                         NOTES TO FINANCIAL STATEMENTS
 
                           JUNE 30, 1998 (UNAUDITED)
- --------------------------------------------------------------------------------
 
NOTE 1 - ORGANIZATION
 
The ONE(R) GROUP(SM) 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
Trust comprises five portfolios: the Government Bond Fund, the Asset Allocation
Fund, the Growth Opportunities Fund, the Large Company Growth Fund and the
Equity Index Fund (the "Funds"). The shares of the Funds are sold only to
Nationwide Life and Annuity Insurance Company, a subsidiary of Nationwide
Insurance Company, to fund the benefits of the ONE(R) GROUP(SM) Investors 
Annuity.
 
Investment operations commenced on August 23, 1994 for the Government Bond and
the Large Company Growth Funds, September 29, 1994 for the Asset Allocation
Fund, November 3, 1994 for the Growth Opportunities Fund and May 1, 1998 for the
Equity Index Fund.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Organization costs incurred in connection with the organization and initial
registration of the Trust were paid by the Administrator and have been
reimbursed by the Funds. Such organization costs have been deferred and are
being amortized ratably over a period of sixty months from the commencement of
operations. If any of the initial shares are redeemed before the end of the
amortization period, the proceeds of the redemption will be reduced by the
pro-rata share of the unamortized organization costs.
 
SECURITY VALUATION
 
Securities traded on a national securities exchange are valued at the last
quoted sale price on the principal exchange, or if no sale, at their fair value
as determined in good faith under consistently applied procedures authorized by
the Board of Trustees. Securities traded only in the over-the-counter (OTC)
market are valued at the last quoted sale price, or if there is no sale, at the
quoted bid price provided by an independent pricing agent. Corporate debt
securities and debt securities of U.S. issuers, including municipal securities,
are valued by a combination of daily quotes and matrix evaluations provided by
dealers or by an independent pricing service approved by the Board of Trustees.
Inactive or bonds that have little or no trading activity are evaluated by the
independent pricing services through obtaining dealer quotes. Futures contracts
and options thereon traded on a commodities exchange or board of trade are
valued at the last sales price at the close of trading, or if there was no sale,
the quoted bid price at the close of trading. Securities for which reliable
market quotations are not readily available or for which the pricing agent does
not provide a valuation that in the judgement of the Fund's investment adviser,
does not represent fair value, shall each be valued in accordance with
procedures authorized by the Board of Trustees.
 
The Funds may invest in repurchase agreements with institutions that the
investment advisor has determined are creditworthy. Each repurchase agreement is
recorded at cost. The Funds require that the securities purchased in a
repurchase agreement transaction be transferred to the custodian in a manner
sufficient to enable the Funds 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 Investment Company Act of 1940 as amended.

- --------------------------------------------------------------------------------
 
FEDERAL INCOME TAX
 
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 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 INVESTMENT INCOME
 
Security transactions are recorded on the trade date. Net realized gains or
losses from sales of securities are determined on the specific identification
method. Dividend income is recorded on the ex-dividend date; interest income is
recorded on an accrual basis and includes, where applicable, the pro-rata
amortization of premium or accretion of discount.
 
DIVIDENDS TO SHAREHOLDERS
 
Dividends are recorded on the ex-dividend date. The Funds declare and pay income
dividends quarterly. Distributable net realized capital gains are declared and
distributed at least annually. Dividends and distributions to shareholders are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax' differences are
considered either permanent or temporary in nature. To the extent that these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their nature for federal income tax purposes;
temporary differences do not require reclassification. Dividends and
distributions that exceed net investment income and net realized gains for
financial reporting purposes but not for tax purposes are reported as dividends
in excess of net investment income and net realized gains. To the extent
distributions exceed current and accumulated earnings and profits for Federal
income tax purposes, they are reported as distributions of paid-in-capital.
 
Accordingly, as of December 31, 1997, the capital accounts have been adjusted by
the following amounts:

</TABLE>
 
EXPENSES
 
Direct expenses of a Fund are allocated to that Fund. The general expenses of
the Trust are allocated to the Funds based on the relative net assets of the
Funds at the time the expense is incurred.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

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 dividends and 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 judgement 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 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 market values on loan (amounts in thousands):

The Asset Allocation Fund is engaged in trading financial futures contracts. The
Fund is exposed to market risks in excess of the amounts recognized in the
statement of assets and liabilities as a result of changes in the value of the
underlying financial instruments. Investments in financial futures require the
fund to "mark to market" such futures on a daily basis, to reflect the change in
the market value of the contract at the close of each day's trading. Typically,
variation margin payments are made or received to reflect daily unrealized gains
or losses. When the contracts are closed, the fund recognizes a realized gain or
loss. Realized gains and losses have been computed on the specific
identification method.
 
A stock index futures contract is a bilateral agreement pursuant to which two
parties agree to take or make delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the close of
trading of the contracts and the price at which the futures contract was
originally struck. The Funds' purpose in entering into futures contracts is to
remain fully invested and reduce transaction costs.
