ONE GROUP INVESTMENT TRUST MID CAP GROWTH PORTFOLIO
- --------------------------------------------------------------------------------

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. The Mid Cap Growth Portfolio, which seeks to provide capital appreciation and
secondarily, current income from a portfolio of mid-cap stocks, rose 12.62% in
the 12 months ended December 31, 2004. This compares with a gain of 14.00% for
the S&P MidCap 400/BARRA Growth Index.

Q. WHY DID THE PORTFOLIO PERFORM IN THIS WAY?
A. The U.S. equity markets recorded another year of gains as strong earnings
growth and healthy corporate balance sheets increased investor confidence
despite rising short-term interest rates, high oil prices and the twin deficits.
The Portfolio performed well during 2004, outdistancing its peer group the
Lipper Midcap Growth Index. However, it underperformed its benchmark, the S&P
MidCap 400/BARRA Growth Index. The Portfolio's stock selection in the
information technology and consumer discretionary sectors was particularly
strong. However, the Portfolio's financial and industrial names underperformed
their benchmark peer group and hindered relative performance.

At the stock level, Sepracor and Coach positively contributed to the Portfolio's
performance. Shares of Sepracor advanced upon Food and Drug Administration
approval of Lunesta, a new prescription sleep aid. Lunesta has been approved for
use beyond the 7-10-day period to which most sleep aids are restricted, giving
it a unique selling point versus the current market leader, Ambien. The drug,
known as Estorra during development, was scheduled to be available in pharmacies
in mid-January and is priced roughly 10% higher than Ambien. Coach, which
produces handbags and accessories, reported a 60% increase in third-quarter
earnings as sales grew 33%. Profits were driven by its transitional and fall
products, with limited edition merchandise selling extremely well and at higher
price points.

Although the Portfolio experienced positive results, a few names within the
portfolio hindered performance, particularly New York Community Bancorp and
Synopsys. Shares of New York Community Bancorp declined after the positioning of
its balance sheet proved vulnerable to shifting yield curves. Rumors had
abounded that Citigroup was in talks to acquire the company, however, when an
acquirer failed to emerge, the company's share price declined. Synopsys, a
business-software maker, saw its share price decline after delivering a negative
outlook for its fiscal year. Both positions were sold during the year.

Q. HOW WAS THE PORTFOLIO MANAGED?
A. During the period under review, management of the Portfolio was transitioned
to Christopher Jones and Timothy Parton. The portfolio manager change did not
affect the Portfolio's investment objectives or guidelines. The Portfolio will
continue to be managed using a "bottom-up" approach to its construction.
Portfolio Managers will base their stock selection on proprietary company
research complemented by research derived from third-party sources. The research
process is designed to identify companies with predictable and durable business
models deemed capable of achieving sustainable growth. Potential investments are
subjected to rigorous financial analysis and a disciplined approach to
valuation.

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

The performance of the Mid Cap Growth Portfolio is measured against the S&P
Midcap 400/BARRA Growth Index, an unmanaged index representing the performance
of the lowest price-to-book securities in the S&P Midcap 400 Index. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Portfolio reflects the
deduction of these expenses.

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

ONE GROUP INVESTMENT TRUST MID CAP VALUE PORTFOLIO
- --------------------------------------------------------------------------------

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. The Mid Cap Value Portfolio, which seeks to provide capital appreciation from
a portfolio of mid-cap value stocks, returned 15.40% in the 12 months ended
December 31, 2004. Although the Portfolio posted strong gains, it underperformed
its benchmark, the S&P MidCap 400/BARRA Value Index, which returned 18.93% over
the same period.

Q. WHY DID THE PORTFOLIO PERFORM IN THIS WAY?
A. The majority of the relative underperformance came in the fourth quarter as
the market experienced a strong reversal from high-quality to low-quality
stocks. This development hindered the Portfolio's performance as our overriding
focus is on quality and value. When these stocks are not in favor, we tend to
underperform.

In terms of what specifically helped the Portfolio's performance, our
overweighting and stock selection in the energy sector as well as our stock
selection in consumer staples were strong contributors. The energy sector
benefited from the rally in oil and natural gas prices during the early fall. On
the flip side, our stock selection in financials and information technology were
the main performance detractors.

A primary contributor in energy was Valero Energy, the leading U.S. independent
oil refiner. Valero experienced a solid year of earnings and was also added to
the S&P 500 Index. Another strong name in 2004 was Pentair, which implemented
two strategic moves. Early in the year, the company acquired WICOR Industries,
which transformed Pentair into a global leader in water technologies, including
well pumps, sump pumps, and pool and spa equipment. Continuing to streamline the
operations, the company sold off its tool division to Black & Decker. In
addition to these strategic realignments, Pentair reported strong earnings and
increased its quarterly dividend for the 28th consecutive year.

Although a significant number of the Portfolio's holdings experienced
double-digit returns, there were some weak performers. Among the names that
disappointed was Omnicare, the nation's largest provider of pharmaceutical and
related services to long-term care facilities. The company reported
disappointing earnings as pricing pressures increased and medical reimbursements
decreased. Sovereign Bancorp, one of the largest thrifts in the U.S., was
another detractor. The stock lost some ground early in the year following a
realization that it was unlikely to be acquired in the near future. However, the
company continued its own acquisition strategy, acquiring both Seacoast
Financial Services and Waypoint Financial. In addition, Sovereign Bancorp
declared a cash dividend increase of 20% on its common stock.

Q. HOW WAS THE PORTFOLIO MANAGED?
A. During the period under review, management of the Portfolio was transitioned
to Jonathan Simon and Lawrence Playford. The portfolio manager change did not
affect the Portfolio's investment objectives or guidelines. The Portfolio will
continue to be managed using a "bottom-up" approach to its construction.

With regards to performance, despite the Portfolio's solid gains for the period,
performance relative to the market was somewhat muted by lack of exposure to the
highly cyclical and highly leveraged segments of the market that were the
driving force behind the U.S. equities rally during the fourth quarter. As is
often the case, our overriding focus on quality and value - which generally
avoids investments in highly cyclical and leveraged companies - works to smooth
out portfolio performance over time.

the lowest price-to-book securities in the S&P Midcap 400 Index. Investors are
unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Portfolio reflects the
deduction of these expenses.

ONE GROUP INVESTMENT TRUST DIVERSIFIED MID CAP PORTFOLIO
- --------------------------------------------------------------------------------

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. The Diversified Mid Cap Portfolio, which seeks to provide long-term capital
growth from a diversified portfolio of equity securities with intermediate
capitalizations, returned 14.42% in the twelve months ended December 31, 2004.
This compares with a gain of 16.48% for the S&P MidCap 400 Index, the
Portfolio's benchmark.

Q. WHY DID THE PORTFOLIO PERFORM IN THIS WAY?
A. The Portfolio was in a transition phase for the latter part of the year, as a
new team took over its management in early September. The team executed a
transition of the Portfolio slowly over time to minimize excessive transaction
costs and shield clients from the unnecessary risk of high volatility and
turnover. Due to a gradually executed transition plan, performance during the
fourth quarter was only slightly behind its benchmark.

It was during this transition period that the analytical factors employed by the
Portfolio management team began to have an impact. In the fourth quarter, as the
Portfolio progressed with its transition, analytical factors were able to
positively contribute toward performance. At the sector level, health care was
the top contributor, as the investment process correctly suggested
underweighting the pharmaceuticals and biotech industry group. In addition,
stock selection in the health care services group positively impacted the
sector's showing. Telecommunication services also made a significant
contribution to performance, as the model's factors worked very well in that
sector.

Q. HOW WAS THE PORTFOLIO MANAGED?
A. During the period under review, management of the Portfolio was transitioned
to Silvio Tarca. The portfolio manager change did not affect the Portfolio's
investment objective or guidelines. The Diversified Mid Cap Portfolio seeks to
capitalize upon enduring market anomalies. The portfolio managers use a
disciplined portfolio construction process that focuses on exposure to valuation
and momentum factors, which the managers believe best capture investor-driven
market anomalies. The Portfolio looks to hold good "value" stocks with
reasonable momentum and very strong momentum, stocks relative to the Portfolio's
index, the S&P MidCap 400 Index.

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. For the year, the Portfolio outperformed its benchmark, the Russell 1000
Growth Index by 0.75% (7.05% vs. 6.30%).

Q. WHY DID THE PORTFOLIO PERFORM THIS WAY?
A. Positive stock selection within the industrial cyclical, capital markets and
basic material sectors led performance for the 2004 period. Adding value in the
basic materials sector were Portfolio holdings in U.S. Steel and Praxair, as
each company benefited from a strong resurgence in global demand for both steel
and industrial gas products. Additionally, holdings in Chicago Mercantile and
Google positively contributed to performance as these two IPO's, which were
purchased in 2004, started out strong and continued to rise as investors placed
premiums on their business models and franchises. In capital markets, Charles
Schwab was another positive contributor to the Portfolio's performance, as its
stock rose on a returning CEO, one who continues to execute a restructuring plan
highlighted by increased focus on cost cutting and greater competitive pricing.

The Portfolio's weakest stock selection for the period was in the consumer
cyclical, health services and semiconductors sectors. In health services, the
stock of Omnicare, a pharmacy services company to long-term care facilities,
plummeted mid year in reaction to an announced change in the Medicare
reimbursement procedures, which may negatively impact company earnings. Our
underweight position in Yahoo also hurt the Portfolio's performance, as the
company had a tremendous year, rising more than 65% as it continued to grow its
revenue and profits significantly.

Q. HOW WAS THE PORTFOLIO MANAGED?
A. During the period under review, management of the Portfolio was transitioned
to Marc Baylin and Giri Devulapally. The portfolio manager change did not affect
the Portfolio's investment objective or guidelines. At a high level, we
continued to manage the Portfolio with a largely sector-neutral,
style-consistent approach. Driving our investment results was the stock
selection expertise of our growth Portfolio management team, who based their
findings on the proven insights of our team of global equity analysts. At the
stock-specific level, the Portfolio is mostly concentrated in consistent growth
companies, defined as those companies with strong business franchises and
reasonable valuations, along with those cyclical growers with favorable
supply/demand characteristics, strong secular growers and opportunistic deep
value companies. In selecting these companies, we use a systematic valuation
methodology to capture both their inherent value and the momentum dynamic
surrounding growth companies.

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. Year-to-date through December 31, 2004, the Portfolio returned 7.05%, while
its benchmark, the S&P Super Composite 1500 Index, returned 11.79%.

Q. WHY DID THE PORTFOLIO PERFORM THIS WAY?
A. Contributing the most to performance in 2004 was positive stock selection
within the finance, network technology and semiconductors sectors. On the stock
specific level, our overweight positions in Qualcomm, Motorola and Freddie Mac
contributed positively to results. Qualcomm was helped by better cell phone
replacement rates, better-than-expected selling prices for cell phones and
improving traction in Wideband Code-Division Multiple Access, a type of digital
cellular technology. In the network technology sector, Motorola benefited from
increasing market share, care of Nokia, which lost market share owing to
execution issues earlier in the year. The company also benefited from a raft of
new products, which sold well upon introduction, and strong sales of existing
products. Overall, stock selection within the semiconductor sector was very
strong through the year, making it one of the strongest contributing sectors for
the year.

Detracting from returns was stock selection within the retail, media and
consumer cyclical sectors. In the consumer cyclical sector, our underweight
position in Johnson & Johnson negatively impacted the Portfolio, as the shares
of this medical products provider rose on news of its acquisition of medical
devices company, Guidant. Investors saw Guidant as a nice strategic addition to
J&J's product offerings, owing to its strong cardiac care franchise. In media,
the Portfolio's holding in Viacom served to diminish performance, despite
significant share repurchases by the company. Regardless of this
underperformance, we still like Viacom, especially the new management at its
Paramount film division, along with its renewed focus on its cable and radio
properties, both of which support our conviction that our patience will be well
rewarded over time. Also in media, our underweight position in Yahoo hurt the
Portfolio's performance, as the company had a tremendous year, rising more than
65% as it continued to grow its revenue and profits significantly. In retail,
our overweight position in Jones New York detracted from the Portfolio's
performance; although the stock had a modest positive return for the year, it
underperformed a strong sector. In particular, the market reacted negatively to
its acquisition of luxury retailer Barney's.

Q. HOW WAS THE PORTFOLIO MANAGED?
A. During the period under review, management of the Portfolio was transitioned
to Susan Bao and Helge Skibeli. The portfolio manager change did not affect the
Portfolio's investment objective or guidelines. We continued to manage the
Portfolio with a largely sector-neutral, style-consistent approach, which
stresses effective stock selection. The focus of the Portfolio continues to be
on identifying and concentrating in undervalued companies with leadership
positions within their respective industries, specifically those with solid
business models, high returns on capital and strong free cash.

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. For the year ended December 31, 2004, the Equity Index Portfolio posted a
total return of 10.34%, compared to a total return of 10.87% for the S&P 500
Index(1), the unmanaged group of stocks the Portfolio seeks to track. By
strictly following our benchmark positions and weightings, and remaining fully
invested throughout the year, we were able to closely track the index's
performance before fees.

Q. WHAT LED TO THE GOOD RETURNS AMONG STOCKS?
A. A quick and decisive resolution to the November 2004 presidential election
reassured investors who had worried about a repeat of the 2000 election debacle.
Investors displayed a confidence that pushed stock prices ahead. In addition,
good corporate earnings growth continued to provide a positive backdrop for
stock market growth.

Q. WHICH SECTORS OFFERED NOTABLE PERFORMANCE?
A. The energy minerals and health services sectors were the best-performing
market segments for the year, each posting returns of approximately 30%. Only
two sectors generated negative results -- electronic technology was down 0.79%,
and health technology was off 1.86% for the year.

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. For the year ended December 31, 2004, the One Group Balanced Portfolio
returned 5.73%.

Q. WHY DID THE PORTFOLIO PERFORM THIS WAY?
A. Over the course of the year, short-term yields increased as the Federal
Reserve raised the federal funds rate several times. Intermediate yields
decreased and longer maturity yields declined. The change in the relationship
between shorter and longer yields was beneficial to the Portfolio's fixed income
holdings, given our focus on longer maturity bonds. The Portfolio's holdings of
mortgage-backed securities were also beneficial as they outperformed most other
sectors in the Portfolio's benchmark. Duration had a very slight negative impact
on performance, as the Portfolio's fixed income holdings were longer than its
benchmark during periods of rising rates. An overweight of longer maturity bonds
had a beneficial impact as they performed much better than short or intermediate
bonds. Although the 10-year Treasury yield finished 2004 at nearly the same
level as it began the year, we believe that, with inflation creeping higher and
the prospect of at least another 100 basis points of Fed tightening, longer-term
Treasury yields will likely rise in 2005.

After strong equity performance in the past few months, we have become more
cautious about equity returns in 2005. Although equity valuations look more
attractive relative to bonds, when considering that interest rates appear to be
rising and corporate profits are at very high levels, the market multiples do
not look especially compelling at this time. Our forecast for 2005 is for
positive high-single digit gains in equities likely carried by earnings growth
(as opposed to multiple expansion), albeit at more moderate levels than we saw
in 2004.

Q. HOW WAS THE PORTFOLIO MANAGED?
A. During the period of review, there were changes in the portfolio management
team for the Portfolio. Anne Lester and a team of portfolio managers and
analysts manage the portfolio construction, investment strategy selection and
asset allocation for the overall Portfolio, while Scott Grimshaw continued to
serve as portfolio manager primarily responsible for the fixed-income portion of
the Portfolio.

Our fixed income Portfolio strategy is fairly neutral on risk. As such, we
expect to trade duration and curve positions tactically. We believe that
supportive technicals in the mortgage market should persist and that valuations
will be extremely tight; therefore, we expect to trade actively around a neutral
position. In investment grade credit, we favor a neutral position, with a bias
towards higher yielding names, as spreads remain at extremely tight levels. We
believe structured credit (ABS, CMBS) should perform well, despite the risk of a
widening in swap spreads.

Despite worries over fading profit growth, rising interest rates, a falling
dollar and high energy prices, 2004 ended with strong performance from the major
U.S. equity indices. Aiding a sharp, year-end rally were the swift and decisive
outcome of the U.S. presidential election and a decline in the price of oil.
Continued strong corporate profit growth and low longer-term interest rates also
helped the equity markets. In the U.S., the pattern of growth is expected to
shift from the household to the corporate sector, with a revival in investment
spending. This is likely to be accompanied by higher U.S. interest rates and
yields, with scope for an eventual resumption of dollar weakness.

In line with our equity strategy, we look to add value through a research driven
selection process that emphasizes stocks that we believe to be undervalued
relative to their long-term potential, regardless of their sector.

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 table above compares the average annual
return of the Portfolio, which holds a mix of stocks, bonds and other debt
securities to an unmanaged, broad-based index (i.e., the S&P 500 Index) as well
as supplemental indices for the periods indicated.

The performance of the Balanced Portfolio is measured against the S&P 500 Index,
an unmanaged index generally representative of the performance of large
companies in the U.S. stock market. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management fees. By contrast, the performance of the
Portfolio reflects the deduction of these expenses.

The Lipper Balanced Funds Index is a blended index consisting of both stock and
bonds with a typical stock-to-bond ratio of around 60% to 40%. The Lehman
Intermediate Government/Credit Index is an unmanaged index composed of debt
securities with maturities from one to ten years issued or guaranteed by the
U.S. Treasury, U.S. Government agencies, and quasi-federal corporations.

ONE GROUP INVESTMENT TRUST BOND PORTFOLIO
- --------------------------------------------------------------------------------

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. For the one-year period ended December 31, 2004, the Bond Portfolio posted a
total return of 4.13%. This compared similarly to the total return of the
portfolio's benchmark, the Lehman Brothers Aggregate Bond Index, which returned
4.34% for the year.

Q. HOW WOULD YOU CHARACTERIZE THE BOND MARKET'S PERFORMANCE IN 2004?
A. Three key investment themes prevailed throughout the year: a flattening of
the yield curve, as shorter-term rates increased and longer-term rates remained
relatively stable; spread compression, as the differences in yield (spreads)
between Treasury and non-Treasury sectors tightened; and the outperformance of
lower-quality credit sectors.

All of the non-Treasury sectors outperformed comparable-duration Treasuries
throughout the year. Corporate bonds were the best performers, followed by
mortgage and asset-backed securities. Within the corporate sector, lower-rated
securities fared the best in 2004, as investors sought yield. In the
investment-grade universe, bonds in the BBB-rated segment were the top
performers for the year.

Q. TO WHAT DO YOU ATTRIBUTE THE PORTFOLIO'S PERFORMANCE?
A. We continued to overweight mortgages and asset-backed securities during the
year, which affected performance in 2004. Security selection, particularly
within the mortgage sector, was a driver of the Portfolio's performance. We also
continued to underweight corporate bonds, and within the corporate sector we
maintained a high-quality bias. This strategy was a drag on overall performance.
In particular, our underweight in BBB-rated bonds detracted from results.

Q. DID YOUR DURATION STRATEGY INFLUENCE PERFORMANCE?
A. Consistent with our philosophy of de-emphasizing duration (sensitivity to
interest rate changes), we kept the Portfolio's duration within 10% of the
benchmark's. At year end, the Portfolio's duration was 4.2 years, compared to
4.3 years for the benchmark. As such, duration was neutral in terms of relative
performance.

PORTFOLIO PERFORMANCE REVIEW

Q. HOW DID THE PORTFOLIO PERFORM?
A. For the year ended December 31, 2004, the Government Bond Portfolio posted a
total return of 4.64%. This compares favorably with the 3.48% total return for
the Portfolio's benchmark, the Lehman Brothers Government Bond Index.

Q. HOW WOULD YOU CHARACTERIZE THE BOND MARKET OF 2004?
A. As short-term interest rates slowly moved upward throughout the year,
longer-term rates moved in a see-saw pattern from quarter to quarter. Although
the year began with the economy growing at a healthy pace, driven primarily by
consumer consumption and productivity growth, there were concerns that a
slowdown was imminent. This caused interest rates to decline in the first
quarter. But that sentiment was short lived, as employment and inflation figures
showed unexpected increases during the second quarter. This led to significant
upward movements in interest rates and a long-awaited change in Federal Reserve
monetary policy.

In the third quarter, the economy remained on its growth track, and the Federal
Reserve continued to raise the federal funds rate in a "measured" fashion. But,
as oil prices began a rapid surge upward, inflation fears mounted, which led to
renewed concerns of an economic slowdown and a decline in interest rates.

As we moved into the fourth quarter, an increase in business spending meant the
still-growing U.S. economy was no longer supported solely by consumer
consumption. Employment and inflation continued their modest moves upward. The
Federal Reserve implemented two 25-basis-point rate hikes, and longer-term rate
volatility subsided.

Q. HOW DID THE PORTFOLIO PERFORM IN THIS CLIMATE?
A. The Portfolio outperformed during the year, primarily due to its greater
exposure to mortgage-backed securities. In particular, exposure to
collateralized mortgage obligations, or CMOs, led to good relative performance
for the year.

Q. WHAT WERE YOUR PRIMARY STRATEGIES DURING THE YEAR?
A. Our ongoing strategy is to maximize total return while maintaining a stable
duration of approximately five years. We attempt to do this while investing only
in securities that are directly or indirectly guaranteed by the U.S. government.

Our goal is to seek returns primarily from income, and we attempt to do that by
investing a significant portion of the portfolio in mortgage-backed securities
that represent good value. Because mortgage-backed durations tend to fluctuate
with changes in interest rates, we constantly adjust the duration of the
portfolio's holdings to maintain a duration of approximately five years.
Generally, this strategy is successful when undervalued mortgage securities
appreciate to their fair value and when interest rate volatility remains low to
moderate.

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 Portfolio is measured against the Lehman
Brothers Government Bond Index, an unmanaged market weighted index that
encompasses U.S. treasury and agency securities with maturities between five and
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 Portfolio
reflects the deduction of these expenses.

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

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

    value by unrealized appreciation (depreciation) of securities as follows:

<Table>

                   Unrealized depreciation......................     (569,464)
                                                                  -----------
                   Net unrealized appreciation (depreciation)...  $38,435,801
                                                                  ===========
</Table>

reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

    Corporation.

Percentages indicated are based on net assets of $60,396,760.

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Non-income producing securities.

(c) Investment in affiliate. Money market fund registered under the Investment
    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

    as part of a security lending transaction.

reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

Percentages indicated are based on net assets of $178,122,873.

    value by unrealized appreciation (depreciation) of securities as follows:

<Table>

</Table>

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

Percentages indicated are based on net assets of $166,027,439.

(a) Represents cost for financial reporting purposes and differs from market
    value by unrealized appreciation (depreciation) of securities as follows:

</Table>

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Non-income producing securities.

(c) Investment in affiliate. Money market fund registered under the Investment
    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

(d) 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. Unless otherwise
    indicated, these securities have been determined to be liquid under
    procedures established by the Board of Trustees.

(e) Security, or a portion of the security, has been delivered to a counterparty
    as part of a security lending transaction.

(f)  Amount rounds to less than 0.1%.

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:

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

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 on 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 December 31, 2004.

See notes to financial statements.

   Aggregate cost for federal income tax purposes differs from cost for
   financial reporting purposes by less than 2% of net assets and is therefore
   considered substantially the same.

(b) Security exempt from registration under Rule 144A for the Securities Act of
    1933. These securities may be resold in transactions exempt from
    registration, normally to qualified institutional buyers.

(c) Investment in affiliate. Money market fund registered under the Investment
    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

(d) Security, or a portion of the security, has been delivered to a counterparty
    as part of a security lending transaction.

(e) Defaulted Security.

<Table>
        
GO -- General
  Obligation
</Table>

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

   Inverse Floaters (IF) represent securities that pay interest at a rate that
   increase (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.

   High Coupon Bonds (HB) (a.k.a. "IOettes") represent the right to receive
   interest payments on an underlying pool of mortgage with similar risks as
   those associated with IO securities. Unlike the IOs the owner also has the
   right to receive a very small portion of principal. The high interest rate
   results from taking interest payments from other classes in the Real Estate
   Mortgage Investment Conduit (REMC) 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 instrument
   rates. As prepayments on the underlying mortgage of these securities
   increase, the yield on the securities increases.

*  The interest rate for this variable rate note, which will change
   periodically, is based on prime rates or an index of market rates. The rate
   reflected on the Schedule of Portfolio of Investments is that rate in effect
   as of December 31, 2004.

See notes to financial statements.

   Aggregate cost for federal income tax purposes differs from cost for
   financial reporting purposes by less than 2% of net assets and is therefore
   considered substantially the same.

(b) Investment in affiliate. Money market fund registered under the Investment
    Company Act of 1940, as amended, and advised by Banc One Investment Advisors
    Corporation.

(c) Security, or a portion of the security, has been delivered to a counterparty
    as part of a security lending transaction.

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

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

SCHEDULE OF PORTFOLIO INVESTMENTS, CONTINUED

   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 instrument
   rates. As prepayments on the underlying mortgage of these securities
   increase, the yield on the securities increases.

*  The interest rate for this variable rate note, which will change
   periodically, is based on prime rates or an index of market rates. The rate
   reflected on the Schedule of Portfolio of Investments is that rate in effect
   as of December 31, 2004.

   financial statements and financial highlights are those of Mid Cap Growth
   Portfolio, Mid Cap Value Portfolio, Diversified Mid Cap Portfolio, Large Cap
   Growth Portfolio, Diversified Equity Portfolio, Equity Index Portfolio,
   Balanced Portfolio, Bond Portfolio and Government Bond Portfolio,
   (individually a "Portfolio", collectively the "Portfolios").

   Under the Trust's organizational documents, its officers and trustees are
   indemnified against certain liabilities arising out of the performance of
   their duties to the Trust. In addition, in the normal course of business, the
   Trust enters into contracts with their vendors and others that provide for
   general indemnifications. The Trust's maximum exposure under these
   arrangements is unknown as this would involve future claims that may be made
   against the Trust. However, based on experience, the Trust expects that risk
   of loss to be remote.

2. SUMMARY OF 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 U.S. generally accepted accounting principles. The
   preparation of financial statements requires management to make estimates and
   assumption that affect the reported amounts of assets and liabilities at the
   date of the financial statements and the reported amounts of income and
   expenses for the period. Actual results could differ from those estimates.

     SECURITY VALUATION

     Listed securities are valued at the closing prices as determined by the
     primary exchange where such securities are traded. Unlisted securities or
     listed securities for which latest sales prices are not available are
     valued at the mean of the latest bid and ask price on the principal
     exchange market or where such securities are normally traded. Corporate
     debt securities, debt securities issued by the U.S. Treasury or U.S.
     government agency (other than short-term investments maturing in less than
     61 days), and municipal securities are valued on the basis of valuations
     provided by dealers or by independent or affiliated commercial pricing
     services approved by the Board of Trustees. Short-term investments maturing
     in less than 61 days are valued at amortized cost, which approximates
     market value. Futures contracts are valued at the settlement price
     established each day by the board of trade or exchange on which they are
     traded. Options traded on an exchange are valued using the last sale price
     or, in the absence of a sale, the mean of the latest bid and ask prices.
     Options traded over-the-counter are valued using dealer-supplied
     valuations. Investments for which the above valuation procedures are
     inappropriate or deemed not to reflect fair value are stated at fair value
     as determined in good faith under procedures approved by the Board of
     Trustees.

     FINANCIAL INSTRUMENTS

     Investing in financial instruments such as futures and indexed securities
     involves risk in excess of the amounts reflected in the Statements of
     Assets and Liabilities. The face or contract amounts reflect the extent of
     the involvement the Portfolios 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, and an illiquid secondary market
     for the instruments or inability of counterparties to perform under the
     terms of the contract. The Portfolios enter into these contracts primarily
     as a means to hedge against adverse fluctuation in the value of securities
     held or planned to be purchased by the Portfolios.

     FUTURES CONTRACTS

     The Portfolios 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. The
     Portfolio's primary purpose in entering into futures contracts is to
     protect that Portfolio from fluctuations in the value of securities without
     actually buying or selling that underlying equity security. Cash or
     securities are deposited with brokers in order to maintain a position.
     Subsequent payments made or received by a Portfolio 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.

     Upon entering into a futures contract, the Portfolios are required to
     pledge to the broker an amount of cash, U.S. government securities or other
     assets, equal to a certain percentage of the contract amount. This is known
     as the initial margin deposit. Subsequent payments, known as variation
     margin, are made or received by the Funds each day, depending on the daily
     fluctuations in fair value of the underlying index. The Funds recognize a
     gain or loss equal to the variation margin.

     The Equity Index Portfolio held the following long futures positions as of
     December 31, 2004:

     REPURCHASE AGREEMENTS

     The Portfolios may invest in repurchase agreements with institutions that
     are deemed by Banc One Investment Advisors Corporation (the "Advisor"), an
     affiliate of JPMorgan Chase & Co., to be of good standing and creditworthy
     under guidelines established by the Board of Trustees. Each repurchase
     agreement is valued at amortized cost. The Portfolios require that the
     collateral received in a repurchase agreement transaction be transferred to
     a custodian in a manner sufficient to enable the Portfolio to obtain the
     collateral in the event of a counterparty default. If the counterparty
     defaults and the fair value of the collateral declines, realization of the
     collateral by the Portfolios may be delayed or limited.

     SECURITIES LENDING

     To generate additional income, each Portfolio may lend up to 33 1/3% of its
     assets pursuant to agreements requiring that the loan be continuously
     secured by any combination of cash, U.S. government or U.S. government
     agency securities, shares of an investment trust or mutual fund, 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 cash collateral
     received by the Portfolios at December 31, 2004 was invested in Repurchase
     Agreements (with interest rates from 2.20 to 2.34% and maturity dates of
     January 3, 2005), Commercial Paper (with interest rates of 2.41%, and a
     maturity dates of March 11, 2005), Certificates of Deposit (with interest
     rates of 2.34%, and a maturity dates of July 26, 2005), and Master Notes
     (with interest rates ranging from 2.15% to 2.58% and maturity dates of
     February 22, 2005 to January 26, 2007). Information on the investment of
     cash collateral is shown in the Schedule of Portfolio Investments. The
     Portfolios receive payments from borrowers equivalent to the dividends and
     interest that would have been earned on securities lent while
     simultaneously seeking to earn income 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 Portfolios or the borrower
     at any time, and are, therefore, not considered to be illiquid investments.

     Prior to October 18, 2004 for all Portfolios except Balanced Portfolio,
     Bond Portfolio, and Government Bond Portfolio (which were prior to December
     6, 2004), the Advisor served as security lending agent. Also, prior to
     those dates, Bank One Trust Company, N.A. served as sub-custodian for the
     securities lending program and received a subcustody fee based on the value
     of collateral received from borrowers.

     On October 18, 2004, the Portfolios' custodian, JPMorgan Chase Bank N.A.
     ("JPMCB") an affiliate of the Portfolios, was appointed as lending agent
     (December 6, 2004 for Balanced Portfolio, Bond Portfolio and Government
     Bond Portfolio). JPMCB receives a fee equal to (i) 6 basis points (.06 of
     1%), calculated on an annualized basis and accrued daily, based upon the
     value of Collateral received from Borrowers for each Loan of U.S.
     Securities outstanding during a given month under this Lending Agreement;
     and (ii) 11.42 basis points (.1142 of 1%), calculated on an annualized
     basis and accrued daily, based upon the value of Collateral received from
     Borrowers for each Loan of non-U.S.

     Securities outstanding during a given month under this Lending Agreement.
     For the period October 18, 2004 (December 6, 2004 for the Balanced
     Portfolio, Bond Portfolio and Government Bond Portfolio) to December 31,
     2004, JPMCB has voluntarily reduced its fees to: (i) 5 basis points (.05 of
     1%) for each Loan of U.S. Securities and (ii) 10 basis points (.1 of 1%)
     for each Loan of non-U.S. Securities, respectively. Risks of delay in
     recovery of securities or even loss of rights in the securities may occur
     should the borrower of the securities fail financially. Risks may also
     arise to the extent that the value of the securities loaned increases above
     the value of the collateral received.

     As of December 31, 2004, the following Portfolios had securities with the
     following market values on loan and for the year then ended, these
     Portfolios paid the following amounts to related party affiliates:

     SECURITIES TRANSACTIONS AND RELATED INCOME

     Investment transactions are accounted for on the trade date (the date the
     order to buy or sell has been executed). 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 includes
     premium amortization and discount accretion for both financial reporting
     and tax purposes. Amortization and accretion are calculated using the
     effective interest method.

     EXPENSES

     Direct expenses of a Portfolio are allocated to that Portfolio. The general
     expenses of the Trust are allocated proportionately among each of the
     Portfolios within the Trust in relation to the net assets of each Portfolio
     or on another reasonable basis.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income, if any, are declared and paid
     annually for the Portfolios. Net realized capital gains, if any, are
     distributed at least annually.

     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.

     FEDERAL INCOME TAX

     The Portfolios' policy is to continue to comply with the requirements of
     the Internal Revenue Code that are applicable to regulated investment
     companies and to distribute all its taxable income to its shareholders.
     Therefore, no federal income tax provision is required.

   The Trust and One Group Administrative Services, Inc., (the "Administrator"),
   an affiliate of JPMorgan Chase & Co. 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 0.18% on the first $250
   million in Trust average daily net assets (other than the assets in the
   Equity Index Portfolio) and 0.14% on Trust average daily net assets in excess
   of $250 (other than the assets in the Equity Index Portfolio). The
   Administrator is entitled to a fee at the rate of 0.14% of the Equity Index
   Portfolio's average daily net assets. Effective February 19, 2005, the
   Administrator was renamed JPMorgan Funds Management, Inc.

   The Portfolios may invest in one or more money market funds advised by
   JPMorgan Investment Advisors Inc. or its affiliates. The Advisor and
   Administrator will waive and/or reimburse their advisory and administrative
   fee, respectively, from the Portfolios in an amount sufficient to offset any
   doubling up of investment advisory and administration fees related to each
   Portfolio's investment in an affiliated money market fund to the extent
   required by law.

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

   The Trust adopted a Trustee Deferred Compensation Plan (the "Plan") which
   allows the independent Trustees to defer the receipt of all or a portion of
   compensation related to performance of their duties as a Trustee. The
   deferred fees are invested in various One Group Mutual Funds until
   distribution in accordance with the Plan.

   On August 12, 2004, the Board of Trustees approved an agreement with JPMCB to
   act as the Portfolios' custodian. The transitions to JPMCB from previous
   service providers were completed on October 18, 2004 for all Portfolios
   except for the Balanced Portfolio, Bond Portfolio and Government Bond
   Portfolio. The transitions for the remaining Portfolios were completed on
   December 6, 2004. The Administrator is responsible for providing fund
   accounting services under the Management and Administration Agreement. Fund
   accounting services were transitioned to JPMCB on October 18, 2004 and on
   December 6, 2004 for the remaining Funds, from their prior service provider,
   but those services are still provided to the Portfolios under such Management
   and Administration Agreement with the Administrator. The amounts paid to

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Shareholders of
One Group Investment Trust

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of portfolio investments, and the related statement of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Mid Cap Growth Portfolio, Mid Cap
Value Portfolio, Diversified Mid Cap Portfolio, Large Cap Growth Portfolio,
Diversified Equity Portfolio, Equity Index Portfolio, Balanced Portfolio, Bond
Portfolio, and Government Bond Portfolio (nine separate portfolios constituting
the One Group Investment Trust, hereafter referred to as the "Trust") at
December 31, 2004, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America. These financial statements and financial
highlights (hereafter referred to collectively as "financial statements") are
the responsibility of the Trust's 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 the standards of the
Public Company Accounting Oversight Board (United States). Those standards
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 December 31, 2004 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

ONE GROUP INVESTMENT TRUST            ANNUAL REPORT            December 31, 2004

INVESTMENT TRUST ANNUAL REPORT
- --------------------------------------------------------------------------------

SCHEDULE OF SHAREHOLDER EXPENSES
HYPOTHETICAL $1,000 INVESTMENT AT BEGINNING OF PERIOD
DECEMBER 31, 2004
(UNAUDITED)

As a shareholder of the Portfolios, you incur ongoing costs, including
investment advisory, administration fees and other Portfolio expenses. The
examples below are intended to help you understand your ongoing costs (in
dollars) of investing in the Portfolios and to compare these costs with the
ongoing costs of investing in other mutual funds. Because the Portfolios are
underlying investment options in variable insurance contracts, contact holders
may also incur transaction costs, such as sales charges and other expenses not
captured here. The examples assume that you had a $1,000 investment in the
Portfolio at the beginning of the reporting period, July 1, 2004, and continued
to hold your shares at the end of the reporting period, December 31, 2004.

ACTUAL EXPENSES
For each Portfolio in the table below, the first line provides information about
actual account values and actual expenses. You may use the information in this
line, together with the amount you invested, to estimate the expenses that you
paid over the period. Simply divide your account value by $1,000 (for example,
an $8,600 account value divided by $1,000 = 8.6), then multiply the result by
the number in the first line of each Class under the heading entitled "Expenses
Paid During Period" to estimate the expenses you paid on your account during
this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line in the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Portfolio's actual return. The hypothetical account values and expenses may
not be used to estimate the actual ending account balance or expenses you paid
for the period. You may use this information to compare the ongoing costs of
investing in the Portfolio and other funds. To do so, compare this 5%
hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs at the Portfolio level only and do not reflect any transaction
costs, such as sales charges (loads) or redemption fees or other expenses
charged by a variable insurance contract. Therefore, the second line for each
Portfolio in the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if the transaction costs and other variable insurance contract
expenses were included, your costs would have been higher. The examples also
assume all dividends and distributions have been reinvested.
