ONE GROUP MUTUAL FUNDS                                         DECEMBER 31, 1999

STOCKS END YEAR ON STRONG NOTE
In general, most stock market averages finished 1999 on a strong note. For
example, both the S&P 500 Index and the Dow Jones Industrial Average posted
solid double-digit returns for an unprecedented fifth-consecutive year. For the
12 months ended December 31, 1999, the S&P posted a total return of 21.04%, and
the Dow showed a total return of 27.21%.

Perhaps the biggest stock market story of 1999 occurred on NASDAQ. The
technology-heavy index enjoyed a record-breaking year, increasing 85.6% during
1999. Even more amazing, more than half of that gain occurred after November 3,
the day the index topped the 3000 mark. NASDAQ's 1999 performance represents the
greatest single-year gain ever posted by a U.S. stock market index.

GROWTH SOARS, WHILE VALUE STRUGGLES
In terms of styles, large-capitalization growth stocks maintained their favored
status among investors, as evidenced by the S&P 500/BARRA Growth Index's six-
month total return of 15.56% and one-year total return of 28.25%, as of December
31, 1999. But, the fondness for growth stocks extended into other areas of the
market. The S&P MidCap 400/BARRA Growth Index posted a six-month total return of
18.99% and a one-year total return of 28.74%, as of December 31, 1999. Small-cap
growth stocks, as represented by the S&P SmallCap 600/BARRA Growth Index, posted
a six-month and one-year total return of 17.60% and 19.57%, respectively, for
the periods ended December 31, 1999.

Value stocks, in general, suffered a disappointing second half that capped off a
difficult year. Several factors worked against value stocks, including rising
interest rates, the dominance of the growth sector, and the frenzy for
high-flying technology stocks. As of December 31, 1999, large-capitalization
value stocks, as represented by the S&P 500/BARRA Value Index, offered a
six-month total return of -1.08% and a one-year total return of 12.72%.
Smaller-cap value stocks didn't fare nearly as well. For example, the S&P MidCap
400/ BARRA Value Index posted a six-month total return of -3.17% and a one-year
total return of 2.33%; and the S&P SmallCap 600/BARRA Value Index posted six-
month and one-year total returns of -5.00% and 3.03%, respectively, for the
periods ended December 31, 1999.

TECHNOLOGY STOCKS DRIVE GROWTH SURGE
While growth stocks enjoyed solid overall returns in the second half of 1999,
much of that performance was concentrated in a single sector--technology.
Investors demonstrated strong demand for fast-growing technology plays. In
particular, Internet-related and wireless communications-related sectors
attracted significant investments and offered spectacular performance.

Many non-technology sectors, including some traditional growth sectors, actually
suffered during the period. For example, the growth-oriented health care sector
posted negative returns.

INTERNATIONAL STOCKS ENJOY TURNAROUND
The second half of 1999 saw the international stock market, as measured by the
Europe, Australia and Far East Gross Domestic Product (EAFE GDP) Index, stage a
turnaround. In fact, the EAFE index outperformed the S&P 500 Index for the final
six months of 1999 and for the entire 12-month period ended December 31, 1999.
EAFE GDP's six-month and one-year total returns were 23.99% and 31.00%,
respectively.

Despite a slow start to 1999, due primarily to problems associated with the
euro, Europe staged a comeback in the second half of the year. Also, Asia's
recovery came quicker and stronger than most expected. The emerging markets also
offered strong performance.

ONE GROUP FUNDS STAY TRUE TO STYLES
By staying true to their disciplines and stated style objectives, most One Group
stock funds offered solid total returns for the six-month and one-year periods.

In the growth sector, our funds remained focused on companies with predictable
earnings streams and solid earnings growth prospects. Our value-oriented funds
focused on attractively priced stocks with improving fundamentals.

Despite the performance advantages in the technology sector, our funds stayed
true to their stated style and diversification objectives. Many of our funds
were able to benefit from the technology rally, but within the

guidelines of our disciplined strategies. We did not significantly alter our
sector weightings or chase the best-performing technology stocks to boost
short-term performance. Instead, we simply invested in those issues--in the
technology sector and all others--that our research efforts identified as good
long-term prospects. We believe this is a prudent long-term strategy, regardless
of what happens over short-term time periods.

OUTLOOK REMAINS GOOD
We believe that conditions remain favorable for continued stock market growth,
though probably not at the pace we've seen over the last several years. We think
that interest rates will continue their upward course, at least for the first
half of 2000. This should continue to put some pressure on the stock market.
Once rates subside, we hope to see market participation widen into the value
sector.

We believe that diversification will be a key strategy in 2000. Investors should
avoid the temptation to chase 1999's big winners and make sure they maintain a
broadly diversified equity portfolio that includes a variety of domestic and
international stocks.

</TABLE>

2. SIGNIFICANT ACCOUNTING POLICIES:

   The following is a summary of significant accounting policies followed by the
   Trust in 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

     Listed securities are valued at the latest available sales price on the
     principal exchange where such securities are traded. Unlisted securities or
     listed securities for which latest sales prices are not available are
     valued at the mean of the latest bid and ask price in the principal market
     where such securities are normally traded. Corporate debt securities and
     debt securities of U.S. issuers (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 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 mean of the latest bid and ask prices. Options
     traded over-the-counter are valued using dealer-supplied valuations.
     Investments for which there are no such quotations or valuations are
     carried at fair value as determined by the Pricing Committee which is
     comprised of members from Banc One Investment Advisors Corporation (the
     "Advisor") and The One Group Services Company (the "Administrator") under
     the direction of the Board of Trustees.

     FOREIGN CURRENCY TRANSLATION

     Investment valuations, other assets and liabilities initially expressed in
     foreign currencies are converted each business day into U.S. dollars based
     upon current exchange rates. Purchases and sales of foreign investments and
     income and expenses are converted into U.S. dollars based upon exchange
     rates prevailing on the respective dates of such transactions. That portion
     of realized gains or losses and unrealized appreciation or depreciation
     from investments due to fluctuations in foreign currency exchange rates is
     not separately disclosed. Such fluctuations are included with the net
     realized and unrealized gain or loss from investments.

     FORWARD FOREIGN CURRENCY CONTRACTS

     Forward foreign currency contracts are valued at the daily exchange rate of
     the underlying currency. Purchases and sales of forward foreign currency
     contracts having the same settlement date and broker are presented net on
     the Statement of Assets and Liabilities. The forward foreign currency
     exchange contracts are adjusted by the daily exchange rate of the
     underlying currency and any gains or losses are recorded for financial
     statement purposes as unrealized appreciation or depreciation until the
     contract settlement date. Gains or losses from the purchase or sale of
     forward foreign currency contracts having the same settlement date and
     broker are recorded as realized on the date of offset; otherwise gains or
     losses are recorded as realized on settlement date.

     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 under the 1940 Act.

     To generate additional income, the Funds may lend up to 33 1/3% 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,
     letters of credit or any combination of cash, such securities, shares, or
     letters of credit as collateral equal at all times to at least 100% of the
     market value plus accrued interest on the securities lent. The Funds
     receive payments from borrowers equivalent to the dividends and interest
     that would have been earned on securities lent while simultaneously seeking
     to earn interest on the investment of cash 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,
     1999, the following Funds had securities with the following market values
     on loan (amounts in thousands):

(Unaudited)

     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 for both financial
     reporting and tax purposes 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 and paid quarterly for
     the Funds except for the International Equity Index Fund and the
     Diversified International Fund which declares and pays dividends, if any,
     at least annually and the Equity Income Fund and the Balanced Fund which
     declares and pays dividends monthly. 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 expiring capital loss carryforwards,
     foreign currency transactions, and deferrals of certain losses. Permanent
     book and tax basis differences 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 from net investment income and from net realized capital
     gains sufficient to relieve it from all, or substantially all, Federal
     income taxes. Withholding taxes on foreign dividends have been paid or
     provided for in accordance with the applicable country's tax rules and
     rates.

     DEFERRED 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. Prior to June 30, 1998, costs were being
     amortized using the straight-line method over a period of five years
     beginning with the commencement of each Fund's operations. After June 30,
     1998, costs are expensed as incurred. 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.

     FINANCIAL INSTRUMENTS

     Investing in financial instruments such as options, futures, indexed
     securities and sales of forward foreign currency contracts involves risk in
     excess of the amounts reflected in the Statements 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, and changes in the value of currency relative to the U.S.
     dollar. The Funds enter into these contracts primarily as a means to hedge
     against adverse fluctuations in the value of securities held or planned to
     be purchased by the Funds.

     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.

     The following is a summary of futures outstanding as of December 31, 1999:

     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.

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, Service Class and Class S. Currently, the Trust consists of forty-nine
   active funds. The Funds are each authorized to issue Class I, Class A, Class
   B and Class C shares only. Class A shares are subject to initial sales

   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
   shares and Class C shares of each of the funds. Currently, 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. 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. Class I shares of each fund are offered without
   distribution fees. For the period ended December 31, 1999, the Distributor
   received $6,306,488 from commissions earned on sales of Class A shares and
   redemption of Class B shares and Class C shares, of which, the Distributor
   re-allowed $ 5,243,206 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.

   The Advisor, the Administrator and the Distributor voluntarily agreed to
   waive a portion of their fees. For the six months ended December 31, 1999,
   fees in the following amounts were waived (amounts in thousands):

6. 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.

   As of December 31, 1999, there were no loans outstanding under this
   agreement. During the six months ended December 31, 1999, borrowings by the
   Funds under the Agreement were as follows:

   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.

8. 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 combination. The following is a summary of dates, shares
   issued, net asset value per share issued and unrealized appreciation of

9. MARQUIS REORGANIZATION:

   The Trust entered an agreement and plan of reorganization and liquidation
   ("the Marquis Reorganization") with the Marquis Family of Funds (the "Marquis
   Funds") pursuant to which all of the assets and liabilities of each Marquis
   Fund transferred to a fund of the One Group in exchange for shares of the
   corresponding fund of the One Group. The Marquis Reorganization, which
   qualified as a tax-free exchange for Federal income tax purposes, was
   completed on August 10, 1998 following approval by shareholders of the
   Marquis Funds at a special shareholder meeting. The following is a summary of
   shares outstanding, net assets, net asset value per share issued and

10. PEGASUS REORGANIZATION:

    The Trust entered an agreement and plan of reorganization and liquidation
    ("the Pegasus Reorganization") with the Pegasus Family of Funds (the
    "Pegasus Funds") pursuant to which all of the assets and liabilities of each
    Pegasus Fund transferred to a fund of the One Group in exchange for shares
    of the corresponding Fund of the One Group. The Pegasus Reorganization,
    which qualified as a tax-free exchange for Federal income tax purposes, was
    completed on March 21, 1999 following approval by shareholders of the
    Pegasus Funds at a special shareholder meeting. The following is a summary
    of shares outstanding, net assets, net asset value per share issued and
    unrealized appreciation immediately before and after the Pegasus
    Reorganization (amounts in thousands except per share amounts):
