------------------
The above funds currently offer four classes of shares to provide investors with
different purchasing options. These are Class A, Class B and Class C shares,
which are described in the funds' prospectus, and Class I shares, which are
described in the prospectus as supplemented hereby. When placing purchase
orders, investors must specify whether the order is for Class A, Class B, Class
C or Class I shares.
Class I shares are available for purchase exclusively by the following
categories of institutional investors: (1) tax-exempt retirement plans (Profit
Sharing, 401(k), Money Purchase Pension and Defined Benefit Plans) of Scudder
Kemper Investments, Inc. ("Scudder Kemper") and its affiliates and rollover
accounts from those plans; (2) the following investment advisory clients of
Scudder Kemper and its investment advisory affiliates that invest at least $1
million in a Fund: unaffiliated benefit plans, such as qualified retirement
plans (other than individual retirement accounts and self-directed retirement
plans); unaffiliated banks and insurance companies purchasing for their own
accounts; and endowment funds of unaffiliated non-profit organizations; (3)
investment-only accounts for large qualified plans, with at least $50 million in
total plan assets or at least 1000 participants; (4) trust and fiduciary
accounts of trust companies and bank trust departments providing fee-based
advisory services that invest at least $1 million in a Fund on behalf of each
trust; (5) policy holders under Zurich-American Insurance Group's collateral
investment program investing at least $200,000 in a Fund; and (6) investment
companies managed by Scudder Kemper that invest primarily in other investment
companies.

Class I shares currently are available for purchase only from Kemper
Distributors, Inc. ("KDI"), principal underwriter for the Funds, and, in the
case of category 4 above, selected dealers authorized by KDI. Share certificates
are not available for Class I shares.
The primary distinctions among the classes of each Fund's shares lie in their
initial and contingent deferred sales charge schedules and in their ongoing
expenses, including asset-based sales charges in the form of Rule 12b-1
distribution fees. Class I shares are offered at net asset value without an
initial sales charge and are not subject to a contingent deferred sales charge
or a Rule 12b-1 distribution fee. Also, there is no administrative services fee
charged to Class I shares. As a result of the relatively lower expenses for
Class I shares, the level of income dividends per share (as a percentage of net
asset value) and, therefore, the overall investment return, typically will be
higher for Class I shares than for Class A, Class B and Class C shares.
The following information supplements the indicated sections of the prospectus.
Past Performance
The charts and tables contained in the accompanying prospectus provide some
indication of the risks of investing in the funds by illustrating how the funds
have performed from year to year, and comparing this information to a broad
measure of market performance. Of course, past performance is not necessarily an
indication of future performance. Additional financial information for those
funds which currently have Class I shares outstanding is set forth below.

Example
This example is to help you compare the cost of investing in a fund with the
cost of investing in other mutual funds.
This example illustrates the impact of the above fees and expenses on an account
with an initial investment of $10,000, based on the expenses shown above. It
assumes a 5% annual return, the reinvestment of all dividends and distributions
and "annual fund operating expenses" remaining the same each year. The example
is hypothetical: actual fund expenses and return vary from year to year, and may
be higher or lower than those shown.

any other "Kemper Mutual Fund" listed in the prospectus. Conversely,
shareholders of Zurich Money Funds -- Zurich Money Market Fund who have
