sales charge of 1%. Share classes invest in the same underlying
      portfolio. Average annual return reflects annualized change. During the
      periods noted, securities prices fluctuated. For additional information,
      see the Prospectus and Statement of Additional Information and the
      Financial Highlights at the end of this report.
 
 (1)  Performance includes reinvestment of dividends and adjustment for the
      maximum sales charge for Class A  Shares and the contingent deferred sales
      charge in effect at the end of the period for Class B Shares. Each
      portfolio is compared to the Standard & Poor's 500 Stock Index (S&P 500),
      Lehman Brothers Gov't/Corp. Bond Index and a blend of the S&P 500 and the
      Lehman Brothers Gov't/ Corp. Bond Index. Kemper Horizon 20+ Portfolio is
      compared with a blend of 80 percent S&P 500 and 20 percent Lehman Brothers
      Gov't/Corp. Kemper Horizon 10+ Portfolio is compared with a blend of 60
      percent S&P 500 and 40 percent Lehman Brothers Gov't/Corp. Kemper Horizon
      5 Portfolio is compared with a blend of 40 percent S&P 500 and 60 percent
      Lehman Brothers Gov't/Corp. In comparing Kemper Horizon Fund to the
      blended indices, you should note that the fund's performance reflects the
      maximum sales charge, while no such charges are reflected in the
      performance of the indices.

*    Average annual total return and total return measure net investment
     income and capital gain or loss from portfolio investments over the periods
     specified, assuming reinvestment of dividends and, where indicated, 
     adjustment for the maximum sales charge. The maximum sales charge for Class
     A Shares is 5.75%, for Class B Shares, the maximum contingent deferred 
     sales charge is 4%. Class C Shares have no sales adjustment, but 
     redemptions within one year of purchase may be subject to a contingent 
     deferred sales charge of 1%. Share classes invest in the same underlying 
     portfolio. Average annual return reflects annualized change. During the 
     periods noted, securities prices fluctuated. For additional information, 
     see the Prospectus and Statement of Additional Information and the 
     Financial Highlights at the end of this report.
 
(1)  Performance includes reinvestment of dividends and adjustment for the
     maximum sales charge for Class A Shares and the contingent deferred sales
     charge in effect at the end of the period for Class B Shares. Each
     portfolio is compared to the Standard & Poor's 500 Index (S&P 500), Lehman
     Brothers Gov't/Corp. Bond Index and a blend of the S&P 500 and the Lehman
     Brothers Gov't/Corp. Bond Index. Kemper Horizon 20+ Portfolio is compared
     with a blend of 80 percent S&P 500 and 20 percent Lehman Brothers
     Gov't/Corp. Kemper Horizon 10+ Portfolio is compared with a blend of 60
     percent S&P 500 and 40 percent Lehman Brothers Gov't/Corp. Kemper Horizon 5
     Portfolio is compared with a blend of 40 percent S&P 500 and 60 percent
     Lehman Brothers Gov't/Corp. In comparing Kemper Horizon Fund to the blended
     indices, you should note that the fund's performance reflects the maximum
     sales charge, while no such charges are reflected in the performance of the
     indices.

 *    Average annual total return and total return measure net investment income
      and capital gain or loss from portfolio investments over the periods      
      specified, assuming reinvestment of dividends and, where indicated,
      adjustment for the maximum sales charge. The maximum sales charge for
      Class A Shares is 5.75%, for Class B Shares, the maximum contingent
      deferred sales charge is 4%. Class C Shares have no sales adjustment, but
      redemptions within one year of purchase may be subject to a contingent
      deferred sales charge of 1%. Share classes invest in the same underlying
      portfolio. Average annual return reflects annualized change. During the
      periods noted, securities prices fluctuated. For additional information,
      see the Prospectus and Statement of Additional Information and the
      Financial Highlights at the end of this report.
 
 (1)  Performance includes reinvestment of dividends and adjustment for the
      maximum sales charge for Class A Shares and the contingent deferred sales
      charge in effect at the end of the period for Class B Shares. Each
      portfolio is compared to the Standard & Poor's 500 Index (S&P 500), Lehman
      Brothers Gov't/Corp. Bond Index and a blend of the S&P 500 and the Lehman
      Brothers Gov't./Corp. Bond Index. Kemper Horizon 20+ Portfolio is compared
      with a blend of 80 percent S&P 500 and 20 percent Lehman Brothers
      Gov't/Corp. Kemper Horizon 10+ Portfolio is compared with a blend of 60
      percent S&P 500 and 40 percent Lehman Brothers Gov't/Corp. Kemper Horizon
      5 Portfolio is compared with a blend of 40 percent S&P 500 and 60 percent
      Lehman Brothers Gov't/ Corp. In comparing Kemper Horizon Fund to the
      blended indices, you should note that the fund's performance reflects the
      maximum sales charge, while no such charges are reflected in the
      performance of the indices.

REPORT OF INDEPENDENT AUDITORS 

THE BOARD OF TRUSTEES AND SHAREHOLDERS
 
KEMPER HORIZON FUND
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of Kemper Horizon 20+ Portfolio, Kemper
Horizon 10+ Portfolio and Kemper Horizon 5 Portfolio, comprising Kemper Horizon
Fund (the Fund), as of July 31, 1998, the related statements of operations for
the year then ended and the statement of changes in net assets for each of the
two years in the period then ended and the financial highlights for each of the
fiscal periods since 1996. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of investments owned as of July
31, 1998, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the portfolios comprising Kemper Horizon Fund at July 31, 1998, the results
of their operations, the changes in their net assets and the financial
highlights for the periods referred to above in conformity with generally
accepted accounting principles.

1    DESCRIPTION OF THE
     FUND                    Kemper Horizon Fund (the "Fund") is an open-end
                             diversified management investment company organized
                             as a business trust under the laws of
                             Massachusetts. The Fund consists of three
                             investment portfolios ("Portfolios") designed for
                             investors with different investment objectives. The
                             three Portfolios are Kemper Horizon 20+, Kemper
                             Horizon 10+ and Kemper Horizon 5. Each Portfolio
                             currently offers four classes of shares. Class A
                             shares are sold to investors subject to an initial
                             sales charge. Class B shares are sold without an
                             initial sales charge but are subject to higher
                             ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions. Class B shares automatically
                             convert to Class A shares six years after issuance.
                             Class C shares are sold without an initial sales
                             charge but are subject to higher ongoing expenses
                             than Class A shares and a contingent deferred sales
                             charge payable upon certain redemptions within one
                             year of purchase. Class C shares do not convert
                             into another class. Class I shares are offered to a
                             limited group of investors, are not subject to
                             initial or contingent deferred sales charges and
                             have lower ongoing expenses than other classes.
                             Differences in class expenses will result in the
                             payment of different per share income dividends by
                             class. All shares of each Portfolio have equal
                             rights with respect to voting, dividends and
                             assets, subject to class specific preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Portfolio securities 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. 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.
                             Forward foreign currency contracts are valued at
                             the forward rates 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.
 
                             FOREIGN CURRENCY TRANSLATION. The books and records
                             of the Portfolios 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.
 
                                                                              33

                             INVESTMENT TRANSACTIONS AND INVESTMENT
                             INCOME. Investment transactions are accounted for
                             on the trade date. Dividend income is recorded on
                             the ex-dividend date, and 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.
 
                             EXPENSES. Expenses arising in connection with a
                             specific Portfolio are allocated to that Portfolio.
                             Other Fund expenses are allocated among the
                             Portfolios in proportion to their relative net
                             assets.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the close of the Exchange. The net
                             asset value per share is determined separately for
                             each class by dividing the Portfolio's net assets
                             attributable to that class by the number of shares
                             of the class outstanding.
 
                             FEDERAL INCOME TAXES. Each Portfolio's policy is to
                             comply with the requirements of the Internal
                             Revenue Code, as amended, which are applicable to
                             regulated investment companies, and to distribute
                             all of its taxable income to its shareholders.
                             Accordingly, each Portfolio paid no federal income
                             taxes and no federal income tax provision was
                             required.
 
                             DIVIDENDS TO SHAREHOLDERS. Each Portfolio intends
                             to pay dividends of net investment income as
                             follows: annually for the Kemper Horizon 20+,
                             semiannually for the Kemper Horizon 10+, and
                             quarterly for the Kemper Horizon 5. Each Portfolio
                             will pay any net realized capital gains at least
                             annually. Dividends are recorded on the ex-dividend
                             date. Dividends are determined in accordance with
                             income tax principles which may treat certain
                             transactions differently from generally accepted
                             accounting principles.
 
                             EQUALIZATION ACCOUNTING. Prior to August 1, 1997,
                             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 portion of the proceeds from sales and
                             the cost of redemptions of fund shares to
                             undistributed net investment income. As of August
                             1, 1997, the Portfolios discontinued using
                             equalization. This change has no effect on the
                             Portfolios' net assets, net asset value per share
                             or distributions to shareholders. Discontinuing the
                             use of equalization accounting will result in
                             simpler financial statements. The cumulative effect
                             of the discontinuance of equalization accounting
                             was to decrease undistributed net investment income
                             and increase paid-in-capital previously reported
                             through July 31, 1997 by the following amounts (in
                             thousands):

NOTES TO FINANCIAL STATEMENTS

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

6    FINANCIAL FUTURES        The Portfolios have entered into exchange traded
     CONTRACTS                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 July 31, 1998, the market value of assets
                              pledged by the Portfolios to cover margin
                              requirements for open futures positions was
                              $35,000 for Kemper Horizon 20+, $75,000 for Kemper
                              Horizon 10+ and $103,000 for Kemper Horizon 5. The
                              Portfolios also have liquid assets in their
                              portfolios in excess of the face amount of open

FINANCIAL HIGHLIGHTS

 NOTES TO FINANCIAL HIGHLIGHTS FOR ALL PORTFOLIOS:

Total returns do not reflect the effect of any sales charges.
 
Per share data for the period ended July 31, 1996 was determined based on
average shares outstanding.
 
For the period ended July 31, 1996, the investment manager agreed to reduce its
management fee and absorb certain operating expenses of the Portfolios. If these
expense waivers had not been in effect, the expense ratio of each share class
would have increased by .06% of average net assets for Horizon 20+, .04% for
Horizon 10+ and .05% for Horizon 5. There would have been a corresponding
decrease in the net investment income ratio for the period. The waivers were
discontinued on August 1, 1996.
