SUMMARY
 
INVESTMENT OBJECTIVES.  Cash Account Trust (the "Fund") is an open-end
diversified management investment company. The Fund currently offers a choice of
three investment portfolios ("Portfolios"). Each Portfolio invests in a
portfolio of high quality short-term money market instruments consistent with
its specific objective. The Money Market Portfolio seeks maximum current income
to the extent consistent with stability of capital from a portfolio primarily of
commercial paper and bank obligations. The Government Securities Portfolio seeks
maximum current income to the extent consistent with stability of capital from a
portfolio of obligations issued or guaranteed by the U.S. Government, its
agencies or instrumentalities. The Tax-Exempt Portfolio seeks maximum current
income that is exempt from federal income taxes to the extent consistent with
stability of capital from a portfolio of municipal securities. Each Portfolio
may use a variety of investment techniques, including the purchase of repurchase
agreements and variable rate securities. Each Portfolio seeks to maintain a net
asset value of $1.00 per share. There is no assurance that the objective of any
Portfolio will be achieved or that any Portfolio will be able to maintain a net
asset value of $1.00 per share. See "Investment Objectives, Policies and Risk
Factors."
 
   
INVESTMENT MANAGER AND SHAREHOLDER SERVICES.  Zurich Kemper Investments, Inc.
("ZKI") is the investment manager for the Fund and provides the Fund with
continuous professional investment supervision. ZKI is paid an annual investment
management fee, payable monthly, on a graduated basis ranging from .22% of the
first $500 million of combined average daily net assets of all Portfolios of the
Fund to .15% of the combined average daily net assets of all Portfolios of the
Fund over $3 billion. Kemper Distributors, Inc. ("KDI"), an affiliate of ZKI, is
the primary administrator, distributor and principal underwriter of the Fund
and, as such, provides information and services for existing and potential
shareholders and acts as agent of the Fund in the sale of its shares. KDI
receives a distribution services fee, payable monthly, at an annual rate of .60%
of average daily net assets of the Money Market and Government Securities
Portfolios and .50% of average daily net assets of the Tax-Exempt Portfolio. As
distributor, KDI normally pays financial services firms that provide cash
management and other services for their customers at a maximum annual rate of
 .60% of average daily net assets of those accounts in the Money Market and
Government Securities Portfolios that they service and .50% of average daily net
assets of those accounts in the Tax-Exempt Portfolio that they maintain and
service. See "Investment Manager and Shareholder Services."
    
 
PURCHASES AND REDEMPTIONS.  Shares of each Portfolio are available at net asset
value through selected financial services firms. The minimum initial investment
for each Portfolio is $1,000 and the minimum subsequent investment is $100. See
"Purchase of Shares." Shares may be redeemed at the net asset value next
determined after receipt by the Fund's Shareholder Service Agent of a request to
redeem in proper form. Shares may be redeemed by written request or by using one
of the Fund's expedited redemption procedures. See "Redemption of Shares."
 
DIVIDENDS. Dividends are declared daily and paid monthly. Dividends are
automatically reinvested in additional shares of the same Portfolio, unless the
shareholder makes a different election. See "Dividends and Taxes."
 
GENERAL INFORMATION AND CAPITAL.  The Fund is organized as a business trust
under the laws of Massachusetts and may issue an unlimited number of shares of
beneficial interest. Shares are fully paid and nonassessable when issued, are
transferable without restriction and have no preemptive or conversion rights.
The Fund is not required to hold annual shareholder meetings; but will hold
special meetings as required or deemed desirable for such purposes as electing
trustees, changing fundamental policies or approving an investment management
agreement. See "Capital Structure."

</TABLE>
 
The purpose of the preceding table is to assist investors in understanding the
various costs and expenses that an investor in the Fund will bear directly or
indirectly. As discussed more fully under "Investment Manager and Shareholder
Services," the Fund's investment manager has agreed to temporarily waive its
management fee and reimburse or pay operating expenses of a Portfolio to the
extent, if any, that such expenses as defined, exceed the following percentages
of average daily net assets of the Portfolios: Money Market Portfolio (1.00%),
Government Securities Portfolio (.90%) and Tax-Exempt Portfolio (.80%). Without
such waiver and reimbursement during the fiscal year ended April 30, 1996,
"Management Fees" for the Money Market Portfolio, Government Securities
Portfolio and Tax-Exempt Portfolio would have been .22%, .22% and .22%,
respectively, and "Total Operating Expenses" would have been 1.05%, 1.06% and
 .98%, respectively. In addition, from time to time, ZKI may voluntarily waive
fees or absorb certain additional operating expenses of the Portfolios. "Other
Expenses" does not reflect the effect of this additional expense absorption. The
Example assumes a 5% annual rate of return pursuant to requirements of the
Securities and Exchange Commission. This hypothetical rate of return is not
intended to be representative of past or future performance of any Portfolio of
the Fund. THE EXAMPLE SHOULD NOT BE CONSIDERED TO BE A REPRESENTATION OF PAST OR
FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESSER THAN THOSE SHOWN.

NOTES:
a. The Money Market Portfolio's total returns for the years ended April 30, 1996
   and 1995 include the effect of a capital contribution from the investment
   manager. Without the capital contribution, the total returns would have been
   4.80% and 4.16%, respectively.
b. ZKI has agreed to temporarily waive its management fee and reimburse or pay
   certain operating expenses to the extent necessary to limit expenses to
   specific levels. The Other Ratios to Average Net Assets are computed without
   this waiver and expense absorption. Ratios have been determined on an
   annualized basis. Total return is not annualized.
 
INVESTMENT OBJECTIVES, POLICIES AND RISK FACTORS
 
The Fund is a money market mutual fund designed to provide its shareholders with
professional management of short-term investment dollars. It is designed for
investors who seek maximum current income consistent with stability of capital.
The Fund pools individual and institutional investors' money that it uses to buy
high quality money market instruments. The Fund is a series investment company
that is able to provide investors with a choice of separate investment
portfolios ("Portfolios"). It currently offers three investment Portfolios: the
Money Market Portfolio, the Government Securities Portfolio and the Tax- Exempt
Portfolio. Because each Portfolio combines its
 
                                        3
<PAGE>   5
 
shareholders' money, it can buy and sell large blocks of securities, which
reduces transaction costs and maximizes yields. The Fund is managed by
investment professionals who analyze market trends to take advantage of changing
conditions and who seek to minimize risk by diversifying each Portfolio's
investments. A Portfolio's investments are subject to price fluctuations
resulting from rising or declining interest rates and are subject to the ability
of the issuers of such investments to make payment at maturity. However, because
of their short maturities, liquidity and high quality ratings, high quality
money market instruments, such as those in which the Fund invests, are generally
considered to be among the safest available. Thus, the Fund is designed for
investors who want to avoid the fluctuations of principal commonly associated
with equity or long-term bond investments. There can be no guarantee that a
Portfolio will achieve its objective or that it will maintain a net asset value
of $1.00 per share.
 
MONEY MARKET PORTFOLIO. The Money Market Portfolio seeks maximum current income
consistent with stability of capital. The Portfolio pursues its objective by
investing exclusively in the following types of U.S. Dollar-denominated money
market instruments that mature in 12 months or less:
 
1. Obligations of, or guaranteed by, the U.S. or Canadian governments, their
agencies or instrumentalities.
 
2. Bank certificates of deposit, time deposits or bankers' acceptances of U.S.
banks (including their foreign branches) and Canadian chartered banks having
total assets in excess of $1 billion.
 
3. Bank certificates of deposit, time deposits or bankers' acceptances of
foreign banks (including their U.S. and foreign branches) having total assets in
excess of $10 billion.
 
4. Commercial paper, notes, bonds, debentures, participation certificates or
other debt obligations that (i) are rated high quality by Moody's Investors
Service, Inc. ("Moody's"), Standard & Poor's Corporation ("S&P"), or Duff &
Phelps, Inc. ("Duff"); or (ii) if unrated, are determined to be at least equal
in quality to one or more of the above ratings in the discretion of the Fund's
investment manager. Currently, only obligations in the top two categories are
considered to be rated high quality. The two highest rating categories of
Moody's, S&P and Duff for commercial paper are Prime-1 and Prime-2, A-1 and A-2
and Duff 1 and Duff 2, respectively. For other debt obligations, the two highest
rating categories for such services are Aaa and Aa, AAA and AA and AAA and AA,
respectively. For a description of these ratings, see "Appendix--Ratings of
Investments" in the Statement of Additional Information.
 
5. Repurchase agreements of obligations that are suitable for investment under
the categories set forth above. Repurchase agreements are discussed below.
 
In addition, the Portfolio limits its investments to securities that meet the
quality and diversification requirements of Rule 2a-7 under the Investment
Company Act of 1940. See "Net Asset Value."
 
The Money Market Portfolio will normally invest at least 25% of its assets in
obligations issued by banks; provided, however, the Portfolio may in the
discretion of the Fund's investment manager temporarily invest less than 25% of
its assets in such obligations whenever the Portfolio assumes a defensive
posture. Investments by the Money Market Portfolio in Eurodollar certificates of
deposit issued by London branches of U.S. banks, or obligations issued by
foreign entities, including foreign banks, involve risks that are different from
investments in securities of domestic branches of U.S. banks. These risks may
include future unfavorable political and economic developments, possible
withholding taxes on interest payments, seizure of foreign deposits, currency
controls, interest limitations or other governmental restrictions that might
affect payment of principal or interest. The market for such obligations may be
less liquid and, at times, more volatile than for securities of domestic
branches of U.S. banks. Additionally, there may be less public information
available about foreign banks and their branches. The profitability of the
banking industry is dependent largely upon the availability and cost of funds
for the purpose of financing lending operations under prevailing money market
conditions. General economic conditions as well as exposure to credit losses
arising from possible financial difficulties of borrowers play an important part
in banking operations. As a result of Federal and state laws and regulations,
domestic banks are, among other things, required to maintain specified levels of
reserves, limited in the amounts they can loan to a single borrower and subject
to other regulations designed to promote financial soundness. However, not all
such laws and regulations apply to the foreign branches of domestic banks.
Foreign branches of foreign banks are not
 
                                        4
<PAGE>   6
 
regulated by U.S. banking authorities, and generally are not bound by
accounting, auditing and financial reporting standards comparable to U.S. banks.
Bank obligations held by the Portfolio do not benefit materially from insurance
from the Federal Deposit Insurance Corporation.
 
The Money Market Portfolio may invest in commercial paper issued by major
corporations under the Securities Act of 1933 in reliance on the exemption from
registration afforded by Section 3(a)(3) thereof. Such commercial paper may be
issued only to finance current transactions and must mature in nine months or
less. Trading of such commercial paper is conducted primarily by institutional
investors through investment dealers and individual investor participation in
the commercial paper market is very limited. The Portfolio also may invest in
commercial paper issued in reliance on the so-called "private placement"
exemption from registration that is afforded by Section 4(2) of the Securities
Act of 1933 ("Section 4(2) paper"). Section 4(2) paper is restricted as to
disposition under the federal securities laws, and generally is sold to
institutional investors such as the Portfolio who agree that they are purchasing
the paper for investment and not with a view to public distribution. Any resale
by the purchaser must be in an exempt transaction. Section 4(2) paper normally
is resold to other institutional investors like the Portfolio through or with
the assistance of the issuer or investment dealers who make a market in the
Section 4(2) paper, thus providing liquidity. The Fund's investment manager
considers the legally restricted but readily saleable Section 4(2) paper to be
liquid; however, pursuant to procedures approved by the Board of Trustees of the
Fund, if a particular investment in Section 4(2) paper is not determined to be
liquid, that investment will be included within the 10% limitation on illiquid
securities discussed under "The Fund" below. The Fund's investment manager
monitors the liquidity of the Portfolio's investments in Section 4(2) paper on a
continuous basis.
 
The Money Market Portfolio may invest in high quality participation certificates
("certificates") representing undivided interests in trusts that hold a
portfolio of receivables from consumer and commercial credit transactions, such
as transactions involving consumer revolving credit card accounts or commercial
revolving credit loan facilities. The receivables would include amounts charged
for goods and services, finance charges, late charges and other related fees and
charges. Interest payable on the certificates may be fixed or may be adjusted
periodically or "float" continuously according to a formula based upon an
objective standard such as the 30-day commercial paper rate. See "The Fund"
below for a discussion of "Variable Rate Securities." A trust may have the
benefit of a letter of credit from a bank at a level established to satisfy
rating agencies as to the credit quality of the assets supporting the payment of
principal and interest on the certificates. Payments of principal and interest
on the certificates would be dependent upon the underlying receivables in the
trust and may be guaranteed under a letter of credit to the extent of such
credit. The quality rating by a rating service of an issue of certificates is
based primarily upon the value of the receivables held by the trust and the
credit rating of the issuer of any letter of credit and of any other guarantor
providing credit support to the trust. The Fund's investment manager considers
these factors as well as others, such as any quality ratings issued by the
rating services identified above, in reviewing the credit risk presented by a
certificate and in determining whether the certificate is appropriate for
investment by the Portfolio. Collection of receivables in the trust may be
affected by various social, legal and economic factors affecting the use of
credit and repayment patterns, such as changes in consumer protection laws, the
rate of inflation, unemployment levels and relative interest rates. It is
anticipated that for most publicly offered certificates there will be a liquid
secondary market or there may be demand features enabling the Fund to readily
sell its certificates prior to maturity to the issuer or a third party. While
the Portfolio may invest without limit in certificates, it is currently
anticipated that such investments will not exceed 25% of the Portfolio's assets.
 
GOVERNMENT SECURITIES PORTFOLIO. The Government Securities Portfolio seeks
maximum current income consistent with stability of capital. The Portfolio
pursues its objective by investing exclusively in U.S. Treasury bills, notes,
bonds and other obligations issued or guaranteed by the U.S. Government, its
agencies or instrumentalities and repurchase agreements of such obligations. All
securities purchased mature in 12 months or less. Some securities issued by U.S.
Government agencies or instrumentalities are supported only by the credit of the
agency or instrumentality, such as those issued by the Federal Home Loan Bank,
and others have an additional line of credit with the U.S. Treasury, such as
those issued by the Federal National Mortgage Association, Farm Credit System
 
                                        5
<PAGE>   7
 
and Student Loan Marketing Association. Short-term U.S. Government obligations
generally are considered to be the safest short-term investment. The U.S.
Government guarantee of the securities owned by the Portfolio, however, does not
guarantee the net asset value of its shares, which the Fund seeks to maintain at
$1.00 per share. Also, with respect to securities supported only by the credit
of the issuing agency or instrumentality or by an additional line of credit with
the U.S. Treasury, there is no guarantee that the U.S. Government will provide
support to such agencies or instrumentalities and such securities may involve
risk of loss of principal and interest. Repurchase agreements are discussed
below.
 
TAX-EXEMPT PORTFOLIO. The Tax-Exempt Portfolio seeks maximum current income that
is exempt from Federal income taxes to the extent consistent with stability of
capital. The Portfolio pursues its objective primarily through a professionally
managed, diversified portfolio of short-term high quality tax-exempt municipal
obligations. Under normal market conditions at least 80% of the Portfolio's
total assets will, as a fundamental policy, be invested in obligations issued by
or on behalf of states, territories and possessions of the United States and the
District of Columbia and their political subdivisions, agencies and
instrumentalities, the income from which is exempt from Federal income tax
("Municipal Securities"). In compliance with the position of the staff of the
Securities and Exchange Commission, the Fund does not consider "private
activity" bonds as described in "Dividends and Taxes--Tax-Exempt Portfolio" to
be Municipal Securities for purposes of the 80% limitation. This is a
fundamental policy so long as the staff maintains its position, after which it
would become non-fundamental.
 
Dividends representing net interest income received by the Tax-Exempt Portfolio
on Municipal Securities will be exempt from federal income tax when distributed
to the Portfolio's shareholders. Such dividend income may be subject to state
and local taxes. See "Dividends and Taxes--Tax-Exempt Portfolio." The
Portfolio's assets will consist of Municipal Securities, taxable temporary
investments as described below and cash. The Portfolio considers short-term
Municipal Securities to be those that mature in one year or less.
 
The Tax-Exempt Portfolio will invest only in Municipal Securities that at the
time of purchase: (a) are rated within the two highest-ratings for Municipal
Securities (Aaa or Aa) assigned by Moody's or (AAA or AA) assigned by S&P; (b)
are guaranteed or insured by the U.S. Government as to the payment of principal
and interest; (c) are fully collateralized by an escrow of U.S. Government
securities acceptable to the Fund's investment manager; (d) have at the time of
purchase Moody's short-term Municipal Securities rating of MIG-2 or higher or a
municipal commercial paper rating of P-2 or higher, or S&P's municipal
commercial paper rating of A-2 or higher; (e) are unrated, if longer term
Municipal Securities of that issuer are rated within the two highest rating
categories by Moody's or S&P; or (f) are determined to be at least equal in
quality to one or more of the above ratings in the discretion of the Fund's
investment manager. In addition, the Portfolio limits its investments to
securities that meet the quality requirements of Rule 2a-7 under the Investment
Company Act of 1940. See "Net Asset Value."
 
Municipal Securities generally are classified as "general obligation" or
"revenue" issues. General obligation bonds are secured by the issuer's pledge of
its full credit and taxing power for the payment of principal and interest.
Revenue bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special excise tax or other specific revenue source such as the user of the
facility being financed. Industrial development bonds held by the Fund are in
most cases revenue bonds and are not payable from the unrestricted revenues of
the issuer. Among other types of instruments, the Portfolio may purchase
tax-exempt commercial paper, warrants and short-term municipal notes such as tax
anticipation notes, bond anticipation notes, revenue anticipation notes,
construction loan notes and other forms of short-term loans. Such notes are
issued with a short-term maturity in anticipation of the receipt of tax
payments, the proceeds of bond placements or other revenues. A more detailed
discussion of Municipal Securities and the Moody's and S&P ratings outlined
above is contained in the Statement of Additional Information. As indicated
under "Dividends and Taxes--Tax-Exempt Portfolio," the Portfolio may invest in
short-term "private activity" bonds.
 
                                        6
<PAGE>   8
 
The Tax-Exempt Portfolio may purchase securities that provide for the right to
resell them to an issuer, bank or dealer at an agreed upon price or yield within
a specified period prior to the maturity date of such securities. Such a right
to resell is referred to as a "Standby Commitment." Securities may cost more
with Standby Commitments than without them. Standby Commitments will be entered
into solely to facilitate portfolio liquidity. A Standby Commitment may be
exercised before the maturity date of the related Municipal Security if the
Fund's investment adviser revises its evaluation of the creditworthiness of the
underlying security or of the entity issuing the Standby Commitment. The
Portfolio's policy is to enter into Standby Commitments only with issuers, banks
or dealers that are determined by the Fund's investment manager to present
minimal credit risks. If an issuer, bank or dealer should default on its
obligation to repurchase an underlying security, the Portfolio might be unable
to recover all or a portion of any loss sustained from having to sell the
security elsewhere.
 
The Tax-Exempt Portfolio may purchase high quality Certificates of Participation
in trusts that hold Municipal Securities. A Certificate of Participation gives
the Portfolio an undivided interest in the Municipal Security in the proportion
that the Portfolio's interest bears to the total principal amount of the
Municipal Security. These Certificates of Participation may be variable rate or
fixed rate with remaining maturities of one year or less. A Certificate of
Participation may be backed by an irrevocable letter of credit or guarantee of a
financial institution that satisfies rating agencies as to the credit quality of
the Municipal Security supporting the payment of principal and interest on the
Certificate of Participation. Payments of principal and interest would be
dependent upon the underlying Municipal Security and may be guaranteed under a
letter of credit to the extent of such credit. The quality rating by a rating
service of an issue of Certificates of Participation is based primarily upon the
rating of the Municipal Security held by the trust and the credit rating of the
issuer of any letter of credit and of any other guarantor providing credit
support to the issue. The Fund's investment manager considers these factors as
well as others, such as any quality ratings issued by the rating services
identified above, in reviewing the credit risk presented by a Certificate of
Participation and in determining whether the Certificate of Participation is
appropriate for investment by the Portfolio. It is anticipated by the Fund's
investment manager that, for most publicly offered Certificates of
Participation, there will be a liquid secondary market or there may be demand
features enabling the Portfolio to readily sell its Certificates of
Participation prior to maturity to the issuer or a third party. As to those
instruments with demand features, the Portfolio intends to exercise its right to
demand payment from the issuer of the demand feature only upon a default under
the terms of the Municipal Security, as needed to provide liquidity to meet
redemptions, or to maintain a high quality investment portfolio.
 
The Tax-Exempt Portfolio may purchase and sell Municipal Securities on a
when-issued or delayed delivery basis. A when-issued or delayed delivery
transaction arises when securities are bought or sold for future payment and
delivery to secure what is considered to be an advantageous price and yield to
the Portfolio at the time it enters into the transaction. In determining the
maturity of portfolio securities purchased on a when-issued or delayed delivery
basis, the Portfolio will consider them to have been purchased on the date when
it committed itself to the purchase.
 
A security purchased on a when-issued basis, like all securities held by the
Tax-Exempt Portfolio, is subject to changes in market value based upon changes
in the level of interest rates and investors' perceptions of the
creditworthiness of the issuer. Generally such securities will appreciate in
value when interest rates decline and decrease in value when interest rates
rise. Therefore if, in order to achieve higher interest income, the Portfolio
remains substantially fully invested at the same time that it has purchased
securities on a when-issued basis, there will be a greater possibility that the
market value of the Portfolio's assets will vary from $1.00 per share because
the value of a when-issued security is subject to market fluctuation and no
interest accrues to the purchaser prior to settlement of the transaction. See
"Net Asset Value."
 
The Portfolio will only make commitments to purchase Municipal Securities on a
when-issued or delayed delivery basis with the intention of actually acquiring
the securities, but the Portfolio reserves the right to sell these securities
before the settlement date if deemed advisable. The sale of these securities may
result in the realization of gains that are not exempt from federal income tax.
 
                                        7
<PAGE>   9
 
In seeking to achieve its investment objective, the Tax-Exempt Portfolio may
invest all or any part of its assets in Municipal Securities that are industrial
development bonds. Moreover, although the Portfolio does not currently intend to
do so on a regular basis, it may invest more than 25% of its assets in Municipal
Securities that are repayable out of revenue streams generated from economically
related projects or facilities, if such investment is deemed necessary or
appropriate by the Portfolio's investment manager. To the extent that the
Portfolio's assets are concentrated in Municipal Securities payable from
revenues on economically related projects and facilities, the Portfolio will be
subject to the risks presented by such projects to a greater extent than it
would be if the Portfolio's assets were not so concentrated.
 
From time to time, as a defensive measure or when acceptable short-term
Municipal Securities are not available, the Tax-Exempt Portfolio may invest in
taxable "temporary investments" that include: obligations of the U.S.
Government, its agencies or instrumentalities; debt securities rated within the
two highest grades by Moody's or S&P; commercial paper rated in the two highest
grades by either of such rating services; certificates of deposit of domestic
banks with assets of $1 billion or more; and any of the foregoing temporary
investments subject to repurchase agreements. Repurchase agreements are
discussed below. Interest income from temporary investments is taxable to
shareholders as ordinary income. Although the Portfolio is permitted to invest
in taxable securities (limited under normal market conditions to 20% of the
Portfolio's total assets), it is the Portfolio's primary intention to generate
income dividends that are not subject to federal income taxes. See "Dividends
and Taxes." For a description of the ratings, see "Appendix--Ratings of
Investments" in the Statement of Additional Information.
 
THE FUND. Each Portfolio may invest in repurchase agreements, which are
instruments under which a Portfolio acquires ownership of a security from a
broker-dealer or bank that agrees to repurchase the security at a mutually
agreed upon time and price (which price is higher than the purchase price),
thereby determining the yield during the Portfolio's holding period. Maturity of
the securities subject to repurchase may exceed one year. In the event of a
bankruptcy or other default of a seller of a repurchase agreement, a Portfolio
might have expenses in enforcing its rights, and could experience losses,
including a decline in the value of the underlying securities and loss of
income. A Portfolio will not purchase illiquid securities, including time
deposits and repurchase agreements maturing in more than seven days if, as a
result thereof, more than 10% of such Portfolio's net assets valued at the time
of the transaction would be invested in such securities.
 
Each Portfolio may invest in instruments having rates of interest that are
adjusted periodically or that "float" continuously according to formulae
intended to minimize fluctuation in values of the instruments ("Variable Rate
Securities"). The interest rate of Variable Rate Securities ordinarily is
determined by reference to or is a percentage of an objective standard such as a
bank's prime rate, the 90-day U.S. Treasury Bill rate, or the rate of return on
commercial paper or bank certificates of deposit. Generally, the changes in the
interest rate on Variable Rate Securities reduce the fluctuation in the market
value of such securities. Accordingly, as interest rates decrease or increase,
the potential for capital appreciation or depreciation is less than for
fixed-rate obligations. Some Variable Rate Securities ("Variable Rate Demand
Securities") have a demand feature entitling the purchaser to resell the
securities at an amount approximately equal to amortized cost or the principal
amount thereof plus accrued interest. As is the case for other Variable Rate
Securities, the interest rate on Variable Rate Demand Securities varies
according to some objective standard intended to minimize fluctuation in the
values of the instruments. Each Portfolio determines the maturity of Variable
Rate Securities in accordance with Rule 2a-7, which allows the Portfolio to
consider certain of such instruments as having maturities shorter than the
maturity date on the face of the instrument.
 
A Portfolio may not borrow money except as a temporary measure for extraordinary
or emergency purposes, and then only in an amount up to one-third of the value
of its total assets, in order to meet redemption requests without immediately
selling any portfolio securities. Any such borrowings under this provision will
not be collateralized. No Portfolio will borrow for leverage purposes.
 
                                        8
<PAGE>   10
 
The Fund has adopted for each Portfolio certain investment restrictions that are
presented in the Statement of Additional Information and that, together with the
investment objective and policies of such Portfolio (except for policies
designated as non-fundamental and limited in regard to the Tax-Exempt Portfolio
to the policies in the first and third paragraphs under "Tax-Exempt Portfolio"
above), cannot be changed without approval by holders of a majority of its
outstanding voting shares. As defined in the Investment Company Act of 1940,
this means with respect to a Portfolio the lesser of the vote of (a) 67% of the
shares of such Portfolio present at a meeting where more than 50% of the
outstanding shares of the Portfolio are present in person or by proxy or (b)
more than 50% of the outstanding shares of the Portfolio.
 
NET ASSET VALUE
 
The net asset value per share of each Portfolio is calculated by dividing the
total assets of such Portfolio less its liabilities by the total number of its
shares outstanding. The net asset value per share of each Portfolio is
determined on each day the New York Stock Exchange ("Exchange") is open for
trading, at 11:00 a.m., 1:00 p.m. and 3:00 p.m. Chicago time for the Money
Market and Government Securities Portfolios and at 11:00 a.m. and 3:00 p.m.
Chicago time for the Tax-Exempt Portfolio. Fund shares are sold at the net asset
value next determined after an order and payment are received in the form
described under "Purchase of Shares." Each Portfolio seeks to maintain its net
asset value at $1.00 per share.
 
Each Portfolio values its portfolio instruments at amortized cost in accordance
with Rule 2a-7 under the Investment Company Act of 1940, which means that they
are valued at their acquisition cost (as adjusted for amortization of premium or
accretion of discount) rather than at current market value. Calculations are
made to compare the value of each Portfolio's investments valued at amortized
cost with market-based values. Market-based valuations are obtained by using
actual quotations provided by market makers, estimates of market value, or
values obtained from yield data relating to classes of money market instruments
published by reputable sources at the mean between the bid and asked prices for
the instruments. If a deviation of 1/2 of 1% or more were to occur between a
Portfolio's net asset value per share calculated by reference to market-based
values and the Portfolio's $1.00 per share net asset value, or if there were any
other deviation that the Board of Trustees believed would result in a material
dilution to shareholders or purchasers, the Board of Trustees would promptly
consider what action, if any, should be initiated. In order to value its
investments at amortized cost, the Portfolios purchase only securities with a
maturity of one year or less and maintain a dollar-weighted average portfolio
maturity of 90 days or less. In addition, the Portfolios limit their portfolio
investments to securities that meet the quality and diversification requirements
of Rule 2a-7.
 
PURCHASE OF SHARES
 
Shares of each Portfolio of the Fund are sold at net asset value through
selected financial services firms, such as broker-dealers and banks ("firms").
Investors must indicate the Portfolio in which they wish to invest. The Fund has
established a minimum initial investment for each Portfolio of $1,000 and $100
for subsequent investments, but these minimums may be changed at any time in
management's discretion. Firms offering Fund shares may set higher minimums for
accounts they service and may change such minimums at their discretion.
 
The Fund seeks to have its Portfolios as fully invested as possible at all times
in order to achieve maximum income. Since each Portfolio will be investing in
instruments that normally require immediate payment in Federal Funds (monies
credited to a bank's account with its regional Federal Reserve Bank), the Fund
has adopted procedures for the convenience of its shareholders and to ensure
that each Portfolio receives investable funds. Orders for purchase of shares of
a Portfolio received by wire transfer in the form of Federal Funds will be
effected at the next determined net asset value. Shares purchased by wire will
receive that day's dividend if effected at or prior to the 1:00 p.m. Chicago
time net asset value determination for the Money Market and the Government
Securities Portfolios and at or prior to the 11:00 a.m. Chicago time net asset
value determination for the Tax-Exempt Portfolio, otherwise such shares will
receive the dividend for the next business day. Orders for purchase
 
                                        9
<PAGE>   11
 
accompanied by a check or other negotiable bank draft will be accepted and
effected as of 3:00 p.m. Chicago time on the next business day following receipt
and such shares will receive the dividend for the business day following the day
the purchase is effected. If an order is accompanied by a check drawn on a
foreign bank, funds must normally be collected on such check before shares will
be purchased. See "Purchase and Redemption of Shares" in the Statement of
Additional Information.
 
If payment is wired in Federal Funds, the payment should be directed to State
Street Bank and Trust Company, 225 Franklin Street, Boston, Massachusetts 02110,
the sub-custodian for the Fund. If payment is to be wired, call the firm from
which you received this prospectus for proper instructions.
 
CLIENTS OF FIRMS. Firms provide varying arrangements for their clients with
respect to the purchase and redemption of Fund shares and the confirmation
thereof and may arrange with their clients for other investment or
administrative services. Such firms are responsible for the prompt transmission
of purchase and redemption orders. Some firms may establish higher minimum
investment requirements than set forth above. Such firms may independently
establish and charge additional amounts to their clients for their services,
which charges would reduce their clients' yield or return. Firms may also hold
Fund shares in nominee or street name as agent for and on behalf of their
clients. In such instances, the Fund's transfer agent will have no information
with respect to or control over the accounts of specific shareholders. Such
shareholders may obtain access to their accounts and information about their
accounts only from their firm. Certain of these firms may receive compensation
through the Fund's Shareholder Service Agent for record-keeping and other
expenses relating to these nominee accounts. In addition, certain privileges
with respect to the purchase and redemption of shares (such as check writing
redemptions) or the reinvestment of dividends may not be available through such
firms or may only be available subject to certain conditions or limitations.
Some firms may participate in a program allowing them access to their clients'
accounts for servicing including, without limitation, transfers of registration
and dividend payee changes; and may perform functions such as generation of
confirmation statements and disbursement of cash dividends. The prospectus
should be read in connection with such firm's material regarding its fees and
services.
 
OTHER INFORMATION. The Fund reserves the right to withdraw all or any part of
the offering made by this prospectus or to reject purchase orders, without prior
notice. The Fund also reserves the right at any time to waive or increase the
minimum investment requirements. All orders to purchase shares of a Portfolio
are subject to acceptance by the Fund and are not binding until confirmed or
accepted in writing. Any purchase that would result in total account balances
for a single shareholder in excess of $3 million is subject to prior approval by
the Fund. Share certificates are issued only on request. A $10 service fee will
be charged when a check for the purchase of shares is returned because of
insufficient or uncollected funds or a stop payment order.
 
Shareholders should direct their inquiries to the firm from which they received
this prospectus or to Kemper Service Company, the Fund's "Shareholder Service
Agent," 811 Main Street, Kansas City, Missouri 64105-2005.
 
REDEMPTION OF SHARES
 
GENERAL. Upon receipt by the Shareholder Service Agent of a request in the form
described below, shares of a Portfolio will be redeemed by the Fund at the next
determined net asset value. If processed at 3 p.m. Chicago time, the shareholder
will receive that day's dividend. A shareholder may use either the regular or
expedited redemption procedures. Shareholders who redeem all their shares of a
Portfolio will receive the net asset value of such shares and all declared but
unpaid dividends on such shares.
 
If shares of a Portfolio to be redeemed were purchased by check or through an
Automated Clearing House ("ACH") transaction, the Fund may delay transmittal of
redemption proceeds until it has determined that collected funds have been
received for the purchase of such shares, which will be up to 10 days from
receipt by the Fund of the purchase amount. Shareholders may not use expedited
redemption procedures (wire transfer or Redemption Check) until the shares being
redeemed have been owned for at least 10 days, and shareholders may
 
                                       10
<PAGE>   12
 
not use such procedures to redeem shares held in certificated form. There is no
delay when shares being redeemed were purchased by wiring Federal Funds.
 
If shares being redeemed were acquired from an exchange of shares of a mutual
fund that were offered subject to a contingent deferred sales charge as
described in the prospectus for that other fund, the redemption of such shares
by the Fund may be subject to a contingent deferred sales charge as explained in
such prospectus.
 
Shareholders can request the following telephone privileges: expedited wire
transfer redemptions, ACH transactions and exchange transactions for individual
and institutional accounts and pre-authorized telephone redemption transactions
for certain institutional accounts. Shareholders may choose these privileges on
the account application or by contacting the Shareholder Service Agent for
appropriate instructions. Please note that the telephone exchange privilege is
automatic unless the shareholder refuses it on the account application. The Fund
or its agents may be liable for any losses, expenses or costs arising out of
fraudulent or unauthorized telephone requests pursuant to these privileges,
unless the Fund or its agents reasonably believe, based upon reasonable
verification procedures, that the telephone instructions are genuine. THE
SHAREHOLDER WILL BEAR THE RISK OF LOSS, including loss resulting from fraudulent
or unauthorized transactions, as long as the reasonable verification procedures
are followed. The verification procedures include recording instructions,
requiring certain identifying information before acting upon instructions and
sending written confirmations.
 
Because of the high cost of maintaining small accounts, the Fund reserves the
right to redeem an account that falls below the minimum investment level,
currently $1,000. A shareholder will be notified in writing and will be allowed
60 days to make additional purchases to bring the account value up to the
minimum investment level before the Fund redeems the shareholder account.
 
Firms provide varying arrangements for their clients to redeem Fund shares. Such
firms may independently establish and charge additional amounts to their clients
for such services.
 
REGULAR REDEMPTIONS. When shares are held for the account of a shareholder by
the Fund's transfer agent, the shareholder may redeem them by sending a written
request with signatures guaranteed to Kemper Service Company, P.O. Box 419153,
Kansas City, Missouri 64141-6153. When certificates for shares have been issued,
they must be mailed to or deposited with the Shareholder Service Agent, along
with a duly endorsed stock power and accompanied by a written request for
redemption. Redemption requests and a stock power must be endorsed by the
account holder with signatures guaranteed by a commercial bank, trust company,
savings and loan association, federal savings bank, member firm of a national
securities exchange or other eligible financial institution. The redemption
request and stock power must be signed exactly as the account is registered
including any special capacity of the registered owner. Additional documentation
may be requested, and a signature guarantee is normally required, from
institutional and fiduciary account holders, such as corporations, custodians
(e.g., under the Uniform Transfers to Minors Act), executors, administrators,
trustees, or guardians.
 
TELEPHONE REDEMPTIONS. If the proceeds of the redemption are $50,000 or less and
the proceeds are payable to the shareholder of record at the address of record,
normally a telephone request or a written request by any one account holder
without a signature guarantee is sufficient for redemptions by individual or
joint account holders, and trust, executor and guardian account holders
(excluding custodial accounts for gifts and transfers to minors) provided the
trustee, executor or guardian is named in the account registration. Other
institutional account holders and guardian account holders of custodial accounts
for gifts and transfers to minors may exercise this special privilege of
redeeming shares by telephone request or written request without signature
guarantee subject to the same conditions as individual account holders and
subject to the limitations on liability described under "General" above,
provided that this privilege has been pre-authorized by the institutional
account holder or guardian account holder by written instruction to the
Shareholder Service Agent with signatures guaranteed. Telephone requests may be
made by calling 1-800-231-8568. Shares purchased by check or through an ACH
transaction may not be redeemed under this privilege of redeeming shares by
telephone request until such shares have been owned for at least 10 days. This
privilege of redeeming shares by telephone request or by written request without
a signature guarantee may not be used to redeem shares held in certificated form
and may not be
 
                                       11
<PAGE>   13
 
used if the shareholder's account has had an address change within 30 days of
the redemption request. During periods when it is difficult to contact the
Shareholder Service Agent by telephone, it may be difficult to use the telephone
redemption privilege, although investors can still redeem by mail. The Fund
reserves the right to terminate or modify this privilege at any time.
 
EXPEDITED WIRE TRANSFER REDEMPTIONS. If the account holder has given
authorization for expedited wire redemption to the account holder's brokerage or
bank account, shares can be redeemed and proceeds sent by a federal wire
transfer to a single previously designated account. Requests received by the
Shareholder Service Agent prior to 11:00 a.m. Chicago time will result in shares
being redeemed that day and normally the proceeds will be sent to the designated
account that day. Once authorization is on file, the Shareholder Service Agent
will honor requests by telephone at 1-800-231-8568 or in writing, subject to the
limitations on liability described under "General" above. The Fund is not
responsible for the efficiency of the federal wire system or the account
holder's financial services firm or bank. The Fund currently does not charge the
account holder for wire transfers. The account holder is responsible for any
charges imposed by the account holder's firm or bank. There is a $1,000 wire
redemption minimum. To change the designated account to receive wire redemption
proceeds, send a written request to the Shareholder Service Agent with
signatures guaranteed as described above or contact the firm through which
shares of the Fund were purchased. Shares purchased by check or through an ACH
transaction may not be redeemed by wire transfer until the shares have been
owned for at least 10 days. Account holders may not use this procedure to redeem
shares held in certificated form. During periods when it is difficult to contact
the Shareholder Service Agent by telephone, it may be difficult to use the
expedited wire transfer redemption privilege. The Fund reserves the right to
terminate or modify this privilege at any time.
 
EXPEDITED REDEMPTIONS BY DRAFT. Upon request, shareholders will be provided with
drafts to be drawn on the Fund ("Redemption Checks"). These Redemption Checks
may be made payable to the order of any person for not more than $5 million.
Shareholders should not write Redemption Checks in an amount less than $250
since a $10 service fee will be charged as described below. When a Redemption
Check is presented for payment, a sufficient number of full and fractional
shares in the shareholder's account will be redeemed as of the next determined
net asset value to cover the amount of the Redemption Check. This will enable
the shareholder to continue earning dividends until the Fund receives the
Redemption Check. A shareholder wishing to use this method of redemption must
complete and file an Account Information Form which is available from the Fund
or firms through which shares were purchased. Redemption Checks should not be
used to close an account since the account normally includes accrued but unpaid
dividends. The Fund reserves the right to terminate or modify this privilege at
any time. This privilege may not be available through some firms that distribute
shares of the Fund. In addition, firms may impose minimum balance requirements
in order to obtain this feature. Firms may also impose fees to investors for
this privilege or establish variations of minimum check amounts if approved by
the Fund.
 
Unless one signer is authorized on the Account Information Form, Redemption
Checks must be signed by all account holders. Any change in the signature
authorization must be made by written notice to the Shareholder Service Agent.
Shares purchased by check or through an ACH transaction may not be redeemed by
Redemption Check until the shares have been on the Fund's books for at least 10
days. Shareholders may not use this procedure to redeem shares held in
certificated form. The Fund reserves the right to terminate or modify this
privilege at any time.
 
The Fund may refuse to honor Redemption Checks whenever the right of redemption
has been suspended or postponed, or whenever the account is otherwise impaired.
A $10 service fee will be charged when a Redemption Check is presented to redeem
Fund shares in excess of the value of a Fund account or in an amount less than
$250; when a Redemption Check is presented that would require redemption of
shares that were purchased by check or ACH transaction within 10 days; or when
"stop payment" of a Redemption Check is requested.

SPECIAL FEATURES
 
Certain firms that offer shares of the Fund also provide special redemption
features through charge or debit cards and checks that redeem Fund shares.
Various firms have different charges for their services. Shareholders should
obtain information from their firm with respect to any special redemption
features, applicable charges, minimum balance requirements and special rules of
the cash management program being offered.
 
Information about the following special features is contained in the Statement
of Additional Information; and further information may be obtained without
charge from KDI: Tax Sheltered Retirement Programs; Systematic Withdrawal
Program; Exchange Privilege and Automated Clearing House Programs.
 
DIVIDENDS AND TAXES
 
Dividends are declared daily and paid monthly. Shareholders may select one of
the following ways to receive dividends.
 
1. REINVEST DIVIDENDS at net asset value into additional shares of the same
Portfolio. Dividends are normally reinvested on the 21st of each month if a
business day, otherwise on the next business day. Dividends will be reinvested
unless the shareholder elects to receive them in cash.
 
2. RECEIVE DIVIDENDS IN CASH, if so requested. Checks will be mailed monthly to
the shareholder or any person designated by the shareholder.
 
The Fund reinvests dividend checks (and future dividends) in shares of the Fund
if checks are returned as undeliverable. Dividends and other distributions in
the aggregate amount of $10 or less are automatically reinvested in shares of
the Fund unless the shareholder requests that such policy not be applied to the
shareholder's account.
 
TAXABLE PORTFOLIOS. The Money Market Portfolio and the Government Securities
Portfolio each intend to continue to qualify as a regulated investment company
under Subchapter M of the Internal Revenue Code (the "Code") and, if so
qualified, will not be subject to Federal income taxes to the extent its
earnings are distributed. Dividends derived from interest and short-term capital
gains are taxable as ordinary income whether received in cash or reinvested in
additional shares. Dividends from these Portfolios do not qualify for the
dividends received deduction available to corporate shareholders.
 
TAX-EXEMPT PORTFOLIO. The Tax-Exempt Portfolio intends to continue to qualify
under the Code as a regulated investment company and, if so qualified, will not
be liable for Federal income taxes to the extent its earnings are distributed.
This Portfolio also intends to meet the requirements of the Code applicable to
regulated investment companies distributing tax-exempt interest dividends and,
accordingly, dividends representing net interest received on Municipal
Securities will not be includable by shareholders in their gross income for
Federal income tax purposes, except to the extent such interest is subject to
the alternative minimum tax as discussed below. Dividends representing taxable
net investment income (such as net interest income from temporary investments in
obligations of the U.S. Government) and net short-term capital gains, if any,
are taxable to shareholders as ordinary income.
 
Net interest on certain "private activity bonds" issued on or after August 8,
1986 is treated as an item of tax preference and may, therefore, be subject to
both the individual and corporate alternative minimum tax. To the extent
provided by regulations to be issued by the Secretary of the Treasury,
exempt-interest dividends from the Tax-Exempt Portfolio are to be treated as
interest on private activity bonds in proportion to the interest income the
Portfolio receives from private activity bonds, reduced by allowable deductions.
For the 1995 calendar year 16% of the net interest income was derived from
"private activity bonds."
 
Exempt-interest dividends, except to the extent of interest from "private
activity bonds," are not treated as a tax-preference item. For a corporate
shareholder, however, such dividends will be included in determining such
 
                                       13
<PAGE>   15
 
corporate shareholder's "adjusted current earnings." Seventy-five percent of the
excess, if any, of "adjusted current earnings" over the corporate shareholder's
other alternative minimum taxable income with certain adjustments will be a
tax-preference item. Corporate shareholders are advised to consult their tax
advisers with respect to alternative minimum tax consequences.
 
Shareholders will be required to disclose on their Federal income tax returns
the amount of tax-exempt interest earned during the year, including
exempt-interest dividends received from the Tax-Exempt Portfolio.
 
Individuals whose modified income exceeds a base amount will be subject to
Federal income tax on up to 85% of their Social Security benefits. Modified
income includes adjusted gross income, tax-exempt interest, including
exempt-interest dividends from the Tax-Exempt Portfolio, and 50% of Social
Security benefits.
 
The tax exemption of dividends from the Tax-Exempt Portfolio for Federal income
tax purposes does not necessarily result in exemption under the income or other
tax laws of any state or local taxing authority. The laws of the several states
and local taxing authorities vary with respect to the taxation of such income
and shareholders of the Portfolios are advised to consult their own tax advisers
as to the status of their accounts under state and local tax laws.
 
THE FUND. Dividends declared in October, November or December to shareholders of
record as of a date in one of those months and paid during the following January
are treated as paid on December 31 of the calendar year in which declared for
Federal income tax purposes. The Fund may adjust its schedule for dividend
reinvestment for the month of December to assist in complying with the reporting
and minimum distribution requirements contained in the Code.
 
Each Portfolio is required by law to withhold 31% of taxable dividends paid to
certain shareholders who do not furnish a correct taxpayer identification number
(in the case of individuals a social security number) and in certain other
circumstances. Trustees of qualified retirement plans and 403(b)(7) accounts are
required by law to withhold 20% of the taxable portion of any distribution that
is eligible to be "rolled over." The 20% withholding requirement does not apply
to distributions from IRAs or any part of a distribution that is transferred
directly to another qualified retirement plan, 403(b)(7) account, or IRA.
Shareholders should consult their tax advisers regarding the 20% withholding
requirement.
 
Shareholders normally will receive monthly confirmations of dividends and of
purchase and redemption transactions except that confirmations of dividend
reinvestment for IRAs and other fiduciary accounts for which Investors Fiduciary
Trust Company serves as trustee will be sent quarterly. Firms may provide
varying arrangements with their clients with respect to confirmations. Tax
information will be provided annually. Shareholders are encouraged to retain
copies of their account confirmation statements or year-end statements for tax
reporting purposes. However, those who have incomplete records may obtain
historical account transaction information at a reasonable fee.
 
INVESTMENT MANAGER AND SHAREHOLDER SERVICES
 
INVESTMENT MANAGER. Zurich Kemper Investments, Inc. ("ZKI"), 120 South LaSalle
Street, Chicago, Illinois 60603, is the investment manager of the Fund and
provides the Fund with continuous professional investment supervision. ZKI is
one of the largest investment managers in the country and has been engaged in
the management of investment funds for more than forty-six years. ZKI and its
affiliates provide investment advice and manage investment portfolios for the
Kemper Funds, affiliated insurance companies and other corporate, pension,
profit-sharing and individual accounts representing approximately $78 billion
under management. ZKI acts as investment manager for 29 open-end and seven
closed-end investment companies, with 76 separate investment portfolios,
representing more than 3 million shareholder accounts.
 
Responsibility for overall management of the Fund rests with its Board of
Trustees and officers. Professional investment supervision is provided by ZKI.
The investment management agreement provides that ZKI shall act as
 
                                       14
<PAGE>   16
 
the Fund's investment adviser, manage its investments and provide it with
various services and facilities. For the services and facilities furnished to
the Money Market, Government Securities and Tax-Exempt Portfolios, the Fund pays
ZKI an annual investment management fee, payable monthly, on a graduated basis
of .22% of the first $500 million of combined average daily net assets of such
Portfolios, .20% of the next $500 million, .175% of the next $1 billion, .16% of
the next $1 billion and .15% of combined average daily net assets of such
Portfolios over $3 billion. ZKI has agreed to temporarily waive its management
fee and absorb operating expenses of each Portfolio to the extent, if any, that
they exceed the following percentages of average daily net assets of the
Portfolios: Money Market Portfolio (1.00%), Government Securities Portfolio
(.90%) and Tax-Exempt Portfolio (.80%). For this purpose, Portfolio operating
expenses do not include taxes, interest, extraordinary expenses, brokerage
commissions or transaction costs. Upon notice to the Fund, ZKI may at any time
terminate this waiver or absorption of operating expenses. In addition, from
time to time, ZKI may voluntarily absorb certain additional operating expenses
of the Portfolios. The level of this voluntary expense absorption shall be in
ZKI's discretion and is in addition to ZKI's agreement to temporarily absorb
certain operating expenses of the Portfolios described above. For its services
as investment adviser and manager and for facilities furnished during the fiscal
year ended April 30, 1996, ZKI received management fees aggregating .17%, .06%
and .04% of the average daily net assets of the Money Market Portfolio, the
Government Securities Portfolio and the Tax-Exempt Portfolio, respectively,
which includes the effect of the fee waiver.
 
DISTRIBUTOR AND ADMINISTRATOR. Pursuant to an administration, shareholder
services and distribution agreement ("distribution agreement"), Kemper
Distributors, Inc. ("KDI"), 120 South LaSalle Street, Chicago, Illinois 60603,
an affiliate of ZKI, serves as primary administrator, distributor and principal
underwriter for the Fund to provide information and services for existing and
potential shareholders. The distribution agreement provides that KDI shall
appoint various financial services firms to provide a cash management service
for their customers or clients through the Fund. The firms are to provide such
office space and equipment, telephone facilities, personnel and literature
distribution as is necessary or appropriate for providing information and
services to the firms' clients. For its services under the administration
agreement, KDI receives a distribution services fee, payable monthly, at the
annual rate of .60% of average daily net assets from the Money Market and
Government Securities Portfolios and .50% of average daily net assets from the
Tax-Exempt Portfolio. The fee is accrued daily as an expense of the Portfolios.
As principal underwriter for the Fund, KDI acts as agent of the Fund in the sale
of its shares.
 
KDI has related administration services and selling group agreements ("services
agreements") with various firms to provide cash management and other services
for Fund shareholders. KDI normally pays such firms for services at a maximum
annual rate of .60% of average daily net assets of those accounts in the Money
Market and Government Securities Portfolios that they maintain and service and
 .50% of average daily net assets of those accounts in the Tax-Exempt Portfolio
that they maintain and service. KDI may in its discretion pay certain firms
additional amounts. Since the distribution agreement provides for fees that are
used by KDI to pay for distribution and administration services, the
distribution agreement along with the related services agreements and the plan
contained therein are approved and reviewed in accordance with Rule 12b-1 under
the Investment Company Act of 1940, which regulates the manner in which an
investment company may, directly or indirectly, bear the expenses of
distributing its shares.
 
Since the fee payable to KDI under the distribution agreement is based upon
percentages of the average daily net assets of the Portfolios as provided above
and not upon the actual expenditures of KDI, the expenses of KDI, which may
include overhead expense, may be more or less than the fees received by it under
the distribution agreement. For example, during the fiscal year ended April 30,
1996, KDI incurred expenses under the distribution agreement of approximately
$4,093,000, while it received an aggregate fee under the distribution agreement
of $3,920,000. If the distribution agreement is terminated in accordance with
its terms, the obligation of the Fund to make payments to KDI pursuant to the
distribution agreement will cease and the Fund will not be required to make any
payments past the termination date. Thus, there is no legal obligation for the
Fund to pay any expenses incurred by KDI in excess of its fees under the
distribution agreement, if for any reason the distribution agreement
 
                                       15
<PAGE>   17
 
is terminated in accordance with its terms. Future fees under the distribution
agreement may or may not be sufficient to reimburse KDI for its cumulative
expenses incurred.
 
KDI also has agreements with banking firms to provide administrative and other
services, except for certain underwriting or distribution services that banks
may be prohibited from providing under the Glass-Steagall Act, for their clients
who wish to invest in the Fund. If the Glass-Steagall Act should prevent banking
firms from acting in any capacity or providing any of the described services,
management will consider what action, if any, is appropriate. Management does
not believe that termination of a relationship with a bank would result in any
material adverse consequences to the Fund. Banks or other financial services
firms may be subject to various state laws regarding the services described
above and may be required to register as dealers pursuant to state law.
 
CUSTODIAN, TRANSFER AGENT AND SHAREHOLDER SERVICE AGENT. Investors Fiduciary
Trust Company ("IFTC"), 127 West 10th Street, Kansas City, Missouri 64105, as
custodian, and State Street Bank and Trust Company, 225 Franklin Street, Boston,
Massachusetts 02110, as sub-custodian, have custody of all securities and cash
of the Fund. They attend to the collection of principal and income, and payment
for and collection of proceeds of securities bought and sold by the Fund. IFTC
also is the Fund's transfer and dividend-paying agent. Pursuant to a services
agreement with IFTC, Kemper Service Company, 811 Main Street, Kansas City,
Missouri 64105, an affiliate of ZKI, serves as Shareholder Service Agent of the
Fund.
 
PERFORMANCE
 
The Fund may advertise several types of performance information including
"yield," "effective yield" and, for the Tax-Exempt Portfolio only, "tax
equivalent yield." Each of these figures is based upon historical earnings and
is not representative of the future performance of a Portfolio. The yield of a
Portfolio refers to the net investment income generated by a hypothetical
investment in the Portfolio over a specific seven-day period. This net
investment income is then annualized, which means that the net investment income
generated during the seven-day period is assumed to be generated each week over
an annual period and is shown as a percentage of the investment. The effective
yield is calculated similarly, but the net investment income earned by the
investment is assumed to be compounded weekly when annualized. The effective
yield will be slightly higher than the yield due to this compounding effect. Tax
equivalent yield is the yield that a taxable investment must generate in order
to equal the Tax-Exempt Portfolio's yield for an investor in a stated Federal
income tax bracket (normally assumed to be the maximum tax rate). Tax equivalent
yield is based upon, and will be higher than, the portion of the Tax-Exempt
Portfolio's yield that is tax-exempt.
 
The performance of a Portfolio may be compared to that of other money market
mutual funds or mutual fund indexes as reported by independent mutual fund
reporting services such as Lipper Analytical Services, Inc. A Portfolio's
performance and its relative size may be compared to other money market mutual
funds as reported by IBC/Donoghue's Money Fund Report(R) or Money Market
Insight(R), reporting services on money market funds. Investors may want to
compare a Portfolio's performance to that of various bank products as reported
by BANK RATE MONITORTM, a financial reporting service that weekly publishes
average rates of bank and thrift institution money market deposit accounts and
interest bearing checking accounts or various certificate of deposit indexes.
The performance of a Portfolio also may be compared to that of U.S. Treasury
bills and notes. Certain of these alternative investments may offer fixed rates
of return and guaranteed principal and may be insured. In addition, investors
may want to compare a Portfolio's performance to the Consumer Price Index either
directly or by calculating its "real rate of return," which is adjusted for the
effects of inflation.
 
Information may be quoted from publications such as MORNINGSTAR, INC., THE WALL
STREET JOURNAL, MONEY MAGAZINE, FORBES, BARRON'S, FORTUNE, THE CHICAGO TRIBUNE,
USA TODAY, INSTITUTIONAL INVESTOR AND REGISTERED REPRESENTATIVE. The Fund may
depict the historical performance of the securities in which a Portfolio may
invest over periods reflecting a variety of market or economic conditions either
alone or in comparison with alternative investments, performance indexes of
those investments or economic indicators. The Fund may also describe its
portfolio holdings and depict its size or relative size compared to other mutual
funds, the number and make-up of its shareholder base and other descriptive
factors concerning the Fund.
 
                                       16

Each Portfolio's yield will fluctuate. Shares of the Fund are not insured.
Additional information concerning a Portfolio's performance appears in the
Statement of Additional Information.
 
CAPITAL STRUCTURE
 
The Fund is an open-end, diversified, management investment company, organized
as a business trust under the laws of Massachusetts on September 7, 1989. The
Fund may issue an unlimited number of shares of beneficial interest in one or
more series ("Portfolios"), all having no par value, which may be divided by the
Board of Trustees into classes of shares, subject to compliance with the
Securities and Exchange Commission regulations permitting the creation of
separate classes of shares. The Fund's shares are not currently divided into
classes. While only shares of the three previously described Portfolios are
presently being offered, the Board of Trustees may authorize the issuance of
additional Portfolios if deemed desirable. Since the Fund offers multiple
Portfolios, it is known as a "series company." Shares of each Portfolio have
equal noncumulative voting rights and equal rights with respect to dividends,
assets and liquidation of such Portfolio subject to any preferences, rights or
privileges of any classes of shares within the Portfolio. Generally, each class
of shares issued by a particular Portfolio would differ as to the allocation of
certain expenses of the Portfolio, such as distribution and administrative
expenses, permitting, among other things, different levels of services or
methods of distribution among various classes. Shares are fully paid and
nonassessable when issued, are transferable without restriction and have no
preemptive or conversion rights. The Fund is not required to hold annual
shareholders' meetings and does not intend to do so. However, it will hold
special meetings as required or deemed desirable for such purposes as electing
trustees, changing fundamental policies or approving an investment management
agreement. Subject to the Agreement and Declaration of Trust of the Fund,
shareholders may remove trustees. Shareholders will vote by Portfolio and not in
the aggregate or by class except when voting in the aggregate is required under
the Investment Company Act of 1940, such as for the election of trustees, or
when the Board of Trustees determines that voting by class is appropriate.

INVESTMENT RESTRICTIONS
 
The Fund has adopted for the Money Market Portfolio, the Government Securities
Portfolio and the Tax-Exempt Portfolio certain investment restrictions which,
together with the investment objective and policies of each Portfolio, cannot be
changed for a Portfolio without approval by holders of a majority of its
outstanding voting shares. As defined in the Investment Company Act of 1940,
this means the lesser of the vote of (a) 67% of the shares of the Portfolio
present at a meeting where more than 50% of the outstanding shares are present
in person or by proxy or (b) more than 50% of the outstanding shares of the
Portfolio.
 
The Money Market Portfolio and the Government Securities Portfolio individually
may not:
 
(1) Purchase securities of any issuer (other than obligations of, or guaranteed
by, the United States Government, its agencies or instrumentalities) if, as a
result, more than 5% of the value of the Portfolio's assets would be invested in
securities of that issuer.
 
(2) Purchase more than 10% of any class of securities of any issuer. All debt
securities and all preferred stocks are each considered as one class.
 
(3) Make loans to others (except through the purchase of debt obligations or
repurchase agreements in accordance with its investment objective and policies).
 
(4) Borrow money except as a temporary measure for extraordinary or emergency
purposes and then only in an amount up to one-third of the value of its total
assets, in order to meet redemption requests without immediately selling any
money market instruments (any such borrowings under this section will not be
collateralized). If, for any reason, the current value of the Portfolio's total
assets falls below an amount equal to three times the amount of its indebtedness
from money borrowed, the Portfolio will, within three days (not including
Sundays and holidays), reduce its indebtedness to the extent necessary. The
Portfolio will not borrow for leverage purposes.
 
(5) Make short sales of securities, or purchase any securities on margin except
to obtain such short-term credits as may be necessary for the clearance of
transactions.
 
(6) Write, purchase or sell puts, calls or combinations thereof.
 
(7) Purchase or retain the securities of any issuer if any of the officers,
trustees or directors of the Fund or its investment adviser owns beneficially
more than 1/2 of 1% of the securities of such issuer and together own more than
5% of the securities of such issuer.
 
(8) Invest for the purpose of exercising control or management of another
issuer.
 
(9) Invest in commodities or commodity futures contracts or in real estate (or
real estate limited partnerships), although it may invest in securities which
are secured by real estate and securities of issuers which invest or deal in
real estate.
 
(10) Invest in interests in oil, gas or other mineral exploration or development
programs or leases, although it may invest in the securities of issuers which
invest in or sponsor such programs.
 
(11) Underwrite securities issued by others except to the extent the Portfolio
may be deemed to be an underwriter, under the federal securities laws, in
connection with the disposition of portfolio securities.
 
(12) Issue senior securities as defined in the Investment Company Act of 1940.
 
Additionally, the Money Market Portfolio may not:
 
(13) Concentrate 25% or more of the value of the Portfolio's assets in any one
industry; provided, however, that (a) the Portfolio reserves freedom of action
to invest up to 100% of its assets in obligations of, or guaranteed by, the
United States Government, its agencies or instrumentalities in accordance with
its investment objective and policies and (b) the Portfolio will invest at least
25% of its assets in obligations issued by banks in accordance
 
                                       B-1
<PAGE>   22
 
with its investment objective and policies. However, the Portfolio may, in the
discretion of its investment adviser, invest less than 25% of its assets in
obligations issued by banks whenever the Portfolio assumes a temporary defensive
posture.
 
The Tax-Exempt Portfolio may not:
 
(1) Purchase securities if as a result of such purchase more than 25% of the
Portfolio's total assets would be invested in any industry or in any one state.
Municipal Securities and obligations of, or guaranteed by, the U.S. Government,
its agencies or instrumentalities are not considered an industry for purposes of
this restriction.
 
(2) Purchase securities of any issuer (other than obligations of, or guaranteed
by, the U.S. Government, its agencies or instrumentalities) if as a result more
than 5% of the value of the Portfolio's assets would be invested in the
securities of such issuer. For purposes of this limitation, the Portfolio will
regard the entity that has the primary responsibility for the payment of
interest and principal as the issuer.
 
(3) Make loans to others (except through the purchase of debt obligations or
repurchase agreements in accordance with its investment objective and policies).
 
(4) Borrow money except as a temporary measure for extraordinary or emergency
purposes and then only in an amount up to one-third of the value of its total
assets, in order to meet redemption requests without immediately selling any
money market instruments (any such borrowings under this section will not be
collateralized). If, for any reason, the current value of the Portfolio's total
assets falls below an amount equal to three times the amount of its indebtedness
from money borrowed, the Portfolio will, within three days (not including
Sundays and holidays), reduce its indebtedness to the extent necessary. The
Portfolio will not borrow for leverage purposes.
 
(5) Make short sales of securities or purchase securities on margin, except to
obtain such short-term credits as may be necessary for the clearance of
transactions.
 
(6) Write, purchase or sell puts, calls or combinations thereof, although the
Portfolio may purchase Municipal Securities subject to Standby Commitments in
accordance with its investment objective and policies.
 
(7) Purchase or retain the securities of any issuer if any of the officers,
trustees or directors of the Fund or its investment adviser owns beneficially
more than 1/2 of 1% of the securities of such issuer and together own more than
5% of the securities of such issuer.
 
(8) Invest for the purpose of exercising control or management of another
issuer.
 
(9) Invest in commodities or commodity futures contracts or in real estate (or
real estate limited partnerships) except that the Portfolio may invest in
Municipal Securities secured by real estate or interests therein.
 
(10) Invest in interests in oil, gas or other mineral exploration or development
programs or leases, although it may invest in Municipal Securities of issuers
which invest in or sponsor such programs or leases.
 
(11) Underwrite securities issued by others except to the extent the Portfolio
may be deemed to be an underwriter, under the federal securities laws, in
connection with the disposition of portfolio securities.
 
(12) Issue senior securities as defined in the Investment Company Act of 1940.
 
If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage beyond the specified limit resulting from a
change in values or net assets will not be considered a violation. The
Portfolios did not borrow in the latest fiscal period and have no present
intention of borrowing during the coming year as permitted for each Portfolio by
investment restriction number 4. In any event, borrowings would only be made as
permitted by such restrictions. The Tax-Exempt Portfolio may invest more than
25% of its total assets in industrial development bonds. The Fund has agreed
with certain state regulators that, so long as required by any state where the
Fund's shares are offered for sale, the Money Market Portfolio and the
Government Securities
 
                                       B-2
<PAGE>   23
 
Portfolio of the Fund, as a non-fundamental policy that may be changed without
shareholder vote, individually may not:
 
(i) Invest more than 5% of the Portfolio's total assets in securities of issuers
(other than obligations of, or guaranteed by, the United States Government, its
agencies or instrumentalities) which with their predecessors have a record of
less than three years continuous operation.
 
(ii) Invest more than 5% of the Portfolio's total assets in securities
restricted as to disposition under the federal securities laws (except
commercial paper issued under Section 4(2) of the Securities Act of 1933).
 
(iii) Purchase securities of other investment companies, except in connection
with a merger, consolidation, reorganization or acquisition of assets.
 
In addition, the Fund has agreed with certain state regulators that, so long as
required by any state where the Fund's shares are offered for sale, the
Tax-Exempt Portfolio of the Fund, as a non-fundamental policy that may be
changed without shareholder vote, may not:
 
(i) Invest more than 5% of the Portfolio's total assets in industrial
development bonds sponsored by companies which with their predecessors have less
than three years' continuous operation.
 
(ii) Invest more than 5% of the Portfolio's total assets in securities
restricted as to disposition under the Federal securities laws (except
commercial paper issued under Section 4(2) of the Securities Act of 1933).
 
(iii) Purchase securities of other investment companies, except in connection
with a merger, consolidation, reorganization or acquisition of assets.
 
MUNICIPAL SECURITIES
 
Municipal Securities which the Tax-Exempt Portfolio may purchase include,
without limitation, debt obligations issued to obtain funds for various public
purposes, including the construction of a wide range of public facilities such
as airports, bridges, highways, housing, hospitals, mass transportation, public
utilities, schools, streets, and water and sewer works. Other public purposes
for which Municipal Securities may be issued include refunding outstanding
obligations, obtaining funds for general operating expenses and obtaining funds
to loan to other public institutions and facilities.
 
Municipal Securities, such as industrial development bonds, are issued by or on
behalf of public authorities to obtain funds for purposes including privately
operated airports, housing, conventions, trade shows, ports, sports, parking or
pollution control facilities or for facilities for water, gas, electricity or
sewage and solid waste disposal. Such obligations, which may include lease
arrangements, are included within the term Municipal Securities if the interest
paid thereon qualifies as exempt from federal income tax. Other types of
industrial development bonds, the proceeds of which are used for the
construction, equipment, repair or improvement of privately operated industrial
or commercial facilities, may constitute Municipal Securities, although current
Federal tax laws place substantial limitations on the size of such issues.
 
Municipal Securities generally are classified as "general obligation" or
"revenue." General obligation notes are secured by the issuer's pledge of its
full credit and taxing power for the payment of principal and interest. Revenue
notes are payable only from the revenues derived from a particular facility or
class of facilities or, in some cases, from the proceeds of a special excise or
other specific revenue source. Industrial development bonds that are Municipal
Securities are in most cases revenue bonds and generally do not constitute the
pledge of the credit of the issuer of such bonds.
 
Examples of Municipal Securities that are issued with original maturities of one
year or less are short-term tax anticipation notes, bond anticipation notes,
revenue anticipation notes, construction loan notes, pre-refunded municipal
bonds, warrants and tax-free commercial paper.
 
                                       B-3
<PAGE>   24
 
Tax anticipation notes typically are sold to finance working capital needs of
municipalities in anticipation of receiving property taxes on a future date.
Bond anticipation notes are sold on an interim basis in anticipation of a
municipality issuing a longer term bond in the future. Revenue anticipation
notes are issued in expectation of receipt of other types of revenue such as
those available under the Federal Revenue Sharing Program. Construction loan
notes are instruments insured by the Federal Housing Administration with
permanent financing by "Fannie Mae" (the Federal National Mortgage Association)
or "Ginnie Mae" (the Government National Mortgage Association) at the end of the
project construction period. Pre-refunded municipal bonds are bonds which are
not yet refundable, but for which securities have been placed in escrow to
refund an original municipal bond issue when it becomes refundable. Tax-free
commercial paper is an unsecured promissory obligation issued or guaranteed by a
municipal issuer. The Tax-Exempt Portfolio may purchase other Municipal
Securities similar to the foregoing, which are or may become available,
including securities issued to pre-refund other outstanding obligations of
municipal issuers.
 
The Federal bankruptcy statutes relating to the adjustments of debts of
political subdivisions and authorities of states of the United States provide
that, in certain circumstances, such subdivisions or authorities may be
authorized to initiate bankruptcy proceedings without prior notice to or consent
of creditors, which proceedings could result in material adverse changes in the
rights of holders of obligations issued by such subdivisions or authorities.
 
Litigation challenging the validity under state constitutions of present systems
of financing public education has been initiated or adjudicated in a number of
states and legislation has been introduced to effect changes in public school
finances in some states. In other instances, there has been litigation
challenging the issuance of pollution control revenue bonds or the validity of
their issuance under state or Federal law that ultimately could affect the
validity of those Municipal Securities or the tax-free nature of the interest
thereon.
 
INVESTMENT MANAGER AND SHAREHOLDER SERVICES
 
INVESTMENT MANAGER. Zurich Kemper Investments, Inc. ("ZKI") is the Fund's
investment manager. ZKI is wholly owned by KFS Holding Corp. KFS Holding Corp.
is a more than 90% owned subsidiary of Zurich Holding Company of America, Inc.,
which is a wholly owned subsidiary of Zurich Insurance Company, an
internationally recognized company providing services in life and non-life
insurance, reinsurance and asset management. Pursuant to the investment
management agreement, ZKI acts as the Fund's investment adviser, manages its
investments, administers its business affairs, furnishes office facilities and
equipment, provides clerical, bookkeeping and administrative services and
permits any of its officers or employees to serve without compensation as
trustees or officers of the Fund if elected to such positions. The Fund pays the
expenses of its operations, including the fees and expenses of independent
auditors, counsel, custodian and transfer agent and the cost of share
certificates, reports and notices to shareholders, costs of calculating net
asset value, brokerage commissions or transaction costs, taxes, registration
fees, the fees and expenses of qualifying the Fund and its shares for
distribution under federal and state securities laws and membership dues in the
Investment Company Institute or any similar organization. The Fund's expenses
generally are allocated among the Portfolios on the basis of relative net assets
at the time of allocation, except that expenses directly attributable to a
particular Portfolio are charged to that Portfolio.
 
The investment management agreement provides that ZKI shall not be liable for
any error of judgment or of law, or for any loss suffered by the Fund in
connection with the matters to which the agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
ZKI in the performance of its obligations and duties, or by reason of its
reckless disregard of its obligations and duties under the agreement.
 
The investment management agreement continues in effect from year to year for
each Portfolio subject thereto so long as its continuation is approved at least
annually by (a) a majority vote of the trustees who are not parties to such
agreement or interested persons of any such party except in their capacity as
trustees of the Fund, cast in person at a meeting called for such purpose, and
(b) by the shareholders of each Portfolio subject thereto or the
 
                                       B-4
<PAGE>   25
 
Board of Trustees. If continuation is not approved for a Portfolio, the
investment management agreement nevertheless may continue in effect for any
Portfolio for which it is approved and ZKI may continue to serve as investment
manager for the Portfolio for which it is not approved to the extent permitted
by the Investment Company Act of 1940. The agreement may be terminated at any
time upon 60 days notice by either party, or by a majority vote of the
outstanding shares of a Portfolio subject thereto with respect to that
Portfolio, and will terminate automatically upon assignment. Additional
Portfolios may be subject to different agreements.
 
For the services and facilities furnished to the Money Market, Government
Securities and Tax-Exempt Portfolios, the Portfolios pay an annual investment
management fee, payable monthly, on a graduated basis of .22% of the first $500
million of combined average daily net assets of such Portfolios, .20% of the
next $500 million .175% of the next $1 billion, .16% of the next $1 billion and
 .15% of combined average daily net assets of such Portfolios over $3 billion.
ZKI has agreed to reimburse the Fund should all operating expenses of the Fund,
including the investment management fees of ZKI but excluding taxes, interest,
distribution services fees, extraordinary expenses, brokerage commissions or
transaction costs and any other properly excludable expenses, exceed the
applicable state expense limitations. The Fund believes that the most
restrictive state expense limitation currently in effect normally would require
that such operating expenses not exceed 2.5% of the first $30 million of average
daily net assets, 2% of the next $70 million and 1.5% of average daily net
assets over $100 million. The investment management fee and the expense
limitation are computed based on average daily net assets of the Portfolios and
are allocated among the Portfolios based upon the relative net assets of each.
Pursuant to the investment management agreement, the Money Market, Government
Securities and Tax-Exempt Portfolios paid ZKI fees of $677,000, $102,000 and
$26,000, respectively, for the fiscal year ended April 30, 1996; $554,000,
$114,000 and $65,000, respectively, for the fiscal year ended April 30, 1995 and
$127,000, $62,000 and $29,000, respectively, for the fiscal year ended April 30,
1994. In addition to the expense limitation described above, ZKI has agreed to
temporarily waive its management fee and absorb certain operating expenses of
the Portfolios to the extent described in the prospectus. See "Investment
Manager and Shareholder Services" in the prospectus. If the fee waiver had not
been in effect for the fiscal year ended April 30, 1996, ZKI would have received
investment management fees from the Money Market, Government Securities and
Tax-Exempt Portfolios of $891,000, $386,000 and $153,000, respectively, and
$621,000, $188,000 and $107,000, respectively for the fiscal year ended April
30, 1995. ZKI waived or absorbed operating expenses for the Money Market,
Government Securities and Tax-Exempt Portfolios of $214,000, $288,000 and
$139,000, respectively, for the fiscal year ended April 30, 1996; $173,000,
$129,000 and $82,000, respectively, during the fiscal year ended April 30, 1995
and $153,000, $108,000 and $61,000, respectively, during the fiscal year ended
April 30, 1994.
 
Certain officers or trustees of the Fund are also directors or officers of ZKI
and of KDI as indicated under "Officers and Trustees."
 
DISTRIBUTOR AND ADMINISTRATOR. Pursuant to an administration, shareholder
services and distribution agreement ("distribution agreement"), KDI serves as
primary administrator and principal underwriter for the Fund to provide
information and services for existing and potential shareholders. The
distribution agreement provides that KDI shall appoint various firms to provide
cash management services for their customers or clients through the Fund. The
firms are to provide such office space and equipment, telephone facilities,
personnel and literature distribution as is necessary or appropriate for
providing information and services to the firms' clients. For its services under
the distribution agreement, the Fund pays KDI a distribution services fee,
payable monthly, at the annual rate of .60% of average daily net assets with
respect to the Money Market and Government Securities Portfolios and .50% of
average daily net assets with respect to the Tax-Exempt Portfolio. Expenditures
by KDI on behalf of the Portfolios need not be made on the same basis that such
fees are allocated. The fees are accrued daily as an expense of the Portfolios.
 
As principal underwriter for the Fund, KDI acts as agent of the Fund in the sale
of its shares. KDI pays all its expenses under the distribution agreement
including, without limitation, services fees to firms. The Fund pays the cost
for the prospectus and shareholder reports to be set in type and printed for
existing shareholders, and KDI pays for the printing and distribution of copies
thereof used in connection with the offering of shares to prospective investors.
KDI also pays for supplementary sales literature and advertising costs.
 
                                       B-5
<PAGE>   26
 
KDI has related administration services and selling group agreements ("services
agreements") with various firms to provide cash management and other services
for Fund shareholders. Such services and assistance may include, but may not be
limited to, establishing and maintaining shareholder accounts and records,
processing purchase and redemption transactions, providing automatic investment
in Fund shares of client account balances, answering routine inquiries regarding
the Fund, assisting clients in changing account options, designations and
addresses, and such other services as may be agreed upon from time to time and
as may be permitted by applicable statute, rule or regulation. KDI also may
provide some of the above services for the Fund. KDI normally pays such firms
for services at a maximum annual rate of .60% of average daily net assets of
those accounts in the Money Market and Government Securities Portfolios that
they maintain and service and .50% of average daily net assets of those accounts
in the Tax-Exempt Portfolio that they maintain and service. KDI in its
discretion may pay certain firms additional amounts. During the fiscal year
ended April 30, 1996, the Money Market, Government Securities and Tax-Exempt
Portfolios paid distribution services fees of $2,486,000, $1,078,000 and
$356,000, respectively. Of such amounts, KDI remitted pursuant to related
services agreements $3,920,000 as service fees to firms, none of which was paid
to firms then affiliated with KDI. During the fiscal year ended April 30, 1996,
KDI incurred underwriting, distribution and administrative expenses in the
approximate amounts noted: service fees to firms ($3,920,000); advertising and
literature ($13,000); prospectus printing ($81,000); marketing and sales
expenses ($79,000) and other expenses ($0); for a total of $4,093,000. A portion
of the aforesaid marketing, sales and operating expenses could be considered
overhead expense.
 
The distribution agreement and the related services agreements with firms
constitute the Rule 12b-1 plan of the Fund. Rule 12b-1 under the Investment
Company Act of 1940 regulates the manner in which an investment company may,
directly or indirectly, bear the expenses of distributing its shares.
 
The distribution agreement continues in effect from year to year so long as such
continuance is approved at least annually by a vote of the Board of Trustees of
the Fund, including the Trustees who are not interested persons of the Fund and
who have no direct or indirect financial interest in the agreement. The
agreement automatically terminates in the event of its assignment and may be
terminated at any time without penalty by the Fund or by KDI upon six months'
notice. Termination by the Fund may be by vote of a majority of the Board of
Trustees, or a majority of the Trustees who are not interested persons of the
Fund and who have no direct or indirect financial interest in the agreement, or
a "majority of the outstanding voting securities" of the Fund as defined under
the Investment Company Act of 1940. The distribution agreement may not be
amended to increase the fee to be paid by the Fund without approval by a
majority of the outstanding voting securities of the Fund and all material
amendments must in any event be approved by the Board of Trustees in the manner
described above with respect to the continuation of the agreement. The
Portfolios of the Fund will vote separately with respect to the distribution
agreement.
 
CUSTODIAN, TRANSFER AGENT AND SHAREHOLDER SERVICE AGENT. Investors Fiduciary
Trust Company ("IFTC"), 127 West 10th Street, Kansas City, Missouri 64105, as
custodian, and State Street Bank and Trust Company, 225 Franklin Street, Boston,
Massachusetts 02110, as sub-custodian, have custody of all securities and cash
of the Fund. They attend to the collection of principal and income, and payment
for and collection of proceeds of securities bought and sold by the Fund.
Pursuant to a services agreement with IFTC, Kemper Service Company ("KSvC"), an
affiliate of ZKI, serves as "Shareholder Service Agent." IFTC receives, as
transfer agent, and pays to KSvC annual account fees of a maximum of $13 per
account plus out-of-pocket expense reimbursement. During the fiscal year ended
April 30, 1996, IFTC remitted shareholder service fees in the amount of $881,000
to KSvC as Shareholder Service Agent.
 
INDEPENDENT AUDITORS AND REPORTS TO SHAREHOLDERS. The Fund's independent
auditors, Ernst & Young LLP, 233 South Wacker Drive, Chicago, Illinois 60606,
audit and report on the Fund's annual financial statements, review certain
regulatory reports and the Fund's federal income tax return, and perform other
professional accounting, auditing, tax and advisory services when engaged to do
so by the Fund. Shareholders will receive annual audited financial statements
and semi-annual unaudited financial statements.

PORTFOLIO TRANSACTIONS
 
Portfolio transactions are undertaken principally to pursue the objective of
each Portfolio in relation to movements in the general level of interest rates,
to invest money obtained from the sale of Fund shares, to reinvest proceeds from
maturing portfolio securities and to meet redemptions of Fund shares. This may
increase or decrease the yield of a Portfolio depending upon management's
ability to correctly time and execute such transactions. Since a Portfolio's
assets will be invested in securities with short maturities, its portfolio will
turn over several times a year. Since securities with maturities of less than
one year are excluded from required portfolio turnover rate calculations, each
Portfolio's portfolio turnover rate for reporting purposes will be zero.
 
ZKI and its affiliates furnish investment management services for the Kemper
Funds and other clients including affiliated insurance companies. These entities
may share some common research and trading facilities. At times investment
decisions may be made to purchase or sell the same investment security for a
Portfolio and for one or more of the other clients of ZKI or its affiliates.
When two or more of such clients are simultaneously engaged in the purchase or
sale of the same security through the same trading facility, the transactions
are allocated as to amount and price in a manner considered equitable to each.
It is the opinion of the Board of Trustees that the benefits available because
of ZKI's organization outweigh any disadvantages that may arise from exposure to
simultaneous transactions.
 
ZKI, in effecting purchases and sales of portfolio securities for the account of
each Portfolio, will implement the Fund's policy of seeking the best execution
of orders,which includes best net prices. Consistent with this policy, orders
for portfolio transactions are placed with broker-dealer firms giving
consideration to the quality, quantity and nature of the firm's professional
services which include execution, clearance procedures, reliability and other
factors. In selecting among the firms believed to meet the criteria for handling
a particular transaction, ZKI may give consideration to those firms that provide
market, statistical and other research information to the Fund and ZKI, although
ZKI is not authorized to pay higher prices to firms that provide such services.
Any research benefits derived are available for all clients including clients of
affiliated companies. Since it is only supplementary to ZKI's own research
efforts and must be analyzed and reviewed by ZKI's staff, the receipt of
research information is not expected to materially reduce expenses. The Fund
expects that purchases and sales of portfolio securities usually will be
principal transactions. Portfolio securities will normally be purchased directly
from the issuer or from an underwriter or market maker for the securities. There
are normally no brokerage commissions paid by the Fund for such purchases.
During the last three fiscal years, the Fund paid no portfolio brokerage
commissions. Purchases from underwriters include a commission or concession paid
by the issuer to the underwriter, and purchases from dealers serving as market
makers include the spread between the bid and asked prices.
 
PURCHASE AND REDEMPTION OF SHARES
 
Shares of a Portfolio are sold at their net asset value next determined after an
order and payment are received in the form described in the Fund's prospectus.
The minimum initial investment is $1,000 and the minimum subsequent investment
is $100 but such minimum amounts may be changed at any time. The Fund may waive
the minimum for purchases by trustees, directors, officers or employees of the
Fund or ZKI and its affiliates. An investor wishing to open an account should
use the Account Information Form available from the Fund or financial services
firms. Orders for the purchase of shares that are accompanied by a check drawn
on a foreign bank (other than a check drawn on a Canadian bank in U.S. Dollars)
will not be considered in proper form and will not be processed unless and until
the Fund determines that it has received payment of the proceeds of the check.
The time required for such a determination will vary and cannot be determined in
advance.
 
The Fund may suspend the right of redemption or delay payment more than seven
days (a) during any period when the New York Stock Exchange ("Exchange") is
closed other than customary weekend and holiday closings

or during any period in which trading on the Exchange is restricted, (b) during
any period when an emergency exists as a result of which (i) disposal of a
Portfolio's investments is not reasonably practicable, or (ii) it is not
reasonably practicable for the Fund to determine the value of its net assets, or
(c) for such other periods as the Securities and Exchange Commission may by
order permit for the protection of the Fund's shareholders.
 
Although it is the Fund's present policy to redeem in cash, if the Board of
Trustees determines that a material adverse effect would be experienced by the
remaining shareholders if payment were made wholly in cash, the Fund will pay
the redemption price in whole or in part by a distribution of portfolio
securities in lieu of cash, in conformity with the applicable rules of the
Securities and Exchange Commission, taking such securities at the same value
used to determine net asset value, and selecting the securities in such manner
as the Board of Trustees deems fair and equitable. If such a distribution
occurred, shareholders receiving securities and selling them could receive less
than the redemption value of such securities and in addition could incur certain
transaction costs. Such a redemption would not be so liquid as a redemption
entirely in cash. The Fund has elected to be governed by Rule 18f-1 under the
Investment Company Act of 1940 pursuant to which the Fund is obligated to redeem
shares of a Portfolio solely in cash up to the lesser of $250,000 or 1% of the
net assets of the Portfolio during any 90-day period for any one shareholder of
record.
 
DIVIDENDS, NET ASSET VALUE AND TAXES
 
DIVIDENDS. Dividends are declared daily and paid monthly. Shareholders will
receive dividends in additional shares unless they elect to receive cash.
Dividends will be reinvested monthly in shares of the Portfolio at the net asset
value normally on the 21st day of each month if a business day, otherwise on the
next business day. The Fund will pay shareholders who redeem their entire
accounts all unpaid dividends at the time of the redemption not later than the
next dividend payment date. Upon written request to the Shareholder Service
Agent, a shareholder may elect to have Fund dividends invested without sales
charge in shares of another Kemper Mutual Fund offering this privilege at the
net asset value of such other fund. See "Special Features--Exchange Privilege"
for a list of such other Kemper Mutual Funds. To use this privilege of investing
Fund dividends in shares of another Kemper Mutual Fund, shareholders must
maintain a minimum account value of $1,000 in this Fund and must maintain a
minimum account value of $1,000 in the fund in which dividends are reinvested.
 
Each Portfolio calculates its dividends based on its daily net investment
income. For this purpose, the net investment income of the Portfolio consists of
(a) accrued interest income plus or minus amortized discount or premium
(excluding market discount for the Tax-Exempt Portfolio), (b) plus or minus all
short-term realized gains and losses on investments and (c) minus accrued
expenses allocated to the Portfolio. Expenses of the Fund are accrued each day.
While each Portfolio's investments are valued at amortized cost, there will be
no unrealized gains or losses on such investments. However, should the net asset
value of a Portfolio deviate significantly from market value, the Board of
Trustees could decide to value the investments at market value and then
unrealized gains and losses would be included in net investment income above.
 
Dividends are reinvested monthly and shareholders will receive monthly
confirmations of dividends and of purchase and redemption transactions except
that confirmations of dividend reinvestment for Individual Retirement Accounts
and other fiduciary accounts for which Investors Fiduciary Trust Company acts as
trustee will be sent quarterly.
 
NET ASSET VALUE. As described in the prospectus, each Portfolio values its
portfolio instruments at amortized cost, which does not take into account
unrealized capital gains or losses. This involves initially valuing an
instrument at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuating
interest rates on the market value of the instrument. While this method provides
certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price the Portfolio
would receive if it sold the instrument. Calculations are made to compare the
value of a Portfolio's investments valued at amortized cost with market values.
Market valuations are obtained by using actual quotations provided by market
makers, estimates of market value, or values obtained from yield data
 
                                       B-8
<PAGE>   29
 
relating to classes of money market instruments published by reputable sources
at the mean between the bid and asked prices for the instruments. If a deviation
of 1/2 of 1% or more were to occur between the net asset value per share
calculated by reference to market values and a Portfolio's $1.00 per share net
asset value, or if there were any other deviation that the Board of Trustees of
the Fund believed would result in a material dilution to shareholders or
purchasers, the Board of Trustees would promptly consider what action, if any,
should be initiated. If a Portfolio's net asset value per share (computed using
market values) declined, or were expected to decline, below $1.00 (computed
using amortized cost), the Board of Trustees of the Fund might temporarily
reduce or suspend dividend payments in an effort to maintain the net asset value
at $1.00 per share. As a result of such reduction or suspension of dividends or
other action by the Board of Trustees, an investor would receive less income
during a given period than if such a reduction or suspension had not taken
place. Such action could result in investors receiving no dividend for the
period during which they hold their shares and receiving, upon redemption, a
price per share lower than that which they paid. On the other hand, if a
Portfolio's net asset value per share (computed using market values) were to
increase, or were anticipated to increase above $1.00 (computed using amortized
cost), the Board of Trustees of the Fund might supplement dividends in an effort
to maintain the net asset value at $1.00 per share.
 
TAXES. Interest on indebtedness which is incurred to purchase or carry shares of
a mutual fund portfolio which distributes exempt-interest dividends during the
year is not deductible for Federal income tax purposes. Further, the Tax-Exempt
Portfolio may not be an appropriate investment for persons who are "substantial
users" of facilities financed by industrial development bonds held by the
Tax-Exempt Portfolio or are "related persons" to such users; such persons should
consult their tax advisers before investing in the Tax-Exempt Portfolio.
 
The "Superfund Act of 1986" (the "Superfund Act") imposes a separate tax on
corporations at a rate of 0.12 percent of the excess of such corporation's
"modified alternative minimum taxable income" over $2 million. A portion of
tax-exempt interest, including exempt-interest dividends from the Tax-Exempt
Portfolio, may be includible in modified alternative minimum taxable income.
Corporate shareholders are advised to consult their tax advisers with respect to
the consequences of the Superfund Act.
 
PERFORMANCE
 
As reflected in the prospectus, the historical performance calculation for a
Portfolio may be shown in the form of "yield," "effective yield" and, for the
Tax-Exempt Portfolio only, "tax equivalent yield." These various measures of
performance are described below. ZKI has agreed to temporarily absorb certain
operating expenses of the Portfolios to the extent described in the prospectus.
Without this expense absorption, the performance results noted herein would have
been lower.
 
Each Portfolio's yield is computed in accordance with a standardized method
prescribed by rules of the Securities and Exchange Commission. Under that
method, the yield quotation is based on a seven-day period and is computed for
each Portfolio as follows. The first calculation is net investment income per
share, which is accrued interest on portfolio securities, plus or minus
amortized discount or premium (excluding market discount for the Tax-Exempt
Portfolio), less accrued expenses. This number is then divided by the price per
share (expected to remain constant at $1.00) at the beginning of the period
("base period return"). The result is then divided by 7 and multiplied by 365
and the resulting yield figure is carried to the nearest one-hundredth of one
percent. Realized capital gains or losses and unrealized appreciation or
depreciation of investments are not included in the calculation. For the seven
day period ended April 30, 1996, the Money Market Portfolio's yield was 4.43%;
the Government Securities Portfolio's yield was 4.52%; and the Tax-Exempt
Portfolio's yield was 3.08%.
 
Each Portfolio's effective yield is determined by taking the base period return
(computed as described above) and calculating the effect of assumed compounding.
The formula for the effective yield is: (base period return +1)(3)65,7 - 1. For
the seven-day period ended April 30, 1996, the Money Market Portfolio's
effective yield was 4.53%; the Government Securities Portfolio's effective yield
was 4.62%; and the Tax-Exempt Portfolio's effective yield was 3.12%.
 
                                       B-9
<PAGE>   30
 
The tax equivalent yield of the Tax-Exempt Portfolio is computed by dividing
that portion of the Portfolio's yield (computed as described above) which is
tax-exempt by (one minus the stated Federal income tax rate) and adding the
product to that portion, if any, of the yield of the Portfolio that is not
tax-exempt. Based upon an assumed marginal Federal income tax rate of 37.1% and
the Tax-Exempt Portfolio's yield computed as described above for the seven-day
period ended April 30, 1996, the Tax-Exempt Portfolio's tax equivalent yield for
the period was 4.90%. For additional information concerning tax-exempt yields,
see "Tax-Exempt versus Taxable Yield" below.
 
Each Portfolio's yield fluctuates, and the publication of an annualized yield
quotation is not a representation as to what an investment in the Portfolio will
actually yield for any given future period. Actual yields will depend not only
on changes in interest rates on money market instruments during the period in
which the investment in the Portfolio is held, but also on such matters as
Portfolio expenses.
 
Investors have an extensive choice of money market funds and money market
deposit accounts and the information below may be useful to investors who wish
to compare the past performance of the Money Market Portfolio, the Government
Securities Portfolio and the Tax-Exempt Portfolio with that of their
competitors. Past performance cannot be a guarantee of future results.
 
As indicated in the prospectus (see "Performance"), the performance of the
Fund's Portfolios may be compared to that of other mutual funds tracked by
Lipper Analytical Services, Inc. ("Lipper"). Lipper performance calculations
include the reinvestment of all capital gain and income dividends for the
periods covered by the calculations. A Portfolio's performance also may be
compared to other money market funds as reported by IBC Financial Data, Inc.
Money Fund Report(R) or Money Market Insight(R), reporting services on money
market funds. As reported by IBC, all investment results represent total return
(annualized results for the period net of management fees and expenses) and one
year investment results would be effective annual yields assuming reinvestment
of dividends.
 
Lipper and IBC Financial Data, Inc. reported the following results for the Money
Market Portfolio and the Government Securities Portfolio.

A Portfolio's performance also may be compared on a before or after-tax basis to
various bank products, including the average rate of bank and thrift institution
money market deposit accounts, interest bearing checking accounts and 6-month
maturity certificates of deposit as reported in the BANK RATE MONITOR National
Index(TM) of 100 leading bank and thrift institutions as published by
the BANK RATE MONITOR(TM), N. Palm Beach, Florida 33408. The rates published by
the BANK RATE MONITOR National Index(TM) are averages of the personal account
rates offered on the Wednesday prior to the date of publication by 100 large
bank and thrifts in the top ten Consolidated Standard Metropolitan Statistical
Areas. With respect to money market deposit accounts and interest bearing
checking accounts, account minimums range upward from $2,000 in each
institution and compounding methods vary. Interest bearing checking accounts
generally offer unlimited checkwriting while money market deposit accounts
generally restrict the number of checks that may be written. If more than one
rate is offered, the lowest rate is used. Rates are determined by the financial
institution and are subject to change at any time specified by the institution.
Generally, the rates offered for these products take market conditions and
competitive product yields into consideration when set. Bank products represent
a taxable alternative income producing product. Bank and thrift institution
account deposits may be insured. Shareholder accounts in the Fund are not
insured. Bank passbook savings accounts share some liquidity features with
money market mutual fund accounts but they may not offer all of the features
available from a money market mutual fund, such as checkwriting. Bank passbook
savings accounts normally offer a fixed rate of interest, while the yield of
each Portfolio of the Fund fluctuates. Bank checking accounts normally do not
pay interest but share some liquidity features with money market mutual fund
accounts (e.g., the ability to write checks against the account). Bank
certificates of deposit may offer fixed or variable rates for a set term.
(Normally, a variety of terms are available.) Withdrawal of these deposits
prior to maturity normally will be subject to a penalty. In contrast, shares of
a Portfolio are redeemable at the net asset value (normally $1.00 per share)
next determined after a request is received, without charge.
 
Investors also may want to compare a Portfolio's performance to that of U.S.
Treasury bills or notes because such instruments represent alternative income
producing products. Treasury obligations are issued in selected denominations.
Rates of U.S. Treasury obligations are fixed at the time of issuance and payment
of principal and interest is backed by the full faith and credit of the U.S.
Treasury. The market value of such instruments generally will fluctuate
inversely with interest rates prior to maturity and will equal par value at
maturity. Generally, the values of obligations with shorter maturities will
fluctuate less than those with longer maturities. Each Portfolio's yield will
fluctuate. Also, while each Portfolio seeks to maintain a net asset value per
share of $1.00, there is no assurance that it will be able to do so.

TAX-EXEMPT VERSUS TAXABLE YIELD. You may want to determine which
investment--tax-exempt or taxable--will provide you with a higher after-tax
return. To determine the taxable equivalent yield, simply divide the yield from
the tax-exempt investment by the sum of [1 minus your marginal tax rate]. The
tables below are provided for your convenience in making this calculation for
selected tax-exempt yields and taxable income levels. These yields are presented
for purposes of illustration only and are not representative of any yield that
the Tax-Exempt Portfolio may generate. Both tables are based upon current law as
to the 1996 tax rate schedules.

 * This table assumes a decrease of $3.00 of itemized deductions for each $100
   of adjusted gross income over $117,950. For a married couple with adjusted
   gross income between $176,950 and $299,450 (single between $117,950 and
   $240,450), add 0.7% to the above Marginal Federal Tax Rate for each personal
   and dependency exemption. The taxable equivalent yield is the tax-exempt
   yield divided by: 100% minus the adjusted tax rate. For example, if the table
   tax rate is 37.1% and you are married with no dependents, the adjusted tax
   rate is 38.5% (37.1% + 0.7% + 0.7%). For a tax-exempt yield of 6%, the
   taxable equivalent yield is about 9.8% (6% / (100% - 38.5%)).

SPECIAL FEATURES
 
EXCHANGE PRIVILEGE.  Subject to the limitations described below, Class A Shares
(or the equivalent) of the following Kemper Mutual Funds may be exchanged for
each other at their relative net asset values: Kemper Technology Fund, Kemper
Total Return Fund, Kemper Growth Fund, Kemper Small Capitalization Equity Fund,
Kemper Income and Capital Preservation Fund, Kemper Municipal Bond Fund, Kemper
Diversified Income Fund, Kemper High Yield Fund, Kemper U.S. Government
Securities Fund, Kemper International Fund, Kemper State Tax-Free Income Series,
Kemper Adjustable Rate U.S. Government Fund, Kemper Blue Chip Fund, Kemper
Global Income Fund, Kemper Target Equity Fund (series are subject to a limited
offering period), Kemper Intermediate Municipal Bond Fund, Kemper Cash Reserves
Fund, Kemper U.S. Mortgage Fund, Kemper Short-Intermediate Government Fund,
Kemper Dreman Fund, Inc., Kemper Value+Growth Fund, Kemper Quantitative Equity
Fund, Kemper Horizon Fund and Kemper Europe Fund ("Kemper Mutual Funds") and
certain "Money Market Funds" (Kemper Money Funds, Cash Equivalent Fund,
Tax-Exempt California Money Market Fund, Cash Account Trust, Tax-Exempt New York
Money Market Fund and Investors Cash Trust). Shares of Money Market Funds and
Kemper Cash Reserves Fund that were acquired by purchase (not including shares
acquired by dividend reinvestment) are subject to the applicable sales charge on
exchange. Shares purchased by check or through an ACH transaction may not be
exchanged until they have been owned for at least 10 days. In addition,
 
                                      B-14
<PAGE>   35
 
shares of Kemper Mutual Funds, other than a Money Market Fund and Kemper Cash
Reserves Fund, acquired by exchange from another Fund may not be exchanged
thereafter until they have been owned for 15 days. A series of Kemper Target
Equity Fund will be available on exchange only during the Offering Period for
such series as described in the prospectus for such series. Cash Equivalent
Fund, Tax-Exempt California Money Market Fund, Cash Account Trust, Tax-Exempt
New York Money Market Fund and Investors Cash Trust are available on exchange
but only through a financial services firm having a services agreement with KDI
with respect to such funds. Exchanges may only be made for funds that are
available for sale in the shareholder's state of residence. Currently,
Tax-Exempt California Money Market Fund is available for sale only in California
and Tax-Exempt New York Money Market Fund is available for sale only in New
York, Connecticut, New Jersey and Pennsylvania.
 
The total value of shares being exchanged must at least equal the minimum
investment requirement of the fund into which they are being exchanged.
Exchanges are made based on relative dollar values of the shares involved in the
exchange. There is no service fee for an exchange; however, financial services
firms may charge for their services in expediting exchange transactions.
Exchanges will be effected by redemption of shares of the fund held and purchase
of shares of the other fund. For federal income tax purposes, any such exchange
constitutes a sale upon which a gain or loss may be realized, depending upon
whether the value of the shares being exchanged is more or less than the
shareholder's adjusted cost basis. Shareholders interested in exercising the
exchange privilege may obtain an exchange form and prospectuses of the other
funds from financial services firms or KDI. Exchanges also may be authorized by
telephone if the shareholder has given authorization. Once the authorization is
on file, the Shareholder Service Agent will honor requests by telephone at
1-800-231-8568 or in writing subject to the limitations on liability described
in the prospectus. Any share certificates must be deposited prior to any
exchange of such shares. During periods when it is difficult to contact the
Shareholder Service Agent by telephone, it may be difficult to implement the
telephone exchange privilege. The exchange privilege is not a right and may be
suspended, terminated or modified at any time. Except as otherwise permitted by
applicable regulation, 60 days' prior written notice of any termination or
material change will be provided.
 
SYSTEMATIC WITHDRAWAL PROGRAM. An owner of $5,000 or more of a Portfolio's
shares may provide for the payment from the owner's account of any requested
dollar amount to be paid to the owner or the owner's designated payee monthly,
quarterly, semi-annually or annually. The $5,000 minimum account size is not
applicable to Individual Retirement Accounts. Dividend distributions will be
reinvested automatically at net asset value. A sufficient number of full and
fractional shares will be redeemed to make the designated payment. Depending
upon the size of the payments requested, redemptions for the purpose of making
such payments may reduce or even exhaust the account. The program may be amended
on thirty days notice by the Fund and may be terminated at any time by the
shareholder or the Fund. Firms provide varying arrangements for their clients to
redeem Fund shares on a periodic basis. Such firms may independently establish
minimums for such services.
 
TAX-SHELTERED RETIREMENT PROGRAMS.  The Shareholder Service Agent provides
retirement plan services and documents and KDI can establish your account in any
of the following types of retirement plans:
 
- - Individual Retirement Accounts (IRAs) trusteed by Investors Fiduciary Trust
  Company ("IFTC"). This includes Simplified Employee Pension Plan (SEP) IRA
  accounts and prototype documents.
 
- - 403(b) Custodial Accounts also trusteed by IFTC. This type of plan is
  available to employees of most non-profit organizations.
 
- - Prototype money purchase pension and profit-sharing plans may be adopted by
  employers. The maximum contribution per participant is the lesser of 25% of
  compensation or $30,000.
 
Brochures describing the above plans as well as providing model defined benefit
plans, target benefit plans, 457 plans, 401(k) plans and materials for
establishing them are available from the Shareholder Service Agent upon request.
The brochures for plans trusteed by IFTC describe the current fees payable to
IFTC for its services as trustee. Investors should consult with their own tax
advisers before establishing a retirement plan.

ELECTRONIC FUNDS TRANSFER PROGRAMS. For your convenience, the Fund has
established several investment and redemption programs using electronic funds
transfer via the Automated Clearing House (ACH). There is currently no charge by
the Fund for these programs. To use these features, your financial institution
must be affiliated with an Automated Clearing House (ACH). This ACH affiliation
permits the Shareholder Service Agent to electronically transfer money between
your bank account, or employer's payroll bank in the case of Direct Deposit, and
your Fund account. Your bank's crediting policies of these transferred funds may
vary. These features may be amended or terminated at any time by the Fund.
Shareholders should contact Kemper Service Company at 1-800-621-1048 or the
financial services firm through which their account was established for more
information. These programs may not be available through some firms that
distribute shares of the Fund.
 
SHAREHOLDER RIGHTS
 
The Fund generally is not required to hold meetings of its shareholders. Under
the Agreement and Declaration of Trust of the Fund ("Declaration of Trust"),
however, shareholder meetings will be held in connection with the following
matters: (a) the election or removal of trustees if a meeting is called for such
purpose; (b) the adoption of any contract for which shareholder approval is
required by the Investment Company Act of 1940 ("1940 Act"); (c) any termination
of the Fund to the extent and as provided in the Declaration of Trust; (d) any
amendment of the Declaration of Trust (other than amendments changing the name
of the Fund or any Portfolio, establishing a Portfolio, supplying any omission,
curing any ambiguity or curing, correcting or supplementing any defective or
inconsistent provision thereof); and (e) such additional matters as may be
required by law, the Declaration of Trust, the By-laws of the Fund, or any
registration of the Fund with the Securities and Exchange Commission or any
state, or as the trustees may consider necessary or desirable. The shareholders
also would vote upon changes in fundamental investment objectives, policies or
restrictions.
 
Each trustee serves until the next meeting of shareholders, if any, called for
the purpose of electing trustees and until the election and qualification of a
successor or until such trustee sooner dies, resigns, retires or is removed by a
majority vote of the shares entitled to vote (as described below) or a majority
of the trustees. In accordance with the 1940 Act (a) the Fund will hold a
shareholder meeting for the election of trustees at such time as less than a
majority of the trustees have been elected by shareholders, and (b) if, as a
result of a vacancy in the Board of Trustees, less than two-thirds of the
trustees have been elected by the shareholders, that vacancy will be filled only
by a vote of the shareholders.
 
Trustees may be removed from office by a vote of the holders of a majority of
the outstanding shares at a meeting called for that purpose, which meeting shall
be held upon the written request of the holders of not less than 10% of the
outstanding shares. Upon the written request of ten or more shareholders who
have been such for at least six months and who hold shares constituting at least
1% of the outstanding shares of the Fund stating that such shareholders wish to
communicate with the other shareholders for the purpose of obtaining the
signatures necessary to demand a meeting to consider removal of a trustee, the
Fund has undertaken to disseminate appropriate materials at the expense of the
requesting shareholders.
 
The Declaration of Trust provides that the presence at a shareholder meeting in
person or by proxy of at least 30% of the shares entitled to vote on a matter
shall constitute a quorum. Thus, a meeting of shareholders of the Fund could
take place even if less than a majority of the shareholders were represented on
its scheduled date. Shareholders would in such a case be permitted to take
action which does not require a larger vote than a majority of a quorum, such as
the election of trustees and ratification of the selection of auditors. Some
matters requiring a larger vote under the Declaration of Trust, such as
termination or reorganization of the Fund and certain amendments of the
Declaration of Trust, would not be affected by this provision; nor would matters
which under the 1940 Act require the vote of a "majority of the outstanding
voting securities" as defined in the 1940 Act.
 
                                      B-16
<PAGE>   37
 
The Declaration of Trust specifically authorizes the Board of Trustees to
terminate the Fund (or any Portfolio or class) by notice to the shareholders
without shareholder approval.
 
Under Massachusetts law, shareholders of a Massachusetts business trust could,
under certain circumstances, be held personally liable for obligations of the
Fund. The Declaration of Trust, however, disclaims shareholder liability for
acts or obligations of the Fund and requires that notice of such disclaimer be
given in each agreement, obligation, or instrument entered into or executed by
the Fund or the trustees. Moreover, the Declaration of Trust provides for
indemnification out of Fund property for all losses and expenses of any
shareholder held personally liable for the obligations of the Fund and the Fund
will be covered by insurance which the trustees consider adequate to cover
foreseeable tort claims. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is considered by ZKI remote and not
material, since it is limited to circumstances in which a disclaimer is
inoperative and the Fund itself is unable to meet its obligations.

APPENDIX--RATINGS OF INVESTMENTS
 
                            COMMERCIAL PAPER RATINGS
 
A-1, A-2, PRIME-1, PRIME-2 AND DUFF 1, DUFF 2 COMMERCIAL PAPER RATINGS
 
Commercial paper rated by Standard & Poor's Corporation has the following
characteristics: Liquidity ratios are adequate to meet cash requirements.
Long-term senior debt is rated "A" or better. The issuer has access to at least
two additional channels of borrowing. Basic earnings and cash flow have an
upward trend with allowance made for unusual circumstances. Typically, the
issuer's industry is well established and the issuer has a strong position
within the industry. The reliability and quality of management are unquestioned.
Relative strength or weakness of the above factors determine whether the
issuer's commercial paper is rated A-1, A-2 or A-3.
 
The ratings Prime-1 and Prime-2 are the two highest commercial paper ratings
assigned by Moody's Investors Service, Inc. Among the factors considered by them
in assigning ratings are the following: (1) evaluation of the management of the
issuer; (2) economic evaluation of the issuer's industry or industries and an
appraisal of speculative-type risks which may be inherent in certain areas; (3)
evaluation of the issuer's products in relation to competition and customer
acceptance; (4) liquidity; (5) amount and quality of long-term debt; (6) trend
of earnings over a period of ten years; (7) financial strength of a parent
company and the relationships which exist with the issuer; and (8) recognition
by the management of obligations which may be present or may arise as a result
of public interest questions and preparations to meet such obligations. Relative
strength or weakness of the above factors determines whether the issuer's
commercial paper is rated Prime-1, 2 or 3.
 
The rating Duff-1 is the highest commercial paper rating assigned by Duff &
Phelps Inc. Paper rated Duff-1 is regarded as having very high certainty of
timely payment with excellent liquidity factors that are supported by ample
asset protection. Risk factors are minor. Paper rated Duff-2 is regarded as
having good certainty of timely payment, good access to capital markets and
sound liquidity factors and company fundamentals. Risk factors are small.
 
MIG-1 AND MIG-2 MUNICIPAL NOTES
 
Moody's Investors Service, Inc.'s ratings for state and municipal notes and
other short-term loans will be designated Moody's Investment Grade (MIG). This
distinction is in recognition of the differences between short-term credit risk
and long-term risk. Factors affecting the liquidity of the borrower are
uppermost in importance in short-term borrowing, while various factors of the
first importance in bond risk are of lesser importance in the short run. Loans
designated MIG-1 are of the best quality, enjoying strong protection from
established cash flows of funds for their servicing or from established and
broad-based access to the market for refinancing, or both. Loans designated
MIG-2 are of high quality, with margins of protection ample although not so

AAA. This is the highest rating assigned by Standard & Poor's Corporation to a
debt obligation and indicates an extremely strong capacity to pay principal and
interest.
 
AA. Bonds rated AA also qualify as high-quality debt obligations. Capacity to
pay principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.

                  MOODY'S INVESTORS SERVICE, INC. BOND RATINGS
 
AAA. Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as
"gilt-edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
AA. Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be of greater amplitude or there may be other elements present which make
the long term risks appear somewhat larger than in Aaa securities.
 
                        DUFF & PHELP'S INC. BOND RATINGS
 
AAA--Highest credit quality. The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.
 
AA--High credit quality. Protection factors are strong. Risk is modest but may
vary slightly from time to time because of economic conditions.
