                 The One Group Treasury Only Money Market Fund
Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The seven-day yield on The One Group Treasury Only Money Market Fund was 5.04%
on June 30, 1998, down slightly from 5.12% on June 30, 1997.
 
WHAT CONTRIBUTED TO THE FUND'S FAIRLY STABLE YIELD?
The Fund's yield reflects the relative stability in interest rates brought on by
the Federal Reserve's unchanged monetary policy. Rate movements during the year
were fairly moderate. They reflected changing views on economic strength and
whether that strength would lead to inflationary pressures requiring Federal
Reserve action.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
The portfolio continued to benefit from a "barbell" maturity structure, a common
technique that involves investing in securities at the long and short ends of a
particular maturity range instead of those with intermediate maturities.
 
This strategy led to an average maturity of 49 days on June 30, 1998, enabling
the Fund to maintain its "AAA" average quality rating--the best possible--from
Standard & Poor's and Moody's Investors Service. This rating indicates that the
Fund's securities are of the highest quality and offer the lowest risk. In order
to receive this rating, a fund must have an average maturity no greater than 60
days.
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Economic activity and its influences on Federal Reserve policies may have a
direct effect on the Fund over the next year. Over the near term, strong
domestic demand is likely to be offset by the Asian crisis. This will require
the Federal Reserve to be diligent in directing monetary policy. This outlook
warrants continued caution so the Fund can be positioned to benefit from any
action the Federal Reserve may take.

                   The One Group Government Money Market Fund
Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The seven-day yield on The One Group Government Money Market Fund was 5.56% on
June 30, 1998, up slightly from 5.30% on June 30, 1997.
 
WHAT CONTRIBUTED TO THE FUND'S FAIRLY STABLE YIELD?
The Fund's yield reflects the relative rate stability caused by the Federal
Reserve's unchanged monetary policy. Rate movements throughout the year were
fairly moderate. They reflected changing views on economic strength and whether
that strength would lead to inflationary pressures requiring Federal Reserve
action.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
The Fund was invested primarily in agency securities because they offered a
yield advantage of 10 to 15 basis points over Treasuries and repurchase
agreements (one basis point equals 1/100th of a percent). The Fund also held
between 15% and 20% of its assets in floating-rate securities, which offered
yields that changed on a weekly basis. This position helped the Fund quickly
take advantage of rising interest rates.
 
The portfolio continued to benefit from a "barbell" maturity structure, a common
strategy that involves favoring securities at the long and short ends of a
particular maturity range over those with intermediate maturities. At the "long"
end, we purchased securities with maturities of six months to one year, and at
the "short" end, we held overnight repurchase agreements. The longer securities
allowed the Fund to benefit from the steepness of the yield curve (which occurs
when securities with longer maturities offer relatively higher yields), while
the overnight securities helped the Fund maintain a high degree of liquidity.

The Fund's barbell structure contributed to an average maturity of 37 days on
June 30, 1998, compared to 72 days on June 30, 1997.
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Economic activity and its influences on Federal Reserve policies may have a
direct effect on the Fund over the next year. Over the near term, strong
domestic demand is likely to be offset by the Asian crisis. This will require
the Federal Reserve to be diligent in directing monetary policy. This outlook
warrants continued caution so the Fund can be positioned to benefit from any
action the Federal Reserve may take.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 1998
 
1. ORGANIZATION:
 
   The One Group (the "Trust") is registered under the Investment Company Act of
   1940, as amended (the "1940 Act"), as an open-end investment company
   established as a Massachusetts business trust. The accompanying financial
   statements and financial highlights are those of the Treasury Only Money
   Market Fund and the Government Money Market Fund (individually a "Fund",
   collectively the "Funds") only. The Funds are diversified mutual funds and
   are not offered in multiple classes.
 
   The Funds' investment objectives are as follows:
 
<TABLE>
<CAPTION>
      FUND                                  OBJECTIVE
      ----                                  ---------
      <S>                                   <C>
      Treasury Only Money Market Fund       High current income with liquidity and stability of
                                            principal.
 
      Government Money Market Fund          High current income with liquidity and stability of
                                            principal.
</TABLE>
 
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 397 days unless 
        such instrument is subject to a demand feature, or (b) maintain a 
        dollar-weighted average maturity which exceeds 90 days.
 
        REPURCHASE AGREEMENTS
 
        The Government Money Market Fund may invest in repurchase agreements 
        with institutions that are deemed by Banc One Investment Advisors 
        Corporation (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.
 
        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. Interest income, including any discount
        or premium, is accrued as earned using the effective interest method.

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 1998
 
        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 
        June 30, 1998, the following Funds had securities with the following 
        amortized cost on loan (amounts in thousands):

            Government Money Market Fund............     $26,066                --         $ 25,551
</TABLE>
 
       The loaned securities were fully collateralized by cash and U.S.
       Government securities as of June 30, 1998.
 
       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.
 
       DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
       Dividends from net investment income are declared daily and paid monthly.
       Net investment 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.
 
       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 expiring capital loss
       carryforwards and deferrals of certain losses. Permanent book and tax
       basis differences, if any, 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 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. The Trust is registered to offer forty
   series and five classes of shares: Fiduciary, Class A, Class B, Class C and
   Service Class. Currently, the Trust consists of thirty-three active Funds,
   and not all Funds offer all classes of shares. 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.
 
4. INVESTMENT ADVISORY, ADMINISTRATIVE AND DISTRIBUTION AGREEMENTS:
 
   The Trust and Advisor are parties to an investment advisory agreement under
   which the Advisor is entitled to receive a fee, computed daily and paid
   monthly, equal to 0.08% of the average daily net assets of each Fund.
 
   The Trust and The One Group Services Company (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 0.05% of
   each Fund's average daily net assets. 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 One Group Services Company (the "Distributor") and the Trust are parties
   to a distribution agreement under which shares of the Funds are sold on a
   continuous basis. No compensation is paid to the Distributor for distribution
   services for 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.
 
5. FEDERAL TAX INFORMATION (UNAUDITED):
 
   At June 30, 1998 the following Funds have capital loss carryforwards which
   are available to offset future capital gains, if any (amounts in thousands):

6. SUBSEQUENT EVENTS
 
   On May 21, 1998, the Board of Trustees approved an agreement and plan of
   reorganization and liquidation ("the Plan") with the Marquis Family of Funds
   (the "Marquis Funds"). Under the Plan, the assets and liabilities of each
   Marquis fund were transferred to a comparable One Group fund. Shares of the
   comparable One Group fund were distributed to the Marquis shareholders in a
   complete liquidation of each Marquis fund. A special Shareholder Meeting to
   approve the plan was held on July 30, 1998. In a tax-free exchange on August
   10, 1998, $69,923,110 of the Marquis Institutional Money Market Fund were
   exchanged for 69,923,110 shares of the One Group Treasury Only Money Market
   Fund.

Report of Independent Accountants

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds
 
In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Treasury Only Money Market Fund
and the Government Money Market Fund (two series of The One Group Family of
Mutual Funds), at June 30, 1998, the results of each of their operations for the
period then ended, the changes in each of their net assets for the periods
presented and the financial highlights for each of the periods presented, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of The One Group Family of Mutual Funds'
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at June 30, 1998 by correspondence with the custodian
and brokers, provide a reasonable basis for the opinion expressed above.
