Portfolio Performance Review

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
For the year ended June 30, 1998, The One Group Asset Allocation Fund Fiduciary
share class posted a total return of 22.12%. (For information on other share
classes and performance comparisons to indexes, please see page 4.)
 
WHAT WERE YOUR OVERALL STRATEGIES AND TACTICS?
In November 1997, we increased the Fund's equity weighting by 2%, bringing the
asset allocation to 57% equities and 43% fixed income. Our research indicated
that while stock valuations remained fairly high, corporate profitability was
strong, which prompted the slight shift toward equities. Nonetheless, the
allocation remains fairly conservative compared to our benchmark of 60% equities
and 40% fixed income.
 
The 1997 tax law created three categories of capital gains: short-term, for
securities held less than a year and taxed as regular income; mid-term, for
securities held from one year to 18 months and taxed at 28%; and long-term for
securities held for at least 18 months and taxed at 20%. To limit the number of
short-term gains, we held securities longer, reducing the Fund's turnover rate
from an average of 81% to 46% during the year.
 
HOW DID EVENTS PLAY OUT IN THE FUND'S EQUITY PORTFOLIO?
Overall, corporate earnings exceeded expectations throughout the year,
contributing to the stock market's strong performance. At the same time, a
favorable interest rate environment helped support additional gains in the
market.
 
The equity philosophy of the Fund is research driven. Our bottom-up stock
selection approach led to attractive results in the Fund's equity portfolio.
Instead of trying to time the market or focus on certain areas of the market, we
rely on fundamental research to select individual stocks from all market
sectors. As a result, the Fund's stock portfolio represents the "best ideas" of
the equity research team. Equity returns were driven by stock selection, not
market timing or sector rotation.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
During the fiscal year, the Fund's equity portfolio benefited from particularly
good stock selection in the following sectors: technology (Dell Computer, up
216%); retail (Wal-Mart, up 80%); health care (Warner-Lambert, up 68%); and
telephone utilities (LCI International, up 65%).
 
HOW DID THE PORTFOLIO'S TOP 10 HOLDINGS CHANGE?*
Six of fiscal 1997's top 10 holdings remained among the top 10 during the past
year: Microsoft, 1.9% (technology), General Electric, 1.6% (capital goods),
Exxon, 1.2% (energy) Wal-Mart, 1.0%, Bristol-Myers Squibb, 1.0% (health care)
and Intel, 1.0% (technology). The remaining top 10 stock holdings included
Nations-Bank, 1.0% (financial services), Cisco Systems, 1.0% (technology), Dell
Computer, 1.0% and Travelers Group, 0.8% (financial services).
 
HOW DID EVENTS PLAY OUT IN THE FUND'S FIXED INCOME PORTFOLIO?
The largest contributing factor to the Fund's fixed income portfolio was the
general decline in interest rates, which led to a corresponding increase in bond
prices. Events in Asia contributed to a weakening global economy, which in turn
contributed to a general decrease in U.S. bond market yields and an increase in
U.S. bond prices.
 
We maintained diversity among government, agency mortgage-backed, asset-backed
and corporate securities. With only a moderate level of volatility in the bond
market, the performance of certain mortgage-backed securities was strong. These
bonds offered yield advantages over other securities, with little offset due to
market volatility. We also purchased select corporate securities that enhanced
the portfolio's yield.
 
The portfolio's duration, at 4.3 years, remained slightly longer than our
neutral stance of 4.1 years. (Duration is a measure of a fund's price
sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) Slightly extending the duration
enabled the portfolio to experience more price appreciation resulting from the
declining interest rate environment.
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
We plan to maintain the Fund's current asset allocation mix and investment
strategies, as we expect the U.S. economy to maintain its steady, albeit slower,
growth pattern over the next year. Of course, we will continue to monitor
valuation levels in the financial markets and

watch for signs of inflationary pressures. Any changes may warrant a shift in
our strategies.
 
With slower anticipated growth, inflation is likely to remain tame and interest
rates stable. Such an environment would not threaten the Fund's investments in
corporate bonds, which would become more vulnerable in a recession, or mortgage
securities, which would suffer if interest rates were to change dramatically. In
fact, we expect mortgage-backed, asset-backed and corporate securities to offer
return advantages over Treasuries in the coming months.
 
In the stock market, we expect corporate earnings to come under greater pressure
in the months ahead. As such, we look for more "normal" performance from the
stock market. We plan to maintain our sector neutrality, which gives us the
opportunity to take advantage of opportunities in various industries and
companies.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The performance of the Asset Allocation Fund is measured against the S&P 500
Index, an unmanaged index generally representative of the performance of large
companies in the US stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management. By contrast, the performance of the fund
reflects the deduction of these value-added services as well as the deduction of
sales charges on Class A Shares and applicable contingent deferred sales charges
on Class B Shares.
 
The S&P/Lipper Mix for all the classes is a blended index consisting of 60% of
the average monthly returns of the S&P 1500 Index from January 1, 1995 (index
inception date) until present and of the S&P 500 Index from April 1993 through
December 1994. The final 40% consists of the Lipper Intermediate US Government
Bond Funds Index.

                        The One Group Income Equity Fund
Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The One Group Income Equity Fund Fiduciary share class posted a total return of
23.18% for the year ended June 30, 1998. (For information on other share classes
and performance comparisons to the Fund's benchmark index, please see page 7.)
 
With inflation, unemployment and federal fiscal balances at their best levels in
a generation, the equity market offered strong double-digit returns for the
fourth consecutive year.
 
TO WHAT DO YOU ATTRIBUTE SUCH STRONG PERFORMANCE?
The Fund continued to benefit from its concentration in the types of companies
investors have preferred-large-capitalization, high-quality, consistent-growth
companies. At the same time, the Fund was rewarded for not owning companies with
severe earnings problems, such as those with significant exposure to Asia.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our portfolio strategies during the year focused on maintaining strong
performance measures while positioning the portfolio for a more challenging
market environment we think may be in store. As such, we sold and took profits
on certain issues that have been the best performers over the last several
years. We also eliminated some disappointing holdings and established new
positions in securities that we think are likely to be future market leaders.
 
We also have been improving the Fund's current income by reducing
lower-dividend-yielding issues and building positions in higher-yielding
securities. We also cut in half the Fund's position in convertible securities
and used the proceeds to invest in real estate investment trusts (REITs). In
addition to enhancing the Fund's diversification, we believe the REITs offer
good value and add important defensive characteristics to the Fund due to their
attractive yields.
 
On average, the Fund held 89% of its assets in common stocks, 5% in convertible
securities, 5% in REITs and 1% in cash during the year.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund enjoyed strong fiscal-year performance from several sectors in which
certain companies consistently achieved superior earnings growth or benefited
from major restructuring:
 
- - Health care (Schering-Plough, Pfizer and Warner-Lambert were up 65% or more)
 
- - Finance (American Express, Chase Manhattan, U.S. Bancorp, Lincoln National,
  FNMA and National City were up 35% or more)
 
- - Telephone utilities (AT&T, BellSouth and Sprint were up 30% or more)
 
- - Selected industrials (Ford was up 55%).
 
WERE THERE ANY DISAPPOINTING HOLDINGS?*
Disappointing performers were concentrated in more volatile sectors, including
transportation (Union Pacific declined 37% for the fiscal year), energy and
mining (Amoco was off 4%, Cyprus-Amax down 46%) and manufacturing (Corning,
Boeing and Deere declined in price). Our policy in handling such "problem"
issues is to reduce the position size when earnings expectations are not being
met and sell out completely if a turnaround is unlikely, as we did with Union
Pacific and Cyprus-Amax. To help avoid problem situations, we concentrate on
favorable growth areas and look to fundamental research conducted by our
in-house analysts.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
Two new issues moved into the top 10 holdings-American Home Products, 2.1%

WHAT IS YOUR OUTLOOK FOR THE FUND?
We are pleased with the current composition of the portfolio and the fundamental
progress of the companies the Fund owns. Nevertheless, the financial markets
have been highly volatile. Many of the uncertainties confronting investors
today-Asian problems, nuclear proliferation, historically high stock
valuations-have no quick-fix solutions. Furthermore, corporate earnings gains
aren't as good as they have been in recent years. This would suggest that we
should lower our return expectations and become more focused and selective.
 
Perhaps the best plan is to remain flexible and vigilant in order to take
advantage of opportunities when they arise. If a more challenging market
develops, we believe the Fund is well positioned, given its defensive
characteristics, higher-than-average income, holdings in predictable growth
companies and exposure to real estate.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The performance of the Income Equity Fund is measured against the S&P 500 Index,
an unmanaged index generally representative of the performance of large
companies in the US stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management. By contrast, the performance of the fund
reflects the deduction of these value-added services as well as the deduction of
sales charges on Class A Shares and applicable contingent deferred sales charges
on Class B and Class C Shares.

                        The One Group Equity Index Fund
Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
For the year ended June 30, 1998, The One Group Equity Index Fund Fiduciary
share class posted a total return of 29.73%. (For information on other share
classes and a performance comparison to the index, please see page 9.)
 
As it is designed to do, the Fund offered a return that nearly matched that of
the S&P 500 Index, the unmanaged group of stocks the Fund seeks to track with
little or no excess risk. The S&P 500 Index returned 30.16% for the year. The
slight difference in returns between the Fund and the Index is due to fees and
transaction costs charged to the Fund but not to the Index.
 
WHAT CONTRIBUTED TO SUCH A STRONG RETURN?
A strong economy, low inflation, declining interest rates and favorable
corporate earnings growth led to attractive stock market returns for yet another
year. Once again, large-capitalization growth companies, the type represented in
the S&P 500 Index, outperformed other types of U.S. stocks.
 
WHICH MARKET SECTORS OFFERED NOTABLE PERFORMANCE?
The Fund offered exposure to 15 market sectors. Among those sectors, retail and
telephone utilities offered the strongest performance. The retail sector
benefited from lower costs on Asian imports, while telephone utilities advanced
due to acquisition activity.
 
The weakest-performing sectors included technology, energy and industrial
commodities. The technology sector suffered somewhat from the economic and
market crisis that swept through Asia, while energy stocks declined due to lower
oil prices. In the industrial commodities sector (chemical, paper and metal
companies), stocks suffered from the sector's lack of pricing power.
 
WHAT WERE SOME OF THE STRONGEST AND WEAKEST STOCKS?*
The Fund enjoyed outstanding performance from a handful of stocks, including
technology provider Unisys, up 270% for the fiscal year due to strong earnings;
computer manufacturer Dell Computer, up 216% on strong earnings; cable
television company Tele-Communications, up 159% and acquired by AT&T; financial
service provider Providian Financial, up 145% on strong earnings; and auto
manufacturer Ford Motor, up 55% due to strong earnings.
 
Weak earnings contributed to poor performance from certain holdings, including
diversified mining company Freeport-McMoran Copper and Gold, down 51% for the
fiscal year; technology company Advanced Micro Devices, down 52%; and technology
provider Cabletron Systems, down 53%.
 
WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
Most of the Fund's top 10 holdings retained their spots during the past year.
The only changes to the group were the addition of Pfizer, 1.5% (health care
sector) and Wal-Mart, 1.5% (retail), which replaced Philip Morris (consumer
non-durables) and IBM (technology). The remaining top 10 included General
Electric, 3.2% (capital goods), Microsoft, 2.9% (technology), Coca-Cola, 2.3%
(consumer non-durables), Exxon, 1.9% (energy), Merck, 1.7% (health care), Intel,
1.4% (technology), Proctor & Gamble, 1.3% (consumer non-durables) and Royal
Dutch Petroleum, 1.3% (energy).
 
WHAT IS YOUR OUTLOOK FOR THE STOCK MARKET?
The environment for stocks should remain favorable over the coming year. We
expect economic growth to continue, but at a slower pace. We also expect
interest rates and inflation to remain low. Corporate earnings and stock prices
should continue to grow, but earnings are likely to come under increasing
pressure. Nevertheless, it's important to remember that returns of the last few
years have been unusually strong, and they probably are not sustainable. We
expect to see stock returns revert to more "normal" levels.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The performance of the Equity Index Fund is measured against the S&P 500 Index,
an unmanaged index generally representative of the performance of large
companies in the US stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management. By contrast, the performance of the fund
reflects the deduction of these value-added services as well as the deduction of
sales charges on Class A Shares and applicable contingent deferred sales charges
on Class B and Class C Shares.

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The One Group Value Growth Fund Fiduciary share class posted a total return of
32.26% for the year ended June 30, 1998. (For information on other share classes
and performance comparisons to indexes, please see page 12.)
 
TO WHAT DO YOU ATTRIBUTE THE FUND'S SOLID RETURN?
Domestic stocks of all styles enjoyed another strong year, as low inflation,
declining interest rates and better-than-expected corporate earnings contributed
to the gains.
 
Rather than emphasizing particular market sectors or trying to time the market's
next moves, we research, evaluate and select stocks on an individual basis to
build a diversified portfolio. We don't consciously overweight a single sector
or a single style of stock. Instead, we invest in stocks from the four major
equity styles -- large capitalization growth, large capitalization value, medium
capitalization growth and medium capitalization value -- and look for stocks
that we believe offer the best return potential relative to their level of risk.
 
Over the past year, for example, we saw some vicious swings among sectors,
creating a momentum market that saw investors attempting to pick the "right"
sector at the right time. But, our emphasis on individual stock selection paid
off, as that process gave the Fund exposure to many different industries and
contributed to the Fund's strong return.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
The Fund owned more stocks than usual and was more diverse than usual in an
active attempt to be less exposed to any single momentum play. Momentum markets
tend to last longer than investors expect, and stocks that are not participating
tend to lose their value quickly.
 
Events in Asia played an interesting role in the Fund's performance. After the
domino effect, which started in Thailand, hit U.S. shores in October 1997, we
avoided the stocks of companies that we thought would be most negatively
affected by the malaise -- namely, commodity cyclical companies. By steering
away from that group, the Fund became more growth-oriented than usual.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
Industry positions such as the pharmaceutical area of health care
(Schering-Plough, up 91% for the fiscal year, and Bristol-Myers Squibb, up 42%);
the software and PC areas of technology (Microsoft, up 71%; BMC Software, up
88%; Dell Computer, up 216%); and the long distance segment of
telecommunications (Century Telephone, up 104%; Sprint, up 35%) added to the
Fund's strong performance.
 
The Fund also benefited from strong performance from Cisco Systems (technology),
up 106% for the year; Equitable Co. (financial services), up 125%; Morgan
Stanley Dean Witter (financial services), up 112%; Lucent Technologies
(technology), up 131%; and Energy East (utility), up 99%.
 
At the same time, a few Fund holdings realized poor performance, namely Callaway
Golf (consumer services), down 45% for the year; Toys R Us (retail), down 33%;
BetzDearborn (raw materials), down 37%; Columbia/HCA Healthcare (health care),
down 26%; and Phycor (health care), down 52%.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
More than half of the Fund's top 10 holdings were among the leading holdings one
year ago: Microsoft, 3.3% (technology), General Electric, 2.9% (capital goods),
Exxon, 2.1% (energy), Wal-Mart, 1.8% (retail), Bristol Myers, 1.8% (health care)
and Intel, 1.7% (technology). The remaining members of the top 10 on June 30,
1998, included NationsBank, 1.8% (financial services), Cisco Systems, 1.8%, Dell
Computer, 1.7% and Coca-Cola, 1.5% (consumer non-durables).

WHAT IS YOUR OUTLOOK FOR THE FUND?
We anticipate corporate earnings to revert to more normal levels, and we believe
volatility will continue. We plan to maintain the Fund's style diversity in
similar proportion as last year to address this market.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The above-quoted performance data includes the performance of the Paragon Value
Equity Income Fund for the period prior to the commencement of operations of The
One Group Value Growth Fund on March 26, 1996. Performance for the Fiduciary
Shares is based on Class A Share performance adjusted to reflect the absence of
sales charges.
 
The performance of the Value Growth Fund is measured against the S&P 1500 Index,
an unmanaged index generally representative of the performance of large and
small companies in the US stock market. Investors are unable to purchase the
index directly, although they can invest in the underlying securities. The
performance of the index does not reflect the deduction of expenses associated
with a mutual fund, such as investment management. By contrast, the performance
of the fund reflects the deduction of these value-added services as well as the
deduction of sales charges on Class A Shares and applicable contingent deferred
sales charges on Class B and Class C Shares.
 
The S&P 1500 Index for all classes consists of the average monthly returns of
the S&P 500 Index from December 1989 through December 1994. Thereafter, the data
are from the S&P 1500 Index which corresponds with the initiation of the S&P
1500 Index on January 1, 1995.

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
For the year ended June 30, 1998, The One Group Large Company Value Fund
Fiduciary share class posted a total return of 21.46%. (For information on other
share classes and a performance comparison to the index, please see page 15.)
 
TO WHAT DO YOU ATTRIBUTE THE FUND'S SOLID RETURN?
A positive economic environment led to strong corporate earnings growth, which
benefited stocks in the Fund. Likewise, low inflation and a favorable interest
rate environment boosted stock values.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our strategy involves implementing traditional value-investing techniques,
including focusing on stocks with below-average price-to-earnings and
price-to-book ratios. We employ this approach within the context of our basic
research discipline -- investing in attractively priced stocks with improving
fundamentals. Our goal is to realize price appreciation within a reasonable time
horizon.
 
We slightly modified the Fund's sector weightings during the year, increasing
exposure to electric utilities so that the sector is now a bit overweighted. We
believe the industry is well into its deregulation cycle, and we expect returns
to become even more compelling. This should result in further buying interest
going forward. We also made some minor changes in the technology sector, where
computer giant IBM is now the sector's largest holding.
 
DID EVENTS OVERSEAS INFLUENCE FUND RETURNS?
While the companies in which the Fund invests do not have tremendous exposure to
Europe, the stronger economies in that region did have an overall positive
impact on the Fund. On the other hand, weak Asian demand hurt companies with
significant Asian sales, especially in the capital goods sector. Fortunately,
the Fund was only slightly affected, as just 5% of its holdings had exposure to
Asia.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund was invested primarily in energy, banking, financial and telephone
stocks during the year. The banking and financial stocks were the best
performers due to continued consolidation in their industries. In fact, the Fund
enjoyed fiscal-year gains of at least 20% from the following financial services
companies: Travelers Group, Morgan Stanley Dean Witter, Lincoln National,
Hartford Financial Services Group and Fannie Mae.
 
Acquisition targets also proved to be among the best performing Fund holdings.
Auto maker Chrysler saw its stock price advance 71% over the year, primarily due
to its merger with German car maker Daimler Benz. In the telephone industry, MCI
Communications' pending acquisition by WorldCom pushed shares of MCI 52% higher
for the year. And, in the raw materials sector, Alcoa's acquisition of Alumax
helped shares of Alumax advance 22%.
 
On the other hand, energy stocks lagged as weak oil prices hurt earnings.
Because of this, we decreased the Fund's exposure to the major oil companies and
increased exposure to the natural gas pipeline and refining companies. The
refining companies are expected to benefit from lower oil prices.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
More than half of the Fund's top 10 holdings remained unchanged during the year.
Those that held their spots from the previous year included Exxon, 4.3%
(energy), IBM, 4.2%, NationsBank, 2.8% (financial services), Travelers Group,
2.8%, Royal Dutch Petroleum, 2.7% (energy) and BankAmerica, 2.1% (financial
services). New to the group were Chrysler, 2.1%, Allstate, 1.9% (financial
services), Sears Roebuck & Co., 1.9% (retail) and Citicorp, 1.8% (financial
services).

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Our outlook for the economy suggests a favorable environment for stocks over the
coming year. We expect modest, but slower, economic growth with interest rates
and inflation remaining under control. As such, we expect corporate earnings and
stock prices to continue to grow. But, we expect to see stock returns revert to
more "normal" levels, compared to the unusually high results of the past few
years.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The performance of the Large Company Value Fund is measured against the
S&P/BARRA 500 Value Index, an unmanaged index representing the performance of
the lowest price to book securities in the S&P 500. Investors are unable to
purchase the index directly, although they can invest in the underlying
securities. The performance of the index does not reflect the deduction of
expenses associated with a mutual fund, such as investment management. By
contrast, the performance of the fund reflects the deduction of these
value-added services as well as the deduction of sales charges on Class A Shares
and applicable contingent deferred sales charges on Class B Shares.

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The One Group Disciplined Value Fund Fiduciary share class posted a total return
of 28.27% for the year ended June 30, 1998. (For information on other share
classes and performance comparisons to the index, please see page 18.)
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Interest rates ended the year lower, but experienced volatility throughout the
12-month period. To avoid some of the stock price volatility associated with
interest rate swings, we maintained a diversified portfolio with exposure to a
variety of economic sectors. Within this framework, we emphasized in-depth
analysis and individual stock selection, and we continued to rebalance the
portfolio in order to improve structure and upgrade holdings as market
conditions changed.
 
Because of the Fund's value orientation, we emphasized the sectors that offered
the greatest perceived value. As a result, almost half of the Fund's assets were
in the electric utility, financial, industrial, commodity and banking sectors.
These were the areas that contained the largest number of equity securities with
below-market-average price-to-earnings and price-to-book ratios.
 
Given the continued strength of the market, certain stocks reached their target
prices quicker than we had anticipated, prompting the sale of those securities
and the purchase of new ones. In addition, as certain stocks increased in
valuation, they became more growth-like and were no longer appropriate for this
value-oriented fund. For example, in the second half of 1997 prices on bank
stocks soared, and the resulting valuations converted many of these stocks to
growth stocks. As a result, remaining sectors that were relatively undervalued
became more influential, and their weightings within the Fund increased.
Specifically, we increased the Fund's holdings within the capital equipment,
financial, industrial commodity and consumer durable sectors to make up for the
gap caused by the decline in bank holdings.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
Outstanding performance from several individual stocks during the fiscal year
was driven largely by takeovers. For example, in the technology sector Qwest
Communications acquired LCI International, in which the Fund had a large
exposure; National City Bank acquired First of America, a Fund holding; and
Williams Companies acquired the energy company Mapco, another Fund holding. In
addition, the Fund's holding of Century Telephone nearly doubled in value over
the year, as analysts projected superior earnings growth for the combined
Century Telephone/Pacific Telesis company. Indeed, the merged company
experienced revenue growth and margin expansion after joining forces, as it cut
costs and expanded its territory.
 
Another merger, between cement manufacturers Southdown and Medusa, also
contributed to the Fund's solid return. But, price gains on these stocks
primarily were driven by excellent fundamentals within the industry. The
supply/demand equation favored the manufacturers, given the steadily increasing
demand for cement from the housing and infrastructure sectors, while the supply
of cement has been virtually unchanged in the last decade. In addition, U.S.
government restrictions on the amount of cement that can be imported helped the
U.S. manufacturers.
 
DID EVENTS IN ASIA INFLUENCE ANY OF THE FUND'S HOLDINGS?*
On the downside, events in Asia caused certain Fund holdings to decline. As
Asian currency values plummeted, it appears Asian customers chose to curtail
their gaming excursions to the United States. As a result, the Fund's holdings
in Circus Circus and MGM declined for the fiscal year. In addition, CompUSA lost
half of its value due to the unanticipated sharp declines in computer prices.
Lower demand from Asia contributed to the price declines, as did the lack of new
memory-consuming software applications, which prompted revenue declines and
margin contraction.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE DURING THE FISCAL YEAR?*
Only two of the Fund's top 10 holdings remained from last year -- CMS Energy,
1.6% (utilities) and Southtrust Corp., 1.6% (financial services). Rounding out
the top 10 were utilities companies New Century Enterprises, 1.5%, Allegheny
Energy, 1.3%, Century Telephone, 1.5%, El Paso Natural Gas, 1.6% and Teco
Energy, 1.2%; financial companies Bear Stearns,

1.6% and Paine Webber, 1.2%; and Tyson Foods, 1.1%, a member of the consumer
non-durable sector.
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Looking ahead, we plan to maintain our current strategy of broad sector
diversification, stringent in-house research and individual stock selection.
Within each sector, we will continue to look for the best values among medium
capitalization stocks, or those issues with low price/earnings and price/book
ratios.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The performance of the Disciplined Value Fund is measured against the S&P/BARRA
Midcap 400 Value Index, an unmanaged index representing the performance of the
lowest price to book securities in the S&P Midcap 400 Index. Investors are
unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management. By contrast, the performance of the fund reflects the deduction of
these value-added services as well as the deduction of sales charges on Class A
Shares and applicable contingent deferred sales charges on Class B Shares.
 
The S&P/BARRA Midcap 400 Value Index consists of the average monthly returns of
the S&P 500 Index for periods prior to June 1991. Thereafter, the data are from
the S&P/BARRA Midcap 400 Value Index which corresponds with the initiation of
the S&P/BARRA Midcap 400 Value Index on June 30, 1991.

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The One Group Large Company Growth Fund Fiduciary share class posted a total
return of 35.75% for the year ended June 30, 1998. (For information on other
share classes and performance comparisons to indexes, please see page 20.)
 
TO WHAT DO YOU ATTRIBUTE THE FUND'S SOLID RETURN?
A strong domestic economy, low inflation and declining interest rates all worked
together to maintain a favorable equity environment. Once again, the market
favored the largest growth-oriented companies because of their earnings
reliability and stock liquidity.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary investment strategy during this market climate has been to find good
companies within industries that are growing at a faster rate than the economy.
These are companies that we believe have the ability to exhibit sustained growth
at some multiple of their underlying industry growth rate. In addition, we
search for strong management teams and superior product positioning.
 
After evaluating the impact of the Asian crisis on the Fund's stocks, we cut the
portfolio's technology holdings because much of these companies' exports went to
Asia. We also increased our retail holdings, as many of these companies purchase
their materials from Asia and thus benefit from lower costs.
 
This strategy worked well, because the technology sector, as a whole, has
underperformed the market, while the retail sector has outperformed.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund enjoyed outstanding performance from computer manufacturer Dell
Computer, up 216% for the fiscal year; software giant Microsoft, up 71% and
online service provider America Online, up 278%.
 
On the other hand, there were a few disappointing performances from the
technology sector. For example, Applied Materials was off 17% and Oracle Corp.
declined 27%.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
Most of the Fund's top 10 holdings remained unchanged during the year. The only
newcomers were Dell Computer, 2.6% (technology) and Lucent Technologies, 2.3%
(technology). The remaining members included General Electric, 6.8% (capital
goods), Microsoft, 6.4% (technology), Coca-Cola, 4.3% (consumer non-durable),
Wal-Mart, 3.2% (retail), Merck, 3.0% (health care), Bristol-Myers Squibb, 3.0%
(health care), Pfizer, 2.9% (health care) and Proctor & Gamble, 2.6% (consumer
non-durable).
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Looking ahead, we remain optimistic about continued U.S. economic growth and low
inflation. We believe that interest rates may continue to decline, which would
support ongoing stock market growth, but perhaps not at the unusually strong
pace we've seen over the last several years. As such, it seems prudent to lower
our expectations somewhat for the next year.
 
Our overall strategy remains intact -- to search for companies with strong
fundamentals, effective management teams and favorable long-term outlooks.
Because the Asian situation remains unresolved, we will continue to monitor its
effects on the Fund's holdings.

S&P/BARRA 500 Growth Index, an unmanaged index representing the performance of
the highest price to book securities in the S&P 500. Investors are unable to
purchase the index directly, although they can invest in the underlying
securities. The performance of the index does not reflect the deduction of
expenses associated with a mutual fund, such as investment management. By
contrast, the performance of the fund reflects the deduction of these
value-added services as well as the deduction of sales charges on Class A Shares
and applicable contingent deferred sales charges on Class B and Class C Shares.

                    The One Group Growth Opportunities Fund
Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
The One Group Growth Opportunities Fund Fiduciary share class posted a total
return of 31.11% for the year ended June 30, 1998. (For information on other
share classes and performance comparisons to indexes, please see page 22.)
 
TO WHAT DO YOU ATTRIBUTE THE FUND'S SOLID RETURN?
Medium-capitalization growth stocks continued to benefit from a strong economy,
solid corporate earnings, low inflation and low interest rates. In addition to
these factors, the Fund's performance has benefited from good stock selection.
Instead of looking for stocks based on general economic or market trends, we
evaluate stocks on an individual basis, searching for those with appealing
fundamentals.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary investment strategy is to identify high growth companies within
attractive, fast-growing industries. We look for companies that will benefit
from strong management teams and competitive advantages. These factors should
allow sustained high growth at a rate that outpaces the industry average.
 
After the Asian crisis erupted, we evaluated the impact of the fallout. Many of
the Fund's technology companies had significant Asian exports, so we cut certain
technology holdings to lessen the impact that decreased Asian demand would have
on these companies. At the same time, we increased our retail holdings because
many of these companies purchase materials from Asia. As such, these retailers
were able to benefit from lower prices on Asian imports.
 
This strategy worked well, because the technology sector, as a whole,
underperformed the market, while the retail sector outperformed.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund enjoyed outstanding performance from computer manufacturer Dell
Computer, up 216% for the fiscal year; retailer Just for Feet, up 63% and
technology company Compuware, up 114%.
 
On the other hand, there were a few disappointing performances from Altera
(technology), down 42% for the fiscal year; KLA-Tencor (technology), down 43%;
and Global Marine (energy), down 19%.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
Half of the Fund's top 10 holdings changed during the year. At year-end, those
that remained in the top 10 included Coca-Cola Enterprises, 3.0% (consumer non-
durable), BMC Software, 2.2% (technology), Just for Feet, 2.0% (retail), AES
Corp., 1.9% (utilities) and AFLAC, 1.6% (financial services). The new members
included America Online, 4.4% (technology), USA Waste Services, 2.5% (capital
equipment), Compuware, 2.0% (technology), Kohl's, 1.6% (retail) and Staples,
1.6% (retail).
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Looking ahead, we remain optimistic about continued U.S. economic growth and low
inflation. We believe that interest rates may continue to decline, which would
support ongoing stock market growth, but perhaps not at the unusually strong
pace we've seen over the last several years. As such, it seems prudent to lower
our expectations somewhat for the next year.
 
Our overall strategy remains intact -- to search for companies with strong
fundamentals, effective management teams and favorable long-term growth rates.
Because the Asian situation remains unresolved, we will continue to monitor its
effects on the Fund's holdings.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The performance of the Growth Opportunities Fund is measured against the
S&P/BARRA Midcap 400 Growth Index, an unmanaged index representing the
performance of the highest price to book securities in the S&P Midcap 400 Index.
Investors are unable to purchase the index directly, although they can invest in
the underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management. By contrast, the performance of the fund reflects the deduction of
these value-added services as well as the deduction of sales charges on Class A
Shares and applicable contingent deferred sales charges on Class B and Class C
Shares.
 
The S&P/BARRA Midcap 400 Growth Index for the Fiduciary Class Shares consists of
the average monthly returns of the Russell 2000 Index for periods prior to June,
1991. Thereafter, the data are from the S&P/BARRA Midcap 400 Growth Index which
corresponds with the initiation of the S&P/BARRA Midcap 400 Growth Index on June

                    The One Group Small Capitalization Fund
Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
For the year ended June 30, 1998, The One Group Small Capitalization Fund
Fiduciary share class posted a total return of 23.58%. (For information on other
share classes and a performance comparison to the index, please see page 24.)
 
For the fourth year in a row, performance of small-capitalization stocks trailed
that of large-capitalization stocks. Investors continued to favor larger-company
stocks because of their liquidity traits and earnings predictability.
 
WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary strategies during the year were to maintain an average market
capitalization of $500 million or less and enhance the portfolio's
diversification. We started improving the Fund's diversification in November
1997, after shareholders approved a change in the Fund's investment objective.
Previously, the Fund focused on companies based in the Southeast region of the
United States. Now, the Fund invests primarily in small and emerging companies
throughout the United States, seeking to offer growth opportunities from a much
larger universe of companies. The number of companies represented in the
portfolio increased by 40% during the year.
 
We select stocks on an individual basis, relying on in-depth research to uncover
companies with talented management teams and promising growth characteristics.
As such, we avoid emphasizing particular sectors or industries and, instead,
tend to remain sector neutral.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund benefited from impressive performance from several individual holdings.
In particular, furniture retailer Ethan Allen Interiors was up more than 75% for
the year, after doubling in value the previous fiscal year. Safeskin Corp., in
the health care sector, was up more than 179% for the year.
 
WERE THERE ANY PARTICULARLY WEAK HOLDINGS?*
We significantly reduced the Fund's energy weighting during the year, as oil
prices declined. Nevertheless, several of the Fund's holdings in oil service
companies, which had performed extremely well in fiscal 1997, declined nearly
50% from their highs. In addition, several stocks in the volatile health care
and technology sectors dropped in value.
 
HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
The Fund's top 10 holdings were led by five technology stocks -- Sanmina, 1.2%,
Tech Data, 1.0%, Platinum Technology, 0.9%, Aspect Telecommunications, 0.8%, and
Comverse Technology, 0.8% -- and three financial stocks -- Protective Life,
1.2%, Sirrom Capital, 0.9% and Alabama National Bancorp, 0.9%. The remaining
members of the top 10 were Ethan Allen Interiors, 1.0% and Hibbett Sporting
Goods, 0.8% (retail).
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
Looking ahead, we remain optimistic about continued U.S. economic growth and low
inflation. We believe that interest rates may decline further, which would
support ongoing stock market growth. Although the market continues to demand
liquidity, which is provided by large-capitalization stocks, the valuations in
small-company stocks are becoming more compelling on a price/earnings to growth
relationship.
 
Our overall strategy remains intact -- to take a bottom-up approach in our
search for small companies with promising growth qualities.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
The above-quoted performance data includes the performance of the Paragon Gulf
South Growth Fund for the period prior to the commencement of operations of The
One Group Small Capitalization Fund on March 26, 1996. Performance for the
Fiduciary Shares is based on Class A Share performance adjusted to reflect the
absence of sales charges.
 
The performance of the Small Capitalization Fund is measured against the S&P 600
Index, an unmanaged index generally representative of the performance of small
companies in the US stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management. By contrast, the performance of the fund
reflects the deduction of these value-added services as well as the deduction of
sales charges on Class A Shares and applicable contingent deferred sales charges
on Class B and Class C Shares.

Portfolio Performance Review
- --------------------------------------------------------------------------------
THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
HOW DID THE FUND PERFORM?
For the year ended June 30, 1998, The One Group International Equity Index Fund
Fiduciary share class provided a total return of 9.54%. (For information on
other share classes and a performance comparison to the index, please see page
27.)
 
TO WHAT DO YOU ATTRIBUTE THE FUND'S PERFORMANCE?
The Fund's strategy has two components. It seeks to invest 90% of its assets in
the developed international markets in a manner designed to track the Morgan
Stanley Capital International Europe, Australia, Far East/
Gross Domestic Product (EAFE/GDP) Index; and it invests the remaining 10% of its
assets in emerging markets.
 
Over the past 12 months, the difference in return between the developed markets
and the emerging markets was dramatic. The EAFE/GDP Index rose 15.14% over this
period, while the customized index we track in the emerging markets fell 16.09%.
The Fund's return trailed the EAFE/GDP Index due to its investments in emerging
markets and due to fees and expenses charged to the Fund. (An index has no
expenses because it is an unmanaged portfolio.)
 
WHY DID THE EMERGING MARKETS FALL SO SHARPLY?
The turmoil in the emerging markets began on July 2, 1997, when a rapid decline
in Thailand's currency precipitated an economic crisis throughout Asia. As the
region's currencies dropped, companies' foreign debts grew beyond their ability
to pay. Many companies had borrowed from foreign lenders because interest rates
were lower in those countries than they were at home. The amount of foreign debt
surprised most investors, as companies in these countries did not adequately
disclose those loans. Investors' reacted to these developments and equity prices
plunged along with the currencies.
 
WHAT ABOUT THE INFLUENCE FROM THE DEVELOPED MARKETS?
European equity markets performed very well this past year, which allowed the
Fund to achieve its positive return in spite of the turmoil in the Asian
markets. The Fund's investments in Europe started the year at more than 61% of
total assets.
 
HOW DID THE U.S. DOLLAR'S STRENGTH INFLUENCE RETURNS?
Overall performance once again was held back by a strong U.S. dollar, which
increased in value versus nearly every currency across the globe. Because the
Fund's foreign-denominated investments suffered from currency declines in all
the countries where it invests over the past year, the strong U.S. dollar
prevented the Fund from achieving a higher return.
 
DID THE PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG MARKETS?
Equity market returns across Europe outpaced even the exceptional U.S. equity
market during the past 12 months. Among the developed countries, Finland
performed best, up 66%. Other outstanding returns were posted in Italy, up 63%;
Spain, up 50%; Ireland, up 41%; and Austria, France and Germany, each up more
than 30%. European emerging countries also performed well, with Greece up 37%,
Hungary up 25%, and Turkey up 24%.
 
In contrast, performance in Asia ranged from bad to worse. Japan, the largest
weight in the Fund a year ago at 27% of assets, fell almost 32%. Among the
developed markets in Asia, Malaysia fell 75%, Hong Kong fell 48%, and Singapore
fell 48%. Results in Asia's emerging markets were even worse.
 
WHAT IS YOUR OUTLOOK FOR THE FUND?
The Fund will continue its strategy of tracking the EAFE/GDP Index with the bulk
of its assets and investing broadly across the emerging markets. We continue to
be optimistic about prospects in the European equity markets. Furthermore,
recent developments in Asia have forced these countries to address their
problems, and we expect those markets to fully recover eventually. We feel that
sticking with the Fund's strategy will allow the Fund to participate in the
recovery.

offer superb diversification, especially for an investor with a large allocation
to U.S. equities.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.
 
International investing involves increased risk and volatility.
 
The performance of the International Equity Index Fund is measured against the
Morgan Stanley EAFE/GDP Index, an unmanaged index generally representative of
the performance of international stock markets. Investors are unable to purchase
the index directly, although they can invest in the underlying securities. The
performance of the index does not reflect the deduction of expenses associated
with a mutual fund, such as investment management. By contrast, the performance
of the fund reflects the deduction of these value-added services as well as the
deduction of sales charges on Class A Shares and applicable contingent deferred
sales charges on Class B and Class C Shares.

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 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 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

</TABLE>
 
       The loaned securities were fully collateralized by cash and U.S.
       Government securities as of June 30, 1998.
 
       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 June 30, 1998,
   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 fiscal years ended June
   30, 1998 and 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 portfolio 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 year ended June 30, 1998, the Distributor received
   $23,155,470 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 $22,831,371 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 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.

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.
 
8. CONVERSION OF COMMON TRUST FUNDS:
 
   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
   is a summary of shares issued, net assets converted, net assets value per
   share issued and unrealized appreciation of assets acquired as of the
   conversion date (amounts in thousands except per share amounts):

10. SUBSEQUENT EVENTS
 
    On May 21, 1998, the Board of Trustees approved an agreement and plan of
    reorganization and liquidation ("the Plan") with the Marquis Family of Funds
    (the "Marquis Funds"). Under the Plan, the assets and liabilities of each
    Marquis fund were transferred to a comparable One Group fund. Shares of the
    comparable One Group fund were distributed to the Marquis shareholders in a
    complete liquidation of each Marquis fund. A special Shareholder Meeting to
    approve the plan was held on July 30, 1998. In a tax-free exchange on August
    10, 1998, net assets of the Marquis funds were exchanged for shares of a
    corresponding fund of The One Group as follows (amounts in thousands):

THE ONE GROUP FAMILY OF MUTUAL FUNDS                               JUNE 30, 1998
 
To the Shareholders and Board of Trustees of
  The One Group Family of Mutual Funds:
 
In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and related statements of operations, of changes
in net assets and of cash flows and the financial highlights present fairly, in
all material respects, the financial position 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 and the
International Equity Index Fund (ten series of The One Group Family of Mutual
Funds), at June 30, 1998, the results of each of their operations for the period
then ended, the changes in each of their net assets, and the cash flows of the
Asset Allocation Fund, the Growth Opportunities Fund and the International
Equity Index Fund for the periods presented and the financial highlights for
each of the periods presented, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of The One Group
Family of Mutual Funds' management; our responsibility is to express an opinion
on these financial statements based on our audits. We conducted our audits of
these financial statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at June 30, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
