HOW DID THE FUND PERFORM?
One Group Ultra Short-Term Bond Fund, formerly One Group Ultra Short Term Income
Fund, I share class posted a total return of 4.66% for the year ended June 30,
1999. (For information on other share classes and performance comparisons to
indexes, please see page 4.)

HOW WOULD YOU DESCRIBE FISCAL 1999'S MARKET CLIMATE?
The fiscal year ending June 30, 1999, can be characterized as an incredibly
turbulent period in the fixed income market. In the fall of 1998, interest rates
hit new lows in the wake of emerging market and hedge fund crises. Concern over
the stability of the financial markets led the Federal Reserve to cut interest
rates three times during the second half of 1998. While interest rates were
falling, interest rate volatility and credit quality spreads were rising to
levels not seen in nearly a decade. (Spreads refer to the difference in yield
between non-Treasury securities, such as agency, corporate and mortgage-backed
bonds, and comparable-maturity Treasury bonds. When spreads widen, prices on
non-Treasury bonds decline, and vice versa.) To compound the problem, the low
interest rates led to significant mortgage refinancing activity, putting further
negative pressure on mortgage-backed securities.

As the fiscal year progressed, interest rates started showing an upward trend.
In addition, liquidity improved and spreads began to tighten. Mortgage-backed
bonds, highly rated corporate bonds and asset-backed securities outperformed
Treasuries in the first quarter of 1999. Economic indicators began to show that
the economy had not been negatively affected by the liquidity crisis in the
fall.

The final quarter of the fiscal year proved to the markets that the volatility
and liquidity problems of 1998 had not been completely erased. As the U.S.
economy continued growing at a rapid pace, the Federal Reserve took action with
an interest rate increase at the end of June. In anticipation of this move,
interest rate volatility surged and quality spreads again widened.

HOW DID THESE EVENTS INFLUENCE THE FUND?
The significant increase in quality spreads, particularly those of lower-rated
asset-backed securities, negatively affected the Fund's one-year performance. In
addition, the high concentration of floating-rate securities negatively
influenced the Fund's return by generating lower income as rates were declining.
At the same time, their prices were falling due to the rise in quality spreads.

The Fund's 30-day SEC yield declined from 5.85% on June 30, 1998, to 5.35% on
June 30, 1999 (I share class). This decline was due in part to an increase of
Fund inflows, which caused the Fund to grow by approximately 30% during the
period. This growth, given the current level of short-term rates, has had a
significant dilutive effect on the Fund. Also, in order to reduce the Fund's
volatility in the difficult market, we increased the Fund's allocation to very
short, high-quality floating-rate asset-backed securities. While spreads
widened, the fact that the coupons on these securities were indexed to money
market rates, which remained very low, pushed the Fund's yield lower.

The rising rate environment contributed to a decline in share price for the
Fund. However, the high level of income more than offset the price depreciation.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our ongoing strategy is to attempt to maximize total return while maintaining a
relatively stable share price. To that end, we invested primarily in fixed- and
floating-rate asset-backed and mortgage-backed securities of high quality that
offer significant yield advantages over comparable maturity Treasury securities.

We also focused on keeping the Fund's duration close to its target of 0.90
years. (Duration is a measure of a fund's sensitivity to interest rate changes.
A longer duration indicates greater sensitivity; a shorter duration indicates
less.) Throughout the year, duration varied from 0.85 years to 1.03 years due to
the varying duration of mortgage-backed securities and to the increased interest
rate volatility.

WHAT IS YOUR OUTLOOK FOR THE FUND?
In the short term, given the uncertainty surrounding inflation, economic growth
and Federal Reserve policy, we expect rates and spreads to remain volatile.
Later in the year, we believe the economy may start showing signs of a slowdown,
which should alleviate any additional pressure on the Fed to continue raising
rates. We expect interest rates to remain steady or moderately decline by the
end of 1999. We also expect the yield curve to remain flat and overall interest
rate volatility to drop. As such, the spread sectors may perform very well
throughout the rest of the calendar year. We plan to continue emphasizing these
securities over Treasuries.

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 Ultra Short-Term Bond Fund is measured against the
Merrill Lynch 1 Year Treasury Bill Index, an unmanaged index which reflects the
total return of a hypothetical Treasury bill with a discount rate equal to the
average rate established at each of the auctions during a given year. 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 Mix consists of an average of the Lipper ARM index that invests at
least 65% of its assets in adjustable rate mortgage securities or other
securities collateralized by or representing an interest in mortgages and the
Lipper Ultra Short-Term Index that invests at least 65% of its assets in
investment grade debt issues or better, and maintain a portfolio dollar-weighted
average maturity between 91 days and 365 days.

The Lehman Brothers 1 to 3 Year Government Index is comprised of US Government
and agency securities with maturities of one to three years.

The benchmark index for the Ultra Short-Term Bond Fund was changed from the
Lehman Brothers 1 to 3 Year Government Index to the Merrill Lynch 1 year
Treasury Bill Index in order to better represent the investment policies for
comparison purposes.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Short-Term Bond Fund, formerly One
Group Limited Volatility Bond Fund, I share class posted a total return of
4.67%. (For information on other share classes and performance comparisons to
indexes, please see page 6.)

The Fund's I share class generated income of approximately 5.7% during the year,
which was offset somewhat by an approximate 1.0% decline in share price. Higher
interest rates and wider yield spreads led to price depreciation over the
12-month period, but income was high enough to more than offset the general
price decline and provide a positive return for the Fund. (Yield spreads refer
to the difference in yield between non-Treasury securities, such as agency,
corporate and mortgage-backed bonds, and comparable-maturity Treasury bonds.
When spreads widen, prices on non-Treasury bonds decline, and vice versa.)

HOW DID THE FUND'S YIELD CHANGE?
The Fund's 30-day SEC yield moved slightly lower during the year, to 5.66% on
June 30, 1999, compared to 5.75% on June 30, 1998 (I share class).

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Consistent with our investment philosophy, our strategy was to search for value
based on thorough credit and risk/return analysis across all sectors of the
fixed income market. We maintained a bias toward "AAA"-rated asset-backed and
mortgage-backed securities due to the yield advantages these securities offered
over Treasuries. However, Treasuries remained the best performing sector of the
market for the entire 12-month period, fueled by a "flight to quality" that
emerged in the fall of 1998. Concern over financial turmoil in Asia and other
emerging markets led to a rally in the Treasury market, with other sectors of
the fixed income market falling out of favor with investors. While corporate
bonds and asset- and mortgage-backed securities had not fully recovered by
fiscal year-end, liquidity slowly has been returning to these sectors and
valuations appear much more reasonable than levels seen in early 1999.

Because of these events and 1999's growing fears of inflation, we carefully
controlled the Fund's duration, which ended the fiscal year at 1.8 years,
compared to 2.4 years on June 30, 1998. (Duration is a measure of a fund's
sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.)

Given the economic and market uncertainties characteristic of the period, we
maintained a high-quality portfolio during the year, with the Fund's average
quality higher than it was a year earlier. On June 30, 1999, 81.0% of the
portfolio's securities were rated AAA, 3.4% were rated AA, 15.4% were rated A,
and 0.2% were rated BBB, compared to 78.9% AAA-rated, 0.9% AA-rated, 18.2%
A-rated, and 2.0% BBB-rated on June 30, 1998.*

WHAT IS YOUR OUTLOOK FOR THE FUND?
Much of the Fund's performance -- and that of all domestic fixed income
portfolios -- is contingent on economic activity. If the economy moderates from
its current rapid growth pace, yields likely will decline, resulting in an
increase in bond prices and in the Fund's share price. If the economy continues
to show strength and yields increase, bond prices and the Fund's share price
likely will decline.

Our longer-term outlook on yield spreads remains positive, but we continue to
advocate a bias toward high-quality securities.

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 Short-Term Bond Fund is measured against the Lehman
Brothers 1 to 3 Year Government Index, an unmanaged index comprised of US
Government and agency securities with maturities of one to three years.
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 Short US Government Bond Funds Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the six months ended June 30, 1999, One Group Intermediate Bond Fund I share
class posted a total return of -0.08%.(1) The Fund's one-year total return on I
shares as of June 30, 1999, was 3.97%. (For information on other share classes
and performance comparisons to indexes, please see page 9.)

HOW DID MARKET DEVELOPMENTS INFLUENCE PERFORMANCE?
The fixed income market experienced significant volatility during the past year.
The second half of 1998 saw interest rates moving steadily downward, with the
30-year Treasury yield reaching an all-time low. Concerns about emerging markets
and the stability of the financial markets spawned a "flight to quality" in the
Treasury market and led the Federal Reserve to cut interest rates three times.

But, as we moved into 1999, interest rates began moving upward as strong U.S.
economic growth, inflation fears and improvements abroad emerged. These events
eventually led the Fed to raise interest rates at the end of June.

The Fund's overweighted positions in high-quality mortgage-backed and
asset-backed securities led to underperformance during the "flight to quality,"
as Treasuries outperformed all other fixed income securities. Mortgage- and
asset-backed securities rebounded during the first calendar quarter of 1999,
only to once again fall behind Treasuries in the second quarter of 1999, as
liquidity concerns re-emerged.

HOW DID THE FUND'S YIELD CHANGE?
Overall, interest rates were higher for the period, which caused the Fund's
share price to decline. However, the Fund's yield more than compensated for the
price depreciation. The Fund's 30-day SEC yield (I share class) increased to
6.37% on June 30, 1999, from 6.14% on December 31, 1998, and 6.34% on June 30,
1998.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
We attempted to keep the Fund's duration close to that of the Lehman Brothers
Intermediate Government/ Corporate Bond Index, the Fund's benchmark index.
(Duration is a measure of a fund's sensitivity to interest rate changes. A
longer duration indicates greater sensitivity; a shorter duration indicates
less.) On June 30, 1999, the Fund's duration was 3.9 years, versus 3.5 years for
the index. This strategy helped the Fund's share price avoid any wide swings as
interest rates increased.

We also focused on maintaining a high credit-quality profile. In an effort to
capture yield advantages, we emphasized high-quality mortgage- and asset-backed
securities that we believed were undervalued and offered superior risk/reward
characteristics.

HOW WAS THE FUND STRUCTURED IN TERMS OF SECTORS AND QUALITY?*
On June 30, 1999, 24% of the Fund's assets were invested in U.S. Treasuries, 45%
were in mortgage-backed securities, 10% were in asset-backed securities, 12%
were in corporate bonds and 6% were in money market securities. Securities rated
"AAA" comprised 75% of the Fund.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

WHAT IS YOUR OUTLOOK FOR THE FUND?
While we think the bond market will remain volatile, our long-term view is
positive, and we believe that current yield levels are very compelling. We
expect the Fund to remain heavily overweighted in mortgage-backed bonds, as we
believe the sector as a whole and the Fund's particular holdings are still very
undervalued. Furthermore, we think that many of the Fund's mortgage securities
may perform well in different interest rate environments. The Fund also remains
overweighted in the asset-backed sector, which we think may outperform
Treasuries during the next year. Finally, we will continue to emphasize
higher-quality securities and attempt to keep the Fund's duration similar to
that of its benchmark.

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
Intermediate Bond Fund for the period prior to the commencement of operations of
the One Group Intermediate Bond 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. A
common trust fund is not registered under the Investment Company Act of 1940
("1940 Act") and, therefore, is 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 Intermediate Bond Fund is measured against the Lehman
Brothers Intermediate Government/Corporate Bond Index, an unmanaged index
comprised of US Government agency and Treasury securities and investment grade
corporate bonds. 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 Lipper Short Intermediate US Government Bond Funds Index consists of funds
that invest at least 65% of its assets in securities issued or guaranteed by the
U.S. government, its agencies, or its instrumentalities, with a dollar-weighted
average maturity of one to five years.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the six months ended June 30, 1999, One Group Bond Fund I share class posted
a total return of -0.87%.(1) For the year ended June 30, 1999, the Fund's total
return on I shares was 3.25%. (For information on other share classes and
performance comparisons to indexes, please see page 13.)

HOW DID MARKET DEVELOPMENTS INFLUENCE PERFORMANCE?
The fixed income market experienced significant volatility over the past year.
The second half of 1998 saw interest rates moving steadily downward, with the
30-year Treasury yield reaching an all-time low. Concerns about emerging markets
and the stability of the financial markets spawned a "flight to quality" in the
Treasury market and led the Federal Reserve to cut interest rates three times.

But, as we moved into 1999, interest rates began moving upward as strong U.S.
economic growth, inflation fears and improvements abroad emerged. These events
eventually led the Fed to raise interest rates at the end of June.

The Fund's overweighted positions in high quality mortgage-backed and
asset-backed securities led to underperformance during the "flight to quality,"
as Treasuries outperformed all other fixed income securities. Mortgage- and
asset-backed securities rebounded during the first calendar quarter of 1999,
only to once again fall behind Treasuries in the second quarter of 1999, as
liquidity concerns re-emerged.

HOW DID THE FUND'S YIELD CHANGE?
Overall, interest rates were higher for the period, which caused the Fund's
share price to decline. However, the Fund's yield more than compensated for the
price depreciation. The Fund's 30-day SEC yield (I share class) increased to
7.06% on June 30, 1999, from 6.21% on December 31, 1998, and 6.30% on June 30,
1998.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
We attempted to keep the Fund's duration close to that of the Lehman Brothers
Aggregate Bond Index, the Fund's benchmark index. (Duration is a measure of a
fund's sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) On June 30, 1999, the Fund's
duration was 5.2 years, versus 4.9 years for the index. This strategy helped the
Fund's share price avoid any wide swings as interest rates fluctuated.

We also focused on maintaining a high credit-quality profile. In an effort to
capture yield advantages, we emphasized high quality mortgage- and asset-backed
securities that we believed were undervalued and offered superior risk/reward
characteristics.

HOW WAS THE FUND STRUCTURED IN TERMS OF SECTORS AND QUALITY?*
At the end of the six-month period, 31% of the Fund's assets were invested in
U.S. Treasuries, 51% were in mortgage-backed securities, 6% were in asset-backed
securities, 5% were in corporate bonds and 6% were in money market securities.
Securities rated "AAA" comprised 95% of the Fund.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

WHAT IS YOUR OUTLOOK FOR THE FUND?
While we think the bond market will remain volatile, our long-term view is
positive, and we believe that current yield levels are very compelling. We
expect the Fund to remain heavily overweighted in mortgage-backed bonds, as we
believe the sector as a whole and the Fund's particular holdings are still very
undervalued. Furthermore, we think that many of the Fund's mortgage securities
may perform well in different interest-rate environments. The Fund also remains
overweighted in the asset-backed sector, which we think may outperform
Treasuries during the next year. Finally, we will continue to emphasize
higher-quality securities and attempt to keep the Fund's duration similar to
that of its benchmark.

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 Bond
Fund for the period prior to the commencement of operations of the One Group
Bond 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. A
common trust fund is not registered under the Investment Company Act of 1940
("1940 Act") and, therefore, is 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 Bond Fund is measured against the Lehman Brothers
Aggregate Bond Index, an unmanaged index generally representative of the bond
markets as a whole. 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 Lipper Intermediate US Government Bond Funds Index consists of the equally
weighted average monthly return of the largest funds within the universe of all
funds in the category.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
One Group Income Bond Fund I share class offered a total return of -1.68% for
the six months ended June 30, 1999.(1) The Fund's total return on I shares for
the year ended June 30, 1999, was 1.94%. (For information on other share classes
and performance comparisons to indexes, please see page 16.)

A general climate of higher interest rates and wider yield spreads led to price
depreciation for the Fund. (Yield spreads refer to the difference in yield
between non-Treasury securities, such as agency, corporate and mortgage-backed
bonds, and comparable-maturity Treasury bonds. When spreads widen, prices on
non-Treasury bonds decline, and vice versa.) However, the Fund's yield increased
over the period due to higher interest rates, wider spreads and an increased
allocation to non-Treasury securities. The Fund's 30-day SEC yield on June 30,
1999, was 5.88%, compared to 5.41% on December 31, 1998, and 5.55% on June 30,
1998 (I share class).

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
As is consistent with our investment philosophy, our strategy was to search for
value across all sectors of the fixed income market. In determining value, we
conducted thorough credit analysis and comprehensive risk and return
evaluations. We increased the portfolio's allocations to Treasuries, agencies
and mortgage-backed securities and decreased allocations to corporate bonds and
asset-backed securities.

In addition to improving the Fund's yield, this action increased the average
quality of the Fund. As of June 30, 1999, 64% of the portfolio was invested in
AAA-rated securities, 7% in AA-rated, 18% in A-rated and 9% in BBB-rated. This
compares to 68% in AAA-rated, 13% in AA-rated, 16% in A-rated and 2% in
BBB-rated as of December 31, 1998, and 46% in AAA-rated, 23% in AA-rated, 25% in
A-rated and 4% in BBB-rated as of June 30, 1998.*

Duration management also played a role in generating return and controlling
risk. (Duration is a measure of a fund's sensitivity to interest rate changes. A
longer duration indicates greater sensitivity; a shorter duration indicates
less.) The Lehman Aggregate Bond Index replaced the Lehman Government/Corporate
Bond Index as the Fund's benchmark. As a result, the Fund's duration ended the
period at 4.7 years, compared to 5.4 years on December 31, 1998.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Much of the Fund's performance -- and that of all domestic fixed income
portfolios -- is contingent on economic activity. If the economy moderates from
its current rapid growth pace, yields likely will decline, resulting in an
increase in bond prices and in the Fund's share price. If the economy continues
to show strength and yields increase, bond prices and the Fund's share price
likely will decline.

(1) The Pegasus Multi Sector Bond Fund merged with the One Group Income Bond
    Fund on March 22, 1999. For financial reporting purposes, the Pegasus fund
    was considered the accounting survivor. Therefore, prior to the merger date
    of March 22, 1999 all financial statement and performance information for
    the One Group Income Bond Fund reflect that of the Pegasus fund. The Pegasus
    Funds previously had a fiscal year end of December 31. Subsequent to the
    merger, the fiscal year end changed from December 31 to June 30. See notes
    to financial statements for additional information.

* The Fund's composition is subject to change.

Please refer to the prospectus and the accompanying financial statements for
more information about the Fund.

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 Multi
Sector Bond Fund for the period prior to the commencement of operations of the
One Group Income Bond Fund on March 22, 1999. On December 2, 1994 the fund
terminated its offering of Class B shares and such shares converted to Class A
shares. The Fund re-offered Class B shares on May 31, 1994. Therefore, the
above-quoted performance data for Class B includes the performance of the
Pegasus Multi Sector Bond Fund for Class A for the period between December 2,
1994 to May 30, 1995. Performance for the Class B Shares is based on Class A
Share performance adjusted to reflect the absence of sales charges.

The performance of the Income Bond Fund is measured against the Lehman Brothers
Aggregate Bond Index, an unmanaged index comprised of US Government, mortgage,
corporate and asset-backed securities. 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 Lehman Brothers Government/Corporate Bond Index is an unmanaged index
generally representative of the government and corporate bond market as a whole.

The Lipper Intermediate Investment Grade Bond Funds Index consists of the
equally weighted average monthly return of the largest funds within the universe
of all funds in the category.

The benchmark index for the One Group Income Bond Fund has changed from the
Lehman Brothers Government/Corporate Bond Index to the Lehman Brothers Aggregate
Bond Index to better represent the investment policies for comparison purposes.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?

For the year ended June 30, 1999, One Group Government Bond Fund I share class
offered a total return of 1.94%. (For information on other share classes and
performance comparisons to indexes, please see page 19.)

HOW WOULD YOU DESCRIBE FISCAL 1999'S MARKET CLIMATE?

The fiscal year ending June 30, 1999, can be characterized as an incredibly
turbulent period in the fixed income market. In the fall of 1998, interest rates
hit new lows in the wake of emerging market and hedge fund crises. Concerns over
the stability of the financial markets caused the Federal Reserve to cut rates
three times during the second half of 1998. While interest rates were falling,
interest rate volatility and credit quality spreads were rising to levels not
seen in nearly a decade. (Spreads refer to the difference in yield between
non-Treasury securities, such as agency, corporate and mortgage-backed bonds,
and comparable-maturity Treasury bonds. When spreads widen, prices on
non-Treasury bonds decline, and vice versa.) To compound the problem, the low
interest rates led to significant mortgage refinancing activity, putting further
negative pressure on mortgage-backed securities.

As the fiscal year progressed, interest rates started showing an upward trend.
In addition, liquidity improved and spreads began to tighten. Mortgage-backed
bonds, highly rated corporate bonds and asset-backed securities outperformed
Treasuries in the first quarter of 1999. Economic indicators began to show that
the economy had not been negatively affected by the liquidity crisis in the
fall.

The final quarter of the fiscal year proved to the markets that the volatility
and liquidity problems of 1998 had not been completely erased. As the U.S.
economy continued growing at a rapid pace, the Fed took action with an interest
rate increase at the end of June. In anticipation of this move, interest rate
volatility surged and quality spreads again widened.

HOW DID THESE EVENTS INFLUENCE THE FUND?
Throughout the year we maintained investments in U.S. Treasuries, agency
securities and agency-issued mortgage-backed securities, with an emphasis on
mortgage-backed securities. In general, long-term Treasuries outperformed most
other sectors. The demand for liquidity, as well as a flattening of the yield
curve, significantly benefited these securities.

The significant rise in quality spreads, particularly those of mortgage-backed
securities, caused bond prices to decline, which negatively affected the Fund's
performance. These quality spreads have yet to recover. In addition, the
effective duration of the Fund was slightly longer that its 5.0 year target,
which negatively affected the Fund's price performance as interest rates
increased. (Duration is a measure of a fund's sensitivity to interest rate
changes. A longer duration indicates greater sensitivity; a shorter duration
indicates less.)

Overall, though, the Fund's performance was solid relative to the year's market
conditions. The one-year return was respectable given the high volatility in
interest rates and quality spreads and despite a period characterized by a very
flat -- and, at times, inverted -- yield curve.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our efforts were concentrated in maintaining a high quality and liquid portfolio
and keeping the Fund's duration close to our target of 5.0 years. The Fund's
duration varied during the year from 4.85 years to 5.40 years. This fluctuation
was due in part to the varying duration of mortgage-backed securities and the
increased interest rate volatility.

WHAT IS YOUR OUTLOOK FOR THE FUND?
In the short term, given the uncertainty surrounding inflation, economic growth
and Federal Reserve policy, we expect rates and spreads to remain volatile.
Later in the year, we believe the economy may start showing signs of a slowdown,
which should alleviate any additional pressure on the Fed to continue raising
rates. By year end, we expect interest rates to stabilize or moderately decline.
We also expect the yield curve to remain flat and overall interest rate
volatility to subside by year end. As such, the spread sectors, including agency
securities and agency-issued mortgages, may perform very well throughout the
rest of the calendar year. We plan to continue emphasizing these securities over
Treasuries.

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 Government Bond Fund is measured against the Salomon
Brothers 3 to 7 Year Treasury Index, an unmanaged index comprised of US
Government agency and Treasury securities and agency mortgage-backed securities.
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 Lipper US Government Bond Funds Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 1999

HOW DID THE FUND PERFORM?
For the year ended June 30, 1999, One Group Treasury & Agency Fund I share class
returned 3.54%. (For information on other share classes and performance
comparisons to indexes, please see page 22.)

The Fund's share price fluctuated throughout the year, as bond prices shifted in
response to perceived strength in the economy. In the fall of 1998, the market
perceived the U.S. economy would be negatively affected by the global economic
slowdown and therefore drove market yields down and bond prices up. Later, in
the first half of 1999, the U.S. economy showed more strength than had been
expected, resulting in higher market yields and lower bond prices.

Overall, for the period, yields increased and bond prices decreased. The Fund's
share price declined by approximately 2.78%, and the Fund's 30-day SEC yield
increased from 5.37% on June 30, 1998, to 5.99% on June 30, 1999 (I share
class).

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary investment strategy during the fiscal year involved adjusting the
portfolio's allocation to favor agency securities over Treasuries. In the fall
of 1998, the global economic crisis spawned a "flight to quality," which sparked
a strong rally in the Treasury market -- a rally from which the Fund's
performance benefited.

But, later in 1998, after the crisis subsided, we surmised that agency
securities would become a progressively better relative value than Treasury
securities. As such, we increased the Fund's allocation to agencies. This proved
to be an effective strategy, as the agency securities contributed higher yield
and greater return potential to the portfolio.

Our ongoing strategy of maintaining a neutral duration of 2.9 years helped the
Fund avoid any negative performance due to poorly implemented market timing.
(Duration is a measure of a fund's sensitivity to interest rate changes. A
longer duration indicates greater sensitivity; a shorter duration indicates
less.) The Fund's duration did fluctuate -- from 2.72 years to 3.22
years -- during the 12-month period, but that was due to the varying duration of
callable agency bonds. (The call feature refers to the bond issuer's right to
repay, or "call," the bond before the scheduled maturity date. Securities that
have this feature typically offer higher yields in return for the call risk.) As
yields decreased, the higher probability of being called resulted in shorter
duration, and as yields increased, the lower probability of being called
resulted in a longer duration.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Economic activity will play a significant role in the Fund's performance during
the next year. If the economy moderates from its current rapid pace of growth,
yields likely will decline, and we would expect bond prices and the Fund's share
price to increase. If the economy continues to show strength and yields
increase, we would expect bond prices and the Fund's share price to decline.

As we begin fiscal 2000, we are taking advantage of opportunities in the
government bond market. From a historical perspective, agency yields currently
are very attractive relative to Treasuries, and the portfolio's agency component
is fully allocated. In the Treasury component, we are focusing on select
seasoned Treasuries that offer a yield advantage and higher total return
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.

The above-quoted performance data includes the performance of a collective trust
fund for the period prior to the commencement of operations of the mutual fund
on January 20, 1997, adjusted to reflect the deduction of fees and expenses. The
collective trust fund was not registered under the Investment Company Act of
1940 ("1940 Act") and, therefore, was not subject to certain investment
restrictions, limitations and diversification requirements imposed by the 1940
Act and the Internal Revenue Code. If the collective trust fund had been
registered under the 1940 Act, its performance may have been adversely affected.

The performance of the Treasury & Agency Fund is measured against the Lehman
Brothers Intermediate Treasury Index, an unmanaged index comprised of US
Treasury-issued securities with maturities of one to ten years. 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 Mix for all the classes consists of the average monthly returns of
the Lipper Intermediate Treasury Bond Funds Index from April 1988 through
December 1989. Thereafter, the data is from the Lipper Short US Government Bond
Funds Index which corresponds with the initiation of the Index on January 1,
1989. The Lipper Indices consist of the equally weighted average monthly return
of the largest funds within the universe of all funds in the category.

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

HOW DID THE FUND PERFORM?
One Group High Yield Bond Fund I share class posted a total return of 3.80% for
the period from the Fund's inception on November 13, 1998, through June 30,
1999. (For information about other share classes and performance comparisons to
indexes, please see page 25.)

The Fund benefited from commencing operations during the beginning of a recovery
period in the high-yield bond market. Prior to that, the market suffered from
the global liquidity crisis that emerged in the summer of 1998. The market began
to recover later in the year after the Federal Reserve intervened with three
interest rate cuts. In the first six months of 1999 interest rates began to
climb, which caused bond prices to decline. However, spreads tightened during
the same time period, buffering the negative pressure of rising interest rates.
(Spreads refer to the difference in yield between non-Treasury bonds -- in this
case high-yield bonds -- and comparable-maturity Treasury bonds.) High-yield
spreads generally tighten when interest rates rise and widen when interest rates
fall. This tightening of spreads was the prime reason high-yield bonds
outperformed most other intermediate fixed income categories during the period.

DID THE FUND'S YIELD BENEFIT FROM THE RISING RATE ENVIRONMENT?
As a fixed income investment, high-yield bonds are influenced by interest rate
movements, but their higher average coupon does insulate them from rising
interest rates more than most other intermediate fixed income securities. The
Fund's SEC yield did increase throughout the period -- to 9.09% on June 30,
1999 -- primarily due to the Fund becoming nearly fully invested in high-yield
bonds, with less exposure to commercial paper and other short-term instruments.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our overall strategy is to maintain a well-diversified portfolio across issuers
and industries. The most important component of this strategy is to understand
the unique, fundamental characteristics of the companies we invest in. As such,
we rely on our analyst team's bottom-up credit research expertise along with the
portfolio manager's top-down perspective on the market as a whole.

We maintained the Fund's duration in a fairly tight band throughout the period.
(Duration is a measure of a fund's price sensitivity to interest rate changes. A
higher duration indicates greater sensitivity; a shorter duration indicates
less.) The Fund's duration ranged from 4.84 years to 5.04 years and ended the
period at 4.97 years.

The Fund benefited from our decisions to underweight the health care and energy
sectors, which underperformed, and to overweight telecommunications and
media-related sectors, which, on a fiscal year-to-date basis, offered solid
performance.

HOW DID YOU MANAGE THE FUND'S CREDIT QUALITY?
One of the critical elements of successfully managing high-yield bond portfolios
is to avoid rapidly deteriorating credits or to sell them before they
significantly decline. Our analysts attempt to do this by closely studying and
monitoring every security the Fund owns in order to stay ahead of the market.
Our portfolio managers closely follows the trading of every security in the Fund
to spot market clues to potential deterioration of individual companies or
industry sectors.

As of June 30, 1999, securities rated "BBB" or better comprised 0.2% of the
Fund, while those rated "BB" comprised 12.2%, "B," 75.0%, and "CCC," 7.5%.
Unrated companies comprised 5.1% of the Fund. The remainder was invested in cash
or cash equivalents.

WHAT IS YOUR OUTLOOK FOR THE FUND?
If the economy stays strong, which we think it should, high-yield bonds should
continue to do well. We expect this environment to be favorable for corporate
credit quality to remain stable or improve. Even if interest rates continue to
rise, as long as corporations and consumers have reasonable access to capital,
it's likely that high-yield bonds will outperform other fixed income
alternatives. However, it's important to remember that the primary emphasis of
the Fund is managing and maintaining credit quality, not anticipating or
responding to interest rate movements.

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 High Yield Bond Fund is measured against the Credit
Suisse First Boston High Yield Bond Index, an unmanaged index comprised of
securities that are selected primarily on the basis of size, liquidity and
diversification to be representative of the high yield bond 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.

(b) A portion of this security was loaned as of June 30,1999.

(c) The Fund invests in securities whose value is derived from an underlying
    pool of mortgages or consumer loans. Descriptions of certain collateralized
    mortgage obligations are as follows:

    Collateralized Mortgage Obligations (CMO) are debt securities issued by U.S.
    government agencies, or by financial institutions and other mortgage
    lenders, which are collateralized by a pool of mortgages held under an
    indenture.

    Interest Only (IO) represents the right to receive the monthly interest
    payment on an underlying pool of mortgage loans. The face amount shown
    represents the par value on the underlying pool. The yields on these
    securities are generally higher than prevailing market yields on other
    mortgage-backed securities because their cash flow patterns are more
    volatile and there is a greater risk that the initial investment will not be
    fully recouped. These securities are subject to accelerated principal
    paydowns as a result of prepayment or refinancing of the underlying pool of
    mortgage instruments. As a result, interest income may be reduced
    considerably.

    Principal Only (PO) represents the right to receive the principal portion
    only on an underlying pool of mortgage loans. The market value of these
    securities is extremely volatile in response to changes in market interest
    rates. As prepayments on the underlying mortgages of these securities
    increase, the yield on these securities increases.

 *  The interest rate for this variable rate note, which will change
    periodically, is based upon an index of market rates. The rate reflected on
    the Schedule of Portfolio Investments is the rate in effect at June 30,
    1999.

See notes to financial statements.

(b) A portion of this security was loaned as of June 30, 1999.

(c) Amount is less than 1000.

(d) The Fund invests in securities whose value is derived from an underlying
    pool of mortgages or consumer loans. Descriptions of certain collateralized
    mortgage obligations are as follows:

    Collateralized Mortgage Obligations (CMO) are debt securities issued by U.S.
    government agencies, or by financial institutions and other mortgage
    lenders, which are collateralized by a pool of mortgages held under an
    indenture.

    Inverse Floaters (IF) represent securities that pay interest at a rate that
    increases (decreases) with a decline (increase) in a specified index.

    Interest Only (IO) represents the right to receive the monthly interest
    payment on an underlying pool of mortgage loans. The face amount shown
    represents the par value on the underlying pool. The yields on these
    securities are generally higher than prevailing market yields on other
    mortgage-backed securities because their cash flow patterns are more
    volatile and there is a greater risk that the initial investment will not be
    fully recouped. These securities are subject to accelerated principal
    paydowns as a result of prepayment or refinancing of the underlying pool of
    mortgage instruments. As a result, interest income may be reduced
    considerably.

(Amounts in thousands)

    High Coupon Bonds (HB) (a.k.a "IOettes") represent the right to receive
    interest payments on an underlying pool of mortgages with similar risks as
    those associated with IO securities. Unlike IO's the owner also has a right
    to receive a very small portion of principal. The high interest rate results
    from taking interest payments from other classes in the REMIC trust and
    allocating them to the small principal of the HB class.

    Principal Only (PO) represents the right to receive the principal portion
    only on an underlying pool of mortgage loans. The market value of these
    securities is extremely volatile in response to changes in market interest
    rates. As prepayments on the underlying mortgages of these securities
    increase, the yield on these securities increases.

(e) Security exempt from registration under Rule 144A of the Securities Act of
    1933. These securities may be resold in transactions exempt from
    registration, normally to qualified institutional buyers. These securities
    amounted to $28,433 or 1.82% of net assets.

*   The interest rate, for this variable rate note, which will change
    periodically, is based upon prime rates or an index of market rates. The
    rate reflected on the Schedule of Portfolio of Investments is the rate in
    effect as of June 30, 1999.

(b) A portion of this security was loaned as of June 30, 1999.

(c) The Fund invests in securities whose value is derived from an underlying
    pool of mortgages or consumer loans. Descriptions of certain collateralized
    mortgage obligations are as follows:

    Collateralized Mortgage Obligations (CMO) are debt securities issued by U.S.
    government agencies, or by financial institutions and other mortgage
    lenders, which are collateralized by a pool of mortgages held under an
    indenture.

    Inverse Floaters (IF) represent securities that pay interest at a rate that
    increases (decreases) with a decline (increase) in a specified index.

    Interest Only (IO) represents the right to receive the monthly interest
    payment on an underlying pool of mortgage loans. The face amount shown
    represents the par value on the underlying pool. The yields on these
    securities are generally higher than prevailing market yields on other
    mortgage-backed securities because their cash flow patterns are more
    volatile and there is a greater risk that the initial investment will not be
    fully recouped. These securities are subject to accelerated principal
    paydowns as a result of prepayment or refinancing of the underlying pool of
    mortgage instruments. As a result, interest income may be reduced
    considerably.

(Amounts in thousands)

    High Coupon Bonds (HB) (a.k.a "IOettes") represent the right to receive
    interest payments on an underlying pool of mortgages with similar risks as
    those associated with IO securities. Unlike IOs the owner also has a right
    to receive a very small portion of principal. The high interest rate results
    from taking interest payments from other classes in the REMIC trust and
    allocating them to the small principal of the HB class.

    Principal Only (PO) represents the right to receive the principal portion
    only on an underlying pool of mortgage loans. The market value of these
    securities is extremely volatile in response to changes in market interest
    rates. As prepayments on the underlying mortgages of these securities
    increase, the yield on these securities increases.
*   The interest rate for these bonds changes periodically based on an
    underlying benchmark (ie PRIME, LIBOR, etc). The rate reflected in the
    Schedule of Portfolio Investments is the rate in effect as of June 30, 1999.

(b) A portion of this security was loaned as of June 30, 1999.

(c) Security exempt from registration under Rule 144A of the Securities Act of
    1933. These securities may be resold in transactions exempt from
    registration, normally to qualified institutional buyers. These securities
    amounted to $6,249 or .45% of net assets.

(d) The Fund invests in securities whose value is derived from an underlying
    pool of mortgages or consumer loans. Descriptions of certain collateralized
    mortgage obligations are as follows:

    Collateralized Mortgage Obligations (CMO) are debt securities issued by U.S.
    government agencies, or by financial institutions and other mortgage
    lenders, which are collateralized by a pool of mortgages held under an
    indenture.

    Interest Only (IO) represents the right to receive the monthly interest
    payment on an underlying pool of mortgage loans. The face amount shown
    represents the par value on the underlying pool. The yields on these
    securities are generally higher than prevailing market yields on other
    mortgage-backed securities because their cash flow patterns are more
    volatile and there is a greater risk that the initial investment will not be
    fully recouped. These securities are subject to accelerated principal
    paydowns as a result of prepayment or refinancing of the underlying pool of
    mortgage instruments. As a result, interest income may be reduced
    considerably.

    Principal Only (PO) represents the right to receive the principal portion
    only on an underlying pool of mortgage loans. The market value of these
    securities is extremely volatile in response to changes in market interest
    rates. As prepayments on the underlying mortgages of these securities
    increase, the yield on these securities increases.

*  The interest rate for this variable rate note, which will change
   periodically, is based upon an index of market rates. The rate reflected on
   the Schedule of Portfolio Investments is the rate in effect at June 30, 1999.

See notes to financial statements.

NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 1999

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 Ultra
   Short-Term Bond Fund (previously the Ultra Short-Term Income Fund),
   Short-Term Bond Fund (previously the Limited Volatility Bond Fund),
   Intermediate Bond Fund (previously the Pegasus Intermediate Bond Fund), Bond
   Fund (previously the Pegasus Bond Fund), Income Bond Fund (previously the
   Pegasus Multi Sector Bond Fund), Government Bond Fund, Treasury & Agency
   Fund, and High Yield Bond 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. For
   financial reporting purposes, the Pegasus Intermediate Bond Fund and Pegasus
   Multi Sector Bond Fund are considered the accounting survivors. Therefore,
   prior to March 22, 1999 all financial statement and performance information
   for the One Group Intermediate Bond Fund and One Group Income Bond Fund
   reflect that of the Pegasus Intermediate Bond Fund and Pegasus Multi Sector
   Bond Fund, respectively. Subsequent to the reorganization, the fiscal year
   end changed from December 31 to June 30 for the Intermediate Bond Fund, the
   Bond Fund and the Income Bond 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. All financial information for the periods
   prior to March 22, 1999 represent the predecessor fund.

   The Funds' investment objectives are as follows:

      Ultra Short-Term Bond Fund              Seeks a high level of current income consistent with low
                                               volatility of principal by investing in a diversified
                                               portfolio of short-term investment grade securities.

      Short -Term Bond Fund                   Seeks current income consistent with the preservation of

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

     Debt securities (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 an 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.

     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 by a fund under the 1940 Act.

     WRITTEN OPTIONS

     The Funds (except for the Treasury & Agency Fund) 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. Premi-

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

     INDEXED SECURITIES

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

     MORTGAGE ROLLS

     The Funds may enter into mortgage "dollar rolls" in which the Fund sells
     mortgage-backed securities for delivery in the current month and
     simultaneously contracts to repurchase substantially similar securities on
     a specified future date. During the roll period, the Fund forgoes principal
     and interest paid on the mortgage-backed securities. The Fund is
     compensated by fee income or the difference between the current sales price
     and the lower forward price for the future purchase.

     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 interest on securities lent while simultaneously seeking
     to earn interest on the investment of cash collateral. Collateral is marked
     to market daily to provide a level of collateral at least equal to the
     market value of securities lent. There may be risks of delay in recovery of
     the securities or even loss of rights in the collateral should the borrower
     of the securities fail financially. However, loans will be made only to
     borrowers deemed by the Advisor to be of good standing and creditworthy
     under guidelines established by the Board of Trustees and when, in the
     judgment of the Advisor, the consideration which can be earned currently
     from such securities loans justifies the attendant risks. Loans are subject
     to termination by the Funds or the borrower at any time, and are,
     therefore,

</TABLE>

     The loaned securities were fully collateralized by cash, U.S. Government
     securities, 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 daily and paid monthly
     for the Funds. 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 mortgage-backed securities, expiring
     capital loss carryforwards, and deferrals of certain losses. Permanent book
     and tax basis differences have been reclassified among the components of
     net assets.

     ORGANIZATION COSTS

     Costs incurred by the Trust in connection with its organization, including
     the fees and expenses of registering and qualifying its shares for
     distribution have been deferred and are being amortized using the
     straight-line method over a period of five years beginning with the
     commencement of each Fund's operations. All such costs, which are
     attributable to more than one fund of the Trust, have been allocated among
     the respective

     funds pro-rata, based on the relative net assets of each Fund. In the event
     that any of the initial shares are redeemed during such period by any
     holder thereof, the related fund will be reimbursed by such holder for any
     unamortized organization costs in the proportion as the number of initial
     shares being redeemed bears to the number of initial shares outstanding at
     the time of redemption.

     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.

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
   the 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 funds' prospectus. Certain
   redemptions of Class B and Class C shares are subject to contingent deferred
   sales charges in accordance with the funds' prospectus. As of June 30, 1999,
   no shareholders were in Class C of the funds except for the Intermediate Bond
   Fund, the Bond Fund, the Government Bond Fund and the High Yield Bond 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 Trust and the Advisor are parties to an investment advisory agreement
   under which the Advisor is entitled to receive an annual fee, computed daily
   and paid monthly, equal to the following percentages of the Funds' average
   net assets: 0.55% of the Ultra Short-Term Bond Fund, 0.60% of the Short-Term
   Bond Fund, the Intermediate Bond Fund, the Income Bond Fund and the Bond
   Fund; 0.45% of the Government Bond Fund; 0.40% of the Treasury & Agency Fund;
   and 0.75% of the High Yield Bond Fund.

   Prior to March 22, 1999, the Trust and First Chicago NBD Investment
   Management Company ("FCNIMCO") were parties to an investment advisory
   agreement under which the Advisor was entitled to a fee, computed daily and
   paid monthly, at an annual rate of 0.40% of the average net assets of the
   Intermediate Bond Fund, the Bond Fund and the Income Bond Fund.

   The Trust and the Administrator, a wholly-owned subsidiary of The BISYS
   Group, Inc., are parties to an administrative agreement under which the
   Administrator provides services for a fee that is computed daily and paid
   monthly, at an annual rate of 0.20% on the first $1.5 billion of Trust net

   the Administrator and the Advisor. Pursuant to this agreement, the Advisor
   performs many of the Administrator's duties, for which the Advisor receives a
   fee paid by the Administrator.

   Prior to March 22, 1999 FCNIMCO and BISYS Fund Service (the
   "Co-Administrators") were parties to a Co-Administration Agreement under
   which the Co-Administrators were entitled to a fee, computed daily and paid
   monthly, at an annual rate of 0.15% of the average net assets of the
   Intermediate Bond Fund, the Bond Fund and the Income Bond Fund.

6. FINANCIAL INSTRUMENTS:

   Investing in financial instruments such as written options, futures,
   structured notes and indexed securities involves risks in excess of the
   amounts reflected in the Statements of Assets and Liabilities. The face or
   contract amounts reflect the extent of the involvement the Funds have in the
   particular class of instrument. Risks associated with these instruments
   include an imperfect correlation between the movements in the price of the
   instruments and the price of the underlying securities and interest rates, an
   illiquid secondary market for the instruments or inability of counterparties
   to perform under the terms of the contract. The Funds enter into these

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 Ultra Short-Term Bond Fund, the Short-Term Bond Fund (formerly the Limited
Volatility Bond Fund), the Intermediate Bond Fund, the Bond Fund (formerly the
Pegasus Bond Fund), the Income Bond Fund, the Government Bond Fund, the Treasury
& Agency Fund, and the High Yield Bond Fund (eight 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, and the cash flows of the
Short-Term Bond Fund, the Intermediate Bond Fund, the Bond Fund and the Income
Bond Fund for each of the periods 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 Intermediate Bond Fund, the Bond Fund and the Income
Bond 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.
