ECONOMIC OUTLOOK
1999 was yet another year in which the U.S. economy demonstrated its remarkable
resiliency. The economy turned in another year of strong growth and low
inflation despite a major currency devaluation in Latin America and higher
interest rates in the U.S.

Despite low inflation, the Federal Reserve became more restrictive in 1999, with
three hikes in the federal funds rate. The central bank was concerned that labor
markets might be too tight, which could lead to the emergence of wage pressures
and eventually higher overall inflation.

Looking ahead to 2000, we see another good year for the U.S. economy. Because we
are still experiencing strong job growth, low inflation and high levels of
consumer confidence, it's a good bet that consumer spending will continue to
fuel healthy overall economic growth. Our forecast is that the economy will
expand by 3.6 percent in 2000 and that the current expansion (which began in
April 1991) will easily last until February, at which point it will become the
longest expansion in U.S. history.

We also are looking for inflation to remain low. We do expect the inflation rate
to gradually accelerate as wages begin to move higher, but we are not looking
for any dramatic spikes in inflation anytime in the near future. Still, as long
as labor markets remain this tight, the Federal Reserve is likely to remain on
alert. Until there is a significant and sustained loosening in the labor market,
the central bank will continue to be concerned about rising wages putting upward
pressure on the overall inflation rate. Because we expect that the unemployment
rate will stay close to its current low level throughout the year, and because
we are anticipating a slightly higher inflation rate, our forecast calls for
higher interest rates in 2000. On the whole, however, the outlook is very
positive. With strong growth and low inflation, the U.S. economy appears headed
for another solid year.

1. ORGANIZATION:

   The One Group Mutual Funds (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 Cash
   Management Money Market Fund, the Treasury Prime Cash Management Money Market
   Fund, the U.S. Government Securities Cash Management Money Market Fund, the
   Treasury Cash Management Money Market Fund and the Municipal Cash Management
   Money Market Fund, (individually, a "Fund"; collectively, the "Funds") only.
   Each Fund is a diversified mutual fund.

   The Funds' investment objectives are as follows:

</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 Funds (except the Treasury Prime Cash Management 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 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

(Unaudited)

     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 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 for both financial reporting and tax purposes using the
     straight-line amortized cost 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.
     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 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.

     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.

     DEFERRED ORGANIZATION COSTS

     Prior to June 30, 1998, 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, which are
     attributable to more than one fund of the Trust, have been allocated among
     the respective funds 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.

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
   fifty-four series and six classes of shares: Class I, Class A, Class B, Class
   C, Class S and Service Class. Currently, the Trust consists of forty-nine
   active funds. The Funds are each authorized to issue Class I and Class A
   shares only. Shareholders are entitled to one vote for each full share held
   and 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. See Schedules of Capital Stock Activity.

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 0.20% of the average daily net assets of the
   Funds.

   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
   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, Government Money Market Fund and the Institutional
   Prime 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 shares are subject to a distribution and
   shareholder services plan (the "Plan") pursuant to Rule 12b-1 under the 1940
   Act. As provided in the Plan, the Trust will pay the Distributor a fee of
   0.25% of the average daily net assets of Class A shares of each of the Funds.
   Up to 0.25% of the fees payable under the Plan may be used as compensation of
   shareholder services by the Distributor and/or financial institutions and
   intermediaries. Fees paid under the Plan 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. Class I shares of each Fund are offered
   without distribution fees.

   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. LINE OF CREDIT:

   The Trust and State Street Bank and Trust Company ("State Street") and a
   group of banks (collectively, the "Banks") entered into a financing agreement
   dated October 19, 1999. Under this agreement, the Banks provide an unsecured
   committed credit facility in the aggregate amount of $500 million. The credit
   facility is allocated, under the terms of the financing agreement, among the
   Banks. Advances under the agreement are taken primarily for temporary or
   emergency purposes, including the meeting of redemption requests that
   otherwise might require the untimely disposition of securities, and are
   subject to each Fund's borrowing restrictions. Interest on borrowings is
   payable at the Federal Funds Rate plus 0.50% on an annualized basis. Interest
   on borrowings during the period from and including December 15, 1999, to
   January 17, 2000, is payable at 0.50% plus the higher of the Fed Funds
   Effective Rate plus 0.50% or the Fed Funds Target Rate plus 1.50%. A
   commitment fee of 0.10% per annum will be incurred on the unused portion of
   the committed facility, which is allocated to all funds.

   At December 31, 1999, Municipal Cash Management Money Market Fund had
   $1,700,000 outstanding under this agreement. During the six months ended
   December 31, 1999, borrowings by the Funds under the Agreement were as
   follows (amounts in thousands):

   The average amount outstanding was calculated based on daily balances during
   the period.

6. DEFERRED TRUSTEES FEES:

   Independent Trustees of the Funds may participate in a Deferred Compensation
   Plan in which they may defer any or all compensation related to performance
   of their duties as a Trustee. All deferred compensation is paid by the Funds
   and invested into various One Group funds elected by each Trustee. The Plan
   is fully funded and therefore, the Funds bear no additional trustee expense
   over and above the normal cash compensation.

7. CONVERSION OF COMMON TRUST FUNDS:

   The net assets of certain common trust funds managed by First Chicago NBD
   Investment Management Company (an affiliate of the Advisor) were exchanged in
   a tax-free conversion for Class I shares of the corresponding Funds. The
   transactions were accounted for by a method followed for tax purposes in a
   tax-free business

8. PEGASUS REORGANIZATION:

   The Trust entered an agreement and plan of reorganization and liquidation
   ("the Reorganization") of the Pegasus Funds pursuant to which all of the
   assets and liabilities of each Pegasus Fund was transferred to a Fund of the
   One Group in exchange for shares of the corresponding Fund of the One Group.
   The Reorganization, which qualified as a tax-free exchange for Federal income
   tax purposes, was completed on March 28, 1999, following approval by
   shareholders of the Pegasus Funds at a special shareholder meeting. The
