How The Funds Work

These funds invest mainly in bonds and other types of debt securities.

Taken as a group, they represent a spectrum of approaches to investing for
income, from a conservative approach that emphasizes preservation of capital to
a more aggressive (and more risky) approach that focuses on higher income and
total return. Each fund has its own objective.

Remember that mutual funds are investments, not bank deposits. They're not
insured or guaranteed by the FDIC or any other government agency. Their share
prices will go up and down, so be aware that you could lose money.

Kemper
High Yield Fund

FUND GOAL The fund seeks the highest level of current income obtainable
from a diversified portfolio of fixed income securities which the fund's
investment manager considers consistent with reasonable risk. As a secondary
objective, the fund will seek capital gain where consistent with its primary
objective.

                           2 - Kemper High Yield Fund
<PAGE>

The Fund's Main Strategy

The fund invests mainly in lower rated, higher yielding corporate bonds, often
called junk bonds. Generally, most are from U.S. issuers, but up to 25% of total
assets could be in bonds from foreign issuers.

In deciding which securities to buy and sell to achieve income and capital
appreciation, the portfolio managers analyze securities to determine which
appear to offer reasonable risk compared to their potential return. To do this,
they rely on extensive independent analysis, favoring the bonds of companies
whose credit is gaining strength or whom they believe are unlikely to default.

Based on their analysis of economic and market trends, the managers may favor
bonds from different segments of the economy at different times, while still
maintaining variety in terms of the types of bonds, companies and industries
represented. For example, the managers typically favor subordinated debt (which
has higher risks and may pay higher returns), but may emphasize senior debt if
they expect an economic slowdown.

The managers may adjust the duration (a measure of sensitivity to interest rate
movements) of the fund's portfolio, depending on their outlook for interest
rates.

[ICON]--------------------------------------------------------------------------

CREDIT QUALITY POLICIES

This fund normally invests at least 65% of total assets in junk bonds, which are
those below the fourth credit grade (i.e., grade BB/Ba and below). Compared to
investment-grade bonds, junk bonds may pay higher yields and have higher
volatility and higher risk of default on payments.

The Main Risks Of Investing In The Fund

There are several risk factors that could reduce the yield you get from the
fund, cause you to lose money or make the fund perform less well than other
investments.

For this fund, one of the main factors is the economy. Because the companies
that issue high yield bonds may be in uncertain financial health, the prices of
their bonds can be more vulnerable to bad economic news or even the expectation
of bad news, than investment-grade bonds. This may affect a company, an industry
or the high yield market as a whole. In some cases, bonds may decline in credit
quality or go into default. This risk is higher with foreign bonds.

Another factor is market interest rates. A rise in interest rates generally
means a fall in bond prices -- and, in turn, a fall in the value of your
investment. An increase in the portfolio's duration could make the fund more
sensitive to this risk.

Because the economy has a strong impact on corporate bond performance, the fund
will tend to perform less well than other types of bond funds when the economy
is weak. To the extent that the fund emphasizes bonds from any given industry,
it could be hurt if that industry does not do well.

Other factors that could affect performance include:

o    the managers could be wrong in their analysis of economic trends, issuers,
     industries or other matters

o    some bonds could be paid off earlier than expected, which could hurt the
     fund's performance

o    currency fluctuations could cause foreign investments to lose value

o    at times, it could be hard to value some investments or to get an
     attractive price for them

Performance

The bar chart shows how the total returns for the fund's Class A shares have
varied from year to year, which may give some idea of risk. The chart doesn't
reflect sales loads; if it did, returns would be lower. The table shows how the
fund's returns over different periods average out.

For context, the table has a broad-based market index (which, unlike the fund,
has no fees or expenses). All figures on this page assume reinvestment of
dividends and distributions. As always, past performance is no guarantee of
future results.

     of 1.00% if redeemed within one year of purchase and 0.50% if redeemed
     during the second year following purchase.

Based on the figures above, this example is designed to help you compare the
expenses of each share class to those of other funds. The example assumes
operating expenses remain the same and that you invested $10,000, earned 5%
annual returns and reinvested all dividends and distributions. This is only an
example; actual expenses will be different.

Kemper
High Yield
Opportunity Fund

FUND GOAL The fund seeks total return through high current income and
capital appreciation.


                     14 - Kemper High Yield Opportunity Fund
<PAGE>


The Fund's Main Strategy

The fund invests mainly in lower rated, higher yielding corporate bonds, often
called junk bonds. Generally, most are from U.S. issuers, but up to 25% of total
assets could be in bonds of foreign issuers. To enhance total return, the fund
may invest up to 20% of total assets in common stocks and other equities,
including preferred stocks, convertible securities and real estate investment
trusts (REITs).

In deciding which securities to buy and sell, the portfolio managers rely on
extensive independent analysis, favoring the bonds of companies whose credit is
gaining strength or whom they believe are unlikely to default. The managers also
seek to take advantage of special opportunities by investing in stocks of
high-yield issuers, including initial public offerings of stock (IPOs).

Based on their analysis of economic and market trends, the managers may favor
bonds from different segments of the economy at different times, while still
maintaining variety in terms of the companies and industries represented. For
example, the managers typically favor subordinated debt (which has higher risks
and may pay higher returns), but may emphasize senior debt if the managers
expect an economic slowdown.

The managers may adjust the duration (a measure of sensitivity to interest rate
movements) of the fund's portfolio, depending on their outlook for interest
rates.

[ICON]--------------------------------------------------------------------------
          CREDIT QUALITY POLICIES

This fund normally invests primarily in junk bonds, which are those below the
fourth credit grade (i.e., grade BB/Ba and below). Compared to investment-grade
bonds, junk bonds may pay higher yields and have higher volatility and higher
risk of default on payments.

The Main Risks Of Investing In The Fund

There are several risk factors that could reduce the yield you get from the
fund, cause you to lose money or make the fund perform less well than other
investments.

For this fund, one of the main factors is the economy. Because the companies
that issue high yield bonds may be in uncertain financial health, the prices of
their bonds (and stocks) can be more vulnerable to bad economic news, or even
the expectation of bad news, than investment-grade bonds. This may affect a
company, an industry or the high yield market as a whole. In some cases, bonds
may decline in credit quality or go into default. This risk is higher with
foreign bonds.

Another factor is market interest rates. A rise in interest rates generally
means a fall in bond prices -- and, in turn, a fall in the value of your
investment. An increase in the portfolio's duration could make the fund more
sensitive to this risk.

Because the economy affects corporate bond performance, the fund will tend to
perform less well than other types of bond funds when the economy is weak. Also,
to the extent that the fund emphasizes bonds from any given industry, it could
be hurt if that industry does not do well.

Other factors that could affect performance include:

o    the managers could be wrong in their analysis of economic trends, issuers,
     industries or other matters

o    some bonds could be paid off earlier than expected, which could hurt the
     fund's performance

o    currency fluctuations could cause foreign investments to lose value

o    at times, it could be hard to value some investments or to get an
     attractive price for them

Income And Capital
Preservation Fund

FUND GOAL The fund seeks as high a level of current income as is
consistent with reasonable risk, preservation of capital and ready marketability
of its portfolio by investing primarily in a diversified portfolio of
investment-grade debt securities.

                20 - Kemper Income and Capital Preservation Fund

<PAGE>


The Fund's Main Strategy

The fund can buy many types of income-producing securities, among them corporate
bonds, U.S. government and agency bonds and mortgage- and asset-backed
securities. Generally, most are from U.S. issuers, but up to 25% of total assets
could be in bonds from foreign issuers.

In deciding which securities to buy and sell, the portfolio manager uses
independent analysis to look for bonds of companies whose fundamental business
prospects and cash flows are expected to improve. The manager also considers
valuation, preferring those bonds that appear attractively priced in comparison
to similar issues.

Based on the analysis of economic and market trends, the manager may favor bonds
from different segments of the economy at different times, while still
maintaining variety in terms of the companies and industries represented.

Although the manager may adjust the duration (a measure of sensitivity to
interest rate movements) of the fund's portfolio, he generally intends to keep
it between four and six years.

          CREDIT QUALITY POLICIES

This fund normally invests at least 80% of total assets in bonds of the top four
grades of credit quality. The fund could invest up to 20 percent of total assets
in junk bonds (i.e., grade BB/Ba and below). Compared to investment-grade bonds,
junk bonds may pay higher yields and have higher volatility and higher risk of
default on payments of interest or principal.

The Main Risks Of Investing In The Fund

There are several factors that could reduce the yield you get from the fund,
cause you to lose money or make the fund perform less well than other
investments.

As with most bond funds, the most important factor is market interest rates. A
rise in interest rates generally means a fall in bond prices -- and, in turn, a
fall in the value of your investment. Changes in interest rates will also affect
the fund's yield: when rates fall, fund yield tends to fall as well.

Because the economy affects corporate bond performance, the fund will tend to
perform less well than other types of bond funds when the economy is weak. Also,
to the extent that the fund emphasizes bonds from any given industry, it could
be hurt if that industry does not do well.

Other factors that could affect performance include:

o    the manager could be wrong in the analysis of economic trends, issuers,
     industries or other matters

o    a bond could decline in credit quality or go into default; this risk is
     greater with lower rated bonds

o    some bonds could be paid off earlier than expected, which could hurt the
     fund's performance

o    currency fluctuations could cause foreign investments to lose value

o    at times, it could be hard to value some investments or to get an
     attractive price for them

<PAGE>

The Fund's Main Strategy

The fund invests mainly in U.S. government securities with an emphasis on
mortgage-backed securities. Other securities in which the fund may invest
include other mortgage-backed securities such as Ginnie Maes, U.S. Treasuries
and other securities issued by the U.S. government, its agencies or
instrumentalities. The fund may also invest in corporate bonds, including
asset-backed securities.

In deciding which types of government bonds to buy and sell, the portfolio
managers first consider the relative attractiveness of Treasuries compared to
other U.S. government and agency securities and determine allocations for each.
Their decisions are generally based on a number of factors, including interest
rate outlooks and changes in supply and demand within the bond market.

In choosing corporate bonds, the managers use independent analysis to look for
established companies with histories of dependable dividend payments and stable
or growing prices.

Although the managers may adjust the fund's dollar-weighted average maturity
(the effective maturity of the fund's portfolio), they generally intend to keep
it below three years.

[ICON]--------------------------------------------------------------------------
          CREDIT QUALITY POLICIES

This fund normally invests at least 65% of total assets in securities issued by
the U.S. Government, its agencies or instrumentalities.

The fund could invest up to 35% of total assets in non-U.S. government
investment-grade bonds, and 10% of total assets in junk bonds (i.e., grade BB/Ba
and below).

The Main Risks Of Investing In The Fund

There are several factors that could reduce the yield you get from the fund,
cause you to lose money or make the fund perform less well than other
investments.

As with most bond funds, one of the most important factors is market interest
rates. A rise in interest rates generally means a fall in bond prices -- and, in
turn, a fall in the value of your investment. The fund's relatively short
maturity should reduce the effect of this risk, but won't eliminate it. Changes
in interest rates will also affect the fund's yield: when rates fall, fund yield
tends to fall as well.

Some securities issued by U.S. government agencies or instrumentalities are
supported only by the credit of that agency or instrumentality, while other
securities have 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. The full faith and credit guarantee of the U.S. government doesn't
protect the fund against market-driven declines in the prices or yields of these
securities, nor does it apply to shares of the fund itself.

Mortgage- and asset-backed securities carry additional risks and may be more
volatile than many other types of debt securities. Any unexpected behavior in
interest rates could hurt the performance of these securities. For example, a
large fall in interest rates could cause these securities to be paid off earlier
than expected, forcing the fund to reinvest the money at a lower rate. In
addition, if interest rates rise or stay high, these securities could be paid
off later than expected, forcing the fund to endure low yields. The result for
the fund could be an increase in the volatility of its share price and yield.

Other factors that could affect performance include:

o    the managers could be wrong in their analysis of economic trends, issuers,
     industries or other matters

o    a bond could decline in credit quality or go into default; this risk is
     greater with junk and foreign bonds

o    at times, it could be hard to value some investments or to get an
     attractive price for them

This fund may make sense for investors seeking higher income than a money fund
and can accept some fluctuations in the value of their principal.

Performance

The bar chart shows how the total returns for the fund's Class A shares have
varied from year to year, which may give some idea of risk. The chart doesn't
reflect sales loads; if it did, returns would be lower. The table shows how the
fund's returns over different periods average out.

For context, the table has two broad-based market indices (which, unlike the
fund, has no fees or expenses). All figures on this page assume reinvestment of
dividends and distributions. As always, past performance is no guarantee of
future results.

The Fund's Main Strategy

The fund invests principally in U.S. government securities of any maturity,
focusing on Ginnie Maes. The fund may invest in other mortgage-backed securities
and other U.S. government securities including U.S. Treasuries and other
securities issued by the U.S. government, its agencies or instrumentalities.

decisions are generally based on a number of factors, including interest rate
outlooks and changes in supply and demand within the bond market.

In choosing individual bonds, the managers review each bond's fundamentals,
compare the yields of shorter maturity bonds to those of longer maturity bonds
and use technical analysis to project prepayment rates and other factors that
could affect a bond's attractiveness.

The managers may adjust the duration (a measure of sensitivity to interest rate
movements) of the fund's portfolio, depending on their outlook for interest
rates.

The Fund's Main Strategy

The fund invests mainly in bonds issued by U.S. and foreign corporations and
governments. The fund may invest up to 50% of total assets in foreign bonds. The
fund may also invest in emerging markets securities.

In deciding which types of securities to buy and sell, the portfolio managers
evaluate each major type of security the fund invests in -- U.S. junk bonds,
investment-grade corporate bonds, emerging markets securities, foreign
government bonds and U.S. government and agency securities. The managers
typically consider a number of factors, including the relative attractiveness of
different types of securities, the potential impact of interest rate movements,
the outlook for various types of foreign bonds (including currency
considerations) and the relative yields and risks of bonds of various
maturities.

The managers may shift the proportions of the fund's holdings, favoring
different types of securities at different times, while still maintaining
variety in terms of the companies and industries represented.

The managers may adjust the duration (a measure of sensitivity to interest rate
movements) of the fund's portfolio, depending on their outlook for interest
rates.

[ICON]--------------------------------------------------------------------------
          CREDIT QUALITY POLICIES

The credit quality of the fund's investments may vary; the fund may invest up to
100% of total assets in either investment-grade bonds or in junk bonds, which
are those below the fourth credit grade (i.e., grade BB/Ba and below). Compared
to investment-grade bonds, junk bonds may pay higher yields and have higher
volatility and higher risk of default on payments of interest or principal.

The Main Risks Of Investing In The Fund

There are several factors that could reduce the yield you get from the fund,
cause you to lose money, or make the fund perform less well than other
investments.

For this fund, the main risk factor will vary depending on the fund's weighting
of various types of securities. To the extent that it invests in junk bonds, one
of the main risk factors is the economy. Because the companies that issue high
yield bonds may be in uncertain financial health, the prices of their bonds can
be more vulnerable to bad economic news or even the expectation of bad news,
than investment-grade bonds. In some cases, bonds may decline in credit quality
or go into default. Also, negative corporate news may have a significant impact
on individual bond prices.

To the extent that the fund invests in higher quality bonds, a major factor is
market interest rates. A rise in interest rates generally means a fall in bond
prices -- and, in turn, a fall in the value of your investment. An increase in
the portfolio's duration could make the fund more sensitive to this risk.

Foreign securities tend to be more volatile than their U.S. counterparts, for
reasons ranging from political and economic uncertainties to a higher risk that
essential information may be incomplete or wrong. To the extent the fund
emphasizes emerging markets where these risks are greater, it takes on greater
risk.

Other factors that could affect performance include:

o    the managers could be wrong in their analysis of economic trends, issuers,
     industries or other matters

o    currency fluctuations could cause foreign investments to lose value

o    some bonds could be paid off earlier than expected, which could hurt the
     fund's performance

o    at times, it could be hard to value some investments or to get an
     attractive price for them

U.S. Mortgage Fund

FUND GOAL The fund seeks to provide maximum current return from U.S.
government securities.


                         44 - Kemper U.S. Mortgage Fund

<PAGE>

The Fund's Main Strategy

The fund invests primarily in U.S. government securities, mainly mortgage-backed
securities issued by U.S. government agencies. These include securities issued
by Ginnie Mae, Fannie Mae and Freddie Mac. The fund can also invest in U.S.
Treasury securities.

In deciding which types of securities to buy and sell, the portfolio managers
first consider the relative attractiveness of mortgage-backed securities
compared to U.S. Treasuries and decide on allocations for each. Their decisions
are generally based on a number of factors, including changes in supply and
demand within the bond market.

In choosing individual bonds, the managers review each bond's fundamentals,
compare the yields of shorter maturity bonds to those of longer maturity bonds
and use technical analysis to project prepayment rates and other factors that
could affect a bond's attractiveness.

The managers may adjust the duration (a measure of sensitivity to interest rate
movements) of the fund's portfolio, depending on their outlook for interest
rates.

[ICON]--------------------------------------------------------------------------
          CREDIT QUALITY POLICIES

This fund normally invests at least 65% of total assets in mortgage-backed
securities issued by the U.S. government, its agencies or instrumentalities.
These securities are generally considered to be among the very highest quality
securities.

<PAGE>


The Main Risks Of Investing In The Fund

There are several factors that could reduce the yield you get from the fund,
cause you to lose money or make the fund perform less well than other
investments.

As with most bond funds, one of the most important factors is market interest
rates. A rise in interest rates generally means a fall in bond prices -- and, in
turn, a fall in the value of your investment. An increase in the portfolio's
duration could make the fund more sensitive to this risk.

Some securities issued by U.S. government agencies or instrumentalities are
supported only by the credit of that agency or instrumentality, while other
securities have 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. The full faith and credit guarantee of the U.S. government doesn't
protect the fund against market-driven declines in the prices or yields of these
securities, nor does it apply to shares of the fund itself.

Mortgage-backed securities carry additional risks and may be more volatile than
many other types of debt securities. Any unexpected behavior in interest rates
could hurt the performance of these securities. For example, a large fall in
interest rates could cause these securities to be paid off earlier than
expected, forcing the fund to reinvest the money at a lower rate. Another
example: if interest rates rise or stay high, these securities could be paid off
later than expected, forcing the fund to endure low yields. The result for the
fund could be an increase in the volatility of its share price and yield.

Other factors that could affect performance include:

o    the managers could be wrong in their analysis of economic trends, issuers
     or other matters

o    at times, it could be hard to value some investments or to get an
     attractive price for them

Based on the figures above, this example is designed to help you compare the
expenses of each share class to those of other funds. The example assumes
operating expenses remain the same and that you invested $10,000, earned 5%
annual returns and reinvested all dividends and distributions. This is only an
example; actual expenses will be different.

Other Policies And Risks

While the previous pages describe the main points of each fund's strategy and
risks, there are a few other issues to know about:

o    Although major changes tend to be infrequent, each fund's Board could
     change that fund's investment goal without seeking shareholder approval.

o    These funds may trade more securities than some other bond funds. This
     could raise transaction costs (and lower performance) and could mean higher
     taxable distributions.

o    As a temporary defensive measure, any of these funds could shift up to 100%
     of assets into investments such as money market securities. This could
     prevent losses, but would mean that the fund would not be pursuing its
     goal.

o    Scudder Kemper establishes a security's credit quality when it buys the
     security, using independent ratings or, for unrated securities, its own
     credit determination. When ratings don't agree, a fund may use the higher
     rating. If a security's credit quality falls, the advisor will determine
     whether selling it would be in the shareholders' best interests.

o    Although the managers are permitted to use various types of derivatives
     (contracts whose value is based on, for example, indices, currencies or
     securities), the managers don't intend to use them as principal
     investments. With derivatives, there is a risk that they could produce
     disproportionate losses.

Keep in mind that there is no assurance that any mutual fund will achieve its
goal.

Year 2000 and euro readiness

Like all mutual funds, these funds could be affected by the inability of some
computer systems to recognize the year 2000. Also, those funds permitted to
invest in foreign securities could be affected by accounting differences,
changes in tax treatment or other issues related to the conversion of certain
European currencies into the euro, which is already underway. Scudder Kemper has
readiness programs designed to address these problems, and has researched the
readiness of suppliers and business partners as well as issuers of securities
the funds own. Still, there's some risk that one or both of these problems could
materially affect a fund's operations (such as its ability to calculate net
asset value and to handle purchases and redemptions), its investments or
securities markets in general.

Financial Highlights

These tables are designed to help you understand each fund's financial
performance in recent years. The figures in the first part of each table are for
a single share. The total return figures represent the percentage that an
investor in a particular fund would have earned (or lost), assuming all
dividends and distributions were reinvested. This information has been audited
by Ernst & Young LLP, whose report, along with each fund's financial statements,
is included in that fund's annual report (see "Shareholder reports" on the back
cover).

          Investing In The Funds

     The following pages tell you about many of the services, choices and
benefits of being a Kemper Funds shareholder. You'll also find information on
how to check the status of your account using the method that's most convenient
for you.

     You can find out more about the topics covered here by speaking with your
financial representative or a representative of your workplace retirement plan
or other investment provider.

Choosing A Share Class

In this prospectus, there are three share classes for each fund. Each class has
its own fees and expenses, offering you a choice of cost structures.

Before you invest, take a moment to look over the characteristics of each share
class, so that you can be sure to choose the class that's right for you. You may
want to ask your financial representative to help you with this decision.

We describe each share class in detail on the following pages. But first, you
may want to look at the table below, which gives you a brief comparison of the
main features of each class.


- ------------------------------------   -----------------------------------------
Classes and features                    Points to help you compare
- ------------------------------------   -----------------------------------------

Class A

o Sales charges of up to 4.50%,         o Some investors may be able to
  charged when you buy shares             reduce or eliminate their sales
                                          charges; see next page
o In most cases, no charges when you
  sell shares                           o Total annual expenses are lower
                                          than those for Class B or Class C
o No distribution fee

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

Class B

o No charges when you buy shares         o The deferred sales charge rate falls
                                           to zero after six years
o Deferred sales charge of up to
  4.00%, charged when you sell shares    o Shares automatically convert to
  you bought within the last six years     Class A after six years, which means
                                           lower annual expenses going forward
o 0.75% distribution fee

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

Class C

o No charges when you buy shares        o The deferred sales charge rate is
                                          lower, but your shares never convert
o Deferred sales charge of 1.00%,         to Class A, so annual expenses
  charged when you sell shares you        remain higher
  bought within the last year

o 0.75% distribution fee

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

                          69 - Choosing A Share Class

<PAGE>


You may be able to lower your Class A sales charges if:

o    you plan to invest at least $100,000 over the next 24 months ("letter of
     intent")

o    the amount of Kemper shares you already own (including shares in certain
     other Kemper funds) plus the amount you're investing now is at least
     $100,000 ("cumulative discount")

o    you are investing a total of $100,000 or more in several Kemper funds at
     once ("combined purchases")

The point of these three features is to let you count investments made at other
times for purposes of calculating your present sales charge. Any time you can
use the privileges to "move" your investment into a lower sales charge category
in the table above, it's generally beneficial for you to do so. You can take
advantage of these methods by filling in the appropriate sections of your
application or by speaking with your financial representative.


                          70 - Choosing A Share Class

<PAGE>


You may be able to buy Class A shares without sales charges when you are:

o    reinvesting dividends or distributions

o    investing through certain workplace retirement plans

o    participating in an investment advisory program under which you pay a fee
     to an investment advisor or other firm for portfolio management services

There are a number of additional provisions that apply in order to be eligible
for a sales charge waiver. The fund may waive the sales charges for investors in
other situations as well. Your financial representative or Kemper can answer
your questions and help you determine if you are eligible.

If you're investing $1 million or more, either as a lump sum or through one of
the sales charge reduction features described on the previous page, you may be
eligible to buy Class A shares without sales charges. However, you may be
charged a contingent deferred sales charge (CDSC) of 1.00% on any shares you
sell within the first year of owning them, and a similar charge of 0.50% on
shares you sell within the second year of owning them.


THE FOLLOWING SIDEBAR TEXT APPEARS NEXT TO THE PRECEDING PARAGRAPHS.

Class A shares may make sense for long-term investors, especially those who are
eligible for reduced or eliminated sales charges.

<PAGE>


Class B shares

With Class B shares, you pay no up-front sales charges to the fund. Class B
shares do have a 12b-1 plan, under which a distribution fee of 0.75% is deducted
from fund assets each year. This means the annual expenses for Class B shares
are somewhat higher (and their performance correspondingly lower) compared to
Class A shares, which don't have a 12b-1 fee. After six years, Class B shares
automatically convert to Class A, which has the effect of lowering the annual
expenses from the seventh year on.

Class B shares have a contingent deferred sales charge (CDSC). This charge
declines over the years you own shares, and disappears completely after six
years of ownership. But for any shares you sell within those six years, you may
be charged as follows:

Year after you bought shares   CDSC on shares you sell
- -----------------------------------------------------------
First year                     4.00%
- -----------------------------------------------------------
Second or third year           3.00
- -----------------------------------------------------------
Fourth or fifth year           2.00
- -----------------------------------------------------------
Sixth year                     1.00
- -----------------------------------------------------------
Seven year and later           None (automatic conversion
                               to Class A)
- -----------------------------------------------------------

This CDSC is waived under certain circumstances (see "Policies You Should Know
About"). Your financial representative or Kemper can answer your questions and
help you determine if you're eligible.

While Class B shares don't have any front-end sales charges, their higher annual
expenses (due to 12b-1 fees) mean that over the years you could end up paying
more than the equivalent of the maximum allowable front-end sales charge.

THE FOLLOWING SIDEBAR TEXT APPEARS NEXT TO THE PRECEDING PARAGRAPHS.

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

Class B shares can make sense for long-term investors who would prefer to see
all of their investment go to work right away, and can accept somewhat higher
annual expenses in exchange.

Class C shares

Like Class B shares, Class C shares have no up-front sales charges and have a
12b-1 plan under which a distribution fee of 0.75% is deducted from fund assets
each year. Because of this fee, the annual expenses for Class C shares are
similar to those of Class B shares, but higher than those for Class A shares
(and the performance of Class C shares is correspondingly lower than that of
Class A).

Unlike Class B shares, Class C shares do NOT automatically convert to Class A
after six years, so they continue to have higher annual expenses.

Class C shares have a contingent deferred sales charge (CDSC), but only on
shares you sell within one year of buying them:


Year after you bought shares   CDSC on shares you sell
- -------------------------------------------------------
First year                     1.00%
- -------------------------------------------------------
Second year and later          None
- -------------------------------------------------------

This CDSC is waived under certain circumstances (see "Policies You Should Know
About"). Your financial representative or Kemper can answer your questions and
help you determine if you're eligible.

While Class C shares don't have any front-end sales charges, their higher annual
expenses (due to 12b-1 fees) mean that over the years you could end up paying
more than the equivalent of the maximum allowable front-end sales charge.


THE FOLLOWING SIDEBAR TEXT APPEARS NEXT TO THE PRECEDING PARAGRAPHS.

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

Class C shares may appeal to investors who plan to sell some or all shares
within six years of buying them, or who aren't certain of their investment time
horizon.

Policies You Should Know About

Along with the instructions on the previous pages, the policies below may affect
you as a shareholder.

If you are investing through an investment provider, check the materials you
received from them. As a general rule, you should follow the information in
those materials wherever it contradicts the information given here. Please note
that an investment provider may charge its own fees.

Policies about transactions

The funds are open for business each day the New York Stock Exchange is open.
Each fund calculates its share price every business day, as of the close of
regular trading on the Exchange (typically 3 p.m. Central time, but sometimes
earlier, as in the case of scheduled half-day trading or unscheduled suspensions
of trading).

You can place an order to buy or sell shares at any time. Once your order is
received by Kemper Service Company, and they have determined that it is a "good
order," it will be processed at the next share price calculated.

Because orders placed through investment providers must be forwarded to Kemper
Service Company before they can be processed, you'll need to allow extra time. A
representative of your investment provider should be able to tell you when your
order will be processed.

KemperACCESS, the Kemper Automated Information Line, is available 24 hours a day
by calling (800) 972-3060. You can use Kemper ACCESS to get information on
Kemper funds generally and on accounts held directly at Kemper. You can also use
it to make exchanges and sell shares.

                      76 - Policies You Should Know About

<PAGE>


EXPRESS-Transfer lets you set up a link between a Kemper account and a bank
account. Once this link is in place, you can move money between the two with a
phone call. You'll need to make sure your bank has Automated Clearing House
(ACH) services. Transactions take two to three days to be completed, and there
is a $100 minimum. To set up EXPRESS-Transfer on a new account, see the account
application; to add it to an existing account, call (800) 621-1048.

Share certificates are available on written request. However, we don't recommend
them unless you want them for a specific purpose, because they can only be sold
by mailing them in, and if they're ever lost they're difficult and expensive to
replace.

When you call us to sell shares, we may record the call, ask you for certain
information or take other steps designed to prevent fraudulent orders. It's
important to understand that, with respect to certain pre-authorized
transactions, as long as we take reasonable steps to ensure that an order
appears genuine, we are not responsible for any losses that may occur.

When you ask us to send or receive a wire, please note that while we don't
charge a fee to send or receive wires, it's possible that your bank may do so.
Wire transactions are completed within 24 hours. The funds can only send or
accept wires of $1,000 or more.

Exchanges among Kemper funds are an option for most shareholders. Exchanges are
a shareholder privilege, not a right: we may reject any exchange order,
particularly when there appears to be a pattern of "market timing" or other
frequent purchases and sales. We may also reject or limit purchase orders, for
these or other reasons.


THE FOLLOWING SIDEBAR TEXT APPEARS NEXT TO THE PRECEDING PARAGRAPHS.

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

The Kemper Web site can be a valuable resource for shareholders with Internet
access. Go to www. kemper.com to get up-to-date information, review balances or
even place orders for exchanges.

                      77 - Policies You Should Know About

<PAGE>


When you want to sell more than $50,000 worth of shares, you'll usually need to
place your order in writing and include a signature guarantee. The only
exception is if you want money wired to a bank account that is already on file
with us; in that case, you don't need a signature guarantee. Also, you don't
need a signature guarantee for an exchange, although we may require one in
certain other circumstances.

A signature guarantee is simply a certification of your signature -- a valuable
safeguard against fraud. You can get a signature guarantee from most brokers,
banks, savings institutions and credit unions. Note that you can't get a
signature guarantee from a notary public.

When you sell shares that have a contingent deferred sales charge (CDSC), we
calculate the CDSC as a percentage of what you paid for the shares or what you
are selling them for -- whichever results in the lowest charge to you. In
processing orders to sell shares, we turn to the shares with the lowest CDSC
first. Exchanges from one Kemper fund into another don't affect CDSCs: for each
investment you make, the date you first bought Kemper shares is the date we use
to calculate a CDSC on that particular investment.

There are certain cases in which you may be exempt from a CDSC. These include:

o    the death or disability of an account owner (including a joint owner)

o    withdrawals made through a systematic withdrawal plan

o    withdrawals related to certain retirement or benefit plans

o    redemptions for certain loan advances, hardship provisions or returns of
     excess contributions from retirement plans

o    for Class A shares purchased through the Large Order NAV Purchase
     Privilege, redemption of shares whose dealer of record at the time of the
     investment notifies Kemper Distributors that the dealer waives the
     applicable commission

If you ever have difficulty placing an order by phone or fax, you can always
send us your order in writing.

                      78 - Policies You Should Know About


<PAGE>

In each of these cases, there are a number of additional provisions that apply
in order to be eligible for a CDSC waiver. Your financial representative or
Kemper can answer your questions and help you determine if you are eligible.

If you sell shares in a Kemper fund and then decide to invest with Kemper again
within six months, you can take advantage of the "reinstatement feature." With
this feature, you can put your money back into the same class of a Kemper fund
at its current NAV and for purposes of sales charges it will be treated as if it
had never left Kemper. You'll be reimbursed (in the form of fund shares) for any
CDSC you paid when you sold. Future CDSC calculations will be based on your
original investment date, rather than your reinstatement date. There is also an
option that lets investors who sold Class B shares buy Class A shares with no
sales charge, although they won't be reimbursed for any CDSC they paid. You can
only use the reinstatement feature once for any given group of shares. To take
advantage of this feature, contact Kemper or your financial representative.

Money from shares you sell is normally sent out within one business day of when
your order is processed (not when it is received), although it could be delayed
for up to seven days. There are also two circumstances when it could be longer:
when you are selling shares you bought recently by check and that check hasn't
cleared yet (maximum delay: 10 days) or when unusual circumstances prompt the
SEC to allow further delays. Certain expedited redemption processes may also be
delayed when you are selling recently purchased shares.

                      79 - Policies You Should Know About

<PAGE>


How the funds calculate share price

For each fund in this prospectus, the price at which you buy shares is as
follows:

Class A shares -- net asset value per share, or NAV, adjusted to allow for any
applicable sales charges (see "Choosing A Share Class")

Class B and Class C shares -- net asset value per share, or NAV

To calculate NAV, each share class of each fund uses the following equation:

 TOTAL ASSETS - TOTAL LIABILITIES
- ---------------------------------        = NAV
TOTAL NUMBER OF SHARES OUTSTANDING


For each fund and share class in this prospectus, the price at which you sell
shares is also the NAV, although for Class B and Class C investors a contingent
deferred sales charge may be taken out of the proceeds (see "Choosing A Share
Class").

We typically use market prices to value securities. However, when a market price
isn't available, or when we have reason to believe it doesn't represent market
realities, we may use fair value methods approved by a fund's Board. In such a
case, the fund's value for a security is likely to be different from quoted
market prices.

                      80 - Policies You Should Know About

<PAGE>


Other rights we reserve

For each fund in this prospectus, you should be aware that we may do any of the
following:

o    withhold 31% of your distributions as federal income tax if we have been
     notified by the IRS that you are subject to backup withholding, or if you
     fail to provide us with a correct taxpayer ID number or certification that
     you are exempt from backup withholding

o    reject a new account application if you don't provide a correct Social
     Security or other tax ID number; if the account has already been opened, we
     may give you 30 days' notice to provide the correct number

o    charge you $9 each calendar quarter if your account balance is below $1,000
     for the entire quarter; this policy doesn't apply to most retirement
     accounts or if you have an automatic investment plan

o    pay you for shares you sell by "redeeming in kind," that is, by giving you
     marketable securities (which typically will involve brokerage costs for you
     to liquidate) rather than cash

o    change, add or withdraw various services, fees and account policies (for
     example, we may change or terminate the exchange privilege at any time)

                      81 - Policies You Should Know About

<PAGE>


Understanding Distributions And Taxes

By law, a mutual fund is required to pass through to its shareholders virtually
all of its net earnings. A fund can earn money in two ways: by receiving
interest, dividends or other income from securities it holds, and by selling
securities for more than it paid for them. (A fund's earnings are separate from
any gains or losses stemming from your own purchase of shares.) A fund may not
always pay a distribution for a given period.

The funds have regular schedules for paying out any earnings to shareholders:

o    Income: declared and paid monthly

o    Long-term capital gains: December, or otherwise as needed

The funds may make additional distributions for tax purposes if necessary.

You can choose how to receive your dividends and distributions. You can have
them all automatically reinvested in fund shares (at NAV), all sent to you by
check, have one type reinvested and the other sent to you by check or have them
invested in a different fund. Tell us your preference on your application. If
you don't indicate a preference, your dividends and distributions will all be
reinvested without sales charges. For retirement plans, reinvestment is the only
option.

Buying and selling fund shares will usually have tax consequences for you
(except in an IRA or other tax-advantaged account). Your sales of shares may
result in a capital gain or loss for you; whether long-term or short-term
depends on how long you owned the shares. For tax purposes, an exchange is the
same as a sale.


THE FOLLOWING SIDEBAR TEXT APPEARS NEXT TO THE PRECEDING PARAGRAPHS.

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

Because each shareholder's tax situation is unique, it's always a good idea to
ask your tax professional about the tax consequences of your investments,
including any state and local tax consequences.

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

                   82 - Understanding Distributions and Taxes

<PAGE>


The tax status of the fund earnings you receive, and your own fund transactions,
generally depends on their type:

Generally taxed at ordinary income rates
- -------------------------------------------------------
o short-term capital gains from selling fund shares
- -------------------------------------------------------
o income dividends you receive from a fund
- -------------------------------------------------------
o short-term capital gains distributions received from a
  fund

Generally taxed at capital gains rates
- -------------------------------------------------------
o long-term capital gains from selling fund shares
- -------------------------------------------------------
o long-term capital gains distributions received from a
  fund
- -------------------------------------------------------

You may be able to claim a tax credit or deduction for your share of any foreign
taxes your fund pays.

Your fund will send you detailed tax information every January. These statements
tell you the amount and the tax category of any dividends or distributions you
received. They also have certain details on your purchases and sales of shares.
The tax status of dividends and distributions is the same whether you reinvest
them or not. Dividends or distributions declared in the last quarter of a given
year are taxed in that year, even though you may not receive the money until the
following January.

If you invest right before the fund pays a dividend, you'll be getting some of
your investment back as a taxable dividend. You can avoid this, if you want, by
investing after the fund declares a dividend. In tax-advantaged retirement
accounts you don't need to worry about this.

Corporations may be able to take a dividends- received deduction for a portion
of income dividends they receive.
