This chart shows the 30-day effective yields as of the end of each month for
Money Market Fund Class A, U.S. Government Money Market Fund and Tax-Exempt
Money Market Fund. 30-day effective yield refers to the income generated by the
fund over a 30-day period. This income is annualized and assumed to be
reinvested.

Past performance does not guarantee future results. The return of your
investment will fluctuate. An investment in the fund is neither insured nor
guaranteed by the U.S. government, and there can be no assurance that the fund
will be able to maintain a stable net asset value of $1 per share.

Since the funds' inceptions, the funds' distributor voluntarily waived certain
12b-1 fees. Without waivers, 30-day effective yields for Money Market Fund Class
A, U.S. Government Money Market Fund and Tax-Exempt Money Market Fund would have
been 4.90%, 4.75% and 2.79%, respectively, on September 30, 1997.

As of September 30, 1997, the 30-day effective yield for Money Market Fund
Class B was 4.15%.

SHORT-TERM INTEREST RATES FLUCTUATED DURING THE PERIOD WITH CHANGING
EXPECTATIONS ABOUT ECONOMIC GROWTH. During fourth quarter 1996, slower growth
led the markets to expect the Federal Reserve Board (Fed) to keep the federal
funds rate*** unchanged. But by late February, the economy was perceived to be
picking up steam - and on March 25 the Fed raised the fed funds rate by 0.25%.
The markets turned around again in the second quarter, reflecting decelerating
inflation and signs that the economy was slowing. In the third quarter,
expectations of weaker economic growth, combined with continued good news about
inflation, resulted in lower bond and money market yields.

WE PROVIDED YOU WITH A COMPETITIVE RETURN DURING THE YEAR BY MANAGING THE FUNDS'
AVERAGE WEIGHTED MATURITY*** AND MAKING SOME CHANGES TO THE STRUCTURE OF THE
FUNDS. We lengthened the average weighted maturity of the funds as we moved
closer to year end 1996 to take advantage of the higher rates available then. We
shortened the maturities in the first part of 1997 as rates began to increase,
and then lengthened again by the end of the first quarter in time for the
decline in short-term rates during the second quarter. Throughout the summer, we
continued to position the funds with longer average weighted maturities than
their respective benchmarks,*** which worked well given the decrease in rates

during the period. Late in the second quarter and early in the third, we added
some one-year securities, thereby positioning the funds in more of a barbell
structure.*** A barbell structure clusters maturities at both the short end of
the yield curve*** (one to three months) and at the longer end (10 to 13
months). The structure works well when the difference between yields on short-
and longer-term securities decreases, which is what happened during the third
quarter of this year.

GOING FORWARD, WE BELIEVE THE PATTERN OF STRONG AND WEAK PERIODS OF ECONOMIC
GROWTH, ALTERNATING WITHOUT EXCESSES IN EITHER DIRECTION, WILL CONTINUE. While
economic indicators are sending mixed signals, it appears the economy is fairly
well balanced. Any changes in Fed policy will depend on economic releases in the
coming months. We will continue to monitor those releases carefully and
formulate our strategy accordingly.

OUR PRIMARY CONCERN IN MANAGING BOTH FUNDS IS THE SAFETY OF YOUR PRINCIPAL. We
continue to use a fundamental approach to identify high-quality, liquid money
market securities that provide competitive yields. Our strategy is designed to
add value by actively positioning the portfolios on the yield curve (13 months
or less), investing in high-quality securities and managing the funds' average
weighted maturity based on our interest rate forecast.

Thank you for your investment in Money Market Fund and/or U.S. Government Money
Market Fund. We remain committed to providing investments that help you achieve
your financial goals.

Sincerely,

DEAR SHAREHOLDERS:

TAX-EXEMPT MONEY MARKET FUND'S YIELD INCREASED SINCE WE REPORTED TO YOU SIX
MONTHS AGO. The fund's seven-day current yield rose from 2.63% on March 31,
1997, to 3.01%* on September 30, 1997. That compares to a yield of 2.81% on
September 30, 1996. Yields fluctuated from month to month as a result of
changing expectations of Federal Reserve Board (Fed) activity and seasonal
technical imbalances. We'll discuss these factors - and how they affected the
fund -- below.

SHORT-TERM INTEREST RATES FLUCTUATED DURING THE PERIOD AS EXPECTATIONS FOR
ECONOMIC GROWTH CHANGED. During fourth quarter 1996, slower growth led the
markets to expect that the Fed would not change the federal funds rate.*** But

September 30, 1997.

raised the fed funds rate by 0.25%. The markets turned around again in the
second quarter, reflecting decelerating inflation and signs that the economy was
slowing. In the third quarter, expectations of weaker economic growth, combined
with continued good news about inflation, resulted in reduced bond yields.

THE MUNICIPAL NOTE SUPPLY SEASON BEGAN IN EARLY JUNE AND ENDED IN THE LATTER
PART OF SEPTEMBER. During this supply glut, the average weighted maturity*** of
our benchmark*** rose from 32 days to 51 days, a year-to-date high. Your fund
followed a similar pattern, rising from 40 days to 57 days during the same
period.

WE TOOK ADVANTAGE OF THE SUPPLY OPPORTUNITY AND PURCHASED A SUBSTANTIAL POSITION
IN HIGH-QUALITY NOTES, AS THEIR YIELDS REPRESENTED CONSIDERABLE VALUE. We also
added some new tax-exempt commercial paper to the fund in the second quarter,
since this group of securities was attractively valued. Purchasing these notes
and commercial paper helped us maintain our allocation of fixed-rate securities
at approximately 35%. Meanwhile, yields on daily and weekly tax-exempt variable
rate securities fluctuated dramatically during the past quarter, ranging from
40% to 100% of their taxable counterparts. However, the trend in these ratios
has been downward as tax-exempt money market fund assets (and demand for the
securities) have risen.

WE INTEND TO CONTINUE MANAGING THE FUND WITH 35% TO 45% FIXED RATE SECURITIES
AND 55% TO 65% VARIABLE RATE SECURITIES. Keeping a significant portion of
variable rate securities allows the fund to take advantage of any increase in
short-term interest rates caused by technical imbalances or an increase in
interest rates caused by the Fed.

TAX-EXEMPT MONEY MARKET FUND (CONTINUED)
- --------------------------------------------------------------------------------

THE FUND'S TOTAL ASSETS INCREASED 12% DURING THE PAST YEAR, MOST LIKELY DUE, IN
PART, TO NERVOUSNESS ABOUT STOCK MARKET VOLATILITY AND POSSIBLE INTEREST RATE
MOVES BY THE FED. While the fund's asset level rose during the year, it
fluctuated month to month. Another factor that may have caused asset
fluctuations in the fund, and tax-exempt money market funds in general, was a
proposal to eliminate favorable tax treatment of municipal income allowed to
corporations. While this proposal was not adopted, it may have prompted
corporations to sell their holdings of tax-exempt money market funds.

WE BELIEVE THE FED WILL DECIDE TO KEEP INTEREST RATES UNCHANGED AT ITS NEXT
MEETING IN NOVEMBER. We will remain cautious in managing your fund's average
maturity until we have a clearer picture of how the economy will unfold.

Thank you for investing in Tax-Exempt Money Market Fund. We remain dedicated to
providing management services and investments that help you achieve your
financial goals.

Sincerely,

(1) ORGANIZATION
 ................................
               Piper Funds Inc. (the company) is registered under the Investment
               Company Act of 1940 (as amended) as a single open-end management
               investment company. The company currently has 12 series,
               including Money Market Fund, U.S. Government Money Market Fund
               and Tax-Exempt Money Market Fund (the funds). Each fund is
               classified as a diversified series. The company's articles of
               incorporation permit the board of directors to create additional
               series in the future.
 
               Money Market Fund commenced offering Class B shares on February
               18, 1997. All shares existing prior to that date were classified
               as Class A shares. Key features of each class are:
 
                  CLASS A:
               - Lower distribution fees than Class B
 
                  CLASS B:
               - Subject to a contingent deferred sales charge upon redemption
 
               - Higher distribution fees than Class A
 
               - Automatic conversion to Class A shares at the beginning of the
               sixth calendar year after issuance
 
               - Available for purchase only in exchange for Class B shares of
               another fund managed by the adviser
 
               The classes of shares of Money Market Fund have the same rights
               and are identical in all respects except that each class bears

(2) SUMMARY OF
    SIGNIFICANT
    ACCOUNTING
    POLICIES
 ................................
                  INVESTMENTS IN SECURITIES
               Pursuant to Rule 2a-7 of the Investment Company Act of 1940 (as
               amended), securities are valued on the basis of amortized cost,
               which approximates market value.
 
               Security transactions are accounted for on the date the
               securities are purchased or sold. Interest income, including
               amortization of discount and premium computed on a straight line
               basis, is accrued daily.
 
                  FEDERAL TAXES
               Each fund is treated separately for federal income tax purposes.
               Each fund intends to comply with the requirements of the Internal
               Revenue Code applicable to regulated investment companies and not
               be subject to federal income tax. Therefore, no income tax
               provision is required. The funds also intend to distribute their
               taxable net investment income and realized gains, if any, to
               avoid the payment of any federal excise taxes.

                  DISTRIBUTIONS TO SHAREHOLDERS
               Distributions to shareholders from net investment income for
               Money Market Fund are declared separately for each class daily
               and reinvested in additional shares of the same class monthly.
               Distributions to shareholders from net investment income for U.S.
               Government Money Market Fund and Tax-Exempt Money Market Fund are
               declared daily and reinvested in additional shares of the funds
               monthly.
 
                  REPURCHASE AGREEMENTS
               For repurchase agreements entered into with certain
               broker-dealers, the funds, along with other affiliated registered
               investment companies, may transfer uninvested cash balances into
               an individual, joint or tri-party trading account, the daily
               aggregate of which is invested in repurchase agreements secured
               by U.S. government or agency obligations. Securities pledged as
               collateral for all individual and joint repurchase agreements are
               held by the funds' custodian bank until maturity of the
               repurchase agreement. Securities pledged as collateral for all
               tri-party repurchase agreements are held by a third-party
               custodian until maturity of the repurchase agreement. Provisions
               for all agreements ensure that the daily market value of the
               collateral is in excess of the repurchase amount, including
               accrued interest, to protect the funds in the event of a default.
 
                  ALLOCATION OF INCOME, EXPENSES AND GAINS(LOSSES)
               Income, expenses (other than class-specific expenses) and
               realized and unrealized gains and losses for Money Market Fund
               are allocated daily to each class of shares based upon the
               relative proportion of net assets represented by such class.
               Class-specific expenses, which include distribution and service
               fees, are charged directly to such class.
 
                  USE OF ESTIMATES
               The preparation of financial statements in conformity with
               generally accepted accounting principles requires management to

Independent Auditors' Report
- --------------------------------------------------------------------------------
 
THE BOARD OF DIRECTORS AND SHAREHOLDERS
PIPER FUNDS INC.:
 
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of Money Market Fund, U.S.
Government Money Market Fund and Tax-Exempt Money Market Fund (funds within
Piper Funds Inc.) as of September 30, 1997, and the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period ended September 30, 1997, and the
financial highlights for each of the years in the five-year period ended
September 30, 1997. These financial statements and the financial highlights are
the responsibility of the funds' management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased but not received, we request confirmations
from brokers and, where replies are not received, we carry out other appropriate
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and the financial highlights referred
to above present fairly, in all material respects, the financial position of
Money Market Fund, U.S. Government Money Market Fund and Tax-Exempt Money Market
Fund at September 30, 1997, and the results of their operations, the changes in
their net assets and the financial highlights for the periods stated in the
paragraph above, in conformity with generally accepted accounting principles.

GLOSSARY OF TERMS ***
- --------------------------------------------------------------------------------

AVERAGE WEIGHTED MATURITY
The average maturity is the mean of the maturity dates of a group of securities.
The term is used to describe the average time before the securities in a fund
mature. Average weighted maturity takes into account the size of each holding
represented.

BARBELL STRUCTURE
A barbell investment structure emphasizes securities with long- and short-term
maturities and de-emphasizes securities with intermediate-range maturities. This
enables a manager to take advantage of the high yields associated with long-term
maturities, while still providing liquidity with short-term maturities.

BENCHMARK: MONEY MARKET FUND
IBC's MONEY FUND REPORT AVERAGES-TM- -- First Tier, as reported by IBC's
MONEY FUND REPORT-TM-, which is an average of money market funds investing
exclusively in first tier securities (securities in the highest rating category
for short-term debt obligations).

BENCHMARK: U.S. GOVERNMENT MONEY MARKET FUND
IBC's MONEY FUND REPORT AVERAGES-TM- -- U.S. Government & Agencies, as reported
by IBC's MONEY FUND REPORT-TM-, which is an average of money market funds
investing in U.S. Treasury securities and government agency obligations.

BENCHMARK: TAX-EXEMPT MONEY MARKET FUND
IBC's MONEY FUND REPORT AVERAGES-TM- -- All Tax-Free, as reported by IBC's MONEY
FUND REPORT-TM-, which is an average of tax-free money funds that are tax-free
at the federal level for the majority of investors.

FEDERAL FUNDS RATE
The federal funds rate is the interest rate charged by banks with excess
reserves at a Federal Reserve district bank to banks needing overnight loans to
meet reserve requirements. Although the Federal Reserve Board sets the target
federal funds rate, the actual federal funds rate is set daily by the market.
Since the rate is determined by market forces, unlike the prime rate and the
discount rate, which are periodically changed by banks and by the Federal
Reserve Board, respectively, it is the most sensitive indicator of the direction
of interest rates.

YIELD CURVE
A graph that shows the relationship between the interest rates paid on bonds and
their maturities, ranging from the shortest maturities to the longest available
(assuming the bonds are all of the same quality). The resulting curve indicates
whether short-term interest rates are higher or lower than long-term rates.
