DEAR SHAREHOLDER,
 
The agreement between the White House and Republican leaders in Congress to
balance the federal budget has effectively ended the market correction that
began in the first quarter. Such sudden progress on balancing the budget, an
initiative that the bond market was anticipating resolution on more than one
year ago, is positive news.

     The next several weeks will find Congress and the Clinton administration
negotiating toward a final agreement. Unlike previous failed proposals that
sought to balance the budget principally by increasing income taxes, the current
plan -- which starts from the base of a relatively small deficit -- proposes to
slow the growth of federal spending. As such, its prospects are promising.

     Natural skeptics are waiting to see specific legislation to see if the
agreement has teeth. While we are optimistic, we need to temper our enthusiasm.
Much of the good news associated with a balanced budget was quickly discounted
in the higher prices in the stock and bond markets.

     Of particular interest to equity investors is the agreement to reduce the
maximum tax rate on capital gains. Although details of the reduction are yet to
be known, the prospect of more favorable tax treatment on gains will have the
short-term effect of supporting stocks -- investors can be expected to postpone
selling until they can qualify for the lower tax rate. With equity sales
essentially "frozen" until the effective date is known, the stock market should
have a considerable underpinning. Once an effective date is determined, we would
expect the pent-up selling to occur once that date is reached. However, then we
shall enjoy the long-term positive effect of the lower tax rate on gains.

     Talk of a balanced budget has shifted the spotlight away from the Federal
Reserve Board's upward pressure on interest rates. Nevertheless, we look for the
Fed to raise rates in May. This action may be the last for a while because the
economy seems to be slowing down in the second quarter, after the rapid 5.6
percent growth in the first quarter of the year. An economic slowdown would
reduce the threat of inflation and reduce the need for further rate hikes by the
Fed.

     In fact, a review of the standard measures of the economy shows little to 
be concerned about. As has been the pattern for more than five years, a few 
strong quarters followed by a few weak quarters have produced an overall 2 
percent to 3 percent rate of growth in gross domestic product (GDP). Job 
creation and the unemployment rate are consistent with a moderately expanding 
economy. Corporate profits continue to grow at an expected 4 to 5 percent rate
in 1997. The Consumer Price Index continues to track at a 2.5 percent to 3.0 
percent rate.

     Just as we see a limited downside to today's rising interest rate  
environment, so is there a limited upside in the near future. The effect of
higher rates will have to work itself through the economy. Higher rates have
significant implications for corporate profitability, debt issuance, credit
extension and international trade. Post-correction cash flows into the
financial markets will be a subject of great scrutiny. One of the factors
driving the stock market to its recent all-time high was the unprecedented high
level of investment through mutual funds, 401(k)s and qualified contribution
plans. It is realistic to expect that, on the margin, some of that cash will
find a home in short-term, liquid investments while the stock market sorts
itself out.

     Leadership in the stock market has been quite narrow and concentrated for 
the past six months in large, multinational companies with familiar consumer 
brand names. The recent rally after the announcement of a balanced budget 
agreement suggests that once monetary policy is also more certain, leadership 
may broaden to include small capitalization stocks.

     Higher interest rates are, of course, anathema to the fixed-income market.
However, bond investors in the last few weeks have been cheered by the balanced
budget proposal and by expectations that interest rates would not go much
higher. We expect the bond market to trade in a very narrow range -- with long-
term interest rates no lower than 6.75 percent and no

Economic activity is a key influence on investment performance and shareholder
decision-making.  Periods of recession or boom, inflation or deflation, credit
expansion or credit crunch have a significant impact on mutual fund performance.

     The following are some significant economic guideposts and their
investment rationale that may help your investment decision-making.  The
10-year Treasury rate and the prime rate are prevailing interest rates.  The

higher than 7.25 percent. One positive effect of the stock market correction was
the widening of spreads available on high yield bonds. As a consequence, high
yield bonds today are more reasonably priced.

     A natural response to increased volatility in the U.S. equity market is to
look abroad. In fact, the valuations of many international markets are more
attractive than the U.S. However, the weak German and Japanese economies make it
difficult to identify many exciting near-term opportunities without careful
research.

     Our recommendation to shareholders is to stay the course and to fight the
temptation to try to time when and where you should be invested. Financial
assets react much quicker today to events. Volatility has returned to the market
and with it heightened uncertainty. Now is the time to rely on your financial
representative for the expertise and the long-term investing discipline that he
or she can provide.

     With this commentary as an economic backdrop, we encourage you to read the
following detailed report of your fund, including an interview with your fund's
portfolio management. Thank you for your continued support. We appreciate the
opportunity to serve your investment needs.

Q   KEMPER U.S. MORTGAGE FUND BEGAN ITS FISCAL YEAR AMIDST MODERATE ECONOMIC
GROWTH AND FAIRLY STABLE INTEREST RATES. HOWEVER, THE FEDERAL RESERVE BOARD (THE
FED) INCREASED SHORT-TERM INTEREST RATES BY 0.25 PERCENT IN MARCH. WHAT CAUSED
THE FED TO ACT?
 
                        
A   At the start of the fiscal year in October 1996, the market believed that
economic growth was moderating and inflation was under control. Relatively weak
Gross Domestic Product (GDP) figures were released that supported this
assumption. Uncertainty began to creep into the market in November, however,
with the presidential and congressional elections. Investors feared the
Republican party might lose control of Congress and reduce the likelihood of a
balanced budget agreement in 1997. The markets rallied, however, with news that
Republicans maintained control of Congress. The election outcome, combined with
lower GDP figures, was positive for the bond market. Treasuries rallied and
prices increased while yields fell.

    This bullish environment changed in December and the rally ended abruptly.
Investors became concerned after Federal Reserve Board Chairman Alan Greenspan
implied in passing that financial assets might be overvalued. This shook the
market and caused yields to rise and securities prices to fall. A suggestion of
strong holiday retail sales coupled with higher-than-expected fourth quarter GDP
growth caused further concern near year-end.
 
    After Greenspan's "irrational exuberance" comment, investors remained 
cautious in early 1997 as strong economic reports surfaced. A stronger-than-
expected employment report indicated a rise in average hourly earnings and an 
increase in hours worked. These indicators suggested solid GDP growth, which 
registered higher-than-expected for the fourth quarter. This relatively strong
GDP figure indicated to the market that the Fed would likely raise interest 
rates to slow the economy. In February, Greenspan stated again that financial
assets may be overvalued. Specifically, Greenspan referenced the level of wage
inflation, and suggested that recent productivity advances may not be able to
offset the current level of wage increases. The Federal Reserve Board did move
to increase short-term rates by 0.25 percent in March. This was considered a 
reemptive move aimed at slowing growth in the economy to maintain a low rate 
of inflation. Remember, excessive growth in the economy indicates the potential
for higher inflation. Inflation is negative for bond investors as it erodes the
"real" value of fixed-income investments.

PERFORMANCE UPDATE
 
 
Q   HOW DID YOU PREPARE THE FUND FOR THE POSSIBILITY OF A FED INTEREST RATE
INCREASE?
                        
A   We began preparing for a possible rate hike in January by shortening the
fund's duration to below that of the fund's peer group. Duration is a
measurement of a fund's sensitivity to interest rates--the shorter the duration,
the less sensitive the fund is to interest rate changes. In addition, we sold
Treasury Notes and purchased GNMA Mortgages, which boosted the fund's mortgage
allocation to 98 percent. With a shorter, more defensive duration and a higher
mortgage allocation, the fund's Class A shares were able to outperform its peer
group average as yields rose during the first three months of 1997 (Class A
shares - 0.03% and Lipper -0.19%). The fund's peer group, as categorized by
Lipper Analytical Services, Inc. consists of 58 other funds like Kemper U.S.
Mortgage Fund, which invest primarily in Government National Mortgage
Association (GNMA) securities.
 
Q   WHAT ADJUSTMENTS DID YOU MAKE TO THE PORTFOLIO TO ALTER THE FUND'S
DURATION?
 
A   To alter duration we adjusted the level of mortgages and Treasuries
throughout the period. In anticipation of the rate hike, we reduced our Treasury
holdings in favor of mortgages, which tend to outperform Treasuries in a rising
interest rate environment.
 
Q   LOOKING BACK IS THERE ANYTHING YOU WISH YOU WOULD HAVE DONE DIFFERENTLY
WITH THE FUND DURING THE PERIOD?
                        
A   We maintained a neutral duration for the fund during the first few months
of the period. That means that the portfolio's duration was similar in length to
that of our peers. In addition, we were underweighted in mortgages. In
hindsight, we now see that we could have positioned the fund with an even
shorter duration and a higher mortgage allocation, which would have helped the
fund more as the market fell in December through the remainder of the period.
However, economic data available at that time gave us conflicting signals about
the true strength of the economy. We erred on the side of caution early in the
period but were rewarded later when rates did rise.
 
Q   WHAT IS YOUR OUTLOOK FOR THE ECONOMY AND THE GOVERNMENT MORTGAGE MARKET?
                        
A   We believe that the economy is fairly strong and we expect it to continue
growing at a rate of 3-4 percent unless interest rates rise high enough to bring
GDP growth down to the 2 1/2 percent range. The Fed will likely raise short-term
rates one or two more times--about 0.25 percent with each tightening. This
should slow the rate of economic growth to the Fed's target rate of 2 1/2
percent. The government market should ultimately benefit from slower growth, but
the short term may be somewhat volatile.
 
Q   WHAT WOULD NEED TO HAPPEN TO ALTER YOUR OUTLOOK?
 
A   If the Fed is not successful in slowing the economy to its target range
with the anticipated rate increases, more tightening would be needed. However,
we don't anticipate that happening. We believe that with the Fed's preemptive
move, it will be successful in slowing the economy's growth.

1    DESCRIPTION OF THE
     FUND                    Kemper U.S. Mortgage Fund is a separate series of
                             Kemper Portfolios, an open-end management
                             investment company organized as a business trust
                             under the laws of Massachusetts. The Fund offers
                             four classes of shares. Class A shares are sold to
                             investors subject to an initial sales charge. Class
                             B shares are sold without an initial sales charge
                             but are subject to higher ongoing expenses than
                             Class A shares and a contingent deferred sales
                             charge payable upon certain redemptions. Class B
                             shares automatically convert to Class A shares six
                             years after issuance. Class C shares are sold
                             without an initial sales charge but are subject to
                             higher ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions within one year of purchase.
                             Class C shares do not convert into another class.
                             Class I shares (none sold through March 31, 1997)
                             are offered to a limited group of investors, are
                             not subject to initial or contingent deferred sales
                             charges and have lower ongoing expenses than other
                             classes. Differences in class expenses will result
                             in the payment of different per share income
                             dividends by class. All shares of the Fund have
                             equal rights with respect to voting, dividends and
                             assets, subject to class specific preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Exchange traded financial futures
                             and options are valued at the settlement price
                             established each day by the board of trade or
                             exchange on which they are traded. Over-the-counter
                             traded fixed income options are valued based upon
                             prices provided by market makers. Other securities
                             and assets are valued at fair value as determined
                             in good faith by the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date (date the order to buy or sell is
                             executed). Interest income is recorded on the
                             accrual basis and includes discount amortization on
                             all fixed income securities and premium
                             amortization on mortgage-backed securities.
                             Realized gains and losses from investment
                             transactions are reported on an identified cost
                             basis.
 
                             The Fund may purchase securities with delivery or
                             payment to occur at a later date. 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
                             equal to the value of the securities purchased. At
                             March 31, 1997 the Fund had $500,208,000 in
                             purchase commitments outstanding (19% of net
                             assets), with a corresponding amount of assets
                             segregated.

                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the earlier of 3:00 p.m. Chicago
                             time or the close of the Exchange. The net asset
                             value per share is determined separately for each
                             class by dividing the Fund's net assets
                             attributable to that class by the number of shares
                             of the class outstanding.
 
                             FEDERAL INCOME TAXES. The Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies during the six
                             months ended March 31, 1997. The accumulated net
                             realized loss on sales of investments for federal

                             recorded on the ex-dividend date. Dividends are
                             determined in accordance with income tax principles
                             which may treat certain transactions differently
                             from generally accepted accounting principles.
 
                             EQUALIZATION ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares is
                             credited or charged to undistributed net investment
                             income so that income per share available for
                             distribution is not affected by sales or
                             redemptions of shares.

6    FINANCIAL FUTURES
     CONTRACTS             The Fund has entered into exchange traded financial
                           futures contracts in order to help protect itself
                           from anticipated market conditions and, as such,
                           bears the risk that arises from entering into these
                           contracts.
                           
                           At the time a Fund enters into a futures contract,
                           it is required to make a margin deposit with its
                           custodian. Subsequently, gain or loss is recognized
                           and payments are made on a daily basis between the
                           Fund and its broker as the market value of the
                           futures contract fluctuates. At March 31, 1997, the
                           market value of assets pledged by the Fund to cover
                           margin requirements for open futures positions was
                           $26,914,000. The Fund also had liquid securities in
                           its portfolio in excess of the face amount of the
                           following short futures positions open at March 31,
                           1997:
