Report From Your Investment Advisor
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
We are pleased to present this semiannual report for The One Group(R) Family of
Mutual Funds. On the following pages, you will find an overview of the financial
markets and your fund's performance for the period from July 1, 1997, through
December 31, 1997.
 
DEAR VALUED SHAREHOLDER:
Thank you for continuing to support The One Group Family of Mutual Funds during
an interesting, challenging and ultimately rewarding year for investors.
 
Despite strong volatility throughout 1997 and turmoil in Asia, the Dow Jones
Industrial Average was up 24.94% for 1997. Never before had the index returned
more than 20% for three consecutive years. The S&P 500 Index soared even higher,
closing the year up 33.36%.
 
At the same time, and largely the result of low inflation, a strong U.S. dollar
and the flight to quality spurred by the Asian crisis, U.S. bond yields ended
the year on an impressive note. The 30-year Treasury, for example, ended the
year yielding 5.92%, close to its 20-year low. (As bond yields fall, bond prices
go up.)
 
ONCE AGAIN, A PHILOSOPHY REINFORCED
While the calendar-year returns for both the stock and bond markets are
impressive, events in the final six months of 1997 may be the most memorable. On
August 6, the Dow closed at 8,259, a record high and its peak for the calendar
year. Shortly thereafter, though, volatility rocked the market, as the effects
of the Asian financial crisis worked their way west. These forces culminated on
Monday, October 27, when the Dow plummeted more than 554 points, its
largest-ever point decline.
 
This drop may be the defining moment for 1997's financial markets, and it
presented a significant challenge for investors. But, rather than panicking,
shareholders of The One Group demonstrated a clear understanding of market
dynamics and the importance of maintaining a long-term investment philosophy.
 
I am pleased to report that there were no significant redemptions of One Group
shares after "Black Monday." To us, this implies that our investors understand
the potential dangers of selling their investments based on short-term
volatility. In fact, The One Group experienced a record purchase day on Tuesday,
October 28, indicating that investors realize the benefits of staying focused on
the stock market's long-term potential.
 
TAX BILL CHANGES FACE OF INVESTING
The second half of 1997 may be remembered as much for the jubilance it brought
investors as for the turmoil. The Taxpayer Relief Act of 1997 became law,
ushering in lower capital gains taxes for investors and new investment
opportunities poised to change the face of investing for years to come.
 
The cut in the capital gains tax rate may make investing in stocks even more
attractive for many investors. As you are planning for your future financial
needs and taking into consideration your appropriate asset allocation, please do
not overlook the impact of the new tax treatment of capital gains.
 
And, while you're planning for your financial future, take note that the 1997
tax law makes investing in IRAs even more attractive, particularly with the
introduction of the Roth IRA, a new type of account that offers tax-exempt
distributions in retirement. In addition, the Traditional IRA has been enhanced
with many new features.
 
The One Group can help you incorporate any of these retirement accounts into
your investment plan. Speak to your investment representative or call
1-800-480-4111 for more information on IRAs.
 
SEEK ADVICE FOR A YEAR'S WORTH OF EVENTS
With 1997's record volatility and the new investment opportunities introduced by
the tax law, now may be an ideal time to meet with your investment professional
and make sure your investment plan remains on track to meet your financial
needs.
 
As you probably know, your asset allocation--or the way your investment dollars
are strategically distributed among stock, bond and cash investments according
to your goals, risk tolerance and investing time frame--may be the
single-greatest determinant of your long-term investment success. After a year
full of market ups and downs, your asset allocation probably shifted. For
example, stock market appreciation may have caused your allocation to equities
to swing higher than called for in your plan. Your investment professional can
help you evaluate your plan and, if necessary, get it back on track.

Furthermore, your investment representative can help you make the most of the
Taxpayer Relief Act of 1997. Many of the provisions take effect with the 1998
tax year, so make sure you start off the year with the strategy that's most
appropriate for you.
 
Thank you for investing with The One Group Family of Mutual Funds and for your
ongoing support of the firm's time-tested investment philosophies. We look
forward to helping you achieve your financial goals in 1998 and beyond.
 
Sincerely,

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
ECONOMIC GROWTH REMAINS STRONG
Despite showing a slight slowdown from the first half of the year, U.S. economic
growth during the second half of 1997 remained robust at a growth rate of 3.7%.
For the entire 12-month period, the U.S. economy grew by a 3.8% growth rate.
 
Firm employment gains and strong consumer confidence fueled the growth rate. The
unemployment rate headed steadily downward, ending the year at 4.7%. The economy
witnessed an average of 301,500 new non-farm jobs being created per month, when
all that is needed to absorb the growth in the labor force and keep the
unemployment rate steady is 150,000.
 
LONG-TERM INTEREST RATES DECLINE
Slightly higher inflation in 1996 kept long-term interest rates relatively high
throughout much of 1997. With prices climbing 3.3% on a year-over-year basis in
1996, investors feared that inflation would keep that pace or even climb higher
in 1997.
 
But, as the year unfolded it became apparent that inflation was, indeed, under
control. For the final six months of the year the inflation rate was 2.0%, and
for the entire year prices were up only 1.7%, the best performance in 11 years.
 
Low prices helped pave the way for a significant decline in long-term interest
rates by the end of the year. Also significant was the impact of the Asian
financial crisis, which caused currency values to plunge and sent financial
markets into turmoil. As worldwide events unfolded during the second half of the
year, it became clear that the Asian economies would weaken. This caused
investors throughout the world to turn to the safety of U.S. Treasury
securities, which helped drive up prices.
 
As a result of these events, long-term interest rates showed a significant
decline during the second half of 1997--a decline that was much greater than the
economic fundamentals supported. At the end of the year, the yield on the
30-year U.S. Treasury bond was 5.92%, after starting the year at 6.64% and
climbing to a high of 7.17% in early April.
 
FED REMAINS IDLE
The Federal Reserve remained on the sidelines during the second half of the
year, after raising interest rates just once in all of 1997--a 0.25% increase of
the federal funds rate in March. This lack of monetary policy action kept
short-term interest rates relatively steady for the remainder of the year.
 
The impact of the Asian currency crisis and market meltdowns may have
contributed to the Fed's decision to keep rates unchanged in the second half of
1997. While strong economic growth certainly created a valid reason for another
rate hike, the Fed resisted the temptation, figuring that the Asian situation
would contribute to slower growth ahead.
 
LOOKING AHEAD
In terms of U.S. economic growth, the Asian crisis remains a factor that can't
be ignored. Thirty percent of U.S. exports go to Asia, and with many Asian
countries facing currency devaluations of 35% to 80%, consumers in that region
have significantly less purchasing power. Furthermore, there's the possibility
that this currency crisis could spread to Latin America, where another 20% of
U.S. exports are at risk if there are some currency devaluations.
 
The United States accounts for 28% of the non-Asian global economy, and,
therefore, should be heavily influenced by the change in trade flows from Asia.
Asian stock markets have dropped nearly 70% over the last several months, which
undoubtedly will be reflected in lower overall consumption, particularly for
foreign imports. And, as prices on goods produced in Asia continue to fall, U.S.
imports from that region should go up.
 
As a result, cheaper goods coming from Asia, and possibly Latin America, should
force domestic competitors to lower their prices (or face sharply lower sales
prospects). This could push the U.S. inflation rate to as low as 1.5% in 1998,
compared to 1.7% in 1997 and 3.3% in 1996. At the same time, fewer U.S. exports
and greater imports should cause economic growth to slow to a 2% year-over-year
average for 1998.

THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
Given all the instability overseas and the impending effects of a slowdown in
the U.S. economy, we believe that the Federal Reserve will lower interest rates
in 1998, probably sometime in the second half of the year. Long-term interest
rates should continue their downward trend, due to lower inflation and lower
economic growth. By the end of the year, we may see the yield on the 30-year
Treasury bond somewhere between 5.5% and 5.75%.

Portfolio Performance Review

THE ONE GROUP FAMILY OF MUTUAL FUNDS                           DECEMBER 31, 1997
 
OBSTACLES EMERGE, BUT MARKET PERSEVERES
Despite facing its most formidable challenge in years--the Asian financial
crisis, which led to turmoil in equity markets worldwide--the U.S. stock market
continued to climb during the second half of 1997. For the final six months of
the year, the market, as measured by the S&P 500 Index, returned 10.58%,
bringing its total return for the 1997 calendar year to an impressive 33.36%.
 
The Dow Jones Industrial Average suffered its worst single-day point decline on
October 27, but bounced back to gain 4.01% in the second half of the year. For
the 12-month period ended December 31, 1997, the Dow was up 24.94%, marking the
first time that the index posted returns greater than 20% for three years in a
row.
 
Once again, the "Goldilocks Economy" helped fuel the market's growth. Everything
was "just right." Inflation remained lower than expected, interest rates
declined and unemployment hit record lows. This led to stronger-than-expected
economic growth and helped push corporate earnings growth to levels that were
better than anticipated.
 
We are pleased to report that The One Group domestic stock funds provided
attractive results for the six-month and one-year periods ended December 31,
1997. Returns for the U.S. Funds were particularly strong for the 12-month
period.
 
DIFFERENT STYLES SHARE THE LIMELIGHT
Overall, large-company growth stocks retained their leadership position during
1997, but their outperformance versus other equity styles was not as great as it
had been in recent years. In fact, there was significant style rotation during
the second half of the year, underscoring the importance of investing in
multiple equity styles to capture performance advantages.
 
During the summer months, for example, investors favored the stocks of small and
mid-size growth companies. In the fourth quarter, investors focused on defensive
equity strategies, and mid-size value stocks became the best relative
performers.
 
In terms of economic sectors, three offered notable performance. The technology
sector suffered severe volatility during the six-month period, due mostly to the
events in Asia. The utilities sector lagged most of the year but staged a
comeback in the fourth quarter, as investors turned to stocks that typically
provide a defensive hedge. The financial sector remained strong throughout the
entire year.
 
INTERNATIONAL MARKET HARD-HIT BY ASIAN CRISIS
The Asian currency crisis and resulting market meltdown had the greatest impact
in the international equity arena, where returns, as measured by the Europe,
Australia and Far East Gross Domestic Product (EAFE GDP) Index, fell 5.46% in
the second half of 1997. For the 12-month period, the EAFE GDP Index was up only
5.95%.
 
Much of this poor performance was due to the Japanese market, which comprises
25% of the Index, and the rest of the Far East contingent. At the same time, the
dollar's strength versus other currencies magnified the downturn in U.S.
dollars. On the bright side, though, several European countries rebounded from
recession to post strong relative performance--stronger than the S&P 500, in
some cases.
 
STOCKS SHOULD COOL FROM RECORD-BREAKING PACE
While domestic stocks should enjoy another positive year in 1998, it's unlikely
that the record-breaking pace of the last three years will continue.
 
We believe that conditions remain favorable for another year of positive
returns, but we think that the market environment will be much more volatile due
to worldwide deflationary fears and high valuation levels. It's important to
remember, though, that in 1995, 1996 and early 1997 we saw extremely low levels
of volatility. What we should see in 1998 is a return to more "normal" levels of
volatility.
 
While the economy should remain favorable for stocks, economic growth should
slow in 1998, which could cause earnings to moderate. In fact, for the first
time in several years, earnings growth will likely move from double digits to
single digits. But what may be even more important than earnings growth is
earnings reliability. Slower economic growth and the fallout from the Asian
situation will make it extremely important for companies to meet their earnings
expectations.
 
On the international front, we believe that European stocks are well positioned
for another strong year. On the other hand, economic problems in Japan and the
rest of Asia should lead to dramatically slower growth for Asia.
 
All of these factors underscore the importance of maintaining a disciplined
approach to equity investing. We encourage our investors to remain diversified
among a variety of stock types and to stay focused on long-term returns.

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 Asset Allocation Fund,
   the Income Equity Fund, the Equity Index Fund, the Value Growth Fund, the
   Large Company Value Fund, the Disciplined Value Fund, the Large Company
   Growth Fund, the Growth Opportunities Fund, the Small Capitalization Fund
   (previously named the Gulf South Growth Fund) and the International Equity
   Index Fund (individually a "Fund", collectively the "Funds") only. In 1997
   the investment objective of the Gulf South Growth Fund was changed to permit
   investments in companies headquartered or doing business outside of the
   Southeastern region of the United States, and to focus the Fund's investments
   to a greater extent on investments in the equity securities of small
   capitalization and emerging growth companies. As a result, the name of the
   Fund was changed to The One Group Small Capitalization Fund. Each Fund is a
   diversified mutual fund.
 
   The Funds' investment objectives are as follows:

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 asked 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 last offering price. 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 Fair
   Value 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.
 
       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.
 
       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.
 
       INDEXED SECURITIES
 
   The Funds may invest in indexed securities whose value is linked either
   directly or inversely to changes in foreign currencies, interest rates,
   commodities, indices or other reference instruments. Indexed securities may
   be more volatile than the referenced instrument itself, but any loss is
   limited to the amount of the original investment.
 
       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 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

       The loaned securities were fully collateralized by cash and U.S.
       Government securities as of December 31, 1997.
 
       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 as earned 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 monthly for
       the Funds except for the International Equity Index Fund which declares
       and pays dividends, if any, at least annually. 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
 
       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. Withholding taxes on foreign
       dividends have been paid or provided for in accordance with the
       applicable country's tax rules and rates.
 
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. The Trust is registered to offer forty series
   and five classes of shares: Fiduciary Class, Class A, Class B, Class C and
   Service Class. Currently, the Trust consists of thirty-three active funds.
   The Funds are each authorized to issue Fiduciary Class, Class A, Class B and
   Class C Shares. Class A Shares are subject to initial sales charges, imposed
   at the time of purchase, in accordance with the Funds' prospectus. Certain
   redemptions of Class B and Class C Shares are subject to contingent deferred
   sales charges in accordance with the Fund's prospectus. As of December 31,
   1997, there were no shareholders in Class C of the Asset Allocation Fund,
   Large Company Value Fund or the Disciplined Value Fund. 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.
   The following is a summary of transactions in Fund shares for the periods
   ended December 31, 1997 and June 30, 1997:

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 a fee, computed daily and paid
   monthly, at the annual rate of 0.74% of the average net assets of the Income
   Equity Fund, the Value Growth Fund, the Large Company Value Fund, the
   Disciplined Value Fund, the Large Company Growth Fund, the Growth
   Opportunities Fund, and the Small Capitalization Fund; 0.65% of the average
   daily net assets of the Asset Allocation Fund; 0.55% of the average daily net
   assets of the International Equity Index Fund; and 0.30% of the average daily
   net assets of the Equity Index Fund.
 
   Independence International Associates ("IIA"), an indirect subsidiary of John
   Hancock Mutual Life Insurance Company, manages the investment portfolios of
   the International Equity Index Fund subject to the supervision of the Advisor
   pursuant to a Sub-Advisory Agreement with the Advisor. For its services, IIA
   is paid a fee by the Advisor, computed daily and paid monthly, at the annual
   rate of 0.275% of average daily net assets up to $10 million, 0.225% of
   average daily net assets over $10 million up to $25 million, 0.195% of net
   assets over $25 million up to $50 million, 0.125% of the average daily net
   assets over $50 million up to $100 million and 0.060% of the average daily
   net assets over $100 million.
 
   The Trust and 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 0.20% on the first $1.5 billion of Trust net
   assets (excluding the Investor Growth Fund, the Investor Growth & Income
   Fund, the Investor Conservative Fund, and the Investor Balanced Fund (the
   "Investor Funds") and the Treasury Only Money Market Fund and the Government
   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, 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. Fiduciary Class Shares of each Fund are offered without
   distribution fees. For the six months ended December 31, 1997, the
   Distributor received $10,266,499 from commissions earned on sales of Class A
   Shares and redemptions of Class B Shares and Class C Shares, of which, the
   Distributor re-allowed $10,245,443 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.

6. FINANCIAL INSTRUMENTS:
 
   Investing in financial instruments such as options, futures, indexed
   securities and sales of forward foreign currency contracts involves risks 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.

7. CONCENTRATION OF CREDIT RISK:
 
   The International Equity Index Fund has a relatively large concentration of
   securities invested in companies domiciled in Japan. The Fund may be more
   susceptible to the political, social and economic events adversely affecting
   the Japanese companies than funds not so concentrated.

   On December 19, 1997, the net assets of certain common trust funds managed by
   the Advisor were exchanged in a tax-free conversion for shares of the
   corresponding One Group Funds. The transaction was accounted for by a method
   followed for tax purposes in a tax-free business combination. The following

   share issued and unrealized appreciation of assets acquired as of the
