Dear Shareholders
- --------------------------------------------------------------------------------

Financial markets have not only continued the strength of the past few years,
they've actually accelerated their rate of gain. During just the first quarter
of 1998, for example, the Standard & Poor's 500 Index generated a total return
of 13.94%* -- its third highest quarterly return in the past 10 years. This
compares to its previous quarter return, a much lower 2.87%.* This acceleration
is quite surprising, given the uncertainty of the impact of the Asian crisis on
the U.S. economy and the slowdown in expected corporate profit growth. Inflation
has continued to trend downward, and interest rates declined only slightly
during the period.

As we look to the future, we do anticipate the economy will slow. We believe 
the Asian crisis ultimately will have some negative impact on the U.S. 
economy, be it from lower demand for American goods or increased pricing 
pressures from competing Asian goods. Additionally, the Federal Reserve has 
maintained a relatively high level of short-term interest rates even as 
inflation has continued to decline. The real return of Fed funds at slightly 
over 4% is the highest real return since the 1980s. The term structure of the 
fixed income market continues to be relatively flat, with the difference in 
yields between 30-year Treasury bonds and three-month Treasury bills at 
approximately 0.7%.

Justifying stock market returns like these on the basis of fundamental analysis
continues to be extremely difficult. Price to earnings multiples in the mid-20s
are clearly at the top end of the historical average. Even with the almost
perfect investment environment, further gains do appear limited, particularly
given the slowdown in overall corporate earnings to an anemic yearly rate of
change of less than 3% as of March 31. If the stock market is to continue to
move up, it appears investors must be willing to accept higher valuation
multiples.

HOLDING A LONG-TERM VIEW

This environment has caused us to to keep Piper Funds' investment strategies
neutral to relative market benchmarks. In fixed income markets, we anticipate
only small changes in interest rates for the foreseeable future, which provides
little opportunity for capital appreciation in bond prices. In large stocks, we
continue to seek out companies that we believe are relatively undervalued, given
their future growth prospects, and we continue to seek and focus on small and
mid-sized companies with high growth prospects and solid fundamentals. We
believe this is a time for investors to reaffirm their investment goals and risk
tolerances, and position their portfolios at comfortable levels.

You may be assured that we understand the importance of a long-term investment
horizon. Even in this ever-changing market environment, we stand firm in our
belief that maintaining sound, disciplined investment strategies is essential to
achieving consistent, competitive performance.

GOING FORWARD

On May 1, U.S. Bancorp acquired Piper Jaffray Companies, the parent company of
the funds' investment advisor. As a result of the acquisition, the Piper Funds
board of directors has recommended the reorganization of the funds into the
First American family of funds. This family is managed by First American Asset
Management, -> [LOGO] the asset management division of U.S. Bank National
Association. As shareholders, you have the right to vote on this reorganization
of your funds, and we encourage you to do so. Please read your proxy materials
- -> [GRAPHIC] carefully. If you have any questions, please contact your
investment executive or call Mutual Fund Services at 800 866-7778.

Sincerely,


/s/ Paul A. Dow

EMERGING MARKETS GROWTH FUND

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

May 17, 1998

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

DEAR SHAREHOLDERS:

EMERGING MARKETS GROWTH FUND CLASS A RETURNED -10.85% FOR THE SIX-MONTH PERIOD
ENDED MARCH 31, 1998, WHICH INCLUDES REINVESTED DISTRIBUTIONS BUT NOT THE FUND'S
SALES CHARGE.* This compares to a -12.41% return for the MSCI Emerging Markets
Free Index+ and a -12.86% for the Lipper Emerging Markets Funds Average++ over
the same time period. The economic and currency crisis in Asia that spilled over
to most emerging markets was largely responsible for the fund's investment
results. The fund outperformed its respective benchmark by maintaining an
overweighted*** position in Latin America, which recorded relatively good
investment results over the past six months.

THE ECONOMIC AND CURRENCY CRISIS IN SOUTHEAST ASIA THAT SURFACED LATE LAST YEAR
WAS THE MOST SIGNIFICANT EVENT DURING THE PERIOD. The crisis caused investors to
grow concerned about the prospects for global deflation, sending most Asian
markets into a steep decline. The Asian turmoil also had a negative impact on
established markets, including the United States. When it became apparent that
the problems in southeast Asia would have a significant impact on markets within
the region, we reduced the fund's exposure there, which helped preserve
shareholder capital.

LATIN AMERICAN MARKETS WERE AFFECTED BY THE ASIAN SITUATION BUT FARED MUCH
BETTER THAN THEIR COUNTERPARTS ALONG THE PACIFIC RIM. After the crisis hit,
Latin American markets were relatively quiet,

Performance prior to June 21, 1996, is that of Hercules Latin American Value
Fund, the fund's predecessor. International investing involves risks not
typically associated with U.S. investing, including currency fluctuations,
political instability and different accounting standards. Risks are particularly
significant when investing in emerging markets. See the prospectus for more
complete information regarding risks. During most periods, the fund's advisor
waived or paid certain expenses and/or the fund's distributor voluntarily waived
certain 12b-1 fees. Without waivers, Class A returns would have been lower.

EMERGING MARKETS GROWTH FUND  (continued)

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

as emerging market investors focused their attention on the Pacific Rim in
search of good values following the sharp selloff. Late in the period, however,
generally strong earnings growth, ongoing economic reforms and good performance
on the inflation front helped some Latin American markets recover, most notably
Brazil. Signs that the Brazilian government was taking serious steps to bolster
the country's sagging economy and ongoing privatization helped fuel the rally.
The fund was overweighted in these markets, compared to its benchmark, which
helped its performance.

THE FUND'S EXPOSURE TO EASTERN EUROPE AND AFRICA MANAGED TO SOFTEN THE BLOW  OF
THE ASIAN CRISIS. Poland and Greece were among the better performers,
particularly during the last three months of the period. Poland's advance was
fueled by strong fundamentals, such as a solid economy and improving corporate
earnings. In Greece, investors reacted favorably to the government's decision to
devalue *** the currency relative to a basket of European currencies. Ghana, one
of the world's smallest equity markets, also recorded strong investment results.
Three stocks in this region that registered solid investment results for the
fund were, OTP, one of Hungary's leading banks (3.9% of total assets as of March
31, 1998), Al-Ahran Beverages in Egypt (3.9%) and Goody's, a food company in
Greece (3.3%). Each company benefited from solid earnings growth.

ANOTHER SMALL MARKET THAT CONTRIBUTED FAVORABLY TO THE FUND'S INVESTMENT RESULTS
WAS RUSSIA. Last year, Russia was one of the world's best performing markets. A
favorable, though somewhat uncertain political environment coupled with strong
earnings growth by established corporations that have benefited from the
country's changing economic environment lifted stock prices. One of the fund's
better performing stocks in Russia was Vimpel-Communications (2.9%), a leading
cellular telephone company. As long as President Yeltsin remains in power, we
believe the prospects for Russian equities, on balance, appear favorable.

OUR OUTLOOK FOR THE SOUTHEAST ASIAN MARKETS REMAINS CAUTIOUS. The recent bounce
back in some key markets, such as Malaysia, is a positive sign. However, since
the full impact of Asia's economic problems is still uncertain, further market
volatility is anticipated. Weakness in the Japanese yen, which is a possibility
given the country's fragile economic condition, may also put Asian currencies

under pressure. Since valuations are generally attractive in Asia, we intend to
use any major market downturns to increase selectively our exposure in the
region.

OUR FORECAST FOR LATIN AMERICAN MARKETS IS SOMEWHAT OPTIMISTIC. While any
additional problems in Asia may affect Latin American markets, we do not believe
they will have a long-term impact on the region. Most economies in Latin America
are improving, and corporate earnings growth is much stronger than in Asia. Once
investors get beyond the fear caused by the Asian crisis, we believe Latin
American equities will again be in favor.

Thank you for your investment in Emerging Markets Growth Fund. As always, we
will continue to maintain a well-diversified portfolio to reduce risk and
enhance growth potential in helping you seek your long-term investment goals.

Sincerely,


/s/ Richard Muckart

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1998, PACIFIC-EUROPEAN GROWTH FUND
CLASS A PRODUCED A TOTAL RETURN OF 4.51%, WITH ALL DISTRIBUTIONS REINVESTED, BUT
NOT INCLUDING THE FUND'S SALES CHARGE.* Over the same time frame, the MSCI
European, Australian, Far East (EAFE) Index+, the fund's benchmark, ***
returned 5.87% and the Lipper International Funds Average++ returned 5.9%. The
fund's underperformance was largely due to its exposure to Pacific Basin stocks,
which, on balance, registered lower investment results than those recorded by
their European counterparts.

JAPANESE STOCKS DETRACTED FROM THE FUND'S INVESTMENT RESULTS, AS THE COUNTRY'S
WEAK ECONOMY CONTINUED TO IMPACT JAPANESE STOCK VALUES. After struggling through
the last three months of 1997, the Japanese stock market rallied in January on
reports the government was taking serious steps to stimulate the economy.
However, when the government failed to introduce a meaningful economic package,
the market gave back virtually all of those early-year gains in February and
March. Our decision to reduce the fund's weighting in Japan during the January
rally helped enhance the fund's performance.

THE FUND'S OVERWEIGHTED POSITIONS IN THE UNITED KINGDOM, FRANCE AND ITALY
CONTRIBUTED FAVORABLY TO ITS INVESTMENT RESULTS. During the period, all three
markets recorded solid performance. One stock that

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Safety of principal is not guaranteed.
Performance prior to its conversion to an open-end fund on August 31, 1992, is
based on its experience as a closed-end fund. International investing involves
risks not typically associated with U.S. investing, including currency
fluctuations, political instability and different accounting standards. See the
prospectus for more complete information regarding risks. During most periods,
the fund's advisor waived or paid certain expenses and/or the fund's distributor
voluntarily waived certain 12b-1 fees. Without waivers, returns would have been
lower.

All fund and benchmark returns include reinvested distributions.

INTERNATIONAL GROWTH

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

PACIFIC-EUROPEAN GROWTH FUND (continued)

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

contributed favorably to the fund's investment results was Lloyds TSB (1.8% of
total assets as of March 31,1998), a premier main street bank in London with
solid earnings growth. The fund also benefited from its exposure to financial
and consumer stocks in the Netherlands.

SEVERAL ASIAN MARKETS SUFFERED DUE TO THE ECONOMIC AND CURRENCY CRISIS THAT
SWEPT THE REGION BEGINNING LATE OCTOBER. Late in the period, many of the Asian
markets rebounded from the market fallout. However, several markets continued to
struggle, most notably Indonesia. The fund's investments in Hong Kong and
Australia, two markets that outperformed the average performance in the region,
proved to be a positive defensive move in an otherwise difficult environment.

LATIN AMERICA WAS NEGATIVELY IMPACTED BY THE PROBLEMS IN ASIA, BUT MANY MARKETS
REBOUNDED EARLY IN 1998. In this environment, the fund's relatively small
position in Latin America contributed positively to investment results.

LOOKING AHEAD, OUR OUTLOOK FOR JAPANESE STOCKS REMAINS TENUOUS. The 
government does not appear to be ready to introduce a bona fide economic 
stimulus package. Additionally, any deepening of the financial crisis in Asia 
is likely to have an impact on Japan's economy and its financial markets. 
Given this forecast, we intend to maintain our underweighted*** exposure in 
Japan and may continue to use significant upturns in the Japanese market to 
reduce our weighting further.

OUR OUTLOOK FOR CONTINENTAL EUROPE IS FAVORABLE. Generally good economic
conditions, benign inflation and low interest rates should serve as a strong
foundation for higher equity prices on the continent. Additionally, the wave of
restructurings is expected to continue, which should translate to improving
corporate earnings. Finally, the fact that the continent is still on target to
achieve economic union by January 1, 1999, should bode well for European
equities.

INTERNATIONAL GROWTH

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

Pacific-European Growth Fund (continued)

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

WE INTEND TO MAINTAIN A CAUTIOUS INVESTMENT POSTURE IN THE PACIFIC BASIN.
Countries are still struggling to rebound from the severe crisis that gripped
the region late last year. While the Asian financial crisis has not had a
serious impact on key financial markets outside the region in recent months, it
continues to pose a serious threat to the global economy. We intend to maintain
a heavy weighting in countries unlikely to be affected by another major fallout,
most notably Australia. We also believe stock selection will be critically
important in achieving solid returns throughout the Pacific Basin.

Thank you for your investment in Pacific-European Growth Fund. As always we will
continue to focus our efforts on finding high-quality, financially sound
companies with above-average growth prospects in seeking the fund's long-term
investment goal.

Sincerely,

/s/ Richard Muckart

(1) ORGANIZATION
 ................................
                      Piper Global 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 outstanding two series (the funds):
                      Emerging Markets Growth Fund and Pacific-European Growth
                      Fund, which are classified as non-diversified and
                      diversified series, respectively. The company's articles
                      of incorporation permit the board of directors to create
                      additional series in the future.
 
                      The funds commenced offering Class B shares and
                      Pacific-European Growth Fund commenced offering Class Y
                      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:
                      - Subject to a front-end sales charge
 
                      - Lower distribution and service fees than Class B
 
                      CLASS B:
                      - No front-end sales charge
 
                      - Subject to a contingent deferred sales charge upon
                      redemption
 
                      - Higher distribution and service fees than Class A
 
                      - Automatic conversion to Class A shares at the beginning
                      of the sixth calendar year after issuance
 
                      CLASS Y:
                      - Requires a minimum initial investment of $1 million
 
                      - No front-end or contingent deferred sales charges
 
                      - No distribution and service fees
 
                      The classes of shares have the same rights and are
                      identical in all respects except that each class bears
                      different distribution expenses, has exclusive voting
                      rights with respect to matters affecting that class and
                      has different exchange privileges.
 
                      Emerging Markets Growth Fund invests primarily in common
                      stocks of emerging securities markets. Emerging securities
                      markets can be found in regions such as Latin America,
                      Asia, Eastern Europe, the Middle East and Africa.
 
                      Pacific-European Growth Fund invests primarily in the
                      Pacific Basin (for example, Japan, Hong Kong, Malaysia,
                      Singapore or Thailand) and Europe (including Eastern
                      Europe). Pacific-European Growth Fund acquired the net
                      assets of Hercules European Value Fund and Hercules
                      Pacific Basin Value Fund on June 21, 1996, via a tax-free
                      reorganization.

                      INVESTMENTS IN SECURITIES
                      Portfolio securities for which market quotations are
                      readily available are valued at current market value. If
                      market quotations or valuations are not readily available,
                      or if such quotations or valuations are believed to be

                      valued according to procedures adopted by the funds' board
                      of directors in good faith at "fair value", that is, a
                      price that the fund might reasonably expect to receive for
                      the security or other asset upon its current sale.
 
                      Pricing services value domestic and foreign equity
                      securities (and occasionally fixed-income securities)
                      traded on a securities exchange or Nasdaq at the last
                      reported sale price, up to the time of valuation. If there
                      are no reported sales of a security on the valuation date,
                      it is valued at the mean between the published bid and
                      asked prices reported by the exchange or Nasdaq. If there
                      are no sales and no published bid and asked quotations for
                      a security on the valuation date or the security is not
                      traded on an exchange or Nasdaq, the pricing service may
                      obtain market quotations directly from broker-dealers.
 
                      Securities transactions are accounted for on the date
                      securities are purchased or sold. Realized gains and
                      losses are calculated on the identified-cost basis.
                      Dividend income is recognized on the ex-dividend date and
                      interest income, including amortization of bond discount
                      and premium, is recorded on an accrual basis.
 
                      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.
 
                      Net investment income and net realized gains (losses) may
                      differ for financial statement and tax purposes primarily
                      because of the recognition of certain foreign currency
                      gains (losses) as ordinary income (loss) for tax purposes,
                      the "mark-to-market" of certain Passive Foreign Investment
                      Companies (PFICs) for tax purposes, the "mark-to-market"
                      of certain investments for tax purposes, losses deferred
                      due to "wash sale" transactions and the non-deductibility
                      of amortization of organization costs. The character of
                      distributions made during the year from net investment
                      income or net realized gains may differ from its ultimate
                      characterization for federal income tax purposes. In
                      addition, due to the timing of dividend distributions, the
                      fiscal year in which amounts are distributed may differ
                      from the year that the income or realized gains or losses
                      were recorded by the funds.
 
                      DISTRIBUTIONS TO SHAREHOLDERS
                      Distributions to shareholders from net investment income
                      will be declared separately for each class and paid at
                      least annually. Net realized gains distributions, if any,
                      will be made at least annually. Distributions are payable
                      in cash or reinvested in additional shares of the same
                      class.
 
                      ORGANIZATION COSTS
                      Organization costs were incurred in connection with the
                      start up and initial registration of Emerging Markets
                      Growth Fund's predecessor. These costs are amortized over
                      60 months on a straight-line basis. If any or all of the
                      shares representing initial capital of the fund are
                      redeemed by any holder

                      thereof prior to the end of the amortization period, the
                      proceeds will be reduced by the unamortized organization
                      cost balance in the same proportion as the number of
                      shares redeemed bears to the number of initial shares
                      outstanding preceding the redemption.
 
                      FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS
                      Securities and other assets and liabilities denominated in
                      foreign currencies are translated into U.S. dollars at the
                      closing rate of exchange. Foreign currency amounts related
                      to the purchase or sale of securities and income and
                      expenses are translated at the exchange rate on the
                      transaction date. For financial reporting purposes the
                      realized and unrealized gain or loss on investments
                      reflects changes in exchange rates as well as changes in
                      the market value of investments.
 
                      The funds also may enter into forward foreign currency
                      exchange contracts for hedging purposes. The net U.S.
                      dollar value of foreign currency underlying all
                      contractual commitments held by the funds, and the
                      resulting unrealized appreciation or depreciation, are
                      determined using foreign currency exchange rates from
                      independent pricing sources. The funds are subject to the
                      credit risk that the other party will not complete the
                      obligations of the contract.
 
                      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 to a joint 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.
                      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, GAINS AND LOSSES
                      Income, expenses (other than class-specific expenses) and
                      realized and unrealized gains and losses 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.
 
                      CONCENTRATION OF RISK
                      Investments in countries with limited or developing
                      capital markets may involve greater risks than investments
                      in more developed markets, and the prices of such
                      investments may be volatile. The consequences of
                      political, social or economic changes in these markets may
                      have disruptive effects on the market prices of the funds'
                      investments and the income they generate, as well as the
                      funds' ability to repatriate such amounts.
 
                      USE OF ESTIMATES
                      The preparation of financial statements in conformity with
                      generally accepted accounting principles requires
                      management to make estimates and assumptions that affect
                      the reported amounts in the financial statements. Actual
                      results could differ from these estimates.

(6) EXPENSES
 ................................
                      INVESTMENT MANAGEMENT FEE
                      The company has entered into an investment management
                      agreement with Piper Capital Management Incorporated
                      (Piper Capital) under which Piper Capital manages the
                      fund's assets and furnishes related office facilities,
                      equipment, research and personnel. The agreement requires
                      the fund to pay Piper Capital a monthly fee based on
                      average daily net assets. For Emerging Markets Growth Fund
                      the fee is equal to an annual rate of 1% of the fund's
                      average daily net assets. For Pacific-European Growth
                      Fund, the fee is equal to an annual rate of 1% of the
                      first $100 million in average daily net assets, 0.875% of
                      the next $100 million and 0.75% of the net assets in
                      excess of $200 million. For the six months ended March 31,
                      1998, the effective management fees paid by Emerging
                      Markets Growth Fund and Pacific-European Growth Fund
                      (including the performance adjustment described below)
                      were 1.00% and 0.82%, respectively, on an annual basis.
 
                      Since April 1991, the basic fee for Pacific-European
                      Growth Fund has been subject to a performance adjustment.
                      The adjustment is computed monthly by comparing the
                      performance of the Class A shares of the fund relative to
                      the Morgan Stanley Capital International EAFE Index, over
                      the preceding 12 month period. For each percentage point
                      the Class A shares of the fund outperform or underperform
                      the EAFE Index the monthly fee is increased or decreased
                      by 0.05% (on an annual basis) up to a maximum of 0.25% (on
                      an annual basis) of the fund's average daily net assets.
                      During the six months ended March 31, 1998, the
                      performance adjustment decreased the management fee by
                      $64,836.
 
                      Edinburgh Fund Managers plc has been retained by Piper
                      Capital as the subadvisor of Pacific-European Growth Fund
                      and is paid a fee equal to 65% of the basic investment
                      management fee plus

                      Managers plc has entered into an expense reimbursement
                      agreement with the advisor under which it pays the advisor
                      a monthly fee equal to 10% of the basic investment
                      management fee. This 10% fee is a reimbursement to the
                      advisor for certain expenses it bears in connection with
                      the administration of Pacific-European Growth Fund.
                      Edinburgh Fund Managers plc has also been retained by
                      Piper Capital as the subadvisor of Emerging Markets Growth
                      Fund and is paid a fee equal to 0.50% of the fund's
                      average daily net assets.
 
                      DISTRIBUTION AND SERVICE FEES
                      Each fund also pays Piper Jaffray fees accrued daily and
                      paid quarterly for providing shareholder services and
                      distribution-related services. The fees for each class,
                      which are being voluntarily limited for Class A for the

                      OTHER FEES AND EXPENSES
                      In addition to the investment management, distribution and
                      shareholder account servicing fees, the fund is
                      responsible for paying most other operating expenses,
                      including: outside directors' fees and expenses; custodian
                      fees; registration fees; printing and shareholder reports;
                      transfer agent fees and expenses; legal, auditing and
                      accounting services; insurance; interest; taxes and other
                      miscellaneous expenses. For the year ending September 30,
                      1998, Piper Capital voluntarily limited total fees and
                      expenses for Emerging Markets Growth Fund to annual rates
                      of 2.00% and 2.67% of average daily net assets
                      attributable to such shares for Class A and Class B,
                      respectively.

                      Expenses paid indirectly represent a reduction of

(7) CAPITAL LOSS
    CARRYOVER
 ................................
                      For federal income tax purposes, the following funds had
                      capital loss carryovers at September 30, 1997, which, if
                      not offset by subsequent capital gains, will expire on the
                      funds' fiscal year-ends as indicated below. It is unlikely
                      the board of directors will authorize a distribution of
                      any net realized capital gains until the available capital
                      loss carryovers have been offset or expire.
 
                      Utilization of the capital loss carryovers is limited to
                      $820,258 and $1,065,056 per year for Emerging Markets
                      Growth Fund and Pacific-European Growth Fund,
                      respectively.

(8) PENDING
    ACQUISITION
 ................................
                      On December 15, 1997, Piper Jaffray Companies Inc., the
                      parent company of the funds' investment advisor, announced
                      that it had entered into an agreement to be acquired by
                      U.S. Bancorp. It is anticipated that this acquisition will
                      be completed in the second quarter of 1998, subject to
                      regulatory approval, the approval of Piper Jaffray
                      Companies shareholders and the satisfaction of customary
                      closing conditions.
 
                      U.S. Bancorp is a multi-state bank holding company
                      headquartered in Minneapolis, Minnesota with a geographic
                      service area spanning 17 states. As of December 31, 1997,
                      U.S. Bancorp was the 15th largest U.S. commercial bank
                      holding company, with assets of nearly $71.3 billion. U.S.
                      Bank National Association ("U.S. Bank"), a wholly owned
                      subsidiary of U.S. Bancorp, currently acts as the
                      investment advisor to 32 mutual funds (the "First American
                      Funds"). As of December 31, 1997, U.S. Bank, acting
                      through its First American Asset Management group, managed
                      more than $55 billion in assets, including approximately
                      $20.5 billion in assets of the First American Funds.
 
                      Effective as of the date of the acquisition, SEI
                      Investments Distribution Company will assume the role of
                      the principal distributor for the funds.
 
                      Under the Investment Company Act of 1940, as amended (the
                      "1940 Act"), consummation of the acquisition of Piper
                      Jaffray Companies by U.S. Bancorp will result in the
                      assignment and automatic

                      termination of the funds' investment advisory agreements
                      with Piper Capital Management Incorporated. The 1940 Act
                      requires that any new investment advisory agreements for
                      the funds be approved by the funds' board of directors and
                      shareholders.
 
(9) SUBSEQUENT EVENTS
 ................................
                      CLASS B AND Y SHARES NO LONGER OFFERED
                      Effective April 21, 1998, the funds will no longer offer
                      Class B shares. Any outstanding Class B shares of a series
                      will be automatically converted to Class A shares of the
                      same series as of the close of business on April 27, 1998.
                      No contingent deferred sales charges or other fees will be
                      imposed in connection with this conversion.
 
                      Effective April 15, 1998, Pacific-European Growth Fund
                      will no longer offer Class Y shares.
 
                      FUND CONVERSION
                      In connection with the acquisition of Piper Jaffray
                      Companies Inc. by U.S. Bancorp, the funds' board of
                      directors has recommended that the funds be merged into
                      mutual funds managed by First American Asset Management, a
                      division of U.S. Bank. The proposed fund mergers require
                      shareholder approval and proxy statements requesting
                      shareholder votes will be mailed in May 1998. If approved,
                      the mergers are expected to occur on or about July 31,
                      1998.

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1998, SMALL COMPANY GROWTH FUND CLASS A
DELIVERED A 5.72%* TOTAL RETURN WITH ALL DISTRIBUTIONS REINVESTED BUT NOT
INCLUDING THE SALES CHARGE. This compares to the Standard & Poor's SmallCap 600
Index,+ which returned 7.63% during the period, and the 5.32% gain of the Lipper
Small Cap Funds Average.** Your fund's portfolio includes stocks of companies
that are more growth-oriented than those in the S&P SmallCap 600 (which includes
both growth and value stocks), and we believe this is the principal reason for
its underperformance of the S&P benchmark.

THE RUSSELL 2000 GROWTH INDEX, WHICH REPRESENTS A GROWTH INVESTMENT STYLE
SIMILAR TO THAT OF SMALL COMPANY GROWTH FUND, RETURNED 2.73% DURING THE
REPORTING PERIOD. We believe the fund's solid performance during the period is a
result of our process of maintaining a diverse portfolio of quality small
companies with the potential for significant growth. Even though the market was
volatile during the period, we remained focused on our strategy - and as a
result, the fund was well positioned when the market rebounded.

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Safety of principal is not guaranteed. THE
FUND OPERATED AS EQUITY STRATEGY FUND UNTIL SEPTEMBER 13, 1996, WITH AN
OBJECTIVE OF HIGH TOTAL INVESTMENT RETURN CONSISTENT WITH PRUDENT INVESTMENT
RISK. Stocks of small companies are more volatile than stocks of larger
companies. They often involve higher risks because small companies lack the
management expertise, financial resources, product diversification and
competitive strengths of larger companies. See the prospectus for more complete
information regarding risks. During most periods, the fund's advisor waived or
paid certain expenses and/or the fund's distributor voluntarily waived certain
12b-1 fees. Without waivers, returns would have been lower.

All fund and benchmark returns include reinvested distributions.

DURING FOURTH QUARTER 1997, SMALL-CAP STOCK PRICES FELL AS THE ASIAN ECONOMIC
CRISIS SPURRED AN INVESTOR FLIGHT TO SAFETY. The year ended with small-cap
stocks down for the quarter (but up considerably for the year), due to investor
concern that Asia's troubles might slow earnings growth in the United States.
However, sentiment changed dramatically, and investors returned to small-cap
stocks in late January, as the U.S. economy performed above expectations. This
strength continued throughout the remainder of the period, resulting in one of
the strongest quarters for stocks in some time.

OUR INVESTMENTS IN A VARIETY OF INDUSTRIES DID WELL DURING THE SIX-MONTH PERIOD.
Positive performers included Pier 1 Imports (1.1% of the fund's total assets as
of March 31, 1998) and Stage Stores (1.9%) in the retail industry; Commerce
Bancorp (1.3%) and Financial Federal Corp. (1.3%) in the financial sector,***
Control Devices (0.8%) in the capital goods area, and Novoste (0.6%), Cyberonics
(1.0%) and Express Scripts (1.5%) in the health care sector. Although the health
care and technology sectors provided mixed performance during the period, our
holdings in these areas performed well overall.

TAKING ADVANTAGE OF PRICE WEAKNESS IN THE TECHNOLOGY SECTOR, WE BOUGHT SEVERAL
STOCKS THAT WE BELIEVE OFFER BRIGHT PROSPECTS. These include P-COM Inc. (1.5%)
and PMC-Sierra (1.7%), which focus on telecommunications and communications
infrastructure; Made2Manage Systems (0.9%), which is an application software
provider; and Applied Micro Circuits (0.6%). Other issues we added included C.H.
Robinson Worldwide (0.8%), a transportation and logistics company, and Kuhlman
Corp. (0.5%), which provides products for utility companies.

SMALL COMPANY GROWTH FUND  (CONTINUED)

THE FUND ALSO SOLD SELECTED STOCKS AS WE FELT APPROPRIATE. These names included
semiconductor companies Anadigics and PRI Automation (due to their difficult
operating environment), as well as commercial services businesses Watso Inc. (a
heating/air conditioning supplier hurt by unfavorable weather conditions) and
Wilmar Industries (because we no longer see a catalyst that will lift the stock
further).

EVEN WITH THE MARKET'S RECENT STRONG PERFORMANCE, VALUATIONS*** REMAIN 
ATTRACTIVE FOR SMALL-CAP STOCKS. This is particularly true relative to larger 
stocks. The valuations are similar; however, earnings growth is slowing for 
many larger companies. Until recently, investors have not needed to shift to 
smaller companies to achieve above average earnings growth.

Thank you for your investment in Small Company Growth Fund. We are dedicated to
providing you with superior service and look forward to helping you achieve your
investment goals.


Sincerely,


/s/ Sandra Shrewsbury

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1998, EMERGING GROWTH FUND CLASS A 
DELIVERED AN 11.26%* TOTAL RETURN WITH ALL DISTRIBUTIONS REINVESTED BUT NOT 
INCLUDING THE SALES CHARGE. This compares to the Standard & Poor's MidCap 400 
Index,** which returned 11.94% during the period, and the 8.41% gain of the 
Lipper Mid Cap Funds Average.+

THE RUSSELL MID-CAP GROWTH INDEX, WHICH REPRESENTS AN INVESTMENT STYLE SIMILAR
TO THAT OF EMERGING GROWTH FUND, RETURNED 8.85% DURING THE REPORTING PERIOD. We
believe the fund's solid performance during the period is a result of our
process of maintaining a diverse portfolio of quality mid-sized companies with
the potential for significant growth. Even though the market was volatile during
the period, we remained focused on our strategy - and as a result, the fund was
well positioned when the market rebounded.

MID-CAP STOCK PRICES FELL DURING THE LAST MONTHS OF 1997 AS THE ASIAN ECONOMIC
CRISIS PROMPTED AN INVESTOR FLIGHT TO SAFETY. The year ended with mid-cap stocks
down for the quarter (but up considerably for the year), due to investor concern
that Asia's troubles might slow earnings growth in the United States. However,
sentiment changed dramatically, and investors returned to mid-cap stocks in late
January,

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Safety of principal is not guaranteed. Stocks
of mid-sized companies are more volatile than stocks of larger companies. These
companies may have limited product lines and operating histories and may rely on
narrower management teams. See the prospectus for more complete information
regarding risks. During most periods, the fund's advisor waived or paid certain
expenses and/or the fund's distributor voluntarily waived certain 12b-1 fees.
Without waivers, class A returns would have been lower.

All fund and benchmark returns include reinvested distributions.

as the U.S. economy performed above expectations. The strength continued
throughout the remainder of the period, resulting in one of the strongest
quarters for equities in some time.

THE FUND'S HOLDINGS IN THE FINANCIAL SECTOR*** LED THE WAY DURING THIS REPORTING
PERIOD, PARTICULARLY IN THE FOURTH QUARTER OF 1997. The financial sector has
been a strong performer for many years, and we believe its current values
generally reflect future prospects. For that reason, we have reduced our
financial industry weighting. Consumer cyclical stocks also were very strong
during the period, particularly our investments in value retailers such as
Dollar General (1.6% of the fund's total assets as of March 31, 1998) and Kohls
(1.1%). In other industries, Danaher (2.2%, a capital goods company), Cintas
(1.0%, uniform leasing) and Chancellor Media (1.9%) provided favorable results.

TECHNOLOGY AND HEALTH CARE STOCKS PROVIDED MIXED RESULTS DURING THE FOURTH
QUARTER OF 1997 BUT PICKED UP IN 1998. Our strong technology performers included
Sunguard Data Systems (1.4%) and Vantive (1.1%). In consumer non-durables, our
holdings of Rexall Sundown (1.1%, a vitamin producer) did well, as did health
care company Health Management Association (1.2%, hospital management). We are
selectively adding to our technology holdings as opportunities present
themselves. Recent additions have been in telecommunications (Tellabs Inc.,
1.2%, Advanced Fibre Communications, 0.6%, and CIENA, 1.0%) and software (Legato
Systems, 0.9%). We sold positions in Phycor and Genesis Health Ventures, two
health care services companies, to focus on health care areas with greater
earnings visibility and fewer external threats.

ENERGY STOCKS PERFORMED WELL DURING THE FOURTH QUARTER BUT WEAKENED IN EARLY 
1998. We believe the current weakness is due to low oil prices caused by 
weakening demand in Asia and a warm "El Nino" winter in the Northern 
Hemisphere. We are underweighted*** in the energy sector, compared to the 
fund's benchmark, as well as in slower-growth industries such as basic 
materials and consumer durable goods.

EVEN WITH THE MARKET'S RECENT STRONG PERFORMANCE, VALUATIONS*** REMAIN 
ATTRACTIVE FOR MID-CAP STOCKS. This is particularly true relative to larger 
stocks. The valuations are similar; however, earnings growth is slowing for 
many larger companies. Until recently, investors have not needed to shift to 
smaller companies to achieve above average earnings growth.

Thank you for your investment in Emerging Growth Fund. We are dedicated to
providing you with superior service and look forward to helping you achieve your
investment goals.

DEAR SHAREHOLDERS:

FOR THE SIX MONTHS ENDED MARCH 31, 1998, GROWTH FUND CLASS A RETURNED 6.52%*
WHICH INCLUDES REINVESTED DISTRIBUTIONS BUT NOT THE FUND'S SALES CHARGE. This
return is less than the 11.55% return for the Lipper Growth Funds Average+  and
the 17.21% return for the S&P 500 Index, **the fund's benchmark. We are not
happy with these results and have taken steps to improve performance.

THE DOMINANT THEME IN THE STOCK MARKET OVER THE LAST SIX MONTHS HAS BEEN THE 
ECONOMIC FALLOUT FROM THE FINANCIAL CRISIS IN SOUTHEAST ASIA.  This economic 
fallout has had a negative effect on the sales and earnings growth of 
economically sensitive sectors*** such as technology, basic materials and 
energy. However, the stock market has staged a strong advance from its lows 
in October, driven primarily by large growth stocks.

OVER THE PAST SIX MONTHS, THE FUND'S PERFORMANCE HAS BEEN NEGATIVELY AFFECTED BY
ITS OVERWEIGHTING*** IN TECHNOLOGY AND ENERGY. Long-term, we still like these
areas, and as the situation in Asia stabilizes we would expect the stock
performance in these sectors to improve.

THE FUND BENEFITED FROM ITS INVESTMENTS IN THE FINANCE SECTOR. Our large
holdings in Norwest (4.3% of the fund's total assets as of March 31, 1998),
American International Group (3.9%) and the Federal

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Safety of principal is not guaranteed. During
most periods, the fund's advisor waived or paid certain expenses and/or the
fund's distributor voluntarily waived certain 12b-1 fees. Without waivers, class
A returns would have been lower.

All fund and benchmark returns include reinvested distributions.

GROWTH FUND  (CONTINUED)

BRENT MELLUM, CFA
assists with the management of Growth Fund. He has four years of financial
experience.
- --------------------------------------------------------------------------------


National Mortgage Association (3.3%) had a strong positive effect on 
performance. Other strong contributors included Magna International (4.0%), 
Gap Inc. (2.3%) and AirTouch Communications (5.0%).

RECOGNIZING THE NEED TO IMPROVE THE PERFORMANCE OF THE FUND, WE HAVE DEDICATED
MORE RESOURCES TO ITS MANAGEMENT. The results so far are encouraging, even
though they have not yet produced a significant improvement in performance. We
have focused our efforts on adding high-quality growth stocks to the portfolio.
Recent additions include Worldcom (1.7%), Albertson's (1.4%), United Healthcare
(2.0%), McDonald's (2.2%), Mattel (1.0%) and Masco Corp. (1.1%). We see
investment opportunities in growth stocks outside the mega-cap stock arena,
since we believe growth rates for the somewhat smaller stocks are higher and
prices are more reasonable.

Thank you for your investment in Growth Fund. We appreciate your confidence, and
we want to assure you that we remain committed to providing quality management
services.


Sincerely,



/s/ Steve Markusen                 /s/ Brent Mellum

                      CLASS A:
                      - Subject to a front-end sales charge
 
                      - Lower distribution and service fees than Class B
 
                      CLASS B:
                      - No front-end sales charge
 
                      - Subject to a contingent deferred sales charge upon
                      redemption
 
                      - Higher distribution and service fees than Class A
 
                      - Automatic conversion to Class A shares at the beginning
                      of the sixth calendar year after issuance
 
                      CLASS Y:
                      - Requires a minimum initial investment of $1 million
 
                      - No front-end or contingent deferred sales charges
 
                      - No distribution and service fees
 
                      The classes of shares have the same rights and are
                      identical in all respects except that each class bears
                      different distribution expenses, has exclusive voting
                      rights with respect to matters affecting that class and
                      has different exchange privileges.
 
                      Small Company Growth Fund invests primarily in common
                      stocks of small-capitalization companies believed to
                      possess superior growth potential.
 
                      Emerging Growth Fund invests primarily in common stocks
                      and securities convertible into common stocks of emerging
                      growth companies.
 
                      Growth Fund invests primarily in a broadly diversified
                      portfolio of stocks or securities convertible into or
                      carrying rights to buy common stocks.

                      Portfolio securities for which market quotations are
                      readily available are valued at current market value. If
                      market quotations or valuations are not readily available,
                      or if such quotations or valuations are believed to be

                      valued according to procedures adopted by the funds' board
                      of directors in good faith at "fair value", that is, a
                      price that the fund might reasonably expect to receive for
                      the security or other asset upon its current sale.
 
                      Pricing services value domestic and foreign equity
                      securities (and occasionally fixed-income securities)
                      traded on a securities exchange or Nasdaq at the last
                      reported sale price, up to the time of valuation. If there
                      are no reported sales of a security on the valuation date,
                      it is valued at the mean between the published bid and
                      asked prices reported by the exchange or Nasdaq. If there
                      are no sales and no published bid and asked quotations for
                      a security on the valuation date or the security is not
                      traded on an exchange or Nasdaq, the pricing service may
                      obtain market quotations directly from broker-dealers.
 
                      Securities transactions are accounted for on the date
                      securities are purchased or sold. Realized gains and
                      losses are calculated on the identified-cost basis.
                      Dividend income is recognized on the ex-dividend date and
                      interest income, including amortization of bond discount
                      and premium, is recorded on an accrual basis.
 
                      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.
 
                      Net investment income and net realized gains (losses) may
                      differ for financial statement and tax purposes primarily
                      because of losses deferred due to "wash sale"
                      transactions. The character of distributions made during
                      the year from net investment income or net realized gains
                      may differ from its ultimate characterization for federal
                      income tax purposes. In addition, due to the timing of
                      dividend distributions, the fiscal year in which amounts
                      are distributed may differ from the year that the income
                      or realized gains (losses) were recorded by the funds.
 
                      ALLOCATION OF INCOME, EXPENSES AND GAINS(LOSSES)
                      Income, expenses (other than class-specific expenses) and
                      realized and unrealized gains and losses 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.
 
                      DISTRIBUTIONS TO SHAREHOLDERS
                      Distributions to shareholders from net investment income
                      will be declared separately for each class and paid at
                      least annually. Net realized gains distributions, if any,
                      will be made at least annually. Distributions are payable
                      in cash or reinvested in additional shares of the same
                      class.

                      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 to a joint 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.
                      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.
 
                      USE OF ESTIMATES
                      The preparation of financial statements in conformity with
                      generally accepted accounting principles requires
                      management to make estimates and assumptions that affect
                      the reported amounts in the financial statements. Actual
                      results could differ from these estimates.

(6) PENDING
    ACQUISITION
 ................................
                      On December 15, 1997, Piper Jaffray Companies Inc., the
                      parent company of the funds' investment advisor, announced
                      that it had entered into an agreement to be acquired by
                      U.S. Bancorp. It is anticipated that this acquisition will
                      be completed in the second quarter of 1998, subject to
                      regulatory approval, the approval of Piper Jaffray
                      Companies shareholders and the satisfaction of customary
                      closing conditions.
 
                      U.S. Bancorp is a multi-state bank holding company
                      headquartered in Minneapolis, Minnesota with a geographic
                      service area spanning 17 states. As of December 31, 1997,
                      U.S. Bancorp was the 15th largest U.S. commercial bank
                      holding company, with assets of nearly $71.3 billion. U.S.
                      Bank National Association ("U.S. Bank"), a wholly owned
                      subsidiary of U.S. Bancorp, currently acts as the
                      investment advisor to 32 mutual funds (the "First American
                      Funds"). As of December 31, 1997, U.S. Bank, acting
                      through its First American Asset Management group, managed
                      more than $55 billion in assets, including approximately
                      $20.5 billion in assets of the First American Funds.
 
                      Effective as of the date of the acquisition, SEI
                      Investments Distribution Company will assume the role of
                      the principal distributor for the funds.
 
                      Under the Investment Company Act of 1940, as amended (the
                      "1940 Act"), consummation of the acquisition of Piper
                      Jaffray Companies by U.S. Bancorp will result in the
                      assignment and automatic termination of the funds'
                      investment advisory agreements with Piper Capital
                      Management Incorporated. The 1940 Act requires that any
                      new investment advisory agreements for the funds be
                      approved by the funds' board of directors and
                      shareholders.
 
(7) SUBSEQUENT EVENTS
 ................................
                      CLASS B SHARES NO LONGER OFFERED
                      Effective April 21, 1998, the funds will no longer offer
                      Class B shares. Any outstanding Class B shares of a fund
                      will be automatically converted to Class A shares of the
                      same fund as of the close of business on April 27, 1998.
                      No contingent deferred sales charges or other fees will be
                      imposed in connection with this conversion.
 
                      FUND CONVERSION
                      In connection with the acquisition of Piper Jaffray
                      Companies Inc. by U.S. Bancorp, the funds' board of
                      directors has recommended that the funds be merged into
                      mutual funds managed by First American Asset Management, a
                      division of U.S. Bank. The proposed fund mergers require
                      shareholder approval, and proxy statements requesting
                      shareholder votes will be mailed in May 1998. If approved,
                      the mergers are expected to occur on or about July 31,
                      1998.

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1998, GROWTH AND INCOME FUND CLASS A
RETURNED 11.72%,* WITH ALL DISTRIBUTIONS REINVESTED, BUT NOT INCLUDING THE
FUND'S SALES CHARGE. These results were below the 12.49% return for the Lipper
Growth and Income Funds Average.+ The stock market continued its upward move
with most major indexes recording strong gains. High levels of volatility
characterized the market during the last six months as the Dow Jones Industrial
Average dropped more than 500 points in mid-October but went on to record levels
as the first quarter of 1998 ended. The fund achieved excellent results from
several large holdings and its exposure to interest rate sensitive sector*** of
the market. However, poor relative results from the fund's energy holdings
caused its performance to lag that of its Lipper peer group.

STRONG APPRECIATION FROM SEVERAL LARGE HOLDINGS IN THE FUND HAD A POSITIVE
IMPACT ON PERFORMANCE.  Ford Motor Co. (3.6% of the fund's total assets as of
March 31, 1998) posted higher earnings due to improved profitability at its
North American automotive unit. The low valuation of Ford's automotive assets,
along with its strong earnings improvement, allowed the stock to sharply
appreciate during the period. AirTouch Communications (2.9%) maintained its
leadership position in wireless communications by posting subscriber additions,
cash flow, profit margins and earnings

that were above consensus expectations. Carnival Corp. (1.8%), the leading
cruise operator, was also a strong performer due to excellent pricing trends and
high occupancy levels that led to good earnings growth. These stocks highlight
the fund's investment process of identifying attractively valued companies with
above average earnings and dividend growth prospects.

THE FUND WAS OVERWEIGHTED IN SECTORS THAT ARE SENSITIVE TO INTEREST RATES, WHICH
ALSO HAD A POSITIVE IMPACT ON PERFORMANCE. Financial stocks continued to perform
well as lower interest rates highlighted attractive valuations.*** Norwest Corp.
(2.7%), Federal National Mortgage Corp. (3.1%) and Associates First Capital
Corp. (1.6%) recorded strong gains due to above average earnings growth. The
utility sector benefited from its position as a safe haven during the volatile
fourth quarter of 1997. Telecommunications utilities such as BellSouth Corp.
(2.1%) and GTE Corp. (2.4%) and electric utility FPL Group (2.5%) registered
price appreciation and provided the fund with income from their above average
dividends.

THE FUND'S OVERWEIGHTED*** POSITION IN ENERGY STOCKS HAMPERED PERFORMANCE DURING
THE PERIOD.  Short-term factors, including a slowdown in Asian demand and a
warmer than normal winter in North America, resulted in a near-term excess
supply of oil in the world's energy markets. This caused the price of oil to
fall dramatically, reducing earnings expectations for the group as a whole,
which led to poor stock performance. Oil service companies like Schlumberger
(1.7%) and Baker Hughes (1.3%) performed poorly as low oil prices lowered growth
prospects for 1998.

LONGER TERM, WE ARE STILL POSITIVE ON THE SUPPLY/DEMAND OUTLOOK FOR OIL. We
anticipate steady demand growth over the next few years, which will ease the
current oversupply. Given this viewpoint, we

believe major integrated oil companies such as Exxon (2.2%) and Texaco (2.4%)
will benefit from rising production levels and higher utilization rates that
should improve profit margins and earnings. Both companies are attractively
valued and provide income to the fund from their above average dividend
payments. We also think oil service companies, primarily Schlumberger, are
attractively valued given the strong earnings growth we anticipate over the next
several years.

MODERATE ECONOMIC GROWTH AND LOW INFLATION WILL CONTINUE TO PROVIDE AN EXCELLENT
BACKDROP FOR THE EQUITY MARKET. However, we remain cautious over the near term
due to increased volatility and high valuations in certain sectors of the
market. We believe the fund offers investors a diversified portfolio of large,
high-quality companies. Our investment process continues to focus on identifying
attractively valued companies with above-average earnings and dividend growth
potential or companies that are undervalued in the marketplace. We believe this
process will deliver consistent, competitive performance and fulfill the fund's
investment objective of current income and growth of capital and income.

Thank you for your investment in Growth and Income Fund. We appreciate the
opportunity to manage your assets and help you pursue your long-term investment
goals.

Fund. He has 19 years of financial experience.

DEAR SHAREHOLDERS:

FOR THE SIX MONTHS ENDED MARCH 31, 1998, BALANCED FUND CLASS A PROVIDED A 
7.85%* TOTAL RETURN WITH ALL DISTRIBUTIONS REINVESTED BUT NOT INCLUDING THE 
SALES CHARGE. The fund fell short of the 8.92% gain reported by the Lipper 
Balanced Funds Average,++ mainly because we held a smaller proportion of 
stocks (slightly more than 50%) than the average (about 60%, according to our 
estimates). We continued our conservative stock position because U.S. 
equities appeared fully valued, if not expensive, and bonds showed better 
value. As it turned out, stocks resumed their rapid ascent in the first 
quarter, outperforming bonds by a considerable margin. During the same time 
period, the Lehman Brothers Government Corporate Index** and the Standard & 
Poor's 500 Index+ advanced 4.77% and 17.21%, respectively.

THE BOND PORTION OF YOUR FUND PERFORMED WELL, DUE TO A MODEST 
OVERWEIGHTING*** IN CORPORATE AND MORTGAGE-BACKED SECURITIES. Our bond 
portfolio's effective duration*** was essentially the same as that of its 
benchmark.*** Changes in the fund's bond holdings were minor during the 
period. We focused on the purchase and sale of select Treasury securities. 
Overall, we continued our existing strategy of emphasizing as much income as 
prudent.

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
your investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Neither safety of principal nor stability of
income is guaranteed. During most periods, the fund's advisor waived or paid
certain expenses and/or the fund's distributor voluntarily waived certain 12b-1
fees. Without waivers, returns would have been lower.

All fund and benchmark returns include reinvested distributions.

CERTAIN PORTIONS OF THE EQUITY COMPONENT OF YOUR FUND POSTED A STRONG RETURN
DURING THE PERIOD, AND THE FUND CONTINUED TO BENEFIT FROM POSITIONS IN COMPANIES
SUCH AS COCA-COLA CO. (0.6% OF TOTAL ASSETS AS OF MARCH 31, 1998), GENERAL
ELECTRIC (1.5%) AND MERCK & CO., INC. (2.0%).  The U.S. stock market slumped
during the fourth quarter as investors worried about the effects of the Asian
economic crisis on earnings growth. But the U.S. economy continued its strong
growth in early 1998, resulting in one of the strongest quarters for stocks in
some time. During the period, we added several quality growth stocks to the
portfolio, including McDonald's (1.2%), Albertson's (0.6%), United Healthcare
(1.0%), Mattel Inc. (0.5%) and WorldCom Inc. (0.65). These additions already
have had a positive impact on the fund's performance.

THE FUND'S EQUITY PERFORMANCE WAS HELD BACK BY OUR HOLDINGS IN THE ENERGY SECTOR
- -- PARTICULARLY THE ENERGY SERVICE INDUSTRY. Our investments in this industry
have been strong performers over the last three years, and we believe the
current weakness is due to low oil prices caused by weakening demand in Asia and
a warm "El Nino" winter in the Northern Hemisphere. OPEC has recently taken
steps to reduce oil production, and that has stabilized prices. Typically, oil
prices have rebounded from such lows within about six months. We believe we are
in a long-term capital spending cycle for oil service companies and intend to
maintain our position in these stocks.

Thank you for investing in Balanced Fund. We appreciate the opportunity to help
you manage your assets.

(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 Growth and Income Fund
                      and Balanced 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.
 
                      The funds commenced offering Class B shares and Growth and
                      Income Fund commenced offering Class Y 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:
                      - Subject to a front-end sales charge
 
                      - Lower distribution and service fees than Class B
 
                      CLASS B:
                      - No front-end sales charge
 
                      - Subject to a contingent deferred sales charge upon
                      redemption
 
                      - Higher distribution and service fees than Class A
 
                      - Automatic conversion to Class A shares at the beginning
                      of the sixth calendar year after issuance
 
                      CLASS Y:
                      - Requires a minimum initial investment of $1 million
 
                      - No front-end or contingent deferred sales charges
 
                      - No distribution and service fees
 
                      The classes of shares have the same rights and are
                      identical in all respects except that each class bears
                      different distribution expenses, has exclusive voting
                      rights with respect to matters affecting that class and
                      has different exchange privileges.
 
                      Growth and Income Fund invests primarily in stocks of
                      large, established companies that appear undervalued and
                      potentially offer long-term dividend and earnings growth.
                      The fund may also invest in debt securities including U.S.
                      government securities and nonconvertible preferred stock.
 
                      Balanced Fund invests in both common stocks and fixed
                      income securities that appear to have some potential for
                      capital appreciation.

    ACCOUNTING
    POLICIES
 ................................
                      INVESTMENTS IN SECURITIES
                      Portfolio securities for which market quotations are
                      readily available are valued at current market value. If
                      market quotations or valuations are not available, or if
                      such quotations or valuations are believed to be
                      inaccurate, unreliable or not reflective of market value,
                      portfolio securities are valued

- --------------------------------------------------------------------------------
                      according to procedures adopted by the funds' board of
                      directors in good faith at "fair value", that is, a price
                      that the fund might reasonably expect to receive for the
                      security or other asset upon its current sale.
 
                      The current market value of certain fixed income
                      securities is provided by an independent pricing service.
                      Fixed income securities for which prices are not available
                      from an independent pricing service but where an active
                      market exists are valued using market quotations obtained
                      from one or more dealers that make markets in the
                      securities or from a widely-used quotation system.
                      Short-term securities with maturities of 60 days or less
                      are valued at amortized cost, which approximates market
                      value.
 
                      Exchange-traded options are valued at the last sales price
                      on the exchange prior to the time when assets are valued.
                      If no sales were reported that day, the options will be
                      valued at the mean between the current closing bid and
                      asked prices. Over-the-counter options are valued using
                      market quotations obtained from broker-dealers. Financial
                      futures are valued at the last settlement price
                      established each day by the board of trade or exchange on
                      which they are traded.
 
                      Pricing services value domestic and foreign equity
                      securities (and occasionally fixed-income securities)
                      traded on a securities exchange or Nasdaq at the last
                      reported sale price, up to the time of valuation. If there
                      are no reported sales of a security on the valuation date,
                      it is valued at the mean between the published bid and
                      asked prices reported by the exchange or Nasdaq. If there
                      are no sales and no published bid and asked quotations for
                      a security on the valuation date or the security is not
                      traded on an exchange or Nasdaq, the pricing service may
                      obtain market quotations directly from broker-dealers.
 
                      Securities transactions are accounted for on the date
                      securities are purchased or sold. Realized gains and
                      losses are calculated on the identified-cost basis.
                      Dividend income is recognized on the ex-dividend date and
                      interest income, including amortization of bond discount
                      and premium, is recorded on an accrual basis.
 
                      OPTIONS TRANSACTIONS
                      For hedging purposes, the funds may buy and sell put and
                      call options, write covered call options on portfolio
                      securities and write cash-secured puts. The risk in
                      writing a call option is that the funds give up the
                      opportunity of profit if the market price of the security
                      increases. The risk in writing a put option is that the
                      funds may incur a loss if the market price of the security
                      decreases and the option is exercised. The risk in buying
                      an option is that the funds pay a premium whether or not
                      the option is exercised. The funds also have the
                      additional risk of not being able to enter into a closing
                      transaction if a liquid secondary market does not exist.
 
                      Option contracts are valued daily and unrealized
                      appreciation or depreciation is recorded. The funds will
                      realize a gain or loss upon expiration or closing of the
                      option transaction. When an option is exercised, the
                      proceeds on the sale of a written call option, the
                      purchase cost of a written put option, or the cost of a
                      security for purchased put and call options is adjusted by
                      the amount of premium received or paid.

                      FUTURES TRANSACTIONS
                      For hedging purposes, the funds may buy and sell financial
                      futures contracts and related options. Risks of entering
                      into futures contracts and related options include the
                      possibility that there may be an illiquid market and that
                      a change in the value of the contract or option may not
                      correlate with changes in the value of the underlying
                      securities.
 
                      Upon entering into a futures contract, the funds are
                      required to deposit either cash or securities in an amount
                      (initial margin) equal to a certain percentage of the
                      contract value. Subsequent payments (variation margin) are
                      made or received by the funds each day. The variation
                      margin payments are equal to the daily changes in the
                      contract value and are recorded as unrealized gains and
                      losses. The funds recognize a realized gain or loss when
                      the contract is closed or expires.
 
                      SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
                      Delivery and payment for securities that have been
                      purchased by the funds on a when-issued or
                      forward-commitment basis can take place a month or more
                      after the transaction date. During this period, such
                      securities do not earn interest, are subject to market
                      fluctuation and may increase or decrease in value prior to
                      their delivery. The funds segregate, with their custodian,
                      assets with a market value equal to the amount of their
                      purchase commitments. The purchase of securities on a
                      when-issued or forward-commitment basis may increase the
                      volatility of the funds' net asset value if the funds make
                      such purchases while remaining substantially fully
                      invested. As of March 31, 1998, the funds had no
                      outstanding when-issued or forward-commitments.
 
                      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.
 
                      Net investment income and net realized gains (losses) may
                      differ for financial statement and tax purposes primarily
                      because of losses deferred due to "wash sale" and
                      "straddle" transactions.
 
                      The character of distributions made during the year from
                      net investment income or net realized gains may differ
                      from its ultimate characterization for federal income tax
                      purposes. In addition, due to the timing of dividend
                      distributions, the fiscal year in which amounts are
                      distributed may differ from the year that the income or
                      realized gains (losses) were recorded by the funds.
 
                      DISTRIBUTIONS TO SHAREHOLDERS
                      Distributions to shareholders from net investment income
                      are declared separately for each class and paid quarterly.
                      Net realized gains distributions, if any, will be made at
                      least annually. Distributions are payable in cash or
                      reinvested in additional shares of the same class.

                      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 to a joint 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.
                      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 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 make estimates and assumptions that affect
                      the reported amounts in the financial statements. Actual
                      results could differ from these estimates.

                      furnishes related office facilities, equipment, research
                      and personnel. The agreement requires each fund to pay
                      Piper Capital a monthly fee based on average daily net
                      assets. The fee for each fund is equal to an annual rate
                      of 0.75% of the first $100 million in net assets, 0.65% of
                      the next $200 million and decreasing percentages
                      thereafter to 0.50% of net assets in excess of $500
                      million. For the six months ended March 31, 1998, the
                      effective investment management fee paid by the funds was
                      0.72% and 0.75% on an annual basis for Growth and Income
                      Fund and Balanced Fund, respectively.
 
                      DISTRIBUTION AND SERVICE FEES
                      Each fund also pays Piper Jaffray fees accrued daily and
                      paid quarterly for providing shareholder services and
                      distribution-related services. The fees for each class,
                      which are being voluntarily limited for Class A for the
                      year ended September 30, 1998, are stated below as a

                      In addition to the investment management, distribution and
                      shareholder account servicing fees, each fund is
                      responsible for paying most other operating expenses

(6) PENDING
    ACQUISITION
 ................................
                      On December 15, 1997, Piper Jaffray Companies Inc., the
                      parent company of the funds' investment advisor, announced
                      that it had entered into an agreement to be acquired by
                      U.S. Bancorp. It is anticipated that this acquisition will
                      be completed in the second quarter of 1998, subject to
                      regulatory approval, the approval of Piper Jaffray
                      Companies shareholders and the satisfaction of customary
                      closing conditions.
 
                      U.S. Bancorp is a multi-state bank holding company
                      headquartered in Minneapolis, Minnesota with a geographic
                      service area spanning 17 states. As of December 31, 1997,
                      U.S. Bancorp was the 15th largest U.S. commercial bank
                      holding company, with assets of nearly $71.3 billion. U.S.
                      Bank National Association ("U.S. Bank"), a wholly owned
                      subsidiary of U.S. Bancorp, currently acts as the
                      investment advisor to 32 mutual funds (the "First American
                      Funds"). As of December 31, 1997, U.S. Bank, acting
                      through its First American Asset Management group, managed
                      more than $55 billion in assets, including approximately
                      $20.5 billion in assets of the First American Funds.
 
                      Effective as of the date of the acquisition, SEI
                      Investments Distribution Company will assume the role of
                      the principal distributor for the funds.
 
                      Under the Investment Company Act of 1940, as amended (the
                      "1940 Act"), consummation of the acquisition of Piper
                      Jaffray Companies by U.S. Bancorp will result in the
                      assignment and automatic termination of the funds'
                      investment advisory agreement with Piper Capital
                      Management Incorporated. The 1940 Act requires that any
                      new investment advisory agreement for the funds be
                      approved by the funds' board of directors and
                      shareholders.
 
(7) SUBSEQUENT EVENTS
 ................................
                      CLASS B SHARES NO LONGER OFFERED
                      Effective April 21, 1998, the funds will no longer offer
                      Class B shares. Any outstanding Class B shares of a fund
                      will be automatically converted to Class A shares of the
                      same fund as of the close of business on April 27, 1998.
                      No contingent deferred sales charges or other fees will be
                      imposed in connection with this conversion.
 
                      FUND CONVERSION
                      In connection with the acquisition of Piper Jaffray
                      Companies Inc. by U.S. Bancorp, the funds' board of
                      directors has recommended that the funds be merged into
                      mutual funds managed by First American Asset Management, a
                      division of U.S. Bank. The proposed fund mergers require
                      shareholder approval, and proxy statements requesting
                      shareholder votes will be mailed in May 1998. If approved,
                      the mergers are expected to occur on or about July 31,
                      1998.

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 1998, THE FUND ACHIEVED A TOTAL RETURN
OF 4.31%* WITH ALL DISTRIBUTIONS REINVESTED BUT NOT INCLUDING THE FUND'S SALES
CHARGE.  During the same period, the fund's benchmark,*** the Merrill Lynch 5-10
Year Treasury Index,** returned 5.22%, while the Lipper U.S. Mortgage Funds
Average+ gained 3.6%. The fund's monthly dividend remained stable at between 4.5
cents and 4.9 cents per share over the six-month reporting period.

THE FUND WAS POSITIONED TO BENEFIT FROM AN EXPECTED DECLINE IN LONG-TERM
INTEREST RATES, WHICH DID HAPPEN DURING THE REPORTING PERIOD. Entering the
fourth quarter of 1997, the fund's effective duration*** was 5.5 years, or about
two years longer than our estimate of the effective duration of the average
mortgage fund within the Lipper category. (We discuss effective duration in
greater detail below.) During the period, we made no significant changes to the
fund's duration. This strategy reflected our view that long-term interest rates
were likely to exhibit stability, along with the high priority that the fund
continues to place on generating current income.

THE FUND'S PERFORMANCE RELATIVE TO ITS LIPPER PEER GROUP IS IN PART DUE TO ITS
LONGER EFFECTIVE DURATION. In a falling interest-rate environment such as the
one that characterized the reporting period, longer-duration portfolios will
typically outperform as bond prices appreciate. Relative to the fund's
benchmark, we attribute the fund's underperformance to our portfolio mix of
mortgage-backed and Treasury securities. During periods of falling interest
rates, Treasuries usually outperform mortgage-backed issues due to concerns
about refinancing. The fund's benchmark, the Merrill Lynch 5-10 Year Treasury
Index, is comprised entirely of Treasury securities.

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Neither safety of principal nor stability of
income is guaranteed. During most periods, the fund's advisor waived or paid
certain expenses and/or the fund's distributor voluntarily waived certain 12b-1
fees. Without waivers, returns would have been lower.

All fund and benchmark returns include reinvested distributions.

FIXED-INCOME INVESTMENTS BENEFITED FROM THE IMPACT OF THE ASIAN RECESSION.
Between October and early January, long-term bond yields declined by about 0.50%
as global investors sought refuge in high-quality U.S. fixed income securities
amid the economic storm raging in Asia. Domestic investors also bought
longer-term bonds, confident that reduced demand for U.S. goods abroad and the
impact of the strong dollar at home would keep inflation under control.
Better-than-expected inflation news and reduced borrowing requirements from the
federal government also helped to create a bullish environment for fixed income
securities. However, when U.S. economic growth appeared to remain strong during
the first quarter of 1998, bond yields rose modestly during the final weeks of
the reporting period.

DESPITE THE ROBUST DOMESTIC ECONOMY, INFLATION REMAINED BENIGN. Prices at the
consumer level increased just 1.4% during the 12 months through March, while
producer prices actually declined during the same period. Excluding the volatile
food and energy sectors,*** last year's 2.2% rise in the consumer price index
was the smallest in more than 30 years. Significant gains in productivity,
falling energy prices, and the strong dollar helped to keep inflation in check
despite strong economic growth and an increasingly tight labor market.

THE FEDERAL RESERVE MAINTAINED A STABLE MONETARY POLICY.  Faced with little
evidence of reported inflation and concerned about exacerbating the difficulties
in Asia, the Federal Reserve Board kept the target for the key Federal funds
lending rate*** at 5.5% during the reporting period. The decline in long-term
bond yields, coupled with steady short-term interest rates, resulted in a
significant flattening of the yield curve.***

Thank you for your investment in Government Income Fund. We continue our
dedication to providing you with quality investment management.

Sincerely,

conditions.

FIXED INCOME INVESTMENTS BENEFITED FROM THE IMPACT OF THE ASIAN RECESSION.
Between October and early January, yields declined across the maturity spectrum
as global investors sought refuge in high-quality U.S. bonds amid the economic
storm raging in Asia. Domestic investors also bought fixed income securities,
confident that reduced demand for U.S. goods abroad and the impact of the strong
dollar at home would keep inflation under control. Better-than-expected
inflation news and reduced borrowing requirements from the federal government
also helped to create a bullish environment for fixed income securities.

* PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Neither safety of principal nor stability of
income is guaranteed. During most periods, the fund's advisor waived or paid
certain expenses and/or the fund's distributor voluntarily waived certain 12b-1
fees. Without waivers, the class A returns would have been lower.

All fund and benchmark returns include reinvested distributions.

DURING THE SECOND HALF OF THE REPORTING PERIOD, BOND YIELDS BACKED UP AS
ECONOMIC GROWTH REMAINED STRONG. Investors had expected the effects of the Asian
crisis to begin slowing the domestic economy by early 1998. When subsequent
evidence showed continued strength in consumer demand, interest rates retraced a
portion of their earlier decline. Beginning in mid-January, the yield on the
Treasury's 30-year benchmark bond increased by about one-fourth of one
percentage point to close the reporting period at slightly less than 6%. Also
during this time, yield differentials between high- and low-rated bonds
contracted, after widening significantly during the fourth quarter of 1997.

DESPITE THE ROBUST DOMESTIC ECONOMY, INFLATION REMAINED BENIGN. Prices at the
consumer level increased just 1.4% during the 12 months through March, while
producer prices actually declined over the same period. Excluding the volatile
food and energy sectors,*** last year's 2.2% rise in the consumer price index
was the smallest in more than 30 years. Significant gains in productivity,
falling energy prices, and the strong dollar helped to keep inflation in check
despite strong economic growth and an increasingly tight labor market.

THE FEDERAL RESERVE MAINTAINED A STABLE MONETARY POLICY. Faced with little
evidence of reported inflation and concerned about exacerbating the difficulties
in Asia, the Federal Reserve Board kept the target for the key Federal funds
lending rate*** at 5.5 percent over the reporting period. The decline in
long-term bond yields, coupled with steady short-term interest rates, resulted
in a significant flattening of the yield curve.***

ADJUSTABLE RATE MORTGAGE SECURITIES FUND

DEAR SHAREHOLDERS:

FOR THE SIX MONTHS ENDED MARCH 31, 1998, ADJUSTABLE RATE MORTGAGE SECURITIES
FUND PRODUCED A TOTAL RETURN OF 2.75%.*  This return includes reinvested
distributions but does not include the fund's sales charge. While the Lehman
Brothers Adjustable Rate Mortgage Index,** the fund's unmanaged market
benchmark,*** returned 3.14%, the fund's performance was better than the average
fund in the Lipper Adjustable Rate Mortgage Funds Average,+ which returned 2.39%
during the same time frame. Our decision to avoid adjustable rate mortgage
securities that are sensitive to prepayment risk, along with placing a
significant proportion of our assets in fixed rate mortgage securities, worked
well for our investors.

OVERALL, SHORT-TERM INTEREST RATES ROSE SLIGHTLY DURING THE PAST SIX MONTHS,
ALTHOUGH THEY FELL RATHER DRAMATICALLY IN JANUARY WHEN FEARS ABOUT THE ASIAN
ECONOMIC CRISIS PEAKED. While the U.S. economy continued to produce impressive
growth, inflation remained low and wages rose only slightly. In fact, the Asian
economic crisis -- which devalued currencies, rattled the foundations of shaky
financial institutions and caused a sharp rise in bankruptcies -- may have put a
damper on U.S. inflation expectations. The main reason: U.S. corporations fear
Asian goods, made cheaper by the devaluation*** of their currencies, could
compel U.S. producers to hold down their prices in

response. Those competitive pressures, combined with sharply reduced Asian
demand for U.S. products, may slow U.S. economic growth, and relieve wage and
price pressures that seemed inevitable as U.S. unemployment reached 20-year
lows.

GIVEN OUR EXPECTATION THAT THE ECONOMY WOULD BE WEAKER LATER THIS YEAR, WE SOLD
PREPAYMENT-SENSITIVE ISSUES AND BOUGHT SECURITIES WITH STABLE INCOME STREAMS.
Although the softer economy might point to lower interest rates over the long
haul, we are not prepared to sacrifice income in order to boost our price
sensitivity (or the potential for big price gains if interest rates fall). This
strategy of selling prepayment-sensitive issues has largely been in place since
mid-1996, and the portfolio, consequently, has had very little turnover in the
time since we last wrote. Overall, our goal is to achieve the highest current
income that is consistent with stable principal.

WE SOLD OUR HIGH-COUPON ARMS, WHICH TEND TO PREPAY QUICKLY WHEN INTEREST RATES
FALL. To maintain a consistent dividend for our shareholders, we reinvested that
money in floating rate securities pegged to a lagging index such as the 11th
Federal Reserve District's Cost of Funds Index, commonly called COFI. Since that
index is an average, which tends to adjust more slowly than market rates, we
hope to maintain our income, should interest rates fall. We also continue to
hold 20% of our total assets in fixed-rate mortgage securities. By holding
fixed-rate mortgages we can take advantage of price gains when interest rates
fall, and their yields are stable. This helps us maintain a consistent dividend
payout.

ADJUSTABLE RATE MORTGAGE SECURITIES FUND  (CONTINUED)
- --------------------------------------------------------------------------------


LOOKING AHEAD, OUR OUTLOOK CALLS FOR STABLE INTEREST RATES AS WE BELIEVE
ECONOMIC GROWTH WILL SLOW LATER THIS YEAR. In effect, some of the surprisingly
strong economic activity we saw in the first quarter of 1998 was probably
"borrowed" from the second quarter: the combination of unseasonably warm weather
in much of the U.S. and early tax refund payments boosted items like housing
starts and consumer sales. But we expect that growing consumer debt is likely to
put a damper on spending later this year and economic growth will slow. In this
environment, we plan to maintain our current focus on stable income.

Thank you for investing in Adjustable Rate Mortgage Securities Fund.

Sincerely,




/s/ Tom McGlinch              /s/ Wan-Chong Kung

 ................................
                      Piper Funds Inc. (Piper Funds) and Piper Funds Inc.-II
                      (Piper Funds II) are each registered under the Investment
                      Company Act of 1940 (as amended) as single, open-end
                      management investment companies. Piper Funds currently has
                      12 series, including Government Income Fund and
                      Intermediate Bond Fund. Each fund is classified as a
                      diversified series. Piper Funds II currently has one
                      series, Adjustable Rate Mortgage Securities Fund, which is
                      classified as a diversified series.
 
                      On September 1, 1995, four closed-end funds, American
                      Adjustable Rate Term Trust 1996 (BDJ), American Adjustable
                      Rate Term Trust 1997 (CDJ), American Adjustable Rate Term
                      Trust 1998 (DDJ) and American Adjustable Rate Term Trust
                      1999 (EDJ) merged into Adjustable Rate Mortgage Securities
                      Fund. (DDJ) is considered the surviving entity for
                      financial reporting purposes.
 
                      The articles of incorporation of Piper Funds and Piper
                      Funds II permit the boards of directors to create
                      additional series in the future.
 
                      Intermediate Bond Fund commenced offering Class Y 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:
                      - Subject to a front-end sales charge
 
                      - Subject to distribution and service fees
 
                      CLASS Y:
                      - Requires a minimum initial investment of $1 million
 
                      - No front-end or contingent deferred sales charges
 
                      - No distribution and service fees
 
                      The classes of shares of Intermediate Bond Fund have the
                      same rights and are identical in all respects except that
                      each class bears different distribution expenses, has
                      exclusive voting rights with respect to matters affecting
                      that class and has different exchange privileges.
                      Government Income Fund and Adjustable Rate Mortgage
                      Securities Fund each have a single class of shares, which
                      are shown as Class A in the financial statements.
 
                      Government Income Fund invests primarily in securities
                      issued or guaranteed as to payment of principal and
                      interest by the U.S. government, its agencies or
                      instrumentalities, including mortgage-backed securities.

                      of investment-quality debt securities.

                      in adjustable rate mortgage securities.

                      INVESTMENTS IN SECURITIES
                      Portfolio securities for which market quotations are
                      readily available are valued at current market value. If
                      market quotations or valuations are not readily available,
                      or if such quotations or valuations are believed to be

                      valued according to procedures adopted by the funds' board
                      of directors in good faith at "fair value", that is, a
                      price that the fund might reasonably expect to receive for
                      the security or other asset upon its current sale.
 
                      The current market value of certain fixed income
                      securities is provided by an independent pricing service.
                      Fixed income securities for which prices are not available
                      from an independent pricing service but where an active
                      market exists are valued using market quotations obtained
                      from one or more dealers that make markets in the
                      securities or from a widely-used quotation system.
                      Short-term securities with maturities of 60 days or less
                      are valued at amortized cost, which approximates market
                      value.
 
                      Securities transactions are accounted for on the date
                      securities are purchased or sold. Realized gains and
                      losses are calculated on the identified-cost basis.
                      Interest income, including amortization of bond discount
                      and premium, is recorded on an accrual basis.
 
                      FUTURES TRANSACTIONS
                      In order to gain exposure to or protect from changes in
                      the market, Government Income Fund and Adjustable Rate
                      Mortgage Securities Fund may buy and sell financial
                      futures contracts and related options. Risks of entering
                      into futures contracts and related options include the
                      possibility that there may be an illiquid market and that
                      a change in the value of the contract or option may not
                      correlate with changes in the value of the underlying
                      securities.
 
                      Upon entering into a futures contract, the funds are
                      required to deposit either cash or securities in an amount
                      (initial margin) equal to a certain percentage of the
                      contract value. Subsequent payments (variation margin) are
                      made or received by the funds each day. The variation
                      margin payments are equal to the daily changes in the
                      contract value and are recorded as unrealized gains and
                      losses. The funds recognize a realized gain or loss when
                      the contract is closed or expires.
 
                      SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
                      Delivery and payment for securities that have been
                      purchased by the funds on a when-issued or
                      forward-commitment basis can take place a month or more
                      after the transaction date. During this period, such
                      securities do not earn interest, are subject to market
                      fluctuation and may increase or decrease in value prior to
                      their delivery. The funds segregate, with their custodian,
                      assets with a market value equal to the amount of their
                      purchase commitments. The purchase of securities on a
                      when-issued or forward-commitment basis may increase the
                      volatility of the funds' net asset value if the funds make
                      such purchases while remaining substantially fully
                      invested. As of March 31, 1998, Government Income Fund had
                      entered into outstanding when-issued or forward
                      commitments of $9,996,094.
 
                      In connection with their ability to purchase securities on
                      a when-issued or forward-commitment basis, Government
                      Income Fund and Intermeditate Bond Fund may enter into
                      mortgage dollar rolls in which the funds sell securities
                      purchased on a forward commitment basis and simultaneously
                      contract with a counterparty to repurchase similar (same
                      type, coupon and maturity) but not identical

                      securities on a specified future date. As an inducement to
                      "roll over" their purchase commitments, the funds receive
                      negotiated fees. For the six months ended March 31, 1998,
                      such fees earned amounted to $46,996 for Government Income
                      Fund.
 
                      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.
 
                      Net investment income and net realized gains (losses) may
                      differ for financial statement and tax purposes primarily
                      because of losses deferred due to "wash sale" transactions
                      and the timing of recognition of income on certain
                      collateralized mortgage-backed securities. The character
                      of distributions made during the year from net investment
                      income or net realized gains may differ from its ultimate
                      characterization for federal income tax purposes. In
                      addition, due to the timing of dividend distributions, the
                      fiscal year in which amounts are distributed may differ
                      from the year that the income or realized gains or losses
                      were recorded by the funds.
 
                      ALLOCATION OF INCOME, EXPENSES AND GAINS AND LOSSES
                      Income, expenses (other than class-specific expenses) and
                      realized and unrealized gains and losses for Intermediate
                      Bond 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.
 
                      DISTRIBUTIONS TO SHAREHOLDERS
                      Distributions to shareholders from net investment income
                      for Government Income Fund and Adjustable Rate Mortgage
                      Securities Fund are declared daily and paid monthly.
                      Distributions to shareholders from net investment income
                      for Intermediate Bond Fund are declared separately for
                      each class daily and paid monthly. Net realized gains
                      distributions for the funds, if any, will be made at least
                      annually. Distributions are payable in cash or reinvested
                      in additional shares of the same class.
 
                      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 to a joint 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.
                      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.

                      USE OF ESTIMATES
                      The preparation of financial statements in conformity with
                      generally accepted accounting principles requires
                      management to make estimates and assumptions that affect
                      the reported amounts in the financial statements. Actual
                      results could differ from these estimates.

(5) EXPENSES
 ................................
                      INVESTMENT MANAGEMENT FEE
                      Piper Funds and Piper Funds II have entered into
                      investment management agreements with Piper Capital
                      Management Incorporated (Piper Capital) under which Piper
                      Capital manages each fund's assets and furnishes related
                      office facilities, equipment, research and personnel. The
                      agreements require each fund to pay Piper Capital a
                      monthly fee based on average daily net assets. The fees
                      for each fund are as follows: Government Income Fund, an
                      annual rate of 0.50% of the first $250 million in net
                      assets and decreasing percentages thereafter to 0.40% of
                      net assets in excess of $500 million; Intermediate Bond
                      Fund, an annual rate of 0.30% of the first $100 million in
                      net assets, 0.25% of the next $150 million and 0.20% of
                      net assets in excess of $250 million; Adjustable Rate
                      Mortgage Securities Fund, an annual rate of 0.35% on the
                      first $500 million in net assets and 0.30% of net assets
                      in excess of $500 million. For the six months ended March
                      31, 1998, the effective management fee paid by the funds
                      was 0.50%, 0.30% and 0.35% on an annual basis for
                      Government Income Fund, Intermediate Bond Fund and
                      Adjustable Rate Mortgage Securities Fund, respectively.
 
                      DISTRIBUTION AND SERVICE FEES
                      Each fund also pays Piper Jaffray fees accrued daily and
                      paid quarterly for providing shareholder services and
                      distribution-related services. The fees for each fund,
                      which are being voluntarily limited for Government Income
                      Fund and Class A of Intermediate Bond Fund for the year
                      ending September 30, 1998, are stated below as a percent
                      of average daily net assets attributable to such shares.

                      fees; registration fees; printing and shareholder reports;
                      transfer agent fees and expenses; legal, auditing and

(6) CAPITAL LOSS
    CARRYOVER
 ................................
                      For federal income tax purposes, the following funds had
                      capital loss carryovers at September 30, 1997, which, if
                      not offset by subsequent capital gains, will expire on the
                      funds' fiscal year-ends as indicated below. It is unlikely
                      the board of directors will authorize a distribution of
                      any net realized capital gains until the available capital
                      loss carryovers have been offset or expire.

(7) PENDING
    ACQUISITION
 ................................
                      On December 15, 1997, Piper Jaffray Companies Inc., the
                      parent company of the funds' investment advisor, announced
                      that it had entered into an agreement to be acquired by
                      U.S. Bancorp. It is

                      anticipated that this acquisition will be completed in the
                      second quarter of 1998, subject to regulatory approval,
                      the approval of Piper Jaffray Companies shareholders and
                      the satisfaction of customary closing conditions.
 
                      U.S. Bancorp is a multi-state bank holding company
                      headquartered in Minneapolis, Minnesota with a geographic
                      service area spanning 17 states. As of December 31, 1997,
                      U.S. Bancorp was the 15th largest U.S. commercial bank
                      holding company, with assets of nearly $71.3 billion. U.S.
                      Bank National Association ("U.S. Bank"), a wholly owned
                      subsidiary of U.S. Bancorp, currently acts as the
                      investment advisor to 32 mutual funds (the "First American
                      Funds"). As of December 31, 1997, U.S. Bank, acting
                      through its First American Asset Management group, managed
                      more than $55 billion in assets, including approximately
                      $20.5 billion in assets of the First American Funds.
 
                      Effective as of the date of the acquisition, SEI
                      Investments Distribution Company will assume the role of
                      the principal distributor for the funds.
 
                      Under the Investment Company Act of 1940, as amended (the
                      "1940 Act"), consummation of the acquisition of Piper
                      Jaffray Companies by U.S. Bancorp will result in the
                      assignment and automatic termination of the funds'
                      investment advisory agreements with Piper Capital
                      Management Incorporated. The 1940 Act requires that any
                      new investment advisory agreements for the funds be
                      approved by the funds' board of directors and
                      shareholders.
 
(8) SUBSEQUENT EVENT
 ................................
                      FUND CONVERSION
                      In connection with the acquisition of Piper Jaffray
                      Companies Inc. by U.S. Bancorp, the funds' board of
                      directors has recommended that the funds be merged into
                      mutual funds managed by First American Asset Management, a
                      division of U.S. Bank. The proposed fund mergers require
                      shareholder approval and proxy statements requesting
                      shareholder votes will be mailed in May 1998. If approved,
                      the mergers are expected to occur on or about July 31,
                      1998.

           TO MATURITY. INTEREST RATES DISCLOSED REPRESENT CURRENT YIELDS BASED
           UPON THE CURRENT COST BASIS AND ESTIMATED TIMING AND AMOUNT OF FUTURE
           CASH FLOWS.

           THEIR INITIAL ACCRUAL PERIODS, BUT ACCRUE ADDITIONAL PRINCIPAL AT
           SPECIFIED RATES. INTEREST RATE DISCLOSED REPRESENTS CURRENT YIELD

SALES CHARGE. This compared to a 3.89% total return for the fund's benchmark,
the Lehman Brothers Municipal Bond Index,** and a 3.73% return for the Lipper
General Municipal Bond Funds Average.+

FIXED INCOME INVESTMENTS BENEFITED FROM THE IMPACT OF THE ASIAN RECESSION.
Between mid-October and early-January, long-term Treasury bond yields declined
by about 0.75% as global investors sought refuge in U.S. government securities
amid the economic turmoil in Asia. Domestic investors also bought longer-term
bonds, confident that reduced demand for U.S. goods abroad and the impact of the
strong dollar at home would continue to keep inflation under control. Reduced
borrowing requirements from the federal government also contributed to a bullish
environment for fixed income securities.

TAX-EXEMPT BONDS GAINED FROM THE GLOBAL 'FLIGHT TO QUALITY.' While municipal
issues did not benefit directly from the foreign demand for government bonds
that accompanied the drop in Treasury yields, all fixed income securities
compete for funds on an after-tax basis among domestic investors. Consequently,
yields on long-term municipal bonds also drifted lower in concert with Treasury
issues over the first three months of the reporting period.

YIELDS ACROSS THE FIXED INCOME SPECTRUM REBOUNDED BEGINNING IN MID-JANUARY.
Investors had expected fallout from the Asian recessions to begin slowing the
U.S. economy by the end of the first quarter. When little evidence appeared of
an imminent deceleration in the rate of domestic economic growth, bond yields
began climbing, retracing about one-third of the previous decline. Overall, the
yield on the Bond Buyer 20-Bond Index (a municipal benchmark comprised of
AA-rated general obligation bonds) dropped by 0.15% over the six-month reporting
period.

DESPITE THE STRONG ECONOMY, INFLATION REMAINED BENIGN. At the consumer level,
prices rose just 1.4% during the 12 months through March, while the producer
price index actually fell during the same period. Significant gains in
productivity, falling energy prices, and the strong U.S. dollar helped to keep
inflation in check despite a robust economy and an increasingly tight labor
market. Faced with little evidence of inflation and concerned about exacerbating
the difficulties in Asia, Federal Reserve policy makers kept short-term interest
rates steady during the reporting period.

THE FUND MAINTAINED ITS POLICY OF EMPHASIZING CREDIT QUALITY. In recent years,
yield differentials between similar-maturity bonds of differing credit quality
have narrowed significantly. At current levels, we believe that the marginal
improvement in yields offered by lower-rated debt does not provide adequate
compensation to take on the incremental credit risk. Accordingly, 67% of the
fund's assets are invested in bonds rated AA or higher or short-term rating
equivalent. While 21% of the fund's portfolio remains in non-rated paper, these
bonds were acquired at a time when quality spreads were significantly wider,
thus cushioning the potential impact of any additional credit risk.

NATIONAL TAX-EXEMPT FUND  (CONTINUED)
- --------------------------------------------------------------------------------


MUNICIPAL BOND YIELDS ARE ATTRACTIVE RELATIVE TO THOSE AVAILABLE ON TAXABLE
ISSUES. Bolstered by strong economic growth and bulging tax coffers of municipal
issuers, credit upgrades by the rating agencies have continued to substantially
outpace downgrades. As interest rates dropped during the fourth quarter of last
year, municipalities rushed to finance new projects and refund higher-yielding
issues. The sharp increase in supply caused a mild underperformance by municipal
bonds relative to Treasuries, especially during the last three months of 1997.
As a result of that underperformance, however, long-term AAA-rated tax-exempt
yields have risen to roughly 87% of comparable-maturity Treasury issues, an
attractive differential by historical standards. At current levels, municipal
bond yields provide a significant after-tax premium for individuals in the 28%
federal income tax bracket and above.

Thank you for your investment in NationalTax-Exempt Fund. We appreciate the
opportunity to help you achieve your investment goals.

Sincerely,


/s/ Ronald Reuss                        /s/ Douglas White

DEAR SHAREHOLDERS:

MINNESOTA TAX-EXEMPT FUND PROVIDED A TOTAL RETURN OF 3.78%* FOR THE SIX MONTHS
ENDED MARCH 31, 1998, WHICH REFLECTS REINVESTED DISTRIBUTIONS BUT NOT THE FUND'S
SALES CHARGE. This compared to a 3.89% total return for the fund's benchmark,
the Lehman Brothers Municipal Bond Index,** and a 3.46% return for the Lipper
Minnesota Municipal Bond Funds Average.+

FIXED INCOME INVESTMENTS BENEFITED FROM THE IMPACT OF THE ASIAN RECESSION.
Between mid-October and early-January, long-term Treasury bond yields declined
by about 0.75% as global investors sought refuge in U.S. government securities
amid the economic turmoil in Asia. Domestic investors also bought longer-term
bonds, confident that reduced demand for U.S. goods abroad and the impact of the
strong dollar at home would continue to keep inflation under control. Reduced
borrowing requirements from the federal government also contributed to a bullish
environment for fixed income securities.

TAX-EXEMPT BONDS GAINED FROM THE GLOBAL 'FLIGHT TO QUALITY.' While municipal
issues did not benefit directly from the foreign demand for government bonds
that accompanied the drop in Treasury yields, all fixed income securities
compete for funds on an after-tax basis among domestic investors. Consequently,
yields on long-term municipal bonds also drifted lower in concert with Treasury
issues over the first three months of the reporting period.

 * PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. PAST PERFORMANCE
DOES NOT GUARANTEE FUTURE RESULTS. The investment return and principal value of
an investment will fluctuate so that fund shares, when sold, may be worth more
or less than their original cost. Neither safety of principal nor stability of
income is guaranteed.  During most periods, the fund's advisor waived or paid
certain expenses and/or the fund's distributor voluntarily limited certain 12b-1

YIELDS ACROSS THE FIXED INCOME SPECTRUM REBOUNDED BEGINNING IN MID-JANUARY.
Investors had expected fallout from the Asian recessions to begin slowing the
U.S. economy by the end of the first quarter. When little evidence appeared of
an imminent deceleration in the rate of domestic economic growth, bond yields
began climbing, retracing about one-third of the previous decline. Overall, the
yield on the Bond Buyer 20-Bond Index (a municipal benchmark comprised of
AA-rated general obligation bonds) dropped by 0.15% over the six-month reporting
period.

DESPITE THE STRONG ECONOMY, INFLATION REMAINED BENIGN. At the consumer level,
prices rose just 1.4% during the 12 months through March, while the producer
price index actually fell during the same period. Significant gains in
productivity, falling energy prices, and the strong U.S. dollar helped to keep
inflation in check despite a robust economy and an increasingly tight labor
market. Faced with little evidence of inflation and concerned about exacerbating
the difficulties in Asia, Federal Reserve policy makers kept short-term interest
rates steady over the reporting period.

THE FUND MAINTAINED ITS POLICY OF EMPHASIZING CREDIT QUALITY. In recent years,
yield differentials between similar-maturity bonds of differing credit quality
have narrowed significantly. At current levels, we believe that the marginal
improvement in yields offered by lower-rated debt does not provide adequate
compensation to take on the incremental credit risk. Accordingly, 63% of the
fund's assets are invested in bonds rated AA or higher or short-term rating
equivalent. While 23% of the fund's portfolio remains in non-rated paper, these
bonds were acquired at a time when quality spreads were significantly wider,
thus cushioning the potential impact of any additional credit risk. The fund
will continue to search for issues that offer the combination of compelling
value and the potential for significant improvement in underlying fundamentals.

MINNESOTA TAX-EXEMPT FUND  (CONTINUED)
- --------------------------------------------------------------------------------

FALLING INTEREST RATES CAUSED A BULGE IN SUPPLY. Municipalities in Minnesota
rushed to finance new projects and refund higher-yielding issues as interest
rates dropped during the reporting period. Aggregate new issues and refinancing
in the state increased at nearly double the national rate during the first
quarter of 1998, offsetting a slight decline in supply last year. The fund is
seeking opportunities to take advantage of the higher supply of Minnesota bonds
to increase the portfolio's book yield and call protection.

MUNICIPAL BOND YIELDS ARE ATTRACTIVE RELATIVE TO THOSE AVAILABLE ON TAXABLE
ISSUES. Bolstered by strong economic growth and bulging tax coffers of municipal
issuers, credit upgrades by the rating agencies have continued to substantially
outpace downgrades. The sharp increase in supply caused a mild underperformance
by municipal bonds relative to Treasuries, especially during the last three
months of 1997. As a result of that underperformance, however, long-term
AAA-rated tax-exempt yields have risen to roughly 87% of comparable-maturity
Treasury issues, an attractive differential by historical standards. At current
levels, municipal bond yields provide a significant after-tax premium for
individuals in the 28% federal income tax bracket and above.

Thank you for your investment in Minnesota Tax-Exempt Fund. We appreciate the
opportunity to help you achieve your investment goals.

Sincerely,



/s/ Ronald Reuss                   /s/ Douglas White

(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 National Tax-Exempt
                      Fund, a diversified series, and Minnesota Tax-Exempt Fund,
                      a non-diversified series (the funds). The company's
                      articles of incorporation permit the board of directors to
                      create additional series in the future.
 
                      Minnesota Tax-Exempt Fund commenced offering Class Y
                      shares on July 1, 1997. All shares existing prior to that
                      date were classified as Class A shares. Key features of
                      each class are:
 
                      CLASS A:
                      - Subject to a front-end sales charge
 
                      - Subject to distribution and service fees
 
                      CLASS Y:
                      - Requires a minimum initial investment of $1 million
 
                      - No front-end or contingent deferred sales charges
 
                      - No distribution and service fees
 
                      The classes of shares of Minnesota Tax-Exempt Fund have
                      the same rights and are identical in all respects except
                      that each class bears different distribution expenses, has
                      exclusive voting rights with respect to matters affecting
                      that class and has different exchange privileges. National
                      Tax-Exempt Fund has a single class of shares, which is
                      shown as Class A in the financial statements.
 
                      National Tax-Exempt Fund invests primarily in
                      investment-grade or comparable quality municipal bonds,
                      notes and tax-free municipal leases issued by states,
                      territories and possessions of the United States, the
                      District of Columbia or their agencies, instrumentalities
                      and political subdivisions. These may include municipal
                      derivative securities.

                      subdivisions, and certain securities of U.S. territorial
                      possessions. These may include municipal derivative

    ACCOUNTING
    POLICIES
 ................................
                      INVESTMENTS IN SECURITIES
                      Portfolio securities for which market quotations are
                      readily available are valued at current market value. If
                      market quotations or valuations are not readily available,
                      or if such quotations or valuations are believed to be
                      inaccurate, unreliable or not reflective of market value,
                      portfolio securities are valued according to procedures
                      adopted by the funds' board of directors in good faith at
                      "fair value", that is, a price that the fund might
                      reasonably expect to receive for the security or other
                      asset upon its current sale.

                      The current market value of certain fixed income
                      securities is provided by an independent pricing service.
                      Fixed income securities for which prices are not available
                      from an independent pricing service but where an active
                      market exists are valued using market quotations obtained
                      from one or more dealers that make markets in the
                      securities or from a widely-used quotation system.
                      Short-term securities with maturities of 60 days or less
                      are valued at amortized cost, which approximates market
                      value.
 
                      Securities transactions are accounted for on the date
                      securities are purchased or sold. Realized gains and
                      losses are calculated on the identified-cost basis.
 
                      SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
                      Delivery and payment for securities that have been
                      purchased by the funds on a when-issued or
                      forward-commitment basis can take place a month or more
                      after the transaction date. During this period, such
                      securities do not earn interest, are subject to market
                      fluctuation and may increase or decrease in value prior to
                      their delivery. The funds segregate, with their custodian,
                      assets with a market value equal to the amount of their
                      purchase commitments. The purchase of securities on a
                      when-issued or forward-commitment basis may increase the
                      volatility of the funds' net asset value if the funds make
                      such purchases while remaining substantially fully
                      invested. As of March 31, 1998, Minnesota Tax-Exempt had
                      entered into outstanding when-issued or forward
                      commitments of $498,615.
 
                      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.
 
                      Net investment income and net realized gains (losses) may
                      differ for financial statement and tax purposes primarily
                      because of market discount amortization. The character of
                      distributions made during the year from net investment
                      income or net realized gains may differ from its ultimate
                      characterization for federal income tax purposes. In
                      addition, due to the timing of dividend distributions, the
                      fiscal year in which amounts are distributed may differ
                      from the year that the income or realized gains or losses
                      were recorded by the funds.
 
                      ALLOCATION OF INCOME, EXPENSES AND GAINS AND LOSSES
                      Income, expenses (other than class-specific expenses) and
                      realized and unrealized gains and losses for Minnesota
                      Tax-Exempt 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.
 
                      DISTRIBUTIONS TO SHAREHOLDERS
                      Distributions from net investment income for National
                      Tax-Exempt Fund are declared daily and paid monthly.
                      Distributions to shareholders from net investment income
                      for Minnesota Tax-Exempt are

- --------------------------------------------------------------------------------
                      declared separately for each class daily and paid monthly.
                      Net realized gains distributions, if any, will be made at
                      least annually. Distributions are payable in cash or
                      reinvested in additional shares of the same class.
 
                      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 to a joint 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.
                      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.
 
                      USE OF ESTIMATES
                      The preparation of financial statements in conformity with
                      generally accepted accounting principles requires
                      management to make estimates and assumptions that affect
                      the reported amounts in the financial statements. Actual
                      results could differ from these estimates.

    ACQUISITION
 ................................
                      On December 15, 1997, Piper Jaffray Companies Inc., the
                      parent company of the funds' investment advisor, announced
                      that it had entered into an agreement to be acquired by
                      U.S. Bancorp. It is anticipated that this acquisition will
                      be completed in the second quarter of 1998, subject to
                      regulatory approval, the approval of Piper Jaffray
                      Companies shareholders and the satisfaction of customary
                      closing conditions.
 
                      U.S. Bancorp is a multi-state bank holding company
                      headquartered in Minneapolis, Minnesota with a geographic
                      service area spanning 17 states. As of December 31, 1997,
                      U.S. Bancorp was the 15th largest U.S. commercial bank
                      holding company, with assets of nearly $71.3 billion. U.S.
                      Bank National Association ("U.S. Bank"), a wholly owned
                      subsidiary of U.S. Bancorp, currently acts as the
                      investment advisor to 32 mutual funds (the "First American

                      through its First American Asset Management group, managed

                      $20.5 billion in assets of the First American Funds.
 
                      Effective as of the date of the acquisition, SEI
                      Investments Distribution Company will assume the role of
                      the principal distributor for the funds.
 
                      Under the Investment Company Act of 1940, as amended (the
                      "1940 Act"), consummation of the acquisition of Piper
                      Jaffray Companies by U.S. Bancorp will result in the

Glossary of Terms ***
- --------------------------------------------------------------------------------

BENCHMARK 
A benchmark is an established basis of comparison for an 
investment's performance. A benchmark may be an unmanaged market index or a 
group of similar investments.

DEVALUED OR DEVALUATION
The lowering of the value of a country's currency relative to gold and/or the
currencies of other nations. Devaluation can also result from a rise in value of
other currencies relative to the currency of a particular country.

EFFECTIVE DURATION
Effective duration estimates how much the value of a security is expected to
change with a given change in interest rates. Longer effective durations
indicate more sensitivity to changes in interest rates. For example, if interest
rates were to increase by 1%, the market value of a bond with an effective
duration of five years would decrease by about 5%, with all other factors being
constant.  It is important to remember that effective duration is based on
certain assumptions and has several limitations.  It is most effective as a
measure when interest rate changes are small, rapid and occur equally across all
the different points of the yield curve.  In addition, effective duration is
difficult to calculate precisely for bonds with prepayment options, such as
mortgage-backed securities.

If a fund has an aggressive effective duration, it means its managers have set a
longer duration posture in comparison to the fund's benchmark.  A fund with a
long effective duration is more sensitive to changing interest rates.

If a fund has a defensive effective duration, it means its managers have set a
shorter duration posture in comparison to the fund's benchmark, to make the fund
less sensitive to changing interest rates.

If a fund has a neutral effective duration, the duration is approximately the
same as its benchmark.

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.  The federal funds rate is the most sensitive 
indicator of the direction of interest rates, since it is set daily by the 
market, unlike the prime rate and the discount rate, which are periodically 
changed by banks and by the Federal Reserve Board, respectively.

OVERWEIGHTED OR OVERWEIGHTING
In portfolio management, overweighting means a fund's portfolio contains a
higher percentage of a certain sector than its benchmark.

SECTOR
Refers to a particular group of stocks, usually in one industry.

UNDERWEIGHTED OR UNDERWEIGHTING
In portfolio management, underweighting means a fund's portfolio contains a
lower percentage of a certain sector than its benchmark.

VALUATIONS
The determined or estimated value of a particular stock.

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.
