Portfolio Performance Review

HOW DID THE FUND PERFORM?
One Group Small Cap Growth Fund I share class posted a total return of 32.26%
for the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see pages 4-5.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE?
The fiscal year 2000 will be remembered for the extreme volatility exhibited in
technology stocks, particularly among the Internet sector. The period from
September 1, 1999, through March 10, 2000, experienced unprecedented moves in
the technology sector, as demonstrated by the NASDAQ Composite Index
outperforming the S&P 500 Index by 78 percentage points.

This represented one of the most overly optimistic periods in market history, as
small cap growth stocks and Internet sectors, often thought of as the most
speculative style and sector of the market, benefited from valuations never seen
before. While the Internet promises to change business and the way people go
about their daily lives, the lack of earnings and negative cash flow of many new
companies eventually led to a quick correction from mid-March through the end of
May. But, even with the sector rotations that occurred, the overall market still
performed positively for the 12-month period. Furthermore, signs that the
economy may be slowing down are providing hope that the Federal Reserve will
discontinue its interest-rate-tightening campaign, allowing strong growth
companies to continue meeting expectations.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our goal is to own and overweight small-company stocks that exhibit strong
fundamentals, such as increasing earnings estimates and improving sales and
margins. Small cap companies with these characteristics often have niche
products or services that serve large or rapidly growing markets. In addition to
strong fundamentals, we favor companies with attractive valuations over those
with extremely high valuations.

In pursuit of these goals, we continued to invest in the highest growth
companies. We reduced exposure to cyclical and financial stocks and more
value-oriented sectors and increased holdings in the technology and health care
sectors, which provided the greatest growth opportunities.

Early in the fiscal year, the Fund's performance benefited from an over-weighted
position in the technology sector, particularly in the semiconductor area. But,
by February 2000, we thought that optimism and speculation were rising to
unprecedented and dangerous levels. We therefore aggressively cut the Fund's
exposure to technology and biotechnology, where speculation was the highest. In
hindsight, we implemented this strategy only a few weeks early, as the market
correction started in mid-March. Nevertheless, these moves helped lessen the
impact of the correction, and the Fund avoided some of the carnage that many
small-cap growth managers experienced.

HOW DID SECTOR ALLOCATIONS INFLUENCE FUND PERFORMANCE?*
Not surprisingly, the Fund's technology stocks had the largest positive
influence on Fund performance during the fiscal year. Specifically, the
semiconductor, communication technology and software areas offered the greatest
returns, as did participation in the Internet and IPO (initial public offering)
segments of the market. Among technology stocks (excluding most Internet
companies), fundamentals remained strong, but valuations increased significantly
in 1999 and early 2000, driving the strong performance. Internet stocks rose in
1999 and early 2000, almost exclusively on expanding valuations rather than
fundamentals, as most Internet startups lost money and generated negative cash
flows.

The health technology sector also generated strong returns for the Fund due to
the strong biotechnology performance in 1999 and early 2000. In addition,
capital equipment stocks, driven by exposure to companies with technology
end-markets, provided good returns.

The consumer-related sectors were the weakest-performing, even though consumer
spending remained high. Specifically, the consumer capital spending sector
negatively influenced performance, as higher interest rates caused
housing-related and several other industries to weaken.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Lattice Semiconductor
Corp. at 2.0% of the portfolio; SEI Corp., 1.8%; Protein Design Labs, Inc.,
1.8%; Techne Corp., 1.7%; Cognex Corp., 1.6%; Vertex Pharma, Inc., 1.6%; Jones
Pharma, Inc., 1.5%; RSA Security, Inc., 1.5%; Gentex Corp., 1.4%; and Kemet
Corp., 1.4%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We will continue to focus on finding small companies with strong market
positions and improving fundamentals that are selling at reasonable valuations.
Rather than attempting to project the direction of the overall stock market from
a top-down perspective, we direct most of our efforts toward bottom-up,
company-by-company research. We believe that uncovering companies with
upward-trending earnings estimates, good balance sheets, niche products, a
dominant market share and attractive valuations should deliver superior stock
performance over time.

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.

Small capitalization funds typically carry additional risks since smaller
companies generally have a higher risk of failure.

The above-quoted performance data includes the performance of the Paragon Gulf
South Growth Fund for the period before it was acquired by the One Group Small
Cap Growth Fund on March 26, 1996. Prior to March 26, 1996 performance for the
Class I shares is based on Class A share performance adjusted to reflect the
absence of sales charges.

The performance of the Small Cap Growth Fund is measured against the S&P
SmallCap 600 Index, an unmanaged index generally representative of the
performance of the small companies within the U.S. 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 fees. By contrast, the performance of the Fund reflects the deduction
of these 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 SmallCap 600/BARRA Growth Index represents the performance of 600 small
capitalization domestic stocks with a higher price to book ratio.

The S&P SmallCap 600/BARRA Growth Index consists of the average monthly returns
of the S&P SmallCap 600 Index for periods prior to January 1994. Thereafter, the
data is from the S&P SmallCap 600/BARRA Growth Index, which corresponds with the
initiation of the S&P SmallCap 600/BARRA Growth Index on January 1, 1994.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
One Group Small Cap Value Fund I share class posted a total return of -2.78% for
the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see pages 7-8.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE?
Overall, small-cap stocks, as measured by the S&P SmallCap 600 Index,
outperformed their large-cap counterparts, as measured by the S&P 500 Index,
during the fiscal year. The S&P SmallCap 600 Index posted a total return of
14.38%, while the total return for the S&P 500 Index was 7.25%. But, within the
styles, small-cap growth was the place to be, as evidenced by a 27.95% return in
the S&P SmallCap 600/BARRA Growth Index, versus a -0.46% return for the S&P
SmallCap 600/BARRA Value Index.

Interest rates remained on an upward course during the fiscal year. Small-cap
value stocks generally are more sensitive to interest rates and Federal Reserve
activity than other stock styles. Thus, while earnings of the underlying
companies were quite strong throughout the fiscal year, the stocks reacted
negatively to the aggressive rate-tightening policy of the Federal Reserve.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
During late 1999 and early 2000 our efforts focused on restructuring the Fund as
a more traditional-value-oriented portfolio. We sharpened our focus on stocks
with low price/earnings, low price/book and low price/ cash flow
characteristics. By focusing on strong individual companies and only purchasing
them when they were out of favor and low in price relative to earnings, we
attempted to limit downside risk while offering attractive capital appreciation.

As a result of our restructuring efforts, the Fund's P/E and other valuation
characteristics dropped considerably. In taking on a more traditional-value
orientation, the Fund was under-represented in the most highly volatile and
speculative technology sectors. This hurt the Fund's performance earlier in the
fiscal year, but it helped performance substantially as the speculative stocks
corrected later in the fiscal year.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund enjoyed strong performance from a number of stocks in the technology
sector, including Tech Data, Arrow Electronics and Park Electrochemical. The
health care sector also offered notable performance, with Amerisource Health,
Bindley Western Industries, St. Jude Medical and Quest Diagnostics posting
strong returns.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
Our restructuring efforts led to an entirely new group of top 10 holdings. As of
June 30, 2000, the list included Amerisource Health Corp. at 2.0% of the
portfolio; Smithfield Foods, Inc., 1.9%; Bindley Western Industries, Inc., 1.9%;
Foundation Health Systems, Inc., 1.7%; Ashland Co. Inc., 1.6%; Cummins Engine,
Inc., 1.6%; Kelly Services, Inc., 1.6%; Washington Federal, Inc., 1.6%; Teco
Energy, Inc., 1.6%; and Liberty Financial Companies, 1.6%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We remain optimistic toward small cap value stocks. We believe the market is
beginning to focus more broadly on the small cap sector overall, and the bloom
appears to be off the more speculative and highly valued stocks. Equally
important is the fact that this sector is especially sensitive to Federal
Reserve interest rate policy. We expect the upward trend in rates to end
sometime in the next several months. This should help the stocks in our
portfolio, as fears of higher rates come to an end.

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.

Small capitalization funds typically carry additional risks since smaller
companies generally have a higher risk of failure.

The Small Cap Value Fund commenced operations as the Pegasus Small Cap
Opportunity Fund on January 27, 1995 subsequent to the transfer of assets from a
common trust fund with materially equivalent investment objectives, policies,
guidelines and restrictions as the Fund. The quoted performance of the Fund
includes the performance of the common trust fund for the Pegasus Small Cap
Opportunity Fund for periods prior to the Fund's commencement of operations as
adjusted to reflect the expenses associated with the Fund. Common trust funds
are not registered under the Investment Company Act of 1940 ("1940 Act") and,
therefore, are not subject to certain investment restrictions, limitations and
diversification requirements imposed by the 1940 Act and the Internal Revenue
Code. If the common trust fund had been registered under the 1940 Act, its
performance may have been adversely affected. The above quoted performance data
includes the performance of a common trust fund and the Pegasus Small Cap
Opportunity Fund prior to the acquisition by the One Group Small Cap Value Fund
on March 22, 1999.

The performance of the Small Cap Value Fund is measured against the S&P SmallCap
600 Index, an unmanaged index generally representative of the performance of the
small companies within the U.S. 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 fees. By contrast, the
performance of the Fund reflects the deduction of these 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 SmallCap 600/BARRA Value Index represents the performance of 600 small
capitalization domestic stocks with a lower price to book ratio.

The S&P SmallCap 600/BARRA Value Index consists of the average monthly returns
of the S&P SmallCap 600 Index for periods prior to January 1994. Thereafter, the
data is from the S&P SmallCap 600/BARRA Value Index, which corresponds with the
initiation of the S&P SmallCap 600/ BARRA Value Index on January 1, 1994.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
The One Group Mid Cap Growth Fund I share class posted a total return of 36.65%
for the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see pages 11-12.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE?
Even though the Federal Reserve was on a tightening course during the fiscal
year, the U.S. economy continued to grow at a stronger-than-expected pace. In
addition, corporate earnings remained favorable. These factors helped generate
an overall strong, but volatile, year for growth stock performance. Returns
among mid-cap growth stocks were especially attractive. After several years of
market dominance, many large cap stocks were fully priced, prompting investors
to look for attractive alternatives among the mid-cap growth universe.

Regardless of capitalization, much of the success for growth stocks was
concentrated in a single sector: technology. Investors showed an insatiable
appetite for the fastest-growing technology companies, particularly in
Internet-related and wireless communication-related sectors. This demand for
technology companies sent stock prices soaring through mid-March 2000. For
example, during the period from July 1, 1999, through March 10, 2000, the
technology-heavy NASDAQ Composite Index increased approximately 86%.

But, in mid-March, investors became worried about the fundamentals of many
high-flying Internet and dot-com companies. This unease, coupled with growing
concerns about inflationary pressures and the Federal Reserve's response to
those pressures, ignited strong volatility among growth stocks and sent the
technology sector into a full-blown correction. NASDAQ dropped approximately 21%
from March 10, 2000, through June 30, 2000. By the end of May, though, the
situation had improved, as signs of a slowing economy emerged. This helped
reassure investors that the Federal Reserve probably was near the end of its
rate-tightening campaign. In addition, valuations on many growth stocks had
fallen to attractive levels, which lured investors back.

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.

We attempted to use the shifts in the market to reposition the portfolio and
take advantage of over- and under-valuations. For example, we began building a
solid position in the health care sector around mid-fiscal-year, when the
industry had experienced a correction and stock prices were relatively cheap.
This proved beneficial to Fund performance, as the health care sector showed a
strong turnaround during the first half of calendar year 2000. In the technology
sector, we took profits as stock prices appreciated and made purchases of
fundamentally sound companies when downside volatility caused their prices to
fall.

Overall, the strong market appreciation, particularly in the technology sector,
led to more turnover than usual. Many of the Fund's technology holdings
experienced so much growth during the fiscal year that they no longer qualified
as mid-cap stocks. Once they moved into the large-cap universe, we sold them.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The technology sector offered the best overall performance for the fiscal year.
Within the sector, the Fund's semiconductor and communication technology
holdings were the standout performers, benefiting from a strong capital spending
environment, the growth of the Internet, the need for broadband, and the
acceleration of wireless communication. Companies such as Veritas Software,
Seibel Systems, ADC Telecommunications, Analog Devices, Atmel Corp., and Xilinx
posted strong returns.

In general, portfolio holdings in the retail and consumer non-durables sectors
performed poorly. The Fund's retail stocks were hurt by competitive pressures
and the effects of higher interest rates, while consumer non-durables were hurt
by the strong economic environment.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Univision
Communications, Inc. at 2.9% of the portfolio; Waters Corp., 2.9%; Rational
Software Corp., 2.6%; Symbol Technologies, Inc., 2.5%; Atmel Corp., 2.5%; Jabil
Circuit, Inc., 2.4%; Millennium Pharmaceuticals, Inc., 2.4%; Vitesse
Semiconductor Corp., 2.3%; Calpine Corp., 2.0%; and Sepracor, Inc., 2.0%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We expect economic growth to continue but at a slower pace, as the effects of
the Federal Reserve's interest rate hikes eventually take hold. We also expect
corporate earnings growth to remain attractive. But, in an environment where
interest rates are rising and growth is slowing, investors are not likely to get
much more multiple expansion. As such, we believe earnings alone will drive
stock prices higher in the coming year.

We continue to find good investment opportunities, particularly in the
technology and health care sectors. Given the periods of strong market
volatility, we remain focused on finding companies with improving fundamentals
and reasonable valuation support. Of course, "reasonable" has become more
expensive, especially in technology, so we make these assessments relative to
the sector. While we can't be certain where the market is headed, we can stick
with companies exhibiting strong fundamentals that we think will be rewarding in
the years to come.

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 Mid Cap Growth Fund is measured against the S&P MidCap
400 Index, an unmanaged index generally representative of the performance of the
mid-size company segment of the U.S. market. This index is used by over 95% of
U.S. managers and pension plan sponsors with more than $25 billion being indexed
to the S&P MidCap 400. 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 fees. By contrast, the performance of the Fund
reflects the deduction of these 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 MidCap 400/BARRA Growth Index represents the performance of the highest
price to book securities in the S&P MidCap 400 Index.

The S&P MidCap 400/BARRA Growth Index consists of the average monthly returns of
the Russell 2000 Index for periods prior to June 1991. Thereafter, the data is
from the S&P MidCap 400/BARRA Growth Index, which corresponds with the
initiation of the S&P MidCap 400/BARRA Growth Index on June 1, 1991.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?

For the year ended June 30, 2000, One Group Mid Cap Value Fund I share class
posted a total return of 0.38%. (For information on other share classes and
performance comparisons to indexes, please see pages 15-16.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE FOR VALUE STOCKS?

Volatility--in its extreme form--was the operative word for the last 12 months.
As the tug between growth and value, or fundamentals and valuation, played out,
the market experienced wild swings. In late 1999 through early 2000 we saw many
technology and other growth stocks take charge because their fundamentals were
stronger. They exhibited greater revenue growth rates and earnings-per-share
growth rates that pushed their valuations to levels not seen in years.

But, toward the end of the fiscal year's third quarter valuations concerns
emerged, predominantly among the fastest-growing technology and Internet stocks.
Investors took note that valuations were getting more and more unreasonable,
particularly because many of the high-flying Internet stocks didn't even have
any earnings on which to base valuations. Also, it became apparent that the rosy
projections for many of the high-growth technology issues wouldn't pan out. All
of this helped make value stocks more attractive, especially as the Federal
Reserve continued to raise interest rates.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?

Our strategy involves seeking out stocks with below-average price-to-earnings
and price-to-book ratios. Our goal is to invest in attractively priced stocks
with improving earnings growth that will lead to eventual price appreciation.

It's important to emphasize that price isn't the only factor. We won't purchase
a stock simply because it is cheap. Rather, we want stocks with attractive
valuations and an "earnings catalyst," or some factor expected to improve the
company's earnings growth, such as the introduction of a new product, a
management turnaround or a merger. As such, our team of analysts spends a lot of
time seeking these catalysts.

For example, our analysts uncovered evidence that pricing among semiconductor
companies was about to improve, and the Fund was able to participate in the
strong performance of this sector. In the retail sector, the catalyst was strong
consumer confidence, which our analysts believed would positively affect retail
stocks. We were able to attractively position the Fund in this sector.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*

The Fund's best-performing sector was health technology, where our stock
selection was a significant positive factor. Companies such as Waters Corp. and
Watson Pharmaceuticals generated strong returns. The Fund also benefited
strongly from its holdings in the semiconductor industry, where companies such
as Atmel offered standout performance.

Another positive contribution came from our nimble positioning in Policy
Management Systems. In April, Electronic Data Systems (EDS) announced that it
was going to purchase the company for a 50% premium over its current price. The
deal eventually fell through, but we were able to sell the stock for the price
at which EDS intended to acquire it.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Telephone & Data
Systems, Inc. at 1.8% of the portfolio; Devon Energy Corp., 1.8%; Ambac
Financial Group, Inc., 1.4%; DST Systems, 1.3%; Sungard Data Systems, Inc. 1.3%;
Kinder Morgan, 1.3%; Weatherford International, Inc., 1.2%; E-Trade Group, Inc.,
1.2%; Broadwing, Inc., 1.2%; and RJ Reynolds Tobacco Holdings, 1.1%.

WHAT IS YOUR OUTLOOK FOR THE FUND?

We expect continued volatility in the market, but not to the extreme levels as
we saw in fiscal 2000. As valuations become more in line with historical

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 Mid Cap Value Fund is measured against the S&P MidCap 400
Index, an unmanaged index generally representative of the performance of the
mid-size company segment of the U.S. market. This index is used by over 95% of
U.S. managers and pension plan sponsors with more than $25 billion being indexed
to the S&P MidCap 400. 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 fees. By contrast, the performance of the Fund
reflects the deduction of these 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 MidCap 400/BARRA Value Index represents the performance of the lowest

The S&P MidCap 400/BARRA Value Index consists of the average monthly returns of
the Russell 2000 Index for periods prior to June 1991. Thereafter, the data is
from the S&P MidCap 400/BARRA Value Index, which corresponds with the initiation
of the S&P MidCap 400/BARRA Value Index on June 1, 1991.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
The One Group Diversified Mid Cap Fund I share class posted a total return of
14.03% for the year ended June 30, 2000. (For information on other share classes
and performance comparisons to indexes, please see pages 18-19.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE?
During the fiscal year investors played tug-of-war between increasing valuations
and an increasingly less-friendly Federal Reserve. The last quarter of calendar
year 1999 saw huge money inflows toward new economy, or "concept," stocks,
regardless of valuation. Concept stocks represent an idea or plan, but little in
the way of revenue or earnings. Hundreds of stocks enjoyed skyrocketing returns,
and for the first time in years it paid huge rewards to invest in a single
sector--technology--and almost nothing else.

Nonetheless, the tightening actions of the Federal Reserve have tempered some of
this enthusiasm so far in 2000. Many of 1999's big winners fell back to earth,
and diversified portfolios once again have been rewarded. The high volatility
that's been present since mid-March has placed emphasis on sector neutrality and
stock selection, which plays to our strengths.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Finding stocks with balance is the key to our strategy. In the value arena, we
want stocks that have good valuations along with a catalyst to prompt market
recognition of their value. Among growth names, we want stocks exhibiting strong
fundamentals at a reasonable price. This approach was ineffective during the
fourth quarter of 1999, when investors shunned balance and wanted only price
momentum. That sentiment eventually subsided, and so far in 2000, our balanced
approach has worked nicely.

The Fund held a substantial number of "old economy" stocks, and we pared back
that exposure to achieve better portfolio balance. We moved away from a heavy
emphasis on financials and industrials and more toward a blend of all economic
sectors. In particular, we added exposure to communication technology and
semiconductors, which added materially to the Fund's performance.

Our restructuring efforts resulted in a portfolio with a slight bias toward
growth stocks. At fiscal year-end, 55% of the portfolio was invested in growth
names and 45% was invested in value names. Given the market's continued fondness
for growth stocks, this orientation has served the Fund well.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The health care sector experienced a significant rebound in the first half of
calendar year 2000, and many of the Fund's holdings performed well. The Fund
also enjoyed strong performance from the communication technology sector and
select holdings within the retail sector.

The Fund endured disappointing earnings results in the capital equipment and
consumer sectors.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Waters Corp. at 3.5% of
the portfolio; Rational Software Corp., 1.9%; Kohl's Corp., 1.9%; Atmel Corp.,
1.8%; DST Systems, Inc., 1.6%; Jabil Circuit, Inc., 1.5%; Symbol Technologies,
1.4%; AptarGroup, Inc., 1.4%; Health Management Association, Inc., 1.3%; and
Univision Communications, Inc., 1.3%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Going forward, we expect the market to trade in a range, with the ceiling
provided by anticipated Federal Reserve actions and the floor provided by global
healing and an abundance of stocks substantially off their highs. We will
continue to focus on a bottom-up stock selection process, building the portfolio
one stock at a time. As always, we will seek to uncover attractively valued
stocks with improving fundamentals.

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 Diversified Mid Cap Fund commenced operations as the Pegasus Mid Cap
Opportunity Fund on June 1, 1991 subsequent to the transfer of assets from a
common trust fund with materially equivalent investment objectives, policies,
guidelines and restrictions as the Fund. The quoted performance of the Fund
includes the performance of the common trust fund for periods prior to the
Fund's commencement of operations as adjusted to reflect the expenses and sales
charges associated with the Fund. Common trust funds are not registered under
the Investment Company Act of 1940 ("1940 Act") and therefore, are not subject
to certain investment restrictions, limitations and diversification requirements
imposed by the 1940 Act and the Internal Revenue Code. If the common trust fund
had been registered under the 1940 Act, its performance may have been adversely
affected. The above quoted performance data includes the performance of a common
trust fund and the Pegasus Mid Cap Opportunity Fund prior to the acquisition by
the One Group Diversified Mid Cap Fund on March 22, 1999.

The performance of the Diversified Mid Cap Fund is measured against the S&P
MidCap 400 Index, an unmanaged index generally representative of the performance
of the mid-size company segment of the U.S. market. This index is used by over
95% of the U.S. managers and pension plan sponsors with more than $25 billion
being indexed to the S&P MidCap 400. 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 fees. By contrast, the performance of the
Fund reflects the deduction of these 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 Russell 2500 Index represents the performance of the 2500 smallest companies
in the Russell 3000 Index, which represents approximately 17% of the total
market capitalization of the Russell 3000 Index.

The benchmark index for the Diversified Mid Cap Fund has changed from the
Russell 2500 Index to the S&P MidCap 400 Index in order to better represent the
investment policies for comparison purposes.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
The One Group Large Cap Growth Fund I share class posted a total return of
15.30% for the year ended June 30, 2000. (For information on other share classes
and performance comparisons to indexes, please see page 22.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE?
Even though the Federal Reserve was on a tightening course during the fiscal
year, the U.S. economy continued to grow at a stronger-than-expected pace. In
addition, corporate earnings remained favorable. These factors helped generate
an overall strong, but volatile, year for growth stock performance.

Much of the success for growth stocks was concentrated in a single sector:
technology. Investors showed an insatiable appetite for the fastest-growing
technology companies, particularly in Internet-related and wireless
communication-related sectors. This demand for technology companies sent stock
prices soaring through mid-March 2000. For example, during the period from July
1, 1999, through March 10, 2000, the technology-heavy NASDAQ Composite Index
increased in price 86.56%.

By mid-March, investors had become increasingly worried about the fundamentals
of many high-flying Internet and dot-com companies. This unease, coupled with
growing concerns about inflationary pressures and the Federal Reserve's response
to those pressures, ignited strong volatility among growth stocks and sent the
technology sector into a full-blown correction. The NASDAQ Composite dropped
21.44% in price from March 10, 2000, through June 30, 2000. By the end of May,
though, the situation had improved, as signs of a slowing economy emerged. This
helped reassure investors that the Federal Reserve probably was near the end of
its rate-tightening campaign. In addition, valuations on many growth stocks had
fallen to attractive levels, which lured investors back.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
As always, our goal was to search for 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 a defined multiple of their
underlying industry growth rate. In addition, we search for strong management
teams and superior product positioning.

We worked toward enhancing the overall diversification of the Fund during the
year. We cut back on the Fund's "mega-cap" holdings, as some of the largest-
capitalization stocks were not the best performers over the fiscal year. In
their place we added companies further down the large-cap range.

We also varied the size of the Fund's industry weights to take advantage of
swings in the market. For example, after the health care sector experienced a
correction late in calendar year 1999, we began building a solid position in
this industry. This proved beneficial to Fund performance, as the health care
sector experienced a strong turnaround during the first half of calendar year
2000. In the technology sector, we attempted to use volatility to the Fund's
advantage, taking profits as stock prices appreciated and making purchases of
fundamentally sound companies when downside volatility caused their prices to
fall.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
Within the top-performing technology sector, the Fund's semiconductor and
communication technology holdings were the standouts. These companies benefited
from a strong capital spending environment, the growth of the Internet, the need
for broadband, and the acceleration of wireless communication. Companies such as
Applied Materials, Intel, Texas Instruments, Nortel, Oracle and Cisco Systems
all posted triple-digit returns for the fiscal year.

In general, stocks in the telephone utilities and consumer non-durables sectors
performed poorly. These companies tend to perform better in a more defensive
market environment.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included General Electric Co. at
6.8% of the portfolio; Intel Corp., 6.4%; Cisco Systems, Inc., 6.1%; Microsoft
Corp., 5.0%; Pfizer, Inc., 4.4%; EMC Corp., 2.7%; IBM Corp., 2.6%; Sun
Microsystems, Inc., 2.4%; Lucent Technologies, Inc., 2.4%; and Dell Computer
Corp., 2.1%.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

WHAT IS YOUR OUTLOOK FOR THE FUND?
We expect economic growth to continue but at a slower pace, as the effects of
the Federal Reserve's interest rate hikes eventually take hold. We also expect
corporate earnings growth to remain attractive. But, in an environment where
interest rates are rising and growth is slowing, investors are not likely to get
much more multiple expansion. As such, we believe earnings alone will drive
stock prices higher in the coming year.

We continue to find good investment opportunities, particularly in the
technology and health care sectors. Given the periods of strong market
volatility, we remain focused on finding companies with improving fundamentals
and reasonable valuation support. Of course, "reasonable" has become more
expensive, especially in technology, so we make these assessments relative to
the sector. While we can't be certain where the market is headed, we can stick
with companies exhibiting strong fundamentals that we think will be rewarding in
the years to come.

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 Cap Growth Fund is measured against the Russell
1000 Growth Index, an unmanaged index generally representative of the
performance of those Russell 1000 companies with higher price-to-book ratios and
higher forecasted growth values. 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 fees. By contrast, the performance of the
Fund reflects the deduction of these 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 500/BARRA Growth Index represents the performance of the highest price
to book securities in the S&P 500.

The benchmark index for the Large Cap Growth Fund has changed from the S&P
500/BARRA Growth Index to the Russell 1000 Growth Index in order to better
represent the investment policies for comparison purposes.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
One Group Large Cap Value Fund I share class posted a total return of -5.64% for
the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see page 25.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE FOR
VALUE STOCKS?
Volatility--in its extreme form--was the operative word for the last 12 months.
As the tug between growth and value, or fundamentals and valuation, played out,
the market experienced wild swings. In late 1999 through early 2000 we saw many
technology and other growth stocks take charge because their fundamentals were
stronger. They exhibited greater revenue growth rates and earnings-per-share
growth rates that pushed their valuations to levels not seen in years.

But, toward the end of the fiscal year's third quarter valuations concerns
emerged, predominantly among the fastest-growing technology and Internet stocks.
Investors took note that valuations were getting more and more unreasonable,
particularly because many of the high-flying Internet stocks didn't even have
any earnings on which to base valuations. Also, it became apparent that the rosy
projections for many of the high-growth technology issues wouldn't pan out. All
of this helped make value stocks more attractive, especially as the Federal
Reserve continued to raise interest rates.

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
earnings growth that will lead to eventual price appreciation.

We won't purchase a stock simply because it is cheap. Rather, we want stocks
with attractive valuations and an "earnings catalyst," or some factor expected
to improve the company's earnings growth. As such, our team of analysts spends a
lot of time seeking these catalysts. For example, our analysts uncovered
evidence that pricing among semiconductor companies was about to turn, and the
Fund was able to participate in the strong performance of this sector. In the
retail sector, the catalyst was strong consumer confidence. Our analysts
believed this would positively affect retail stocks, and we were able to
attractively position the Fund in this sector.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
As mentioned, the Fund benefited strongly from its holdings in the semiconductor
industry, which was the top-performing sector for the fiscal year. Within that
segment of the market, Micron Technology was a standout performer for the Fund.

A position in Merrill Lynch also proved rewarding for the Fund. In the beginning
of 2000, the company was lagging its competitors, but it was spending a lot of
money to make its Internet products competitive. Our analysts felt that this
represented an earnings catalyst, and that the benefits of the company's
investment in the Internet would soon come to fruition. We purchased the stock,
and it ended the fiscal year as one of the Fund's top performers.

Exposure to certain energy companies also enhanced Fund performance, as oil
prices increased sharply. Specifically, exploration and production companies,
such as Fund holding Coastal Corp., have benefited the most.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Exxon Mobil Corp. at
5.1% of the portfolio; Citigroup, Inc., 3.8%; American International Group,
Inc., 2.8%; Worldcom, Inc., 2.7%; Bell Atlantic Corp., 2.6%; SBC Communications,
Inc., 2.3%; Morgan Stanley Dean Witter Discover & Co., 2.1%; Hewlett-Packard
Co., 1.8%; Royal Dutch Petroleum Co., 1.7%; and American Home Products Corp.,
1.6%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We expect continued volatility in the market, but not to the extreme levels as
we saw in fiscal 2000. As valuations become more in line with historical
standards, volatility should begin to dissipate. Value stocks continue to trade
at a discount, while growth stocks still trade at a premium. But these
disparities are much less pronounced than previously. There always will be
pricing disparities between growth and value, and while

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 Cap Value Fund is measured against the S&P
500/BARRA 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 fees. By contrast, the
performance of the Fund reflects the deduction of these 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
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
The One Group Equity Income Fund I share class posted a total return of -8.34%
for the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see page 28.)

HOW WOULD YOU DESCRIBE THE MARKET EVENTS OF THE FISCAL YEAR?
Investors were preoccupied with the policy actions of the Federal Reserve, which
increased interest rates several times in a determined effort to moderate
economic growth and ease growing inflationary pressures. As a result, many
interest-rate-sensitive sectors performed poorly, including financials, consumer
staples and economic-sensitive industrials. As investors became increasingly
concerned about the effects of an economic slowdown, the best-performing sectors
were concentrated in the fastest-growing segments, especially technology-related
areas.

Overall, the market displayed a mix of poor breadth and concentrated leadership,
with a dramatic disparity between the performance of the broad stock market
averages and the more speculative indexes.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
In a volatile environment, we remained committed to longer-term principles. We
made investments based on reasonable prices and favorable long-term prospects.
The Fund remained concentrated in high-quality, dividend-paying,
consistent-growth companies that offer lower risk characteristics than the
market as a whole. We also used convertible securities and real estate
investment trusts (REITs) to reduce volatility and to produce high levels of
income. Our emphasis on total return helped the Fund's performance in a rapidly
shifting environment.

The major factors affecting the Fund's performance were the price weakness in
the broader market and the preference of investors for companies generating high
earnings growth. Our response was to make substantial changes in the portfolio.
The market's poor breadth gave us an opportunity to upgrade portfolio holdings
into companies with better earnings prospects, including those in the energy,
health care and technology sectors. What's more, we were able to do this without
sacrificing income. We also reduced many larger positions, took profits in
several outperformers and eliminated some laggards. We have been less patient
with turnarounds and companies that are not effectively adopting strategies to
take advantage of technological advancements.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund enjoyed solid performance from a number of holdings in various
industries. In the technology sector, Hewlett-Packard and Automatic Data offered
strong performance. In the energy sector, Mobil and El Paso Natural Gas were
among the Fund's top performers. Within the Fund's health care holdings, Warner
Lambert and Pfizer were leading performers. Also, General Electric and Monsanto
in the industrials sector and MetLife and Citigroup in the finance sector
generated attractive returns.

Fund performance also benefited from a number of multi-billion-dollar mergers,
proposed mergers and corporate restructurings, including Exxon/Mobil,
Pfizer/Warner Lambert, Dow Chemical/Union Carbide, WorldCom/Sprint, GTE/Bell
Atlantic, and BPA/Atlantic Richfield. This activity generally resulted in higher
stock prices and improved corporate focus.

Disappointing performance was related to company-specific problems resulting in
earnings shortfalls and negative reassessments by investors. Xerox, First Union,
Mattel and AT&T were among the companies experiencing such problems. In terms of
sectors, the worst performers were concentrated in the interest-rate sensitive
sectors, reflecting the pressure caused by higher interest rates.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's largest 10 holdings included General Electric
Co., at 6.6% of the portfolio; Exxon Mobil Corp., 4.7%; Pfizer, Inc., 4.0%;
Citigroup, Inc., 3.6%; Wal-Mart Stores, 3.2%; IBM Corp. Inc., 3.0%; Royal Dutch
Petroleum Co., 2.8%; American Home Products Co., 2.7%; SBC Communications, Inc.,
2.4%; and Hewlett-Packard Co., 1.9%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We believe that the past fiscal year represents a period of transition for the
economy and the stock market. We expect a more "normal" environment with returns
reverting to historical averages. Despite 2000 being an election year, the
prospect of additional Federal Reserve actions may continue to hang over the
market for some time. Stock selection will become increasingly important,
considering that the business cycle is not developing in a typical fashion.
Dynamic technological changes are affecting business, and we will have to be
observant to find those companies handling the transition successfully.

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 Income Fund is measured against the S&P 500 Index,
an unmanaged index generally representative of the performance of large
companies in the U.S. 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 fees. By contrast, the performance of the
Fund reflects the deduction of these 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
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?

For the year ended June 30, 2000, One Group Diversified Equity Fund I share
class posted a total return of 5.23%. (For information on other share classes
and performance comparisons to indexes, please see pages 30-31.)

HOW WOULD YOU DESCRIBE THE MARKET CLIMATE?

During the fiscal year investors played tug-of-war between increasing valuations
and an increasingly less-friendly Federal Reserve. The last quarter of 1999 saw
huge money inflows toward new economy, or "concept," stocks, regardless of
valuation. Hundreds of stocks enjoyed returns greater than 50%, and for the
first time in years it paid huge rewards to invest in a single
sector--technology--and almost nothing else.

The rise and fall of the concept stock played a huge part in market and Fund
performance. The company behind a concept stock has a plan, but little or no
revenues or earnings. The market was filled with these concepts, including
Internet ideas, business-to-business ideas and optical networking ideas, to name
a few. When investors were willing to buy these concepts at any price, our Fund
fared poorly in a relative sense.

The tightening actions of the Federal Reserve have tempered some of this
enthusiasm so far in 2000. Many of 1999's big winners, including the concept
stocks, fell back to earth, and diversified portfolios once again have been
rewarded. The high volatility that's been present since mid-March has placed
emphasis on sector neutrality and stock selection, two of our key strengths.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?

We look for stocks with balance. Among value names, we want stocks that have
good valuations and a catalyst, such as the introduction of a new product or the
installation of a new management team, that lets the market recognize their
value. In the growth universe, we want stocks exhibiting great fundamentals, but
at a price that makes sense. This focus on balance was ineffective during the
fourth quarter of 1999, when investors shunned balance in favor of price
momentum. But, thus far in 2000, our balanced approach once again has proven
effective.

We de-emphasized mega-cap stocks during the fiscal year, as more opportunities
emerged among stocks with market capitalizations of less than $20 billion.

Our strategies resulted in a large-cap oriented portfolio with a slight bias
toward growth stocks. At fiscal year-end, approximately 80% of the portfolio was
invested in large-cap stocks and 20% in mid-cap stocks. Growth names comprised
55% of the portfolio, while value stocks comprised 45% of the portfolio. Given
the market's continued fondness for growth stocks, this orientation has served
the Fund well.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*

The Fund's technology holdings performed very well in absolute terms, but not as
well relative to the technology concept names. The health care sector underwent
a significant rebound in the first half of 2000, and many of the Fund's holdings
in that area performed well. The Fund also enjoyed strong performance from
select financial stocks.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*

As of June 30, 2000, the Fund's top 10 holdings included General Electric Co. at
3.8% of the portfolio; Intel Corp., 3.7%; Microsoft Corp., 3.2%; Cisco Systems,
Inc., 3.1%; Exxon Mobil Corp., 2.8%; EMC Corp., 2.4%; Nortel Networks Corp.,
2.3%; Citigroup, Inc., 2.2%; Pfizer, Inc., 2.0%; and American International
Group, Inc., 1.8%.

WHAT IS YOUR OUTLOOK FOR THE FUND?

Going forward, we expect the market to trade in a range, with the ceiling
provided by anticipated Federal Reserve actions and the floor provided by global
healing and an abundance of stocks substantially off their highs. We will
continue to focus on a bottom-up stock selection process, building the portfolio
one stock at a time. As always, we will seek to uncover attractively valued
stocks with improving fundamentals.

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 before it was acquired by the One Group
Diversified Equity Fund on March 26, 1996. Prior to March 26, 1996 performance
for the Class I shares is based on Class A share performance adjusted to reflect
the absence of sales charges.

The performance of the Diversified Equity Fund is measured against the S&P 500
Index, an unmanaged index generally representative of the performance of large
companies in the U.S. 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 fees. By contrast, the performance of the
Fund reflects the deduction of these 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 SuperComposite 1500 Index represents the performance of large and small
companies in the U.S. stock market.

The S&P SuperComposite 1500 Index consists of the average monthly returns of the
S&P 500 Index for periods prior to January 1995. Thereafter, the data is from
the S&P SuperComposite 1500 Index, which corresponds with the initiation of the
S&P SuperComposite 1500 Index on January 1, 1995.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Balanced Fund I share class posted a
total return of 5.74%. (For information on other share classes and performance
comparisons to indexes, please see pages 34-35.)

WHAT WAS THE FUND'S ASSET ALLOCATION?
The Fund maintained an asset allocation of 60% stocks and 40% bonds throughout
the year. This represents a normal positioning for the Fund.

The stock component of the portfolio had an overall large-capitalization
orientation and a growth bias throughout the year. But, it's important to note
that we don't consciously overweight or underweight a single sector or a single
style of stock. Instead, we try to purchase the most attractive stocks, or those
offering greater return potential relative to their level of risk, in four
different styles--large-capitalization growth, large-capitalization value,
mid-capitalization growth and mid-capitalization value.

The fixed income portfolio was invested in a mix of Treasury, agency, corporate,
mortgage-backed and asset-backed securities.

HOW WOULD YOU DESCRIBE THE STOCK MARKET CLIMATE?
During the fiscal year investors played tug-of-war between increasing valuations
and an increasingly less-friendly Federal Reserve. The last quarter of 1999 saw
huge money inflows toward new economy, or "concept," stocks, regardless of
valuation. Concept stocks represent an idea or plan, but little in the way of
revenue or earnings. Hundreds of stocks enjoyed returns greater than 50%, and
for the first time in years it paid huge rewards to invest in a single
sector--technology--and almost nothing else. When investors were willing to buy
these concepts at any price, our portfolio fared poorly in a relative sense.

The tightening actions of the Federal Reserve have tempered some of this
enthusiasm so far in 2000. Many of 1999's big winners, including the concept
stocks, fell back to earth, and diversified portfolios once again have been
rewarded. The high volatility that's been present since mid-March has placed
emphasis on sector neutrality and stock selection, two of our key strengths.

HOW WOULD YOU DESCRIBE THE FIXED INCOME ENVIRONMENT?
During the fiscal year interest rates increased as the U.S. economy continued to
surprise investors with high levels of income growth and low inflation.
Uncomfortable with the strong economic growth and potential for future
inflation, the Federal Reserve began a series of interest rate hikes that
eventually pushed up the federal funds rate by 1.75 percentage points. But, more
important, short-term market rates rose by more than 1 percentage point, causing
prices on many of the portfolio's securities to decline.

In addition, spread volatility remained high during the year, and non-Treasury
securities underperformed. (Spreads refer to the differences in yields between
non-Treasury bonds, such as agency, corporate and mortgage-backed securities,
and comparable-maturity Treasury bonds. When spreads widen, prices on non-
Treasury bonds decline, and vice versa.) Several factors contributed to this
volatility, including Y2K worries, concerns about a more restrictive Federal
Reserve, and speculation that government surpluses would eliminate the federal
debt. Furthermore, high levels of growth among certain government agencies led
to congressional scrutiny, causing investors to question the future status of
securities issued by these agencies. In this volatile environment,
higher-quality bonds, such as those represented in the portfolio, outperformed
lower-quality securities.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS IN
THE STOCK PORTFOLIO?
Our goal is to find stocks with balance. Within the value style, we want stocks
that have good valuations along with catalysts that will bring their true value
to light. In the growth universe, we want stocks exhibiting great fundamentals,
but at a price that makes sense. This approach was ineffective during the fourth
quarter of 1999, when investors shunned balance in favor of price momentum. But,
thus far in 2000, our balanced approach once again has proven effective.

We de-emphasized the largest of the large-cap stocks during the fiscal year. We
found more opportunities among stocks with market capitalizations of less than
$20 billion.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund's technology holdings performed very well in absolute terms, but not as
well as the technology concept names. The health care sector experienced a
significant rebound in the first half of 2000, and many of the Fund's holdings
in that area performed well. The

Fund also enjoyed strong performance from many of its financial stock holdings.

WHAT WERE THE STOCK PORTFOLIO'S TOP 10 HOLDINGS?*
As of June 30, 2000, the portfolio's top 10 holdings included General Electric
Co. at 3.8% of the portfolio; Intel Corp., 3.6%; Microsoft Corp., 3.2%; Cisco
Systems, Inc., 3.1%; Exxon Mobil Corp., 2.8%; Pfizer, Inc., 2.6%; EMC Corp.,
2.4%; Citigroup, Inc., 2.3%; Nortel Networks Corp., 2.2%; and American
International Group, Inc., 1.8%.

WHAT WAS YOUR STRATEGY IN THE FIXED INCOME PORTFOLIO?
With interest rates on the upswing, we focused on higher-quality, short-maturity
securities during the year. In an effort to maintain an attractive yield, we
also focused on non-Treasury securities. During the period, the percentage of
securities rated below "AAA" decreased, due to increased exposure to government
agency debt and agency mortgage-backed securities.

The rising interest rate environment also prompted us to slightly decrease the
portfolio's duration during the fiscal year. This helped the portfolio's price
performance as rates increased. (Duration is a measure of a fund's sensitivity
to interest rate changes. A longer duration indicates greater sensitivity; a
shorter duration indicates less.) As of June 30, 2000, the portfolio's duration
was 3.5 years.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Going forward, we expect the market to trade in a range, with the ceiling
provided by anticipated Federal Reserve actions and the floor provided by global
healing and an abundance of stocks substantially off their highs. We will
continue to focus on a bottom-up stock selection process, building the portfolio
one stock at a time. As always, we will seek to uncover attractively valued
stocks with improving fundamentals.

In the fixed income portfolio, we will continue to focus on higher-quality,
non-Treasury securities because we believe they offer long-term performance
advantages. With respect to government-related securities, we likely will
continue to emphasize government agency mortgage-backed securities for their
yield advantages over Treasuries. In the corporate bond sector, we expect to
maintain our focus on higher-quality, shorter-maturity securities due to the
perceived uncertainty regarding future U.S. economic growth.

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.

Performance for the Class C shares is based on Class I share performance
adjusted to reflect the difference in expense ratios and sales charges.

The performance of the Balanced Fund is measured against the S&P 500 Index, an
unmanaged index generally representative of the performance of large companies
in the U.S. 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 fees. By contrast, the performance of the Fund
reflects the deduction of these 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 Lipper Balanced Fund Index is a blended index consisting of both stocks and
bonds with a typical stock to bond ratio of around 60% to 40%.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Equity Index Fund I share class
posted a total return of 6.86%. (For information on other share classes and
performance comparisons to indexes, please see pages 37-38.)

As it is designed to do, the Fund posted a total return similar to 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 7.25% 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 WERE THE MAJOR FACTORS CONTRIBUTING TO FUND PERFORMANCE?
In general, acceleration in earnings growth and quality of earnings of stocks in
the Index helped boost performance in the latter part of 1999. The Index's
performance slowed down during the first six months of 2000, due to the
pressures from the lack of pricing power, growing wage costs and rising interest
rates.

Our practice of purchasing and selling stocks in anticipation to the addition or
deletion from the Index helped to recover some of the costs associated with the
Fund. We systematically purchase those companies that are going to enter the
Index and sell those that are exiting based on Standard & Poor's announcements
of upcoming changes. This strategy has helped provide positive excess return.

WHICH MARKET SECTORS OFFERED NOTABLE PERFORMANCE?
The majority of the market sectors posted positive performance. Most notable,
though, was the technology sector, where attention continued to narrow and shift
toward the most extended, volatile and richly valued "new economy" stocks. For
the first half of the fiscal year, technology was the major contributor to the
Index's returns. But, during the second half of fiscal 2000, technology stocks
were laggards, and "old economy" stocks gained ground.

Index performance also was enhanced in the first half of the fiscal year by the
performance of basic materials companies, which continued to benefit from
favorable commodity prices. Specifically, within this sector specialty chemicals
and paper/forest products experienced steadily accelerating earnings.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
The major changes in the Fund's holdings during the year resulted from merger
and acquisition activity and the quarterly rebalancings of the Index. As of June
30, 2000, the Fund's top 10 holdings included General Electric Co. at 4.0% of
the portfolio; Intel Corp., 3.6%; Cisco Systems, Inc., 3.5%; Microsoft Corp.,
3.3%; Pfizer, Inc., 2.4%; Exxon Mobil Corp., 2.2%; Wal-Mart Stores, Inc., 2.0%;
Oracle Corp., 1.8%; Nortel Networks Corp., 1.7%; and Citigroup, Inc., 1.7%. All
were among the top 10 at the end of fiscal 1999 except Oracle, Nortel Networks
and Citigroup.

WHAT IS YOUR OUTLOOK FOR THE FUND?
It's possible that the equity market leadership may be on the verge of change
over the next few months, as investors respond to the inconsistency between the
pace of economic growth and consumption. The major concern would be more
prolonged Federal Reserve tightening than the consensus expects. But, as long as
more dramatic tightening is not in store, the majority of the S&P 500 stocks
should produce operating profit growth in the double-digit range similar to
fiscal 2000.

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 U.S. 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 fees. By contrast, the performance of the
Fund reflects the deduction of these 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.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
One Group Market Expansion Index Fund I share class offered a total return of
14.30% for the year ended June 30, 2000. (For information on other share classes
and performance comparisons to indexes, please see pages 40-41.)

As it is designed to do, the Fund's performance closely matched that of a market
cap-adjusted average of the returns on the S&P MidCap 400 Index and the S&P
SmallCap 600 Index. The Fund has management fees and transaction expenses that
do not apply to the indexes.

WHAT CONTRIBUTED TO THE FUND'S RETURN?
The market remained kind to mid cap growth stocks during the year, as investors
continued to expand their horizons beyond the market's largest, growth-oriented
offerings. That interest in a broader range of stocks also trickled down to the
small cap arena, where investors found many of the high-flying technology names
that experienced significant growth in late 1999 and early 2000.

WHICH MARKET SECTORS OFFERED NOTABLE PERFORMANCE?
The majority of the market sectors posted positive performance. Most notable,
though, was the technology sector, where attention continued to narrow and shift
toward the most extended, volatile and richly valued stocks. For the first half
of the fiscal year, technology was the major contributor to the Fund's returns.
But, during the second half of fiscal 2000, technology stocks were laggards, and
old economy stocks gained ground.

Index performance also was enhanced in the first half of the fiscal year by the
performance of basic materials companies, which continued to benefit from
favorable commodity prices. Specifically, within this sector specialty chemicals
and paper/forest products experienced steadily accelerating earnings.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Vitesse Semiconductor
Corp. at 1.1% of the portfolio; Calpine Corp., 1.0%; Univision Communications,
Inc., 0.9%; Dynegy, Inc., 0.9%; Millennium Pharmaceuticals, 0.8%; Jabil Circuit,
0.7%; Chiron Corp., 0.7%; Stryker Corp., 0.7%; Forest Laboratories, Inc., 0.7%;
and Waters Corp., 0.7%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
It's possible that the equity market leadership may be on the verge of change
over the next few months, as investors respond to the inconsistency between the
pace of economic growth and consumption. The major concern would be more
prolonged Federal Reserve tightening than the consensus expects. But, as long as
more dramatic tightening is not in store, the majority of the benchmarks' stocks
should produce operating profit growth in the double-digit range similar to
fiscal 2000.

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 Pegasus Market
Expansion Index Fund for the period prior to the acquisition by the One Group
Market Expansion Index Fund on March 22, 1999.

The performance of the Market Expansion Index Fund is measured against the S&P
MidCap 400 Index, an unmanaged index generally representative of the mid-cap
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 fees. By contrast, the performance of the Fund reflects
the deduction of these 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 SmallCap 600 Index is an unmanaged index generally representative of the
small companies stock market.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?

For the year ended June 30, 2000, One Group International Equity Index Fund I
share class posted a total return of 18.09%. (For information on other share
classes and performance comparisons to indexes, please see pages 43-44.)

The Fund employs a passive strategy whereby we invest 92% of 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. We invest the remaining 8% of assets to track a benchmark of equally
weighted emerging markets.

HOW WOULD YOU DESCRIBE EVENTS IN THE INTERNATIONAL STOCK MARKET?

International equity markets advanced during the fiscal year. Global economic
healing continued, and economic growth forecasts were consistently upgraded and
stronger than consensus expectations. In addition, inflation remained in check,
and several markets-- particularly emerging markets--traded at attractive
valuations.

In Europe, equity markets returned 15% during the fiscal year, as economic
growth expectations continued to improve, the increase in core inflation
remained modest and corporate earnings were revised higher. With economic growth
showing signs of life, inflation rising from low levels and money supply growth
(M3) still strong, the European Central Bank (ECB) for the first time increased
short-term interest rates during the fourth quarter of 1999. European M3
continued to increase by more than 6% during the year. This economic variable is
identified as the most important inflation indicator for the ECB, and the ECB
hiked interest rates five times, from 3.0% to 4.25%. The best performing
developed equity markets in Europe during the year were Finland, with a return
of 101%, followed by Sweden, up 65%, and France, which rose 36%.

In Asia, developed equity markets advanced 22%, with Japan gaining 27%. The
yen's appreciation of approximately 13% against the dollar mirrored investors'
growing confidence in the sustainability of the nascent Japanese recovery and
the impact on corporate profits. In emerging Asia, stock markets declined in
aggregate by 8%. India, with a return of 32%, benefited from the "new economy"
going global. World Trade Organization entry acceptance and a reduction in
tensions with Taiwan enabled China to rebound late in the year, but it still
lagged the region with a decline of 30%. The two countries that have instituted
the least policy actions in reaction to the Asian crises performed the worst:
Indonesia, which declined 48% as it struggles with political uncertainty and
unrest, and Thailand, which declined 41%.

In Latin America, stock markets returned 17%. Continued economic growth,
improving fiscal accounts from higher oil prices, and cheap valuations supported
higher equity prices. The best-performing equity markets during the year were
Brazil, with a return of 41%, Venezuela, with a gain of 12%, and Mexico, which
advanced 11%.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*

The Fund's largest country weightings as of June 30, 2000, were Japan, at 31.5%
of the portfolio; Germany, 12.7%; France, 11.8%; Italy, 8.2%; and United
Kingdom, 7.9%. As of June 30, 2000, the Fund's top 10 stock holdings included
Toyota Motor, at 2.1% of the portfolio's assets; Deutsche Telecom, 2.0%; Nippon
Telegraph and Telephone, 2.0%; Vodafone Airtouch, 1.6%; France Telecom, 1.4%;
Siemens, 1.3%; Allianze, 1.3%; Nokia, 1.3%; Telecom Italia Mobile, 1.2%; and
ENI, 1.2%.

WHAT IS YOUR OUTLOOK FOR THE FUND?

The outlook for international markets remains positive, with improving economic
growth prospects and cheaper stock valuations compared to the U.S. equity
market. We will continue our strategy of tracking the EAFE GDP Index with the
bulk of the Fund's assets and investing broadly across the emerging markets.

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 Capital International (MSCI) EAFE-GDP Index(1), 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 fees. By contrast, the performance of the Fund reflects
the deduction of these 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

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
One Group Diversified International Fund I share class posted a total return of
20.97% for the year ended June 30, 2000. (For information on other share classes
and performance comparisons to indexes, please see pages 46-47.)

HOW WOULD YOU DESCRIBE EVENTS IN THE INTERNATIONAL STOCK MARKET?
International equity markets advanced during the fiscal year. Global economic
healing continued, and economic growth forecasts were consistently upgraded and
stronger than consensus expectations. In addition, inflation remained in check,
and several markets--particularly emerging markets--traded at attractive
valuations.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary investment strategy is to invest in countries with improving
economic and stock market fundamentals at reasonable valuation levels. During
the fiscal year the global economy began to heal from the worst of the economic
recessions in several Asian countries. In anticipation of improving fundamentals
in Asia, we increased the Fund's investments in Korea, Taiwan and India. We
funded these purchases by reducing exposure to Europe.

As the phenomenon of the "new economy" went global, we increased the Fund's
weightings toward Finland and Sweden. Many of the top-performing new-economy
stocks in the communication technology sector are located in these Scandinavian
countries. Furthermore, Finland and Sweden were among the fiscal year's
strongest performers, so increasing the Fund's weighting enhanced overall
performance.

We also increased the Fund's exposure to select emerging markets. With many of
these countries trading at attractive valuations, this strategy also contributed
positively to Fund performance.

WHAT COUNTRIES DID YOU EMPHASIZE?
Our investment approach focuses on country selection based on favorable
macroeconomic and investment variables. The countries we emphasized during the
year included Japan, with a 21% average portfolio weight; United Kingdom, 13%;
Finland, 9%; France, 7% and Germany, 7%.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 2000, the Fund's top 10 holdings included Nokia at 7.2% of the
portfolio; Samsung Electronics, 1.5%; Vodafone, 1.4%; Telefonica de Espana,
1.4%; LM Ericsson, 1.4%; Telefonos de Mexico, 1.3%; Nippon Telegraph and
Telephone, 1.2%; Sony, 1.1%; British Petroleum, 1.1%; and Total Fina SA, .5%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The outlook for international markets remains positive, with improving economic
growth prospects and attractive stock market valuations compared to the U.S.
equity market. We will continue to look for countries that offer superior
expected returns while providing some protection from the volatile U.S. market.
We continue to recommend that investors have a portion of their assets invested
internationally to capture the benefits of portfolio diversification and
potential capital appreciation.

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 Diversified International Fund commenced operations as the Pegasus
International Equity Fund on December 3, 1994 subsequent to the transfer of
assets from a common trust fund with materially equivalent investment
objectives, policies, guidelines and restrictions as the Fund. The quoted
performance of the Fund includes the performance of the common trust fund for
periods prior to the Fund's commencement of operations as adjusted to reflect
the expenses and sales charges associated with the Fund. Common trust funds are
not registered under the Investment Company Act of 1940 ("1940 Act") and,
therefore, are not subject to certain investment restrictions, limitations and
diversification requirements imposed by the 1940 Act and the Internal Revenue
Code. If the common trust fund had been registered under the 1940 Act, its
performance may have been adversely affected. The above quoted performance data
includes the performance of a common trust fund and the Pegasus International
Equity Fund prior to the acquisition by the One Group Diversified International
Fund on March 22, 1999.

The performance of the Diversified International Fund is measured against the
Morgan Stanley Capital International (MSCI) EAFE + EMF Index, an unmanaged index
generally representative of the performance of international stock markets and
of emerging 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 fees. By contrast, the performance of the Fund
reflects the deduction of these 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.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 2000

1. ORGANIZATION:

   The One Group Mutual Funds (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 Small Cap
   Growth Fund, the Small Cap Value Fund, the Mid Cap Growth Fund, the Mid Cap
   Value Fund, the Diversified Mid Cap Fund, the Large Cap Growth Fund, the
   Large Cap Value Fund, the Equity Income Fund, the Diversified Equity Fund,
   the Balanced Fund, the Equity Index Fund, the Market Expansion Index Fund,
   the International Equity Index Fund and the Diversified International Fund,
   (individually a "Fund", collectively the "Funds") only. Each Fund is a
   diversified mutual fund.

2. SIGNIFICANT ACCOUNTING POLICIES:

   The following is a summary of significant accounting policies followed by the
   Trust in preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.

     SECURITY VALUATION

     Listed securities are valued at the latest available sales price on the
     principal exchange where such securities are traded. Unlisted securities or
     listed securities for which latest sales prices are not available are
     valued at the mean of the latest bid and ask price in the principal market
     where such securities are normally traded. Corporate debt securities and
     debt securities of U.S. issuers (other than short-term investments maturing
     in 60 days or less), including municipal securities, are valued on the
     basis of valuations provided by dealers or by an independent pricing
     service approved by the Board of Trustees. Short-term investments maturing
     in 60 days or less are valued at amortized cost, which approximates market
     value. Futures contracts are valued at the settlement price established
     each day by the board of trade or exchange on which they are traded.
     Options traded on an exchange are valued using the last sale price or, in
     the absence of a sale, the mean of the latest bid and ask prices. Options
     traded over-the-counter are valued using dealer-supplied valuations.
     Investments for which there are no such quotations or valuations are
     carried at fair value as determined by the Pricing Committee which is
     comprised of members from One Group Administrative Services ("OGA"), an
     affiliate of 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

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 2000

     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.

     SECURITIES LENDING

     To generate additional income, the Funds may lend up to 33 1/3% of
     securities in which they are invested pursuant to agreements requiring that
     the loan be continuously secured by any combination of cash, U.S.
     Government or U.S. Government Agency securities, or letters of credit as
     collateral equal at all times to at least 100% of the market value plus
     accrued interest on the securities lent. The Funds receive payments from
     borrowers equivalent to the dividends and interest that would have been
     earned on securities lent while simultaneously seeking to earn interest on
     the investment of cash collateral. Collateral is marked to market daily to
     provide a level of collateral at least equal to the market value of
     securities lent. There may be risks of delay in recovery of the securities
     or even loss of rights in the collateral should the borrower of the
     securities fail financially. However, loans will be made only to borrowers
     deemed by the Advisor to be of good standing and creditworthy under
     guidelines established by the Board of Trustees and when, in the judgment
     of the Advisor, the consideration which can be earned currently from such
     securities loans justifies the attendant risks. Loans are subject to
     termination by the Funds or the borrower at any time, and are, therefore,
     not considered to be illiquid investments. As of June 30, 2000, the
     following Funds had securities with the following market values on loan
     (amounts in thousands):

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 2000

     The loaned securities were fully collateralized by cash, U.S. Government
     securities and letters of credit as of June 30, 2000.

     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. Net investment income and expenses are
     recognized on the accrual basis. Dividends are recorded on the ex-dividend
     date. Interest income includes premium amortization and discount accretion
     for both financial reporting and tax purposes. Amortization and accretion
     are calculated using the effective interest method.

     EXPENSES

     Expenses directly attributable to a Fund are charged directly to that Fund,
     while the expenses, which are attributable to more than one Fund of the
     Trust, are allocated among the respective Funds. Each class of shares bears
     its pro-rata portion of expenses attributable to its series, except that
     each class separately bears expenses related specifically to that class,
     such as distribution fees.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income are declared and paid quarterly for
     the Funds except for the International Equity Index Fund and the
     Diversified International Fund which declares and pays dividends, if any,
     at least annually and the Equity Income Fund and the Balanced Fund which
     declares and pays dividends monthly. Net realized capital gains, if any,
     are distributed at least annually. Dividends are declared separately for
     each class. No class has preferential dividend rights; differences in per
     share dividend rates are due to differences in separate class expenses.

     Distributions from net investment income and from net capital gains are
     determined in accordance with income tax regulations, which may differ from
     generally accepted accounting principles. These differences are primarily
     due to differing treatments for expiring capital loss carryforwards,
     foreign currency transactions, and deferrals of certain losses. Permanent
     book and tax basis differences have been reclassified among the components
     of net assets. Certain funds also utilized earnings and profits distributed
     to shareholders on redemption of shares as part of the dividends paid
     deduction for income tax purposes.

     FEDERAL INCOME TAXES

     Each Fund intends to continue to qualify as a regulated investment company
     by complying with the provisions available to certain investment companies
     as defined in applicable sections of the Internal Revenue Code, and to make
     distributions from net investment income and from net realized capital
     gains sufficient to relieve it from all, or substantially all, federal
     income taxes. Withholding taxes on foreign dividends have been paid or
     provided for in accordance with the applicable country's tax rules and
     rates.

     DEFERRED ORGANIZATION COSTS

     Costs incurred by the Trust in connection with its organization, including
     the fees and expenses of registering and qualifying its shares for
     distribution, have been deferred. Funds commencing operations prior to June
     30, 1998, are amortizing deferred organization costs using the
     straight-line method over a period of five years. All such costs, which are
     attributable to more than one Fund of the Trust, have been allocated among
     the respective Fund's pro-rata, based on the relative net assets of each
     Fund. In the event that any of the initial shares are redeemed during such
     period by any holder thereof, the related fund will be reimbursed by such

     FINANCIAL INSTRUMENTS

     Investing in financial instruments such as options, futures, indexed
     securities and sales of forward foreign currency contracts involves risk in
     excess of the amounts reflected in the Statements of Assets and
     Liabilities. The face or contract amounts reflect the extent of the
     involvement the Funds have in the particular class of instrument. Risks
     associated with these instruments include an imperfect correlation between
     the movements in the price of the instruments and the price of the
     underlying securities and interest rates, an illiquid secondary market for
     the instruments or inability of counterparties to perform under the terms
     of the contract, and changes in the value of currency relative to the U.S.
     dollar. The Funds enter into these contracts primarily as a means to hedge
     against adverse fluctuations in the value of securities held or planned to
     be purchased by the Funds.

     FUTURES CONTRACTS

     The Funds may enter into futures contracts for the delayed delivery of
     securities at a fixed price at some future date or for the change in the
     value of a specified financial index over a predetermined time period. Cash
     or securities are deposited with brokers in order to maintain a position.
     Subsequent payments made or received by the Fund based on the daily change
     in the market value of the position are recorded as unrealized appreciation
     or depreciation until the contract is closed out, at which time the
     appreciation or depreciation is realized.

     INDEXED SECURITIES

     The Balanced Fund 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.

3. SHARES OF BENEFICIAL INTEREST:

   The Trust has an unlimited number of shares of beneficial interest, with no
   par value which may, without shareholder approval, be divided into an
   unlimited number of series of such shares, and any series may be classified
   or reclassified into one or more classes. The Trust is registered to offer
   fifty-four series and six classes of shares: Class I, Class A, Class B, Class
   C, Service Class and Class S. Currently, the Trust consists of forty-nine
   active funds. The Funds are each authorized to issue Class I, Class A, Class
   B and Class C shares only. Class A shares are subject to initial sales
   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 Funds' prospectus.
   Shareholders are entitled to one vote for each full share held and 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. See Schedules of Capital Stock Activity.

4. INVESTMENT ADVISORY, ADMINISTRATION, 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 daily net assets on the
   first $1.5 billion, 0.70% of the average daily net assets on the next $500
   million and 0.65% of the average daily net assets over $2 billion of the
   Small Cap Growth Fund, the Mid Cap Growth Fund, the Mid Cap Value Fund, the
   Large Cap Growth Fund, the Large Cap Value Fund, the Equity Income Fund, the
   Diversified Equity Fund, the Small Cap Value Fund and the Diversified Mid Cap
   Fund; 0.65% of the average daily net assets of the Balanced Fund; 0.30% of
   the average daily net assets of the Equity Index Fund; 0.35% of the average
   daily net assets of the Market Expansion Index Fund; 0.55% of the average
   daily net assets of the International Equity Index Fund; and 0.80% of the
   average daily net assets of the Diversified International Fund.

   Prior to November 1, 1999, Independence International Associates, Inc.
   ("IIA"), an indirect subsidiary of John Hancock Mutual Life Insurance
   Company, managed 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 was 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 average daily net assets

   The Trust and the Administrator, a wholly-owned subsidiary of The BISYS
   Group, Inc., are parties to an administration agreement under which the
   Administrator provides services for a fee that is computed daily and paid
   monthly, at an annual rate of 0.20% on the first $1.5 billion of Trust
   average daily net assets (excluding the Investor Growth Fund, the Investor
   Growth & Income Fund, the Investor Conservative Growth Fund, and the Investor
   Balanced Fund (the "Investor Funds") and the Treasury Only Money Market Fund,
   the Government Money Market Fund and the Institutional Prime Money Market
   Fund (the "Institutional Money Market Funds")); 0.18% on the next $0.5
   billion of Trust average daily net assets (excluding the Investor Funds and
   the Institutional Money Market Funds); and 0.16% of Trust average daily net
   assets (excluding the Investor Funds and the Institutional Money Market
   Funds) over $2 billion. OGA also serves as Sub-Administrator to each Fund of
   the Trust, pursuant to an agreement between the Administrator and OGA.
   Pursuant to this agreement, OGA performs many of the Administrator's duties,
   for which OGA receives a fee paid by the Administrator.

   The Trust and The One Group Services Company (the "Distributor") are parties
   to a distribution agreement under which shares of the Funds are sold on a
   continuous basis. Class A, Class B, and Class C shares are subject to
   distribution and shareholder services plans (the "Plans") pursuant to Rule
   12b-1 under the 1940 Act. As provided in the Plans, the Trust will pay the
   Distributor a fee of 0.35% of the average daily net assets of Class A shares
   of each of the Funds and 1.00% of the average daily net assets of the Class B
   shares and Class C shares of each of the Funds. Currently, the Distributor
   has voluntarily agreed to limit payments under the Plans to 0.25% of average
   daily net assets of the Class A shares of each Fund. Up to 0.25% of the fees
   payable under the Plans may be used as compensation for shareholder services
   by the Distributor and/or financial institutions and intermediaries. Fees
   paid under the Plans may be applied by the Distributor toward (i)
   compensation for its services in connection with distribution assistance or
   provision of shareholder services; or (ii) payments to financial institutions
   and intermediaries such as banks (including affiliates of the Advisor),
   brokers, dealers and other institutions, including the Distributor's
   affiliates and subsidiaries as compensation for services or reimbursement of
   expenses incurred in connection with distribution assistance or provision of
   shareholder services. Class I shares of each Fund are offered without
   distribution fees. For the year ended June 30, 2000, the Distributor received
   $14,902,479 from commissions earned on sales of Class A shares and redemption
   of Class B shares and Class C shares, of which, the Distributor re-allowed
   $13,009,177 to affiliated broker-dealers of the Funds.

   officers receive no compensation from the Funds for serving in their
   respective roles.

7. DEFERRED COMPENSATION PLAN:

   Independent Trustees of the Funds may participate in a Deferred Compensation
   Plan in which they may defer any or all compensation related to performance
   of their duties as a Trustee. All deferred compensation is paid by the Funds
   and invested into various One Group funds elected by each Trustee. The plan
   is fully funded and therefore, the Funds bear no additional trustee expense
   over and above the normal cash compensation.

8. CONVERSION OF COMMON TRUST FUNDS:

   The net assets of certain common trust funds managed by First Chicago NBD
   Investment Management Company (an affiliate of the Advisor) were exchanged in
   a tax-free conversion for Class I shares of the corresponding Funds. The
   transactions were accounted for by a method followed for tax purposes in a
   tax-free business combination. The following is a summary of dates, shares
   issued, net asset value per share issued and unrealized appreciation of
   assets acquired as of the conversion date (amounts in thousands, except per

Report of Independent Accountants

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

To the Board of Trustees and Shareholders of
   One Group Mutual Funds:

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of portfolio investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Small Cap Growth Fund, the
Small Cap Value Fund, the Mid Cap Growth Fund, the Mid Cap Value Fund, the
Diversified Mid Cap Fund, the Large Cap Growth Fund, the Large Cap Value Fund,
the Equity Income Fund, the Diversified Equity Fund, the Balanced Fund, the
Equity Index Fund, the Market Expansion Index Fund, the International Equity
Index Fund and the Diversified International Fund (fourteen series of One Group
Mutual Funds, hereafter referred to as the "Funds") at June 30, 2000, the
results of each of their operations for the year then ended and the changes in
each of their net assets and the financial highlights for each of the periods
presented (other than those statements of changes in net assets and financial
highlights that have been audited by other independent accountants), in
conformity with accounting principles generally accepted in the United States.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the 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 auditing standards generally accepted in the United States, 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, 2000 by correspondence with the custodian and brokers,
provide a reasonable basis for the opinion expressed above. The financial
statements of the Small Cap Value Fund, the Diversified Mid Cap Fund, the Market
Expansion Fund and the Diversified International Fund for all periods ended on
or before December 31, 1998 were audited by other independent accountants whose
report dated February 12, 1999, expressed an unqualified opinion on those
statements and financial highlights.
