Report From Your Investment Advisor
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
We are pleased to present this semiannual report for The One Group(R) Family of
Mutual Funds. On the following pages, you will find an overview of the financial
markets and your fund's performance for the period from July 1, 1997, through
December 31, 1997.
 
DEAR VALUED SHAREHOLDER:
Thank you for continuing to support The One Group Family of Mutual Funds during
an interesting, challenging and ultimately rewarding year for investors.
 
Despite strong volatility throughout 1997 and turmoil in Asia, the Dow Jones
Industrial Average was up 24.94% for 1997. Never before had the index returned
more than 20% for three consecutive years. The S&P 500 Index soared even higher,
closing the year up 33.36%.
 
At the same time, and largely the result of low inflation, a strong U.S. dollar
and the flight to quality spurred by the Asian crisis, U.S. bond yields ended
the year on an impressive note. The 30-year Treasury, for example, ended the
year yielding 5.92%, close to its 20-year low. (As bond yields fall, bond prices
go up.)
 
ONCE AGAIN, A PHILOSOPHY REINFORCED
While the calendar-year returns for both the stock and bond markets are
impressive, events in the final six months of 1997 may be the most memorable. On
August 6, the Dow closed at 8,259, a record high and its peak for the calendar
year. Shortly thereafter, though, volatility rocked the market, as the effects
of the Asian financial crisis worked their way west. These forces culminated on
Monday, October 27, when the Dow plummeted more than 554 points, its
largest-ever point decline.
 
This drop may be the defining moment for 1997's financial markets, and it
presented a significant challenge for investors. But, rather than panicking,
shareholders of The One Group demonstrated a clear understanding of market
dynamics and the importance of maintaining a long-term investment philosophy.
 
I am pleased to report that there were no significant redemptions of One Group
shares after "Black Monday." To us, this implies that our investors understand
the potential dangers of selling their investments based on short-term
volatility. In fact, The One Group experienced a record purchase day on Tuesday,
October 28, indicating that investors realize the benefits of staying focused on
the stock market's long-term potential.
 
TAX BILL CHANGES FACE OF INVESTING
The second half of 1997 may be remembered as much for the jubilance it brought
investors as for the turmoil. The Taxpayer Relief Act of 1997 became law,
ushering in lower capital gains taxes for investors and new investment
opportunities poised to change the face of investing for years to come.
 
The cut in the capital gains tax rate may make investing in stocks even more
attractive for many investors. As you are planning for your future financial
needs and taking into consideration your appropriate asset allocation, please do
not overlook the impact of the new tax treatment of capital gains.
 
And, while you're planning for your financial future, take note that the 1997
tax law makes investing in IRAs even more attractive, particularly with the
introduction of the Roth IRA, a new type of account that offers tax-exempt
distributions in retirement. In addition, the Traditional IRA has been enhanced
with many new features.
 
The One Group can help you incorporate any of these retirement accounts into
your investment plan. Speak to your investment representative or call
1-800-480-4111 for more information on IRAs.
 
SEEK ADVICE FOR A YEAR'S WORTH OF EVENTS
With 1997's record volatility and the new investment opportunities introduced by
the tax law, now may be an ideal time to meet with your investment professional
and make sure your investment plan remains on track to meet your financial
needs.
 
As you probably know, your asset allocation--or the way your investment dollars
are strategically distributed among stock, bond and cash investments according
to your goals, risk tolerance and investing time frame--may be the
single-greatest determinant of your long-term investment success. After a year
full of market ups and downs, your asset allocation probably shifted. For
example, stock market appreciation may have caused your allocation to equities
to swing higher than called for in your plan. Your investment professional can
help you evaluate your plan and, if necessary, get it back on track.

Furthermore, your investment representative can help you make the most of the
Taxpayer Relief Act of 1997. Many of the provisions take effect with the 1998
tax year, so make sure you start off the year with the strategy that's most
appropriate for you.
 
Thank you for investing with The One Group Family of Mutual Funds and for your
ongoing support of the firm's time-tested investment philosophies. We look
forward to helping you achieve your financial goals in 1998 and beyond.
 
Sincerely,

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
ECONOMIC GROWTH REMAINS STRONG
Despite showing a slight slowdown from the first half of the year, U.S. economic
growth during the second half of 1997 remained robust at a growth rate of 3.7%.
For the entire 12-month period, the U.S. economy grew by a 3.8% growth rate.
 
Firm employment gains and strong consumer confidence fueled the growth rate. The
unemployment rate headed steadily downward, ending the year at 4.7%. The economy
witnessed an average of 301,500 new non-farm jobs being created per month, when
all that is needed to absorb the growth in the labor force and keep the
unemployment rate steady is 150,000.
 
LONG-TERM INTEREST RATES DECLINE
Slightly higher inflation in 1996 kept long-term interest rates relatively high
throughout much of 1997. With prices climbing 3.3% on a year-over-year basis in
1996, investors feared that inflation would keep that pace or even climb higher
in 1997.
 
But, as the year unfolded it became apparent that inflation was, indeed, under
control. For the final six months of the year the inflation rate was 2.0%, and
for the entire year prices were up only 1.7%, the best performance in 11 years.
 
Low prices helped pave the way for a significant decline in long-term interest
rates by the end of the year. Also significant was the impact of the Asian
financial crisis, which caused currency values to plunge and sent financial
markets into turmoil. As worldwide events unfolded during the second half of the
year, it became clear that the Asian economies would weaken. This caused
investors throughout the world to turn to the safety of U.S. Treasury
securities, which helped drive up prices.
 
As a result of these events, long-term interest rates showed a significant
decline during the second half of 1997--a decline that was much greater than the
economic fundamentals supported. At the end of the year, the yield on the
30-year U.S. Treasury bond was 5.92%, after starting the year at 6.64% and
climbing to a high of 7.17% in early April.
 
FED REMAINS IDLE
The Federal Reserve remained on the sidelines during the second half of the
year, after raising interest rates just once in all of 1997--a 0.25% increase of
the federal funds rate in March. This lack of monetary policy action kept
short-term interest rates relatively steady for the remainder of the year.
 
The impact of the Asian currency crisis and market meltdowns may have
contributed to the Fed's decision to keep rates unchanged in the second half of
1997. While strong economic growth certainly created a valid reason for another
rate hike, the Fed resisted the temptation, figuring that the Asian situation
would contribute to slower growth ahead.
 
LOOKING AHEAD
In terms of U.S. economic growth, the Asian crisis remains a factor that can't
be ignored. Thirty percent of U.S. exports go to Asia, and with many Asian
countries facing currency devaluations of 35% to 80%, consumers in that region
have significantly less purchasing power. Furthermore, there's the possibility
that this currency crisis could spread to Latin America, where another 20% of
U.S. exports are at risk if there are some currency devaluations.
 
The United States accounts for 28% of the non-Asian global economy, and,
therefore, should be heavily influenced by the change in trade flows from Asia.
Asian stock markets have dropped nearly 70% over the last several months, which
undoubtedly will be reflected in lower overall consumption, particularly for
foreign imports. And, as prices on goods produced in Asia continue to fall, U.S.
imports from that region should go up.
 
As a result, cheaper goods coming from Asia, and possibly Latin America, should
force domestic competitors to lower their prices (or face sharply lower sales
prospects). This could push the U.S. inflation rate to as low as 1.5% in 1998,
compared to 1.7% in 1997 and 3.3% in 1996. At the same time, fewer U.S. exports
and greater imports should cause economic growth to slow to a 2% year-over-year
average for 1998.

THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
Given all the instability overseas and the impending effects of a slowdown in
the U.S. economy, we believe that the Federal Reserve will lower interest rates
in 1998, probably sometime in the second half of the year. Long-term interest
rates should continue their downward trend, due to lower inflation and lower
economic growth. By the end of the year, we may see the yield on the 30-year
Treasury bond somewhere between 5.5% and 5.75%.

THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
AS VOLATILITY HEATS UP, INTEREST RATES DECLINE
Volatility initiated by financial and market distress in Asia was the key factor
at work in the bond market during the second half of 1997. As Asian currencies
fell, the credit quality of Yankee bonds (securities that represent
dollar-denominated, foreign-issued debt) deteriorated rapidly, causing the
Yankee bond market to experience substantial losses in select issues.
Furthermore, because credit ratings in the region have been significantly
downgraded, it has been very difficult for Asian governments and corporations to
issue new bonds to finance their ongoing operations.
 
Long-term U.S. interest rates fell as a result of the immediate flight to
quality and the longer-run implications for slower domestic growth and lower
inflation. The five-year U.S. Treasury, for example, declined by 67 basis points
(one basis point equals 1/100th of a percent) during the period, from 6.37% to
5.70%.
 
SMART STRATEGIES LEAD TO SOLID FUND RETURNS
In absolute terms, all of The One Group bond funds enjoyed share price increases
and solid total returns due to the declining interest rate environment in the
second half of the year. Funds with longer durations and strong exposure to U.S.
government securities performed the best. (Duration is a measure of a fund's
sensitivity to interest rate changes. A higher number indicates greater
sensitivity; a lower number indicates less sensitivity.) Funds with exposure to
corporate and Yankee bonds posted gains, but they lagged their competitors.
 
We attribute the funds' relatively strong performance to the strategies we
implemented early in the year. After the first quarter, when yields on 10-year
Treasury bonds approached 7%, we positioned our portfolios to take advantage of
the added yield available as well as the expected decline in rates. That
cautious stance early in the year allowed our fund managers to take advantage of
the weaker market at that time and position their portfolios for the friendlier
market that was to come later in the year.
 
Furthermore, as we entered 1997, tight yield spreads (or differences in yield
relative to risk) versus Treasuries and the extended length of the business
cycle caused us to take a very cautious stance toward the corporate sector. In
fact, we limited our corporate exposure during the year to securities in the
short to intermediate maturity range, which proved to be an appropriate
strategy. Overall, the corporate sector underperformed Treasuries, but in the
short to intermediate range, corporate performance matched that of the Treasury
market.
 
Finally, we remained positive toward mortgage-backed securities, which continued
to perform in line with or better than U.S. Treasuries until December, when
spreads widened due to lower mortgage rates and growing prepayment risks.
Overall, mortgages outperformed Treasuries by 92 basis points during the final
six months of the year.
 
MUNICIPAL MARKET REMAINS FAVORABLE
Technical supply and demand forces remained positive during the period, which
led to solid returns in the municipal bond market. The One Group municipal bond
funds posted relatively strong returns, reinforcing the continued performance
consistency of the fund family's national and state-specific municipal bond
funds.
 
Compared to the U.S. Treasury market, though, the municipal bond market was
unable to keep pace during the six-month period, as intermediate-term municipal
securities underperformed comparable Treasuries by about 50 basis points.
 
FLIGHT TO QUALITY BENEFITS MONEY MARKETS
Short-term interest rates remained relatively stable throughout the period. Late
in the year, though, the money markets benefited from reduced supply and the
strong demand that emerged after the financial crisis in Asia. As uncertainty
reigned, investors throughout the world sought safety in the form of
shorter-term, less volatile U.S. money market instruments.
 
All of The One Group money market funds maintained their stringent quality and
liquidity standards during the period and generated solid returns.
 
FOCUS REMAINS ON VOLATILITY
Low inflation and slowing domestic growth should lead to lower interest rates in
1998. At the same time, we expect price volatility to increase, which will cause
us to maintain a fairly cautious stance in terms of duration, credit quality and
overall risk management.
 
While corporate bonds may remain under pressure in 1998, we still expect them to
offer good performance versus other sectors, as corporate America remains strong
and any weakness will likely be modest. Mortgage-backed securities and municipal
securities also may be under pressure due to rising prepayments and refinancing
concerns. Municipals will be aided to some degree by continued strong supply and
demand influences. In the mortgage-sector we will look for issues offering good
structure, or less prepayment risk.
 
For individual investors, the key to success in this type of environment is to
diversify. Find a portfolio mix that suits your objectives, and stick with it
for the long haul. And remember, volatility can create attractive opportunities,
particularly for those of us who take the time to apply a long-term process and
orientation to our strategic thinking and to our management of money.

2. SIGNIFICANT ACCOUNTING POLICIES:
 
   The following is a summary of significant accounting policies followed by the
   Trust in the preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.
 
       SECURITY VALUATION
 
       Debt securities (other than short-term investments maturing in 60 days or
       less), including municipal securities, are valued on the basis of
       valuations provided by dealers or by an independent pricing service
       approved by the Board of Trustees. Short-term investments maturing in 60
       days or less are valued at amortized cost, which approximates market
       value. Futures contracts are valued at the settlement price established
       each day by the board of trade or an exchange on which they are traded.
       Options traded on an exchange are valued using the last sale price or, in
       the absence of a sale, the last offering price. Options traded
       over-the-counter are valued using dealer-supplied valuations. Investments
       for which there are no such quotations or valuations are valued at fair
       value as determined in good faith by the Fair Value Committee, which is
       comprised of members from Banc One Investment Advisors Corporation (the
       "Advisor") and the The One Group Services Company (the "Administrator"),
       under the direction of the Board of Trustees.

NOTES TO FINANCIAL STATEMENTS, CONTINUED                       DECEMBER 31, 1997
(Unaudited)
 
       REPURCHASE AGREEMENTS
 
       The Funds may invest in repurchase agreements with institutions that are
       deemed by the Advisor to be of good standing and creditworthy under
       guidelines established by the Board of Trustees. Each repurchase
       agreement is recorded at cost. The Fund requires that the securities
       purchased in a repurchase agreement transaction be transferred to the
       custodian in a manner sufficient to enable the Fund to obtain those
       securities in the event of a counterparty default. The seller, under the
       repurchase agreement, is required to maintain the value of the securities
       held at not less than the repurchase price, including accrued interest.
       Repurchase agreements are considered to be loans by a fund under the 1940
       Act.
 
       WRITTEN OPTIONS
 
       The Funds may write covered call or secured put options for which
       premiums received are recorded as liabilities and are subsequently
       adjusted to the current value of the options written. Premiums received
       from writing options which expire are treated as realized gains. Premiums
       received from writing options, which are either exercised or closed, are
       offset against the proceeds received or amount paid on the transaction to
       determine realized gains or losses.
 
       FUTURES CONTRACTS
 
       The Funds may enter into futures contracts for the delayed delivery of
       securities at a fixed price at some future date or for the change in the
       value of a specified financial index over a predetermined time period.
       Cash or securities are deposited with brokers in order to maintain a
       position. Subsequent payments made or received by the Fund based on the
       daily change in the market value of the position are recorded as
       unrealized appreciation or depreciation until the contract is closed out,
       at which time the appreciation or depreciation is realized.
 
       INDEXED SECURITIES
 
       The Funds may invest in indexed securities whose value is linked either
       directly or inversely to changes in foreign currencies, interest rates,
       commodities, indices or other reference instruments. Indexed securities
       may be more volatile than the referenced instrument itself, but any loss
       is limited to the amount of the original investment.
 
       MORTGAGE ROLLS
 
       The Funds may enter into mortgage "dollar rolls" in which the Fund sells
       mortgage-backed securities for delivery in the current month and
       simultaneously contracts to repurchase substantially similar securities
       on a specified future date. During the roll period, the Fund forgoes
       principal and interest paid on the mortgage-backed securities. The Fund
       is compensated by fee income or the difference between the current sales
       price and the lower forward price for the future purchase.
 
       SECURITIES LENDING
 
       To generate additional income, the Funds may lend up to 33% of securities
       in which they are invested pursuant to agreements requiring that the loan
       be continuously secured by cash, U.S. Government or U.S. Government
       Agency securities, shares of an investment trust or mutual fund, or any
       combination of cash and such securities as collateral equal at all times
       to at least 100% of the market value plus accrued interest on the
       securities lent. The Funds continue to earn interest on securities lent
       while simultaneously seeking to earn interest on the investment of
       collateral. Collateral is marked to market daily to provide a level of
       collateral at least equal to the market value of securities lent. There
       may be risks of delay in recovery of the securities or even loss of
       rights in the collateral should the borrower of the securities fail
       financially. However, loans will be made only to borrowers deemed by the
       Advisor to be of good standing and creditworthy under guidelines
       established by the Board of Trustees and when, in the judgment of the
       Advisor, the consideration which can be earned currently from such
       securities loans justifies the attendant

       risks. Loans are subject to termination by the Funds or the borrower at
       any time, and are, therefore, not considered to be illiquid investments.
       As of December 31, 1997 the Funds had no securities on loan.
 
       SECURITY TRANSACTIONS AND RELATED INCOME
 
       Security transactions are accounted for on a trade date basis. Net
       realized gains or losses from sales of securities are determined on the
       specific identification cost method. Interest income and expenses are
       recognized on the accrual basis. Dividends are recorded on the
       ex-dividend date. Interest income, including any discount or premium, is
       accrued as earned using the effective interest method.
 
       EXPENSES
 
       Expenses directly attributable to a Fund are charged directly to that
       Fund, while the expenses which are attributable to more than one fund of
       the Trust are allocated among the respective Funds. Each class of shares
       bears its pro-rata portion of expenses attributable to its series, except
       that each class separately bears expenses related specifically to that
       class, such as distribution fees.
 
       DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
       Dividends from net investment income are declared daily and paid monthly
       for the Funds. Net realized capital gains, if any, are distributed at
       least annually. Dividends are declared separately for each class. No
       class has preferential dividend rights; differences in per share dividend
       rates are due to differences in separate class expenses.
 
       Distributions from net investment income and from net capital gains are
       determined in accordance with income tax regulations which may differ
       from generally accepted accounting principles. These differences are
       primarily due to differing treatments for mortgage-backed securities,
       expiring capital loss carryforwards, and deferrals of certain losses.
       Permanent book and tax basis differences have been reclassified among the
       components of net assets.
 
       FEDERAL INCOME TAXES
 
       The Trust treats each Fund as a separate entity for Federal income tax
       purposes. Each Fund intends to continue to qualify as a regulated
       investment company by complying with the provisions available to certain
       investment companies as defined in applicable sections of the Internal
       Revenue Code, and to make distributions from net investment income and
       from net realized capital gains sufficient to relieve it from all, or
       substantially all, Federal income taxes.
 
3. SHARES OF BENEFICIAL INTEREST:
 
   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares and any series may be classified or
   reclassified into one or more classes. The Trust is registered to offer forty
   series and five classes of shares: Fiduciary Class, Class A, Class B, Class C
   and Service. Currently, the Trust consists of thirty-three active Funds. The
   Funds are each authorized to issue Fiduciary Class, Class A, Class B, and
   Class C Shares. Class A Shares are subject to initial sales charges, imposed
   at the time of purchase, in accordance with the Funds' prospectus. Certain
   redemptions of Class B and Class C Shares are subject to contingent deferred
   sales charges in accordance with the Funds' prospectus. As of December 31,
   1997, there were no shareholders in Class C of the Funds except for the
   Municipal Income Fund. Shareholders are entitled to one vote for each full
   share held and will vote in the aggregate and not by class or series, except
   as otherwise expressly required by law or when the Board of Trustees has
   determined that the matter to be voted on affects only the interest of
   shareholders of a particular class or series. The following is a summary of
   transactions in Fund shares for the periods ended December 31, 1997 and June
   30, 1997:

4. INVESTMENT ADVISORY, ADMINISTRATIVE, AND DISTRIBUTION AGREEMENTS:
 
   The Trust and the Advisor are parties to an investment advisory agreement
   under which the Advisor is entitled to receive an annual fee, computed daily
   and paid monthly, equal to the following percentages of the Funds' average
   net assets: 0.60% of the Intermediate Tax-Free Bond Fund, the Ohio Municipal
   Bond Fund and the Louisiana Municipal Bond Fund; and 0.45% of the Municipal
   Income Fund, the Kentucky Municipal Bond Fund, the Arizona Municipal Bond
   Fund and the West Virginia Municipal Bond Fund.
 
   The Trust and the Administrator, a wholly-owned subsidiary of The BISYS
   Group, Inc., are parties to an administrative agreement under which the
   Administrator provides services for a fee that is computed daily and paid
   monthly, at an annual rate of 0.20% on the first $1.5 billion of Trust net
   assets (excluding the Investor Growth Fund, the Investor Growth & Income
   Fund, the Investor Conservative Fund , and the Investor Balanced Fund, the
   "Investor Funds" and the Treasury Only Money Market Fund and the Government
   Money Market Fund, the "Institutional Money Market Funds"); 0.18% on the next
   $0.5 billion of Trust net assets (excluding the Investor Funds and the
   Institutional Money Market Funds); and 0.16% of Trust net assets (excluding
   the Investor Funds and the Institutional Money Market Funds) over $2 billion.
   The Advisor also serves as Sub-Administrator to each fund of the Trust,
   pursuant to an agreement between the Administrator and the Advisor. Pursuant
   to this agreement, the Advisor performs many of the Administrator's duties,
   for which the Advisor receives a fee paid by the Administrator.
 
   The Trust and The One Group Services Company (the "Distributor") are parties
   to a distribution agreement under which shares of the Funds are sold on a
   continuous basis. Class A, Class B, and Class C Shares are subject to
   distribution and shareholder services plans (the "Plans") pursuant to Rule
   12b-1 under the 1940 Act. As provided in the Plans, the Trust will pay the
   Distributor a fee of 0.35% of the average daily net assets of Class A Shares
   of each of the Funds and 1.00% of the average daily net assets of the Class B
   and Class C Shares of each of the Funds. Currently, the Distributor has
   voluntarily agreed to limit payments under the Plans to 0.25%, 0.90% and
   0.90% of average daily net assets of the Class A , Class B and Class C
   Shares, respectively, of each Fund. Up to 0.25% of the fees payable under the
   Plans may be used as compensation for shareholder services by the Distributor
   and/or financial institutions and intermediaries. Fees paid under the Plans
   may be applied by the Distributor toward (i) compensation for its services in
   connection with distribution assistance or provision of shareholder services;
   or (ii) payments to financial institutions and intermediaries such as banks
   (including affiliates of the Advisor), brokers, dealers and other
   institutions, including the Distributor's affiliates and subsidiaries as
   compensation for services or reimbursement of expenses incurred in connection
   with distribution assistance or provision of shareholder services. Fiduciary
   Class Shares of each Fund are offered without distribution fees. For the six
   months ended December 31, 1997, the Distributor received $684,478 from
   commissions earned on sales of Class A Shares and redemptions of Class B and
   Class C Shares, of which the Distributor reallowed $684,217 to affiliated
   broker/dealers of the Funds.
 
   Certain officers of the Trust are affiliated with the Administrator. Such
   officers receive no compensation from the Funds for serving in their
   respective roles.

6. FINANCIAL INSTRUMENTS:
 
   Investing in financial instruments such as written options, futures,
   structured notes and indexed securities involves risks in excess of the
   amounts reflected in the Statement of Assets and Liabilities. The face or
   contract amounts reflect the extent of the involvement the Funds have in the
   particular class of instrument. Risks associated with these instruments
   include an imperfect correlation between the movements in the price of the
   instruments and the price of the underlying securities and interest rates, an
   illiquid secondary market for the instruments or inability of counterparties
   to perform under the terms of the contract. The Funds enter into these
   contracts primarily as a means to hedge against adverse fluctuation in
   securities.
 
7. CONCENTRATION OF CREDIT RISK:
 
   The Kentucky, Ohio, Louisiana, Arizona and West Virginia Municipal Bond Funds
   invest primarily in debt obligations issued by the respective States and
   their political subdivisions, agencies and public authorities to obtain funds
   for various public purposes. The Funds are more susceptible to economic and
   political factors adversely affecting issuers of the state's specific
   municipal securities than are municipal bond funds that are not concentrated
   in these issuers to the same extent.
 
8. CONVERSION OF COMMON TRUST FUNDS:
 
   On December 19, 1997, the net assets of certain common trust funds managed by
   the Advisor were exchanged in a tax-free conversion for shares of the
   corresponding One Group Funds. The transaction was accounted for by a method
   followed for tax purposes in a tax-free business combination. The following
   is a summary of shares
