THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1996
 
WE ARE PLEASED TO PRESENT THIS SEMI-ANNUAL REPORT FOR THE ONE
GROUP-REGISTERED TRADEMARK- 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, 1996, THROUGH DECEMBER 31, 1996.
 
DEAR VALUED SHAREHOLDERS:
Thank you for your continued support of The One Group Family of Mutual Funds.
 
1996 proved to be a rewarding year for stock investors, and a challenging one
for bond investors. Stocks maintained the strength they exhibited during 1995
and posted impressive double-digit returns. Bond returns, on the other hand,
slipped back into the low single digits, as the market was plagued with
volatility.
 
As strong as the stock market's returns were during 1996, and as disappointing
as the bond market's results were, it's important to keep performance--whether
good or bad--in perspective. Returns in any single year shouldn't influence your
long-term investment strategy.
 
It's highly unlikely that, over the long term, the stock market will remain as
strong as it has been during the past two years, or that the bond market will
remain as volatile. While returns may fluctuate over the short term, over the
long term the markets tend to adjust for periodic ups and downs so that
performance evens out.
 
These market dynamics underscore the importance of three key investment
strategies:
- - MAINTAINING A LONG-TERM PERSPECTIVE. Don't let short-term returns distract you
  from your long-term strategy. Let time work for your investment portfolio.
  After all, it's time, not timing, that allows investments to realize their
  full potential.
- - ASSET ALLOCATION. Spreading your investment dollars among stocks, bonds and
  money market securities according to your goals, time frame and risk tolerance
  exposes your money to opportunities from each major asset class.
- - DIVERSIFICATION. Investing in a variety of securities within each asset class
  may enhance your returns while helping to reduce overall portfolio risk.
 
We believe that following these principles is critical to long-term investment
success. Nevertheless, it sometimes is difficult for individual investors to
implement these strategies in their own investment plans. The One Group is
always working on new ways to make investing easy and convenient. And now,
taking advantage of these investment techniques has never been simpler.
 
Four new funds--THE ONE GROUP INVESTOR FUNDS-- take the time and complexity out
of allocating your assets and assembling a diversified investment portfolio.
They offer a convenient way to enjoy asset allocation and broad diversification
from ONE investment.
 
Each of The One Group Investor Funds is targeted toward a specific investment
objective, such as growth, income or a combination of the two. In striving to
meet these objectives, the investment professionals managing The One Group
Investor Funds invest in a combination of mutual funds from The One Group
family. So, by investing in the SINGLE One Group Investor Fund best suited to
your goals, you enjoy instant diversification and professional asset allocation.
 
The One Group Investor Funds are suitable for various investment goals,
including one of the most important--retirement. Because they offer a single
source for asset allocation and broad diversification, they may be ideal
investments for THE ONE GROUP IRA.
 
The One Group IRA can be one of the smartest ways to save for retirement:
- - All workers AND non-working spouses may contribute up to $2,000 A YEAR.
- - You accumulate TAX-DEFERRED EARNINGS during your working years.
- - For certain investors, some or all of the $2,000 annual IRA contribution limit
  may be TAX-DEDUCTIBLE.
 
There's still time to make your IRA investment for the 1996 income tax year; the
deadline is April 15. All it takes is a minimum of $25 to set up your IRA, as
long as you sign up for systematic investing. Otherwise, the minimum is $250.
And, if you maintain a balance of at least $1,000, The One Group will waive the
annual IRA maintenance fee.

THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1996
 
ECONOMY STAYS ON STEADY COURSE
Economic growth during the second half of 1996 started out on unstable ground,
with inventory accumulation representing approximately 75% of the third
quarter's 2.1% GDP growth. When growth is backed by a surge in inventories, it
is not sustainable. During the fourth quarter, though, a decline in the level of
reported inventories revealed virtually no contribution from this component
toward the 4.7% overall growth rate. This demonstrated that the composition of
growth as the year ended was much more solid than it was in the third quarter.
 
EXPECTED FED ACTION DOESN'T MATERIALIZE
While short-term interest rates, such as the three-month Treasury bill rate,
seem to have remained relatively stable from the beginning of the six-month
period, when they were 5.23%, to the end, when they were 5.17%, there was, in
fact, significant volatility in between. After a surge in GDP growth in the
second quarter--to 4.7%-- the bond market became convinced that a tightening by
the Federal Reserve was necessary, causing rates on the two-year Treasury note
to climb as high as 6.43%. The Fed, however, left its monetary policy unchanged,
and short-term rates came back down.
 
With regard to adjusting monetary policy, the Fed remained idle during the
second half of the year. In fact, the only Fed action for all of 1996 came on
Jan. 31, when it cut the federal funds rate by 0.25%. Nevertheless, the Fed
continued to nurture economic growth during the second half, as it was able to
largely ignore the tightness of the labor market and increased labor costs that
characterized the period. The Fed's current philosophy continues to be somewhat
preemptive in nature, but not as preemptive as it was in 1994, when it first
introduced this philosophy to the financial markets.
 
LONG-TERM RATES DECLINE
Investor concerns about stronger economic growth diminished during the final few
months of the year, as the market became more hopeful that economic growth
eventually would slow down. As a result, long-term interest rates toward the
latter half of the year proceeded to decline even in the wake of higher
inflation.
 
Consumer prices slowly increased during the period, ending the year up 3.3% on a
year-over-year basis. Prices at the beginning of the six-month period were
rising only 2.8% on a year-over-year basis. The decline in long-term rates
occurred on the bond market's expectation that inflation in 1997 would be a lot
more subdued, and slower economic growth would take some wind out of
inflationary pressures.
 
The decline in long-term interest rates during the second half of the year
continued to add overall support to the country's stock market. In addition, it
may have offered the housing sector a helping hand. In November, for example,
housing starts posted a gain of 9.3%, which represented the highest monthly
growth rate since July 1995, when housing starts were up 11.5%. Nevertheless, by
year-end, we observed that poor weather in the West caused December's housing
starts to plunge by 12.2%.
 
WHAT'S IN STORE FOR 1997
After growing at a rate of 2.5% in 1996, we think the economy may slow down in
1997, as growth softens. Some of this slowdown is likely to be caused by a
continued dampening of growth in consumer credit.
 
As growth slows, consumer prices should increase by approximately 3.5% (on a
year-over-year basis) in 1997, due to growing labor cost pressures. This factor
is likely to push long-term interest rates up during the year. After starting
the year at 6.5%, we believe that the 30-year Treasury bond may peak during the
second half of the year and then fall back to approximately 6.9% in the fourth
quarter if economic growth slows.
 
One of the major uncertainties for the bond market in the first half of 1997
will be whether or not the tight labor market persists, and, furthermore,
whether it will result in much firmer consumer prices. Current bond prices
suggest that the market remains optimistic, but in the event that these
pressures translate into much higher prices, the bond market may encounter great
difficulty in the first half of the year.
 
We suspect that the Federal Reserve may combat rising consumer prices with an
increase in short-term interest rates. Our preliminary projections show that the
federal funds rate may move up during the first half of 1997, which should place
some downward pressure on stock prices.

NOTES TO FINANCIAL STATEMENTS                                  DECEMBER 31, 1996
(Unaudited)
 
1.  ORGANIZATION:
 
    The  One Group (the "Trust") is  registered under the Investment Company Act
    of 1940, as amended (the "1940 Act"), as a diversified, open-end  investment
    company  established  as  a  Massachusetts  business  trust.  The  Trust  is
    registered to offer four classes of shares: Fiduciary, Class A, Class B, and
    Service.  The  Trust  currently  consists   of  thirty  active  funds.   The
    accompanying  financial statements and financial highlights are those of the
    U.S. Treasury Securities Money Market Fund, the Prime Money Market Fund, the
    Municipal Money  Market  Fund, and  the  Ohio Municipal  Money  Market  Fund
    (individually,  a "Fund";  collectively, the "Funds")  only. Each  Fund is a
    diversified mutual fund, except the  Ohio Municipal Money Market Fund  which
    is non-diversified.
 
    The  Trust  entered  into  an  Agreement  and  Plan  of  Reorganization (the
    "Agreement")  with  the  Paragon  Portfolio  ("Paragon"),  a   Massachusetts
    business  trust. Pursuant to the Agreement all of the assets and liabilities
    of each Paragon Fund transferred to a fund of The One Group in exchange  for
    shares of the corresponding fund of The One Group. Changes in net assets and
    financial  highlights  for periods  prior to  the reorganization,  March 25,
    1996, are presented for the funds of The One Group only.
 
    The Funds' investment objectives are as follows:

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
 
     Securities  are  valued utilizing  the amortized  cost method  permitted in
     accordance with Rule  2a-7 under  the 1940  Act. Under  the amortized  cost
     method,  discount  or  premium is  amortized  on  a constant  basis  to the
     maturity of the security. In addition,  the Funds may not (a) purchase  any
     instrument  with a remaining  maturity greater than  thirteen months unless
     such instrument  is  subject  to  a  demand  feature,  or  (b)  maintain  a
     dollar-weighted average maturity which exceeds 90 days.

     REPURCHASE AGREEMENTS
 
     The  Funds may invest  in repurchase agreements  with institutions that the
     Fund's investment adviser has determined are creditworthy. Each  repurchase
     agreement  is  recorded  at cost.  The  Fund requires  that  the securities
     purchased in a repurchase 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 in the 1940 Act.
 
     SECURITY TRANSACTIONS AND RELATED INCOME
 
     Security transactions are accounted for on a trade date basis. Net realized
     gains  or  losses on  sales of  securities are  determined on  the specific
     identification cost method. Interest income and expenses are recognized  on
     the  accrual basis. Interest income, including  any discount or premium, is
     accrued as earned using the effective interest method.
 
     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 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 Adviser to be of good standing and
     creditworthy under  guidelines established  by the  Board of  Trustees  and
     when,  in  the judgement  of the  Adviser, the  consideration which  can be
     earned currently from such securities  loans justifies the attendant  risk.
     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, 1996,  the following Fund  had securities  with the following
     market values on loan (amount in thousands):

U.S. Treasury Securities Money Market Fund..................  $      162,686
</TABLE>
 
     The loaned securities were fully collateralized by cash and U.S. Government
     securities as of December 31, 1996.
 
     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.
     Net  income  for this  purpose consists  of  interest accrued  and discount
     earned (including both  original issue discount  and market discount)  less
     amortization  of  any market  premium  and accrued  expenses.  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  generally  due  to
     differences in separate class expenses.
 
     Net  investment income and net capital gain distributions are determined in
     accordance with  income tax  regulations which  may differ  from  generally
     accepted  accounting  principles. These  differences  are primarily  due to
     differing treatments of expiring  capital loss carryforwards and  deferrals
     of  certain losses. Permanent  book and tax differences,  if any, have been
     reclassified among the components of net assets.
 
     ORGANIZATION COSTS
 
     Costs incurred by the Trust in connection with its organization,  including
     the  fees  and  expenses  of  registering  and  qualifying  its  shares for
     distribution  have  been  deferred  and  are  being  amortized  using   the
     straight-line  method  over  a  period of  five  years  beginning  with the
     commencement of each Fund's operations. All such costs have been  allocated
     among  the funds of the Trust pro-rata, based on the relative net assets of
     each fund. In the event that any of the initial shares are redeemed  during
     such  period by any holder thereof, the  related Fund will be reimbursed by
     such holder for any unamortized organization costs in the proportion as the
     number of initial  shares being  redeemed bears  to the  number of  initial
     shares outstanding at the time of redemption.
 
     FEDERAL INCOME TAXES
 
     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 of net  investment
     income and 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. Currently, shares of the Trust are
    registered to be offered through  forty series and four classes:  Fiduciary,
    Class  A, Class B, and Service. During the year ended June 30, 1995, Service
    Shares transferred to Class A Shares. As of December 31, 1996 there were  no
    shareholders in the Service Class. 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 six months ended December 31,
    1996 and the year ended June 30, 1996:

    The Trust and Banc One Investment Advisors Corporation (the "Adviser"),  are
    parties  to  an investment  advisory agreement  under  which the  Adviser is
    entitled to receive an annual fee, computed daily and paid monthly, equal to
    0.35% of the average daily net assets of the U.S. Treasury Securities  Money
    Market Fund, the Prime Money Market Fund and the Municipal Money Market Fund
    and 0.30% of the average daily net assets of the Ohio Municipal Money Market
    Fund.
 
    The  Trust  and  The One  Group  Services Company  (the  "Administrator"), a
    wholly-owned subsidiary  of  The  BISYS  Group,  Inc.,  are  parties  to  an
    administration 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
    each  Fund's average daily net assets on the first $1.5 billion of Trust net
    assets (excluding the  Investor Growth  Fund, the Investor  Growth &  Income
    Fund,  the Investor Conservative Growth 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%  on Trust net

   the  Trust,  pursuant  to  an agreement  between  the  Administrator  and the
    Adviser. Pursuant  to  this agreement,  the  Adviser performs  many  of  the
    Administrator's  duties, for  which the Adviser  receives a fee  paid by the
    Administrator. Prior  to  March 26,  1996,  Goldman Sachs  Asset  Management
    served  as administrator of Paragon under  essentially the same terms as the
    current administration agreement.
 
    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  Shares, Class B Shares  and Service Class 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,  1.00% of the average daily
    net assets of  Class B  and 0.75%  of the average  daily net  assets of  the
    Service  Class Shares of each of  the Funds. The Distributor has voluntarily
    agreed to  limit payments  under the  Plans to  0.25% of  average daily  net
    assets  of the Class  A Shares of each  Fund and 0.55%  of average daily net
    assets of the Service  Class Shares of  each Fund. Up to  0.25% of the  fees
    payable  under the Plans may be used as compensation of 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
    Adviser),   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.
 
    Prior  to January 2,  1996, Premier Investment  Advisors, L.L.C. ("Premier")
    served  as  investment  adviser  and  Goldman  Sachs  &  Company  served  as
    distributor to Paragon. Pursuant to the approval of the Board of Trustees of
    Paragon  on  October 31,  1995 and  its Shareholders  on December  20, 1995,
    Paragon entered into an investment advisory agreement with the Adviser and a
    distribution agreement with the Distributor  effective January 2, 1996.  The
    Terms  of  the  investment advisory  agreements  with Premier  and  with the
    Adviser and the distribution agreements with Goldman Sachs & Company and the
    Distributor were substantially the same.  Certain officers of the Trust  are
    affiliated  with the  Administrator. Such  officers receive  no compensation
    from the Funds for serving in their respective roles.
 
    The Adviser, Administrator and the Distributor voluntarily agreed to waive a
    portion of their fees and to  reimburse the Funds for certain expenses.  For
    the  six months ended December 31, 1996,  fees in the following amounts were
    waived from the Funds (amounts in thousands):

5.  CONCENTRATION OF CREDIT RISK:
 
    The Ohio Municipal Money Market  Fund invests primarily in debt  obligations
    issued  by the  State of Ohio  and its political  subdivisions, agencies and
    public authorities to obtain funds for various public purposes. The Fund  is
    more  susceptible  to  economic and  political  factors  adversely affecting
    issuers of  Ohio's specific  municipal securities  than are  municipal  bond
    funds that are not concentrated in these issuers to the same extent.

6.  REORGANIZATION:
 
    The  Trust  entered an  Agreement and  Plan  of Reorganization  with Paragon
    pursuant to which  all of the  assets and liabilities  of each Paragon  Fund
    transferred  to  a fund  of  The One  Group in  exchange  for shares  of the
    corresponding fund of The One Group. The Paragon Treasury Money Market  Fund
    transferred its assets and liabilities to the U.S. Treasury Securities Money
    Market  Fund. The reorganization, which qualified as a tax-free exchange for
    federal income  tax purposes,  was  completed on  March 25,  1996  following
    approval  by shareholders of the Paragon  Portfolio at a special shareholder
    meeting. The following is  a summary of shares  outstanding, net assets  and
    net asset value per share immediately before and after the reorganization:
