DEAR KEMPER FUNDS SHAREHOLDER,

As we enter summer, there isn't much to complain about. For all the yammering
about the "new" economy, the old economy is doing pretty well. Consumers may
hanker for a new GPS handset or a Palm Pilot, but they lust after a suburban
mansion with a garage big enough to hold their luxury car and SUV -- and state
and local governments are laying old-fashioned asphalt almost as fast as
businesses are building the information superhighway. Satisfying both old and
new desires got the economy off to a fast start in the new century -- GDP growth
rose at an annual rate of more than 5 percent in the first quarter. Even with a
modest slowdown possible in the second half, growth for the year 2000 is likely
to be close to 5 percent.
  So everyone is happy, right? Well, almost everyone. Consumers seldom have felt
so confident; businesspeople seldom have behaved so expansively. But there's
still one grump: Federal Reserve Board Chairman Alan Greenspan, who's become
increasingly worried that rapid growth will bring on inflation, and raised
interest rates by half a percentage point (0.50%) accordingly on May 16. The
Fed's move puts the benchmark federal funds rate at 6.5 percent, its highest
level since February 1991, and the more symbolic discount rate at 6.0 percent.
  Despite Greenspan's attempt to slow spending by raising interest rates,
consumers are still splurging, and they show few signs of stopping. We know this
because shoppers are buying the big-ticket items they usually purchase early in
a cycle -- items such as personal computers, mobile phones, jewelry, fancy
kitchen appliances, exercise equipment and big boats. Why are consumers still
buying despite Greenspan's attempts to slow their splurging? There are three
answers: deflation, wealth and easy credit.
  Falling prices have made big-ticket items almost irresistible. Since 1997,
prices of kitchen appliances have fallen 4.5 percent, TVs and VCRs 16 percent
and sporting equipment 6.5 percent. Even auto showrooms no longer produce
sticker shock, and drivers have responded with gusto, buying a record 16.9
million cars and light trucks in 1999. 2000 is likely to be the first year in
which automotive sales top 17 million.
  Some of that spending has been made possible by stock market gains: Wall
Street has handed out windfalls to almost anyone holding equities in the past
few years. But consumers who don't own stocks are also spending, thanks to a
decade of debt. Young, poor or new to America? In the 1990s, it didn't matter;
lenders still loved you. While high-income families have been borrowing less,
those lower on the income scale have been borrowing more.
  But it's not just consumers that Greenspan is concerned about; businesses are
splurging as well. During 1999, businesses increased spending on computers and
peripherals by 35 percent and spending on communications equipment by 25 percent
(both after adjusting for price declines). Far from slowing down this year, we
expect investment in these two categories to accelerate -- to 40 percent growth
for computers and 30 percent growth for communications equipment.
  And just like consumers, businesses are borrowing to buy. You may think that
with booming sales, entrepreneurs are cash-rich and can afford it. But while
1999 saw economy-wide earnings jump 10 percent and profits of Standard and
Poor's (S&P) 500 companies leap nearly 14 percent, internal cash covered less
than 84 percent of capital spending. With the exception of 1998, that's the
lowest on record. Last year alone, corporate debt shot up by more than 11
percent to $560 billion. And new economy companies are no exception; they have
more debt than most people realize, issuing more than half of all convertible
bonds.
  All this debt could cause problems. Although we've increased our 2001
inflation outlook to nearly 3 percent -- an entire percentage point higher than
our prediction three months ago -- we're not particularly worried about
inflation. It's the heavy borrowing we're concerned about. Debt continues to
exceed income growth, and when Greenspan succeeds in slowing the economy with
higher interest rates (which he will succeed in doing), all of the debt American
consumers and businesses are taking on could be tricky to handle. Private
financial obligations must be paid with personal income and corporate profits.
When the economy slows, personal income stagnates and corporate profits often
fall -- which makes it harder to pay off those debts. Consumers and businesses
may have to sell their assets to pay off the debt, and they may risk going into
default.
  That being the case, a gradual economic slowdown may be in everyone's best
interest. But "gradual" is the key. Both the old and new economy have a lot
riding on the Fed's ability to rein in growth softly and smoothly, because
abrupt slowdowns encourage consumers and businesses to sell assets -- and
perhaps risk bankruptcy -- to pay off debt, as described above.
  A gradual slowdown seems to be what the Fed is seeking, but for all of
Greenspan's semi-tough talk, some indicators suggest that monetary policy has
actually been lax. Broad money and credit creation have vastly exceeded
economic activity since 1995, and no central bank can allow that to continue
indefinitely without creating

inflation. If we begin to see higher core inflation, the Fed will have to deal
with all that money it's created in a less gradualist manner -- and that could
get tricky. Financial turmoil accompanied each of the Fed's last two efforts to
slow the economy down. In 1994, there was a bond market meltdown that resulted
in a Mexican debt crisis. After a more timid Fed tightening in 1997, crises in
Asia were followed by problems with Russian debt, Brazilian debt and a large
American hedge fund. We don't think this is a coincidence: The global debt
market is so vast and interconnected that it's highly vulnerable to a rise in
the cost of its basic raw material -- short-term funds.
  Let's hope, then, that the Fed can slow the economy without upsetting the
financial applecart, because that could affect everyone. After all, the old
economy and the new economy are wedded in many ways. Much of the money that
flows to IPOs is available because mature industries have borrowed to carry out
mergers and share buybacks. Old economy companies are the biggest customers of
new economy products. And e-commerce sites are all about moving traditional
goods over old-fashioned highways. Despite a lot of talk about old and new,
we're all in this economy together.
  Happily, financial markets got some better news along that front in late May
and early June. A range of economic data, from retail sales to mortgage
applications to the all-important employment report, began to point to somewhat
softer economic growth. If the Fed believes that the economy is finally slowing
in response to its tightening, the end of the rate hikes could be in sight.
Markets certainly were willing to believe, and they staged a strong relief rally
in late May and early June. While we don't expect a quick end to market
volatility, a slowdown in growth would be most welcome, and would make the
outlook for both stocks and bonds better for the remainder of the year.

                             POTENTIAL GREW AS THE FEDERAL RESERVE RAISED
                             INTEREST RATES. MORTGAGES GENERALLY UNDERPERFORMED
                             COMPARABLE-MATURITY TREASURY NOTES AND BONDS DURING
                             THE FIRST HALF OF FISCAL YEAR 2000.

Q     HOW DID THE U.S. BOND MARKET PERFORM DURING THE FIRST SIX MONTHS OF FISCAL
YEAR 2000?

A     Preserving capital was challenging as the Treasury yield curve inverted
and the difference in yield spread between Treasuries and mortgage debt widened.
Strong economic growth prompted the Federal Reserve to raise its short-term
interest-rate target three times by a total of 75 basis points (0.75 percent) to
6.0 percent. Between October 31, 1999, and April 30, 2000, yields for five-year
Treasuries increased 60 basis points (0.60 percent) while yields for long-term
bonds fell 20 basis points (0.20 percent). By April 30, 2000, five-year Treasury
notes yielded 6.54 percent, 58 basis points more than 30-year Treasury bonds.

  Mortgage interest rates for consumers reached their highest level in three
years. Still, housing and related consumer spending remained brisk as many
consumers turned to adjustable-rate mortgages (ARMs). Consumer credit rose at an
11.2 percent rate in the first quarter of 2000, the fastest pace since 1995.
Many bond market professionals anticipate that to prevent the economy from
overheating, the Fed will raise its interest-rate target beyond 6.50 percent
before the November 2000 national elections.

Q     HOW DID KEMPER U.S. GOVERNMENT SECURITIES FUND DO IN THIS ENVIRONMENT?

A     With dividends reinvested, the fund provided a modest 1.09 percent total
return (Class A shares, unadjusted for sales charge) for the six months ended
April 30, 2000. The fund's return was less than the 1.70 percent return of the
unmanaged Salomon Smith Barney 30-Year GNMA index and slightly less than the
average fund in the Lipper GNMA Funds category (which rose 1.15 percent). The
fund's duration (see Terms to Know on page 7) was longer than its benchmark at
the start of calendar year 2000, and this hurt our relative performance. We
gradually reduced duration by about half a year so that by April 30, the fund's
duration of 4.4 years nearly matched the index.

U.S. TREASURY YIELDS

Yields on intermediate Treasuries increased substantially between October 31,
1999, and April 30, 2000.

PERFORMANCE UPDATE

Q     WHY DID SHORT-TERM BOND YIELDS RISE WHILE LONG-TERM YIELDS FELL?

A     Since January, normal relationships between bonds of different maturities
have been obscured. Usually, 30-year bonds provide more income potential than
securities maturing in 10 years or less, since they involve more interest-rate
risk. However, this past winter 30-year bonds rallied after the Treasury
announced plans to buy back some long-term bonds from investors. Prior to the
announcement, some institutional investors made large investments based on the
belief that long-term Treasury prices would fall sharply this year. When these
investors realized that the government's action would reduce the supply of
30-year bonds, these securities suddenly became a much more prized commodity.

Q     DID MORTGAGES RALLY, TOO?

A     Not much. High-quality mortgage bond prices did not rise to the same
degree as long-term Treasuries after the Treasury's announcement. In fact, as
the Fed raised short-term interest rates, the income potential of mortgage
securities rose to its highest level in more than three years.

  Also, this past winter, the mortgage market was negatively affected by
comments from the Treasury about the implicit government guarantees associated
with Fannie Mae (FNMA) and Freddie Mac (FHLMC) securities. Some bond investors
also grew concerned about the regulatory environment for Fannie Mae and Freddie
Mac, two of the largest private mortgage market participants. In general,
mortgages backed by the Government National Mortgage Association (GNMA, or
Ginnie Maes) outperformed FNMA securities and other forms of mortgage debt
between October and April. The fund's positioning of a majority of its portfolio
in GNMA securities (see Portfolio Composition) helped its performance during the
first half of fiscal year 2000.

Q     IS THERE ANY WAY TO ESTIMATE HOW MUCH A GIVEN CHANGE IN INTEREST RATES CAN
AFFECT THE RETURN FROM INVESTMENT-GRADE BONDS?

A     Generally, a 100-basis-point increase in interest rates translates into a
price decline of slightly more than one percent for a bond or fixed-income
mutual fund that has an average maturity of one year. Bond prices and
fixed-income mutual fund net asset values are also affected by market factors
such as credit risk with corporate bonds and extension risk with mortgages. The
fund's results were fully in line with market conditions.

Q     WHAT'S YOUR OUTLOOK FOR KEMPER U.S. GOVERNMENT SECURITIES FUND FOR THE
MONTHS AHEAD?

A     A dual dynamic of the Fed's attempt to keep inflation in check and an
overall reduction in bond supply may dictate what happens this year. We could
easily see more rate hikes from the Fed, especially given that the government's
March consumer price data showed that inflation was running at its worst pace in
five years.

  Over the past several years, even small whiffs of inflation from one or two
government statistics that deviate from analysts' expectations have caused
equity and bond prices to rise or fall substantially in a single day. We believe
these overreactions should eventually subside. For that to happen, however, we
believe that U.S. economic growth will have to slow from its current rapid pace
(7.3 percent as measured by Gross Domestic Product).

  Given the current environment, we intend to remain somewhat defensive. We are
comfortable that this positioning can allow us to take advantage of increases in
income potential consistent with our efforts to preserve principal. For
investors seeking to reduce the volatility of an equity portfolio, we think the
fund could be an attractive alternative.

TERMS TO KNOW

ADJUSTABLE-RATE MORTGAGE (ARM) A mortgage whose interest rate adjusts
periodically based on changes to a corresponding index rate. To help protect the
borrower against dramatic rate increases in a short period of time, ARMs are
often originated with interest-rate caps. An interest-rate cap assures the
borrower that the rate will not adjust beyond a certain point within a specific
period.

BASIS POINT The movement of interest rates or yields expressed in hundredths of
a percent. For example, an increase in yield from 5 percent to 5.50 percent is
50 basis points.

DURATION The interest-rate sensitivity of a fixed-income investment or
portfolio, measured in years. The longer the duration, the greater the
portfolio's sensitivity to interest-rate fluctuations.

FEDERAL FUNDS RATE The interest rate that banks charge each other on overnight
loans. The Federal Reserve Board's Open Market Committee sets a target rate to
either make credit more easily available or tighten monetary policy in an
attempt to avoid economic imbalances such as high inflation.

GROSS DOMESTIC PRODUCT (GDP) The market value of goods and services produced by
a country during a specified period. It acts as a useful gauge when measuring
the strength of an economy, especially when comparing different time periods.

INVERTED YIELD CURVE A market phenomenon in which intermediate-term bonds
(securities with one- to 10-year maturities) have higher income potential and
current yields than long-term bonds (securities with 10- to 30-year maturities).
Historically it has occurred during a period of rising short-term interest rates
and been viewed as an indicator of a future economic slowdown.

 NOTES TO PORTFOLIO OF INVESTMENTS

  * Repurchase agreements are fully collateralized by U.S. Treasury or
    Government agency securities.

 ** At April 30, 2000, these securities, in part or in whole, have been
    segregated to cover initial margin requirements for open futures contracts.

*** The investments in mortgage-backed securities of the Government National
    Mortgage Association are interests in separate pools of mortgages. All
    separate investments in each of these issues which have similar coupon rates
    have been aggregated for presentation purposes in the Portfolio of
    Investments. Effective maturities of these investments will be shorter than
    stated maturities due to prepayments.

(a)  The cost for federal income tax purposes was $2,957,824,918. At April 30,
     2000, the net unrealized depreciation for all securities based on tax cost
     was $55,260,104. This consisted of aggregate gross unrealized appreciation
     for all securities in which there was an excess of market value over tax
     cost of $16,631,255 and aggregate gross unrealized depreciation for all
     securities in which there was an excess of tax cost over market value of

                             initial sales charge. Class B shares are offered
                             without an initial sales charge but are subject to
                             higher ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions. Class B shares automatically
                             convert to Class A shares six years after issuance.
                             Class C shares are offered without an initial sales
                             charge but are subject to higher ongoing expenses
                             than Class A shares and a contingent deferred sales
                             charge payable upon certain redemptions within one
                             year of purchase. Class C shares do not convert
                             into another class. Class I shares are offered to a
                             limited group of investors, are not subject to
                             initial or contingent deferred sales charges and
                             have lower ongoing expenses than other classes.

                             Investment income, realized and unrealized gains
                             and losses, and certain fund-level expenses and
                             expense reductions, if any, are borne pro rata on
                             the basis of relative net assets by the holders of
                             all classes of shares except that each class bears
                             certain expenses unique to that class such as
                             distribution services, shareholder services,
                             administrative services and certain other class
                             specific expenses. Differences in class expenses
                             may result in payment of different per share
                             dividends by class. All shares of the Fund have
                             equal rights with respect to voting subject to
                             class specific arrangements.

                             The Fund's financial statements are prepared in
                             accordance with generally accepted accounting
                             principles which require the use of management
                             estimates. The policies described below are
                             followed consistently by the Fund in the
                             preparation of its financial statements.

                             SECURITY VALUATION. Portfolio debt securities
                             purchased with an original maturity greater than
                             sixty days are valued by pricing agents approved by
                             the officers of the Fund, whose quotations reflect
                             broker/dealer-supplied valuations and electronic
                             data processing techniques. If the pricing agents
                             are unable to provide such quotations, the most
                             recent bid quotation supplied by a bona fide market
                             maker shall be used. Money market instruments
                             purchased with an original maturity of sixty days
                             or less are valued at amortized cost.

                             All other securities are valued at their fair value
                             as determined in good faith by the Valuation
                             Committee of the Board of Trustees.

                             REPURCHASE AGREEMENTS. The Fund may enter into
                             repurchase agreements with certain banks and
                             broker/dealers whereby the Fund, through its
                             custodian or sub-custodian bank, receives delivery
                             of the underlying securities, the amount of which
                             at the time of purchase and each subsequent
                             business day is required to be maintained at such a
                             level that the market value is equal to at least
                             the principal amount of the repurchase price plus
                             accrued interest.

                             OPTIONS. An option contract is a contract in which
                             the writer of the option grants the buyer of the
                             option the right to purchase from (call option), or
                             sell to (put option), the writer a designated
                             instrument at a specified price within a specified
                             period of time. Certain options, including options
                             on indices, will require cash settlement by the
                             Fund if the option is exercised. During the period,

                                                                              17

NOTES TO FINANCIAL STATEMENTS

                             the Fund purchased put options on securities as a
                             hedge against potential adverse price movements in
                             the value of portfolio assets.

                             The liability representing the Fund's obligation
                             under an exchange traded written option or
                             investment in a purchased option is valued at the
                             last sale price or, in the absence of a sale, the
                             mean between the closing bid and asked prices or at
                             the most recent asked price (bid for purchased
                             options) if no bid and asked price are available.
                             Over-the-counter written or purchased options are
                             valued using dealer supplied quotations. Gain or
                             loss is recognized when the option contract expires
                             or is closed.

                             If the Fund writes a covered call option, the Fund
                             foregoes, in exchange for the premium, the
                             opportunity to profit during the option period from
                             an increase in the market value of the underlying
                             security above the exercise price. If the Fund
                             writes a put option it accepts the risk of a
                             decline in the market value of the underlying
                             security below the exercise price. Over-the-counter
                             options have the risk of the potential inability of
                             counterparties to meet the terms of their
                             contracts. The Fund's maximum exposure to purchased
                             options is limited to the premium initially paid.
                             In addition, certain risks may arise upon entering
                             into option contracts including the risk that an
                             illiquid secondary market will limit the Fund's
                             ability to close out an option contract prior to
                             the expiration date and that a change in the value
                             of the option contract may not correlate exactly
                             with changes in the value of the securities or
                             currencies hedged.

                             FUTURES CONTRACTS. A futures contract is an
                             agreement between a buyer or seller and an
                             established futures exchange or its clearinghouse
                             in which the buyer or seller agrees to take or make
                             a delivery of a specific amount of a financial
                             instrument at a specified price on a specific date
                             (settlement date). During the period, the Fund
                             purchased interest rate futures to manage the
                             duration of the portfolio. In addition, the Fund
                             also sold interest rate futures to hedge against
                             declines in the value of portfolio securities.

                             Upon entering into a futures contract, the Fund is
                             required to deposit with a financial intermediary
                             an amount ("initial margin") equal to a certain
                             percentage of the face value indicated in the
                             futures contract. Subsequent payments ("variation
                             margin") are made or received by the Fund dependent
                             upon the daily fluctuations in the value of the
                             underlying security and are recorded for financial
                             reporting purposes as unrealized gains or losses by
                             the Fund. When entering into a closing transaction,
                             the Fund will realize a gain or loss equal to the
                             difference between the value of the futures
                             contract to sell and the futures contract to buy.
                             Futures contracts are valued at the most recent
                             settlement price.

                             Certain risks may arise upon entering into futures
                             contracts, including the risk that an illiquid
                             secondary market will limit the Fund's ability to
                             close out a futures contract prior to the
                             settlement date and that a change in the value of a
                             futures contract may not correlate exactly with the
                             changes in the value of the securities or
                             currencies hedged. When utilizing futures contracts
                             to hedge, the Fund gives up the opportunity to
                             profit from favorable price movements in the hedged
                             positions during the term of the contract.

                             MORTGAGE DOLLAR ROLLS. The Fund may enter into
                             mortgage dollar rolls in which the Fund sells
                             mortgage-backed securities for delivery in the
                             current month and simultaneously contracts to
                             repurchase similar, but not identical, securities
                             on a fixed date. The Fund receives compensation as
                             consideration for entering into

NOTES TO FINANCIAL STATEMENTS

                             the commitment to repurchase. The compensation is
                             paid in the form of a fee which is recorded as
                             deferred income and amortized to income over the
                             roll period, or alternatively, a lower price for
                             the security upon its repurchase. Mortgage dollar
                             rolls may be renewed with a new sale and repurchase
                             price and a cash settlement made at each renewal
                             without physical delivery of the securities subject
                             to the contract.

                             WHEN ISSUED/DELAYED DELIVERY SECURITIES. The Fund
                             may purchase securities with delivery or payment to
                             occur at a later date beyond the normal settlement
                             period. At the time the Fund enters into a
                             commitment to purchase a security, the transaction
                             is recorded and the value of the security is
                             reflected in the net asset value. The value of the
                             security may vary with market fluctuations. No
                             interest accrues to the Fund until payment takes
                             place. At the time the Fund enters into this type
                             of transaction it is required to segregate cash or
                             other liquid assets at least equal to the amount of
                             the commitment.

                             FEDERAL INCOME TAXES. The Fund's policy is to
                             comply with the requirements of the Internal
                             Revenue Code, as amended, which are applicable to
                             regulated investment companies and to distribute
                             all of its taxable income to its shareholders.
                             Accordingly, the Fund paid no federal income taxes
                             and no federal income tax provision was required.

                             At October 31, 1999, the Fund had a net tax basis
                             capital loss carryforward of approximately
                             $632,822,000 which may be applied against any
                             realized net taxable capital gains of each
                             succeeding year until fully utilized or until
                             October 31, 2002 (485,042,000) or October 31, 2003
                             ($69,777,000) or October 31, 2004 (51,945,000) or
                             October 31, 2007 (26,058,000), the respective
                             expiration dates, whichever occurs first.

                             DISTRIBUTION OF INCOME AND GAINS. Distributions of
                             net investment income, if any, are made monthly.
                             Net realized gains from investment transactions, in
                             excess of available capital loss carryforwards,
                             would be taxable to the Fund if not distributed,
                             and, therefore, will be distributed to shareholders
                             at least annually.

                             The timing and characterization of certain income
                             and capital gains distributions are determined
                             annually in accordance with federal tax regulations
                             which may differ from generally accepted accounting
                             principles. As a result, net investment income
                             (loss) and net realized gain (loss) on investment
                             transactions for a reporting period may differ
                             significantly from distributions during such
                             period. Accordingly, the Fund may periodically make
                             reclassifications among certain of its capital
                             accounts without impacting the net asset value of
                             the Fund.

                             INVESTMENT TRANSACTIONS AND INVESTMENT
                             INCOME. Investment transactions are accounted for
