HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Small Cap Growth Fund, formerly One
Group Small Capitalization Fund, I share class posted a total return of -0.72%.
(For information on other share classes and performance comparisons to indexes,
please see page 4.)

Once again, the performance of small-cap stocks generally lagged that of
larger-cap stocks, and small cap funds lagged most other stock funds during the
past year. Investors continued to favor the earnings predictability and
liquidity of large- and mid-cap stocks.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
After the Fund's focus changed from general small cap to small-cap growth in
late 1998 and early 1999, we increased the weightings of higher growth sectors,
such as technology, business and consumer services and health care, and reduced
the Fund's weightings in the commodity and manufacturing sectors. Within these
growth sectors, we selected stocks on an individual basis, relying on in-depth
research to uncover companies with promising growth characteristics.

In the current market environment, negative earnings surprises quickly and
sharply drive down stock prices. In general, stocks have continued to
underperform for long periods after the first negative fundamental news. Because
such news especially hurts higher-valuation growth stocks, we carefully
monitored several key factors to help protect the Fund from earnings
disappointments. We watched trends in earnings estimates, sales and margins, as
well as other early warning signs such as excessive inventory and receivables
growth.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The majority of the Fund's performance was driven by its largest sector,
technology. We invest approximately 25% of the Fund's assets in technology
stocks, and we plan to maintain that exposure going forward.

As has been the case for several years, many technology companies continue to
grow earnings well above 30% per year, as they fuel the growth of businesses in
all sectors of the economy. Companies such as Sanmina, a long-term holding in
the Fund with an above-average market capitalization, moved ahead 75% for the
year, as earnings expanded and the valuation became more inline with mid- and
large-cap growth stocks. The Fund is participating in the newest of industries,
the internet. With the average internet stock up more than 50% just in the first
quarter of 1999, the Fund has reaped some nice rewards from this industry.

HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
All of the Fund's top 10 holdings changed from June 30, 1998, to June 30, 1999,
as we shifted the Fund's focus to growth stocks. The top 10 holdings included
VISX Inc. (healthcare), 2.1%; FirstMerit Corp. (financial services), 1.3%;
Novellus Systems (technology), 1.2%; Valassis Comm., Inc. (utilities), 1.1%;
American Bankers Insurance (financial services), 1.0%; Legg Mason, Inc.
(financial services), 1.0%; Acxiom Corp. (business equipment & services), 1.0%;
Williams Sonoma (retail), 1.0%; Ethan Allen (shelter), 1.0%; and Gentex Corp.
(consumer durables), 0.9%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
As larger-cap valuations fell during the last several months of the fiscal year,
money flowed into smaller-cap stocks, which caused small-cap stocks to
outperform larger-cap issues. We believe this trend may continue, as large-cap
valuations remain historically high relative to small-cap valuations. Going
forward, we remain optimistic about continued U.S. economic growth and low
inflation.

Our focus will continue to be on high-quality growth companies that have capable
management teams and a reputation for delivering consistent sales and earnings
results. We believe that companies with upward-trending earnings estimates, good
balance sheets, niche products and/or a dominant market share likely will, over
the longer term, deliver superior stock performance if purchased at reasonable
valuations.

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 prior to the commencement of operations of 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/Barra
Small Cap Growth Index, an unmanaged index generally representative of the
performance of 600 small capitalization domestic stocks with a higher price to
book ratio. Investors are unable to purchase the index directly, although they
can invest in the underlying securities. The performance of the index does not
reflect the deduction of expenses associated with a mutual fund, such as
investment management. By contrast, the performance of the fund reflects the
deduction of these value-added services as well as the deduction of sales
charges on Class A Shares and applicable contingent deferred sales charges on
Class B and Class C Shares.

The S&P 600 Index represents the performance of small companies in the US stock
market.

The benchmark index for the Small Cap Growth Fund has changed from the S&P 600
Index to the S&P/Barra Small Cap Growth Index in order to better represent the
investment policies for comparison purposes.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Small Cap Value Fund I share class offered a total return of -4.48%
for the six-month period ended June 30, 1999.(1) For the year ended June 30,
1999, the Fund's total return on I shares was -13.26%. (For information on other
share classes and performance comparisons to indexes, please see page 8.)

Overall, small cap value stocks lagged most other sectors of the market during
the 12-month period. We believe this reflects an aversion to risk and shorter
investment horizon on the part of investors, given the significant economic and
political uncertainties that existed during the period. Investors continued to
prefer the liquidity and earnings visibility of large- and mid-cap growth
companies.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our ongoing, primary strategy is to attempt to invest in attractively valued
companies with strong prospects for growth and profitability. We look for
companies that have been overlooked by the market, despite having a market niche
in a growing industry, prospects for improving earnings and the potential for
higher stock valuation.

During the past year, our high-quality orientation in selecting stocks actually
hurt the Fund's performance. That was because many of the market leaders in the
small cap sector were unprofitable companies, including a number of high-flying
Internet stocks as well as troubled energy stocks and other deep cyclicals. The
Fund's emphasis on tangible earnings and reasonable valuations largely precluded
us from actively investing in these companies.

In addition, the Fund's holdings in the financial services and health care
industries detracted from performance, due to rising interest rates and new
government reimbursement proposals, respectively. However, our stock selections
in the broader technology sector and in the transportation industry were quite
favorable and added to performance during the year.

In recent months, Fund activity increased in an effort to position the Fund in a
more sector-neutral fashion. As such, we increased holdings in the financial
services and utility sectors and decreased holdings in capital goods and
technology. The number of Fund holdings also increased to gain greater
diversification and to more closely align the Fund's sector weightings with the
benchmark index.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund owned a number of outstanding performers during the last 12 months. The
largest positive contributor to performance was Quanta Services, a provider of
specialty electrical contracting and maintenance services, up by 183% since the
Fund's initial purchase in October 1998. Other strong performers included
National Instruments, Unitrode and Burr-Brown in the technology sector, and
USFreightways and C.H. Robinson in the transportation sector.

Disappointing holdings included a number of financial services holdings that
were influenced by company-specific issues, tightening credit availability and
higher interest rates. These included Stirling Cooke Brown, Unicapital and ARM
Financial Group.

HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
Most of the Fund's top 10 holdings changed during the period. At June 30, 1999,
those that remained among the top 10 included Zale Corp. (retail), 2.3%; SPS
Technologies (consumer durable), 1.8%; Universal Health Services (health care),
1.6%; and Men's Wearhouse (retail), 1.4%. The new members included USFreightways
(transportation), 1.9%; Aptargroup (consumer non-durables), 1.7%; Spartech Corp.
(raw materials), 1.7%; Dallas Semiconductor (technology), 1.6%; CH Robinson
Worldwide (transportation), 1.5% and Unitrode (technology), 1.5%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Despite the recent lagging performance of small cap stocks, we remain confident
in the merits of exposure to small companies, and we are optimistic that small
cap stocks will begin to regain some ground lost over the past four years to
large cap stocks. Economic stabilization in the Far East, interest rate cuts in
Europe and better-than-expected profitability in the United States has reduced
some of the economic uncertainty that has prevailed and prompted investors to
broaden their horizons into the small cap arena. In addition, the wide valuation
disparity between small and large companies has caught investors' attention.
Also, we have seen increased acquisition activity among smaller companies--from
larger companies with richly valued stock prices and from private buyers taking
advantage of the depressed valuations of many small companies.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

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 Pegasus Small
Cap Opportunity Fund for the period prior to the commencement of operations of
the One Group Small Cap Value Fund on March 22, 1999.

The above-quoted performance data includes the performance of a common trust
fund for the period prior to the commencement of operations of the mutual fund
on January 27, 1995, adjusted to reflect the deduction of fees and expenses.
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 performance of the Small Cap Value Fund is measured against the S&P/Barra
Small Cap Value Index, an unmanaged index generally representative of the
performance of 600 small capitalization domestic stocks with a lower price to
book ratio. Investors are unable to purchase the index directly, although they
can invest in the underlying securities. The performance of the index does not
reflect the deduction of expenses associated with a mutual fund, such as
investment management. By contrast, the performance of the fund reflects the
deduction of these value-added services as well as the deduction of sales
charges on Class A Shares and applicable contingent deferred sales charges on
Class B and Class C Shares.

The Russell 2000 Index is an unmanaged index generally representative of the
small-cap equity market.

The benchmark index for the Small Cap Value Fund has changed from the Russell
2000 Index to the S&P/Barra Small Cap Value Index in order to better represent
the investment policies for comparison purposes.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Mid Cap Growth Fund, formerly One
Group Growth Opportunities Fund, I share class posted a total return of 28.39%.
(For information on other share classes and performance comparisons to indexes,
please see page 11.)

The market uncertainty and global economic concerns that characterized much of
the fiscal year kept the country's largest, growth-oriented corporations among
the favored stock investments. Investors preferred the liquidity and earnings
stability these companies offered compared to smaller and value-oriented
companies.

However, after a series of Federal Reserve rate cuts in late 1998 helped restore
some stability to the financial markets, concerns over a global economic
slowdown gradually diminished. Also, U.S. economic growth was stronger than
expected. Investors didn't feel as compelled to own the biggest companies, and
strong earnings and solid valuations among many mid-cap growth stocks fueled
interest in this area of the market.

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 maintained a strong position in the technology sector during the year, as we
believed the industry fundamentals were compelling. As businesses continue to
strive for improvements in productivity and efficiency, spending on technology
has increased. Also, we've seen a deluge of spending on Internet-related
activities, e-commerce and Y2K readiness, all of which helped make the
technology sector the best-performing sector for the fiscal year ended June 30,
1999.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
As a group, the Fund's technology holdings offered stellar performance. Notable
performers in the technology sector included Altera Corp., Xilinx and Qualcomm.
Continued economic growth helped the retail sector post solid returns. Companies
such as Abercrombie & Fitch and Tiffany offered strong returns.

Health services stocks were among the poorest-performing due to Medicare reform
and pricing and reimbursement issues. The energy sector suffered from falling
crude oil and natural gas prices. The Fund had minimal exposure to both of these
sectors.

HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
On June 30, 1999, the Fund's top 10 holdings consisted of ten new companies
versus the top 10 of the previous fiscal year-end. They included Qualcomm
(technology), 4.1% of assets; Linear Technology (technology), 2.1%; Lexmark
International Group (technology), 1.9%; Xilinx (technology), 1.9%; Maxim
Integrated Products (technology), 1.8%; Harley Davidson (consumer durables),
1.7%; Altera (technology), 1.5%; E*Trade Group (financial services), 1.5%; and
Cintas (business equipment & services), 1.5%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
In recent years, economic growth, low inflation and relatively low interest
rates have supported strong stock returns. Investors enjoyed the benefit of
expanding price/earnings (P/E) ratios and robust earnings growth. Going forward,
we think the economy will continue to grow, inflation will remain low and
interest rates will remain low. If interest rates rise, this will put pressure
on P/E ratios, and most of the growth in stock prices will have to come from
earnings. We expect reasonably priced growth stocks to continue to do well, but
perhaps not at the pace we have seen over the last few years.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The performance of the One Group Mid Cap Growth Fund is measured against the
S&P/BARRA Midcap 400 Growth Index, an unmanaged index representing the
performance of the highest price to book securities in the S&P Midcap 400 Index.
Investors are unable to purchase the index directly, although they can invest in
the underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management. By contrast, the performance of the fund reflects the deduction of
these value-added services as well as the deduction of sales charges on Class A
Shares and applicable contingent deferred sales charges on Class B and Class C
Shares.

The S&P/BARRA Midcap 400 Growth Index for the Class I Shares consists of the
average monthly returns of the Russell 2000 Index for periods prior to June,
1991. Thereafter, the data are from the S&P/BARRA Midcap 400 Growth Index which
corresponds with the initiation of the S&P/BARRA Midcap 400 Growth Index on June
30, 1991.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Mid Cap Value Fund, formerly One
Group Disciplined Value Fund, I share class posted a total return of 3.82%. (For
information on other share classes and performance comparisons to indexes,
please see page 15.)

HOW DID MARKET EVENTS INFLUENCE FUND PERFORMANCE?
There are two factors that move stock prices -- valuation and fundamentals, such
as earnings growth. During the past fiscal year, we witnessed extreme cases of
valuation driving stock prices at certain times and fundamentals driving stock
prices at others. This created a lot of volatility and uncertainty in the
market.

At the beginning of the fiscal year, with market and economic crises developing
abroad, investors wanted to avoid stocks with foreign market exposure and to
focus on those with reliable fundamentals. As the situations in Asia, Russia and
Brazil intensified, the pool of favored stocks became narrower, and a small
group of growth stocks soared to levels not seen before. The market paid dearly
for fundamentals it could rely on, and valuation became less and less important.
Similarly, the market chose larger-capitalization stocks as its preferred
vehicle over mid- and small-capitalization stocks. As a result, in virtually any
category, large-capitalization stocks meaningfully outperformed mid-and
small-cap stocks.

Then, early in 1999, the Federal Reserve showed signs of moving toward a
tightening bias, and almost overnight investors no longer sought out stocks with
good fundamentals. They wanted valuation, and the cheaper the stock, the better.

Of course, neither of these extreme scenarios is ideal. Instead, we like to see
a proper blend of fundamentals and valuation. So, given these events, the Fund's
performance lagged in the first half of the fiscal year, when growth stocks were
the favored investment. And, even when value stocks gained strength in the
second half, the Fund did not significantly participate in the rally because the
stocks fueling the turnaround were large-cap stocks. Investors continued to
favor large-cap stocks over mid-cap stocks because of the market liquidity and
earnings predictability that larger-company stocks offered.

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 basis
research discipline -- investing in attractively priced stocks with improving
earnings growth that will lead to eventual price appreciation. We generally
focus on companies with market capitalizations of less than $7 billion.

In our search for value stocks, we look for companies that exhibit an "earnings
catalyst," or some factor expected to improve the company's earnings growth.
This catalyst can be any one of a number of factors, including introducing a new
product, implementing a management turnaround, entering a new market, etc.
During the second half of the fiscal year, there were many value stocks being
purchased, but none exhibited an earnings catalyst. We chose not to chase stocks
that we felt were inexpensively priced and would stay that way. Instead, we
remained dedicated to our long-term strategy and research discipline.

WHAT IS AN EXAMPLE OF A FUND HOLDING THAT BENEFITED FROM AN EARNINGS CATALYST?*
The Fund benefited from its technology holdings, which generally experienced
growth in revenues and earnings. In addition, earnings among technology stocks
were much more sustainable than in other industries. In particular, the Fund
benefited from its holding in LSI Logic. In the last 12 months, LSI benefited
from its ability to sell its semiconductor products into the consumer and
commercial markets, while similar companies with distribution limited to the
personal computer end markets faltered.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
Only two of the Fund's top 10 holdings -- utilities companies El Paso Energy
Corp., at 1.7% of assets, and Allegheny Energy, Inc., 1.4% -- remained among the
top 10 holdings from the previous fiscal year. The remaining eight as of June
30, 1999, included Intuit (technology), 1.6%; Marshall & Ilsley Corp. (financial

WHAT IS YOUR OUTLOOK FOR THE FUND?
While the market continues to struggle with leadership issues, we will remain
true to our management discipline and continue to look for stocks with
attractive valuations and identifiable earnings catalysts.

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/BARRA
Midcap 400 Value Index, an unmanaged index representing the performance of the
lowest price to book securities in the S&P Midcap 400 Index. Investors are
unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management. By contrast, the performance of the fund reflects the deduction of
these value-added services as well as the deduction of sales charges on Class A
Shares and applicable contingent deferred sales charges on Class B and Class C
Shares.

The S&P/BARRA Midcap 400 Value Index consists of the average monthly returns of
the S&P 500 Index for periods prior to June 1991. Thereafter, the data are from
the S&P/BARRA Midcap 400 Value Index which corresponds with the initiation of
the S&P/BARRA Midcap 400 Value Index on June 30, 1991.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the six months ended June 30, 1999, One Group Diversified Mid Cap Fund I
share class posted a total return of 8.32%.(1) For the year ended June 30, 1999,
the Fund's total return on I shares was 5.47%. (For information on other share
classes and performance comparisons to indexes, please see page 19.)

The economic backdrop over the last 12 months was ideal for equity investing.
Interest rates remained relatively steady and at low levels, inflation stayed
under control, and economic growth proceeded at a sustainable pace.

The strongest equity performers in this environment continued to be larger-cap,
growth-oriented companies. But, that phenomenon started showing some signs of
reversing toward the end of the period, as investors started seeking companies
with better value characteristics and more cyclical sensitivity. In addition,
smaller-cap stocks started gaining investor interest.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our long-standing investment strategy is to use a bottom up approach in
selecting stocks. We look for companies with sustainable, above-average growth
prospects and superior levels of profitability. We prefer companies that display
competitive advantages and are protected from new competitive threats. We also
look for companies with shareholder-oriented management, solid financial
positions and reasonable liquidity. Once we screen for these characteristics, we
employ valuation criteria to ensure we are paying a reasonable price for the
stock.

This approach has proven to be very effective over the long term. But, there are
shorter periods when other styles of investing, such as those that emphasize
pure growth with little concern for valuation, dominate the market. This was the
case for most of the past fiscal year.

In terms of tactics, we significantly increased the number of companies
represented in the portfolio, as we worked to become sector-neutral and
attempted to derive all our valued-added from stock selection. The number of
names in the portfolio increased during the period from 66 to approximately 97.

As a result of these efforts, we dramatically reduced the Fund's capital goods
exposure and substantially increased the technology exposure. We also added
holdings in the utilities sector for the first time.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
Top performers for the year included Xilinx (technology), Lexmark (technology),
Microchip Technology (technology), Waters Corp. (health care), Omnicom Group,
Inc. (business equipment & services) and Harley-Davidson (consumer durables).
Each of these companies capitalized on their competitive advantages and produced
strong earnings growth during the year.

HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
Three of the Fund's top 10 holdings at December 31, 1998 remained in the group:
Charter One Financial (financial services), 2.8% of assets; Crane Co. (capital
goods), 2.0%; and Tower Automotive (consumer durables), 2.0%; The remaining
members of the top 10 included Zale Corp. (retail), 2.1%; TCF Financial
(financial services), 2.0%; Borg-Warner Automotive (consumer durables), 1.9%;
Apache Corp. (energy), 1.9%; Legget & Platt (shelter), 1.9%; Heller Financial
(financial services), 1.8%; and Teleflex (capital goods), 1.7%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We expect the economic environment to remain relatively stable in the United
States and to improve internationally. This should prove a positive backdrop for
investing in attractively valued mid-cap stocks. In fact, we believe that
mid-cap and small-cap stocks enjoy the best relative outlook in the market, and
we will continue to seek sound companies selling at reasonable prices.

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 Mid
Cap Opportunity Fund for the period prior to the commencement of operations of
the One Group Diversified Mid Cap Fund on March 22, 1999.

The above-quoted performance data includes the performance of a common trust
fund for the period prior to the commencement of operations of the mutual fund
on June 1, 1991, adjusted to reflect the deduction of fees and expenses. 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 performance of the Diversified Mid Cap Fund is measured against the Russell
2500 Index, an unmanaged index generally representative of 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.
Investors are unable to purchase the index directly although they can invest in
the underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management. By contrast, the performance of the fund reflects the deduction of
these value-added services as well as the deduction of sales charges on Class A
Shares and applicable contingent deferred sales charges on Class B and Class C
Shares.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Large Cap Growth Fund, formerly One
Group Large Company Growth Fund, I share class posted a total return of 28.78%.
(For information on other share classes and performance comparisons to indexes,
please see page 23.)

Large-capitalization growth stocks once again offered strong, double-digit
returns. For most of the fiscal year, market uncertainty and global economic
concerns caused investors to favor the country's largest, growth-oriented
corporations because of the liquidity and earnings stability they offered.

But, after a series of Federal Reserve rate cuts in late 1998 helped restore
some stability to the financial markets, concerns over a global economic
slowdown gradually diminished. Also, U.S. economic growth was stronger than
expected. Investors didn't feel as compelled to own the biggest companies, and
strong earnings and solid valuations among many mid-cap growth stocks fueled
interest in this area of the market.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary, ongoing investment strategy is to search for good companies within
industries that are growing at a faster rate than the economy. These are
companies 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 maintained a strong position in the technology sector during the year, as we
believed the industry fundamentals were compelling. As businesses continue to
strive for improvements in productivity and efficiency, spending on technology
has increased. Also, we've seen a deluge of spending on Internet-related
activities, e-commerce and Y2K readiness, all of which helped make the
technology sector the best-performing sector for the fiscal year ended June 30,
1999.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
As a group, the Fund's technology holdings were up more than 75% for the fiscal
year. In addition, several retail holdings performed well due to continued
economic growth. Wal-Mart, Gap and Staples were among the top retail performers.
The Fund also enjoyed strong performance from a number of stocks in other
sectors, including Charles Schwab (financial services), America Online (business
equipment & services), Tele-Communications Inc. (consumer services), Comcast
(consumer services), and Tyco (capital goods).

Energy and consumer non-durable stocks were among the poorest-performing. The
energy sector suffered from falling crude oil and natural gas prices, while
consumer non-durable stocks were negatively affected by slowing demand from
foreign markets. The Fund had minimal exposure to the energy sector.

HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
As of June 30, 1999, the Fund's top 10 holdings included Microsoft (technology),
7.3% of assets; General Electric (capital goods), 6.1%; IBM (technology), 4.1%;
Cisco Systems (technology), 3.7%; Lucent Technologies (technology), 3.5%;
Wal-Mart (retail), 3.1%; Intel (technology), 2.9%; Bristol-Myers Squibb (health
care), 2.6%; MCI Worldcom (utilities), 2.5%; and Merck (health care), 2.4%. Six
of the holdings remained among the top 10 from the previous fiscal year. The
four new members included IBM, Cisco, Intel and MCI Worldcom.

WHAT IS YOUR OUTLOOK FOR THE FUND?
In recent years, economic growth, low inflation and relatively low interest
rates have supported strong stock returns. Investors enjoyed the benefit of
expanding price/earnings (P/E) ratios and robust earnings growth. Going forward,
we think the economy will continue to grow, inflation will remain low and
interest rates will remain low. If interest rates rise, this will put pressure
on P/E ratios, and most of the growth in stock prices will have to come from
earnings. We expect reasonably priced growth stocks to continue to do well, but
perhaps not at the pace we have seen over the last few years.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

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

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Large Cap Value Fund, formerly One
Group Large Company Value Fund, I share class posted a total return of 17.26%.
(For information on other share classes and performance comparisons to indexes,
please see page 26.)

HOW DID MARKET EVENTS INFLUENCE FUND PERFORMANCE?
There are two factors that move stock prices -- valuation and fundamentals, such
as earnings growth. During the past fiscal year, we witnessed extreme cases of
valuation driving stock prices at certain times and fundamentals driving stock
prices at others. This created a lot of volatility and uncertainty in the
market.

At the beginning of the fiscal year, with market and economic crises developing
abroad, investors wanted to avoid stocks with foreign market exposure and to
focus on those with reliable fundamentals. As the situations in Asia, Russia and
Brazil intensified, the pool of favored stocks became narrower, and a small
group of growth stocks soared to levels not seen before. The market paid dearly
for fundamentals it could rely on, and valuation became less and less important.
Similarly, the market chose larger-capitalization stocks as its preferred
vehicle over mid- and small-capitalization stocks. As a result, in virtually any
category, large-capitalization stocks meaningfully outperformed mid-and
small-cap stocks.

Then, early in 1999, the Federal Reserve showed signs of moving toward a
tightening bias, and almost overnight investors no longer sought out stocks with
good fundamentals. They wanted valuation, and the cheaper the stock, the better.

Of course, neither of these extreme scenarios is ideal. Instead, we like to see
a proper blend of fundamentals and valuation. Given these events, the Fund's
performance lagged somewhat in the first half of the fiscal year, when growth
stocks were the favored investment. In the second half, value stocks gained
strength, particularly large-cap value stocks, such as those the Fund invests
in. Liquidity and earnings predictability continued to sway investors, and they
found both of those qualities among the stocks of larger, value-oriented
companies.

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 basis
research discipline -- investing in attractively priced stocks with improving
earnings growth that will lead to eventual price appreciation. We generally
focus on companies with market capitalization greater than $10 billion.

In our search for value stocks, we look for companies that exhibit an "earnings
catalyst," or some factor expected to improve the company's earnings growth.
This catalyst can be any one of a number of factors, including introducing a new
product, implementing a management turnaround, entering a new market, etc.
During the second half of the fiscal year, there were many value stocks being
purchased, but none exhibited an earnings catalyst. We chose not to chase stocks
that we felt were inexpensively priced and would stay that way. Instead, we
remained dedicated to our long-term strategy and research discipline.

WHAT ARE SOME EXAMPLES OF FUND HOLDINGS THAT BENEFITED FROM AN EARNINGS
CATALYST?*
The Fund benefited from owning stock in Wells Fargo bank. This company had many
earnings catalysts, but the most notable was its merger with Norwest Corp.,
which resulted in significant revenue growth. For IBM, in the technology sector,
the catalyst was a new management team that produced stellar stock returns. The
Fund also enjoyed strong returns from Cigna, a health care insurance provider
that benefited from a merger and a subsequent transition from a general
insurance company to one specializing in health care.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 1999, the Fund's top 10 holdings included five that were part of
the top 10 last year: Citigroup (financial services), 4.3% of the Fund's assets;
Bank of America (financial services), 3.3%; IBM (technology), 2.8%; Exxon
(energy), 2.6%; and Royal Dutch Petroleum (energy), 2.1%. The remaining mem-

WHAT IS YOUR OUTLOOK FOR THE FUND?
While the market continues to struggle with leadership issues, we will remain
true to our management discipline and continue to look for stocks with
attractive valuations and identifiable earnings catalysts.

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

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Equity Income Fund, formerly One Group Income Equity Fund, I share
class posted a total return of 11.29% for the year ended June 30, 1999. (For
information on other share classes and performance comparisons to the Fund's
benchmark index, please see page 29.)

Despite mixed economic and market factors, it was the fifth-consecutive fiscal
year of double-digit returns. Throughout the period, the U.S. economy and
corporate profits performed in an exemplary manner, but near the end of the year
growing concerns over economic "overheating" and fears of higher interest rates
tempered investor enthusiasm.

TO WHAT DO YOU ATTRIBUTE SUCH STRONG PERFORMANCE?
In a market environment characterized by rotation of strength and weakness, the
Fund was rewarded by "staying the course." The Fund remained invested in a
balance of investments selected for their high current income and those selected
for their total return potential. This balance allowed the Fund to participate
in strong markets while maintaining defensive characteristics. This approach
proved beneficial, with the total return portion performing well during the
first six months of the fiscal year, as interest rates declined. In the second
half, interest rates reversed course, with interest-rate sensitive and
high-multiple growth stocks underperforming.

WHAT WERE SOME OTHER STRATEGIES AND TACTICS?
Our efforts during the fiscal year centered on managing volatility, which
remained at high levels due to a variety of developments, including the hedge
fund illiquidity crisis, the presidential impeachment trial, accelerating U.S.
economic growth, speculation in technology securities, and the crisis in Kosovo.
The result was aggressive rotation and volatile price moves in the major market
indexes. Because the Fund is targeted toward the long term, we used these big
price swings to build positions in issues we believe possess superior earnings
prospects.

The Fund's asset allocation remained unchanged from last year. On average, the
Fund held 89% of its assets in common stocks, 6% in convertible securities, 4%
in real estate investment trusts (REITs) and 1% in cash during the fiscal year.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund enjoyed solid performance from a variety of holdings in various
industries. In the communications sector, Sprint, SBC Communications and
BellSouth posted strong gains. Among technology stocks, IBM and Hewlett Packard
offered solid returns.

Retailer Wal-Mart also offered strong fiscal-year performance. In the industrial
sector, United Technologies, Dow Chemical, General Electric and Kimberly Clark
posted strong gains. And, in the energy sector, the Fund benefited from its
holdings in BP Amoco and Mobil.

Disappointing performance was related to company-specific problems that resulted
in earnings shortfalls and negative sentiment toward the company's prospects.
American Greetings, Deere, Allstate, Lockheed Martin, First Union, U.S. Bancorp
and Coca-Cola were among the poorer performers.

Our policy in handling such issues is to reduce the position size when earnings
expectations are not being met, and to sell out completely if a turnaround is
unlikely. To help avoid problem situations, we employ both strategic and
fundamental reviews in an effort to focus on areas with favorable growth
prospects.

HOW DID THE FUND'S TOP 10 HOLDINGS CHANGE?*
The Fund's holdings and largest positions changed considerably during the fiscal
year. Six new issues moved into the top 10 at year end -- IBM (technologies),
2.7%; Citigroup (financial services), 2.1%; FNMA (financial services), 2.1%;
Mobil (energy), 2.0%; SBC Communications (utilities), 2.0%; and Merck (health
care), 1.9%. The remaining four included General Electric (capital goods), 4.4%;
Exxon (energy), 2.0%; Bristol Myers Squibb (health care), 1.9%; and Bank of
America Corp. (financial services), 1.9%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
After five years of significant gains in the U.S. equity market, along with a
favorable interest rate environ-

ment and minimal inflation, it appears that conditions may be changing. With
interest rates and inflation potentially on the rise, investors must look to
better corporate earnings to lift stock prices.

The strong economy is having a favorable impact on earnings, and our
expectations are for corporate earnings to accelerate next year. In addition,
the broadening of the market should continue to favor sectors that have been
neglected in the past several years. All of this bodes well for the Fund, as our
security selection criteria places the most importance on finding good earnings,
regardless of the industry or the size of the company.

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 US stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management. By contrast, the performance of the fund
reflects the deduction of these value-added services as well as the deduction of
sales charges on Class A Shares and applicable contingent deferred sales charges
on Class B and Class C Shares.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Diversified Equity Fund, formerly One Group Value Growth Fund, I share
class posted a total return of 20.72% for the year ended June 30, 1999. (For
information on other share classes and performance comparisons to indexes,
please see page 32.)

For most of the fiscal year, large- and mid-company growth stocks continued to
outperform all other types of stocks. Then, in April, it became apparent that
worldwide economic growth would be a little better than expected. Encouraged by
this news, as well as positive first-quarter earnings surprises in a wide range
of companies, the market finally turned its attention away from the growth
sector and toward value stocks. By the end of the fiscal year, the market had
not assigned a leadership role to any one group of companies, and a "trendless"
market had emerged.

HOW DID THIS SENTIMENT INFLUENCE FUND PERFORMANCE?
From the beginning of the fiscal year through April 1999, the Fund benefited
from its overweighting in growth stocks. However, as the market sentiment
quickly shifted in April, the larger-cap, growth orientation hindered
performance somewhat. By fiscal year-end, we had reduced the Fund's growth
weighting from 62% to about 55%.

WAS THE GROWTH OVERWEIGHT AN INTENTIONAL PART OF YOUR STRATEGY?
Rather than emphasizing particular market sectors or trying to time the market's
next moves, we research, evaluate and select stocks on an individual basis to
build a diversified portfolio of our "best ideas." We don't consciously
overweight a single sector or a single style of stock. Instead, we try to
purchase the most attractive stocks, or those offering great 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.

By building a portfolio one stock at a time, we occasionally may end up with an
unintentional style bias. As such, we formally review the Fund's style bias once
a month to make sure it makes sense. While we believed that the market's bias
toward growth stocks was not sustainable over the long term, we did not expect
sentiment to change so rapidly and significantly. We expected the shift to value
stocks to be more gradual, giving us time to adjust the Fund's style bias. In
addition, many of the value-oriented stocks that moved up the fastest were those
that historically do not see such severe price appreciation.

HOW WOULD YOU SUMMARIZE YOUR STRATEGY?
Ideally, we want to find stocks with an appropriate balance of earnings
revisions and price momentum. We believe that a combination of good growth and
good value equals a good stock.

DID THE FUND BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund benefited from particularly strong performance among several individual
stocks. Wal-Mart (retail), for example, continued to beat earnings expectations
for each of the fiscal year's four quarters. Tyco International (capital goods)
posted strong results due, in part, to its purchase of Amp and its efforts in
making Amp a better-performing company. Time Warner (consumer services)
benefited from an across-the-board interest in the company's various lines of
business. America Online showed significant strength as its price increased
six-fold during the fiscal year.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
The Fund's 10 largest holdings as of June 30, 1999, included Microsoft
(technology), at 4.0% of assets; General Electric (capital goods), 3.3%; IBM
(technology), 2.7%, Intel (technology), 2.3%, Citigroup (financial services),
2.0%; Cisco Systems (technology), 2.0%; SBC Communications (utilities), 1.9%;
MCI Worldcom (utilities), 1.9%; Mobil (energy), 1.8%; Bristol-Myers Squibb
(health care), 1.8%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The significant risk factors to equities over the next year are the degree to
which international economies have or have not recovered and the degree to which
the Federal Reserve changes interest rates. At the same time, we expect stock
investors to continue searching for leadership, and in the process the market
may experience moderate volatility. Because of these factors, we will continue
to work to restore a growth/value balance in the portfolio on a stock-by-stock
basis.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The above-quoted performance data includes the performance of the Paragon Value
Equity Income Fund for the period prior to the commencement of operations of the
One Group 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 1500
Index, an unmanaged index generally representative of the performance of large
and small companies in the US stock market. Investors are unable to purchase the
index directly, although they can invest in the underlying securities. The
performance of the index does not reflect the deduction of expenses associated
with a mutual fund, such as investment management. By contrast, the performance
of the fund reflects the deduction of these value-added services as well as the
deduction of sales charges on Class A Shares and applicable contingent deferred
sales charges on Class B and Class C Shares.

The S&P 1500 Index for all classes consists of the average monthly returns of
the S&P 500 Index from December 1989 through December 1994. Thereafter, the data
are from the S&P 1500 Index which corresponds with the initiation of the S&P
1500 Index on January 1, 1995.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Balanced Fund, formerly One Group Asset Allocation Fund, I share class
posted a total return of 12.74% for the year ended June 30, 1999. (For
information on other share classes and performance comparisons to indexes,
please see page 36.)

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 slightly higher stock allocation than the previous
fiscal year, but reflects our target asset allocation.

While the stock component of the portfolio had a growth bias throughout the year
it is important to note that we don't consciously overweight 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.

By purchasing stocks one at a time, we occasionally may end up with an
unintentional style bias. As such, we formally review the portfolio's style bias
once a month to make sure it makes sense.

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

HOW DID EVENTS PLAY OUT IN THE FUND'S STOCK PORTFOLIO?
For most of the fiscal year, large- and mid-company growth stocks continued to
outperform all other types of stocks. Then, in April, it became apparent that
worldwide economic growth would be a little better than expected. Encouraged by
this news, as well as positive first-quarter earnings surprises in a wide range
of companies, the market finally turned its attention away from the growth
sector and toward value stocks. While we believed that the market's bias toward
growth stocks was not sustainable over the long term, we did not expect
sentiment to change so rapidly and significantly. We expected the shift to value
stocks to be more gradual, giving us time to adjust the portfolio's style bias.
By the end of the fiscal year, the market had not assigned a leadership role to
any one group of companies, and a "trendless" market had emerged.

HOW DID THIS SENTIMENT INFLUENCE PERFORMANCE?
From the beginning of the fiscal year through April 1999, the equity portion of
the Fund benefited from its growth-stock bias. However, as the market sentiment
quickly shifted in April, this larger-cap, growth orientation hindered
performance somewhat. By fiscal year-end, we had increased the value focus and
reduced the growth weighting from 62% to approximately 55%.

DID THE STOCK PORTFOLIO BENEFIT FROM ANY PARTICULARLY STRONG HOLDINGS?*
The Fund's stock portfolio benefited from particularly strong performance among
several individual stocks. Wal-Mart (retail), for example, continued to beat
earnings expectations for each of the fiscal year's four quarters. Tyco
International (capital goods) posted strong results due, in part, to its
purchase of Amp and its efforts in making Amp a better-performing company. Time
Warner (consumer services) benefited from an across-the-board interest in the
company's various lines of business. America Online showed significant strength
as its price increased six-fold during the fiscal year.

WHAT WERE THE STOCK PORTFOLIO'S TOP 10 HOLDINGS?*
The Fund's 10 largest stock holdings as of June 30, 1999, included Microsoft
(technology), at 4.1% of assets; General Electric (capital goods), 3.4%; IBM

WHAT WAS YOUR STRATEGY IN THE FIXED INCOME PORTFOLIO?
Early in the fiscal year, concerns about the health of the economy caused us to
increase the portfolio's credit quality and shorten the average maturity of the
corporate and asset-backed securities we held. With the possibility of a slowing
economy, the risk of corporate bankruptcies increased, so we wanted to decrease
exposure to credit risk. We also sold some Treasury

securities and increased the portfolio's agency exposure in order to gain some
yield advantage.

Despite severe volatility in the fixed income market during the fiscal year, we
eventually were rewarded for maintaining our investment discipline. Last fall,
when economic and market crises in Asia, Russia and South America emerged,
investors demanded quality securities and caused a huge rally in the U.S.
Treasury market. All other fixed income investments lagged Treasuries.
Nevertheless, we did not panic and sell our non-Treasury securities. We had
structured the portfolio with securities we believed would provide long-term
advantages over Treasuries. By the spring of 1999, the Treasury rally had
subsided, and non-Treasury securities showed significant improvement.

We also avoided significantly altering the portfolio's duration, which remained
in a neutral range of 3.5 years to 3.8 years during the year. (Duration is a
measure of a portfolio's price sensitivity to interest rate changes. A longer
duration indicates greater sensitivity; a shorter duration indicates less.)
Instead of making "bets" on interest rate movements by significantly changing
duration, we preferred to concentrate on the yield component of total return.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The significant risk factors to equities over the next year are the degree to
which international economies have or have not recovered and the degree to which
the Federal Reserve changes interest rates. At the same time, we expect stock
investors to continue searching for leadership, and in the process the market
may experience moderate volatility. Because of these factors, we will continue
to work to restore a growth/value balance in the equity portfolio on a
stock-by-stock basis.

In the fixed income portfolio, we expect to maintain our emphasis on
non-Treasury securities. We continue to believe that they offer long-term
performance advantages. Within the corporate bond sector, we expect to maintain
our focus on higher-quality, shorter-
maturity securities due to lingering uncertainty regarding interest rates and
the health of certain international 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.

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 US stock market. Investors are unable to purchase the index directly,
although they can invest in the underlying securities. The performance of the
index does not reflect the deduction of expenses associated with a mutual fund,
such as investment management. By contrast, the performance of the fund reflects
the deduction of these value-added services as well as the deduction of sales
charges on Class A Shares and applicable contingent deferred sales charges on
Class B Shares.

The Lipper Balanced Funds Index is a blended index consisting of both stocks and
bonds with a typical stock to bond ratio of around 60% to 40%.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Equity Index Fund I share class offered a total return of 22.50% for
the year ended June 30, 1999. (For information on other share classes and
performance comparisons to indexes, please see page 39.)

As it is designed to do, the Fund offered a return that nearly matched that of
the S&P 500 Index, the unmanaged group of stocks the Fund seeks to track with
little or no excess risk. The S&P 500 Index returned 22.76% 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. Also, the frequency
of cash inflows and outflows affects Fund performance.

WHAT CONTRIBUTED TO SUCH A STRONG RETURN?
Once again, corporate profits among large U.S. companies surprised investors
favorably. Year-over-year operating earnings for the S&P 500 increased more than
10%. Companies in the S&P 500 proved to have some pricing power as well as an
ability to expand margins through further cost reductions, and the Fund's
performance was correlated to those companies.

HOW DO YOU SEEK TO REDUCE TRANSACTION COSTS AND ADD TO PERFORMANCE?
Our strategy is to invest the daily cash inflows in S&P futures contracts. Once
those contracts reached about 3.5% of the Fund, we swap a small percentage back
to stocks using a process called "exchange for physical," which helps reduce
transaction costs. We also hold S&P 500 futures contracts for liquidity
purposes, and must roll them over four times a year. We use our proprietary
futures valuation model to find the best opportunities to do so as we approach
the contract expiration dates.

In addition, we implemented a new strategy called "acceleration of additions and
deletions," whereby we buy stocks in anticipation of their additions to and
deletions from the Index. Systematically, we purchase those companies that are
going to enter the Index and sell those that are exiting based on
pre-announcements. This strategy added roughly 0.12 percentage points to the
Fund's gross performance in 1999.

WHICH MARKET SECTORS OFFERED NOTABLE PERFORMANCE?
The Fund offered exposure to most economic sectors. The most active sector was
technology, which was bolstered by encouraging earnings results from Apple
Computer, Oracle, Intel, Microsoft and IBM. Internet related stocks, such as
America Online, also offered stellar returns. At year-end, the technology sector
had posted the best upward earnings revision trend over the last several months.

In addition, the utilities/telecommunications area showed positive returns, as
did many electric utilities including Bell Atlantic, BellSouth and Ameritech.
The battered energy sector was the worst-performing.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
The major changes in the Fund's holdings during the year resulted from merger
and acquisition activities and the quarterly rebalancing of the Index. Five
holdings -- Microsoft (technology), 4.0% of assets; General Electric (capital
goods), 3.3%; Wal-Mart (retail), 1.9%; Intel (technology), 1.8%; and Exxon
(energy), 1.7% -- remained among the top 10 from June 30, 1998. The remaining
five included IBM (technology), 2.1%; Cisco Systems (technology), 1.8%; Lucent
Technologies (technology), 1.8%; AT&T (utilities), 1.6%; and Merck (healthcare),
1.6%.

WHAT IS YOUR OUTLOOK FOR THE STOCK MARKET?
The stock market's negative bias toward cyclical and economic-sensitive issues
may be waning. Recently, the market has shown signs of decreased harshness
toward stocks that depend on economic strength and economy-wide pricing factors.
With regard to long-term interest rates, we believe the market will continue to
hold out for lower yields, which, along with strong economic growth, would be
positive for equity investing.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The performance of the Equity Index Fund is measured against the S&P 500 Index,
an unmanaged index generally representative of the performance of large
companies in the US stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management. By contrast, the performance of the fund
reflects the deduction of these value-added services as well as the deduction of
sales charges on Class A Shares and applicable contingent deferred sales charges
on Class B and Class C Shares.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Market Expansion Index Fund I share class offered a total return of
4.54% for the six-month period ended June 30, 1999.(1) From the Fund's inception
date, July 30, 1998, to June 30, 1999, the Fund's total return on I shares was
14.90%. (For information on other share classes and performance comparisons to
indexes, please see page 42.)

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. In addition, we expect small deviations to occur
due to slight differentials between security weightings in the Fund and
weightings in the indexes.

WHAT CONTRIBUTED TO THE FUND'S RETURN?
For much of the period, mid-cap stocks started to gain some of the ground they
had lost to their larger counterparts over the last few years. Small-cap stocks,
though, continued to lag due to investors' preference for the liquidity and
earnings stability of larger-company stocks.

Value stocks also gained some ground recently, as strong economic growth and a
rising interest rate environment favored these stocks. What's more, the strong
U.S. economy and improved prospects for the economy's future have caused
investors to reevaluate the growth prospects of many cyclical companies.

WHICH MARKET SECTORS OFFERED NOTABLE
PERFORMANCE?
The Fund offered exposure to most economic sectors. Technology stocks showed the
sharpest earnings estimate reductions over the past several months. In light of
their expanded valuations, such developments should result in a more cautious
position toward the group. From a valuation standpoint, technology stocks have
the unfortunate characteristics of eroding earnings and expanding valuations.

Financial stocks -- particularly those from larger companies -- enjoyed the
strongest earnings estimate adjustments over the past several months.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
As of June 30, 1999, the Fund's top 10 holdings included Qualcomm (technology),
at 1.6% of Fund assets; Linear Technology (technology), 0.8%; Starbucks Corp.
(retail), 0.8%; Biogen (health care), 0.8%; E*Trade Group (financial), 0.7%;
Maxim Integrated (technology), 0.7%; Lexmark International Group (technology),
0.7%, Harley-Davidson (consumer durables), 0.7%; XiLink (technology), 0.6%; and
Office Depot (retail), 0.6%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We believe that small- and mid-cap stocks are still trading near historically
low discounts to their large-cap counterparts. We believe that the performance
differences between large-cap and small- and mid-cap stocks is not sustainable
over the long term, and we expect small- and mid-cap stocks to gain some ground
in the future. We think that the momentum in the economic cycle is the key to
boosting the performance of these stocks in the near term.

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 commencement of operations of
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
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. By contrast, the performance of the fund reflects the
deduction of these value-added services as well as the deduction of sales
charges on Class A Shares and applicable contingent deferred sales charges on
Class B and Class C Shares.

The S&P 600 Index is an unmanaged index generally representative of the small
companies stock market.

Portfolio Performance Review
- --------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group International Equity Index Fund I
share class posted a total return of 11.27%. (For information on other share
classes and a performance comparison to the index, please see page 46.)

TO WHAT DO YOU ATTRIBUTE THE FUND'S PERFORMANCE?
The Fund employs a passive strategy whereby we invest 92% of its assets in the
developed international markets in a manner designed to track the Morgan Stanley
Capital International Europe, Australia, Far East Gross Domestic Product (EAFE
GDP) Index. We invest the remaining 8% of assets to track a benchmark of equally
weighted emerging markets.

The Fund's strategy of tracking the EAFE GDP index rather than the EAFE index
proved beneficial to performance. EAFE GDP has a country weighting scheme that
is more evenly distributed than that of EAFE, relying less on the performance of
only a couple large markets.

The GDP weights added value this past year, primarily due to a 10% overweight in
Japan versus the EAFE index. The Japanese market increased approximately 19%
during the year. Also, a 10% underweight in the United Kingdom also contributed
to additional returns versus EAFE, as the U.K. rose, but at a lesser rate than
Japan. The U.K. was up approximately 4%. Finally, the Fund's exposure to
emerging markets also boosted the Fund's performance, as the emerging market
index the Fund tracks rose approximately 25%.

WHAT CONTRIBUTED TO SUCH STRONG EMERGING MARKET RETURNS?
The emerging markets of Asia were among the best-performing countries, with
Thailand up 124% and Singapore up 69%. These markets rallied on strong U.S.
stock market performance and the three successive Federal Reserve rate cuts in
late 1998. These interest rate cuts raised the possibility of further rate cuts
throughout Asia. Investors also were optimistic that the economic situation in
Asia is improving.

WHAT HAPPENED IN EUROPE?
European countries were weaker during the year, pulled lower in the early part
of the period by the economic and political crisis in Russia. Later in the
fiscal year, markets were under pressure as the euro dropped on concerns about
the impact of war in Kosovo and slowing growth in Europe compared to the United
States. Austria and Norway posted the worst performance during the year, down
27% and 18%, respectively. Austrian banks fell on fears that Russian borrowers
would not be able to repay their loans. Norwegian stocks fell as a weaker
currency prompted the central bank to raise its key deposit and lending rates.
The slump in oil prices also pushed stock prices lower, as oil is the country's
main export.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
Due to the passive nature of the Fund, the largest holdings are concentrated in
the countries with the largest index weight. Japan, at 32% of assets, had the
largest weighting, followed by Germany at 12%, France at 9%, United Kingdom at
9% and Italy at 8%.

On June 30, 1999, the Fund's top 10 holdings included Nippon Telegraph and
Telephone Corp. (Japan), 2.1% of assets; Deutsche Telekom (Germany), 1.8%;
Toyota Motor Corp. (Japan), 1.7%; DaimlerChrysler (Germany), 1.6%; Allianz AG
(Germany), 1.2%; Eni (Italy), 1.0%; Bank of Tokyo Mitsubishi (Japan), 1.0%;
Mannesmann AG (Germany), 1.0%; France Telecom (France), 0.9%; BP Amoco (U.K.),
0.8%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The major factors expected to influence the international markets, and the Fund,
over the next year are the Kosovo crisis and the U.S. market. The rest of the
world has been watching the U.S. market closely to see if the stock market will
experience a correction. Also, higher interest rates in the United States
increase the chance that other markets will follow suit and raise rates. Higher
interest rates may put pressure on stock markets worldwide, while a market
correction in the United States would drag other stock markets down.

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 Fund
will be rebalanced to new GDP weights on July 1, 1999, with the major shifts in
country weights being a lower weight in Japan and a higher weight in the United
Kingdom.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

International investing involves increased risk and volatility.

The performance of the International Equity Index Fund is measured against the
Morgan Stanley EAFE/GDP Index, an unmanaged index generally representative of
the performance of international stock markets. Investors are unable to purchase
the index directly, although they can invest in the underlying securities. The
performance of the index does not reflect the deduction of expenses associated
with a mutual fund, such as investment management. By contrast, the performance
of the fund reflects the deduction of these value-added services as well as the
deduction of sales charges on Class A Shares and applicable contingent deferred
sales charges on Class B and Class C Shares.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Diversified International Fund I share class posted a total return of
8.61% for the six months ended June 30, 1999.(1) For the year ended June 30,
1999, the Fund's total return on I shares was 11.33%. (For information on other
share classes and performance comparisons to indexes, please see page 50.)

International equity markets appreciated during the 12-month period ended June
30, 1999, as economic and financial uncertainties centered in Asia, Russia and
Brazil began to ease. Equity markets rebounded after central banks around the
world cut interest rates, which improved economic growth prospects and investor
sentiment.

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. We focus
on maintaining a broadly diversified portfolio to avoid excessive risk.

Over the last 12 months, we were able to put this strategy to work in Asia.
During the last quarter of 1998, interest rates declined and the worst of the
economic recession in Asia appeared to be near. In anticipation of improving
fundamentals in Asia, we increased the Fund's investments in Japan, Singapore,
Australia and New Zealand. We funded these purchases by reducing the Fund's
European exposure and by using our cash equivalents.

In retrospect, this proved to be an important move for the Fund, as the Fund's
one-year return primarily came from investments in four countries, including
Singapore, where stock markets were up 95%, and Japan, where the market returned
30%. In addition, Finland advanced 72% for the year, and our Mexican holdings
were up 30%.

Reductions in Europe also proved to be an important decision. European countries
were weaker during the year, pulled lower in the early part of the period by the
economic and political crisis in Russia. Later in the fiscal year, markets were
under pressure as the euro dropped on concerns about the impact of war in Kosovo
and slowing growth in Europe compared to the United States.

WHAT WERE THE FUND'S TOP 10 HOLDINGS?*
The Fund's top 10 holdings on June 30, 1999, included Nokia (Finland), with a
6.2% weighting; Telefonica (Spain), 1.4%; HSBC Holdings (United Kingdom), 1.4%;
Royal Dutch Petroleum (Netherlands), 1.4%; Telefonos de Mexico (Mexico), 1.2%;
British Petroleum (United Kingdom), 1.2%; CRH (Ireland), 1.2%; British Telecom
(United Kingdom), 1.1%; Nippon Telegraph and Telephone (Japan), 1.1%; and Allied
Irish Banks (Ireland), 1.0%. Most of these holdings remained among the top 10
from the previous fiscal year-end. Only Telefonos de Mexico and Nippon Telegraph
and Telephone were new to the list since December 31, 1998.

WHAT WERE THE MAJOR COUNTRY WEIGHTINGS?
Our investment approach focuses on country selection, based on favorable
macroeconomic and investment variables. The countries we emphasized during the
year included the United Kingdom, with a 15.7% average weight; Japan, 15.1%;
Germany, 7.8%; Finland, 7.7%; France, 7.0%; Spain, 6.4%; and the Netherlands,
5.1%.

WHAT IS YOUR OUTLOOK FOR THE FUND?
While it is always difficult to forecast economic growth, we believe that our
shareholders are best served by focusing on countries with good economic growth
and low inflation, and by avoiding markets with poor economic prospects. We
expect that global economic growth will continue in the months ahead and that
the recovery in Asia will continue.

In an environment of improving global economic growth and a positive corporate
earnings outlook, several international markets appear attractive based on
various valuation measures. We continue to recommend that investors have a
portion of their assets invested internationally to capture the benefits of
portfolio diversification and capital appreciation potential.

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 above-quoted performance data includes the performance of the Pegasus
International Equity Fund for the period prior to the commencement of operations
of the One Group Diversified International Fund on March 22, 1999.

The above-quoted performance data includes the performance of a common trust
fund for the period prior to the commencement of operations of the mutual fund
on December 3, 1994, adjusted to reflect the deduction of fees and expenses.
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 performance of the Diversified International Fund is measured against the
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. By contrast, the performance of the fund reflects the deduction of
these value-added services as well as the deduction of sales charges on Class A
Shares and applicable contingent deferred sales charges on Class B and Class C
Shares.

The MSCI EAFE (Cap-Weighted) Index is an unmanaged index generally
representative of the foreign equity market as a whole.

The benchmark index for the Diversified International Fund has changed from the
MSCI EAFE (Cap-Weighted) 2000 Index to the MSCI EAFE + EMF Index in order to
better represent the investment policies for comparison purposes.

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 (previously named the Small Capitalization Fund), the Small Cap
   Value Fund (previously named the Pegasus Small Cap Opportunity Fund), the Mid
   Cap Growth Fund (previously named the Growth Opportunities Fund), Mid Cap
   Value Fund (previously named the Disciplined Value Fund), the Diversified Mid
   Cap Fund (previously named the Pegasus Mid Cap Opportunity Fund), the Large
   Cap Growth Fund (previously named the Large Company Growth Fund), the Large
   Cap Value Fund (previously named the Large Company Value Fund), the Equity
   Income Fund (previously named the Income Equity Fund), the Diversified Equity
   Fund (previously named the Value Growth Fund), the Balanced Fund (previously
   named the Asset Allocation Fund), the Equity Index Fund, the Market Expansion
   Index Fund (previously named the Pegasus Market Expansion Index Fund), the
   International Equity Index Fund and the Diversified International Fund
   (previously named the Pegasus International Equity Fund), (individually a
   "Fund", collectively the "Funds") only. Each Fund is a diversified mutual
   fund.

   The Trust entered into an Agreement and Plan of Reorganization (the "Marquis
   Agreement") with the Marquis Family of Funds ("Marquis"), a Massachusetts
   business trust. Pursuant to the Marquis Agreement, all of the assets and
   liabilities of each Marquis Fund transferred to a Fund of the One Group on
   August 10, 1998 in exchange for shares of the corresponding Fund of the One
   Group.

   The Trust entered into an Agreement and Plan of Reorganization (the "Pegasus
   Agreement") with the Pegasus Funds ("Pegasus"), a Massachusetts business
   trust. Pursuant to the Pegasus Agreement, all of the assets and liabilities
   of each Pegasus Fund transferred to a Fund of the One Group on March 22, 1999
   in exchange for shares of the corresponding Fund of the One Group. Subsequent
   to the reorganization, the fiscal period year changed from December 31 to
   June 30 for the Small Cap Value Fund, Diversified Mid Cap Fund, Market
   Expansion Index Fund and Diversified International Fund. Therefore the most
   recent period presented for the statements of operations, statements of
   changes in net assets and financial highlights for those Funds present the
   results for the six months ended June 30, 1999. Capital and share
   transactions for the periods prior to March 22, 1999 represent the
   predecessor fund.

   The Funds' investment objectives are as follows:

2. SIGNIFICANT ACCOUNTING POLICIES:

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

     SECURITY VALUATION

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

     comprised of members from Banc One Investment Advisors Corporation (the
     "Advisor") and The One Group Services Company (the "Administrator") under
     the direction of the Board of Trustees.

     FOREIGN CURRENCY TRANSLATION

     Investment valuations, other assets and liabilities initially expressed in
     foreign currencies are converted each business day into U.S. dollars based
     upon current exchange rates. Purchases and sales of foreign investments and
     income and expenses are converted into U.S. dollars based upon exchange
     rates prevailing on the respective dates of such transactions. That portion
     of realized gains or losses and unrealized appreciation or depreciation
     from investments due to fluctuations in foreign currency exchange rates is
     not separately disclosed. Such fluctuations are included with the net
     realized and unrealized gain or loss from investments.

     FORWARD FOREIGN CURRENCY CONTRACTS

     Forward foreign currency contracts are valued at the daily exchange rate of
     the underlying currency. Purchases and sales of forward foreign currency
     contracts having the same settlement date and broker are presented net on
     the Statement of Assets and Liabilities. The forward foreign currency
     exchange contracts are adjusted by the daily exchange rate of the
     underlying currency and any gains or losses are recorded for financial
     statement purposes as unrealized appreciation or depreciation until the
     contract settlement date. Gains or losses from the purchase or sale of
     forward foreign currency contracts having the same settlement date and
     broker are recorded as realized on the date of offset; otherwise gains or
     losses are recorded as realized on settlement date.

     REPURCHASE AGREEMENTS

     The Funds may invest in repurchase agreements with institutions that are
     deemed by the Advisor to be of good standing and creditworthy under
     guidelines established by the Board of Trustees. Each repurchase agreement
     is recorded at cost. The Fund requires that the securities purchased in a
     repurchase agreement transaction be transferred to the custodian in a
     manner sufficient to enable the Fund to obtain those securities in the
     event of a counterparty default. The seller, under the repurchase
     agreement, is required to maintain the value of the securities held at not
     less than the repurchase price, including accrued interest. Repurchase
     agreements are considered to be loans under the 1940 Act.

     WRITTEN OPTIONS

     The Funds may write covered call or secured put options for which premiums
     received are recorded as liabilities and are subsequently adjusted to the
     current value of the options written. Premiums received from writing
     options which expire are treated as realized gains. Premiums received from
     writing options, which are either exercised or closed, are offset against
     the proceeds received or amount paid on the transaction to determine
     realized gains or losses.

     FUTURES CONTRACTS

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

     INDEXED SECURITIES

     The 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.

     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 cash, U.S. Government or U.S.
     Government Agency securities, shares of an investment trust or mutual fund,
     letters of credit or any combination of cash, such securities, shares, 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
     continue to earn dividends and interest on securities lent while
     simultaneously seeking to earn interest on the investment of collateral.
     Collateral is marked to market daily to provide a level of collateral at
     least equal to the market value of securities lent. There may be risks of
     delay in recovery of the securities or even loss of rights in the
     collateral should the borrower of the securities fail financially. However,
     loans will be made only to borrowers deemed by the Advisor to be of good
     standing and creditworthy under guidelines established by the Board of
     Trustees and when, in the judgment of the Advisor, the consideration which
     can be earned currently from such securities loans justifies the attendant
     risks. Loans are subject to termination by the Funds or the borrower at any
     time, and are, therefore, not considered to be illiquid investments. As of
     June 30, 1999, the following Funds had securities with the following market
     values on loan (amounts in thousands):

     The loaned securities were fully collateralized by cash and U.S. Government
     securities, equities, corporate bonds and commercial paper as of June 30,
     1999.

     SECURITY TRANSACTIONS AND RELATED INCOME

     Security transactions are accounted for on a trade date basis. Net realized
     gains or losses from sales of securities are determined on the specific
     identification cost method. Interest income and expenses are recognized on
     the accrual basis. Dividends are recorded on the ex-dividend date. Interest
     income, including any discount or premium, is accrued as earned using the
     effective interest method.

     EXPENSES

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

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

     Distributions from net investment income and from net capital gains are
     determined in accordance with income tax regulations, which may differ from
     generally accepted accounting principles. These differences are primarily
     due to differing treatments for expiring capital loss carryforwards,
     foreign currency transactions, and deferrals of certain losses. Permanent
     book and tax basis differences have been reclassified among the components
     of net assets.

     FEDERAL INCOME TAXES

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

3. SHARES OF BENEFICIAL INTEREST:

   The Trust has an unlimited number of shares of beneficial interest, with no
   par value which may, without shareholder approval, be divided into an
   unlimited number of series of such shares, and any series may be classified
   or reclassified into one or more classes. The Trust is registered to offer
   fifty-nine series and five classes of shares: Class I, Class A, Class B,
   Class C and Service Class (Prior to November 1, 1998, Class I was known as
   Fiduciary Class). 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. Class A shares are subject to initial sales charges, imposed at the
   time of purchase, in accordance with the Fund's prospectus. Certain
   redemptions of Class B and Class C shares are subject to contingent deferred
   sales charges in accordance with the Fund's prospectus. As of June 30, 1999,
   there were no shareholders in Class C of the Balanced Fund. 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. The
   following is a summary of transactions in fund shares for the periods noted:

   the Advisor receives a fee paid by the Administrator.

   Prior to March 22, 1999 FCNIMCO and BISYS Fund Services ("Co-Administrators")

6. FINANCIAL INSTRUMENTS:

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

   The following is a summary of option activity for the year ended June 30,
   1999 by the Funds (amounts in thousands):

    approximating $20 million.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

To the Shareholders and Board of Trustees 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, of changes in net assets and of cash flows and the financial
highlights present fairly, in all material respects, the financial position of
the Small Cap Growth Fund (formerly the Small Capitalization Fund), the Small
Cap Value Fund (formerly the Pegasus Small Cap Opportunity Fund), the Mid Cap
Growth Fund (formerly the Growth Opportunities Fund), the Mid Cap Value Fund
(formerly the Disciplined Value Fund), the Diversified Mid Cap Fund (formerly
the Pegasus Mid Cap Opportunity Fund), the Large Cap Growth Fund (formerly the
Large Company Growth Fund), the Large Cap Value Fund (formerly the Large Company
Value Fund), the Equity Income Fund (formerly the Income Equity Fund), the
Diversified Equity Fund (formerly the Value Growth Fund), the Balanced Fund
(formerly the Asset Allocation Fund), the Equity Index Fund, the Market
Expansion Fund (formerly the Pegasus Market Expansion Fund), the International
Equity Index Fund and the Diversified International Fund (formerly the Pegasus
International Equity Fund) (fourteen series of One Group Mutual Funds, hereafter
referred to as the "Funds") at June 30, 1999, the results of each of their
operations for each of the periods presented, the changes in each of their net
assets for each of the periods presented, the cash flows of the International
Mid Cap Growth Fund and the Equity Index Fund for the year then ended and the
financial highlights for each of the periods presented (other than those
statements of operations, statements of changes in net assets and financial
highlights that have been audited by other independent accountants), in
conformity with generally accepted accounting principles. 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 statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at June 30, 1999 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.
