(b) Non-income producing securities.

(c) The Fund invests in securities whose value is derived from an underlying
    pool of mortgages or consumer loans. Descriptions of certain collateralized
    mortgage obligations are as follows:

     Inverse Floaters (IF) represent securities that pay interest at a rate that
     increases (decreases) with a decline (increase) in a specified index.

     Principal Only (PO) represents the right to receive the principal portion
     only on an underlying pool of mortgage loans. The market value of these
     securities is extremely volatile in response to changes in market interest
     rates. As a prepayments on the underlying mortgages of these securities
     increase, the yield on these securities increases.

  * The interest rate for this variable rate note, which will change
    periodically, is based on prime rates or an index of market rates. The rate
    reflected on the Schedule of Portfolio of Investments is the rate in effect
    as of June 30, 2000.

See notes to financial statements.

     Interest Only (IO) represents the right to receive the monthly interest
     payment on an underlying pool of mortgage loans. The face amount shown
     represents the par value on the underlying pool. The yields on these
     securities are generally higher than prevailing market yields on other
     mortgage-backed securities because their cash flow patterns are more
     volatile and there is a greater risk that the initial investment will not
     be fully recouped. These securities are subject to accelerated principal
     paydowns as a result of prepayment or refinancing of the underlying pool of
     mortgage instruments. As a result, interest income may be reduced
     considerably.

     High Coupon Bonds (HB) (a.k.a "IOettes") represent the right to receive
     interest payments on an underlying pool of mortgages with similar risks as
     those associated with IO securities. Unlike IOs the owner also has the
     right to receive a very small portion of principal. The high interest rate
     results from taking interest payments from other classes in the REMIC trust
     and allocating them to the small principal of the HB class.

     Principal Only (PO) represents the right to receive the principal portion
     only on an underlying pool of mortgage loans. The market value of these
     securities is extremely volatile in response to changes in market interest
     rates. As prepayments on the underlying mortgages of these securities
     increase, the yield on these securities increases.

(c) Security exempt from registration under Rule 144A of the Securities Act of
    1933. These securities may be resold in transactions exempt from
    registration, normally to qualified institutional buyers. These securities
    amounted to $483,800 or 0.5% of net assets.

 * The interest rate for this variable rate note, which will change
   periodically, is based on prime rates or an index of market rates. The rate
   reflected on the Schedule of Portfolio Investments is the rate in effect as
   of June 30, 2000.

SCHEDULE OF PORTFOLIO INVESTMENTS, CONTINUED                       JUNE 30, 2000
(Unaudited)

(b) The Fund invests in securities whose value is derived from an underlying
    pool of mortgages or consumer loans. Descriptions of certain collateralized
    mortgage obligations are as follows:

     Inverse Floaters (IF) represent securities that pay interest at a rate that
     increases (decreases) with a decline (increase) in a specified index.

     Principal Only (PO) represents the right to receive the principal portion
     only on an underlying pool of mortgage loans. The market value of these
     securities is extremely volatile in response to changes in market interest
     rates. As prepayments on the underlying mortgages of these securities
     increase, the yield on these securities increases.

 * The interest rate for this variable rate note, which will change
   periodically, is based on prime rates or an index of market rates. The rate
   reflected on the Schedule of Portfolio Investments is the rate in effect as
   of June 30, 2000.

See notes to financial statements.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 2000
(Unaudited)

1. ORGANIZATION:

   One Group Investment Trust (the "Trust") was organized as a Massachusetts
   Business Trust on June 7, 1993. The Trust is registered under the Investment
   Company Act of 1940 as an open-end management investment company. The
   accompanying financial statement and financial highlights are those of the
   Mid Cap Growth Portfolio, the Mid Cap Value Portfolio, the Diversified Mid
   Cap Portfolio, the Large Cap Growth Portfolio, the Diversified Equity
   Portfolio, the Equity Index Portfolio, the Balanced Portfolio, the Bond
   Portfolio and the Government Bond Portfolio, (individually a "Portfolio",
   collectively the "Portfolios"). Each Portfolio is a diversified mutual fund.

   SUBSTITUTION OF ONE GROUP INVESTMENT TRUST PORTFOLIOS FOR PEGASUS VARIABLE
   FUNDS

   On October 2, 1998, First Chicago NBD Corporation and BANC ONE CORPORATION
   merged with and into BANK ONE CORPORATION. At that time, the Pegasus Variable
   Funds were advised by First Chicago NBD Investment Management Company
   (FCNIMCO) and had been sold exclusively to separate accounts of Hartford Life
   and Annuity Insurance Company (Hartford) to fund variable annuity and
   variable life contracts. Hartford was granted an exemptive order from the
   Securities and Exchange Commission providing relief from certain rules in
   order to substitute shares of five of the One Group Investment Trust
   Portfolios for shares of the Pegasus Variable Funds. This substitution
   occurred March 31, 1999.

   On March 31, 1999, the shares of the following portfolios of the Trust were
   effectively substituted by Hartford for shares of the following Pegasus
   Variable Funds in separate accounts maintained by Hartford:

    Mid Cap Value Portfolio                    Intrinsic Value Fund

    Diversified Equity Portfolio               Growth and Value Fund
</TABLE>

   The financial information shown for the Bond Portfolio, the Diversified Mid
   Cap Portfolio, the Mid Cap Value Portfolio, and the Diversified Equity
   Portfolio for all periods through December 31, 1998 represents the activity
   of the Pegasus Variable Funds prior to the substitution. The financial
   information for such Portfolios for the year ended December 31, 1999
   represents the combined activity of the corresponding Pegasus Variable Funds
   for the period January 1, 1999 through March 31, 1999, and of the Portfolios
   for the period April 1, 1999 through December 31, 1999.

   Thus, with the exception of the Large Cap Growth Portfolio, the Pegasus
   Variable Funds are the survivors for accounting purposes.

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 2000
(Unaudited)

   The shares of the Portfolios are sold at net asset value to separate accounts
   of insurance companies to fund variable annuity and variable life contracts.

2. SUMMARY OF 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 U.S. 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
     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 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 the fair value as determined by the
     Pricing Committee which is comprised of members from One Group
     Administrative Services (the "Administrator"), an affiliate of Banc One
     Investment Advisors (the "Advisor") and BISYS Fund Services Ohio, Inc. (the
     "Fund Accountant") under the direction of the Board of Trustees.

     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.

     FEDERAL INCOME TAX

     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.

     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 includes premium

     amortization and discount accretion for both financial reporting and tax
     purposes. Amortization and accretion are calculated using the effective
     interest method.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income, if any, are declared and paid
     quarterly for the Funds. 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 have
     been reclassified among the components of net assets.

     EXPENSES

     Direct expenses of a Portfolio are allocated to that Portfolio. The general
     expenses of the Trust are allocated among the respective Portfolios.

     SECURITIES LENDING

     To generate additional income, the Portfolios may lend up to 33 1/3% of
     securities in which each Portfolio is invested, pursuant to agreements
     requiring that the loan be continuously secured by collateral equal at all
     times to at least 100% of the market value plus accrued interest on the
     securities lent. Collateral may include 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 such collateral. The Portfolios
     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 plus accrued interest 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
     risk. Loans are subject to termination by the Portfolios or the borrower at
     any time, and are, therefore, not considered to be illiquid investments. As
     of June 30, 2000, the following Portfolios had securities with the
     following market values on loan:

     FINANCIAL INSTRUMENTS

     Investing in financial instruments such as futures and indexed securities
     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 Portfolios 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 Portfolios 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 Portfolios.

     FUTURES CONTRACTS

     The Portfolios 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.

3. INVESTMENT ADVISORY AND ADMINISTRATION AGREEMENTS:

   The Trust and the Advisor are parties to an investment advisory agreement
   which the Advisor is entitled to a fee, computed daily and paid monthly, of

   an administration agreement under which the Administrator provides services
   for a fee that is computed daily and paid monthly, at an annual rate of 0.18%
   on the first $250 million in Trust average daily net assets (except for the
   Equity Index Portfolio) and 0.14% on Trust average daily net assets in excess
   of $250 million (except for the Equity Index Portfolio). The Administrator is
   entitled to a fee at the rate of 0.14% of the Equity Index Portfolio's
   average daily net assets.

5. DEFERRED COMPENSATION PLAN:

   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.
