HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Ultra Short-Term Bond Fund I share
class posted a total return of 5.66%. (For information on other share classes
and performance comparisons to indexes, please see page 4.)

HOW WOULD YOU DESCRIBE THE YEAR'S MARKET CLIMATE?
The 12-month period was characterized by rising interest rates, as the U.S.
economy continued to surprise investors with high growth and low inflation.
Uncomfortable with this situation, the Federal Reserve embarked on a
rate-tightening campaign that eventually raised the federal funds rate by 1.75
percentage points. More important, short-term market rates increased by more
than 1 percentage point.

High levels of spread volatility characterized the performance of the
mortgage-backed sector during the year. (Spreads refer to the differences in
yields between non-Treasury bonds, such as agency, corporate and mortgage-backed
securities, and comparable-maturity Treasury bonds. When spreads widen, prices
on non-Treasury bonds decline, and vice versa.) At the beginning of the fiscal
year, increasing concerns over potential Federal Reserve tightening and Y2K
caused interest rate volatility to spike, and spreads on mortgage-backed
securities widened. But, after the Federal Reserve announced it would provide
enough liquidity to combat any Y2K problems, spreads tightened.

During the first quarter of 2000, strong global growth, a soaring equity market
and high levels of non-public debt led to concerns that the Federal Reserve
would become significantly more restrictive. In addition, record U.S. government
surpluses led the U.S. Treasury to implement a buyback program of federal debt.
These factors resulted in an inversion of the yield curve, and spreads re-tested
their historical highs. Furthermore, the high levels of growth in some
government agencies, particularly Freddie Mac and Fannie Mae, have come under
Congressional scrutiny. We do not expect any changes in the legal or credit
status of these agencies, but spreads on their debt have risen significantly.
Also, this event has led to a dislocation in the mortgage market, where the
value of Ginnie Mae securities has risen significantly in relation to those of
Fannie Mae and Freddie Mac.

HOW DID THESE EVENTS INFLUENCE THE FUND?
The significant widening of spreads, particularly among mortgage-related
securities, negatively affected the Fund's performance. In addition, the Federal
Reserve's tightening of monetary policy negatively influenced performance by
increasing the level of spread volatility and the overall level of interest
rates.

At the same time, the rise in short-term interest rates led to increases in the
coupon rates of the Fund's floating-rate securities, which enhanced Fund
performance. Coupon income was the key to performance for the year. The rising
rate environment caused the Fund's share price to decline, but the level of
income more than offset the share price depreciation, resulting in a positive
total return.

Rising interest rates also helped push up the Fund's yield. As of June 30, 2000,
the Fund's 30-day SEC yield on I shares was 6.61%, compared to 5.35% on June 30,
1999.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our strategy is to attempt to maximize total return while maintaining a
relatively stable net asset value. As such, we invest primarily in high-quality
fixed and floating-rate asset-backed and mortgage-backed securities that offer
significant yield advantages over comparable-maturity Treasury securities.

We also attempt to keep the Fund's duration close to its target of 0.9 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.) Duration fluctuated from 0.95 years to 1.10 years, primarily due to the
varying duration of mortgage-backed securities and the increased interest rate
volatility. At fiscal year-end, duration was 1.03 years.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Given the uncertainty surrounding inflation, economic growth and Federal Reserve
policy, we expect rates and spreads to remain volatile for the near term. But,
we believe the economy will start slowing down in the fall, and this should put
an end to the Federal Reserve's

rate hikes. By the end of the year, we expect interest rates to remain steady or
even fall slightly. The yield curve should flatten, and overall interest rate
volatility should drop. As such, we expect spread securities to perform well
during the second half of 2000.

We plan to continue heavily overweighting spread securities. In addition, we
expect to maintain duration at or slightly above our target duration to keep
interest rate risk relatively neutral. Finally, we will actively pursue
opportunities to enhance the Fund's yield.

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 (ML) 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 fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Ultra Short Fund Index is typically comprised of the 30 largest
mutual funds that invest at least 65% of their assets in investment grade debt
issues, or better, and maintain a portfolio dollar-weighted average maturity
between 91 and 365 days.

The Lipper Ultra Short Fund Index consists of the average monthly returns of the
Lipper Adjustable Rate Mortgage Fund Index for periods prior to July 1996.
Thereafter, the data is from the Lipper Ultra Short Fund Index, which
corresponds with the initiation of the Lipper Ultra Short Fund Index on July 1,
1996.

(1) Class B shares automatically convert to Class A shares after six years.
    Therefore, the performance in the "since inception" example for Class B
    shares represents a combination of Class A and Class B operating expenses.

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

HOW DID THE FUND PERFORM?
For the 12-month period ended June 30, 2000, One Group Short-Term Bond Fund I
share class posted a total return of 4.81%. (For information on other share
classes and performance comparisons to indexes, please see page 6.)

The fiscal year ended June 30, 2000, can be characterized as an incredibly
turbulent period in the fixed income market. Interest rates increased across the
board, with shorter-term rates rising more than longer-term rates. Yield spreads
widened during the year, causing agency and other non-Treasury sectors to
underperform Treasury securities. (Spreads refer to the differences in yields
between non-Treasury bonds, such as agency, corporate, asset-backed and
mortgage-backed securities, and comparable-maturity Treasury bonds. When spreads
widen, prices on non-Treasury bonds decline, and vice versa.)

With yields higher across the entire yield curve, bond prices declined
throughout the fiscal year. But, the Fund's income was enough to offset the
price declines, resulting in a positive total return for the Fund.

HOW DID THE FUND'S YIELD CHANGE?
The Fund's yield increased throughout the year, due to the rising interest rate
environment. As of June 30, 2000, the Fund's 30-day SEC yield on I shares was
6.38%, compared to 5.66% on June 30, 1999.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Consistent with our investment philosophy, our strategy was to search for value
based on thorough credit research and risk/return analysis across all sectors of
the fixed income market. At the same time, we carefully controlled the Fund's
duration, or interest rate risk. These strategies helped reduce the negative
effects of last fiscal year's flight to quality on Fund performance.

In anticipation of higher interest rates, we lowered the Fund's duration to help
limit the impact of rising rates and falling prices. Duration ended the fiscal
year at 1.6 years, compared to 1.8 years on June 30, 1999. (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 Federal Reserve's interest rate hikes during the year helped the yield curve
take on an inverted shape, meaning that shorter-term bonds offered higher yields
than long-term bonds. Our barbelled strategy of investing in maturities at the
short and long ends of our maturity range helped mitigate the effects of rising
interest rates.

WHAT WAS THE FUND'S QUALITY PROFILE?*
In general, higher-quality securities performed better than lower-quality
securities during the year. We maintained a high-quality portfolio throughout
the period, and at fiscal year end, 82% of the Fund's assets was invested in
securities rated "AAA." Securities rated "AA" "A" and "BBB" comprised 2%, 15%
and 1% of the portfolio, respectively.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Our expectation is for interest rates to possibly head higher over the near
term, as the economy continues to grow at a solid rate. We believe the Federal
Reserve may continue to raise the federal funds rate this year, possibly peaking
at 7%. We believe the Federal Reserve remains committed to keeping inflation
under control and will successfully slow down the economy. This should
contribute to a positive bond market environment. Spreads may remain volatile
and wider than their historical averages due to supply and demand changes in the
market. Nonetheless, over time, we believe that non-Treasury securities will
continue to present attractive investment opportunities.

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 1-3 Year Government/Credit Bond Index, an unmanaged index with a broad
measure of the performance of short-term government and corporate fixed-rate
debt issues. Investors are unable to purchase the index directly, although they
can invest in the underlying securities. The performance of the index does not
reflect the deduction of expenses associated with a mutual fund, such as
investment management fees. By contrast, the performance of the Fund reflects
the deduction of these services as well as the deduction of sales charges on
Class A shares and applicable contingent deferred sales charges on Class B
shares.

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

The Lipper Short US Government Fund Index consists of the equally weighted
average monthly returns of the largest funds within the universe of all funds in
the category.

The benchmark index for the Short-Term Bond Fund has changed from the Lehman
Brothers 1-3 Year Government Index to the Lehman Brothers 1-3 Year
Government/Credit Index in order to better represent the investment policies for
comparison purposes.

(1) Class B shares automatically convert to Class A shares after six years.
    Therefore, the performance in the "since inception" example for Class B
    shares represents a combination of Class A and Class B operating expenses.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Intermediate Bond Fund I share class
posted a total return of 4.12%. (For information on other share classes and
performance comparisons to indexes, please see pages 8-9.)

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

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

HOW DID THE FUND'S YIELD CHANGE?
The rising interest rate environment caused bond prices to fall and the Fund's
net asset value to decrease slightly during the year. Rising rates also
contributed to a slight increase in the Fund's yield. As of June 30, 2000, the
Fund's 30-day SEC yield on I shares was 6.56%, compared to 6.37% on June 30,
1999.

WHAT WERE YOUR KEY STRATEGIES AND TACTICS?
In our efforts to outperform the Fund's benchmark index, the Lehman Intermediate
Government/Credit Bond Index, we kept the Fund's duration similar to that of the
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.) At the same time, we held more longer-duration securities and fewer short
and intermediate securities because we expected yield increases (and price
declines) to be more subdued among longer securities. We also overweighted
high-quality corporate, mortgage- and asset-backed securities because of their
significantly higher yields versus Treasuries.

Security selection also was a key component of our strategy throughout the year.
By carefully researching each security we considered for purchase, we were able
to enhance the Fund's total return without taking on additional incremental
risk.

HOW WAS THE FUND STRUCTURED IN TERMS OF SECTORS AND QUALITY?*
As of June 30, 2000, 48% of the Fund's assets were invested in mortgage-backed
securities; 24% were invested in U.S. Treasuries; 11% were invested in corporate
bonds; 9% were invested in money market securities and 8% were invested in
asset-backed securities. We maintained a high credit-quality profile throughout
the year, and securities rated "AAA" comprised 86% of the Fund on June 30, 2000.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Our expectation is for interest rates to possibly head higher over the near
term, as the economy continues to grow at a solid rate in the third quarter. We
believe the Federal Reserve may continue to raise the federal funds rate this
year, possibly until it reaches 7%. Longer term, we believe the Federal Reserve
will slow down the economy and remain committed to keeping inflation under
control. This should contribute to a positive bond market environment. Spreads
may remain volatile and wider than their historical averages due to supply and
demand changes in the market. Nonetheless, we believe that non-Treasury
securities will continue to present attractive investment opportunities over the
long 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 Intermediate Bond Fund commenced operations as the Pegasus Intermediate Bond
Fund on June 1, 1991, subsequent to the transfer of assets from a common trust
fund with materially equivalent investment objectives, policies, guidelines and
restrictions as the Fund. The quoted performance of the Fund includes the
performance of the common trust fund for periods prior to the Fund's
commencement of operations as adjusted to reflect the expenses and sales charges
associated with the Fund. Common trust funds are not registered under the
Investment Company Act of 1940 ("1940 Act") and, therefore, are not subject to
certain investment restrictions, limitations and diversification requirements
imposed by the 1940 Act and the Internal Revenue Code. If the common trust fund
had been registered under the 1940 Act, its performance may have been adversely
affected. The above quoted performance data includes the performance of a common
trust fund and the Pegasus Intermediate Bond Fund prior to the acquisition by
the One Group Intermediate Bond Fund on March 22, 1999.

The performance of the Intermediate Bond Fund is measured against the Lehman
Brothers Intermediate Government/Credit 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 fees. By contrast, the performance of the Fund reflects
the deduction of these services as well as the deduction of sales charges on
Class A shares and applicable contingent deferred sales charges on Class B and
Class C shares. The Lehman Brothers Intermediate Government/Credit Bond Index
was formally named the Lehman Brothers/Corporate Bond Index.

The Lipper Short Intermediate US Government Index consists of the equally
weighted average monthly returns of the largest funds within the universe of all
funds in the category.

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

HOW DID THE FUND PERFORM?
One Group Bond Fund I share class posted a total return of 3.94% for the year
ended June 30, 2000. (For information on other share classes and performance
comparisons to indexes, please see pages 11-12.) The Fund's 30-day SEC yield on
I shares ended the fiscal year at 6.74%.

During the fiscal year interest rates increased as the U.S. economy continued to
surprise investors with high levels of income growth and low inflation.
Uncomfortable with the strong economic growth and potential for future
inflation, the Federal Reserve began a series of interest rate hikes that
eventually pushed up the federal funds rate by 1.75 percentage points. But, more
important, short-term market rates rose by more than 1 percentage point.

In addition, spread volatility remained high during the year, and non-Treasury
securities underperformed. (Spreads refer to the differences in yields between
non-Treasury bonds, such as agency, corporate and mortgage-backed securities,
and comparable-maturity Treasury bonds. When spreads widen, prices on non-
Treasury bonds decline, and vice versa.) But, within the spread sectors,
higher-quality securities, such as those represented in the Fund, performed
better than lower-quality securities.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
In our goal of outperforming the Lehman Aggregate Bond Index, we kept the Fund's
average duration in line with that of the 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.) At the same time, we held more
longer-duration securities and fewer short and intermediate securities because
we expected yield increases (and price declines) to be less significant among
longer securities. We also overweighted high-quality corporate, mortgage- and
asset-backed securities because of the yield advantages these securities offered
versus Treasuries.

We also focused on security selection and carefully researched each bond we
purchased for the Fund. These efforts enabled us to enhance the Fund's total
return without taking on additional incremental risk.

HOW WAS THE FUND STRUCTURED IN TERMS OF SECTORS AND QUALITY?*
As of June 30, 2000, 53% of the Fund's assets was invested in mortgage-backed
securities; 28% was invested in U.S. Treasuries, 6% was in asset-backed
securities; 6% was in corporate bonds and 6% was in money market securities. We
maintained a high credit-quality profile throughout the year, and securities
rated "AAA" comprised 93% of the Fund on June 30, 2000.

WHAT IS YOUR OUTLOOK FOR THE FUND?
We expect interest rates to possibly head higher over the near term, as the
economy continues to grow in the months ahead. We believe additional Federal
Reserve rate hikes may be in store this year and expect the federal funds rate
to top out around 7%. Longer term, we believe the Federal Reserve will be
successful in slowing down the economy through its commitment to keeping
inflation under control. This should contribute to a positive bond market
environment. Supply and demand changes in the market may cause spreads to remain
volatile and wider than their historical averages, but we still believe that,
over time, non-Treasury securities will continue to present attractive
investment opportunities.

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

The performance of the Bond Fund is measured against the Lehman Brothers
Aggregate Bond Index, an unmanaged index generally representative of the bond
market as a whole. Investors are unable to purchase the index directly, although
they can invest in the underlying securities. The performance does not reflect
the deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B and Class C shares.

The Lipper Intermediate US Government Index consists of the equally weighted
average monthly returns of the largest funds within the universe of all funds in
the category.

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

HOW DID THE FUND PERFORM?
The One Group Income Bond Fund I share class posted a total return of 4.19% for
the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see pages 14-15.)

Rising interest rates and widening yield spreads had a negative effect on the
Fund's one-year total return. (Spreads refer to the differences in yields
between non-Treasury bonds, such as agency, corporate and mortgage-backed
securities, and comparable-maturity Treasury bonds. When spreads widen, prices
on non-Treasury bonds decline, and vice versa.) With yields generally higher
across the yield curve, bond prices declined. But the Fund's income level was
enough to offset the price declines, resulting in a positive total return.

HOW DID THE FUND'S YIELD CHANGE?
The Fund's yield increased throughout the year as a result of higher market
interest rates and the addition of a modest allocation to high-yield securities.
The Fund's 30-day SEC yield on I shares was 7.10% on June 30, 2000, compared to
5.88% on June 30, 1999.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our ongoing strategy is to search for and purchase undervalued securities and
market sectors. During the past fiscal year, the sectors that we believe
represented the best value included spread products in general and, more
specifically, mortgage-backed securities. As such, we increased the Fund's
allocations to mortgages and decreased its weightings primarily in Treasury
securities. This action helped increase the Fund's yield and positions the
portfolio nicely to take advantage of historically wide spreads.

We also added a small high-yield component to the Fund. While this action helped
increase the Fund's yield, it also had a negative effect on the Fund's principal
return. High-yield bonds suffered during our holding period due to credit
quality concerns and a lack of demand. We were able to minimize the effects of
this due to our small and broadly diversified position in these bonds.

The yield curve took on an inverted shape during the year, meaning that
shorter-term bonds offered higher yields than long-term bonds. Our yield curve
positioning in the zero to three-year range as well as our long-term Treasury
holdings helped the Fund make the most of this situation.

HOW WAS THE FUND STRUCTURED IN TERMS OF SECTORS AND QUALITY?*
The Fund's average quality changed only slightly due to the addition of
high-yield securities. As of June 30, 2000, the Fund's average quality was "AA,"
and 64% of the portfolio was invested in "AAA"-rated securities. Securities
rated "AA" comprised 5% of the portfolio; those rated "A" comprised 16%;
securities rated "BBB" comprised 9%; and high-yield bonds comprised 6%.

U.S. Treasuries comprised 19% of the Fund at fiscal year end, while 29% was
invested in mortgage-backed securities, 35% in corporate bonds, 12% in asset
backed securities, 4% in agency securities and 1% in money market securities.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Over time, we believe the Federal Reserve will remain committed to controlling
inflation and will be successful in its efforts to slow down the economy. This
should contribute to a positive bond market environment. Supply and demand
changes in the market may cause spreads to remain volatile and wider than their
historical averages. Nonetheless, we believe that over the long-term
non-Treasury securities will continue to present attractive investment
opportunities.

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 prior to the acquisition by 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, 1995. 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 Class B
shares is based on Class A share performance adjusted to reflect the difference
in 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 fees. By contrast, the
performance of the Fund reflects the deduction of these services as well as the
deduction of sales charges on Class A shares and applicable contingent deferred
sales charges on Class B and Class C shares. Performance for Class C shares is
based on Class B share performance adjusted to reflect the difference in sales
charges.

The Lipper Intermediate Investment Grade Index consists of the equally weighted

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

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Government Bond Fund I share class
posted a total return of 4.33%. (For information on other share classes and
performance comparisons to indexes, please see pages 18-19.)

HOW WOULD YOU DESCRIBE THE YEAR'S MARKET CLIMATE?
The 12-month period was characterized by rising interest rates, as the U.S.
economy continued to surprise investors with high growth and low inflation.
Uncomfortable with this situation, the Federal Reserve embarked on a
rate-tightening campaign that eventually raised the federal funds rate by 1.75
percentage points. More important, short-term market rates increased by more
than 1 percentage point.

High levels of spread volatility characterized the performance of the
mortgage-backed sector during the year. (Spreads refer to the differences in
yields between non-Treasury bonds, such as agency, corporate and mortgage-backed
securities, and comparable-maturity Treasury bonds. When spreads widen, prices
on non-Treasury bonds decline, and vice versa.) At the beginning of the fiscal
year, increasing concerns over potential Federal Reserve tightening and Y2K
caused interest rate volatility to spike, and spreads on mortgage-backed
securities widened. But, after the Federal Reserve announced it would provide
enough liquidity to combat any Y2K problems, spreads tightened.

The recovery was short-lived. During the first quarter of 2000, strong global
growth, a soaring equity market and high levels of non-public debt led to
concerns that the Federal Reserve would become significantly more restrictive.
In addition, record U.S. government surpluses led the U.S. Treasury to implement
a buyback program of federal debt. These factors resulted in an inversion of the
yield curve, and spreads re-tested their historical highs. Furthermore, the high
levels of growth in some government agencies, particularly Freddie Mac and
Fannie Mae, have come under Congressional scrutiny. We do not expect any changes
in the legal or credit status of these agencies, but spreads on their debt have
risen significantly. Also, this event has led to a dislocation in the mortgage
market, where the value of Ginnie Mae securities has risen significantly in
relation to those of Fannie Mae and Freddie Mac.

HOW DID THESE EVENTS INFLUENCE THE FUND?
The Federal Reserve's tightening of monetary policy negatively contributed to
the Fund's performance by increasing the level of spread volatility and the
overall level of interest rates. These factors caused bond prices to fall, which
negatively affected Fund performance. In addition, our emphasis on agency-issued
mortgage-backed securities hurt price performance, as spreads widened to levels
not seen in years. We continued to emphasize high-quality mortgage securities
because they offered attractive yield benefits compared to Treasuries.

The Fund remained underweighted in long-term Treasury securities, which
outperformed most other sectors. The demand for liquidity, the federal
government's buyback program and the inverted yield curve all significantly
benefited longer-term Treasuries.

Overall, though, the Fund's performance was solid relative to the year's market
conditions. The Fund performed relatively well despite high volatility among
interest rates and spreads and an inverted yield curve.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
We focused on maintaining a high-quality and liquid portfolio and on keeping the
Fund's duration close to its target of 5.5 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.) The Fund's duration varied from
5.3 to 5.4 years during the year, due in part to the varying duration of
mortgage-backed securities and the increased interest rate volatility.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Given the uncertainty surrounding inflation, economic growth and Federal Reserve
policy, we expect rates and spreads to remain volatile throughout the summer
months. But, we believe the economy will start showing signs of a slowdown in
the fall, which should alleviate any further pressure on the Federal Reserve to
continue raising rates. By the end of the year, we expect interest rates to
remain steady or fall slightly. The yield curve should shift to a flat position,
and overall interest rate volatility should drop. As such, we expect spread
securities to perform well during the second half of 2000.

We plan to continue heavily overweighting spread securities in this market. In
addition, we expect to maintain duration at or slightly above our target
duration to keep interest rate risk at a neutral level.

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 Lehman
Brothers Government Bond Index, an unmanaged index comprised of securities
issued by the US Government. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management fees. By contrast, the performance of the
Fund reflects the deduction of these services as well as the deduction of sales
charges on Class A shares and applicable contingent deferred sales charges on
Class B and Class C shares.

The Salomon Brothers 3-7 Year Treasury Index is comprised of US Government
agency and Treasury securities and mortgage-backed securities.

The Lipper General US Government Fund Index consists of the equally weighted
average monthly returns of the largest funds within the universe of all funds in
the category.

The benchmark index for the One Group Government Bond Fund has changed from the
Salomon Brothers 3-7 Year Treasury Index to the Lehman Brothers Government Bond
Index to better represent the investment policies for comparison purposes.

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

HOW DID THE FUND PERFORM?
One Group Treasury & Agency Fund I share class posted a total return of 4.42%
for the year ended June 30, 2000. (For information on other share classes and
performance comparisons to indexes, please see page 22.)

The Fund's share price declined from $9.81 on June 30, 1999, to $9.64 on June
30, 2000--a decrease of 1.73%. This decline was within our expectations, as the
Fund's average maturity is 3.5 years, and the 3.5-year Treasury note with a
5.38% coupon and a maturity date of June 30, 2003, had a price decline of 1.50%
during the same period. As with all Treasury and agency securities, all of the
Fund's holdings will mature at least at par. But, prior to maturity, their
market values may fluctuate. The daily practice of marking-to-market the Fund's
holdings reflects these fluctuating market values.

The primary cause of the decline in Treasury prices and associated increase in
yields was the Federal Reserve's tightening policy. The resulting decreases in
market prices, while significant, are not outside the norm of what can be
experienced from time to time. In addition, a one-year decline often is just the
reversal of the prior year's gains. This was the case in 1999 and 1998. Because
of this, we recommend that investors focus on longer-term return prospects and
remain disciplined during short-term periods of decline.

HOW WOULD YOU DESCRIBE THE YEAR'S MARKET CLIMATE?
Interest rates increased across the board during the fiscal year, as the U.S.
economy remained strong. Concerned about the potential for an increase in
inflation, the Federal Reserve began a tightening campaign that increased the
federal funds rate by 1.75 percentage points. More important, short-term market
rates rose by more than 1 percentage point.

At the beginning of the fiscal year agency yields relative to Treasuries were at
historic highs due to Y2K concerns. Those concerns were alleviated somewhat in
October, when the Federal Reserve announced that it would provide enough
liquidity in the system to combat potential Y2K problems. This, combined with
the growing belief that Y2K would pass without much economic disruption, helped
agency spreads tighten. (Spreads refer to the differences in yields between
non-Treasury bonds, such as agency, corporate and mortgage-backed securities,
and comparable-maturity Treasury bonds. When spreads widen, prices on non-
Treasury bonds decline, and vice versa.)

But, early in the new year the U.S. Treasury announced that its growing
surpluses would allow it to start buying back longer-term Treasury securities.
As it became clear that fewer Treasury securities would be available to
investors, Treasury prices moved higher and yields moved lower relative to other
securities, such as agencies. The perceived decrease in the supply of Treasuries
also contributed to an inverted yield curve, whereby yields on short-term
securities were higher than yields on long-term securities.

HOW DID THE FUND'S YIELD CHANGE?
With interest rates on the rise during the fiscal year, yields increased and
bond prices declined. The Fund's 30-day SEC yield on I shares increased from
5.99% on June 30, 1999, to 6.49% on June 30, 2000.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our ongoing strategy involves analyzing the relative value of the various market
sectors through a rigorous research process. For the fiscal year ended June 30,
2000, our efforts focused on the selective use of agency securities, due to the
yield advantage agencies offered over Treasuries. Within the Treasury component
of the Fund, we emphasized securities that offer the best return potential over
a six- to 12-month time horizon. We also invested a small portion of the
portfolio in Treasury inflation-protected securities, as we believe they have
attractive return potential versus regular Treasury securities.

The yield advantage of the agency portion of the portfolio was a positive
contributor to Fund performance, but it was offset a bit by the lagging price
performance of these securities relative to Treasuries. Another positive
influence was the strong relative performance of the Treasury
inflation-protected securities we purchased.

The Fund's maturity remained slightly longer than average, which was a negative
influence on total return.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

In a rising interest rate environment, prices on longer-term securities
generally fall more than prices on shorter-term securities.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Fund's current position reflects opportunities that are available in the
government bond market. For example, agency yields versus Treasury yields are
very attractive from an historical perspective. Therefore, the Fund remains
fully allocated to the agency sector. Within the Treasury component, our focus
is on certain seasoned securities that offer a yield advantage and the potential
for higher total return over the next year. We also believe that the absolute
level of yields is relatively attractive, and the portfolio's average maturity
remains slightly longer than average.

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 Treasury &
Agency Fund on January 20, 1997, adjusted to reflect the expenses and sales
charges associated with the Fund. 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 fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Short US Government Fund Index consists of the equally weighted
average monthly returns of the largest funds within the universe of all funds in
the category.

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

HOW DID THE FUND PERFORM?
One Group High Yield Bond Fund I share class posted a total return of -0.75% for
the year ended June 30, 2000. (For information about other share classes and
performance comparisons to indexes, please see pages 25-26.)

A steadily rising interest rate environment along with the continued economic
expansion and the U.S. Treasury Department's announcement that it would buy back
Treasury securities caused prices to fall, yields to rise and spreads to
increase for high-yield bonds and all other non-Treasury sectors. (Spreads refer
to the differences in yields between non-Treasury bonds--in this case high-yield
bonds--and comparable maturity Treasury bonds. When spreads widen, prices on
non-Treasury bonds decline, and vice versa.) The high-yield sector also was
negatively affected by an overall decrease in demand throughout most of the
period.

DID THE FUND'S YIELD BENEFIT FROM THIS ENVIRONMENT?
The Fund's 30-day SEC yield on I shares increased nearly 2 percentage points
during the year--from 9.33% on July 1, 1999, to 11.25% on June 30, 2000. High-
yield bonds are influenced by interest rate changes, but their higher average
coupon may insulate them from rising rates more than other fixed income
securities. As such, the Fund's higher yield was the result of a combination of
factors: higher overall interest rates; a widening of spreads; and the Fund
becoming more fully invested in high-yield bonds and less so in commercial paper
and other short-term products.

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary, ongoing strategy is to limit risk and volatility by maintaining a
broadly diversified portfolio offering exposure to a variety of issuers and
industries. At fiscal year-end, the Fund had investments in more than 190
companies in 31 different industries. At the core of this strategy is research.
We employ fundamental investment analysis to thoroughly examine the underlying
credit quality of each company we consider for purchase. In addition, we
continuously review and monitor each security in the portfolio to uncover any
credit developments.

Our credit selection process and underweighting in what we believe are the
riskiest segments of the high-yield market position the Fund more conservatively
than a number of its peers. As such, we were not as aggressively positioned in
the volatile telecommunications sector. This negatively influenced Fund
performance in the first two months of 2000, when the more speculative credits
in the telecommunications sector offered strong performance. But, this trend
began reversing in March, and by the end of May the Fund's more conservative
stance was back in favor.

We maintained the Fund's duration in a fairly tight band during the year.
(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.) Duration ranged from 4.61 years to 4.96 years and ended the fiscal year
at 4.61 years.

HOW DID YOU MANAGE THE FUND'S CREDIT QUALITY?*
One of the key elements of successfully managing a high-yield bond portfolio is
avoiding deteriorating credits or selling them before they decline
significantly. We attempt to do this by closely monitoring every bond in the
portfolio. We try to stay ahead of the market on developing news and spot clues
to potential deteriorations of individual credits or industry sectors.

As new cash moved into the Fund, our goal was to improve the Fund's overall
credit quality. By year-end, 20% of the Fund was invested in credits rated "BB,"
compared to 12% on June 30, 1999. At fiscal year-end, the majority of the Fund's
assets--68%--were invested in securities rated "B." Cash and securities rated
"BBB" comprised 4% of the Fund; "CCC" comprised 3%; and non-rated and other
securities comprised 6%. The Fund's average credit quality was "B" as of June
30, 2000.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Our strategy of investing in a diversified portfolio of better-quality
high-yield bonds should perform well over the next year, given that the
attractive yields available in this sector should fuel demand. We believe that
if we are successful in managing credit risk, the Fund's performance should
remain solid relative to the high-yield market as a whole. Rather than focusing
on the anticipated direction of interest rates, we will constantly monitor the
Fund's credit quality to determine how the Fund's investments will perform in
various economic cycles.

Although the Fund's yield may be higher than that of fixed income funds that
purchase higher-rate securities, the potentially higher yield is a function of
the greater risk that the Fund's share price will decline.

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 (CSFB) Global 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 fees. By contrast, the performance of the Fund reflects
the deduction of these services as well as the deduction of sales charges on
Class A shares and applicable contingent deferred sales charges on Class B and
Class C shares.

The CSFB Global High Yield Index was formerly named the CSFB High Yield Index.

The CSFB Domestic Plus High Yield Index is an unmanaged index comprised of high
yield securities, within developed nations, that are selected primarily on the
basis of size, liquidity and diversification to be representative of the high
yield bond market.

The Lipper High Yield Bond Fund Index is an unmanaged index typically comprised
of the 30 largest mutual funds aimed at high current yields from fixed income
securities. These funds have no quality or maturity restrictions and tend to
invest in lower grade debt issues.

The CSFB Domestic Plus High Yield Index consists of the average monthly returns
of the CSFB Global High Yield Index for periods prior to January 1999.
Thereafter, the data is from the CSFB Domestic Plus High Yield Index, which
corresponds with the initiation of the CSFB Domestic Plus High Yield Index on
January 1, 1999.

Although the fund's yield may be higher than that of fixed income funds that
purchase higher-rated securities, the potentially higher yield is a function of
the greater risk that the fund's share price will decline.

(a) Represents cost for financial reporting purposes and differs from cost basis
    for federal income tax purposes by the amount of losses recognized for
    financial reporting purposes in excess of federal income tax reporting of
    approximately $4. Cost for federal income tax purposes differs from value by
    net unrealized appreciation (depreciation) of securities as follows (amounts
    in thousands):

(b) Amount is less than 1,000.

(c) Security exempt from registration under Rule 144A or Section 4(2) 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 $15,908 or 6.70% of net assets.

(d) Safety Kleen, which filed for protection under Chapter 11 of the Federal
    Bankruptcy Code, has accrued interest of $15 and amortized cost of $549.

(e) American Eco Corp., which filed for protection under Chapter 11 of the
    Federal Bankruptcy Code, has accrued interest of $13 and amortized cost of
    $277.

 * Variable rate securities having liquidity sources through bank letters of
   credit or other cards and/or liquidity agreements. The interest rate, which
   will change periodically, is based upon prime rates or an index of market
   rates. The rate reflected on the Schedule of Portfolio Investments is the
   rate in effect at June 30, 2000.

Abbreviations

<TABLE>
<S>          <C>
ARM          Adjustable Rate Mortgage
CD           Certificate of Deposit
CMO          Collateralized Mortgage Obligation
CMT          Collateralized Mortgage Trust
COFI         Cost of Funds Index
HB           High Coupon Bonds (a.k.a. "IOettes") represent the right to
             receive interest payment 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.
IF           Inverse Floaters represent securities that pay interest at a
             rate that increases (decreases) with a decline (increase) in
             a specified index.
IO           Interest Only 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.
PIK          Paid In Kind
PO           Principal Only 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.

   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 mean of the latest bid and ask prices. Options
     traded over-the-counter are valued using dealer-supplied valuations.
     Investments for which there are no such quotations or valuations are
     carried at fair value as determined by the Pricing Committee which is
     comprised of members from One Group Administrative Services, ("OGA"), an
     affiliate of Banc One Investment Advisors Corporation (the "Advisor"), and
     The One Group Services Company (the "Administrator") under the direction of
     the Board of Trustees.

     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.

     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, letters of credit or any combination of cash,
     such securities or letters of credit

     as collateral equal at all times to at least 100% of the market value plus
     accrued interest on the securities lent. The Funds receive payments from
     borrowers equivalent to the dividends and interest that would have been
     earned on securities lent while simultaneously seeking to earn interest on
     the investment of cash collateral.

     Collateral is marked to market daily to provide a level of collateral at
     least equal to the market value of securities lent. There may be risks of
     delay in recovery of the securities or even loss of rights in the
     collateral should the borrower of the securities fail financially. However,
     loans will be made only to borrowers deemed by the Advisor to be of good
     standing and creditworthy under guidelines established by the Board of
     Trustees and when, in the judgment of the Advisor, the consideration which
     can be earned currently from such securities loans justifies the attendant
     risks. Loans are subject to termination by the Funds or the borrower at any
     time, and are, therefore, not considered to be illiquid investments. As of
     June 30, 2000, the following Funds had securities with the following market
     values on loan (amounts in thousands):

</TABLE>

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

     SECURITY TRANSACTIONS AND RELATED INCOME

     Security transactions are accounted for on a trade date basis. Net realized
     gains or losses from sales of securities are determined on the specific
     identification cost method. Interest income and expenses are recognized on
     the accrual basis. Dividends are recorded on the ex-dividend date. Net
     investment income includes premium amortization and discount accretion for
     both financial reporting and tax purposes. Amortization and accretion are
     calculated using the effective interest method.

     EXPENSES

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

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income are declared 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. Prior to June 30, 1998, costs were being
     amortized using the straight-line method over a period of five years
     beginning with the commencement of each Fund's operations. After June 30,
     1998, costs are expensed as incurred. All such costs, which are
     attributable to more than one Fund of the Trust, have been allocated among
     the respective Fund's pro-rata, based on the relative net assets of each
     Fund. In the event that any of the initial shares are redeemed during such
     period by any holder thereof, the related Fund will be reimbursed by such
     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.

     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 contracts primarily as a means to hedge against adverse
     fluctuations in securities held or planned to be purchased by the funds.

     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 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.

     The following is a summary of futures outstanding as of June 30, 2000:

     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.

3. SHARES OF BENEFICIAL INTEREST:

   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares, and any series may be classified
   or reclassified into one or more classes. The Trust is registered to offer
   fifty-four series and six classes of shares: Class I, Class A, Class B, Class
   C, Class S and Service 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 only. Class A shares are subject to initial sales
   charges, imposed at the time of purchase, in accordance with the Funds'
   prospectus. Certain redemptions of Class B and Class C shares are subject to
   contingent deferred sales charges in accordance with the Funds' prospectus.
   As of June 30, 2000, there were no shareholders in Class C of the Ultra
   Short-Term Bond Fund, the Short-Term Bond Fund, and the Treasury and Agency
   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. See Schedules of Capital Stock Activity.

4. INVESTMENT ADVISORY, ADMINISTRATION, AND DISTRIBUTION AGREEMENTS:

   The Trust and the Advisor are parties to an investment advisory agreement
   under which the Advisor is entitled to receive an annual fee, computed daily
   and paid monthly, equal to the following percentages of the Funds' average
   daily net assets: 0.55% of the Ultra Short-Term Bond Fund, 0.60% of the
   Short-Term Bond Fund, the Intermediate Bond Fund, the Bond Fund and the
   Income 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.

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

   Banc One High Yield Partners, LLC, the sub-advisor of the One Group High
   Yield Bond Fund, was formed as a limited liability company under an agreement
   between Banc One Investment Advisors and Pacholder Associates, Inc. Under the
   Agreement, Pacholder is responsible for providing portfolio management
   services on behalf of Banc One High Yield Partners, LLC for the One Group
   High Yield Bond Fund. For its services, Banc One High Yield Partners, LLC is
   paid a fee by the Advisor.

   A Special Meeting of Shareholders ("Special Meeting") of the One Group Income
   Bond Fund (the "Fund") was held on November 19, 1999. At the meeting, a
   majority of the shareholders of record at the close of business on September
   23, 1999 approved a Sub-Investment Advisory Agreement between Banc One
   Investment Advisors Corporation and Banc One High Yield Partners, LLC with
   respect to the Fund. As a result, Banc One High Yield Partners, LLC now acts
   as sub-advisor to the Fund with respect to that portion of the Fund's assets
   designated by Banc One Investment Advisors for investment in corporate
   fixed-income securities and instruments which are rated below investment
   grade or unrated corporate fixed-income securities and instruments of similar
   quality. The Fund cannot invest more than 30% of its total assets in this
   type of security. Approval of the Sub-Investment Advisory Agreement did not
   result in any change in the Fund's investment restrictions or an increase in
   the contractual rate of any advisory fees payable by the Fund. For its
   services, Banc One High Yield Partners, LLC is paid a fee by the Advisor.

   The Trust and The One Group Services Company (the "Distributor") are parties
   to a distribution agreement under which shares of the Funds are sold on a
   continuous basis. Class A, Class B, and Class C shares are subject to
   distribution and shareholder services plans (the "Plans") pursuant to Rule
   12b-1 under the 1940 Act. As provided in the Plans, the Trust will pay the
   Distributor a fee of 0.35% of the average daily net assets of Class A shares
   of each of the Funds and 1.00% of the average daily net assets of the Class B
   and Class C shares of each of the Funds. Currently, the Distributor has
   voluntarily agreed to limit payments under the Plans to 0.25% of average
   daily net assets of the Class A shares of each Fund, 0.75% of average daily
   net assets of the Class B shares of the Ultra Short-Term Bond Fund, the
   Short-Term Bond Fund and the Treasury & Agency Fund, 0.90% of average daily
   net assets of the Class B shares of the Intermediate Bond Fund, the Bond
   Fund, the Income Bond Fund, the Government Bond Fund and the High Yield Bond
   Fund and 0.90% of the average daily net assets of the Class C shares of the
   Intermediate Bond Fund, the Bond Fund, the Income Bond Fund, the Government
   Bond Fund and the High Yield Bond Fund. Up to 0.25% of the fees payable under
   the Plans may be used as compensation for shareholder services by the
   Distributor and/or financial institutions and intermediaries. Fees paid under
   the Plans may be applied by the Distributor toward (i) compensation for its
   services in connection with distribution assistance or provision of
   shareholder services; or (ii) payments to financial institutions and
   intermediaries such as banks (including affiliates of the Advisor), brokers,
   dealers and other institutions, including the Distributor's affiliates and
   subsidiaries as compensation for services or reimbursement of expenses
   incurred in connection with distribution assistance or provision of
   shareholder services. Class I shares of each Fund are offered without
   distribution fees. For the year ended June 30, 2000, the Distributor received
   $760,556 from commissions earned on sales of Class A shares and redemptions
   of Class B and Class C shares, of which the Distributor re-allowed $439,833
   to affiliated broker-dealers of the Funds.

   Certain officers of the Trust are affiliated with the Administrator. Such
   officers receive no compensation from the Funds for serving in their
   respective roles.

   The Advisor, the Administrator and the Distributor voluntarily agreed to
   waive a portion of their fees. For the year ended June 30, 2000, fees in the
   following amounts were waived (amounts in thousands):

6. LINE OF CREDIT:

   The Trust and State Street Bank and Trust Company ("State Street") and a
   group of banks (collectively, the "Banks") entered into a financing agreement
   dated October 19, 1999. Under this agreement, the Banks provide an unsecured
   committed credit facility in the aggregate amount of $500 million. The credit
   facility is allocated, under the terms of the financing agreement, among the
   Banks. Advances under the agreement are taken primarily for temporary or
   emergency purposes, including the meeting of redemption requests that
   otherwise might require the untimely disposition of securities, and are
   subject to each Fund's borrowing restrictions. Interest on borrowings is
   payable at the Federal Funds Rate plus 0.50% on an annualized basis. Interest
   on borrowings during the period from and including December 15, 1999 to
   January 17, 2000, was payable at 0.50% plus the higher of the Fed Funds
   Effective Rate plus 0.50% or the Fed Funds Target Rate plus 1.50%. A
   commitment fee of 0.10% per annum will be incurred on the unused portion of
   the committed facility, which is allocated to all funds.

   For the year ended June 30, 2000, there were no borrowings by the Funds under
   the agreement.

7. DEFERRED TRUSTEES FEES:

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

8. CONVERSION OF COMMON TRUST FUNDS:

   The net assets of certain common trust funds managed by First Chicago NBD
   Investment Management Company (an affiliate of the Advisor) were exchanged in
   a tax-free conversion for Class I shares of the corresponding Funds. The
   transactions were accounted for by a method followed for tax purposes in a
   tax-free business

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

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

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of portfolio investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Ultra Short-Term Bond Fund, the
Short-Term Bond Fund, the Intermediate Bond Fund, the 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, 2000, the results of each of their operations for the year
then ended and the changes in each of their net assets and the financial
highlights for each of the periods presented (other than those statements of
changes in net assets and financial highlights that have been audited by other
independent accountants), in conformity with accounting principles generally
accepted in the United States. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits, which included confirmation of securities at June 30,
2000 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above. The financial statements of the
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.
